Description

[Detailed Description of the Invention] This invention relates to a frame body that is attached by adhesive or the like to the periphery of an outer wall panel whose outer periphery is a rectangular shape other than a rectangular shape.

As shown in the cross section in FIG. 1, the exterior wall panel is generally made by filling a foam insulation material 3 such as urethane, expanded polystyrene, or phenol resin between two hardboards 1 and 20, and filling the outer hardboard 10 surface with a foamed heat insulating material 3. A structure in which an aluminum plate 4 is attached and a coating 5 is applied to the surface of the aluminum plate is used.

The frame body has a U-shaped cross section with rising pieces 6 and 7 as adhesive surfaces to be bonded to the inner surfaces of the peripheral parts of the hardboards 1 and 2, and in particular, the lengths of the rising pieces 6 and 7 on both sides are Different modified U-shaped frames are used.

This frame connects the exterior wall panel to the building's steel frame (C
channel), etc.

By the way, since such a frame is glued to a local part of the outer wall panel as described above, its shape in plan view needs to be the same as the outer periphery of the outer wall panel, but the conventional frame is shown in Fig. 2. As shown in the figure, the vertical frame 8゜9 and the horizontal frames io and i1, which are cut according to the vertical and horizontal dimensions of the external wall panel, are welded together at their ends to form the outer peripheral shape of the external wall panel. have shortcomings.

In the same figure, the vertical frames 8 and 9 and the horizontal frame 10°11 are a, b tc.
, d are joined because the frame body itself does not require much strength and the material can be saved by the amount of the notches.

First of all, the disadvantages are that it is necessary to cut vertical frames and horizontal frames of various sizes according to external wall panels of different sizes, and when assembling, two vertical frames and two horizontal frames must be cut end to end. Since we have to weld a total of 4 places, cutting work,
There is a drawback in that the assembly work is extremely time consuming.

Second, since the joints between the vertical and horizontal frames are welded, build-up may occur, which has a structural disadvantage in that when it is glued to the exterior wall panel, the hardboard located at the welded area will float up. be.

Thirdly, each corner of the frame has notches a, b,
Because of the presence of c and d, the panel corners located in those areas, specifically the hardboard corners, may come into contact with other objects during transportation or transportation, resulting in damage, resulting in a decrease in product value. There are disadvantages such as coming.

Therefore, the present invention aims to provide a new and useful means that can drastically reduce such drawbacks.

In order to achieve such a purpose, the frame of the exterior wall panel according to the present invention has two U-shaped frames, which is half that of the conventional one, and each U-shaped frame is bent. Therefore, there are only two integration points that require welding, etc., at both ends of the U-shaped frame.

In addition, in order to protect the hardboard corners from damage due to contact with other objects, deliberate cuts are formed in the rising pieces located at the bends.

Next, one embodiment of the present invention will be described based on the drawings.

In FIG. 3, reference numeral 12 denotes a frame of an external wall panel, which is made up of, for example, modified U-shaped frames 13 and 14 as two U-shaped frames.
, 13b, 14a, and 14b are joined by welding W or the like.

Before each U-shaped frame 13, 14 is bent,
As shown in FIG.
16 Cut in the shape of a slanted dogleg or L-shape 1
7 and 18 are formed.

Here, the shape of a slanted "dog" or "L" literally refers to the shape of a hiragana "<" character or a Roman character "L" rotated by a predetermined angle.

The reason for forming the cut in such a shape is that when the frames 13 and 14 are bent with the cut position at the top, the rising piece 15
．． 'f6 cut side edge 15a.

This is to ensure that 16a is present at the bent corner.

In this case, it is desirable that the angles θ1 and θ2 formed by the cuts 17 and 18 and the upper edges of the rising pieces 15 and 16 coincide with the bent corners of the frames 13 and 14, respectively.

That is, in the illustrated example, one U-shaped frame 13 is bent at a right angle, so 01 is a right angle, and the other U-shaped frame 14 is bent at an obtuse angle. It is desirable that θ2 be the same obtuse angle.

In addition, the reference dimensions for forming the cuts 17 and 18 are as follows: 11=28gi, A=19ho,
l 215 h, 14=3 10 mm, and 11. , =6mm, 16 =4
It is mm.

However, the height hl of the rising piece 15 is 29 mm, and the height hl of the rising piece 16 is 29 mm.
The height h2 is set to 20 mm.

Further, the position in the longitudinal direction of the U-shaped frame at which each cut is formed is determined from the outer circumferential dimension of the outer wall panel.

The frame for the exterior wall panel having this configuration can be manufactured by the following procedure.

That is, first, a metal strip-shaped plate wound into a roll is unrolled and cut into an appropriate length.

After forming the above-mentioned cuts in the portions corresponding to the rising pieces on both sides of each cut band-shaped plate body, the rising pieces are made to stand up by pressing or the like.

Next, the band-shaped plate formed as a U-shaped frame in this manner is bent with the cut position as the top, and finally the ends of the two frames are joined by welding or the like.

Since the frame of the exterior wall panel according to the present invention is constructed as described above, it exhibits the following effects.

■ Since the proposed frame consists of two U-shaped frames, cutting work and joining work such as welding can be halved compared to conventional frames.

In this case, the proposed frame requires the additional work of bending the U-shaped frame, but this work can be done automatically by the vendor.

Therefore, when looking at the entire manufacturing operation, the frame of the present invention has better workability and can be manufactured with higher efficiency than the conventional frame.

■ Also, since the welding point is at 2 o'clock, there is less lifting of the corner of the outer wall panel due to build-up compared to conventional frames, and since there are only 2 build-ups, grinding It can be resolved quickly.

■ The cuts formed on the rising pieces on both sides of the U-shaped frame are in the shape of a slanted V-shape or L-shape, so if the frame is bent with the cut position at the top, the corners of the frame will rise. The cut edge of the piece is present.

Therefore, if the proposed frame is glued to the periphery of the outer wall panel, one of the rising edges will be located at the corner of the hardboard of the panel, and the corner of the hardboard can be protected from damage due to contact. .

Therefore, it is possible to improve the product value of exterior wall panels and to significantly reduce the occurrence of defective products.

■ Conventional frames have all corners joined by welding, so the vertical and horizontal frames must overlap somewhat at each corner, but the proposed frame has only two corners that are U-shaped. All you have to do is polymerize the frame.

Further savings can therefore be made in the portioned material which does not need to be polymerized at the other two corners.

The shape of the frame of the outer wall panel in plan view is determined by the outer peripheral shape of the outer wall panel, so the shape of the frame in plan view according to the present invention is not limited to the shape shown in the examples. Of course.
