CONSTRUCTION WITH MEMBRANE-PNEUMATIC COATING Russian patent published in 2021 - IPC E04H15/20 

FIELD: construction industry.

SUBSTANCE: invention relates to ground construction, in particular to the construction of large-span structures with a membrane-pneumatic coating having spans from 60 to 150 meters. The expected result is achieved by the fact that a structure with a membrane-pneumatic coating, rectangular in plan, contains an external support device made in the form of side walls connected to each other by the end wall of the structure, an internal support device including vertical columns connected to each other by a horizontal crossbar located along the structure, and a multi-span prestressed membrane-pneumatic coating consisting of several lens-shaped cavities formed by lower and upper membranes fixed to the external support device. To reduce the deformability and increase the operational reliability of the structure, the external support device is made in the form of two side buildings, each of which includes two flat walls, the upper coating plate and the floor slabs. At the same time, the lower and upper coating membranes above the crossbar of each row of vertical columns are hermetically sealed together along the entire length of the crossbar, providing autonomous tightness and independent operation under power loads of each lenticular cavity of the membrane-pneumatic coating. Inside the structure, the walls of the side buildings at the level of the upper floor are connected to each other by horizontal rods combined with separate vertical columns of the internal support device and located across the structure below the membrane-pneumatic coating. The interior of the structure, located between the coating and the floor of the structure, has an excess air pressure maintained by an air injection machine.

EFFECT: reduction in deformability and an increase in the operational reliability of the structure.
