Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

The utility model provides a high-strength plate and air film structure complex, which comprises a film material 1 and a plate material 3,

the lower surface of the plate 3 is provided with a membrane material 1, the membrane material 1 between the plates 3 is pressed by a pressing plate 4 and connected by a rivet 2, a cavity between the membrane material 1 and the plate 3 is filled with high-pressure gas 5, the membrane material 1 is provided with a high-pressure air pump 7 and an inflation check valve 6, the high-pressure gas 5 is injected into the cavity by the high-pressure air pump 7 and the inflation check valve 6 is arranged to prevent the gas from escaping,

the pressure difference between the air pressure in the cavity and the external air pressure is 1-3 atmospheric pressures.

The plate 3 is a wood plate, a steel plate or a plastic plate.

The membrane material 1 comprises an upper membrane and a lower membrane, wherein a grid cloth is arranged between the upper membrane and the lower membrane, and the grid cloth is made of terylene or nylon.

The net cloth is net cloth woven by high-tensile-resistance fiber yarns, the net cloth is made of polyester and nylon according to materials, and EVA (ethylene vinyl acetate) sandwiched net cloth, namely the film material 1, is prepared by heating, extruding and compounding the net cloth with the upper film and the lower film of EVA films.

The utility model converts the point stress and deformation of the plate into the surface stress of the film material instantly through the high-pressure gas in the film material, thereby greatly increasing the pressure resistance and deformation resistance of the plate structure.

The utility model fixes the membrane material on the side surface of the plate by using the sealant, the pressing plate and the rivet, and simultaneously prevents air leakage. A special check valve is used for inflating, so that the air pressure in the film reaches about 1-3 atmospheric pressure difference between the inside and the outside, and the effect of strengthening the strength of the plate can be achieved; the material of the membrane material and the difference value of the internal and external air pressures of the membrane can be selected according to the design load requirement.

The area of the plate is less than or equal to one third of the area of the membrane material, and the excessive large area and the insufficient small area are not beneficial to the transmission of high-pressure gas force.

The utility model must use the automatic linkage equipment of inflation to compensate the air pressure loss in the air film at any time.

When the cross beam is erected, only the plate is used as the cross beam, and the lower supporting upright columns are required to be added to ensure that the plate has certain compressive resistance; and the template, the net clamping film, the universal glue and the steel bar are used for pressing, the membrane is inflated to expand, the point stress of the plate can be decomposed into uniform stress of the membrane in all directions, and the compressive resistance of the plate can be greatly increased. For another example, when a large-span arched shed is constructed, common steel structures are used, and when the span reaches a certain value (for example, 8 meters), the middle part of the shed must be supported by the upright posts to prevent collapse; the steel plate (arc) is bent, the net clamping film and the universal glue are used for fixing, air is filled, the load of the steel plate (pipe) can be increased greatly, the steel plate (pipe) can be built in a large span (more than 30 meters), a stand column is not needed for supporting the steel plate (pipe) in the middle, a truss structure in a steel structure is saved, and a large amount of steel is saved.

Example (b):

1. a temporary bridge channel is built between the deep ditches, the temporary bridge can be made only by a template, a net clamping film, universal glue and a check valve, the thickness of the plate is more than 5 cm, and the plate is convenient to glue and fix; the plate is wide enough and the film material is sufficient, so that the plate can be used as a large bridge to pass through automobiles and the like.

2. A temporary warehouse is built, an arched shed type warehouse framework can be rapidly built by using a bent template (made of wood, plastic, steel and the like) + a net clamping film + a check valve + a high-pressure air pump, and then canvas is used for covering. The framework has large span, no upright column and convenient disassembly. Can be used for building hangars, storehouses, temporary rest dormitories, meeting places and the like.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
