Embodiment 1

[0034] Such as figure 1 and figure 2 Shown, the present invention comprises the following steps:

[0035] (1) The first steel pipe is placed between the two third fixed plates 6 on the second fixed plate 2, and the distance between the two third fixed plates 6 is adjusted through the telescopic third telescopic plate 5, so that the first A steel pipe is fixedly placed between the two third fixed plates 6;

[0036] (2) The second and third steel pipes to be welded are placed between the two fixed plates 11 on the first fixed plate 1, and through the expansion and contraction of the first expansion plate 9 and the second expansion plate 10, the first The two and the third steel pipes are fixedly placed between the two fixed plates 11, so that the second and the third steel pipes are adjusted to the required angles, and the lower ends thereof are in contact with the sides of the first steel pipes;

[0037] (3) By rotating the connecting rod 14, adjust the distance between the...

Embodiment 2

[0043] The truss welding method for simultaneously welding multiple steel pipes with different angles in the present invention includes steel pipes for welding into trusses and a fixing device for fixing the steel pipes, 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 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 expand and contract along the width direction of the first fixed plate 1 on the horizontal plane, and the first telescopic plate 9 and the second telescopic plate 10 are opposite to each other. One end of each is vertically connected with a fixed plate 11 for fixing the steel pipe, t...

Embodiment 3

[0045] On the basis of Embodiment 2, the connecting rod 14 is fixedly fitted 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 upper end of the stabilizing plate 16 is fixedly connected with the rotating rod 15, and when the rotating rod 15 is rotated, the stabilizing plate 16 is driven to rotate; , the lower end of the rotating rod 15 and the connecting rod 14 is fixedly connected to the inner bottom of the second fixed plate 2, and the rotating rod 15 and the connecting rod 14 rotate along its axis on the inner bottom of the second fixed plate 2; the upper end of the rotating rod 15 The distance from the upper end of the second fixing plate 2 is 8cm. The height of the connecting plate 7 is one-sixth of the height of the second fixing plate 2 .

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 consisting of members connected to each other by hinges at both ends. The truss is composed of straight rods and generally has a plane or space structure of triangular units. 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, it can save materials compared with solid web beams, reduce self-weight and Increase stiffness. [0003] However, when the existing trusses are welded, two people are required to fix and connect the two rods respectively, and then weld them. This operation is not only inefficient, but also the quality of the obtained trusses is poor, and it cannot be welded well. , which in turn will affect the quality of the truss, which is not con...
