     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
       [0002]    The present invention relates to a clip for replacing and repairing a deck and an advanced method of replacing a deck using the same and, more particularly, to a deck fixing device, which can replace a deck with a new deck easily, conveniently and at low cost if a damaged deck is separated from a deck assembly and replaced with the new deck when some of decks are damaged, and a method of replacing a deck using the device. 
         [0003]    The present invention may be applied not only to a deck, but to anyplace, such as a wall, a ceiling, etc., as long as a structural material or finishing material (wood, stone, iron, plastic, ceramic, etc.) can form a shape which a clip may be coupled. 
       2. Description of Related Art 
       [0004]    Wood deck using wood, that is, an eco-friendly material, are selected for the trail of a park, a plaza, the front of a shopping district on a roadside, a hiking trail, the floor pavement of a country house, a building, a wall, etc. and are used in many portions. Compared to other materials, the wood decks are nature-friendly and increase a feeling of walking by efficiently absorbing an impact or vibration. Wood that gives a visually soft and comfortable feeling has advantages of excellent durability and simple maintenance and repair. 
         [0005]    In general, wood deck has been installed by arranging deck on structures, such as lower yokes and support beams arranged on an installation place in a specific shape, and fixing the deck on a deck material using fixing means, such as a nail, a screw, etc. However, such as an installation method had a problem in that it causes inconvenience for a pedestrian or user because the head portion of fixing means, such as a nail, a screw, etc., are upward exposed due to the expansion of wood over time and that it makes poor an external appearance, and also had another problem in that the lifespan of the deck is reduced because moisture penetrates into a portion in which the fixing means has been disposed and the durability of the deck is reduced because a crack phenomenon in which the deck is split due to an erroneous construction of the fixing means is generated. Today, in order to overcome such problems, a method of fixing a deck to an underfloor support beam using a clip for fixing using a side groove between the decks, etc., have been a lot suggested as alternatives and constructed. If the deck or the clip for fixing is damaged, however, the method does not include an alternative for repairing the damaged deck or clip and greatly reduced the lifespan of a wood deck because it depends on a conventional repair method using nail and screw. 
         [0006]    A deck clip used in such a conventional method is representatively described in Korean Patent Application Publication No. 10-2014-0046961. A method of fixing a screw spike, that is, fixing means, to an underfloor support beam when a clip is fixed to a deck material and performing a construction by covering the screw spikes with a secondary deck material was attempted. However, the method had a difficulty in that a deck for replacement had to be pushed and repaired after all of decks in a corresponding column of the deck are pulled out by pushing them because a worker cannot directly separate the screw spike if the deck is to be repaired. 
         [0007]    Meanwhile, in a clip of Korean Utility No. 20-0449555, after the clip is mounted on a deck material and a secondary deck is horizontally moved and mounted on the clip, a screw spike insertion space for fixing a screw spike, that is, a fixing device, had been prepared. The clip had a disadvantage in that a fine view is poor because a wide interval is inevitably generated between the decks in order to prepare a sufficient work space. 
         [0008]    Furthermore, Korean Patent Application Publication No. 10-2011-0102977 has a coupling structure having an excellent effect in the construct ability of a clip. However, the coupling structure has a problem in that it deteriorates the durability of a deck because moisture collected due to rain or dew after a construction is not dried in the deck of a portion with which an underfloor support beam comes into contact in a structure to which the deck and the underfloor support beam have been directly attached. 
         [0009]    Recently, a method capable of replacing only a damaged deck with a new deck by separating the damaged deck using a separate clip for deck replacement has been suggested as the most realistic one alternative as in Korean Patent Application Publication No. 10-2009-0075446. However, the method has disadvantages in that a small number of clips for replacement must be separately used in order to replace a deck and effort and time for obtaining the clip for replacement and incidental expenses, such as corresponding distributions cost, are generated. 
         [0010]    Meanwhile, the applicant filed an application for a repairable clip and a deck repair method using the same in order to improve the above problems as Korean Patent Application No. 10-2015-0010474. The deck clip includes a sheet-shaped fixing portion  100  having a bottom coming into surface contact with a support beam  30 ; a central support portion  203  protruded from the center of the top of the fixing portion  100  to form a reversed T shape with the fixing portion  100 ; a platform for repair  308  formed at the center of the top of the central support portion  203 ; an insert portion  202  formed on the front and rear sides of the platform for repair  308 , extended in the left and right direction and inserted into clip accommodation grooves  22  and  22 ′ of a deck; a clip main body  10  configured to include the storage box of a rotary portion for repair  300  formed in the fixing portion  100  in the left or right direction of the central support portion  203 ; and the rotary portion for repair  300  included in such a way as to be detached from the storage box of the rotary portion for repair  300 . In this case, when the deck is repaired, one end of the insert portion  202  is removed, the rotary portion for repair  300  is separated from the storage box of the rotary portion for repair  300  and mounted on the platform for repair  308 , and the deck is disposed in the fixing portion  100 . Thereafter, one end of the rotary portion for repair  300  is inserted into the clip accommodation grooves  22  and  22 ′ of the deck by rotating the rotary portion for repair  300 , thereby being capable of repairing the deck. Furthermore, an additional function is improved in order for a user and a builder to use and construct a deck more conveniently. 
       BRIEF SUMMARY OF THE INVENTION 
       [0011]    As described above, the applicant of the present application has noticed that the side fixing type clip of a deck is constructed as products of various forms, but there is no deck clip capable of restoration to the original state (repair) conveniently at low cost in most of products if a deck is damaged, and thus the inventors of the present invention has completed the present invention through many idea meetings and the production of samples. 
         [0012]    The present disclosure provides a clip for deck repair capable of convenient, rapid and low-cost restoration to the original state (repair) after only a damaged deck is separated from a deck assembly if some decks are damaged, and a method of replacing a deck using the same. 
         [0013]    However, Korean Patent Application No. 10-2015-0010474 had some portions to be supplemented and reinforced in an installation process actually applied to a deck. The application has a difficulty in construction in a deck commonly having a width of 8 cm or less because fixing portion on one side are symmetrical left and right and thus the space in which a next deck can be continuously disposed is obtained only when the width of the deck must be two times or more of the length of the fixing portion on one side. Furthermore, the application required the adoption of a new construction because there is no configuration for preventing a lateral movement of the deck. The adoption of such a configuration has completed an invention regarding a deck having improved quality and a method of repairing a deck by adopting a configuration which further improves the precision and convenience of the construction. 
         [0014]    In the present invention, in order to immediately practice the replacement of a deck material, a material for repair is inserted and disposed in a product when a deck is first assembled so that an additional material is not required. Accordingly, a deck clip capable of restoration to the original state (repair) has been designed and fabricated. 
         [0015]    Furthermore, a deck repair method capable of rapid and low-cost restoration to the original state (repair), which is convenient for a worker, using the deck clip fabricated as described above has been invented. 
         [0016]    The present disclosure provides a deck clip capable of restoration to the original state (repair), including a rotary portion for repair  300  in a clip main body. 
         [0017]    The deck clip capable of restoration to the original state (repair) according to the present invention may include a fixing portion  100 , a separation support portion  102 , a wing portion  200 , a central support portion  203 , an insert portions  202 ,  202   a  and  202   b , a coupling grooves  101 ,  101   a  and  101   b , and the rotary portion for repair  300 . 
         [0018]    In this case, the rotary portion for repair  300  has a semicircle structure, that is, one surface of a straight-line shape (a rotary portion straight-line edge)  303  and any one structure selected from a circle, oval and polygon structure. A hole (device insertion groove)  301  used upon rotation has been formed near the center. The shape of the hole (device insertion groove)  301  used upon rotation is a polygon. In general, the shape is a square, hexagon or octagon shape. 
         [0019]    Preferably, the rotary portion for repair  300  of the present invention has an embossed protrusion shape which is rotated in the clip accommodation grooves  22  and  22 ′ of the deck on one surface to prevent the deviation of a deck rotated. 
         [0020]    More preferably, the present invention may have a fixing portion that is asymmetrical left and right on the basis of the central support portion  203  and that forms a reversed T shape so that a deck having a small width can be constructed, and may further include a deck fixing hardware insertion groove  103 , a drainage groove  104 , a deck sliding blade  105 , a deck sliding arm  106 , a deck sliding grip  107 , a construction sight groove  205 , a rotation sight groove  311 , deck fixing hardware  400 , a fixing sawteeth  401  and a fixing hardware base  402  as its elements. 
         [0021]    The rotary portion for repair is integrally seated in the clip main body and fabricated. If a deck needs to be repaired, however, the rotary portion for repair is provided so that it can be easily separated from the clip main body and used as a material for repairing a deck. Accordingly, the rotary portion for repair is designed so that a worker can assemble the rotary portion by only a simple task without a separate special difficulty. 
         [0022]    Furthermore, it is preferred that the present invention is equipped with an advanced processing form for an insertion groove so that a replaced deck is seated on the upper side to enable only a damaged deck to be replaced if a deck is to be repaired. 
         [0023]    It is preferred that an installed rotary member can be implemented by a simple tool without a need for a dedicated tool so that it can be practiced by a simple repair task upon installation. In this case, the simple tool may be a wrench formed in a shape, such as a star, square, hexagon or octagon. All of tools may be used as the simple tool if they have a shape capable of applying rotary force. 
         [0024]    It is preferred that the installed rotary member may include a device which can be fixed without being shaken against an external impact or modification even after the rotary member is disposed. 
         [0025]    The installed deck needs to have a proper interval (about 3 mm is preferred) of a construction interval by taking into consideration a value in terms of a fine view according to an excessive interval of deck. Such contents have been taken into consideration. 
         [0026]    A structure is preferred in which the coupling of the deck and the underfloor support beam can be minimized or separated to improve durability of a deck. 
         [0027]    The exemplary embodiment of the present invention, a repair is possible at low cost by fabricating a product to enable a material for repair to be integrated with a construction product so that a separate material is not required when a work for repairing a damaged deck is performed. 
         [0028]    The exemplary embodiment of the present invention, a damaged deck can be separated from a deck assembly and repaired if some decks are damaged, thereby having an effect of restoration to the original state is easily possible and a manager or worker can perform a task rapidly and conveniently. 
         [0029]    Another example of the present invention having an effect of in that it has convenience and high precision of construction in constructing a deck, enhances the stability of a constructed deck, and improve durability of a constructed deck.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0035]    Hereinafter, in the present invention, a deck clip according to the following embodiment and a repair method using the clip are described in detail with reference to the accompanying drawings. 
         [0036]    In describing a preferred exemplary embodiment of the present invention in detail, a detailed description of a known art or configuration will be omitted if it is deemed to make the gist of the present invention unnecessarily vague. Furthermore, if the clip of the present invention has a symmetrical type structure in which the left and the right are the same, a portion that performs the same action of the same form has the same function throughout the drawings although there is no reference numeral in the portion. In an asymmetrical structure, the portion is named so that the function of the portion can be recognized in the name of the reference numeral. 
         [0037]    However, the following exemplary embodiments are provided so that the present invention can be sufficiently understood by a person having ordinary skill in the art. The present invention may be modified in various other forms and the scope of the present invention is not limited to the following embodiment. That is, the exemplary embodiment of the present invention has been provided to describe the invention and should not be construed as limiting the range of right of the present invention. 
         [0038]    Accordingly, the present invention may be applied to a wall, a ceiling in addition to a deck if a structural material or finishing material (wood, stone, iron, plastic, ceramics, etc.,) can form a shape to which a clip may be coupled. 
         [0039]      FIG. 1A  relates to a symmetrical type structure according to an exemplary embodiment of the present invention and is a perspective view of a clip main body  10  that is a deck connection member. As shown in  FIG. 1A , the clip main body  10  that is a deck connection member according to an exemplary embodiment of the present invention is configured to include a fixing portion  100 , a wing portion  200  and a rotary portion for repair  300 . 
         [0040]    In the case of the symmetrical type clip of the present invention, as shown in  FIG. 1A , the clip main body  10  that is a connection member for wood deck includes a sheet-shaped fixing portion  100  having a bottom coming into surface contact with a support beam  30 ; a central support portion  203  protruded from the center of the top of the fixing portion  100  to form a reversed T shape with the fixing portion  100 ; a platform for repair  308  formed at the center of the top of the central support portion  203 ; an insert portion  202  formed on the front and rear sides of the platform for repair  308 , extended in the left and right direction and inserted into clip accommodation grooves  22  and  22 ′ of a deck; a clip main body  10  configured to may include the storage box of a rotary portion for repair  300  formed in the fixing portion  100  in the left or right direction of the central support portion  203 ; and the rotary portion for repair  300  included in such a way as to be detached from the storage box of the rotary portion for repair  300 . In this case, when the deck is repaired, one end of the insert portion  202  is removed, the rotary portion for repair  300  is separated from the storage box of the rotary portion for repair  300  and mounted on the platform for repair  308 , the deck is disposed in the fixing portion  100 , one end of the rotary portion for repair  300  is inserted into the clip accommodation grooves  22  and  22 ′ of the deck by rotating the rotary portion for repair  300 , thereby being capable of repairing the deck. 
         [0041]    An asymmetrical type structure of the present invention is shown in  FIG. 1B . In the case of the asymmetrical type structure in which the left and the right are asymmetrical on the basis of the fixing portion  100  and the reversed T shape, a fixing portion  100   a  may have a semicircular structure on one side and a fixing portion  106   b  may have a triangle on the other side and include the repair portion  300 . 
         [0042]    The present invention may further include a drainage groove  104 . The drainage groove  104  is formed at the back of the fixing portion  100  of the clip and is formed to have a small groove on one side outward from a coupling groove  101  and a deck fixing hardware insertion groove  103 . The drainage groove  104  functions to discharge water or moisture collected in the coupling groove  101  and deck fixing hardware insertion groove  103  of the deck that is exposed to the outside when it rains. Accordingly, durability can be increased by preventing a phenomenon in which the deck is decomposed due to mold generated in the deck. 
         [0043]    A clip sliding blade  105  may be formed at the end of the clip fixing portion  100   a  of the present invention. The clip sliding blade  105  is an angled form having an inclined form. A worker can first hold a clip sliding arm  106  including a clip sliding grip  107  and then easily insert the clip main body into the bottom of an installed deck, thereby increasing working convenience. 
         [0044]    Deck fixing hardware  400  of the present invention has one end bent and protruded. The protruded end is a zigzag sawtooth-shaped structure. A fixture for fixing a movement in one horizontal direction when the deck is fixed by a clip improves construction stability of the deck. 
         [0045]      FIG. 2A  is a plan perspective view and  FIG. 2B  is a rear perspective view of the rotation part for repair  300  that is inserted into and integrated with  FIGS. 1A and 1B . They are described in detail with reference to  FIGS. 6 to 9B . 
         [0046]    A process of forming a deck assembly using the clip main body  10  constructed as above is described again with reference to each drawings. 
         [0047]      FIG. 3A  is a diagram of the configuration of the deck assembly and is a diagram showing the state in which a deck  20  is fixed using the clip main body  10  and a deck  20 ′ on the other side is disposed adjacent to the clip main body  10  in a next step. As shown in  FIG. 3A , after the insert portion  202  is inserted into the clip accommodation groove  22  formed on one side of the deck  20  and closely attached thereto, a piece  40  is vertically inserted into the support beam  30  and fixed to the coupling groove  101 . The coupling grooves  101  has been symmetrically disposed on the left and right sides of the clip, and thus may be differently used depending on an assembly condition. After the piece  40  is fixed to the coupling groove  101 , the deck  20 ′ on the other side is seated in the separation support portion  102  of the clip and horizontally proceeds in the direction of the central support portion  203  of the clip so that the lower side part  21 ′ of the deck  20 ′ on the other side is closely attached to the interval support portion  201  of the clip. Accordingly, the corner of the insert portion  202  has been angled and a straight-line shape protrusion  204 , etc. are present so that the insert portion  202  of the clip can be inserted and fixed to the clip accommodation groove  22 ′ of the deck  20  easily and firmly, thereby being capable of a rapid and accurate assembly. A deck  20  that is subsequently disposed is coupled to the clip main body  10  on one side of the deck  20 , and thus a deck assembly is assembled by repeating such a sequence. 
         [0048]      FIG. 3B  is a side perspective view of the deck assembly. The interval between decks is formed depending on the degree in which the lower side parts  21  and  21 ′ of the deck are closely attached to the interval support portions  201  and  201 ′ of the clip. The interval may be adjusted up to 0-6 mm depending on the processing of the lower side parts  21  and  21 ′ of the deck.  FIG. 3B  is an example showing that the interval between the decks  20  and  20 ′ is 3 mm that is the best in a fine view. Furthermore, the fixing portion  100  of the clip reduces an impact and vibration for the decks between the decks  20  and  20 ′ and the support beam  30  and also couples the decks with them spaced apart at a specific distance, thereby facilitating ventilation. Furthermore, dry can be rapidly performed because a flow of water is free. Furthermore, when the deck  20  and the support beam  30  are coupled, the fixing portion  100  is inserted between the deck  20  and the support beam  30 . Accordingly, the deck  20  is not closely attached to the upper plate of the support beam  30 , but is spaced apart from the upper plate of the support beam  30  at a specific distance by the separation support portion  102  and then coupled thereto, thereby facilitating ventilation. Furthermore, the dry of moisture can be rapidly performed because a flow of water is free. 
         [0049]      FIG. 3C  relates to an installation example of the asymmetrical structure. If decks are continuously disposed using a symmetrical type clip, a clip may not be used because the rectangular fixing portion  100  has a structural restriction by which the fixing portion  100  cannot exceed ½ of the width length of the deck (if a fixing portion on one side is symmetrical left and right, the space in which a next deck can be subsequently disposed is formed only when the width of a deck is two times or more of a fixing portion on one side. Accordingly, a deck commonly having a width of 8 cm or less has a difficulty in construction). In  FIG. 3C  having the asymmetrical structure, the decks may go crisscross each other and may be directly fixed to the top of the support beam straight. Furthermore, a construction sight groove  205  disposed in the clip has a function for allowing a builder to check a corresponding orthogonal situation with his or her eyes so that a clip is seated in a line orthogonal to the support beam when the clip is disposed in the support beam. The construction sight groove  205  eventually has a function for allowing decks to be constructed at constant joint intervals. 
         [0050]      FIGS. 4A and 4B  show an example in which a device for preventing a lateral movement of a deck using the deck fixing hardware  400  has been installed. The deck fixing hardware  400  is installed by inserting it into the deck fixing hardware insertion groove  103  of the clip. The deck fixing hardware  400  has one end bent and protruded, and the protruded end has a zigzag sawtooth-shaped structure. In the sequence of the installation, when a deck on one side is completed (&lt;1&gt;), the deck fixing hardware  400  is inserted into the deck fixing hardware insertion groove  103  of the deck (&lt;2&gt;). In installing a next deck, the zigzag-shaped sawteeth shape is grounded to a portion of the bottom of the side of the next deck, thereby being capable of fixing the next deck while preventing a lateral movement of the deck (&lt;3&gt; and &lt;4&gt;). 
         [0051]      FIGS. 5 to 9B  correspond to the core part of the present invention, and a process of replacing a deck, that is, a target of replacement, with a new deck using the rotary portion for repair  300  integrally included in the clip main body  10  and fixing the new deck when some deck of the deck assembly formed as described above is repaired is described with the drawings. 
         [0052]    A method of repairing a deck according to an exemplary embodiment of the present invention is identically applied to both the symmetrical type and the asymmetrical type, and includes the steps of a) separating a deck, that is, a target of replacement, from a deck assembly; b) cutting one end of the coupling member insert portion  202  in which one end of the deck, that is, the target of replacement, is accommodated; c) separating the rotary portion for repair  300  integrated with the clip fixing portion  100 ; d) seating the separated rotary portion for repair  300  in the platform for repair  308  on the top of the central support portion  203 ; e) coupling a new deck to an empty space; and f) rotating the mounted rotary portion for repair  300  so that it is coupled to the clip accommodation groove  22  of the new deck and an adjacent deck at the same time. 
         [0053]    In  FIG. 5 , the deck  20   a , that is, a target of replacement, is separated from the deck assembly using a jigsaw blade or a rotating sawteeth. 
         [0054]    As shown in  FIG. 6 , the insert portions  202   a  and  202   b  of a clip that belongs to clips in the replacement space part formed after the deck  20   a  that is a target of replacement is separated and that is on the side in which a work is easy are cut to have the same surface as the interval support portion  201  using a sharp knife. A blade cutting part  202   c  is cut to have the same surface as the interval support portion  201 . Next, a connecting rod  307  that fixes the rotation part for repair  300  integrated with the fixing portion  100  of the clip is separated by cutting it using a sharp knife. 
         [0055]    The rotary portion for repair  300  separated in  FIG. 6  is horizontally moved to the platform for repair  308  of the clip so that a rotary portion straight-line edge  303  is shown as  FIG. 7 , and is then inserted up to the clip accommodation groove  22  of the deck and mounted thereon. In this case, the rotary portion straight-line edge  303  is matched to have the same surface as the interval support portion  201  of the clip. 
         [0056]    In  FIG. 8 , after the new deck  20   b  is inserted into a clip on the other side, some pressure is vertically applied so that the new deck  20   b  is seated up to the fixing portion  100  under the clip. 
         [0057]    In  FIG. 9A , a hex wrench  50  is inserted into the device fixing groove  301  of the rotary portion for repair  300 , and the hex wrench  50  is turned 90° so that the rotation part for repair  300  is latched onto both the clip accommodation groove  22  of the deck  20  and the clip accommodation groove  22 ′ of the new deck  20   b  at the same time. In the clip accommodation grooves  22  and  22 ′, the curved shape protrusion  302  of the rotary portion for repair  300  is closely attached to the space, thereby further firming the coupling. In this case, in the present invention, a rotation sight groove  311  (refer to  FIG. 1B ) is further added in order to visually check whether the rotary portion for repair  300  has been accurately turned. 
         [0058]      FIG. 9B  is a diagram illustrating the device for fixing the rotary portion for repair  300  without being shaken in the platform for repair  308  after the rotary portion for repair  300  is mounted. First, a rotation axis protrusion  305  at the center of the bottom of the rotary portion for repair  300  is seated and fixed to the rotation axis groove  309  of the platform for repair  308  so that the rotary portion for repair  300  is stably turned and fixed after being installed. A rotation axis fixing protrusion  306  at the bottom of the rotary portion for repair  300  is seated and fixed to the fixing groove  310  of the platform for repair  308  so that the rotary portion for repair  300  is not detached after being mounted, and can maintain the function. Such a device may be said to be a minimum required measure which facilitates the work of replacing a deck and also enables a deck to be certainly mounted. 
         [0059]    After a damaged deck, that is, a target of replacement, is separated from an assembly using such a method, a new deck can be conveniently mounted. 
         [0060]    The aforementioned preferred exemplary embodiment of the present invention has been disclosed for an illustrative purpose, and a person having ordinal skill in the art to which the present invention pertains may modify, change and add the embodiment within the spirit and range of the present invention and such modification, change and addition should be construed as belonging to the claims of this document.
