Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a mold and jig for manufacturing concrete blocks with decorative materials that can improve quality and productivity.

<Conventional technology> Generally, when constructing external walls, gates, fences, etc. of buildings using concrete blocks, in order to enhance the design effect, a finishing method is used in which decorative materials such as tiles or natural stone are pasted on the surface of the concrete blocks. It is well known that construction is required.

This finishing method involves on-site work in which decorative materials are pasted one by one in a predetermined pattern on the surface of concrete blocks via mortar, so mortar is applied to the surface of the concrete block prior to pasting the decorative materials. In addition to the need to transport and store materials, it was also necessary to secure a tile craftsman, making it difficult to construct, leading to delays in the construction period and increased construction costs.

Therefore, recently, a concrete block with a decorative material has been considered in which a decorative material is applied to the surface of the concrete block in advance by the manufacturer of the concrete block, and the concrete blocks are simply stacked in layers at the site.

In manufacturing this concrete block with decorative material, as shown in FIG. It is stored in a recess 3 formed on the upper surface of the bottom wall of 1. Next, after pouring the mortar 4 with improved adhesiveness into the mold 1, the surface of the concrete block 5 (Jl is referred to as the lower surface) is immediately pressed onto the mortar 4 manually or with a press. It is effective from various points of view to dry and harden the mortar 4 in this pressed state and then to unmold it to produce a concrete block with a decorative material.

<Problems to be Solved by the Invention> However, in the above-mentioned manufacturing method, the positioning of the concrete block 5 with respect to the mold 1 was performed by the intuition of the worker, so the positioning work was time-consuming and the decorative material was not attached to the concrete block. On the other hand, there was a problem in that the decorative material was tilted to the surface of the concrete block, resulting in poor positioning accuracy of the decorative material with respect to the decorative surface of the concrete block, resulting in a decrease in quality and productivity.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a mold and jig for manufacturing concrete blocks with decorative materials that can improve quality and productivity.

<Means for Solving the Problems> The present invention that achieves the above object comprises a rectangular bottom wall, a recess formed on the upper surface of the bottom wall into which a part of the decorative material is fitted, and the bottom wall. A weir plate that stands up from the periphery of the base wall for pouring mortar onto the upper surface of the bottom wall; - A weir plate that protrudes integrally from two adjacent plate parts of the shear plate and that is pressed against two adjacent end faces of the concrete block; a projection for positioning the concrete block with respect to the weir plate, a rectangular bottom wall, a recess formed on the upper surface of the bottom wall into which a part of the decorative material is fitted, and the bottom A jig used for a mold for manufacturing a concrete block with a decorative material, which has a weir plate that stands up from the m edge of the wall and is used to pour mortar onto the top surface of the bottom wall, the jig being used for a mold for manufacturing a concrete block with a decorative material, which has two adjacent sheath plate plates. a frame plate against which the outer surfaces of the two plate parts are pressed, and a flange formed integrally with the frame plate and against which two adjacent end surfaces of the concrete block are pressed, and for positioning the concrete block with respect to the above-mentioned girder plate. It is characterized by having a shaped plate part.

Function> According to the above-mentioned structure, the decorative material is stored in the recess, and then mortar is poured into the weir wall, and then the decorative surface of the concrete block is pressed onto the mortar to spread the mortar. After drying and curing, a concrete block with decorative material is completed. In addition, by pressing the two adjacent end faces of the concrete block against the protrusion or flange-like plate portion, the concrete block can be positioned quickly and accurately with respect to the mold.

Example of implementation The present invention will be described in detail below based on the accompanying drawings.

As shown in FIG. 1, the mold 10 has a weir plate 12 of a predetermined height erected from the periphery of a rectangular bottom wall 11.
Mortar A (see Fig. 3) is poured into 2.

On the upper surface of the bottom wall 11 surrounded by the weir plate 12, as shown in FIG.
3 are formed at equal intervals in the longitudinal direction of the mold 10,
The lower half of the tile B (see FIG. 3) as a decorative material can be fitted into these shallow recesses 13.

Further, the upper surface of the bottom wall 11 surrounded by the weir plate 12 is formed to have approximately the same area as the decorative surface of the concrete block C (see FIG. 3).

Then, the left side plate part and the rear plate part of the weir plate 12 are extended upward by a predetermined height from the other two plate parts, and these re-extended plate parts 12g and 12b serve as projections for positioning concrete blocks. It's supposed to work. That is, during manufacturing, the concrete block C is positioned relative to the mold 10 by pressing two adjacent end surfaces of the concrete block C against the re-extension plate parts 12m and 12b.

Note that it is not necessary to provide the re-extension plate portions X2m and 12b over the entire length of each plate portion. Furthermore, the mold 10 configured as described above is made of a foamed synthetic resin such as polyethylene foam molded using a foaming agent that generates gas, and it is easy to remove the mold after the mortar has hardened. It is desirable to take care to ensure that there is no risk of chipping of the product.

Therefore, if the same method as shown in FIG. 5 is adopted using the mold 10 described above, a tiled concrete block as shown in FIG. 3 will be manufactured. At this time, the above-mentioned re-extension'! I
The concrete block C can be positioned quickly and accurately with respect to the mold 10 by the parts 12m and 12b. Further, after this positioning, the mold 1 or the concrete block 5 side may be vibrated as appropriate using a vibrator (not shown).

In the above embodiments, the decorative material is not limited to tiles, but may also be natural stone or wood, and the shape and quantity of the decorative material are also determined by the shallow recesses 13 of the mold 10.
If you match it, you can choose it arbitrarily.

In addition, if the joint end surfaces of concrete blocks with decorative materials manufactured in this way are finished with high precision using a diamond cutter, even an amateur can easily perform jointless reed work using only synthetic resin adhesive without using mortar. It becomes possible to do so. At this time, if tiles are used as a decorative material, the dimensions of the concrete block are determined, leaving out the joints. In addition, when using a single board made of natural wood, the end face of the natural stone material is also cut off when the end face of the concrete block mentioned above is cut so that the entire decorative surface is made of natural stone material.

The embodiment shown in FIG. flIJ4 is an example in which the protrusion for positioning the concrete block in the above-mentioned mold is used as a positioning jig and is formed separately from the "C-shape."

That is, the left side plate part 15 and the rear plate part 16 are respectively erected from the left side edge and the curvature of the metal base plate 14, and the upper ends of these drawing board parts 15, 16 are moved inward in the form of a flange. By bending these flange-like plate portions 15a, 16a, they function as projections for positioning concrete blocks. In the figure, reference numeral 17 denotes an auxiliary plate part for holding the mold when the mold 10 (in this case, it does not have the extension plate parts 12a, 12b) is set on the base plate 14, and does not need to be provided. Moreover, if the left side plate part 15 and the rear plate part 16 can be properly fixed to the mold 10, the base plate 14 may not be particularly provided. In this case, it is preferable that the left side plate part 15 and the rear plate part 16 are integrally formed with a five-shaped frame plate.

<Effects of the Invention> As explained above, according to the present invention, the positioning protrusion or flange-like plate allows the concrete block to be positioned quickly and accurately with respect to the mold, and therefore the concrete block with decorative material can be positioned quickly and accurately. Quality and productivity can be improved.
