Integrated construction equipment for binding and lifting continuous beam steel reinforcement framework and construction method

Abstract

The invention discloses integrated construction equipment for binding and lifting a continuous beam steel reinforcement framework. The integrated construction equipment is characterized in that a steel reinforcement binding fixture for binding the steel reinforcement framework is arranged on a cast bridge floor, a truss-type slide lifting appliance is longitudinally arranged above the steel reinforcement binding fixture, the front end of the truss-type slide lifting appliance is supported on a front upper beam of a cradle through a front end support, the tail end of the truss-type slide lifting appliance is supported on the cast bridge floor through a tail support, a crown block is mounted on the truss-type slide lifting appliance, and the steel reinforcement framework can be integrally lifted via a steel reinforcement hanger lifted by the crown block. The steel reinforcement binding fixture is mounted on the constructed bridge floor and used for binding the steel reinforcement framework, steel reinforcements are lifted into the cradle by the truss-type slide lifting appliance, steel reinforcement binding and beam section construction are realized simultaneously, and construction time is greatly shortened.

Description

technical field [0001] The invention relates to construction equipment and a construction method for binding, hoisting and installing steel bar skeletons in the construction of continuous beam hanging baskets, and is especially applied in the construction of continuous beams of down-supported hanging baskets. Background technique [0002] In the construction of continuous beams, the traditional construction method is to use the upper hanging basket, and the steel bars are bound inside the hanging basket on site. This method has the following problems: [0003] 1. Due to the narrow operating space inside the hanging basket, it is difficult to control the quality of steel bar binding; [0004] 2. In the construction of continuous beams, the steel bar binding operation process can only be carried out in the flow of the entire continuous beam construction, and cannot be operated in parallel, which takes up a lot of time and makes the construction period unable to be effectively ...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the narrow operating space inside the hanging basket, it is difficult to control the quality of steel bar binding;

[0004] 2. In the construction of continuous beams, the steel bar binding operation process can only be carried out in the entire continuous beam construction, and cannot be operated in parallel, which takes up a lot of time and prevents the construction period from being effectively shortened.

[0006] 1. In order to complete the lashing and overall hoisting outside the site, it is necessary to open up another site for tying steel bars. This solution cannot be realized when there are no tying and hoisting sites such as crossing rivers or ravines, and the on-site tying method can only be used

[0007] 2. Since the size of the reinforced steel skeleton after binding is 425×350×1200cm and weighs 8 tons, even though it is possible to invest in large-scale hoisting equipment and meet the hoisting conditions for the overall hoisting, there are still considerable construction safety hazards. high construction cost
