Description

Integral lifting sling for long vertical steel bars

technical field

The invention relates to the technical field of a vertical steel bar hanger structure, in particular to an integral hoisting hanger for a long vertical steel bar.

Background technique

With the development of modern bridge construction, the span and bearing capacity of bridges continue to increase, the size of substructures such as pier columns and tower columns is getting larger and larger, and the scale and weight of steel skeletons are also significantly increasing. At the same time, some complex concrete components have clear requirements for the location of steel bar joints, resulting in the frequent use of large-diameter (28-32mm) and super-long (up to 12m when unprocessed and cut off) steel bars, making the installation of steel bars more difficult and inefficient. There are roughly two traditional steel bar installation and construction technical solutions: one method is to tie the semi-finished steel bars and hoist them to the high-altitude construction platform with a crane, and then install and position them one by one manually with the crane. The disadvantage of this method is that the process takes up It takes a long time and the efficiency of the crane operation is low. It is extremely difficult to manually install a single large-diameter super-long steel bar, and the installation accuracy is difficult to guarantee; another method is to install it with a crane after the overall binding of the steel frame is completed. During the process, the steel skeleton is easily deformed, and a large number of auxiliary devices need to be invested for reinforcement. It is difficult to connect the upper and lower steel skeletons, and the precision is difficult to control.

In the prior open technology, such as Publication No.: CN 204434056 U "Steel Bar Hanger", a steel bar hoisting device consisting of two crossbeams is introduced, and the crossbeam is provided with round holes for fixing the steel bars. This device only fixes the upper part of the steel bar. If the hoisted steel bar is large-diameter and super-long, no limit measures are taken at the bottom after hoisting. Under the influence of wind load and partial partial load, the bottom of the long steel bar swings randomly, which is very easy Insufficient overall stability results in a certain safety risk, and at the same time may cause deformation and damage to the steel bar. Therefore, the device has certain limitations and the scope of application is small.
