The inflatable membrane is fixed on a third fixing structure on the third supporting member 21 when being pulled to the direction of the point d from the section b-e-d of the path.

The vertical surface or the top surface at the tangent position of the crescent mold and the inner half shell is firmly installed, the curved surface of the inflatable membrane is smooth and straight as much as possible, test inflation is carried out after installation, the molded size is checked, and the next procedure construction can be carried out after the requirement is met.

S42, inflating the inner shell; before inflation, an expansion hook is arranged on the ground of the foundation for fixing the steel wire rope. And in the process of inflation, attention is paid to observe whether the air film has large deformation or not, if so, the air pressure is reduced, a steel wire rope is used for traction adjustment in the direction opposite to the deformation direction, then the pressure is increased to the construction pressure, and the steel pipe is used for supporting and adjusting the verticality of the door frame.

S43: and (4) spraying polyurethane on the inner side of the inner shell, and constructing according to the existing disclosed process.

S44: and (5) constructing a concrete structure layer on the inner side of the inner shell according to the existing open process.

S5: opening the door opening and decorating construction.

The door opening is opened, is decorated the construction, wherein: the construction process of opening the door opening and decorating can be carried out according to the prior published process.

By adopting the construction method, the steel skeleton supporting structure consistent with the structural design shape is added in the wall body where the inflatable membrane structure is not easy to shape, the ox horn-shaped steel skeleton supporting structure is added in the shell wall body in the crescent long and narrow area, the inflatable membrane and the supporting structure, the rope at the root of the inflatable membrane and the embedded part of the annular wall (base) are completely anchored and then the inflatable membrane is inflated, the deformation of the inflatable membrane during inflation is limited, under the condition of meeting the requirements of the design shape, the size and the function of the inflatable membrane are unchanged, the construction quality and the appearance effect are ensured by optimizing the structural design method, and the construction progress is accelerated. The problem of adopt prior art construction, whole spherical shell is in aerifing the local membrane body because of not receiving the space restriction of in-process, causes local casing appearance quality to be difficult for guaranteeing, especially crescent moon molding, crescent moon and the tangent department appearance shaping effect of inner shell can not satisfy the design requirement is avoided.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
