Roof maintenance is an important part of maintenance and engineering. In the overall maintenance of the roof, according to the opening of the roof to see, in addition to the first level because of a few years ago to re-repair and save better, the other layers of the template and rafters have appeared in varying degrees, the focus is on 2 to 7 layers.

Frame Scaffolding is a traditional building construction aids, in the cost and duration of the project has a large proportion, we should be highly concerned about and pay attention to the use of scaffolding technology.  

As the pace of urban construction in China is relatively rapid, those buildings are also close to the high level, in recent years, the development of high-rise buildings will be more and more, which will make all the construction technology once again into the new The reform.

These complex combinations of structures combined with each other, stacking high, around the extension, and then build the level of reinforcement with a wall, etc., and gradually constitute a complete frame scaffolding. Thus ensuring that the scaffolding holds a relatively stable structure and full weight bearing capacity.

Especially in the northeastern direction of the three sides of the mold produced the most serious situation.

Frame type scaffolding is also called the frame type steel pipe scaffolding, the frame type frame must first use the basic unit, the main accessories include the frame and the horizontal beam, etc., all the vertical pole of the pole are used to connect the rod and the lock Arm is high, horizontal cross-supporting the use of connecting the frame pole, and in the top of the horizontal plane is used in the buckle scaffolding.
