Description

Technical Field

[0001] This utility model belongs to the field of duct construction technology, and in particular relates to a structure for a civil defense duct to penetrate a sealed partition wall. Background Technology

[0002] The shape of civil defense ventilation ducts is mainly rectangular, while circular ventilation ducts can be used in specific scenarios. Civil defense ventilation ducts cannot be drilled directly through the wall. Instead, a special sealed wall penetration short pipe is used for civil defense projects. The sealed short pipe is pre-embedded in the wall when the concrete is poured. Then, the ventilation duct is inserted into the sealed short pipe for sealing connection to ensure the airtightness of the civil defense ventilation duct.

[0003] Civil defense ventilation ducts are mainly installed by pre-embedded sealed wall-penetrating short pipes. When in use, the sealed wall-penetrating short pipes need to be sealed at both ends to connect to the ventilation duct. The ventilation duct is heavy, which may cause the sealed wall-penetrating short pipe to tilt due to external load. Therefore, a structure for civil defense ventilation ducts to penetrate sealed partition walls is needed. The sealed wall-penetrating short pipes can be reinforced by a reinforcement structure to prevent them from tilting during use and to ensure the stability of the civil defense ventilation ducts penetrating the wall. Utility Model Content

[0004] The purpose of this utility model is to provide a structure for a ventilator to pass through a sealed partition wall. This structure can reinforce the sealed wall-penetrating short pipe, preventing it from tilting during use and ensuring the stability of the ventilator passing through the wall, thus solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A structure for a civil defense air duct penetrating a sealed partition wall includes sealing rings set on the front and back of the wall. A penetrating pipe is provided through the front of the wall. The sealing ring is sleeved on the surface of the penetrating pipe. A decorative strip is provided at the connection between the sealing ring and the penetrating pipe. Two symmetrical anti-slip strips are provided at the top and bottom of the penetrating pipe. Two symmetrical support frames one are provided at the bottom of the penetrating pipe. Two symmetrical support frames two are provided at the top of the penetrating pipe. Two longitudinal threaded rods are provided through the top of the support frames two. The threaded rods penetrate the support frames two and one to the bottom of the support frames one. Two symmetrical nuts are threadedly connected to the surface of the threaded rods. Two symmetrical fixing rods are fixedly connected to the front of the support frames two. Fixing frames are fixedly connected to both the front and back of the wall. Two symmetrical hanging rods one are provided through the bottom of the fixing frames. The bottom of the hanging rods one is rotatably connected to the fixing rods. Two symmetrical nuts are threadedly connected to the surface of the hanging rods one.

[0006] Preferably, two symmetrical hangers are provided on both the front and back of the wall, and the hangers are attached to the bottom of the through-wall pipe.

[0007] Preferably, the top of the hanger is provided with two symmetrical hanger rods, and the top of the hanger rods is fixedly connected to a connecting frame.

[0008] Preferably, an expansion bolt is fixedly connected to the top of the connecting frame, and the expansion bolt is fixedly connected to the wall and top plate.

[0009] Preferably, the top of the hanger is provided with two symmetrical limiting members, the top of which are provided with bolts, the bolts passing through the limiting members and the hanger and being threadedly connected with nuts.

[0010] Preferably, protective heads are provided at both ends of the hanger, and the protective heads are adapted to the two ends of the hanger.

[0011] The beneficial effects of this utility model are: 1.

[0014] In the following description, embodiments of the civil defense ventilation pipe penetrating a sealed partition wall according to the present invention will be presented with reference to the accompanying drawings: Figure 1-4 This invention illustrates an embodiment of a blast wall ventilation pipe penetrating a sealed partition wall, comprising sealing rings 2 disposed on the front and back of a wall 1, two symmetrical hangers 12 disposed on both the front and back of the wall 1, the hangers 12 being fitted to the bottom of the through-wall pipe 3, and two symmetrical suspension rods 13 penetrating the top of the hangers 12, the top of which is fixedly connected to a connecting frame 14, and the top of the connecting frame 14 is fixedly connected to an expansion bolt 15, which is fixedly connected to the top of the wall panel. The top of the hanger 12 is provided with two symmetrical limiting members 16, and bolts are inserted through the top of the limiting members 16 and the hanger 12. The bolts are threaded through the limiting members 16 and the hanger 12 and are connected with nuts. Protective heads 17 are provided at both ends of the hanger 12, and the protective heads 17 are adapted to the two ends of the hanger 12. A through-wall pipe 3 is provided through the front of the wall 1. A sealing ring 2 is fitted on the surface of the through-wall pipe 3. A decorative strip 4 is provided at the connection between the sealing ring 2 and the through-wall pipe 3. Two pairs of nuts are provided at the top and bottom of the through-wall pipe 3. The anti-slip strip 5 increases the friction between the support frame 1 6 and the support frame 2 7 and the through-wall pipe 3 when the support frame 1 6 and the support frame 2 7 are fixed to the surface of the through-wall pipe 3. This prevents the through-wall pipe 3 from sliding between the support frame 1 6 and the support frame 2 7, thus ensuring the stability of the through-wall pipe 3. Two symmetrical support frames 1 6 are set at the bottom of the through-wall pipe 3, and two symmetrical support frames 2 7 are set at the top of the through-wall pipe 3. Two longitudinal threaded rods 8 are set through the top of the support frame 2 7. The threaded rods 8 pass through the support frame 2 7 and the support frame 1 6 to the bottom of the support frame 1 6. Two symmetrical nuts are threaded on the surface of the threaded rods 8. Two symmetrical fixing rods 9 are fixedly connected to the front of the support frame 2 7. Fixing frames 10 are fixedly connected to the front and back of the wall 1. Two symmetrical hanging rods 11 are set through the bottom of the fixing frames 10. The bottom of the hanging rods 11 is rotatably connected to the fixing rods 9. Two symmetrical nuts are threaded on the surface of the hanging rods 11.

[0015] Working Principle: When using this utility model, the user places support frame 6 and support frame 7 at the bottom and top of the through-wall pipe 3, respectively, so that the threaded rod 8 passes through support frame 6 and support frame 7. The two nuts on the surface of the threaded rod 8 are rotated to fit against support frame 6 and support frame 7, thus fixing support frame 6 and support frame 7. Then, the fixing frame 10 is fixed to the front and back of the wall 1, so that the top of the hanger 11 passes through the fixing frame 10, and the bottom of the hanger 11 is rotatably connected to the fixing rod 9. This completes the reinforcement of the through-wall pipe 3, preventing the sealed through-wall pipe from tilting during use and ensuring the stability of the ventilation duct through the wall. When support frame 6 and support frame 7 are fixed on the surface of the through-wall pipe 3, the anti-slip strip 5 increases the friction between support frame 6 and support frame 7 and the through-wall pipe 3, preventing slippage between support frame 6 and support frame 7 and ensuring the stability of the through-wall pipe 3.

[0016] In summary, this structure for a personnel-proof ventilation duct penetrating a sealed partition wall, by placing support frame 1 (6) and support frame 2 (7) at the bottom and top of the through-wall pipe 3 respectively, and fixing support frame 1 (6) and support frame 2 (7) with threaded rod 8 and nuts, and then fixing fixing frame 10 to the front and back of the wall 1, and allowing hanging rod 11 to pass through fixing frame 10 and be rotatably connected to fixing rod 9, can achieve the reinforcement of the sealed through-wall short pipe through the reinforcement structure, preventing the sealed through-wall short pipe from tilting during use and ensuring the stability of the personnel-proof ventilation duct penetrating the wall.
