Abstract
A web deformation-preventing structure comprises deformation-preventing plates evenly distributed on a weld joint of a web at equal intervals. The web deformation-preventing structure is simple in structure, simple and convenient to operate, convenient in material taking, low in cost without equipment investment and strong in generality. In addition, requirements for workpieces are low.
Description
Technical field
The utility model relates to a kind of anti-deformation structure, specifically, is a kind of anti-deformation structure of web.
Background technology
During light section steel structure was made, all there was the butt joint of 3-10mm plate in many places such as gutter, H shaped steel flange plate, web, when web thinner, when H shaped steel height is big, because web rigidity is little, a little less than the non-deformability.After the butt welding, because the influence of Thermal Cycle produces the vertical and horizontal welding stress in the weld seam.Under the welding stress effect, the angular deformation and the wave transformation of steel web generation herringbone.The generation of distortion has not only influenced the size correctness of structure, also directly influences the good looking appearance of structure, simultaneously the safety of structure is brought hidden danger.In a single day wave transformation takes place in the butt weld of H shaped steel web, owing to receive the restriction of flange plate, is difficult to correct with suitable way.Therefore, must select suitable anti-deformation measure in advance for use.
The processing method of control welding deformation is complicated to the requirement of equipment now, and equipment drops into high, and the straightening members size receives mechanical dimension's restriction; Versatility is not strong, and higher to workman's specification requirement, the working time is long; Labour intensity is big, and cost is high, and the temperature control requirement of weld seam is high.
The utility model content
The utility model is to the influence of web welding back owing to Thermal Cycle; Produce the vertical and horizontal welding stress in the weld seam and cause distortion, and the processing method of other control welding deformations is complicated to the requirement of equipment, the working time is long; Labour intensity is big; Cost is high, and shortcomings such as the temperature control requirement height of weld seam have designed a kind of anti-deformation structure of novel web.
The utility model web anti-deformation structure is included in the equally distributed anti-deformation plate of equidistance on the weld seam of web.
Preferably, described anti-deformation plate width is 200-250mm, and thickness is more than or equal to 1.5 times of web thinnest part thickness.
The utility model web anti-deformation is simple in structure, and is easy and simple to handle, to workpiece require lowly, draw materials conveniently low equipment input, the highly versatile of need not of cost.
Description of drawings
Accompanying drawing 1 is the front view of the utility model web anti-deformation structure;
Accompanying drawing 2 is the side view of the utility model web anti-deformation structure.
The specific embodiment
The web anti-deformation structure of the utility model shown in Fig. 1 to 2, is included in the equally distributed anti-deformation plate 2 of equidistance on the weld seam of web 1.
Use the welding method of web anti-deformation structure:
1, earlier the groove of butt weld is cleaned out before the butt joint;
Should make non-groove one side to the operator when 2, docking, so as the observation misalignment, spot welding anti-deformation plate;
3, as requested anti-deformation plate symmetric points are welded on the weld seam, anti-deformation plate and web indirect welding, solder joint length 10mm, spacing 100mm, the two ends of anti-deformation plate and each 10mm of weld seam both sides must spot welding.
Should weld the groove side weld earlier when 4, welding, every section fusion length all strides across the anti-deformation plate between two parties.
5, welding conditions determine with thickness of slab; One face down bonding finishes afterwards reverse side again.
6, can earlier the anti-deformation plate be removed before the reverse side welding;
7, after the back chipping, the weld seam welding is finished;
8, polish the spot welding point of anti-deformation plate.
The web anti-deformation structure of the utility model can solve H shaped steel when butt joint, because web height is too high, welding stress makes the web unstability and the distortion that causes.Through the welding bead reverse side of web being increased the steel plate of certain size, simple in structure, the convenient use.Use this method not need assembler or welder's special technical ability, easy master.Steel plate can adopt clout to make, and draws materials conveniently, and cost is low.Need not the additional apparatus input.
Claims (2)
1. a web anti-deformation structure is characterized in that, is included in the equally distributed anti-deformation plate of equidistance on the weld seam of web.
2. web anti-deformation structure according to claim 1 is characterized in that, described anti-deformation plate width is 200-250mm, and thickness is more than or equal to 1.5 times of web thinnest part thickness.
