Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a quick-installation glass curtain wall connection system. Background Technology

[0002] A curtain wall is the exterior wall cladding of a building, composed of curtain wall units, a structural support keel system, and hanging connection devices. The vertical connection system of a glass curtain wall plays a crucial role in the installation process, supporting not only the weight of the curtain wall but also ensuring its stability and safety. However, traditional curtain wall connection systems have complex components and numerous connecting parts. Some require the addition of multiple horizontal beams between the vertical keels, necessitating the addition of grid connectors between the hanging devices and the curtain wall panels, or the use of multiple screws for fixing the curtain wall panels to the slots, keels, and slots. This makes the installation of curtain wall unit panels cumbersome and the construction time long when the curtain wall is installed in the air. At the same time, the removal process for regular maintenance or replacement of damaged panels during use is also cumbersome. Furthermore, the installation, maintenance, and replacement of curtain walls can easily damage adjacent panels, resulting in collateral maintenance issues. Traditional curtain wall connection systems require customized matching brackets for different curtain wall units, increasing inventory management costs. Furthermore, in some curtain wall connection systems, the space between the brackets and the side slots of the curtain wall is too large, causing the curtain wall unit panels to easily detach and fall out of the brackets. When the space is too large, longer bracket bolts are needed to fix the curtain wall panels, or double-layer brackets are needed for fixation, or structural adhesive is needed to fully fix them in a large space. In other curtain wall connection systems, the space between the brackets and the side slots of the curtain wall is too small, which can easily lead to problems such as curtain wall deformation and cracking due to structural settlement. Utility Model Content

[0003] The purpose of this utility model is to provide a quick-installation glass curtain wall connection system with a simple structure, few accessories, convenient installation and disassembly, and high stability. It can not only ensure the safety of construction during the installation and disassembly of curtain wall hangers, but also make construction simpler and faster, greatly shortening the construction cycle. Through quick installation and disassembly, it is easier to realize the layered installation of the curtain wall, regular maintenance, and quick replacement of damaged panels.

[0004] The technical solution of this utility model is a quick-installation glass curtain wall connection system, including:

[0005] The structural support keel system includes aluminum alloy columns, which extend outward from opposite side walls to form keel slots. The keel slots are arranged vertically, and a first groove is provided in the keel slot. The opening of the first groove is opposite to the gap reserved between two adjacent curtain wall units on the left and right.

[0006] A curtain wall unit includes a sub-frame installed in the keel slot, the sub-frame having a curtain wall slot, and the openings of the curtain wall slots of two adjacent curtain wall units facing each other;

[0007] The mounting connection device includes a mounting plate and a bolt. The mounting plate is installed in the keel slot and its end extends into the curtain wall slot. The head of the bolt is installed in the first groove, and its shank extends along the gap and passes through the mounting plate before being threaded into a nut. Tightening the nut fixes the curtain wall unit to the structural support keel system.

[0008] Preferably, the mounting plate is an E-shaped aluminum alloy plate, including a support portion abutting against both sides of the opening of the first groove and a horizontal portion perpendicular to the support portion. A bolt hole is provided in the middle of the horizontal portion, and both ends of the horizontal portion extend into the adjacent curtain wall slots and have protrusions extending downward at both ends. When the lower surface of the horizontal portion is in contact with the inner wall of the curtain wall slot, the protrusions are engaged in the second groove opened on the inner wall of the curtain wall slot.

[0009] Preferably, the width of the second groove is greater than the width of the protrusion, so that the protrusion can move left and right within the second groove, thereby driving the hanging plate to move left and right relative to the curtain wall slot.

[0010] Preferably, the width of the curtain wall slot is greater than the thickness of the horizontal part of the mounting plate, so that the mounting plate can move back and forth relative to the curtain wall slot.

[0011] Preferably, the width of the opening of the first groove is smaller than the diameter of the bolt head and greater than or equal to the diameter of the bolt shank.

[0012] Preferably, the hanging connection devices are arranged at intervals along the vertical direction, and the distance between two adjacent hanging connection devices is 1.2m.

[0013] Preferably, a rubber pad is installed between the sub-frame and the aluminum alloy column, and the rubber pad is located at the stress point of the hanging plate.

[0014] Preferably, a third groove is provided on the side wall of the sub-frame near the aluminum alloy column, and one side of the rubber pad is inserted into the third groove, while the other side of the rubber pad abuts against the aluminum alloy column.

[0015] Preferably, the curtain wall unit further includes curtain wall glass and an aluminum alloy frame. The curtain wall glass and the aluminum alloy frame are assembled to form a single-pane glass curtain wall. The sub-frame is fixed to the connection part of the aluminum alloy frame by structural adhesive and double-sided adhesive.

[0016] Preferably, the structural support keel system also includes galvanized steel columns, which are installed inside the aluminum alloy columns and are fastened to the aluminum alloy columns by stainless steel screws.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] (1) By reducing the number of accessories in the curtain wall connection system, the installation and dismantling process between the curtain wall unit and the structural support keel system is made simpler and faster, which improves construction efficiency and reduces material costs. When performing regular maintenance or replacing damaged panels, the damaged parts can be replaced quickly without large-scale disassembly. At the same time, by optimizing the accessory structure and connection method in the curtain wall connection system, the stability of the curtain wall connection system is improved.

[0019] (2) By installing the sub-frame of the curtain wall unit in the keel slot, and utilizing the protruding baffles on both sides of the keel slot, as well as the cooperation between the protrusions on the lower surface of the hanging plate and the second groove set on the inner wall of the curtain wall slot, the curtain wall unit is not easy to slip out of the hanging device and fall off.

[0020] (3) By optimizing the hanging component connection device, a small single-layer hanging panel hanging component connection device made of high-strength aluminum alloy is adopted. Workers only need to tighten the nuts to fasten the curtain wall unit to the structural support keel system, and there is no need to add self-tapping screws or structural adhesive to fix the hanging components. The installation efficiency is high, the overall material cost is low, and the stability is good after installation. At the same time, by adopting a universal interface standardization to be compatible with curtain wall panels of different thicknesses and materials, the universality and adaptability of the hanging component connection device are improved, and the warehouse management cost is reduced accordingly.

[0021] (4) By optimizing the spatial spacing between the mounting plate and the curtain wall slot, the mounting plate can be adjusted within a certain range to adapt to the positional changes caused by structural settlement. This avoids problems such as curtain wall deformation and cracking caused by structural settlement due to insufficient space between the mounting plate and the curtain wall slot; and also avoids problems such as curtain wall units easily falling off and scratching the hangers due to excessive space between the mounting plate and the curtain wall slot, as well as the need for longer hanger bolts, double-layer mounting plates, or additional structural adhesive for complete fixation when the space is too large.

[0022] (5) By combining galvanized steel columns and aluminum alloy columns to form a structural support keel system, the overall strength of the glass curtain wall connection system is increased. There is no need to add crossbeams between the columns. The keel columns themselves are strong, which in turn increases the overall strength of the glass curtain wall connection system.

[0023] (6) By using rubber pads to set flexible nodes at the points of strongest stress on both sides of the mounting plate, the rubber pads are located between the sub-frame of the curtain wall unit and the aluminum alloy columns of the structural support keel system. This can buffer the impact of structural settlement on the curtain wall and reduce stress concentration when the main structure has slight displacement and deformation. Attached Figure Description

[0033] This utility model will be further described in detail below with reference to the accompanying drawings:

[0034] Please see Figures 1 to 4 As shown, this utility model provides a quick-installation glass curtain wall connection system, including: a structural support keel system 1 and a curtain wall unit 2, wherein the curtain wall unit 2 is fixed to the structural support keel system 1 by a hanging connection device 3. Please refer to [link / reference]. Figure 1As shown, the structural support keel system 1 includes aluminum alloy columns 11. The aluminum alloy columns 11 extend outward from opposite side walls to form keel slots 111. The keel slots 111 are arranged vertically. The keel slots 111 have a first groove 112. The opening of the first groove 112 is opposite to the gap 21 reserved between two adjacent curtain wall units 2. The curtain wall unit 2 includes a sub-frame 22 installed in the keel slots 111. The sub-frame 22 has a curtain wall slot 221. The openings of the curtain wall slots 221 of two adjacent curtain wall units 2 are opposite to each other. The hanging connection device 3 includes a hanging plate 31 and a bolt 32. The hanging plate 31 is installed in the keel slots 111 and its end extends into the curtain wall slot 221. The bolt head 321 is installed in the first groove 112. The bolt shank 322 extends along the gap 21 and passes through the hanging plate 31 before being threadedly connected to the nut 33. Tightening the nut 33 fixes the curtain wall unit 2 to the structural support keel system 1. The quick-installation glass curtain wall connection system provided by this utility model optimizes the form and quantity of accessories in the curtain wall connection system, reducing the number of accessories. It eliminates the need for additional accessories such as horizontal beams, grid connectors, and bolts between vertical keels, making installation and disassembly simpler and faster, and significantly shortening the construction cycle. By optimizing the hanging structure and using small, single-layer hanging panel hanging connection devices, each hanging connection device requires only a single bolt. In this embodiment, only 30mm long φ5mm stainless steel bolts are used, eliminating the need for additional self-tapping screws, resulting in lower overall material costs and better stability after installation. Furthermore, the glass curtain wall connection system eliminates the need for structural adhesive connections, making it easier to achieve layered installation of the curtain wall and regular maintenance, replacement of damaged panels, etc. Damaged parts can be quickly replaced without large-scale disassembly, improving construction flexibility.

[0035] Please see Figure 2 As shown, the mounting plate 31 is an E-shaped aluminum alloy plate. In this embodiment, the mounting plate is made of high-strength aluminum alloy material. After removing surface impurities, the aluminum alloy material is precisely cut, bent, punched, and processed using a CNC machine tool according to the design drawings. After processing, the aluminum alloy plate undergoes surface anodizing treatment.

[0036] It should be noted that the E-shaped aluminum alloy panel includes full E-shaped and half E-shaped aluminum alloy panels. The full E-shaped aluminum alloy panel is used for the hanging connection device between the curtain wall units in the middle, and the half E-shaped aluminum alloy panel is used for the hanging connection device between the curtain wall units on the edge and the structural support keel system.

[0037] Please see Figure 2 As shown, the mounting plate 31 includes support portions 311 abutting against both sides of the opening of the first groove 112 and a horizontal portion 312 perpendicular to the support portions 311. A bolt hole is provided in the center of the horizontal portion 312 for a bolt 32 to pass through. In this embodiment, a φ5mm bolt hole is provided in the center of the E-shaped aluminum alloy plate; as shown... Figure 2 As shown, both ends of the horizontal portion 312 extend into the adjacent curtain wall slots 221, and each end has a downward-extending protrusion 3121. When the lower surface of the horizontal portion 312 is in contact with the inner wall of the curtain wall slot 221, the protrusion 3121 engages with the second groove 222 opened on the inner wall of the curtain wall slot 221. By engaging the protrusion 3121 into the second groove 222, the connection between the mounting plate 31 and the sub-frame 22 can be strengthened, ensuring that the hanger is not easy to fall off; and through the cooperation of the protrusion 3121 and the second groove 222, the risk of the curtain wall unit 2 sliding off the mounting plate 31 and falling off can be further reduced, ensuring the safety and stability of the curtain wall.

[0038] like Figure 2 As shown, the width of the second groove 222 is greater than the width of the protrusion 3121, allowing the protrusion 3121 to move left and right within the second groove 222, thereby causing the mounting plate 31 to move left and right relative to the curtain wall slot 221. By finely adjusting the position of the mounting plate 31 left and right, the mounting bracket connection device 3 can be installed in place, thereby better securing the curtain wall unit 2 to the structural support keel system 1.

[0039] like Figure 2 As shown, the width h1 of the curtain wall slot 221 is greater than the thickness h2 of the horizontal part 312 of the mounting plate 31, thereby allowing the mounting plate 31 to move back and forth relative to the curtain wall slot 221. By optimizing the spatial distance between the mounting plate 31 and the curtain wall slot 221, the mounting plate 31 can be adjusted within a certain range to adapt to positional changes caused by structural settlement. This avoids problems such as curtain wall deformation and cracking caused by insufficient space between the mounting plate and the curtain wall slot, which can lead to the curtain wall unit easily falling off and sliding out of the hanging connection device, and also avoids problems such as the need for longer hanging bolts, double-layer hanging plates, or additional structural adhesive for complete fixation when the space is too large.

[0040] like Figure 2 As shown, the width of the opening of the first groove 112 is less than the diameter of the bolt head 321 and greater than or equal to the diameter of the bolt shank 322, in order to restrict the movement of the bolt head 321 and prevent the bolt head 321 from coming out of the first groove 112. At the same time, the bolt head 321 is limited by the first groove 112 and will not cause the bolt shank 322 to rotate freely.

[0041] Please see Figures 3 to 4 As shown, the hanging connection devices 3 are arranged at intervals along the vertical direction; in this embodiment, the distance d between two adjacent hanging connection devices 3 is 1.2m.

[0042] Please see Figures 1 to 2As shown, a rubber pad 4 is installed between the sub-frame 22 and the aluminum alloy column 11. The rubber pad 4 is located at the stress point of the hanging plate 31. By installing the rubber pad 4 at the point where the stress is strongest on both sides of the hanging plate 31, a flexible node is set up. When there is a slight displacement and deformation between the curtain wall and the main structure, the impact of structural settlement on the curtain wall is buffered, and stress concentration is reduced.

[0043] In this embodiment, as Figure 2 As shown, a third groove 223 is provided on the side wall of the sub-frame 22 near the aluminum alloy column 11. One side of the rubber pad 4 is inserted into the third groove 223, and the other side of the rubber pad 4 is pressed against the aluminum alloy column 11, thereby reducing the risk of displacement of the rubber pad 4.

[0044] Please see Figure 1 As shown, the curtain wall unit 2 also includes curtain wall glass and aluminum alloy frame. The curtain wall glass and aluminum alloy frame are assembled to form a single glass curtain wall 23. The sub-frame 22 is fixed to the connection part of the single glass curtain wall 23 by structural adhesive 24 and double-sided adhesive.

[0045] In this embodiment, based on the design drawings, the specific parameters such as the size, shape, and connection method of the curtain wall are determined. High-strength aluminum alloy material is selected and cut into aluminum alloy frames. The cut aluminum alloy frames are then bent using a bending machine or tube bending machine. By adjusting the mold and bending parameters, the aluminum alloy profiles are bent into the required arc or angle. The connection parts at the curtain wall unit frames are manufactured using a stamping process. Using a punch press and corresponding molds, mounting holes, slots, tenons, and other structures are stamped into the aluminum alloy frames to ensure dimensional accuracy and positional precision. The aluminum alloy frames are then milled. After processing, the aluminum alloy components undergo surface anodizing treatment. Finally, the curtain wall glass and aluminum alloy frames are assembled into individual unit panels, thus forming a single-pane glass curtain wall 23.

[0046] It is worth noting that the glass curtain wall connection system can adapt to curtain wall panels of different sizes and specifications. The sub-frame 22 can be connected to single glass curtain walls 23 of different sizes using structural adhesive. The curtain wall slot 221 has a large space and does not require any other extra connectors, making the hanging connection device 3 highly versatile, environmentally friendly, and economically efficient.

[0047] Please see Figure 1 As shown, the structural support keel system 1 also includes galvanized steel columns 12, which are installed inside the aluminum alloy columns 11. The galvanized steel columns 12 are fastened to the aluminum alloy columns 11 by stainless steel screws 13. By combining the galvanized steel columns 12 with the aluminum alloy columns 11, the overall strength of the glass curtain wall connection system is improved. No additional crossbeams are needed between the columns, and the structural support keel system 1 itself has high strength, thus increasing the overall strength of the glass curtain wall connection system.

[0048] In this embodiment, based on the design drawings, specific parameters such as size, shape, and connection method are determined. High-strength aluminum alloy material is selected and cut into aluminum alloy columns 11. The cut aluminum alloy columns 11 are then bent. The aluminum alloy profile is bent into the required arc or angle, and the connection parts of the aluminum alloy columns 11 are made using a stamping process. Using a punch press and corresponding molds, mounting holes, slots, tenons, and other structures are stamped into the aluminum alloy columns 11, and then the aluminum alloy columns 11 are milled. After processing, the aluminum alloy parts are anodized. According to the design length, galvanized steel columns 12 are cut to the appropriate size using cutting equipment. Then, according to the position and spacing of the mounting holes on the aluminum alloy columns 11, holes are drilled in the galvanized steel columns 12, ensuring that the positional accuracy and hole diameter of the holes meet the requirements so as to reliably connect with the aluminum alloy columns 11 using bolts or other connecting parts. Cut a galvanized steel column 12 to the designed length, insert the galvanized steel column 12 into the aluminum alloy column 11, and use stainless steel screws 13 to fasten the galvanized steel column 12 to the aluminum alloy column 11 through the pre-processed mounting holes.

[0049] The installation of the components of this utility model quick-installation glass curtain wall connection system includes: after the structural support keel system 1 is installed on the structure, the sub-frame 22 of the curtain wall unit 2 is inserted into the keel slot 111; after the single curtain wall unit 2 is placed in place, the hanging connection device 3 is vertically slid into the keel slot 111 and the curtain wall slot 221, wherein the hanging plate 31 is placed in the keel slot 111 and the end extends into the curtain wall slot 221, the bolt head 321 is placed in the first groove 112 and the bolt shank 322 passes through the hanging plate 31 and is threaded to the nut 33, and the hanging connection device 3 is set at every 1.2m interval; after the hanging connection device 3 is slid into place, the nut 33 is tightened to complete the installation.
