Pull-type reinforcement mesh braiding machine and method for braiding reinforcement mesh by pull-type reinforcement mesh braiding machine

Abstract

The invention provides a pull-type reinforcement mesh braiding machine and a method for braiding a reinforcement mesh by the pull-type reinforcement mesh braiding machine. The pull-type reinforcementmesh braiding machine and the method can improve the reinforcement binding efficiency and project efficiency. The pull-type reinforcement mesh braiding machine comprises an underframe, a plurality ofcomb plates, a comb plate lifting mechanism, a longitudinal rib locating mechanism and a travelling traction mechanism; a plurality of travelling wheels are arranged at the bottom of the underframe; aplurality of rollers are arranged at the end of the underframe; the comb plates are arranged in parallel in a spaced manner in the width direction of the underframe; the comb plate lifting mechanismis arranged in the length direction of the underframe, is arranged below the comb plates and is connected with the comb plates; the longitudinal rib locating mechanism comprises a plurality of groupsof guide rolls and is arranged in the length direction of the underframe; each group of guide rolls comprises two guide rolls arranged up and down; the travelling traction mechanism comprises electrictractors; the electric tractors are arranged on the underframe; and steel wire ropes on the electric tractor are connected with guardrails of a to-be-constructed bridge.

Description

technical field [0001] The invention relates to a steel mesh weaving machine, in particular to a traction-type steel mesh weaving machine and a method for weaving steel mesh pieces, belonging to the field of construction machinery. Background technique [0002] Reinforcement mesh is made of cold-rolled ribbed steel bar vertically and horizontally to form a mesh structure at a certain distance, which is widely used in bridge engineering, concrete pavement engineering, airport runway, tunnel lining, industrial and civil construction floor slabs, etc. [0003] Especially in bridge engineering, the network structure formed by the longitudinal bars and transverse bars of the steel mesh has good bonding and anchoring properties with the concrete of the bridge deck pavement, and the bearing load can be evenly spread and distributed, which significantly improves the seismic and crack resistance of reinforced concrete structures. [0004] Although there is a certain degree of flexibi...

AI Technical Summary

Problems solved by technology

[0004] Although there is a certain degree of flexibility and convenience in traditional manual binding on site, there are the following problems: 1. The efficiency of traditional manual binding is low; Construction workers; 3. It is difficult to control the quality of traditional manual binding. Traditional manual binding is to control the spacing by springing wires on the bridge surface. Mesh Distortion

[0005] The following problems exist in the construction of finished steel mesh: 1. The finished steel mesh is produced off-site, and the product specification and size are limited by transportation conditions. The size of a single mesh cannot exceed the relevant transportation requirements. At the same time, the purchase cost is considered comprehensively. In addition, the variety should not be too many, so that it cannot match the diversity of bridges on site, increasing the overlap between the steel mesh and increasing the actual amount of mesh, in the actual bridge deck pavement construction , due to the different overlapping methods, under normal circumstances, the amount of material used is close to 10% higher than the theoretical amount; 2. The steel mesh is installed on-site by overlapping one by one, and the longitudinal and transverse joints are staggered, causing the eight-strand steel bars of the local four-layer mesh to overlap. It is very easy to cause insufficient thickness of the protective layer, and in serious cases, the problem of exposed ribs will occur; 3. The factory production of the mesh, the singleness of the appearance type, and the actual use of the bridge type and bridge span type, especially the simple support first and then continuous There are bridges and other situations where positive and negative bending moments alternate on the bridge deck, and there are strict requirements on the position of the lap joint of the mesh in the negative bending moment area, so it is difficult to unify the singleness of the product and the diversity of actual needs
