Pipeline penetrating floor fireproof structure

Abstract

The invention discloses a pipeline penetrating floor structure and particularly relates to a pipeline penetrating floor fireproof structure. The pipeline penetrating floor fireproof structure is composed of a sleeve pipe, foam glass, fireproof gypsum boards and sealant. A hole is reserved in a floor in advance. The sleeve pipe is embedded in the hole. The upper side and the lower side of the floor are respectively provided with the fireproof gypsum board in a laid mode. The foam glass is used for tightly sealing space among the inner diameter of the sleeve pipe, the outer diameter of a pipeline and the fireproof gypsum boards. The sealant is coated on joint portions of the fireproof gypsum boards and the pipeline. Due to adoption of the structure, a seam does not exist on the portion, where the pipeline penetrates, of the floor and fire endurance of the pipeline the same as that of the floor is achieved.

Description

technical field [0001] The invention relates to a structure for pipelines passing through floor slabs, in particular to a fireproof structure for pipelines passing through floor slabs. technical background [0002] There are holes where the pipes pass through the floor, if not handled carefully, there will be fire hazards. At present, the treatment methods for pipelines passing through floor openings mostly adopt the following two methods: one is to pour concrete into the gap between the pipeline and the floor to fill the gap. Since the pipeline and the slab are stuck together, the pipeline cannot be disassembled during maintenance, but can only be disassembled destructively. The second is to pre-embed the casing, but the gap between the casing and the pipe is insufficiently filled, which cannot reach the same fire resistance limit as the floor. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings and provi...

[0002] There are holes where the pipes pass through the floor, if not handled carefully, there will be fire hazards

At present, the following two methods are mostly used for the treatment of the opening of the pipeline passing through the floor: one is to pour concrete into the gap between the pipeline and the floor to fill the gap. Since the pipeline and the slab are stuck together, the pipeline cannot be disassembled during maintenance, but can only be disassembled destructively.

The second is to pre-embed the casing, but the gap between the casing and the pipe is not filled enough to reach the same fire resistance limit as the floor
