That is, the band-shaped member 6 is applied to the back surface side of the form panel 1 so as to cover the joint portion 5, and the receiving member 4 is applied from outside the band-shaped member 6.
Then, the mounting member 7 is fixed. A hole 6A for inserting the mounting member 7 is formed at a predetermined position of the band-shaped member 6, and a packing material 8 is provided between the joint portion 5 and the band-shaped member 6. It is preferable that this packing material 8 is attached to the back side of the belt-shaped member 6 in advance. When the band-shaped member 6 with the packing material 8 is attached to the form panel 1 so as to cover the joint 5 with the attachment member 7, the sealing material 9 is sandwiched between the joints 5.

The formation of the groove 10 prevents the corners and the periphery of the hollow molded article 2 after blow molding from being rounded. In the blow-molded hollow molded product 2, when the parison in the mold is molded by air blow, the resin at the edge portion is stretched most by blowing pressure, and particularly in the case of a rectangular shape, the corner portion is stretched. It is cooled and solidified in the state. When the foamed material is foamed inside the hollow molded article 2 at the same time as or after the blow molding, 1
Since high-temperature steam of 20 ° C. to 140 ° C. is used, the heat causes secondary shrinkage of the hollow molded article 2 and the hollow molded article 2
The formation of the groove 10 prevents the resin at the edges and corners from being pulled to the center and the corners and the like becoming rounded. Groove 10
Is preferably about 5 to 10 mm. In the embodiment, the receiving member 4 is inserted behind the groove 10.

からのはみ出しは防止される。FIG. 4 shows an example of the belt-shaped member 6, which is formed of a resin material in the shape of a thin plate. By keeping the left and right distance W of the mounting hole 6A constant, the receiving member 4 is formed. If it is buried in a predetermined position, the space between the joint portions 5 can be made constant. Concrete is driven into the space on the side where the band-shaped member 6 is attached. Before the poured concrete hardens, the concrete tends to flow out of the gap of the joint 5 to the front side.
Overflow is prevented.

At times, the receiving member is embedded so as to be wrapped with the blow molding material along each side of the rectangular back surface, and a band-shaped member is applied to cover the joint portion on the concrete driving side of the joint portion where the side surfaces of the form panels are abutted. Since the mounting member is fixed to the receiving member from the outside of the band-shaped member, it is possible to prevent the concrete from protruding from the joint after the concrete is driven. Further, since the resin foam filled in the interior of the form panel is completely covered with the hollow molded product, complete waterproofing is achieved when this resin foam is used as a heat insulating layer. Further, in the case where the packing material is provided between the joint portion and the band-shaped member, generation of slag can be further prevented. Further, in the case where the space between the joints is fixed by pre-positioning the attachment member insertion position of the band-like member, the joints are not misaligned, and are fixed to the concrete wall surface after the concrete is hardened. It is also easy to waterproof the joints of the frame panel. In particular, even when a sealing material is provided in the joint, the effect of the sealing material is improved by keeping the gap between the joints constant.
