Description

Technical Field

[0001] This utility model belongs to the field of steel structure installation, and specifically relates to a steel column node welding platform. Background Technology

[0002] In steel structure installation projects, the splicing and installation of steel columns is a crucial step. Especially for large structures, the application of box-type steel columns is becoming increasingly widespread. However, welding operations at steel column joints, particularly on the outer side of the installation, face significant safety and efficiency challenges. Due to limited space for high-altitude work, traditional welding methods often fail to guarantee welder safety and weld quality.

[0003] Currently, the common practice for welding joints in high-altitude steel columns is to pre-erect a scaffolding platform on top of the next steel column section before hoisting it. This practice has several drawbacks:

[0004] Poor safety: Scaffolding platforms themselves pose risks of working at heights and require frequent dismantling and re-erection, increasing safety hazards for workers.

[0005] Inefficiency: The erection and dismantling of scaffolding platforms are time-consuming and labor-intensive, which prolongs the construction period and affects the progress of the project.

[0006] Therefore, we propose a steel column joint welding platform to solve the above problems. Utility Model Content

[0007] Currently, the common practice for welding high-altitude steel column joints is to pre-erect a scaffolding platform on top of the lower steel column before hoisting it. However, erecting scaffolding has problems such as poor safety and low efficiency. This utility model provides a steel column joint welding platform.

[0008] The solution adopted by this utility model to solve its technical problem is: a steel column node welding platform, including a U-shaped frame, anti-tilt rod, two mounting plates and four T-shaped rods. The inner cavity shape of the U-shaped frame is adapted to the outer contour of the steel column, and a wooden board is laid on its top. A guardrail is fixedly installed on the outer edge of the U-shaped frame.

[0009] Two mounting plates are welded and fixed to the inner edge of the U-shaped frame and are located on the front and rear sides of the steel column, respectively. One end of the mounting plate has a through hole, and the two ends of the anti-tilt rod pass through the two through holes, respectively.

[0010] The four T-shaped rods are arranged in pairs on the front and rear sides of the steel column. One end of the T-shaped rod is fixedly installed on the outer side of the steel column, and its top is used to support the U-shaped frame.

[0011] Four hinge seats are welded and fixed to the bottom of the U-shaped frame. The four hinge seats are arranged in pairs on the front and rear sides of the steel column. Diagonal braces are hinged and installed in the hinge seats. The lower end of the diagonal braces is connected to the lower end of the T-shaped rod by bolts.

[0012] Preferably, the anti-roll bar is a double-threaded bar, with connecting nuts threaded to both ends of the double-threaded bar.

[0013] Preferably, the anti-tilt bar is a steel pipe, with reserved holes at both ends of the steel pipe, and T-shaped pins are installed in the reserved holes.

[0014] Preferably, two fixing nuts are fixedly installed on the mounting plate, and an adjusting screw is connected to the internal thread of the fixing nuts. The inner end of the adjusting screw contacts the outer surface of the steel column.

[0015] Preferably, the U-shaped frame includes an inner U-shaped angle steel and an outer U-shaped angle steel, and multiple square tubes are welded and fixed between the inner U-shaped angle steel and the outer U-shaped angle steel.

[0016] Preferably, the diagonal brace is made of steel pipe or square tube.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model pre-fixes four T-shaped rods to the outside of the steel column and suspends the U-shaped frame on top of the four T-shaped rods. The four T-shaped rods support the U-shaped frame. By connecting the diagonal bracing rods to the T-shaped rods, the U-shaped frame is supported at multiple points and in multiple directions, thus constructing a stable and reliable working platform, effectively avoiding the swaying and overturning risks of traditional scaffolding platforms.

[0019] 2. This utility model allows for the disassembly of the anti-tilt bar and the removal of the bolts one by one, separating the diagonal brace from the T-shaped bar. This enables the U-shaped frame and guardrail to be lifted as a whole, completing the rapid disassembly of the platform. The platform can be reused, avoiding cumbersome scaffolding work and significantly improving construction efficiency.

[0020] 3. This utility model uses the anti-tilt rod and four adjusting screws to restrict the U-shaped frame to the outside of the steel column, further enhancing the stability of the platform and ensuring the safety of welders when working at height. Attached Figure Description

[0023] In the diagram: 1 U-shaped frame, 21 hinged seat, 22 diagonal brace, 3 mounting plate, 41 fixing nut, 42 adjusting screw, 51 anti-tilt bar, 52 connecting nut, 6 guardrail, 7 T-shaped bar, 8 steel column, 9 bolt. Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figure 1-2 This utility model provides a technical solution for a steel column joint welding platform:

[0026] Example 1:

[0027] according to Figure 1 and Figure 2 As shown, the structure includes a U-shaped frame 1, anti-tilt bar 51, two mounting plates 3, and four T-shaped bars 7. The U-shaped frame 1 includes an inner U-shaped angle steel and an outer U-shaped angle steel. Multiple square tubes are welded and fixed between the inner and outer U-shaped angle steels. The inner cavity shape of the U-shaped frame 1 is adapted to the outer contour of the steel column 8. A wooden board is laid on its top so that workers can stand on the board to carry out welding operations. A guardrail 6 is fixedly installed on the outer edge of the U-shaped frame 1 to provide workers with a safer working environment.

[0028] Two mounting plates 3 are welded and fixed to the inner edge of the U-shaped frame 1 and are located on the front and rear sides of the steel column 8 respectively. One end of the mounting plate 3 is provided with a through hole, and the two ends of the anti-tilt rod 51 are respectively passed through the front and rear through holes. Under the action of the anti-tilt rod 51, the U-shaped frame 1 is prevented from tilting.

[0029] Two fixing nuts 41 are fixedly installed on the mounting plate 3. The fixing nuts 41 are internally threaded with adjusting screws 42. The inner end of the adjusting screws 42 contacts the outer side of the steel column 8. Through the cooperation of the anti-tilt rod 51 and the four adjusting screws 42, the U-shaped frame 1 is restricted to the outside of the steel column 8, which further enhances the stability of the platform and ensures the safety of welders when working at height.

[0030] Four T-shaped rods 7 are set in pairs on the front and rear sides of the steel column 8. One end of the T-shaped rod 7 is fixedly installed on the outer side of the steel column 8. In this embodiment, the T-shaped rod 7 is fixed by welding. After the steel column 8 is constructed, the T-shaped rod 7 is cut and removed. The top of the T-shaped rod 7 is used to support the U-shaped frame 1.

[0031] Four hinge seats 21 are welded and fixed to the bottom of the U-shaped frame 1. The four hinge seats 21 are set in pairs on the front and rear sides of the steel column 8 respectively. Diagonal braces 22 are installed in the hinge seats 21 by means of pins. The diagonal braces 22 are made of steel pipe or square tube. The lower end of the diagonal brace 22 is connected to the lower end of the T-shaped rod 7 by bolts 9. The multiple diagonal braces 22 provide multi-point and multi-directional support for the U-shaped frame 1, which creates a stable and reliable working platform and effectively avoids the swaying and overturning risks of traditional scaffolding platforms.

[0032] In practical use, the steel column node welding platform of this utility model first welds and fixes four T-shaped rods 7 in pairs to the front and rear sides of the steel column 8, while ensuring that the T-shaped rods 7 are at a suitable height. Then, a crane is used to lift the U-shaped frame 1 and put it on the outside of the steel column 8. The U-shaped frame 1 is slowly lowered so that it falls onto the four T-shaped rods 7.

[0033] The anti-tilt bar 51 is passed through the through holes on the two mounting plates 3, and the adjusting screws 42 are rotated one by one until the inner end of the adjusting screw 42 contacts the outer side of the steel column 8. Then, the lower end of the diagonal brace 22 is connected to the lower end of the T-shaped bar 7 one by one through the bolts 9. After the installation is completed, the worker stands on the wooden board on top of the U-shaped frame 1 to carry out the welding operation.

[0034] Example 2:

[0035] Based on Example 1, the differences are as follows: Figure 2 As shown, the anti-roll bar 51 is a double-threaded bar, and the two ends of the double-threaded bar are respectively threaded with connecting nuts 52.

[0036] Example 3:

[0037] Based on Embodiment 1, the difference is as follows: the anti-tilt bar 51 is a steel pipe, and reserved holes are opened at both ends of the steel pipe, and T-shaped pins are installed in the reserved holes.
