Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-story building structure, and more particularly to an improvement in the installation structure of stairs and a main body of the building other than the stairs of a wooden building having a plurality of floors.

[0002]

2. Description of the Related Art Generally, in a wooden building having a multi-story building structure, a staircase is formed as a part of an indoor structure inside a building body.

That is, in order to make the strength of the entire stairs sufficient, the landing part of the stairs is supported with sufficient strength, and in order to stabilize the entire stairs, the structure of the main body of the building The stairs are constructed by sufficiently connecting and connecting the spaces.

[0004]

However, in a wooden building having a plurality of floors, when stairs are formed inside the building body as in the prior art, the stairs are open to the outside of the building. Therefore, the function of the evacuation route to the outside of the building could not be fully fulfilled in the event of a disaster.

Further, when the number of floors of a building increases, it becomes difficult to make the structural strength of the staircase sufficient only by connecting and connecting it to the building main body, and since the staircase is constructed, the construction cost is reduced. There was a problem that the whole became expensive.

In order to increase the structural strength of the stairs,
It may be made of iron, but if it is erected on the floor, there is a problem that the wooden floor may not be able to bear the weight and may be damaged.

The present invention has been made to solve the above problems, and its purpose is to effectively function as an evacuation route in a wooden multi-storey building and without damaging the floor. It is intended to provide a multi-story building structure capable of constructing a stairway portion which is relatively inexpensive and has high structural strength.

[0008]

In order to achieve the above object, a multi-storey building structure according to the present invention is a multi-storey building structure having a plurality of floors and a stairway portion formed outside, and is constructed by a wooden structure. And a building main body having a recessed space formed inwardly from one side wall for installing the staircase, and an iron building member, and the side wall is a separate body from the building main body. It is characterized in that the staircase portion which is formed without being provided and is installed in the recessed space of the building main body portion is erected on the same foundation.

[0009]

According to the multi-story building structure having the above construction, the building body of the building is made of wood, but the staircase is made of an iron construction member separately from this.

The building body is entirely formed by previously securing a recessed space for installing the staircase formed of an iron construction member later. Therefore, it is possible to construct the entire building by first constructing the main body of the building in advance with a wooden structure and then setting it so that a separately constructed staircase made of iron is fitted in the recessed space for the staircase.

Further, the staircase portion is formed without providing the side wall itself, and can be constructed as an extremely simple structure as a whole. That is, since the side wall of the staircase can be formed by utilizing the wall facing the recessed space for installing the staircase of the main body of the building, the staircase need only have the main body without the side wall. .

As described above, the building body and the staircase are constructed separately and are separately installed on the foundation. With this structure, the staircase is configured outside the main body of the building independently, so it can effectively function as an evacuation route in the event of a disaster, and the floor of the main body of the building is damaged. There is nothing to do. In addition, since the entire structure can be made of a high strength iron construction member, high strength can be obtained with a simple structure without a complicated structure, and the staircase can be constructed relatively inexpensively. It will be possible.

[0013]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a schematic perspective view showing the structure of a multi-story building structure according to an embodiment, and shows a wooden three-story building as an example.

The building body 10 is entirely made of wood. Then, on one side wall surface of the building body 10, a recessed space 1 for installing the stairs is formed toward the inside of the building.
00 is formed. That is, the horizontal cross-sectional shape of the middle portion of the building body 10 is a substantially U-shape. And the recessed space 100 for installing the stairs
Is surrounded by three side walls 12 and 13 of the building body 10. Doors 15 are attached to the entrances and exits of the floors on the back side wall 13. The building body 10 can be built in advance on the foundation 17 separately from the stairs at the building installation site.

Next, the staircase portion 14 is composed of an iron construction member, for example, a steel frame or an iron plate as a main portion, and has a very simple structure as a whole.

In this embodiment, a landing section 18 and floor sections 20 on the second and third floors are installed between a plurality of upright pillars 16, and a staircase 22 connecting them and a handrail 24 formed on the side of the staircase 22 are provided. Etc. are installed.

The staircase portion 14 can be formed wholly or partially at the factory stage. At a construction site, the staircase portion 14 is formed in the recessed space 100 for installing the staircase portion of the building body 10. The staircase portion 14 is formed outside the building body 10 by installing it on the same foundation 17 as the building body 10 so as to be fitted inside. Therefore,
Since it is not necessary to install it on the floor of the building body 10, damage to the floor can be prevented.

Further, the staircase portion 14 is composed of only a portion necessary for climbing and descending the staircase, and no side wall portion is provided, but this is the recessed space 100 for installing the staircase portion of the building body 10. When the stairs 14 are installed in the building main body 1
It is based on the fact that the side wall 12 surrounding the recessed space 100 of 0 functions as the side wall of the staircase portion 14, and therefore it is not necessary to provide this.

According to the above-mentioned embodiment, the building body 10 is made of wood, but the staircase 14 is made of an iron structure separately from this. Therefore, even if the structure is simple, its structural strength is extremely high, and it is not necessary to connect and connect it to the structure of the building body 10 in order to strengthen the structure. In this way, since the staircase portion 14 is independently configured outside the building body portion 10, the staircase portion 14
Will effectively function as an evacuation route in the event of a disaster.

Further, since the staircase portion 14 is formed of a relatively inexpensive steel construction member, the staircase portion 14 is formed of a wooden structure, and in order to obtain sufficient strength, the building body 1
It is possible to make the construction cost cheaper as compared with the case where the construction is performed while being connected to 0.

Further, also in the construction on the building body 10 side, it is possible to avoid the complication of the structure due to the construction of the internal stairs, so that the construction work can be further simplified.

The present invention is not limited to the above embodiment, but various modifications can be made within the scope of the invention.

For example, in the above embodiment, a three-story wooden building is shown as an example, but the present invention is not limited to this, and it is of course possible to apply it to a two-story wooden building. .

[0025]

As described above, according to the multi-storey building structure according to the present invention, the staircase can be constructed outside the building main body even in a multi-storey wooden building.
The stairs can effectively function as an evacuation route.

Further, since only the staircase is constructed of the steel construction member separately from the building body and is installed on the same foundation as the building body, sufficient strength can be obtained even with a simple structure. Thus, the construction work can be simplified and the construction cost can be reduced, and the floor of the building body can be prevented from being damaged.
