Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a high-temperature resistant cement inner cylinder hanging sheet. Background Art

[0002] Cement inner tube hanging plate is a component used in the construction industry, usually refers to the steel bar hanging inside the concrete structure for the purpose of strengthening or repairing the building. These steel bars can provide additional support and stability, and improve the strength and durability of the entire structure.

[0003] Cement inner tube hanging plates are mainly used in high temperature environments such as chimneys, boiler flues, hot air ducts, etc. In these environments, the hanging plates are easily subject to high temperature corrosion and oxidation, resulting in decreased structural strength and shortened service life. Therefore, special high temperature resistant hanging plates are needed to protect the inner tube and extend its service life. Summary of the invention

[0004] In order to solve the above technical problems, the utility model provides a high temperature resistant cement inner cylinder hanging sheet.

[0005] The utility model adopts the following technical scheme: a high temperature resistant cement inner cylinder hanging piece, comprising a mud cylinder, the inner wall of the mud cylinder is provided with a connecting hanging piece body, the middle part of the rear end of the connecting hanging piece body is provided with a heat insulation structure, and the front end of the connecting hanging piece body is provided with a guide groove;

[0006] The heat insulation structure comprises a middle partition, one side of which is fixedly connected to the middle of the rear end of the connecting hanging piece body, a first groove is provided in the middle of the surface of the middle partition, and a heat insulation layer is provided inside the first groove.

[0007] Through the above technical solution, the thermal insulation layer filled in the first groove arranged on one side of the middle partition can effectively block the transfer of heat, reduce the thermal shock of the connecting hanging piece body, and improve the overall high temperature resistance. At the same time, due to the protective effect of the thermal insulation layer, the material of the connecting hanging piece body will not deteriorate due to long-term exposure to high temperature environment, thereby extending the service life of the connecting hanging piece body. In addition, since the thermal insulation structure is designed inside the connecting hanging piece body, it does not affect external operation and maintenance, and is convenient for inspection and replacement of the connecting hanging piece body.

[0008] As a further improvement of the above solution, the material of the heat insulation layer is glass wool, and there are several connecting hanging plate bodies, which are evenly arranged on the inner wall of the mud cylinder.

[0009] Through the above technical solution, glass wool is a thermal insulation material that can effectively prevent the transfer of heat, thereby reducing the temperature exchange inside and outside the mud barrel and maintaining the temperature inside the mud barrel stable. In addition, the glass wool material is relatively light and has a small structural load on the mud barrel, making it easy to install and maintain.

[0010] As a further improvement of the above solution, the rear end of the connecting hanging piece body is fixedly connected with an auxiliary side block, and the number of the auxiliary side blocks is two, which are respectively fixedly connected to the two sides of the rear end of the connecting hanging piece body.

[0011] Through the above technical solution, the auxiliary side blocks provide additional support to help disperse the force borne by the connecting hanging piece body, thereby increasing the stability of the entire structure. When the connecting hanging piece body is subjected to lateral force, the auxiliary side blocks can provide resistance to prevent the connecting hanging piece body from being pushed over or sliding.

[0012] As a further improvement of the above solution, a second groove is formed on the surface of the auxiliary side block.

[0013] Through the above technical solution, by opening a second groove on the auxiliary side block and placing an adhesive plate, the contact area with other components can be increased, thereby enhancing the strength of bonding or connection. The second groove can provide an embedded space for the adhesive plate, so that the adhesive plate can fit the auxiliary side block more closely, which can improve the bonding effect and avoid the peeling problem that may occur due to direct plane bonding.

[0014] As a further improvement of the above solution, an adhesive plate is provided inside the second groove.

[0015] Through the above technical solution, the adhesive plate can increase the bonding effect between the connecting hanging piece body and the mud barrel, thereby improving the bonding strength and the stability of the connection, and through bonding, it is convenient for personnel to subsequently disassemble and replace the connecting hanging piece body.

[0016] As a further improvement of the above solution, the surface of the adhesive plate is made of epoxy resin, and heat dissipation ducts are provided on both sides of the front end of the connecting hanging piece body.

[0017] Through the above technical solution, epoxy resin is a widely used adhesive with good heat resistance. Depending on the formulation, it can withstand higher temperatures, thereby improving the high temperature resistance of the surface of the connecting hanging piece.

[0018] As a further improvement of the above solution, the outer surface of the front end of the connecting hanging piece body is provided with a refractory coating, and the material of the refractory coating is oxide ceramic.

[0019] Through the above technical solution, the oxide ceramic has good high temperature resistance, which can protect the connecting hanging piece body from the influence of high temperature environment, effectively prevent heat from being transferred to the inside of the connecting hanging piece body, and avoid melting or deformation of the connecting hanging piece body.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The utility model provides a heat insulation structure, and the heat insulation layer filled in the first groove arranged on one side of the middle partition can effectively block the transfer of heat, reduce the thermal shock to the connecting hanging piece body, and improve the overall high temperature resistance. At the same time, due to the protective effect of the heat insulation layer, the material of the connecting hanging piece body will not deteriorate due to long-term exposure to a high temperature environment. Combined with the refractory coating, it can effectively prevent heat from being transferred to the inside of the connecting hanging piece body, thereby extending the service life. In addition, since the heat insulation structure is designed inside the connecting hanging piece body, it does not affect external operation and maintenance, and is convenient for overhauling and replacing the connecting hanging piece body.
