Description
Technical field
The present invention relates to building structure construction field, the anti-deforming welding method of specifically a kind of sheet tubular truss.
Background technology
Tube truss structure have rigidity is big, light-weight, mounting means flexibly, stable structure, beauty, mounting means flexibly,
The advantages that convenient for improving the processing and manufacturing of component and installation quality, developed in recent years in building fields such as China citizen use, commercializations
Quickly, they are widely used in the roof structure of various buildings, such as：Station, airport, venue etc..But there are steel for tubular truss
Pipe specification is more, and angle position is more, the phenomenon that welding deformation is larger usually occurs in factory's manufacturing process, causes structure suitable
The problems such as profit connection, weldquality can not ensure.
Invention content
The object of the present invention is to provide a kind of production method of sheet tubular truss especially large span sheet tubular truss,
It can avoid the problem that deformation and welding precision are poor caused by welding in tubular truss manufacturing process.
In order to achieve the above object, the invention is realized in this way：
A kind of anti-deforming welding method of sheet tubular truss, including
Step 1 sets up moulding bed, and the supervisor of tubular truss is placed on moulding bed, after treating stress release, is filled by positioning
It puts and fixes supervisor；
Step 2 carries out supervisor by flame mode of heating arch camber, and springing height h is the 1/500 of span, after cooling
It will be responsible for and fixed by positioning device；
Secondary pipe at tubular truss center is sequentially fixed at by positioning device on design position and with being responsible for point by step 3
Solid welding is determined；
The weld seam between secondary pipe and supervisor at step 4, welding tubular truss center；
Step 5, after weld seam cooling, observe truss overall deformation degree, it is errorless after installation tubular truss central tube both sides time
Pipe, and fixed in supervisor's spot welding；
Step 6, the welding simultaneously of both sides time pipe, will stop construction gap, after weld seam cooling, be formed and be closed after welding
Local stability unit can carry out in next step；Before welding, reinforcing is supported using angle steel to secondary pipe；
Step 7 repeats abovementioned steps, and all pipes are mounted on supervisor.
The anti-deforming welding method of the sheet tubular truss, sheet tubular truss according to claim 1 are preapred for an unfavorable turn of events
Shape welding method, step 1 set moulding bed using falsework, and each fulcrum absolute altitude of moulding bed is absolute altitude at respective nodes with reversely rising
The conjunction of arch value height.
The anti-deforming welding method of the sheet tubular truss in step 2, is heated using flame and carries out arch camber, checked
Reheating is carried out when arch value does not reach requirement.
The anti-deforming welding method of the sheet tubular truss, the positioning device in step 1 to step 3 are shearing folders
Tool, the fixture realize the movement and rotation of itself by electric device.
The anti-deforming welding method of the sheet tubular truss in step 6, will treat that weld seam is cold after each node weld
But after, next procedure can be carried out.
The anti-deforming welding method of the sheet tubular truss, in step 5 and step 6, when both sides time pipe welding, is symmetrical
Welding avoids welding deformation.
The present invention uses above-mentioned welding method, and springing quantum is set according to the length of tubular truss, to prevent lifting component, is unloaded
It is deformed during vehicle, and it is then absolute altitude at respective nodes+reversed arch camber to be used to prevent each fulcrum absolute altitude of moulding bed of tubular truss
Value.Tubular truss so can further be avoided to be deformed when splicing and welding.
Description of the drawings
Fig. 1 is tubular truss manufacture structure diagram according to an exemplary embodiment of the present invention.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is floating holder figure.
Specific embodiment
It is further illustrated the present invention below by way of specific embodiment.
As shown in Figure 1 and Figure 2, a kind of anti-deforming welding method of sheet tubular truss, includes the following steps：
Step 1 sets up moulding bed 22, and tubular truss supervisor is placed on moulding bed, after treating stress release, is filled by positioning
It puts 33 the supervisor 11 is fixed on above moulding bed.Each fulcrum absolute altitude of moulding bed is absolute altitude+reversed springing quantum at respective nodes.
Step 2 carries out supervisor by flame mode of heating arch camber, and springing height h is the 1/500 of span.After cooling
It will be responsible for and fixed by positioning device 33.
At center pipe 12 is fixed on by positioning device 33 on the corresponding position of supervisor, and with being responsible for spot welding by step 3
It is fixed.
Time pipe 12 and supervisor's weld seam at step 4, welding center.
Step 5, after weld seam cooling, observe truss overall deformation degree, it is errorless after installation center pipe both sides time pipe 13, and in
Supervisor's spot welding is fixed.
Step 6, the welding simultaneously of both sides time pipe 13.Retain enough construction gaps after welding, after weld seam cooling, shape
It can be carried out in next step into local stability unit is closed.Before welding, reinforcing is supported using angle steel 14 to secondary pipe.
Step 7 repeats abovementioned steps, and all pipes are mounted on supervisor.
As shown in figure 3, in above-mentioned steps, positioning device 33 is shearing fixture, which is realized certainly by electric device
The movement and rotation of body.
