Embodiment 1

[0034] Such as figure 1 with figure 2 As shown, the present invention includes the following steps:

[0035] (1) Place the first steel pipe between the two third fixed plates 6 on the second fixed plate 2, and adjust the distance between the two third fixed plates 6 by extending and retracting the third telescopic plate 5 so that the first A steel pipe is fixedly placed between the two third fixing plates 6;

[0036] (2) Place the second and third steel pipes to be welded between the two fixing plates 11 on the first fixing plate 1, and expand and contract the first and second expansion plates 9 and 10 to make the first The second and third steel pipes are fixedly placed between the two fixing plates 11, so that the second and third steel pipes are adjusted to the required angle, and their lower ends are in contact with the side of the first steel pipe;

[0037] (3) Adjust the distance between the first fixing plate 1 and the second fixing plate 2 by rotating the connecting rod 14...

Embodiment 2

[0043] The truss welding method for welding multiple steel pipes with different angles at the same time of the present invention includes a steel pipe for welding as a truss and a fixing device for fixing the steel pipe. The fixing device includes a first fixing plate 1 and a second fixing plate 2. The first fixing plate 1 is located directly above the second fixing plate 2. The first fixing plate 1 is provided with a first through groove 8 in its length direction. The first through groove 8 equally divides the first fixing plate 1 into two small fixing plates, The opposite surfaces of the two small fixed plates are respectively provided with a first telescopic plate 9 and a second telescopic plate 10 that extend and contract in the width direction of the first fixed plate 1 on the horizontal surface, and the first telescopic plate 9 and the second telescopic plate 10 are opposite to each other. One end of the steel pipe is vertically connected with a fixing plate 11 for fixing ...

Embodiment 3

[0045] On the basis of Embodiment 2, the connecting rod 14 is fixed and sleeved with a stabilizing plate 16, and the connecting rod 14 and the stabilizing plate 16 are provided with corresponding convex grooves and grooves, and the stabilizing plate 16 rotates around the axis of the connecting rod 14. And the stable plate 16 is fixedly connected with the upper end of the rotating rod 15. When the rotating rod 15 is rotated, the stable plate 16 is driven to rotate; the lower ends of the rotating rod 15 and the connecting rod 14 and the inner bottom of the second fixing plate 2 are provided with corresponding slots , The lower ends of the rotating rod 15 and the connecting rod 14 are fixedly connected to the inner bottom of the second fixed plate 2, and the rotating rod 15 and the connecting rod 14 rotate on the inner bottom of the second fixed plate 2 along its axis; the upper end of the rotating rod 15 The distance from the upper end of the second fixing plate 2 is 8 cm. The he...

Abstract

The invention discloses a truss welding method for welding multiple steel pipes of different angles simultaneously. The method comprises the steps that the first steel pipe is placed between two thirdfixing plates on a second fixing plate, the second steel pipe and the third steel pipe which are to be welded are placed between two fixing plates on a first fixing plate, and the lower end of the second steel pipe and the lower end of the third steel pipe are enabled to make contact with the side face of the first steel pipe; the distance between the first fixing plate and the second fixing plate is adjusted by turning a rotary connecting rod, the distance between a connecting plate and the inner bottom of the second fixing plate is adjusted by turning a rotary rod, and welding is carried out on welding points, among the first steel pipe, the second steel pipe and the third steel pipe, between the first fixing plate and the second fixing plate. The truss welding method for welding multiple steel pipes of different angles simultaneously is simple in device structure, and convenient to operate and use.

Description

Technical field [0001] The invention relates to the field of construction, in particular to a truss welding method for simultaneously welding multiple steel pipes with different angles. Background technique [0002] Truss: A structure in which rods are connected to each other by hinges at both ends. The truss is composed of straight rods and generally has a plane or space structure with triangular elements. The truss members mainly bear axial tension or pressure, so that the strength of the material can be fully utilized. When the span is large, the material can be saved compared with the solid web beam, and the weight and weight can be reduced. Increase stiffness. [0003] However, when welding the existing truss, two people are required to fix the two rods separately and then perform welding. This operation is not only inefficient, but the quality of the obtained truss is poor, and the welding cannot be performed well. , Which will affect the quality of the truss, and is not co...
