Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of glass curtain walls, and in particular to a heat-insulating building glass curtain wall structure. Background Technology
[0002] Typical glass curtain walls consist of glass installed on a support frame, with the main stable structure exposed or having poor stability. To ensure its heat insulation and strength, multi-layered glass or insulated glass is usually used, which results in either heavy weight or easy air leakage, causing quality problems. Utility Model Content
[0003] This invention aims to overcome the shortcomings of existing technologies, such as insufficient stability of exposed structures and the inability to balance glass weight and quality. It provides a heat-insulating building glass curtain wall structure that features a concealed structure, improved stability, reduced glass weight, and improved quality.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A thermally insulated building glass curtain wall structure, comprising:
[0006] The frame serves as the supporting structure for the glass curtain wall;
[0007] Insulating glass is placed within a frame that surrounds the sides of the insulating glass. The insulating glass comprises two single-layer glass panes and an intermediate glass pane. The two single-layer glass panes are respectively placed on the front and rear end faces of the intermediate glass pane. The cross-sectional shape of the intermediate glass pane is wavy. All single-layer glass panes are fixedly connected to the intermediate glass pane.
[0008] A baffle frame is placed inside the frame and on the rear end face of the heat-insulating glass. The outer side of the baffle frame is fixedly connected to the inner side of the frame, and the heat-insulating glass is snapped into the frame through the baffle frame.
[0009] A fixing bracket is placed on the front end face of the heat-insulating glass, wherein the inner side of the fixing bracket is shorter than the outer side of the heat-insulating glass;
[0010] Several expansion tubes are evenly distributed around the heat-insulating glass. One end of each expansion tube passes through a fixing frame and is placed inside the frame. The tail end of each expansion tube is divided into several pieces and evenly distributed around the center of the expansion tube.
[0011] Several fixing pins correspond one-to-one with the expansion tubes. The fixing pins pass through the front end of the expansion tubes and are placed inside the frame. The fixing pins are coaxial with the expansion tubes. The fixing frame is connected to the frame through the cooperation of the fixing pins and the expansion tubes. The expansion tubes are snapped into the frame by the fixing pins.
[0012] The glass uses three layers, but the middle layer is wavy, allowing air to be filled between the two single-layer glass panes. The middle layer provides support, preventing deformation due to air leakage. The thickness of the insulated glass increases slightly with minimal weight increase, thus improving its insulation performance. The insulated glass is then installed inside the frame and concealed by a retaining frame. The other side of the insulated glass is then secured with a fixing bracket, and expansion tubes and fixing nails are used to fix the bracket to the frame. Finally, adhesive is used to fix it again where necessary to improve stability. This achieves the goal of concealing the structure, improving stability, reducing glass weight, and maintaining quality simultaneously.
[0013] Preferably, the frame is provided with several slots evenly distributed on the front end face of the frame, each slot corresponding to an expansion tube. The fixing bracket is provided with several mounting holes, each corresponding to a slot, and the mounting holes and slots are coaxial. The expansion tube passes through the mounting hole and is placed in the slot, and is secured to the inner wall of the slot by a fixing pin. Both the mounting holes and the slots are for facilitating the installation of the expansion tube.
[0014] Preferably, the slot has several retaining rings (first type) evenly surrounding the inner wall of the slot. Each retaining ring has a triangular cross-section with its vertical side positioned behind the diagonal. The retaining rings are fixedly connected to the inner wall of the slot. The outer surface of the expansion tube has several retaining rings (second type) evenly surrounding it. Each retaining ring (second type) corresponds to one retaining ring (first type), and its cross-section is also triangular with its vertical side positioned in front of the diagonal. After the fixing pin passes through the mounting hole and is placed inside the expansion tube, one retaining ring (second type) is placed between two retaining rings (first type). The expansion tube is then engaged with the inner wall of the slot through the cooperation of retaining rings (first and second types). The retaining rings (first and second types) are used to fix the expansion tube.
[0015] Preferably, the front end face of the fixing frame has several grooves, each corresponding to a mounting hole and coaxial with the mounting hole. One end of the expansion tube has an annular stop that surrounds the outer surface of the expansion tube. The annular stop and the expansion tube are integrally formed. The annular stop is placed within a groove, and the expansion tube is engaged with the fixing frame via the annular stop. The fixing pin passes through the groove and is placed inside the expansion tube. The cooperation between the annular stop and the groove allows the expansion tube to secure the fixing frame.
[0016] Preferably, the heat-insulating glass has a sealing edge on its outer edge, which wraps around the edges of the single-pane glass and the intermediate glass. The sealing edge is fixedly connected to both the single-pane glass and the intermediate glass, and is placed within the frame between the fixing bracket and the retaining frame. The sealing edge facilitates the connection between the single-pane glass and the intermediate glass, as well as the sealing of the inert gas between the single-pane glass.
[0017] Preferably, both the mounting bracket and the baffle frame are equipped with buffer strips. These buffer strips are fixedly connected to the rear end face of the mounting bracket and the front end face of the baffle frame, respectively. The buffer strips on both the mounting bracket and the baffle frame contact the two single-pane glass panes. The buffer strips reduce the impact of the baffle frame and mounting bracket on the single-pane glass panes.
[0018] Preferably, the fixing pin is placed in the groove after installation, with its head not exceeding the height of the fixing frame. This concealed fixing pin design is both aesthetically pleasing and safe.
[0019] The beneficial effects of this utility model are: the structure is concealed and improves stability; the weight of the glass is reduced while maintaining quality; the mounting holes and slots are for the convenient installation of the expansion tube; the second and first retaining rings are for fixing the expansion tube; the combination of the annular stop and the groove allows the expansion tube to be fixed to the fixing frame; the sealing edge facilitates the connection between the single-layer glass and the intermediate glass, as well as the sealing of the inert gas between the single-layer glass; the buffer strip can reduce the impact of the baffle frame and the fixing frame on the single-layer glass; the fixing nails do not protrude, which is both beautiful and safe.

[0026] like Figure 1 and Figure 3 As shown, there are several slots 9 evenly distributed on the front end face of the frame 1. The slots 9 correspond one-to-one with the expansion tubes 4. The fixing frame 3 is provided with several mounting holes 10, which correspond one-to-one with the slots 9. The mounting holes 10 and the slots 9 are coaxial. The expansion tubes 4 pass through the mounting holes 10 and are placed in the slots 9. The expansion tubes 4 are engaged with the inner wall of the slots 9 by fixing nails 5.
[0027] like Figure 3 As shown, there are several retaining rings 11 inside the slot 9. The retaining rings 11 are evenly wrapped around the inner wall of the slot 9. The cross-sectional shape of the retaining rings 11 is triangular, and the vertical side of the triangle of the retaining rings 11 is placed behind the diagonal. The retaining rings 11 are fixedly connected to the inner wall of the slot 9. Several retaining rings 2 are evenly wrapped around the outer surface of the expansion tube 4. The retaining rings 2 correspond one-to-one with the retaining rings 11.
