Abstract

The utility model aims at providing a structure for welding large-diameter building steel bars, which is used for firmly welding two short steel bars, and belongs to the field of construction and building materials. According to the structure for welding large-diameter building steel bars, a welding base material A and a welding base material B are superposed; reinforcement plates are arranged on the two sides of a contact gap between the welding base material A and the welding base material B; one end surface of each reinforcement plate is aligned to the end surface of the welding base material A; the other end surface of each reinforcement plate is aligned to the welding base material B; an end surface weld joint is formed at the part of contact between the side surface of the welding base material A and the end surface of the welding base material B or between the side surface of the welding base material B and the end surface of the welding base material A; side surface weld joints are formed at the parts, where the reinforcement plates make contact with the welding base materials A and B, of the reinforcement plates; internal weld joints are formed at the part of contact between the side surfaces of the welding base materials A and B and in the reinforcement plates. The structure for welding large-diameter building steel bars is simple to operate and firm in welding; one reinforcement plate and two welding points are arranged, so that firmer welding is achieved, namely the bearing strength is enhanced, the problem of open weld is effectively prevented, the danger coefficient is reduced, and various losses cannot be caused.

Description

Major diameter building bar welded construction

Technical field

The utility model belongs to building materials field.

Background technology

Reinforcing bar is the requisite material of building field, due to affected by environment, sometimes need bar dowel, sometimes need long reinforcing bar, also relatively good processing while needing bar dowel, and need to long reinforcing bar time, if be directly processed into sufficient length, transportation is got up just pretty troublesome and dangerous, so generally only block, then to workplace, weld use, yet existing welding is only simple butt welding, so very easily snap when load-bearing is larger, the load-bearing of not only impact building, may cause again the loss of danger and personnel, economy.

Summary of the invention

The purpose of this utility model is to provide two bar dowels welded together, and the major diameter building bar welded construction of firm welding.

Welding base metal A of the present utility model and welding base metal B are stacked, and the both sides, gap that contact at welding base metal A and welding base metal B are all placed with stiffener, an end face of stiffener aligns with welding base metal A end face, another end face of stiffener aligns with welding base metal B, there is edge weld contact site at welding base metal A side and welding base metal B end face or welding base metal B side and welding base metal A end face, stiffener has fillet in parallel shear with welding base metal A and welding base metal B contact site respectively, welding base metal A and welding base metal B contacts side surfaces position, and there is internal weld seams in stiffener inside.

The utility model is simple to operate, and firm welding, by increasing a stiffener and a plurality of pad, has reached more firmly welding, has strengthened load bearing stength, has effectively prevented from again the problem of snapping from having reduced danger coefficient, also can not cause various losses.

Fig. 2 is that the A-A of the utility model Fig. 1 is to view;

In figure, 1 is welding base metal A; 3 is stiffener; 4 is fillet in parallel shear; 5 is welding base metal B; 6 is internal weld seams.

The specific embodiment

The utility model welding base metal A1 and welding base metal B5 are stacked, and the both sides, gap that contact at welding base metal A1 and welding base metal B5 are all placed with stiffener 3, an end face of stiffener 3 aligns with welding base metal A1 end face, another end face of stiffener 3 aligns with welding base metal B5, there is edge weld 2 contact site at welding base metal A1 side and welding base metal B5 end face or welding base metal B5 side and welding base metal A1 end face, stiffener 3 has fillet in parallel shear 4 with welding base metal A1 and welding base metal B5 contact site respectively, welding base metal A1 and welding base metal B5 contacts side surfaces position, and there is internal weld seams 6 in stiffener 3 inside.Wherein can to adopt multipoint mode spot welding can be also the long weldering of carrying out whole side to fillet in parallel shear 4.
