DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a general house, a store,
The present invention relates to an earthquake-resistant room having an earthquake-resistant structure in a wooden building such as an office, a factory, and a warehouse.

[0002]

2. Description of the Related Art Conventionally, as a method of protecting human lives and household goods from collapse and damage of a building due to an earthquake, a steel frame structure in which a steel frame is assembled in a frame shape in a desired room of the building is constructed.
The interior has been converted to an earthquake-resistant room. Japanese Patent Application Laid-Open No. 9-4275 is an example of the earthquake-resistant room. The steel frame structure disclosed in the publication includes a steel frame base, a plurality of steel columns connected to at least corners of the steel frame base, and a top end portion of the steel column in a desired room of an existing building. Steel framed beams.

[0003] A cubic steel frame structure formed by a steel frame base, a steel column and a steel frame beam is mounted on a base floor made of soil or concrete in a room to be installed.
The steel frame beam is supported on a base floor by a steel column, and is arranged below the existing ceiling so as not to contact the existing ceiling.

When an earthquake occurs, the steel frame structure forms a strong room, and even if the building collapses or is damaged,
Only this room remains without collapse.
And if people evacuate to this room, their lives and household goods will be
Will be protected.

[0005] However, in the conventional earthquake-resistant room, the steel frame structure is only mounted on the base floor.
Moreover, since the steel frame beams do not support the floor beams and the land beams, they do not necessarily strongly support the existing buildings. For this reason, the steel frame structure itself is strong and hard to collapse and break, but has a low ability to reinforce the building, it is difficult to suppress the collapse of the roof and the floor on the second floor, and the effect of preventing the building from collapsing and damage Was a problem. The present invention has been made in view of such circumstances, and an object of the present invention is to prevent collapse and collapse of a building while preventing collapse and damage of an earthquake-resistant room due to an earthquake, and to correct distortion of a building.
It is to provide that seismic room.

[0006]

Next, the seismic room 2 in the present embodiment
The construction method will be described. First, the floor, ceiling, and walls of the existing room to be renovated into the earthquake-resistant room 2 of the building 1 are removed. Next, as shown in FIG. 11A, the ground 5a is dug down to the ground 5b.

Then, the reinforcing columns 30 are arranged at the four corners of the aseismic room 2 so that the lower ends thereof ride on the bottom protrusions of the cloth foundation 10. The reinforcing columns 30a and 30b face the existing column 20 and are arranged such that the lower ends ride on the bottom protrusions of the cloth foundation 10. Next, the bottom of the cloth foundation 10, the ground 5, and the reinforcing columns 30,
A solid foundation 15a is cast so as to cover 30a and 30b.

As shown in FIG. 11B, a reinforcing bar 16 assembled in a frame shape and a grid shape is placed on the solidified solid foundation 15a. Then, a solid foundation 15b is poured from above, and after the solid foundation 15b is solidified, as shown in FIG. 11 (c), the reinforcing columns 30, 30a, 30
c is fixed to the solid foundation 15b by the reinforcing metal member 31b. As a result, the reinforcing columns 30, 30a, 30b
It will be firmly fixed to the cloth base 10.

Next, the reinforcing frame 40, the reinforcing beam 50, the cross beam 33, and the brace 34 are connected and fixed to the reinforcing columns 30, 30a, 30b, and the steel frame structure 3 is assembled. At this time, the existing columns 20 and the floor beams 22a and 22b are jacked up and moved to a position where there is no original distortion. In this state,
Using the fixing bracket 32, the existing column 20 is connected to the reinforcing columns 30a, 3a.
By fixing to 0b, the existing pillar 20 is fixed at a correct position. In addition, the reinforcing beams 50 and the floor beams 22a, 22
b, by sandwiching the bundles 55a and 55b,
The floor beams 22a and 22b are fixed at correct positions. After that, even if the jack-up is stopped, the existing pillars 20 and floor beams 22
a, 22b does not return to the original distorted position.

The existing columns 20 and the floor beams 22a and 22b, which form the skeleton of the building 1, are corrected. As a result, the distortion of the whole building 1 is corrected and prevented, and the seismic strength is increased. , Caused by the distortion of the building 1,
Problems such as the window 27 and the doors 63a and 63b not being opened can be improved.

The bundles 55a and 55b in this embodiment have a structure which can be easily expanded and contracted, and the floor beams 22a and 55a having different thicknesses.
22b can be pressed. In addition, reinforcement beam 5
0 and the floor beams 22a, 22b, the bundle 5
By expanding and contracting 5a and 55b, it is also possible to finely adjust the parallelism of the floor material 21 on the second floor. From these facts, the second floor material 21 is firmly supported by the ground 5, and a heavy object such as a piano or a bookshelf can be placed on the second floor material without being aware of the collapse of the second floor material 21. It can be placed on the material 21. Each brace 34, 41, 52 has
A turnbuckle may be provided so that the length can be adjusted. Thereby, the distortion of the entire steel frame structure 3 can be adjusted.

Finally, the new floor member 60, the new wall member 61 and the new ceiling member 62 are provided inside the steel frame structure 3, whereby the earthquake-resistant room 2 is completed. By arranging the new flooring material 60 directly on the reinforcing floor 40, in case of an earthquake,
It is possible to prevent the new floor material 60 from being collapsed.

According to the aseismic room 2 of this embodiment, the steel frame structure 3 is fixed to the cloth foundation 10, and the floor beams 22a and 22b are provided.
, The room sharing the existing pillars 20 is reinforced while securing the earthquake-resistant strength of the earthquake-resistant room 2 itself. Therefore, the earthquake-resistant room 2 forms the reinforcement of the whole building 1, increases the earthquake-resistant strength of the building 1, and can prevent the building 1 from collapsing and being damaged.

In this embodiment, the case where the earthquake-resistant room 2 is provided in the existing building 1 has been described. However, even in the case of a new building, the steel frame structure 3 may be constructed as part of the construction of the building 1. The present invention is not limited to the existing building 1. In the case of a one-story building, the land beam supporting the roof is connected to the reinforcing beam 50 and the bundle 55a,
By 55b, the roof can be collapsed by supporting, and the building can be corrected. And stores, offices, factories,
It can be installed on wooden buildings such as warehouses, and is not limited to ordinary houses.

[0030]

According to the seismic room of the present invention, the steel frame structure is fixed to the fabric foundation of the building and supports the floor beams and the land beams firmly. Reinforce and increase the seismic strength of buildings. For this reason, collapse and breakage of the building can be prevented. In addition, floor beams and land beams will be jacked up to correct the distortion of the building, and the steel frame structure will be implemented. Then, in jack-up position, through the bundle, to support the floor beams and Rikuhari the reinforcement Kumihari. Thereby, the distortion of the building is corrected, and the distortion hardly occurs. As a result, problems such as the windows and doors not opening due to the distortion of the building can be improved. In addition, since the reinforcing beams support the floor beams, heavy objects such as pianos and bookshelves can be transferred to the supported 22 floors without sinking and collapsing the supported 2 floors. Can be placed. Furthermore, in wooden buildings
The existing columns are connected and fixed to the reinforcing columns.
Room that shares existing pillars while ensuring the earthquake resistance of the building itself
Can also be reinforced.
