Abstract

PURPOSE:To easily construct a floor part out of a small number of members by welding a flat steel material to the upper surface of each end of a long steel material, by putting a part protruded from the both ends of the steel material, on the upper part of a foundation, and by putting a floor panel among plural steel materials which are solidified on the foundation. CONSTITUTION:A flat steel plate 2a is welded to each end 21, 22 of a long steel material 2 comprising H-steel, and the both ends are provided properly along the side surface in a foundation 1. A flat steel plate 3 is welded to the upper surface of each end 21, 22 of steel materials 2..., while a part protruded from each end 21, 22 of the steel materials 2... on the flat steel plate 3, is put on the upper surface of the foundation 1. The flat steel plate 3 is fixed to the foundation 1 with mounting bolt, and a floor panel is put on plural long steel materials 2, so as to form a floor part. The members necessary for an underfloor structure are the concrete foundation 1 and the long steel materials 2.... A simplified construction with a minimum necessary number of members, is thus achieved.

Description

[Detailed description of the invention] (Industrial application field) This invention relates to an underfloor structure in a building.

(Prior Art) Conventionally, the structure under the floor of buildings such as houses has been explained as follows.

That is, a plurality of bundled stones are placed on the foundation, and a floor bundle is erected on each of these bundled stones.

Then, on top of these floor bundles, the large-sized towels are placed.

Afterwards, joists were passed between these joists, and floorboards were laid on top of these joists.

(Problem M that the invention attempts to solve) However, as described above, the conventional underfloor structure requires a large number of members and has the problem of being time-consuming to construct.

Furthermore, since it requires a large number of members and a lot of time and effort, there is a problem in that the construction cost is high.

In addition, conventional underfloor construction requires the hands of experienced craftsmen, and there is a problem in that it is impossible for amateurs to carry out this construction work.

An object of the present invention is to solve the above-mentioned conventional problems.

In other words, the structure is simple, only the minimum number of parts are required, the construction work is easy, the construction cost is low, even an amateur can perform the construction, and the underfloor construction of a building with a strong structure It's about providing structure.

(Means for Solving the Problem) In order to solve the above problem, the present invention arranges a plurality of long steel members between concrete foundations, and fixes both ends of these long steel members to the foundation. The upper surfaces of these steel materials and the upper surface of the foundation were made substantially flush.

(Function) As the floor material, a long floor panel with floorboards pasted is used, and a hook is stretched between the plurality of long steel materials described above.

Therefore, the only components required for the underfloor structure are a concrete foundation and long steel members.

In this way, the underfloor structure of the present invention does not require as many members as conventional underfloor structures, and may use the minimum number of members required.

This makes the construction work easy and even an amateur can perform the construction work.

Moreover, the structure becomes sturdy.

(Example) Hereinafter, an example of the underfloor structure in a building according to the present invention will be described based on the drawings.

FIG. 1 is a perspective view of an underfloor structure in a building according to the present invention, and FIG. 2 is a partially enlarged perspective view thereof.

As shown in the figure, the underfloor structure of this invention has a plurality of long steel members 2 arranged between a concrete foundation 1,
Both ends 2L22 of these long steel members 2... are fixed to the foundation 1... so that the top surfaces of these steel members 2... and the top surface of the foundation 1... are almost flush with each other. This is what I did.

In this embodiment, H-shaped steel is used as the long steel material 2.

Then, the flat steel materials 2a are welded to both ends 21, 22 of the long steel materials 2 made of these H-shaped steels, so that both ends are well attached to the inner surface of the foundation 1. It is formed like this.

In addition, at both ends 21 and 22 of these steel materials 2...
A flat steel plate 3 is welded to each of the upper end portions thereof.

The portions of these flat steel plates 3 that protrude from both ends 2L22 of the steel plates 2... are placed on the upper surfaces of the foundations 1....

These flat steel plates 3 are embedded in the foundations 1, and the upwardly protruding attachments are fixed to the foundations 1 with bolts (not shown).

Note that the symbol T in the figure is on the foundation under the floor.

As mentioned above, between the plurality of long steel members 2 in the constructed underfloor structure, there is a floor material consisting of a long floor panel with floorboards pasted, although not shown. The floor of the building is then formed.

Therefore, the only members necessary for the underfloor structure are the concrete foundation 1... and the long steel members 2... (in this example, the flat steel members 2a and 3 are also integrated, so the steel members 2... ) may be used.

In this way, the underfloor structure of the present invention does not require as many members as conventional underfloor structures, and may use the minimum number of members required.

This makes the construction work easy and even an amateur can perform the construction work.

Moreover, the structure becomes sturdy.

(Effects of the Invention) As explained above, the present invention arranges a plurality of long steel rods between concrete foundations, fixes both ends of these long steel rods to the foundation, and connects these long steel rods to the foundation. Since the upper surface of the steel material and the upper surface of the foundation are substantially flush with each other, the following effects are achieved.

In other words, the structure is simple, only the minimum number of parts are required, the construction work is easy, the construction cost is low, even an amateur can construct it, and the structure is sturdy. .
