Self-adaptive connecting device for tower crane to be attached to wall and construction method of self-adaptive connecting device

Abstract

The invention relates to a tower crane wall-attached self-adaptive connecting device and a construction method thereof, and the tower crane wall-attached self-adaptive connecting device comprises four tower crane connectors which are respectively connected to four support angle steels of a tower crane standard knot; the connector locking mechanism comprises interlocking convex edges which are correspondingly and fixedly connected to the inner sides of the extending parts of the inner side steel plates and the outer side steel plates of the tower crane connectors, and the outer sides of the extending parts of the inner side steel plates and the outer side steel plates of the tower crane connectors are locked through locking bolts respectively; the inclined supporting mechanism comprises four inclined supporting rods which are obliquely connected between the tower crane connector and the floor slab; and the connecting and supporting mechanism comprises connecting structural parts arranged in the middles of the four tower crane connectors, the positions, corresponding to supporting steel plates of the tower crane connectors, of the connecting structural parts are each provided with an abutting part in a telescopic mode, and the abutting parts are connected to the corresponding supporting steel plates in an abutting mode. The lateral rigidity of the tower crane can be effectively improved, and the standard knot of the tower crane can be prevented from buckling damage.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a self-adaptive connecting device for a tower crane attachment wall and a construction method thereof. Background technique [0002] With the diversification of our architectural forms, public building projects such as special-shaped buildings, large stadiums or exhibitions are becoming more and more common, making it difficult to attach tower cranes to walls. Considering the construction hoisting, building height and construction deployment reasons, the conventional attachment wall of the tower crane can no longer meet the construction requirements. However, the tower crane is a towering cantilever structure with poor stability. When the tower crane is in strong wind and typhoon weather, the tower crane is prone to instability and collapse, resulting in huge economic losses and personal safety. According to statistics, when Typhoon Moranti passed through Xiamen in...

Problems solved by technology

In this way, although the standard section of the tower crane has been improved to a certain extent, that is, the lateral stiffness of the tower body has been improved, but the welding points on the standard section or the setting of screw holes will inevitably reduce the original supporting effect of the standard section. In turn, the local structural stability of the tower crane standard section is damaged. Therefore, when strong winds and typhoons pass by, the parts where the tower crane standard section is equipped with connecting components still have local stress concentration and hidden dangers of buckling failure.
