Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a house with an earthquake-resistant evacuation room.

[0002]

2. Description of the Related Art Houses are important in conducting daily living, sales, business, and the like, and require high security. From this point of view, building design standards are established for the foundations, columns, beams, opening areas of walls, etc., and construction is carried out in accordance with them. However, if the house is a wooden house, for example, which has been deteriorated after a considerable number of years since its construction, the beam, girder, column, etc. will be subjected to a load exceeding the earthquake resistance when a large earthquake occurs. The strength member is damaged and broken, and at the same time, the roof acts as a large load. As a result, the entire building collapsed, causing problems such as collapse, damage to members, furniture, and underlaying of household goods, resulting in loss of life, serious injury, and damage or loss of valuable items. . As a countermeasure, it is necessary to modify the bases, beams, columns, etc. into an earthquake-resistant structure, or to newly build a house with an earthquake-resistant structure, by reaching the entire house, but all of these methods are expensive and costly. It was time-consuming and poor economic and immediate effect.

As a countermeasure against this, Japanese Patent Laid-Open No. 57-180766 has been proposed.
Japanese Patent Application Laid-Open Publication No. H11-163840 proposes that an evacuation box having a ceiling panel, four columns, a floor panel, and a side panel and having three sides open and serving as an entrance is disposed in a building. However, this prior art firstly has a low seismic resistance due to a flexible structure in which a metal plate is mainly used and joined by a connecting plate and three surfaces are completely open, so that the structure on the second floor is not used. When it collapsed,
There is a problem that it is difficult to reliably receive a large load. Secondly, since the ceiling plate has a structure in which a connecting plate is passed between the side plates and the columns to perform welding, there is a problem that the welding machine must be used in the building, which is dangerous.
