Abstract

The utility model discloses a flexible connection structure of an air film penetrating pipe. Comprising a gas film and a pipeline, a through hole is formed in the gas film, a flexible connecting sleeve is arranged at the position of the through hole, and the pipeline penetrates through the center of the flexible connecting sleeve; the flexible connecting sleeve comprises an inner ring, an outer ring and a flexible ring, the outer ring is fixedly connected to the through hole, the inner ring is connected with the outer wall of the pipeline, and the flexible ring is connected between the outer ring and the inner ring; the flexible ring is arranged in a wrinkled mode, and the flexible ring can extend in the radial direction. Through the arrangement of the flexible connecting sleeve and the steel plate ring, when the gas film moves, the flexible ring deforms, and therefore connection between the gas film and the pipeline is changed into flexible connection; the device adapts to deformation of the gas film structure, eliminates horizontal thrust generated by the deformation of the gas film structure on the film penetrating pipeline, prevents stress tearing of a hole position of the gas film structure, and guarantees safety and stability of the pipeline and a lower support. And meanwhile, the pipe penetrating hole is effectively sealed.

Description

Technical Field

[0001] The present application relates to the technical field of air film structure buildings, and in particular to an air film pipe-through-tube flexible connection structure. Background Art

[0002] Air film structures are widely used in stadiums, large storage yards and other fields because of their lightness, flexibility and ease of construction. In actual use, it is often necessary to set up pipe holes on the top of the air film structure for the passage of pipes, cables, etc. However, the existing pipe hole connection methods are mostly simple fixed, which not only has poor sealing, but also cannot adapt to the deformation of the air film structure. The deformation of the air film structure will produce horizontal thrust on the mold-penetrating pipe. The magnitude of this horizontal thrust is difficult to estimate, which will cause safety hazards to the design of the pipeline and the lower bracket, and cause the hole position of the air film structure to be torn by force.

[0005] An air film through-tube soft connection structure comprises an air film and a pipeline, wherein a through hole is opened on the air film, a soft connection sleeve is arranged at the through hole, and the pipeline is passed through the center of the soft connection sleeve; the soft connection sleeve comprises an inner ring, an outer ring and a flexible ring, the outer ring is fixedly connected to the through hole, the inner ring is connected to the outer wall of the pipeline, and the flexible ring is connected between the outer ring and the inner ring; the flexible ring is arranged as a pleat, and the flexible ring can be extended in the radial direction.

[0006] Optionally, a rigid ring is provided on the outer ring, and the rigid ring is fixedly connected to the through hole.

[0007] Optionally, a fixing ring is sleeved on the pipe, and the fixing ring is elastic; the inner ring is clamped between the pipe and the fixing ring.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] The present application adopts the setting of a soft connection sleeve and a steel plate ring, so that when the air film moves, the flexible ring is deformed, thereby turning the connection between the air film and the pipeline into a soft connection; it adapts to the deformation of the air film structure, eliminates the horizontal thrust of the air film structure deformation on the pipeline passing through the film, prevents the force tearing at the hole position of the air film structure, and ensures the safety and stability of the pipeline and the lower bracket; at the same time, it realizes the effective closure of the pipe hole.

[0017] The following is combined with Figure 1-3 This application is described in further detail.

[0018] The embodiment of the present application discloses a flexible connection structure for an air film 1 to pass through a pipe; the structure is used for connecting the air film 1 and the pipe 2, a through hole is opened on the air film 1, a flexible connection sleeve 3 is provided at the through hole, the flexible connection sleeve 3 is annular, and includes an inner ring 33, a flexible ring 32 and an outer ring; a rigid ring 31 is provided on the outer ring, the rigid ring 31 is fixedly connected to the through hole, the inner ring 33 is sleeved on the pipe 2, the flexible ring 32 is connected between the inner ring 33 and the outer ring, and is a flexible fabric that can be extended in a radial direction; when the through hole and the pipe 2 are concentric, the flexible ring 32 is in a wrinkled or bent state; therefore, when the air film 1 moves, the flexible ring 32 is deformed, thereby offsetting the impact on the pipe 2.

[0019] Specifically, the rigid ring 31 is designed in the form of a buckle, which is divided into two parts, an upper and lower part, with an empty groove for inserting the air membrane 1 between the two parts. When the upper and lower parts of the rigid ring 31 are buckled together, the air membrane 1 is stuck in the empty groove.

[0020] Specifically, the flexible connection sleeve 3 is connected to the pipe 2 via a fixed ring 4; the fixed ring 4 has movable elasticity, and the inner ring of the flexible connection sleeve 3 is tied to the pipe 2 by the fixed ring 4; the fixed ring 4 can be understood here as a rubber hoop; in order to ensure the sealing of the connection between the flexible connection sleeve 3 and the pipe 2, a sealing gasket 5 is also provided on the pipe 2, and the inner ring 33 is tied to the sealing gasket 5 by the fixed ring 4.

[0021] Since the flexible connection sleeve 3 is bent, in order to prevent water accumulation on the flexible connection sleeve 3, a steel plate ring 6 is also provided on the pipe 2, and the steel plate ring 6 is a conical ring; the inner ring 33 of the steel plate ring 6 is also clamped on the sealing gasket 5 by the fixed sleeve ring 4, and the outer ring of the steel plate ring 6 is placed on the air film 1, so rainwater will slide down along the steel plate ring 6 to avoid water accumulation.

[0022] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
