Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and in particular to a toothed sleeve type curtain wall adapter, which is suitable for connecting and installing decorative components on the outside of curtain walls. Background Technology

[0002] With the continuous development of the construction industry, curtain walls, as an important component of building facades, are showing a trend of "novelty, uniqueness, and distinctiveness," with increasingly complex and diverse appearances. Unique and innovative curtain wall designs have become an industry trend. Among them, decorative components suspended on the outside of the curtain wall, as key elements to enhance its aesthetics, often have varied shapes and different installation angles. This places higher demands on curtain wall transition devices, requiring them to meet the needs of installing decorative components at any angle and facilitating disassembly and maintenance.

[0003] Currently, the installation of exterior decorative components in the curtain wall market mostly adopts the method of using angle brackets and bolts for connection. However, this conventional connection method has many drawbacks: 1. Poor space occupation and exterior decoration effect: The structure of angle bracket and bolt connection occupies a large space, and the angle brackets, bolts and other components are directly exposed, seriously affecting the decorative effect of the exterior of the curtain wall. To cover these exposed components, it is usually necessary to cover or shield the connection area, which not only increases the construction process but also increases the project cost; 2. Limited installation angle and difficulty in adjustment: The installation angle of conventional angle bracket and bolt connection is fixed. Once the installation is completed, it is difficult to adjust the angle of the decorative component. If the angle of the decorative component needs to be changed, angle brackets with appropriate angles must be customized, resulting in a wide variety of adapters and poor versatility; 3. Inconvenient disassembly and maintenance: When decorative components need to be replaced or repaired, the angle bracket and bolt connection method has a certain fixed constraint on adjacent curtain wall components. The disassembly process often requires damage to some adjacent curtain wall structures, which not only has low maintenance efficiency but may also affect the overall structural stability of the curtain wall. Summary of the Invention

[0004] The purpose of this utility model is to provide a toothed sleeve type curtain wall adapter, which solves the problems of single installation angle, poor external decoration, and inconvenient installation and disassembly of the adapter for curtain wall exterior decorative components. Its installation angle is easy to adjust, the exterior decoration effect is good, and disassembly is convenient.

[0005] The technical solution adopted by this utility model is as follows: the toothed sleeve curtain wall adapter includes an adapter body. The key technical points are: the adapter body is a hollow aluminum alloy toothed shaft and an aluminum alloy toothed sleeve assembled together. The outer surface of the aluminum alloy toothed shaft is provided with uniformly distributed tooth-shaped protrusions along the circumferential direction. The inner wall of the aluminum alloy toothed shaft is provided with screw fixing grooves along the extension direction. The inner surface of the aluminum alloy toothed sleeve is provided with tooth-shaped grooves that match and engage with the tooth-shaped protrusions of the aluminum alloy toothed shaft. The outer wall of the aluminum alloy toothed sleeve is provided with screw fixing grooves along the extension direction. The aluminum alloy toothed shaft and the aluminum alloy toothed sleeve are fixed by transverse bolts. The outer ends of the aluminum alloy toothed shaft and the aluminum alloy toothed sleeve are respectively fixed to the base plate by screws and screw fixing grooves.

[0006] The cross-section of the screw fixing groove is C-shaped.

[0007] The number of tooth-shaped protrusions on the aluminum alloy gear shaft is less than the number of tooth-shaped grooves on the aluminum alloy gear sleeve.

[0008] The aluminum alloy gear sleeve and aluminum alloy gear shaft have three sets of screw fixing grooves evenly distributed along the circumference.

[0009] The aluminum alloy gear shaft and aluminum alloy gear sleeve are connected by a transverse through bolt, which is a male and female bolt.

[0010] The outer end face of the aluminum alloy gear sleeve is either a plane or an inclined plane.

[0011] The advantages and beneficial effects of this utility model are as follows: Because this toothed curtain wall adapter uses a set of hollow aluminum alloy toothed shafts and aluminum alloy toothed sleeves, the angle adjustment is flexible, reducing costs. Through the toothed meshing relationship between the aluminum alloy toothed shaft and the toothed sleeve, decorative components can rotate around the axis of the adapter at any angle, eliminating the need to customize multiple adapter parts for different angles, thus reducing processing costs. Simultaneously, it simplifies the installation process, improves curtain wall installation efficiency, and shortens the construction period. It offers excellent exterior finish; the overall cylindrical design of the connection part effectively avoids the use of exposed corner brackets. Disassembly and maintenance are convenient, protecting the structure: During later maintenance or replacement of decorative components, only the top bolts need to be unscrewed to separate the toothed shaft and toothed sleeve, enabling the removal of the decorative component without damaging the adjacent curtain wall structure, greatly improving maintenance efficiency, reducing maintenance costs, and protecting the overall stability of the curtain wall structure. The connection is reliable and stable, with strong adaptability: the toothed meshing structure ensures stable connection of decorative components at any angle, and the bolts further restrict the displacement of components along the axis, providing double protection for connection reliability.

Screw, 7. Bolt, 8. Connecting base plate, 9. Decorative component, 10. Curtain wall frame, 11. Outer end face. Detailed Implementation

[0015] according to Figure 1-7 This utility model will be described in detail, and its implementation will be illustrated by examples. Figure 1 and Figure 2 As shown, a toothed sleeve type curtain wall adapter device has an adapter body consisting of a hollow aluminum alloy toothed shaft 2 and an aluminum alloy toothed sleeve 1, which are assembled together and are cylindrical in shape. Figure 3 As shown, the outer surface of the aluminum alloy gear shaft 2 is provided with uniformly distributed tooth-shaped protrusions 4 along the circumferential direction. In this embodiment, there are 12 tooth-shaped protrusions with trapezoidal teeth. The number can be appropriately increased or decreased according to installation requirements. Screw fixing grooves 3 are provided along the extension direction of the inner wall of the aluminum alloy gear shaft 2 for fixing to the connecting plate with screws. Figure 4 As shown, the inner surface of the aluminum alloy gear sleeve 1 is provided with toothed grooves 5 that match and engage with the toothed protrusions 4 of the aluminum alloy gear shaft. The number of toothed protrusions 4 on the aluminum alloy gear shaft is less than the number of toothed grooves 5 on the aluminum alloy gear sleeve, which facilitates insertion and assembly. The outer wall of the aluminum alloy gear sleeve is provided with screw fixing grooves 3 in the extension direction for fixing to the connecting plate by screws. The screw fixing grooves 3 can be C-shaped in cross-section, which facilitates screw installation and is easy to process. The screw fixing grooves 3 are the same length as the aluminum alloy gear shaft 2 and the aluminum alloy gear sleeve 5, and are integral structural profiles milled from profiles with a certain wall thickness. The screw fixing grooves 3 are commonly referred to as screw lines, which are easy to cut for use. In this embodiment, the screw fixing grooves of the aluminum alloy gear sleeve 1 and the aluminum alloy gear shaft 2 are three sets of screw fixing grooves evenly distributed along the circumference to form a stable structure. Figure 5As shown, the aluminum alloy gear shaft 2 and the aluminum alloy gear sleeve 1 are fixed by transverse bolts 7, which penetrate and fix the meshed aluminum alloy gear shaft and aluminum alloy gear sleeve, restricting the displacement of the components along the axial direction and providing axial positioning. Bolt holes can be pre-drilled in the aluminum alloy gear sleeve, and holes can be drilled on-site to install bolts for fixing. The outer ends of the aluminum alloy gear shaft 2 and the aluminum alloy gear sleeve 1 are respectively fixed to the base plate 8 using screws 6 and screw fixing slots 3. Countersunk screws can be used for screws 6.

[0016] As a further improvement, such as Figure 5 As shown, the aluminum alloy gear shaft 2 and the aluminum alloy gear sleeve 1 are connected by a horizontally penetrating bolt 7 as a male and female bolt. The connection part is designed as a cylinder. After the male and female bolts are tightened, the outer two ends of the bolt are basically flush with the outer ring of the gear sleeve, which effectively avoids the problems of exposed corner brackets and bolts. The surface of the device can be pre-treated in the factory, such as spraying and polishing. After installation, no additional decorative covering or shielding is required, which further reduces the project cost and improves the overall aesthetics of the curtain wall.

[0017] As a further improvement, such as Figure 6 and Figure 7 As shown, the outer end face 11 of the aluminum alloy toothed sleeve 1 is either flat or inclined. The aluminum alloy toothed sleeve 1 is used to connect with the curtain wall frame 10. The outer end face 11 is flat and suitable for connecting the top decorative component 9; the outer end face is inclined and suitable for connecting the bottom decorative component 9. The tilt angle can be set according to the site conditions.

[0018] The installation process is as follows: Assemble the aluminum alloy gear shaft 2 and aluminum alloy gear sleeve 1 together with the connecting base plate 8 using countersunk screws 6. Then, install the aluminum alloy gear shaft 2 assembly onto the decorative component 9 and the aluminum alloy gear sleeve 1 assembly onto the curtain wall frame 10. After placing the decorative component in the required position, use bolts 7 to penetrate and tighten the aluminum alloy gear shaft and aluminum alloy gear sleeve of the top adapter of the decorative component to fix the decorative component between the curtain walls. The bottom adapter does not need to be fixed by bolts to meet the expansion and contraction requirements between the curtain walls. When disassembly is required, simply reverse the above steps.

[0019] Working principle This utility model's toothed sleeve curtain wall adapter achieves arbitrary angle installation and convenient disassembly of decorative components through the dual functions of toothed engagement for angle adjustment and bolt fixing. The outer surface of the aluminum alloy toothed shaft and the inner surface of the aluminum alloy toothed sleeve are provided with matching trapezoidal tooth structures. Due to the continuous engagement of the toothed shaft and the toothed sleeve, arbitrary angle positioning within a 360° range can be achieved during rotation until the preset installation angle is reached, preventing angular displacement of the decorative components during subsequent fixing. After the angle of the decorative component is adjusted to the correct position, the male and female bolts penetrate the axial holes of the aluminum alloy toothed shaft and the aluminum alloy toothed sleeve. After tightening the male and female bolts, the bolt heads and nuts respectively generate axial pressure on the toothed shaft and the toothed sleeve, making the toothed structures of the toothed shaft and the toothed sleeve tightly engaged, further fixing the angle of the decorative component. At the same time, the male and female bolts restrict the displacement of the decorative component along the axial direction, preventing axial loosening of the decorative component due to external forces such as vibration and wind during use, ensuring the reliability of the connection. After the bolts are tightened, the outer ends of the bolts are basically flush with the outer ring of the toothed sleeve, having minimal impact on the exterior finish and requiring no additional treatment. The adapter at the bottom of the decorative component achieves initial positioning only through the engagement of the toothed shaft and the toothed sleeve, without using bolts for penetration fixation. When the curtain wall expands or contracts due to temperature changes (such as expansion in summer and contraction in winter), the bottom toothed shaft and the toothed sleeve can slide slightly along the axis to compensate for the expansion and contraction of the curtain wall, preventing additional stress on the device due to the expansion and contraction of the curtain wall, thereby protecting the structural integrity of the curtain wall and the adapter and extending its service life.

[0020] In summary, the purpose of this utility model has been achieved.
