Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a conventional method for finishing the rough outer wall of a reinforced concrete building, in which plywood or iron plate formwork for concrete formwork is exclusively used, and in particular, the panel material can be used repeatedly about three times. In addition, labor costs and curing costs are required, as is the use of peeling agents when removing formwork such as iron plates, etc., and the consumption of materials is enormous. Furthermore, the outer wall after the formwork is removed has a rough surface and requires an intermediate coat and a finishing mortar wall coat.

In the present invention, by using asbestos cement board as a formwork, which is comparable to the conventional concrete IJ-Gt external wall, the work of removing the formwork is eliminated, and in addition, the finished wall of the asbestos slate board external wall or the rough surface wall with tile coating is used. Regarding construction methods.

Figure 1 shows a perforated flexible plate used in the present invention. Figure 111 of 11 (1) is +2 on the flexible board.
1 is a through hole, and FIG. 2 is an external view. According to experiments, asbestos boards used as formwork can be used for pouring fresh concrete 11.
7, we adopted a plate with enough rigidity to withstand the lateral pressure, but
The disadvantage of this board is that the contact surface is smooth, so its compatibility with fresh concrete (I/1) is not necessarily good, so a structure was developed to improve its adherability. For this purpose, by appropriately selecting the dimensions and pitch of the through holes,
While minimizing the leakage of fresh concrete through the through hole, the through hole was filled with fresh concrete mortar and solidified to form an adhesive scaffold.

At the same time as this adhesive scaffold is formed, the air and moisture in the fresh concrete are properly discharged through the through holes (2), which has the side effect of preventing the formation of slabs. This not only shortened the time it took to finish the concrete wall, but also improved the mechanical strength of the concrete.

Furthermore, after pouring fresh concrete into the formwork according to the present invention and observing the solidification time of the concrete, scraping off the mortar seeping out from the through holes with a trowel and washing the surface of the mold board with water, the finished surface of the concrete wall is comparable to that of concrete walls. Once the exterior wall is completed, a synthetic resin paint is applied to it to finish the exterior wall. Furthermore, if the mortar seeped through the through holes is left uncirculated, the wall surface will be finished as a wall suitable for pasting tiles, etc., and the effect of providing the through holes according to the present invention is significant. be.

Claims (1)

[Claims] In form work for RC and SRC buildings, through-holes of appropriate diameters are provided at appropriate intervals in asbestos slate boards, and the asbestos slate boards are used as formwork and connected to structural reinforcing bars with support columns and beams, etc. External wall finishing method for reinforced concrete buildings in which fresh concrete is poured between the formwork and after the concrete solidifies, the asbestos slate plate formwork is used as the external wall surface wall without removing it.
