Description

Technical Field

[0001] This utility model relates to building construction, and in particular to a new type of prefabricated stair handrail conversion component. Background Technology

[0002] Construction involves a lot of work at height (such as at the edges of floors, stairwells, elevator shafts, roofs, etc.). Temporary handrails provide physical barriers for workers, reducing the risk of accidental falls. Temporary handrails can also prevent construction materials and tools from falling accidentally, protecting the safety of people and equipment below.

[0003] In existing stair handrail and edge protection systems, steel pipe splicing is usually used for protection during construction. This is a completely different set of handrail protection from the finished handrail after completion. However, in this construction method, the stair handrail and edge protection during construction are all discarded and can only be depreciated as steel scrap, resulting in a large amount of material waste and inconvenience for turnover.

Adjust the length of the telescopic crossbar to adjust the distance between the two telescopic vertical bars. Then, adjust the length of the telescopic vertical bars to adapt to the slope of the stairs.

[0041] During installation, the screw 804 is rotated to move the screw 804 upward, thereby shortening the distance between the clamping plate 803 and the horizontal plate on the clamping frame 801, so that the clamping seat 8 is clamped on the main body of the staircase.

[0042] After installing multiple handrail standard sections in the above manner, fasten the cover 11 to the top of the handrail standard section, and then lock it to the handrail standard section by tightening the bolts.

[0043] This allows for quick connection of standard handrail sections to the main staircase, and then multiple standard handrail sections can be integrated into one unit via the snap-on cover 11, improving the stability of the handrail. At the same time, the length of the telescopic horizontal and vertical bars can be adjusted to accommodate staircases of different sizes, and it is easy to install and disassemble quickly, making it convenient for turnover.
