2. Description of the Related Art Conventionally, a pallet mold which is generally used when manufacturing this kind of concrete product is a pallet mold which is made of metal and has a pattern formed by forming an uneven surface as shown in FIG. 12 and a pallet mold 12 made of a synthetic resin, which is made of a resin mold 11 in which a synthetic resin is poured and cured in a bottomed mold 10 made of metal as shown in FIG. .

[0003]

However, since the above-mentioned conventional metal pallet mold 12 is press-molded at the time of manufacturing, the irregular pattern on the surface becomes a geometrical design and an irregular pattern is molded. However, even in the pallet mold 12 made of synthetic resin, since the surface of the irregular irregular pattern is smooth, it is not possible to express a rich surface and the finished surface of the concrete product becomes artificial. was there.

The present invention has been made in view of the above problems, and the surface thereof can be molded into a desired shape and the surface can be molded into a rough surface, and even if a concrete product is manufactured for a long period of time, cracking or peeling occurs. An object of the present invention is to provide a method of manufacturing a pallet mold which has a long life and can be used without being damaged.

[0005]

The feature of the pallet type manufacturing method for solving the above problems of the present invention is that the aqueous gel 8 is applied to the upper surface 7a of the mother die 7 having a surface design of a desired shape. At the same time, a frame-shaped mold 1 is attached to the upper edge of the mother mold 7 to fill the inside thereof with resin concrete as the concrete material 5, and the surface layer portion of the resin concrete that comes into contact with the coating of the aqueous gel 8 The surface design of the mother die 7 is transferred to the pallet surface 6a by suppressing the hardening and integrally fixed to the mold 1, and the aggregate in the concrete material 5 is exposed to make the pallet surface 6a a rough surface. It is about molding.

[0006]

When the pallet mold for concrete product molding manufactured by the above pallet mold manufacturing method is used, first, a side frame is assembled to the pallet mold for concrete product molding, and fresh concrete is poured into the pallet mold. And then the raw concrete is hardened in the concrete product molding pallet mold and the side frame, whereby the desired shape of the surface of the concrete material 5 integrated in the concrete product molding pallet mold is transferred. Concrete products will be manufactured. At this time, even if the weight of the fresh concrete is applied to the concrete material 5, the concrete material 5 retains rigidity and is fixedly integrated with the formwork 1, so that the surface is damaged or the formwork 1 and the concrete material 5 are Since it can be used for a long time without peeling, it becomes extremely economical.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a metal mold frame formed in a square frame shape in plan view. The mold frame 1 has an upper end edge which is bent outward and obliquely upward. A bent piece 2 is provided around the lower end side of which a flange piece 3 is bent at a substantially right angle toward the inside.

Reference numeral 4 denotes a bar-shaped reinforcing bar as a reinforcing member, which is welded in a lattice shape to the lower side of the mold 1.

Reference numeral 5 denotes a concrete material which is integrally fixed in the mold 1 and has a desired shape so that the surface thereof serves as a pallet surface 6a. Inside the concrete material 5, the reinforcing material 4 is provided. ... is buried.

The concrete product molding pallet mold 6 manufactured by the pallet mold manufacturing method according to the present invention has the above-mentioned structure. Next, a concrete method for manufacturing the concrete product molding pallet mold 6 will be described in detail. explain.

First, as shown in FIG. 3A, a mother die 7 having a desired surface design is prepared, and at the same time, the mother die 7 is prepared.
The aqueous gel 8 is applied to the upper surface 7a of the above, and then the mold 1 is attached to the upper edge of the mother mold 7 with the bending piece 2 facing downward as shown in FIG.

Then, as shown in FIG. 3C, resin concrete containing a curable resin (polyester resin, epoxy resin, urethane resin, etc.) as the concrete material 5 as a binder is opened from the upper opening of the mold 1. When the inside of the pallet mold 6 for molding concrete products having a surface design as shown in FIGS. 1 and 2 is manufactured by removing the mold 1 after a predetermined time has passed, the pallet mold 6 is manufactured.

Further, in the pallet mold 6 for molding concrete products, the aqueous gel 8 applied to the upper surface 7a of the mother mold 7 (water-soluble polymer and acid added to water)
Since the hardening of the surface layer portion of the resin concrete as the concrete material 5 contacting the coating of (3) is suppressed, the aggregate in the concrete material 5 is exposed on the surface of the pallet surface 6a and the pallet surface 6a becomes a rough surface. It is formed.

Next, a case of producing a concrete product by using the concrete product molding pallet mold 6 will be described.

First, as shown in FIG. 4 (a), the concrete product molding pallet mold 6 is installed so that the bending piece 2 of the mold 1 is on the upper side, and then the outer periphery of the bending piece 2 is placed. Then, the side frame 9 is assembled and fixed.

Then, when the fresh concrete 13 is poured into the space portion constituted by the pallet surface 6a, the bent piece 2 and the side frame 9, as shown in FIG.
3 fills the space, and then the fresh concrete 13 is hardened in the pallet mold 6 for concrete product molding along the surface of the concrete material 5, that is, the shape of the pallet surface 6a.

Then, by removing the pallet mold 6 and the side frame 9 for molding the concrete product, as shown in FIG.
And a concrete product 1 in which the surface design as shown in (b) is formed in an irregular shape and the upper surface is formed into a rough surface.

The pallet mold 6 for concrete product molding and the concrete product 14 can be easily removed.

In the above embodiment, the mold 1 is formed in a square shape in plan view, but the shape of the mold 1 is not limited to this, and for example, FIGS. , And as shown in FIG. 7A, it may be formed in a frame shape such as a substantially rectangular shape, a triangular shape, or a rectangular shape with four corners cut off. In short, the plane shape does not matter as long as it is formed in a frame shape. Further, the design of the pallet surface 6a also depends on the design of the upper surface 7a of the mother die 7 as shown in FIGS. 6 (a) to 6 (c), and FIG.
As shown in (b), the design can be changed arbitrarily.

Further, although the entire surface of the pallet surface 6a is molded into a rough surface by using the aqueous gel 8, the present invention is not limited to this, and a part of the pallet surface 6a may be molded into a rough surface.

Further, as shown in FIGS. 8A and 8B, when the design of the pallet surface 6a formed by the concrete material 5 is deeply formed and the height of the mold 1 becomes high, the concrete material 5 is formed. Notch 1a
It is also possible to form the concrete product molding pallet mold 6 in which the height of the formwork 1 is partially different by forming the.

Further, in the above-mentioned embodiment, a grid-shaped reinforcing bar group is welded to the formwork 1 as the reinforcing material 4, and the concrete material 5 filled in the formwork 1 is fixedly integrated with the formwork 1 and the reinforcing material 4. However, in the method of manufacturing the present pallet type, disposing the reinforcing material is not an essential condition.

INDUSTRIAL APPLICABILITY As described above, the present invention forms a pallet mold for concrete product molding in which a frame-shaped metal mold and a concrete material having a desired surface design are formed in the mold. Because it is possible, it is possible to mold an irregular surface pattern that cannot be produced with the conventional metal pallet type,
Since the concrete material and the formwork are fixed and integrated to form a strong structure, cracking, peeling, damage,
A particularly remarkable effect that the pallet type has a long life without being deformed has been obtained.

Further, since the pallet surface formed by the concrete material is molded into a rough surface, the rough surface is transferred to the surface of the concrete product, and the rough surface and the irregular surface pattern are mixed with each other. It also has the effect of being able to form concrete products that are natural and rich in taste.

Further, when molding pallet molds for concrete product molding having different formwork heights, the extraneous portion of the concrete material is cut off to form the notch, so that the concrete material can be reduced and it is economical. In addition, the weight of the pallet mold itself for concrete product molding can be reduced, and further, the cutout portion can be used as a locking portion during transportation.
