Description

Technical Field

[0001] The utility model relates to the technical field of building construction scaffolds, and more specifically, to a building construction scaffold. Background Art

[0002] There are some problems and shortcomings in the existing scaffolding technology for construction. First of all, the existing scaffolding structure is usually simple and requires the use of a variety of support rods for construction. This construction method not only requires a lot of manpower and time, but also requires cumbersome steps to build and adjust the scaffolding when the building is raised, which undoubtedly reduces construction efficiency and increases construction costs.

[0003] Secondly, existing scaffolding equipment is usually fixedly installed, and the equipment position cannot be flexibly adjusted according to actual construction needs. This fixed installation method limits the scope of use of the scaffolding and cannot meet the changes in different construction scenarios and needs, thus affecting the flexibility and efficiency of the construction.

[0004] In addition, although some scaffolding equipment uses hydraulic lifting to achieve the lifting function of the scaffolding, there are certain problems with the guardrail installed on the top of the lifting platform. Some equipment has openings on one side of the guardrail to facilitate workers to get on and off the equipment, but this opening design is insufficient in terms of safety and may increase the safety risks of workers when using the equipment. For those equipment that do not adopt an open design, workers are required to climb over the guardrail to enter the top of the lifting platform, which not only increases the labor intensity of the workers, but also increases the safety hazards during the construction process.

Due to the cooperation between the external threaded sleeve 6 and the internal threaded sleeve 7, the adapter sleeve 8 is limited and locked, thereby effectively preventing the adapter sleeve 8 from moving, thereby ensuring the stability of the connection structure. Then the hydraulic cylinder 17 is turned on, and the hydraulic cylinder 17 drives the lifting platform 2 to rise through the hydraulic rod 18 connected to the output end. At the same time, the lifting platform 2 will drive the telescopic rod 20 to slide out of the telescopic sleeve 19. The setting of the telescopic rod 20 and the telescopic sleeve 19 ensures the stability of the movement of the lifting platform 2. After the lifting platform 2 rises to the specified height, the hydraulic cylinder 17 can be closed.

When the device is moved to the designated location, the screw 26 is rotated by the rotating rod 28. Since the screw 26 and the screw sleeve 27 are movably connected by threads, when the screw 26 rotates, the screw 26 will drive the support block 25 connected to the bottom to spirally descend. When the support block 25 is stably fixed on the ground, stop rotating the rotating rod 28.
