Description

Technical Field

[0001] This invention relates to architectural glass curtain walls, belonging to the field of architectural curtain wall technology, and in particular to a freely variable angle installation system and method for inclined curtain wall arc corner beams. The system allows for infinitely variable angle installation of the inclined curtain wall beams at the arc corner of a straight curtain wall. Background Technology

[0002] Currently, the use of standard aluminum profile beams for the curved corner beams when transitioning from straight to tilted curtain walls presents a challenge in glass installation due to the difficulty in achieving the required torsional angle.

[0003] CN201510974890.0 discloses an arc-shaped unitized curtain wall system adaptable to arbitrary curved surfaces and its installation method. It includes several curtain wall units, each unit comprising male and female columns on both sides, and a top horizontal beam, a bottom horizontal beam, and a middle horizontal beam. A first concave curved glass panel is provided between the middle horizontal beam and the top horizontal beam, and a second concave curved glass panel is provided between the middle horizontal beam and the bottom horizontal beam. Each of the top, bottom, and middle horizontal beams has a vertical groove near the end of the first curved glass panel, in which a sub-frame connector is fastened. The top, bottom, and middle horizontal beams are respectively connected to the top sub-frame, bottom sub-frame, and middle sub-frame. The concave curvature of the fixing portion of the top, bottom, and middle sub-frames corresponds to the concave curvature of the first curved glass panel. A first support piece is provided at the bottom of the first curved glass panel, and a second support piece is provided at the bottom of the second curved glass panel. During installation, the curved unitized curtain wall effect can be achieved simply by bending the sub-frame. The advantages are: the curved unitized curtain wall system can adapt to any curved surface. By using only the bent glass sub-frame to fit the curved glass panels and create the curved architectural effect, it reduces the number of profiles that need bending, lowers profile bending costs, effectively improves the curvature accuracy of the beams, and ensures a high degree of fit between the interior beams and the glass. The installation process of the curved unitized curtain wall system, which can adapt to any curved surface, is convenient and cost-effective, improving profile processing efficiency, ensuring controllable project production schedule and quality, and significantly enhancing socio-economic benefits. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a freely variable angle installation system for the arc corner beam of the inclined curtain wall, so as to realize the installation of the arc corner beam of the inclined curtain wall with the glass connection trajectory as a gradual angle, and to realize the reliable installation of the curtain wall glass after twisting at different angles.

[0005] The objective of this invention is achieved through the following solution: a freely variable angle installation system for the curved corner beams of an inclined curtain wall, relating to the installation system for connecting the curved glass and the curved horizontal frame at the corner when the glass curtain wall transitions from an inclined curtain wall to a straight curtain wall. Specifically, it relates to the connection structure between the curtain wall glass and the horizontal frame system, used for installing and fixing the curtain wall glass, including a horizontally curved steel tube horizontal frame, a U-shaped steel pad frame, a horizontal frame steel plate adapter, a horizontal frame steel plate U-shaped component, and a curved horizontal frame, with the horizontally curved steel tube horizontal frame as the connecting element. On one side of the horizontally curved steel tube frame, the curtain wall glass is fixed to the U-shaped steel pad frame with adjustable angle by glass pressing U-grooves and fiberglass pressure plates through connectors. The U-shaped steel pad frame is fixedly connected to the curved horizontal frame through connectors, realizing a curtain wall with a concealed frame in the horizontal direction. On the other side of the horizontally curved steel tube frame, U-shaped steel plates of various angles are welded to the horizontally curved steel tube frame. The U-shaped steel plates are fixed to the curved horizontal frame through connectors, achieving a transition from a sloping curtain wall to a straight curtain wall.

[0006] Furthermore, the curtain wall glass is laminated insulated glass, with glass pressing U-grooves and fiberglass pressure plates set inside the sandwich layer, and fixed to a U-shaped steel pad frame with freely adjustable angle by connectors, thus realizing a curtain wall with a concealed frame in the horizontal direction.

[0007] The width of the upper and lower sides of the U-shaped steel pad frame varies with the inclination of the curtain wall, gradually changing from wider at the top and narrower at the bottom to equal width at both sides, and then back to narrower at the top and wider at the bottom. The welding points with the cylindrical surface of the horizontal curved steel tube frame also change, allowing for free angle adjustment.

[0008] This invention overcomes the shortcomings of using standard aluminum profile beams for the arc corner beams when converting straight curtain walls to tilted curtain walls, which makes it difficult to achieve the required torsional angle during processing and installation.

[0009] This invention employs a freely adjustable angle between a circular tube and a U-shaped pad frame. The connection between the U-shaped pad frame and the circular tube enables a beam connection structure with freely torsional angles. This solves the problem that when a curved glass curtain wall transitions from an incline to a straight line, a normal curved beam frame cannot meet the connection requirements when the glass curtain wall angle changes, thus achieving a freely variable angle connection between the curtain wall glass and the beam at curved corners.

[0010] The beneficial effects of this invention are: it enables the free angle torsion of the horizontal frame at the corner of the glass curtain wall, thus ensuring the safe installation of the inclined corner curtain wall glass. Attached Figure Description

[0022] This invention relates to an installation structure for glass curtain walls where they transition from a sloping curtain wall to a straight curtain wall at curved corners, such as... Figure 1 and 3 As shown, it includes inclined curtain wall section I, straight curtain wall section III, and curved area II from the inclined curtain wall to the straight curtain wall. In curved area II, the glass curtain wall transitions from inclined to straight. Figure 1 As can be seen from the cross-sectional diagram of section II: the curtain wall glass 1 is inclined at 75° and is connected to the shaped horizontal frame 8 through the horizontal curved steel tube frame 4.

[0023] like Figure 4 As shown, the installation system includes: the curtain wall glass 1 is a sandwich hollow curtain wall glass, the glass pressing U-groove 2 and the fiberglass pressure plate 3 are set in the sandwich layer, the curtain wall glass 1 is connected to the U-shaped steel pad frame 5 with a wide upper frame and a narrow lower frame through the glass pressing U-groove 2 and the fiberglass pressure plate 3, which can be freely adjusted in angle. The U-shaped steel pad frame 5 is fixed to the outside of the steel round tube horizontal frame 4, and is fixed to the shaped horizontal frame 8 through the horizontal frame steel plate adapter 6, so as to realize the inclined curtain wall with a hidden frame in the horizontal direction; the horizontal frame steel plate U-shaped piece 7 with multiple angles is fixed to the other side of the steel round tube horizontal frame 4 and connected to the shaped horizontal frame 8.

[0024] By utilizing the cylindrical surface of the steel tube horizontal frame 4 and the U-shaped steel pad frame 5 with freely adjustable angles, as well as the U-shaped parts of the horizontal frame steel plate 7 with multiple angles, the fixed positions can be smoothly adjusted. This solves the problem that when the curved glass curtain wall changes from inclined to straight, the normal horizontal frame cannot meet the connection requirements when the glass curtain wall angle changes, thus realizing the connection of the curtain wall glass.

[0025] like Figure 5 As shown, this is the installation system for a straight curtain wall, with a structure similar to... Figure 4 The structures shown are the same, both including: a glass pressing U-groove 2 and a fiberglass pressure plate 3 for fixing the curtain wall glass 1', which are connected to a U-shaped steel pad frame 5' with an adjustable angle. The upper and lower sides of the U-shaped steel pad frame 5' are of equal width and are fixed on the steel round tube horizontal frame 4. The U-shaped steel pad frame 5' with an adjustable angle is fixed to the shaped horizontal frame 8 through the horizontal frame steel plate adapter 6.

[0026] This invention relates to the connection of curved glass and curved horizontal frame at the corner of a glass curtain wall when transitioning from a tilted curtain wall to a straight curtain wall. The key technical points are: taking the horizontal curved steel tube as the design center, (1) the glass is designed with a concealed frame in the horizontal direction by pressing U-grooves, steel pressure plates and U-shaped steel pads that can be freely adjusted; (2) by welding U-shaped steel parts at various angles to the curved steel tube horizontal frame, the design concept of the glass curtain wall being able to change at multiple angles when transitioning from a tilted curtain wall to a straight curtain wall is achieved. This design has a simple structure and solves the problem that when the curved glass curtain wall at the corner changes from tilted to straight, the normal horizontal frame cannot meet the connection when the glass curtain wall angle changes. It utilizes the advantage that the steel tube horizontal frame can adapt to multiple angles after bending, and achieves the connection of the curtain wall glass by connecting U-shaped steel parts with different processing forms.
