Description

Technical Field

[0001] This utility model relates to glass curtain wall technology in the field of building structures, specifically to a glass curtain wall assembly structure based on Z-shaped connectors. Background Technology

[0002] Glass curtain walls, as a common facade structure in modern buildings, are widely used in modern large and high-rise buildings. They are mainly composed of panels and a supporting structural system, and thanks to their design flexibility and strong seismic performance, they can give buildings an aesthetically pleasing decorative effect.

[0003] In pursuit of a transparent and grand facade, the client demanded increasingly larger glass panel sizes for the curtain wall, resulting in individual glass panels often weighing over a thousand kilograms. The weight of the curtain wall glass is initially borne by the aluminum alloy beams, then transferred through the beams to the aluminum alloy columns, and finally to the curtain wall supports. Conventional curtain wall structural calculation software primarily focuses on bending, shear, and deflection control in the mechanical analysis of the aluminum alloy beams, often neglecting or underestimating the importance of accurate calculations of their actual torsional resistance. This can lead to situations where, although the overall structural stress analysis of the large-pane glass curtain wall passes smoothly and meets design requirements during calculation, the beams may twist during actual construction when the heavy glass is installed. This not only affects safety but may also damage the beam's flatness, potentially resulting in unevenness on the interior side and requiring extensive rework. To address this issue, the construction team needs to implement appropriate strategies to reduce the likelihood of torsion in the aluminum alloy beams. Specific measures included adding steel embedded plates and custom steel components to the central area at the bottom of the aluminum alloy beams to enhance the structure's support. While this strategy significantly improved structural stability, it also led to increased engineering costs.

[0004] If the torsional resistance of aluminum alloy beams can be considered during the design phase and their assembly structure can be improved, it will help to improve the overall performance of the curtain wall system without adding additional support components. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a glass curtain wall assembly structure based on Z-type connectors, which can solve the defects in the above-mentioned technical background.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A glass curtain wall assembly structure based on Z-type connectors, in which Z-type connectors are used as auxiliary reinforcing structural components to assemble the curtain wall glass between the structural frame and the outer buckle panel;

[0008] The structural frame includes columns and beams. Adjacent curtain wall glass panels in the longitudinal position are spliced ​​and assembled at the beam position, and adjacent curtain wall glass panels in the transverse position are spliced ​​and assembled at the column position. The outer buckle plate is used to fix the position of the curtain wall glass on the outside of the splicing position.

[0009] The Z-shaped connector includes a first horizontal side, a second horizontal side, and a vertical side. The two ends of the vertical side are respectively connected to one side of the first horizontal side and the opposite side of the second horizontal side to obtain a Z-shaped structure.

[0010] In the structural frame, the outer plane of the crossbeam is located behind the outer plane of the column, and the positional difference matches the length of the vertical side in the Z-shaped connector. A structural sub-frame is formed on the outer plane of the crossbeam, and the crossbeam fills the outer plane through the structural sub-frame to obtain a surface flush with the outer plane of the crossbeam. The Z-shaped connector is fitted and assembled with the outer plane of the column through the first horizontal side, inserted into the inner side of the structural sub-frame through the second horizontal side, and the structural sub-frame is then fitted and stacked with the outer plane of the crossbeam.

[0011] As a further limitation, the columns and beams that make up the structural frame are all made of aluminum alloy profiles, while the Z-shaped connectors are made of one-piece molded aluminum alloy profiles.

[0012] As a further limitation, the columns and beams of the structural frame are assembled and connected by a combination of angle brackets and threaded connectors.

[0013] As a further limitation, when adjacent curtain wall glass panels are spliced ​​at the crossbeam position, a combination of foam rods and sealant is used to fill the joint.

[0014] As a further limitation, the curtain wall glass is bonded and fixed to the aluminum alloy sub-frame in the horizontal beam direction using neutral silicone structural adhesive.

[0015] As a further limitation, the first horizontal edge of the Z-shaped connector is connected and fastened to the outer plane of the column, and the second horizontal edge is connected and fastened to the inner frame edge of the structural sub-frame and the outer plane of the beam by threaded connectors.

[0016] The columns are fitted with soft rubber strips as buffer material at the connection points corresponding to the first horizontal side. When the curtain wall glass is assembled on the surface of the columns, it is attached to the surface of the soft rubber strips to absorb and disperse the stress at the connection points and prevent the curtain wall glass from being scratched or broken.

[0017] As a further limitation, the structural components in the glass curtain wall assembly structure are connected by threaded connectors, and a flexible rubber pad is provided between the threaded connectors and the inner surface of the curtain wall glass as a buffer structure.

[0018] As a further limitation, the two folded edges of the Z-shaped connector are connected and transitioned using a right-angle structure.

[0019] Beneficial Effects: This utility model, a glass curtain wall assembly structure based on Z-shaped connectors, simplifies the construction process, reduces reliance on additional support components, and thus lowers project costs. By introducing Z-shaped connectors, this structure effectively optimizes the installation process of the curtain wall glass, utilizing less structural material and simpler fixing technology to effectively reduce the torsion problem of the aluminum alloy beams. It not only disperses the concentrated pressure of the glass weight on the beams but also establishes a stable support point between the beams and columns, effectively reducing or even completely eliminating the need for adding steel embedded plates and custom steel components at the bottom center of the beams. This ensures more effective protection of the beams' safety and flatness, is more economical, and avoids potential quality problems during later curtain wall maintenance, thereby reducing a significant amount of rectification work.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0027] See Figures 1-5A preferred embodiment of a glass curtain wall assembly structure based on Z-type connectors. In this embodiment, the glass curtain wall assembly structure consists of a structural frame, Z-type connectors 4, outer buckle panels, and curtain wall glass 6. The structural frame includes columns 1 and beams 2, while the outer buckle panels include pressure plates 7 and buckle covers 8.

[0028] The column 1 is a one-piece molded rectangular tubular profile. A protrusion is pre-drilled on the lower side of the column 1, and the outer buckle plate can be secured at this protrusion by the combination of the pressure plate 7 and the connecting screw 10. Figure 1 The curtain wall glass 6 is assembled in the manner shown, thereby achieving a fixed assembly; while the cover 8 is used to cover the outside of the pressure plate 7 to obtain a visible frame decorative effect.

[0029] The body of the crossbeam 2 has a slot on its right side, and the slotted surface is covered by the crossbeam cover 14. The crossbeam 2 has a pre-reserved assembly position on its lower side for fitting with the sub-frame pressure block 13. Figure 2 The end face assembly of the structural sub-frame 11 is performed according to the pattern shown.

[0030] The column 1, beam 2, beam cover 14, sub-frame pressure block 13, structural sub-frame 11 cover 8 and pressure plate 7 are all made of aluminum alloy profiles.

[0031] The Z-type connector 4 is a one-piece molded Z-shaped aluminum alloy profile structure, which has a first horizontal side, a second horizontal side, and a vertical side. The two ends of the vertical side are respectively connected to one side of the first horizontal side and the opposite side of the second horizontal side to obtain the Z-shaped structure. The two folded edges of the Z-type connector 4 are connected and transitioned using a right-angle structure. Before leaving the factory, the Z-type connector 4 has threaded holes formed on the first horizontal side and the second horizontal side to facilitate mating assembly.

[0032] The curtain wall glass 6 uses 10+12A+10mm thick tempered insulated glass.

[0033] The curtain wall system assembled using this glass curtain wall assembly structure is a vertically exposed and horizontally concealed glass curtain wall system. The basic installation process of the entire glass curtain wall system and Z-type connector 4 is as follows:

[0034] 1. Effectively connect and fix column 1 to the main building structure;

[0035] 2. The beam 2 is connected to the column 1 via aluminum alloy corner brackets 3 on its flat side. The connection method involves inserting three connecting bolts 10 from the open side of the beam 2 to complete the connection, as shown in the diagram. Figure 1 As shown, the crossbeam cover 14 is then fastened to the open side surface of the crossbeam 2 to cover the connecting screw 10 and ensure aesthetics.

[0036] 3. After the column 1 and the crossbeam 2 are adjusted to be horizontal and vertical, the Z-type connector 4 is set at the junction of the two. The threaded hole on the first horizontal side of the Z-type connector 4 is fixed to the column 1 with connecting screws 5 (avoid the screw head from contacting the inside of the glass). The threaded hole on the second horizontal side of the Z-type connector 4 is fixed to the crossbeam with connecting screws 5.

[0037] 4. After pressing the EPDM rubber strip 9 (EPDM rubber strip 9 can be a press-fit type for easy on-site construction) into the grooves of the column 1 and the pressure plate 7, install the curtain wall glass 6. Vertically, press the glass tightly with the pressure plate 7 and fix it with connecting screws 10 at the specified spacing. Horizontally, press the structural sub-frame 11 tightly with the sub-frame pressure block 13. Fill and bond the gap between the structural sub-frame 11 and the curtain wall glass 6 with neutral silicone structural adhesive 15. At the same time, fix the structural position with connecting screws 10 at the specified spacing.

[0038] 5. Vertically snap the cover 8 to the pressure plate 7;

[0039] 6. Apply weather-resistant sealant to both vertical and horizontal gaps. For vertical gaps, apply the sealant directly. For horizontal gaps, insert foam rods first to fill the gaps, then apply the sealant to the foam rods to seal them, achieving the desired effect. Figure 2 The weather-resistant sealant 12 shown is used as a structural sealant in combination with a foam rod.

[0040] Under the structural conditions of this embodiment, the curtain wall system is a vertically exposed and horizontally concealed glass curtain wall system. Its main load-bearing mechanism is achieved by using neutral silicone structural adhesive 14 to firmly bond and transfer force to the structural sub-frame 11 in the horizontal direction of the insulated glass 6. Subsequently, the structural sub-frame 11 is tightly pressed together by sub-frame pressure blocks 13 and then fixed with stainless steel machine screws 10, ensuring that the weight of the glass can be effectively transferred to the horizontal beam 2. Then, the weight is transferred from the horizontal beam 2 to the columns 1, and finally reaches the supports of the glass curtain wall.

[0041] In this embodiment, by setting the Z-shaped connector 4, the torsion of the horizontal beam 2 after the glass curtain wall is assembled and installed can be effectively reduced, and the need to add steel embedded plates and customized steel parts as auxiliary supports at the bottom middle position of the horizontal beam 2 can be reduced or eliminated. In this way, both engineering material and labor costs can be effectively reduced.
