Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an earthquake protection device for a general house, and relates to an interior in daily use.

[0002]

2. Description of the Related Art Conventional devices for securing a living space include seismic strengthening of a building to make it a living space, a structure added to the building, an independent shelter, and the like.

[0003]

[Problems to be Solved by the Invention] In the conventional reinforcement to the building and the structure added to the building, there are problems in implementing rental housing users. Also, even if they are owned by themselves, there is a problem that the technical burden and the method are individually different, so that the cost burden is imposed, and the work from the survey to the completion, the construction period, and the like greatly hinder the daily life due to the construction. In addition, there is a problem in the effectiveness against sudden collapse of a building if it is installed away from the daily living space. In fact, in the Great Hanshin Earthquake, there is a fact that many people fell under the collapsed house while sleeping.
Moreover, although it is said that earthquakes will always come, and it is said that it is not unusual for them to come anytime, the reality is that they have not been prepared yet. It is thought that there is little effect, and it is difficult to put it into practice just for that purpose. The present invention intends to provide a simple and low-cost device by limiting the problem to protect human life, which is the purpose of securing a living space, regardless of the structure.

[0004]

First of all, a wooden portion composed of a lower frame (3), a pillar (4) and an upper frame (5) in the present invention is replaced with a wooden frame structure (2) and a steel pipe (7). The portion that forms a net is defined as a shock absorbing net (1), and the steel pipe connecting the shock absorbing net (1) and the wooden framework structure (2) is defined as a steel pipe column (6), and will be used in the following description. This indoor framework structure is roughly characterized by comprising two parts, a wooden framework structure (2) and a shock absorbing net (1). First, a lower frame (3) made of timber having sufficient strength, a pillar (4),
A wooden frame structure (2) having sufficient strength is made by the structural material of the upper frame (5). Furthermore, a steel pipe column (6) is provided on the upper part of the wooden frame structure (2), and a steel pipe (7) such as a standard scaffolding steel pipe is joined directly below the existing ceiling surface (C) to form a shock absorbing net (1). ) Is installed. At this time, a buffer distance (A) is appropriately secured between the wooden frame structure (2) and the shock absorbing net (1). The above is the existing indoor floor of the existing building (B)
The solution is to install it above the building, independent of the building.

The present invention is to secure a living space and cannot guarantee that it will not be damaged. However, it can be said that seismic retrofitting work on existing buildings is also similar to collapse. It does not constitute a reason for denying the completeness of the invention. In addition, it should be noted that there are both arguments for safety seat belts and airbags of automobiles with respect to secondary events that can occur according to the present invention.

[0006]

The impact absorbing net (1) located at the top receives the falling structural material when the building collapses, absorbing the impact force within the buffer distance (A). Next, the load applied to the shock absorbing net (1) is distributed to the lower frame (3) by the upper frame (5) of the wooden frame structure (2) through the pillars (4), and the existing indoor floor surface (B ) To. As a result, a living space is secured without damaging the wooden framework structure (1).
