Abstract

PROBLEM TO BE SOLVED: To receive an external force acting on a steel-made basement through the wall of a ground building by providing an independent column or reinforcing beam in a position corresponding to the wall of a ground building of the steel-made basement, and providing a bearing wall so as to be situated on the extension line of the wall of the upper building. SOLUTION: An independent column 8 is provided in a position corresponding to the wall of a ground building of a steel-made basement 1, and a bearing wall 9 is provided so as to be situated on the extension line of the wall of the ground building. Each of a floor panel 3, a wall panel 4, and a roof panel 5 is formed by assembling a plurality of shape steels into a rectangular frame having a prescribed size to constitute a reinforcing frame, and mutually bonding the resulting frames having steel plates stuck to one-side surfaces by a plurality of bolts. The independent column 8 and the bearing wall 9 are constituted as, for example, steel columns. Thus, since an external force such as earthquake force acting on the independent column 8 and the bearing wall 9 from the wall 7 of the ground building through the roof panel is received by the independent column 8 and the bearing wall 9, it is surely prevented that the roof of the steel-made basement is deformed thereby, and the ground building is distorted according to it.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of floor panels each for a floor, a wall and a roof,
The present invention relates to a steel basement that is provided with wall panels and roof panels and is constructed with a relatively large living room or opening.

[0002]

2. Description of the Related Art Recently, base houses are often provided in ordinary houses, and this type of basement shortens the construction period.
It is constructed by connecting a plurality of floor panels for a floor, a wall and a roof respectively, and connecting a wall panel and a roof panel with a plurality of joining bolts in order to save labor in construction.

When the above-ground building is constructed on such a steel basement, the steel basement serves as the foundation of the above-ground building, and not only the weight of the above-ground building but also the pillars of the above-ground building during an earthquake or storm. To receive an external force acting on the wall
As shown in (a), it is better if the steel basement wall 16 is vertically continuous with the above-ground building columns and walls 17.
There is no particular problem because the external force acting on 17 is directly transmitted to the wall 16 of the steel basement.

[0004]

However, due to the layout of the basement, for example, because of the desire to provide a large living room or a large entrance / exit as shown in FIG. 8 (b), the pillars and walls of the above-ground building 17 In some cases, it may not be desirable to have a wall 16 underneath, and in such a case the steel basement roof will be subjected to excessive force (the force that pushes and pulls the steel basement due to the rotation of the above-ground building wall). Since the roof of the basement room may be deformed as shown in Fig. 8 (c), and the ground building may be distorted as a result, there was a problem such as being extremely dangerous.

In particular, the steel basement, unlike the conventional basement with a reinforced concrete structure which is integrally constructed, is an assembly type and therefore weak in rigidity and mechanical continuity, so that it is easily affected by a large external force such as seismic force. .

The present invention has been made to solve the above problems, and an object of the present invention is to provide a steel basement that enables effective reinforcement when a large living room or the like is provided in the steel basement.

[0007]

A steel basement according to claim 1 of the present invention comprises a plurality of floor panels, a wall panel and a roof panel, each of which is configured for a floor, a wall and a roof. Provided, and in a steel basement constructed with an above-ground building, an independent pillar is provided at a position corresponding to the wall of the above-ground building of the steel basement, and is located on an extension line of the above-ground building wall. It is constructed by providing a bearing wall.

According to the second aspect of the present invention, in the steel basement of claim 2, in the preceding paragraph, a reinforcing burr is provided at a position corresponding to the wall of the aboveground building of the steel basement in place of the independent pillar, and It is constructed by joining both ends to the wall panel and the bearing wall respectively.

The steel basement according to the third aspect of the present invention is constructed by extending the reinforcing beam to the above-ground building side and bridging it over in the second aspect.

The wall panels that make up the wall, and the reference numeral 5 is the wall panel 4,
It is a roof panel that spans 4 spaces and forms the roof of the steel basement 1. Further, reference numeral 6 is an above-ground building (hereinafter referred to as “shed”) constructed on the roof panel 4 of the steel basement 1, and 7 is a wall of the shed 6.

Further, reference numeral 8 indicates an independent column provided in the steel basement 1 located just below the wall 7 (above the wall core) of the shed 6, and receiving an external force acting on the wall 7, and 9 indicates an extension of the wall 7. A bearing wall which is located on the line and is provided in the steel basement 1 and receives an external force acting on the wall 7 together with the independent pillar 8, and the reference numeral 10 indicates the independent pillar 8
And the wall panel 4, and between the independent column 8 and the bearing wall 9 are large openings such as doorways.

Each of the floor panel 3, the wall panel 4 and the roof panel 5 constitutes a reinforcing frame 11 by assembling a plurality of shaped steels such as channel steel and L-shaped steel into a rectangular frame of a predetermined size. A steel plate 12 is attached to one side surface of the reinforcing frame 11 by welding or the like, and is joined to each other by joining with a plurality of joining bolts (see FIG. 7).

The independent columns 8 are constructed as, for example, steel columns or steel reinforced concrete columns having high rigidity so that they can effectively receive the external force acting on the wall 7, and the quality is improved, the production cost is reduced, and the on-site construction is performed. It is manufactured at the factory to save labor, and is configured so that it can be easily installed on the site simply by bolting.

The load bearing wall 9 is also the wall 7 like the independent column 8.
In order to effectively receive the external force that acts on, it is composed of high rigidity such as steel frame and steel frame reinforced concrete, and is manufactured at the factory to improve the quality, reduce the production cost, and save labor on site construction. In the field, it is configured so that it can be easily installed simply by bolting.

In such a structure, the wall 7 of the above-ground building
External force such as seismic force acting on the independent pillar 8 and the bearing wall 9 from the roof panel through the roof panel is received by the independent pillar 8 and the bearing wall 9, which causes the roof of the steel basement to be deformed, and accordingly As a result, the ground building is securely prevented from being distorted.

Embodiment 2 of the Invention 3 to 5 show an embodiment of the invention according to the second aspect of the present invention. In the drawings, the same parts as those of the first embodiment of the invention are designated by the same reference numerals and the description thereof will be omitted. Omit it. Further, reference numeral 13 is provided over the upper end portion between the wall panel 4 and the load bearing wall 9 instead of providing the independent column 8, and the wall panel 4 and the load bearing wall 9 constitute a rigid frame structure so that the wall 7 of the above-ground building is constructed. Reinforcing beam that effectively receives external force from. The reinforcing beam 13 is configured as a high-rigidity beam such as a steel beam or a steel-framed reinforced concrete beam so that it can effectively receive the external force acting on the wall 7, and it also improves quality, reduces production costs, and saves labor in field construction.
