Reinforcement cage leveling method based on reinforcement cage leveling equipment

Abstract

The invention discloses a reinforcement cage leveling method based on reinforcement cage leveling equipment. The reinforcement cage leveling method comprises the following steps of 1, building a reinforcement cage finite element model and determining the gravity centers of all levels of a reinforcement cage; 2, determining the effective length of a leveling beam; 3, positioning a reinforcement cage connecting lifting lug and a main lifting lug; 4, determining the number of connecting lifting ropes and calculating the length of each connecting lifting rope; 5, connecting the leveling beam withthe reinforcement cage; 6, connecting an assisting lifting rope; and 7, performing reinforcement cage leveling. According to the reinforcement cage leveling method based on the reinforcement cage leveling equipment, the reinforcement cage finite element model corresponding to the reinforcement cage is established, the gravity centers of the different levels of the reinforcement cage are determinedin a computer, and the effective length of the leveling beam is limited by utilizing the distance between the two (n+1) stages of gravity centers of the two ends of a plurality of (n+1) stages of gravity centers on the reinforcement cage, so that the reinforcement cage connecting lifting lug and the main lifting lug are positioned; and arranging the connecting lifting ropes with adaptive lengthsbetween lifting points and the reinforcement cage connecting lifting lug, and suspending the edge of the reinforcement cage by using the assisting lifting rope, so that the deformation, caused by self-weight, of the edge of the reinforcement cage is avoided; and the leveling effect is good.

Description

technical field [0001] The invention belongs to the technical field of steel cage horizontal hanging, in particular to a steel cage horizontal hanging method based on steel cage horizontal hanging equipment. Background technique [0002] With the development of my country's economy, there are more and more large-scale industrial plants and logistics warehouses in engineering construction, and steel structures, PC, and cast-in-place concrete composite structures are often used. The key to the installation of PC components and roof trusses. The length of steel cages adopted in building construction is getting longer and longer. In the existing construction, most of the hoisting of the steel cage is from horizontal to vertical. It is not necessary to consider whether the horizontal hoisting of the steel cage is real-time level, so the setting of the lifting points of the steel cage seems random, the number of lifting points is small, and the spacing is large , and the force of...

Problems solved by technology

In the existing construction, most of the hoisting of the steel cage is from horizontal to vertical. It does not need to consider whether the horizontal hoisting of the steel cage is real-time level, so the setting of the lifting points of the steel cage seems random, the number of lifting points is small, and the spacing is large , and the force of each lifting point is often different, so the reinforcement cage is prone to large bending deformation under the action of its own weight during the lifting process, which will affect the subsequent lowering of the reinforcement cage and cause unnecessary assembly of the column reinforcement cage and the column formwork on the ground. In severe cases, it will affect the strength of the post-formed column, posing a safety hazard
