Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a construction panel comprising a cementitious reinforcing layer, a porous heat insulating layer, and a water-resistant decorative surface layer.

(Conventional technology) As a construction panel that is lightweight and has excellent insulation properties,
Inorganic panels such as rock wool boards, glass wool boards, hydrated calcium silicate boards, and organic panels such as foamed synthetic resin boards are commonly used.
All such architectural panels have insufficient strength. For this reason, a composite panel has also been proposed in which a surface layer made of cement is formed on one side of a foamed plastic board with excellent heat insulation properties. (For example, Japanese Utility Model Application Publication No. 53-38112) (Problems to be solved by the invention) However, even the conventional composite panels for construction as mentioned above have insufficient surface strength and bending strength, and are not water resistant. Even if used as an interior or exterior material, it would have poor durability, and the surface layer made of cement would have a poor decorative effect.

(Means for solving the problems) The present invention solves the above problems and improves strength and
Architectural panels that have excellent water resistance, heat insulation, and fire resistance, and are also decorative, and can be installed accurately and easily on walls, and can be used as interior or exterior materials for buildings. It was completed for this purpose, and a water-resistant decorative layer was formed on the main surface of the shallow box-shaped panel made of cement, with the peripheral frame integrally molded on the back of the main plate in which reinforcing metal was embedded. A porous, lightweight core plate is integrally buried in the recess of the frame, and a distal end of a mounting bracket whose base end is fixed to the reinforcing metal protrudes from the peripheral frame.

(Function) When such architectural panels are installed on a wall using mounting brackets during interior or exterior construction of a building, the main body of the panel is made of cement and formed into a shallow box shape. In addition, reinforcing metal is embedded in the main panel, so it has excellent surface strength and bending strength, as well as fire resistance.Also, the main panel is made of cement with a high specific gravity. Despite the fact that it has a recess formed on its back surface, the specific gravity of the porous lightweight core board that is embedded and integrated into this recess is small, making it lightweight and convenient to handle as a whole, as well as having good heat and sound insulation properties. Excellent. Furthermore, since a water-resistant decorative layer is formed on the main surface of the panel, it can provide an excellent decorative effect simply by attaching it to the wall using the mounting hardware, and it also does not absorb water, which is a drawback of cement. Moreover, the base end of the mounting bracket is fixed to the reinforcing metal embedded in the main plate of the panel, and the tip protrudes from the surrounding frame, so it has excellent strength and reduces weight during long-term use. There is no fear that the main body of the large panel will fall from the wall surface.

(Embodiment) Next, the present invention will be explained in detail with reference to the illustrated embodiment.
The main body of the panel is made of cement such as cement mortar or gypsum plaster and has a recess 2 of 850 mm x 850 mm x 85 mm formed on the back side. A reinforcing metal 3 is integrally embedded by stretching iron vertically and horizontally or by stretching a metal mesh such as a metal lath plate, and a peripheral frame part 1b is integral with the main plate part 1a of the panel main body 1. There is a long bolt-shaped mounting bracket 4 near the corner of
The base end thereof is fixed to the reinforcing metal 3 by means such as welding and protrudes from the reinforcing metal 3. Further, a porous lightweight core plate 5 is integrally embedded in the recess 2 on the back surface of the panel main body 1, and a water-resistant decorative layer 6 is formed on the surface of the main plate portion 1a. Note that the porous lightweight core board 5 may be an inorganic board such as a rock wool board, a glass wool board, a calcium silicate board, a foam glass molded board, a pumice-like foam board, or an organic board such as a foamed synthetic resin board. However, if it is an inorganic board, it will have excellent fire resistance, and even if the water-resistant decorative layer 6 is a synthetic resin coating layer such as polyurethane paint, it cannot be used as a tile or light metal thin plate. It may also be an adhesive layer such as. Furthermore, the recess 2 of the shallow box-shaped panel main body 1 may be partitioned by vertical and horizontal partition walls made of the same material, and the mounting brackets 4 may also be attached to these partition walls.
Furthermore, for exterior use in places where rainwater is likely to permeate, a plastic water-resistant coating may be applied to the porous lightweight core plate 5 on the front and back surfaces of the peripheral frame portion 1b, or a spray coating such as water-resistant cement may be applied. It will be even more effective if you apply it first.

With this structure, construction is easy because the tip of the mounting bracket 4 protrudes from the back surface during interior or exterior construction of a building, and it can be fixed to the wall using the mounting bracket 4. Furthermore, even if a tensile force is applied to the main plate part 1a of the panel body 1, which has a large weight, in a direction that causes it to peel off due to its own weight after construction, the mounting bracket 4 will not fit with the reinforcing metal embedded in the main plate part 1a. Since the base end is fixed to 3, the holding force is excellent and there is no possibility that the panel main body 1 will peel off and fall from the wall surface. Therefore, in order to manufacture such architectural panels, for example, a mortar material is prepared by mixing 2000 g of white cement, 4000 g of white silica sand of 60 meshes, and 2 g of Metrose with 2000 c.c. of water. Inner diameter is 900mm x 900mm x
Prepare a mold with a 100mm wooden frame placed on a resin board and seal the joints. Decorative tiles are laid out in this mold, some of the mortar material mentioned above is poured in, and an 880mm x 880mm metal lath board is placed on top of the mold. near the corner of
A reinforcing member made by welding 150 mm long bolts with their base ends was laid down, and the remaining mortar material was poured over it. Next, a commercially available water-repellent Rockwool board measuring 850 mm x 850 mm x 85 mm was placed. Place a weight on the center of the back side of the mortar material in the wooden frame, and place a weight on the center of the glass wool board via a push plate until the mortar material is pushed up to the shoulder of the side, leave it for 24 hours to harden, and then remove the wooden frame. Remove, humidity 95% to 100
% for 24 hours, then leave it indoors and dry it.

(Effects of the invention) As is clear from the above description, the present invention is mainly a shallow box-shaped panel formed with cement and reinforcing metal embedded inside to improve surface strength, bending strength, and fire resistance. At the same time, a porous lightweight core board is embedded in the recess to ensure weight reduction, heat insulation, and soundproofing.Furthermore, a water-resistant decorative layer is formed on the surface of the main panel to ensure that there is no difference after installation. It is designed to exhibit sufficient water resistance and a decorative effect without any post-processing, and can be mounted on a wall using a mounting bracket that protrudes from the surrounding frame with the base end fixed to the reinforcing metal. It is not only easy to install, but also prevents the panel from peeling off and falling over a long period of time.It has a simple structure and can be mass-produced at a low cost, making it a solution to the problems of conventional architectural panels. It has extremely great practical value.
