Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an exterior wall panel used for the exterior wall of a building, etc., and a method for manufacturing the same.

(Prior Art) Conventionally, ALC boards have been known as this type of exterior wall panel.

(Problems to be Solved by the Invention) However, since the ALC board is made of homogeneous foamed lightweight concrete, although it is lightweight, it also has problems with surface hardness, durability, water absorption, etc. However, since autoclave curing is carried out during its production, it is inconvenient that it is not possible to produce products with very large dimensions.

(Means for Solving the Problems) The first invention of the present application aims to provide an exterior wall panel that eliminates the above-mentioned conventional disadvantages, and is made of a cementitious composition formed into a plate-like body. In the exterior wall panel, porous reinforcing plates are arranged facing each other along both the front and back sides of the plate-like body, and the inner area partitioned by these porous reinforcing plates is filled with foamed lightweight aggregate. do.

The second and third inventions of the present application aim to provide a simple method for manufacturing an exterior wall panel that eliminates the above-mentioned conventional disadvantages, and the second invention is directed to a mold having a space for forming a plate-shaped body. In a frame, porous reinforcing plates each having a plurality of vertically inclined inclined holes each having a filling space of foamed lightweight aggregate are arranged facing each other so that the lower ends of the inclined holes are oriented toward the filling space; Next, while flowing the fluid cementitious composition into the filling space together with the foamed lightweight aggregate, the fluid cementitious composition is spread throughout the entire area of the formwork through the inclined holes, and then the fluid cementitious composition is introduced into the filling space. It consists of solidifying the composition.

Further, the third invention provides a porous reinforcing plate in which a large number of vertically slanted holes are formed in a formwork having a space for forming a plate-like body, and a space for filling the lightweight foamed aggregate. The inclined holes are arranged so as to face each other so that the lower ends thereof face the filling space, and then the filling space is filled with foamed lightweight aggregate, and then a flowable cementitious composition is poured into the entirety of the formwork. Consists of solidification.

(Examples) Examples of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an example of the implementation of the exterior wall panel of the first invention of the present application, in which 1 is a plate-shaped body 2 with a thickness of about 10 cm formed of a cementitious composition such as Polmyland cement. In the inside of the plate-like body 2, a large number of inclined holes 3 made of expanded metal with, for example, 2 to 5 bits, are formed along the inside of the plate-like body 2 about 2 cm inside each surface on both the front and back sides.
Porous reinforcing plates 4, 4 having the following structures are arranged opposite each other, and the inner region partitioned by these porous reinforcing plates 44 is filled with a foamed lightweight aggregate 5 such as a glass balloon. In this way, the plate-shaped body 2 is entirely constituted by the foamed lightweight aggregate 5 filled inside, and its front and back surfaces are densely formed only by the cementitious composition 1, thereby improving surface hardness, durability, Constructed with excellent water absorption.

Furthermore, the plate-like body is formed by a porous reinforcing plate 474.

The cementitious composition 1 existing inside and outside each reinforcing plate 4 is effectively prevented from cracking on both the front and back surfaces of the reinforcing plate 3. Since the plate-shaped body 2 is integrally constructed through the .

Next, a method for manufacturing the exterior wall panel will be described, and there are two manufacturing methods according to the first invention and the second invention of the present application.

FIG. 2 shows an example of the implementation of the manufacturing method according to the second invention of the present application. In the figure, 6 indicates a formwork provided with a forming space 7 for the plate-shaped body 2. First, foaming is performed in the formwork 6. A filling space 8 for lightweight aggregate 5 exists, and the porous reinforcing plates 4, 4 made of expanded metal are arranged facing each other such that the lower ends of the inclined holes 3 are directed toward the filling space 8. Then, the fluid cementitious composition 1 is poured into the filling space 8 together with the foamed lightweight aggregate 5. At this time, since the lower end of each inclined hole 3 of the porous reinforcing plate 474 is oriented toward the filling space 8, the platform inclined hole 3 is directed outward, and only the fluid cementitious composition 1 is directed from the filling space 8 side. The foamed lightweight aggregate 5 passes through the platform inclined hole 3 and spreads over the entire area inside the formwork 6, and remains in the filling space 8 together with a small amount of fluid cementitious composition 1. Thereafter, the fluid cementitious composition 1 is solidified to obtain an exterior wall panel.

FIG. 3 shows an example of the implementation of the manufacturing method according to the third invention of the present application. In the manufacturing method of the second invention, both the flowable cementitious composition 1 and the foamed lightweight aggregate 6 are The material 5 was poured into the filling space 8, whereas the foamed light aggregate 5 was filled in the filling space 8 in advance, and then the fluid cementitious composition 1 was poured into the entire formwork 1. This is inserted into the inclined hole 3 of the porous reinforcing plate 474. . . . , and directly from above the foamed lightweight aggregate 5 into the gaps between the foamed lightweight aggregates 5 to solidify the flowable cementitious composition 1 after the foamed lightweight aggregate 5. Obtain exterior wall panels. According to this method, it is possible to easily manufacture an exterior wall panel in which the foamed lightweight aggregate 5 has a high volume.

(Effects of the Invention) As described above, according to the first invention of the present application, porous reinforcing plates are disposed facing each other along both the front and back surfaces inside a plate-like body formed of a cementitious composition, and Since the inner area separated by the reinforcing plate is filled with foamed lightweight aggregate, it is lightweight and has excellent surface hardness, durability, water absorption, etc., and does not cause cracking or peeling on the front and back surfaces, and can be formed into large sizes. It has the effect of producing exterior wall panels that can be used.

Further, according to the second and third inventions of the present application, the porous reinforcing plate, which is a component of the exterior wall panel of the first invention of the present application, is configured to have a large number of inclined holes that are inclined in the vertical direction,
By utilizing the inclined holes of such a porous reinforcing plate,
It has the effect of easily producing an exterior wall panel in which only the inside is filled with foamed lightweight aggregate and both the front and back surfaces are densely constructed with cementitious composition.
