The stability, safety and durability of the curtain wall system directly depend on the rationality of its connection structure design. The connection structure must simultaneously bear multiple forces such as the self-weight of the curtain wall panel, wind load, and temperature deformation, and must also meet the needs of convenient construction and subsequent maintenance.

[0003] In existing technologies, the connection between curtain wall panels and the main frame mostly adopts a fixed structure, which directly locks the outer frame of the curtain wall panel to the columns or crossbars with a large number of bolts. This method has low installation efficiency, and bolt holes need to be aligned point by point during construction. Especially in high-altitude working environments, the operation process is cumbersome and the construction period is greatly extended. Moreover, after the curtain wall panels are installed, the sealing effect of the gaps between adjacent panels is poor, and dust and debris easily accumulate in the gaps. This not only further accelerates the aging of the seals, but also affects the cleanliness and aesthetics of the curtain wall, and increases the workload of later cleaning and maintenance. Therefore, this application proposes a connection structure for panel-type building curtain walls. Utility Model Content

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-9This utility model provides a technical solution: a connection structure for a panel-type building curtain wall, including columns 11 and horizontal bars 12. Two columns 11 are arranged vertically and symmetrically distributed left and right. Two horizontal bars 12 are arranged horizontally and symmetrically distributed top and bottom between the two columns 11. The horizontal bars 12 and columns 11 form a grid-like frame. This grid-like frame, constructed by the two symmetrical columns 11 and the two symmetrical horizontal bars 12, provides a stable installation foundation for the curtain wall panel 2, effectively bearing the self-weight of the curtain wall panel 2, wind loads, and other external forces. Integrated fasteners 13 are welded to the sides of the columns 11 and at the connection points of the horizontal bars 12. The two ends of the horizontal bars 12 are respectively inserted into... On the corresponding fastener 13, the ends of the two horizontal bars 12 are provided with sockets 14, and each socket 14 can be fitted onto the outside of the corresponding fastener 13. A curtain wall panel 2 is installed on the front side of the column 11 and the horizontal bar 12. The curtain wall panel 2 is surrounded by an integrated outer frame 21. Sealing elements are provided around the outer frame 21. The fastener 13 and the socket 14 are used to connect the column 11 and the horizontal bar 12. The curtain wall panel 2 is connected to the frame through the outer frame 21. The connection relationship of each component is clear, which facilitates construction, assembly and later maintenance. Sealing elements are provided around the outer frame 21 to initially prevent dust, rainwater and other substances from seeping in from the gap between the curtain wall panel 2 and the frame, ensuring the basic protective performance of the curtain wall.

[0020] like Figure 2 , Figure 3 and Figure 4 As shown, the cross-section of the fixing member 13 is U-shaped. A positioning rod 132 is installed on the inner side of the vertical part of the fixing member 13. A first threaded groove is provided on the positioning rod 132. The top and bottom of the fixing member 13 away from the column 11 are provided with first through holes 133 aligned vertically. The rear sides of both ends of the crossbar 12 are provided with rod grooves 121, and the front sides of both ends of the crossbar 12 are provided with countersunk holes 122 communicating with the corresponding rod grooves 121. A second through hole is provided on the top of both ends of the crossbar 12. Hole 123, the top of the socket 14 is provided with a third through hole 142, and the size of the inner wall of the socket 14 is adapted to the size of the outer wall of the fastener 13. Through the concave design of the fastener 13, the setting of the positioning rod 132 and the first through hole 133, the corresponding opening of the upper groove 121, countersunk hole 122 and second through hole 123 of the crossbar 12, and the adaptation of the size of the outer wall of the socket 14 and the fastener 13, the components can be accurately aligned when connected, avoiding misalignment problems during assembly.

[0021] like Figure 2 , Figure 3 and Figure 4As shown, both ends of the crossbar 12 are located within the corresponding fixing members 13, and the rod grooves 121 on the rear side of both ends of the crossbar 12 are fitted onto the positioning rods 132 on the inner wall of the corresponding fixing members 13. Positioning bolts 124, threadedly connected to the first threaded groove on the positioning rod 132, are inserted into the countersunk holes 122. When the sleeve 14 is fitted onto the outside of the fixing members 13, the third through hole 142 on the sleeve 14 is vertically aligned with the first through hole 133 on the fixing members 13 and the second through hole 123 at the end of the crossbar 12. Locking bolts 15 are inserted through the third through hole 142, the first through hole 133, and the second through hole 123. Through multiple... The fixing method strengthens the connection between the column 11 and the horizontal bar 12. The horizontal bar 12 and the fixing member 13 are initially positioned by the cooperation of the bar groove 121 and the positioning rod 132, and then locked with the positioning bolt 124 to complete the first layer of fixing. After the sleeve 14 is fitted, the locking bolt 15 passes through the sleeve 14, the fixing member 13 and the horizontal bar 12 to achieve the second layer of fixing. This greatly improves the stability of the connection between the column 11 and the horizontal bar 12, so that it can better resist the displacement and deformation under the action of external forces, and ensure the structural stability of the entire frame. It is especially suitable for building curtain wall scenarios that need to withstand large wind loads and other external forces.

[0022] like Figure 2 , Figure 3 and Figure 4 As shown, each fastener 13 has an integral triangular reinforcing plate 131 at its top and bottom, which is connected to the column 11. Each socket 14 has a slot 141 at its top and bottom near the column 11. When the socket 14 is fitted with the fastener 13, the slot 141 on the socket 14 is inserted into the corresponding reinforcing plate 131 on the fastener 13. Through the matching design of the triangular reinforcing plate 131 and the slot 141, the overall strength and assembly accuracy of the connection structure are further enhanced. The reinforcing plate 131 utilizes the stability characteristics of a triangle to strengthen the connection between the fastener 13 and the column 11, reducing the deformation of the fastener 13 under stress. The slot 141 of the socket 14 is inserted into the reinforcing plate 131 during installation, which not only achieves precise alignment between the socket 14 and the fastener 13, avoiding installation misalignment, but also allows the reinforcing plate 131 to provide limiting support for the socket 14, forming a more stable overall load-bearing structure between the fastener 13, the socket 14 and the column 11, improving the shear and torsional resistance of the connection part.

[0023] like Figure 3 , Figure 5 and Figure 6As shown, three fixing frames are equidistantly installed on the inner side of each upright column 11, three groups of docking pieces 22 are equidistantly installed on the rear sides of the two vertical portions of the outer frame 21, each docking piece 22 is engaged in the correspondingly positioned fixing frame 16, and the fixing frames 16 on the inner side of the upright column 11 are engaged with the docking pieces 22 of the outer frame 21 in one-to-one correspondence. It is not necessary to perform point-by-point bolt alignment installation around the curtain wall panel 2, which simplifies the installation process of the curtain wall panel 2 and effectively improves the overall construction efficiency.

[0024] As Figure 3 , Figure 5 and Figure 6 shown, the fixing frame 16 is arranged in a C-shape, the docking piece 22 includes an insertion plate 221 with a size adapted to the inner wall of the fixing frame 16 and two limiting blocks 222, the insertion plate 221 is fixedly connected with the outer frame 21, grooves are provided on both the top and bottom of an end of the insertion plate 221 away from the outer frame 21, the two limiting blocks 222 are respectively movably inserted into the two grooves, a spring 223 is fixedly connected between each of the two limiting blocks 222 and an inner end of the corresponding groove, a corner of the end of the limiting block 222 extending out of the groove and away from the outer frame 21 is provided as an inclined surface, one end of the limiting block 222 can extend out of the groove and abut against a side of the fixing frame 16 away from the curtain wall panel 2. The C-shaped fixing frame 16 facilitates the insertion of the insertion plate 221 in the docking piece 22, and the design of the elastic limiting block 222 in the docking piece 22 achieves the effect of "locking upon insertion": during insertion, the inclined surface of the limiting block 222 is squeezed and contracted, which facilitates the insertion plate 221 to smoothly enter the fixing frame 16; after being completely inserted, the spring 223 pushes the limiting block 222 to extend out and tightly abut against the outer side of the fixing frame 16, completing locking automatically without extra operations, which not only simplifies the installation steps, but also ensures the stability of the curtain wall panel 2 after installation.

[0025] As Figure 7 and Figure 8 shown, the sealing member includes four pressure plates 41 and four cover plates 42, the cross section of the pressure plate 41 is T-shaped, the four pressure plates 41 are respectively located around the outer frame 21, fixing blocks 17 are installed on the front sides of the two upright columns 11 and between the ends of adjacent two pressure plates 41, a notch is provided at an end of the transverse portion of each pressure plate 41, the four cover plates 42 are respectively arranged at the ends of adjacent two pressure plates 41 and located at the notches. Through the combined sealing member design of the pressure plates 41 and the cover plates 42, a double sealing defense line is constructed, which significantly improves the sealing performance of the curtain wall, effectively reduces the problems of dust accumulation and impurity accumulation in the gaps between adjacent outer frames 21, not only ensures the cleanliness and aesthetics of the curtain wall, but also delays the aging speed of the sealing member and prolongs the service life of the curtain wall.

[0026] As Figure 7 , Figure 8 and Figure 9As shown, the pressure plate 41 is tightly fitted to the edge of the outer frame 21. A first screw hole 411 is provided at both ends of the side of the pressure plate 41. In the vertical state, a first bolt 43 for threaded connection with the column 11 is inserted into the first screw hole 411 at both ends of the pressure plate 41. In the horizontal state, a first bolt 43 for threaded connection with the outer wall of the sleeve 14 is inserted into the first screw hole 411 at both ends of the pressure plate 41. By using the first bolt 43, the pressure plate 41 can be installed and fixed, so that it can be tightly fitted to the perimeter of the outer frame 21 to form an effective protective structure.

[0027] like Figure 7 , Figure 8 and Figure 9 As shown, each pressure plate 41 has a notch at its end with a slot 412. Four rods 422 are fixedly installed on the side of the cover plate 42, and the four rods 422 are respectively inserted into the slots 412 at the corresponding notches. Through the insertion and cooperation of the rods 422 and the slots 412, the position of the cover plate 42 can be positioned and installed.

[0028] like Figure 7 , Figure 8 and Figure 9 As shown, a screw groove is provided at the center of the side of the fixing block 17, and a second screw hole 421 is provided at the center of the side of the cover plate 42. A second bolt 44, which is connected to the screw groove on the corresponding fixing block 17, is inserted into the second screw hole 421. The cover plate 42 is firmly connected to the fixing block 17 on the column 11 by the second bolt 44, which further enhances the sealing stability of the seal. The fixing block 17 provides a stable fixing support point for the cover plate 42. The second bolt 44 passes through the screw groove of the cover plate 42 and connects with the screw groove of the fixing block 17, so that the cover plate 42 can be tightly pressed into the joint of the pressure plate 41, which can increase the stability of the installation of the pressure plate 41 in the seal.
