Description

  The present invention relates to a method for constructing a floor structure.

Conventionally, as shown in FIG. 7, a floor structure in an apartment house is constructed by placing a floor base material 19 made of foam plastics in close contact with an upper surface of a concrete slab 17 through a non-land adjuster 18 such as mortar. Has been. In order to install the floor base material 19 on the concrete slab 17 in which the pipe 20 is installed, the bottom surface of the floor base material 19 is cut out. As another floor structure, for example, the invention of Japanese Patent Application Laid-Open No. 2006-45887 is known.
JP 2006-45887 A

  However, in the above floor structure, the bottom surface was notched at the site in order to install the floor base material on the concrete slab where the piping was installed. There was a problem that it took time to install.

  This invention is made | formed in view of these problems, The objective is to provide the construction method of the floor structure which is technically easy and can install a floor base material easily.

  A construction method of a floor structure for solving the above problems is a covering body comprising an upper plate having an appropriate width so as to cover a pipe on the upper surface of a concrete slab, and support legs installed at appropriate intervals on the lower surface of the upper plate. After installing, a thin floor base material is installed on the upper surface of the covering through a non-land surface adjusting material, and the other floor base material is placed on the upper surface of the concrete slab by bringing it into close contact with both sides of the thin floor base material. It is characterized by being installed via land control materials. Further, the covering includes that it is installed on the lower surface of a thin floor base material.

  Construction efficiency is improved because the bottom surface of the floor base material is not cut out. In addition, the pit specification with only the piping installation part being made independent and the level taking into account the thickness of the floor base material to be installed on the upper part can be taken out, so that the floor base material can be directly applied to the upper part of the covering. Moreover, since the covering is installed on the lower surface of the thin floor base material, the floor base material can be installed in the piping section simply by installing the thin floor base material on the pipe, so that the construction can be simplified.

  Hereinafter, an embodiment of a method for constructing a floor structure according to the present invention will be described with reference to FIGS. This floor structure is in an apartment house, and is constructed by laying a floor base material made of foamed plastics closely on the upper surface of a concrete slab with a non-land surface adjusting material such as mortar.

  First, as shown in FIG. 1, a joist 4 for level adjustment is installed with a bundle 5 on a wall surface 3 of a concrete slab 2 on which a pipe 1 such as a drain pipe is constructed. Next, as shown in FIG. 2, a covering 6 is installed on the pipe portion of the concrete slab 2 to cover the pipe 1.

  As shown in FIG. 3, the covering 6 includes a planar rectangular upper plate 7 such as a plywood, and support legs 8 installed at appropriate intervals on the lower surface of the upper plate 7. The connecting member 9 is installed on the upper plate 7 and the upper plate 7 is joined to the connecting member 9. Therefore, when this covering 6 is installed so as to straddle the pipe 1 (so that the support legs 8 are located on both sides of the pipe 1), the pipe 1 is covered and protected by the upper plate 7. The covering 6 is also installed on the upper surface of the concrete slab 2 via the unevenness adjusting material 10a below the support leg 8, and the unevenness is adjusted by the unevenness adjusting material 10a. The unevenness adjusting material 10a is obtained by soaking an adhesive in a sponge. After adjusting the unevenness with the sponge and taking a level, the adhesive is solidified and fixed. Since the unevenness adjusting material 10a is a sponge, adjustment is easy and can be performed any number of times. The connecting member 9 of the covering 6 can be installed not on the inside of the support leg 8 but on the outside.

  Next, as shown in FIG. 4, a thin floor base material 11 is placed on the upper surface of the covering 6 and bonded with an adhesive or the like. Then, another floor base material 12 is installed on the concrete slab 2 on both sides of the thin floor base material 11 via the unevenness adjusting material 10 so as to be in close contact with the thin floor base material 11 and the level adjustment is performed by the joist 4. .

  The floor base materials 11 and 12 are foamed resin composites, a lower member 13 made of a foamed resin such as a polystyrene resin, a polyleophine resin, and a urethane resin, and a hard heat installed on the upper surface of the lower member 13. It is comprised from the crosspiece (not shown) of the plastic foam resin.

  Next, when the floor structure 15 is constructed by laying the finishing plate 14 on the upper surfaces of the floor base materials 11 and 12 whose levels have been adjusted, the floor base materials 11 and 12 even if the concrete slab 2 is provided with the pipe 1. Can be installed easily.

  FIG. 6 shows a covering body 16 according to another embodiment, in which the covering body 16 is integrally bonded to the lower surface of the thin floor base material 11. When the covering 16 is integrally bonded to the thin floor base material 11 as described above, the floor base material 11 is also installed at the same time as the covering 16 is installed, so that efficient construction can be performed.
