The invention patent with application number 202311636074X discloses a high-rise building edge anti-slope formwork support structure and a construction method thereof. The high-rise building edge anti-slope formwork support structure includes steel beams, external formworks, internal formworks, tension bolts, external fixed angle steels, reinforcement rods and embedded parts; the embedded parts are pre-prepared in the floor panel and the floor panel is arranged on the steel beam; the external formwork is perpendicular to the floor panel, the external formwork is arranged along the outer edge of the structural plate edge line and the external formwork is welded and fixed to the steel beam; the inner formwork is arranged on the floor panel and the inner formwork is parallel to the outer formwork, and multiple sets of tension bolts are arranged between the inner formwork and the outer formwork, and an external fixed angle steel is fixed on the outer side of the inner formwork. One end of the reinforcement rod is welded to the external fixed angle steel, and the other end is fixed to the pre-prepared parts. It has good safety and simple operation, and has good application prospects, but the structure occupies a large space, and cannot meet the construction requirements for the situation where one side is cantilevered and the other side is cast in a large area.

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] like Figure 1 , Figure 2 and Figure 3The illustrated device for supporting edge formwork comprises a fixed connector 1 fixedly mounted on a concrete structure, an adjusting rod 2 fixedly mounted on the fixed connector 1, and a locking assembly 3 adjustably mounted on the adjusting rod 2. One end of the adjusting rod 2 passes through the formwork and is located outside the formwork. The locking assembly 3 presses the formwork against the edge of the concrete structure to achieve fixed support for the formwork. During construction, holes with a depth of 50 mm and a diameter matching the fixed connector 1 are drilled at intervals of 1 m on the existing concrete, and then the fixed connector 1 is installed in the hole. The fixed connector 1 is formed by welding and fixing two vertically arranged steel bars, and the fixed connector 1 is cross-shaped or T-shaped. In a preferred embodiment, a sleeve 4 is fixedly arranged on the adjusting rod 2 by welding, and the fixed connector 1 is inserted and installed in the sleeve 4, which is convenient for the connection between the two and improves the installation efficiency, and is also convenient for the separate manufacturing and transportation of the structure and reduces the transportation space.

[0021] In one embodiment, the adjusting rod 2 is a screw rod. The locking assembly 3 includes a first pressing member 30 slidably arranged on the adjusting rod 2 and a first locking nut 31 threadedly arranged on the adjusting rod 2. The operator rotates the first locking nut 31 to press the first pressing member 30 on the template to support the template. During operation, in order to increase the contact area between the first pressing member 30 and the template and make the extrusion support force more uniform, a gasket is arranged between the first pressing member 30 and the template to better transmit the extrusion force.

[0022] like Figure 4 and Figure 5 In another embodiment shown, the locking assembly 3 includes a connecting rod 32 detachably connected to one end of the adjusting rod 2, a second pressing member 33 slidably mounted on the connecting rod 32, and a second locking nut 34 threadedly mounted on the connecting rod 32. The operator rotates the second locking nut 34 to press the second pressing member 33 onto the template to support the template. Specifically, the connecting rod 32 and the adjusting rod 2 are detachably connected via a clamping rod 5 and a clamping groove 6. The clamping rod 5 is fixedly mounted on the end of the connecting rod 32, and the clamping groove 6 is mounted on the end of the adjusting rod 2. The connecting rod 32 and the adjusting rod 2 can be connected and separated by relatively rotating them. The connection position of the connecting rod 32 and the adjusting rod 2 is located in the mounting hole on the template. After disassembly, only a small portion of the adjusting rod 2 needs to be cut, resulting in less material waste.
