Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a hollow perforated concrete panel in which decorative tiles are integrated into the concrete panel.

A conventional method for producing precast concrete panels is to lay tiles in a box and pour wet concrete with a slump of around 4 into the box.

To manufacture hollow perforated concrete panels using the zero slump concrete continuous movement forming method described later,
I would like to be able to manufacture it by arranging tiles like this and pouring ready-mixed concrete.

This is because, as the molding machine moves, the joints between the tiles that are laid out become clogged.

To get rid of this, you have to use a net.

Also, regarding the side joints of tiles, concrete does not enter the finished surface side during pouring.

As a result of various studies, the inventor of the present invention solved the problem of tile joint misalignment by using a special tile that serves as a tile butting (engaging) joint for the joint on the concrete pouring side.

The method for manufacturing the tile-integrated hollow perforated concrete panel of the present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a sectional view taken along line A--A in FIG. 2, showing a state in which the decorative tiles used in the method of the present invention are laid side by side with their surfaces facing down.

FIG. 2 is a cutaway side view of the main parts of the concrete panel continuous forming machine.

FIG. 3 is a longitudinal sectional view of the concrete panel after forming.

FIG. 4 is a sectional end view taken along line BB in FIG. 2.

In Fig. 2, the concrete placing table 3 is long in the front and back,
Its length is approximately 200m.

Therefore, the concrete panel made with this device is cut into a predetermined size with a cutter to become a product.

In the present invention, the tiles 8 are first laid out on the concrete placement table 3 with the surface 15 facing downward before concrete placement.

This tile 8 is unique in its structure, and has a structure in which adjacent tiles can be attached to each other.

That is, as seen in FIG. 1, one end of the tile has a downward hook shape, and the other end has an upward hook shape.

By providing the hook-shaped hook portions 16 and 17, a large number of tiles 8 can be engaged continuously.

Therefore, the tiles are laid in the longitudinal direction of the concrete placement table 3 as shown by the arrows in FIG.

When the tiles are laid out, the PC steel wires 2 are reinforced.

Next, as shown in FIG. 2, the continuous forming machine 1 is moved forward to pour ready-mixed concrete 13 onto the tiles 8.

In order to improve the bonding with concrete on the back side of the tile 8, the mortar adhesion groove 14 on the back side of the tile is not a conventional parallel groove, but the width of the groove inside the tile is made wider than the adhesive width to improve the bite of mortar.

Concrete pouring will be carried out in two stages.

First, fresh concrete is placed in the hopper 19 up to the lower part of the arrow 18 for forming the core.

Next, the fresh concrete in the hopper 5 is poured while opening the gate 6, but the gate 6 and the tamper 4 are arranged in a seesaw shape, and when the gate 6 goes up, the tamper 4 goes down. It is compacted onto concrete.

Arrow 18 is for installing core 10 in the concrete panel.

The arrows 18 are suspended from the top by support stays, and the grooves formed on the concrete by the support stays are filled with finishing mortar supplied by the finishing mortar hopper 11 at the rear.

The rear thickness finishing plate T adjusts the thickness and corrects the grooves caused by the rond to smooth the surface.

As the continuous molding machine advances, the concrete panel is removed from the side plate 12.

In this way, as the continuous forming machine 1 moves forward, a concrete panel 9 is formed at the rear.

According to the method of the present invention as described in detail above, even if concrete is poured as the continuous molding machine progresses, the individual tiles are connected by the hook portions, so tiles do not shift and the tile joints are maintained at a constant level. This made it possible to manufacture products that matched the design dimensions.

Furthermore, by mass-producing tile-integrated hollow perforated concrete panels using the method described above, it has become possible to provide products at low prices and with excellent designs.

Claims (1)

[Claims] 1. To form multiple cores in a panel, while moving forward the forming machine with arrows placed at the bottom of the hopper, the ready-mixed concrete in the hopper is poured to the bottom of the arrows, and then the gate moves up and down to move the concrete to the next hopper. When continuously forming a long hollow perforated concrete panel using a forming machine that has a structure in which the fresh concrete inside is poured and compacted with a tamper, and then the surface is finished with finishing mortar, the concrete is poured into a concrete panel. A method for manufacturing a tile-integrated hollow perforated concrete panel, which comprises laying tiles on a table having hook portions that allow adjacent tiles to engage with each other, and then pouring and hardening fresh concrete.
