Description

Technical Field

[0001] The utility model relates to the technical field of municipal construction, and in particular provides a force transmission connection structure of a steel perimeter purlin and a steel support. Background Art

[0002] In the process of supporting the foundation pit of municipal construction, the soil pressure is transmitted to the steel support through the steel purlin. The steel support and the steel purlin are both extremely important components in the foundation pit support system. The effective force transmission of the steel support and the steel purlin has become an important link in ensuring the safety of the foundation pit. To support the foundation pit, the two ends of the steel support are generally placed on the steel purlin. The steel support and the steel purlin are connected by prestressing and tightening. A connecting steel plate needs to be set on the steel purlin at the connection. Usually, the steel plate is welded to the steel purlin. When the steel purlin is recycled, the original steel plate needs to be removed and re-welded. Such multiple welding and removal will seriously damage the quality of the steel purlin, reduce the number of times the steel purlin is recycled, and this traditional connection method is complicated to construct, which increases the construction difficulty and construction period.
