Description

  The present invention relates to a mold for producing a tiled outer shell PCa member by pouring concrete.

  When building a building with a tiled finish, a tiled outer shell PCa member with a tile previously stuck on the surface may be used. When the tiled outer shell PCa member is manufactured using the manufacturing formwork apparatus, the tiles are prevented from peeling off by embedding the driven tile in the concrete of the outer shell PCa member by the tile attaching method. When an outer shell PCa member having a hollow portion is manufactured using a manufacturing formwork apparatus, concrete is cast from above the manufacturing formwork apparatus configured by an outer formwork having a concave cross section, an inner formwork, and a small-end formwork. Has been established. In the case of a normal outer shell PCa member that does not have a tip tile, an inner mold frame that forms a hollow portion is installed above the bottom surface of the outer mold frame while ensuring the thickness of the outer shell PCa member, and then has a concave outer section. A side mold of the mold is installed, or the inner mold is hung from the upper side to the inner side of the outer mold and arranged at a predetermined position to assemble the production mold apparatus (see Patent Document 1). However, in the case of the tiled outer shell PCa member, since the driving tile is attached in advance to the inner surface of the outer mold, the inner mold cannot be installed in advance. Further, when the inner mold is suspended, the inner mold may come into contact with the driving tile or joint material on the inner surface of the outer mold, and the driving tile or the like may be peeled off or damaged. Such peeling or breakage of the driven tile or the like is likely to occur in the case of the outer shell PCa member that needs to be placed with the driven tile on the inner surface of the outer mold and the inner mold close to each other.

On the other hand, as shown in FIG. 5, one side surface portion 101 of the outer mold frame 100 to which the driving tile or the like is attached is moved outward to ensure a wide space between both side surfaces, and in this state, the inner mold frame 102 is placed at a predetermined position in proximity to the other side surface portion 103 that is fixed, and then the one side surface portion 101 moved outward is moved to a predetermined position to form an outer mold frame having a concave cross section. Thus, the contact between the inner tile 102 and the driven tile on the inner surface of the outer mold 100 is prevented.

It is formed with an inclination angle in a gap with the outer periphery of the inner mold 3.

  The operation of the manufacturing form A of the tiled outer shell PCa member according to the present embodiment will be described following the procedure for manufacturing the tiled outer shell PCa member. On the upper surface of the steel work table 13 for manufacturing the PCa member, the left and right horizontal frame portions 10 are installed vertically with their inner surfaces facing each other in parallel. The distance between the left and right horizontal frame portions 10 is set equal to the width of the PCa member. The horizontal frame 10 is fixed to the steel work table 13 with bolts and nuts 35 and attached to the steel work table 13. Thereby, the outer mold frame 1 having a concave cross section is formed.

  A driving tile 4 is attached to a predetermined position of the inner surface 1b of the outer mold 1 fixed on the steel work table 13 by using a double-sided tape or an adhesive, and a joint material 5 is arranged between the driving tiles 4. To do. The first fore edge formwork part 20 is attached to the end part 1a of the outer formwork 1 after the placement of the driving tile 4 is completed. The first fore edge formwork portion 20 is fixed to the inner surface of the horizontal formwork portion 10 of the outer formwork 1 by mounting bolts and nuts 34. The inner end surface 20 a of the attached first fore edge mold part 20 protrudes inward of the outer form frame 1 rather than the driving tile 4. An opening having the same shape as the outer shape of the second fore edge mold part 21 is formed by the first fore edge mold part 20 at the end 1a of the outer form 1 at the stage where the first fore edge form part 20 is attached. Is done.

  On the other hand, the assembly of the inner mold 3 and the attachment of the second fore edge mold part 21 are performed before or after or in parallel with the assembly of the outer mold 1 and the attachment of the first fore edge mold part 20. First, round-shaped reinforcing bars 7 are arranged at predetermined intervals around a steel mold member 6 constituting the inner mold 3 while being supported by temporary reinforcing bars 15. After that, the second fore edge mold part 21 is attached by contacting both ends 3a of the inner form frame 3, that is, both ends of the form member 6, and the end of the temporary reinforcing bar 15 is passed through the second fore edge form frame part 21. To support. The second small edge mold part 21 is attached so that the outer periphery of the inner mold 3 does not protrude from the outer periphery when viewed from the end of the inner mold 3. The second fore edge mold part 21 projects the end of the assembly bar 16 penetrating the inside of the form material 6 from the assembly bolt hole of the second fore edge mold part 21, and the nut 33 forms the inner form frame. 3 is fixed to both ends 3a. By this fixing, the second fore edge mold part 21 and the inner form frame 3 are integrated, so that the second fore edge mold part 21 installs the inner form frame 3 inside the outer form frame 1 and a guide Become.

  Next, the inner mold frame 3 to which the second fore edge mold part 21 is attached is lifted and moved to the upper side of the outer mold frame 1, and then the inner end surfaces 20 a of the left and right first fore edge mold parts 20, 20, Between 20a, it inserts, aligning the left and right side surfaces 21a, 21a of the second fore edge mold part 21.
