Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mold for forming a tile base, in which various wall surfaces to which a tile is to be attached are subjected to a base treatment on irregularities.

[0002]

2. Description of the Related Art In order to prevent peeling and falling off of tiles,
It is known that a wall surface to be stuck on a tile is formed into irregularities. Explaining the conventional base treatment method,
After cutting an air cushion sheet (similar to a cushioning material for packing) in which a hemispherical air-containing convex group is formed on one side of the sheet in the same shape as a wooden formwork and affixing it to the formwork surface, the formwork is removed. Assemble and cast concrete. The spherical portion of the air cushion sheet is crushed by the concrete pressure, and a number of depressions are formed on the concrete surface. Remove the mold only leaving the air cushion sheet. When the strength of the concrete is developed, the air cushion sheet is peeled off, and a number of concave groups are formed on the surface of the wall body to which the tile is to be attached.

[0003]

The above-mentioned conventional undercoating technique has the following problems. <A> Since the air cushion sheet cannot be diverted, it must be replaced each time it is formed, which is uneconomical. <B> Although the work of replacing the air cushion sheet and the work of peeling off the air cushion sheet from each mold when removing the mold are performed manually, such work requires a lot of trouble and time. <C> After several days have passed since the mold was removed from the mold, the air cushion sheet had to be peeled off again, and the mold removal had to be performed twice, leaving room for improvement in process management. There is. <D> Since the convex portion of the air cushion sheet is formed of a soft sheet, the air cushion sheet is easily deformed or broken by the concrete driving pressure. For this reason, there are variations in the depressions formed on the surface of the wall frame.

[0004] The present invention has been made in view of the above points, the purpose of the present invention is to reduce the time required for demolding,
Moreover, it is an object of the present invention to provide a tile base forming form having excellent diversion properties.

[0005]

[0006]

Embodiment 1 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

<A> Overall Structure of Tile Undermolding Formwork FIG. 1 is an overall perspective view of a tile underformation mold 1. The mold 1 includes a mold main body 2 and a soft projection 4 integrally attached to a molding plate 3 of the mold main body 2. Hereinafter, each part will be described in detail.

<B> Form Body The form body 2 has a flange 5 and a reinforcing member 6 integrally formed on the back surface of a rectangular forming plate 3 and is formed of a hard resin or the like.
The conditions required for the mold body 2 need only be such that the molding surface has sufficient strength so as not to be deformed by the concrete pressure, and there is no restriction on its contour or the shape of the molding plate 3.

<C> Soft protrusions The soft protrusions 4 fixed to the front surface of the molded plate 3 at predetermined intervals are made of a soft resin (including rubber) having an appropriate elasticity and deformability, and are formed in a cylindrical or rod-like body. It is an elastic body formed in.
The interval at which the soft protrusions 4 are formed is a design factor that is appropriately selected in consideration of the size of the tile and the like. The soft projection 4 has a cross-sectional shape of, for example, a circle, an ellipse, a trapezoid, or the like, so that a dovetail-shaped depression can be formed on the surface of the wall body to be tiled.

The reason why the soft projection 4 is given an appropriate elasticity is as follows.
The reason for avoiding excessive deformation or crushing of the soft projections 4 due to the concrete placing pressure is given, and the reason for imparting appropriate deformability is to make it easy to remove the mold. The elasticity and deformability of the soft projection 4 can be adjusted by changing the wall thickness in addition to selecting the material of the resin.

The mold 1 composed of the mold body 2 and the soft projections 4 is manufactured at a time by a known resin extrusion molding. The mold 1 is obtained by extruding the resin and cutting the molded product at a predetermined length. In the mold 1 thus obtained, the soft projections 4 are firmly fixed to the mold body 2 by the self-adhesive force of the molten resin, so that no special bonding operation is required.

[0012]

Next, a method of attaching tiles using the above-described formwork 1 will be described.

<A> Assembling of the formwork As shown in FIG. 2, the formwork 1 is assembled using a known formwork positioning tool (PC 7, foam tie 8, steel pipe 9).
A metal fitting 10 having a U-shaped cross section is fitted between adjacent flanges 5 and 5 of each of the metal molds 1 and 1, and the metal molds 1 and 1 are connected by the spring force of the metal fitting 10.

<B> Concrete Casting After the assembly of the formwork 1 is completed, concrete is cast to construct the wall frame 11. Immediately after the concrete is cast, the soft projections 4 of the formwork 1 are subjected to the concrete casting pressure.
Maintains almost the original cross-sectional shape, slightly collapsed by its own elasticity.

<C> Demolding After a predetermined curing period has elapsed, the mold 1 is demolded. When the mold is removed, as shown in an enlarged view in FIG. 3, the soft projection 4 is deformed and peeled off from the wall frame 11 together with the mold body 2 while deforming the mold 1 by applying a mold removing force. A dovetail-shaped depression 12 is formed on the surface of the wall body 11 by the trace of the soft projection 4. If the dovetail-shaped recess 12 is molded from a hard material projection, the entrance portion of the dovetail-shaped recess 12 will be damaged when the mold is removed. On the other hand, the mold 1 of the present invention can protect the entrance portion of the dovetail-shaped dent 12 from being damaged when the soft projection 4 for molding the dovetail-shaped dent 12 is deformed. FIG. 4 shows the wall skeleton 11 that has been completely removed. The removed mold 1 is reused.

<D> Pasting of tiles As shown in FIG. 5, after forming a mortar layer 13 on the surface of a wall frame 11 having a large number of dovetail-shaped depressions 12 formed on the surface,
The work is completed by attaching the tile 14. Mortar layer 1
The dovetail 3 enters the dovetail-shaped recess 12 of the wall frame 11 and the dovetail-shaped recess 15 on the back surface of the tile 14, and firmly adheres the tile 14 to the wall frame 11.

[0017]

Second Embodiment The first embodiment has been described in connection with the case where the soft projections 4 are formed continuously. The soft projection 4 may be formed intermittently (intermittently).

[0018]

As described above, the present invention has the following effects.

<A> Since the soft protrusions are integrally attached to the mold body, the mold can be diverted, and each time molding is performed, compared to the conventional technique using an air cushion sheet,
It is economical because there is no need to replace the air cushion sheet.

<B> Conventionally, after removing the mold, it was necessary to remove the air cushion sheet again. However, in the present invention, since the soft projections can be removed together with the mold body, only one removal operation is required. In addition, the process management is simplified.

<C> Due to the elasticity of the soft projections, the soft projections can be effectively prevented from being excessively deformed or crushed by the concrete placing pressure, and a well-shaped dovetail-shaped depression can be formed on the surface of the wall frame. .

<D> Since the soft projection is deformable,
The peeling force required for the mold is smaller than when the projections are not deformed. Further, since the soft projection is deformed, the mold can be easily removed without damaging the dovetail-shaped depression.

<E> When the mold body and the soft protrusion are integrally molded by extruding a resin having a difference in hardness, the soft protrusion and the mold body can be firmly fixed at the time of molding without performing a special bonding operation. it can. Furthermore, since the formwork for forming the tile base can be manufactured only by cutting the extruded product to a predetermined length, the productivity is excellent.

<F> When a soft molded plate obtained by integrally molding a soft projection and a mold plate with a soft resin is attached to an existing steel or wooden mold body, only effective use of the existing mold can be achieved. Therefore, the manufacturing cost of the mold can be reduced.
