Description

Technical Field

[0001] The invention belongs to the technical field of curtain walls, and in particular relates to an adaptive curtain wall system for special-shaped buildings. Background Art

[0002] Curtain walls are commonly used as exterior wall enclosure structures in modern large and high-rise buildings. They are usually composed of panels and supporting structural systems, and can have a certain displacement capacity relative to the main structure or a certain deformation capacity of their own. According to different materials, they can be divided into glass curtain walls, stone curtain walls, etc., and can also be divided into frame curtain walls and unit curtain walls according to different components.

[0003] In some modern large-scale and high-rise special-shaped buildings, the double-sided curved structure can improve wind resistance, but it indirectly increases the difficulty of curtain wall system installation. Especially for the curved exterior wall, the cross-sectional area decreases gradually with the increase of height. At this time, the total length of the unit block of each floor is different, and it is often necessary to use a separate mold for punching, which is a heavy mold opening work.

[0004] In the current modular construction process of curtain walls, the positions of the installation columns are changed by anchors to achieve flexible swings on the vertical plane. However, as the curvature of the outer arc surface of the special-shaped building changes, the total length of the unit blocks on each floor is different. In particular, the folding amount between two vertical unit blocks is difficult to adjust. It is inconvenient for the curtain wall as a whole to achieve adaptive special-shaped outer arc surfaces of buildings with fewer molds. Summary of the invention

[0005] The purpose of the present invention is to provide an adaptive curtain wall system for special-shaped buildings, which can be partially folded in the horizontal and vertical directions as the curvature of the outer curved surface of the special-shaped building changes, so as to achieve adaptive outer curved surface of the special-shaped building with fewer molds, while taking into account the curvature change of the mortise and tenon joints and the ventilation path.

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0022] During the construction process, some special-shaped buildings have a top-down outline that is approximately elliptical, axially symmetrical along the geometric center, and their edges are serrated broken line structures with a certain curvature. When building the external curtain wall, the curtain wall is modularized, and the angle of each module is adjusted during processing to facilitate punching out the excess parts, which reduces the number of profile molds and the use of molds.

[0023] like Figure 1-Figure 13 As shown, an adaptive curtain wall system for special-shaped buildings comprises: Multiple unit panels 1 surrounding the exterior of the building, reference Figure 1-Figure 6, used for the outer curved surface of special-shaped buildings, there can be a certain amount of wave-shaped folding between the upper and lower layers of unit panels 1, and there can be a certain amount of wave-shaped folding between horizontally adjacent unit panels 1.

[0024] Among them, the unit panel 1 of this embodiment is preferably 8HS+1.52PVB+8HS (Low-E) double silver+12Ar (black warm edge)+10FTmm ultra-white laminated glaze insulating glass. When the glass warping value is greater than 1 / 60 of the short side of the glass, hyperbolic glass must be used. The thickness of the curved glass laminate is 3.04mm, which has obvious wind resistance in high-rise and super-high-rise buildings and is not easy to twist or crack.

[0025] Connecting seats, several connecting seats are respectively arranged in the middle of two horizontal unit plates 1 corresponding to the building wall surface, the connecting seats include plate-shaped steel adapters 2, the backs of the steel adapters 2 are fixed to the building wall surface, pin holes 3 are opened on the steel adapters 2, connecting bolts 4 are inserted inside the pin holes 3, the steel adapters 2 are hinged with hangers 5 through the connecting bolts 4, two adjacent hangers 5 are in the shape of alloy plates with round holes, wherein the steel adapter 2 is a right-angled structure, and the aluminum alloy hanger 201 is fixed to the groove-type embedded part by T-bolts to be fixedly connected to the steel adapter 2.

[0026] The alloy window sills are arranged between the back of the unit plate 1 and the connecting seat. The alloy window sills include a positioning protrusion 6 and a positioning groove 7 which are connected to each other by mortise and tenon joints.

[0027] Aluminum alloy frame, the aluminum alloy frame is arranged on the back of the unit plate 1, and partly penetrates the alloy window sill plate. The aluminum alloy frame is suspended on the outer surface of the building through the connecting seat and the alloy window sill plate.

[0028] Ventilator 8 is horizontally mounted on the alloy window sill, with side strips 802 fixed on both sides of the ventilator 8. The ventilator 8 has a concave socket 801 clamped by two side strips 802, and one side of the socket 801 is fixedly connected to the upper surface of the aluminum alloy lower beam 13. The ventilation path of the ventilator 8 is curved, which can prevent rainwater from entering while taking into account the ventilation needs.

[0029] During construction, the steel adapter 2 is fixed in advance by the groove-type embedded parts, the connecting bolt 4 is loosened, and the connecting bolt 4 and the hanger 5 are moved along the pin hole 3. The curtain wall node is convex outward away from the wall, and the curtain wall node is concave inward close to the wall, so as to adjust the wave-shaped folding amount of the unit panel 1, alloy window sill, aluminum alloy frame and ventilator 8. As the curvature of the outer arc surface of the special-shaped building changes, they can be partially folded in the horizontal and vertical directions, so that the total length of each layer of the unit panel 1 is different. During the processing, the excess part is punched out to realize the adaptive outer arc surface of the special-shaped building with fewer molds, and then the positioning protrusion 6 and the positioning groove 7 are inserted tightly, and the connecting bolt 4 is tightened to firmly support the aluminum alloy frame, the unit panel 1 and the ventilator 8, taking into account the curvature change of the mortise and tenon joints and the ventilation path.

[0030] In particular, the curtain wall nodes below the 19th floor of the special-shaped building gather rainwater obviously on rainy days, and the rainwater covers a wide area. The installation of ventilators 8 can prevent rainwater on one side and take ventilation into account on the other side, which is something that traditional curtain wall systems cannot do without damaging the wall on a large scale.

The side of the male column 9 close to the female column 10 is fixedly connected to the root of the positioning protrusion 6, and the positioning groove 7 is opened on the side of the female column 10 close to the male column 9. The male column 9 and the female column 10 are respectively fixedly connected to the edges of two adjacent hangers 5 close to the unit plate 1 by screws, and the round holes of the hangers 5 are used to insert the screws. In this embodiment, the number of each positioning protrusion 6 and the positioning groove 7 is two, and arc plates can be integrally arranged on both sides of the positioning groove 7, so that the positioning protrusion 6 can be hooked with the arc plate for limiting after insertion, forming a more stable mortise and tenon connection structure with a simple structure and convenient installation.

The adjacent aluminum alloy columns 11 are plugged in and tightened with screws, and then the alloy window sill, the aluminum alloy upper beam 12 and the aluminum alloy lower beam 13 are tightened by screws to complete the inner layer structure skeleton assembly for carrying each unit plate 1.

[0033] Refer to the attached Figure 8 , Fig. 9 and Fig.13 Two aluminum alloy buckle covers 14 connected to the male column 9 and the female column 10 are respectively arranged on both sides of the unit panel 1.

The two aluminum alloy buckle covers 14 stick to the outer surface of the unit panel 1 on one side and penetrate into the gap with the adjacent unit panel 1 on the other side. The unit panels 1 are glued layer by layer on the outside of the inner structural skeleton, and then the aluminum alloy buckle covers 14 are inserted into the gap between the adjacent unit panels 1 for sealing, which significantly improves the rainproof performance of the curtain wall system. The unit panels 1 are tightly connected to disperse the load brought by the high-rise airflow. Finally, the gap between the aluminum alloy buckle cover 14 and the unit panel 1 is filled with silicone sealant and a foam rod to further improve the sealing performance, and it is sun-proof and anti-aging.

One end of the aluminum alloy edge guard 17 extends outward to the distance between two adjacent unit panels 1. The end face of the aluminum alloy edge guard 17 is a wedge-shaped opening and a thermal insulation strip 18 is inserted at the opening. The outer edge of the thermal insulation strip 18 is connected to the inner edge of the aluminum alloy buckle cover 14. Screws are inserted into the aluminum alloy edge guard 17 to tighten the aluminum alloy upper beam 12 and the aluminum alloy lower beam 13 respectively to further strengthen the inner structural skeleton, and the thermal insulation strip 18 is used to isolate the external heat to improve the thermal insulation performance of the curtain wall system. At the same time, the thermal insulation strip 18 is made of an elastic material mixed with 25% and 75% nylon 66, and has good buffering performance.

[0036] Refer to the attached Figure 6 , Fig.11 and Fig.14An arrow-shaped EPDM rubber strip 19 is fixed to the end of the positioning protrusion 6, and the EPDM rubber strip 19 is interference fit with the positioning groove 7.
