Abstract
The present invention relates to a method for horizontally-welding reinforcement and its welding die assembly. It is characterized by that said invented welding method uses the are-striking current or an electrode to make welding between end surfaces of two reinforcement bars in a die assembly, and the weld joints are placed in molten pool, so that the reinforcement bars are fusion-welded together by means of electric arc heat produced by arc welding. Said inventedspecial-purpose welding die assembly consists of two portions of bottom die and upper die. The bottom die is a copper die block with semi-circular recess and half-round molten pool in its central position and the upper die is a copper die block whose central position is equipped with an opened cone welding groove whose position is corresponding to the molten pool of the bottom die. Said invention is not limited in environment and site and simple in operation, etc.
Description
The present invention relates to a kind of horizontal steel bar welding method and mould, the diameter steel bar that is particularly useful in the architectural engineering connects.
It is important construction technology that has a large capacity and a wide range in the architectural engineering that thick diameter muscle connects, and is directly connected to security, speed of application and the overall economic efficiency of building structure.The bar reinforcement method of attachment comprises three kinds of colligation, welding and machineries, and the binding method consumptive material is many, and joint is stressed poor; Welding method has overlap joint arc welding, electroslag welding, gas pressure welding etc., and butt joint requires the level height, need buy complete welding machine, and, voltage instability and place narrow occasion poor at condition of power supply should not be used; The cost of mechanical connection is higher.92220383 patent disclosures the U pattern tool of a kind of reinforcing bar level welding, adopt manual electric arc welding to finish the butt joint of reinforcing bar.Problems such as the insulation contact-making surface of this U pattern tool and reinforcing bar has only semicircle, and workman's operating technology is had relatively high expectations, and easily causes " through welding " in welding process, and moulding is lack of standardization, and hot temperature inequality of welding arc and deslagging are not smooth.
The object of the present invention is to provide the method and the mould of the layering arc-welding in particular manufacturing craft of a kind of horizontal steel bar, mainly solve the job site and simplify the operation, the geometry of control splice guarantees that welding quality is equal to topic.
Technical scheme of the present invention is achieved in that this horizontal steel bar welding method, utilize welding rod striking electric current, in mould, weld between the two reinforcing bar end faces, form a molten bath at weld pattern tool, playing insulation and thermostatic effect, help deslagging simultaneously, is the key of welding quality, welding rod is radially from bottom to top back and forth transported arc between the reinforcing bar end face, the layering welding.Welding point produces arc heat by arc-welding reinforcing bar is welded together in the molten bath.
Described horizontal steel bar welding method, select for use the parameter of core diameter and welding current to be according to bar diameter:

Described horizontal steel bar welding method is soldered to every layer of current interruption 2-3 second in 2/3 when height in the molten bath, in order to avoid temperature is too high, fortune arc angle is less than 30 degree, and is full until weldering.
This horizontal steel bar welding particular manufacturing craft of the present invention is made up of bed die (1) and patrix (2) two parts, and bed die is the copper module that has semicircle groove, and the bed die middle part has semicircle molten bath (3); Patrix is the copper module that the middle part has taper weld bond (4), and the weld bond position is corresponding with the bed die molten bath.
Described horizontal steel bar weld mold is according to also being provided with on the need of work mould and the fixing fixing jig (5) of mould up and down that reaches of reinforcing bar.
Adopt horizontal steel bar welding method of the present invention and mould not to be subjected to the restriction in environment, place, simple to operate, easy to maintenance, welding quality guarantees that easily general welder both can on dutyly operate through training in 1-2 days.On industry, promote the use of, have tangible economic benefit.
Describe technology contents of the present invention in detail below in conjunction with embodiment and accompanying drawing:
