Description

Description: TECHNICAL FIELD The present invention relates to a method for manufacturing an outer wall panel unit made of a relatively heavy finishing material such as stone, glass, or large tile.

[Conventional technology]

In recent years, in many outer wall curtain walls, relatively heavy materials such as marble and large tiles are used as finishing materials.

Most of this type of outer wall curtain wall is formed by adhering a finishing material such as marble or large tile to the outside of the PC board to form an outer wall panel of a certain size, and bolting this outer wall panel to the structure of the building. It is composed by doing.

[Problems to be Solved by the Invention]

However, in such an outer wall structure, since the finishing material is only a heavy material, handling such as transportation and installation is not only troublesome, but also dangerous.

Also, depending on the finishing material adhered to the surface of the PC board, PC
Some plates have a significantly different coefficient of thermal expansion from the finish,
For this reason, when the PC plate and the finishing material expand under the heat of the sun, the entire panel may be warped, the finishing material may be cracked, or peeled off.

In addition, since the PC board and the finishing material are integrally molded, partial repair cannot be done at all if the finishing material is partially damaged or the finished color or pattern does not match,
It will be necessary to replace it entirely.

Furthermore, this type of exterior panel is manufactured by the so-called tile form pre-installation method or tile pre-precast reinforced concrete construction method, but since both methods are wet construction methods, it requires a long period of time to cure the concrete after placing it. Not only is the manufacturing period unavoidable extended, but
It is necessary to secure a particularly large stockyard for curing.

This invention was developed in order to solve the above-mentioned conventional problems, and it is possible to improve the workability by improving the weight of the outer wall panel and the earthquake resistance of the building, and to warp the panel due to thermal expansion. An outer wall structure that can almost completely prevent cracking and peeling of the finishing material, can be manufactured in a short period of time, and can also partially repair and replace the finishing material after manufacturing. It is intended to provide.

[Means for solving the problem]

A method of manufacturing an outer wall panel unit according to the present invention,
Unlike conventional outer wall panels, it is not a single PC board that is integrally molded with multiple finishing materials, but instead of the PC board, a lattice frame with a waterproof plate and bolt holes is used. A plurality of finishing materials are continuously attached to the lattice frame-like frame through a special attachment fitting to form a single outer wall panel unit.

That is, according to the present invention, (A) a finishing material having fitting grooves on the upper, lower, or left and right end surfaces, and (B) a mounting bracket having a substantially groove-shaped cross section and a plurality of mounting bolts standing upright on one flange A plurality of finishing materials with mounting fittings, which are mounted by fitting the other flange of the metal fittings into the fitting grooves of the finishing material, are laid side by side vertically and horizontally on the bed (C) with the finishing surface facing down, (D) ) A lattice frame-shaped frame with a waterproof plate and bolt holes is placed thereon while inserting the mounting bolts into the bolt holes of the lattice frame-shaped frame and tightened with nuts.

〔Example〕

Hereinafter, a method for manufacturing an outer wall panel unit according to the present invention will be described with reference to an illustrated embodiment.

(1) Since the finishing material 1 is made of stone, glass, large tiles, or the like because of its heavy material, it is formed into a rectangular plate shape that can be easily carried by one person, and has a predetermined depth on the top and bottom or left and right end faces or the entire circumference. Fitting grooves 4 and 4 are provided.

The mounting member 2 has a substantially groove-shaped cross section and is formed to have a length substantially equal to one side of the finishing material 1, and stopper pieces 7, 7 are attached to both ends thereof. Mounting bolts 6, 6 are mounted upright on both ends of one flange of the mounting bracket 2.
(The mounting bracket 2 is easily manufactured by bending a steel plate and welding the mounting bolts 6 and 6.)
The other flange serves as a fitting piece 5 that fits into the fitting groove 4 of the finishing material 1. The mounting brackets 2 having such a shape are attached to the upper and lower end surfaces or the left and right end surfaces of the respective finishing materials 1 via the fitting pieces 5, and a large number of finishing materials 1 with the mounting brackets 2 are prepared. If the fitting groove 4 is provided on the entire circumference of the finishing material 1, the mounting member 2 can be mounted in the desired direction of the finishing material 1. (Refer to Fig. 5) (2) On the other hand, the lightweight H-section steel and the channel steel are assembled in a grid pattern,
A frame 8 is prepared in which a waterproof plate 9 made of a thin metal plate is attached to the surface on which the finishing material 1 is attached by welding or the like, and a plurality of bolt holes 10 are drilled at predetermined positions of the flange of the frame material. (See Fig. 4) (3) Finishing material 1 with mounting bracket 2 on bed 3
.. A plurality of (...
(9 pieces in the example in the figure).

On top of that, attach a piece of frame 8 to the mounting bolts 6, 6 ...
・ Mount the bolt while inserting it into the bolt holes 10, 10 ... of the frame 8, and fix the nuts at the tips of the mounting bolts 6, 6.
Fitting 11, 11, ...
The attached finishing materials 1, 1 ... Are fixed to one frame 8. (See FIG. 4) When tightening the fixing nut 11, a packing 12 is interposed (see FIGS. 1 and 2) to prevent rainwater from entering through the bolt hole 10. In addition, a sealing material is filled in a gap between the adjacent finishing materials 1 to prevent rainwater from entering from this portion. (Refer to FIG. 2) By the above work, the manufacture of one outer wall panel unit A is completed.

The manufactured outer wall panel unit A is attached to the tip ends of the upper and lower slabs 15, 15 by a plurality of fasteners 16, 16 like an ordinary outer wall panel to form an outer wall. (6th
(See the figure) When installing the outer wall panel unit A in a building, double sealants 17 and 18 are installed in the gaps between the upper and lower outer wall panel units A to prevent rainwater from entering from this part. (Refer to FIG. 2) [Advantages of the Invention] Since the present invention is configured as described above, it has the following advantages.

(1) Since the outer wall panel unit is configured by bolting the finishing material to the frame through the mounting metal fittings, the weight of the outer wall, and thus the weight of the entire building can be significantly reduced.

(2) Since each finishing material is individually attached to the frame, it can be individually removed even after the attachment, and the partial repair and replacement of the finishing material can be easily performed.
It is possible to adjust the color and pattern of the finished surface again at the installation site.

(3) There is no concern that the panel unit will be warped due to thermal expansion, and that the finish material will not be cracked or peeled off.

(4) Since the waterproof plate is attached to the entire surface of the frame to prevent the infiltration of rainwater, it is not necessary to intentionally fill the gap between the finishing materials with the joint member.

(5) Since the outer wall panel unit is not manufactured by the wet method of concrete, it does not require a curing period as in the conventional method, and can be manufactured in a much shorter period. Moreover, since it can be shipped immediately after manufacturing, it is not necessary to secure a large stockyard.
