Description

Technical Field

[0002] The overhanging eaves, also known as the overhanging eaves, refers to the part of the floor that protrudes from the outer wall. Its main function is to facilitate roof drainage and protect the outer wall.

[0003] Currently, the existing cantilevered eaves are mainly made of reinforced concrete. Ceramic tiles or waterproof coatings are laid on the surface of the cantilevered eaves, but the waterproof effect is poor and it is easy to cause water leakage. When the length of the cantilevered eaves is increased, the weight of the cantilevered eaves is larger and the bearing capacity of the wall is larger. Utility Model Content

[0004] In order to improve the problem of water leakage in existing cantilevered eaves, the present application provides an aluminum plate cantilevered eaves structure.

[0005] The aluminum plate cantilevered eaves structure provided in this application adopts the following technical solutions:

[0006] An aluminum plate cantilevered eaves structure comprises a cantilevered eaves, a support frame and a waterproof board, wherein the support frame is arranged around the surface of the cantilevered eaves, one end of the support frame extends toward the cantilevering direction of the cantilevered eaves, and the end of the support frame extending outward is inclined upward; the waterproof board is detachably connected to the support frame, and adjacent waterproof boards are sealedly connected, and a profile is fixedly connected to one end of the support frame away from the cantilevered eaves, and the profile is sealedly connected to the waterproof board, and a drainage ditch is provided on the inner side of the cantilevered eaves.

[0007] By adopting the above technical scheme, a support frame is installed on the outside of the cantilevered eaves, the support frame extends outward, and the waterproof board is installed on the support frame, so as to increase the shielding area of ​​the cantilevered eaves and prevent rainwater from wetting the exterior wall. In addition, the end of the support frame extending outward is tilted upward, so that the height of the top aluminum plate on the outside of the cantilevered eaves is higher than that on the inside, so that rainwater on the aluminum plate flows to the inside of the cantilevered eaves to the drainage trough, reducing dripping on the outside of the exterior wall, which is beneficial to the protection of the exterior wall. Adjacent waterproof boards are sealed and connected, so that the joints of the waterproof boards are not prone to leakage, ensuring the dryness of the inner side of the protective board, so that the cantilevered eaves are not prone to water seepage. A profile is arranged on the outside of the support frame, and the profile is sealed and connected to the waterproof board. The profile plays a transitional role, making the cantilevered eaves structure more beautiful.

[0008] Optionally, a plurality of embedded parts for fixing the support frame are embedded in the cantilevered eaves.

[0009] By adopting the above technical solution and setting embedded parts, there is no need for on-site drilling, which saves installation time and labor costs and improves work efficiency; the embedded parts have greater structural strength and heavy-load capacity, and the support frame is fixed on the embedded parts, making the installation of the support parts more stable.

[0010] Optionally, the support frame includes a first bracket arranged at the top of the cantilevered eave and a second bracket arranged at the outside of the cantilevered eave, one end of the first bracket extends toward the outside of the cantilevered eave, the first bracket is inclined upward away from one end of the cantilevered eave, and the second bracket is inclined upward away from one end of the cantilevered eave; it also includes a third bracket arranged at the bottom of the cantilevered eave for fixing the waterproof board.

[0012] Optionally, a reinforcing rib is provided at a connection between the second bracket and the embedded part.

[0013] By adopting the above technical solution, since the second bracket extends outward and is easily deformed due to the gravity of the waterproof board, reinforcing ribs are provided at the connection between the support frame and the embedded parts to increase the structural strength of the second bracket, thereby increasing the bearing capacity of the second support frame, making it less likely to deform and helping to increase the service life of the second bracket.

[0014] Optionally, a sealing strip is provided in the joint seam of the waterproof board, and opposite sides of the sealing strip respectively abut against the edges of the waterproof board, and the joint seam of the waterproof board is filled with sealant above the sealing strip.

[0015] By adopting the above technical scheme, since there are gaps at the joints of the waterproof boards, which are prone to water leakage, a sealing strip is set in the connecting seam and filled with sealant to ensure the sealing of the joints of the waterproof boards, making the joints of the waterproof boards less likely to leak, ensuring the dryness of the inner side of the waterproof boards, and making it less likely for water to seep into the overhanging eaves.

[0017] By adopting the above technical solution, a U-shaped waterproof groove is set below the joint of the waterproof board. When water leakage occurs at the joint of the waterproof board, the water will drip into the U-shaped waterproof groove and flow out from one end of the U-shaped waterproof groove, so that the water will not fall on the cantilevered eaves, thereby preventing water seepage from occurring in the cantilevered eaves.

[0018] Optionally, sound-absorbing rock wool is provided on the inner side of the waterproof board at the top end of the overhanging eaves.

[0019] By adopting the above technical solution, a cavity is formed between the waterproof board and the cantilevered eaves. When rainwater drops on the waterproof board, it is easy to generate noise to disturb the residents. Sound-absorbing rock wool is arranged on the inner side of the waterproof board to absorb the noise and reduce the interference of noise to residents.

[0024] Optionally, a waterproof layer is provided on the inner wall of the drainage trough, and a filter cover plate is provided at the opening of the drainage trough.

The support frame 2 is fixedly connected with a profile 5 at one end away from the overhanging eaves 1. The cross-section of the profile 5 is a semicircular structure, and the arc-shaped side of the profile 5 faces outward. One side of the plane of the profile 5 is fixedly connected to the end of the support frame 2, and the profile 5 is sealed to the waterproof board 3. The profile 5 plays a transition role, making the structure of the overhanging eaves 1 more beautiful.

[0038] When installing the aluminum plate, first, a support frame 2 is installed on the outside of the cantilevered eaves 1. The support frame 2 extends outward, and the waterproof board 3 is fixed on the support frame 2, thereby increasing the shielding area of ​​the cantilevered eaves 1, making it difficult for rainwater to wet the exterior wall 16, and the end of the support frame 2 extending outward is tilted upward, so that the height of the top aluminum plate on the outside of the cantilevered eaves 1 is higher than the height on the inside, so that rainwater on the aluminum plate flows to the inside of the cantilevered eaves 1, reducing dripping on the outside of the exterior wall 16, which is beneficial to the protection of the exterior wall 16; adjacent waterproof boards 3 are sealed and connected, so that the joints of the waterproof boards 3 are not prone to leakage, ensuring the dryness of the inner side of the protective board 14, so that the cantilevered eaves 1 is not prone to water seepage.

[0039] A drainage ditch 6 is preset on the inner side of the cantilevered eaves 1, and a waterproof layer 61 is laid on the inner wall of the drainage ditch 6. The waterproof layer 61 is laid inside the drainage ditch 6 to prevent the drainage ditch 6 from leaking easily, thereby effectively protecting the floor; a filter cover plate 62 is covered at the opening of the drainage ditch 6 to block external falling objects and prevent the water outlet of the drainage ditch 6 from being blocked.

[0040] A protective plate 14 is fixedly connected to the inner side of the external cantilever eave 1, one side of the protective plate 14 is sealed and connected to the edge of the waterproof plate 3, and the other side of the protective plate 14 is connected to the opening of the drainage groove 6. The protective plate 14 is used to block rainwater, so that the external cantilever eave 1 is not easy to leak water, and at the same time, it plays a protective role on the inner side of the external cantilever eave 1.

[0041] When constructing the external cantilever beam, a plurality of embedded parts 4 for fixing the support frame 2 are embedded in specific positions in the external cantilever eaves 1, and the support frame 2 is welded on the embedded parts 4.

Since the second bracket 22 extends outward and is subject to the gravity of the waterproof board 3, it is easy to deform. By arranging the reinforcing rib 24 at the connection between the support frame 2 and the embedded part 4, the structural strength of the second bracket 22 is increased, thereby increasing the load-bearing capacity of the second support frame 2, and it is not easy to deform, which is conducive to increasing the service life of the second bracket 22.

[0043] A sound-absorbing rock wool 15 is arranged on the inner side of the waterproof board 3 located at the top of the cantilevered eaves 1. A cavity is formed between the waterproof board 3 and the cantilevered eaves 1. When rainwater drops on the waterproof board 3, it is easy to generate noise to disturb residents.

[0045] The waterproof board 3 is fixed to the support frame 2 by the connecting piece 11, which is convenient for assembly and disassembly; a shock-absorbing pad 13 is arranged between the connecting piece 11 and the support frame 2 to reduce the loosening of the connecting piece 11 caused by vibration, so that the connection of the connecting piece 11 is more stable.

[0046] The waterproof board 3 preferably adopts a 3.0 mm single-layer aluminum plate.

[0047] The embedded parts 4, the support frame 2 and the reinforcing ribs 24 are all hot-dip galvanized to make the embedded parts 4, the support frame 2 and the reinforcing ribs 24 corrosion-resistant, highly durable and prolong the service life.

[0048] Reference Figure 1 and Figure 3A sealing strip 9 is provided in the gap between the joints of two adjacent waterproof boards 3, and the opposite sides of the sealing strip 9 are respectively in contact with the edges of the adjacent waterproof boards 3. The gap is filled with sealant 10 above the sealing strip 9, so that the joints of the waterproof boards 3 are not prone to water leakage, the inner side of the waterproof boards 3 is kept dry, and the cantilevered eaves 1 are not prone to water seepage.

[0049] A U-shaped waterproof groove 7 is arranged below the joint of the waterproof board 3 at the top of the cantilevered eaves 1. The length direction of the U-shaped waterproof groove 7 is arranged along the cantilevered direction of the cantilevered eaves 1. The side plate 71 of the U-shaped waterproof groove 7 is located on the inner side of the edge of the waterproof board 3. The U-shaped waterproof groove 7 is fixedly connected to the support frame 2.

One end of the guide wire 83 away from the flat steel 82 is connected to the ground, so as to guide the lightning that hits the overhanging eaves 1 to the ground and ensure the personal safety of people in the building.

[0051] The implementation principle of the aluminum plate cantilever eaves structure of the embodiment of the present application is: when constructing the cantilever eaves 1, an embedded part 4 is pre-buried at a specific position of the cantilever eaves 1, the support frame 2 is welded to the embedded part 4, the support frame 2 extends outward, and the waterproof board 3 is fixed to the support frame 2 through the connecting piece 11, thereby increasing the shielding area of ​​the cantilever eaves 1 and making it difficult for rainwater to wet the outer wall 16; and the end of the support frame 2 extending outward is tilted upward, so that the height of the top aluminum plate located on the outer side of the cantilever eaves 1 is higher than the height on the inner side, so that rainwater on the aluminum plate flows to the inner side of the cantilever eaves 1, reducing dripping on the outer side of the outer wall 16, which is beneficial to the protection of the outer wall 16; the gap at the connection between adjacent waterproof boards 3 is sealed by sealing strips 9 and sealant 10, so that the joints of the waterproof boards 3 are not prone to leakage, ensuring the dryness of the inner side of the protective board 14, so that the cantilever eaves 1 is not prone to water seepage. When water leaks at the joint of the waterproof board 3, the dripping water will drip into the U-shaped waterproof groove 7, and the dripping water will flow out from one end of the U-shaped waterproof groove 7, so that the dripping water will not fall on the cantilevered eaves 1, thereby making it difficult for water to seep into the cantilevered eaves 1. A profile 5 is fixedly connected to the outside of the support frame 2, and the profile 5 is sealed and connected to the waterproof board 3. The profile 5 plays a transition role, making the cantilevered eaves 1 more beautiful in structure.
