ある。(Prior Art) Recently, there are examples in which outer walls are constructed of PC boards and cast-in-place concrete, and one example of this is the one disclosed in Japanese Patent Publication No. 5431293. In this example, the outer wall is constructed by using a thin PC board, positioning the PC board on the surface side of the outer wall, and pouring cast-in-place concrete inside the PC board. The PC board and the inner concrete are connected by an inverted V-shaped fixing reinforcing bar that protrudes from the inner surface of the PC board.

The anchored reinforcing bars that protrude from the inner surface of the C plate become obstacles, making installation time-consuming and difficult to transport, and the main reinforcing bars of columns and beams arranged on site interfere with the main reinforcing bars that protrude. Therefore, there is a problem that the cost increases unnecessarily, such as having to increase the thickness of the cast-in-place concrete portion.

ている。As shown in FIGS. 2, 5, and 6, the joining recesses 4 have an elongated rectangular longitudinal cross-sectional shape, a square front shape, and are spaced at equal intervals along the entire outer circumference of the inner surface of the PC board. The inner surface of the PC board 2 has a sufficient internal shape to function as a bond between the PC board and the concrete 3.

めの手段として機能する。The joining recess 4 is formed on the PC board 2 by pouring concrete into the forming form and curing the lower surface of the thin rectangular form board before the concrete hardens during the manufacture of the PC board. Embed approximately half the thickness of the formwork board downward from the top of the concrete. Therefore, on the outer periphery of the PC board 2, a group of bonding recesses 4 consisting of continuous bonding recesses 4 are formed at intervals. The joint recess 4 is formed during exterior wall construction, which will be described later.
It functions as a means for mutually joining the PC board 2 and cast-in-place concrete 3.

、まずＰＣ板を施工する外壁の表面側の位置に建込む。To explain how to construct the outer wall 1 using the PC board 2,
When manufacturing a PC board for an external wall, a PC board is manufactured in which a plurality of joining recesses 4 are formed at intervals on the outer periphery of the inner surface of the PC board, and the PC board is first installed at a position on the surface side of the external wall where the PC board is to be constructed.

法を提供できる。At this time, the PC board is kept with the surface where the joining recess 4 is located facing inward. Next, when a predetermined thickness of cast concrete 3 is placed on the inner surface of the PC board 2, the PC board and the concrete are integrated into one piece due to the function of the joint recess 4, as shown in a partially enlarged view in FIG. is combined with As a result, the PC board is not only used as formwork or finishing face plate during construction, but also works together with the concrete to create an integrated wall structure that can absorb horizontal forces (mainly earthquake forces).
The PC board itself can be designed as a structure, and a construction method can be provided that allows the thickness of concrete to be poured to be made thinner.

This eliminates the problem of obstacles and difficulty in transporting. Since the joining means is in the form of a recessed joint, installation of the joining means and PCC reinforcing work are facilitated. In addition, by constructing the exterior wall using PC boards with joint recesses, the PC board is strongly integrated with the concrete poured in place, so the PC board can be designed as a structure in addition to functioning as formwork or finishing face plate. , the thickness of cast-in-place concrete can be reduced.
