[0002] Dry-Hung Ceramic Facade is a building exterior wall decoration system that uses ceramic tiles as finishing materials and is installed on the exterior walls of buildings through dry-hanging technology. Compared with traditional wet pasting (such as cement mortar pasting), dry-hanging technology has higher installation efficiency and better decorative effect. The characteristics of dry-hanging ceramic curtain walls include: light weight and high strength, beautiful appearance, strong weather resistance, convenient installation, thermal insulation, waterproof and moisture-proof. Dry-hanging technology directly fixes the decorative panels on the exterior wall structure through embedded parts, connectors, keels and other fixing systems without the use of wet working materials such as cement mortar. This method not only improves construction efficiency, but also reduces the quality problems caused by wet working. Therefore, dry-hanging ceramic curtain walls are widely used in exterior wall decoration of various public buildings, commercial buildings, residential buildings, etc., especially in cultural buildings and projects requiring high-end appearance. The existing dry-hanging ceramic curtain wall system generally uses vertical sleeve steel bars or metal screws to fix ceramic tiles between two layers of horizontal keels.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the relevant technologies in the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] refer to Figures 1 to 5 A ceramic tile of this embodiment, wherein at least two upper openings 1 are provided on the top of the ceramic tile, wherein a pin shaft 2 which can be extended and retracted in the vertical direction is provided in the upper opening 1, wherein the length of the pin shaft 2 is less than the vertical height of the ceramic tile, and the pin shaft 2 includes two modes: a hanging mode and a disassembly mode; when the pin shaft 2 is in the hanging mode, the upper part of the pin shaft 2 extends above the top surface of the ceramic tile, and the lower part of the pin shaft 2 is located in the upper opening 1; when the pin shaft 2 is in the disassembly mode, the entire pin shaft 2 sinks and retracts into the upper opening 1 of the ceramic tile itself;

[0029] The bottom of the ceramic tile is provided with at least two lower openings 3. When the pin shaft 2 is in the hanging mode, the upper part of the pin shaft 2 of the next layer of ceramic tiles is inserted into the lower opening 3 of the previous layer of ceramic tiles;

[0030] The hole positions of the upper opening 1 and the lower opening 3 are aligned up and down, and the number of holes corresponds to each other; the pin shaft 2 is extended and retracted in the upper opening 1, so that the pin shaft 2 can be locked and hung from bottom to top or released and disassembled. At the same time, when the ceramic tiles are arranged in multiple layers, when the pin shaft 2 of the lower layer is inserted upward into the lower opening 3 of the upper layer, the ceramic tiles are locked in sequence, so that the position of the ceramic tiles arranged in multiple layers is fixed; when the pin shaft 2 of the lower layer is pulled downward from the lower opening 3 of the upper layer, the lifting hole 14 is lifted and horizontally rotated from the range of the shallow groove 10 to the deep groove 11 and dropped to The bottom of the deep groove 11 allows the pin 2 of the lower layer to be completely pulled out and disengaged from the lower opening 3 of the upper layer, and the ceramic tiles of the upper and lower layers are unlocked in sequence, thereby realizing the unlocking of the positions of the ceramic tiles arranged in multiple layers, and all the ceramic tiles can be removed; when the pin 2 of the lower layer of one or several ceramic tiles is pulled downward out of the lower opening 3 of the upper layer, and the pin 2 in the lower opening 3 of the ceramic tile is also pulled out, the position of the ceramic tile can be unlocked, so that the ceramic tile can be removed for replacement and maintenance. During replacement and maintenance, the positions of other ceramic tiles that have not been replaced remain fixed and are not affected by the replacement of the ceramic tiles.

[0031] Furthermore, the upper opening 1 and the lower opening 3 are located at the upper and lower ends of the same through hole 4 on the ceramic tile, and a connecting sleeve 5 is fixedly arranged in the through hole 4, and sleeve holes 6 are respectively arranged at the upper and lower ends of the connecting sleeve 5, and the aperture of the sleeve hole 6 matches the diameter of the pin shaft 2; the upper opening 1 and the lower opening 3 are located at the two ends of the through hole 4, which makes the ceramic tile processing simpler and more convenient, and ensures that the hole positions of the upper opening 1 and the lower opening 3 correspond, which is convenient for the insertion and withdrawal of the pin shaft 2. The connecting sleeve 5 and the sleeve hole 6 in the through hole 4 can be installed in a subsequent installation manner, and the sleeve hole 6 matches the diameter size of the pin shaft 2, which improves the installation accuracy of the insertion and withdrawal of the pin shaft 2, so that the ceramic tile fixing effect is better and the installation accuracy is higher.

[0032] Furthermore, the pin shaft 2 and the connecting sleeve 5 are both made of metal materials, and the materials of ceramic tiles include: ceramic, glass, metal, stone, PVC; the pin shaft 2 and the connecting sleeve 5 made of metal materials are easier to process and produce and can be recycled and reused multiple times when the ceramic tiles are worn out; and the pin shaft 2 and the connecting sleeve 5 can be installed on various ceramic tiles such as ceramic, glass, metal, stone, PVC, etc.

[0033] Furthermore, a cylindrical cavity 7 is provided in the connecting sleeve 5, and the diameter of the cavity 7 is larger than the diameter of the sleeve hole 6; an annular boss 8 protruding radially outward is provided at the bottom of the pin shaft 2, and the diameter of the annular boss 8 is larger than the diameter of the sleeve hole 6, and the diameter of the annular boss 8 is smaller than the diameter of the cavity 7; the annular boss 8 and the bottom of the pin shaft 2 are together in the cavity 7, and the annular boss 8 and the bottom of the pin shaft 2 can slide back and forth in the vertical direction of the cavity 7; the annular boss 8 cooperates with the cavity 7 so that the maximum insertion stroke of the pin shaft 2 is limited, preventing the pin shaft 2 from being excessively inserted upward, causing the lower part of the pin shaft 2 to be separated from the upper opening 1, resulting in the ceramic tile not being fixed and causing a safety hazard.

[0034] Furthermore, a horizontal axis 9 extending radially outward is provided in the middle of the pin shaft 2; a shallow groove 10 and a deep groove 11 are respectively provided on the upper surface of the ceramic tile, which are concave in the vertical direction, and the groove width and groove length of the shallow groove 10 and the deep groove 11 are respectively greater than the shaft diameter and shaft length of the horizontal axis 9, and the shallow groove 10 and the deep groove 11 are arranged horizontally staggered, and the concave depth of the deep groove 11 is greater than the concave depth of the shallow groove 10; when the pin shaft 2 is in the hanging mode, the horizontal axis 9 is rotated and settled in the shallow groove 10; when the pin shaft 2 is in the disassembly mode, the horizontal axis 9 is rotated and settled in the shallow groove 10. After rotation, it sinks in the deep groove 11; the horizontal axis 9 cooperates with the shallow groove 10 and the deep groove 11 to limit the height position of the top of the pin shaft 2 in the hanging mode and the disassembly mode, ensuring that the upper part of the pin shaft 2 is inserted into the lower opening 3 of the upper layer of ceramic tile to a sufficient depth in the hanging mode, and the pin shaft 2 is completely retracted into the upper opening 1 of the ceramic tile in the disassembly mode without affecting the disassembly and replacement operation; the staggered shallow groove 10 and the deep groove 11 prevent the pin shaft 2 from slipping from the hanging mode to the disassembly mode during use, thereby causing safety hazards.

[0035] Furthermore, the horizontal axis 9 passes through the axis of the pin shaft 2 and is symmetrically arranged on the left and right, and the offset angle of the shallow groove 10 and the deep groove 11 is 30° to 90°; the horizontal axis 9 can be set on one side, on both sides or at multiple angles. When the horizontal axis 9 is set on both sides, it can be set in a symmetrical manner, that is, the horizontal axis 9 passes through the pin shaft 2 and the lengths extending on both sides are the same, which is convenient for construction personnel to use the lifting height of the horizontal axis 9 to adjust the pin length of the pin shaft 2 to realize the conversion between the hanging mode and the disassembly mode.

[0036] Furthermore, a stop cover 12 is provided at the opening of the upper opening 1, and the stop cover 12 is in a circular ring shape, and the ring hole of the stop cover 12 is not less than the shaft diameter of the pin shaft 2; the bottom surface of the stop cover 12 is provided with a fan-shaped stop groove 13 that is recessed upward, and the angle between the two fan-shaped edges of the stop groove 13 is not less than the misalignment angle between the shallow groove 10 and the deep groove 11; the stop groove 13 is used to limit the rotation angle of the horizontal shaft 9, and at the same time ensure that the horizontal shaft 9 is always located in the shallow groove 10 or the deep groove 11 during use, ensuring that the pin shaft 2 is always switched between the hanging mode and the disassembly mode without staying in the middle position for too long;

[0037] A lifting hole 14 is provided at the end of the horizontal shaft 9 away from the pin shaft 2; the lifting hole 14 is used to utilize the narrow gap between the upper and lower ceramic tiles to use a tool to pull and hook the horizontal shaft 9 during installation and maintenance to achieve switching between the hanging mode and the disassembly mode. Before the ceramic tile to be replaced is placed into position, the tool is connected to the lifting hole 14, so that the pin shaft 2 can be lifted and rotated to the position of the shallow groove 10 from the outside of the curtain wall using the gap between the ceramic tiles.

[0038] Furthermore, the horizontal shaft 9 and the pin shaft 2 are detachably connected; the detachably connected horizontal shaft 9 and the pin shaft 2 make the connecting parts faster and more efficient during mass production and reduce production costs.

[0039] This embodiment also includes a dry-hanging ceramic tile curtain wall system that can quickly replace ceramic tiles. The dry-hanging ceramic tile curtain wall system adopts the above-mentioned ceramic tile hanging. The dry-hanging ceramic tile curtain wall system includes: a vertical keel 15 and a horizontal keel 16. The vertical keel 15 is fixedly connected to the horizontal keel 16, and at least two layers of ceramic tiles are hung between two adjacent horizontal keels 16;

[0040] The horizontal keel 16 is provided with a hanging hole 17 with a vertical rotation axis, and the hole position of the hanging hole 17 matches the hole position of the upper opening 1 and the lower opening 3 on the ceramic tile;

[0041] In the hanging mode, the pin shaft 2 of the uppermost layer of ceramic tile between the two adjacent horizontal keels 16 is fixed in the hanging hole 17 of the upper horizontal keel 16, and the hanging hole 17 of the lower horizontal keel 16 is provided with a bolt or a pin pin fixed in the lower opening 3 of the lowest layer of ceramic tile; since each ceramic tile can be conveniently and quickly installed and removed with the pin shaft connecting holes of the upper and lower layers, when any ceramic tile on the dry-hanging ceramic tile curtain wall system needs to be disassembled and maintained, the pin shaft in the lower opening 3 and the pin shaft in the upper opening of the ceramic tile are respectively pulled out to unlock the position of the ceramic tile, so that the ceramic tile can be removed for replacement and maintenance. During replacement and maintenance, the positions of other ceramic tiles that have not been replaced are kept fixed, so that the dry-hanging ceramic tile curtain wall system is not affected by the replacement of ceramic tiles; replacement and maintenance are faster and more convenient.

[0042] Furthermore, a positioning washer 18 is provided on the hanging hole 17 of the horizontal keel 16, and the inner hole diameter of the positioning washer 18 is the same as the shaft diameter of the pin shaft 2; the positioning washer 18 is used to accurately locate the matching position of the pin shaft 2 or the lower opening 3, thereby reducing the processing and production accuracy of the hanging hole 17, improving production efficiency and reducing production costs.

[0043] Example

[0044] When the ceramic tiles of the utility model are used for the dry hanging ceramic tile curtain wall system, the vertical keel 15 is connected to the main body of the building, and the horizontal keel 16 is connected to the vertical keel 15. Multiple layers of ceramic tiles can be hung between two adjacent horizontal keels 16. The lower horizontal keel 16 pushes the pin or bolt to the designed height from the hanging hole 17, and then hangs the lowest layer of ceramic tiles on the lower horizontal keel 16, so that the lower openings 3 of the lowest layer of ceramic tiles are respectively hung on the pins or bolts extending upward from the hanging holes 17 of the lower horizontal keel 16, and the pins 2 of the lowest layer of ceramic tiles are adjusted to the hanging state and extend out of the upper surface of the ceramic tiles. Then, ceramic tiles are hung layer by layer from bottom to top in sequence, so that the pins 2 of the next layer of ceramic tiles are inserted in the lower openings 3 of the upper layer of ceramic tiles to achieve layer-by-layer hanging. When it comes to the uppermost layer of ceramic tiles, the uppermost layer of ceramic tiles are placed in place and the pins 2 of the uppermost layer of ceramic tiles are adjusted so that the pins 2 are inserted in the hanging holes 17 of the upper horizontal keel 16.

[0045] When one or several tiles of the dry-hanging tile curtain wall system are damaged and need to be replaced, first insert I-beams on both sides of the tiles to be replaced to ensure the stability of the curtain wall during the replacement. Using the lifting holes 14 at both ends of the horizontal axis 9, lift and rotate the pin 2 so that the horizontal axis 9 rotates from the shallow groove 10 to the deep groove 11. The pin 2 of the tile and the pin 2 of the lower layer of tiles are converted to disassembly mode, and the tile can be taken out as a whole for replacement. After the replacement is completed, use the lifting holes 14 at both ends of the horizontal axis 9 again to lift and rotate the pin 2 so that the horizontal axis 9 rotates from the deep groove 11 to the shallow groove 10. The pin 2 of the tile and the pin 2 of the lower layer of tiles are converted to hanging mode, and the damaged tile can be replaced conveniently and quickly.

[0046] In summary, the ceramic bricks of the utility model are provided with metal components such as pins, connecting sleeves, horizontal shafts, and baffles to form a vertically connected structure, which brings great convenience to the on-site curtain wall construction and solves the problem of quick and efficient replacement of damaged ceramic bricks in non-hollow ceramic brick curtain walls; therefore, the utility model has broad application prospects in dry-hanging ceramic brick curtain walls.
