The present invention relates to a formwork supporting waler, in particular in the rod fitting hole of one side of the supporting waler having a predetermined length along the circumference of the formwork in the direction perpendicular to the fitting portion of the rod body which is the other side of the supporting wail It is to be coupled and supported in a wrapped form.

In general, as a method for constructing a concrete wall or column, reinforcing bars are arranged at the upper part of the foundation floor or slabs, and formwork is installed at the edge of the reinforcing bars in accordance with the design dimensions.

At this time, the formwork to be used is such that the other fastening holes formed on both sides of the other form the contact with the fastening holes formed on both sides of the formwork, and then the fastening pins formed with pin grooves through the fastening holes are coupled, through each of the fastening holes The other fastening pin having the same shape as the fastening pin is installed to be inserted and coupled to the pin groove of the exposed fastening pin by hitting. The process is repeated to build concrete walls or columns.

However, there is a problem in that a gap is generated between the formwork and the formwork coupled to the fastening pins due to the strong pressure acting on the lower part of the formwork, especially when placing concrete in the process of wall or pillar construction using such formwork.

On the other hand, as a way to solve this problem, as shown in Figures 1 and 2, a form fixing clamp 500 is proposed, such a clamp 500 is provided on both sides of each form 600 to face each other.

It is configured to prevent the thread of wear.

In addition, the process of pouring the fastening nut 540 is coupled to both ends of the bolt 530 exposed through the bolt insertion groove 511 formed in the bolt protector 520 and each support piece 510, respectively. In order to prevent the floating between the formwork 600 and the formwork 600 due to the pressure acting from the inside of the formwork (600).

However, the clamp 500 having such a structure can be easily used for the formwork of concrete walls or pillars having a narrow gap between the formwork 600, respectively, and to the formwork having a wide spacing for constructing concrete pillars or walls with relatively large spacing. There was a difficult problem to use. That is, in the case of the formwork for concrete wall construction, only the two sides simply need to be fixed, but in the case of the formwork for the construction of concrete pillars, the bolt protector 520 to both sides of the bolt 530 in the process of fixing all sides including both sides ) And the bolt insertion groove 511 formed in the support piece 510 to be exposed, and the tightening nut 540 is coupled to both sides of the bolt 530 exposed by the bolt insertion groove 511, respectively. By repeating a lot, there was a problem that the work time is delayed by that much increase in construction period and cost, there was another problem that the cost of manufacturing a large amount of form fixing clamp increases.

In addition, when the clamp 500 is installed on the formwork 600 of the concrete pillar from the side, it is not installed in a straight line in parallel but has a zigzag form, which is not only dizzy in appearance but also causes the worker to form a space between the formwork. There was another problem of being injured while falling over the clamp 500 or torn clothes in the process of moving.
