Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1-8 , the present invention provides a technical solution: a building curtain wall structure, including channel steel 1 fixed on the surface of a building wall and a decorative plate 2. As Figure 1 shown, two channel steels 1 need to be configured for each row of decorative plates 2. The two channel steels 1 are arranged in parallel on the surface of the building wall. The two channel steels 1 can be vertically or horizontally installed on the surface of the building wall. A long strip groove 101 is opened on the channel steel 1. The side of the long strip groove 101 away from the building wall is in an open shape. A plurality of connecting columns 3 are fixedly connected to the back surface of the decorative plate 2. A locking rod 4 is rotatably connected inside the connecting column 3. One end of the locking rod 4 penetrates through the side wall of the decorative plate 2 and is connected with a driving head 401. As Figures 5-6 shown, a driving groove 402 is opened on the driving head 401. The driving groove 402 is a slot in the shape of a straight line. By inserting an external straight screwdriver into the driving groove 402, the driving head 401 can be rotated, that is, the locking rod 4 is driven to rotate. The other end of the locking rod 4 penetrates through the side wall of the connecting column 3 and is connected with a stop block 5. The stop block 5 is movably clamped inside the long strip groove 101. The stop block 5 is a rectangular block. The width of the stop block 5 is not greater than the opening width of the long strip groove 101, and the length of the stop block 5 is not less than the opening width of the long strip groove 101. After the stop block 5 is clamped inside the long strip groove 101, the surface of the driving head 401 is flush with the surface of the decorative plate 2.

[0024] As Figure 1 shown, during installation, first install the two channel steels 1 on the surface of the building wall, and then rotate the locking rod 4. The locking rod 4 drives the stop block 5 to rotate, so that the length direction of the stop block 5 is parallel to the opening length direction of the long strip groove 101 (as Figure 4As shown in the figure, after the stopper 5 is placed inside the long groove 101, the locking rod 4 is rotated. At this time, the stopper 5 rotates to the horizontal state inside the long groove 101, and the upper end surface of the stopper 5 abuts against the side wall of the long groove 101, causing the stopper 5 to be locked inside the long groove 101, thereby realizing the installation of the decorative panel 2 on the building wall;

[0025] In addition, after the stopper 5 is locked inside the long groove 101, the stopper 5 can still slide inside the long groove 101, thereby adjusting the position of the decorative panel 2 along the length direction of the channel steel 1, and enabling two adjacent decorative panels 2 to be moved to a close state.

[0026] As Figure 5 shown, in order to enable the stopper 5 to abut tightly against the side wall of the long groove 101, specifically, a rubber pad 6 is provided between the bottom of the driving head 401 and the side wall of the decorative panel 2. When the driving head 401 is rotated, the driving head 401 is pressed, causing the rubber pad 6 to be in a compressed state. After the driving head 401 is rotated and the stopper 5 rotates to the horizontal state, the driving head 401 is released, and the rubber pad 6 elastically presses the driving head 401 upward. At this time, the locking rod 4 pulls the stopper 5 upward, causing the stopper 5 to be able to abut tightly against the side wall of the long groove 101. When adjusting the position of the decorative panel 2 along the length direction of the channel steel 1, a certain driving force needs to be applied to the decorative panel 2. After the driving force disappears, the position of the decorative panel 2 can be kept relatively fixed.

[0027] In order to fix the stopper 5 clamped inside the long groove 101 to prevent the locking rod 4 from rotating by itself and causing the stopper 5 to disengage from the long groove 101 and ensure the stability of the installation of the decorative panel 2, specifically, a glue injection hole 403 is provided inside the locking rod 4. The upper end of the glue injection hole 403 penetrates through the driving head 401, the lower end of the glue injection hole 403 penetrates through the stopper 5, and a glue storage groove 301 is provided between the connecting column 3 and the locking rod 4. A diversion hole 404 for communicating the glue injection hole 403 with the glue storage groove 301 is provided on the side wall of the locking rod 4.

[0028] After the decorative panel 2 is installed on the building wall through the channel steel 1, foam glue is injected into the inside of the glue injection hole 403. A part of the foam glue flows into the inside of the long groove 101 along the glue injection hole 403, and another part of the foam glue flows into the inside of the glue storage groove 301 from the diversion hole 404. After the foam glue solidifies, the foam glue flowing into the long groove 101 solidifies the stopper 5, preventing the stopper 5 from rotating and disengaging inside the long groove 101. Moreover, the foam glue flowing into the glue storage groove 301 can stick the locking rod 4 and the connecting column 3 together, preventing the locking rod 4 from rotating inside the connecting column 3, thereby further preventing the stopper 5 from rotating inside the long groove 101 and improving the installation stability;

[0029] In addition, when an external flat screwdriver is inserted into the driving groove 402 and the flat screwdriver is rotated forcefully, although the locking rod 4 and the stopper 5 are adhered by foam adhesive, the driving head 401 can still be driven to rotate, which also facilitates the removal of the decorative panel 2.

[0030] As Figures 2-4 shown in FIGS. 5 and 7, in order to support the decorative panel 2, specifically, a plurality of support columns 7 are fixed on the side wall of the decorative panel 2, and a support surface 102 for supporting the support columns 7 is provided on the side wall of the channel steel 1.

[0031] As Figure 7 shown in FIG., in order to facilitate the removal of the decorative panel 2 from the channel steel 1, specifically, a plurality of support columns 7 are distributed on the center line of the decorative panel 2 perpendicular to the length direction of the channel steel 1.

[0032] When the length direction of the stopper 5 rotates to be parallel to the length direction of the long slot 101, press one end of the decorative panel 2 downward. At this time, with one end of the support column 7 supported on the support surface 102 as the fulcrum, the other end of the decorative panel 2 tilts upward, which is beneficial to disassembling the decorative panel 2 from the channel steel 1 for convenient replacement;

[0033] In addition, a sunk groove 104 is formed at the bottom of the long slot 101. When the decorative panel 2 is pressed, the stopper 5 can move towards the sunk groove 104. Then, the stopper 5 has enough space to move, increasing the tilting angle of the decorative panel 2 upward to facilitate the removal of the decorative panel 2 more conveniently.

[0034] As Figure 2 shown in FIG., in order to further increase the strength of the decorative panel 2 and prevent the decorative panel 2 from being sunken and deformed, specifically, a bracket 8 is fixedly connected to the middle of the decorative panel 2, and both ends of the bracket 8 are respectively fixed on the side walls of two support columns 7.

[0035] Specifically, adjacent decorative panels 2 are butted through an inclined wall, and a sealing gasket 9 is arranged between adjacent decorative panels 2.

[0036] Specifically, reinforcing ribs 103 for increasing the strength of the channel steel 1 are evenly distributed on the side wall of the channel steel 1.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
