Description

Technical Field

[0001] The utility model relates to the technical field of steel structure building construction, in particular to a working platform for steel structure building construction. Background Art

[0002] Steel structure building is a new type of building system, which breaks through the industry boundaries between real estate, construction and metallurgy, and integrates them into a new industrial system. Compared with traditional concrete buildings, steel structure buildings use steel plates or steel sections instead of reinforced concrete, which has higher strength and better earthquake resistance. And because the components can be factory-made and installed on-site, the construction period is greatly reduced. Since the reusable steel can greatly reduce construction waste and is more environmentally friendly, it is widely adopted by countries around the world and applied in industrial and civil buildings. In the process of steel structure construction, workers are often required to install high steel structures, so it is necessary to use a work platform to lift the workers to a certain height for construction. The existing publication number CN219773526U discloses a work platform for steel structure construction. Through the setting of moving wheels and moving gear sets, it plays a role of easy and convenient movement. When in use, when it needs to be moved, the motor switch is turned on, the lifting motor runs, and the lifting is driven The transmission gear set runs, rotates by meshing with the thread groove, runs downward, the inner shell as a whole moves downward, the moving wheel passes through the square groove to support the working platform, and the moving motor completes forward and backward movement through forward and reverse rotation. After the movement is completed, the lifting motor reverses, the inner shell as a whole rises, and the upper end of the connecting sleeve contacts the inner wall of the upper end of the outer shell to turn off the power, which overcomes the problem that the working platform is fixed in one place and is difficult to move. However, the support of the bottom of the working platform is poor, which will cause the center of gravity of the working platform to be unstable and the stability to be poor during use, and it is easy to cause the working platform to tip over during use, which has a certain adverse effect on actual use, so it needs to be improved.
