Description
Technical Field
[0001] This utility model belongs to the field of building ladder cage technology, and specifically relates to a ring-shaped ladder cage installation device. Background Technology
[0002] Traditional ladder cage installation methods rely heavily on on-site welding and bolt connections, which result in problems such as long installation cycles, high risks of working at heights, and serious material waste.
[0003] A search revealed that Chinese Patent Publication No. CN216474569U, authorized on May 10, 2022, discloses a combined ladder cage structure for pier casting. The longitudinal ladder cage beam frame consists of a standard ladder cage and a semi-frame ladder cage; the stepped ladder cage beam frame consists of a semi-frame ladder cage and a staircase ladder cage; the transverse ladder cage beam frames are arranged in pairs, with the longitudinal ladder cage beam frame connected to the left side of the middle of the two transverse ladder cage beam frames, and the stepped ladder cage beam frame connected to the right side of the middle of the two transverse ladder cage beam frames. Patterned steel treads are connected to the upper surfaces of the transverse, longitudinal, and stepped ladder cage beam frames; the two sets of transverse and longitudinal ladder cage beam frames form a U-shaped corridor passage. This design allows for free adjustment of the ladder cage structure according to the size of the cast pier, enabling the ladder cage to wrap around the outside of the cast pier, providing assurance for subsequent pier casting construction and pier inspection, and offering high safety.
[0004] However, the equipment still has the following drawbacks: although it can provide a guarantee for the subsequent pier construction and pier inspection, the combination of the ladder cages and the connection and fixation between them by connecting bolts make the ladder cage structure dependent on complex construction operations, which are often time-consuming and labor-intensive. Moreover, the constructed structure is not effective in resisting the impact of wind loads on the ladder cage. Utility Model Content
