Project Description
Membrane Structure


    The project is located in Hanoi, Vietnam. A plurality of inverted cone-shaped membrane tops are linked together with an air-core column to collect rainwater in a large area, and the columns are in communication with underground drainage channels. This structure is designed with organized drainage methods, unique shapes and free-form surfaces. Fully consider the reasonable way of modeling and drainage to avoid large deformation of the membrane under the effect of rain.


    This type of styling is suitable for awnings such as sports stands shade, sports plazas, community entrances, commercial streets, and municipal facilities. The shape is simple and generous, with different styles.

Product Installation
Membrane Structure

The production of steel structures shall comply with the relevant provisions of (Steel Structure Engineering Quality Acceptance Specification) GB50205-2001.
The level of welding quality shall be class III. The butt weld shall be a penetration cut weld.
Steel structure and anchorage foundation: The production of steel structural columns meets the requirements of installation accuracy and controls the dimensional error of the connecting pieces. The anchoring foundation requires that the position deviation of adjacent bearings should not exceed 15m.
The gusset plate thickness is -6m, and the weld height is not specified as 6m.
All structural parts that have tapped holes or round holes need to be machined with a smooth, sharp angle.
The end of the tube shall not be exposed, and the thickness of the sealing plate shall be 4m.
Reasonably arrange the installation sequence of steel structure and membrane structure.

Structural Coating
