Description

Technical Field

[0001] The invention relates to the technical field of engineering machinery, in particular to a welded H-shaped steel orthopedic device and a use method thereof. Background Art

[0002] H-shaped steel has become the main structural model of steel structure due to its superior structural type and good mechanical properties. H-shaped steel can be divided into two types: hot-rolled H-shaped steel and welded H-shaped steel. The former is widely used in industrial and civil buildings, while the latter is only used in some industrial buildings where hot-rolled H-shaped steel is inconvenient to use. H-shaped steel has a simple structure, strong bending resistance, and low cost. It has strong bending resistance in all directions. The heat input of welded H-shaped steel is too large during the welding process, which is prone to deformation such as upward deflection and lateral bending, resulting in the scrapping of part of the H-shaped steel, resulting in waste. Therefore, it is necessary to solve the deformation problem of H-shaped steel after welding in the prior art, and provide a correction device for solving the upward deflection and lateral bending of welded H-shaped steel. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a welding H-beam correction device with simple structure and good effect and a method of use.

[0004] The present invention is implemented with the following technical scheme: a welded H-beam orthopedic device, comprising a platform, support rods are symmetrically arranged on the platform, a pressure rod and a gear rod are arranged between the support rods on the same side, the pressure rod is located below the gear rod, and a plurality of limiting holes for installing the pressure rod and the gear rod are arranged on the support rod, an H-beam is placed between the pressure rod and the gear rod, the deformed convex side of the H-beam faces downward, a jack is arranged on the platform, and the jack is placed at the deformed part of the H-beam.

[0005] Furthermore, a support rod is respectively provided at both ends of the platform.

[0006] At least two support rods are arranged on the same side.

[0007] The two ends of the H-shaped steel are fixed by a pressure rod and a stop rod, and the lower end of the H-shaped steel is supported by a jack.

[0008] The limiting hole at the lowermost end of the support rod is used for installing the shift rod, and the multiple limiting holes above the support rod are used to adjust the installation position of the pressure rod to adapt to different sizes of H-shaped steel.

[0009] When correcting the side curved surface of the H-shaped steel, a pad is provided on the jack, and the width of the pad is greater than the width of the H-shaped steel.

[0010] A method for using a welded H-beam orthopedic device includes two cases of upward bending deformation and lateral bending deformation, as follows: When the H-shaped steel is deformed upward, first pull out the pressure rod, then place the H-shaped steel to be corrected on the stop rod, with the upper deflection surface of the H-shaped steel against the stop rod. After the H-shaped steel is placed, insert the pressure rod, place a jack under the upper deflection surface, and adjust the jack to lift the upper deflection surface until the upper deflection surface is level with both ends. When the H-shaped steel is deformed by lateral bending, first pull out the pressure rod, then place the H-shaped steel to be corrected on the stop rod, and place the lateral bending surface on the stop rod. After the H-shaped steel is placed, insert the pressure rod, place a pad on the jack, and adjust the jack to lift the lateral bending surface until the lateral bending surface is level with both ends.

[0011] At least one jack is arranged below the deformation location, and the jack is arranged in the area with the largest deformation.

[0012] The present invention has the following advantages: the welded H-shaped steel correction device and the use method of the present invention, by fixing the two ends with smaller deformation, utilizes the combination between the support rod and the gear rod pressure rod, and cooperates with a jack to form a set of correction devices. The device has a simple structure, is flexible and convenient, and has a low manufacturing cost. Different limit holes can be used to achieve correction for H-shaped steels of different models and specifications, and can achieve correction of two deformation forms: upward deflection and lateral bending.

[0020] like Figures 1 to 5A welded H-beam orthopedic device shown includes a platform 1, on which support rods 3 are symmetrically arranged, and between the support rods 3 on the same side, a pressure rod 4 and a stop rod 5 are arranged, the pressure rod 4 is located below the stop rod 5, and the support rod 3 is provided with a plurality of limiting holes 7 for installing the pressure rod 4 and the stop rod 5, an H-beam is placed between the pressure rod 4 and the stop rod 5, and the deformed convex side of the H-beam faces downward, and a jack 2 is arranged on the platform 1, and the jack 2 is placed at the deformed part of the H-beam. The two ends of the H-beam are fixed by the pressure rod 4 and the stop rod 5, and the lower end of the H-beam is supported by the jack 2. The welded H-beam orthopedic device of the present invention is provided with a support rod group on a platform, and the number of the support rod groups is at least two groups, which are respectively arranged at the two ends above the platform, wherein the number of the support rods in the support rod group is at least two, and a pressure rod and a stop rod are connected between the two support rods, and each support rod is provided with a plurality of limiting holes, and the pressure rod and the stop rod are fixed on the limiting holes at different positions to achieve height adjustment, and the H-beam is fixed between the pressure rod and the stop rod. After the H-beam is placed on the platform, the two ends are pressed and fixed by the pressure rod and the stop rod, and another group of support rod groups can be set in the middle of the H-beam to provide better support for the H-beam, or it can be not set, so that most of the area of ​​the H-beam can be exposed, providing operating space for correcting deformation; in addition, a plurality of jacks are provided on the platform, and the jacks are set below the position where the H-beam is deformed, for correcting deformation.

[0021] like Figure 1 to Figure 2 In the welded H-beam orthopedic device shown, a support rod 3 is provided at each end of the platform 1. At least two support rods 3 are provided on the same side.

In addition, the width of the pad is greater than the distance between the two steel plates, ensuring the effective contact between the two steel plates and the pad, which is convenient for the two steel plates to be subjected to force in the same plane during correction.
