Now, what is the surface decoration method for fractured concrete blocks using the Sandquinona material of the present invention? explain.

The decorative material referred to here is a general term for surface materials mixed with colored concrete and mortar, as well as decorative stones.

First, fixed hopper 2 for backing is supplied with VC ordinary concrete, and then fixed hopper 3 for sandwich is supplied.
4 are respectively supplied with different material A for concrete, and the ordinary concrete is supplied to the ordinary concrete storage chamber 9 in the movable hopper 24 via the baffle plate 6 equipped with the charge hopper SVC.

On the other hand, the opening/closing shutter (not shown) of the fixed hopper 3 on the bottom of fixed phone ζ-3 and ζ-4 for sandwiches (hereinafter referred to as soup/do) is opened, and as shown in FIG. When about 70% of the sanding material A, which is the basis for breaking, has been fed into the decorative material storage chamber 8, a level switch (not shown) detects this and the partition member 10 is automatically inserted into the decorative material storage chamber 8Vc. Then, the shutter of the fixed hopper 4 for sand is opened, and the colored mortar 15 is fed onto the upper surface of the partition member 10 as shown in the sixth south.

When various materials are supplied to each compartment of the moving hopper 24 in this way, the moving hopper 24 is moved on the rail 25 by the roller 26 due to the differential movement of the cylinder 27, as shown in FIG. It moves to the stop position of the formwork 21.

At this time, the product receiving pallet 30, which has been placed in the formwork 21 in advance, is supported by the demolding rod 32 and raised to the surface of the formwork and is waiting there. When the partition member 10 is pulled out from the movable hopper 24 at the upper surface of the mold to fill the mold, a pseudo pattern with an appropriate mixed width is formed inside the movable hopper.

Then, while starting the camera 23, differentially move the slider 34 and gradually lower the stacker table 33 via the chain 37, and the product receiving pallet 30 supported by the demolding rod will also move at the same time. As shown in FIG. 3, various materials in the moving bar are filled into the space formed inside the formwork.

At this time, in the decorative material storage chamber 8 of the mobile hopper, the pseudo pattern of the colored mortar 15 formed by the partition member with an appropriate mixed width is controlled by the vibration motor 28 and form vibrator 23 as the pallet descends. It is filled into the formwork while maintaining an almost pseudo-pattern. In this case, the product receiving pallet in the formwork may not be raised to the top of the formwork, but may be stopped in the middle of the formwork or on the stopper 31 at the bottom of the formwork, and the material may be fed from the opening of the formwork. , may be determined as appropriate depending on the height of the product, the surface area ratio of the base Nandwich material, etc.

As a result, a layer of colored mortar is formed on top of the sanding material. When the intermediate fracture layer 20 is ruptured after curing and hardening, the surface of the fracture surface B has a uneven fracture surface with a mottled pattern due to colored mortar in the sanding material. Fractured surface B is created by partially mixing the basic sanding material VC with colorful mortar of different materials and colors in the decorative material storage chamber 8.
It forms a surface pattern with a rich variety of different colors.

The embodiments shown in FIGS. 7 and 8 are based on f/de material Ar.
It is divided by a partition member 10 and colored mortar 15 is placed on its upper surface.
In this example, when the partitioning member 10 is retreated on the upper surface of the formwork 21, the color mortar 15 is placed in the space formed, with the top and bottom being the main tone. It is surrounded by the sanding material A and filled into the mold while maintaining a predetermined mixed width. In addition, the partition member 10 is inserted into the hollow nozzle 18.
Decorative materials to be mixed with the basic sand material are packed in advance into the container, and when the hollow bib 118 retreats from the decorative material storage chamber 8, the decorative material is stored in the space using the push rod 19. How to feed material while displacing it in chamber 8? This is an example in which this is added.

This method does not require the installation of fixed hoppers or charge hoppers for each type, and it is possible to reliably form decorative materials with different colors at predetermined positions on the basic sanding material. Different materials? in parallel or
Alternatively, seven pipes can be provided for each color scheme to form broken surfaces with many different color patterns.

The implementation row in FIG. 11 vertically divides the decorative material storage chamber 8 into a dividing plate 13'a? After the sanding materials of different colors are received through the adjustable communication holes 14 provided in the board, the sanding materials are placed in the decorative material storage chamber 8 and placed in the formwork. You can form a colorful surface pattern by filling the inside of the partition plate 1 as shown in Figure 12.
3 may be made rotatable to form a surface pattern by adjusting the filling amount of the base material for dots and other decorative materials.

Although Embodiments 3 and 4 have been described above, the surface decoration method using the Su/Dwitte material of the present invention does not necessarily require pulling out or retracting the partition member on the upper surface of the formwork, but it is possible to form a pseudo pattern in the moving hopper. It may also be determined in advance through experiments, etc., depending on the material used, surface pattern, molding conditions, etc.

In addition, the partition member may be made of a flexible material and inserted into a curved shape to create a curved section, or the partition member shape may be made of a stainless steel plate or a sloped structure, or other partition members may be inserted!
'? It goes without saying that it can be appropriately selected and varied in many ways depending on the shape of the flock C, such as by changing the surface fracture pattern.

<Effects of the Invention> Flaw 1 According to the present invention, it is possible to easily apply colorful decorative materials with a variety of colors and different materials on the surface of conventional broken conocret products for dry mouth, which have been single-colored and single-colored. The present invention provides a manufacturing method and equipment that can be used to form decorative patterns on the surface of concrete products, which have recently been rapidly increasing in demand, and are highly effective in mass production.
