Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular to a joint structure between a glass curtain wall and the main structure. Background Technology

[0002] Traditional glass curtain wall expansion joints are designed to cope with thermal expansion and contraction or structural deformation caused by temperature changes, wind loads, earthquakes, etc., ensuring the safety and airtightness of the curtain wall system. Currently, common expansion joint types include: 1. Open joint structure: A gap of a certain width (usually 10-30mm) is reserved between curtain wall units, without filling with rigid materials, and the surface is covered with elastic sealant (such as silicone sealant); this joint structure is suitable for areas with large temperature differences or requiring large displacement adjustment, but its aesthetics are poor. 2. Elastic filling joint: Elastic materials such as rubber strips, foam rods, and polyurethane are used to fill the gap, and the surface is then sealed with sealant; this joint material is prone to aging; the joint displacement adjustment capacity is limited, with conventional designs only adapting to 10-30mm of expansion and contraction, and the elastomer is prone to breakage when the deformation exceeds 50%; construction quality control is difficult, requiring strict control of the substrate moisture content (≤20%), but in actual construction, weather conditions or tight deadlines often make it difficult to meet the standard, leading to a decrease in the bonding strength between the epoxy primer and the elastomer. 3. Metal Cover Plate Joints: Sliding metal covers (such as aluminum alloy or stainless steel) are installed at the joints, connected by clips or sliding rails, allowing horizontal or vertical displacement. The drawbacks of this type of joint include a significant risk of leakage: traditional overlapping + structural adhesive sealing methods are prone to cracking due to temperature stress; complex mechanical structure: the sliding clip / rail system is sensitive to installation errors (allowable deviation is only ±2mm), and misaligned columns require additional connectors, increasing construction difficulty. 4. Concealed Joints: The joints are concealed through the staggered or overlapping design of the curtain wall panels, with internal elastic support components. This joint structure has stringent construction precision requirements: panel misalignment errors must be controlled within ±1mm (normally ±3mm is allowed), otherwise the internal elastic support components will be exposed; high maintenance difficulty: damage to the internal elastic support components requires removal of the decorative panels for repair; and weak displacement compensation capability: the concealed design limits the width of the expansion joint, making it difficult to adapt to the deformation needs of large-span buildings.

[0003] In summary, the core function of the aforementioned curtain wall expansion joints is to balance structural deformation and sealing, but their defects, such as easy aging of materials, poor aesthetics, strong dependence on construction, and limited displacement capacity, are gradually being exposed. Utility Model Content

[0004] The purpose of this utility model is to provide a joint structure between a glass curtain wall and the main structure, in order to solve the technical problems of traditional expansion joint structures, such as easy aging of materials, poor aesthetics, strong dependence on construction, and limited displacement capacity.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A joint structure between a glass curtain wall and a main structure is provided, located between the wall of the main structure and the glass curtain wall; it includes an arc-shaped plate, elastic strips, an inner sealing plate, and an outer decorative panel; a column is provided on the side of the joint near the glass curtain wall; the column is located at the inner end of the glass curtain wall, and the glass curtain wall is connected to the column; the arc-shaped plate is located between the end of the wall and the glass curtain wall; the horizontal cross-section of the inner sealing plate is wavy, located between the wall and the column, and a gap is provided between the inner sealing plate and the arc-shaped plate; a first layer of rock wool is filled in the gap between the inner sealing plate and the arc-shaped plate; a set of elastic strips is arranged vertically at intervals on the outside of the arc-shaped plate; an installation plate is connected to the outside of the elastic strips by a first bolt; the outer decorative panel is located on the outside of the installation plate, and the outer decorative panel is connected to the installation plate by fasteners.

[0007] Preferably, the wall includes an outer leaf plate, a rock wool board, and an inner leaf plate.

[0008] Preferably, a first connecting plate is provided at the end of the glass curtain wall and at the two ends of the corresponding curved plate on the wall; the curved groove of the curved plate is set outward, and the two ends of the curved plate are bent laterally to form a folded plate segment; the folded plate segment is fixed to the first connecting plate by a pressure plate; a slot is provided on the side of each pressure plate near the expansion joint; a locking strip is provided at both ends of the elastic strip; the locking strip is locked in the slot.

[0009] Preferably, the exterior panel includes a horizontal section and a side section; the side section is disposed on the inner sides of both ends of the horizontal section, and the inner ends of the side section are bent to form a connecting section; both ends of the mounting plate are respectively pressed onto the connecting sections on both sides; there is a set of first bolts, which are vertically spaced between the mounting plate and the elastic strip.

[0010] Preferably, a second connecting plate is provided on the column and the wall at both ends corresponding to the inner sealing plate; the inner sealing plate pressure plate overlaps the second connecting plate and is fixed by a second bolt; a pad is provided between the inner sealing plate and the second bolt.

[0011] Preferably, the glass curtain wall, joints, and inner side of the wall are provided with an insulation layer; a structural column is provided on the inner side of the insulation layer at the corresponding joint position; the structural column is connected to the insulation layer.

[0012] Compared with the prior art, the present invention has the following features and beneficial effects.

[0013] 1. The inner sealing plate, elastic strips, and curved plate of this utility model have a synergistic expansion and contraction effect: The vertically spaced elastic strips (such as EPDM or silicone rubber) combined with the structural design of the curved plate and inner sealing plate form a multi-level deformation buffer mechanism, which can accommodate displacements of ±50mm or more. Compared with traditional elastic filling joints, which can only cope with expansion and contraction of 10-30mm, the displacement compensation capacity of this structure is improved by about 60%, making it particularly suitable for curtain wall systems in super high-rise buildings or seismically active areas.

[0014] 2. The split exterior panel design of this utility model, where the exterior panel is connected to the elastic strip by bolts via an mounting plate, allows for horizontal sliding and vertical fine-tuning, achieving three-dimensional displacement compensation and reducing sensitivity to construction errors. Compared to the ±2mm installation accuracy required for traditional metal cover plate joints, this structure allows for deviations to be increased to ±5mm, significantly simplifying construction.

[0015] 3. The slot-type elastic strip and pressure plate fixing design of this utility model (the strip is embedded in the slot) enables quick disassembly and replacement. Simultaneously, the pre-embedded design of the first and second connecting plates, combined with bolt fixing, allows for factory prefabrication and rapid on-site assembly. Furthermore, the mounting plate of this utility model uses the first bolt to achieve fine-tuning and positioning of the exterior panel. Combined with the folded section design of the curved plate, it can compensate for construction errors in the main structure and reduce rework rates. Attached Figure Description
