The anti-leakage roof cornice edge sealing structure comprises a fixed beam, the fixed beam is fixed to the outer side of the top of an outer wall, a top plate is obliquely and upwards installed at the upper end of the fixed beam from outside to inside, waterproof cloth is installed on the lower side of the top plate in an attached mode, and the outer end of the waterproof cloth extends downwards to wrap the outer side face of the fixed beam. Rainwater is prevented from moving to the gap along the cross beam; the inner wall of the inner side of the drainage channel is connected with the lower side of the top plate through a drainage plate, rainwater moving on the bottom face of the top plate is guided downwards, and direct washing of the rainwater to the outer wall is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to an anti-leakage roof eaves edge sealing structure. Background Art

[0002] Metal roofs rarely have gaps because they use complete metal plates on their surface. They are often used as roofs and are suitable for laying a wide range of large-surface machines. The intersection of the roof surface and the exterior wall is called the eaves. The waterproof performance of the eaves structure plays a very important role in ensuring the waterproof performance of the exterior wall. General board houses will install a roof drainage system at the eaves, but because the top surface of the exterior wall may be uneven, and the metal roof will use large flat metal plates to connect the roof panels to the exterior wall, resulting in gaps in the connection between the top surface of the exterior wall and the flat bottom surface of the metal roof. At this time, some rainwater will move inward along the horizontal surface of the bottom of the roof surface, causing rainwater to flow back into the house through the gaps at the connection and penetrate into the exterior wall, causing rainwater leakage on the exterior wall and roof surface. Utility Model Content

[0003] The utility model aims to provide an anti-leakage roof eaves edge sealing structure to solve the problem of rainwater flowing back and penetrating into the house through the gaps at the connection.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A leak-proof roof eaves edge sealing structure, which includes a fixed beam, which is fixed to the top outside of the outer wall, and a top plate is installed on the upper end of the fixed beam in an upward tilt from the outside to the inside, and a waterproof cloth is fitted on the lower side of the top plate, and the outer end of the waterproof cloth extends downward to wrap the outer side surface of the fixed beam, and a drainage channel is provided on the outer side of the fixed beam aligned with the lower end of the top plate, and the inner wall of the drainage channel is connected to the lower side of the top plate through a drainage plate.

[0006] A further technical solution is that a crossbeam is provided on the top of the fixed beam extending toward the outer wall, a first connecting hole is provided on the crossbeam running through the top and the bottom, and the first connecting hole is fixedly connected to the top of the outer wall by an expansion bolt.

[0007] A further technical solution is that a support beam is vertically arranged on one side of the cross beam away from the fixed beam, and the top of the support beam is fixedly connected to the lower side of the top plate.

[0008] A further technical solution is that the edge of the waterproof cloth is fixed to the lower side of the top plate through a molding, and the edge of the waterproof cloth is placed between the molding and the top plate; the side of the molding fits the lower side of the top plate; the side of the molding is perpendicular to the top plate and is provided with a second connecting hole, and the second connecting hole is fixed to the lower side of the top plate through a second self-tapping screw.

[0009] A further technical solution is that a third connecting hole is provided through one side of the drainage channel close to the drainage plate, and the third connecting hole is fixedly connected to the third connecting hole by a third self-tapping screw.

[0010] A further technical solution is that the upper end of the guide plate is bent and fitted under the top plate, and the bent portion of the guide plate is fixedly connected to the top plate by a fourth self-tapping screw.

[0011] A further technical solution is that the drainage channel is arranged to be inclined downward from one end to the other end, and a drainage pipe is vertically arranged below the opening of the lower end of the drainage channel.

[0012] A further technical solution is that a connecting column is provided on the outer side of the outer wall corresponding to the drain pipe in a transversely protruding manner, and the connecting column is sleeved on the outer wall of the drain pipe through a ring at the top.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) Wrap the connection between the top plate and the exterior wall with waterproof cloth to prevent rainwater from moving laterally along the beams at the connection and flowing back into the inner side of the exterior wall.

[0015] (2) Rainwater moving laterally from the bottom of the roof plate is guided downward through drainage channels and combined with drainage plates to keep rainwater away from the connection between the roof plate and the exterior wall, thereby reducing erosion and direct corrosion of the exterior wall by rainwater.

[0016] (3) By fixing the beams, the waterproof cloth is extended outwards. In the event of leakage in the top plate, the water flow is directed downwards and over the connection between the top plate and the outer wall, further preventing rainwater from flowing back into the inner side of the outer wall.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] Example 1:

[0022] A leak-proof roof eaves sealing structure, which includes a fixed beam 5, which is fixed to the outside of the top of the outer wall 2. The upper end of the fixed beam 5 is installed with a top plate 1 inclined upward from the outside to the inside. A waterproof cloth 6 is installed on the lower side of the top plate 1. The outer end of the waterproof cloth 6 extends downward to wrap the outer side of the fixed beam 5. A drainage channel 7 is provided on the outer side of the fixed beam 5, aligned with the lower end of the top plate 1. The inner wall of the inner side of the drainage channel 7 is connected to the lower side of the top plate 1 through a guide plate 8. When the rainfall exceeds the drainage limit of the drainage channel 7, the drainage channel 7 will overflow from the side. The guide plate 8 is used to block the rainwater overflowing from the side of the drainage channel 7 and guide the rainwater to a place away from the connection for drainage, so that the rainwater is away from the top plate 1 and the outer wall 2, and the direct erosion of the outer wall 2 by rainwater is reduced.

[0023] Example 2:

[0024] A crossbeam 3 is provided at the top of the fixed beam 5 extending toward the outer wall. A first connecting hole 11 is provided on the crossbeam 3 running through the upper and lower parts. The first connecting hole 11 is fixedly connected to the top of the outer wall 2 through an expansion bolt 10; the expansion bolt 10 is used to fix the central fulcrum of the crossbeam 3. The expansion bolt 10 is used to fix the crossbeam 3 axially along the top surface of the outer wall 1 above the outer wall 1 to prevent the crossbeam 3 and the top plate 1 from offsetting relative to the outer wall 2, thereby ensuring the stability of the house.

[0025] Example 3:

[0026] A support beam 4 is vertically arranged upward on one side of the cross beam 3 away from the fixed beam 5, and the top of the support beam 4 is fixedly connected to the lower side of the top plate 1; the support beam 4 is used to set the top plate 1 to be an inclined surface with one end closer to the inside of the house higher than the other end, so that rainwater can be guided to the drainage ditch 7 below.

[0027] Example 4:

[0028] The edge of the waterproof cloth 6 is fixed to the lower side of the top plate 1 by the pressure strip 14, and the edge of the waterproof cloth 6 is placed between the pressure strip 14 and the top plate 1; the side of the pressure strip 14 is in contact with the lower side of the top plate 1; the side of the pressure strip 14 is perpendicular to the top plate 1 and is provided with a second connecting hole 12, and the second connecting hole 12 is fixed to the lower side of the top plate 1 by a second self-tapping screw 15; the pressure strip 20 is used to fix the waterproof cloth 6 made of flexible material, and is combined with the waterproof cloth 6 to extend downward to wrap around the fixed beam 5. The other end of the waterproof cloth 6 is fixed to the outside of the outer wall 2. The waterproof cloth 6 is straightened and in contact with the top plate 1 to prevent the waterproof cloth 6 from being dented due to the weight of the infiltrated rainwater, thereby causing water accumulation, and the evaporated water vapor further corrodes the top plate 1; because the waterproof cloth 6 is thin, the side of the pressure strip 20 close to the top plate 1 needs to be tightly fitted to the top plate 1. Through the second connecting hole 12, the second self-tapping screw 15 is fixed perpendicularly to the top plate 1 to the lower side of the bottom plate 1, so that the side of the pressure strip 20 is always in contact with the top plate 1.

[0029] Example 5:

[0030] A third connecting hole 13 is provided at one end of the drainage channel 7 near the drainage plate 8, the drainage plate 8 is aligned with the third connecting hole 13, and the drainage plate 8 is fixedly connected to the drainage channel 7 by a third self-tapping screw 16 passing through the third connecting hole 13; a third threaded hole 17 is provided on the drainage plate 8 to match the third self-tapping screw 16, and the drainage plate 8 is fixedly connected to the drainage channel 7 by a third self-tapping screw 16 passing through the third connecting hole 13 and screwing the third threaded hole 17.

[0031] Example 6:

[0032] The upper end of the drainage plate 8 is bent and fits under the top plate 1, and the bent part of the drainage plate 8 is fixedly connected to the top plate 1 by a fourth self-tapping screw 17; the drainage plate 8 is used to fix the relative position of the drainage channel 7 and the top plate 1, so that the obliquely placed top plate 1 guides rainwater to the drainage channel 7 for drainage; the top end of the drainage plate 8 is fitted with the top plate 1 and bent inward, so that the drainage plate 8 is always vertically installed on the lower part of the top plate 1, so that the drainage plate 8 guides the rainwater flowing out of the bottom end of the top plate 1 to flow vertically downward, reducing the rust of the fourth self-tapping screw 17 on the top, and at the same time reducing the erosion of the exterior wall by rainwater; a fourth connecting hole is provided through the bent part, and a fourth threaded hole is provided on the bottom surface of the lower end of the top plate 1 aligned with the fourth connecting hole. The drainage plate 8 is screwed to the fourth threaded hole through the fourth connecting hole by a fourth self-tapping screw 17 and fixed to the bottom of the top plate 1.

[0033] Example 7:

[0034] The drainage channel 7 is arranged to be inclined downward from one end to the other end, and a drainage pipe 18 is vertically arranged below the opening of the lower end of the drainage channel 7; the drainage pipe 18 is used to collect rainwater and guide the rainwater downward. The inclined arrangement of the drainage channel 7 can prevent excessive water accumulation inside and most of the rainwater that overflows will follow the direction of the drainage channel 7 and move to the drainage pipe 18.

[0035] Example 8:

[0036] A connecting column 19 is provided on the outer side of the outer wall 2 corresponding to the drain pipe 18 in a transversely protruding manner. The connecting column 19 is connected to the outer wall of the drain pipe 18 through the ring 20 at the top; the ring 24 and the connecting column 23 are used to fix the relative position of the drain pipe 18 to the drainage channel 7, keeping the drain pipe 18 placed vertically.
