Description

Technical Field

[0001] The utility model relates to the technical field of H-shaped steel correction, in particular to an H-shaped steel structure correction device. Background Art

[0002] In the prior art, after H-beam welding is completed, the two flange plates of the H-beam may be uneven due to angular deformation caused by the welding of the main weld and the inner partition weld, which requires correction.

[0003] The existing correction method is as follows: the staff uses a slate pencil or ink fountain to mark the position range of linear heating, and then uses a handheld flame spray gun to perform longitudinal linear heating on the steel surface within the marked range. The heating temperature is controlled below 650°C, and the heating range does not exceed the range corresponding to the two weld legs. Repeated heating at the same position is strictly prohibited. When the H-shaped steel softens, use tools such as pliers to move the flange plate back to a horizontal position.

[0004] However, the above-mentioned method of heating by moving the flame spray gun with the worker's hand is prone to skewness and is not stable enough because the worker's hand may shake, which will cause the heating to deviate and result in poor quality of the flange plate. Therefore, improvement is needed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides an H-shaped steel structure correction device, which solves the problems mentioned in the background technology.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] An H-shaped steel structure correction device includes a gun plate, which includes mounting plates at both ends, with multiple detachable branch plates connected between the two mounting plates, and a gun groove running through the two mounting plates and each branch plate. Two support feet with adjustable spacing are installed on the gun plate, and a long strip gun groove is opened on the top of the gun plate for sliding a flame spray gun.

[0008] In order to fix the mounting plate and the branch plate, ear plates are fixed to the bottom where the mounting plate contacts the branch plate and the bottoms at both ends of each branch plate, and the two ear plates in contact with each other are connected by bolts.

[0009] Specifically in the present invention, the supporting foot includes a right-angle plate, a sliding frame is fixed to the upper end of the vertical plate of the right-angle plate, the frame opening height of the sliding frame is greater than the thickness of the gun plate, and the gun plate is mounted in two sliding frames.

[0010] In order to fix the entire device on the H-shaped steel, the right-angle plate is a magnet plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the mounting plate can be mounted on the H-shaped steel through the support legs, and the flame spray gun can move stably and linearly along the gun plate through the gun slot, so that the H-shaped steel will not be skewed when softening, and it is more stable.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] like Figure 1 As shown, the utility model provides an H-shaped steel structure correction device, including a gun plate. The material of the gun plate can be a high-temperature resistant material, and the distance between the gun plate and the H-shaped steel M can be long enough when it is erected, so that the flame spray gun will not soften the gun plate when it is working. The gun plate includes mounting plates 1 at both ends, and a plurality of detachable branch plates 2 are connected between the two mounting plates 1. A gun groove 3 runs through the two mounting plates 1 and each branch plate 2. Two support feet with adjustable spacing are installed on the gun plate. A long strip-shaped gun groove 3 is provided on the top of the gun plate for sliding the flame spray gun. The spray gun is not drawn in the utility model.

[0020] like Figure 2-3 As shown, in order to achieve the fixation of the mounting plate 1 and the branch plate 2, ear plates 4 are fixed to the bottom where the mounting plate 1 contacts the branch plate 2 and the bottoms at both ends of each branch plate 2, and the two ear plates 4 in contact with each other are connected by bolts.

[0021] like Figure 2 As shown, in the present invention, the supporting foot includes a right-angle plate 5, and a sliding frame 6 is fixed to the upper end of the vertical plate of the right-angle plate 5. The frame height of the sliding frame 6 is greater than the thickness of the gun plate, and the gun plate is mounted in the two sliding frames 6.

[0022] like Figure 3 As shown, in order to fix the entire device on the H-shaped steel M, the right-angle plate 5 is a magnet plate.

[0023] like Figure 4-5 As shown, the working principle of the present invention is described in detail below: according to the length of the H-shaped steel M, the number of branch plates 2 to be used is determined, and the branch plates 2 are fixed to each other through the ear plates 4 and bolts, and then the branch plates 2 are fixed to the mounting plate 1, so that the length of the entire gun plate is slightly larger than the length of the H-shaped steel M, and then the gun plate is erected above the H-shaped steel M, and the slide frame 6 is pushed to slide along the gun plate until the two right-angle plates 5 are attracted to the two ends of the H-shaped steel M. Then the staff can hold the flame spray gun and insert the nozzle into the gun groove 3 to slide the flame spray gun along the gun groove 3, so that the flame spray gun can be kept moving in a straight line. After the flame spray gun softens the H-shaped steel M, the two flange plates of the H-shaped steel M can be leveled using other tools, such as pliers.

[0024] Finally, the most important contribution of the present invention is that the mounting plate 1 can be mounted on the H-shaped steel M through the support legs, and the flame spray gun can move stably and linearly along the gun plate through the gun slot 3, so that the H-shaped steel M will not be skewed when softening, and it is more stable.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
