Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a brick having a chamfered part on the front side and a hanging part for embedding and fixing on the back side, and a method for manufacturing the same. It is related to.

Traditionally, chamfered bricks have been seen in which the ridgeline portions of the brick body are chamfered in order to improve its commercial value; Therefore, the chamfered part on the surface side can give a sense of luxury, and when such chamfered bricks are used for laying sidewalks, there will be no catch on the ridgeline, preventing pedestrians from falling. Although it is possible to prevent accidents, the back side is usually fixed with cement, etc., so if there is a chamfer on the ridgeline, the fixation strength of the cement will be reduced, and it may cause peeling or positioning after construction. This has disadvantages such as the possibility of problems such as slippage.

In addition, when cutting the molded base material, chamfered bricks are usually made by forming a V-shaped groove on the peripheral surface with a V-shaped engraving blade in advance, and cutting at the center of the V-shaped groove. Although the chamfered part is formed so as to be molded,
When cutting piano wire, it is extremely difficult to cut it so that it perfectly matches the center of the V-shaped groove with a cutting tool, so if the cutting center of the piano wire and the center of the V-shaped groove are misaligned, cutting Any of the chamfered parts on the surface creates an extra protrusion, which requires an extra finishing process such as removing the protruding part by finishing separately, which has the disadvantage of making the manufacturing process extremely complicated. was.

In view of these drawbacks, the present invention has a surface formed by forming a chamfered part on the ridgeline part on the front side of the brick body, and providing a hooking part extending inward and cutting into a groove shape on the peripheral edge part on the back side. An embodiment of the present invention will be described below based on the drawings, with the aim of solving the above-mentioned drawbacks by providing a brick having a handle and a hook and a method for manufacturing the same. The material is extruded into a predetermined cross-sectional shape, and in front of the extrusion molding machine 2, a conveyor 4 is connected in series to transfer the extruded material 1 to the subsequent cutting device 3. During the transfer route of No. 4, a plurality of brick bodies 5.5a...
A cutting machine 6 is arranged to cut the.

Reference numeral 7 denotes an engraving device installed in the transfer path of the conveyor 4, and is used to mark each individual brick body 5.5a on the substrate 1.
Engraving blades 8.8a are formed in a wedge shape with a single taper at opposing positions on the entire circumferential surface where the substrate 1 is to be cut in accordance with...
are arranged in such a way that it is possible to press them against the substrate 1.

Further, the cutting device 3 connected to the conveyor 4 presses the base material 1 against cutting tools 9.9a, such as piano wire, which are adjusted according to the spacing between the brick bodies 5.5a. It is made up of a pushbutton 10.

Note that the mechanisms and arrangement of the cutting device 3 and creation device 7 are not limited to those shown in the drawings.
．． 8a... After pressing the base material 1 into each brick body 5.5
Any mechanism may be used as long as it is capable of performing cutting processing on a single unit of a.

Next, the method for manufacturing a brick having a chamfered part and a hanging part according to the present invention will be explained. First, the base material 1 extruded by the extrusion molding machine 2 is formed into a predetermined shape corresponding to a plurality of brick bodies 5.5a... After being cut to length, each engraving blade 8.8a of the engraving device 7 is conveyed sequentially by the conveyor 4, and the engraving blades 8.8a... of the engraving device 7, which were waiting on the conveyance path, are placed on the circumferential surface of the substrate 1 to be cut. Engraving blade that is pressed and applied 8.8
A cut surface 11 is formed on the circumferential surface of the substrate 1 due to the pressing of a...
A groove portion 14 consisting of a face 12 and an inclined surface 13 parallel to the groove 12 is provided around the periphery.

Subsequently, the substrate 1 with the groove 14 around it is transferred to the cutting device 3 side by the conveyor 4, and in this process, the button shear 10 is operated with respect to the cutting tools 9.9a arranged at the front facing position. By pressing the base material 1, it is cut into individual brick bodies 5.5a, . . . .

When performing the cutting process, the arrangement of the substrate 1 and the cutting tools 9,9a, etc. is set so that the cut surface 11 of the substrate 1 corresponds to the midway position of the slope 13 in the groove 14, and in this setting situation, the substrate 1 is cut. When 1 is cut, the substrate 1 is cut at an intermediate position of the inclined surface 13, and a chamfered portion 15 constituted by the inclined surface 13 is formed on one side with the cut surface 11 as a boundary. , on the other side, there is formed a hooking part 16 which is inwardly cut into a groove shape by the inclined surface 13 and the face 12.
By setting the 6th side to the back side, the brick body 5.5a, which is provided with the chamfered part 15 and the hooked part 16, can be molded by only - times of cutting operations.

After cutting, each brick body 5.5a... is subjected to a drying process and a firing process according to the usual method, and then the chamfered part 15 and the hanging part 1 are formed.
This results in a brick product with 6 features.

In short, the present invention has a chamfered part 15 formed on the ridgeline part on the front side of the brick body 5.5a, and a hook part 16 cut inward in the shape of a groove on the peripheral edge part on the back side. Since the chamfered portion 15 is exposed on the surface side when the brick body 5.5a... is constructed, the chamfered portion 15 is exposed when used as a paving member for a sidewalk, for example. In addition, the chamfered portion 15 emphasizes the geometric pattern and improves its commercial value.On the other hand, on the back side, the hooking portion 16 is placed under the buried material such as cement. Since it is held in the cut shape, it is possible to perfect the adhesion of the brick body 5.5a and completely prevent troubles such as misalignment and peeling after construction.

Moreover, a brick body 5 having such a chamfered portion 15 and a hooking portion 16 is provided.
．． 5a... is a wedge-shaped engraving blade with a single taper on the circumferential surface portion of the base material 1 to be cut when cutting the base material 1 extruded from the extrusion molding machine 2 into a single brick body 5.5a... 8.Press 8a... to face 1 parallel to the cut surface
2 and an inclined surface 13 are provided around the circumference, and a cutting tool 9 is inserted at an intermediate position of the inclined surface 13 of the transfer groove section 14.
．． 9a... transforms the base 1 into a single brick body 5.5a.
Since the brick body 5.5a... is cut in such a manner that the chamfer 15 is formed on the front side of the brick body 5.5a and the hooking portion 16 is formed on the back side of the brick body 5.5a at the same time, the brick body 5.5a is cut at the same time. Moreover, if the cut surface 11 is within the slope 13 of the groove 14 cut in advance, even if the cutting position is slightly shifted from side to side, it will hardly affect the chamfer 15 formed on the circumferential surface. Its practical effects are enormous, such as being able to form a beautiful chamfered portion 15 that does not require finishing in subsequent steps without causing any damage.
