Claims (1)

[Claims] 1. A double floor construction method in which floor boards of standard size are laid and constructed, using a composite floor board in which an auxiliary board is slidably inserted into the end of the floor board, and the auxiliary board is removed from the floor board. A construction method for a double floor, characterized by adjusting the total length of the composite floor board according to the dimensions of the border part by sliding it. 2. The method for constructing a double floor according to claim 1, wherein the composite floor board is constructed by slidably fitting both ends of an auxiliary board between two floor boards. 3. The method for constructing a double floor according to claim 1, wherein the composite floor board is provided with support legs for height adjustment provided on the lower surface of the auxiliary board. [Scope of Claims] [Industrial Application Field] The present invention relates to a method of constructing a double floor, and particularly to a method of constructing a boundary between the floor and a wall surface. [Conventional technology] A double floor is a type of floor in which a space is formed between the slab and the floorboard, and that space is used for computer wiring, etc., instead of placing the floorboards directly on top of the concrete slab. It is a structure. When constructing such a double floor, if you lay standard size floorboards side by side and construct the double floor, there will always be irregular areas near walls or around pillars that do not match the standard size. Theoretically, if the dimensions of the construction site are accurately measured in advance and the parts are cut at the factory, there should be no irregularities. However, considering the actual construction precision, it is impossible to perform construction to that degree. In reality, the floorboards are cut to size on site and separately prepared legs are attached to the underside of the floorboards. [Problems with the conventional technology] The conventional technology as described above is not so difficult when the material of the floorboard is a board made of wood or the like that is easy to cut. However, due to the recent trend towards making interior materials nonflammable,
Cement-based and metal-based plates such as GRC, silica plates, aluminum die-casting, and steel plates are increasingly being used. As a result, on-site cutting and processing work has become difficult due to construction effort, construction time, dust, noise, and other reasons. For this reason, there are many cases in which only the parts that contact walls and pillars that require adjustment are constructed with wood-based materials, without making them fireproof. [Objective of the present invention] The present invention was made in order to improve the conventional problems as described above, and its purpose is to propose a method for constructing a double floor that is easy to adjust and does not require skill. do. Another object of the present invention is to provide a method for constructing a double floor in which the floorboards at boundary areas such as walls and columns can also be constructed using noncombustible materials. [Construction method of the present invention] A construction method of the present invention and members used in the method to solve these problems will be explained. The construction of the present invention is carried out using the auxiliary board 3 and the floorboard 1 having a shape that allows the auxiliary board 3 to be taken in and out from the end face. The floor plate 1 is a plate body having a cross-sectional shape into which an auxiliary plate 3 extending backward from at least one end surface can be slidably fitted. On the other hand, the auxiliary board 3 is a board shaped so that at least one end thereof can be inserted into the end surface of the floorboard 1. In the embodiment shown in the drawings, the floor plate 1 and the auxiliary plate 3
Both use lip channel steel 2 and are constructed so that an auxiliary plate 3 can be fitted into a recess surrounded by a lip 4 at the end of the floor plate 1. In this way, the auxiliary board 3 is inserted from the end of the floorboard 1 to form a composite floorboard A. In this embodiment, a case will be explained in which the floor plate 1 is constructed with a semi-cylindrical shape, but the cross-sectional shape of the floor plate 1 is not limited to this, and may be, for example, a cylinder, etc. In short, the auxiliary plate 3 can be slid freely. Any shape is acceptable as long as it can be fitted inside. That is, the auxiliary board 3 is formed in such a size that it can fit inside the floorboard 1 and slide therein, without leaving much of a gap. The auxiliary plate 3 may have a structure in which support legs 6 are provided protruding from the lower surface, and in that case, the support legs 6 reinforce the bending strength of the auxiliary plate 3. This support leg 6 is attached to the auxiliary plate 3 with a nut 5, for example.
can be constructed by fixing the nut 5 and screwing a bolt into the nut 5. A groove 7 is formed in the upper end of the bolt constituting the leg portion of the support leg 6, and an operation hole 8 is formed in the upper surface of the auxiliary plate 3. The height of the support leg 6 can be adjusted through the operation hole 8 by rotating the bottle of the support leg 6 through the groove 7. When carrying out construction on-site, the weight of the construction site is measured in advance, and floorboards of standard size are laid one after another. Then, the length of the border portion, which is the half-edge portion around walls and pillars where standard size floorboards cannot be laid, is calculated. Prepare a floorboard 1 that is slightly shorter than this length, cut it approximately in the center and divide it into two parts, and divide the auxiliary board 3 between them.
can be slid freely into the interior. The composite floor board A prepared in this way is carried to the site, and the total length of the composite floor board A is adjusted to match the dimensions of the ordered part by sliding the auxiliary board 3 and the floor board 1 as shown in Fig. 3. . Then, both ends of the composite floorboard A are installed between each joist 10 on the slab 9 to close off a space such as near a wall. An auxiliary board is fitted into the recesses on the end faces of the two floorboards 1 and can be inserted and removed freely, so even if the remaining part has irregular dimensions, the floorboard 1 can be placed exactly up to the full height 11 when placed against a wall or pillar. can be installed. At this time, if the exposed auxiliary plate 3 is long, the auxiliary plate 3 is supported from below by the support legs 6. The height of the support legs 6 is adjusted as described above.
This is done by applying rotation to the bolt through the groove 7 from the top of the floor. When the auxiliary board 3 is exposed for a long time from the end surface of the floorboard 1, the support legs 6 may be attached at multiple locations instead of at one location. Furthermore, if the exposed length of the auxiliary plate 3 from the end surface of the floor plate 1 is short and the internal fitting dimension of the auxiliary plate 3 that is fitted into the floor plate 1 is long enough to ensure sufficient supporting force, the support legs 6 may be omitted. good. Furthermore, if the dimension to be fitted into the end surface of the floor plate 1 is long and the dimension to which the auxiliary plate 3 is exposed is short, the auxiliary plate 3
There is no need to fit both sides of the floor plate 1 into the end surface of the floor plate 1, and it is also possible to use only one side by fitting it into the inner fitting part of the floor plate 1. (Fig. 5) When constructed in this way, the auxiliary board 3 will be
The thickness of the part into which the auxiliary board 3 is fitted is lower than that of the floorboard 1. Therefore, we cut a non-combustible thin plate such as a synthetic resin plate that is easy to cut to the dimensions estimated on site.
By pasting it on the auxiliary board 3, the height can be made uniform. Furthermore, in order to securely fix the auxiliary board 3 to the floorboard 1, it is also possible to insert a wedge 13 into the part where the auxiliary board 3 is fitted into the floorboard 1. (Fig. 4) [Effects of the present invention] Since the double floor construction method of the present invention is constructed as described above, the following effects can be achieved. (1) Since there is no need to cut the floorboards on site, length adjustment does not require skill and is extremely easy. (2) The entire floor can be constructed of noncombustible materials.
