Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a press mold for pressurizing a hard concrete material filled in a mold body to manufacture a curb block having a three-dimensional pattern of unevenness on at least a side surface.

[0002]

[Prior art]

 The applicant of the present invention enters a hard kneaded concrete material filled in the inside of a mold body having an open upper surface from the open upper surface of the mold body and pressurizes it to form a hard kneaded concrete material into a curb block. A press die for manufacturing blocks has been proposed in JP-A-3-290205.

[0003]

[Problems to be solved by the device]

 The press die proposed above has an upper horizontal surface and a downward slope that descends at an obtuse angle from the upper horizontal surface.The upper horizontal surface and the downward slope press the hard kneading concrete material filled in the mold body. However, since both the upper horizontal surface and the down slope are smooth, it is not possible to express an uneven three-dimensional pattern on the manufactured curb block.

[0004]

[Means for Solving the Problems]

 In view of this, the present invention provides an uneven pattern expressing portion on at least the down slope of the above-mentioned press mold so that a curb block having an uneven three-dimensional pattern on the side surface can be formed.

[0005]

【Example】

 In the illustrated embodiment, reference numeral 1 is a form main body, which is closed on four sides, has an upper surface 2 and a lower surface 3 open, and has a lower surface closed by a pallet 4 mounted on an elevator 5 moving up and down. Reference numeral 10 denotes a press type, which includes an upper surface plate 12 having an upper horizontal surface 11 on the lower surface and a side plate 14 having a downward slope 13 that descends at an obtuse angle from the upper horizontal surface 11. In this embodiment, the upper horizontal surface 11 and the downward slope surface 11 are provided. An uneven pattern expressing portion 15 is provided on both of the portions 13.

Since FIG. 1 is a press die for manufacturing a curb block having an uneven three-dimensionally patterned side surface on one side (FIG. 3A), the side plate 14 is an inverted L shape that hangs down from one side of the top plate 12. However, in the case of a press die that manufactures a curb block that has concave and convex three-dimensionally patterned sides on both sides, as shown in Fig. 2, two side plates have an inverted U-shape that hangs from both sides of the top plate. Become. In the case of the inverted L-shaped press die shown in FIG. 1, the outer surface 14 'of the side plate 14 behind the descending slope 13 and the other side 12' of the upper plate are opposite inner surface 1a in the mold body, 1b (see FIG. 1a), and in the case of the inverted U-shaped press die of FIG. 2, the outer surfaces 14 ', 14' of both side plates are opposite inner surfaces 1a, 1b in the mold body. It goes up and down along the line (see Fig. 2B).

In order to manufacture a curb block, the mold base 1 is filled with a hard-mixed base layer material A containing concrete (FIGS. 1B and 2B), the press mold is lowered, and its upper horizontal surface 11 is The material A is compressed by the descending slope 13 and the lower end of the side plate 14 is lowered to near the pallet 4 (primary pressing step, FIGS. 1C and 2C). When the press die is lifted after the compression is completed, a space 6 left after the press die is compressed is formed in the mold body. Therefore, the hard surface layer material B containing the mortar containing the decorative material and the pigment is filled therein (Fig. 1D, Fig. 2D), and then the press die is lowered again to compress the surface layer material B and the base layer material A in the mold body so that the surface layer material having a required thickness becomes integral with the base layer material, and A curb block with three-dimensional patterns of unevenness on the upper and side surfaces is molded in the main body of the mold by the upper and lower horizontal surfaces and the unevenness pattern expressing portion 15 on the down slope (secondary pressing step, FIG. 1e, FIG. 2e). ). In this way, when the curb block is formed by lowering and stopping the press die to a predetermined position, the press die and the elevator 5 are simultaneously lowered, as shown by broken lines in FIGS. 1 (e) and 2 (e). The curb block is removed from the surface pallet 4 mounted on the elevator.

In this embodiment, in addition to the side surfaces, a curb block having an uneven three-dimensional pattern is also formed on the upper surface. However, the uneven pattern expressing portion is provided only on the downward slope of the press die, and there is no uneven pattern on the upper surface. It is also possible to form a curb block having an uneven pattern only on the side surface.

[0009]

[Effect of device]

 If the side face of the curb block is perpendicular to the top face, even if the press die that molds the side face is provided with an uneven pattern expression part, the uneven shape expression part is raised and lowered by the press die. It is not possible to create an uneven pattern on the vertical side surface simply by rubbing the side surface. However, since the side surface of the block of the present invention is formed by the downward slope having an obtuse angle with respect to the upper horizontal surface, by providing an uneven pattern expression portion here, an uneven three-dimensional pattern as the pattern expression portion is formed. It can be expressed on the side of the curb block. Therefore, when the surface of the block is decorated with the surface material, it is possible to manufacture a very attractive curb block in which the decoration effect of the surface material and the decoration effect of the uneven three-dimensional pattern are combined.
