Description

Technical Field

[0001] The present application relates to the technical field of building repair, and more specifically, to a liftable support frame structure for building repair. Background Art

[0002] The support frame for repair is also called scaffolding. The scaffolding is a working platform set up to ensure the smooth progress of each construction process. According to the location of the scaffolding, it can be divided into external scaffolding and internal scaffolding; according to different materials, it can be divided into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding; according to the structural form, it can be divided into vertical pole scaffolding, bridge scaffolding, door scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding. When the building needs to be reinforced and repaired, workers generally use the scaffolding to repair the repair points located at high places. When the existing support frame is used, the height adjustment usually requires people to manually perform additional overlaps on the scaffolding. The overlapping process steps are relatively cumbersome, the operation process is also relatively troublesome, it takes a long time, and it cannot be adjusted steplessly. It is not very convenient for the repair of some building locations, which has brought certain adverse effects to people's use process.

[0003] The document with the prior art publication number CN 220555900 U provides a lifting support frame structure for building repair. The device can automatically adjust the height of the repaired support frame through the worm, turbine, rotating gear, adjusting gear and adjusting movable rod. In this way, people do not need to manually overlap the support frame on the support frame, which is more convenient to use and does not require cumbersome overlapping steps, saving a lot of time, and greatly improving people's efficiency in building repair work. In addition, the adjusting movable rod can steplessly adjust the standing platform. No matter which part of the building is repaired, it can be adjusted to a height suitable for people to work, making people's repair work more convenient. The motor starts, drives the worm in the front to rotate, and the rotation of the worm drives the turbine to rotate. The turbine drives the rotating gear to rotate through the rotating rod, and the rotating gear rotates the adjusting gear. When the adjusting gear rotates, the adjusting movable rod will adjust the angle. When the angle changes, the adjusting movable rod will slide in the middle of the top slide rail through the top movable block and the top slider, and then the height of the standing platform will be changed. In this way, the height of the standing platform can be adjusted, and the operation is convenient and quick.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the device is in use, when the overall height is higher, the support area at the bottom cannot be expanded, the higher the support frame is raised, the worse the overall stability will be, which may easily cause the risk of tipping over.

[0005] In view of this, we propose a liftable support frame structure for building renovation. Utility Model Content
