Abstract
The utility model provides an H-shaped steel correcting device which is low in cost and simple to operate. The technical scheme is as follows: the H-shaped steel correcting device comprises a fixed clamp and a storage rack, wherein the fixed clamp comprises a vertical steel bar and transverse steel bars which are welded on two ends of the vertical steel bar, and the transverse steel bars on two ends do not stay on the same horizontal plane; the storage rack consists of at least two H-shaped steel or I-shaped steel which is fixed on the ground. By adopting the technical scheme, the H-shaped steel correcting device is simple in structure and easy to produce and operate, and the H-shaped steel can be corrected by adequately utilizing the upward pulling force of a traveling crane and the gravity of the H-shaped steel as well as the locking force of a T-shaped hanger member on the H-shaped steel.
Description
Technical field
The utility model relates to steel construction manufacture field, relates in particular to the rectification to distortion H shaped steel.
Background technology
H shaped steel is a kind of economical section steel, is widely used in the aspects such as industry, building, bridge, oil drilling platform, and steel structure connection generally adopts welding, and generally all adopts full penetration for some important weld seams.During metal solder, in local heat, fusion process, the mother metal temperature of the metal of the thermal treatment zone and periphery differs greatly, and produces the instantaneous stress in welding process.Be cooled to after original temperature, tension district and the mother metal in whole connector area weld seam Ji Jinfeng district reach balance at compression district numerical value, this has just produced the welding residual stress of structure itself, now, and the distortion of weldment structure generation various ways under the effect of welding residual stress.
In order to reach design, code requirement, the welded structural element that welding deformation has occurred must be corrected, and from another one angle, explains, this rectification is in fact all to manage to cause new distortion to compensate or offset the distortion having occurred.In construction is produced, the antidote of the most frequently used postwelding residual deformation can be divided into application of force rectification and add the combination utilization of heat straightening and two kinds of methods.1, application of force orthosis: the application of force is corrected general with jack, spiral assistor, roll-in arbor press or complete on large pressing machine.2, heating orthosis: utilize inhomogeneous heating to make structure obtain reverse distortion and compensate or offset original welding deformation.The heating means of heating orthosis can be divided into point-like heating, wire heating, triangular heat.Add heat straightening and can eliminate a lot of application of forces and correct insurmountable distortion, the rule of grasping the distortion that flame local heat causes is to carry out the key of rectification, determines that flame straightening effect is mainly position and the heating-up temperature of heating.The Welding Structure of mild steel and common alloy adopts the heating-up temperature of 650～8000C conventionally, generally should not exceed 9000C.These antidotes, or complex operation, otherwise cost is higher, and all waste time and energy, be difficult to increase work efficiency.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of H shaped steel apparatus for correcting with low cost, simple to operate.
For solving the problems of the technologies described above, the technical solution of the utility model is: comprise stationary fixture and rack, described stationary fixture comprises a vertical steel bar and the horizontal steel bar that is welded on its two ends, and the horizontal steel bar at two ends is not in same level; Described rack is comprised of at least two H shaped steel or I-steel that are fixed on ground.
Adopt technique scheme, whole apparatus structure is simple, is easy to make and operation, and make full use of row and hang pulling force upwards and the own wt of H shaped steel, and buckle the hang power of stationary fixture to H shaped steel, with regard to realizing, H shaped steel is corrected.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in the figure, H shaped steel apparatus for correcting provided by the utility model comprises stationary fixture 1 and rack 2, and described stationary fixture 1 comprises a vertical steel bar 11 and the horizontal steel bar 12 that is welded on its two ends, and the horizontal steel bar 12 at two ends is not in same level; Described rack 2 is comprised of at least two H shaped steel or I-steel that are fixed on ground.
During work, first with stationary fixture 1, the one or both ends of workpiece H shaped steel 3 are buckled and hung on rack 2, then with the suspension hook 4 that row hangs, catch on the deformation position of workpiece H shaped steel 3, then start to go to hang up and draw.
Claims (1)
