After the foaming resin adhesive 4 is foamed and hardened, the holding jig 30 is removed, and then the floor panel 10 is laid on the first and second leg members 1 and 2.

[0007]

SUMMARY OF THE INVENTION The above-mentioned Japanese Patent Application Laid-Open No. 7-910 is disclosed.
The construction method described in Japanese Patent Publication No. 15 is to wait for the foaming resin adhesive to cure while adjusting the upward movement of the floor base panel caused by foaming of the foaming resin adhesive by some means, and to perform level adjustment. In comparison with the conventional method using mortar dumplings, there is an advantage that level adjustment can be performed reliably without skill.

However, the standard for level adjustment is only the joist when attached to one of the walls, and accurate level adjustment can be performed for one side edge position of the floor base panel attached to the wall. The other side edge of the floor base panel and the side edge in the direction intersecting the joist must be determined by the nut member of the level holder, and it is not easy to take an accurate level. For floor base panels that do not touch the wall, all side edges will be leveled by the level holder, and work will be difficult, and precise adjustment of the level holder will be required to ensure accuracy .

Further, since the order of arranging the floor base panels is limited to the direction in which the floor base panels are sequentially advanced from the joist, when the floor base panels are arranged on a floor slab having a large area, the degree of freedom of work is limited. The floor sub-panel construction work may affect the progress of other work in the building. further,
Except for the joist, the spacer function between the floor slab and the floor base panel is basically provided by a foaming resin adhesive such as urethane foam, and a large amount of foaming resin adhesive can be used. Because of the necessity, high construction costs are involved. In addition, since the amount of the foaming resin adhesive is large, the foaming pressure for moving the floor base panel upward during foaming increases, and a work of arranging a double drop or the like on the floor base panel in order to suppress the pressure. Is required.

[0010] The construction method described in Japanese Patent Application Laid-Open No. Hei 10-292602 greatly improves the above disadvantages in many respects. However, after leveling the left and right first leg members 1, 1 using foaming of the foamable resin adhesive 4, a plurality of second leg members 2 are connected to the entire length of the first leg member 1 in the meantime. Is also arranged along the level using foaming of the foamable resin adhesive 4, so that the amount of use of the foamable resin adhesive increases and it is not easy to reduce the construction cost. Jig 50 and holding jig 3
0 must be used. Further, before the floor panel 10 is laid, the first and second leg members 1 and 2 are arranged on the floor slab surface, and there is a restriction on the action at the time of laying the floor panel 10.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and the arrangement of a floor base panel on a floor slab surface is easy in terms of work, is low cost, and has a high level of accuracy. It is an object of the present invention to provide a method of constructing a new floor base panel and a floor structure produced by the method, which can be performed in a state in which the floor is secured.

[0012]

SUMMARY OF THE INVENTION According to the present invention, there is provided a method of constructing a floor panel according to the present invention, in which at least a first pair of side edges of a floor panel to be arranged is located. At the position on the floor slab surface, the elongated first leg member is level-fixed along the first side edge pair, and is fixed on the level-matched first leg member. A method of constructing a floor base panel in which a floor base panel is arranged such that a first side edge pair is placed thereon, wherein the floor base panel is a second base edge pair that is not the first side edge pair. Along the one side edge of the second leg member, the height of which is lower than the distance between the upper surface of the first leg member and the floor slab surface whose level has been adjusted, so that a part of the second leg member projects outward. Using an appropriate number of fixed floor base panels, the first floor base panel was adjusted to the level described above. After arranging the first pair of side edges so as to rest on the first leg member, a foamable resin adhesive is injected into a gap between the lower surface of the second leg member and the floor slab surface to form a foam. After curing, the positioning and fixing of the floor base panel are performed. Next, the second floor base panel is placed on the leveled first leg member with the first side edge pair placed thereon, and The other side edge of the second side edge pair is placed so as to be placed on a portion of the already-placed floor base panel that protrudes outside the second leg member, and the second sheet thus placed is placed. It is characterized in that foaming resin adhesive is injected into a gap between the lower surface of the second leg member of the floor base panel and the floor slab surface, and foam curing is sequentially repeated.

In the present invention, for example, 1800 mm ×
When a rectangular floor base panel such as 600 mm is used, preferably, its short side is the first side edge pair. Then, the long first leg members are level-adjusted and fixed to the floor slab surface so that the short side of each floor base panel can be placed thereon. The method of adjusting the level of the first leg member is arbitrary, but the level adjusting means includes:
A method in which a reference height line is radiated from the floor slab surface in all directions at a predetermined height by a floodlight, and the distance between the reference height line and the first leg member is measured by appropriate means is suitable. Yes, it is possible to take a level at any position regardless of the size of the floor slab surface.

[0014] Preferably, a mortar is provided between the back surface of the first leg member and the floor slab surface, and the mortar is hardened before the first mortar is used while utilizing the reference height line or the like.
The leg member is pressed against the mortar to deform the mortar, the first leg member is positioned at a predetermined height, and the mortar is hardened. Thereby, level adjustment and fixing of the first leg member are completed.

On the leveled first leg member,
The floor base panel is arranged so that the first side edge pair of the floor base panel is placed on the floor base panel. All of the floor base panels to be arranged are placed on the first leg member whose at least two opposing side edges are level-matched. Regardless of the size of the floor slab surface, the level of the floor base panel is Easily secured.

If the floor base panel is left as it is with two opposing side edges (first side edge pair) resting on the leveled first leg member, the floor base panel is lowered by its own weight. A convex sag occurs. To prevent it,
In the present invention, the height of the floor base panel is adjusted to the level along one side edge of the remaining two side edges (second side edge pair) other than the first side edge pair. A floor base panel is used in which a suitable number of second leg members, which are shorter than the distance between the upper surface of the first leg members and the floor slab surface, are fixed so that a part thereof protrudes outward.

The height of the second leg member is set to be lower than the distance between the upper surface of the leveled first leg member and the floor slab surface. This is because the surface of the slab has irregularities and absorbs the irregularities. As will be described later, a foamable resin adhesive is injected into a gap between the second leg member and the floor slab surface, and the foam is cured by foaming to fill the gap, thereby positioning and fixing the floor base panel. Is performed.

The second leg member is fixed so that a part thereof protrudes outward in order to support the opposing side edge of the adjacent floor base panel there. The fixing of the second leg member to the floor base panel may be performed by appropriate means such as nailing or screwing at the construction site. Further, the length of the second leg member is arbitrary provided that the second leg member can be fixed to the floor base panel and the adjacent floor base panel can be placed thereon. The number of attached members is also arbitrary. Any of them may be appropriately determined in consideration of strength, cost, and the like.

In the construction, the first floor base panel is placed on the leveled first leg member so that the first pair of side edges is placed thereon, and then the second floor base panel is placed on the second leg member as described above. A foaming resin adhesive is injected into a gap between the lower surface of the leg member and the floor slab surface, foamed and hardened, and the floor base panel is positioned and fixed. Only a small amount of foaming resin adhesive is injected into the gap, and the foaming pressure is small. Therefore, in a normal mode, it is not necessary to place a double drop or the like on the floor base panel when foaming and curing the foamable resin adhesive.

Rather, the floor base panel flexes downwardly convexly due to the gap generated between the second leg member and the floor slab surface,
It may be difficult to inject the foamable resin adhesive or hinder foaming of the injected foamable resin adhesive. Therefore, in a preferred embodiment according to the present invention, an appropriate level holder is used, and the level holder is interposed between the back surface of the floor base panel and the floor slab surface so as to prevent the downward convex deflection from occurring. . By using a variable height holder as the level holder, it is possible to appropriately cope with unevenness of the floor slab surface, and also used in the construction place of the floor base panel adjusted to other dimensions. It becomes possible. This level holder is removed at an appropriate time after the foaming of the foamable resin adhesive.

After the first floor base panel is positioned and fixed,
The second floor base panel adjacent thereto is arranged. At this time, the first pair of side edges of the second floor base panel is placed on the leveled first leg member, and
Of the pair of side edges (i.e., the side edge on which the second leg member is not fixed) protrudes outside the second leg member of the floor base panel already arranged. And place it on the part where it is. Then, as in the case of the first floor base panel, a foamable resin adhesive is injected into a gap between the lower surface of the second leg member and the floor slab surface, and foamed and hardened. Preferably, adjacent floor base panels are at least connected to the second floor base panel so that no floor noise is caused by rubbing of the floor base panels after the floor surface is formed.
Are arranged with a certain gap on the side opposite to the side edge.

Hereinafter, this procedure is repeated over the entire length of the first leg member. Similarly, the floor base panels are sequentially arranged in the side direction. After the placement or in the process of placement, the vicinity of the side edge of the floor base panel is fixed to the first leg member by appropriate means such as nailing or screwing, if necessary.
Thereby, the construction of the floor base panel according to the present invention is completed, and thereafter, a flooring structure according to the present invention is constructed by laying an appropriate flooring material on the floor base panel surface thus constructed.

In the present invention, there is no limitation on the shape and structure of the first and / or second leg members, and materials, plywood, particle board, and the like conventionally used as so-called joists in this type of floor construction. It may be a wood material such as MDF, or a laminate of the wood material and a resin material foam. Further, it is also effective to use a leg member in which a vibration damping material such as nonwoven fabric or rubber is laminated on the surface of a wooden material including plywood.

In the present invention, the term “floor slab” includes not only a concrete slab made of reinforced concrete by a conventional method, but also a concrete slab made of precast concrete, a floor panel made of cellular concrete panels, and the like. The term “floor base panel” is used in ordinary floor construction to include all of the above-mentioned “floor slab” directly or via a joist. It may be a flat material such as plywood, or a composite material in which a foamed resin material is adhered to the back side of plywood.

[0025]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a diagram for explaining a method of constructing a floor base panel according to the present invention in the order of steps.
FIG. 4 is a plan view illustrating a state after floor construction. FIG. 3 is a perspective view showing a floor base panel, and FIG. 4 is a perspective view showing a level holder. FIG. 5 is a plan view showing a state in which the method of constructing a floor base panel according to the present invention is being performed on a floor slab surface.

In this embodiment, the floor base panel 10
Is a rectangular material of 1800 mm × 600 mm made of wood such as plywood, particle board, and MDF.
The first leg member 1 is fixed at the position of the floor slab surface C where the a side (the first side edge side) is located (of course,
Depending on circumstances, the first leg member 1 may be fixed along the long side.) The first leg member 1 has a width of 50 mm
In this example, the laminate is made of a wood material 1a such as plywood and a resin foam 1b, but may be a single wood material. Further, a vibration damping material such as a nonwoven fabric may be laminated on the surface of the wooden material 1a.

First, an adhesive is linearly applied to the floor slab surface C where the left and right short sides 10a, 10a of the floor base panel 10 are to be located.
Are placed in a straight line (FIG. 1a). In this example, 2
The mortar lines 3, 3 are spaced at approximately 1800 mm. Mortar dumplings may be placed at predetermined intervals. Next, an adhesive is applied to the back surface of the first leg member 1 and placed on the mortar 3. Then, the first leg member 1 is pushed down so that the surface height position is along the reference line.
The mortar is easily deformed and the level of the first leg member 1 is easily adjusted to a predetermined height position. After curing, the mortar is cured.

The left and right short sides 10a, 10a of the floor base panel 10 shown in FIG. Is fixed to the leg members 1, 1 with nails or screws (FIG. 1).
b). As shown in the drawing, the floor base panel 10 has a second leg member 2 having a length of about 300 mm and a width of about 100 mm on one long side 10b1 side of a pair of long sides (a second pair of side edges). With about half of the length protruding outside,
A plurality (three in this example) are fixed at predetermined intervals by screws 5, and nothing is attached to the other long side 10b2. Similarly to the first leg member 1, the second leg member 2 is a laminate of a wood material 2a and a resin foam 2b such as plywood, but may be configured by a single wood material. Also,
Similarly, a vibration damping material such as a nonwoven fabric may be laminated on the surface of the wooden material 2a. In the illustrated example, the thickness (height) is the same as that of the first leg member 1, but the height may be somewhat reduced.

When the floor base panel 10 is arranged by using the first leg members 1, 1, as shown in FIG.
A gap is formed between the back surface of the second leg member 2 of the floor base panel 10 and the floor slab surface C by the thickness of the floor base panel 10, and the floor base panel 1
In the case of 0, there is a possibility that the sheet sags downward due to its own weight. To prevent this, a level holder 5 shown in FIG. 4 is used. The level holder 5 includes a base 6, a screw rod 7 screwed to the base 6, and a support plate 8 attached to a tip of the screw rod 7. By turning the screw rod 7, the height of the support plate 8 can be adjusted. After substantially adjusting the height to a predetermined height (that is, the distance between the surface of the first leg member 1 and the floor slab surface C), insert it between the back surface of the floor base panel 10 and the floor slab surface C (FIG. 1d). . Thereafter, readjustment is performed according to the unevenness of the floor slab surface C, and the level adjustment of the entire floor base panel 10 is performed.

Thus, the floor base panel 10 is held in a state where a gap S corresponding to the thickness of the mortar 3 is formed between the lower surface of the second leg member 2 and the floor slab surface C. A foamable resin adhesive solution 4 made of, for example, a one-component foamable urethane resin is injected into the gap S to wait for foaming and hardening. After foaming and hardening, the level holder 5 that has been inserted is removed. The mounting of the ground panel 10 is completed (FIG. 1e). In addition, as the foamable urethane resin solution, the one-component urethane resin is preferably used,
In addition to a two-part urethane resin, a foamable phenol resin or the like which is made of a phenol resin as a main raw material and is foam-cured by adding a foaming agent and a curing agent can also be used.

Next, mounting of the second floor base panel 10-2 and thereafter is sequentially performed. As shown in FIG.
In mounting the second floor base panel 10-2, the first pair of side edges (short sides 10a, 10a) is placed on the leveled first leg members 1, 1, and The long side 10b2 of the second pair of side edges (long side 10b1, 10b2) to which nothing is attached is protruded outside the second leg member 2 of the floor base panel 10 on which the already disposed long side 10b2 is already disposed. On the part where it is. After that, as in the case of the first floor base panel 10, the entire level is obtained by using the level holder 5, and then the second leg member 2 of the second floor base panel 10-2 is arranged. In the same manner, a foamable resin adhesive is injected into the gap S between the lower surface and the floor slab surface C and foamed and hardened. Hereinafter, similarly, the third floor base panel 10-3, the fourth floor base panel 10-4,... In addition, they will be spread horizontally. At this time, a space of about 5 mm is provided between the floor base panels and the floor base panels are spread. Thereby, floor noise after floor construction can be prevented.

In the method of constructing a floor base panel according to the present invention, as shown in FIG. 5, the first leg member 1 can be moved not only along the floor of the floor slab but also on the floor according to the direction and position of the floor base panel. It is also fixed to the inside of the slab both vertically and horizontally. However, when the floor base panel is attached, only the first leg member 1 exists on the floor slab surface, and there are many spaces in which the worker can move freely. Therefore, the work of installing the floor base panel becomes extremely easy. In addition, the amount of the foaming resin adhesive required for fixing the second leg member 2 is small, so that the cost is reduced and the floor base panel 10 warps without being pressed down by double hanging or the like. Because nothing happens, the work is simplified.

The floor substrate 10 laid as described above
By laying, for example, a flooring material (not shown) as a floor finishing material, a floor structure of the building is completed. Since all the flooring materials 10 are leveled and leveled, it is possible to reliably lay a conventionally known flooring material by nailing or sticking with an adhesive.

Although the above description has been made by taking as an example the case where floor base panels are arranged on a concrete slab, the construction method of the present invention is similarly applied to the floor base of a wooden detached house. Can be. In this case, a thin tatami mat can be used as the flooring material. Further, although not shown, in addition to a plywood or a laminate of a foamed resin material on the back surface of the plywood, a wood base material (natural material, plywood, Particle boards or the like may be buried at predetermined intervals.

[0035]

According to the present invention, the arrangement of the floor base panel on the floor slab surface can be easily performed at a low cost.
In addition, it is possible to perform the adjustment in a state where a high-accuracy level adjustment is secured.
