Description

Technical Field

[0001] This utility model relates to the technical field of bridge construction equipment, and in particular to an adjustable ladder cage wall connection device. Background Technology

[0002] Currently, during bridge construction, the height of the piers necessitates high-altitude work for construction personnel, requiring the use of ladder cages to facilitate their ascent and descent. Existing technology defines a ladder cage as a frame, ladder, handrails, and safety netting. As the pier is raised during construction, the ladder cage also needs to be raised further with the added frame. Once the ladder cage reaches a certain height, guy ropes are used to connect it to pre-embedded components in the pier, securing the cage by pulling it in all directions. In existing technology, vertically extending square tubes are fixedly connected around the frame. The ladder cage is raised by splicing two square tubes together. Connectors are pre-installed on the outside of the square tubes to connect the guy ropes. However, due to human error and other factors, the connectors and pre-embedded components may not be at the same height, causing the ladder cage to tilt due to unbalanced forces, posing a safety hazard. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes an adjustable ladder cage wall-connecting device, which can solve the problem of inconsistent heights of embedded parts and connecting parts between bridge piers and ladder cages.

[0004] An adjustable ladder cage wall-connecting device according to this utility model includes a first connecting member, a second connecting member, and a tensioning mechanism. The first connecting member is used to connect a square tube and includes a first angle steel and a second angle steel. The first angle steel and the second angle steel can be respectively fastened to two opposite sides of the square tube and locked by locking members. Both ends of the first angle steel are provided with first connecting plates, and both ends of the second angle steel are correspondingly provided with second connecting plates. When the first angle steel and the second angle steel are respectively fastened to two opposite sides of the square tube, the first connecting plates are parallel to each other and have a gap. The first connecting plate is provided with a first locking hole, the axis of which is perpendicular to the axis of the square tube. The second connecting plate is correspondingly provided with a second locking hole. The locking member includes a first bolt and a first nut. The first locking hole and the second locking hole are fixedly connected by the first bolt and locked by the first nut. The second connecting member is used to connect embedded parts.

[0033] It is understood that the adjustable ladder cage 100 wall-connecting device provided in this embodiment of the present invention is connected to the two opposite sides of the square tube 110 by the first angle steel 310 and the second angle steel 320 respectively, and is locked and fixed by locking parts. This can more firmly lock the square tube 110 in the first connecting part 300, enhance the stability and tensile strength of the entire structure, help prevent the ladder cage 100 from shifting or loosening during use, and ensure the safety of construction personnel. When it is necessary to adjust the position of the first connector 300 to ensure that the first connector 300 and the embedded part 210 are at the same height, loosen the locking device to separate the first angle steel 310 and the second angle steel 320. Then adjust the connection position of the first angle steel 310 and the second angle steel 320 on the square tube 110 so that the first connector 300 and the embedded part 210 are at the same height. Finally, lock it again with the locking device. The structure is simple and the operation is convenient. It solves the problem of inconsistent height between the embedded part 210 and the connector between the pier 200 and the ladder cage 100. At the same time, when the first connector 300 is removed, it will not cause damage to the ladder cage 100 and the pier 200, so that the first connector 300 can be reused and the usage cost is reduced.
