Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure of a side end portion of a floor body of a building material unit that allows a heat insulating material to be arranged between the floor bodies of adjacent building material units in a form that is extremely easy to construct.

The outer periphery of the floor is made of steel such as H steel or C-shaped steel, with a horizontal recess formed on the outside, and the floor is heat-insulated, and the corner of the floor is erected. When constructing a building by connecting and installing multiple building material units consisting mainly of hollow columns at a construction site, it is normal for there to be a slight gap between the floor bodies of adjacent building material units due to the design. Therefore, it is desirable to provide a heat insulating material between the floor bodies and separately cover the upper part of the heat insulating material with a floor material. Therefore, when installing the above-mentioned heat insulating materials, placing the insulating materials one by one between the floor bodies is difficult because the gaps between the floor bodies are narrow and there may be horizontal recesses on the outside of the floor bodies. However, it is time-consuming and undesirable from the viewpoint of saving labor in on-site construction work.

In this invention, the side edges of the floors of one building material unit are modified so that the insulation material can be placed between the floors of adjacent building material units in a form that is extremely easy to install. A structure of a side end of a floor body of a building material unit is provided, in which a heat insulating material is housed in the horizontal recess shaped like a steel material on the outer periphery of the floor body, and the outside of the heat insulating material is covered with a sheet such as a resin sheet. Thus, during use, the heat insulating material can be placed between the steel members by simply separating the upper edge of the sheet from the upper horizontal portion of the steel member.

EMBODIMENT OF THE INVENTION Below, the structure of the side edge part of the floor body of the building material unit of this invention will be described with reference to an embodiment shown in the drawings.

FIG. 1 shows a vertical cross-sectional view of one embodiment of the structure of the present invention, in which 1 is the constituent main body of a floor body and a hollow steel column with an erected corner part thereof. This is a steel material made of H steel that constitutes the outer peripheral part of the floor body of a building unit, and in this invention, the steel material 1
A heat insulating material 2 is housed in a horizontally long horizontal recess shaped like the outer side of the heat insulating material 2, and the outside of the heat insulating material 2 is covered with a sheet 3.

To explain the embodiment in more detail, the heat insulating material 2 is made of a plate made of polyurethane or the like, which is highly flexible and highly resilient, and is bent and accommodated in the horizontal recess. The sheet 3 is made of a highly flexible and highly resilient plate such as a resin sheet (dam plate), and is fixed to the lower horizontal portion 1a of the steel material 1 with its lower edge being horizontal. , the lower horizontal part 1a is bent vertically from its tip and its upper edge is temporarily fixed to the upper horizontal part 1b of the steel material 1 with an adhesive tape 4. Incidentally, the heat insulating material 2 may be housed in a horizontal recess in a portion adjacent to the floor of another building material unit when constructing a building. Further, the heat insulating material 2 and the sheet 3 may be bonded together.

In addition, in FIG. 1, 5 is a floor material in the floor body of the building material unit, 6 is a resin sheet that constitutes the lower surface of the floor body and supports the heat insulating material 7, and in FIG. The hollow steel column erected in the figure is omitted.

The structure of the embodiment of the present invention constructed as described above is used as shown in FIG. In Fig. 2, the symbols with dashes added indicate each constituent member of the floor of another building unit, which differs from the floor in Fig. 1 in that the insulation material 2, sheet 3, and adhesive tape 4 are not present. It's different. When using the structure of the embodiment, after two building units are connected and installed adjacent to each other as shown in FIG. 2, the adhesive tape 4 is removed and the sheet 3
It is only necessary to release the temporary fixing at the upper edge, and by releasing the temporary fixing, the restoring force causes the sheet 3 to separate from the lower horizontal portion 1a of one steel material 1 to the lower horizontal portion 1' of the other steel material 1'. a, and using the stretched sheet 3 as a support, both steel materials 1, 1'
The restoring force causes the heat insulating material 2 to be provided between the floors of the building unit. After installing the heat insulating material 2 between the floor bodies in this way, the separately prepared floor material 8 is attached to the upper horizontal parts 1a, 1'a of the steel members 1, 1'.
Spread over time.

Note that the heat insulating material 2 can also be adhered to the sheet 3.

As described above, according to the structure of the side end portion of the floor body of the building material unit of the present invention, a heat insulating material is accommodated in the horizontal recessed portion of the outer periphery of the floor body, and the outside of the heat insulating material is covered with a sheet. For example, just by releasing the temporary fixing of the upper edge of the sheet as in the example, the insulation material can be placed between the floor bodies of adjacent building units, which significantly saves labor on site construction work. Effects such as being able to do the following can be achieved.
