[0030] The elastic self-propelled anti-slip structure 6 is arranged inside the rectangular hollow part 2 301 of the T-shaped back seat 3. The elastic self-propelled anti-slip structure 6 is used to deform and connect with the C-shaped support beam 2 when the T-shaped back seat 3 contacts the wall.

[0031] Embodiment 2, based on embodiment 1, Figure 5 and Figure 6 It is shown that the symmetrical L-shaped corner seat 1 is composed of a square center column 101, an aluminum alloy profile arm 102, and a right-angle connection seat 103. The aluminum alloy profile arm 102 is provided in four pieces, two of which are welded and fixed on the outer wall of one side of the square center column 101, and the other two aluminum alloy profile arms 102 are fixed on the outer wall of the other side of the square center column 101. The right-angle connection seat 103 is provided at one of the corners of the square center column 101, and is used to bolt two vertical aluminum alloy profile arms 102.

[0032] When using the symmetrical L-shaped corner seat 1, the staff takes out the square center column 101, the aluminum alloy profile arm 102, and the right-angle connection seat 103 in sequence. At this time, the two aluminum alloy profile arms 102 are symmetrically welded and fixed on the left and right outer walls of the square center column 101, and the right-angle connection seat 103 is fixed to the square center column 101 and the aluminum alloy profile arm 102 through the stainless steel back bolt 5, thereby forming a stable L-shaped corner seat. The symmetrical structural design can effectively distribute the vertical and horizontal loads from the curtain wall panel. The load will not be concentrated at a certain point, but will be evenly distributed to the wall through the corner seat, thereby avoiding structural damage or material fatigue caused by excessive local load;

[0033] The T-shaped back seat 3 is arranged on one side outer wall of two aluminum alloy profile arms 102 in the same direction, and a plurality of stainless steel back bolts 5 for connecting with the aluminum alloy profile arms 102 are installed on one side outer wall of the T-shaped back seat 3, and a gap portion 104 is arranged between the two aluminum alloy profile arms 102 in the same extension direction, and a hole-carrying boss 302 is integrally formed on one side outer wall of the T-shaped back seat 3 close to the aluminum alloy profile arm 102, and the hole-carrying boss 302 extends to the inside of the gap portion 104; the symmetrical L-shaped angle seat 1 to be assembled After the fixing is completed, the staff makes the T-shaped back seat 3 between the two aluminum alloy profile arms 102 in the same direction, that is, the perforated boss 302 on the outer wall of one side of the T-shaped back seat 3 is inserted into the gap 104. At this time, the ends of the aluminum alloy profile arm 102 and the T-shaped back seat 3 overlap and the hole positions overlap. Finally, the stainless steel back bolt 5 is used to fix the T-shaped back seat 3 and the aluminum alloy profile arm 102. At this time, the T-shaped back seat 3 provides a strong longitudinal support force on the wall, thereby ensuring the stability of the curtain wall panel in the longitudinal direction;

[0034] The C-shaped joist 2 is provided with a through hole 204 concentric with the perforated boss 302, and one end of the expansion bolt 4 passes through the through hole 204 and the perforated boss 302 in sequence;

[0035] When the C-shaped joist 2 is slidably assembled with the two aluminum alloy profile arms 102 in the same extension direction, the center points of the rectangular hollow portion 1 202 and the rectangular hollow portion 2 301 are in a concentric state, and at this time, the end of the expansion bolt 4 also passes through the C-shaped joist 2, the through hole 204, the perforated boss 302, and the outside of the T-shaped back seat 3 in sequence and is connected to the wall. Due to the heavy weight of the curtain wall panel, the support of the bottom edge of the curtain wall panel by the C-shaped joist 2 effectively prevents the curtain wall panel from sagging or tilting, thereby improving the overall stability.

[0036] Embodiment 3, based on embodiment 2, Figure 7 It is shown that the top wall and the bottom wall of the C-shaped support beam 2 are both provided with ribs for sliding cooperation with the aluminum alloy profile arm 102, the left and right outer walls of the C-shaped support beam 2 are both provided with a plurality of column holes extending to the inside of the U-shaped groove 201, and the left and right inner walls of the rectangular hollow part 202 are both provided with positioning holes 203 for connecting with the elastic self-propelled anti-slip structure 6.

[0037] Embodiment 4, based on embodiment 3, Figure 8 and Fig. 9 The elastic self-propelled anti-slip structure 6 includes a U-shaped frame 601 fixed inside the rectangular hollow part 301, T-shaped pins 607 slidably installed on both sides of the U-shaped frame 601, and a central double-slope trapezoidal platform 608 fixed at the same end of the two T-shaped pins 607. The central double-slope trapezoidal platform 608 and the U-shaped frame 601 are elastically connected. Side plates 602 are fixed on the left and right outer walls of the U-shaped frame 601, and a convex plate 604 is slidably installed on the outer wall of one side of the side plate 602 through a guide. The convex plate 604 A convex portion 605 is installed on the outer wall of one side away from the central double-slope trapezoidal platform 608, and the convex portion 605 and the positioning hole 203 are concentric with each other. A side trapezoidal platform 606 is integrally formed on the outer wall of the convex plate 604 on the side away from the convex portion 605. The side trapezoidal platform 606 and the central double-slope trapezoidal platform 608 are slidably matched. The guide member is a hollow column sleeve fixed on the outer wall of one side of the side plate 602 and a guide column 603 slidably installed inside the hollow column sleeve, and one end of the guide column 603 is fixedly connected to the outer wall of one side of the convex plate 604;

[0038] A coil spring 609 is installed on one end of the surface of the T-shaped pin 607, one end of the coil spring 609 is fixedly connected to the outer wall of one side of the central double-slope trapezoidal platform 608, and the other end of the coil spring 609 is fixedly connected to the outer wall of one side of the U-shaped frame 601. After the symmetrical L-shaped corner seat 1, C-shaped joist 2, and T-shaped back seat 3 are assembled and contacted with the wall, the T-shaped pin 607 will be squeezed between the T-shaped back seat 3 and the wall and slide, so that the T-shaped pin 607 and the central double-slope trapezoidal platform 608 slide toward the direction of the symmetrical L-shaped corner seat 1, and the coil spring 609 is in a stretched state during this process; since the central double-slope trapezoidal platform 608 is T When pushed by the pin rod 607, the slope walls on both sides of the central double-slope trapezoidal platform 608 force the convex plate 604 and the round convex part 605 to gradually move away from the side plate 602 through the side trapezoidal platform 606. The side plate 602 and the guide column 603 guide and support the sliding of the expansion bolt 4 until the round convex part 605 is inserted into the positioning hole 203. The round convex part 605 and the positioning hole 203 are used to connect the T-shaped back seat 3 and the C-shaped support beam 2, so as to prevent the C-shaped support beam 2 from sliding in the extension direction of the aluminum alloy profile arm 102. Therefore, through the elastic effect, the curtain wall panel can automatically adjust its position when subjected to external force, so as to remain in place and avoid falling accidents.

[0039] When using the embodiment of the present application, first check whether all construction materials and tools are complete, including the symmetrical L-shaped corner seat 1, C-shaped joist 2, T-shaped back seat 3, expansion bolts 4 and required installation tools, such as bolt wrenches, measuring instruments, and spirit levels, to ensure that all components are intact and meet the design requirements, and confirm that the quality of the materials is qualified. At the same time, according to the design drawings and measurement data, the installation positions of the symmetrical L-shaped corner seat 1, C-shaped joist 2 and T-shaped back seat 3 are calibrated. During this process, the staff needs to ensure that the placement of each component is reasonable according to the corner shape of the wall and the installation requirements of the curtain wall panel to meet the support requirements of the curtain wall panel. According to the connection requirements, the staff clamps the two T-shaped back seats 3 on the left and right outer walls of the symmetrical L-shaped corner seat 1 respectively, and uses the stainless steel back bolts 5 to firmly bolt the symmetrical L-shaped corner seat 1 and the T-shaped back seat 3, and makes the two C-shaped joists 2 installed on the left and right inner walls of the symmetrical L-shaped corner seat 1 in a sliding manner, until the symmetrical L-shaped corner seat 1, the C-shaped joist 2, and the T-shaped back seat 3 are assembled, and then fix the connection components to the wall. When fixing, the staff makes the T-shaped back seat 3 in close contact with the wall, and the installation position meets the design requirements to avoid any deviation, that is, use a level to ensure its levelness to avoid To prevent subsequent installed parts from being unstable due to imbalance, the elastic self-propelled anti-slip structure 6 will form effective contact with the wall and deform during this process, and the elastic self-propelled anti-slip structure 6 will be used to provide protection for the connection and fixation of the T-shaped back seat 3 and the C-shaped joist 2; after the symmetrical L-shaped corner seat 1, the C-shaped joist 2, and the T-shaped back seat 3 are connected to each other through the stainless steel back bolt 5 and the elastic self-propelled anti-slip structure 6, the symmetrical L-shaped corner seat 1 is attached to the corner area of ​​the L-shaped wall, and the expansion bolts 4 are used to firmly fix the C-shaped joist 2, the T-shaped back seat 3, and the symmetrical L-shaped corner seat 1 to the wall. At this time, it is still necessary to check again. Check the horizontality of the symmetrical L-shaped corner seat 1 to ensure its accurate position, and the installation of the expansion bolt 4 needs to ensure that each bolt is tightened in place to avoid loose connection due to improper tightening; after the installation is completed, check whether the connection of each component is firm to ensure that the T-shaped back seat 3, the symmetrical L-shaped corner seat 1 and the C-shaped support beam 2 are not loose or displaced. At this time, the U-shaped grooves 201 at the top and bottom ends of the C-shaped support beam 2 can support the curtain wall panel, and each curtain wall panel on the C-shaped support beam 2 supports a curtain wall panel. At this time, the two adjacent curtain wall panels can be connected and limited to prevent the curtain wall panels from being displaced or falling off under the action of external forces.
