Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for attaching concrete exterior wall panels to the outer peripheral side of a building using a dry method.

(Prior Art) A method of attaching exterior wall panels of a building using the dry method is known.

(Problem to be Solved by the Invention) However, the conventional method for attaching this type of exterior wall panel has not been able to sufficiently join and fix the panels together. Therefore, over time, there was a risk that the assembly would shift and come off, or that rainwater would enter the inside of the building.

In addition, the mounting method uses many types of mounting fittings, which causes problems such as troublesome mounting work and high cost.

(Means for Solving the Problems) The method for attaching an exterior wall panel of the present invention is to attach the exterior wall panel to the outer peripheral side of a building using mounting brackets, and the exterior wall panel is a rectangular plate made of concrete. If the shape plate is divided into two parts at the center of the plate thickness, the first half plate and the second half plate should be positioned in opposite diagonal directions (for example, the first half plate towards the lower right and the second half towards the upper left). The left side of the rectangular plate body has a rear protruding edge that protrudes the rear half plate to the left more than the front half plate, and the right side has a rear protruding edge that protrudes the rear half plate to the left side of the front half plate. A front protruding edge is formed that protrudes to the right than the plate, and a rising piece is formed on the upper surface of the rectangular plate that protrudes the rear half plate upwardly than the front half plate, and a raised piece that protrudes the rear half plate above the front half plate is formed on the bottom surface of the rectangular plate. A hanging piece is formed that protrudes further downward than the hanging piece, and a groove is formed along the rear surface of this hanging piece, and the rear plate behind this groove is a small protruding piece. It is formed by bending a metal plate, with the left and right sides of the back plate protruding forward to serve as leg plates.
The front ends of the left and right leg plates are bent outward to form elastic supporting plates, the lower part of the back plate is protruded forward to form a supporting piece, and the tip of this supporting piece is vertically bent up and down. It is made by bending to form upper and lower locking pieces that protrude forward from the above-mentioned support plate, and is attached to the base plate that is stretched to the framework of the building, taking into account the horizontal and vertical dimensions of the external wall panel. Multiple mounting brackets are installed, and the lower part of the lower exterior wall panel located at the bottom is
Insert the groove into the upper locking piece of the lower mounting bracket located at the lowest position, place the small projection piece on the support piece, and insert the upper part of the lower exterior wall panel into the upper locking piece located above the lower mounting bracket. The mounting bracket (same as the lower mounting bracket) is supported and fixed by inserting the rising piece between the support plate and the lower locking piece, and the lower part of the upper exterior wall panel connected to the top of the lower exterior wall panel is By inserting the groove into the upper locking piece of the upper mounting bracket and placing the small projection piece on the support piece of the upper mounting bracket, the hanging piece of the upper exterior wall panel and the rising piece of the lower exterior wall panel overlap. A plurality of exterior wall panels are sequentially attached from bottom to top, and each of the exterior wall panels that are connected in the lateral direction overlaps the rear edge of one exterior wall panel with the front edge of the other exterior wall panel.

(Function) Multiple exterior wall panels can be connected vertically, horizontally, and horizontally using one type of mounting bracket.

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

The outer wall panel 1 is a rectangular plate made of concrete. If this rectangular board (outer wall panel) ■ is divided into two at the center of the board thickness into the front half board 11 and the back half board 12, the front half board 11
and rear plate 12 in opposite diagonal directions (for example, front plate 1
1 toward the lower right, and the rear plate 12 toward the upper left. An upright piece 12a is formed on the upper surface of the rectangular plate body 1, and a rising piece 12a is formed on the upper surface of the rectangular plate 1, and a hanging piece 11a is formed on the lower surface of the rectangular plate body 1, and a hanging piece 11a is formed on the lower surface of the rectangular plate 1, causing the rear plate 12 to protrude above the front half plate 11. It is formed. A rear protruding edge 12b is formed on the left side of the rectangular plate body 1 so that the rear plate 12 projects further to the left than the front half plate 11, and on the right side, the rear protrusion 12b causes the front half plate 11 to protrude further to the right than the rear plate 12. A front protruding edge 11b is formed.

Note that a front protruding edge may be formed on the left side surface of the rectangular plate body 1, and a rear protruding edge may be formed on the right side surface.

A groove 13 is formed on the lower surface of the rectangular plate 1 along the rear surface of the hanging piece 11a.
is made into a small protrusion piece 12c.

The rear surface 110 of the hanging piece 11a constituting the groove 13 is a vertical surface, and the front surface of the small projection piece 12c is a tapered surface 120 that slopes gradually downward. Therefore, the cross section of the groove portion 13 has an inverted ■-shape with one side being vertical.

Note that the upper surface 11c of the front half plate 11 has a tapered surface that gradually lowers at the front to improve the flow of rainwater.

The dimensions of the outer wall panel l formed in this way are, for example, 300 cm in width, 20 cT11 in length, and 1.2 cm in thickness.
It is. The exterior wall panel 1 is attached to the peripheral side of a building using mounting brackets 2 (see FIGS. 3 to 5).

The mounting bracket 2 is formed by bending two metal plates, and the left and right sides of the back plate 21 protrude forward to form the leg plate 2.
2.22, and the front ends of the left and right leg plates 22.22 are respectively bent outward to form elastic support plates 23.23.
The lower part of the back plate 21 protrudes forward to form a support piece 24, and the tip of this support piece 24 is bent vertically up and down to form a top and bottom locking piece that protrudes ahead of the support plate 23.23. 25 and 26 are formed. Support plate 23.
The distance from 23 to the upper and lower locking pieces 25 and 26 is approximately equal to the thickness of the upright piece 12a and the small projection piece 12c. Reference numeral 27 indicates an insertion hole for a fixing screw 4 that fixes the mounting bracket 2 to the base plate (waterproof plywood) 3.

Next, a method of attaching the above-mentioned exterior wall panel 1 to the peripheral side of a building using the mounting bracket 2 configured as described above will be explained.

A plurality of mounting fittings 2 are fixed (using fixing screws 4) to a base plate 3 stretched over a framework 5 of a building.

The mounting brackets 2 are installed taking into consideration the horizontal and vertical dimensions of the exterior wall panel 1, but especially in the vertical direction of the exterior wall panel 1 (
Consider carefully the connections in the vertical direction.

As an example of the mounting method, mounting of the outer wall panel 1a located at the lowest position and the outer wall panel lb connected to the top of this outer wall panel 1a is illustrated (see FIG. 4).

The lower part of the outer wall panel 1a is attached to the lowermost mounting bracket 2.
It is supported and fixed to a. The groove 13 of the outer wall panel 1a is inserted into the upper locking piece 25 of the mounting bracket 2a, and the small projection piece 12c is placed on the support piece 24. On the other hand, the upper part of the outer wall panel 1a is supported and fixed to a mounting bracket 2b arranged above the mounting bracket 2a. The rising piece 12a of the outer wall panel 2b is inserted between the support plate 23, 23 and the lower locking piece 26 of the mounting bracket 2b.

Next, the outer wall panel 1 connected on top of this outer wall panel 1a
The lower part of b is supported and fixed to the mounting bracket 2b.

The upper locking piece 2 of the mounting bracket 2b connects the groove 13 of the outer wall panel 1b.
5 and place the small projection piece 12c on the support piece 24. In this state, the front surface of the rising piece 12a of the outer wall panel 1a is pressed with the rear surface 110 of the hanging piece 11a of the outer wall panel 1b. In other words, the upright piece 12a of the outer wall panel 1a is connected to the hanging piece 11a of the outer wall panel 1b and the supporting part 23.2 of the mounting bracket 2b.
3 and are clamped and fixed. At this time, approximately the same gap as the groove 13 described above is created between the rear surface 110 of the hanging piece 11a and the tapered surface 120 of the rising piece 12a.
The lower locking piece 26 of the mounting bracket 2b is fitted into this gap.

In this way, the exterior wall panels la, lb, . . . are successively connected and fixed upward to form the exterior wall of the building.

In addition, the connection of each exterior wall panel 1 in the lateral direction is, for example, between the rear projecting edge 12b of one exterior wall panel 1a and the other exterior wall panel l.
This is done by overlapping the front protruding edges 11b of a (see FIG. 5).

(Effects of the Invention) When the outer wall panels are connected in the vertical direction, the hanging pieces are superimposed on the upright pieces. The lateral connection of the exterior wall panel is such that the front edge overlaps the rear edge. Therefore, the external wall panels connected to each other can be sufficiently joined and fixed in the vertical and horizontal directions using the dry type 1 method.

Exterior wall panels placed anywhere can be mounted and fixed using one type of mounting bracket. Therefore, the manufacturing cost of the mounting bracket is low, it is easy to handle, and the installation work is also simplified.

In addition, at the joint between vertically connected external wall panels, the small protruding piece on the upper external wall panel and the rising piece on the lower external wall panel are connected by the vertical locking piece of the mounting bracket and the elastic support plate. It's being held in place. Therefore, the small projection piece and the upright piece inserted between the upper and lower locking pieces and the support plate are more strongly (fixed) by the elastic force of the support plate.
