Description

Technical Field

[0001] This invention belongs to the technical field of glass curtain wall connection structure, and specifically relates to a multi-curvature glass curtain wall connection structure and construction method. Background Technology

[0002] In the field of building curtain walls, glass curtain walls are the most common type of curtain wall. Due to their transparency and good performance, they are widely used in various building exterior curtain walls, with curved glass being particularly aesthetically pleasing. However, most framed glass curtain walls, whether concealed or exposed, generally use a column and beam structure to construct the curtain wall support system in order to ensure the performance and overall strength of the glass curtain wall.

[0003] The presence of a keel always affects the appearance, disrupting the transparency and integrity of the glass curtain wall at the keel location. In addition, to match the curvature of the glass curtain wall, curved beams need to be fabricated, making the preliminary preparation work cumbersome. Furthermore, some existing multi-curvature glass curtain walls often use large-area, extra-large curved glass to improve transparency, which reduces safety. Summary of the Invention

[0004] To improve the transparency, continuity, and integrity of multi-curvature glass curtain walls, and to avoid using ultra-large curved glass, thereby enhancing the safety of glass curtain walls, this invention provides a connection structure and construction method for multi-curvature shaped glass curtain walls.

[0021] Furthermore, a support assembly is provided at the bottom of the lowest curved glass layer to support it; and / or,

[0022] The supporting component is provided with several baffles on the side facing the building exterior, and the several columns are spaced apart between the steel beams and the pre-embedded plate on the ground inside the building.

[0023] The support components include:

[0024] A supporting square tube is installed on top of a pre-embedded plate in the ground to support the multi-curvature glass curtain wall.

[0025] The L-shaped support is located at the top of the support square tube and is used to support the bottom layer of curved glass.

[0026] A plurality of U-shaped connectors are provided, with their openings facing downwards at the bottom of the L-shaped support. Each baffle is provided on one of the U-shaped connectors, so that the L-shaped support and the baffle cooperate to form a U-shaped mounting and limiting groove structure to limit the bottom of the lowest curved glass.

[0027] Furthermore, a limiting square tube is provided between two adjacent columns to fit and limit the top side of the uppermost curved glass facing the interior; and / or,

[0054] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0055] Example 1:

[0056] refer to Figures 1 to 5 This embodiment provides a multi-curvature glass curtain wall connection structure, including: several layers of curved glass groups, several columns 2, several support plates 3, and fixing components.

[0057] Several layers of curved glass are arranged sequentially along the building height to form a multi-curvature glass curtain wall. Each layer of curved glass includes several curved glass 1 arranged sequentially along the direction perpendicular to the building height.

[0058] Several columns 2 are spaced apart and installed inside the building. The columns 2 can be made of steel square tubing. The columns 2 are spaced apart between the steel beams 16 and the pre-embedded ground plate 17 inside the building. The top of each column 2 is fixed to the steel beam 16 via a connector 14. The connector 14 can be welded to the steel beam 16. A reinforcing steel plate can be welded between the side of the connector 14 and the column 2 to reinforce the connector 14. The connector 14 and the column 2 can be fixed together with bolts. The bottom of each column 2 is welded to the pre-embedded ground plate 17, and a second stiffening rib 15 is provided between the column 2 and the pre-embedded ground plate 17. Three second stiffening ribs 15 can be welded to each side of the column 2 to reinforce the column 2 and improve its stability.

[0059] Each support plate 3 is used to be installed on a column 2. Several support plates 3 are used to connect two adjacent curved glass groups and support the curved glass group located above the support plate 3. The support plate 3 is sandwiched between two adjacent curved glass groups, so that a gap with the same thickness as the support plate 3 is formed between the two curved glass groups. The gap between the two adjacent curved glass groups can be filled with sealant, so that the curved glass groups form a whole. The support plate 3 is welded to the side of the column 2 facing the outside. First stiffening ribs 4 are welded between the upper surface of the support plate 3 and the column 2, and between the lower surface of the support plate 3 and the column 2, to reinforce the support plate 3 and improve its stability.

[0060] The fixing component is used to fix the side of the curved glass 1 to the column 2, so as to connect two adjacent curved glass 1s on the left and right.

[0061] The multi-curvature glass curtain wall connection structure in this embodiment uses a support plate 3 and fixing components on the columns 2 to fix the curved glass 1. The support plate 3 directly transfers the gravity load of the glass to the columns 2, replacing the traditional beam structure. This greatly improves the transparency, continuity, and integrity of the glass curtain wall, while ensuring aesthetics. It allows multiple glass panels to appear as a single, integrated piece, avoiding the need for oversized single glass panels, improving safety, and reducing the difficulty of glass hoisting. Furthermore, the absence of curved beams in the initial preparation work avoids errors, simplifies the process, and reduces processing costs. The optimized steel frame system, eliminating beams and strengthening the columns 2, reduces the number and complexity of installation steps.

[0062] As a preferred embodiment, the fixing component includes a base 501 and a pressure plate 502. The base 501 and the pressure plate 502 can be made of aluminum alloy, which is lightweight and has high strength, meeting the usage requirements.

[0063] The base 501 is located on the outdoor-facing side of the column 2 and is used to install the curved glass 1 and limit the indoor side of the curved glass 1. The base 501 can be fixed to the column 2 with machine screws, and a flexible gasket can be placed between the base 501 and the column 2 to prevent wear between them. When the arc length of the curved glass 1 is greater than 2700mm, a limiting member 6 for limiting the side of the curved glass 1 along the building height direction can be fixed to the base 501 with self-tapping screws. Structural adhesive can also be placed between the limiting member 6 and the side of the curved glass 1 to limit the glass and prevent it from moving left and right. For curved glass, it can be limited on only one side and not on the other side, or it can be limited on both sides.

[0064] The pressure plate 502 is mounted on the base 501 by screws and is used to limit the side of the curved glass 1 facing the outside. After the screws are tightened to press the pressure plate 502 against the base 501, the curved glass 1 is fixed. The screws pass through the pressure plate 502 and connect to the base 501. One side of the pressure plate 502 presses against one curved glass 1, and the other side of the pressure plate 502 presses against another curved glass 1.

[0065] Adhesive strips 7 are provided between the base 501 and the curved glass 1, and between the pressure plate 502 and the curved glass 1, to protect the surface of the curved glass 1 and prevent damage to the surface of the curved glass 1 when the pressure plate 502 is pressed.

[0066] As a preferred embodiment, two subframes 8 are symmetrically arranged on the base 501. The subframes 8 can be made of aluminum alloy and can be fixed to the base 501 by self-tapping screws. A first decorative cover plate 9 is arranged between the two subframes 8 and surrounds the outer ring of the column 2. The first decorative cover plate 9 can be a mirror stainless steel plate. An aluminum honeycomb lining plate can be provided on the inner wall of the first decorative cover plate 9 to improve the strength of the first decorative cover plate 9.

[0067] A second decorative cover plate 10 is provided on the side of the pressure plate 502 facing the outside. The second decorative cover plate 10 can be a mirror stainless steel plate. The first decorative cover plate 9 and the second decorative cover plate 10 form an elliptical cross-sectional shape inside and outside the glass curtain wall, making the joint of the adjacent curved glass 1 on the left and right sides more aesthetically pleasing.

[0068] The joints between the first decorative cover plate 9 and the curved glass 1, and between the second decorative cover plate 10 and the curved glass 1, can be sealed with sealant to prevent rainwater, dust, and other impurities from entering the interior of the decorative cover plate.

[0069] In a preferred embodiment, a support assembly is provided at the bottom of the lowest curved glass 1 to support the lowest curved glass 1. Several baffles 11 are provided on the side of the support assembly facing the exterior of the building, and several columns 2 are spaced apart between the steel beams 16 and the embedded plate 17 in the building interior.

[0070] The support components include: a support square tube 1201, an L-shaped support member 1202, and several U-shaped connectors 1203.

[0071] The supporting square tube 1201 is installed on the top of the ground embedded plate 17 to support the multi-curvature glass curtain wall.

[0072] L-shaped support 1202 is installed on the top of support square tube 1201 to support the bottom curved glass 1. The L-shaped support 1202 is arc-shaped along the direction perpendicular to the building height, and the curvature is the same as the curvature of the curved glass 1 it supports, thus limiting the curved glass 1 in the horizontal direction.

[0073] Several U-shaped connectors 1203 with their openings facing downwards are disposed at the bottom of the L-shaped support 1202. Each baffle 11 is disposed on a U-shaped connector 1203. The U-shaped connectors 1203 can be welded to the bottom of the L-shaped support 1202. The baffle 11 can be fixed to the side of the U-shaped connector 1203 facing the exterior of the building by bolts, so that the L-shaped support 1202 and the baffle 11 cooperate to form a U-shaped installation limiting groove structure to limit the bottom of the bottom layer of curved glass 1.

[0074] In a preferred embodiment, a limiting square tube 13 is provided between two adjacent columns 2 to fit and limit the top side of the uppermost curved glass 1 facing the interior. The limiting square tube 13 is arc-shaped and has the same curvature as the curved glass 1. Sealant can be filled between the arc-shaped square tube and the curved glass 1 to improve the sealing performance of the glass curtain wall.

After all the glass is in place, install the pressure plate 502 on the base 501 to fix the sides of the glass vertically to the building height direction. Seal the joints between adjacent curved glass 1 pieces. When installing the curved glass 1, the bottom of each curved glass 1 piece in the bottom layer is placed on the L-shaped support 1202 and fixed on both sides by the base 501 and the pressure plate 502. The bottom of each curved glass 1 piece in the middle layer is placed on the support plate 3 and fixed on both sides by the base 501 and the pressure plate 502. The bottom of each curved glass 1 piece in the top layer is placed on the support plate 3 and fixed on both sides by the base 501 and the pressure plate 502.
