Description

Technical Field

[0001] This utility model belongs to the field of marble paving, and in particular relates to a positioning and leveling device for improving the quality of marble paving. Background Technology

[0002] The quality of marble paving used in public areas directly impacts the developer's satisfaction with the overall interior decoration project.

[0003] Marble paving is prone to common quality problems such as hollow spots, uneven joints, cracks, damage, and color differences. In severe cases, it can lead to detachment. These quality problems pose safety hazards in public areas with high foot traffic.

[0004] During the wall tile installation process, the workers did not use plastic cross clips to properly leave gaps between adjacent marble pieces, resulting in twisting and deformation. This caused the gaps to be of varying widths, making it impossible to ensure that a 2mm expansion joint was left between adjacent marble pieces as required.

[0005] If expansion joints are not properly placed, the expansion of subsequent wall tiles due to heat or moisture can cause stress between adjacent marble tiles, leading to unevenness, warping, and hollowing. Utility Model Content

[0006] One object of this invention is to provide a positioning and leveling device for improving the quality of marble paving, and to provide at least the advantages described below.

[0007] Another objective of this invention is to provide a positioning and leveling device for improving the quality of marble paving, which precisely leaves a 2mm expansion joint to improve the quality of marble paving.

[0008] The technical solution of this utility model is as follows:

[0009] A positioning and leveling device for improving the quality of marble paving, comprising:

[0010] The positioning pin, from top to bottom, includes a gripping part at the top, a threaded section in the middle, a positioning section at the bottom, and a limiting rod at the bottom.

[0011] And an adjusting ring, which is threadedly fitted onto the outer periphery of the threaded section;

[0012] in;

[0013] The limiting rod is horizontally positioned and distributed in an inverted T-shape with the positioning segment;

[0014] The diameter of the limiting rod is smaller than the width of the pre-reserved gap in the marble.

[0015] The diameter of the positioning segment matches the width of the pre-reserved gap in the marble.

[0016] The lower surface of the adjusting ring is horizontal and its diameter is greater than the width of the pre-reserved gap in the marble.

[0017] Preferably, the positioning and leveling device for improving the quality of marble paving further includes:

[0018] support;

[0019] A first linear actuator is mounted on the bracket and located directly above the pre-reserved gap in the marble, with the output end of the first linear actuator positioned vertically downwards;

[0020] A rotary stepper motor is disposed at the output end of the first linear driver, and the output end of the rotary stepper motor is disposed vertically downward;

[0021] And a holding part, which is disposed at the output end of the rotary stepper motor and engaged with the holding part.

[0025] A pair of finding plates are disposed at the output end of the third linear drive, and the lower surface of the finding plates is in abutting contact with the upper surface of the marble.

[0026] Preferably, in the aforementioned positioning and leveling device for improving the quality of marble paving,

[0027] The bottom of the outer side of the adjusting ring extends outward to form a square connecting plate;

[0028] The bottom of the inner side of the flat plate is recessed to overlap with the square connecting plate.

[0029] This utility model has the following beneficial effects:

[0030] During the installation process, a 2mm expansion joint must be precisely left, and the joint width must not be deformed by external force, must be uniform, and must not leave any debris in the gaps.

[0031] It effectively fixes two adjacent stones to prevent movement, ensuring that the stones remain on the same horizontal plane during the laying process and effectively controlling the height difference between the joints of adjacent stones.
