Tower crane wall-attached frame for construction of extra-large bridge main pier

Abstract

The invention discloses a tower crane wall-attached frame for construction of an extra-large bridge main pier, and particularly relates to the field of tower cranes. The tower crane wall-attached frame comprises an embedded part mechanism for casting, the top and the bottom of the embedded part mechanism for casting are both fixedly provided with a middle shaft fixing mechanism, and one side of the embedded part mechanism for casting is welded with a wall-attached frame fixing mechanism; and the embedded part mechanism for casting comprises a cylindrical embedded part, a first built-in movablegroove is formed in the center of the cylindrical embedded part, and a plurality of peripheral disc-shaped embedded parts are fixedly installed on the outer wall of the cylindrical embedded part. Through the arrangement of the embedded part mechanism for casting, embedded rods for side supporting and the peripheral disc-shaped embedded parts can be embedded in a concrete layer of a floor along with the cylindrical embedded part, and the embedded rods for side supporting and the peripheral disc-shaped embedded parts achieve the secondary supporting and fixing effects on the cylindrical embedded part at the same time; and on one hand, the safety of cast-in-place embedding is improved, and on the other hand, the supporting stability of the cylindrical embedded part is improved.

Description

technical field [0001] The invention relates to the technical field of tower cranes, in particular to a wall frame attached to a tower crane used for the construction of the main pier of a super-large bridge. Background technique [0002] When the tower crane attached to the wall is installed, when the horizontal arm of the tower crane exceeds the free height, tie rods will be set up at intervals to connect the tower crane with the structure, in order to make the tower crane vertically firm and prevent the force generated by lifting objects because it is too high. The tower body shakes or collapses. When the simple ladder on the ground exceeds a certain height, tie rods will be installed at intervals to connect with the structure in order to achieve vertical firmness and prevent instability due to too high a height. The function of the tower hanging tip is to withstand The upper load transmitted by the jib stay rope and the balance jib stay rope is directly transmitted to th...

Problems solved by technology

[0003] When installing the support connector at the bottom of the tower crane, it will be attached to the building body to install the wall bracket due to its high height. The wall bracket is generally installed on both sides of the column of the building and fixed by using a triangular horizontal support method. In some areas, it is easy to have a column on both sides. At this time, it is necessary to insert steel bars and other fixing parts to fix the wall frame on one side of the floor. However, the load-bearing strength of the edge of the floor is much smaller than the load-bearing strength of the column. Easy to install and bear the load of the tower crane
