Technical Field
[0001] The utility model relates to the technical field of curtain walls, and specifically, to a waterproof structure at the junction of the ground and the curtain wall. Background Art
[0002] A curtain wall is a structural system on the exterior facade of a building. It does not bear the load and action of the main building structure, but transfers its own load and all external forces received to the main structure. Modern curtain walls are usually composed of metal frames and various filling materials, such as glass, stone, ceramic panels, aluminum composite panels, metal single panels, etc. The curtain wall not only provides an aesthetic appearance for the building, but also has functions such as heat preservation, heat insulation, sound insulation, and fire prevention, and can meet the requirements of lighting and ventilation.
[0003] In actual use of the curtain wall, since the junction between the curtain wall and the ground is prone to water accumulation when it rains, if the sealing is not tight or the drainage is not timely, rainwater will enter the room, and long-term water accumulation at the joint will also cause certain corrosion damage to the joint, affecting the beauty and service life of the curtain wall.
[0004] Therefore, there is an urgent need to provide a waterproof structure at the junction of the ground and the curtain wall to solve the above problems. Summary of the Utility Model
[0005] In order to solve the problems that the joint between the existing curtain wall and the ground is prone to water accumulation, causing corrosion damage to the joint and possibly allowing rainwater to enter the room, the utility model provides the following technical solution: A waterproof structure at the junction of the ground and the curtain wall, including a curtain wall.
[0006] Wherein, a rain shield is arranged at the bottom end of the curtain wall. A plurality of chambers are opened in the rain shield to receive possible rain leakage at the joint between the rain shield and the curtain wall. A diversion groove is arranged at the bottom end of the rain shield to receive the rainwater flowing down from the rain shield. Drainage openings corresponding to and communicating with the chambers are opened on the rain shield to drain the accumulated water in the chambers. By setting the inclined surface of the rain shield to introduce rainwater into the diversion groove, and then the concave drainage plate in the diversion groove gathers the rainwater in the diversion groove to the concave part and then discharges it through the drainage openings. Moreover, a plurality of chambers that fit the curtain wall are opened in the rain shield as a plurality of barriers to receive rain leakage at the joint. At the same time, drainage openings are also opened in the chambers to drain the rainwater that even flows into the chambers, thereby effectively solving the problems that the joint between the existing curtain wall and the ground is prone to water accumulation, causing corrosion damage to the joint and possibly allowing rainwater to enter the room.
[0007] As a further improvement of the technical solution, the rain shield seat has a right triangle structure, and the right-angled sides of the rain shield seat are respectively attached to the curtain wall and the ground; the right triangle structure of the rain shield seat can guide rainwater to flow downward along the inclined plane, avoiding rainwater from directly seeping into the connection between the curtain wall and the ground.
[0008] As a further improvement of the technical solution, the diversion groove has a U-shaped structure, and one side is attached to the rain shield seat, both are inclined, the other side is vertically arranged, and a drainage plate is fixedly connected in the diversion groove.
[0009] As a further improvement of the technical solution, the drainage plate has a concave structure, with both ends high and the middle low, and a drainage port is opened at the lowest part of the drainage plate on the side perpendicular to the diversion groove, for conveniently gathering rainwater in the concave part and then discharging it; with the design of the drainage plate in the diversion groove, rainwater is gathered at the lowest point of the concave structure, ensuring that rainwater can be efficiently discharged from the drainage port, avoiding water accumulation and reducing the corrosion risk at the connection.
[0010] As a further improvement of the technical solution, one side of several of the chambers close to the curtain wall is in an open state, for the lower chambers to receive the rainwater that the upper chambers fail to receive, and several chambers form multiple defenses and jointly form a rainwater leakage prevention barrier.
[0011] As a further improvement of the technical solution, several of the drainage ports are distributed obliquely, for preventing the rainwater discharged from the upper drainage ports from entering the lower chambers through the lower drainage ports.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] 1. For the waterproof structure at the junction of the ground and the curtain wall, through the fitting of the rain shield seat with the curtain wall and the ground, and the right triangle structure of the rain shield seat, it can guide rainwater to flow downward along the inclined plane, avoiding rainwater from directly seeping into the connection between the curtain wall and the ground, thereby reducing the possibility of rainwater penetrating into the room.
[0014] 2. For the waterproof structure at the junction of the ground and the curtain wall, through the multiple chambers arranged in the rain shield seat, when there is a slight leakage at the connection between the curtain wall and the rain shield seat, these chambers can serve as multiple defenses to intercept rainwater layer by layer, forming a leakage prevention barrier to prevent rainwater from further eroding the connection part between the curtain wall and the ground.
[0015] 3. For the waterproof structure at the junction of the ground and the curtain wall, through the design of the drainage plate in the diversion groove, rainwater is gathered at the lowest point of the concave structure, ensuring that rainwater can be efficiently discharged from the drainage port, avoiding water accumulation and reducing the corrosion risk at the connection.
[0016] 4. For the waterproof structure at the junction of the ground and the curtain wall, through the connection between the drain outlet at the bottom of the chamber and the diversion groove, even if rainwater accumulates in the chamber, it can be quickly discharged, avoiding the retention of rainwater in the chamber and further reducing the damage of rainwater to the connection between the curtain wall and the ground.
[0017] 5. For the waterproof structure at the junction of the ground and the curtain wall, through the oblique design of the drain outlet and the setting beyond the rain shield, it effectively prevents the direct intrusion of oblique rainwater, while ensuring the smooth discharge of rainwater in the chamber, improving the reliability of the overall waterproof structure.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0028] Please refer to Figures 1 - 7As shown in the figure, the purpose of this embodiment is to provide a waterproof structure at the junction of the ground and the curtain wall, including a curtain wall 1. A rain shield 2 is provided at the bottom end of the curtain wall 1. A number of chambers 3 are opened in the rain shield 2 to receive possible rain leakage at the connection between the rain shield 2 and the curtain wall 1. A diversion trough 6 is provided at the bottom end of the rain shield 2 to receive the rainwater flowing down from the rain shield 2. Drainage openings 4 corresponding to and communicating with the chambers 3 one by one are opened on the rain shield 2 to drain the accumulated water in the chambers 3.
[0029] Furthermore, the rain shield 2 is in a right triangle structure, and the right-angled sides of the rain shield 2 are respectively in contact with the curtain wall 1 and the ground. When the rain hits the curtain wall 1, it flows along the curtain wall 1 to the rain shield 2. Due to its right triangle structure and the right-angled sides being respectively in contact with the ground and the curtain wall 1, the rainwater will flow along its inclined surface into the lowest diversion trough 6.
[0030] Specifically, the diversion trough 6 is in a U-shaped structure, and one side is in contact with the rain shield 2, both are inclined, and the other side is vertically arranged, and a drainage plate 5 is fixedly connected in the diversion trough 6.
[0031] Further, the drainage plate 5 is in a concave structure, with both ends high and the middle low. A drainage opening 4 is opened at the lowest part of the drainage plate 5 on the vertical side of the diversion trough 6 to facilitate the accumulation of rainwater in the concave part and then drain it. The drainage plate 5 is arranged in the U-shaped groove of the diversion trough 6 and is in a concave structure. Therefore, the rainwater will accumulate in the concave part and then be discharged through the drainage opening 4 provided on one side of the diversion trough 6 and at the concave part.
[0032] In addition, one side of a number of chambers 3 close to the curtain wall 1 is in an open state to allow the lower chambers 3 to receive the rainwater that the upper chambers 3 fail to receive. A number of chambers 3 form multiple lines of defense and jointly form a rain leakage prevention barrier.
[0033] In addition, a number of drainage openings 4 are distributed obliquely to prevent the rainwater discharged from the upper drainage openings 4 from entering the lower chambers 3 through the lower drainage openings 4. It should be added here that a number of drainage openings 4 extend beyond the rain shield 2 and are inclined downward at a certain angle to prevent the obliquely falling rainwater from directly entering the chambers 3 through the drainage openings 4 and to facilitate the drainage of the rainwater in the chambers 3.
[0034] The specific working principle is as follows:
[0035] When it rains, when the rain hits the curtain wall 1, it flows along the curtain wall 1 to the rain shield 2. Due to its right triangle structure and the right-angled sides being respectively in contact with the ground and the curtain wall 1, the rainwater will flow along its inclined surface into the lowest diversion trough 6. And because the drainage plate 5 is arranged in the U-shaped groove of the diversion trough 6 and is in a concave structure, the rainwater will accumulate in the concave part and then be discharged through the drainage opening 4 provided on one side of the diversion trough 6 and at the concave part.
[0036] If the connection between the top of the rain shield seat 2 and the curtain wall 1 is not sealed for a long time, or other reasons cause a certain amount of small rainwater to flow into the gap through the top, then the multiple chambers 3 will play a multiple defense line, blocking the rainwater layer by layer, and together forming a barrier to prevent rainwater from flowing into the lowest end of the curtain wall 1 and the ground, and prevent it from flowing into the room. If rainwater enters each chamber 3, it will be discharged to the guide groove 6 through the drain port 4 opened on the inclined surface of the rain shield seat 2. It is worth mentioning that the multiple drain ports 4 are arranged beyond the rain shield seat 2 and are inclined downward at a certain angle, so as to prevent oblique rainwater from directly entering the chamber 3 through the drain port 4 and facilitate the discharge of rainwater in the chamber 3.
[0037] Finally, the rainwater is introduced into the guide groove 6 through the inclined surface of the rain shield seat 2, and then the concave drainage plate 5 in the guide groove 6 collects the rainwater in the guide groove 6 into the concave part and then discharges it through the drain port 4. In addition, a plurality of chambers 3 that fit the curtain wall 1 are provided in the rain shield seat 2 as a plurality of barriers to receive rain leakage at the connection. At the same time, the chamber 3 is also provided with a drain port 4 to discharge the rainwater even if it flows into the chamber 3, thereby effectively solving the problem that the connection between the existing curtain wall 1 and the ground is prone to water accumulation, causing corrosion damage to the connection and possibly causing rainwater to enter the room.
