BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor construction method for a detached house, and more particularly to a method for constructing a first-floor floor of a detached house using unit support legs whose floor level can be easily adjusted. .

[0002]

2. Description of the Related Art Conventionally, as a typical construction method for constructing a first-floor floor of a detached house, as shown in FIG. 20 and FIG. The upper and lower through holes of the base 102 are fitted into bolts (not shown), the base 102 is arranged on the base 101 along its longitudinal direction, and the large pull 103 is provided between the opposing bases 101.
A method is employed in which the Daihiki 103 is supported by a wooden bundle 105 erected on an independent foundation (or a pile of stones) 104 installed on the soil A (soil). The joist 106 is fixed on the base 102 thus mounted on the foundation 101, and the joists 107 are fixed by nailing or the like at predetermined intervals on the haul 103 which is laid on the foundation 101. However, the base material 108 is laid on it. Recently, concrete is also placed in the soil. In this case, as shown in FIG. 22, the bundle 105 is erected directly on the concrete slab 109 to support the large pull 103.

[0003]

In any of the above-mentioned conventional methods, as shown in FIG. 23, it is necessary to concretely lay a planar base 101 corresponding to the partition of each room. As a result, it takes a long time to construct the foundation, and the amount of concrete increases, especially when placing concrete in the soil as in the recent construction method, prolonging the construction period and increasing costs are major issues. There is. In addition, since the level adjustment of Daihiki is performed while cutting the height of the bundle at the construction site, it requires skill to adjust the level, and the construction is a complicated and time-consuming process. . In addition, although the bundles, Daihiki, joists, and base materials are all made of wood, the problems of the recent decrease in forest resources and the environmental destruction caused by logging are greatly highlighted, and the amount of timber used should be minimized. It is desired to reduce it. Furthermore, in the conventional floor construction method, since the foundation is concrete-cast into a flat shape corresponding to the partition of each room, the partition is fixed and the partition can be freely removed or moved. There is a difficulty that you cannot do it. In addition, since the floor structure has a large number of contact portions between timbers, floor squealing is likely to occur, which is also one of the problems to be solved by the conventional method.

The present invention has been made in view of the problems of the conventional floor construction method for a detached house as described above. The amount of wood used is small, and the floor level can be easily adjusted. The purpose of the present invention is to provide a floor construction method for a detached house that is easy to construct and can be performed in a short period of time and at low cost. A further object of the present invention is to provide a floor construction method for a detached house in which the partition can be freely installed, the partition can be removed and moved freely, and there is almost no problem such as floor ringing. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS While explaining the embodiments shown in the accompanying drawings,
The present invention will be specifically described. FIG. 1 shows an embodiment of floor construction of a detached house according to the present invention, in which a foundation 2 is formed along the longitudinal direction on the upper end surface of a concrete-cast foundation 1 as in the conventional case. The unit support legs 20 are arranged on the concrete slab 10 at a predetermined pitch. Of the floor panels 40, the floor panel arranged along the foundation 1 has its one edge placed on the base 2 of the foundation 1 and the other edge supported by the unit support leg 20. It is arranged. Further, the floor panel 40 arranged above the concrete slab 10 between the dirt is arranged so that the edge portion thereof is supported by the unit supporting legs 20. In addition, in another aspect, as shown in FIG. 3, between the foundation 1 and the base 2 (or the joist 3 shown in FIG. 9), moisture-proof property is provided at a predetermined interval in the longitudinal direction of the foundation. The sheet-like packing 4 can be interposed. With this configuration, direct contact between the foundation 1 and the base 2 (or the joist 3) is blocked, and the gap 5 between the packings 4 acts as a ventilation hole. Moisture is prevented from being directly transmitted to the wood material.

The floor construction of this embodiment will be described below in the order of steps. First, as shown in FIG. 2, a concrete slab 10 is formed by concrete-casting the foundation 1 in a frame shape corresponding to the outer shape of the house and also concrete-casting the soil surrounded by the foundation 1. The concrete pouring between the foundation and the soil is the same as the conventional one, but in the present invention, since the floor panel is laid using the unit supporting legs, the construction shown in FIG.
Unlike the conventional construction method shown in Fig. 3, it is not necessary to form the foundation at the position corresponding to the partition installation place in each room, therefore the workability of the foundation can be improved and the construction period can be shortened and the concrete usage amount can be increased. Also decreases. As described above, the upper end surface of the foundation 1 may be, if necessary, as shown in FIG.
As shown in, the moisture-proof sheet-like packing 4 such as a polyvinyl chloride sheet can be arranged at predetermined intervals in the longitudinal direction. This sheet-like packing 4 blocks direct contact between the foundation 1 and the base 2, and the gap 5 between the packings 4 acts as a ventilation hole, so that the moisture from the concrete of the foundation 1 directly reaches the base 2. It is prevented from being transmitted and exhibits a moisture-proof function.

Thereafter, as shown in FIG. 1, the unit support legs 20 are arranged on the concrete slab 10 in the soil at a predetermined pitch, and the floor panel 40 is laid. At this time, if necessary, the floor-contacting base 21 of the unit support leg 20 can be fixed to the concrete slab 10 by using an adhesive. As shown in FIG. 4, the unit support leg 20 includes an anti-vibration floor-contact base 21 made of an elastic material such as rubber, and the base 2

The amount of wood used can be greatly reduced in combination with the omission of large hauls or even the omission of joists or even omission of joists. Furthermore, since concrete is also placed in the soil, the amount of concrete used will increase compared to the case where concrete is not placed in the conventional soil, but since the foundation can be formed in a frame shape corresponding to the outer shape of the house, The amount of concrete used is reduced and the workability is improved, and the workability is greatly shortened in combination with the improvement of workability by using the unit support legs, and the amount of wood used is also reduced as described above. As a result, the cost can be considerably reduced. Also, since each unit support leg has sufficient strength to support the load of the floor and partition, it is possible to freely install the partition at a location corresponding to the installation location of each unit support leg, and also to remove and move the partition freely. It can be carried out. Furthermore, since there are few points of contact between the timbers, the floor squeal can be significantly reduced.
