Description

Technical Field

[0001] The present invention relates to the technical field of steel structure processing, and particularly to a welding device for H-shaped steel for buildings and its usage method. Background Art

[0002] In the prior art, the welding of H-shaped steel varies, such as the welding of the middle flange plate and the web plate in a single H-shaped steel, the welding between the ends of two H-shaped steels, the welding of auxiliary H-shaped steel and main H-shaped steel, etc. After retrieval, it is found that a welding H-shaped steel support reinforcement device is disclosed in a Chinese patent (application number: 202322438006.4), which includes a base. A groove is provided inside the base, and a motor is fixedly connected to one side of the outer wall of the base. The driving shaft of the motor penetrates through the groove and is fixedly connected to a bidirectional threaded rod. Both ends of the bidirectional threaded rod are threadedly connected with clamping plates. A center of the side of the base adjacent to the motor is fixedly connected with an electric push rod, and the telescopic end of the electric push rod penetrates through the base and is fixedly connected with a limiting plate.

[0003] Through the mutual cooperation among the motor, the bidirectional threaded rod, the limiting plate and the clamping plates, the above patent drives the two clamping plates to approach each other through the motor, and combines the electric push rod to drive the limiting plate to jointly clamp the H-shaped steel column to be welded, facilitating the rapid positioning of the H-shaped steel column, enabling the H-shaped steel column and the steel beam to be arranged in a mutually vertical state, and avoiding the need to spend a lot of time for calibration when welding the H-shaped steel beam due to the non-horizontal cut of the H-shaped steel column, thereby improving the welding efficiency.

[0004] As we all know, the size and weight of the main H-shaped steel are generally larger than those of the auxiliary H-shaped steel. When the above patent is used, the main H-shaped steel needs to be erected first before welding the auxiliary H-shaped steel. At the same time, when welding the auxiliary H-shaped steel, workers need to climb onto the auxiliary H-shaped steel to carry out the welding. In summary, all of these will make the welding work very laborious. Meanwhile, when welding the suspended auxiliary H-shaped steel, the high-temperature welding slag splashes everywhere, which may harm the staff. Therefore, it is necessary to improve the above prior art. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a welding device for H-shaped steel for buildings and its usage method, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0007] A welding device for H-shaped steel for buildings includes a welding guiding seat slidably mounted on a horizontally placed main H-shaped steel. An auxiliary H-shaped steel is vertically placed on the main H-shaped steel. Two symmetrically arranged support frames are installed on the top of the welding guiding seat, and the two support frames support on both sides of the auxiliary H-shaped steel.

[0008] Specifically, in the present invention, the welding guide seat includes two semi-circular seats that are joined together. The interior of the semi-circular seat matches the surface of the secondary H-beam, and a guiding structure is provided inside the semi-circular seat.

[0009] To prevent the semi-circular seat from moving horizontally along the flange of the main H-beam, a clamping plate is fixed to the bottom near the edge of the semi-circular seat, and the inner side of the clamping plate is clamped outside the flange of the main H-beam.

[0010] To achieve the collection of welding slag, a collection chamber is opened inside the semi-circular seat, and the collection chambers of the two semi-circular seats are connected.

[0011] Specifically, in the present invention, the guiding structure includes a guiding groove opened at the top of the collection chamber and a welding groove opened at the bottom of the chamber. The width of the guiding groove is greater than the width of the welding groove.

[0012] To support the secondary H-beam, the support frame includes two symmetrically arranged U-shaped rods. The opening of the U-shaped rod is clamped on the flange of the secondary H-beam. The outer rod of the U-shaped rod extends towards the center of the semi-circular seat, and a diagonal brace is fixed to the bottom. The lower end of the diagonal brace abuts against the top of the semi-circular seat. The two opposite diagonal braces in the two support frames are joined together and locked. The lower end of the diagonal brace extends outwards to form a convex plate, and a bolt is threadedly connected between the two convex plates.

[0013] The present invention also discloses a method for using the above-mentioned H-beam welding device for construction, including the following steps:

[0014] Step 1: Vertically place the secondary H-beam on the flange of the main H-beam, and then clamp the two semi-circular seats on both sides of the secondary H-beam.

[0015] Step 2: Slide the entire welding guide seat to drive the secondary H-beam to move along the flange of the main H-beam to the welding position. The two support frames are locked by bolts to position the secondary H-beam.

[0016] Step 3: Move the welding torch along the guiding groove, and through the welding groove, weld the secondary H-beam to the flange of the main H-beam. The collection chamber collects the welding slag.

[0017] Step 4: Unscrew the bolt to disassemble the two semi-circular seats.

[0018] Compared with the prior art, the present invention has the following beneficial effects: The sliding of the welding guide seat along the main H-beam facilitates the secondary H-beam to quickly and stably reach the welding position. The welding guide seat enables the welding torch to move circumferentially around the bottom of the secondary H-beam for welding, thereby making the welding more stable. Moreover, the welding slag generated during welding can be collected through the collection chamber to prevent the welding slag from splashing everywhere. The structure is simple and the practicability is higher. Description of the Drawings

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] As Figures 1-5 shown, the present invention provides a building H-beam welding device, including a welding guide seat slidably mounted on a horizontally placed main H-beam M, with a secondary H-beam N vertically placed on the main H-beam M. Two symmetrically arranged support frames are installed on the top of the welding guide seat, and the two support frames support on both sides of the secondary H-beam N.

[0027] Specifically in the present invention, the welding guide seat includes two mutually joined semi-circular seats 1, the interior of the semi-circular seat 1 is matched with the surface of the secondary H-beam N, and a guiding structure is provided inside the semi-circular seat 1.

[0028] In order to prevent the semi-circular seat 1 from moving horizontally along the flange of the main H-beam M, a clamping plate 2 is fixed at the bottom near the edge of the semi-circular seat 1, and the inner side of the clamping plate 2 is stuck on the outer side of the flange of the main H-beam M.

[0029] To achieve the collection of welding slag, a collection chamber 1-1 is opened inside the semi-circular seat 1, and the collection chambers 1-1 of the two semi-circular seats 1 are connected and communicated.

[0030] Specifically in the present invention, the guiding structure includes a guiding groove 1-2 opened at the top of the collection chamber 1-1 and a welding groove 1-3 opened at the bottom of the chamber. The groove width of the guiding groove 1-2 is greater than the groove width of the welding groove 1-3.

[0031] To achieve the support for the secondary H-shaped steel N, the support frame includes two symmetrically arranged U-shaped rods 3. The openings of the U-shaped rods 3 are clamped on the flange plates of the secondary H-shaped steel N. The outer rods of the U-shaped rods 3 extend towards the center of the semi-circular seat 1, and a diagonal brace 4 is fixed at the bottom. The lower end of the diagonal brace 4 abuts against the top of the semi-circular seat 1. The two opposite diagonal braces 4 in the two support frames are joined and locked together. The lower end of the diagonal brace 4 extends outwards to form a convex plate 5. A bolt is threadedly connected between the two convex plates 5.

[0032] The present invention also discloses a usage method of the above-mentioned H-shaped steel welding device for buildings, including the following steps:

[0033] Step 1: Vertically place the secondary H-shaped steel N on the flange plate of the main H-shaped steel M, and then clamp the two semi-circular seats 1 on both sides of the secondary H-shaped steel N. At this time, the clamping plate 2 is clamped on the flange plate of the main H-shaped steel M, the U-shaped rod 3 is clamped on the flange plate of the secondary H-shaped steel N, and the two opposite diagonal braces 4 in the two support frames are joined together.

[0034] Step 2: Slide the entire welding guide seat. Through the limitation of the clamping plate 2, the welding guide seat drives the secondary H-shaped steel N to move along the flange plate of the main H-shaped steel M to the welding position. The two support frames are locked by bolts to achieve the positioning of the secondary H-shaped steel N.

[0035] Step 3: The welding torch moves along the guiding groove 1-2, and through the welding groove 1-3, the secondary H-shaped steel N is welded to the flange plate of the main H-shaped steel M. The collection chamber 1-1 collects the welding slag.

[0036] Step 4: Unscrew the bolt to disassemble the two semi-circular seats 1.

[0037] Compared with the prior art, the present invention has the following beneficial effects: The sliding of the welding guide seat along the main H-shaped steel M facilitates the secondary H-shaped steel N to quickly and stably reach the welding position. Compared with the prior art where the main H-shaped steel M is made vertical and then the secondary H-shaped steel N is welded, it is more convenient. The welding guide seat can make the welding torch move circumferentially around the bottom of the secondary H-shaped steel N for welding, thereby making the welding more stable. And the welding slag generated during welding can be collected through the collection chamber 1-1 to prevent the welding slag from splashing everywhere. The structure is simple and the practicability is higher.
