[0027] Example 1

[0028] like Figure 1-Figure 7As shown, the utility model provides an assembled fireproof partition, including a plurality of partition bodies 1 that are sequentially spliced ​​during installation, and the splicing method during assembly is: a clamping strip 102 is provided on one side of the partition body 1, and a clamping groove 101 is provided on the side of the partition body 1 opposite to the clamping strip 102, and the cross-sections of the clamping groove 101 and the clamping strip 102 are completely the same. During assembly, the clamping strip 102 on the second partition body 1 is clamped into the clamping groove 101 on the first partition body 1, and so on, the clamping strip on the third partition body 1 is clamped into the clamping groove 101 on the second partition body 1. In this embodiment, the cross-sections of the clamping strip 102 and the clamping groove 101 are both set to trapezoidal, and can also be set to other structures such as dovetail type, so that two partition bodies 1 can be quickly spliced.

[0029] At the same time, in order to realize the lifting work of the partition body 1, a detachable lifting ear 3 is also provided on the partition body 1. The lifting ear 3 is a C-shaped structure. The lifting ear 3 is installed on the partition body 1 through a bolt 2. The side of the partition body 1 is symmetrically provided with a connecting hole 103. The bolt 2 is threadedly connected with the connecting hole 103. When in use, the bolt 2 passes through the connecting plate 301 on the lifting ear 3, and the connecting plate 301 fits with the end face of the partition body 1. By arranging the lifting ear 3 on the surface of the partition body 1, it is convenient to lift the partition body 1. The number and setting position of the lifting ear 3 can be adaptively changed according to the size of the partition body 1.

[0030] A plurality of interlaced and interconnected air passages are provided inside the partition body 1. Specifically, the air passages include a plurality of interlaced and interconnected transverse air passages 104 and longitudinal air passages 105. The plurality of transverse air passages 104 and the plurality of longitudinal air passages 105 are interlaced and interconnected to form a grid structure. Several dry powder burst components are installed inside the air duct, and the dry powder burst components include a fixedly connected micro gas cylinder 4 and a dry powder storage box 5. The dry powder storage box 5 is fixedly connected to the micro gas cylinder 4 by several connecting rods 502. The diameter of the micro gas cylinder 4 is the same as the inner diameter of the longitudinal air duct 105. In this embodiment, the longitudinal air duct 105 penetrates to the top of the partition body 1, that is, the top surface of the partition body 1 is provided with several ports connected to the longitudinal air duct 105, and a stepped groove 1051 for clamping the micro gas cylinder 4 is opened at the port. The top of the micro gas cylinder 4 is provided with a limiting plate 401 that cooperates with the stepped groove 1051, so that the micro gas cylinder 4 can be clamped at the port of the longitudinal air duct 105.

[0031] The upper and lower ends of the dry powder storage box 5 are sealed by a film 501. Dry powder is stored in the dry powder storage box 5. The fire resistance limit of the wall refers to the time that the wall can remain intact when a fire occurs. It is classified according to national standards as 0.5 hours, 1 hour, 2 hours and 4 hours, etc. In the event of a fire, the temperature of the partition body 1 on the side of the fire will rise rapidly. When the temperature reaches the melting point of paraffin, the dry powder inside the dry powder storage box 5 will be filled into the transverse air duct 104 and the longitudinal air duct 105 inside the partition body 1 along with the high-pressure airflow. At this time, the dry powder can be reduced Low heat conduction efficiency can slow down the temperature rise rate on the other side of the partition body 1, thereby improving the thermal insulation of the partition body 1 and allowing the partition body 1 to last longer at the fire scene. In addition, when the partition body 1 is burned through by the fire, the partition body 1 loses its integrity. At this time, the dry powder inside the transverse air duct 104 and the longitudinal air duct 105 will be released. The dry powder can cover the solid combustion material to form an isolation layer that hinders combustion. At the same time, non-combustible gas is precipitated to reduce the oxygen concentration in the air, which can temporarily control the fire and provide more escape time for trapped people.

[0032] The micro gas cylinder 4 is provided with a nozzle 402 whose opening is toward the dry powder storage box 5, and a plug block 6 is clamped with paraffin inside the nozzle 402. The specific structure is: the nozzle 402 is provided with a clamping hole 4021 along its radial direction, and a paraffin block 601 is installed through the plug block 6. The paraffin block 601 is clamped and connected with the clamping hole 4021. The principle is: the melting point of paraffin is between 57-63°. After the paraffin block 601 melts at high temperature, the plug block 6 loses the blocking effect on the nozzle 402. At this time, the high-pressure gas inside the micro gas cylinder 4 will be ejected to break the film 501 on the surface of the dry powder storage box 5. The dry powder inside the dry powder storage box 5 will be filled in the transverse air duct 104 and the longitudinal air duct 105 under the action of the airflow, thereby improving the fireproof performance of the partition body 1.

[0033] Regarding the number of transverse air ducts 104 and longitudinal air ducts 105, in the implementation and application, workers can increase the number of longitudinal air ducts 105 according to actual conditions, so as to place more mini gas cylinders 4 and dry powder storage boxes 5 in the longitudinal air ducts 105, thereby improving the fireproof performance of the partition body 1.

[0034] The assembled fireproof partition is pre-installed with dry powder bursting components in several interlaced and interconnected air passages inside the partition body 1, and the opening of the micro gas cylinder 4 is blocked by the paraffin plug 6. In the technical solution, the dry powder can be mixed with ammonium carbonate, ammonium salt of phosphate and an appropriate amount of lubricant, and then ground into fine particles. These fine particles have a small mass. When the temperature in the space rises to a level sufficient to melt the paraffin, the paraffin block 601 melts and the plug 6 loses its blocking effect on the nozzle 402. At this time, the micro gas cylinder The high-pressure gas inside 4 will be ejected to break the film 501 on the surface of the dry powder storage box 5. At this time, the dry powder will be mixed in the high-pressure airflow, and the airflow mixed with the dry powder will fill the transverse air passage 104 and the longitudinal air passage 105. Due to the light weight of the dry powder particles, the dry powder will not settle to the bottom of the transverse air passage 104 and the longitudinal air passage 105 in a short time, but will be suspended in the transverse air passage 104 and the longitudinal air passage 105, thereby slowing down the heat conduction speed and improving the fireproof performance of the partition body 1.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
