Existing Patents in prior art, as the patent No. " 201320335709.8 ", name is called " waveform butt weld steel tube tower ", this patent content is: comprise at least two steel pipes, described steel pipe is all arranged and welding up and down vertically, it is characterized in that: the tube wall of end in opposite directions of two steel pipes of arbitrary neighborhood is all provided with waveform interface separately, the coincident of two waveform interfaces of arbitrary neighborhood, two adjacent waveform interfaces are along the welding of moving towards at its edge;
Although this technical scheme can increase fusion length, improve weld strength; But still there is defect: soldering opening arranges undulate, because steel pipe is circular, its difficulty of processing is large, processing cost is high, and long processing time, high to fit dimension required precision at assembling process, easily occur causing scrapping or processing again because of dislocation, inefficiency, operating process complexity etc.
Summary of the invention
Technical problem to be solved by this invention is, for the shortcoming of above prior art, to propose a kind of rectangle butt weld steel pipe for communications tower, not only greatly increased fusion length, improved weld strength, compactness is good, by engaging between groove and boss, bulk strength is high, assembles simple and convenient, increase work efficiency, good looking appearance, safer more reliable, and processing is simple, dimension precision requirement is low, reduces costs, easy to maintenance.
In order to solve the problems of the technologies described above, technical scheme of the present invention is achieved in the following ways: a kind of rectangle butt weld steel pipe for communications tower, comprise at least two steel pipes, steel pipe is axially arranged in order along it, and adjacent steel pipe welds at joint, steel pipe one end, two ends is vertically provided with rectangular recess, the other end is provided with rectangular boss, rectangular recess and rectangular boss are uniform at steel pipe circumferencial direction, the rectangular boss of any two adjacent steel pipe junctions can be inserted rectangular recess, the rectangle interface of adjacent two steel pipe junctions is along the welding of moving towards at its edge.
Like this, by technical scheme of the present invention, at the joint of steel pipe, rectangle weld seam is set, not only greatly increased fusion length, improved weld strength, compactness is good, by engaging between groove and boss, bulk strength is high, assembles simple and convenient, increase work efficiency, and good looking appearance, safer more reliable, processing is simple, and manufacturing process is many, and processing cost is low, dimension precision requirement is low, reduces costs, easy to maintenance.
The technical scheme that the present invention further limits is:
The aforesaid rectangle butt weld steel pipe for communications tower, in the developed surface of steel pipe, its upper end-face edge or lower edge or upper end-face edge and lower edge are the rectangular shape of consecutive intervals rectangular recess and rectangular boss, adopt rectangular shape, simple in structure, easily processing, assembling is simple.
The aforesaid rectangle butt weld steel pipe for communications tower, the rectangle interface of adjacent two steel pipe junctions is equipped with welding groove on the edge of contact, and welding groove is set, and improves its weld strength, increases the safety and reliability of steel pipe.
The aforesaid rectangle butt weld steel pipe for communications tower, the quantity of rectangular recess and rectangular boss equates and quantity is even number, quantity is arranged to even number, convenient processing, assembling coordinates simple, increases work efficiency.
The aforesaid rectangle butt weld steel pipe for communications tower, the size of rectangular recess and rectangular boss is identical, and the edge that rectangular recess contacts with rectangular boss overlaps, and improves like this steel pipe integral intensity, improves safety.
The invention has the beneficial effects as follows: by technical scheme of the present invention, at the joint of steel pipe, rectangle weld seam is set, has not only greatly increased fusion length, improved weld strength, compactness is good, by engaging between groove and boss, bulk strength is high, assembles simple and conveniently, increases work efficiency, and good looking appearance, safer more reliable, processing is simple, manufacturing process is many, and processing cost is low, and dimension precision requirement is low, reduce costs, easy to maintenance.
Welding groove is set, improve its weld strength, increase the safety and reliability of steel pipe, the quantity of rectangular recess and rectangular boss equates and quantity is even number, and quantity is arranged to even number, convenient processing, assembling coordinates simple, increases work efficiency, and the edge that rectangular recess contacts with rectangular boss overlaps, improve like this steel pipe integral intensity, improve safety.
