The rising wall formwork apparatus 1 shown in FIG. 1 and FIG. 2 is a rising wall formwork used when building up a rising wall 30 that rises on the slab concrete 20 when building slab concrete of a building. An embodiment of the device 1 is shown.

  As shown in FIG. 2, the rising wall mold apparatus 1 has a rising wall 30 on the upper surface of a slab mold 2 installed by means not shown in parallel with the arrangement of the slab reinforcing bars 10 a and the rising wall reinforcing bars 10 b. A necessary number of lower flat bars 4 are arranged and fixed at an interval of, for example, about 300 mm to 600 mm in the longitudinal direction. And, the nut 6a, 4a fixed to the both sides of the upper surface of the lower flat bar 4 is erected by screwing the lower end of the bolt 6 with the sheath tube, and the upper flat to the upper part of the bolts 6, 6 with the sheath tube on both sides. Bars 5... Are installed (or stretched) substantially horizontally and positioned at a desired height position. A pair of left and right rising wall molds 3, 3 are placed and fixed on the upper flat bar 5, and a necessary number of width stoppers 7 are attached to the upper end of the rising wall mold 3.

  The lower flat bar 4 is a flat iron plate having a thickness of about 6 mm, a length obtained by adding about 80 mm to the width of the rising wall, and a width of about 30 mm. The nail holes are fixed to the upper surface of the slab form frame 2 by nail clamps 2a and 2a. The nuts 2a and 2a fixed to the upper surface of the lower flat bar 4 are joined by welding to the installation position of the raised wall mold 3 that has been marked. The surface of the lower flat bar 4 is rust-prevented.

  The bolt 6 with the sheath tube is inserted into the vinyl chloride sheath tube 6a having a length slightly shorter than the thickness (about 300 mm) of the slab concrete 20 and a bolt 6b slightly longer than the thickness of the slab concrete 20 is inserted. Configured. The lower nut 4b screwed from the upper end of the bolt 6b in order to position the upper flat bar 5 is screwed into the bolt 6 with the sheath tube until the upper surface thereof is flush with the upper surface of the sheath tube 6a. . Since the bolt 6b is partitioned from the concrete by the sheath pipe 6a, after the rising wall is constructed, it can be extracted from the sheath pipe 6a and diverted.

  The upper flat bar 5 has, for example, the same shape and the same size as the lower flat bar 4, and holes through which the bolts 6 b of the bolts 6 with the sheath tube are passed are formed at both left and right ends. After the bolts 6b and 6b are passed through the holes on both sides, the bolts 6b and 6b are placed on the lower nut 4b which is fixed first, and the height is positioned.

The rising wall molds 3, 3 are made of aluminum, and the cross-sectional shape viewed from the front is substantially L-shaped. For example, the dimensions of the rising wall 3 are about 900 mm in the depth direction and the height is about 500 mm. The rising wall mold 3 is formed with a mounting seat 3a bent at about 90 degrees outward at the lower end, and the bolt 6b is passed through the bolt through hole provided in the mounting seat 3a to The upper nut 4c, which is screwed from the upper end of the bolt 6b, is fastened and firmly fixed together with the upper flat bar 5.

By placing the slab concrete 20, the concrete is cast and constructed with the rising walls 30 rising on the slab concrete 20 at the same time.
The rising wall formwork apparatus 1 includes the slab molds 2, 2, the upper and lower flat bars 4, 5... And the sheath pipe 6 a embedded in the slab concrete 20 and the rising wall 30. After the wall 30 is constructed, the other rising wall mold 3, the bolt 6b extracted from the sheath tube 6a, the upper nut 4c screwed into the bolt 6b, and the width stopper 7 can be recovered and diverted. Can contribute to cost reduction. Therefore, it can be effectively implemented especially in a high-rise building where the number of diversions is large. In addition, the aluminum rising wall mold 3 is lightweight and easy to process, and can be used more frequently than a wooden rising wall mold, reducing the amount of industrial waste.

Although illustration is omitted, it is also preferable that an angle member or a pier is installed as a reinforcing material on the excavated ground, and the discarded concrete 8 is constructed thereon.

The lower flat bar 4 is fixed to the upper surface of the discarded concrete 8 at two positions in the central portion by nailing with concrete nails 8a and 8a using previously provided nail holes.
The base mold 9 is made of aluminum, and the cross-sectional shape viewed from the front is substantially inverted L-shaped, and a bolt through hole is previously formed in a flange portion 9a formed by bending the lower end portion outward by about 90 degrees. The bolt through hole is connected to the lower flat bar 4 by welding or the like, and is passed through the bolt 11 which is raised, and a nut 12 screwed from the upper end of the bolt 11 is tightened. It is fixed. The upper end 9b bent inward of the base mold 9 is placed on the upper flat bar 5, and together with the rising mold 3 placed on the upper end 9b of the base mold 9, a sheath tube is attached. The upper nut 4c screwed from the upper end of the bolt 6 is fastened and fixed. An air vent hole 9c is provided in the upper end portion 9b of the base mold 9 to prevent air accumulation when placing concrete.

Therefore, in the case of this rising wall formwork apparatus 1 ′, the concrete is cast into the same formwork 3 from the middle upper surface opening of the width stoppers 7 and 7 attached to the upper end of the rising wall formwork 3, thereby providing the base concrete. Simultaneously with the construction of 90, the concrete is cast and constructed with the rising wall 30 rising on the base concrete 90.
Although not shown in the figure, the rising wall molds 3 and 3 are arranged on the outside with piers or the like so as not to fall down by concrete pressure when placing concrete from the upper end opening of the rising wall mold 3. It is preferable to support. Of course, it is also preferable to implement the rising wall mold apparatus 1 of the first embodiment described above in a configuration in which the rising wall molds 3 and 3 are supported by a crosspiece or the like.

  In the rising wall formwork apparatus 1 ′, the upper and lower flat bars 4..., 5 ... and the sheath pipe 6a are buried in the base concrete 90 and the rising wall 30 among the constituent elements. , 9, rising wall molds 3 and 3, bolts 6 b extracted from the sheath tube 6 a, upper nuts 4 c screwed into the bolts 6 b, bolts 11 and nuts 12 for fixing the base mold 9 to the lower flat bar 4, and The width stoppers 7 can be collected and reused, which can contribute to cost reduction.
