Description

Technical Field

[0001] This utility model relates to the field of construction formwork technology, specifically to an angle-adjustable arc-shaped telescopic formwork. Background Technology

[0002] Curved expansion joint formwork is a type of formwork used in building construction for casting curved structures. It features adjustable curvature and expansion capabilities, adapting to the needs of curved construction of different sizes and shapes. It mainly consists of a panel, a support system, and expansion adjustment devices. Panel: Typically made of materials such as steel plate, wood board, or plastic board, it directly contacts the concrete, forming the surface of the curved structure. Support system: Includes joists, supporting steel pipes, etc., used to support the panel and ensure the stability and strength of the formwork during concrete pouring. Expansion adjustment devices: Such as turnbuckles and threaded adjustment sleeves, these devices allow adjustment of the formwork's curvature and dimensions to adapt to different construction requirements.

[0003] For example, the prior art application number CN202420806417.6 relates to an adjustable angle arc-shaped top formwork, including: a support column, a support beam, an upper flat beam, a lower flat beam, and a top formwork. The upper flat beam and the lower flat beam are located on the upper and lower sides of the support beam, respectively. The upper flat beam, the support beam, and the lower flat beam are arranged in an "I" shape along the length of the beam. The support column supports the lower part of the lower flat beam from bottom to top. The bottom surface of the top formwork is provided with multiple perforated ear plates. The ear plates are pulled and fastened to the upper flat beam and the lower flat beam by tie rods that can extend and retract along the axis, which bends the top formwork into an upwardly convex arc surface.

[0004] The above-mentioned prior art, through actual use, mainly uses a sleeve and a hook (turnbuckle) to adjust the angle of the arc-shaped template. However, it was found through use that due to the construction site environment, dust and concrete debris can easily enter the sleeve and adhere to the outer surface of the hook, resulting in difficulty in rotation and wear that affects normal operation. Therefore, we have improved the above-mentioned prior art based on actual usage. Utility Model Content
