FORMWORK FOR CASTING CONCRETE}

The present invention relates to a concrete casting space portion (called a cavity in the present application) formed between a formwork panel that is formed by enclosing a rebar set or steel frame and facing each other. The present invention relates to a form for placing concrete, in which concrete is poured to form reinforced concrete structures or steel reinforced concrete structures (concrete structures). Particularly, as a form panel, a first form panel and a second form panel made of foamed synthetic resin are used. It relates to a mold for placing concrete, in which a first mold panel and a second mold panel form a concrete structure integrated with the front and back main surfaces.

BACKGROUND ART Conventionally, a method for forming a concrete building generally includes a reinforcement step of combining reinforcing bars, a mold setting step of placing the reinforcing bars facing the frame panels at a predetermined interval, and a cavity configured between the frame panels. The concrete pouring process which introduces concrete into the inside is performed, and after passing through a predetermined curing period, the mold panel is dismantled to form respective concrete body parts such as posts, beams, walls or slabs. In the conventional construction method, the work of dismantling the assembled form panels and carrying them out of the construction site when forming the concrete body parts is performed in this way, so that the number of days of dismantling work, the form panels and the A space for temporarily storing the member and the like was required.

Moreover, in the formation method of the conventional concrete building, the assembly process of the mounting member for attaching interior materials, such as interior boards, such as a pillar and a shape | mold, is performed with respect to the concrete body part mentioned above. In addition, in the conventional construction method, after installing a heat insulation / moisture-proof body such as a heat insulation / moisture-proof board suitable to the surface of the concrete body to be peeled off, the insulation material, sound insulation, moisture proof, and the like are prepared. The mounting process of is performed. Therefore, in the conventional construction method, heat insulation, moisture proofing, and the installation process are also performed, and the number of days and cost were increasing.

As a method for solving the above-described problem of the conventional method for forming a concrete building, the present applicant also uses a foam panel made of foamed synthetic resin, and a method for forming a concrete structure while leaving the surface of the concrete body portion forming the mold panel. Was proposed (see Patent Document 1). According to the method for forming a concrete building, the dismantling step of the mold panel was not necessary, and the mold panel made of foamed synthetic resin integrated with the surface of the concrete body part was able to obtain the function of the above-described heat insulation and moisture proof body.

[Patent Document 1] Japanese Patent No. 4169159

The mold for casting in concrete described in Patent Document 1 is formed by combining a pair of mold panels made of expanded synthetic resin so that the opposing intervals can be adjusted via a coupling mechanism. The concrete casting mold includes a pair of arms (webs) assembled in an X-shape by connecting a coupling mechanism at a central portion, and a pair of plates formed with coupling pieces connecting the front ends of the arms, respectively, which are combined with the outer surface of the mold panel. It is composed by. In the concrete casting mold, a pair of arms are rotatably coupled in the center portion, and the opposing gap of the mold panel is adjusted by connecting the mounting portion of the plate through which the mold panel penetrates, and the connecting position is adjusted. It is set suitably, and a mold is assembled.

In the mold for casting concrete, a concrete body part having a different thickness can be formed by forming a concrete body part of the mold panel integrated body which can obtain the above-described effect, and by adjusting an opposing gap of the mold panel through a connecting mechanism. Can be formed. In the concrete casting mold, a simple structure connection mechanism also functions as a reinforcing material that retains the mold panel and remains inside the concrete body part and maintains its mechanical strength together with the reinforcing bars. In the concrete casting mold, even if a connecting mechanism is installed in the cavity, sufficient reinforcement space of the reinforcing bar is secured, and the flow of concrete is ensured, so that there are many defective parts, namely, gravel, etc. High-precision concrete body parts without the occurrence of defects).

Although it is a concrete casting mold having various characteristics as described above, after aligning mounting holes formed in each in a narrow cavity formed between the mold panels, each arm and plate are joined by inserting connecting members such as connecting pins. There existed a problem that the workability at the time of assembly deteriorates slightly. In addition, in the mold for pouring concrete, many connecting pins for connecting the arm and the plate are used together with the connecting member for connecting each arm, so that parts are saved in comparison with the conventional method, but the number of parts is still high. There was a problem. In addition, in the mold for pouring concrete, high precision reinforcement was performed by integrally forming the assembling portions of reinforcing bars on each arm, but there was a rather cumbersome place for the assembly.

The present applicant followed the characteristics of the above-described application for placing concrete for forming a concrete panel of a mold panel-integrated concrete building, and intensively studied to solve the problem.

Form.

Concrete casting molds are formed by forming a plurality of base plate assembly parts side by side in the longitudinal direction at the positions where the first mold panel and the second mold panel face each other, and in the thickness direction thereof. It penetrates through and forms a 1st web embedding slit and a 2nd web embedding slit, respectively. In the mold for pouring concrete, the first web and the second web of each web set respectively form a connecting portion at a central portion, and form a first base plate engaging portion at one end side and at the other end a second base plate engaging portion at the other end side. It forms and forms a web set by combining the center part through a connection part, and combining it in an X shape. The first web and the second web have a first base plate engaging portion and a second base plate engaging portion formed at the distal end portion with the web set being combined with the first mold panel and the second mold panel. Or a first web insert slit or a second web insert slit formed to face the second mold panel so as to protrude outwardly from the base plate assembly.

The mold for pouring concrete is formed on the first base plate and the second base plate, and the first base plate engaging portion of the first web or the second web through the first web insertion slit or the second web insertion slit. A first web engagement portion and a second web engagement portion are formed opposite the two base plate engagement portions. The first base plate and the second base plate are provided in the respective base plate assembly parts from the outer surface of the first or second mold panel with the web set combined with the first or second mold panel. Mounted and detached. The first base plate and the second base plate are engaged with the first base plate engaging portion of the first web or the second base plate engaging portion of the second web which protrudes outwardly through the first mold panel and the second mold panel. The portions are respectively engaged with the first web engagement portion or the second web engagement portion facing each other and assembled to the base plate assembly.
