[0003]

In the former case, the number of steps is large, the labor and time are long, the work on the external scaffold is large, and the risk rate is high. Further, there is a problem in the adhesiveness of the tile and the concrete for tile foundation. In the latter case, the number of steps is small and the construction period can be shortened and labor can be saved, but the Omnia plate is heavy and requires a large heavy machine. High reliability for peeling due to tile driving, but it takes time to set tiles.

The present invention has been proposed in view of the above problems of the prior art, and the purpose thereof is to mainly formwork and tile construction among construction works for cast-in-place concrete. The point is to provide a construction method that saves labor for the outer wall finishing work.

[0005]

In order to achieve the above object, according to the construction method of the present invention, which uses a cement extrusion molding plate that also serves as a formwork, a rectangular main plate has locking portions at the top, bottom, left and right. Then, tiles for mounting tiles are lined up on the outer surface, and the tiles are preliminarily mounted on the outer surface of each cement extruded molded plate on which the protruding ridges for the separator mounting metal fittings are arranged on the inner surface. While assembling each molding plate as an outer frame, lock the separator mounting metal fittings between the inner protruding ridges of each molding plate, adjust the building of the molding plate, and arrange the wall reinforcing bars. Built in the inner side formwork, connecting concrete at a predetermined interval through the separator attached to the separator mounting bracket, and pouring concrete, after curing the pouring concrete, removing the inner formwork is there.

[0006]

According to the present invention, the cement extrusion molding plate which also serves as a formwork can be easily installed vertically and horizontally by utilizing the locking portions provided on the upper, lower, left and right sides of the molding plate. The gap is prevented and the watertightness of the horizontal joint is improved. Further, the metal fittings for the separator are easily locked by the inner protruding ridges of the forming plate, and the installation adjustment of the forming plate is performed. Further, the molded plate is built by the separator attached to the separator mounting bracket so that it can be maintained at a constant distance from the inner mold, and the separator mounting bracket mounting protrusion is used to drive the molded plate. Adhesion to concrete is enhanced.

Furthermore, by installing the tiles in advance between the protruding ridges provided on the outer surface of the main plate of the molding plate, it is possible to save labor in the tile attaching work.

[0008]

The present invention will be described below with reference to the illustrated embodiments. P is a cement extrusion molded plate that also serves as a mold frame, and 1 is a rectangular main plate that constitutes the main body of the molded plate. Engagement ridges 2 and engagement recessed grooves 3 that are engaged with each other are provided on the upper and lower end surfaces, respectively. A horizontal rib 4 for mounting a horizontal tile is provided on the outer side surface.

Further, vertical protruding ridges 7 having engaging protruding ridges 5 and engaging recessed grooves 6 are provided on both right and left sides. The projecting ridges 2 and 5 and the engaging recessed grooves 3 and 6 constitute upper, lower, left and right engaging portions of the rectangular main plate 1. Further, horizontal projecting ridges 8 and 9 for mounting the mounting bracket for the separator are provided along the upper and lower edges of the main plate 1.

Then, the rectangular main plate 1 of the cement extrusion molded plate P which also serves as the formwork of the first stage is fitted with the engaging protruding ridges 5 and the engaging recessed grooves 6.
The vertical reinforcing material Q between the protruding ridges that are vertically installed
And the adjacent molding plates P are set. Next, the adjacent molding plate P is set, the metal fittings 10 for mounting the separator are set on each of the projecting ridges, and the fitting adjustment is performed using this.
The separator mounting bracket 10 is a separator mounting bracket according to the applicant's application (Japanese Patent Application No. 4-871).
4) is used. The vertical reinforcing material Q is attached before or after the extruded plate P is built.

Since the lowermost molding plate P has a large casting concrete pressure, an intermediate protruding ridge 8'is provided as shown in FIGS. 8 and 9, and the protruding ridge 8'is provided with the metal fitting for the separator. 10 is attached. Repeating the above construction first
Set the corrugated plate. Next, the rectangular main plate 1 of the second-stage forming plate P is built through the engaging protruding ridges 2 and the engaging concave groove 3 and the vertical reinforcing material Q is inserted in the same manner as in the above case, and the adjacent The forming plate P is set, and then the second-stage forming plate is set.

Then, a metal fitting 10 for mounting a separator is attached over the horizontal protruding ridges 8 and 9 of the first and second forming plates to fix the first and second forming plates. Next, the first vertical reinforcement Q is fixed at the joint position, and the above steps are repeated to assemble the external formwork. (See FIG. 10) Note that tiles T are attached in advance between the horizontal ribs 4 for attaching tiles on the outer side surface of each molding plate P.

Next, the inner side formwork 12 assembled on the lower concrete slab 11 and the rectangular main plate 1 are connected at a predetermined interval via a separator 13 mounted on the separator mounting bracket 10. The mold frame is assembled via the end piece 14, the mold clamp 15 such as a foam tie. (See Figure 11)

[0014]

As described above, according to the present invention, concrete is produced by using a cement extrusion molding plate in which projecting ridges are provided on the inner surface of a rectangular main plate having locking portions on the top, bottom, left and right as a formwork. Since the construction is carried out, it is possible to reduce the labor required for removing the external formwork from the formwork work, and the molding plate is reinforced by the projecting ridges to improve the adhesion to the pouring concrete. Further, through the protruding ridges, it becomes possible to mount the separator mounting metal fittings and adjust the installation of the molded plate by the metal fittings.

Further, since the tile mounting ribs are provided in a row on the outer side surface of the molded plate, it is possible to save the labor of the tile attaching work, particularly the tile attaching work in the factory.
