Abstract

PURPOSE:To provide a heat insulating effect and to improve rigidity, by a method wherein, by the use of a sandwitch panel in which surface panels are laminated to the two surfaces of a light core, such as honeycomb, foamable resin, an indoor inner surface, such as floor, wall, ceiling, is formed. CONSTITUTION:A body part 2 of an underground housing 1 is formed by reinforced concrete and is buried in an underground. An indoor inner surface is formed with a floor part material 3, a wall part material 4, and a ceiling part material 5, and all connections are connected so as to hold air-tightness by a proper means. Each member is plural unit members 3a, 4a, and 5a, made of a sandwitch panel, which are formed by adhering surface plates to both surfaces of a light core, such as honeycomb core, foamable resin, serving as a core. This prevents the occurrence of dew condensation to a wall surface and the like, enables increase of humidity, and permits sharp improvement of living comfort.

Description

[Detailed description of the invention] "Industrial application field" The present invention relates to the internal structure of an underground dwelling.

``Prior Art'' and ``Problems to be Solved by the Invention'' In general, the main body of underground dwellings has a reinforced concrete structure, so moisture from underground tends to seep into the house, resulting in high indoor humidity. Therefore, in structures where the concrete inner wall surface is directly finished with interior materials or decorative walls, etc., dew condensation is likely to occur on the wall surface, etc., and curvature is likely to occur unless a sufficient dehumidification device is installed. However, the durability of the interior parts was poor, and there were many problems with comfort. Therefore, in order to prevent an increase in indoor humidity and condensation, etc., all indoor structures facing the main body are double-layered in order to form an air layer between the concrete inner surface of the main body and indoor walls, etc. Some have a heavy structure, but the disadvantage is that they are extremely expensive because the base structure for forming indoor walls, etc., and the airtight structure to prevent moisture from seeping in are complex, and construction is difficult. there were.

[Means for Solving the Problems J] In view of the above-mentioned circumstances, the present invention has been made to solve the above-mentioned problems of the prior art. Indoor interior surfaces such as floors, walls, and ceilings are formed by sandwich panels to which face plates are attached.

``Function'' Sandwich panels, which have face plates attached to both sides of a lightweight core material such as a honeycomb core or foamed resin, have excellent heat insulation properties without the need for separate installation or special processing. As a result, an indoor area airtightly enclosed by such sand inch panels can prevent dew condensation from forming on walls, etc., and can also prevent moisture from penetrating into the indoor interior, thereby preventing an increase in humidity. It is also possible to prevent this.

In addition, such sandwich panels have high rigidity despite being lightweight and have excellent flatness, so they can be directly attached to concrete walls by adhesive, and even when not directly attached, they are easy to use. It is easy to install because it can be installed on a suitable base structure.

“Example j Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

In FIG. 1, 1 is an underground dwelling, and 2 is a main body of the underground dwelling 1. This main body 2 is made of reinforced concrete and is buried underground. 3. 4 and 5 are a floor member, a wall member, and a ceiling member, respectively, which constitute the indoor inner surface, and the floor member 3, wall member 4, and ceiling member 5 are each made of a lightweight core material such as a honeycomb core or a foamed resin. A plurality of unit floor board members 3a, 3a..., unit wall board members 4a, 4a..., and unit ceiling board members 5 made of sand inch panels are formed by using a core material as a core material and bonding surface boards to both sides thereof.
a.

5a..., each of these unit members 3a, 3
a..., 4a 14a... and 5a, 5a...
By combining and connecting each member 3.
4 and 5 are connected to each other to maintain airtightness between unit members and to other members by appropriate means, and are directly attached to the inner surface of the main body portion 2 by adhesive.

In this embodiment, the floor member 3, the wall member 4, and the ceiling member 5 are each attached to the inner surface of the main body part 2 by adhesive. There is no need to provide any other equipment, and installation is also extremely easy.

The material of the surface plate of each unit member 3a, 4a, 5a is, for example, stainless steel on the side in contact with the main body 2;
Durability can be improved by using a surface plate made of a material with excellent corrosion resistance such as FRP. Further, if asbestos boards are used for the indoor side surface plates of the unit wall board members 4a and the unit ceiling board members 5a, and metal plates such as steel plates or aluminum alloy plates are used for the unit floor board members 3a, a structure with excellent fire resistance and rigidity can be obtained.

In particular, in the case of a sand inch panel using a honeycomb core as a core material, fire resistance can be further improved by using a honeycomb core with excellent fire resistance such as asbestos honeycomb or aluminum honeycomb.

FIG. 2 shows another embodiment of the present invention. In this embodiment, a floor member 3, a wall member 4, and a ceiling member 5 constituting the indoor inner surface are each large enough to fit into the interior space of the main body 2. Each of these members 3.
Each unit member composing 4 and 5 is a unit floor plate member 3a.
, 3a, between the unit wall board members 4a, 4a, and between the unit ceiling board members 5a, 58, respectively, with connecting fittings 6, 6...
At the same time, the joints between the floor member 3 and the wall member 4 and the joint between the wall member 4 and the ceiling member 5 are connected by connecting corner fittings 7, 7, etc., and are assembled into a box shape. ing. Each member assembled into this box shape 3.4
and 5, the floor member 3 is independently disposed on the floor of the main body 2 at appropriate intervals so that there is a space between the support and the inner surface of the main body 2. - It is fixed on the frame 9 installed above.

In this embodiment, an air layer is formed around the floor member 3, wall member 4, and ceiling member 5 that constitute the indoor inner surface, and around the inner surface of the main body 2, so it has excellent insulation properties and is more comfortable to live in. It is possible to improve the

Also, each member 3, 4 and 5 can be assembled by simply connecting them with the connecting fitting 6 and the connecting corner fitting 7,
Since the mounting structure is simple, construction is also easy.

The present invention has been explained above using a normal underground dwelling as an example. However, the underground dwelling of the present invention is not limited to a normal underground dwelling, and includes, for example, an evacuation site in the event of an emergency such as a disaster. This also includes disaster prevention shelters buried underground for the purpose of safety.

``Effects of the Invention'' As detailed above, according to the present invention, since the indoor inner surface is airtightly surrounded by a member made of sand inch panels with excellent heat insulation properties, dew condensation does not occur on the wall surface, etc. In addition, since moisture is prevented from penetrating indoors and an increase in humidity is prevented, the livability can be significantly improved. In addition, since the mounting structure is simple, it is possible to reduce the cost of installation work, etc., and the effects it has are significant.
