Description

Technical Field

[0001] This utility model relates to the field of tile installation, and in particular to a back-bolted tile central hanging structure. Background Technology

[0002] With the continuous development of building exterior wall decoration technology, the back-bolted dry-hanging tile system has been widely used in modern building curtain walls and exterior wall decoration projects due to its high installation efficiency, good structural stability and excellent seismic performance. The system is mainly anchored to the back of the tile by back bolts and then connected to the main structure by metal hangers to form a non-load-bearing exterior enclosure decoration system.

[0003] However, in practical engineering applications, it has been found that existing back-bolted tile hanging systems still have certain technical limitations, especially in the process of multi-tile splicing and continuous laying. Because traditional hanging systems typically use independent unit designs, the hanging points between adjacent tiles lack an effective linkage adjustment mechanism, causing each tile unit to rely on manual positioning and fixing during installation. This method is prone to slight deviations in height or angle between adjacent tile surfaces due to construction errors, structural deformation, or positional tolerances of the hanging system itself. As the laid area increases, these deviations gradually accumulate, eventually resulting in unevenness of the overall wall surface, affecting appearance quality and visual effect. This problem not only reduces the aesthetics of the decorative surface but may also cause edge damage due to stress concentration, and even affect the long-term durability and safety of the system.

It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features.

Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0028] Example 1

[0029] like Figures 1-8 As shown: This embodiment provides a technical solution: a back-bolt type tile combination hanging system for installing tiles 3 on a wall. It includes a square steel column 1 vertically installed on the wall to be hung, upper and lower hanging mechanisms 4 and middle hanging mechanisms 5 assembled on the square steel column 1 by angle steel 2. In the same column of the wall, two sets of upper and lower hanging mechanisms 4 and multiple sets of middle hanging mechanisms 5 are arranged. The two sets of upper and lower hanging mechanisms 4 are located at the top and bottom of the wall, respectively. The multiple sets of upper and lower hanging mechanisms 4 are distributed at equal intervals in the vertical direction between the two sets of upper and lower hanging mechanisms 4. Multiple tiles 3 are installed in the same column of the wall. The multiple tiles 3 in the same column are installed between two middle hanging mechanisms 5 or between the upper and lower hanging mechanisms 4 and the middle hanging mechanism 5 by back bolts 6.

[0030] Working principle: This combined hanging system is used to install tiles 3 on the wall. In use, firstly, several vertically arranged square steel columns 1 are installed on the wall horizontally using expansion bolts. During installation, the distance between two adjacent square steel columns 1 is accurately measured to match the width of the tiles 3. Then, according to the height of the tiles 3, multiple angle steels 2 are welded at equal intervals vertically on the square steel columns 1. Next, the upper and lower hanging mechanisms 4 are fixedly installed on the top and bottom angle steels 2, and the middle hanging mechanisms 5 are fixedly installed on the other angle steels 2. Finally, the tiles 3 are installed from top to bottom between two middle hanging mechanisms 5 or between the upper and lower hanging mechanisms 4 and the middle hanging mechanism 5 to complete the assembly.

[0031] In summary, this combined hanging system mainly includes upper and lower hanging mechanisms 4 and middle hanging mechanism 5. The tile 3 is hung on the wall through the upper and lower hanging mechanisms 4 and the middle hanging mechanism 5. Through the structural design of the upper and lower hanging mechanisms 4 and the middle hanging mechanism 5, the tile 3 is a hanging structure as a whole, which is convenient to install and has higher stability after installation. At the same time, it makes the tile 3 more flat after installation.

[0032] Specifically, such as Figures 1-5 As shown, in order to achieve the hanging installation of tile 3, in this embodiment, the upper and lower hanging mechanism 4 includes a base 40 and a first hanging member 41. The base 40 adopts an L-shaped structure and is detachably installed on the upper part of the angle steel 2 by means of the fixing bolt assembly 7. The first hanging member 41 is snapped on the upper part of the vertical end of the base 40. One side of the first hanging member 41 is fixed to the tile 3 by means of the back bolt 6. Based on this, during installation, the first hanging member 41 is first fixed to the back of the tile 3 by means of the back bolt 6, then the base 40 is installed on the upper part of the angle steel 2 by means of the fixing bolt assembly 7, and then the first hanging member 41 is snapped on the upper part of the vertical end of the base 40.

[0033] Specifically, such as Figures 1-5 As shown, in order to improve the stability of the first hanging member 41 when it is engaged with the base 40, in this embodiment, the upper and lower hanging member mechanism 4 also includes a stabilizing clip 42. The stabilizing clip 42 is engaged above the vertical end of the base 40 and is located between the base 40 and the first hanging member 41. The top of the stabilizing clip 42 is provided with a snap-back clip head 420, which covers the top of the vertical end of the base 40. Based on this, the stabilizing clip 42 forms a fitting structure between the first hanging member 41 and the base 40. Therefore, after the first hanging member 41 is installed, the stability between it and the base 40 is higher, thereby making the overall stability of the tile 3 higher after installation.

[0034] Specifically, such as Figures 1-5As shown, in order to further improve the stability of the engagement of the first hanging member 41, in this embodiment, the top of the stabilizing member 42 is provided with a vertical groove 423 along the vertical direction, and the side of the stabilizing member 42 near the tile 3 is provided with a fastening groove 426. The first hanging member 41 adopts an inverted U-shaped structure. A vertical locking strip 410 is provided below the horizontal end of the first hanging member 41, and a horizontal locking strip 411 is provided on the inner side of the vertical end of the first hanging member 41. The vertical locking strip 410 and the horizontal locking strip 411 are respectively engaged in the vertical groove 423 and the fastening groove 426, and the vertical locking strip 410 and the horizontal locking strip 411 can slide vertically in the vertical groove 423 and the fastening groove 426, respectively. This structural setting makes the engagement effect of the first hanging member 41 and the stabilizing member 42 higher, thus making the engagement stability of the first hanging member 41 higher.

[0035] Specifically, such as Figures 1-5 As shown, in order to position the stabilization clip 42 in a fixed position on the base 40 during installation, in this embodiment, a cavity 421 is provided on the vertical end of the stabilization clip 42 that contacts the base 40. A positioning card 425 is rotatably installed inside the cavity 421 via a torque shaft 424. A positioning slot 400 is also provided on the base 40 at a position corresponding to the cavity 421. The positioning card 425 can be rotated and engaged into the positioning slot 400, so that the stabilization clip 42 can be positioned during installation. Based on the predetermined position on the base 40, when installing the stabilizing clip 42, the positioning card 425 is first vertically accommodated in the cavity 421 by rotation, and then the stabilizing clip 42 is slid from the side. When the position of the cavity 421 coincides with the position of the positioning slot 400, the positioning card 425 is released. Under the elastic force of the torque shaft 424, the positioning card 425 rotates to the horizontal position. At this time, the positioning card 425 is engaged in the positioning slot 400, thus realizing the positioning of the stabilizing clip 42.

[0036] Specifically, such as Figures 1-5 As shown, in order to improve the stability of the base 40 installation, in this embodiment, a gasket 43 is also provided between the base 40 and the angle steel 2, so that the fixing bolt assembly 7 has higher stability when locking the connection between the base 40 and the angle steel 2.

[0037] Specifically, such as Figures 2-5As shown, in this embodiment, in order to adjust the height of the tile 3 and facilitate the adjustment of the spacing between the tiles 3, an adjusting bolt 44 is screwed into the top of the first hanger 41. The top of the stabilizing clip 42 is provided with a top hole 422 at the position of the adjusting bolt 44, and the bottom of the adjusting bolt 44 rests in the top hole 422. Based on this, when the adjusting bolt 44 is rotated, the length of the adjusting bolt 44 below the horizontal end of the first hanger 41 changes, so the overall height of the first hanger 41 changes, thereby realizing the adjustment of the height of the tile 3. In addition, it should be noted that in order to facilitate the installation of the adjusting bolt 44, the top of the vertical end of the base 40 is folded flat with a head 401. By folding the head 401, the width of the top of the vertical end of the base 40 is increased, thus facilitating the adjustment and installation of the adjusting bolt 44.

[0038] Example 2

[0039] like Figure 1 , Figures 6-8 As shown, in order to realize the installation of the central hanging mechanism 5 on the tile 3, based on embodiment 1, in this embodiment, the central hanging mechanism 5 includes a double hanging component 50, a standard alignment hanging component 51, and a second hanging component 52. The front end of the double hanging component 50 is in the shape of a straight line and is detachably installed on the top of the angle steel 2 by the fixing bolt assembly 7. The rear end is in the shape of a C-shape. The standard alignment hanging component 51 is detachably installed on the C-shape structure of the double hanging component 50 by the fixing bolt assembly 7. The second hanging component 52 is fixedly installed on the back of the tile 3 by the back bolt 6 and is snapped onto the standard alignment hanging component 51.

[0040] Example 3

[0041] like Figure 1 , Figures 6-8 As shown, in order to make the tile 3 more flat after installation, based on embodiment 2, in this embodiment, the standard alignment bracket 51 includes a C-shaped part 510 that engages with the inner side of the C-shaped structure of the double bracket 50, an L-shaped part 511 integrally formed on the two horizontal ends of the C-shaped part 510, and a horizontal hanging piece 512 integrally formed on one side of the upper L-shaped part 511. The horizontal hanging piece 512 engages with the top of the double bracket 50.

[0042] The C-shaped part 510 and the double-linked bracket 50, as well as the horizontal bracket 512 and the double-linked bracket 50, are detachably installed via the fixing bolt assembly 7. Based on this, when the second bracket 52 is attached to the standard alignment bracket 51, since the two L-shaped parts 511 are integrated through the C-shaped part 510, when the two L-shaped parts 511 are attached to two adjacent tiles 3, the flatness of the two tiles 3 is consistent, thus making all the tiles 3 more uniform in flatness.

[0043] Specifically, such as Figure 1 , Figures 6-8 As shown, in order to further improve the stability of the tile 3 when installed through the central hanging mechanism 5, in this embodiment, the top of the vertical end of the L-shaped part 511 is provided with a widened part 5110, and the top of the horizontal end of the L-shaped part 511 is provided with a back-hanging part 5111. The second hanging part 52 includes a straight part 520 connected to the tile 3 through a back bolt 6. The top of the straight part 520 is provided with a top hanging part 521, which engages with the widened part 5110. The top of the straight part 520 is provided with a back-hanging groove 522 in the vertical direction, and the back-hanging part 5111 slides and engages in the back-hanging groove 522. Based on this, under the engaging action of the back-hanging groove 522 and the back-hanging part 5111, the engagement stability of the second hanging part 52 and the standard alignment hanging part 51 is better, so the stability of the tile 3 installed through the central hanging mechanism 5 is higher.

[0044] Example 4

[0045] like Figure 9 As shown, to improve the adjustability of the ceramic tile 3, based on the angle steel 2 in the embodiment, in this embodiment, two standard alignment brackets 51 are installed on a central hanging mechanism 5. A second bracket 52 is snapped onto the top of each standard alignment bracket 51. The standard alignment bracket 51 adopts an L-shaped structure. The horizontal ends of the standard alignment bracket 51 are detachably installed above the two horizontal ends of the C-shaped structure of the double bracket 50 through the fixing bolt assembly 7. The second bracket 52 is movably snapped onto the vertical end of the standard alignment bracket 51. The hole on the standard alignment bracket 51 for passing through the fixing bolt assembly 7 is a strip-shaped waist-shaped hole, which allows the standard alignment bracket 51 to move in a direction perpendicular to the wall when the fixing bolt assembly 7 is not locked. This allows the second bracket 52 to move and adjust its position in a direction perpendicular to the wall, facilitating precise height adjustment and control of each ceramic tile 3 installed on the second bracket 52.

[0046] Example 5

[0047] like Figures 1-8 As shown, based on Embodiments 1-4, in this embodiment, the fixing bolt assembly 7 includes a toothed pressure plate 70 and a bolt 71. The toothed pressure plate 70 is movably sleeved on the bolt 71. The upper and lower hanging mechanisms 4 and the middle hanging mechanism 5 are provided with toothed surfaces at the contact positions of the toothed pressure plate 70, which are adapted to the toothed structure at the bottom of the toothed pressure plate 70. When the bolt 71 is tightened to press the toothed pressure plate 70, the toothed structure at the bottom of the toothed pressure plate 70 engages with the toothed surface. Therefore, the locking effect of the fixing bolt assembly 7 is better, and the upper and lower hanging mechanisms 4 and the middle hanging mechanism 5 are less likely to loosen after locking, thereby making the stability of the entire upper and lower hanging mechanisms 4 and the middle hanging mechanism 5 higher.

[0048] Specifically, such as Figures 6-8As shown in this embodiment, in order to adjust the height of the tile 3 and facilitate the adjustment of the spacing between the tiles 3, an adjusting bolt 44 is screwed and inserted into the top hanging part 521. Based on this, when the adjusting bolt 44 is rotated, the length of the adjusting bolt 44 below the top hanging part 521 changes, so the overall height of the second hanging part 52 changes, thereby realizing the adjustment of the height of the tile 3. In addition, it should be noted that the widened part 5110 can better fit the adjusting bolt 44 and facilitate the rotation of the adjusting bolt 44.

[0049] Example 6

[0050] This embodiment discloses a method for dry-hanging ceramic tiles, which is applied to a back-bolted ceramic tile assembly system. The specific steps are as follows:

[0051] Frame arrangement: Install square steel columns 1 on the wall according to the design requirements, and weld angle steel 2 at the predetermined positions on the square steel columns 1;

[0052] Combined hanging component arrangement and installation: The base 40 of the upper and lower hanging component mechanism 4 is fixedly installed on the top and bottom row of angle steel 2 using the fixing bolt assembly 7, and the stabilizing clip 42 is slidably engaged on the vertical end of the base 40. During the engagement of the stabilizing clip 42, the positioning card 425 is first flipped so that it is located in the cavity 421. After the stabilizing clip 42 slides into place, the positioning card 425 is released. At this time, the positioning card 425 rotates to the horizontal under the elastic force of the torque shaft 424, that is, it engages in the positioning slot 400. At this time, the stabilizing clip 42 is positioned. The double hanging component 50 of the middle hanging component mechanism 5 is fixedly installed on the remaining angle steel 2 using the fixing bolt assembly 7. Then, the standard alignment hanging component 51 is engaged on the inner side of the double hanging component 50, and the first hanging component 41 is fixed by the fixing bolt assembly 7.

[0053] Tile 3 installation: Fix the back bolt head to the back of tile 3, and then fix the first hanger 41 or the second hanger 52 to the back of tile 3 according to the preset position;

[0054] Hanging tiles: Using glass suction cups, hang the tiles 3 with the first hanger 41 or the second hanger 52 installed, starting from the bottom and hanging them upwards, so that the first hanger 41 is attached to the stabilizing clip 42 and the second hanger 52 is attached to the standard alignment hanger 51, until all tiles 3 are hung.
