Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor construction method capable of extremely easily constructing a floor structure in which a floor joist is supported while being leveled by an auxiliary bundle. More specifically, even when a heat insulating material such as urethane is sprayed over the floor surface over a predetermined width from near the wall, it is extremely easy to perform a floor structure in which the floor joists are supported by an auxiliary bundle on the floor surface. The present invention relates to a floor construction method that can be configured by.

[0002]

2. Description of the Related Art As a floor construction method in a reinforced concrete apartment house, etc., a reinforced concrete wall is attached with a leveled joist in a leveled state, and a large pull is laid over the grooved joist. Put a floor board or a waste board such as a concrete panel,
It is known to lay a floor finish on this. In such a floor construction method, horizontal members such as joists and large pulls are supported at a predetermined height position on the floor in a leveled state. Set up an auxiliary bundle between
Each auxiliary bundle is fixed to the horizontal member and the floor.

[0003] Here, the distance between the cross members, for example, the joists and the floor surface, varies depending on the location, and if the auxiliary bundle is cut in accordance with the distance each time, the working efficiency is extremely poor. Therefore, a method is used in which an auxiliary bundle having a certain length is prepared and a wedge material or a gap adjusting plate having a predetermined thickness is inserted between the auxiliary bundle and the joists to adjust the gap.

[0004]

However, in the method using the wedge material and the space adjusting plate, although the auxiliary bundle can be made to have a standard size, it is necessary to prepare the wedge material and the space adjusting plate, and the wedge material In this case, it is necessary to adjust the insertion amount to adjust the gap, and in the case of the gap adjusting plate, it is necessary to select or manufacture a gap adjusting plate having an appropriate thickness.

Further, in the case of a floor structure having a low floor height, it may be inconvenient because there may not be enough room to insert a wedge material or a space adjusting plate.

Furthermore, according to the recently established quality standard law, each item such as heat insulating airtightness and sound insulation is specified as the performance of the floor, and the inner wall surface of the outer wall is insulated with urethane or the like. In addition to spraying the material, it is also obliged to spray the heat insulating material on the ceiling surface and the floor surface in contact with the wall surface in a range of a predetermined dimension width (600 mm) from the wall side. In this case, in the operation of raising the auxiliary bundle for supporting the joists on the floor surface, it is necessary to raise the auxiliary bundle on the floor portion where the heat insulating material is sprayed.

When the auxiliary bundle is set up on the heat insulating material, the auxiliary bundle is sunk due to the crushing of the heat insulating material, so that it is not possible to horizontally support the groin joists. Therefore, when forming an auxiliary bundle on the floor portion where the heat insulating material is sprayed, the heat insulating material is scraped off from the floor portion by the area required for forming the auxiliary bundle, and the floor portion is exposed. Later, it is necessary to build an auxiliary bundle on it. However, since it is necessary to scrape the heat insulating material every time the auxiliary bundle is set up, the efficiency of the stacking operation is significantly reduced.

The object of the present invention is to solve the above problems.
We propose a floor construction method that can support leveled floor joists with an auxiliary bundle without using a wedge material or space adjustment plate, or scraping the heat insulating material from the floor surface. To do.

BEST MODE FOR CARRYING OUT THE INVENTION An example of a floor construction method to which the present invention is applied will be described below with reference to the drawings. The floor construction method described below is for constructing a wooden floor set on a floor surface made of reinforced concrete.

First, as shown in FIGS. 1 (a) and 1 (b),
A heat insulating material 11 such as urethane resin is sprayed to a wall surface 1 made of reinforced concrete with a predetermined thickness, and a wall plate 12 is stretched on the surface side. The heat insulating material 11 is not limited to the wall surface 1, but has a predetermined width from the wall (generally 600 mm).
It is also sprayed on the floor surface 7 of. Further, a heat insulating material is sprayed on a ceiling surface (not shown) within a predetermined width from the wall side.

In this state, marking is performed on the surface of the wall plate 12, and rectangular temporary receiving plates 2 made of an elastic material are hot-melt bonded at regular intervals along the marking position (scoring line 1a). It is adhesively fixed to the surface of the wallboard using a chemical.

After that, as shown in FIG. 2, a grooving joist 3 having a rectangular cross section is placed on the side surface 2a of the temporary receiving plate 2 which is adhesively fixed to the wall surface 1, and the hot melt adhesive is also used. The perforated timber material 3 is temporarily fixed to the upper surface 2a of each temporary receiving plate 2. Here, the perforated timber material 3 is placed at a position separated from the wall surface 2 by a certain distance.

After this, an auxiliary bundle having the structure shown in FIG. 3 is manufactured. This auxiliary bundle 6 is a bundle material 4 having a rectangular cross section of a certain length.
An elastic rubber plate 5 having a rectangular shape which is slightly larger than the rectangular shape and having a certain thickness is adhered and fixed to the lower surface 4a of the elastic member by a hot-melt adhesive. The lower surface 5a of the elastic rubber plate 5 has a rectangular shape slightly larger than the rectangular shape. The bundle supporting member 60 of No. 1 is adhered and fixed by a hot melt adhesive. The bundle supporting member 60 includes a head portion 61 made of a rectangular steel plate and a leg portion 62 extending vertically from the lower surface 61b. In this example, a rectangular plate portion formed by cutting two notches into a rectangular steel plate is bent vertically downward,
Legs 62 are formed.

The auxiliary bundle 6 having this structure may be produced in a factory and brought to the construction site, or the bundle material 4, the elastic rubber plate 5 and the bundle support member 60 may be prepared on site and hot-melt bonded at the site. It may be manufactured by adhesive bonding using a chemical or the like.

Next, as shown in FIG. 4, each auxiliary bundle 6 is
They are arranged at regular intervals along the tentatively fastened timber joists 3. That is, the thin leg portion 62 made of a steel plate in the bundle supporting member 60 of the auxiliary bundle 6 is pierced into the heat insulating material 11 and the lower end 62a thereof is brought into contact with the floor surface 7, and thereafter,
The side surface of the auxiliary bundle 6, that is, the side surface 4b of the bundle 4 is adhered and fixed to the side surface 3b of the perforated joist 3 which it faces with a hot melt adhesive.

Here, since the floor surface 7 is mostly uneven, the spacing between the floor joists 3 and the floor surface portions where the auxiliary bundles 6 are erected vary. For this reason, the upper end portion (bundle material 4) of each auxiliary bundle 6 has a different amount L of protrusion from the upper surface 3c of the perforated joist 3 (FIG. 4 (b)).
reference).

In this example, the protruding portion 4c of each auxiliary bundle 6 is
The upper surfaces 3c of the joist 3 are aligned and cut with a cutting tool (not shown) so that the upper surfaces 4d and 3c are flush with each other. FIG. 5 shows the protruding portion 4c of each auxiliary bundle 6.
The state after cutting is shown.

After that, after removing the temporary receiving plate 2 from the wall surface 1 as shown in FIG. 6, as shown in FIG. The pulling material 8 is bridged, and the auxiliary bundle 6B having a structure similar to the auxiliary bundle 6 is also fixed to each large pulling material 8 in the same manner as described above. The auxiliary bundle 6B includes a bundle 4B and an elastic plate 5B adhered and fixed to the lower surface of the elastic plate 5B with a hot melt adhesive or the like. The lower surface of the elastic plate 5B is adhered and fixed to the floor surface 7 with the hot melt adhesive or the like. It Further, the side surface of the bundle 4B is adhesively fixed to the side surface of the pulling material 8, and the upper end portion thereof is
The part protruding so as to coincide with the upper surface of the large pulling member 8 is cut. Thereafter, a floor base panel such as a particle board is laid on the floor, and a floor finishing material is laid on the floor base panel to form a floor.

As described above, according to the floor construction method of this example, the auxiliary bundle 6 is not inserted between the floor surface 7 and the horizontal bridge members (kaki joist 3, large pulling member 8), but laterally. It is fixed to the side surface of the frame, and the part protruding from the upper surface is cut. Therefore, according to this example, the work of inserting the auxiliary bundle between the floor surface and the horizontal member is unnecessary, and a wedge member or a space adjusting plate for adjusting the interval is provided between the auxiliary bundle and the horizontal member. No need to plug in. Therefore, the bundling work can be performed extremely easily and quickly.

Further, since the upper surface of each auxiliary bundle 6 is flush with the upper surface of the horizontal member, the floor load directly acts on the auxiliary bundle as a compressive force. Therefore, the supporting strength of the floor can be made sufficient.

Further, in the construction method of this embodiment, the leg portion 62 of the bundle supporting member 60 constituting the lower end portion of the auxiliary bundle 6 is formed of a thin steel plate, so that it is sprayed onto the floor surface 7. It can be easily inserted into the heat insulating material 11, and its lower end 62a can be brought into direct contact with the floor surface 7. Therefore, it is possible to avoid sinking of the auxiliary bundle due to crushing of the heat insulating material, which would occur when the auxiliary bundle is erected with the heat insulating material sandwiched, and it is possible to reliably support the crease joists 3 in a horizontal state. Further, when the auxiliary bundle 6 is set up, the heat insulating material 1 is applied from the floor surface.
Since the work of scraping 1 is unnecessary, the bundling work can be performed efficiently and easily.

Further, in the construction method of this embodiment, the members are bonded and fixed using the hot melt adhesive, so that the member can be fixed easily and quickly.

In addition to this, in this example, the floor joists 3 are separated from the wall surface, and the lower end portion of the auxiliary bundle is an elastic rubber plate, so that a floor structure excellent in sound insulation and sound insulation is realized. You can

(Other Embodiments) In the above example, it is assumed that the bundle material and the horizontal material of the auxiliary bundle are wood, but the construction method of the present invention is not limited to materials other than wood ( It can also be applied to floor construction methods consisting of bundles of metal, plastic, etc. and horizontal materials. For example, when it is applied to the construction of a steel floor, the steel bundle and the steel horizontal member may be fixed by a method such as welding.

Further, the auxiliary bundle is not limited to the above example, but various structures can be used. For example, an auxiliary bundle 6A as shown in FIG. 8 can be used. The auxiliary bundle 6A has a bundle support member 60A composed of a rectangular steel plate 61A and a small-diameter steel bolt or bar steel 62A extending vertically from the center of the rear surface thereof.
Bolt or steel bar 62A is welded to steel plate 61A
It should be fixed to. In any case, the auxiliary bundle may have any shape as long as it can easily form a state in which the lower end portion of the auxiliary bundle penetrates the heat insulating material and is in direct contact with the floor surface. Therefore, in order to inexpensively manufacture the bundle supporting member having such a configuration, for example, it is desirable that the bundle supporting member is a resin molded product.

Next, in the above example, the groin joists are placed on the temporary receiving plate 2, but instead of using the temporary receiving plate 2, a temporary receiving pad made of an elastic material can be used.

In this case, as shown in FIG. 9, the temporary receiving pad 2A is attached to the surface of the wall board along the marking position by using a hot melt adhesive or the like, and then the temporary receiving pad 2 is attached.
The side surface 3a of the joist is attached to the vertical surface 200 of A using a hot melt adhesive or the like. The subsequent work is the same as when the temporary receiving plate 2 is used.

[0036]

As described above, in the floor construction method of the present invention, the auxiliary bundle is fixed to the side surface of the kerf and projected from the upper surface of the kerf instead of being inserted between the kerf and the floor surface. A floor set is constructed by cutting the part.
Therefore, the bundling can be performed by a simpler work than the work of inserting the auxiliary bundle. Further, since a wedge material for adjusting the spacing, which is required when inserting the auxiliary bundle into the gap having variations, is not required, and the inserting work is also unnecessary, so that the floor can be constructed by an extremely simple operation.

Further, in the present invention, as the auxiliary bundle, one having a structure in which the lower end portion of the auxiliary bundle can be easily pierced into the heat insulating material sprayed on the floor surface so that the lower end directly contacts the floor surface is used. . Therefore, it is possible to avoid the adverse effect that the auxiliary bundle is bundled while the heat insulating material is sandwiched between the auxiliary bundle and the floor surface, and the auxiliary bundle is sunk due to the crush of the heat insulating material, so that it becomes impossible to horizontally support the creased joists. Furthermore, since the work of scraping off the heat insulating material in the portion where the auxiliary bundle is to be set up becomes unnecessary, the bundling work can be performed easily and efficiently.

In addition to this, in the present invention, since the auxiliary bundle is adhesively fixed to the horizontal member and the floor surface using the hot melt adhesive, the auxiliary bundle can be fixed easily and quickly. It is possible.

Further, in the floor construction method of the present invention, since the groin joists are placed away from the wall surface and the auxiliary bundle is fixed to the floor surface via the elastic rubber plate, the sound insulation and the soundproofing are achieved. It is possible to realize a floor with extremely excellent properties.
