Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall panel made of glass or the like.

[0002]

2. Description of the Related Art Conventionally, a wall panel such as a glass panel as shown in FIG. 3 which is a perspective view has been known. That is, the elongated sealing member 14 made of aluminum is adhered to the back surface edge of the plate-like member 11 such as glass with the silicone sealant 13. Further, a wall panel in which an aluminum mounting member is bonded with a thermosetting silicone rubber adhesive is also known. This wall panel is constructed by engaging an aluminum mounting member with a building through a metal engaging member.

However, the thus constructed product has the following problems. That is, these methods using the thermosetting silicone rubber adhesive are epoch-making in terms of adhesion reliability, productivity improvement, curing time, and reduction of the curing space. Since the adhesive is thermally vulcanized at a temperature of about 90 to 130 ° C., internal stress is generated due to the difference in coefficient of thermal expansion between aluminum and glass, and the glass is deformed. This deformation causes a problem that the reflected image is distorted. Particularly in the case of using heat ray reflective glass, it is extremely important to obtain a good reflected image.

In order to suppress the deformation of the glass, it is conceivable to increase the thickness of the glass, but increasing the thickness causes an increase in cost. As another method, it is conceivable to reduce the size of the glass, but if this method is adopted, there will be great restrictions on the design.

[0005]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, and makes it possible to reduce the size of a plate member such as glass without increasing the plate thickness of the plate member such as glass. An object of the present invention is to provide a wall panel that can obtain a good reflection image when constructed without shortening.

[0006]

DISCLOSURE OF THE INVENTION The present invention is a wall in which an elongated aluminum mounting member having a π-shaped cross section is bonded to the back edge of a plate member such as glass with a thermosetting silicone rubber adhesive. In the panel, there is provided a wall panel in which an aluminum mounting member is divided into a plurality of pieces in the longitudinal direction.

The present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a wall panel according to the present invention. In FIG. 1, the plate member 11 constitutes an outer wall of a building, and is formed of glass, ceramics, metal or the like to form an image on the outer surface by reflection. Among them, glass, particularly heat ray reflective glass having the heat ray reflective layer 12 on the back surface is effective. However, the heat ray reflective layer 12 may be provided on the surface or both the front and back sides. In addition, the plate-shaped member 11
Is not limited to a single plate, and may be laminated glass or multi-layer glass. Further, the size thereof is large, for example, the length of the edge portion to which the aluminum mounting member 14 is bonded is 1
Those having a thickness of more than 000 mm are effective.

An aluminum mounting member 14 is bonded to the edge portion of the back surface of the plate member 11 with a thermosetting silicone rubber adhesive 13. The aluminum mounting member 14 is divided into a plurality of pieces in the longitudinal direction. If the length d of the aluminum mounting member 14 is too long, the distortion of the reflected image occurs, and if it is too short, the productivity of the wall panel decreases, which is not preferable. This length d is the plate-shaped member 1
1 varies depending on the material and thickness. For example, when the plate member 11 is glass and the thickness thereof is about 8 to 19 mm, d is preferably in the range of 100 to 800 mm.

The aluminum mounting member 14 may have any width as long as the wall panel can withstand the wind pressure, and specifically, it is about 10 to 30 mm.

Although the thermosetting silicone rubber adhesive 13 is not divided in the length direction in FIG. 1, it may be divided into the same length d as the aluminum mounting member 14.

As the thermosetting silicone rubber adhesive 13, self-adhesive type silicone rubber is used to directly bond the plate-shaped member 11 and the aluminum mounting member 14 together with the plate-shaped member 11 or the aluminum in advance. The thermosetting silicone rubber adhesive 13 is adhered to one of the attachment members 14 and the other thermosetting silicone rubber adhesive 13 is attached.
You may adhere this by. Alternatively, after co-extruding the aluminum mounting member and the thermosetting silicone rubber adhesive, and integrally bonding with the aluminum mounting member,
This may be adhered to the plate-like member 11 using a thermosetting silicone rubber adhesive.

If the thickness of the thermosetting silicone rubber adhesive 13, that is, the distance between the plate member 11 and the aluminum mounting member 14 is too thin, the distortion of the reflected image is likely to occur, and if it is too thick, the cost increases. Therefore, both are not preferable. The thickness of the thermosetting silicone rubber adhesive 13 is preferably in the range of 8 to 20 mm.

In manufacturing such a wall panel, an aluminum mounting member 14 having a predetermined length d is prepared, and the plate member 11 is bonded with a thermosetting silicone rubber adhesive 13.
A mounting member 14 made of aluminum, which is longer than d, may be adhered to the thermosetting silicone rubber adhesive 1
After adhering to the plate-like member 11 by 3, it may be cut into a predetermined length.

In the wall panel according to the present invention, as shown in FIG. 2 which is a side view, a metal engaging member 15 is engaged with two symmetrical grooves formed in the aluminum mounting member 14, Construction is performed by attaching this engaging member to a building.

[0015]

[Example] Length 1500 mm, width 1000 mm, thickness 8
A heat ray reflective layer was formed on a soda-lime-silica glass of mm to prepare the heat ray reflective glass. An aluminum mounting member having a width of 40 mm and a length of 1500 mm was bonded to the edge portion of the heat ray reflective glass in the lengthwise direction using a thermosetting silicone rubber adhesive to manufacture a wall panel. When bonding, attach the aluminum mounting member with a die to a thickness of 12 mm.
The thermosetting silicone rubber adhesive prepared in step 1 was coextruded and integrated. Then, this was heated at 300 ° C. for 3 minutes to vulcanize the silicone rubber adhesive to obtain an integrated product with an aluminum mounting member.

Then, the integrated product and the heat ray reflective glass are pressure-bonded to each other via a thermosetting silicone rubber adhesive dispensed to a thickness of 2 mm and kept at 120 ° C. for 60 minutes to cure the wall panel. It was made.

This wall panel was fixed with an aluminum mounting member so that the length direction was vertical, and the distortion of the reflected image of the fixed wall panel was measured as follows.

20 at a distance of 40 m from the surface of the wall panel (the surface to which the aluminum mounting member is not adhered).
The reflection image reflected on the glass surface was measured from the surface of the grit board while standing upright against a grit board on which a grid of 0 mm square was drawn. As a result, in the reflected image, the lines forming the lattice were distorted so as to be curved curves outward at the peripheral edge. The number of lattices was 19 in the vertical direction. In addition, when the wall panel is not distorted, as a reflection image,
The lines forming the grid are straight lines, and the number of grids is 15 in the vertical direction.

Next, the mounting members made of aluminum (both of them) were cut at the central portion to have a length of about 750 mm,
Similar measurements were made. As a result, the linearity of the grid was ensured as the reflected image, and the number of grids was 15.8 in the vertical direction.

Further, the aluminum mounting members (all four) were cut and the length thereof was set to about 375 mm, and the same measurement was performed. As a result, as the reflected image, the linearity of the grating was further improved, and the number of gratings was 15.5 in the vertical direction.

[0021]

According to the wall panel of the present invention, the aluminum mounting member is divided, and the plate member is not deformed due to the difference in thermal expansion coefficient between the aluminum mounting member and the plate member. After that, even if the size of the plate-shaped member is large, it is possible to obtain the one in which the distortion of the reflected image is small without increasing the thickness.
