Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airtight device for a wall of a frame panel construction method in which an outer wall panel is attached to the outside of a wall frame.

[0002]

2. Description of the Related Art The outer wall of a house is required to have a predetermined heat insulating performance from the viewpoint of energy saving, and along with this, the new energy saving method is required to improve airtightness. Conventionally, in the inner wall portion inside the shaft assembly, airtightness is secured by sticking airtight tape or gasket or both to the joints between the inner wall frames attached to the shaft assembly and between various members. I am trying to do it.

[0003]

In the conventional airtight structure described above, the airtight tape is formed on the indoor side of the joint between the inner wall frame and the inner wall frame, the joint between the inner wall frame and the floor board, and the joint between the inner wall frame and the ceiling substrate. It is to secure airtightness by pasting etc., but it is necessary to work carefully so that there is no gap in the overlapping part of the tapes or it is not easily peeled off. There is a drawback that it takes time. In particular, in the case of the inner wall, the shape of the wall surface is often changed depending on the plan, and there is the inconvenience that the number of site works increases.

Further, since holes for electric wiring and facility piping are opened in the inner wall portion, it is necessary to repair the airtight layer which is broken by the holes, which requires very complicated work. There are drawbacks.

The present invention has been made for the purpose of solving the above-mentioned conventional defects and providing an airtight structure of a wall body which is easy to construct and has an excellent airtight performance.

[0006]

In order to solve the above-mentioned problems, in the present invention, an airtight material is attached across the outer surfaces of the frame members adjacent to each other and is attached to the outside of the frame. A moisture-proof material is stretched on the back surface of the outer wall panel, and the moisture-proof material end portion of each outer wall panel end portion is brought into close contact with the outer surface of the airtight material, so that the airtight layer made of these airtight material and moisture-proof material is substantially in the wall surface direction. It is characterized by being penetrated in a straight line.

In the above, the invention of claim 2 of this application is characterized in that both the frame frame material to which the airtight material is attached and the moistureproof material attachment portion of the outer wall panel are metal materials.

The invention of claim 3 is also characterized in that the airtight material is rubber having elasticity.

In this specification, the airtightness and the moistureproof material are used properly, but they are substantially the same and the same name is used, and the names are not limited.

[0010]

As described above, since the airtight material is attached to the outer side of the frame frame in advance, and the end portion of the moistureproof material of the outer wall panel is pressed against the airtight material, the outer wall panel only needs to be attached. No complicated on-site work is required to maintain airtightness, and an airtight layer with excellent performance can be easily applied.

EXAMPLE FIG. 1 shows an outer wall panel of an outer heat insulating structure filled with a heat insulating material, which is in a state before being filled with the heat insulating material. In the drawings, (1) is a frame of the present invention, which is a pair of left and right vertical frame members (2) made of channel steel.
A pair of upper and lower horizontal frame members made of channel steel similar to (2)
(3) (3) and the groove (4) of those frame materials (2) (3)
(4) ... are arranged in a rectangular frame shape so that they are on the inside. An outer wall plate (5) having substantially the same shape as that of the frame frame (1) is provided on one side surface of the frame frame (1), that is, on the outer surface side, in the longitudinal direction of the frame members (2) (3). The spacers (7), (7), ... Arranged in advance are integrally attached so that a gap (6) is formed between them. The outer wall plate (5) is made of a heat insulating outer wall material such as a fiber reinforced concrete plate.

FIG. 2 shows a state in which a heat insulating material (8) is filled in a space surrounded by the frame (1) and the outer wall plate (5). As the heat insulating material (8), for example, a hard urethane foam or other material having excellent heat insulating performance is used, and by heating and foaming after or at the same time as charging, the groove of each frame material (2) (3) is used. From the inside to the gap (6) between the outer wall plate (5) and the frame (1) is continuously and integrally filled. Further, as shown in FIGS. 3 and 4, the heat insulating material (8) is recessed in the boundary portion between the heat insulating material (8) and the outer wall plate (5), and the vertical direction of the panel (10) is increased. Two air layers (11) are formed so as to penetrate therethrough.

Further, the heat insulating material (8) on the side opposite to the outer wall plate (5) and the surface of the frame (1), that is, the surface on the indoor side are covered with the frame (1) and the heat insulating material (8). Then, the moisture-proof material (12) is attached. This moistureproof material (12)
Is a film obtained by adhering a film obtained by vapor-depositing aluminum foil onto paper, and pasting it on the frame (1) or the like with the surface of the paper being the back side.

FIG. 5 and subsequent figures show a structure for mounting the outer wall panel (10) to the frame assembly. In Figure 5, (15)
Is a rectangular frame-shaped frame frame composed of a pair of left and right vertical frames (16) made of lip channel steel and upper and lower horizontal frames (17) also made of lip channel steel. 15) (15) ... are erected on a concrete foundation (18) side by side along the longitudinal direction thereof, and the outer wall panel (10) has its left and right ends in each frame frame ( 1
5) It is attached to the outer surface so that it is almost aligned with the end of (15).

At this time, as shown in FIG. 6, a band-like airtight sheet (19) having rubber or other airtightness is preliminarily attached over the outer surfaces of the frame frames (15) adjacent to each other. The end portions of the moisture-proof material (12) are pressed against the outer surface of the airtight sheet (19) so as to overlap each other and installed.

Reference numeral (21) is a metal fitting for fixing the outer wall panel (10), and as shown in FIG. 7, both ends of the main body (20) made of a short metal plate have different heights. Both of them are bent in a U shape, and one of the U-shaped portions (22) is brought into contact with the surface of the moisture-proof material (12) corresponding to the outer surface of the frame material (2) of the panel (10), and the other The U-shaped part (23) is brought into contact with the inner surface of the flange (24) of the vertical frame (16) of the frame frame (15), and the screw (25) inserted into the metal fitting body (20) from the indoor side, The frame member (2) is screwed and fixed. By this fixing, the airtight sheet (19) and the moistureproof material (12) are completely brought into close contact with each other to form an airtight layer penetrating substantially linearly in the wall surface direction.

[0017]

As described above, according to the present invention, the airtight material for closing the gap between the frames of the frame and the moistureproof material on the back surface of the outer wall panel are in close contact with each other to form a continuous airtight layer. Since the layers are arranged outside the framework, unlike the conventional case where they are provided on the inner wall side, there is no risk of being broken due to electrical wiring or equipment piping to the indoor side, and repair work for that is unnecessary. is there.

Further, it is possible to carry out the construction work by simply adhering the airtight material to the frame in advance and attaching the outer wall panel having the moistureproof material adhered to the back surface on the outer side thereof, and the construction work is very simple. Furthermore,
Since the airtight layer made of the moistureproof material and the airtight material penetrates in a substantially linear shape in the wall surface direction, the moistureproof and airtight performance is good.

Further, in the invention of claim 2 of this application, since the airtight material and the moistureproof material are both attached to the metal material such as the frame or the frame material, unlike the wood, the warp
It does not have the disadvantage of producing a gap due to drying shrinkage.

In addition, in the invention of claim 3 of this application,
Since the airtight material is a rubber having elasticity, when the moistureproof material is pressed, the airtightness is adhered while absorbing unevenness due to its elasticity, so that there is an advantage that the airtightness is further improved.
