Connecting device for construction elevator to be attached to tower crane

Abstract

The invention discloses a connecting device for a construction elevator to be attached to a tower crane. A square steel clamp (1) is connected with tower crane standard knots (14) through M20 high-strength bolts (2). The tower crane standard knots (14) are connected with elevator standard knots (15) through adhering bars (10) located on the inner sides and outer sides of the upper layer and lower layer correspondingly. The square steel clamp (1) is connected with upper-lower layer clamp connection lifting lug pulling plates (5). The upper-lower layer clamp connection lifting lug pulling plates (5) are connected with the elevator standard knots (15) through adhering bars (10) on the outer sides, M15 high-strength bolts (13) and a positioning frame (11). The square steel clamp (1) is connected with upper-lower layer clamp connection lifting lug bottom plates (7). The upper-lower layer clamp connection lifting lug bottom plates (7) are connected with the elevator standard knots (15) through adhering bars (10) on the inner sides and movable fasteners (12). An elevator cage (16) is reversely buckled to rails of the elevator standard knots (15).

Description

technical field [0001] The invention relates to a connection device for a construction elevator attached to a tower crane. Background technique [0002] In the construction of high bridge piers, the traditional elevator design is generally designed independently of the tower crane standard section. The elevator is generally designed to reach the bottom of the box girder and a hole is opened at the bottom of the box girder, and stairs are built to the bridge deck through the inner box of the box girder. The traditional elevator design scheme affects the stiffness of the box girder in the construction stage, which is not conducive to the safety of the bridge construction stage. In order to solve the problem that the bridge box girder is wide and does not allow construction of the elevator entrance on the box girder floor, a special design A connection device for construction elevator attachment and tower crane is proposed. Contents of the invention [0003] The technical pr...
