Abstract
The present invention relates to a kind of construction method that correction steel bridge beam and face buckling deformation is completed using gantry cutting machine, it is characterized in that：More mouth grilled guns are installed on gantry cutting machine crossbeam, the floorings for welding completion are placed on gantry cutting machine platform, the spacing of each grilled gun is adjusted according to the spacing of every piece of ribbed stiffener on floorings, every welding bead on floorings is aligned with each grilled gun respectively, light a fire after aligning, start gantry cutting machine to be moved forward or rearward, that is, complete the correction work of floorings.
Description
Technical field
Patent of the present invention is related to a kind of construction party that correction steel bridge beam and face buckling deformation is completed using gantry cutting machine
Method, mainly applies to structure steel fabrication field.
Background technology
Top, bottom in Steel Bridge, web are referred to as floorings, since the area of floorings is larger, in order to increase its intensity
And rigidity, welding ribbed stiffener, and the gap ratio comparatively dense of ribbed stiffener are required on floorings, after the completion of welding, floorings because
Warping phenomenon occurs for welding contraction, occurs such situation in the past, typically using artificial flame straightening, i.e., is baked and robbed with one
Toasted on a welding bead, such construction method, that is, lost labor, and shorten efficiency, cost increase.
The content of the invention
The purpose of patent of the present invention is low in order to solve artificial flame straightening efficiency, and a kind of operation that is of high cost and inventing is simple
Construction method single, efficient, cost is low.
The purpose of the present invention is what is realized in the following ways：
Multiple grilled guns are installed on gantry cutting machine crossbeam, the floorings for welding completion are placed on gantry cutting machine puts down
On platform, the spacing of each grilled gun is adjusted according to the spacing of every piece of ribbed stiffener on floorings, every welding bead on floorings is distinguished
Align with each grilled gun, light a fire after aligning, start gantry cutting machine and be moved forward or rearward, that is, complete rectifying for floorings
Positive work.
It is an advantage of the invention that：Labor strength can effectively be reduced using this construction method, improve production efficiency, reduced
Cost.
Brief description of the drawings
This figure is the usage state diagram of patent of the present invention.
With reference to this figure, patent of the present invention includes gantry cutting machine 1, bakes and rob 2, platform 3, workpiece 4.
Embodiment
The workpiece 4 completed will be welded to be put on platform 3, adjust it is each roasting rob 2 distance, make it is each it is roasting rob 2 distance with
The per pass ribbed stiffener of workpiece 4 apart from equal, to it is each adjust it is roasting rob 2 and light a fire, start gantry cutting machine 1 forward or
Walk backward, that is, complete the correction work of workpiece 4.
Claims (1)
1. the construction method of correction steel bridge beam and face buckling deformation is completed using gantry cutting machine, it is characterized in that：Using gantry
Formula cuts machine frame, and multiple bake is installed on the crossbeam of gantry cutting machine frame and is robbed, and sets Cutting platform, adjusts each roasting
The position robbed is equal with the position of floorings ribbed stiffener.
