Machining device for ultra-long and ultra-large steel reinforcement framework and hoisting device and method

Abstract

The invention discloses a machining device for an ultra-long and ultra-large steel reinforcement framework. The machining device comprises a front row of vertical rods and a rear row of vertical rodswhich are correspondingly arranged, wherein each row of vertical rods comprises a plurality of vertical rods; the upper part; the middle part and the bottom end of each row of vertical rods are connected with an upper horizontal connecting rod; a middle horizontal connecting rod and a lower horizontal connecting rod respectively; the upper horizontal connecting rods; the middle horizontal connecting rods and the lower horizontal connecting rods are fixedly connected with each vertical rod in the row of vertical rods; a plurality of distribution beams for uniformly distributing lifting force are arranged between the upper horizontal connecting rods of the front row of basic structures and the rear row of basic structures; and the distribution beams are placed at the tops of the upper horizontal connecting rods. The invention further discloses a corresponding hoisting device and a hoisting method. The hoisting method comprises the steps of manufacturing the steel reinforcement framework,mounting a template bracket, clearing a field, hoisting, lowering and guiding, putting into a groove and the like. With the adoption of the technical scheme, the working efficiency is improved, potential safety hazards are reduced, the ultra-long and ultra-large steel reinforcement framework is prevented from being locally or wholly deformed in a hoisting process, a very accurate mounting position is guaranteed and the hoisting quality is greatly improved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to the hoisting technology of large-scale reinforced skeletons. Background technique [0002] The prefabricated equipped bridge pier top crossbeam can not only effectively connect multiple box rooms into a whole, but also play the role of assembling 0# blocks of bridge segments. Its steel bars have many types, large quantities, and dense spacing, and at the same time make way for prestressed tendons , and the amount of concrete is large and the shape is complex, the construction process is extremely troublesome. If the steel skeleton is made by tying in situ at the design height of the structure, the construction will be more troublesome due to the high-altitude factor involved, the efficiency will be difficult to improve, the quality cannot be guaranteed, and there will be great hidden dangers in construction safety.

Problems solved by technology

[0002] The prefabricated equipped bridge pier top crossbeam can not only effectively connect multiple box rooms into a whole, but also play the role of assembling 0# blocks of bridge segments. Its steel bars have many types, large quantities, and dense spacing, and at the same time make way for prestressed tendons , and the amount of concrete is large and the shape is complex, the construction process is extremely troublesome

If the steel skeleton is made by tying in situ at the design height of the structure, the construction will be more troublesome due to the high-altitude factor, the efficiency will be difficult to improve, and the quality will not be guaranteed.

If it is transported after prefabrication in the factory, it is also very inconvenient because of the large size and long distance

[0003] If the binding of the steel frame is carried out on the original ground near the design position of the structure, it will be much more convenient and the construction efficiency will be significantly improved compared with the previous prefabricated and transported steel frame or the binding and production of the steel frame at the target position where the steel frame is installed. Potential safety hazards will be reduced, but when hoisting the steel frame after construction to the design position, due to the self-weight, flexibility of the steel bar itself and the firmness of the connection at the binding point, the traditional lifting method will cause deformation of the large steel frame after hoisting. Furthermore, the steel bars may shift or even fall off, and the deformation of the steel bar skeleton after hoisting will also lead to difficulties in installation and positioning, and it is also difficult to adjust the deviation
