る。(Prior art) Cracks are generally unavoidable in the framework of reinforced concrete buildings, but one of the causes of cracks that occur in concrete exterior walls is drying shrinkage of wall concrete and drying shrinkage of shaft material (columns, beams) concrete. Because the former is larger than the latter, the drying shrinkage strain of the wall concrete is restrained by the shaft material. The shrinkage stress state of the wall becomes compressive in the vertical direction due to its own weight, etc., and the tensile stress due to the difference in drying shrinkage is cancelled, but in the horizontal direction, this tensile stress remains as it is, and generally the wall is compressed in the vertical direction. Cracks occur.

接PC板に伝播させない性質を有するものである。 The PC board 2 is made of fiber-reinforced concrete using glass fiber, carbon fiber, plastic fiber, etc. As shown in Figures 2 and 3, ribs 2a are provided on the inner surface of the PC board 2 in the horizontal direction and across the entire width, with two ribs in the middle part of the PC board and one each in the upper and lower end sides. A total of four books are placed protruding at equal intervals. The opposite side of each rib 2a is
It has a tapered surface that slopes toward the space between the ribs.
The spacing between the ribs 2a is determined taking into account that the PC board 2 will not be deformed by the lateral pressure during concrete pouring of the concrete wall 3, and that the PC board will not warp convexly toward the outside of the building frame after the building frame is completed. stipulate. The entire inner surface of the PC board 2 is covered with a slip sheet 4 which is an insulating film.
is set up. This slip sheet prevents the concrete parts of the concrete wall 3 and cast-in-place reinforced concrete beam 8 from adhering to the PC board 2, and although it can withstand the compression of the concrete wall to some extent, it directly absorbs the drying shrinkage strain of the wall concrete. It has properties that prevent it from propagating to the PC board.

It is embedded in PC board a and has its tip protruding from the inner surface of the PC board. After construction of the concrete wall 3, it connects the PC board and the wall, and functions as a separator during construction. As shown in FIG. 3, a rubber body 6 is attached to the base of the connecting bolt 5 on the rib 2a side of the PC board, and the connecting bolt is attached to the concrete wall 3.
It is possible to follow the horizontal slide in the relative relationship with the wall.

Beams 8 and slabs 10 are constructed. First, the PC board 2 is installed in a predetermined position, the wall reinforcements 7 and the beam reinforcements 9 are arranged at the same time or after installation, and then the inner wall formwork is assembled using the connecting bolts 5, and this formwork and
After securing the distance from the PC board, set the beam formwork and slab formwork, arrange the slab reinforcement 11, and finally place the space between the PC board 2, wall formwork, beam formwork, and the slab formwork. Pour concrete on the frame, external wall, beam 8
and construct the slab 10. The same process is performed for the upper layer.

Since it functions as a separator during the pouring of wall concrete, it is possible to prevent the PC board 2 from being deformed by the lateral pressure of the concrete. Of course,
It is not necessary for the connecting bolt to have such a function. Furthermore, if the connecting bolts 5 are provided protruding from the ribs 2a, this contributes to making the PC board 2 thinner.

Ribs are horizontally protruded on the inner surface of the PC board, so the PC board will not be affected by temperature changes or drying shrinkage of wall concrete.
This prevents the board from warping, prevents the horizontal tensile stress of the concrete wall from propagating to the PC board, which prevents cracking, and also allows the connecting body to follow the concrete wall by applying an insulating film. As a result, the wall slides smoothly due to earthquakes or temperature changes after construction, and cracks in the PC board can be suppressed.
Therefore, there is no problem with water leakage, the deterioration of the durability of the outer wall can be prevented, and the life of the building frame can be extended.
The aesthetic appearance of the building frame can be maintained over the long term.
