[Industrial applications]

 TECHNICAL FIELD The present invention relates to a formwork device for molding a concrete breaking block used for a structure such as an outer wall or a fence.

[0002]

[Prior art]

 The concrete breaking block is usually a concrete block having a fracture surface 3-2 on one surface of an ordinary concrete block 2 as shown in FIG. As shown in FIG. 4, such a fractured block is usually formed by forming one block having a size of two pieces with the fractured surface 3-2 of the concrete fractured block in FIG. The two broken blocks are manufactured by breaking at the position of. For that purpose, a row of hanging metal fittings for forming the unevenness 3-3 on the center line in the formwork is suspended by a suspending tool, concrete material is supplied into the formwork, and a concrete block is formed by vibration and pressure, After curing, the concrete block is broken on the center line 3 of this composite. However, when forming two blocks, the lifting tool is located on the center line 3-3, so the material supply and pressurization at this part are not performed sufficiently, so the problem is that the packing density of concrete is low. Are known.

In order to avoid this, conventionally, there is a method of suspending both hanging metal fittings for forming the unevenness 3-3 from both sides and pressurizing the center line to be broken with a pressing die that enters into the hanging equipment on both sides. Alternatively, it is known to hang the hanging metal fittings with a hanging tool to apply pressure in the same way as above, but with the method of hanging from both sides, the pressing surface of the pressing die is small and sufficient pressure can be applied. There is a problem that it will not be opened, and the method of hanging by one side with a lifting tool will cause uneven pressure, which may cause damage to the lifting tool and deformation of the hanging metal fitting, resulting in many defective products. .

[0004]

[Problems to be solved by the device]

 The present invention is intended to provide a formwork device that can evenly feed concrete into the formwork, and that the die can sufficiently press the fracture surface, resulting in fewer defective products. To do.

[0005]

[Means for Solving the Problems]

 The structure of the present invention for solving the above-mentioned problems is a form device for a broken block as described in the scope of utility model registration claims. The above configuration will be specifically described with reference to FIGS. 1 and 5. A row of hanging fittings 4 arranged on the center line 3 in the mold 1 and hanging tools 5, 5-for hanging the row of the hanging fittings. 2 are provided, and on both sides of the row of the above-mentioned hanging metal fittings, there are rows of hanging cores 8 parallel to it and core hanging metal fittings 7 and 7-2 for hanging the row of the hanging cores. Further, a central support member 6 for fixing the hanging members 5, 5-2 to the core hanging metal fittings 7, 7-2 so that the row of the hanging metal fittings 4 is located at the center of the row of the hanging cores 8. This is a broken block formwork device configured to press-form from the left and right toward the center line 3 after supplying concrete to it. The formwork apparatus of the present invention is inevitably fixed by the central support member 6 so that the relative positions of the core hanging metal fittings 7, 7-1 and the hanging tools 5, 5-2 do not change during the block forming operation. The relative positions of the hanging bracket 4 and the hanging core 8 are maintained constant. Therefore, the dimensional accuracy of the molded block is improved, and the state of the fracture surface 3 of the block is of constant quality.

【Example】

 The formwork apparatus of the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view of the entire formwork apparatus of the present invention, FIG. 2 is a sectional view taken along the line AA of FIG. 1, and FIG. FIG. 3 is a perspective view showing the relationship between the hanging tool and the suspension, and the central supporting member. In the form 1 shown in FIG. 1, the hanging core 8 is hung by the core hanging metal fitting 7, and the hanging metal fitting 4 for forming the uneven surface of the product is suspended so as to be aligned on the center line 3. Half of the rows of the hanging metal fittings 4 are fixed to the upper surface of the left side of the hanging metal fittings by the hanging equipment 5, and the other half are fixed to the upper surface of the right side of the hanging metal fittings 5-2. -2 and a central support member 6 which is fixedly supported.

A method of manufacturing a fractured block using this formwork will be specifically described. A concrete material is put into a void portion of the formwork, and an eccentric weight 10 is rotated by a rotating shaft 9. A vibrating body and a pressure plate. 12 forms a concrete block. That is, the material feeder moves forward and backward from above the formwork of FIG. 1 along with the hanger 5,5-2 and the core hanging metal fitting 7,7-2 to feed the material into the formwork. The suspensions 5 and 5-2 are reinforced and fixed to the core suspension metal fittings 7 and 7-2, and the concrete material feeding surface is pressure-molded by the pressure plate 12 while avoiding the positions of these metal fittings. As shown in FIG. 4, a concrete block having an uneven surface 3-3 can be molded. After this is cured and dried on the receiving plate 11, it is fractured at the position of the center line 3 to obtain two fractured concrete blocks having a fracture surface 3-2 as shown in FIG.

[0008]

[Effect of device]

 As described above, according to the formwork of the present invention, the suspending metal fitting for forming the fracture surface can be suspended in the formwork in a stable state, and the feeding and pressurization on the center line are sufficient. , It is possible to produce aesthetically homogeneous products without producing defective products.
