Description

Formwork for civil works {A cast for foundation work}

The present invention relates to a formwork for civil engineering works, in particular to facilitate the installation and dismantling of the formwork supporting both sides when constructing a wall having a predetermined thickness.

In general, civil engineering works, in particular, when the foundation works, radially couple the reinforcement therein and then form the formwork at a predetermined interval on both sides so that the reinforcement can be accommodated inside the concrete and the concrete inside the formwork Mortar is added and the mold is removed when curing of mortar is completed.

Such formwork is to be installed at the time of civil engineering works, and as shown in FIG. 1, a pillar 3 having a constant thickness in order to prevent deformation of the board 2 on a circumferential surface of the board 2 having a constant size. ) Is attached.

However, such a conventional formwork (1) is mostly made of wood, so even a small impact was broken and there is a problem that the service life is shortened due to moisture.

In addition, in order to keep the formwork on the outside of the reinforcing bar in the state in which the concrete mortar (4) is inserted, holes for joining the spacing bolts (5) are formed in the board (2) to further shorten the service life There was a problem.

In order to solve this problem, a formwork formed of metal may be used, but the metal formwork has a problem of being difficult to handle due to its high weight.

The present invention has been invented to solve the above problems, an object of the present invention is to provide a metal panel bent so that the irregularities are repeatedly formed, the lower portion of the panel is provided with a fixing portion for fixing the panel, the side of the panel By fixing a plurality of rods to support the panel to provide a formwork for civil engineering works for the quick and easy installation and removal of formwork.

The present invention for achieving the above object is characterized in that the concave-convex portion is formed repeatedly bent and formed with a groove portion into which the support rod can be inserted into the recess, and comprises a plurality of support rods are fixed to the groove portion of the panel .

The present invention as described above can lighten the weight of the formwork to be installed for civil engineering foundations to easily perform the installation and demolition work of the formwork, as well as to protect nature by not using wood, to form a groove in the panel and support rods By inserting and fixing the effect that can firmly support the side of the panel.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is an exploded perspective view showing the formwork according to the present invention, the panel 10 is bent to repeat the recess 11 and the convex portion 12 to be fixed to the insertion groove 16, the panel 10 A plurality of grooves 13 are formed at the upper and lower ends of the recesses 11, and the support rods 14 are coupled to the grooves 13 through the screws 17.

Figure 3 shows another embodiment of the panel coupling means of the present invention, forming a plurality of grooves 13 on the upper and lower ends of the main portion 11 of the panel 10, the support rod 14 through the thumbscrew 18 It is configured to be tightened and fixed to be inserted into the groove 13 of the panel 10.

Hereinafter, the operation of the present invention will be described.

In the case of civil engineering work with formwork, the reinforcing bar is radially installed at the central part for forming the wall surface, and the fixing member 15 is fixed to the ground so that the wall surface for accommodating the reinforcing bar is formed. The insertion groove 16 formed in the) is fixed to face upward.

In addition, the lower portion of the panel 10 is vertically inserted into the insertion groove 16 to be fixed. When the extension portion of the panel 10 intersects the recess 11 and the convex portion 12, the panel 10 ) Can be connected continuously.

In addition, concrete mortar is injected into the space formed by the pair of panels 10 to form the wall surface having a predetermined thickness by the panel 10.

And when the curing of the concrete mortar is completed, by removing the interval maintaining bolt and removing the panel 10 attached to both sides of the concrete mortar, the demolition work of the formwork is completed, the main portion 11 of the panel 10 And an inclined surface that forms a predetermined inclination angle between the convex portion 12 and the panel 10 is easily separated.

In the present invention, a plurality of grooves 13 are formed above and below the recessed part 11 of the panel 10, and the support rods 14 are inserted into the grooves 13 and then fixed through the screws 17. 14) the side of the panel 10 is firmly supported.

Here, each of the groove 13 and the support rod 14 is formed with a hole to allow the screw 17 to be fastened.

Meanwhile, as shown in FIG. 4, the present invention forms a hole in the support rod 14, inserts a screw 17 into the hole, and then butterfly the butterfly screw 18 in the screw 17. Since the screw 18 is rotated so that the thumbscrew 18 presses the support rod 14, the support rod 14 is firmly fixed to the panel 10, thereby enabling side support of the panel 10.

1 is a perspective view showing a state of constructing a civil engineering construction with a conventional formwork.

Figure 2 is an exploded perspective view showing the formwork according to the present invention.
