Anti-slipping anchor for foundation of split mounting type tower crane

Abstract

The invention discloses an anti-slipping anchor for a foundation of a split mounting type tower crane, which comprises an anchor ring and a clamp plate in the anchor ring. Threads are arranged on the periphery of a clamping end of the anchor ring, matching threads are arranged on an inner peripheral surface of a clamping cap, the clamping cap is connected to the clamping end of the anchor ring in a threaded manner, and a connecting object piercing hole is arranged at the top of the clamping cap. The anti-slipping anchor has a good anti-slipping effect, furthermore, the structure of an existing anchor does not need to be changed, only the threads are arranged on the periphery of the clamping end of the anchor ring, the clamping cap is connected to the clamping end of the anchor ring to tightly jack the clamp plate, and accordingly the anti-slipping anchor is simple in manufacture and low in cost. A sealing ring is arranged on the inner periphery of the connecting object piercing hole at the top of the clamping cap, rainwater can be effectively prevented from entering the connecting object piercing hole, and a corrosion prevention effect is good.

Description

technical field [0001] The invention relates to a foundation for installing and fixing construction machinery, in particular to a connecting piece for an assembled tower crane foundation. Background technique [0002] Concrete prefabricated tower crane foundation, because of its short on-site construction period, convenient and quick disassembly, assembly and transportation, no environmental pollution, no waste of resources, and can improve the utilization efficiency of tower cranes and save the use cost of tower cranes, is generally welcomed , get a better promotion and application. In recent years, the applicant has filed a series of patent applications and obtained authorization to further improve and improve the foundation of the concrete prefabricated and assembled tower crane. The anti-slip fastening device" is a further improvement on the fastening device for connecting the steel strands of each prefabricated part. The fastening device (anchor plate clamp) in the pri...

AI Technical Summary

Problems solved by technology

It can be seen from the above that this kind of "anti-slip fastening device" has the following defects: first, the processing and production are relatively complicated (a special mold is required, and tapping on the inner peripheral surface is required); second, it has high requirements for the use environment, such as Do not soak in water or soil for a long time, otherwise it is easy to rust and pose a threat to the safe use of the tower crane
