Description

Technical Field

[0001] This utility model relates to the field of bolt positioning frame technology, and in particular to a plate-type variable cross-section tower crane foundation anchor bolt positioning frame. Background Technology

[0002] Considering overall cost and installation, most small and medium-sized tower cranes use bolt-fixed foundations. When constructing bolt-fixed foundations, anchor bolt positioning frames are needed to position the anchor bolts and prevent deviations that could prevent installation. The main function of the anchor bolt positioning frame is to ensure the accurate position and verticality of the anchor bolts during concrete pouring, thereby guaranteeing the precision and stability of the equipment installation. Through its design structure and installation method, the anchor bolt positioning frame ensures the accurate positioning of the anchor bolts in the concrete, avoiding instability or tilting caused by positional deviations. The working principle of the anchor bolt positioning frame relies primarily on its structural design. The positioning frame typically consists of one or more positioning rings fixed to the formwork. The anchor bolts pass through the positioning rings and are fixed to the formwork. During concrete pouring, the positioning frame ensures the anchor bolts remain in the correct position and angle, preventing movement or tilting. After the concrete solidifies, the anchor bolts form a strong connection with the concrete, ensuring the stability and safety of the equipment.

[0003] However, traditional tower crane foundation anchor bolt positioning frames cannot meet people's needs due to the following drawbacks: First, they lack a variable cross-section structure. Most current positioning frames are either integral or made on-site using steel bars. Integral positioning frames are bulky and cannot achieve variable cross-sections or multi-purpose functionality. They require a separate frame for each foundation section, making transportation difficult and necessitating the use of small trucks. This significantly increases the manufacturing and transportation costs of the device and fails to effectively achieve the positioning effect, thus failing to ensure the stability and safety of the equipment. Second, they lack a standardized size structure. Existing simple positioning frames lack standardization, and dimensional deviations depend on the operator's skill level, easily leading to significant errors. This reduces the economic efficiency and effectiveness of the device, failing to effectively improve the practicality and cost-effectiveness of the positioning frame application.
