Description

Technical Field

[0001] This application relates to the field of roof expansion joint technology, and in particular to a roof expansion joint connection structure. Background Technology

[0002] The roof is the building's external envelope, and its design follows the principles of "ensuring functionality, rational construction, combining waterproofing and drainage, selecting superior materials, and ensuring aesthetics and durability." Good drainage and preventing water intrusion into the building are among the roof's primary functions. Expansion joints are the weakest link in roof waterproofing; therefore, properly waterproofing these joints is crucial for the building's use and daily maintenance. Expansion joints are a general term encompassing expansion joints, settlement joints, and seismic joints. Buildings often deform under external forces, leading to cracking and even damage. Expansion joints are structural joints designed to address this situation.

[0003] During existing expansion joint construction, a V-shaped or U-shaped groove should be reserved at the expansion joint of the waterproof membrane, filled with elastic padding material to prevent the waterproof membrane from tearing due to structural deformation. The termination of the waterproof membrane needs to be fixed to the top of the flashing wall and covered with a metal cover plate, leaving a drainage gap between the cover plate and the membrane. However, in daily use, there is a risk that the metal cover plate may deform or even break when stepped on, which can not only cause water leakage, but also, in more serious cases, lead to accidents where people fall. Summary of the Invention

[0018] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Various examples are provided by way of explanation and not by way of limitation. In fact, those skilled in the art will understand that modifications and variations can be made to the present application without departing from the scope or spirit of the present application. For example, a feature shown or described as part of one embodiment may be used in another embodiment to produce yet another embodiment. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention should fall within the scope of protection of the embodiments of the present invention.

[0019] In one embodiment of this application, such as Figures 1-5 As shown, a roof expansion joint 2 connection structure is disclosed. The expansion joint 2 applied to the roof 1 includes a step 4, an outer cover plate 6, an inner support component 7, an inner insulation layer 3, and a waterproof membrane. The inner insulation layer 3 is laid on the side walls and top surface of the roof 1; the inner insulation layer 3 mainly plays a role in heat preservation of the building and prevents the outdoor temperature from affecting the indoor temperature.

[0020] The waterproof membrane is laid on the upper part of the sidewalls and the top surface of the roof 1, and is located on the outside of the inner insulation layer 3. The waterproof membrane includes a first waterproof membrane 8 and a second waterproof membrane 9. The first waterproof membrane 8 is laid on the upper part of the sidewalls and the top surface of the roof 1, and is recessed inward at the position corresponding to the expansion joint 2; The second waterproof membrane 9 is laid on the outside of the first waterproof membrane 8, with an inward groove corresponding to the expansion joint 2. A waterproof filler 10 is placed between the second waterproof membrane 9 and the first waterproof membrane 8, positioned at the corresponding recess. The second waterproof membrane 9, the first waterproof membrane 8, and the inner insulation layer 3 are fixed to the side wall of the roof 1 by rivets 11 passing through them sequentially from the outside in. The waterproof filler 10 includes asphalt-impregnated hemp fibers, soft foamed polyethylene strips, or a mixture of both. The first waterproof membrane 8 and the second waterproof membrane 9 provide dual waterproofing, with the asphalt-impregnated hemp fibers primarily serving as waterproofing, corrosion protection, and joint filling. The soft foamed polyethylene strips primarily fill gaps, provide waterproofing, and also cushion and reduce vibration, thus lowering noise. Therefore, the mixture not only fills gaps and provides a third layer of waterproofing but also offers corrosion protection and noise reduction.

[0021] Two steps 4 are provided, one on each side of the roof 1. Each step 4 has a mounting base 5 at its top, extending along its length. The step 4 design reduces the height of the outer cover plate 6 from the roof 1, preventing excessive support height at the bottom of the cover plate 6 and ensuring its structural strength. The steps 4 are constructed of brick and concrete, resulting in low construction costs and a long service life. The steps also facilitate worker access and facilitate future maintenance and construction. The mounting base 5 is primarily used to secure the outer cover plate 6. The mounting base 5 is stepped, facilitating a tight seal, and is made of cement or metal strips.

[0022] The outer cover plate 6 is arched, with its width sides vertically downwards. It is positioned directly above the roof 1, covering the expansion joint 2. The lower parts of both sides of the outer cover plate 6 are stepped, fitting together with the two mounting seats 5 to form a sealing structure. The outer cover plate 6 is located inside the two mounting seats 5 and is fixed with bolts. The outer cover plate 6 is made of aluminum alloy plate with a thickness of 1-2 cm. The outer sides of the steps 4 and the outer cover plate 6 are coated with waterproof mortar 12. The waterproof mortar 12 has excellent flexibility, can seal small cracks, has strong resistance to seepage pressure, and exhibits excellent water repellency on both the water-facing and water-repellent sides. It is quick and easy to apply, improving the waterproof performance of the steps 4 and the outer cover plate 6.

[0023] The inner support component 7 is disposed inside the outer cover plate 6. The upper part of the inner support component 7 is attached to the inner surface of the outer cover plate 6 and provides support and reinforcement to the outer cover plate 6. The length of the inner support component 7 is the same as the length of the outer cover plate 6. The inner support component 7 includes a waterproof support plate 701, a support upright plate 702, and a diagonal brace 703.

[0024] The supporting waterproof plate 701 is horizontally positioned, and its upper surface is in contact with the inner surface of the outer cover plate 6. The upper surface of the supporting waterproof plate 701 can be either flat or curved, depending on the application; in this embodiment, a flat surface is used. Several water-guiding grooves 704 are formed on the upper surface of the supporting waterproof plate 701. The cross-section of each water-guiding groove 704 is semi-circular or V-shaped to facilitate water flow convergence; in this embodiment, a semi-circular cross-section is used. The water-guiding grooves 704 are arranged along the length of the supporting waterproof plate 701, and are parallel to each other. Connecting holes 705 are provided between adjacent water-guiding grooves 704. When the outer cover plate 6 cracks or deforms and leaks water, the supporting waterproof plate 701 can provide initial waterproofing, while simultaneously guiding the water flow to other locations through the water-guiding grooves 704. Multiple connecting holes 705 are evenly spaced along the length of the water-guiding grooves 704. The connecting hole 705 facilitates the interconnection and convergence of water flow between adjacent water guide channels 704. When one water guide channel 704 becomes blocked and drainage is impaired, water can be discharged from other water guide channels 704. Several water guide ribs 706 are provided along the length of the channel wall of the water guide channel 704. These ribs guide the water flow and reduce stagnation. Several filter screens 707 are evenly spaced inside the water guide channel 704. The filter screens primarily filter solid particles in the water guide channel 704, preventing solid particles from flowing into and accumulating on the waterproof membrane, which could ultimately create a weight burden on the recessed areas of the waterproof membrane or block drainage.

[0025] There are two support plates 702. Both support plates 702 are welded to the support waterproof plate 701. The two support plates 702 are respectively set on the roof 1 on both sides of the expansion joint 2. The support plates 702 are connected to the roof 1 by bolts.

[0026] Multiple diagonal braces 703 are provided, with two diagonal braces 703 forming a group. One end of each pair of diagonal braces 703 in each group is connected to a supporting upright plate 702, and the other end is connected to the center of the lower surface of the waterproof supporting plate 701, thus providing central reinforcement. One end of each diagonal brace 703 is connected to the inner side of one of the supporting upright plates 702, and the other end is connected to the center of the lower surface of the waterproof supporting plate 701. The diagonal braces 703 are welded to the supporting upright plates 702 and the waterproof supporting plate 701.

[0027] The working process and principle of the above structure are as follows: The inner insulation layer and waterproof membrane are laid sequentially on the side walls and top surface of the roof 1 and fixed with rivets 11. Then, the steps 4 provide external protection and support. The outer cover plate 6 is then fixed to the steps 4 with mounting bases 5. The arched structure of the outer cover plate 6 disperses the load stress, enhances symmetry, and converts the load more evenly into axial pressure, significantly reducing bending moment and shear force, improving the load-bearing capacity of the outer cover plate 6, and preventing stress deformation or cracking. An inner support component 7 is installed below the outer cover plate 6 to support it. The combined design of the outer cover plate 6 and the inner support component 7 enhances the outer cover plate 6's resistance to deformation under foot traffic, improves its load-bearing capacity, extends its service life, and prevents cracking that could lead to leaks or falls. This also strengthens the protection of the waterproof membrane. When the outer cover plate 6 cracks or deforms and leaks, the supporting waterproof membrane 701 provides initial waterproofing. Simultaneously, the water flow is guided to other areas via the water guide channel 704. The connecting hole 705 facilitates the flow of water between adjacent water guide channels 704. If one water guide channel 704 becomes blocked, water can be discharged from other water guide channels 704. Several water guide ribs 706 are arranged along the length of the water guide channel 704 to guide the water flow and reduce stagnation. Several filter screens 707 are evenly spaced inside the water guide channel 704. The filter screen is mainly used to filter solid particles in the water channel 704, preventing solid particles from flowing into the waterproof membrane and accumulating, which would eventually create a weight burden on the recessed parts of the waterproof membrane or block drainage.

[0028] In another embodiment of this application, such as Figure 1 and Figure 6 As shown, a roof expansion joint 2 connection structure is disclosed. The expansion joint 2 applied to the roof 1 includes a step 4, an outer cover plate 6, an inner support component 7, an inner insulation layer 3, and a waterproof membrane. The inner insulation layer 3 is laid on the side walls and top surface of the roof 1; the inner insulation layer 3 mainly plays a role in heat preservation of the building and prevents the outdoor temperature from affecting the indoor temperature.

[0029] The waterproof membrane is laid on the upper part of the sidewalls and the top surface of the roof 1, and is located on the outside of the inner insulation layer 3. The waterproof membrane includes a first waterproof membrane 8 and a second waterproof membrane 9. The first waterproof membrane 8 is laid on the upper part of the sidewalls and the top surface of the roof 1, and is recessed inward at the position corresponding to the expansion joint 2; The second waterproof membrane 9 is laid on the outside of the first waterproof membrane 8, with an inward groove corresponding to the expansion joint 2. A waterproof filler 10 is placed between the second waterproof membrane 9 and the first waterproof membrane 8, positioned at the corresponding recess. The second waterproof membrane 9, the first waterproof membrane 8, and the inner insulation layer 3 are fixed to the side wall of the roof 1 by rivets 11 passing through them sequentially from the outside in. The waterproof filler 10 includes asphalt-impregnated hemp fibers, soft foamed polyethylene strips, or a mixture of both. The first waterproof membrane 8 and the second waterproof membrane 9 provide dual waterproofing, with the asphalt-impregnated hemp fibers primarily serving as waterproofing, corrosion protection, and joint filling. The soft foamed polyethylene strips primarily fill gaps, provide waterproofing, and also cushion and reduce vibration, thus lowering noise. Therefore, the mixture not only fills gaps and provides a third layer of waterproofing but also offers corrosion protection and noise reduction.

[0030] Two steps 4 are provided, one on each side of the roof 1. Each step 4 has a mounting base 5 at its top, extending along its length. The step 4 design reduces the height of the outer cover plate 6 from the roof 1, preventing excessive support height at the bottom of the cover plate 6 and ensuring its structural strength. The steps 4 are constructed of brick and concrete, resulting in low construction costs and a long service life. The steps also facilitate worker access and facilitate future maintenance and construction. The mounting base 5 is primarily used to secure the outer cover plate 6. The mounting base 5 is stepped, facilitating a tight seal, and is made of cement or metal strips.

[0031] The outer cover plate 6 is arched, with its width sides vertically downwards. It is positioned directly above the roof 1, covering the expansion joint 2. The lower parts of both sides of the outer cover plate 6 are stepped, fitting together with the two mounting seats 5 to form a sealing structure. The outer cover plate 6 is located inside the two mounting seats 5 and is fixed with bolts. The outer cover plate 6 is made of aluminum alloy plate with a thickness of 1-2 cm. The outer sides of the steps 4 and the outer cover plate 6 are coated with waterproof mortar 12. The waterproof mortar 12 has excellent flexibility, can seal small cracks, has strong resistance to seepage pressure, and exhibits excellent water repellency on both the water-facing and water-repellent sides. It is quick and easy to apply, improving the waterproof performance of the steps 4 and the outer cover plate 6.

[0032] The inner support component 7 is located inside the outer cover plate 6. The upper part of the inner support component 7 is attached to the inner surface of the outer cover plate 6, providing support and reinforcement. The length of the inner support component 7 is the same as the length of the outer cover plate 6. The inner support component 7 is a honeycomb panel, and its upper part is shape-fitted and tightly fitted to the outer cover plate 6. The honeycomb panel is an integrated support structure, providing higher support strength and lighter weight. It also allows for a tighter fit with the outer cover plate 6, resulting in more stable support. The honeycomb panel also has higher strength.
