Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a basic structure of a seismic structure house.

[0002]

[Prior art]

 Since conventional houses were firmly fixed to the foundation, they were vibrated integrally with the foundation due to an earthquake, and were often destroyed or collapsed by a large earthquake.

[0003]

[Problems to be solved by the device]

 The present invention aims to provide a foundation structure for a house that is earthquake resistant. It also aims to provide the basic structure of a house that minimizes damage and collapse due to an earthquake and facilitates restoration.

[0004]

[Means for Solving the Problems]

 The present invention is configured as follows. That is, the upper surface of the lower metal frame 2 integrally fixed to the upper portion of the base portion 1 and the lower surface of the upper metal frame 4 integrally fixed to the lower portion of the house portion 3 are combined and joined together by the shear pin bolts 5. And the stoppers 6 for limiting the horizontal movement distance of the upper metal frame 4 are formed in one of the upper and lower metal frames, and the total shear strength T of the shear pin bolts is the same as that of the upper metal frame. When the total weight of the structures above this is W and the friction coefficient between the upper and lower metal frames is M, it is selected to be a value obtained by subtracting the product of W and M from 1.0W to 2.0W. The basic structure of the house.

The base portion 1 may be a conventional reinforced concrete, and a lower metal frame 2 having upper and lower flange surfaces such as H-shaped steel may be integrally fixed to the upper portion thereof. Similarly, an H-shaped steel or the like is also integrally fixed to the lower part of the house part 3, the lower surface of the upper metal frame 4 and the upper surface of the lower metal frame are aligned, and the two are joined by a shear pin bolt 5. The total shear strength T of the shear pin bolt is 1.0 W to 2.0 W, where W is the total weight of the upper metal frame and the structure above it and M is the friction coefficient between the upper and lower metal frames. It is better to select a value that subtracts the product of M and M. When the total shear strength T of the shear pin bolt is selected to be 1.0 W, the shear pin bolt withstands an earthquake strength up to about 1.0 times the gravitational acceleration, and above that, it breaks. When the total shear strength T of the shear pin bolts is selected to be 2.0 W, the shear pin bolts can withstand the earthquake strength up to about 2.0 times the gravitational acceleration, and if the earthquake is more than that, the shear pin bolts will be destroyed and the house will be damaged. It is cut off from the base part. It is appropriate to select the value of T within the range of 1.0W to 2.0W from the seismic strength of existing houses. At this time, the horizontal movement distance of the upper metal frame 4 is limited by the stopper 6 provided on one of the upper and lower metal frames, and the house part is prevented from falling from the foundation part.

[0006]

[Operation 1] By selecting the total shear strength T of the shear pin bolts in the range of 1.0 W to 2.0 W, the shear pin bolts 5 will not be damaged in a relatively small earthquake that does not damage the house, In a large earthquake that will cause significant damage to the house, the shear pin bolt 5 will be damaged, and the house will be cut off from the foundation, preventing damage to the house.

[0007]

[Operation 2] Even if the shear pin bolt 5 is damaged and the house is cut off from the foundation part, the horizontal movement distance of the house part is limited by the stopper 6 and it is possible to prevent the house part from falling, and the restoration work is performed. Is easy.

【Example】

 As shown in FIGS. 1 and 2, an H-shaped steel lower metal frame integrally fixed to the upper part of the base part 1 and an upper flange surface of the H-shaped steel integrally fixed to the lower part of the house part 3 The lower flange surface of the metal frame 4 is aligned with each other, and the two are joined by a shear pin bolt 5. The lower metal frame is provided with stoppers 6 for limiting the horizontal movement distance of the upper metal frame 4 on all sides and inside the metal frame. The total shear strength T of the shear pin bolts is 1.0W to 2.0W, where W is the total weight of the upper metal frame and the structure above it, and M is the friction coefficient between the upper and lower metal frames. The basic structure of the house, which is selected as the value obtained by subtracting the product of W and M.
