However, in the conventional PC panel having a window frame made of aluminum, since each frame material of the window frame is easily peeled off from concrete, each frame material repeatedly expands in the longitudinal direction due to thermal expansion. However, there has been a drawback that the pressing force is concentrated on the corners of the opening of the PC panel main body and eventually cracks are generated, but no effective countermeasure has been developed for this in the past.

As a means for solving the above-mentioned problems, the present invention provides a PC panel body having a rectangular opening, wherein a frame made of metal upper and lower horizontal frame members and left and right vertical frame members is attached to the inner periphery of the opening. In the PC panel with a metal frame, the length of the frame material extends over the area corresponding to at least each longitudinal end surface of the vertical and horizontal frame materials located at the corner at the opening corner of the PC panel body. A crack preventing structure for a PC panel with a metal frame, in which an elastic cushioning material to absorb the directional extension is filled instead of concrete, is proposed.

FIG. 1 shows an embodiment in which the present invention is applied to a PC panel (1) having an aluminum window frame. The PC panel (1) is provided in a rectangular opening (3) of a PC panel body (2) having a rectangular frame shape. Around
Upper and lower horizontal frame members (4) and (5) and left and right vertical frame members (6),
A window anchor (9) (9) having a length extending over the entire length of a corresponding frame member protruding two by two from each of the frame members (4) to (7) is formed. ), (1)
0), (10), (11), (11), (12), and (12) are mounted by being buried inside the PC panel body (2), and the PC panel (1) with a window frame is driven into concrete. At the time of molding, first, each protruding corner portion of each of the anchors (9), (9) to (12), and (12) of the frame members (4) to (7) is partially cut out, and the frame members (4) to (7) are cut out.
After setting the window frame (8), which forms the framework of (7), at a predetermined position in the concrete formwork, a rectangular mat-like elastic cushioning material (13) made of urethane foam is provided at the anchor notch at each protruding corner. Is bent into a key shape and abutted, and concrete is poured in that state. In this case, the elastic cushioning material (13) has an area covering an area appropriately wider than the longitudinal end surfaces of both the vertical and horizontal frame members at the corners of the window frame.
The PC panel with window frame (1) obtained in this way is
As shown in FIGS. 1 and 2, at the corners of each opening of the PC panel main body (2), elastic cushioning materials (13) form the corners instead of concrete, and form vertical and horizontal frame members. It is in contact with the protruding corner of the window frame (8) so as to cover each longitudinal end face.

In the PC panel (1) with a window frame in which the above-mentioned elastic cushioning materials (13) are installed, the upper and lower horizontal frame members (4) and (5) and the left and right frames at high temperatures such as in summer. The members (6) and (7) are elongated in the longitudinal direction due to thermal expansion, so that, for example, one of the vertical and horizontal frame members at one corner of the window frame is significantly elongated, and the PC panel main body enters the corner in the longitudinal direction. When the part is pressed, or when both the vertical and horizontal frame materials expand significantly, and when the corner of the PC panel body is pressed in the direction of the resultant force of both expansion, the pressing force is elastically damped. It is almost absorbed by the material (13) and suppresses the pressing force applied to the PC panel main body, thereby preventing the occurrence of cracks.

According to the structure for preventing cracks of a PC panel with a metal frame of the present invention, the frame material constituting the metal frame extends in the longitudinal direction due to thermal expansion and presses against the opening corner of the PC panel body. When the pressure is applied, the pressing force is almost absorbed by the elastic cushioning material, so that the occurrence of cracks in the corners inside the PC panel body can be sufficiently prevented.
