Description: Improvements in a prefabricated sectional residence block The present invention relates to the field of the prefabricated residence rooms and particularly to a sectional block for the construction of lodgings consisting of one or more rooms by connecting and/or superimposing several blocks. A large number of prefabricated blocks characterized by assembling and disassembling systems which are quite different from one another are known. Particularly, it is known a type of prefabricated sectional block which is provided with interchangeable walls that can be assembled and disassembled from the outside without having to remove roof and corners and capable of being transported taking up a much lower room than that of an assembled block since it is provided with a wholly flat roof which allows it to be overlapped. A first problem of such known blocks is that, in case of their installation in sites under particularly bad weather conditions, a water infiltration from the covering may occur causing discomforts and damages both to occupants and things. A second problem of the above-mentioned blocks is that the possibilities of connecting and combining several blocks are limited by the fact that such blocks can be coupled only by superimposing and/or placing them side by side along their long sides so that the type of the residence rooms cannot be chosen at will. Still another drawback of such known blocks is that the flooring consists of a wooden chip panel that does not guarantee a sufficient insulation especially under rigorous climate. Therefore, one aim of the present invention is to provide a block having a covering that guarantees a perfect tightness to bad weather as well as an optimum insulation even though the capability to be moved and the readiness of installation is maintained. A second aim of the invention is to pro.idc a block characterized by a capability of being connected horizontally and/or vertically without any limit of dimension and/or arrangement of the residence rooms. Still another aim of the disclosed sectional block is to guarantee, if necessary, an optimum insulation also as far as the flooring is concerned. Such aims are achieved according to the invention by providing a block of the type having a carrying structure including a basement, a roof, and supporting angle section bars or columns removably secured to such basement and roof, suitable panels forming the walls being secured to the carrying structure by section bars that can be disassembled from the outside, characterized by the fact that it is provided with a double-pitch covering separated from the insulating underlying panel as well as with an insulating flooring panel, and that it is capable of being placed side by side to other blocks not only parallel but also perpendicular to one another. Particularly, such covering has a height and a shape such as to keep the overall dimension of the block unchanged. A better understanding of the invention will ensue from the following detailed description with reference to the accompanying drawings that show only by way of a not limiting example a preferred embodiment of the invention . In the αrawings : Fig. 1 is top plan view of the block according to the invention; Figs. 2, 3 and 4 are details in longitudinal vertical sections along a plane A-A that show the fastening of the sheet to the covering panel; Fig. 5 is a plan view of an example of coupled blocks; Fig. 6 is a front, view of the coupled blocks of Fig. 5; Figs . 7 and 8 are schematic plan views of examples for connecting the blocks according to the invention; Fig. 9 is a schematic perspective view of the coupling among parallel and perpendicular blocks; Figs. 10 and 12 are a longitudinal section and a cross section of a block, respectively; and Figs. 11 and 13 are detailed views of Figs. 10 and 12, respectively. With reference to Figs. 1-4, the block according to the invention has an upper covering including a rectangular rigid frame T formed by four section bars 1 welded at right angles to one another and having such a section as to perform the double lu-i-lion ox carrying structure and drainage of the rain water, as better shown in Figs. 3 and 4. A horizontal sandwich panel 2 able to guarantee the insulation of the top of the block is secured inside the rectangular frame T, while a double-pitch covering 3, preferably of zinc-plated fret sheet, is secured above such panel, said covering being capable of protecting the underlying parts from the bad weather as well as allowing rain water to flow to two opposite sides of the rectangular frame so that it can flow down into the already described section bars 1. In order to avoid the problem of water infiltration at the outlet from sheet 3 to section bars 1 of the rectangular frame, the lower ends of such fret sheet 3 are secured to a corresponding section bar 5 which is placed between such sheet and sandwich panel 2 and surrounds completely the edge of the panel itself. C θil u invention the ridge of the covering sheet 3 does not project from the plane through the upper edge of the above-mentioned rectangular frame T. This allows a double-pitch covering to be used while keeping the overall dimension both during the transport and the installation and use of the blocks unchanged. Advantageously a hollow space 4 is formed between sandwich panel 2 and fret sheet 3 so that the thermal exchange between the inside of the residence block and the outside is further reduced. Finally, an upper section bar 6 provided with holes for fastening any upper blocks and/or tianspo Ling che block and a lower section bar 10 able to be coupled to corresponding angle columns 11 are provided at the four corners of the rectangular frame, respectively. According to a further advantageous feature of the invention it is possible to connect several blocks of the disclosed type without any limitation of the possible combinations. With particular reference to Figs. 5 to 9 the present invention provides two types of blocks which differ from each other in length: actually, one of them has a length which is double as long as its width. Such a construction feature is particularly important as it allows the blocks to be positioned both along the major sides and the minor sides by using blocks of the above type and positioning them perpendicular to the others, as shown in the above-mentioned figures. It should be appreciated that such a feature has a -- - " li iuc i αuic nψυi -αiitc i dol *---- -- SJ -.--<-: v ci bα -lii L^ Lj which it is possible to arrange blocks and residence rooms that are then net restricted in width and/or length and always keep the capability of being connected also vertically, i.e. the capability of being superimposed. In other words, according to the invention it is possible to provide rooms of any size by installing only the peripheral walls and suppressing the inside walls between one block and the adjoining block. The basement of the disclosed block essentially consists of a rectangular frame S on which a wooden chip panel 8 and cxoove the latter a flooring 7 preferably of PVC is located. Like the covering disclosed above, rectangular frame S of the basement is provided at its corners with upper members 12 projecting from the upper side and capable of being coupled to the lower ends of angle columns 11, and with lower members 13 provided with holes capable of being coupled to the already disclosed section bars 6 when the blocks are superimposed. Still another new feature of the invention consists in that a further insulating sandwich panel 9 is provided under flooring 7 and wooden chip panel 8 so as to considerably improve the insulation of the block from the ground as well as increase the comfort of the occupants of the residence rooms obtained by the block according to the invention. Finally, in case the blocks are superimposed, it is possible according to the invention to provide a l uI Lnc L *--c: c-(-ic;---L--y ane -. O _-Q L CU UC -. c-i wOOucii Cul j j panel 8 and insulation panel 9 in the upper block so that walking in the room of the upper block does not produce any troublesome noise which can be heard in the room of the lower block. The present invention is described and illustrated according to a preferred embodiment thereof, however, it should be understood that changes and/or equivalent replacements can be made by those skilled in the art without departing from the scope of the present industrial invention.
