When in use, the provided collection box is convenient for collecting impurities scraped off by the scraper to prevent the impurities from falling on the surface of the steel structure again.

[0004] Although the above-mentioned technical solution of the existing steel bracket assembly can realize the application of the bracket, the connection part thereof is mainly assembled by bolt assemblies, and the structural stability needs to be further strengthened. If welding is used to realize the connection and assembly of the steel structure, the above-mentioned laser welding device of a high-strength steel structure assembly can be used for welding and fixing the connection part of the steel structure, but the welds between the various parts of the steel structure are mostly formed by adding reinforcing ribs to improve the structural strength, and the reinforcing ribs are mostly welded directly relative to the steel structure, which will inevitably cause the effective welding position to be too narrow, and the structural strength of a single reinforcing rib needs to be further strengthened. The addition of multiple structural reinforcing ribs will also cause too many welds, reducing production efficiency. Summary of the Invention

[0010] Preferably, a welded transverse groove is provided between the first horizontal connector and the second horizontal connector, and a welded vertical groove is provided between the first vertical connector and the second vertical connector.

[0011] Preferably, both the transverse raised ridge and the vertical raised ridge are provided with a central slot, and the two central slots provide sufficient storage space for the welding ridge in the horizontal welding groove and the welding ridge in the vertical welding groove, respectively.

[0012] Preferably, a clearance fit of no more than 5 mm is adopted between the outer horizontal clamping mouth and the horizontal steel frame, between the outer vertical clamping mouth and the vertical steel frame, between the inner horizontal clamping mouth and the horizontal raised ridge, and between the inner vertical clamping mouth and the vertical raised ridge.

[0013] Preferably, the transverse raised ridges and the vertical raised ridges are integrated with the structural reinforcement frame, and the transverse raised ridges and the vertical raised ridges are symmetrically arranged with respect to the structural reinforcement frame.

[0014] Preferably, the first horizontal connecting member, the second horizontal connecting member, the first vertical connecting member and the second vertical connecting member are all provided with a plurality of secondary reinforcing ribs.

[0015] A laser welding process for high-strength steel structural components comprises the following steps:

[0016] S1. During use, first align the horizontal and vertical steel frames relative to each other, then place the first and second horizontal connectors relative to the horizontal frame, and use a laser to complete the relative welding connection between the first and second horizontal connectors. Ensure that after the first and second horizontal connectors are relatively welded, the overall structure can be adjusted left and right relative to the horizontal frame. Then, place the first and second vertical connectors relative to the vertical frame, and use a laser to complete the relative welding connection between the first and second vertical connectors. Ensure that after the first and second vertical connectors are relatively welded, the overall structure can be adjusted up and down relative to the vertical frame.

[0017] S2. Then, a structural reinforcement frame having an appropriate angle with respect to the angle between the horizontal steel frame and the vertical steel frame is selected, and the relative position of the structural reinforcement frame is adjusted relative to the overall structure of the first horizontal connector and the second horizontal connector so that the structural reinforcement frame can be inserted into the inner horizontal holding opening. Then, the overall structure of the first horizontal connector and the second horizontal connector is adjusted relative to the horizontal steel frame, and the overall structure of the first vertical connector and the second vertical connector is adjusted relative to the vertical steel frame so as to adjust the relative position of the overall structure of the first vertical connector and the second vertical connector and the structural reinforcement frame, and finally, the structural reinforcement frame can be inserted into the inner vertical holding opening.

[0018] S3. Maintaining the relative position of the first horizontal connector relative to the horizontal steel frame, laser irradiation is performed on the portion of the horizontal steel frame exposed from the horizontal outer welding operation notch to cause a certain amount of settlement due to the increase in temperature, so that the first horizontal connector can be confined to the horizontal steel frame. Similarly, heating is performed on the portion of the horizontal steel frame exposed from the horizontal outer welding operation notch on the second horizontal connector, heating is performed on the portion of the vertical steel frame exposed from the vertical outer welding operation notch on the first vertical connector, and heating is performed on the portion of the vertical steel frame exposed from the vertical outer welding operation notch on the second vertical connector.

Then, heating the portion of the horizontal raised ridge exposed from the horizontal inner welding notch on the first horizontal connector, heating the portion of the horizontal raised ridge exposed from the horizontal inner welding notch on the second horizontal connector, heating the portion of the vertical raised ridge exposed from the vertical inner welding notch on the first vertical connector, and heating the portion of the vertical raised ridge exposed from the vertical inner welding notch on the second vertical connector;

[0020] S5. After the structural reinforcement frame achieves structural stability relative to the horizontal steel frame and the vertical steel frame, further welding operations are performed on the overlap of the first horizontal connector and the horizontal steel frame, the overlap of the second horizontal connector and the horizontal steel frame, the overlap of the first vertical connector and the vertical steel frame, the overlap of the second vertical connector and the vertical steel frame, the overlap of the first horizontal connector and the structural reinforcement frame, the overlap of the second horizontal connector and the structural reinforcement frame, the overlap of the first vertical connector and the structural reinforcement frame, and the overlap of the second vertical connector and the structural reinforcement frame.

[0021] Compared with the prior art, the present invention provides a high-strength steel structure component and laser welding process, which has the following beneficial effects:

[0022] (1) In the present invention, the assembly connection between the supporting horizontal steel frame and the vertical steel frame forms a structural reinforcement through the design of the structural reinforcement component. The design in which the weld seam does not directly participate in the structural definition between the horizontal steel frame and the vertical steel frame further improves the structural strength between the horizontal steel frame and the vertical steel frame. The connection is mainly achieved by the materials and structures of the structural reinforcement frame, the horizontal steel frame and the vertical steel frame, thereby reducing the problem of welding fusion at the overlap between the two materials.

[0023] (2) In the present invention, a laser welding process for high-strength steel structural components is formed to realize the welding operation of the structural reinforcement components themselves and relative to the horizontal steel frame and the vertical steel frame, thereby reducing the use of third-class welding materials and ensuring the connection reliability among the structural reinforcement frame, the horizontal steel frame and the vertical steel frame.
