Description

Technical Field

[0001] This application relates to the technical field of building engineering, and in particular to a socket-type waterproofing plate structure. Background Technology

[0002] Waterproofing the window sills of exterior windows is a crucial aspect of ensuring the durability of the building envelope. Currently, there are two main methods for installing window sill waterproofing boards: one is to directly fix them to the window frame with screws and fill the joints with sealant; the other is to use an integrated snap-fit ​​structure, where the protrusions or grooves on the window frame directly engage with the slots or hooks of the waterproofing board to achieve a connection.

[0003] However, the aforementioned existing technologies have significant drawbacks. Screw fixing requires drilling into the window frame, compromising its integrity, weakening structural strength, and creating new seepage channels. The sealant is prone to aging and cracking under long-term exposure to sunlight, rain, and temperature cycles, leading to waterproofing failure and high maintenance costs. While the integrated snap-fit ​​structure avoids drilling damage, the rigid connection between the waterproofing plate and the window frame makes it difficult to compensate for construction errors during on-site installation. Furthermore, if the waterproofing plate is damaged, the entire plate must be removed and replaced, making individual maintenance impossible. In addition, the stress generated by wind loads and temperature deformation on the waterproofing plate is directly transferred to the window frame connection points, which can easily damage the window frame over time.

[0004] Therefore, there is an urgent need for a new type of window sill drip edge connection structure that can protect the integrity of the window frame while achieving a stable connection and maintainability of the drip edge. Summary of the Invention

[0005] To ensure the integrity of the window frame while achieving a stable connection and maintainability of the waterproofing plate.

[0006] This application provides a socket-type drip edge structure, which adopts the following technical solution: A socket-type waterproofing plate structure, comprising: The socket is used to fix it to the window frame; The connector includes a snap-fit ​​groove and a mating strip connected together, wherein the snap-fit ​​groove is for the socket to be inserted into; A water-spraying plate includes a guide plate body, one end of which is integrally formed with a connecting groove for engaging with the mating clip; Fasteners are used to connect the mating clip and the connecting groove.

[0007] By adopting the above technical solution, during installation, the socket is first fixed to the lower edge of the window frame. Then, the fastening groove of the connector is aligned with the socket and inserted to achieve a socket-type connection between the window frame and the connector. Subsequently, the connecting groove of the drip edge plate is aligned with the mating strip of the connector and engaged, so that the mating strip engages with the connecting groove. Finally, the mating strip and the connecting groove are fastened together with fasteners, forming an integral load-bearing structure with the drip edge plate and the window frame. The socket-locking fit between the socket and the fastening groove connects the window frame and the connector. The engagement of the mating strip with the connecting groove enables the connector to mate with the drip edge plate. Finally, the fasteners further lock the connector and the drip edge plate in place. The traditional destructive drilling connection method for window frames is transformed into a non-destructive socket connection, which not only protects the structural integrity of the window frame, but also enables the detachable replacement of the drip edge plate through the intermediary role of the connector. At the same time, the rigid connection of the fasteners ensures the connection reliability of the drip edge plate under wind load, thus solving the technical defects of the existing technology where the drip edge plate is directly connected to the window frame and cannot be adjusted or replaced.

[0008] Optionally, the mating strip includes snap-fit ​​ribs and connecting plates spaced apart in the vertical direction, and a side rib is provided between the snap-fit ​​ribs and the connecting plate; The fastener includes a threaded rod that passes through the snap-fit ​​rib along the connecting groove and is threadedly engaged with the connecting plate.

[0009] By adopting the above technical solution, the locking ribs and connecting plates of the mating strip are arranged at intervals in the vertical direction. The two are connected by side ribs to form a U-shaped cross-section structure, which improves the bending stiffness and torsional performance of the mating strip. During installation, the threaded rod passes through the through hole on the locking rib and the threaded hole on the connecting plate from the outside of the connecting groove. The threaded rod is rotated to form a threaded engagement with the connecting plate. As the threaded rod is screwed in, the locking rib and the connecting plate move closer to each other and clamp the side wall of the connecting groove, realizing the rigid locking of the mating strip and the connecting groove.

[0010] Optionally, the end of the guide plate away from the connecting groove is provided with a water-gathering protrusion, which is gradually tapered downwards.

[0011] By adopting the above technical solution, the downward tapering of the water-collecting protrusion allows rainwater flowing along the surface of the waterproofing board to converge at the end and drip down, thus avoiding pollution and leakage caused by rainwater flowing along the bottom of the board to the wall.

[0012] Optionally, the bottom of the guide plate is provided with a drip edge, which is located near the water-gathering protrusion, and one end of the drip edge extends downward and then bends toward the connecting groove.

[0013] By adopting the above technical solution, when rainwater flows back along the bottom of the guide plate towards the window frame due to wind or capillary action, it is first blocked by the downward extension of the drip edge, and then encounters the guide edge that bends inward. The rainwater is forcibly cut off and drips before reaching the edge of the guide plate, and cannot continue to penetrate towards the window frame.

[0014] Optionally, an auxiliary support plate is also provided at the bottom of the guide plate body, with one end of the auxiliary support plate inclined toward the direction close to the connecting groove body.

[0015] By adopting the above technical solution, when the plasterboard is subjected to downward wind or snow loads, the inclined end of the auxiliary support plate abuts against the surface of the wall where the window frame is located, forming a fulcrum and transferring part of the load to the wall where the window frame is located through the auxiliary support plate; the auxiliary support plate, the guide plate, and the wall form a stable triangular force-bearing structure, transferring the load in the middle and end of the plasterboard to the wall, dispersing the stress on the connectors, and improving the wind pressure resistance and long-term stability of the overall structure.

[0016] Optionally, the guide plate is inclined downward relative to the window frame, and the inclination angle of the guide plate is 3-5°.

[0017] By adopting the above technical solution, the drainage slope is optimized. After rainwater falls on the guide plate, it flows downward naturally. The tilt angle ensures that the water flow speed is moderate, so that it will not stagnate or be over-washed, thus achieving efficient drainage.

[0018] Optionally, the connector further includes a heat insulation strip, which includes a heat insulation shell and heat insulation material filled within the heat insulation shell; The thermal insulation strip is disposed between the fastening groove and the mating strip to separate the connecting groove and the window frame.

[0019] By adopting the above technical solution, when the outdoor low temperature is transferred to the mating strip through the waterproofing plate, it first encounters the thermal insulation strip set between the fastening groove and the mating strip. The thermal insulation strip forms an efficient thermal resistance barrier through the thermal insulation shell and the internal filling material, cutting off the heat conduction path from the waterproofing plate through the connector to the window frame, making it difficult for heat to be conducted from the waterproofing plate side to the window frame side. This significantly reduces the thermal bridging effect at the lower edge of the window frame, making the inner surface temperature of the window frame higher than the indoor dew point temperature, improving the condensation problem in winter, preventing condensate from accumulating at the joints, and reducing the risk of corrosion.

[0020] Optionally, the connecting plate is provided with a group of drainage holes.

[0021] By adopting the above technical solution, when condensate accumulates in the cavity formed by the matching strip and the connecting groove, the drainage hole group acts as a drainage channel to guide the water out of the cavity, preventing the potential for corrosion, freezing expansion, or fastener damage caused by water accumulation in the cavity.

[0022] Optionally, the fastening groove includes a fastening base and a fastening pressure plate, with one side of the fastening pressure plate rotatably connected to the fastening base; An elastic force-applying component is provided between the fastening base and the fastening pressure plate. The elastic force-applying component is used to drive the fastening pressure plate to rotate toward the fastening base to press against the socket.

[0023] By adopting the above technical solution, when the water-applying plate is subjected to downward pressure, the downward pressure is transmitted to the socket part through the connector, causing the socket part to deform downward. At this time, the fastening plate undergoes adaptive deflection under the action of the elastic force-applying component, and the fastening plate presses down synchronously with the downward movement of the socket part, forming a floating clamping state. This avoids plastic deformation or brittle fracture of the socket part caused by stress concentration at the root. During the process of bearing and unloading the load, the elastic deformation of the elastic force-applying component absorbs and releases the impact energy, preventing fatigue damage to the socket part under dynamic load.

[0024] Optionally, the socket portion is provided with an anti-collision groove, the opening of which faces the fastening pressure plate.

[0025] By adopting the above technical solution, the anti-collision groove provides clearance for the deflection movement of the fastening plate, so that the fastening plate can deflect smoothly when the water plate is subjected to downward pressure without rigidly interfering with the socket and causing damage to the socket.

[0026] In summary, this application includes at least one of the following beneficial effects: 1. This application achieves a non-destructive connection between the waterproofing plate and the window frame through a combination design of the socket, connector, waterproofing plate and fastener, avoiding drilling holes in the window frame, thereby protecting the integrity and structural strength of the window frame and reducing the risk of water leakage; 2. In this application, the water-gathering protrusion at the end of the guide plate and its downward tapering design effectively concentrate and guide rainwater, prevent water flow diffusion or backflow, improve the drainage efficiency of the waterproofing plate, reduce water stain accumulation and potential leakage problems, and enhance waterproof performance. 3. The fastening groove in this application includes a rotatably connected fastening base and a fastening pressure plate, and an elastic force-applying component is provided between the fastening base and the fastening pressure plate. When the water-applying plate is subjected to abnormal downward pressure, it will force the fastening pressure plate to make a slight elastic upward deflection. This process can absorb some energy and play a buffering role, which can effectively prevent irreversible plastic deformation or damage to the connector or window frame under extreme loads, providing important overload protection for the entire system and improving durability and safety.

[0028] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0029] Example 1

[0030] This embodiment provides a socket-type waterproofing plate structure.

[0031] refer to Figure 1 and Figure 2 The socket-type drip edge structure includes a socket part 1, a connector, a drip edge 4, and fasteners 5. The socket part 1 is a hook-shaped component formed integrally on the lower edge of the window frame 9 by extrusion of alloy profiles. The connector can be formed from sheet metal and includes an integrally connected snap-fit ​​groove 2 and a mating strip 3. The snap-fit ​​groove 2 is a groove structure with side openings. The inner wall contour of the snap-fit ​​groove 2 matches the hook contour of the socket part 1, allowing the socket part 1 to be inserted along the side. The mating strip 3 includes snap-fit ​​ribs 31 and connecting plates 32 spaced vertically. The snap-fit ​​ribs 31 and the connecting plates 32 are connected by side ribs 33 on both sides. The snap-fit ​​ribs 31 have through holes, and the connecting plates 32 have corresponding threaded holes. The number of through holes on the snap-fit ​​ribs 31 and the number of threaded holes on the connecting plates 32 are the same, and they are aligned one-to-one.

[0032] refer to Figure 1 and Figure 2The drainage plate 4 is made of metal and includes a guide plate body 41, a connecting groove 42, and a drip edge 43. The connecting groove 42 is integrally formed on the end of the guide plate body 41 near the window frame 9, and the connecting groove 42 is open and facing downwards. The shape of the connecting groove 42 matches the mating clip 3 of the connector, allowing the mating clip 3 to be inserted. A water-gathering protrusion 411 is integrally formed on the end of the guide plate body 41 away from the connecting groove 42. The cross-section of the water-gathering protrusion 411 is arc-shaped and gradually tapers downwards to form a drainage constriction. The top surfaces of the guide plate body 41 and the connecting groove 42 are coplanar, and the guide plate body 41 extends downwards at an angle away from the window frame 9, forming a smooth drainage slope. The inclination range of the guide plate body 41 is 3-5°, which ensures drainage efficiency without excessively affecting the appearance. In this embodiment, the specific inclination angle of the guide plate body 41 is 4°.

[0033] To optimize drainage and prevent rainwater from flowing back along the bottom surface of the guide plate 41, a drip edge 43 is fixedly connected to the bottom wall of the guide plate 41 near the water-collecting protrusion 411. The drip edge 43 extends downwards and then bends at approximately a 90-degree angle towards the connecting groove 42. Additionally, an auxiliary support plate 6 is welded and fixed to the bottom of the guide plate 41. The auxiliary support plate 6 extends downwards from the bottom of the guide plate 41 and is inclined at approximately 30° towards the connecting groove 42. During actual installation, the inclined end of the auxiliary support plate 6 is used to abut against the wall surface below the window frame 9. In this embodiment, two auxiliary support plates 6 are spaced apart between the connecting groove 42 and the drip edge 43.

[0034] Fastener 5 can be a self-tapping screw. The self-tapping screw includes a threaded shank. During installation, the threaded shank of the self-tapping screw passes sequentially through the side wall of the connecting groove 42 and the through hole on the retaining rib 31, then screws into the threaded hole on the connecting plate 32 and tightens. In this embodiment, multiple fasteners 5 are connected at intervals on the water-absorbing plate 4.

[0035] The implementation principle of Embodiment 1 of this application is as follows: During installation, firstly, align the fastening groove 2 of the connector with the hook of the socket 1, and insert the socket 1 into the fastening groove 2 to complete the initial non-destructive connection between the connector and the window frame 9. Next, align the connecting groove 42 of the drain plate 4 with the mating strip 3 of the connector, and press the drain plate 4 vertically so that the mating strip 3 is fully engaged in the connecting groove 42. Finally, pass the fastener 5 through the connecting groove 42 sequentially through the snap-fit ​​rib 31 and the connecting plate 32, and tighten it, so that the snap-fit ​​rib 31 and the connecting plate 32 move closer together under the tension of the threaded rod, tightly clamping the inner wall of the connecting groove 42, thereby achieving a rigid lock between the drain plate 4 and the connector. During installation, ensure that the drain plate 4 is tilted downward relative to the window frame 9, with the tilt angle controlled at about 4°. The entire process does not require construction on the main body of the window frame 9, greatly protecting the integrity of the window frame 9, simplifying the installation, and establishing a reliable physical drainage barrier. Finally, apply a layer of waterproof adhesive to the joint between the window frame 9 and the waterproofing board 4 to cover the joint and prevent rainwater from seeping into the inside of the window frame 9 along the joint.

[0036] After rainwater falls onto the surface of the waterproofing board 4, it flows towards the outside along the inclined guide plate 41 under the action of gravity. When it reaches the water-gathering protrusion 411 at the end, it is collected and drips off more rapidly. Even if a small amount of rainwater flows back along the bottom of the board due to wind or capillary action, it will be blocked by the drip edge 43 and cut off at the bend of the drip edge 43, effectively preventing rainwater from flowing back to the connection between the window frame 9 and the wall. When the waterproofing board 4 is subjected to downward loads such as wind pressure and snow load, the load is transferred to the socket 1 and the window frame 9 through the connector. At the same time, the inclined end of the auxiliary support plate 6 abuts against the wall surface, forming a stable triangular support structure, which directly transfers part of the load to the wall, significantly dispersing the force at the connection point and improving the overall structural stability and wind pressure resistance. This embodiment achieves non-destructive, stable, and adjustable installation of the waterproofing board 4, with smooth drainage and reliable waterproofing.

[0037] Example 2

[0038] The difference between this embodiment and Embodiment 1 is that: refer to Figure 3 and Figure 4 In this embodiment, the connector also includes a thermal insulation strip 7. This thermal insulation strip 7 is fixed between the fastening groove 2 and the mating clip 3, and includes a thermal insulation shell 71 made of alloy material, and thermal insulation material 72 filled within the thermal insulation shell 71. The thermal insulation material 72 is selected from closed-cell polyurethane foam. In this embodiment, the thermal insulation strip 7 is welded and fixed between the fastening groove 2 and the mating clip 3. This physically isolates the direct heat conduction path between the waterproofing plate 4 and the window frame 9. In other embodiments, snap-fit ​​structures can be machined on both sides of the thermal insulation strip 7 for fixed connection with the fastening groove 2 and the mating clip 3.

[0039] A set of drainage holes is provided on the connecting plate 32 of the mating strip 3; the set of drainage holes includes a plurality of drainage holes 321 spaced apart along the length of the connecting plate 32. The set of drainage holes can be used to promptly drain condensate or rainwater that may seep into the cavity between the mating strip 3 and the connecting groove 42 to the outside of the cavity.

[0040] In this embodiment, the fastening groove 2 specifically includes a fastening base 21 and a movable fastening pressure plate 22. One end of the fastening pressure plate 22 is rotatably connected to the fastening base 21 via a pivot. An elastic force-applying element 8 is connected between the fastening base 21 and the fastening pressure plate 22. In this embodiment, the elastic force-applying element 8 is specifically configured as a pre-tension spring fixedly connected between the fastening base 21 and the fastening pressure plate 22. The pre-tension spring always provides a torque that causes the fastening pressure plate 22 to rotate towards the fastening base 21, so that after the socket 1 is inserted, it can be tightly pressed onto the fastening base 21. In other embodiments, the elastic force-applying element 8 may also be a torsion spring sleeved on the pivot.

[0041] On the inner surface of the hook portion of the socket portion 1, an anti-collision groove 11 extending along its own length direction is provided. The opening of the anti-collision groove 11 is directly opposite to the fastening pressure plate 22, providing clearance space for the slight elastic deflection that may occur when the fastening pressure plate 22 is pressed, and avoiding rigid collision.

[0042] The implementation principle of Embodiment 2 of this application is as follows: This embodiment adds heat insulation, drainage, and dynamic buffering functions. The heat insulation strip 7 effectively blocks heat conduction from the condensate drain plate 4 to the window frame 9, significantly reducing the thermal bridging effect at the windowsill and improving indoor condensation. The drainage hole group on the connecting plate 32 ensures that even if a small amount of water vapor enters the closed cavity, it can be discharged in time, preventing internal corrosion or frost damage. When the condensate drain plate 4 is subjected to an abnormally large downward impact load, the downward impact load is transmitted to the socket 1 through the connector, and the socket 1 tends to move slightly downward. At this time, the locking plate 22, under the constant clamping force provided by the torsion spring, will generate an adaptive elastic deflection. On the one hand, it continues to press the socket 1 tightly to prevent loosening, and on the other hand, it absorbs the impact energy through its own elastic deformation, forming an overload protection mechanism to protect the connection point of the window frame 9 from damage. The anti-collision groove 11 ensures that this buffering process is carried out smoothly and avoids local stress concentration. This embodiment, while achieving basic functions, further improves the product's energy efficiency, durability, and safety.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
