Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a floor structure for a house that can increase the in-plane rigidity of the entire floor surface and improve the efficiency of its construction work.

[Conventional technology]

In recent years, for example, as shown in Fig. 5, a floor surface S is formed by passing a plurality of concrete floor panels a between the floor beams and b that form the bridge of a house. Panel construction methods are widely used.

In addition, in such a construction method, since the floor beams S and B are placed independently, the floor surface S tends to bend significantly due to the applied load, as shown by the dashed line in the same figure. The in-plane rigidity of the entire floor surface has been improved by connecting the floor beams S and B with places C...- to increase the strength of the beam materials.

[Problem to be solved by the invention]

However, with this method, it is not possible to suppress the deflection of the floor panel a itself, and it takes time and effort to connect the place C. In addition, the connected place C requires installation work for water pipes, etc. placed below the floor surface. This will lead to a significant decline in overall workability, such as loss of efficiency.

The present invention is based on the use of reinforcing bars placed between adjacent floor panels and plate materials that are integrally fixed across the upper surfaces of the reinforcing bars, so that the floor panels can be firmly and integrally connected. The object of the present invention is to provide a floor structure for a house that can solve the above-mentioned problems.

[Means to solve the problem]

In order to achieve the above object, the floor structure of the house of the present invention has the following features:
A floor panel made of lightweight concrete and having a notch at the side end is installed between the floor beams with the notch above and adjacent to each other, thereby forming a recess with an open top by the adjacent notch, and A reinforcing bar supported by the floor beam is arranged, and the recess is filled with mortar and solidified, while a plate material on the upper surface of the floor panel and spanning the floor panel is integrated with the floor panel. House floor structure.

[Effect]

In this way, the floor structure of a house can firmly connect the floor panels and the floor beams by reinforcing bars supported by the floor beams and embedded in the mortar, and can increase the rigidity of the floor panels in the direction between the beams. Moreover, since each floor panel is integrated by the plate material spanning between its upper surfaces, the in-plane rigidity of the entire floor surface can be greatly improved as well as the rigidity of the reinforcing bars and the plate material.

Furthermore, since this method eliminates the use of conventional places, it does not interfere with piping work, etc. (it is possible to greatly improve the overall construction efficiency).

〔Example〕

In the figure, the floor structure of the house includes a flooring material 5 that spans between the floor panels 3.3 and is integrated with the floor panels 3 on the top surface of the floor panels 3 installed between the floor beams 2.2. It is attached,
Further, reinforcing bars 9 supported by the floor beams 2 and buried in the mortar M are disposed in the recesses 6 formed between the adjacent floor panels 3.3.

The floor beam 2 is a beam member that supports the upper floor of a house,
In this example, there are upper and lower flanges 12 on the upper and lower ends of the nib 11.
13, and are supported horizontally, parallel to each other and at the same height, for example, by pillars of a house. Further, a metal fitting 14 for supporting the wall panel P is attached to the floor beam 2A located on the outer wall side of the house.

In this example, the bracket 14 is the vertical piece 1 along the back of the wall panel P.
An L-shaped part 15 is provided on the lower edge of the panel 5A from which a receiving piece 15B that faces outward and supports the lower end of the wall panel P is protruded, and a lower part of a U-shaped base part 16, for example, is integrally fixed to the back surface of the L-shaped part 15. By welding to the upper flange 12, it is firmly fixed to the floor beam 2A.

Furthermore, floor panels 3 are constructed between each floor beam 2.2.

The floor panel 3 is made of aluminum pieces in cement paste, for example.
The frame is provided with an oblong rectangular base body 19 made of lightweight concrete mixed with lightweight aggregate such as pumice, and in this example, the short side thereof is placed on the upper flange 12 of the floor beam 2, and the frame is passed over.

Therefore, the frame is passed between the pair of floor beams 2.2 and the floor panel 3-
... are arranged in a line with their long side ends 19A abutting each other to form a vertical line forming a part of the floor surface S. Note that the floor panels 3 constituting this vertical row and the floor panels 3 constituting other vertical rows that are similarly installed adjacent to the sides of the vertical row are arranged in a row with their short side edges 19B facing each other. Forming rows R that are juxtaposed.

Further, as shown in FIG. 4, the floor panel 3 has a notch 20 at the long side end 19A of the base body 19 by cutting out the upper part thereof, so that the floor panels 3 are arranged vertically. In between, a recess 6 which is closed at the bottom and open at the top is formed by adjacent notches 20.20 by abutting the respective side ends 19A, 19A against each other. In addition, reinforcing bars 9 are provided in the recess 6.
will be arranged.

The reinforcing bars 9 are made of straight rods, and in this example, extend from the upper surface of the upper flange 12 of the floor beam 2 to the approximate center thereof and each recess 6.
A vertical piece 21 that rises along the side edge 19B at a position facing the
It is supported by the floor beam 2 by being inserted into the through hole 22 of the floor beam 2.

The reinforcing bar 9 has protruding parts 9A, 9A protruding from the front upright piece 21 on both sides with a length of 1 to 4 times the width of the floor panel 3 or more, respectively, formed in vertical rows, and recesses facing each other in a straight line. 6 and is embedded in mortar M that fills the recess 6 and hardens.

Therefore, the reinforcing bars 9 can firmly connect each floor panel 3 and the floor beam 2, and can improve the longitudinal rigidity of the floor panel 3. The mortar M is also filled in the gap DI between the vertical lines and the gap D2 between the vertical lines and the outer wall panel P.

A plate material 5 is attached to the upper surface of the floor panel 3 connected to the floor beam 2 by such reinforcing bars 9 over the entire surface thereof.

In this example, the board material 5 is a high-strength particle board made by heat-pressing wood chips or the like with a binder, and is laid across each floor panel 3, and is also fitted with screw fittings, nail fittings, etc. It is integrated with each floor panel 3 by being fixed to each floor panel 3 using fixing fittings 25 such as pin fittings and an adhesive.

Although the plate material 5 is formed of a single, wide-sided plate, the rigidity of the floor surface is further increased by its in-plane rigidity, but it can also be formed using a plurality of plate pieces.

〔Effect of the invention〕

The floor structure of the house of the present invention, like a ridge, has reinforcing bars supported by the floor joists and embedded in mortar in the recesses between the floor panels installed between the floor joists, so that each floor panel The floor panel can be firmly fixed to the floor beam, and the rigidity of the floor panel in the direction between the beams can be increased. Further, the floor panels can be integrally and firmly connected by the plate material attached across the upper surfaces thereof, and together with the reinforcing bars and the plate material, the rigidity of the floor surface can be greatly improved.

Furthermore, since this method eliminates the use of conventional places, water pipe work can be easily carried out and construction efficiency can be greatly improved.
