Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface plate used for placing precast concrete members such as curtain wall panels, middle and high-rise housing panels, beams, columns, and slab boards.
The present invention relates to a form making method using the surface plate.

[0002]

2. Description of the Related Art Conventionally, for example, a precast concrete panel is placed in a manufacturing plant by the following procedure. Place the form material B on the set face plate A of the surface plate according to the size of the precast concrete panel (Fig. 1
0), a plurality of positioning holes D are drilled at appropriate intervals so that both the mounting piece C extending from the lower end of the mold material B and the set face plate A are commonly penetrated.

The form material B is positioned by driving the insertion pin E into the positioning hole D. Between the pitches of the positioning holes D, common fixing screw holes F are drilled in the mounting piece C and the set face plate A with a drill and a tap. Note that, in FIG. 10, the positioning hole D and the fixing screw hole F are shown on the same cross section for convenience. The bolt G is inserted into the fixing screw hole F and screwed to fix the frame material B. In this way,
Several formwork materials B are assembled on a surface plate to form a target formwork. Next, after arranging the inside of the formwork appropriately, concrete is poured. In the formwork, the surface plate forms the bottom and supports concrete loads.

In such a method of forming a mold, the set face plate A of the surface plate is composed of a thick plate of 9 to 12 mm, and a large number of positioning holes D and fixing screws F must be provided at intervals of 150 to 200 mm. Therefore, the work of forming the positioning hole D and the fixing screw hole F by stacking the set face plate A and the mounting piece C is a great labor. In addition, for example, the dimensional accuracy required for precast concrete panels is high, and it is said that the construction will be hindered unless there is an error of 1 mm at 3500 mm. For this reason, great effort is required to secure dimensional accuracy when performing the above-mentioned drilling process in a precast concrete manufacturing plant.

Further, there are various shapes and sizes of precast concrete products, and it is necessary to provide a large number of positioning holes D and fixing screw holes F each time a product of a different type is placed. Beams are a kind of product,
The cross-sectional dimensions differ for each building level, and the formwork dimensions must be changed each time. In such a situation, not only the work efficiency is poor, but also the set face plate A becomes full of holes, and the surface plate having many irregular holes becomes useless.

[0006] Further, the formwork manufacturing company produces the surface plate and the formwork B according to the design drawing, assembles the formwork B on the set face plate A, and confirms it before delivery. This may not always be reproduced exactly on the shop floor. At present, the layout of the formwork materials and the holes formed in the surface plate at the manufacturing plant depend on the circumstances of the manufacturing company.
