Description

Technical Field

[0001] This utility model belongs to the technical field of cryogenic tank ceiling structure, specifically relating to an edge sealing structure for a cryogenic tank ceiling. Background Technology

[0002] Cryogenic storage tanks store cryogenic media. The existing tank structure includes an inner tank wall with a reinforcing ring at the top. A suspended ceiling is required at the top opening of the tank, which fits into the inner tank wall. Insulation material is also required at the junction of the suspended ceiling and the tank. To prevent the insulation material from entering the tank, the edges of the suspended ceiling need to be sealed. Additionally, fiberglass cloth needs to be laid outside the insulation material. Currently, there is no good structure for fixing the fiberglass cloth. Utility Model Content

[0003] This utility model addresses the aforementioned problems by providing an edge sealing structure for the ceiling of a cryogenic tank with good sealing performance.

[0004] The present invention adopts the following technical solution: the present invention includes a suspended ceiling, the suspended ceiling includes a frame composed of a ring beam and a radial beam, and a suspended ceiling plate is provided above the frame. The feature is that: a lateral baffle is fixedly provided outside the frame of the suspended ceiling, the upper end of the lateral baffle is higher than the upper surface of the inner tank wall, and the lower end of the lateral baffle cooperates with the upper surface of the reinforcing ring on the inner tank wall.

[0005] As a preferred embodiment of this utility model, the upper end of the side baffle is provided with a glass fiber cloth fixing plate and a clamping plate.

[0006] As another preferred embodiment of this utility model, the upper end of the side baffle is 200-300mm higher than the upper surface of the ceiling.

[0007] As a third preferred embodiment of this utility model, the distance between the lower end of the side baffle and the upper surface of the reinforcing ring is 0-5mm.

[0008] As a fourth preferred embodiment of the present invention, the outer end of the radial beam of the skeleton is flush with the outer contour of the outermost ring beam; the lateral baffle is fixed on the outer contour of the outermost ring beam.

[0009] As a fifth preferred embodiment of this utility model, a profiled top plate is provided above the frame.

[0010] The beneficial effects of this utility model are: the side baffle of this utility model can prevent the insulation material on the side of the ceiling from entering the storage tank, and at the same time it also has the function of fixing the fiberglass cloth. The structure is simple and the construction is convenient. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of this utility model.

[0012] In the attached diagram, 1 is the radial beam, 2 is the ring beam, 3 is the profiled top plate, 4 is the fiberglass cloth fixing plate and clamping plate, 5 is the side baffle, 6 is the reinforcing ring, and 7 is the inner tank wall.

[0013] In the attached diagram, H is the upper surface of the inner tank wall, L is the upper surface of the reinforcing ring, and A is the upper surface of the ceiling. Detailed Implementation

[0014] The present invention adopts the following technical solution: the present invention includes a suspended ceiling, the suspended ceiling includes a frame composed of a ring beam 2 and a radial beam 1, a suspended ceiling plate is provided above the frame, and a side baffle 5 is fixedly provided outside the frame of the suspended ceiling. The upper end of the side baffle 5 is higher than the upper surface of the inner tank wall 7, and the lower end of the side baffle 5 cooperates with the upper surface of the reinforcing ring 6 on the inner tank wall 7.

[0015] By setting a lateral baffle 5 on the outside of the ceiling frame, and the upper and lower ends of the baffle form a matching structure with the inner tank wall 7 and the reinforcing ring 6, the gap area between the ceiling and the tank body can be effectively sealed to prevent the insulation material from entering the interior of the cryogenic storage tank from the side.

[0016] The upper end of the side baffle 5 is provided with a glass fiber cloth fixing plate and a clamping plate 4.

[0017] By adding a fiberglass cloth fixing plate and a clamping plate 4 to the top of the side baffle 5, the outer fiberglass cloth can be firmly fixed to the edge of the ceiling to prevent it from slipping or deforming, thereby enhancing the overall sealing performance and construction reliability of the insulation layer.

[0018] The upper end of the side baffle 5 is 200-300mm higher than the upper surface of the ceiling.

[0019] The upper surface of the ceiling is the upper surface of the skeleton, which is the upper surface of radial beam 1.

[0020] By extending the upper end of the side baffle 5 200-300mm above the upper surface of the ceiling, sufficient installation space can be provided for the covering and fixing of the fiberglass cloth, while forming a physical barrier of a certain height to improve the protective capability.

[0021] The distance between the lower end of the side baffle 5 and the upper surface of the reinforcing ring 6 is 0-5 mm.

[0022] By controlling the gap between the lower end of the side baffle 5 and the reinforcing ring 6 to be within 0-5mm, the structural connection is ensured to meet the usage requirements.

[0023] The outer end of the radial beam 1 of the skeleton is flush with the outer contour of the outermost ring beam 2; the lateral baffle 5 is fixed on the outer contour of the outermost ring beam 2.

[0024] The side baffle 5 is directly fixed to the outer contour of the outermost ring beam 2 of the frame, making it a natural extension of the ceiling structure. This simplifies the installation process and improves the installation strength and stability of the baffle.

[0025] A profiled top plate 3 is provided above the frame.

[0026] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
