Climbing frame site management common problems
Release Time:

1, protection is not in place
Segment position, side steel plate protection of the cantilever section at the top of the frame, hard isolation of the bottom of the frame, isolation of the operating layer, etc.
2. Attaching support anchorage is not in place
Improper installation of the double nut of the support screw, fear of concrete contamination, deliberately not exposing the buckle part of the support suspension, unreasonable installation position of the support hole of the support screw, no cracks.
3. The anti-fall device fails
The anti-fall device is offset, the anti-fall teeth are not tightened, and the anti-fall device is seriously polluted.
4, the outer protection height is lower than the operating surface
After the pouring, because the aluminum mold is poured, the k plate is not removed, and the top support cannot fall off, affecting the safety of the frame, and the working surface is higher than the protection surface.
At this time, it is necessary to strengthen the coordination work of the team and optimize the support K plate to avoid the continuous existence of the problem.
5, climbing templates and other materials piled up seriously
Steel wire, aluminum molds, screws and other materials piled on the shelves, may cause high fall or overload.
6. Lifting support anchorage
The strength of the concrete at the anchorage is insufficient when the load of the support is increased, which is easy to produce deformation and crack the structural members. The working load of the raised support is large, and the stress of the anchoring parts such as the balcony side beam is greater than the design requirements, resulting in cracks in the structure. The current construction progress is generally fast, especially in the winter construction, the concrete strength is slow to improve, which needs to pay enough attention.
7, the support fixed
The support table has only one bolt, and the bottom of the support table does not resist the structure, there is a risk of instability of the support table.
8, the device corrosion is serious
Electric hoist, attachment bracket lack of maintenance, serious corrosion.
9, building climbing frame lifting
Due to the lack of attachment support, the upper cantilever is too large, and the main frame is turned out.
The above problems can be found and solved in time through advance management and daily inspection. It is hoped that while working fast, the management of major hazards should be strengthened to prevent quality and safety accidents.
