Description

Technical Field

[0001] The invention relates to the technical field of welding correction, and in particular to a simple correction device for a welded I-beam. Background Art

[0002] I-beam refers to an iron beam, steel beam or cast steel beam with an I-shaped cross-section. I-beams are usually produced and manufactured by extrusion rolling, casting or welding. Compared with extruded and cast I-beams, welded I-beams are prone to deformation after welding, and it is difficult to ensure the flatness of the I-beam flange.

[0003] At present, the deformation correction method for welded I-beams usually adopts to place a pad under the wing plate and slowly pressurize the wing plate for correction through a hydraulic press. The disadvantage of this correction method is that the I-beam is difficult to clamp and fix. Once the I-beam is not firmly fixed, relative sliding is likely to occur between the I-beam and the pad after the hydraulic press is loaded, making it difficult to ensure the correction effect and the operation is highly dangerous. Summary of the invention

[0004] In view of this, the present invention provides a simple correction device for a welded I-beam, which can solve the problem that the existing correction method is difficult to clamp and fix, and at the same time improve the operational safety of the correction process.

[0005] A simple correction device for a welded I-beam comprises more than two support plates, a connecting plate and a bottom plate;

[0006] The two or more support plates are divided into two groups, and the two groups of support plates are welded on the upper surface of the bottom plate in a left-right symmetrical manner. The adjacent support plates in each group of support plates are parallel to each other and have equal spacing; the spacing between the two groups of support plates is greater than the thickness of the upper web of the I-beam, and at the same time, the space formed between the lower parts of the two groups of support plates can allow the wing plates of the lower half of the I-beam to pass horizontally; the connecting plates are welded on the side surfaces and top surfaces of each group of support plates to fix the same group of support plates into one body, and the connecting plates on the top surface are used to support and cooperate with the wing plates of the upper half of the I-beam.

[0007] Furthermore, the space between the lower parts of the two groups of support plates forms a transition from a conical space to a rectangular space.

[0008] Furthermore, the simple correction device also includes a pad block, which is added under the lower wing plate of the I-beam according to the actual height of the I-beam, and the pad block provides support for the I-beam.

[0009] Furthermore, the thickness of the bottom plate is greater than the thickness of the support plate, and the thickness of the support plate is greater than the thickness of the connecting plate.

[0010] Furthermore, there are two connecting plates welded on the outer side of each group of support plates, and there is one connecting plate welded on the inner side of each group of support plates.

[0011] Beneficial effects:

[0012] 1. The correction device of the present invention is composed of a support plate, a bottom plate and a connecting plate. Two groups of support plates are welded to the upper surface of the bottom plate in a bilaterally symmetrical manner. The connecting plate is welded to the side and top surface of each group of support plates to fix and connect the same group of support plates into one. The I-beam passes through the gap formed between the two groups of support plates, and the wing plate of the upper plate part of the I-beam overlaps the upper surface of the two groups of support plates, thereby forming an overall limit and support for the I-beam, making the assembly between the I-beam and the correction device simple. Since the support structure is composed of multiple support plates, once the hydraulic press is overloaded, the individual support plates will deform to prevent rigid damage, thereby improving the operational safety of the correction process.

[0013] 2. The main support structure of the present invention is composed of more than two support plates, which can greatly reduce the processing and production costs of the correction device and reduce the requirements and losses of processing materials compared to the integrally formed support structure.

[0014] 3. The space formed between the middle and lower parts of the two groups of support plates of the present invention can allow the wing plate of the lower half of the I-beam to pass horizontally. At the same time, the space between the middle and lower parts of the two groups of support plates forms a transition from a conical space to a rectangular space, so that the device can adapt to the correction work of I-beams of various specifications.

[0021] Twenty support plates 1 are divided into two groups, and the two groups of support plates 1 are welded on the upper surface of the bottom plate 2 in a left-right symmetrical manner. Adjacent support plates 1 in each group of support plates are parallel to each other and have equal spacing; the spacing between the two groups of support plates 1 is greater than the thickness of the upper web of the I-beam. At the same time, the space formed between the lower and middle parts (i.e., the cut-off parts) of the two groups of support plates 1 can allow the wing plates of the lower half of the I-beam to pass horizontally; eight connecting plates 3 are divided into two groups and are respectively welded on the side and top surfaces of each group of support plates 1, among which two are welded on the outer side, one is welded on the inner side, and one is welded on the top surface. The connecting plates 3 fix the support plates 1 of the same group into one, and the connecting plates 3 on the top surface are used to support and cooperate with the wing plates of the upper half of the I-beam.

[0022] In this embodiment, the base plate 2, the support plate 1 and the connecting plate 3 are all made of medium carbon steel, the thickness of the base plate 2 is 5 mm, the thickness of the support plate is 3 mm, and the thickness of the connecting plate is 2 mm.

[0023] When performing the calibration work, fix the calibration device on the calibration platform, then insert the I-beam from the end into the gap between the two sets of support plates 1 of the calibration device, add a pad under the lower wing plate of the I-beam according to the actual height of the I-beam, and then apply force to the surface of the upper wing plate of the I-beam through the hydraulic press, and the calibration work can be completed in conjunction with the fire calibration.
