Problems solved by technology
[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

Embodiment Construction
[0009] As shown in Figure 1, this kind of fire-proof structure for pipelines passing through the floor requires a hole 50 mm larger than the outer diameter of the pipeline to be reserved on the floor, and a casing is embedded in the hole. The height of the casing is the same as the thickness of the floor. The floor is equipped with 10 thick fireproof gypsum boards, which are fixed and connected with nails. The length of the fireproof gypsum boards exceeds the casing by 150 mm, and the inner diameter of the casing, the outer diameter of the pipe and the fireproof gypsum board are sealed and compacted with foam glass. Apply sealant where the fireproof plasterboard meets the pipe.

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...
