Description

Air film building canopy face is personnel ladder about and safety rope net composite set on canopy

Technical Field

The utility model relates to the technical field of buildings, in particular to a ladder for a greenhouse surface of a gas film building and a safety rope net combination device on the greenhouse.

Background

The air film building structure has the characteristics of large span, no support structure in the air film building structure, large internal space, short building period and less investment, and in recent years, the buildings adopting the air film building structure are gradually increased, particularly, along with the improvement of the performance of the film materials and the extension of the service life, the single span and the building area of the air film building structure are gradually increased, the application field is also gradually wide, and particularly, along with the improvement of the environmental protection standard and the closed management of storage yards such as coal, the air film building structure is widely applied in the aspect of the storage yard sealing of the coal, and the good effect is obtained; the current air film building structure building and composition is shown in figure 1, and mainly comprises an exhaust valve 1 on a shed, a shed rope net steel cable 2, a film material shed surface 3, a bottom peripheral wall 4, a traveling door 5, a pedestrian door 6, a safety door 7, a climbing film pressure maintaining fan 8, a matched power system, a matched control system and the like.

The air film structure building is characterized in that the film surface and the cable net are lifted to form a stable closed space by means of air supply in the building by the film lifting fan, and the weight of the cable net on the greenhouse surface and various external loads acting on the film surface are supported by the air pressure in the building. The existing air film building needs to be subjected to the operation of a greenhouse surface by personnel, firstly, the electric exhaust valves on the greenhouse are inspected, maintained or replaced, and the greenhouse is provided with a large number of electric valve exhaust valves, the valves need to be inspected, maintained and replaced periodically in operation, and the operation of the valves needs to be carried out by personnel on the greenhouse surface; secondly, checking and maintaining the connection clamping plates between the greenhouse film materials and the connection clamps between the rope net steel cables, wherein the greenhouse film materials are connected by the clamping plates, the net rope steel cables are also connected by the clamps, and people need to check and maintain once the connecting piece is loosened and falls off; thirdly, removing dirt on a light-transmitting belt of the greenhouse surface, wherein the upper part of the greenhouse surface of the conventional air film building is provided with the light-transmitting belt for lighting in the daytime greenhouse, the light-transmitting belt can be polluted to influence the lighting effect in the greenhouse when the environment is influenced, and personnel are required to work on the greenhouse surface when the pollution of the light-transmitting belt is eliminated; fourthly, snow removal is a main factor restricting the application of the air film building in cold areas, with the increase of extreme weather such as heavy snow, the problem of solving the snow in the greenhouse area in the cold areas is more and more highly valued, although some ideas and related designs exist in the aspect of controlling the snow load of the greenhouse surface of the air film structure building at present, no good application effect is obtained, and before an ideal and operational greenhouse surface snow removal scheme is available, the snow removal of the artificial greenhouse surface is an effective method for avoiding the damage and slump of the air film building caused by the snow removal load of the current greenhouse surface, and the problem of climbing the greenhouse surface of personnel and the safety problem of the greenhouse surface operation are also required to be solved by implementing the snow removal of the artificial greenhouse surface.

The existing air film building is shown in the attached figure 1, the shape of the greenhouse surface is an arch with upward periphery, the greenhouse surface is an arc-shaped surface, and the gradient of the side wall is steep. No step climbs from the ground to the roof of the shed and no means for securing the harness is provided on the upper part. When the pressure in the greenhouse reaches the working pressure (about 270-300 Pa), the film material 3 and the cable net steel cable 2 are tightly adhered under the action of the gas pressure in the greenhouse, and the hands of people cannot stretch in, so that the existing gas film building personnel cannot go to the greenhouse surface under the condition of higher pressure in the greenhouse. When the operation of installing and debugging the exhaust valve 1 on the shed is performed at present, after the pressure in the shed is reduced to a certain degree, experienced professionals can climb to the shed surface through the rope grabbing net steel rope, and inexperienced non-professionals cannot climb up and have no safety guarantee. In order to ensure long-term safe and stable operation of the air film building, the problems of safe and smooth loading and unloading of the air film building and the safety of operation on the air film building must be solved.
