Description

Technical Field

[0001] The present application relates to the field of building curtain walls, and in particular to a drainage curtain wall unit. In addition, the present application also relates to a curtain wall Background Art

[0002] Curtain wall is the outer wall of the building, which is non-load-bearing and is hung like a curtain, so it is also called "curtain wall". It is a lightweight wall with decorative effect commonly used in modern large and high-rise buildings. Curtain wall is usually composed of panels and supporting structure system, which can have a certain displacement ability relative to the load-bearing main body of the building or a certain deformation ability itself. It is a building external protective structure or decorative structure that does not bear the load-bearing function of the building. It has been rapidly developed due to its advantages of light weight, strong earthquake resistance, strong modern atmosphere and easy update and maintenance.

[0003] In order to simplify the design and installation of curtain walls, curtain walls are usually made up of multiple identical curtain wall units. Each curtain wall unit includes a supporting frame and a panel. The supporting frame is fixed on the load-bearing body, and the panel is fixed on the outside of the supporting frame. While forming a gorgeous architectural appearance of the curtain wall, it also forms an isolation between the internal and external spaces of the building. However, the curtain wall formed by splicing curtain wall units inevitably has gaps between adjacent curtain wall units, which easily causes external rainwater to enter the supporting frame through the gaps between the panels. Once the rainwater in the supporting frame is not drained smoothly, it is very easy to cause rainwater to leak into the room.

[0004] The supporting frames in existing curtain wall units are mostly equipped with water retaining strips on the upper part of the beams, which block rainwater on the outer part of the beams and use the water's own gravity to drain water through the gaps between the panels. However, once the drainage structure has a large wind pressure outside the panels, the wind will blow inward through the gaps between the panels, blocking the water above the beam profiles, and even flowing over the water retaining strips above the beams into the room.

It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0045] In this application, unless otherwise stated, the directions or positional relationships indicated by the directional words such as "inside, outside, up, and down" are based on the directions or positional relationships when the curtain wall of this application is installed on the load-bearing body of the building's exterior wall. Among them, the direction close to the building's load-bearing body is "inside". The description of the directions or positional relationships of the drainage curtain wall unit and its components of this application is consistent with the installation directions in actual use.

[0046] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] An embodiment of the drainage curtain wall unit of the present application is as follows Figures 1 to 6 As shown, it includes an upper crossbeam 1, a lower crossbeam 2, a column 3 and a panel 4. Usually, two columns 3 are provided, and the two columns 3 are respectively fixed at the two ends between the upper crossbeam 1 and the lower crossbeam 2, and together with the upper crossbeam 1 and the lower crossbeam 2, they form a support frame for fixing and carrying the panel 4. The panel 4 is installed and fixed on the outside of the support frame to form the appearance of the drainage curtain wall unit. Usually, sealing strips are provided between the panel 4 and the upper crossbeam 1, the lower crossbeam 2 and the column 3 to prevent wind and rain outside the curtain wall from entering the interior of the building.

[0048] The upper cross beam 1 is usually made of aluminum alloy profiles, and includes an upper beam frame 11, an inner support plate 12 and an intermediate support plate 13. The upper beam frame 11 is arranged at the lower part of the upper cross beam 1, and constitutes the main load-bearing structure of the upper cross beam 1. The inner support plate 12 and the intermediate support plate 13 are arranged at intervals on the top surface of the upper beam frame 11, and extend upward from the top wall of the upper beam frame 11. A drainage transverse cavity 14 is arranged above the top surface of the upper beam frame 11 and outside the intermediate support plate 13. The drainage transverse cavity 14 extends along the length direction of the upper cross beam 1, and is sealed around, forming a drainage channel extending to both ends of the upper cross beam 1.

[0049] An independent vertical drainage cavity 31 is provided inside the column 3, and the vertical drainage cavity 31 extends up and down along the length direction of the column 3 and opens at both ends of the column 3. The column 3 is mounted on the upper crossbeam 1 so that the vertical drainage cavity 31 is located directly below the horizontal drainage cavity 14. A water hole 15 connecting the horizontal drainage cavity 14 and the vertical drainage cavity 31 is provided on the upper beam frame 11. The water in the horizontal drainage cavity 14 can be drained into the vertical drainage cavity 31 through the water hole 15 and discharged through the opening at the lower end of the vertical drainage cavity 31.

[0050] At the positions of the two ends of the upper crossbeam 1 directly opposite to the columns 3, a shedding board 5 is arranged above the drainage transverse cavity 14. A rain shield extending to the top of the panel 4 is also arranged on the outer side of the drainage transverse cavity 14 on the upper crossbeam 1. The shedding board 5 fits with the middle support plate 13, the top surface of the drainage transverse cavity 14 and the rain shield from the inside to the outside, respectively, to form a multi-bend shape connected by the side plate, the inclined bottom plate and the flat bottom plate. The shedding board 5 can guide the rainwater that flows out through the opening of the drainage vertical cavity 31 of the upper drainage curtain wall unit, and cause it to be discharged to the outside of the panel 4. The edge of the flat bottom plate of the shedding board 5 is located on the inner side of the rain shield, that is, on the inner side of the outer side of the panel 4, to prevent the edge of the shedding board 5 from extending out of the outer side of the panel 4 and affecting the appearance of the curtain wall.

[0051] In some embodiments of the drainage curtain wall unit of the present application, Figure 3 As shown, a windshield 16 is provided on the upper part of the top surface of the upper beam frame 11. The windshield 16 extends obliquely upward from the outer part of the beam frame top plate 111 of the upper beam frame 11, and is integrally connected to the beam frame top plate 111 and the middle support plate 13. A drainage transverse cavity 14 is formed between the beam frame top plate 111, the windshield 16 and the middle support plate 13, which is sealed all around and extends along the length direction of the upper crossbeam 1 at both ends. The windshield 16 not only covers the top of the drainage transverse cavity 14, forming a sealing structure around the drainage transverse cavity 14, but also forms an outwardly inclined water guide surface on the top of the upper beam frame 11, which is conducive to increasing the rainwater discharge force, so that rainwater can be discharged under a larger wind pressure environment.

[0052] In a preferred embodiment of the drainage curtain wall unit of the present application, Figure 4As shown, the height of the inner support plate 12 on the top surface of the upper beam frame 11 is higher than the height of the intermediate support plate 13 on the top surface of the upper beam frame 11. On the top surface of the upper beam frame 11, the inner side of the intermediate support plate 13 is surrounded by the inner support plate 12, the intermediate support plate 13 and the beam frame top plate 111 to form a profile groove 17. The higher height of the inner support plate 12 can block part of the rainwater that passes over the intermediate support plate 13 in the profile groove, preventing the rainwater from further leaking to the inner side of the drainage curtain wall unit.

[0053] At the bottom of the middle support plate 13, an internal water hole 131 is set close to the beam frame top plate 111. The internal water hole 131 connects the profile groove 17 and the drainage transverse cavity 14. The water in the profile groove 17 can flow into the drainage transverse cavity 14 through the internal water hole 131, and be discharged into the drainage vertical cavity 31 through the water hole 15 at the bottom of the drainage transverse cavity 14.

[0054] In some embodiments of the drainage curtain wall unit of the present application, Figure 5 and Figure 6 As shown, a lower beam support groove 21 extending along the length direction of the lower beam 2 is provided on the bottom surface of the lower beam 2. The lower beam support groove 21 is recessed from the bottom surface of the lower beam 2 to form an upwardly recessed rectangular groove. The position of the lower beam support groove 21 on the lower beam 2 corresponds to the position of the middle support plate 13 on the upper beam 1. When multiple drainage curtain wall units are combined with each other in the up-down direction, the middle support plate 13 of the lower drainage curtain wall unit can be supported in the lower beam support groove 21 of the upper drainage curtain wall unit to ensure the position stability between the two.

When the column 3 and the lower cross beam 2 are connected to each other, the column support groove 32 is located at the end of the lower beam support groove 21 and is combined with the lower beam support groove 21 to form the same support groove that passes through the bottom surface of the supporting frame and accommodates the middle support plate 13.

[0056] In a preferred embodiment of the drainage curtain wall unit of the present application, Figure 4 As shown, column matching grooves 18 are provided below both ends of the upper cross beam 1. The column matching grooves 18 are formed by cutting off a section of other structures below the beam frame top plate 111 at the end of the upper beam frame 11. When the column 3 is installed on the upper cross beam 1, the upper end of the column 3 extends into the column matching groove 18 and is connected to the beam frame top plate 111, so that the end surface of the column 3 is tightly abutted against the beam frame top plate 111.

[0057] The water hole 15 is arranged on the beam frame top plate 111, just above the drainage vertical cavity 31. The upper part of the water hole 15 opens into the drainage horizontal cavity 14, and the lower part opens into the drainage vertical cavity 31, forming a sealed connection between the drainage horizontal cavity 14 and the drainage vertical cavity 31.

[0058] like Figure 6 As shown, column support plates 22 are provided at both ends of the lower cross beam 2, and the column support plates 22 are provided on the lower cross beam 2 inside the lower beam support groove 21. When the column 3 and the lower cross beam 2 are connected to each other, the lower end surface of the column 3 is installed on the column support plate 22, and while forming a reliable connection between the column 3 and the lower cross beam 2, the opening of the drainage cavity 31 on the lower end surface of the column 3 is kept unobstructed.

[0059] In some embodiments of the drainage curtain wall unit of the present application, Figure 1 and Figure 2 as well as Figure 7 and Figure 8 As shown, the drainage curtain wall unit of the present application further includes a mounting structure 6.

The mounting base plate 631 is provided with a wall mounting groove, and the mounting seat 63 can be securely fixed on the mounting surface of the external wall load-bearing body by passing the fastening bolts through the wall mounting groove.

[0061] In a preferred embodiment of the drainage curtain wall unit of the present application, Figure 7 and Figure 8 As shown, the fixing block 61 includes a column fixing plate 611, a connecting positioning plate 612 and a threaded fixing block 613.

The mounting seat reinforcing plate 633 is fixedly connected between the mounting base plate 631 and the mounting top plate 632, and is arranged perpendicular to the mounting base plate 631 and the mounting top plate 632, and is used to strengthen the connection strength between the mounting base plate 631 and the mounting top plate 632. A plurality of mounting seat reinforcing plates 633 can be provided, and a plurality of mounting seat reinforcing plates 633 are used to further ensure the connection strength between the mounting base plate 631 and the mounting top plate 632.

[0064] The column fixing plate 611 is fixed vertically on the column 3. Specifically, the column fixing plate 611 can be fixed directly on the side of the column 3 by screws, or a vertically extending installation groove can be opened on the inner side of the column 3, and the column fixing plate 611 is inserted into the interior of the column 3 through the installation groove, and then the column fixing plate 611 is fixed on the side of the column 3 by screws to fix the column fixing plate 611 on the column 3. The column fixing plate 611 is fixed on the column 3 so that the connection positioning plate 612 is parallel to the panel 4, the threaded fixing block 613 is fixed on the inner side of the connection positioning plate 612, and a fixing hole that runs through the upper and lower sides is provided on the threaded fixing block 613. The threaded fixing plate 621 is fixed to the threaded fixing block 613 by passing the fixing bolts through the fixing holes, so that a stable surface contact is formed between the threaded fixing plate 621 and the threaded fixing block 613. At the same time, the lower part of the connecting positioning plate 612 is inserted into the fixing block positioning groove 624, which further improves the connection stability between the fixing block 61 and the connecting block 62 and enhances the bearing strength of the connection structure therebetween.

[0065] The mounting top plate 632 and the mounting connecting plate 623 are fixedly connected by bolts, and the two form surface contact on a horizontal plane, thereby ensuring the connection stability between the connecting block 62 and the mounting seat 63 and the bearing strength of the connection structure.
