The present invention relates to a disaster prevention underground shelter that serves as an evacuation facility in the event of a natural disaster or an emergency disaster, and is related to a disaster prevention underground shelter that is excellent in earthquake resistance, waterproofness, functionality and safety in addition to shielding and durability. ..

Various things have been proposed for underground shelters and basements. The underground shelter minimizes the internal impact of blast waves, shock waves, vibrations, radiation, dust, gas, fire, heat, electromagnetic waves, etc., in a form that suits construction costs and ground conditions. It is required to fasten.

Especially in disaster prevention underground shelters, the primary purpose is to safely protect people and goods inside against various possible dangerous elements from the outside, and it is robust and has excellent living functionality, and science for each dangerous element. Requires a protective structure.
On the other hand, the basement that is common to provide space in the basement is often used as a living room for hobbies and entertainment such as an audio room, music lesson room, living room, bedroom, etc., and has a structure that meets the legal conditions as a residential basement. It is hoped that it can be constructed at a lower cost with a shorter construction period within the range.

For example, the main body structure of the underground shelter described in Patent Document 1 is a box-shaped structure made of high-strength concrete on which a preventive coating is formed on a pressure plate supported by a plurality of piles driven into the ground. A shelter inner shell and a durable partition wall are provided, and the outer surface of the wall and ceiling surface excluding the bottom surface of the shelter inner shell is covered with a shelter outer shell made of an iron plate, and the outer surface of the iron plate is covered with a waterproof coating to cover the shelter inner shell. The structure is such that the waterproof coating film between the bottom surface of the concrete and the pressure plate is integrally covered.

The main body structure of the basement described in Patent Document 2 has a floor, wall, and ceiling panel in which a metal plate is fixed to the outer surface of a core material such as shaped steel and a non-metal inner plate is fixed to the inner side. The short side direction is a portal ramen structure, and the long side direction is a seismic wall structure, which is assembled into a box-shaped unit, and multiple units are installed and joined. In this basement chamber, the entire outer surface of the metal plate is made of a metal plate to ensure waterproofness and moisture resistance, and as a rust preventive measure for the metal plate, the entire outer surface of the metal plate is coated with an organic solvent coating material and a synthetic resin. It has a structure coated with a film and a synthetic resin mortar.

In this way, the disaster prevention underground shelter is constructed as an evacuation space for natural disasters and emergency disasters. Therefore, it is important to adopt a structure suitable for the purpose. Therefore, it is necessary to devise a unique configuration for each shelter in each component constituting the shelter, and the same applies to the passage between the above-ground entrance and the underground shelter.

That is, ladders and stairs for ascending and descending between the shelter body, which is a living area buried or constructed underground, are often provided in a narrow elevating space, and thus the safety of people and goods in such elevating space. And it requires easy movement.

Currently, a common configuration adopted as a device for raising and lowering between a ground doorway and an underground shelter body is a linear or spiral staircase configuration or a vertically moving ladder configuration.

For example, it consists of multiple landings provided between the ground entrance and the underground shelter, and multiple means of raising and lowering (gangways). From one landing to the next landing, the ramps are used to move up and down, and the multiple landings move up and down each other. The space is high enough to easily pick up luggage placed on the upper landing, and each landing is installed so that it has an area that can stand up to the upper landing, and the gangway is steeply configured as an underground shelter lifting device. Has been proposed (see Patent Document 3).

Further, for example, in an underground shelter connected to a concrete shelter dog, a housing that can be moved up and down by an elevating drive device along one or a plurality of shelter rails fixed to the floor near the inner circumference of the shelter dog. (See Patent Document 4).
