Description

Form to form a straight jaw {Concrete mold that establish waterproof rise}

The present invention relates to a formwork for forming a flat watertight jaw, in particular, when forming the formwork to form a watertight jaw that is excellent in waterproofing because it is not formed in the surface of the floor concrete, very easy to separate from the floor concrete It's about formwork.

Recently, when constructing a building with reinforced concrete, a waterproof jaw (D) is formed to protrude to a certain height so that water does not penetrate from a wet place, for example, a toilet or a veranda, so as to form the waterproof jaw. Watertight jaw formwork is used.

The waterproof jaw is poured together with the bottom concrete (A) that is poured to form the floor, wherein the waterproof jaw has a protruding shape much higher than the floor concrete, mainly using a rectangular steel pipe, usually Figure 1 Formwork 1 for forming the waterproof jaw as shown in is used.

The concrete formwork for the conventional waterproof jaw (1) is two rectangular pipes 10 spaced apart at regular intervals, the iron plate 11 welded to both end surfaces of the rectangular pipe, the coupling table welded to both sides of the rectangular pipe top (12), a support rod 13 having a conical shape projecting downward in the bottom surface of both ends of the coupling table 12, and the support rod is fitted to be coupled to support the formwork 14.

However, the conventional concrete mold for waterproof jaw (1) as described above should be removed after placing the concrete, the support rod 13 and the base 14 is hard to lift the formwork because it is hardened in the state embedded in the floor concrete After the support rod 13 is removed, a hole (C) is formed in the upper portion of the bottom concrete at the place where the support rod is removed, thereby causing a leakage phenomenon. Therefore, the work for filling the hole must be repeated to prevent the operation. Not only is it cumbersome, it is difficult to have a perfect sealing work, so it has a closed end that leads to insolvent construction.

In addition, the concrete formwork (1) for the waterproof jaw is a square pipe (10) is completely perpendicular to the slab surface (B), so when you want to separate the formwork after the floor concrete is placed, it is not easy to fall out because of cement buried on the surface of the square pipe. Therefore, in order to remove it, it is necessary to exert a force on the formwork, as well as the damage of the formwork as well as having a closed end.

As such, the present invention was devised to solve the drawbacks of the formwork for forming a waterproof jaw, and is arranged to face a square pipe to be welded to an iron plate, but the upper portion of the square pipe is formed by inclined surfaces so that the bottom is opened. It is to provide a formwork to form a straight waterproof jaw to facilitate the detachment of formwork when separating the formwork from concrete.

In addition, the present invention exposes the upper part of the support from the bottom concrete, but the upper part of the support rod is inserted into the bottom of the coupling formed on the top of the form, that is, the cylindrical body so that any part of the form is not buried in the floor concrete so It is to provide a form for forming a straight waterproof jaw to facilitate the separation of the form after curing.

Referring to the configuration of the subject innovation in detail as follows.

The structure of the present invention form 100 is two rectangular pipes 110 spaced at a predetermined interval, the iron plate 120 welded to both end surfaces of the rectangular pipe, the coupling table 130 welded to both sides of the rectangular pipe top In the formwork for forming the waterproof jaw consisting of a support base 140 protruding downward in the bottom surface of both ends of the coupler, and the support is fitted to support the formwork, the rectangular pipe 110 ) To be disposed facing the steel plate 120, but the inclined surface 160 is formed such that the square pipe 110 is closer to the upper end and the lower end is farther away, so that the lower part of the square pipe 110 is opened.

The cylindrical body 131 is welded to both bottoms of the coupling table 130 welded to both sides of the upper end of the square pipe, but the lower part is open so that the support 140 is detachably inserted. In this case, the coupling table 130 may use square pipes and bent flat irons, but it is preferable to use simple flat iron bars that are inexpensive and reduce weight.

The support 140 is made of a thin metal plate, in particular an aluminum plate, and may be bent in various forms, but semi-circular in order to solidify the support of the formwork, and to facilitate the removal of the support rod protruding onto the concrete after the bottom concrete is poured. Bending is preferred.

At this time, the removal of the support rod can be easily broken simply by hitting the projecting portion over the concrete with a hammer (E) as shown in FIG.

Pedestal 150 for supporting the support 140 from the slab surface (B) is provided with a semi-circular fitting groove so that the lower end of the support 140 can be fitted.

In this way, the present invention is arranged to face the square pipe, but by forming the inclined surface to open the bottom to facilitate the detachment of the formwork when separating the formwork from the floor concrete to prevent the damage of the formwork, and to facilitate the work You can do it.

In addition, the present invention exposes the upper part of the support to the upper surface of the floor concrete, so that any form of the formwork can be formed so as not to be buried in the floor concrete, thereby making it very easy to separate the formwork after curing the floor concrete, In addition, since no perforation is formed on the surface of the floor concrete, it is not necessary to perform reprocessing work such as through-hole waterproofing treatment, and thus, it is a very useful design that can prevent insolvent construction and significantly reduce the amount of work and working period.
