FIG. 1 shows an embodiment of the present invention. 1 in the figure is P
A gantry frame having a contact surface portion 1a of the same shape corresponding to the end surface 10a of the C plate 10 to be attached to the end surface 10a in contact therewith, and 2 is attached to the side surface portion of the gantry frame 1 (screw bolt or the like) 3 to contact surface A connecting flat bar that projects to the side and bolt-connects (inserts, bolts, etc.) 6 to the side surface of the PC plate 10, 10 is a PC plate such as a PC curtain wall with a bay window 11, 10a is an end face of the PC plate 10, and In the embodiment, a wooden frame 1 having a contact surface portion 1a of the same shape corresponding to the end surface 10a of the PC plate 10 such as a PC curtain wall and attached to the end surface 10a in contact with the end surface 10a, and a side portion of the frame 1 are provided. This is a PC plate curing frame equipped with a connecting flat bar 2 which is mounted 3 and protrudes to the contact surface side to connect the bolts 6 to the side surface of the PC plate 10.

A PC plate 1 such as a PC curtain wall
After placing 0 and releasing the mold, on the end surface 10a of the PC plate 10,
A wooden gantry frame 1 having a contact surface portion 1a of the same shape corresponding to the end surface 10a is placed in contact with the pedestal frame 1 and mounted on a side portion of the gantry frame 1 to project a connecting flat bar 2 protruding toward the contact surface side. This is a PC plate curing method in which bolts 6 are connected to the side surface of the PC plate 10 and the gantry frame 1 is attached to the end surface 10a of the PC plate 10 for protection and handling.

More specifically, the gantry frame 1 is preferably made of wood and is formed by impregnating or applying a synthetic resin, or by adhering a synthetic resin, an iron plate, or the like, if necessary, and is relatively lightweight and suitable. It is formed of a member having strength and elasticity, and its upper surface side is formed on the contact surface portion 1a of the same shape formed corresponding to the end surface 10a of the PC plate 10 to be attached as shown in the drawing, and corresponds to the end surface 10a. The structure is formed to have a length to protect the end face 10a and the corner portion thereof. Further, the flat bar 2 is preferably made of iron and formed of a synthetic resin material or the like if necessary, and bolt holes are provided in the upper and lower portions, and the flat bar 2 is detachably attached to the side surface of the gantry frame 1 by the screw bolts 3 or the like. Then, a plurality of them are attached 3 at intervals in the length direction of the gantry frame 1 so as to project to the contact surface portion 1a side, that is, upward in the figure.
The end frame 10a has a structure in which the mount frame 1 is attached to the end surface 10a of the PC plate 10 by detachably connecting the frame 5 to the end surface 10a of the PC plate 10 by means of the insert 5 and the bolt 6 which are provided so as to project.

For example, a PC curtain wall (PC plate) 10 with a bay window 11 as shown in the figure is first cast in a factory or the like and released from the mold, and then the contact surface portion 1a of the frame 1 is attached to the lower end surface 10a thereof. The upper portion of each flat bar 2 mounted 3 on the gantry frame 1 so as to be in contact with each other is detachably bolted 6 by an insert 5 and a bolt 6 projecting from its side surface, and the gantry frame 1 is attached to its end face 10a. Easy to attach and protect, this P
The C curtain wall 10 is easily and efficiently handled for transportation, erecting, and the like, and when the C curtain wall 10 is installed in a predetermined position of the building frame, the frame 1 is removed together with the flat bar 2 by the bolt 6 and installed.

As described above, the gantry frame 1 of the present invention is easily attached to the end surface 10a of the PC plate 10 with the contact surface portion 1a in contact with the end surface 10a. The PC plate 10 can be easily and efficiently handled (transported, built up, etc.), and the end face 10a of the PC plate 10 and the corners can be effectively damaged. Therefore, the workability of the PC plate 10 and the construction accuracy are effectively improved.

In the illustrated example, the flat bar for connection is attached to only one side surface of the gantry frame.
Depending on the type of plate, etc., a flat bar for connection is also attached to the other side of the gantry frame so that the gantry frame is bolted to both sides of the PC plate, or on the other side of the gantry frame. It is also possible to adopt a structure in which a plate for preventing the frame of the frame from coming into contact with the other side surface of the PC plate is provided in a protruding manner. Also,
In the embodiment, the gantry frame is attached to the lower surface of the lower side of the PC curtain wall, but it is attached to the side surface and the upper end surface of the PC frame if necessary.
It is attached so as to protect the end faces and corners of the C plate.

[0013]

According to the present invention, the contact surface portion of the same shape of the wooden frame is placed in contact with the end surface of the PC plate, which is constructed as described above, and is placed and released. By connecting bolts to the side surface of the PC plate through the connecting flat bar, a wooden frame can be easily attached to the end surface of the PC plate easily and easily. The wooden frame is relatively lightweight and suitable. With its strength and elasticity, the PC plate can be easily transported and erected, and can be handled efficiently and smoothly.
The shape of the end faces and corners of the PC plate is effectively prevented from collapsing, and the workability as well as the construction accuracy are significantly improved.
