Description
Technical Field
The utility model relates to a pressure-bearing type block structure.
Background
The fireproof sealing is to seal the cable or pipeline with fireproof sealing material to pass through the wall or floor to form the hole, which is used to prevent the fire from spreading to the area adjacent to the fire source, so as to prevent the fire from spreading through the openings and gaps, and to protect the safety of personnel and equipment.
The basic principle of the fireproof plugging is that the plugging material plays roles of expansion, heat absorption and heat insulation, expands when meeting fire to seal a gap left by burning combustible substances, and prevents the fire and toxic gas and smoke generated in the fire from spreading; the heat absorption and the heat insulation are used for reducing the temperature of the back fire surface of the penetration object and preventing the combustible substance on the back fire surface from spontaneous combustion.
Common fire-proof blocking methods include cement pouring method, rock wool blocking method, inorganic fire-proof blocking method, organic fire-proof blocking method, fire retardant package blocking technology and suit fire retardant ring blocking technology
In the early days, people used cement infusion method to plug the vertical shaft, but the solidified plugging layer can generate bursting phenomenon after fire happens, so that plugging fails. In terms of plugging, the cable sheath is also easily scratched during pouring, and it is difficult to increase or decrease the cable after curing.
The rock wool plugging method has the advantages of low price, simple plugging, small increased building load and the like, has good fire resistance, but cannot tightly plug the pores of the cable bundle, and cannot plug the pores among fibers. As a result, in the event of a fire, although there is a significant fire-retardant effect, the smoke which has passed through the apertures is still sufficient to suffocate people. In addition, the presence of short fibers during construction is also harmful to the human body.
The inorganic fireproof blocking method is basically the same as the cement pouring method. But the blocking material curing layer is not afraid of fire burning and does not burst when meeting fire, thereby effectively playing a role of fire prevention. The disadvantage is that it is not easy to disassemble.
The organic fireproof blocking material has a good blocking effect on fire and smoke, and is convenient to detach and replace. However, the organic fireproof blocking material is generally soft and is only suitable for blocking a hole with a small blocking area, so that the organic fireproof blocking material has certain limitation. Therefore, when the organic fireproof blocking material is used only, small holes are blocked mostly.
The fire-retardant bag has excellent fire resistance, is convenient to plug and disassemble, and can quickly expand and plug the flue when being acted by a big fire, thereby effectively blocking the spread of dense smoke and flame. The only disadvantage is that the smoke can not be blocked in the early stage of fire, and the harmful smoke penetrating through the blocking layer seriously threatens the life safety of indoor personnel, so that the indoor personnel are poisoned, suffocated and even injured. And thus its application is also defective.
The technology is a latest fireproof sealing technology specially implemented for plastic pipes. The fire-retardant ring with corresponding specification is matched with the plastic pipe, and is suitable for the fireproof sealing of holes formed when various plastic pipes penetrate through walls and floors.
From the practical point of view, a single plugging material has more or less disadvantages. Therefore, at present, various fireproof plugging materials such as inorganic fireproof plugging materials, organic fireproof plugging materials, fire retardant bags, fire retardant rings and the like are often combined for use to complete fireproof plugging of the holes in the buildings.
However, when the construction position is too high, the temperature difference between two floors is large, the pressure is different, and when the electric elements are too much and the power is large, an electric field is formed, the electric field can cause the plugging structure to be damaged, meanwhile, the plugging material is broken and dropped to cause the damage of devices or the injury of personnel, and the existing plugging mode cannot solve the problems, so that a new plugging mode is needed.
