Field of the Invention The present invention relates to a method for manufacturing paving blocks for paving roadways and sidewalks side by side. 2. Description of the Related Art A pavement block in which a rubber plate having a rectangular planar shape is fixed to the upper surface of a concrete base layer having the same shape with an adhesive is known from Japanese Patent Application Laid-Open No. 5-285914. In the above-mentioned conventional block, a rubber plate is adhered to the upper surface of a concrete base layer. However, since the adhesive strength between the rubber and concrete is low, automobiles such as intersections are frequently used. When paving side by side on the road where left and right turns, the tires of the left and right turning cars rub against the rubber plate with the frictional force of uneven load, and the rubber plate comes off from the concrete base layer. In addition, since the surface of the rubber plate is flat, the snow falling on it in cold regions is compacted by the tires of the car, making it extremely slippery, and the car slips, causing accidents or crossing. Pedestrians fall and get injured. SUMMARY OF THE INVENTION The present invention relates to a method for manufacturing a paving block which has been developed to solve the above-mentioned problems of the conventional concrete block for paving. On one side of the metal plate to fit, create a groove parallel to the surface
Thereby bonding the rear surface of the rubber slab having multiple, the surface of the other side, at least one hole vertically fixing the metal plate anchor having, die hole of the mold and the metal plate was rubber plank down Into the mold hole under the vibration of the mold, and then press the inside of the mold hole from above to harden the concrete, and at the same time, press the rubber thick plate, metal plate, It is characterized in that the layers are integrated and removed from the mold. [0005] In the illustrated embodiment, 1 is a metal plate plate, 2 is a metal plate anchor fixed vertically to its lower surface, several holes 3 are opened in the anchor. . Metal plate 1 and metal plate anchor 2 are made of iron plate,
The metal plate 1 has a thickness of, for example, 2.5 mm, and the planar shape is a rectangle having a long side of about 200 mm and a short side of about 100 mm. The anchor 2 is made of a metal plate having a thickness of 3 mm, and is welded downward to the lower surface of the metal plate plate along the long side in such a manner as to bisect the metal plate plate. The anchor 2 has a downward length of about 40 mm, has two semicircular notches 4 at both ends, and has two holes 3 at equal intervals between the notches at both ends. The diameter of the two holes 3 and the diameter of the two notches 4 at both ends is about 30 mm. Reference numeral 5 denotes a rectangular rubber thick plate of the same size fixed on the metal plate plate 1 with a strong adhesive, and has a thickness of about 1 mm.
5 mm. The rubber material of the thick rubber plate is a mixture of natural rubber and synthetic rubber, which has high wear resistance and excellent tear strength. A large number of grooves 6 having a groove width of about 7 mm and a depth of about 7 mm are provided in parallel on the upper surface of the rubber thick plate at intervals of about 10 mm. The groove 6 has an angle α of about 60 ° with respect to the long side of the rubber thick plate.
However, this angle is arbitrary. [0007] Reference numeral 7 denotes a rectangular rectangular base having the same size as the metal plate and having a thickness of about 65 mm, which is formed by burying the anchor 2 of the metal plate and fixing the metal plate on the upper surface. Since the concrete 8 of the base layer 7 fills the holes 3 and the notches 4 of the buried anchor 2 and is solidified, the mounting strength between the metal plate 1 and the concrete base layer 7 is extremely large. To form the pavement block, a rubber thick plate 5 is bonded with an adhesive to the upper surface of the metal plate plate 1 on which the anchor 2 is fixed, with the groove 6 facing upward, and as shown in FIG. The rubber thick plate 5 is placed on a pallet 13 which covers the bottom of a mold hole 12 penetrating up and down of a mold 11 for molding 7, and the hardened concrete having a slump value of 0 is placed in the mold hole 12 where the anchor 2 stands. 4 is charged under a vibration by vibrators 14 and 14, and then, as shown in FIG. 4, while continuing the vibration, the press device 15 is lowered and the concrete in the die hole is pressed by the press plate 16 at the lower end. Pressing the metal plate and rubber plate to increase the density of the concrete, make the height of the product as specified, then stop the vibrator, lower the pressing device as shown by the broken line, and , Pallet 13 also descends simultaneously demolded product on the pallet. In the illustrated embodiment, the plane shape of the metal plate, the rubber plate, and the concrete base layer is rectangular, and the road is 1 m long.
Although the number of laying per two is set to 40, the plane shape and size are arbitrary. [0010] For bonding rubber and a metal plate, a strong adhesive that does not peel off the rubber from the metal plate is commercially available (Chemlok, brand name Far far).
East Inc. ). Since the thick rubber plate 5 of the pavement block of the present invention is adhered to the upper surface of the metal plate 1 by such an adhesive, it is laid at intersections or the like, and the tire of the automobile is rubbed by the frictional force of the uneven load. Even if the plate is rubbed, the rubber plate will never come off. The metal plate 1 is fixed to the upper surface of a concrete base layer 7 by embedding a metal plate anchor 2 vertically fixed to the lower surface in a concrete base layer 7. A plurality of holes 3 are formed in the anchor, and the concrete 8 of the base layer fills the holes 3. Therefore, the mounting strength between the metal plate 1 and the concrete base layer 7 is very high. The rubber plate 5 has a number of parallel grooves 6 on the upper surface. The groove 6 serves as a non-slip for tires of automobiles and pedestrians 'shoes, and when the snow falls and freezes in winter, the ridge 6' separates the grooves 6 with an uneven load received from the tires of the automobile running thereon. Deforms and presses and crushes the snow clogged in the groove 6 due to the elasticity and distortion of the rubber, and pushes the snow out of the groove. Accordingly, the snow layer on the rubber thick plate is easily peeled off and crushed, so that it is not slippery and does not enter into a dangerous snow compaction state or a frozen state. This can prevent a car slip accident and a pedestrian falling accident. Furthermore, the concrete can be filled in the mold cavity, compressed with a pressing device, and mass-produced by an immediate demolding method.
