Technical Field
[0001] This utility model relates to the field of building accessories technology, and in particular to a waterproof structure for building connection parts. Background Technology
[0002] Buildings typically include masonry buildings and prefabricated buildings. Due to the long construction cycle of masonry buildings, prefabricated buildings are widely used in existing technologies.
[0003] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories are processed and manufactured in factories, transported to the construction site, and assembled on-site using reliable connection methods. Prefabricated buildings mainly include precast concrete structures, steel structures, and modern wood structures.
[0004] Prefabricated buildings have a short construction cycle; however, they require waterproof structures at the two connecting components to prevent water seepage. Existing technologies use rubber rings to seal the two components, but these rings are prone to failure over long-term use.
[0005] Therefore, existing building joints suffer from poor waterproofing performance. Utility Model Content
[0006] This utility model provides a waterproof structure for building connection parts, which solves the technical problem of poor waterproof performance at building connection parts in the prior art.
[0007] Some implementation schemes for solving the above-mentioned technical problems include:

[0009] The waterproof component includes a water guide and a seal installed on the water guide;
[0010] The water guide includes an upper guide plate located inside the upper building component, a lower guide plate located outside the lower building component, and a connecting plate located between the upper building component and the lower building component. The lower end of the upper guide plate is connected to the upper end of the lower guide plate through the connecting plate.
[0011] The sealer includes a plate body installed on the lower guide plate, the plate body extending to the upper building component, and a sealing rib provided between the plate body and the upper building component in a horizontal direction. There are at least two sealing ribs, all of which are distributed in a vertical direction and are in contact with the upper building component.
[0012] A drainage groove is provided inside the plate, and a drainage outlet is provided on the side of the plate near the upper building component. Water above the sealing edge enters the drainage groove through the drainage outlet.
[0013] Preferably, the upper surface of the sealing rib is inclined, and the height of the end of the upper surface that contacts the upper building component is higher than the height of the end of the upper surface that contacts the inner wall of the drainage channel.
[0014] Preferably, the sealing ridge has four ridges, and the surface of the sealing ridge that contacts the upper building component is provided with a rubber layer, a portion of which extends to the upper surface.
[0015] Preferably, a sealing head is provided at the upper end of the plate, and the sealing head has a triangular cross-sectional shape.
[0016] Preferably, the sealing head and the plate are an integral structure, and the sealing head and the upper building component are in surface contact.
[0017] Preferably, the sealing ridge is an integral structure with the plate body, and the sealing ridge is formed by bending a portion of the plate body.
[0018] Preferably, the upper guide plate and the lower guide plate are integral with the connecting plate, and the connecting plate is provided with a water guide groove.
[0019] Preferably, the water guide channel is connected to the drainage channel.
[0020] Preferably, the water guide channel communicates with the drainage channel through an opening provided on the plate.

[0022] Compared with the prior art, the present invention has the following advantages:
[0023] 1. By setting up a water guide, the upper guide plate of the water guide is located inside the upper building component, and the lower guide plate of the water guide is located outside the lower building component. The connection of the water guide is located between the upper building component and the lower building component. Due to the setting of the upper guide plate, water will not move upward along the upper guide plate under the action of gravity, thus making the water guide have a better waterproof effect and preventing water from easily entering the building.
[0024] 2. By setting a seal, which includes a sealing ridge that contacts the upper building component, the sealing ridge can prevent water from entering between the upper and lower building components, thus further optimizing the waterproof performance of the building connection.
[0025] 3. By setting up drainage channels, the water blocked by the sealing edge can be discharged in time. In addition, the drainage channels can be set at a position away from the connecting plate, so that water is not easy to enter between the upper and lower building components, thus optimizing the waterproof performance of the building connection.

[0039] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.
[0040] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.
[0041] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0042] Reference Figures 1 to 6 As shown, a waterproof structure for a building connection includes a lower building component 1 and an upper building component 2 located above the lower building component 1, with a waterproof component 3 disposed between the upper building component 2 and the lower building component 1;
[0043] The waterproof component 3 includes a water guide 31 and a seal 32 installed on the water guide 31;
[0044] The water guide 31 includes an upper guide plate 311 located inside the upper building component 2, a lower guide plate 312 located outside the lower building component 1, and a connecting plate 313 located between the upper building component 2 and the lower building component 1. The lower end of the upper guide plate 311 is connected to the upper end of the lower guide plate 312 through the connecting plate 313.
[0045] The sealer 32 includes a plate 321 mounted on the lower guide plate 312. The plate 321 extends to the upper building component 2. A sealing rib 322 is provided between the plate 321 and the upper building component 2 in a horizontal direction. There are at least two sealing ribs 322. All sealing ribs 322 are distributed in a vertical direction and all sealing ribs 322 are in contact with the upper building component 2.
[0046] A drainage groove 323 is provided inside the plate 321, and a drainage outlet 324 is provided on the side of the plate 321 near the upper building component 2. Water above the sealing ridge 322 enters the drainage groove 323 through the drainage outlet 324.
[0047] Both the water guide 31 and the seal 32 can be made of metal, and the outer sides of both the water guide 31 and the seal 32 should be coated with anti-rust paint.
[0048] The upper building component 2 and the lower building component 1 can be plate-like structures. The ends of the upper building component 2 and the lower building component 1 are typically installed inside the cast-in-place portion of the building. Therefore, a waterproof structure may not be required between the upper building component 2, the lower building component 1, and the cast-in-place portion; alternatively, a structural waterproofing method may be used. The waterproof structure disclosed in this solution is only used to disclose the waterproofing between the upper building component 2 and the lower building component 1.
[0049] The sealing ridge 322 should be in close contact with the upper building component 2; therefore, the sealing ridge 322 can have a certain degree of elasticity. Elastic layered materials such as rubber can be bonded to the sealing ridge 322 to improve waterproofing performance.
[0050] The seal 32 is used to prevent water from the outside of the upper building component 2 from entering between the upper building component 2 and the lower building component 1, thereby preventing water from entering between the upper building component 2 and the lower building component 1.
[0051] Reference Figures 1 to 6 As shown, in some embodiments, the upper surface of the sealing ridge 322 is inclined, and the height of the end of the upper surface that contacts the upper building member 2 is higher than the height of the end of the upper surface that contacts the inner wall of the drainage groove 323.
[0052] The sealing ridge 322 has four ridges, and the surface of the sealing ridge 322 that contacts the upper building component 2 is provided with a rubber layer, a portion of which extends to the upper surface.
[0053] The more sealing ribs 322 there are, the better the sealing performance. Sealing refers to the seal between the sealing ribs 322 and the upper building component 2, preventing water from flowing downwards along the outside of the upper building component 2.
[0054] In some embodiments, a sealing head 325 is provided at the upper end of the plate 321, and the sealing head 325 has a triangular cross-sectional shape.
[0055] The sealing head 325 and the plate 321 are an integral structure, and the sealing head 325 is in surface contact with the upper building component 2.
[0056] The sealing head 325 has the same function as the sealing ridge 322. Since the sealing head 325 is located at the upper end of the plate 321, the sealing head 325 can be set to a larger volume, thereby giving the sealing head 325 a larger contact area with the upper building component 2.
[0057] A rubber layer may also be provided on the sealing head 325. For example, a rubber layer may be bonded to the sealing head 325 so that the sealing head 325 contacts the upper building component 2 through the rubber layer.
[0058] Reference Figures 1 to 6 As shown, in some embodiments, the sealing ridge 322 and the plate 321 are an integral structure, and the sealing ridge 322 is formed by bending a portion of the plate 321.
[0059] In some embodiments, the upper guide plate 311 and the lower guide plate 312 are integral with the connecting plate 313, and the connecting plate 313 is provided with a water guide groove 3131.
[0060] The water guide channel 3131 communicates with the drainage channel 323. The plate 321 can be a hollow structure, with the drainage channel 323 formed by the space inside the plate 321. Ribs can also be installed inside the plate 321 to improve its strength. The ribs and the plate 321 can be an integral structure, and the ribs are arranged vertically, with the drainage channel 323 formed between adjacent ribs.
[0061] In some embodiments, the water guide channel 3131 communicates with the drainage channel 323 through the opening 326 provided on the plate 321.
[0062] The bottom surface of the opening 326 is designed to prevent water in the drainage groove 323 from flowing back to the inclined surface of the water guide groove 3131. The plate 321 is fixed to the lower guide plate 312 by screws 33. The lower guide plate 312 is provided with screw holes that cooperate with the screws 33.
[0063] The screw hole may penetrate the lower guide plate 312, or it may not penetrate the lower guide plate 312.
[0064] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.
[0065] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here.
