Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a precast wall in which a decorative stone slab or the like is attached to a concrete wall and a method of manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, the walls of buildings such as buildings have
As shown in FIG. 3, a precast wall 3 is used in which a plurality of decorative plates 2 such as a slab and a tile are attached to the outer surface side of a concrete wall body 1. When manufacturing this kind of precast wall 3, first, on the bottom plate of the formwork,
A decorative plate 2 attached with a metal fitting (not shown) for joining to the wall main body 1 is spread, and then concrete is poured into a formwork, and a precast wall whose surface is covered by the decorative plate 2 No. 3 was molded.

[0003]

By the way, when the above-mentioned precast wall body 3 is manufactured, the precast wall body 3 is formed between the decorative plate bodies 2 on the surface side so that the poured concrete does not leak to the surface side. In addition to disposing the back-up material for filling, filling the back surface with joint sealing material, removing the back-up material for manufacturing after demolding, pushing in the backup material for permanent installation, and filling the sealing material from the front side There is a problem that the work must be performed, and the work requires a great deal of labor and labor.

[0004] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a precast wall body capable of performing a sealing operation very easily and facilitating a manufacturing operation, and a method of manufacturing the same. I have.

[0005]

In order to achieve the above object, a precast wall according to the present invention comprises a concrete wall body and a plurality of wall members arranged on the surface of the wall body. A precast wall composed of a decorative plate and a joint between the decorative plates, a flat plate portion covering the joint from the back side, and a projection provided on the flat plate and fitted into the joint. A joint member having a ridge is provided. A precast wall according to a second aspect is the precast wall according to the first aspect, characterized in that a hole is formed in a center portion of the ridge portion of the joint member. In the method for producing a precast wall according to claim 3, on a bottom plate constituting a mold,
A plurality of decorative plate members are arranged, and the joints between the decorative plate members are attached from the back surface side while fitting the protrusions of the joint member having the protrusions formed on the plate-like flat plate portion, and then Then, concrete is cast on the upper surface side of the decorative plate to manufacture a wall body made of the concrete and a precast wall provided with the decorative plate arranged on the surface of the wall body. It is characterized by:

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A precast wall according to an embodiment of the present invention and a method for manufacturing the same will be described below with reference to the drawings.
In FIG. 1, reference numeral 10 denotes a precast wall.
The joint member 1 made of an elastic material such as rubber is jointed on the back side of the decorative plate 2 constituting the precast wall 10.
5 are provided. The joint member 15 has a flat plate portion 16 covering the joint and a ridge portion 17 formed at the center of the flat plate portion 16, and the ridge portion 17 serves as a joint of the decorative plate 2. Inlaid. A hole 18 is formed at the center of the ridge 17 so that good elasticity can be obtained. Also, this joint member 15
A joint 19 made of butyl rubber, epoxy resin or the like is filled and sealed in a corner formed by the end of the flat plate portion 16 and the decorative plate 2. Reference numeral 21 in the drawing denotes a back surface material provided for improving the bonding strength of the decorative plate 2 to the wall body 1 and made of, for example, epoxy resin containing silica sand or the like.

Next, the case of manufacturing the precast wall body 10 will be described along the operation procedure. (1) As shown in FIG. 2, first, a stone receiving plate 13 is installed on the bed surface 11a of the bottom plate 11 of the formwork, and the end of the decorative plate 2 is placed on the stone receiving plate 13 and installed. I do. Here, the stone receiving plate 13 is provided with an elastic sheet 12 such as rubber on its upper surface, and the joints of the decorative plate bodies 2 are connected to the bed surface of the bottom plate 11 via the stone receiving plate 13. 11a. Further, a spacer 14 is provided on the stone receiving plate 13, and a gap between joints of the decorative plate 2 is secured by the spacer 14. (2) In this state, from the back side of the decorative plate 2,
The joint member 15 is attached to the joint of the decorative plate 2 while fitting the protrusions 17 into the joint, and the joint member 19 is filled at both ends of the flat plate portion 16 so that the joint member 15 and the back surface of the decorative plate 2 are connected. Securely seal. (3) After that, concrete is poured into the formwork, and when this concrete hardens and cures, it is removed from the mold and the precast wall 10 is taken out.

By performing the above operations (1) to (3), the precast wall 10 in which the joints between the decorative plates 2 are securely sealed by the joint members 15 is manufactured. As described above, according to the method for manufacturing the precast wall body, the joint member 15 is attached to the joint between the decorative plate bodies 2 spread on the bed surface 11a of the bottom plate 11 of the formwork while fitting the protrusions 17 therebetween. It is very easy to manufacture the precast wall 10 in which the front side is covered with the decorative plate 2 and the joints between the decorative plate 2 are surely sealed simply by casting concrete. Thus, the working time can be reduced and the working efficiency can be improved. That is, as compared with the conventional method, in which the backup material is inserted into the joint and the front and back surfaces are sealed,
The manufacturing operation can be shortened and the efficiency can be improved, and the manufacturing cost can be significantly reduced.

[0009]

As described above, according to the precast wall of the present invention and the method for producing the same, the following effects can be obtained. According to the precast wall of the first aspect, the joints between the decorative plate bodies can be reliably sealed by the joint members, so that the back-up material is fitted into the joints and the back surface and the back surface are sealed as in the related art. The manufacturing cost can be greatly reduced as compared with a precast wall body having a structure having the following structure. According to the precast wall of the second aspect, since the hole is formed at the center of the ridge, good elasticity of the ridge can be obtained, and thereby the joint of the ridge is provided. It is possible to facilitate the work of fitting into the device. According to the method for manufacturing a precast wall according to claim 3, the joint of the decorative plate laid on the bottom plate of the formwork is attached to the joint member while the ridge is being fitted, and the concrete is simply poured in. Very easily,
It is possible to manufacture a precast wall body in which the front side is covered with a decorative plate, and the joints between the decorative plates are securely sealed, thereby shortening the working time and improving the working efficiency. it can.
