Description

Technical Field

[0001] The present invention relates to the technical field of curtain wall installation, and in particular to a glass curtain wall structure with a deformation joint at a corner and a construction method thereof. Background Art

[0002] To prevent stresses generated by building deformation from causing cracking, damage, or functional failure, deformation joints (including expansion joints, settlement joints, and seismic joints) are required at specific locations. The design of curtain wall structures with deformation joints at corners is a key challenge for building envelope systems. This stems from the core contradiction between the complex, multi-dimensional deformations faced by the building structure at corners and the need to maintain the integrity of the curtain wall system. When a building undergoes thermal expansion and contraction, differential settlement, earthquakes, or wind loads, corners act as points of sudden change in structural stiffness. These joints can experience not only significant horizontal displacement (in both X and Y directions), but also vertical slip (settlement) or torsional deformation. Conventional curtain wall structures are prone to panel cracking, keel twisting, or connection failure due to rigid constraints at these locations. This can lead to ruptures in the sealing system, serious leakage, thermal bridging, and safety hazards. Furthermore, the complex structure often significantly impacts the uniformity of the curtain wall (especially glass curtain walls), disrupting the harmonious appearance of the building.

[0003] Chinese utility model patent CN222044646U (publication date November 22, 2024) discloses a composite curtain wall special-shaped corner structure, including keel assemblies arranged on both sides of the building structure corner, accordion plates connected between the two groups of keel assemblies, a first folding plate installed on one group of keel assemblies, and a second folding plate installed on the other group of keel assemblies, the first folding plate being bent to the inner side of the second folding plate at one end close to the second folding plate; a fixing piece is installed at the end of the second folding plate; the keel assembly includes two vertical keels and an aluminum plate frame connected to the vertical keels, and the first folding plate and the second folding plate are installed on the corresponding aluminum plate frame. It is closed by installing an accordion plate between the two groups of keel assemblies, and at the same time, the first folding plate and the second folding plate are slidably matched to adapt to the displacement and deformation generated at the deformation joint, thereby ensuring the structural stability of the aluminum plate curtain wall. However, it is only applicable to curtain walls and aluminum plate composite curtain walls. When used for glass curtain walls, the aluminum plate at the deformation joint greatly destroys the integrity of the facade.

[0004] Chinese utility model patent CN211396177U (publication date September 1, 2020) discloses a corner mounting structure for a glass curtain wall expansion joint, comprising two glass panels mounted on two mutually perpendicular building main body walls, a mounting member fixedly mounted on the end face of the glass panel close to the expansion joint, a sliding member slidingly connected to the mounting member along the length direction of the mounting member and closing the connection between the two glass panels, and an elastic water retaining plate fixedly connected to the two mounting members at both ends and located on the inner side of the sliding member, wherein the building wall is vertically fixed with a rectangular column, and the glass panel is mounted on the column. Although this prior art has a good sealing and waterproofing effect, its node structure is simple and the deformation space is small. It is only applicable to expansion joints and cannot adapt to the larger deformation of other types of deformation joints. In addition, there are few insulation measures, making it difficult to meet energy-saving requirements.

[0005] In the existing technology, the node structure of the deformation joints at the corners of glass curtain walls still needs to be improved. How to increase the deformation amount of the node structure of the glass curtain wall at the corners to adapt to different types of deformation joints while reducing the impact on the facade effect is still a problem that needs to be solved urgently. Summary of the Invention

[0006] The present invention addresses the problem in the prior art that the deformation of the node structure of the glass curtain wall at the corner cannot adapt to the multi-directional deformation at different types of deformation joints, and at the same time has a significant impact on the facade effect. The present invention provides a glass curtain wall structure with deformation joints at the corners, which can adapt to the displacement and deformation generated at different types of deformation joints.

[0007] A glass curtain wall structure with a deformation joint at a corner, comprising glass curtain walls arranged perpendicular to each other on both sides of the building deformation joint, mounting components respectively connected to the glass curtain walls, and an accordion plate connected between the two sets of mounting components;

[0008] It also includes a first folding plate installed on one group of mounting components and a second folding plate installed on the other group of mounting components. The accordion plate is L-shaped with an angle. The first folding plate and the second folding plate are interlocked at the bent ends and are staggered and spliced on the outside of the accordion plate. The two can slide, and a seal is provided at the gap.

[0009] Furthermore, both sides of the L-shaped accordion board are provided with retractable bending parts, and the ends of the accordion board are provided with protrusions.

[0010] Optionally, the L-shaped accordion plate is integrally molded from high-elasticity TPU or EPDM rubber.

[0011] Furthermore, the bend at one end of the first folding plate is clamped to the installation component, and the bend at one end of the second folding plate is clamped to another set of installation components, so that the installation gap is blocked.

[0012] Furthermore, the installation assembly includes an aluminum alloy column, a fixing piece and a connecting piece, wherein the fixing piece is fixedly connected to the aluminum alloy column; the connecting piece is provided with a buckling portion, which is buckled with the first groove of the aluminum alloy column.

[0013] Furthermore, the fixing member is provided with a second groove, and the protrusion at one end of the accordion plate is engaged with the second groove.

[0014] Furthermore, a rock wool board is provided in the gap between the aluminum alloy column and the main structural member. The thickness of the rock wool board is 100 mm. The outer side of the rock wool board is covered with a hot-dip galvanized steel plate. The galvanized steel plate is fixedly connected to the aluminum alloy column and the main structural member respectively.

[0015] Furthermore, the thickness of the hot-dip galvanized steel plate is 1.5 to 2 mm.

[0016] Furthermore, a V-shaped aluminum plate is provided at the deformation joint of the main structural member, and its two ends are respectively fixed to the main structural member.

[0017] Furthermore, a decorative cover is provided on the outdoor side facing the aluminum alloy column, and the decorative cover includes a mounting portion and a decorative portion. The mounting portion is fixedly connected to the aluminum alloy column, and the decorative portion is buckled to the mounting portion. The mounting portion covers the end of the first folding plate or the second folding plate, and sealant is provided at the gap.

[0018] The present invention also provides a construction method for a glass curtain wall structure with a deformation joint at a corner, comprising the following steps:

[0019] S1: Check the flatness of the aluminum alloy column and fix the fixing parts to the aluminum alloy column with screws;

[0020] S2: Clamp both ends of the accordion plate into the second grooves of the fixing members of the two sets of mounting components;

[0021] S3: inserting the connecting piece into the first groove of the aluminum alloy column;

[0022] S4: Overlap the end of the first folding plate on the connecting piece of the installation assembly and fix it with bolts, then overlap the end of the second folding plate on the connecting piece of another set of installation assembly and fix it with bolts;

[0023] S5: Filling the gap between the first folding plate and the second folding plate with a sealing member;

[0024] S6: Install the decorative cover and V-shaped aluminum plate and rock wool on the indoor side.

[0025] Compared with the prior art, the technical solution of this application has the following advantages and effects:

[0026] 1. In the prior art, the deformation of the deformation joint structure at the corner is limited, which makes it difficult to adapt to various and complex structural deformations, thereby easily leading to deformation of the glass curtain wall frame, cracking of the panel or sealing failure. The present application adopts the setting of L-shaped accordion plates to adapt to the multi-directional displacement deformation of the building at the deformation joint, thereby greatly enhancing the sealing and durability.

[0027] 2. The deformation joint in the prior art is relatively complex in structure and has a great impact on the facade effect. In this application, the first folding plate and the second folding plate are overlapped front and back, and the folding plate of the deformation joint is visible on only one side. Setting this side on the secondary facade can greatly reduce the impact on the facade effect of the glass curtain wall.

[0028] 3. The glass curtain wall structure with deformation joints at corners of the present application is simple in structure, can effectively control engineering costs, is applicable to various building types, and is easy to promote and use.

[0029] 4. The setting of the V-shaped aluminum plate in this application improves the anti-leakage performance of the structure at the deformation joint, and the setting of the decorative cover plate hides the end joints of the first folding plate and the second folding plate, further improving the waterproof performance and enhancing the facade effect.

[0030] 5. The construction method of the glass curtain wall structure with deformation joints at corners of the present application is simple, and the connection parts are mostly snap-fitted, which is easy to construct and operate, and the subsequent maintenance cost is low.
