Ultra-large-span closed stock bin based on independent air rib type membrane structure

Abstract

The invention discloses an ultra-large-span closed stock bin based on an independent air rib type membrane structure. The ultra-large-span closed stock bin comprises independent air rib units, wherein the upper portions of the independent air rib units are covered with tarpaulin, a wind speed sensor is fixedly installed at the top of the tarpaulin, inhaul cables are fixedly connected to the left end and the right end of the tarpaulin, the ends, away from each other, of the two inhaul cables are fixedly connected with the ground, the adjacent independent air rib units are fixedly connected through buckles, and gable walls are arranged at the ends of the independent air rib units. According to the ultra-large-span closed stock bin based on the independent air rib type membrane structure, the stock bin is prevented from being inflated, the coal storage environment is prevented from being affected, and the internal air pressure environment cannot be affected by opening and closing a door; and meanwhile, the stock bin can be increased or decreased in the length direction according to needs, the overall pressure resistance, wind resistance and deformation resistance are improved, the span can be large, maintenance, monitoring, replacement and detachment are convenient, wind and snow can be resisted, and the air pressure of the independent air rib units can be adjusted according to changes of wind and snow loads in the using process.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a super-large-span closed storage bin based on an independent air-finned membrane structure. Background technique [0002] Compared with steel skeleton silos, inflatable silos have outstanding advantages such as energy saving and environmental protection, simple construction, low cost, and large span, and are gradually occupying an increasing market share. Traditional inflatable silos mainly use air bearings The air-supported membrane structure directly uses a single-layer or multi-layer film as the roof and exterior wall, fixes the surrounding edges of the membrane surface, and pressurizes the membrane building interior (generally 300-500Pa) to make the membrane surface bulge to the design. The inflatable building with curved space can basically meet people's needs, but there are still some problems. The specific problems are as follows: [0003] At present, the int...

AI Technical Summary

Problems solved by technology

[0003] At present, the internal inflation environment of most inflatable silos on the market has a certain impact on the coal storage environment, and the opening of the door will affect the internal air pressure environment. A point of damage will affect the airtightness of the overall structure, which cannot well meet the predetermined Forming, and may cause problems such as the overall collapse of the structure due to gravity
