Large-diameter reinforced net and method for butt-joint connection of large-diameter reinforced net through connecting rods

Abstract

The invention provides a large-diameter reinforced net which comprises a plurality of large-diameter reinforced net units. Two oppositely-arranged main steel bars in every two adjacent large-diameter reinforced net units are connected through connecting rods. The large-diameter reinforced net provided by the invention is formed by connecting the multiple prefabricated large-diameter reinforced net units in a butt-joint mode through the connecting rods, operation is simple, and mechanical connection of the large-diameter reinforced net can be conveniently and fast achieved through a rotation function, a length adjusting function and a moderate swinging function of the connecting rods. The invention provides a method for butt-joint connection of the large-diameter reinforced net units through the connecting rods at the same time. By adoption of the method, an integral hoisting and butt-joint process achieved by prefabricating the large-diameter reinforced net units on the ground replaces a one-by-one mounting and butt-joint process of large-diameter reinforcing steel bars in the high altitude in existing projects, the problem that the prefabricated large-diameter reinforced net cannot be formed through integral butt-joint on site is solved, and the construction speed of reinforcing steel bar engineering is greatly increased.

Description

technical field [0001] The invention relates to a reinforcement mesh, in particular to a large-diameter reinforcement mesh and a method for connecting the large-diameter reinforcement mesh with a connecting rod. Background technique [0002] At present, under the background of the national development strategy of "going out" of nuclear power engineering technology, solving the overall butt joint technology of large-diameter steel mesh pieces at the construction site of nuclear power plants is a key technology to shorten the construction period of nuclear power projects and increase investment benefits. Among them, the large-diameter steel mesh sheet refers to the steel mesh sheet prefabricated by steel bars with a diameter not less than 16mm. [0003] In the construction of my country's nuclear power plants, regardless of whether France, Russia, the United States or my country's own nuclear power technology is used, the engineering volume of large-diameter steel bar connecti...

Problems solved by technology

But so far, there has been no breakthrough in this technology. The commonly used steel mechanical connection joints (straight thread joints) cannot adapt to the steel bar axis deviation and length error caused by the production and installation of the steel mesh, making the straight thread sleeve The cylinder cannot be smoothly screwed into the steel wire head in the corresponding steel mesh sheet to be connected
