Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a sealing and protective structure for the roof-penetrating nodes of water supply and drainage pipes in building engineering. Background Technology

[0002] In building construction, the treatment of pipe penetrations through the roof has always been a critical and challenging issue. Since pipes need to pass through the top of buildings, gaps and holes inevitably form at these penetration points. Improper handling of these gaps and holes can lead to leaks of rainwater and sewage, affecting the normal use of the building and potentially threatening its structural safety. Traditional sealing methods for pipe penetrations often involve simple filling materials such as cement mortar or asphalt. However, these materials are prone to cracking and aging during use, resulting in poor sealing performance. Furthermore, traditional sealing methods lack effective means for pipe positioning and fixation, making them susceptible to displacement under pipe vibration or external forces, further affecting sealing performance. To address these problems, this invention proposes a sealing and protection structure for pipe penetrations through the roof in building construction. Utility Model Content

[0003] The purpose of this utility model is to provide a sealing and protective structure for the roof penetration joint of water supply and drainage pipes in building engineering, so as to solve the above-mentioned technical problems. To achieve the above purpose, this utility model adopts the following technical solution: A sealing and protective structure for the roof penetration node of water supply and drainage pipelines in building engineering includes an upper positioning sleeve, a lower positioning sleeve, an upper waterproof sealing plate, a lower leak-proof sealing plate, and a solidified integrated sleeve. The upper and lower positioning sleeves are symmetrically arranged at the upper and lower ends of the solidified integrated sleeve. The upper waterproof sealing plate is fitted in the middle section of the upper positioning sleeve, and the lower leak-proof sealing plate is fitted in the middle section of the lower positioning sleeve.

[0004] Based on the above technical solution, the upper waterproof sealing plate is composed of a circular rigid plate with an extra-large perforation diameter and a surface rubber gasket. The circular rigid plate with an extra-large perforation diameter is tightly attached to the top side of the surface rubber gasket, and the size of the circular rigid plate with an extra-large perforation diameter and the surface rubber gasket are similar. The lower leak-proof sealing plate is composed of a circular rigid plate with a near-perforation diameter and a surface rubber gasket. The surface rubber gasket is tightly attached to the top side of the circular rigid plate with a near-perforation diameter, and the size of the circular rigid plate with a near-perforation diameter and the surface rubber gasket are similar. Both the circular rigid plate with an extra-large perforation diameter and the circular rigid plate with a near-perforation diameter have staggered openings. The circular rigid plate with an extra-large perforation diameter and the surface rubber gasket are fitted into the middle section of the upper positioning sleeve, and the circular rigid plate with a near-perforation diameter and the surface rubber gasket are fitted into the middle section of the lower positioning sleeve.

[0005] Based on the above technical solution, both the upper and lower positioning sleeves are composed of an outer rubber sleeve, a thickened section of the sleeve, and a positioning groove in the thickened section. The thickened section is located in the middle section of the outer rubber sleeve, and the positioning groove is located in the middle section of the thickened section. The outer rubber sleeve and the thickened section are integrally formed. The extra-large perforation diameter circular rigid plate and the near-perforation diameter circular rigid plate are correspondingly fitted into the positioning groove in the thickened section of the upper positioning sleeve. The near-perforation diameter circular rigid plate and the facing... The rubber gasket is fitted into the thickened section positioning groove in the lower positioning sleeve. The solidified integrated sleeve consists of an outer rubber sleeve, a reinforcing steel wire core, and an outer sealing rubber. Several sets of reinforcing steel wire cores are provided, and the inner ends of the several sets of reinforcing steel wire cores are fixed on the outer rubber sleeve. The outer sealing rubber covers the outer side of the reinforcing steel wire core. The upper positioning sleeve and the lower positioning sleeve are respectively tightly attached to the upper and lower sides of the outer rubber sleeve in the solidified integrated sleeve.

[0006] This structure, through the combined use of an upper positioning sleeve, a lower positioning sleeve, an upper waterproof sealing plate, a lower leak-proof sealing plate, and a solidified integrated sleeve, effectively seals and protects the overhead penetration points of water supply and drainage pipes. The upper and lower positioning sleeves are symmetrically positioned at the upper and lower ends of the solidified integrated sleeve, serving to position and fix the pipes. The upper waterproof sealing plate and lower leak-proof sealing plate are respectively fitted into the middle sections of the upper and lower positioning sleeves, achieving a tight seal against gaps and holes through their special structure and materials. The solidified integrated sleeve, with its internal reinforcing steel wire core and external sealing rubber coating, enhances the overall strength and sealing performance of the structure.

[0007] This novel sealing and protective structure not only boasts excellent sealing performance but also effectively resists pipe vibration and external forces, ensuring the normal use and structural safety of buildings. Furthermore, it offers advantages such as easy installation and maintenance, providing a new solution for handling roof penetrations of water supply and drainage pipes in building construction.

[0008] Compared with the prior art, the present invention has the following advantages: The present invention optimizes the setting of the protective structure for water supply and drainage pipes penetrating the roof in buildings. By using a combined structure, the upper and lower ends of the perforation are sealed and fixed respectively. At the same time, an internal structure is added to make it mutually structured with the fixing object, which enhances the stability of the pipe and strengthens the sealing effect. It is suitable for widespread use. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] A sealing and protective structure for the roof penetration node of water supply and drainage pipelines in building engineering includes an upper positioning sleeve 1, a lower positioning sleeve 2, an upper waterproof sealing plate 3, a lower leak-proof sealing plate 4, and a solidified integrated sleeve 5. The upper positioning sleeve 1 and the lower positioning sleeve 2 are symmetrically arranged at the upper and lower ends of the solidified integrated sleeve 5. The upper waterproof sealing plate 3 is fitted in the middle section of the upper positioning sleeve 1, and the lower leak-proof sealing plate 4 is fitted in the middle section of the lower positioning sleeve 2.

[0016] The above are the main components of the sealing and protective structure, and their relative positions. (See attached diagram.) Figure 1 and attached Figure 2 .

[0017] The upper waterproof sealing plate 3 is composed of a circular rigid plate 6 with an extra-large perforation diameter and a rubber gasket 7. The circular rigid plate 6 with an extra-large perforation diameter is tightly attached to the top side of the rubber gasket 7, and the circular rigid plate 6 with an extra-large perforation diameter and the rubber gasket 7 are approximately the same size. The lower leak-proof sealing plate 4 is composed of a circular rigid plate 8 with a near-perforation diameter and a rubber gasket 7. The rubber gasket 7 is tightly attached to the top side of the circular rigid plate 8 with a near-perforation diameter, and the circular rigid plate 8 with a near-perforation diameter and the rubber gasket 7 are approximately the same size. Both the circular rigid plate 6 with an extra-large perforation diameter and the circular rigid plate 8 with a near-perforation diameter have staggered openings 9. The circular rigid plate 6 with an extra-large perforation diameter and the rubber gasket 7 are fitted into the middle section of the upper positioning sleeve 1, and the circular rigid plate 8 with a near-perforation diameter and the rubber gasket 7 are fitted into the middle section of the lower positioning sleeve 2.

[0018] The above describes the main structural components of the upper waterproof sealing plate 3 and the lower leak-proof sealing plate 4, as well as their corresponding connection and positional relationships. (See attached diagram.) Figure 3.

[0019] Both the upper positioning sleeve 1 and the lower positioning sleeve 2 are composed of an outer rubber sleeve 10, a thickened section 11, and a positioning groove 12 in the thickened section. The thickened section 11 is located in the middle section of the outer rubber sleeve 10, and the positioning groove 12 is located in the middle section of the thickened section 11. The outer rubber sleeve 10 and the thickened section 11 are integrally formed. The extra-large perforation diameter circular rigid plate 6 and the near-perforation diameter circular rigid plate 8 are correspondingly fitted into the positioning groove 12 in the thickened section of the upper positioning sleeve 1. The near-perforation diameter circular rigid plate 8 and the facing rubber gasket 7 are correspondingly fitted into the thickened section. The thickened section positioning groove 12 is fitted inside the lower positioning sleeve 2. The solidified integrated sleeve 5 is composed of an outer rubber sleeve 10, a reinforcing steel wire core 13, and an outer sealing rubber 14. Several sets of reinforcing steel wire cores 13 are provided, and the inner ends of the several sets of reinforcing steel wire cores 13 are fixed on the outer rubber sleeve 10. The outer sealing rubber 14 covers the outer side of the reinforcing steel wire core 13. The outer rubber sleeves 10 in the upper positioning sleeve 1 and the lower positioning sleeve 2 are respectively tightly attached to the upper and lower sides of the outer rubber sleeve 10 in the solidified integrated sleeve 5.

[0020] The above describes the components and corresponding connection and positional relationships of the positioning sleeve and the solidified integral sleeve 5, as shown in the attached diagram. Figure 4 .

[0021] In practical applications, the first step is to select appropriate specifications for the upper positioning sleeve 1, lower positioning sleeve 2, and integrated sleeve 5 based on the actual dimensions of the water supply and drainage pipes. The integrated sleeve 5 is then fitted onto the corresponding pre-drilled hole in the pipe penetrating the roof, ensuring its centered and stable position. Next, the upper and lower positioning sleeves are fitted onto the upper and lower ends of the integrated sleeve 5, respectively, over the pipes penetrating the roof. During installation, long-lasting waterproof lubricant, adhesive, or other substances can be applied between the inner sleeve and the pipe penetrating the roof to ensure a tight fit between their symmetrical structures. The integrated outer rubber sleeve 10 and the thickened sleeve section 11 provide stable support for subsequent installation.

[0022] When installing the upper waterproof sealing plate 3, the extra-large perforated diameter circular rigid plate 6 and the facing rubber gasket 7 are tightly bonded together. Because the two are close in size, the sealing effect can be better guaranteed. Through the staggered openings on the extra-large perforated diameter circular rigid plate 6 and the near-perforated diameter circular rigid plate 8, they can be easily fitted into the thickened section positioning groove 12 of the upper positioning sleeve 1, so that the facing rubber gasket 7 is in close contact with the sleeve, effectively preventing liquid leakage from the top. Similarly, for the lower leak-proof sealing plate 4, after the circular rigid plate 8 with a near-perforation diameter and the facing rubber gasket 7 are attached together, it is placed in the thickened section positioning groove 12 of the lower positioning sleeve 2 to achieve a tight seal at the bottom. During the installation process, corresponding sealing materials, such as asphalt or concrete, need to be put between the upper waterproof sealing plate 3, the lower leak-proof sealing plate 4, the solidified integrated sleeve 5, and the perforation position. After the materials solidify, other waterproof materials are applied and sealed to the contact surfaces between the extra-large perforation diameter circular rigid plate 6, the facing rubber gasket 7, the near-perforation diameter circular rigid plate 8 and the wall and wall surface to achieve a better sealing effect.

[0023] The reinforcing steel wire core 13 inside the solidified integrated sleeve 5 enhances the structural strength relative to the solidified material in the gap. Several sets of reinforcing steel wire cores are fixed at their inner ends to the outer rubber sleeve, and the outer sealing rubber covers the outside of the reinforcing steel wire cores. This not only further enhances the sealing performance but also resists pipeline vibration and external forces. In actual use, when the pipeline vibrates due to water flow impact or other factors, this sealing and protective structure, with its integrity and stability, can effectively prevent excessive pipeline displacement, thus maintaining a good sealing state for a long time.

[0024] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
