Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a packaging structure for building boards used for an external wall or interior wall of a house and a building boards loading structure. 
     2. Description of the Related Art 
     The following description sets forth the inventor&#39;s knowledge of related art and problems therein and should not be construed as an admission of knowledge in the prior art. 
     In general, a building board is used for wall material or roofing material of a house. 
     As for the building board, a package is applied for protecting it from breakage and dirt when it is kept and it is carried in an installation site. In consideration of workability, it is general to pack two or three building boards in one package, the plural packages are loaded on a pallet, and it is kept or it is carried. 
     In general, for a pallet to be loaded with the plural packages, as shown in  FIG. 17 , plural stringers  10  are arranged by predetermined spacing, and plural deck boards  11  are fixed by nail on a top face and undersurface of the stringer  10 . Entry  12  to insert a fork of a fork lift truck is made from the stringer  10  and the deck board  11  is installed in the pallet. The package is loaded on the pallet, and the package can be moved with a fork lift truck by inserting a fork of a fork lift truck in entry  12 . 
     In addition, there are numerical quantities of building board loaded pallets which are different by weight, shape and thickness. Furthermore, when it is transported to an installation site, a picking up work operation is performed to adjust the building boards to the numerical quantity that is necessary. 
     As a representative example of the above described building board, there is a rectangle-shaped fiber reinforced cement siding having 455 mm of width and 1500-3030 mm of overall length and 9-25 mm of thickness. In the case of the above described fiber reinforced cement siding, a fiber reinforced cement siding which has a surface (a design patent side) and an under face on the back side is piled up on another fiber reinforced cement siding having a surface of a top face, and one packaging structure is made of the two fiber reinforced cement sidings. So, each other&#39;s surface of the fiber reinforced cement siding is made face-to-face, and it is not exposed. Therefore, each other&#39;s surface of the fiber reinforced cement siding is protected. In addition, in the case of fiber reinforced cement siding having a convexoconcave shank design in the surface or having a coating surface, the surface is protected more by using inserting paper between the two fiber reinforced cement sidings. A size of the inserting paper to use for this case is more massive than the size of the whole surface of the above described fiber reinforced cement siding. 
       FIG. 14  is a view which shows a packaging structure for building boards and a building boards loading structure according to a related art.  FIG. 14  ( a ) shows a perspective view of package A 141  of fiber reinforced cement sidings  1  as building boards,  FIG. 14  ( b ) shows a perspective view of a loading structure having loaded pallet B with packages A 141 . 
     As shown in  FIG. 14  ( a ), package A 141  has a structure in which two pieces of fiber reinforced cement siding  1  are piled up to be sandwiching an inserting paper  2 , and it is covered overall by shrink film  6 , as shown in  FIG. 14  ( b ), packages A 141  are loaded on pallet B with two lines. 
       FIG. 15  is a view which shows a packaging structure for building boards and a building boards loading structure according to a related art (Japanese Patent Laid-Open No. 2005-231713 is referred to).  FIG. 15  ( a ) shows a perspective view of package A 151  of fiber reinforced cement sidings  1  as building boards,  FIG. 15  ( b ) shows a perspective view of a loading structure having loaded pallet B with packages A 151 . 
     As shown in  FIG. 15  ( a ), package A 151  has a structure with two pieces of fiber reinforced cement siding  1  piled up with attaching paper cushioning material  5 ,  5  on either side of a longer direction of the two pieces of fiber reinforced cement siding  1 , and capping paper cap  7 , 7  on either side of a short direction of the two pieces of fiber reinforced cement siding  1 , and banding of two pieces of the fiber reinforced cement siding  1  by plural polypropylene-made bands  3 . As shown in  FIG. 15  ( b ), packages A 151  is a loaded pallet B with two lines, and a location of polypropylene-made band  3  banding package A 151  is the same in all package A 151 . 
       FIG. 16  is a view which shows a packaging structure for building boards and a building boards loading structure according to a related art (Japanese Patent Laid-Open No. 2005-231713 is referred to).  FIG. 16  ( a ) shows a perspective view of package A 161  of fiber reinforced cement sidings  1  as building boards,  FIG. 16  ( b ) shows a perspective view of a loading structure having loaded pallet B with packages A 161 . 
     As shown in  FIG. 16  ( a ), package A 161  has a structure in which two pieces of fiber reinforced cement siding  1  are piled up with banding at ends of two pieces of fiber reinforced cement siding  1  by shrink film  6 , 6 . In this case, shrink film  6  is heated, and it shrinks. Furthermore, a slip resistance means using hot melt  8  is put on a top of shrink film  6 . And, as shown in  FIG. 16  ( b ), packages A 161  are loaded on pallet B with two lines. 
     However, in package A 141  and the loading structure shown in  FIG. 14 , there is no point for catching package A 141 , so it is difficult to pick up package A 141  from pallet B. In addition, when plural packages A 141  are loaded, it is difficult to pick up package A 141  because a shrink film  6  of package A 141  is made to stick to another shrink film  6  by static electricity which occurs by rubbing. 
     Furthermore, a work operation which opens package A 141  to use the fiber reinforced cement siding  1  at an installation site is necessary. In the packaging structure of package A 141 , shrink film  6  must be stripped, and fiber reinforced cement siding  1  must be transferred to another pallet for removing stripped shrink film  6 , so that an effort and time are needed for this operation. 
     Furthermore, shrink film  6  after stripping is unnecessary so that it becomes industrial waste, and it is uneconomical. 
     On the other hand, in package A 151  and the loading structure shown in  FIG. 15 , it is easy to pick up package A 141  from pallet B by catching the polypropylene-made band which bands ends of the two pieces of fiber reinforced cement siding  1 . In addition, at an installation site, a work operation which strips and removes shrink film  6  of package A 151  is unnecessary and a problem that shrink film  6  after stripping becomes industrial waste does not occur. 
     However, package A 151  uses paper cap  7 , so that a packaging cost rises, and productivity in the factory falls. In addition, at an installation site, paper cap  7  must be stripped of package A 151 , and the fiber reinforced cement siding  1  must be transferred to another pallet for removing stripped paper cap  7 , so that an effort and time are needed for an operation. Furthermore, paper cap  7  after stripping is unnecessary so that it becomes industrial waste, and it is uneconomical. 
     Furthermore, a location of polypropylene-made band  3  banding package A 151  is the same in all packages A 151 , as shown in  FIG. 15  ( b ), plural packages A 151  are loaded on pallet B, and only one point of polypropylene-made band  3  becomes a point to rise from other points, by piling up plural polypropylene-made bands  3 , so that a load tends to be concentrated at a point of polypropylene-made band  3 . It is remarkable for lifting pallet B which loads plural packages A 151 . It makes unfavorable brightness and micro cracks at the surface of the fiber reinforced cement siding  1 , and it might lose a good appearance and the good quality of the fiber reinforced cement siding  1 . 
     In addition, an antislip agent is not applied between each package A 151  loaded and, package A 151  is mobile when receiving a force, so that the loading structure shown in  FIG. 15  is easy to collapse. 
     Furthermore, in package A 161  and the loading structure shown in  FIG. 16 , packing material is only shrink film  6  with bands at both ends of package A 161  and hot melt  8 , thus packaging cost can be low and controlled. But when package A 161  is picked up, package A 161  bends greatly because package A 161  bands only at both ends, so that the fiber reinforced cement siding  1  might be damaged during a picking up operation. In addition, it is difficult to pick up shrink film  6  because it was heated and shrinks. 
     Furthermore, a location of shrink film  6  banding package A 161  and hot melt  8  are the same in all package A 161 , as shown in  FIG. 16  ( b ). Plural packages A 161  are loaded on pallet B, and only one point of shrink film  6  becomes a point to rise from other points, by piling up plural shrink films  6  and hot melt  8 , so that a load tends to be concentrated at a point of shrink film  6 . It is remarkable for lifting pallet B which loads plural packages A 161 . As in the loading structure of  FIG. 15 , it makes unfavorable brightness and micro cracks at a surface of the fiber reinforced cement siding  1 , and it might lose a good appearance and quality of the fiber reinforced cement siding  1 . 
     The description herein of advantages and disadvantages of various features, embodiments, methods, and apparatus disclosed in other publications is in no way intended to limit the present invention. For example, certain features of the preferred embodiments of the invention may be capable of overcoming certain disadvantages and/or providing certain advantages, such as, e.g., disadvantages and/or advantages discussed herein, while retaining some or all of the features, embodiments, methods, and apparatus disclosed therein. 
     SUMMARY OF THE INVENTION 
     The preferred embodiments of the present invention have been developed in view of the above-mentioned and/or other problems in the related art. The preferred embodiments of the present invention can significantly improve upon existing methods and/or apparatuses. 
     Among other potential advantages, some embodiments can provide a packaging structure for building boards and a building boards loading structure, which is hard to collapse, and which does not make unfavorable brightness and micro cracks at a surface of the building boards, and its packaging cost is low, and its productivity and picking up workability do not deteriorate, and workability at an installation site is preferable, and industrial waste after unpacking is little. 
     According to some embodiments of the present invention, in a packaging structure for building boards which packs plural building boards in one package, the packaging structure comprises a plural of building boards and plural bands, and the plural of building boards are banded at plural locations by the plural bands, and a surface of the bands which are located at both ends of the packaging structure is adhesive, and a surface of band which are located at both ends of the packaging structure is non-adhesive. 
     An example of the band in which the surface is adhesive is a resin-made film such as stretch film and shrink film having a tacky producer in the surface, a resin-made band such as a band made of polypropylene and polyethylene having a tacky producer in the surface. On the other hand, an example of the band in which the surface is non-adhesive is a resin-made film having no tacky producer in the surface and a resin-made band having no tacky producer in the surface. In addition, the tacky producer always has tackiness in an absence of a solvent condition, and an example of the tacky producer is crude-rubber and synthetic rubber, acryl, and liquid aliphatic hydrocarbon. 
     When plural packages having said packaging structure are loaded on a pallet, a surface of the bands located at both ends of the package is adhesive, so that it is hard to collapse because of sticking of the bands. And when a surface of the band which is located between both ends of the packaging structure is non-adhesive, cutting the band and difficulty of picking up caused by sticking of the band to another band does not occur. 
     Furthermore, it is a minimum package, so that packaging cost is cheap, and productivity does not deteriorate. Unpacking at an installation site is only by cutting the plural bands, and it is not necessary to transfer plural building boards to another pallet, and industrial waste after unpacking is little. And it is easy to pick up a package from a pallet by catching the band. 
     Furthermore, in the packaging structure for building boards, a band is located between both ends of the packaging structure and bands the building boards helically. 
     In the packaging structure, the band is located between both ends of the packaging structure and bands the building boards helically, so that a banding force of the package becomes strong. And, even if force was added to the package from the outside, upper and lower building boards slipping off in the package is controlled. 
     According to some embodiments of the present invention, in a packaging structure for building boards which packs plural building boards in one package, the packaging structure comprises plural building boards and plural bands, and the plural building boards are banded at plural locations by the plural bands, and a surface of all bands is adhesive. 
     An example of the band in which the surface is adhesive is a resin-made film having a tacky producer in the surface and a resin-made band having a tacky producer in the surface. 
     When plural packages having said packaging structure are loaded in a pallet, a surface of all bands in the package is adhesive, so that it is hard to collapse because of sticking of the bands. 
     Furthermore, it is a minimum package, so that packaging cost is cheap, and productivity does not deteriorate. Unpacking at an installation site is only cutting the plural bands, and it is not necessary to transfer plural building boards to another pallet, and industrial waste after unpacking is little. And, it is easy to pick up a package from a pallet by catching the band. 
     Furthermore, in the packaging structure for building boards, a band which is located between both ends of the packaging structure bands the building boards helically. 
     In the packaging structure, the band which is located between both ends of the packaging structure bands the building boards helically, so that a banding force of the package by the band becomes strong. And, even if a force was added to the package from the outside, upper and lower building boards slipping off in the package is controlled. 
     Furthermore, in the packaging structure for building boards, the bands are resin-made film. 
     By using resin-made film as the band, a package having the packaging structure is banded enough, and an effect of the invention can be shown. In addition, resin-made film is more flexible than a resin-made band, and a thickness of the resin-made film is thin, so that a load by banding building boards can be minimized, and unfavorable brightness and micro cracks at the surface of the building boards is controlled. 
     According to some embodiments of the present invention, in a building boards loading structure which loads plural building boards on a pallet, the building boards loading structure comprises plural packages, and the package comprises plural building boards and plural bands, and the plural building boards are banded at plural locations by the plural bands, and the plural packages are loaded on the pallet, and the location of bands in each upper and lower package which is loaded on the pallet is different from each other. 
     An example of the band is a resin-made film such as stretch film and shrink film, a resin-made band such as a band made of polypropylene and polyethylene, a paper-made band and a cloth-made band. 
     In the building boards loading structure, the location of the bands in each upper and lower package which is loaded on the pallet is different from each other, so that it prevents a load from concentrating the location of the bands, and it does not make unfavorable brightness and micro cracks at the surface of the building boards. 
     And, even if using resin-made film as a band of the package, cutting the band and difficulty of picking up by sticking of the band to another band does not occur. 
     Furthermore, it is a minimum package, so that packaging cost is cheap, and productivity does not deteriorate. Unpacking at an installation site is only cutting the plural bands, and it is not necessary to transfer plural building boards to another pallet, and industrial waste after unpacking is little. And, it is easy to pick up a package from the pallet by catching the band. 
     Furthermore, in the building boards loading structure at least one of the bands bands the building boards helically. 
     A resin-made film such as stretch film and shrink film, a resin-made band such as a band made of polypropylene and polyethylene, a paper-made band and a cloth-made band are used as the band. Especially, using the resin-made film as the band is preferable. 
     In the packaging structure, at least one of the bands bands the building boards helically, so that the banding force of the package by bands becomes strong. And, even if a force was added to the package from the outside, upper and lower building boards slipping off in the package is controlled. 
     Furthermore, in the building boards loading structure, the pallet comprises plural stringers and plural deck boards, and the plural stringers and plural deck boards make an entry to insert a fork of a fork lift truck, and the location of bands in a lowest package which is loaded on the pallet is different from an upper location of the stringers and inserting fork of the fork lift truck. 
     In the building boards loading structure, the effect is that it prevents a load from concentrating at the location of bands and it does not make unfavorable brightness and micro cracks at the surface of the building boards is increased. 
     According to some embodiments of the present invention, in a building boards loading structure which loads plural building boards on a pallet, the building boards loading structure comprises plural packages, and the package comprises plural building boards and plural bands, and the plural building boards are banded at plural locations by the plural bands, and the plural packages are loaded on the pallet, and the pallet comprises plural stringers and plural deck boards, and the plural stringers and plural deck boards make an entry to insert a fork of a fork lift truck, and the location of the bands in a lowest package which is loaded on the pallet is different from an upper location of the stringers and the inserting fork of the fork lift truck. 
     A resin-made film such as stretch film and shrink film, a resin-made band such as a band made of polypropylene and polyethylene, a paper-made band and a cloth-made band are used as the band. 
     When the pallet loaded with the package moves with a fork lift truck, the load tends to be concentrated at a point of an upper location of the stringers and the inserting fork of the fork lift truck. 
     However, in the building boards loading structure, the location of bands in a lowest package which is loaded on the pallet is different from an upper location of the stringers and the inserting fork of the fork lift truck, so that it prevents a load from concentrating at the location of the bands, and it does not make an unfavorable brightness and micro cracks at the surface of the building boards. 
     Furthermore, it is a minimum package, so that packaging cost is cheap, and productivity does not deteriorate. Unpacking at an installation site is only cutting the plural bands, and it is not necessary to transfer plural building boards to another pallet, and industrial waste after unpacking is little. And, it is easy to pick up the package from the pallet by catching the band. 
     Furthermore, in the building boards loading structure the bands are resin-made film and/or a resin-made band. 
     An example of the band is a resin-made film such as stretch film and shrink film, and a resin-made band such as a band made of polypropylene and polyethylene. 
     By using a resin-made film and/or resin-made band as the band, a package is banded enough, and the effect of the invention can be shown. 
     According to some embodiments of the present invention, in a building boards loading structure which loads plural building boards on a pallet, the building boards loading structure comprises plural packages, and the package comprises plural building boards and plural bands, and the plural building boards are banded at plural locations by the plural bands, and a surface of bands which are located at both ends of the package is adhesive, and the plural packages are loaded on the pallet, and the pallet comprises plural stringers and plural deck boards, and the plural stringers and plural deck boards make an entry to insert a fork of a fork lift truck, and the location of the bands at both ends of the package in each upper and lower package which is loaded on the pallet is the same, and it is different from an upper location of the stringers and the inserting fork of the fork lift truck. 
     In the building boards loading structure, a surface of bands which are located at both ends of the package which is loaded on the pallet is adhesive, and the location of the bands at both ends of the package in each upper and lower package which is loaded on the pallet is the same, so that it is hard to collapse because of sticking of the bands. 
     If a location of the bands in the package in each upper and lower package which is loaded on the pallet is the same, a point of the bands becomes a point to rise from other points by piling up plural bands, so that a load tends to be concentrated at a point of the band. It is remarkable for lifting a pallet which loads plural packages. However, in the building boards loading structure, a location of bands at both ends of the package in each upper and lower package which is loaded on the pallet is different from an upper location of the stringers and an inserting fork of the fork lift truck, so that it prevents a load from concentrating at the location of the bands, and it does not make unfavorable brightness and micro cracks at the surface of the building boards. 
     Furthermore, it is a minimum package, so that packaging cost is cheap, and productivity does not deteriorate. Unpacking at an installation site is only cutting the plural bands, and it is not necessary to transfer plural building boards to another pallet, and industrial waste after unpacking is little. And, it is easy to pick up the package from pallet by catching the band. 
     Furthermore, in the building boards loading structure the location of the bands between both ends of the package in a lowest package which is loaded on the pallet is different from an upper location of the stringers and the inserting fork of the fork lift truck. 
     In the building boards loading structure, the location of the bands between both ends of the package in a lowest package which is loaded on the pallet is different from an upper location of the stringers and the inserting fork of the fork lift truck, it prevents a load from concentrating at the location of all bands and it does not make unfavorable brightness and micro cracks at the surface of building boards. 
     Furthermore, in the building boards loading structure the location of the bands between both ends of the package in each upper and lower package which is loaded on the pallet is different from each other. 
     In the building boards loading structure, the location of bands between both ends of the package in each upper and lower package which is loaded on the pallet is different from each other, it prevents a load from concentrating at the location of all the bands and it does not make unfavorable brightness and micro cracks at the surface of the building boards. 
     And, even if using a band having an adhesive surface, cutting the band and difficulty of picking up caused by sticking of the band to another band does not occur. 
     Furthermore, in the building boards loading structure the bands are resin-made film. 
     An example of the resin-made film is stretch film and shrink film. 
     By using resin-made film as the band, a package is banded enough, and the effect of the invention can be shown. 
     EFFECT OF THE INVENTION 
     According to the present invention, it is a minimum package, so that packaging cost is cheap, and productivity does not deteriorate.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     In the following paragraphs, some preferred embodiments of the invention will be described with reference to the attached drawings by way of example and not limitation. It should be understood based on this disclosure that various other modifications can be made by those in the art based on these illustrated embodiments. 
     A packaging structure for building boards and a building boards loading structure according to a preferable embodiment of the present invention will be explained with reference to  FIGS. 1 to 13 . 
     Embodiment 1 
       FIG. 1  is a view which shows a packaging structure for building boards and a building boards loading structure according to the first embodiment of the present invention.  FIG. 1  ( a ) shows a perspective view of packages A 11  and A 12  of fiber reinforced cement sidings  1  as building boards, and  FIG. 1  ( b ) shows a perspective view of a loading structure with loaded pallet B having packages A 11  and A 12 . 
     As shown in  FIG. 1  ( a ), packages A 11  and A 12  have a structure in which two pieces of fiber reinforced cement siding  1  are banded by plural polypropylene-made bands  3 . As an example, a number of polypropylene-made bands  3  in one package which is package A 11  or A 12  is four. When packages A 11  and A 12  are loaded on pallet B, a location of the polypropylene-made bands  3  is different from an upper location of the stringers and an inserting fork C of a fork lift truck. In addition, packages A 11  and A 12  are different from a location of the polypropylene-made bands  3 , so that a location of the polypropylene-made bands  3  in each upper and lower package which is loaded on the pallet is different from each other by loading a package A 11  with a package A 12  alternately. As shown in  FIG. 1  ( b ), packages A 11  and A 12  are arranged in two lines, wherein packages A 11  and A 12  are loaded on pallet B alternately, so that a location of the polypropylene-made bands  3  in each upper and lower package which is loaded on the pallet is different from each other, and a location of the polypropylene-made bands  3  is different from an upper location of the stringers  10  and the inserting fork C of a fork lift truck. Therefore, it prevents a load from concentrating at the location of all the polypropylene-made bands  3  and it does not make an unfavorable brightness and micro cracks at the surface of the fiber reinforced cement sidings  1 . 
     And, it is easy to pick up packages A 11  and A 12  from pallet B by catching the polypropylene-made band  3 . 
     Furthermore, packages A 11  and A 12  are minimum packages, so that packaging cost is cheap, and productivity does not deteriorate. Unpacking at an installation site is only cutting the plural polypropylene-made bands  3 , and it is not necessary to transfer plural fiber reinforced cement sidings  1  to another pallet, and industrial waste after unpacking is little. 
     Embodiment 2

       FIG. 13  is a view which shows a packaging structure for building boards and a building boards loading structure according to the thirteenth embodiment of the present invention.  FIG. 13  ( a ) shows a perspective view of packages A 131  and A 132  of fiber reinforced cement sidings  1  as building boards, and  FIG. 13  ( b ) shows a perspective view of a loading structure on loaded pallet B having packages A 131  and A 132 . 
     Packages A 131  and A 132  are the same as packages A 121  and A 122  except stretch films are between both ends of the package. 
     As shown in  FIG. 13  ( a ), the stretch film which is located between both ends of packages A 131  and A 132  is stretch film  4   b  having a non-adhesive surface, and a location of the stretch film  4   b  which is located between both ends of package A 131  is different from package A 132 , and a location of the stretch films  4   b  in between both ends of the package A 131  which is loaded on the pallet B is different from an upper location of the stringers  10  and inserting fork C of a fork lift truck. 
     As shown in  FIG. 13  ( b ), a lowest package which is loaded on the pallet B is package A 131 , a location of the stretch films  4   b  is in between both ends of the package in each upper and lower package which is loaded on the pallet B is different from each other by loading a package A 131  with a package A 132  alternately. Therefore, it prevents a load from concentrating at the location of all the stretch films  4   a  and  4   b , and it does not make an unfavorable brightness and micro cracks at the surface of the fiber reinforced cement sidings  1 . And, cutting the band and difficulty of picking up by sticking of the band to another band does not occur. 
     And, a surface of the stretch films  4   a  which is located at both ends of the packages A 131  and A 132  which is loaded on the pallet B is adhesive, and the location of the stretch films  4   a  at both ends of the package in each upper and lower package which is loaded on the pallet B is the same, so that it is hard to collapse because of sticking of the packages A 131  and A 132 . 
     And it is easy to pick up packages A 131  and A 132  from pallet B by catching the stretch film  4   a.    
     Furthermore, packages A 131  and A 132  are a minimum package, so that packaging cost is cheap, and productivity does not deteriorate. Unpacking at an installation site is only cutting the plural stretch films  4   a  and  4   b , and it is not necessary to transfer plural fiber reinforced cement sidings  1  to another pallet, and industrial waste after unpacking is little.
