Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy profile technology, specifically to an aluminum alloy profile for glass curtain walls. Background Technology

[0002] A glass curtain wall refers to an exterior building envelope or decorative structure that is supported by a structural system and allows for a certain degree of displacement relative to the main structure, without sharing the loads of the main structure. The wall can be single-layered or double-layered with glass. Glass curtain walls are an aesthetically pleasing and innovative method of architectural wall decoration, a prominent feature of the modernist high-rise building era.

[0003] Existing patent document CN216948952U discloses a frame curtain wall installation system with a closed-cavity horizontal beam. The protected claim includes "decorative covers, external pressure plates, curtain wall glass, curtain wall mullions, curtain wall horizontal beams, horizontal beam connecting brackets, horizontal beam buckles, glass supports, aluminum alloy pressure blocks, and an aluminum alloy sub-frame. The curtain wall mullions are connected and fixed to the horizontal beams by connecting brackets, and the curtain wall horizontal beams are fixed to each other by connecting brackets. The curtain wall glass is locked in place by the external pressure plate, and the curtain wall glass is fixed to the curtain wall mullions and external pressure plate by sealing strips, forming a curtain wall system. The curtain wall glass is bonded to the glass sub-frame by structural adhesive and double-sided adhesive strips. The bonded panels are fixed to the curtain wall horizontal beams by aluminum alloy pressure blocks. The curtain wall glass is supported by glass supports, forming a complete curtain wall system. The curtain wall installation system proposed in this utility model has a high utilization rate of the mechanical properties of the closed profiles, and the use of closed horizontal beams improves material utilization and reduces curtain wall costs."

[0004] However, the frame curtain wall installation system with closed-cavity beams in the aforementioned publicly available literature mainly considers the high utilization rate of the mechanical properties of the closed profiles. The use of closed beams improves the utilization rate of materials and reduces the cost of the curtain wall. However, it does not take into account the fact that the curtain wall mullions and external pressure plates can only clamp and fix the curtain wall glass within a specific width range. If the project needs to use glass of a non-specific width, it may be necessary to customize special curtain wall mullions and external pressure plates, which will significantly increase material and processing costs, and may in turn affect the applicability of aluminum alloy profiles.

[0005] The purpose of this utility model is to provide an aluminum alloy profile for glass curtain walls to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An aluminum alloy profile for glass curtain walls includes a column and a pressure plate. The column is provided with a connector that can be moved in a limited position and can cooperate with the pressure plate. The connector is provided with a threaded hole. The connector and the pressure plate are connected by a locking bolt that cooperates with the threaded hole on the connector. The column and the connector are also provided with a positioning structure, which includes a positioning hole one, a positioning hole two, and a positioning bolt.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the limiting movement between the connector and the column and the design of multiple sets of positioning holes, can adjust the position within a certain range to adapt to glass curtain walls of different widths, solving the limitation of traditional fixed grooves that cannot be adjusted, and improving the versatility and applicability of the profile; the limiting installation groove of the groove on the frame body cooperates with the guide installation part of the connector to realize the precise limiting movement of the connector, ensuring installation accuracy and avoiding skewing or offset during installation. At the same time, the setting of positioning bolts further ensures the stability of the connector after it is fixed, preventing loosening and displacement during use; the frame body, as an extension of the column, increases the moment of inertia of the profile section, significantly improving the bending and torsional strength of the column, which can meet the load requirements of large-span curtain walls and ensure the safety of the curtain wall under complex stress conditions.

[0020] Please see Figure 1-3An aluminum alloy profile for glass curtain walls includes a column 1 and a pressure plate 3. The column 1 is equipped with a movable connector 2 that mates with the pressure plate 3. The connector 2 has threaded holes. The connector 2 and the pressure plate 3 are connected by locking bolts 5 that mate with the threaded holes on the connector 2. The column 1 and the connector 2 are also equipped with positioning structures, including a first positioning hole 11, a second positioning hole 12, and a positioning bolt 13. Both the column 1 and the pressure plate 3 are fitted with clamping devices for securing the glass curtain wall. The pressure plate 3 is detachably equipped with a decorative cover 4 that can be used with the fixed adhesive strip 6. The column 1 is the main frame of the curtain wall profile, bearing the weight of the glass panel, wind load, seismic action and other external forces to ensure the overall stability of the curtain wall. The connector 2 is the connection hub between the column 1 and the pressure plate 3. It can achieve relative sliding with the column 1 through the limit movement setting. With the positioning structure (positioning hole, positioning bolt 13), the position can be adjusted within a certain range to adapt to glass curtain walls of different widths. The pressure plate 3 is used for glass clamping and fixing. The core is fixed and works with the column 1. The adhesive strip 6 applies clamping force to the glass edge to fix the glass position and prevent displacement or detachment. The locking bolt 5 is the fastening component of the connector 2 and the pressure plate 3. It passes through the threaded hole of the connector 2 and connects to the pressure plate 3. The clamping force generated by tightening the bolts fixes the pressure plate 3 to the connector 2, ensuring that the glass is firmly clamped. The adhesive strip 6 fills the gap between the column 1 and the glass, and between the pressure plate 3 and the glass, to prevent rainwater and dust from entering and to meet the sealing performance requirements of the curtain wall. It absorbs the deformation stress of the glass caused by temperature changes and wind loads, and avoids the glass edge from directly hitting the metal profile, preventing cracking. The elastic adhesive strip 6 can also fill the small gaps between the glass and the profile to ensure that the clamping force is evenly distributed and improve the reliability of the fixation. The decorative cover 4 can be detachably installed on the outside of the pressure plate 3 to cover the exposed parts such as bolts and connector 2, so that the surface of the curtain wall is flat and uniform, which meets the requirements of architectural aesthetics. It can also isolate the external environment (such as ultraviolet rays and rainwater) from the corrosion of the bolts of the pressure plate 3, extend the service life of metal components, and reduce maintenance costs.

[0021] Please see Figure 2 and Figure 3The column 1 is equipped with a frame 7, which has grooves 8 that mate with connectors 2. Multiple sets of limiting mounting grooves 9 are provided in the grooves 8 of the frame 7. Multiple sets of guide mounting parts 10 are provided on the connectors 2 that mate with the limiting mounting grooves 9. Multiple sets of positioning holes 11 are provided in the grooves 8 of the frame 7, and multiple sets of positioning holes 12 are provided on the connectors 2 that mate with the positioning holes 11. Positioning bolts 13 can pass through the corresponding positioning holes 11 and 12. The frame 7, as an extension of the column 1, increases the moment of inertia of the profile section, improves the bending and torsional strength of the column 1, and meets the load requirements of the large-span curtain wall. The groove 8 provides installation space for the connector 2. The limiting installation groove 9 inside it cooperates with the guide installation part 10 of the connector 2 to realize the limiting movement of the connector 2 and ensure installation accuracy. The guide installation part 10 is embedded in the limiting installation groove 9 to restrict the movement direction of the connector 2 and avoid skewing or offset during installation. At the same time, it provides a reference for the setting of positioning holes. The positioning bolt 13 passes through the positioning hole 11 and the positioning hole 12 to fix the connector 2 in the designated position of the column 1 and prevent loosening and displacement during use. Multiple sets of positioning holes allow the connector 2 to be adjusted laterally on the column 1 to adapt to the clamping requirements of glass of different widths and solve the limitations of traditional fixed grooves.

[0022] Working principle: Column 1 serves as the main frame, with the frame body 7 enhancing structural strength. It withstands external forces such as the self-weight of the glass panel, wind load, and seismic action, maintaining the overall stability of the curtain wall. Connector 2 relies on the cooperation of the limiting installation groove 9 in the groove 8 on the frame body 7 and its own guide installation part 10 to achieve limited movement along the column 1. Before the positioning bolt 13 passes through the positioning hole 11 and positioning hole 12, its position can be adjusted within a certain range according to the width of the glass curtain wall. After determining the position, tighten the positioning bolt 13 to fix connector 2 to the column 1. Subsequently, pressure plate 3 is connected to connector 2 through locking bolt 5. The locking bolt 5 passes through the threaded hole of connector 2, and after tightening, it generates clamping force on pressure plate 3, making pressure plate 3 cooperate with column 1. Pressure is applied to the glass edge through adhesive strip 6 to firmly clamp and fix the glass. Adhesive strip 6, with its own elasticity, fills the gap between column 1, pressure plate 3, and glass, effectively preventing rainwater and dust from entering and achieving curtain wall sealing. It can also absorb the glass caused by environmental factors. The deformation stress generated by the material prevents damage to the glass edges. The decorative cover 4 is installed on the outside of the pressure plate 3 to cover exposed components, which not only meets the requirements of architectural aesthetics, but also protects the pressure plate 3 and bolts from external environmental corrosion. Through the limiting movement between the connector 2 and the column 1 and the design of multiple sets of positioning holes, the position can be adjusted within a certain range to adapt to glass curtain walls of different widths. This solves the limitation of traditional fixed grooves that cannot be adjusted, and improves the versatility and applicability of the profile. The limiting installation groove 9 of the groove 8 on the frame 7 cooperates with the guide installation part 10 of the connector 2 to realize the precise limiting movement of the connector 2, ensure installation accuracy, and avoid skewing or offset during installation. At the same time, the setting of the positioning bolt 13 further ensures the stability of the connector 2 after it is fixed and prevents loosening and displacement during use. As an extension of the column 1, the frame 7 increases the moment of inertia of the profile section, which significantly improves the bending and torsional strength of the column 1, can meet the load requirements of large-span curtain walls, and ensure the safety of the curtain wall under complex stress conditions.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
