Description

Technical Field

[0001] The utility model relates to the field of exterior protection materials, in particular to an arched sleeve block structure. Background Art

[0002] As people's awareness of environmental protection and safety increases, they have higher requirements for the safety of various external pipes used in daily life and production. Traditional pipe external protection is mostly simply wrapped with fireproof and anti-corrosion cloth, or PVE outer pipe is sleeved before docking. This is extremely inconvenient to install, maintain, and replace. Summary of the Invention

[0003] The utility model provides an arched sleeve block structure which has a simple structure, is easy to manufacture, and has the advantages of convenient installation, maintenance and stable protection.

[0004] The technical solution adopted by the utility model is: an arched block structure, including a plurality of multi-petal arched bodies evenly divided around a circumference and surrounding a complete circumference, characterized in that: the arched body includes an intermediate rubber-plastic layer, an upper glass fiber layer, a lower glass fiber layer, an upper thermal insulation cloth layer, a lower thermal insulation cloth layer and a peripheral thermal insulation cloth layer, all of which have arched cross-sections; the upper and lower end surfaces of the intermediate rubber-plastic layer are respectively bonded and hot-pressed with the upper and lower glass fiber layers; the upper and lower end surfaces of the upper and lower glass fiber layers are respectively bonded and hot-pressed with the upper and lower thermal insulation cloth layers; a circle of peripheral thermal insulation cloth layer is bonded and wrapped around the outer sides of the non-upper and lower end surfaces of the arched body.

[0005] The peripheral heat-insulating cloth layer is sewn at the joints formed by one circle.

[0006] The upper and lower thermal insulation cloth layers are made of Thinsulate base layers, which are covered by glass fiber mesh cloth layers on the upper and lower sides. The glass fiber mesh cloth layers are covered with aerogel layers, and the aerogel layers are covered with non-woven cloth layers and then hot-melt-pressed.

[0007] The peripheral thermal insulation cloth layer adopts a Thinsulate base layer covered by a glass fiber mesh cloth layer above and below, an aerogel layer is covered on the outside of the glass fiber mesh cloth layer, and a non-woven cloth layer is covered on the outside of the aerogel layer and then hot-melt pressed.

[0008] The joint is located on the arc-shaped edge with a small diameter of the arched body.

[0009] The beneficial effects of the present invention are as follows: the circumferential sleeve structure that needs to be wrapped around the outside of the pipeline is divided into multiple arched body structures, which is convenient for on-site assembly after the pipeline is laid; processing the arched body only requires cutting the arched middle rubber-plastic layer and the upper and lower glass fiber layers, and completing the cutting, gluing, and hot pressing molding in the factory, and then compounding the upper and lower thermal insulation cloth layers and gluing a circle of thermal insulation cloth layers around the periphery to form a complete arched sleeve block structure, taking into account the thickness of the sleeve block and external protection, meeting the requirements of structural strength, thermal insulation protection, etc. After on-site installation, local damage can be replaced by a separate sleeve block, and the production, installation and maintenance are convenient.
