Project Description
Membrane Structure


  •  

    The project is located in Huanggang Middle School in Conghua District of Guangzhou City. The main body of the stress is based on the steel structure, and the force carrier is the cable structure. The tensioned membrane unit is uniformly loaded on the cable structure to ensure the stability and applicability of the structure. Using professional membrane structure software, the construction and installation simulation analysis calculations were performed at both local and whole levels, including detailed simulation analysis of the distribution and installation of typical structural units; and the overall structure of the shelter was divided into steps according to the construction tension sequence. The simulation of force analysis. The results of force analysis fully show that the structural roof fully utilizes the overall bearing capacity of the structural foundation, maximizes the effectiveness of the material mechanics, and has the characteristics of novel design, unique structure, attractive appearance, and magnificent appearance.

  •  

    This type of styling is suitable for awnings such as sports stands, sunshades, sports plazas, residential entrances, and commercial streets. The styling is simple and generous, and its styles are different.


Design Load & Material Parameter
Membrane Structure


  Design Load
  

Live Load: 0.30kn/m2;
Basic Snow Pressure: 0.30kn/m2;
Lifespan: 15 years.
Basic Air Pressure: 0.40 kn/m2;
Pre-tension of the Film Warp/weft=2.0/2.0 kn/m.


Material Parameter

 ◪ 1.The steel pipes used are all hot-pressed seamless steel pipes, all of which are made of Q235 and conform to GB700-88.

 ◪2.The joint between the pipe and the pipe and the connection between the pipe and the connector are either butt welds or full circumferential fillet welds.

  3.All butt welds must be cut-through welds. These welds are graded three.

  4.Welds are fillet welds, with solder fillets of not less than 4mm and all exposed seams have sealing plates.

  5.Bolts are galvanized ordinary large hex head bolts, in line with GB5780-86; nuts in line with GB41-86.

  6.Manual welding using E43xx electrode.

  7.The film is made of white PVDF film.

 8.The material of the steel wire rope conforms to the universal wire rope standard "GB/T8918-1996". This project adopts a ramie wire rope with a nominal tensile strength of 1570 and the surface is galvanized.

Product Installation
Membrane Structure


                           
1
Installation-1
Appearance inspections are performed on all weld locations. The visual inspection level is Class B.
                           
2
Installation-2
Rust removal is applied at the surface of all components and the rating is St3.
                           
3
Installation-3
All steel components are treated with sharp corners, burrs and flashes. After the weld is welded, the slag and spatter are removed.
                           
4
Installation-4
The ultra-long steel structural parts must be properly segmented at the factory during processing, transported to the site for assembly and welding, and required to be able to ensure that the strength of the assembled weld is stronger than the original steel components.
                           
5
Installation-5
Before the steel structure is installed and installed, it is necessary to check and measure the precision of the buried parts in advance.
                           
6
Installation-6
Arrange the installation sequence of the membrane structure of the steel structure rationally.
