Description

An adjustable steel cage hanger

technical field

The utility model belongs to the technical field of hangers, in particular to an adjustable steel cage hanger.

Background technique

With the popularization of bridge prefabricated assembly construction technology in urban bridge construction, bridge construction is gradually moving towards standardization, unitization, normalization and factoryization. Among them, in the large-scale production of prefabricated columns and cover beams, the steel cage prefabricated parts produced as a whole need to be hoisted as a whole and transported to the formwork for pouring into the mold. It is a two-point hoisting method, such as using two slings or pole beams to hoist the reinforcement cage. When using two slings for hoisting, generally a lifting point is set at the end and tail of the reinforcement cage, and the end of the reinforcement cage is used When lifting by a large crane, use a small crane or loader to lift the tail of the steel cage. Lifting in this way will easily cause the middle part of the steel cage to bend, deform the middle part of the steel cage, and cause difficulties for the vertical bottom of the steel cage. When hoisting with pole beams, this hoisting method is to use the main hook on the crane, pole beams, and slings to achieve hoisting. A pulley is installed at both ends of the pole beam, and a sling is installed on each pulley. The two ends of the sling The ends are respectively installed on the reinforcement bars on the upper part of the steel cage through fasteners, thus forming two lifting points. The pole beam has the following disadvantages when hoisting the steel cage: 1. When the pole beam is hoisting a large-diameter steel cage, it is easy to make the steel cage The upper part is deformed, which causes damage to the steel cage; 2. The force of the steel cage is unbalanced during hoisting, and it is prone to tilting, resulting in safety accidents; 3. For heavy steel cages, the two stress points are easy to make The reinforcing bars above the reinforcement cage were detached from the reinforcement cage, resulting in the failure of lowering the reinforcement cage. In short, when two-point hoisting is used, the stability and applicability are poor, and it is easy to damage the steel cage structure and even cause dangerous accidents.
