Abstract
Description
Technical Field
[0001] The utility model relates to the field of building facilities, and particularly relates to a fire prevention facility for building pipelines. Background Art
[0002] According to GB / T51410 "Technical Standard for Application of Building Fireproof Sealing", when a metal pipeline passes through a fireproof partition wall, and there are combustibles near the passing point, in order to prevent high temperature on one side of the fireproof wall from being transmitted to the other side through the metal pipeline and igniting the combustibles after a fire occurs on one side of the fireproof wall, it is stipulated that fireproof and heat insulation measures must be taken for the metal pipeline within 1m on both sides of the fireproof wall.
[0003] The pipeline fireproof and heat insulation measures in the related art are usually divided into three types, and the specific practices are as follows:
[0004] The first type: If the metal pipeline has no heat insulation layer, it is necessary to wrap a flame retardant heat insulation material with a thickness of not less than 40mm on the metal pipeline within 1m on both sides of the wall.
[0005] The second type: If the heat insulation layer wrapped on the metal pipeline is made of combustible materials, it is necessary to replace the heat insulation layer on the metal pipeline within 1m on both sides of the wall with a heat insulation layer made of flame retardant heat insulation materials.
[0006] The third type: If the heat insulation layer wrapped on the metal pipeline is made of flame retardant materials, normal construction can be carried out.
[0007] Currently, for the second situation, usually the heat insulation layer made of rubber sponge material wrapped on the metal pipeline is replaced with a heat insulation layer made of centrifugal glass wool. However, since the thermal conductivity of centrifugal glass wool is higher than that of rubber and plastic sponge, if the metal pipeline wants to meet the fireproof and heat insulation conditions, a thicker glass wool heat insulation layer needs to be wrapped on the metal pipeline. Therefore, by adopting this method, the outer diameter of the building pipeline will be increased, and when the building pipelines are relatively dense, it will affect the arrangement of the building pipelines. Moreover, the heat insulation layer made of glass wool material is relatively loose, and the outer surface of the heat insulation layer is uneven, thus affecting the appearance quality of the building pipeline, which needs to be improved. Content of the Utility Model
[0008] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a fire prevention facility for building pipelines, which can ensure the fireproof and heat insulation effect of the building pipelines, while ensuring the outer diameter size of the building pipelines, reducing the risk of interference between the building pipelines, and at the same time improving the appearance quality of the building pipelines.
[0009] The above technical object of the present utility model is achieved through the following technical solutions: A fire prevention facility for building pipelines includes two semi-circular fireproof shells, and the two fireproof shells are spliced to form a cylindrical fireproof sleeve for sleeving on the building pipeline. Inner side surfaces of the two fireproof shells are respectively fixedly connected with semi-circular heat insulation plates, and the two heat insulation plates are spliced to form a cylindrical heat insulation sleeve for tightly wrapping on the building pipeline. The fireproof shells and the heat insulation plates are respectively made of flame retardant materials.
[0010] In a preferred example, the present utility model can be further configured as: A plurality of fixing ears are symmetrically arranged at two sides of the two fireproof shells respectively, and the fixing ears on the two fireproof shells correspond to each other in pairs and are respectively connected by fastening bolts.
[0011] In a preferred example, the present utility model can be further configured as: The length of the fireproof shell is not less than 1 m and the thickness is 5 - 10 mm.
[0012] In a preferred example, the present utility model can be further configured as: Anti-slip patterns are respectively arranged on inner side surfaces of the two heat insulation plates.
[0013] In a preferred example, the present utility model can be further configured as: One ends of the two fireproof shells are respectively fixedly connected with assembly plates, the assembly plates are used for abutting against the wall surface, and assembly holes for expansion screws to pass through are respectively arranged on each assembly plate.
[0014] In a preferred example, the present utility model can be further configured as: The two assembly plates are respectively semi-circular rings, and the two assembly plates are spliced to form an annular flange.
[0015] In a preferred example, the present utility model can be further configured as: A positioning post is arranged on one of the assembly plates, a positioning groove is arranged on the other assembly plate, and after the two assembly plates are spliced, the positioning post is tightly inserted into the positioning groove.
[0016] In summary, the present utility model has at least the following beneficial effects:
[0017] By wrapping the building pipeline with the fireproof shells and heat insulation plates made of flame retardant materials, compared with wrapping a thicker heat insulation layer on the building pipeline, this design can ensure the fireproof and heat insulation effects of the building pipeline, and ensure the outer diameter size of the building pipeline to reduce the risk of interference between building pipelines. At the same time, this design can facilitate the relevant operations of the staff, improve the construction efficiency, and also improve the appearance quality of the building pipeline.

[0022] The present invention will be described in further detail below with reference to the accompanying drawings.
[0023] Reference Figure 1 、 Figure 2 A fireproofing device for building pipes includes two semicircular fireproof shells 1, which, when joined, form a cylindrical fireproof sleeve for use over building pipes. Semicircular insulation panels 2 are fixedly attached to the inner surfaces of the two fireproof shells 1. When joined, the two insulation panels 2 form a cylindrical insulation sleeve for tightly wrapping around building pipes.
[0024] Reference Figure 1 、 Figure 2 A plurality of fixing ears 3 are symmetrically arranged on both sides of the two fireproof shells 1, and the fixing ears 3 on the two fireproof shells 1 correspond to each other in pairs and are connected by fastening bolts 4 to achieve a stable connection between the two fireproof shells 1.
[0025] In this embodiment, the fireproof shell 1 is no less than 1 meter long and 5-10 mm thick. It is made of a fire-retardant material such as glass magnesium board. The insulation board 2 can be made of a fire-retardant material such as STP ultra-thin insulation board 2. STP ultra-thin insulation board 2 has excellent thermal conductivity and is non-flammable, allowing for effective thickness control.
[0026] The flame-retardant fireproof shell 1 and insulation board 2 are wrapped around the building pipes. Compared to wrapping the pipes with thicker insulation layers, this design can ensure the fireproof and heat-insulating effects of the building pipes, while also ensuring the outer diameter of the building pipes is within the specified range, thereby reducing the risk of interference between the building pipes. This design also facilitates work and improves construction efficiency. The outer surface of the fireproof shell 1 is smoother and flatter, thereby improving the appearance of the building pipes.
[0027] Reference Figure 2 、 Figure 3, anti-slip patterns are integrally formed on the inner surfaces of the two heat insulation plates 2 respectively to increase the friction between the heat insulation plates 2 and the building pipes, thereby improving the connection stability between the fire prevention facilities and the pipes and reducing the risk of displacement of the fire prevention facilities.
[0028] Refer to Figure 1 , Figure 2 , one ends of the two fireproof shells 1 are respectively fixedly connected with assembly plates 5. The assembly plates 5 are used to tightly press against the wall surface, and through holes for expansion screws to pass through are respectively formed in each assembly plate 5 to achieve stable connection between the fire prevention facilities and the wall.
[0029] Refer to Figure 2 , Figure 3 , the two assembly plates 5 are respectively in a semi-circular ring shape, and the two assembly plates 5 form an annular flange after being spliced to improve the aesthetic appearance. At the same time, a positioning post 7 is arranged on one of the assembly plates 5, a positioning groove 8 is arranged on the other assembly plate 5, and after the two assembly plates 5 are spliced, the positioning post 7 is tightly inserted into the positioning groove 8, which can not only realize the installation limit of the two assembly plates 5, but also improve the connection stability of the two assembly plates 5.

Those skilled in the art can make modifications without creative contributions to the embodiments according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
