What is the applicable point of parallel structure?

Parallel construction is suitable for projects with short construction period, high resource density and cross operation. The disadvantage is that parallel construction cannot be organized between logically related construction processes.

Parallel construction is to organize several same teams in the same construction process to carry out parallel construction at the same time and in different spaces; Or several buildings are started at the same time and built in parallel.

Parallel construction refers to a construction organization mode in which all construction processes of the engineering object are put into operation at the same time. It also refers to the organizational mode in which several same teams carry out construction in different spaces at the same time.

Pay attention to the following points in building construction:

1, when street passages, site passages, building passages, construction elevators and material hoists are within the falling radius or the swing range of the boom, protective sheds and protective passages must be set.

2, safe passage, protective shed should use steel fasteners scaffolding or other steel structures, it is forbidden to use bamboo, wooden poles to build protective shed.

3. For the safe passage with a width of more than 3.5 m or a height of more than 4 m, the spacing between vertical poles should be encrypted or lattice columns with double vertical poles, section steel and scaffolding pipes should be adopted, and the longitudinal cross bars should be made of section steel or load-bearing scaffolding should be erected.

4. The top floor of the safe passage protective shed is provided with protective railings, with two horizontal bars, with a height of 1.2m and a railing spacing of 40cm.

5. Steel columns should be erected on both sides of the entrance of the safe passage protective shed, and safety warning signs and safety propaganda slogans should be hung at the entrance of the safe passage protective shed. The bottom plate of safety signs is made of PVC board or aluminum-plastic board, and the surface layer is made of outdoor film.
