Anchoring an air Dome to the Ground


Air Dome as a new type of large temporary building solves the needs of large space and environmental protection issues, so it is very popular in sports, environmental protection, industry, and other fields. Its characteristics of quick construction, tight sealing, and inflatable membrane structure have also attracted the attention of many people. Although the material of the Air Dome is the membrane, its formation is not just as simple as blowing up a ball. Because the Air Dome Structure is based on anchoring systems, so we must do the basic work in primary. Firstly, If you want to build a semi-permanent Air Dome with excellent quality you need to have a huge space. The Air Dome building does not have high requirements on the ground. Whether it is land, grass, or mud. After the ground is leveled, the wiring can be laid out according to the design drawings, after confirming the position, you can prepare for excavation. Depending on the pile driving depth of the foundation, different space and size of the Air Dome usually vary. Generally, more larger more deeper than the foundation. We generally use reinforced concrete beams with inverted T-shaped bases. It can effectively ensure the stability and pull-out resistance of the foundation; after finishing the basic excavation, we will pour the foundation cushion. Secondly, we will tie the steel bars in the foundation on the cushion layer in order to make up for the poor tensile and bending resistance of concrete and improve the tensile performance of the foundation. After the steel bars are tied, we still need to embed the expandable bolts, because the Air Dome structure is connected to the foundation through bolts. Finally, we can carry out the construction of basic forms and frames, which can be regarded as molds for cast-in-place concrete,…


How are air domes made?


How to make air-supported structure? In the field of modern architecture, air-supported structure has attracted widespread attention for its safety, economy, comfort and convenience; completely different from traditional structure, it uses flexible membrane materials as the main sheild material, and uses a set of intelligent The electromechanical equipment provides positive air pressure internally to support the entire structure.
