Description

[Detailed description of the invention] The present invention relates to an outer peripheral wall structure of a building.

FIG. 1 shows the outer peripheral wall structure of a conventional prefabricated house, where 1 is an outer wall panel, 2 is a framework, 3 is an inner wall panel, and 4 is an interior base material. The inner wall panel 3 is a wooden frame 5 with a foamed resin insulation material 6 loaded inside it.
The inner wall panel 3 and the outer wall panel 1 are fixed to the framework 2 using fasteners 7 and the like. In the exterior wall structure of such a building, electricity and television code 8
etc., it is necessary to partially tear off the foamed resin insulation material 6 of the inner wall panel 3. In the figure, numeral 9 is the empty space where the foamed resin insulation material has been torn off.

If the heat insulating material 6 is torn, a problem arises in that the insulation performance deteriorates in the void created by the breakage. Further, the outlet box 10 also has the problem of having to be installed by tearing the interior base material 4 and the heat insulating material 6.

If a void is created in the wall insulation material in this way, a serious problem will occur in the event of a fire or the like. There was a risk that the flame would enter the gap 11 provided between the outer wall panel 1 and the inner wall panel 3 through this cavity and spread through this gap. This problem also occurred because the joints between the inner wall panels 3 were large.

In view of these problems, the present invention enables wiring for electricity, television, etc. inside the wall without partially tearing off the insulation material installed on the indoor side of the building framework, and is fireproof. The purpose is to provide a highly functional outer wall structure for buildings.

The configuration of the present invention will be explained below based on embodiments shown in the drawings.

Figures 2 and 3 show the outer peripheral wall structure of a building according to the present invention, in which an outer wall panel 21 is attached to the outdoor side with a building frame 20 in between, and a hard inorganic heat insulating board 22 is attached to the indoor side. has been done. Building frame 20
may be formed by forming a frame of lip channel steel. The outer wall panel 21 may be formed by sandwiching a foamed resin heat insulating material between two hardboards in a sandwich shape, or may be made of lightweight foamed concrete, and its shape is not limited. As the hard inorganic heat insulating board 22, for example, a lightweight foamed concrete board whose main component is pearlite or the like is used.

A film or sheet-like moisture-proofing material 23 is attached to the indoor side of the hard inorganic heat insulating board 22, and slats 24 are arranged at appropriate intervals on the indoor side of the moisture-proofing material 23, and the slats 24... An interior base material 25 such as gypsum board is attached to the interior side of the room. Moisture proof material 23
For example, so-called silver paper, aluminum foil, etc. are used. The timber 24 may be made of wood in addition to channel steel. Note that an interior finishing material (not shown) is pasted on the indoor side of the interior base material 25.

In the figure, 26 is an inner space formed between the moisture proofing material 23 and the interior base material 25, and 27 is an outer space formed between the hard inorganic heat insulating board 22 and the outer wall panel 21. Also, 28 is the outlet box, 2
9 is the electrical code.

In addition, the outer wall panel 21 for the building framework 20
and a hard inorganic heat insulating board 22 or a bamboo material 24
The interior base material 25 is attached to the interior base material 25 by an appropriate attachment and fixing means, but the beams 24, which are arranged at appropriate intervals on the indoor side of the moisture-proof material 23, are attached to the runners 30 made of C-shaped steel. (See Figure 3). The runners 30 are provided so that the top and bottom of the timbers 24 can be fitted and fixed therein. Therefore, since the timbers 24... can be placed at appropriate positions by the runners 30, the joint parts 31,
A piece of wood 24 may be placed at 31 to allow the seams 31, 31 to be completely sealed. Moreover, the sillage material 2 is also applied to the joint 32 of the hard inorganic heat insulating board 22.
It is also possible to completely seal this seam 32 by arranging the joints 32 so that they touch each other.

33 is a concrete foundation, 34 is a joist, and 35 is a flooring material.

In addition, in cold regions etc., the inner space 26 can be filled with rock wool, glass wool, etc. on site to provide insulation reinforcement.

The outer peripheral wall structure of the building of the present invention constructed in this way has the following effects.

Electrical and TV cords can be placed inside the space without damaging the insulation board. Therefore, such wiring work will not reduce the insulation effect of the building. Furthermore, since the space is pre-formed, wiring work is easy. Needless to say, in addition to cords, gas pipes, water pipes, etc. can be easily installed in this inner space. Since the heat insulating board does not break and the joints of the hard inorganic heat insulating board are completely closed, it has high fire resistance. In other words, this insulation board can completely stop the fire.
Moisture-proofing materials can prevent condensation from forming inside the outside space, improving the durability of buildings.
