Climbing frame technology introduction and advantages climbing frame is also known as lifting frame, according to its power source can be divided into hydraulic type, electric type, manual type and other main categories
. 
There is only one bolt on the fixed support, and the bottom of the support is not firmly against the structure, so there is a hidden danger of bearing instability
. 
This system makes the scaffold technology completely changed: first, there is no need to turn over the scaffold; second, the disassembly process of the scaffold is eliminated (after the first assembly, it is always used after the construction), and it is not limited by the height of the building, which greatly saves manpower and materials
. 
At this time, it is necessary to strengthen the team coordination and optimize the K-plate at the support to avoid the continuous problems
. 
Because of the use of aluminum formwork, the K-plate can not be removed after the completion of concrete pouring, resulting in no attachment of the top support, which affects the climbing frame lifting and causes the operation surface to be higher than the protection surface

The above problems can be found and resolved in time through prior management and daily inspection
. 
With the advancement of technical progress and standardization, more and more climbing frame system is used in project construction, which brings great benefits to the safety, civilization, progress and cost of construction
. 
When the lifting support is anchored, the concrete strength at the anchorage is insufficient, the deformation is too large, and the structural components are cracked; when the lifting support is working, the load is large, and the structural stress at the anchorage position, such as the abutment side beam, exceeds the design, resulting in structural cracks

The main contents of this book include the overview, basic structure, construction technology, maintenance and safety prevention, common faults and on-site installation of the attached lifting scaffold
. 
The anti falling device fails, the anti falling device deviates, the anti falling teeth are not tightened, and the anti falling device is seriously polluted

We hope that we can pay attention to the control of major hazard sources and prevent the occurrence of quality and safety accidents

At present, the construction progress is generally fast, especially in winter, the concrete strength rises slowly, which needs to be paid enough attention

Most of the sub projects are organized and implemented by professional sub contractors, and the project department is in charge of the sub projects by package in the process of use
.
The lack of the attachment support of the climbing frame caused the upper cantilever to be too large and the main frame to overturn
.
The anchorage of the attached support is not in place, the double nuts of the support screw are not in place, the screw thread is not exposed intentionally due to the fear of concrete contamination; some supports are cantilevered, and the upper inclined rod is not set in time; the setting position of the bolt hole of the support is unreasonable, and the crack phenomenon appears
.
The components are seriously corroded, the electric hoist and the attachment support are lack of maintenance, and the corrosion is serious
.

.
The protection is not in place, 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
.
The height of the outer enclosure is lower than that of the operation surface
.
The compilation of this book is mainly based on the compilation outline of training materials for special construction workers, and refers to the engineering quality and Safety Manual (Trial) issued by the Ministry of housing and urban rural development
.
And from the safety point of view, the traditional scaffold has been greatly improved
.
It is a new scaffold system developed in recent years, which is mainly used in high-rise shear wall buildings
.
The formwork and other materials on the climbing frame are seriously piled up, and the reinforcement, aluminum formwork accessories, screw and other materials are piled up everywhere on the climbing frame, which has the hidden danger of falling objects and overload
.
It can go up or down along buildings

Xiao Bian listed several problems of nonstandard field operation, hoping to attract attention
.
There are many problems, such as the approval of the scheme does not meet the requirements, the lack of process management action, the rough operation on site, and the difficulty in coordination of work types, which bring great risks to the quality and safety of the project
.
If you need more knowledge about tunnel, road and bridge, please pay attention to WeChat official account of “safety in construction of track Luqiao”.
.
It plays a specific guiding role in strengthening the safety production awareness of the scaffolders of the attached lifting scaffold, enhancing the safety production responsibility, and improving the safety technology level of the construction site
