Abstract
The invention particularly relates to an anti-deformation welding method of a flaky pipe truss. The method is characterized by comprising the following steps of erecting a scaffold; putting a main pipe of the pipe truss onto the scaffold; after the stress release is completed, fixing the main pipe through a positioning device; arching the main pipe in a flame heating mode; sequentially fixing sub pipes in the center position of the pipe truss in the design positions, and fixing the sub pipes with the main pipe through spot welding; welding a welding seam between the main pipe and the sub pipe in the center position of the pipe truss; after the welding seam is cooled, installing the sub pipes at the two sides of the center pipe of the pipe truss, and fixing the sub pipes with the main pipe with te main pipe through spot welding; repeating the former steps; installing all sub pipes onto the main pipe. By using the welding method, arching values are set according to the length of the pipe truss for preventing the deformation in the component hanging and unloading process; the elevation of each fulcrum of the scaffold for placing the pipe truss is the sum of the elevation in the corresponding node and the reverse arching value. Therefore the decoration of the pipe truss during splicing and welding can be further avoided.
Description
Technical field
The present invention relates to building structure construction field, specifically a kind of anti-deforming welding method of lamellar tubular truss.
Background technology
Tube truss structure has that rigidity is big, lightweight, mounting means flexibly, Stability Analysis of Structures, attractive in appearance, mounting means flexibly,
The advantages of be easy to processing and manufacturing and the installation quality improving component, developed in building fields such as China citizen use, commercializations in recent years
Quickly, they are widely used in the roof structure of various buildings, for example: station, airport, venue etc..But there is steel in tubular truss
Pipe specification is many, and angle position is many, the larger phenomenon of welding deformation usually, cause structure suitable in factory's manufacturing process
Profit connects, the problems such as weldquality cannot ensure.
Content of the invention
It is an object of the invention to, the manufacture method that a kind of lamellar tubular truss especially large span lamellar tubular truss is provided,
It is it can be avoided that the problem of the deformation that leads to because of welding in tubular truss manufacturing process and welding precision difference.
In order to achieve the above object, the present invention is achieved in that
A kind of anti-deforming welding method of lamellar tubular truss, including
Step 1, set up moulding bed, the supervisor of tubular truss is placed on moulding bed, after Stress Release finishes, will by positioner
Supervisor fixes；
Step 2, arch camber is carried out to supervisor by flame mode of heating, springing height h is the 1/500 of span, passes through after cooling
Positioner will be responsible for fixation；
Step 3, the secondary Gutron of tubular truss center is crossed positioner be sequentially fixed on design attitude and with supervisor point a solid welding
Fixed；
Weld seam between step 4, the secondary pipe of welding tubular truss center and supervisor；
Step 5, after weld seam cooling after, observe truss bulk deformation degree, errorless after install tubular truss central canal both sides secondary pipe, and
Fix in supervisor's spot welding；
Step 6, both sides time pipe welding simultaneously, welding will stop construction gap after finishing, after weld seam cooling, forms closure local
Stablize unit and can carry out next step；Before welding, secondary pipe is supported reinforcing using angle steel；
Step 7, repetition abovementioned steps, all pipes are arranged on supervisor.
The anti-deforming welding method of described lamellar tubular truss, the preapring for an unfavorable turn of events of lamellar tubular truss according to claim 1
Shape welding method, step 1 arranges moulding bed using falsework, and moulding bed each fulcrum absolute altitude is that at respective nodes, absolute altitude is risen with reverse
The conjunction of arch value height.
The anti-deforming welding method of described lamellar tubular truss, in step 2, carries out arch camber using flame heating, checks
Arch value does not reach and carries out post bake when requiring.
The anti-deforming welding method of described lamellar tubular truss, the positioner in step 1 to step 3 is shearing folder
Tool, this fixture realizes movement and the rotation of itself by electric device.
The anti-deforming welding method of described lamellar tubular truss, in step 6, each node weld after finishing weld seam to be treated cold
But, after finishing, next procedure can be carried out.
The anti-deforming welding method of described lamellar tubular truss, in step 5 and step 6, symmetrical during the sealing of tube of both sides time
Welding, it is to avoid welding deformation.
The present invention adopts above-mentioned welding method, its length according to tubular truss and springing quantum is set, in case lifting component, unloading
It is deformed during car, and be used for preventing moulding bed each fulcrum absolute altitude of tubular truss from being then absolute altitude at respective nodes+reversely arch camber
Value.Tubular truss so can be avoided further to be deformed in splicing welding.
Brief description
Fig. 1 is that tubular truss according to an exemplary embodiment of the present invention manufactures structural representation.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is floating holder figure.
Specific embodiment
Further illustrate 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 lamellar tubular truss, comprises the following steps:
Step 1, set up moulding bed 22, tubular truss supervisor is placed on moulding bed, after Stress Release finishes, by positioner 33
Described supervisor 11 is fixed on above moulding bed.Moulding bed each fulcrum absolute altitude is absolute altitude at respective nodes+reverse springing quantum.
Step 2, arch camber is carried out to supervisor by flame mode of heating, springing height h is the 1/500 of span.After cooling
Fixation will be responsible for by positioner 33.
Step 3, center time pipe 12 is fixed on the relevant position of supervisor by positioner 33, and be responsible for spot welding
Fixing.
Step 4, welding center time pipe 12 and supervisor's weld seam.
