The present invention relates to a timber bracket for fixing the formwork crossbar, and more particularly, to a timber bracket capable of fixing not only a circular pipe but also a two-stage stacked state thereof, and an improved tightening force thereof.

In general, in order to pour concrete at the time of construction of a building, formwork is formed with a number of panels formed to a certain standard, and concrete is placed inside the structure so that the building is built in the form of formwork. The formwork to be addressed is fixed by combining a number of squares on the outer surface of the formwork in order to prevent the formwork from being pushed out because high internal pressure is generated in the formwork by the weight of the concrete when the concrete is poured.

As mentioned above, in order to prevent the formwork from being pushed out by the pressure of the concrete, a square pipe fixture for fixing a formwork for fixing a square pipe (power steel, square steel pipe, etc.) to the formwork has been variously proposed in the related art.

 Conventionally, the square fasteners for fixing the formwork are known as the square pipe fasteners of the Republic of Korea Utility Model No. 0215943, which are bent to the rear side of the supporting portion having a coupling portion coupled to the formwork to be inclined in one direction, and have a long hole in the support. Combining the sphere and hitting the crimp in the lateral direction, the crimp is moved in the lateral direction by the support hole formed inclined to move forward to fix the timber, but when the formwork and the timber are pressed by placing concrete, Although the pressure must be supported by the support, the support was bent backwards by the pressure, so there was a drawback that the support was not sufficiently supported.

In addition, the wood used in the cross-sectional standard is a standard product such as 80 * 80, or 50 * 50 is used, and the pins used in the coupling portion of the fixture and the formwork is also used in the form using pins and round pins. Therefore, in the construction site, each wooden fixture should be provided according to the specifications of the used wood, and each wooden fixture must be equipped with a wooden fixture that can fix the wooden according to the above standards, and the wooden fixture must be selected according to the shape of the pin used in the combination of the fixture and the formwork. There was a flaw. This conventional fixing structure has a drawback of taking a lot of time and power to fix or release the wooden box because the work to tighten the wooden box to fasten the bolt.
