[0016] The present utility model can be explained in detail through the following embodiments. The purpose of disclosing the present utility model is to protect all technical improvements within the scope of the present utility model.
[0017] Please refer to Figures 1-4 , this embodiment provides a technical solution: a steel bar welding support arc beam formwork system, including a frame 2, a formwork 1 fixed on the frame 2, and a pipe support 4 supporting the frame 2. The frame 2 is welded by steel bars. The formwork 1 is fixed on the supporting part of the frame 2. The frame 2 is supported and fixed by the pipe support 4. A backing plate 5 is laid at the bottom of the pipe support 4. The formwork 1, the frame 2, and the pipe support 4 are all independent structures, which can be assembled on site without chiseling holes on the ground, are flexible to move, and can be reused.
[0018] The formwork 1 is a multi-layer fair-faced formwork, which has a large format, high strength, elasticity for easy processing and forming, a smooth surface, and easy demoulding, and can speed up the formwork erection speed and form a perfect arc.
[0019] The multi-layer fair-faced formwork is arranged to match the cross-section of the frame 2, which can avoid the trouble of increasing the difficulty of cross-operation when drilling holes for the tie rods.
[0020] The frame 2 is welded by deformed steel bars. According to the size of the arc window, steel bars with diameters of 12 and 14 are used for welding and processing. First, the long arc steel bars obtained by lofting are cold-bent, and then welded and reinforced, and each type of window frame 2 is mass-produced.
[0021] The formwork 1 is fixed above the frame 2 by tying with binding wires. The top support 3 on the pipe support 4 is arranged to support the lower part of the frame 2. The exposed length of the top support 3 for supporting the lower part of the frame 2 is not more than 300 mm to prevent affecting the stability of the top support 3 when pouring concrete.
[0022] The working principle of the arc beam formwork system for steel bar welding support provided by the utility model is as follows: First, the dimensions and radian of all arc windows in the drawings are further refined. The arc radius and arc height are arranged and verified in CAD, and schematic diagrams are drawn for each window support system, such as the length of the arc steel bars, the length and angle of the diagonal supports, etc. According to the size of the arc windows, steel bars with diameters of 12 and 14 are used for welding and processing. First, the long arc steel bars obtained by lofting are cold-bent and then welded and reinforced. The frames 2 of each window are mass-produced. During the processing of the arc molds, while ensuring the stiffness and stability of the frames 2, the accuracy of data such as the arch height and radian of the arc must be ensured; the formwork 1 is a fair-faced formwork with a thickness of not less than 1.2 cm and a specification size of 0.915 m × 1.83 m × 0.012 m. When cutting the formwork 1, the cutting spacing is controlled, and the spacing is not greater than 10 cm, and the cutting depth is 8 - 10 mm. The formwork 1 and the frame 2 are fixed by tying with binding wires. The exposed length of the top support 3 for supporting at the lower part of the frame 2 is not greater than 300 mm to prevent affecting the stability of the top support 3 during concrete pouring. The steel pipes of the pipe rack 4 must be selected from qualified materials with a wall thickness of not less than 3.6 mm. During the splicing process, the thickness of the bottom support cushion plate 5 of the pipe rack 4 is not less than 5 cm. The arc windows adopt a full-length cushion plate 5 to ensure that the bottom is at the same elevation. Through this arc formwork installation method, the integrity of the arc windows is strengthened, the radian of the arc is ensured, the progress is accelerated at the same time, the loss of the arc formwork is reduced, and the rework cost due to formwork bulging and the repair cost of the subsequent arc beam are reduced.
