Description

Description: TECHNICAL FIELD The present invention relates to a method for attaching a concrete outer wall panel to an outer peripheral side surface of a building by a dry method.

(Prior Art) A method of attaching an outer wall panel of a building by a dry method has been known.

(Problems to be Solved by the Invention) However, the conventional method of attaching the outer wall panels of this type has not been capable of sufficiently joining and fixing the panels. Therefore, over time, there is a risk that the assembly may come off due to misalignment, or that rainwater may enter the inside of the building.

Also, it is a mounting method using many kinds of mounting brackets,
There was a problem that the installation work was troublesome and the cost was high.

(Means for Solving the Problem) A method for mounting an outer wall panel of the present invention is a method for mounting an outer wall panel on an outer peripheral side surface of a building using a mounting bracket, and the outer wall panel is a rectangular plate made of concrete. Assuming that the shaped plate body is divided into two parts, the first half plate and the second half plate at the center of the plate thickness, the front half plate and the latter half plate are integrated by shifting to the position where the front half plate is in the opposite directions of the diagonal lines. The rear side of the rectangular plate body is formed with a rear projecting edge that projects the latter half plate more than the front half plate, and the other side surface has a front protrusion that projects the front half plate more than the latter half plate. An edge is formed, and a rising piece is formed on the upper surface of the rectangular plate body by projecting the latter half plate above the front half plate, and a hanging piece is formed on the lower surface by projecting the front half plate below the latter half plate. And a groove is formed along the rear surface of this hanging piece. The latter half plate after the groove is made as a small projection piece, and the mounting bracket is formed by bending one metal plate, and the left and right sides of the back plate are projected forward to form a leg plate. The front ends of the left and right leg plates are bent outwards to form elastic support plates, the lower part of the back plate projects forward to form support pieces, and the tips of these support pieces are vertically folded vertically. The upper and lower locking pieces are formed by bending and projecting forward from the supporting plate. A plurality of base plates stretched on the frame of the building are installed in consideration of the lateral dimension and vertical dimension of the outer wall panel. Each mounting bracket is installed, and the lower part of the lower panel, which is located at the bottom, is inserted into the upper locking piece of the lower mounting bracket that has the groove at the bottom, and the small projection piece is placed on the support piece. Of the upper mounting bracket (the same as the lower mounting bracket) placed above the lower mounting bracket. Supporting and fixing by inserting the rising piece between the plate and the lower locking piece, and the lower part of the upper outer wall panel that is connected to the lower outer wall panel, insert the groove into the upper locking piece of the upper mounting bracket. , By mounting the small projection piece on the support piece of the upper mounting bracket, the hanging piece of the upper outer wall panel and the rising piece of the lower outer wall panel are polymerized to sequentially attach multiple outer wall panels from bottom to top. The outer wall panels connected in the lateral direction overlap the rear projecting edge of one outer wall panel and the front projecting edge of the other outer wall panel.

(Operation) A large number of outer wall panels can be connected vertically and horizontally with one type of mounting bracket.

(Example) A method for attaching the outer wall panel of the present invention will be described based on an example shown in the drawings.

The outer wall panel 1 is a rectangular plate made of concrete.
Assuming that the rectangular plate body (outer wall panel) 1 is divided into a front half plate 11 and a rear half plate 12 at the center of the plate thickness, the front half plate 11 and the rear half plate 12 are in opposite directions of diagonal lines, 11 is formed integrally by shifting the position of the lower half plate 12 in the lower right direction and the rear half plate 12 in the upper left direction. On the upper surface of the rectangular plate body 1, a rear plate 12 is formed by projecting a rear half plate 12 upward from the front half plate 11.

A rear surface 110 of the hanging piece 11a forming the groove portion 13 is a vertical surface, and a front surface of the small projection piece 12c is a tapered surface 120 that is inclined so as to be gradually lowered rearward. Therefore, the cross section of the groove 13 has an inverted V shape with one side being vertical.

Further, a taper surface 12d is formed on the front surface of the rising piece 12a on the upper surface of the rectangular plate body 1 so as to be inclined so as to gradually rise rearward. Therefore, the rising piece 12a has a V-shaped cross section whose one side is vertical.

In addition, the upper surface 11c of the front half plate 11 is formed into a tapered surface whose front portion is gradually lowered to improve the rainwater flowability.

The dimensions of the outer wall panel 1 thus formed are, for example, 300 cm horizontally, 20 cm vertically, and 1.2 cm thick. The outer wall panel 1 is attached to the peripheral side surface of the building using the attachment fittings 2 (see FIGS. 3 to 5).

The mounting bracket 2 is formed by bending a single metal plate, and the left and right side portions of the back plate 21 are projected forward to form the leg plate 2
The front end of each of the left and right leg plates 22 and 22 is bent outward to form an elastic supporting plate 23 and 23, and the back plate 2
The lower part of 1 is projected forward to form a support piece 24.
The tip of 4 is bent vertically up and down to form upper and lower locking pieces 25, 26 projecting forward from the supporting plates 23, 23. The distance from the support plates 23, 23 to the upper and lower locking pieces 25, 26 is approximately equal to the plate thickness dimension of the rising piece 12a and the small projection 12c described above. Reference numeral 27 designates the mounting bracket 2 as the base plate (waterproof plywood) 3
It is an insertion hole of a fixing screw 4 fixed to.

Next, a method of mounting the outer wall panel 1 on the peripheral side surface of the building using the mounting bracket 2 configured as described above will be described.

A plurality of mounting brackets 2 are fixed (using fixing screws 4) to a base plate 3 stretched over a building frame 5. The fittings 2 are arranged in consideration of the lateral dimension and the vertical dimension of the outer wall panel 1, respectively, and especially, the connection of the outer wall panel 1 in the vertical direction (vertical direction) is sufficiently considered.

As the mounting method, the mounting of the outermost wall panel 1a located at the bottom and the outermost wall panel 1b connected on the outer wall panel 1a is exemplified (see FIG. 4).
