Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a prefabricated base of a steel structure well. Background Art

[0002] The steel hook shaft is composed of multiple square tubes, and at its bottom, it contains a prefabricated concrete base. The traditional connection between the base and the square tube is assembled by bolts. In detail: a square steel plate is welded to the outer wall of the bottom of the square tube, and the steel plate contains holes. The expansion bolts pass through the holes and are driven into the prefabricated base to complete the installation.

[0003] In the process of implementing this solution, the inventors found that the following problems existed in the prior art and have not been well solved: although it can achieve a fixing effect, the fixation between the two is completely completed by the combination of expansion bolts and square steels. The elevator will produce a certain degree of shaking during the lifting process, and part of the force will be transmitted to the steel plate and expansion bolts through the square tube. However, due to the single fixing method and limited fixing effect, it is easy to cause cracks between the steel plate and the square tube after metal fatigue, and safety and stability cannot be effectively guaranteed.
