Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer wall panel, and more particularly to an outer wall panel mounting device for realizing outer heat insulation.

[0002]

2. Description of the Related Art The outer heat insulating structure forms a heat insulating layer along the outer surface of the outer wall. In cold regions, the inner wall does not become thick even if the heat insulating layer on the outer side of the frame is thickened. , In areas that do not reduce the area of the room and require constant or long-term heating, use the heat capacity of the frame,
There is an advantage that the temperature change in the room can be reduced. Then, it is considered that the outer heat insulating wall is constructed by the dry method without increasing the number of construction steps on site by previously incorporating such a heat insulating layer for outer heat insulation into the outer wall panel.

Further, in a general outer wall panel not provided with an outer heat insulating layer, as shown in FIG. 8, in the joint gap between the outer wall panels (32) arranged outside the frame (31), the frame frame is formed. The flange (33) is fixed with the metal fitting (34).

[0004]

When the outer wall panel incorporating the outer heat insulating layer as described above is attached to the outside of the frame,
With respect to the framework arranged along the reference line of the building, the thickness of the heat insulating layer causes the outer surface of the panel to project outward. Therefore, the fixing method as shown in FIG. 8 has a disadvantage that the joint gap becomes deep and the fixing work becomes difficult. Further, in the case of a small land, the gap between the adjacent buildings becomes small, which also has a drawback that work from the outside becomes difficult in this sense as well.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the conventional drawbacks described above and to provide a mounting device for an outer wall panel which can be mounted on the outer wall panel to the frame assembly from the indoor side. To do.

[0006]

In order to solve the above problems, the present invention provides a mounting device for mounting an outer wall panel having a frame and an outer wall plate mounted on the outside of the frame to a frame. In addition, the wall surface direction flange of the frame frame is directly or indirectly overlapped with the wall surface direction flange outer surface of the frame assembly, and the other end of the metal fitting having one end abutting the flange inner surface of the frame assembly is exposed to the indoor side. It is characterized in that it is fixed to the flange of the frame with a screw inserted from.

[0007] Similarly, in the invention of claim 2 of this application, in the above, the fixing metal member has a pair of abutting portions formed by bending both ends of a main body made of a metal plate to the same side in a U-shape. The contact piece at the tip of one of the contact portions contacts the inner surface of the flange of the shaft assembly, and the contact piece at the tip of the other contact portion is fixed to the flange of the frame by the screw. Characterize.

In the invention of claim 3 of this application, in the above description, the flange of the frame is an inner flange of channel steel, and the inner flange is superposed on the outer surface of the flange of the shaft assembly. What is characterized is provided.

In the above, it is conceivable to attach a moisture-proof sheet to the indoor side surface of the outer wall panel.

[0010]

As described above, since the flanges of the frame of the outer wall panel and the flanges of the shaft assembly are overlapped with each other and fixed with the screws by the fixing metal fittings, the fixing work can be performed from the outside through the joint gap as in the conventional case. It does not need to be carried out and can be easily fixed from the inside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an outer heat insulating panel which is an outer wall panel of the present invention, in a state before being filled with a 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 and the following figures show a state in which a space surrounded by the frame (1) and the outer wall plate (5) is filled with a heat insulating material (8). 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 FIG. 4, the boundary between the heat insulating material (8) and the outer wall plate (5) is recessed in the heat insulating material (8) and penetrates the panel (10) in the vertical direction. A strip air layer (11) is formed.

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, covers the frame (1) and the heat insulating material (8). Like this
A moisture barrier (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 heat insulating panel (10) on the frame using the fixing metal fitting of the present invention. In FIG. 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. , These frame frames (15) (15) ... are erected side by side on the concrete foundation (18) along the longitudinal direction thereof, and the heat insulation panel (10) has its left and right end portions. However, they are attached to the outer side surfaces of the frame frames (15) and (15) so that they substantially coincide with the ends thereof.

At this time, the frame frames (1
A band-shaped airtight sheet (19) having rubber or other airtightness is previously attached across the outer surface of (5), and the moistureproof material (12) is attached to the outer surface of the airtight sheet (19). The ends are pressed against each other so that they overlap each other.

Reference numeral (21) is a fixing metal fitting of the present invention for fixing the heat insulating panel (10), and as shown in FIG. 7, both ends of the main body (20) made of a short metal plate are raised. The surface of the moisture-proof material (12) corresponding to the outer surface of the frame material (2) of the panel (10), the U-shaped portion (22) of which is bent together so that Abut
The other 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 is attached. The screw is fixed to the frame member (2) by screwing. In this case, a screw hole (27) is formed in the abutment piece (26) on the side of the frame material (2), and the main body (20) is fitted to the screw hole (27) from the head of the screw (25). Large insertion hole (2
8) is formed, and the entire screw (25) is inserted inward from the insertion hole (28) to directly tighten the contact piece (26) and the frame member (2). However, a method in which the head of the screw (25) is brought into contact with the outside of the main body (20) and tightened is also conceivable. Although the moistureproof material (12) on the back surface of the heat insulation panel (10) is pierced by screwing in the screws (25), since the frame material (2) and the contact piece (26) are closely attached to each other, There is no need to repair to maintain airtightness.

[0017]

As described above, according to the present invention, the flange of the frame and the flange of the frame on the inner side of the outer wall panel are overlapped with each other, and are fixed from the inner side with the screws via the fixing metal fittings that are installed across the both. Therefore, unlike the conventional case, it is not necessary to perform fixing work from the outside through the joint gap, and the fixing can be easily performed from the inside. Therefore, the effect of facilitating the mounting work can be obtained even in the case of a small land with a narrow gap between adjacent buildings or a panel provided with an outer heat insulating layer.

Further, in the invention of claim 4 of this application, the screw is screwed through the moisture-proof material. However, the periphery of the hole of the moisture-proof material opened by the screw is set inside and outside by the tightening force of the screw. Because it is sealed with a flange,
There is almost no risk of impairing the airtightness, and the effect of eliminating the need for repair work is obtained.
