[0017] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0018] See also Figure 1 The utility model provides a casing structure for a temporary fire-fighting water pipe outside a house, which solves the problems of water leakage caused by poor sealing during casing of existing temporary fire-fighting water pipes and difficulty in fixing the steel bars of the floor slab afterwards. By providing an inner water-stop ring and the outer water-stop ring, it is possible to more effectively prevent the accumulated water from entering the room along the water pipe. By providing the inner waterproof ring as metal, the steel bars of the floor slab can be welded on the inner waterproof ring, so as to facilitate pouring concrete in the casing for sealing.
[0019] See also Figure 1 , showing a top view of the fire water pipe casing structure of the utility model when it is exposed to the roof. Figure 2 , showing a cross-sectional view of the fire hose casing structure of the utility model when it is exposed to the roof. Figure 1 and Figure 2 , the utility model foundation pit combined supporting structure is explained.
[0020] like Figure 1 and Figure 2 As shown, the utility model is a casing structure for a temporary fire-fighting water pipe out of a roof, and its technical solution is as follows: a water pipe 2 passes upward through a roof slab 1, and the casing structure comprises: a casing 3 sleeved on the outside of the water pipe 2; an inner water stop ring 5 fixed on the inner wall of the casing 3, the inner water stop ring 5 is in close contact with the outer wall of the water pipe 2; and an outer water stop ring 4 fixed on the outer wall of the casing 3. By providing the inner water stop ring 5 and the outer water stop ring 4, water droplets can be effectively prevented from dripping from the side walls of the casing 3 and the water pipe 2 into the room.
[0021] In a specific implementation, the sleeve 3 and the outer water stop ring 4 are pre-buried in the roof slab 1 .
[0022] In a specific embodiment, the outer water-stop ring 4 and the inner water-stop ring 5 are made of metal material.
[0023] In a specific embodiment, a sealing ring is fixedly provided on the inner wall of the inner water stop ring 5 , and the sealing ring is tightly sealed against the outer wall of the water pipe 2 .
[0024] In a specific embodiment, the sealing ring is made of rubber material. By setting the sealing ring as rubber material, the rubber ring can be more closely fitted to the outer wall of the water pipe 2, thereby achieving a better waterproof effect.
[0025] In a specific embodiment, it also includes a floor steel bar 6 arranged in the casing 3 after the water pipe 2 is pulled out.
[0026] In a specific embodiment, the floor slab reinforcement 6 is fixedly connected to the inner water stop ring 5 .
[0027] In a specific embodiment, the floor slab reinforcement 6 and the inner water stop ring 5 are fixed by welding.
[0028] In a specific implementation, after the floor slab reinforcement 6 is fixed, concrete 7 is poured into the sleeve 3 to seal the sleeve 3 , and the upper and lower ends of the concrete 7 are aligned with the roof slab 1 .
[0029] In a specific implementation, after the concrete 7 solidifies, the sleeve 3 above the roof slab 1 is removed.
[0030] The following is a detailed description of the use process of the temporary fire-fighting water pipe casing structure of the utility model facing the house.
[0031] When the roof slab 1 is cast, the sleeve 3 is pre-buried in the roof slab 1 , and the outer water stop ring 4 outside the sleeve 3 is cast in the roof slab 1 .
[0032] Then the water pipe 2 is passed through the sleeve 3 so that the inner water stop ring 5 fits with the water pipe 2 to prevent the accumulated water from flowing into the room along the water pipe 2 .
[0033] After the construction is completed, the water pipe 2 is pulled out, the floor steel bar 6 is welded to the inner water stop ring 5, and then concrete 7 is poured into the sleeve 3 so that the poured concrete 7 is aligned with the upper and lower surfaces of the roof floor 1, thereby sealing the sleeve 3.
[0034] Finally, the upper and lower ends of the sleeve 3 leaking out from the roof floor 1 are cut off.
[0035] The utility model is described in detail above in conjunction with the embodiments of the drawings. A person skilled in the art can make various variations of the utility model according to the above description. Therefore, some details in the embodiments should not constitute a limitation of the utility model, and the scope of protection of the utility model shall be defined by the scope of the attached claims.
