Description

Description: FIELD OF THE INVENTION The present invention relates to a method and apparatus for the composite integration of concrete blocks and decorative materials such as tiles or natural stone.

[Prior Art] Conventionally, most of the techniques for adhering a decorative material such as tiles or natural stones to the surface of a concrete block with an adhesive mortar are by hand. In the mechanized one, it is known to apply a decorative material while moving the block on the conveyor. Also known is a method in which a mortar is put into a frame through an elastic body such as rubber and then a concrete material is put into the frame to make a composite by vibrating and pressurizing.

[Problems to be Solved by the Invention] Mechanization is a major precondition for improving inefficiency by hand, but it is difficult to manufacture products with good dimensional accuracy and aesthetics using conventional methods, or Are limited to composites of flat plates and decorative materials.

The present invention enables a composite of a concrete block and a decorative material to be mechanically mass-produced with high dimensional accuracy and without impairing aesthetics.

[Means for Solving the Problems] According to the present invention, a concrete block placed on a push-up base is pushed up into a through hole of a fixed frame from below, and adhesive mortar is supplied to an upper side of the fixed frame and an upper surface of the block. A space is provided and adhesive mortar is supplied to the space, then the push-up base is slightly lowered, a decorative material smaller than the through hole of the fixing frame is placed on the adhesive mortar, and pressure contact dynamic pressure bonding The adhesive mortar is caused to flow in the gap between the decorative material and the fixed frame so that the adhesive mortar holds the periphery of the decorative material and the decorative material and the concrete block are combined and integrated, and then the push-up base is lifted on the upper side of the fixed frame. , A method of manufacturing a composite concrete block in which a composite product is scooped from the side and demolded.

The present invention also provides a fixed frame having a through hole for performing the above method, an extrusion table that penetrates into the through hole of the fixed frame, and a mortar supply mechanism, a cosmetic material supply mechanism, and a pressurization mechanism above the fixed frame. This is an apparatus for manufacturing a composite concrete block in which a vibration mechanism is provided and a product take-out mechanism is further provided on the side of the fixed frame.

If the fixed frame is divided into two or four parts and has a structure that opens and closes in the horizontal direction, the positioning of the blocks can be made more accurate.

[Operation] The mortar and the decorative material are automatically supplied to the upper surface of the concrete block to bond the concrete block and the decorative material with the mortar, and the mortar slides up the gap between the periphery of the decorative material and the fixed frame. Then, the decorative material is fixed and the peripheral dimensional accuracy is improved. Furthermore, the product is removed from the fixed frame in a die-cut manner so as not to stain the surface of the decorative material.

[Embodiment] FIG. 1 is a plan view of an embodiment of the present invention, and FIG. 2 is a side view for explaining a main part thereof. Reference numeral 1 is a formwork fixed to the machine body 2, on which a supply box 5 and a mortar hopper 6 which reciprocate on rails 4 and 4 by the action of a cylinder 3 are provided.
A cylinder 6 is provided below the formwork 1. A push-up base 8 that moves up and down by a cylinder 7 is provided at the bottom of the formwork 1, and the push-up base 8 is fed from the lateral direction by a conveyor. Further, a rail 12 for supplying the cosmetic material 11 is provided on the formwork 1 from a direction different from the direction of the supply of the material box 5, and a cosmetic material gripping device that reciprocates on the rail 13 (not shown). ) Is provided. A vibration pressing plate 15 which is moved up and down by the action of the cylinder 14 is provided directly above the mold 1. 16 is a vibrating body. Reference numeral 17 is a scooping device that rotates up and down about a rotation shaft 18, and 19 is a conveyor for conveying the demolded product.

3 to 9 are explanatory views in the order of steps.

First, FIG. 3 shows that the concrete block 10 conveyed by the rail 9 is placed on the push-up base 8. Fourth
The figure shows the lifting platform 8 pushed up by the action of the cylinder 7,
The concrete block 10 has just been inserted into 1. At this time, the upper surface of the concrete block 10 is
Located below the top of the. Into the formwork 1 on the top of the concrete block 10
The mortar 20 is supplied from the supply box 5 moved by the action of 3.

Then, as shown in FIG. 6, the supply box 5 is pulled to the lower part of the mortar hopper 6, and the decorative material gripping device moving on the rail 13 holds the decorative material held in the mortar inside the mold 1.
Place on 20. FIG. 7 shows that the vibrating pressure plate 15 is lowered by the action of the cylinder 14 and the vibrating body 16 is vibrated while the decorative material is applied.
11 is pressed, and the decorative material 11 and the concrete block 10 are bonded together via the mortar 20. At this time, the mortar 20 slides up the periphery of the decorative material 11 and is fixed so as to hold the periphery of the decorative material 11.

Fig. 8 shows the product with the decorative material 11 adhered to the cylinder 7
By the action of, the push-up table 8 pushes the mold 1 upward. Then, as shown in FIG. 9, the scooping device 17 is moved forward to take out the product from the upper part of the mold, and after retreating, the product is transferred 90 ° by the rotary shaft 18 and transferred onto the conveyor 19 in FIG. And carry it out.

FIG. 10 shows another embodiment of the mold 1 in which the mold is divided into two 1, 1 ', which are opened and closed by the action of cylinders 21, 21'. The formwork may also be split to move in four directions.

[Advantages of the Invention] The present invention is as described above, and has an effect of mass-producing a composite concrete block including a concrete block and tiles or a natural stone material as a decorative material with good dimensional accuracy without soiling the surface of the decorative material. Further, since the decorative material is formed in a state of being held with the adhesive mortar, the connection with the concrete block becomes strong.
