The project department takes the responsibility of contracting instead of management in the process of use.
Thank you..
The subdivisional works are mostly organized and implemented by professional subcontractors.
With the progress of technology and standardization, more and more climbing frame systems are used in project construction, which brings great benefits to the safety, civilization, progress and cost of construction.

The components are seriously rusted.
Xiao Bian listed several problems of non-standard field operations, hoping to draw attention to them.
6 Anchorage of lifting support When the lifting support is stressed, the concrete strength at the anchorage is insufficient, the deformation is too large, and the structural members are cracked; When the lifting support works, the load is large, and the stress of the structure at the anchorage position, such as the side beam of the sun deck, exceeds the design, resulting in cracks in the structure.
3 The protection is not in place at the partition position, the lateral steel plate protection of the cantilever section at the top of the frame, the hard isolation at the bottom of the frame, and the isolation of the operation layer are not in place.
There are generally problems such as unqualified scheme approval, lack of process management actions, rough on-site operations, and difficult coordination of types of work, which bring greater risks to the quality and safety of the project.
There are hidden dangers such as falling objects from high altitude and overloading.
There is only one bolt for fixing the support, and the bottom of the support is not firmly connected with the structure, which may lead to instability of the support.
It has great development advantages in high-rise buildings.
1 The height of the outer enclosure is lower than that of the operation surface.
It is a new scaffold system developed in recent years, mainly used in high-rise shear wall buildings.
5 The fall protector fails, the fall protector deviates, the fall protector teeth are not tightened, and the fall protector is seriously polluted.
According to its power source, it can be divided into hydraulic type, electric type, manual type, etc.
The above problems can be found and solved in a timely manner through prior management and daily inspection.
2 Materials such as formwork on the climbing frame are piled up seriously.
The anchorage of the attached support is not in place.

It can climb or descend along the building.
We hope that everyone can pay attention to the control of major hazard sources while doing a lot of work quickly, and eliminate quality and safety accidents.
The concrete strength rises slowly, which needs to be paid enough attention.
At this time, it is necessary to strengthen the team coordination and optimize the K plate at the support to avoid the problem.
Brief introduction and advantages of climbing frame technology Climbing frame is also called lifting frame.
This system makes the scaffold technology completely changed: First, it is not necessary to turn over the scaffold; The second is to eliminate the disassembly and assembly process of the scaffold (it is always used after the first assembly), and it is not limited by the height of the building, which greatly saves manpower and materials.

How can we do safety supervision on earth? Statement: All materials in this text are from the network.
Materials such as steel bars, aluminum formwork components and screws are piled up on the climbing frame everywhere.
[Overall sketch map of climbing frame] Source: more highlights from the safety officer: the construction is not smooth! Scaffold accident again, 3 dead and 2 injured! Don’t underestimate: the safe distance of operation is very important, and ignoring it may kill people! It’s so common for security officers to leave! Don’t make them sweat and cry…
The electric hoist and the attachment support are lack of maintenance and seriously rusted.
In addition, the traditional scaffold has been greatly improved in terms of safety.
Since January, these new safety regulations and standards have been implemented! The safety officer should pay attention to these new changes…

3 dead and 3 injured, checked 6 times! No hidden danger is the biggest hidden danger! tired Safety management is in chaos.
At present, the construction progress is generally fast, especially in winter.
The double nuts of the support screws are not in place, and the threads are not exposed intentionally because of the fear that the concrete will pollute the threads; Some bearings are cantilevered, and the up inclined rod is not set in time; The bolt hole of the support is set at an unreasonable position and cracks occur.
Because the aluminum mold is used, the K plate cannot be removed after the completion of the concrete pouring, resulting in no attachment of the top support, which affects the lifting of the climbing frame and causes the operation surface to be higher than the protection.
The lack of attached support for climbing frame lifting leads to the overlarge upper cantilever and the main frame overturning.
