Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a building accessory panel comprising a molded body made of a hydraulic inorganic material and a frame material fixed to it for the purpose of construction. The present invention relates to a method for manufacturing a building accessory panel, which is characterized by excellent economic efficiency.

2. Description of the Related Art When constructing a building material such as a corner material using a hydraulic inorganic material, a frame material or the like for mounting on a pillar material or wall material of a building is attached to the back surface of the building material. Architectural accessory panels (hereinafter referred to as "feature panels")
It is widely practiced to build a frame and hook the frame material on the back surface onto a base material constructed on a pillar or a wall, or fix it with a bolt or the like.

Conventionally, as a method for producing such an accessory panel, a molded product made of a hydraulic inorganic material which has been completely cured by extrusion molding or press molding and then being naturally left to stand, steam curing, autoclave curing, etc. A frame material is fixed to the back surface of the molding (hereinafter referred to as "molded body") with an adhesive, a nail, a set screw, or the like.

[0004]

However, the above-mentioned prior art has the following problems. That is, since the frame is attached after the completely cured molded body is manufactured, it takes a lot of time and man-hours, resulting in high cost.

Further, since the molded body is often warped or bent at the time of molding, it is difficult to set dimensions and position when mounting the frame material. In addition, when bonding the molded body and the frame material, in addition to the complicated adhesion work in the bonding method, the initial adhesive strength of the adhesive is generally weak, so nails and setscrews must be used until sufficient adhesive strength is obtained. It is necessary to temporarily fix it with a temporary fastener, a heavy object, etc. Furthermore, since the force of peeling always acts due to the warp and the effective bonding area is small, the frame material is easily peeled from the molded body. Further, when mechanical means such as nails and setscrews is used, cracks and chips may occur due to attachment hole processing, nailing, screwing, and the like, which is particularly remarkable when the molded body has a warp. Furthermore,
There is also the problem that the head of nails and setscrews spoil the appearance.

Even after the accessory panel is manufactured and constructed,
Due to changes in humidity and temperature, "flaking" and local distortion of the molded product may occur, the frame material that adheres may peel off,
Stress may concentrate around the nail holes and screw holes, causing cracks.

The present invention has been made in view of the problems of the prior art as described above, and saves the labor and time of attaching a frame to a completely cured molded body, and an adhesive, a nail, a set screw, etc. The installation work can be done easily without using, and no cracking, chipping, peeling, etc. occur during and after the installation work, and the head of nails, setscrews, etc. does not spoil the aesthetics. The purpose is to provide a beautiful and economical accessory panel.

[0008]

In order to achieve the above object, a method of manufacturing a building accessory panel according to the present invention includes a frame material receiving groove formed in an upper surface of a tray. The step of placing the protrusions protruding on the upper surface upward, the step of extruding a molded product made of a hydraulic inorganic material and transferring the extruded product on the tray, the extruded product being transferred The tray is placed on the lower mold of the press mold, and the extrusion molded product is pressed from the upper surface by the upper mold of the press mold to perform press molding. And a step of forming a combined body of the press-formed product and the frame material by penetrating into the mold, and curing and curing while leaving the combined body on the tray.

The hydraulic inorganic material used in the present invention is mainly composed of cement such as Portland cement and alumina cement, gypsum, lime and the like, to which filler such as silica sand, pearlite, magnesium carbonate and calcium carbonate, and reinforcement. Alternatively, glass fibers, asbestos, wollastonite, metal fibers, inorganic fibers such as carbon fibers, organic synthetic fibers such as vinylon, polypropylene, polyester, and aramid fibers for the purpose of improving processability, pulp for the purpose of shape retention or thickening. ,
A mixture of cellulose, a pigment for coloring, etc., and water added thereto is generally used.

[0010]

[Operation] On the protrusions protruding from the upper surface of the frame material,
For an uncured extruded product made by extrusion molding a hydraulic inorganic material, transfer it to the lower mold of the press mold as it is, and press it with the upper mold so that it has a predetermined shape with multiple refracting surfaces At the same time as being molded into a press-molded product, the protrusions of the frame material bite into the uncured material and cure-harden in that state, so that the molded product can be molded without the use of adhesives, nails, or set screws. An accessory panel in which a frame material is firmly bonded to the back surface is obtained.

It is affixed in the state of being. The upper ends of the pressing plates 10a and 10b are rotatably coupled to the pressing portion 9a protruding from the central portion of the second upper mold 9.

On the other hand, the lower end portions of the pressing plates 10a and 10b are respectively connected via the links 12 to the pressing portion 8 of the first upper mold 8.

[0028]

As is apparent from the above description, according to the method for manufacturing an architectural accessory panel of the present invention, the accessory panel is manufactured by fixing the frame material at the same time as the production of the surface material (molded body). Therefore, as seen in the conventional building material panel manufacturing method, first, a cured molded body is manufactured, and then the back surface of the molded body is post-processed by using an adhesive, a nail, a set screw, or the like. There is no need to fix the frame material, and the man-hours, processing time, loss of raw materials, etc. for processing the panel are omitted, and the cost can be reduced.

Further, peeling, cracking, chipping and the like during the production unlike the case where the molded body and the frame material are joined by an adhesive, nails, setscrews, etc. do not occur. Further, the obtained building accessory panel is manufactured because the protrusions provided on the frame material do not easily come out by penetrating into the molded body, and therefore the surface material and the frame material are firmly bonded. Even if the molded body is distorted due to subsequent humidity changes or local temperature rise,
Since the molded body and the frame material are not peeled off, and there is no nail hole or screw hole, cracks due to stress concentration do not occur. Furthermore, the nails and setscrews do not spoil the appearance.
