Three kinds of welded meshes of deformed rebars and preparation method

Abstract

The invention discloses three kinds of welded meshes of deformed rebars and a preparation method, belongs to the technical field of building engineering, and relates to rebar processing technology andequipment, in particular to welded meshes of deformed rebars and the preparation method. By providing the technical scheme for processing and producing the welded meshes of the deformed rebars, not only can the welded meshes of the deformed rebars at the bottom of a concrete slab be processed and produced, but also the welded meshes of the deformed rebars at the top of the corner of the concreteslab and the welded meshes of the deformed rebars at the top of the side of the concrete slab can be processed and produced. Since end rebars are bent up, the welded meshes of the deformed rebars areanchored into the top of a support from the top of the support, the welded meshes of the deformed rebars can be placed after other rebars at the support are bound. The preparation method of the weldedmeshes of the deformed rebars can realize the factory, large-scale and mechanized production of the welded meshes of the deformed rebars, has high production efficiency, good product quality, and lowprocessing cost, decreases the raw material consumption, greatly reduces the labor demand for binding the rebars, meets requirements of environmental protection and adapts to the development trend ofindustrialization of construction industry.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to steel bar processing technology and equipment, in particular to a special-shaped steel bar welded mesh and a preparation method. Background technique [0002] Welded steel mesh is a mesh in which longitudinal steel bars and transverse steel bars are arranged orthogonally at a certain distance, and all intersections are spot welded together. Welded steel mesh is especially suitable for floor slabs of concrete structures. Welded steel mesh can be produced in a factory, on a large scale and mechanized, with high production efficiency, good product quality, low processing cost, saving raw material consumption, greatly reducing the labor demand for binding steel bars, meeting the requirements of environmental protection, and adapting to the development trend of industrialization of the construction industry. [0003] At present, the welded steel mesh used...

AI Technical Summary

Problems solved by technology

[0004] Flat-shaped welded steel mesh is mainly used for laying the bottom reinforcement of concrete floor slabs. However, for the application of welded steel mesh to concrete structure floor slabs, there is a huge application obstacle, that is, the use of welded steel mesh for floor slabs will hinder The binding of steel bars on floor beams and walls at floors has become a difficult problem to solve

This is because when the formwork is completed, the floor reinforcements are bound. If the welded steel mesh at the bottom of the slab is laid first, the steel bars at the bottom of the welded steel mesh need to go deep into the support, and then the steel bars on the floor beam and the wall at the floor are bound because of the steel bars. The obstruction of the welded mesh will be very difficult, and the phenomenon of nesting is very serious; if the floor beams and the steel bars on the walls of the floors are bound first, the welded steel mesh used for the bottom of the floor slab will not be able to fall to the designed position due to its blocking effect; In order to solve this problem, the usual practice is that the welded steel mesh at the bottom of the floor slab does not extend into the support. After all the steel bars are bound, a short steel bar section is arranged at the support to extend into the support and connect with the steel bars outside the support. Welded mesh lap connection, the problems of doing so are: first, a large amount of lap connection length wastes steel bars, and second, the quality of the connection is not easy to control

These existing problems have seriously restricted the application of welded steel mesh in concrete floors and even construction projects.
