JP2016211161A - Preform material, and metallic mold for forming roof tile basis material from preform material - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a preform material and a roof tile basis material that may be volume-produced readily and overcome problems with conventional two-component preform material comprising a ceramic roof tile body and a cover body with an opening for inserting a wire that covers a hole, a wall piece and a cutoff wall piece formed on the ceramic roof tile body, the problems including a large amount of labor and time needed for assembly and burdens regarding work arrangement, preparation, stock management and other management work.SOLUTION: A preform material of a wiring roof tile includes a tunneled preform material having a conduit pipe insertion hole formed on a roof tile body preform material pierced with a through-hole, and a blocked insertion hole formed on the tunneled preform material by pressing in a side of the roof tile body with the tunneled preform material cut in and off, and the through-hole and the insertion hole are communicated. The configuration allows the preform material of the wiring roof tile to be formed as an integrated product and the structure to be secured. The preform material as an integrally formed product is manufactured by means of adjusting a clay property and a water content, adding oil and a release agent, and coordinating manufacturing processes.SELECTED DRAWING: Figure 2-3

Description

  The present invention relates to a special roof tile such as a wiring roof tile for solar power generation, a snow melting roof tile or the like, a rough ground of a normal roof tile (in some cases), and a mold for molding a roof tile from the rough ground.

  Conventionally, with regard to the waste of the wiring tile, and a mold for forming the tile base from the waste, there is a one-piece production by hand, and “wiring tile” described in Japanese Patent Application Laid-Open No. 2011-208446 proposed by the present applicant. The present invention is mounted on a ceramic tile body provided with a hole for wiring insertion, an inverted U-shaped wall piece surrounding the buttocks around the hole, and a water blocking wall piece. The structure is composed of two parts: a hole, a wall piece and a water blocking wall piece, and a cover body provided with an opening for wiring insertion. Therefore, it is easy to manufacture wasteland and tiled body and is suitable for mass production. However, it can be considered that it takes time and labor to assemble the ceramic tile body and the cover body. In addition, it is a two-part, requiring labor and control in preparation for setup, mechanism, inventory management, etc., which is cumbersome and requires careful attention to the relevance of each work. There is room.

  In FIGS. 1-1 to 1-4, 1 is a basic form of wasteland extruded from a drain machine (not shown), and houses the tile body wasteland 100 having a thickness and the cable 200 or the cable 200, And it is comprised with the tunnel wasteland 102 provided with the thickness which has the insertion hole 101 into which the electric conduit 2 to protect or the PF pipe is inserted. Cut the notch 3 into the bottom side A of the tunnel wasteland 102 (when laid, the same applies hereinafter) and cut it. In this example, it is a cut-off shape, and is inclined from the upper butt side A of the tunnel wasteland 102 toward the lower head side B of the tunnel wasteland 102 (see FIG. 1C). Moreover, the through-hole 5 is formed in the tile main body rough ground 100 so that it may connect with the head side B of this lower sky. For that purpose, the meat of the part is removed.

  In FIGS. 2A and 2B, and FIGS. 5A and 5B, the basic form 1 of the wasteland is set on the upper and lower molds 10 and 11. The lower mold 11 is provided with a bulging core 1100 for securing the through-hole 5 and withstanding the pressing of the cut-off side 102a of the tunnel waste land 102 and securing a semi-cylindrical surface. Further, the upper mold 10 is formed with a concave groove 1000 (a space portion) that forms a cavity space H that receives the roof tile body 100 by forming a curved surface (a semi-cylindrical surface of the tunnel 20) by pressing the cut-off side 102a. ). The cavity space H is a space formed between the concave groove 1000 of the upper mold 10 and the surface 1101 of the lower mold 11. Further, the upper mold 10 is provided with a press machine 1002 for moving an insertion core 1001 inserted into the tunnel wasteland 102.

  The operation of the upper and lower molds 10 and 11 will be described with reference to FIGS. 2-1 to 2-3. FIG. 2-1 shows a state in which the upper and lower molds 10 and 11 are opened, and proceeds to the next. That is, as shown in 2-2, the bulging core 1100 of the lower mold 11 is inserted into the through hole 5 of the roof tile wasteland 100, and the basic form 1 of the wasteland is set in the lower mold 11. And the upper mold | type 10 provided with the press machine 1002 falls. The concave groove 1000 of the upper die 10 covers the tunnel wasteland 102, and the lower surface (back surface) of the upper die 10 contacts the roof tile wasteland 100. As a result, the tunnel wasteland 102 is accommodated in the cavity space H, and the cut-off side 102a of the tunnel wasteland 102 includes the semi-cone-shaped surface 1100a of the bulging core 1100 and the narrowed semi-cone-shaped surface 1000a of the recessed groove 1000. Thus, it narrows down to a semi-cylindrical shape and closes the bottom side A of the tunnel wasteland 102.

  The tunnel wasteland 102 is accommodated in the cavity space H, and the upper and lower molds 10 and 11 are combined, and the cut-off side 102a is narrowed down into a semi-cylindrical shape and the bottom side A of the tunnel wasteland 102 is closed (blockage). The insertion hole “refer to FIG. 2-3”) and the press machine 1002 are driven, and the insertion core 1001 enters the through hole 5 of the tunnel wasteland 102 to form the tunnel 20 of the roof tile 30. . At this time, uniform movement of the clay to the tunnel 20 is achieved, and uniform movement of the tile body 21 to the lower vicinity of the tunnel 20 is achieved. Therefore, there is an actual benefit that is useful for improving the strength of the tile base 30 and / or the tunnel 20 and improving the quality of the wiring tile 40. In the figure, 13 is a vent for the upper die 10.

  Note that the release of the tile base 30, the release of the upper and lower molds 10 and 11, and the return of the press machine 1002 are the reverse operations described above.

  FIGS. 3A and 3B show a structure in which the cut-off side 102a of the tunnel waste land 102 is a straight line shape in the basic form 1 of the rough land, and the straight line shape is similar to the cut-off side 102a of the aforementioned cut-off shape. .

  In the enlarged schematic cross-sectional view showing the use state of FIG. 6, the conduit 2 into which the cable 200 is inserted is inserted and supported in the tunnel 20 of the wiring tile 40 manufactured by firing the tile base 30 and applying glaze. The cable 200 accommodated in the conduit 2 is guided to the lower side of the base plate 42. In the figure, reference numeral 41 denotes a roof tile.

  The above description is about the flat roof tile, but the same applies to the Japanese shape shown in FIG.

  Each structure described above is a description of a preferred example of the present invention. Therefore, the present invention is not limited to the above-described embodiments, and structures that change a part of the configuration within the scope of the invention, structures that can achieve the same features and effects, and the like are within the scope of the present invention. It is.
