Abstract

PROBLEM TO BE SOLVED: To form a space for installing a facility having high freedom between the floor girder and floor face material of a building unit and simplify the structure of a floor beam by mounting the floor beam so that the upper surface thereof is higher than the upper surface of the floor girder. SOLUTION: A U-shaped sectional connecter 16 is mounted on the web 12A of a ripped C-shape steel floor girder 12 forming the floor structural body of a building unit at prescribed intervals. The end part of a floor beam 13 is put between both raised plates 16A, B of the connecter 16, and the floor beam 13 is mounted so that an upper flange 12B is higher than the upper flange 12B of the floor girder 12. Otherwise, the end of the web 13A of the floor beam 13 is bent to form a connection part 17, whereby the floor beam 13 may be directly mounted on the web 12A of the floor girder 12. A setting route for piping having a high freedom can be formed between a floor face bar and the floor girder 12 with a simple structure without setting the floor beam 13 into a protruding form, and the reduction in sectional strength by notch effect of the floor beam 13 can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a floor structure of a building unit.

[0002]

2. Description of the Related Art Conventionally, as described in Japanese Patent Application Laid-Open No. 5-295798, a convex joist is used as a floor structure of a building unit capable of securing an installation space for equipment members such as piping. In some cases, both ends are hung on the floor girders on both sides, and a floor material is placed on the middle part of the joist. Thereby, a gap serving as an equipment space is formed between the floor girder and the floor surface material, and a piping portion can be connected to another adjacent building unit through the equipment space. .

[0003]

However, in the prior art, since the floor panel is installed above the floor girders, the joists need to have a convex shape, and the configuration is complicated.

[0004] Further, both ends are notched in a step-like manner with respect to a middle-height intermediate portion of the joist to obtain a convex shape, and the step becomes brittle due to the notch effect, thereby impairing the cross-sectional strength of the joist.

[0005] It is an object of the present invention to simplify the structure of a floor component and to easily form a space for equipment below the floor material without deteriorating its cross-sectional strength.

[0006]

According to the present invention, there is provided a floor structure of a building unit in which a floor girder supports a floor girder and a floor panel is supported on the floor girder. The upper surface of the floor girder is installed higher than the upper surface of the floor girder, and a space for equipment is formed above the floor girder.

According to a second aspect of the present invention, there is provided a floor structure of a building unit in which a floor girder supports a floor girder and a floor material is supported on the floor girder.

[0008] A floor receiving part is provided on the upper surface of the floor beam, a floor surface material is supported on the floor receiving part, and an equipment space is formed above the floor girders.

According to a third aspect of the present invention, in the first or the second aspect of the present invention, the floor beam is provided with a facility hole formed therethrough.

According to a fourth aspect of the present invention, there is further provided the present invention as set forth in the second or third aspect, wherein a thick-walled floor material and a thin-walled floor material are juxtaposed on the floor beam. The flooring is supported directly on the floor girder or via a short floor support, and the thin wall flooring is supported on the floor girder via the tall floor support. The finished surface height of the surface of the face material is equal to that of the thin floor material.

[0011]

According to the first aspect of the present invention, the following effects are obtained. When supporting the floor beam on the floor beam and supporting the floor surface material on the floor beam, simply install the upper surface of the floor beam higher than the upper surface of the floor beam to make the floor beam a convex shape. The space for equipment can be formed in the upper part of the floor girders and below the floor surface material.

In the above description, the floor beam has a simple structure with no irregularities on the upper surface and is easy to manufacture, and does not involve a reduction in sectional strength due to the notch effect.

In the above description, since the floor beam is usually less rigid than the floor beam, the beam back is not higher than the floor beam, and as a result, the lower surface of the floor beam is higher than the lower surface of the floor beam, and A certain gap is formed below the small beam, and this gap can be used as a space for equipment. Thereby, the degree of freedom of the installation route of the pipes under the floor is increased.

According to the present invention, the following effects are obtained. When supporting the floor beam on the floor girder and supporting the floor surface material on the floor girder, a floor receiving part is interposed between the floor girder and the floor girder, and the floor girder has a convex shape The space for equipment can be formed in the upper part of the floor girders and below the floor surface material.

In the above, the floor beam has a simple structure with no irregularities on the upper surface and is easy to manufacture, and there is no reduction in sectional strength due to the notch effect.

In the above, a fixed gap corresponding to the height of the floor receiving part is formed between the portion of the floor beam where the floor receiving part is not provided and the floor surface material. It can also be used as a storage space. Therefore,
The degree of freedom of the installation route of piping under the floor increases,
In addition, the equipment can be easily installed simply by placing the piping on the floor beam.

According to the third aspect of the present invention, the following operations are provided. Since the equipment holes are formed through the floor beam, the installation route of the piping under the floor can be variously set.

According to the present invention, there is provided the following operation. Depending on the presence or absence of floor receiving parts on the floor beam, or the selection of the height of the floor receiving parts, the thick floor surface material and the thin wall floor material are juxtaposed on the same floor beam, and The finished surface heights of those surfaces can be made uniform. Therefore, in the same building unit, a Japanese-style room using a tatami floor as a floor material and a Western room using a floor panel as a floor material can be juxtaposed without any step on the floor.
