Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mold assembly method for assembling a mold using a plurality of mold panels and a mold panel used for carrying out this method.

[0002]

2. Description of the Related Art Conventionally, when assembling a mold with a plurality of mold panels, a reinforcing frame is integrally provided around the back surface side of a rectangular face plate having several fastening holes at desired positions. First, a plurality of formwork panels having the above-mentioned structure are joined on the base surface formed by pouring out the discarded concrete, and the side faces facing each other are joined in a butt-to-face condition in sequence. Assembling the formwork panel rows by standing up in one row, and then arranging the formwork panel rows in the same manner at predetermined intervals in this formwork panel row, and each formwork of the opposing formwork panel rows. Panels are connected by separators, and the mold is assembled by tightening and fixing while maintaining the above-mentioned predetermined interval.

By the way, the connection between the opposite mold panels by the separator is carried out by using the tightening holes formed in the face plate of one of the mold panels so as to project the separators into the respective tightening holes. At the same time, the other formwork panel facing the formwork panel is handled so as to stand up and the end portions of the separators are fitted into the several fastening holes formed in the face plate, and the fastening rod is attached to the other work piece. After connecting from the outer surface side of the form panel to the tip of the separator, a wedge member is driven into the fastening rod to connect and fix the opposing form panels.

[0004]

However, according to such a mold assembling method, as compared with several separators protruding from several tightening holes formed in the face plate of the mold frame panel on one side, While raising the form panel on the other side, it is necessary to simultaneously fit several fastening holes formed in the face plate to the tips of the opposing separators and fit them together at once. However, if the separator and the tightening hole are misaligned even in one place, the fitting work cannot be performed, and there is a problem that the assembling work is difficult and labor is required, and the work efficiency is significantly reduced.

Further, since the tightening holes are provided in the relatively thin face plate of the form panel, warping may occur in the face plate when the opposite form panel is tightened via the separator. In addition, there is a possibility that the tightening hole portion may be damaged or clogged when pouring concrete, and it may be damaged even when the mold is dismantled, so that it cannot be reused. An object of the present invention is to provide a formwork assembling method capable of completely eliminating such problems and a formwork panel used for carrying out the method.

[0006]

In order to achieve the above object, the method of assembling a formwork of the present invention comprises a plurality of formwork panels provided with several notched recesses on both end faces at regular intervals in the length direction. A step of forming a formwork panel row by arranging the formwork panel rows in a lateral direction while abutting opposite end surfaces of adjacent formwork panels.
A step of arranging this formwork panel row in front and back with a desired interval and a separator in a separator mounting hole formed by notched recesses that match each other when abutting opposite end surfaces of adjacent formwork panels. The step of attaching and connecting and fixing the frame panels facing each other in the front and rear by the separator.

Further, as a formwork panel used for carrying out this method, when a plurality of notched recesses are provided on both end faces at regular intervals in the lengthwise direction, the end faces of the formwork panels facing each other are abutted. It is configured such that the notch recesses that coincide with each other form the separator mounting hole.

[0008]

When the opposite end faces of the adjacent form panels are sequentially abutted to each other to form a single form panel row, the notched recesses formed on the side faces of the adjacent form panels are aligned with each other to attach the separator. A hole is formed. Then, such form panel rows are assembled in parallel at a desired interval, and both ends of the separator are inserted between the separator mounting holes facing each other, and are locked so that the separator is removed from the outer surface of the form panel. The mold frame is assembled by tightening and fixing the mold frame panel rows with a certain interval.
