Description

Technical Field

[0001] This utility model relates to the field of building construction technology, especially roof waterproofing construction technology, specifically an adaptive metal roof waterproofing sleeve auxiliary structure. Background Technology

[0002] Roof waterproofing refers to a series of techniques and measures to prevent rainwater, snowmelt, or other moisture from penetrating into the interior of a building. It typically includes the installation of a waterproofing layer, the selection of waterproofing materials, and the application of construction techniques. The aim is to ensure the roof's airtightness and durability, preventing moisture damage to the building structure and interior spaces. Roof waterproofing construction requires strict adherence to regulations; pipes exiting the roof must have pre-embedded sleeves to prevent rainwater from leaking through gaps between the pipes and the roof structure. The installation of roof waterproofing membranes is carried out after the roof structure construction is completed, while pipe installation usually requires pre-reserving channels during the roof structure construction phase, hence the pre-embedded sleeves. To overcome the inherent waterproofing problems of metal roofs, enhance their waterproofing performance, protect them from corrosion and damage, improve overall roof performance, comply with building codes and standards, and offer convenience in construction and maintenance as well as economic benefits, metal roof waterproofing membranes have gradually emerged on the market.

[0003] When laying waterproof membrane on metal roofs, the common practice is to drill holes in the metal roof panel according to the design location for pre-embedded sleeves of pipes protruding from the roof, then install a waterproof base, and finally lay the waterproof layer. However, the following problems often arise during actual construction: ① The precision of the arc cutting at the pipe protrusion location on the metal roof is not high, easily leaving gaps that pose a risk of leakage; ② Using cement mortar to construct arcs or truncated cones on the metal roof results in poor performance and easy detachment. Using waterproof bases also leads to numerous joints and poor overall integrity, easily leaving a risk of leakage; ③ The sloping roof working surface has limited operating space at the base of the pre-embedded sleeves, making construction defects more likely. All of these problems result in incomplete waterproofing, low construction quality, difficulties in later maintenance and inspection, negatively impacting the user experience and hindering the promotion and application of this structure in the field of waterproofing construction technology.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] Example: Figures 1 to 3 As shown, an adaptive metal roof waterproof sleeve auxiliary structure is used to fit over a pre-embedded sleeve 2 extending outside the roof 1. Its main purpose is to prevent rainwater, snowmelt, and other substances from entering the building through the gap between the roof 1 and the pre-embedded sleeve 2, thus providing protection. In this embodiment, the waterproof sleeve auxiliary structure mainly consists of a surface-adhesive part 3, an elastic tube 4, and an expansion joint 5. The surface-adhesive part 3 is used to tightly adhere to the surface of the roof 1, forming a sealed interface to prevent moisture from seeping between the roof and the waterproof sleeve auxiliary structure. Simultaneously, the surface-adhesive part 3 covers the gap between the roof 1 and the pre-embedded sleeve 2, further ensuring that there are no gaps between the waterproof sleeve auxiliary structure and the roof, thereby preventing moisture penetration. The aforementioned elastic tube 4 is used to connect the aforementioned surface-fitting part 3 and the aforementioned expansion joint 5. The length and angle of the elastic tube 4 can be adjusted so that the surface-fitting part 3 can adapt to roofs 1 at different angles. The design of the elastic tube 4 allows it to adapt to deformation between the roof 1 and the embedded sleeve 2, while providing a certain degree of flexibility to ensure that the waterproof sleeve auxiliary structure maintains good waterproof performance under conditions of thermal expansion and contraction. The aforementioned expansion joint 5 connects the aforementioned elastic tube 4 and is used to fit over the aforementioned embedded sleeve 2. It allows the waterproof sleeve auxiliary structure to expand and contract to a certain extent, thereby adapting to the displacement of the embedded sleeve 2 or to embedded sleeves 2 of different lengths. This enhances practicality, increases utilization, and greatly improves the user experience, which is conducive to the promotion and application of the aforementioned adaptive metal roof waterproof sleeve auxiliary structure in the field of building construction technology.

[0024] In this embodiment, the waterproof sleeve auxiliary structure combines the aforementioned surface-fitting part 3, the aforementioned elastic tube 4, and the aforementioned expansion joint 5. This allows the waterproof sleeve auxiliary structure to effectively prevent rainwater, snowmelt, and other substances from entering the building through the gap between the roof 1 and the pre-embedded sleeve 2, providing reliable waterproof protection. The three components are interconnected. In this embodiment, the roof is a metal roof. Since metal roofs are prone to deformation due to thermal expansion and contraction, the waterproof sleeve auxiliary structure can effectively cope with these deformations, ensuring the effectiveness of use.

[0025] In this embodiment, to enhance the stability and reliability of the entire structure, one end of the expansion joint 5 is folded inward to form a sleeve hook 7, which is used to hook onto the opening of the pre-embedded sleeve 2. When the sleeve hook 7 is hooked onto the opening of the pre-embedded sleeve 2, the expansion joint 5 can be pulled to adjust the overall length of the waterproof sleeve auxiliary structure so that it can adapt to pre-embedded sleeves 2 of different lengths. The sleeve hook 7 can also firmly hook the waterproof sleeve auxiliary structure onto the opening of the pre-embedded sleeve 2 to prevent the waterproof sleeve auxiliary structure from shifting or falling off due to wind, vibration or other external forces during use. Since the expansion joint 5 itself has a certain degree of flexibility, the sleeve hook 7 can also adapt to the slight deformation of the pre-embedded sleeve 2 during the hooking process, further improving the adaptability and reliability of the structure.

[0026] In this embodiment, the embedded sleeve 2 is typically made of metal, which expands and contracts with temperature changes. In this embodiment, a gap is created between the sleeve hook 7 and the wall of the embedded sleeve 2. This gap allows the sleeve hook 7 to maintain a tight connection with the embedded sleeve 2 even when the sleeve 2 undergoes minor deformation, preventing damage or loosening due to excessive pressure. During use, the embedded sleeve 2 may also experience minor displacement due to mechanical vibration, wind, or other external forces. The gap absorbs these displacements, ensuring a stable connection between the sleeve hook 7 and the embedded sleeve 2. The gap also makes it easier for the sleeve hook 7 to engage with the opening of the embedded sleeve 2, reducing friction and resistance during installation and improving installation efficiency. If maintenance or replacement of the waterproof sleeve auxiliary structure is required, the gap allows for easy removal of the sleeve hook 7 from the embedded sleeve 2 without damaging it.

[0027] In this embodiment, the telescopic joint 5 is mainly composed of a first telescopic joint adjustment part 5-1 and a second telescopic joint adjustment part 5-2. The second telescopic joint adjustment part 5-2 is partially embedded in the first telescopic joint adjustment part 5-1 and the two are slidably connected to adjust the overall length of the telescopic joint 5. The sleeve hook 7 is formed on the top of the second telescopic joint adjustment part 5-2.

[0028] In this embodiment, the surface bonding part 3 is arranged in a trumpet shape. The trumpet-shaped surface bonding part 3 can better fit tightly with the surface of the roof 1, forming a sealed bonding surface 6, which effectively reduces the gaps between the roof 1 and the waterproof sleeve auxiliary structure, preventing rainwater, snowmelt, and other substances from entering the house through these gaps. The trumpet-shaped design also allows the surface bonding part 3, combined with the elastic tube 4, to adapt to roofs 1 with different slopes, ensuring a good bonding effect on various roof structures. The formation of the bonding surface 6 further improves the waterproof performance. This sealed surface form can effectively prevent water penetration, ensuring that the house is not intruded by water. The cross-sectional width of the bonding surface 6 is 3-5mm. This width is neither too large, which would make installation difficult, nor too small, which would result in a loose fit, thus ensuring good sealing performance. Moreover, the width of 3-5mm can also accommodate minor unevenness and deformation of the roof 1, ensuring a good bonding effect under various working conditions. In this embodiment, the cross-sectional width of the bonding surface 6 is preferably 3mm, which improves construction efficiency while ensuring a sealing effect.

[0029] The adaptive metal roof waterproof sleeve auxiliary structure described in this embodiment is suitable for roof 1 with a tilt angle of 10° to 45°. The tilt angle of the roof varies depending on factors such as building function, climate conditions, and drainage requirements. The tilt angle range of 10° to 45° covers most common roof structures, enabling this waterproof sleeve auxiliary structure to be widely used in different types of building projects.

[0030] To enhance the structural stability of the entire waterproof sleeve auxiliary structure, in this embodiment, the surface bonding part 3, the elastic tube 4, and the expansion joint 5 are integrally molded. This integral molding design makes the surface bonding part 3, the elastic tube 4, and the expansion joint 5 a single unit, effectively preventing loosening or separation between components and ensuring good waterproof performance during long-term use. The integral molding design reduces the number of connection points between components, thereby reducing the risk of leakage due to poor sealing or loosening at these points.

[0031] In this embodiment, the elastic tube 4 is a corrugated tube. The corrugated tube has good elasticity and flexibility, and can adapt to the thermal expansion and contraction and mechanical displacement between the roof 1 and the pre-embedded sleeve 2. Its elastic compensation mechanism ensures that the waterproof sleeve auxiliary structure can maintain good sealing performance under various working conditions. In addition, the corrugated tube can absorb the vibration caused by external forces such as wind and mechanical vibration, reduce the impact of these vibrations on the waterproof sleeve auxiliary structure, and further improve the stability and reliability of the structure.

[0032] In this embodiment, the pre-embedded sleeve 2 includes, but is not limited to, ventilation ducts and drainage ducts. The above-mentioned waterproof sleeve auxiliary structure can effectively ensure the sealing between the pipe and the roof 1.

[0033] The specific installation method of the adaptive metal roof waterproof sleeve auxiliary structure in this embodiment is as follows: First, drill holes in the roof 1 made of metal material according to the design position, grind the edges of the holes smooth, and remove burrs; then install the pre-embedded sleeve 2 at the hole; then, slide the waterproof sleeve auxiliary structure of this embodiment into the pre-embedded sleeve 2 from top to bottom, so that the sleeve hook 7 at the top of the expansion joint adjustment part 2 5-2 hangs on the pipe opening of the pre-embedded sleeve 2, fix the expansion joint adjustment part 2 5-2, and then pull the expansion joint adjustment part 1 5-1 downward to adjust the overall length of the waterproof sleeve auxiliary structure to adapt to the pre-embedded sleeve 2. The length is adjusted; then, by adjusting the elastic tube 4 (corrugated tube) of the connecting expansion joint 5 and the bottom flared surface (i.e., the surface bonding part 3) to adjust the degree of front and rear folding and shrinkage, the angle of the flared surface (i.e., the surface bonding part 3) is adjusted to be consistent with the sloping roof. Waterproof adhesive is evenly applied within 3mm of the edge of the bottom flared surface. The expansion joint adjustment part 5-1 is pulled down to make the bottom flared surface adhere firmly to the metal sloping roof. The flared surface is gently pressed down to make it adhere to the roof around its perimeter and form a smooth arc. After the waterproof adhesive is initially firmly bonded, the base layer can be cleaned and the waterproof coating can be applied in sequence, and the waterproof layer can be laid from low to high.

[0034] This embodiment presents an adaptive metal roof waterproof sleeve auxiliary structure, which includes a surface-fitting part 3, an elastic tube 4, and an expansion joint 5. The surface-fitting part 3 is designed to fit snugly against the surface of the roof 1 to prevent rainwater and other substances from entering the building through the gap between the embedded sleeve 4 and the roof 1. The length and angle of the elastic tube 4 can be adjusted to allow the surface-fitting part 3 to adapt to roofs 1 with different slopes, ensuring installation effectiveness. The expansion joint 5 allows the auxiliary structure to adapt to embedded sleeves 2 of different lengths, enhancing practicality and increasing utilization, greatly improving the user experience, and facilitating the promotion and application of the aforementioned adaptive metal roof waterproof sleeve auxiliary structure in the field of building construction technology.
