[0044] Embodiment 1

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a freely detachable pin-type curtain wall system comprises: an aluminum alloy column 1, an aluminum alloy beam 2 and a connecting assembly, wherein the aluminum alloy beam 2 is connected to the aluminum alloy column 1 through the connecting assembly; the aluminum alloy column 1 serves as a vertical supporting member of the curtain wall system, and the aluminum alloy beam 2 serves as a horizontal supporting member of the curtain wall system, and is connected to the aluminum alloy column 1 through the connecting assembly.

[0046] The connecting component includes multiple elastic components, the fixed ends of the elastic components are connected to the aluminum alloy beam 2, and the aluminum alloy column 1 is provided with connecting openings corresponding to the positions of the elastic components; when connecting, the elastic components extend from the aluminum alloy beam 2 and are inserted into the connecting openings.

[0047] A plurality of mounting openings are arranged on the connecting end surface of the aluminum alloy cross beam 2 and the aluminum alloy column 1 , and the central axis of the mounting opening is perpendicular to the aluminum alloy column 1 ; the mounting opening is a cylindrical hole.

[0048] The elastic component includes: a pin seat 6, a spring 7, a pin head 8 and a blocking plate 9.

[0049] The pin seat 6 is fixed in the installation opening; it is used to block the inner end of the installation opening and provide a support point for the spring 7 to prevent the spring 7 from escaping from the rear end of the installation opening, and a thread is set on the outer side of the pin seat 6 to adjust the position of the pin seat 6 in the installation opening through the thread.

[0050] The spring 7 is arranged in the installation opening, and the inner end of the spring 7 abuts against the pin seat 6; the pin head 8 is arranged in the installation opening and can move along the central axis of the installation opening, the inner end of the pin head 8 abuts against the outer end of the spring 7, and the spring 7 applies an outward force to the pin head 8;

[0051] During connection, the outer end of the spring pin head 8 is inserted into the connection opening, and the inner end of the spring pin head 8 is located in the installation opening.

[0052] In order to ensure that the spring pin head 8 does not pop out excessively during installation, a blocking plate 9 is provided on the end surface, and a blocking hole corresponding to the installation opening position is provided on the blocking plate 9. The blocking plate 9 is fixed to the connecting end surface of the aluminum alloy cross beam 2 by fixing screws 11, and the fixing screws 11 are located on the side of the aluminum alloy cross beam 2;

[0053] The blocking hole includes a large diameter hole and a small diameter hole, the large diameter hole is connected to the small diameter hole, and the line between the center of the large diameter hole and the center of the small diameter hole is perpendicular to the central axis of the pin head 8;

[0054] The spring pin head 8 includes a large diameter section and a small diameter section, the inner end of the large diameter section is connected to the spring 7, the outer end of the large diameter section is fixedly connected to the inner end of the small diameter section, the diameter of the small diameter section is smaller than the diameter of the small diameter hole, the diameter of the large diameter section is larger than the diameter of the small diameter hole, and the diameter of the large diameter section is smaller than the diameter of the large diameter hole;

[0055] When connecting, the small diameter section is inserted into the mounting opening.

[0056] During the installation process, the pin holder 6 is first screwed into the pre-opened hole of the aluminum alloy cross beam 2, and then the spring 7 and the pin head 8 are installed in sequence, and the pin head 8 is limited and fixed by the blocking plate 9. When limiting the position, the entire pin head 8 is coaxially arranged with the small diameter hole, and the entire pin head 8 is located in the installation opening by external force. For example, a mounting metal plate is configured. Before installation, the mounting metal plate is attached to the end face of the aluminum alloy cross beam 2. When the aluminum alloy cross beam 2 is aligned with the aluminum alloy column 1, the mounting metal plate is pulled out, and the elastic force of the spring 7 causes the pin head 8 to be inserted into the connection opening of the column to achieve mechanical connection and fixation. Therefore, the pin holder 6 is located in the small diameter hole at this time. After the small diameter hole and the large diameter section are clamped in the column, the entire pin head 8 is prevented from extending out of the installation opening, so that half of the pin head 8 is in the aluminum alloy column 1 and half is in the aluminum alloy cross beam 2, and fixation is achieved.

[0057] When disassembly is required, loosen the fixing screws 11 of the sealing plate 9 and the aluminum alloy crossbeam 2, and then pull the sealing plate 9 to finally make the spring pin head 8 coaxial with the large diameter hole. The limiting effect of the sealing plate 9 on the spring pin head 8 can be released. Under the action of the spring 7, the entire spring pin head 8 pops out and enters the aluminum alloy column 1, making it convenient to dismantle the crossbeam.

[0058] In order to realize the above-mentioned installation and disassembly process, the depth of the installation opening and the depth of the connecting opening need to be greater than the length of the pin head 8, and the diameter of the connecting opening and the diameter of the installation opening need not be less than the maximum diameter of the pin head 8.

[0059] Preferably, the pin seat 6, the spring 7, the pin head 8 and the blocking plate 9 are all made of aluminum alloy; and the fixing screw 11 is an automatic self-drilling screw.

[0060] Embodiment 2

[0061] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in order to detect whether the elastic component is correctly installed in place during the installation process and ensure that the system is firmly stressed and structurally safe, the connection component in this embodiment also includes a detection component, which is fitted on the aluminum alloy column 1 and is located at the connection surface between the aluminum alloy column 1 and the aluminum alloy beam 2.

[0062] The detection component includes a double-sided tape 10 and a detection aluminum foil 18. The detection aluminum foil 18 is attached to the aluminum alloy column 1 through the double-sided tape 10, and the detection aluminum foil 18 covers the connecting opening; the double-sided tape 10 has an adhesive tape function, which is used to fix the detection aluminum foil 18 on the aluminum alloy column 1. However, in actual use, it is necessary to minimize the use of the double-sided tape 10 to avoid damage to the detection aluminum foil 18 when pulling out the detection aluminum foil 18, thereby affecting the detection results.

[0063] When connected, the elastic component pierces the detection aluminum foil 18.

[0064] Therefore, it is possible to confirm whether the spring pin head 8 is fully inserted into the connection opening by observing the falling off of the detection strip on the detection aluminum foil 18. If the spring pin head 8 is fully inserted, the detection strip on the detection aluminum foil 18 will be punctured and fall off.

[0065] By pulling out the detection aluminum foil 18 from between the aluminum alloy column 1 and the aluminum alloy beam 2, if the detection strip completely falls off, it means that the spring pin head 8 has been correctly installed in place; if the detection strip does not completely fall off, it means that the spring pin head 8 has not completely penetrated into the column and needs to be reinstalled.

[0066] In order to better detect and avoid errors, a first plane is set, and the projections of multiple connecting openings on the first plane do not overlap. The first plane is a plane perpendicular to the first direction, and the first direction is the direction in which the detection aluminum foil 18 is pulled out from between the aluminum alloy column 1 and the aluminum alloy beam 2.

[0067] The projections of the multiple connection openings on the first plane do not overlap, which can ensure that the detection strip of each connection opening exists independently, avoid overlapping, and improve the accuracy of detection.

[0068] In practice, the hardness of the aluminum foil can be increased, and strip holes can be pre-opened on the aluminum foil, and the detection strip can be covered in the strip holes. After the spring pin head 8 is inserted into the strip hole, the detection strip will be destroyed, and in the process of pulling out the detection aluminum foil 18, the entire detection strip will be destroyed along the strip hole. After pulling out the detection film, you only need to observe whether the detection strip at the corresponding position falls off to know whether the stainless steel spring pin head 8 at the corresponding position has entered the column.

[0069] If the detection strip is not damaged, it proves that the stainless steel spring pin at that position has not been fully inserted into the column, so the beam needs to be removed and reinstalled.

[0070] Embodiment 3

[0071] like Figure 1 and Figure 2 As shown, the glass panel 3 is fixed on the aluminum alloy beam 2 by an aluminum alloy glass pressure plate 4 and an aluminum alloy buckle cover 5, an EPDM glass inner rubber strip 12 is arranged between the inner side surface of the glass panel 3 and the aluminum alloy beam 2, an EPDM glass outer rubber strip 13 is arranged between the outer side surface of the glass panel 3 and the aluminum alloy glass pressure plate 4, and a silicone weather-resistant sealant 17 and a foam strip 16 are arranged between the end surface of the glass panel 3 and the aluminum alloy beam 2.

[0072] The aluminum alloy buckle cover 5 is connected to the aluminum alloy cross beam 2 through a machine screw 15. The aluminum alloy buckle cover 5 is arranged on the outer side of the aluminum alloy glass pressure plate 4, and applies a force toward the aluminum alloy cross beam 2 to the aluminum alloy glass pressure plate 4 and the glass panel 3. A through-length heat-breaking strip 14 is arranged between the machine screw 15 and the aluminum alloy buckle cover 5, the aluminum alloy glass pressure plate 4 and the aluminum alloy cross beam 2.

[0073] The aluminum alloy glass pressing plate 4 is used to fix the inner side of the glass panel 3 to ensure a firm connection between the glass panel 3 and the aluminum alloy cross beam 2. The aluminum alloy buckle cover 5 is connected to the aluminum alloy cross beam 2 by means of a machine screw 15 and is disposed on the outer side of the aluminum alloy glass pressing plate 4. The aluminum alloy buckle cover 5 applies a force to the aluminum alloy glass pressing plate 4 and the glass panel 3 toward the aluminum alloy cross beam 2 to further stabilize the glass panel 3.

[0074] In order to enhance the air tightness and waterproofness of the system, a multi-layer sealing component is arranged between the glass panel 3 and the aluminum alloy cross beam 2 and the aluminum alloy glass pressure plate 4: the EPDM glass inner rubber strip 12 is arranged between the inner side of the glass panel 3 and the aluminum alloy cross beam 2, which plays a sealing and buffering role to prevent air and moisture from entering. The EPDM glass outer rubber strip 13 is arranged between the outer side of the glass panel 3 and the aluminum alloy glass pressure plate 4 to further provide sealing protection. The silicone weatherproof sealant 17 is filled between the end face of the glass panel 3 and the aluminum alloy cross beam 2 to provide long-term weather resistance and sealing effect. The foam strip 16 is used in conjunction with the silicone weatherproof sealant 17 to enhance the sealing performance and provide a certain buffering and heat insulation effect.

[0075] The full-length heat-insulating strip 14 is arranged between the machine screw 15 and the aluminum alloy buckle cover 5, the aluminum alloy glass pressure plate 4 and the aluminum alloy crossbeam 2 to provide a heat insulation function, reduce the thermal bridge effect, and improve the thermal insulation performance of the system.

[0076] The glass panel 3 is fixed to the aluminum alloy cross beam 2 by the aluminum alloy glass pressure plate 4 and the aluminum alloy buckle cover 5, and a multi-layer sealing component (such as EPDM strip, silicone weatherproof sealant 17 and foam strip 16) is used to provide excellent sealing and protection effects. The aluminum alloy buckle cover 5 is connected to the cross beam by a machine screw 15, and exerts a force to ensure the stability of the glass panel 3. The use of the full-length thermal insulation strip 14 improves the thermal insulation performance of the system. This design not only ensures the stable installation of the glass panel 3, but also improves the air tightness, waterproofness and thermal insulation performance of the curtain wall system.
