Description

Technical Field

[0001] This utility model relates to the field of building decoration construction technology, and in particular to a tool for controlling the quality of tile installation joints. Background Technology

[0002] During tile installation, strict treatment of the joints is necessary to ensure construction quality and aesthetics. If the joints are too large, external factors such as moisture will quickly penetrate, causing corrosion of the internal adhesive material and leading to tile detachment. If the joints are too small, the adhesive material will not be able to penetrate, failing to achieve the purpose of adhesion and also greatly affecting the subsequent grouting process.

[0003] Existing technologies typically use retaining strips to control the joints between tiles. A retaining strip of the same size is embedded at each end of the joint, ensuring consistent joint width. However, this method has several drawbacks. First, its application is limited; it can only be used when two tiles are on the same plane. Retaining strips cannot be embedded at corners or other turning points. Furthermore, since the retaining strip needs to be embedded within the joint, it cannot be used when other wiring is being installed within the joint, such as a network cable. Second, the joint width is limited to the strip's thickness and cannot be adjusted. One type of retaining strip is only suitable for one type of joint and relies heavily on the installer's experience. If the retaining strip is not properly clamped between the two tiles or is clamped too tightly, causing deformation, consistent joint width cannot be guaranteed. Finally, the retaining strip cannot be recycled; the embedded portion needs to be cut off, and a large number of strips are consumed during each installation.

[0004] Therefore, this utility model develops a tool for controlling the quality of tile installation joints to solve the above-mentioned technical problems. Utility Model Content

[0048] Specifically, a first suction cup 2 is installed on the first main rod 1 to fix it to the tile; a second suction cup 7 is installed on the second main rod 6 to fix it to the tile; the first main rod 1 and the second main rod 6 are fixed to the tile by suction cups, which is convenient to disassemble, can be reused, and does not occupy the space in the splice seam 11 when fixed, so that the wiring can run normally in the splice seam 11.

[0049] As a specific implementation method of this embodiment, the specific method for using the tile installation joint quality control tool of this application is as follows:

[0050] The worker first pastes the first tile into the desired position, and then pastes the second tile into the desired position. Using the tile installation joint quality control tool of this application, the position of the second tile is adjusted with the first tile as a reference, thereby adjusting the size of the splicing joint 11 between the second tile and the first tile. When using the tile installation joint quality control tool of this application, the axial direction of the first main rod 1 and the axial direction of the second main rod 6 are both perpendicular to the splicing joint 11.

[0051] As shown in the figure, when two tiles are pasted on the same plane, firstly, align the scale on the first connecting rod 3 with the edge of the first tile. For example, the scale on the first scale line corresponding to the edge of the first tile is 'a'. Then, fix the first main rod 1 and the first tile. Fix the second main rod 6 and the second tile. At this time, the scale on the first connecting rod 3 corresponding to the end face of the first adjusting head 4 near the first main rod 1 is 'b', the scale on the second connecting rod 8 corresponding to the edge of the second tile is 'c', and the scale on the second connecting rod 8 corresponding to the end face of the second adjusting head 9 near the end face of the second main rod 6 is 'd'. The first adjusting head 4 and the second adjusting head 9 move along their respective... The length along the axis is e; then, the size of the joint 11 between the two tiles is (ab) + e + (cd). The size of the joint 11 can be adjusted according to actual needs. Specifically, rotate the first connecting rod 3, move the first adjusting head 4, change the scale number b, and thus adjust the value of (ab); rotate the second connecting rod 8, move the second tile back and forth, change the scale number d, and thus adjust the value of (cd); during the adjustment process, always keep the first tile still, and adjust the position of the second tile based on the first tile; during the adjustment process, the first tile can be pressed down to ensure that the first tile does not move.

[0052] If the dimensions of the seam 11 are required to be smaller than the length e of the first adjusting head 4 and the second adjusting head 9, the method of using this device is as follows:

[0053] Align the scale on the first adjusting head 4 with the edge of the first tile, for example, the scale corresponding to the edge of the first tile is f; then fix the first main rod 1 and the first tile together, and fix the second main rod 6 and the second tile together; then rotate the second connecting rod 8 so that the edge of the second tile is aligned with the scale on the second adjusting head 9, the scale being g; at this time, the size of the splice seam 11 is f+g; rotating the first connecting rod 3 can adjust the size of f, and rotating the second connecting rod 8 can adjust the size of g, which can be adjusted by the staff according to actual needs.

[0054] Depending on the actual situation, this application can also have various measurement methods. For example, the edge of the first tile is aligned with the scale number m on the first adjusting head 4, and then the first main rod 1 and the second main rod 6 are fixed on the first tile and the second tile respectively; at this time, the edge of the second tile is aligned with the second scale line of the second connecting rod 8, and the scale number is n; the scale number on the second scale line corresponding to the end face of the second adjusting head 9 near the second tile is o; at this time, the size of the splice seam 11 is a + 0.5e + (cd); then the first connecting rod 3 or the second connecting rod 8 is rotated to move the second tile, and d changes, thereby adjusting the size of the splice seam 11; other measurement methods are not listed one by one in this embodiment.

[0055] The tile installation joint quality control tool in this application can also control the size of the joint 11 at the external corner, ensuring that the joint 11 at the external corner is the same size; the specific usage method is as follows:

[0056] When two tiles are at an external corner, first adhere the tiles to the wall. First, align the scale on the first connecting rod 3 with the edge of the first tile at the joint 11. For example, the scale corresponding to the edge of the first tile is h. Then, fix the first main rod 1 and the first tile. Rotate the first connecting rod 3, causing the first adjusting head 4 to move the second adjusting head 9 and the second main rod 6 to a suitable position, making the surfaces of the second main rod 6 and the second tile parallel. Then, fix the second main rod 6 and the second tile. At this point, the scale corresponding to the edge of the second tile is i. Next, fine-tune the joint 11. Rotate the first connecting rod 3, causing the second adjusting head 9 to move along the axis of the first connecting rod 3 towards the first tile. As the second adjusting head 9 moves, it rotates around the axis, causing the second tile... The brick is rotated and pressed against one side of the wall, narrowing the joint 11 between the two tiles. At this time, the scale corresponding to the end face of the first adjusting head 4 near the first main rod 1 is g. The second connecting rod 8 is rotated to pull the second tile towards the first tile to a suitable distance, further narrowing the joint 11. At this time, the scale corresponding to the end face of the second adjusting head 9 near the second main rod 6 is k. The joint 11 at the corner of the two tiles is adjusted. When pasting the next pair of tiles at the corner, the above operation is repeated to ensure that the scale corresponding to the edge of the first tile is h, the scale corresponding to the edge of the second tile is i, the scale corresponding to the face of the first adjusting head 4 near the first main rod 1 is g, and the scale corresponding to the end face of the second adjusting head 9 near the second main rod 6 is k. This ensures that all joints 11 at the corner are the same size.

[0057] As a specific implementation of this embodiment, depending on the size of the tile, the position of the splice seam 11 between two tiles can be adjusted using multiple tile installation seam quality control tools of this application. Multiple tile installation seam quality control tools can fix the tiles more firmly and also control the size of the entire splice seam 11 more precisely.

[0058] As a specific implementation of this embodiment, during the tile installation process, the first tile is first placed to the standard position, then the second tile is installed, and the tile installation joint quality control tool of this application is fixedly installed on the two tiles respectively. Then, the splicing joint 11 between the two tiles is adjusted according to the above operation; then the third tile is installed, and the tile installation joint quality control tool of this application is fixedly installed on the two tiles respectively. Using the second tile as a reference, the splicing joint 11 between the second tile and the third tile is adjusted; and so on, the remaining tiles are installed in sequence, and the splicing joint 11 between adjacent tiles is adjusted using the tile whose splicing joint 11 has been adjusted as a reference.

[0059] Specifically, it also includes at least a third main rod and a third limiting mechanism; the third main rod is detachably fixed to the tile; a third adjusting head assembly is slidably mounted on the third main rod, and the extension / retraction amount of the third adjusting head assembly is positioned by the third limiting mechanism; the third adjusting head assembly and the first adjusting head assembly or the second adjusting head assembly are rotatably engaged; the moving direction of the third adjusting head assembly is perpendicular to the direction of the tile joint 11, and it cooperates with the first adjusting head assembly and the second adjusting head assembly to control the size of the tile joint 11; as a specific implementation of this embodiment, the third main rod has the same structure as the first main rod 1, and the same fixing method as the tile; the third limiting mechanism has the same structure as the first limiting mechanism; the third adjusting head assembly has the same structure as the first adjusting head assembly; by adding a third main rod, the fixing strength between the tile installation joint quality control tool and the tile can be further increased, and the tile installation joint quality control tool and the tile will not fall off without external force.

[0060] As a specific implementation of this embodiment, the tile installation joint quality control tool can be equipped with multiple main rods as needed, and each main rod is fixedly connected with a connecting rod and an adjustment head assembly.

[0061] As a specific implementation of this embodiment, after a period of time, once the tiles are firmly bonded to the wall, the tile installation joint quality control tool can be removed from the tiles for recycling; the tiles are connected to the main rod via suction cups, and the suction cups can be directly pulled off the tiles.
