Curtain wall structure with large cantilevered shaped members

Abstract

The application discloses a curtain wall structure with a large cantilevered shaped member, which can more efficiently transfer loads to the main structure when applied to a building curtain wall cantilevered shaped structure to bear loads, ensures the stability of the structure after the cantilevered shaped structure bears loads, and adopts bolt connection between the cantilevered shaped member and the supporting batten of the curtain wall, so that appropriate displacement can be generated after the structure bears loads, and stress concentration phenomenon is eliminated. The cantilevered shaped member is connected with interlayer columns through upper and lower assemblies respectively, instead of rigid connection with the cross beam, and the path of load transmission from the cantilevered shaped member to the horizontal secondary batten at the upper and lower compartments is cut off, so that the probability of damage of the curtain wall glass is reduced, and the safety during construction is ensured. The application solves the problem that the curtain wall system is damaged due to stress concentration when a large cantilevered shaped decorative structure is added at the interlayer position of the curtain wall.

Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a curtain wall structure with large cantilevered structural members. Background Technology

[0002] Curtain wall decoration, with its excellent shaping capabilities and decorative effects, provides architects with more room for creativity and is favored by architects in modern architecture.

[0003] Modern architectural styles are highly imaginative, and to achieve better facade effects, they are no longer simply geometric planes. Therefore, the implementation of curtain wall projects continues to face challenges. When large cantilevered decorative elements are incorporated between curtain wall floors, ensuring the straightness and overall aesthetics of these elements while effectively transferring the load and preventing stress concentration that could damage the curtain wall system is a current problem that urgently requires a structural solution.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, a curtain wall structure with large cantilevered decorative elements is provided to solve the problem that stress concentration can easily occur and cause damage to the curtain wall system when large cantilevered decorative structures are added between curtain wall layers.

[0006] To achieve the above objectives, a curtain wall structure with large cantilevered structural members is provided, comprising:

[0007] The building structure's floor slabs extend outwards to form cantilevered floor slabs, and the curtain wall structure with large cantilevered structural elements includes:

[0008] A multi-layered support keel is arranged vertically and installed on the exterior facade of the building structure. A gap is formed between two adjacent layers of support keels. The cantilevered floor slab is aligned with the upper part of the gap. Multiple inter-layer columns are vertically arranged along the circumferential direction of the building structure on the upper part of the lower layer of support keel. The inter-layer columns extend to the upper part of the gap.

[0009] A cantilevered decorative element is provided on the outside of the gap. The upper part of the inner side of the cantilevered decorative element is connected to the cantilevered floor slab by multiple upper-level components. The middle part of the upper-level components is connected to the upper part of the inter-floor column. The lower part of the cantilevered decorative element is connected to the lower part of the inter-floor column by a lower-level component.

[0010] The curtain wall glass is installed on the outside of the supporting keel. The lower curtain wall glass of the supporting keel is supported by the lower part of the cantilevered decorative element, and the lower part of the upper curtain wall glass of the supporting keel abuts against the upper part of the cantilevered decorative element.

[0011] Furthermore, a pre-embedded plate is embedded in the cantilevered floor slab. The pre-embedded plate includes a first flange and a second flange arranged vertically. The first flange is connected to the second flange and is embedded in the outer side of the cantilevered floor slab. The second flange is embedded in the bottom of the cantilevered floor slab. The upper component is connected to the first flange. Anchor bars embedded in the cantilevered floor slab are respectively connected to the first flange and the second flange. The anchor bars on the first flange and the anchor bars on the second flange are arranged to cross each other.

[0012] Furthermore, the upper-layer component includes:

[0013] Two upper clamping beams, one end of which is connected to the upper part of the inner side of the cantilevered structural member, and the other end of which is connected to the first flange. The two upper clamping beams are respectively attached to the opposite sides of the upper part of the inter-story column.

[0014] The first tie member is installed on the upper part of the inter-story column and tied to the two upper clamping beams.

[0015] Furthermore, a groove is formed on the upper part of the inner side of the cantilevered member, and a support member is held between one end of the two upper clamping beams, with the support member embedded in the groove.

[0016] Furthermore, the lower-level component includes:

[0017] Two lower clamping beams, one end of each lower clamping beam is attached to the opposite sides of the lower part of the inter-story column, and the other end of each lower clamping beam is connected to the lower part of the inner side of the cantilevered structure.

[0018] The second tie member is installed at the lower part of the inter-story column and tied to one end of the two lower clamping beams.

[0019] Furthermore, the cantilevered structural member includes a top plate and a bracing plate. The top plate is arranged horizontally and has a first side close to the supporting keel and a second side away from the supporting keel. The upper component is connected to the first side of the top plate. The bracing plate is arranged at an angle, with its upper end connected to the second side of the top plate and its lower end extending inward and downward to the lower part of the inter-layer column. The lower component is connected to the lower end of the bracing plate.

[0020] Furthermore, the supporting keel includes multiple vertical columns and horizontal beams. The vertical columns are installed on the building structure and located on the outside of the cantilevered floor slab. The multiple vertical columns are arranged along the circumferential direction of the building structure, and multiple horizontal beams connect adjacent vertical columns.

[0021] The beneficial effects of this invention are as follows: the curtain wall structure with large cantilevered components, when applied to the cantilevered structure of a building curtain wall to bear loads, can more efficiently transfer the load to the main structure, ensuring structural stability at the cantilevered section under stress. The bolted connection between the cantilevered component and the supporting joists of the curtain wall ensures appropriate displacement after the structure bears the load, eliminating stress concentration. The cantilevered component is connected to the inter-story columns via upper and lower components, replacing a rigid connection with the horizontal beams. This cuts off the path for the load transferred from the cantilevered component to the horizontal secondary joists at the upper and lower dividing points, thereby reducing the probability of curtain wall glass damage and ensuring construction safety.

[0028] Reference Figures 1 to 3 As shown, the present invention provides a curtain wall structure with a large cantilevered component, including: a supporting keel 1, a cantilevered component 2, and curtain wall glass 3.

[0029] Specifically, the multi-layered supporting keel 1 is arranged vertically. The supporting keel 1 includes multiple vertical columns 11 and horizontal beams 12.

[0032] The curtain wall glass 3 is installed on the outside of the supporting keel 1. The curtain wall glass 3 of the lower supporting keel 1 is supported by the lower part of the cantilevered structural member 2. The lower part of the curtain wall glass 3 of the upper supporting keel 1 abuts against the upper part of the cantilevered structural member 2.

[0033] In this embodiment, an embedded plate is provided in the cantilever floor slab 4. Specifically, the embedded plate includes a vertically arranged first flange 41 and a second flange 42. The first flange 41 is connected to the second flange 42. The first flange 41 is embedded in the outer surface of the cantilever floor slab 4. The second flange 42 is embedded in the bottom of the cantilever floor slab 4. The upper component 5 is connected to the first flange 41. Anchor bars embedded in the cantilever floor slab 4 are respectively connected to the first flange 41 and the second flange 42. The anchor bars on the first flange 41 and the anchor bars on the second flange 42 are arranged intersectingly.

[0034] In a preferred embodiment, each upper component 5 includes two upper clamping beams 51, a first tie member 52, and a support member 53.

[0035] Two upper clamping beams 51 are provided, with one end of each beam connected to the upper inner side of the cantilevered structural member 2. The other end of each beam is connected to the first flange 41. The two upper clamping beams 51 are respectively attached to the opposite sides of the upper part of the inter-story column.

[0036] The first tie member 52 is installed on the upper part of the inter-story column and is tied to the two upper clamping beams 51.

[0037] A groove is formed on the upper inner side of the cantilevered member 2. A support member 53 is held between one end of the two upper clamping beams 51. The support member 53 is embedded in the groove.

[0038] In a preferred embodiment, each lower component 6 includes two lower clamping beams 61 and a second tie member 62.

[0039] One end of each of the two lower clamping beams 61 is attached to the opposite sides of the lower part of the inter-story column. The other end of each of the two lower clamping beams 61 is connected to the lower part of the inner side of the cantilevered structural member 2.

[0040] The second tie member 62 is installed at the bottom of the inter-story column and is tied to one end of the two lower clamping beams 61.

[0041] The cantilevered structural member 2 includes a top plate 21 and a diagonal brace 22. The top plate 21 is arranged horizontally. The top plate 21 has a first side close to the supporting joists 1 and a second side away from the supporting joists 1. The upper assembly 5 is connected to the first side of the top plate 21. The diagonal brace 22 is arranged at an angle. The upper end of the diagonal brace 22 is connected to the second side of the top plate 21. The lower end of the diagonal brace 22 extends inward and downward to the lower part of the inter-story column. The lower assembly 6 is connected to the lower end of the diagonal brace 22.

[0042] During construction, after verifying the position and elevation of the embedded parts in the pre-embedded plate, one end of each of the two upper clamping beams is welded to the first flange of the pre-embedded plate. The inter-story column is installed between the two upper clamping beams, and the inter-story column is connected to the two upper clamping beams via the first tie rod (tie bolts and nuts) to ensure load-bearing requirements. The other end of each of the two upper clamping beams is bolted to the support member. A section of angle steel is connected to the support member. The angle steel and the support member are embedded in a notch formed on the first side of the top of the cantilevered structural member.

[0043] Two lower clamping beams are held in place at the bottom of the inter-story column and connected together by a second tie rod (tie bolts + nuts). An angle steel is welded to the other end of the two lower clamping beams to connect to the lower part of the diagonal bracing plate of the cantilevered structure, so as to satisfy the anchoring of the inner lining skeleton on the inner side of the cantilevered structure and the adjustment of its horizontal position.

[0044] Complete the welding and installation of the inner lining keel of the cantilevered structure, and set isolation materials between different multi-layer materials to prevent electrochemical corrosion.

[0045] The cantilevered structural member is equipped with a drip edge, which is fixed to the upper and lower supporting keels with screws and sealed with sealant, thus connecting with the upper and lower waterproofing systems to form an effective waterproofing system.

[0046] Rock wool insulation boards are installed behind the drip edge, and galvanized steel sheets are used for sealing on the interior side to ensure the overall energy-saving and thermal insulation requirements of the curtain wall. Fireproof sealing is installed between floors to meet the fire protection requirements of the code.

[0047] The curtain wall structure with large cantilevered components of this invention, when applied to the cantilevered structure of a building curtain wall to bear loads, can more efficiently transfer the load to the main structure, ensuring structural stability at the cantilevered section under stress. The cantilevered components are bolted to the supporting joists of the curtain wall, ensuring appropriate displacement under load and eliminating stress concentration. The cantilevered components are connected to the inter-story columns via upper and lower components, replacing rigid connections to the horizontal beams. This cuts off the path for the load from the cantilevered components to be transferred to the horizontal secondary joists at the upper and lower dividing points, thereby reducing the probability of curtain wall glass damage and ensuring construction safety.
