However, with the advancement of welding methods, when using semi-automatic and automatic welding such as fully automatic hot wire TIG welding, if traditional external counterparts are used for positioning, tack welding is required. When the tack weld is large, root welding is likely to cause incomplete penetration, Poor fusion; the positioning solder joint is too small, and the strength i...

Abstract

The invention relates to a mobile type pipe fixing and welding method for building construction. The method includes the specific steps that two ports of a to-be-welded pipe are subject to butt joint in advance, and the position of the pipe is well adjusted; two fixing rings ate clamped to the two sides of a to-be-welded line of the to-be-welded pipe; three or more sliding fastening parts are placed into sliding grooves of the fixing rings so that the sliding fastening parts can be adjusted to appropriate positions, two tightening bolts on each sliding fastening part are screwed down, and the to-be-welded pipe can be stably fixed; and welding operation is carried out, after welding is completed, positioning connecting bolts are released, and the two fixing rings are taken down from the welded pipe. The mobile type pipe fixing and welding method has the beneficial effects that the fixing device is more flexible in opening alignment and convenient to demount, meanwhile, reducing the labor intensity, and improving the construction efficiency.

[0032] Example 1

[0033] As attached Figure 1-5 As shown, the method of fixing and welding pipelines in building construction of this patent has the following specific steps:

[0034] Step 1: Finish the processing of the various components of the pipeline welding fixture, and the structure of each part is:

[0035] Two fixed rings 1: Its structure includes two symmetrically arranged circular rings and two pin shafts; each fixed ring 1 is composed of two half rings; one of the half rings is provided with connecting pieces 11 on the outer sides of both ends , The connecting piece 11 is provided with a pin hole; both ends of the other half ring are provided with the same pin holes as on the connecting piece 11; one end of the two half rings are respectively connected by a pin, each forming a fixed ring 1; The other end connects the two fixed rings 1 by the positioning connecting bolt 3; the half-ring port of the pin connection is also provided with a gap, so that the two half-rings can be opened and closed around the pin, which is convenient for the fixed ring 1 to be in the pipeline 4 to be welded. The mounting and dismounting of the upper part; the notch is also provided at the two half rings fixed by the positioning connecting bolt 3, which is used for the mounting and dismounting of the sliding fastener 2 and the slider 21;

[0036] Three or more sliding fasteners 2: the structure is that the sliding fastener 2 includes two sliders 21, a connecting rod 22 and two tightening bolts 23, and the two sliders 21 are respectively arranged on the connecting rod 22 At least one of the slider 21 and the connecting rod 22 are movably connected to the connecting rod 22 by a screw 24. The lower inner side of the two sliders 21 is provided with a dovetail structure protrusion; the connecting rod 22 is provided on both sides of the center Two threaded holes, two tightening bolts 23 are installed in the threaded holes;

[0037] The specific structure of the movable connection between the slider 21 and the connecting rod 22 is: the end of the connecting rod 22 and the slider 21 is provided with an internal thread hole, the slider 21 is provided with an internal thread through hole, and the screw 24 passes through the slider 21 The internal threaded through hole and the internal threaded hole at one end of the connecting rod 22 fix the slider 21 on one end of the connecting rod 22;

[0038] The outer round surfaces of the two fixing rings 1 are provided with sliding grooves 12 matching the dovetail structure of the lower inner protrusion of the slider 21, and the sliders 21 at both ends of the sliding fastener 2 are respectively arranged on two In the sliding groove 12 of the fixed ring 1, the entire sliding fastener 2 can move along the circumference of the fixed ring 1 in the sliding groove 12.

[0039] Step 2: Connect the two half rings of each fixed ring 1 with pins respectively.

[0040] Step 3: After supporting the pipe 4 to be welded, connect the two ports of the pipe to complete the welding preparations.

[0041] Step 4: Clamp the two fixing rings 1 on both sides of the welding seam of the pipe 4 to be welded respectively, and rotate and adjust the two fixing rings 1 so that the through holes on the two fixing rings 1 correspond to each other, and pass the positioning connecting bolt 3 through The through holes on the two fixing rings 1 connect the two fixing rings 1 for positioning.

[0042] Step 5: Put three or more sliding fasteners 2 into the sliding groove 12 of the fixed ring 1, and install the sliding fastener 2 on the sliding groove 12 by screws 24. 21, the sliding fasteners 2 can move freely with the sliding groove 12 as a track; after adjusting each sliding fastener 2 to the proper position, tighten the two clamping bolts 23 on each sliding fastener 2 to Fix the pipe 4 to be welded.

[0043] Step 6: Perform welding operation. When welding to a certain sliding fastener 2, only need to loosen the two clamping bolts 23 on the sliding fastener 2 to fine-tune the position of the sliding fastener 2, that is, no It will affect the welding operation, so that the pipeline welding can be directly welded without tack welding.

[0044] Step 7: After the welding is completed, loosen the positioning connecting bolt 3, and remove the two fixing rings 1 from the welded pipe.
