Description

A welded steel bar net for bridge pavement

Technical Field

The utility model relates to a welded steel bar net technical field, concretely relates to welded steel bar net for bridge mating formation.

Background

In the construction industry, welded mesh reinforcement has been widely used in various construction processes, such as bridge construction. The welded steel bar net is a steel bar net piece formed by arranging a plurality of longitudinal bars and a plurality of transverse bars at certain intervals and forming right angles with each other, and all cross points are welded together by welding. Because part of the bridge is designed into an arch shape, the difficulty of splicing the welded steel bar mesh on site is high in the process of erecting the welded steel bar mesh, and the construction efficiency is low; and the bearing capacity of the welding point where the adjacent steel bar welding nets are directly spliced and welded is lower.

Disclosure of Invention

An object of the utility model is to overcome the defect that exists among the prior art, provide a simple structure, be convenient for the concatenation, improve concatenation welding point bearing capacity and can adapt to the steel bar welding net that is used for the bridge to mat formation of multiple concatenation angle.

In order to achieve the purpose, the technical scheme of the utility model a design a welded steel bar net for bridge is mated formation, including many horizontal muscle and many vertical bars, horizontal muscle with vertical bars arranges and each other becomes the right angle cross welding with certain interval respectively, forms a plurality of square grids that the size is the same, horizontal muscle with vertical bars's one end has the circular arc bending segment, sliding sleeve is equipped with the drum on the circular arc bending segment. The tip of the muscle that indulges of welded-bar mesh and horizontal muscle has the circular arc buckling segment, the drum is established to slip cap on the circular arc buckling segment, during the concatenation, according to the concatenation angle of bridge design demand, the position of adjustment slip drum, cut unnecessary circular buckling segment, then carry out welded connection with the horizontal muscle of second welded-bar mesh or the horizontal muscle of indulging muscle and first welded-bar mesh with indulging the muscle again, then the cylinder that slides again shelters from the cladding with the welding point of indulging muscle or horizontal muscle, at last with the drum with the vertical muscle or the horizontal muscle welded fastening of concatenation, the multiple concatenation angle that has improved concatenation welding point bearing capacity and can adapt to welded-bar mesh, the application scope of welded-bar mesh is improved.

In order to avoid the situation that the cylinder slides down from the transverse bar or the longitudinal bar when the welded steel bar mesh is stored, transported or used, the preferable technical scheme is that a stop block used for stopping the cylinder from sliding down is arranged at the end point of the arc bending section.

In order to facilitate the same sliding of the cylinders on the welded steel bar mesh and the cutting of redundant longitudinal bars and transverse bars, a further preferred technical scheme is that the welded steel bar mesh is further provided with a synchronizing rod, and the synchronizing rod is connected with the outer wall of each cylinder on one side of the welded steel bar mesh. When the cylinders need to slide, the cylinders do not need to slide one by one, and all the cylinders on one side of the steel bar welding net can slide synchronously only by pulling the synchronizing rods, so that the working efficiency of workers is improved.

In order to reduce the thickness of the welded steel mesh, it is further preferable that the axis of the synchronization rod passes through the midpoint of each cylinder connected thereto.

The technical scheme is that the steel bar welding net is further provided with circular reinforcing ribs, and the circular reinforcing ribs are internally tangent to four sides of the square grids.

In order to further strengthen the stability of the welded steel bar net and improve the strength of the welded steel bar net, the further preferred technical scheme is that a plurality of arc sections are evenly arranged on the transverse bar, and the transverse bar and the longitudinal bar are welded in a crossed mode through the arc sections. Indulge the muscle and pass through the arc section cross welding with horizontal muscle, improve the area of contact and the welding area at intersect, can effectively increase the steadiness of welded reinforcement net.

The utility model has the advantages and the beneficial effects that: the steel bar welding net has the characteristics of simple structure, convenience in splicing, improvement in the bearing capacity of splicing welding points and capability of adapting to various splicing angles. The utility model discloses a longitudinal reinforcement and the tip of horizontal muscle of welded steel bar net have circular arc bending section, the drum is established to the slip cap on the circular arc bending section, during the concatenation, according to the concatenation angle of bridge design demand, the position of adjustment slip drum, cut unnecessary circular bending section, then weld the horizontal muscle or the vertical muscle of second welded steel bar net and the horizontal muscle and the vertical muscle of first welded steel bar net and be connected, then slide the drum again and shelter from the cladding with the welding point of vertical muscle or horizontal muscle, finally weld drum and the vertical muscle or the horizontal muscle of concatenation and fix, improved concatenation welding point bearing capacity and can adapt to the multiple concatenation angle of welded steel bar net, improve welded steel bar net's application scope; the synchronous rods are arranged on the cylinders, when the cylinders need to slide, the cylinders do not need to slide one by one, and all the cylinders on one side of the steel bar welding net can slide synchronously only by pulling the synchronous rods, so that the working efficiency of workers is improved; indulge the muscle and pass through the arc section cross welding with horizontal muscle, improve the area of contact and the welding area at intersect, can effectively increase the steadiness of welded reinforcement net.
