Abstract
Description
Technical Field
[0001] This invention relates to the field of glass curtain wall installation technology, and more specifically, to a connecting component for connecting glass curtain wall keel. Background Technology
[0002] Vertical studs are the main load-bearing members of the curtain wall system, typically installed along the entire length of the building or in sections. Horizontal studs are secondary load-bearing members, installed horizontally between two vertical studs. Each "frame" formed by the intersection of horizontal and vertical studs is an independent glass panel installation unit, facilitating design, production, and on-site installation. Horizontal and vertical studs, together with glass, sealant, operable windows, and other components, constitute a complete building envelope system.
[0003] In existing framed glass curtain wall systems, the horizontal and vertical keel connections generally adopt a full spring pin connection method. This connection method requires high precision in keel drilling and positioning. If the precision is insufficient, it may lead to loosening or failure of the keel connection, increasing the construction difficulty and rework risk. Especially in high-rise wind pressure areas or earthquake-prone areas, the stability of the spring pins may be insufficient, leading to keel instability and causing safety hazards. Summary of the Invention
[0004] In view of this, the present invention proposes a connection component for connecting glass curtain wall keels to solve the problems existing in the prior art.
[0005] To achieve the above objectives, the present invention proposes a connecting assembly for connecting glass curtain wall keel, comprising an aluminum alloy column, at least one aluminum alloy beam, an aluminum alloy connector, a spring pin, and screws. The aluminum alloy column includes at least two opposing first upright plates, each of which has a pin hole. The aluminum alloy crossbeam is internally fixed with a spring pin mounting structure. The spring pin mounting structure and the pin hole are at the same horizontal height. One end of the spring pin is installed in the spring pin mounting structure, and the other end of the spring pin is installed in the pin hole. The front side of the aluminum alloy column has a first mounting portion, which extends along the height direction of the aluminum alloy column. The front side of the aluminum alloy beam has a slot structure that extends along the length of the aluminum alloy beam. The aluminum alloy connector includes an integrally formed or fixedly connected snap-fit part and an insert part. The snap-fit part is used to engage with the first mounting part, and the insert part is used to be embedded into the slot structure. The screw is used to fasten the snap-fit portion and the first mounting portion.
[0006] In one embodiment, the first mounting portion includes a portion of vertical structure located at the edge of the first upright plate, a second upright plate, and a third upright plate; The second upright plate is perpendicular to the first upright plate and located inside the first upright plate. The second upright plate is integrally formed or fixedly connected to the first upright plate. The third upright plate is perpendicular to the second upright plate and located outside the second upright plate. The third upright plate is integrally formed or fixedly connected to the second upright plate, and the outer edge of the third upright plate is flush with the outer edge of the first upright plate.
[0007] In one embodiment, the first, second, and third uprights form a groove-shaped structure, and the outer vertical edges of the first and third uprights are bent toward the inside of the groove-shaped structure.
[0008] In one embodiment, the spring pin mounting structure includes a mounting tube and a baffle. The mounting tube is fixedly disposed inside the aluminum alloy beam, and the mounting tube extends along the length direction of the aluminum alloy beam. The baffle is fixedly installed inside the mounting tube.
[0009] In one embodiment, the sidewall of the mounting tube has a notch that extends along the length of the mounting tube.
[0010] In one embodiment, the inner side of the aluminum alloy beam has a second connecting plate and a fourth upright plate; the second connecting plate and the fourth upright plate are parallel to each other and both are perpendicular to the side wall of the aluminum alloy beam, the vertical dimension of the fourth upright plate is smaller than the vertical dimension of the fourth upright plate, and the second connecting plate, the fourth upright plate and the side wall of the aluminum alloy beam form the slot structure.
[0011] In one embodiment, the cross-section of the snap-fit portion is a C-shaped structure or a U-shaped structure.
[0012] In one embodiment, the embedding part is a flat plate structure, and the portion of the embedding part that contacts the slot structure has a boss.
[0013] In one embodiment, the aluminum alloy column has two symmetrically arranged right-angle connecting parts, which are connected by a first connecting plate.
[0014] In one embodiment, the spring pin includes a pin and a spring, the spring being sleeved on the pin and one end of the spring being engaged with a step on the pin.
[0015] Compared with the prior art, the beneficial effect of the present invention is that even if there is a slight deviation between the spring pin and the pin hole on the first upright plate, the strength and stability of the connection body can still be reliably guaranteed by the snap-fit part of the aluminum alloy connector engaging the first mounting part of the upright and fastening it with screws. This significantly reduces the requirements for drilling and positioning accuracy during keel processing and on-site installation, simplifies the construction process, and reduces the risk of rework due to insufficient accuracy.
[0016] Under wind pressure or seismic loads, traditional single spring pin connections may loosen due to vibration or excessive force. This solution creates multiple force transmission paths through the combined action of spring pins and mechanical locking. The spring pins bear the initial positioning and part of the shear load, while the main tensile, compressive, and bending moment loads are transmitted through the rigid connection formed between the tightened snap-fit part and the first mounting part. This combination of rigidity and flexibility, especially the direct mechanical locking force provided by the screws, effectively prevents instability and loosening at the connection under complex stress conditions, significantly improving the safety and reliability of the curtain wall system under harsh operating conditions.

[0019] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0020] This embodiment proposes a connection component for connecting glass curtain wall keels, referencing... Figures 1 to 4 The connecting assembly includes an aluminum alloy column 1, at least one aluminum alloy beam 2, an aluminum alloy connector 3, a spring pin, and a screw 5.
[0021] The aluminum alloy column 1 includes at least two opposing first upright plates 11, each having a pin hole.
[0022] The aluminum alloy crossbeam 2 is internally fixed with a spring pin mounting structure. The spring pin mounting structure and the pin hole are at the same horizontal height. One end of the spring pin is installed in the spring pin mounting structure, and the other end of the spring pin is installed in the pin hole.
[0023] The front side of the aluminum alloy column 1 has a first mounting part 15, which extends along the height direction of the aluminum alloy column 1; the front side of the aluminum alloy beam 2 has a slot structure, which extends along the length direction of the aluminum alloy beam 2.
[0024] Reference Figure 7 The aluminum alloy connector 3 includes an integrally formed or fixedly connected snap-fit part 31 and an insert part 32. The snap-fit part 31 is used to engage the first mounting part 15, and the insert part 32 is used to be embedded into the slot structure. The screw 5 is used to fasten the snap-fit part 31 and the first mounting part 15. The aluminum alloy connector 3 adopts an integrated snap-fit part 31 and insert part 32 design. During installation, the insert part 32 can be pre-positioned by first inserting it into the slot structure on the front side of the crossbeam 2, then the snap-fit part 31 can be aligned and engaged with the first mounting part 15 of the column 1, and finally fastened with the screw 5.
[0025] In the above embodiments, traditional connections rely entirely on the precise alignment of the spring pin and the pin hole. In this solution, even if there is a slight deviation between the spring pin and the pin hole on the first upright plate 11, the main strength and stability of the connection can still be reliably guaranteed by the snap-fit portion 31 of the aluminum alloy connector 3 engaging with the first mounting portion 15 of the column 1 and being secured with screws 5. This significantly reduces the requirements for drilling and positioning accuracy during keel processing and on-site installation, simplifies the construction process, and reduces the risk of rework due to insufficient accuracy.
[0026] Under wind pressure or seismic loads, traditional single spring pin connections may become loose due to vibration or excessive force. This solution creates multiple force transmission paths through the combined action of spring pins and mechanical locking. The spring pins bear the initial positioning and part of the shear load, while the main tensile, compressive, and bending moment loads are transmitted through the rigid connection formed by the fastened snap-fit part 31 and the first mounting part 15. This combination of rigidity and flexibility, especially the direct mechanical locking force provided by the screws 5, effectively prevents instability and loosening at the connection under complex stress conditions, significantly improving the safety and reliability of the curtain wall system under harsh working conditions.
[0027] In some embodiments, the first mounting portion 15 includes a partial vertical structure located at the edge of the first upright plate 11, a second upright plate 16, and a third upright plate 17; the second upright plate 16 is perpendicular to the first upright plate 11 and located inside the first upright plate 11, and the second upright plate 16 is integrally formed or fixedly connected to the first upright plate 11; the third upright plate 17 is perpendicular to the second upright plate 16 and located outside the second upright plate 16, and the third upright plate 17 is integrally formed or fixedly connected to the second upright plate 16, with the outer edge of the third upright plate 17 flush with the outer edge of the first upright plate 11, forming a regular mounting reference surface. This multi-faceted contact not only increases the effective contact and friction area, but also makes the tightening force of the screw 5 more evenly distributed.
[0028] In the above embodiment, the first mounting part 15, together with the first upright plate 11, the second upright plate 16 which is vertically inward, and the third upright plate 17 which is vertically outward again, forms a three-dimensional reinforced structure similar to a "C". When the snap-fit part 31 embraces this structure and is fastened by the screw 5, the second upright plate 16 and the third upright plate 17 provide a strong bending section, which can effectively resist the bending moment and torque transmitted by the crossbeam 2, and prevent the connection from opening deformation or plastic hinge under wind load or seismic action, thereby ensuring the overall rigidity and stability of the connection node.
[0029] In some embodiments, the first vertical plate 11, the second vertical plate 16, and the third vertical plate 17 form a channel-shaped structure, with the outer vertical edges of the first vertical plate 11 and the third vertical plate 17 bent inwards towards the inside of the channel-shaped structure. The closed or semi-closed channel-shaped structure formed by the first vertical plate 11, the second vertical plate 16, and the third vertical plate 17 creates a box-shaped cross-section with excellent bending and torsional resistance. The inward bending treatment of the outer edges of the first vertical plate 11 and the third vertical plate 17 completely eliminates the sharp burrs that may exist after the aluminum alloy profile is sheared or extruded. This not only avoids the risk of scratches to installers during operation and improves construction safety, but also makes the edges of the profile smoother and flatter.
[0030] In some embodiments, refer to Figure 6 The spring pin mounting structure includes a mounting tube 21 and a baffle 22.
[0031] The mounting tube 21 is fixedly installed inside the aluminum alloy crossbeam 2, providing a precise axial guide channel for the spring pin. The mounting tube 21 extends along the length of the aluminum alloy crossbeam 2, ensuring that the mounting axis of the spring pin is theoretically parallel to the axis of the pin hole on the crossbeam 2 and the column 1, fundamentally avoiding jamming or uneven force distribution of the spring pin due to misalignment of the mounting angle.
[0032] The baffle 22 is fixedly installed inside the mounting tube 21, providing a clear mechanical limit for the insertion depth of the spring pin, preventing it from being over-inserted or retracting, and ensuring that the length of its protruding end remains constant.
[0033] In some embodiments, the sidewall of the mounting tube 21 has a notch that extends along the length of the mounting tube 21. The notch provides a direct viewing window into the internal space of the mounting tube 21. During the insertion of the spring pin into the mounting tube 21, the operator can directly observe through the notch whether the head of the spring pin or the positioning mark has reached the correct position defined by the stop plate 22.
[0034] In some embodiments, the inner side of the aluminum alloy beam 2 has a second connecting plate 23 and a fourth upright plate 24; the second connecting plate 23 and the fourth upright plate 24 are parallel to each other and are both perpendicular to the side wall of the aluminum alloy beam 2. The vertical dimension of the fourth upright plate 24 is smaller than that of the aluminum alloy beam 24. The second connecting plate 23, the fourth upright plate 24 and the side wall of the aluminum alloy beam 2 form a slot structure, which provides a three-dimensional enclosing slot for the insertion part 32 of the aluminum alloy connector 3. After insertion, the insertion part 32 can be constrained in multiple directions, effectively limiting the rotation and movement of the connector in the plane.
[0035] In some embodiments, the cross-section of the snap-fit portion 31 is a C-shaped structure or a U-shaped structure.
[0036] In some embodiments, the insert 32 has a flat plate structure, and the portion of the insert 32 that contacts the slot structure has a boss. The boss changes the contact between the insert 32 and the slot structure from a large surface contact to a local small surface contact, ensuring a tight and wobbly connection between the connector 3 and the crossbeam 2.
[0037] In some embodiments, the aluminum alloy column 1 has two symmetrically arranged right-angle connecting parts 13, which constitute the main bending flange of the column section and can efficiently resist bidirectional bending moments from inside and outside the curtain wall plane; the two right-angle connecting parts 13 are connected by a first connecting plate 14, which acts as an effective web, ensuring the coordinated work of the two right-angle parts, and together forming an I-shaped or nearly closed box-shaped stress section with a high moment of inertia. The inner sidewall of the first column plate 11 has a reinforcing part 12.
[0038] In some embodiments, refer to Figure 5 The spring pin includes a pin 41 and a spring 42. The spring 42 is sleeved on the pin 41 and one end of the spring 42 is engaged with the step of the pin 41.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention.
