Description

  The present invention relates to a method for assembling an earthquake-resistant shelter capable of withstanding an excessive load caused by a building or the like collapsed from above in the event of an earthquake, and an earthquake-resistant shelter.

  While the arrival of a huge earthquake is anticipated, there is a concern about the occurrence of a serious accident in which a resident becomes the underlay of a collapsed building when the building collapses due to insufficient seismic strength of a building such as a house. Therefore, it is necessary to grasp the seismic strength of the building and to reinforce the building if the seismic strength is insufficient. However, even if it is determined that the seismic strength is insufficient due to seismic diagnosis, especially in old houses, etc., it may not be easy to go through the remodeling because a large amount of cost is required for remodeling to increase the seismic strength. Many. In contrast, an earthquake-resistant shelter that can withstand building collapse due to an earthquake is installed in the bedroom or living room, and a sleeper, etc. is housed inside it to escape into the earthquake-resistant shelter against the occurrence of an earthquake. In addition, since sleeping on a bed in a shelter at night, it is possible to avoid serious damage caused by collapse of the building. In addition, such earthquake-resistant shelters are attracting attention as countermeasures against large earthquakes because they are significantly less expensive than remodeling the building itself.

Conventionally, as this type of earthquake-resistant shelter, a floor frame part made up of a plurality of floor frame members arranged on the floor of a room, an upper surface part made up of a plurality of upper frame members arranged on the top, a floor frame member, 2. Description of the Related Art There is known an earthquake-resistant unit having a side surface portion made up of an upper frame member and a plurality of support members connecting them, and an inner region surrounded by the side portion. The earthquake-resistant unit further includes a plurality of beams whose upper surface portion connects the upper frame member, and each side surface portion has an upper end portion that connects one of the upper frame member and one of the column members, and a separate column member. A plurality of braces having a lower end portion connecting one of the two and one of the floor frame members. As described above, the earthquake-resistant unit is provided at a low cost by combining the floor frame member, the upper frame member, and the support member with an inexpensive thinning material.

  However, in the above earthquake-resistant unit, a floor frame portion and an upper surface portion are prepared, and a support member and a brace are combined with the floor frame portion, and the upper surface portion is combined therewith. For this reason, it is very troublesome to carry the floor frame part and the upper surface part into the room, and it is also very troublesome to install the upper surface part on the strut and the brace, and it is impossible to assemble by one person's work. There is a problem of having multiple people. Further, the connecting portions such as the floor frame member, the upper frame member, and the column member are not particularly those using an earthquake-resistant connecting member. Therefore, there is concern about the seismic strength when a large load is applied from the top due to the collapse of the house due to the earthquake, and it is conceivable to increase the number of timbers to increase the seismic strength, but this also increases the cost of components and assembly become.

On the other hand, as shown in Patent Document 2, the floor surface, the peripheral side surface, and the ceiling surface constituting the indoor space are formed along the indoor side with corners formed by intersecting each other as an intersection line, There is an indoor earthquake-proof defense frame in which a solid three-dimensional frame is formed in a room by disposing metal corner members such as aluminum alloy and joining the intersections of the corner members with connecting members. However, since this defense frame is made of metal, it requires a considerable thickness in order to have earthquake resistance, which increases in weight and cost, and is also very portable to assemble in a small room. However, there is also a handling problem of having a large number of people.

Further, although not shown on the ceiling side, a bracing beam material can be provided between the beam material and the intermediate beam material, and this also increases the strength on the ceiling surface side.

  In the embodiment, the number of intermediate column members 19 is not limited to two on one side, but may be one or three or more in terms of seismic strength. Furthermore, in the said Example, although a beam material is two steps, it can also be made into three steps or more. Moreover, in an Example, the number of intermediate beam materials is not restricted to five, It can also be set as the number of other than that in relation to seismic strength. In the embodiment, the intermediate beam member is single, but two or more intermediate beam members can be stacked.
