Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically a waterproof structure for roof eaves in building construction. Background Technology
[0002] In actual building construction, waterproofing and leak prevention are always important construction projects because they are closely related to the building's safety against leaks. Therefore, a good building design and roof eaves waterproofing structure are particularly important.
[0003] In the existing roof eaves waterproofing structure, during the process of drainage and water diversion, when rainwater flows to the edge of the eaves, some rainwater will flow back along the bottom of the eaves due to inertia, while some rainwater will flow directly down from the edge of the eaves, thus keeping it away from the roof wall. However, the rainwater flowing back along the bottom of the eaves due to inertia will flow close to the wall. The bottom of the eaves is not conducive to guiding the rainwater, making it difficult for the rainwater to fall accurately into the drainage structure, causing the rainwater to seep into the roof wall.
[0004] Therefore, those skilled in the art provide a waterproof structure for roof eaves in building construction to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to provide a waterproof structure for roof eaves in building construction, so as to solve the problem mentioned in the background art that the existing roof eaves structure is not conducive to guiding and draining rainwater, and rainwater is prone to backflow.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A waterproof structure for roof eaves in building construction includes: an eave, the edge of which is integrally provided with a bend, and a wedge-shaped groove is fixedly provided on the lower surface of the bend; a drainage channel is installed below the eave, and an inclined flow channel is installed inside the drainage channel; a first drainage pipe is provided at the inclined lower end of the inclined flow channel; a diversion channel is provided on one side of the inclined flow channel, and a second drainage pipe is provided at the inclined lower end of the diversion channel; and a notch is fixedly provided on the surface of the diversion channel.
[0008] As a further improvement of this utility model: the bending direction of the angle is opposite to the extension direction of the eaves, and the wedge-shaped grooves are equidistantly distributed along the surface of the angle.
[0009] As a further improvement of this utility model: a support frame is fixedly connected to the bottom of the eaves, and steel frames are fixedly connected to the left and right sides of the support frame.
[0010] As a further improvement of this utility model: the support frame is equidistantly distributed along the bottom of the eaves, and a crossbeam is fixed at the lower end of the support frame.
[0011] As a further improvement of this utility model: the inclined flow channel and the diversion channel are mirror-symmetrical about the center line and are arranged in parallel, and the inclined flow channel and the diversion channel have the same inclination angle.
[0012] As a further improvement of this utility model, the inclined flow channel and the diversion channel are interconnected through a notch.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. A bend is set at the edge of the eaves, with the bend curving inward. A wedge-shaped groove is set on the bottom surface of the bend. The wedge-shaped groove is used to divert the rainwater flowing at the edge of the eaves, so that the rainwater flows along the wedge into the drainage channel below the edge of the eaves. This diverts and drains the rainwater, preventing the wall from getting wet and seeping when the rainwater flows back from the edge of the eaves due to inertia.
[0015] 2. The drainage channel is equipped with an inclined flow channel and a diversion channel. Drainage pipe 1 and drainage pipe 2 are installed at the inclined lower end of the inclined flow channel and the diversion channel. Drainage pipe 1 and drainage pipe 2 are used to drain rainwater. When there is a lot of rain, the rainwater in the inclined flow channel will flow into the diversion channel through the horizontal point where it intersects with the diversion channel and the opening on the diversion channel, so as to divert and drain the rainwater, prevent rainwater backflow, and avoid water accumulation and seepage at the eaves.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-6 This utility model provides a waterproof structure for roof eaves in building construction, including: an eave 1, with an integrally fixed bend 11 on the edge of the eave 1, and a wedge-shaped groove 12 fixedly opened on the lower surface of the bend 11. The bending direction of the bend 11 is opposite to the extension direction of the eave 1, and the wedge-shaped grooves 12 are equidistantly distributed along the surface of the bend 11. A drainage channel 2 is installed below the eave 1, and an inclined flow channel 6 is fixedly installed inside the drainage channel 2. A first drainage pipe 8 is fixedly connected to the inclined lower end of the inclined flow channel 6. A diversion channel 7 is fixedly installed on one side of the inclined flow channel 6, and a second drainage pipe 9 is fixedly installed at the inclined lower end of the diversion channel 7. A notch 10 is fixedly opened on the surface of the diversion channel 7.
[0025] Specifically, the edge of the eaves 1 is integrally provided with a bend 11, and a wedge-shaped groove 12 is fixedly opened on the bottom surface of the bend 11. The wedge-shaped groove 12 is provided to guide rainwater in an orderly manner. A drainage channel 2 is independently installed below the eaves 1. The drainage channel 2 is fixed to the wall using wall expansion bolts. The edge of the eaves 1 is integrally connected to the bend 11, which bends the edge of the eaves 1 inward, thereby guiding the rainwater to the bottom of the eaves 1 and allowing the rainwater to flow into the drainage channel 2 below the eaves 1. By bending the bend 11 inward to guide the water, the drainage channel 2 is located below the eaves 1, avoiding the drainage channel 2 from protruding from the edge of the eaves 1 and causing irregularities in the edge of the eaves 1, which would reduce its aesthetics.
[0026] A support frame 3 is fixedly connected to the bottom of the eaves 1, and steel frames 4 are fixedly connected to the left and right sides of the support frame 3. The support frames 3 are evenly distributed along the bottom of the eaves 1, and a crossbeam 5 is fixed to the lower end of the support frame 3.
[0027] Specifically, the eaves 1 are supported and installed by using the support frame 3 and the steel frame 4 to prevent the eaves 1 from breaking and to improve the stability of the eaves 1. The stability is improved by using the crossbeam 5 for support.
[0028] The inclined flow channel 6 and the diversion channel 7 are mirror-symmetrical about the center line and are arranged in parallel. The inclined flow channel 6 and the diversion channel 7 have the same inclination angle. The inclined flow channel 6 and the diversion channel 7 are connected to each other through the notch 10.
[0029] Specifically, the inclined flow channel 6 and the diversion channel 7 are set up in a mirror image, with the center line of the inclined surface of the inclined flow channel 6 corresponding to the center line of the inclined side of the diversion channel 7. This makes the inclined flow channel 6 and the diversion channel 7 set up in parallel with the front and back staggered. When there is a lot of rainwater accumulating inside the inclined flow channel 6, it will flow into the diversion channel 7 through the opening 10. When the accumulation depth is deep, the rainwater will also flow into the diversion channel 7 from the center point of the intersection of the inclined sides of the inclined flow channel 6 and the diversion channel 7, diverting the rainwater to the left and right. The rainwater is then drained out through the first drain pipe 8 and the second drain pipe 9, respectively, to prevent rainwater from accumulating and flowing back, and to prevent water accumulation and seepage at the eaves 1 and the roof.
[0030] The working principle of this utility model is as follows:
[0031] When using this utility model, rainwater flows along the roof to the eaves 1. When the rainwater reaches the edge of the eaves 1, it flows inward along the bend 11 and along the wedge groove 12, allowing it to flow into the drainage trough 2 below the eaves 1. The rainwater then flows into the inclined flow trough 6. When there is less rain, the rainwater flows into the first drain pipe 8 along the inclined flow trough 6 and is discharged from the roof through the first drain pipe 8. When there is more rain, the rainwater flows into the diversion trough 7 through the opening 10. After accumulating to a greater depth, the rainwater also flows into the diversion trough 7 from the center point of the intersection of the inclined sides of the inclined flow trough 6 and the diversion trough 7. In this way, the diversion trough 7 and the inclined flow trough 6 divide the rainwater to the left and right, respectively, and drain it out through the first drain pipe 8 and the second drain pipe 9, preventing the rainwater from accumulating and flowing back.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
