Description

Technical Field

[0001] The present invention belongs to the technical field of tile paving, and more specifically, relates to a small-sized tile paving device and a construction method thereof. Background Art

[0002] When faced with tile laying work scenarios such as a small number of swimming pools, indoor and outdoor floors, indoor and outdoor walls, etc., due to the large differences in the paving areas, irregular shapes, and small sizes of tiles to be laid, the number of tiles to be laid increases, the difficulty of paving increases, and more labor costs are required; at the same time, when laying tiles, the same gap must be left between each interior wall tile, the construction is complicated, time-consuming and labor-intensive, and the paving efficiency is low. Secondly, the gaps between tiles are difficult to control to be consistent in size, and the paving effect is greatly affected by the work skills of the construction workers. If the expected effect is not achieved, rework is required, and time and manpower must be reinvested, further increasing the cost of paving.

[0003] In order to solve some problems existing in the above-mentioned traditional manual laying of tiles, in the prior art, a Chinese patent with the document number CN204126226U discloses a tile laying grid plate, including a transverse fixing rod and a longitudinal fixing rod, the transverse fixing rod and the longitudinal fixing rod are cross-fixed and connected to form a plurality of cross holes, the cross holes correspond to the shape of the tiles to be laid, so that a plurality of tiles to be laid can be set in the plurality of cross holes at the same time. The tile laying grid plate provided by the utility model is simple to make, and the work efficiency can be increased by 9 times compared with the traditional laying method, which solves the problem of complicated construction and low efficiency when laying small-sized interior wall tiles. Secondly, a Chinese patent with document number CN221546147U discloses a small tile paving auxiliary device, which belongs to the field of building construction technology; the small tile paving auxiliary device of the utility model comprises: a grid plate; the grid plate comprises at least two horizontal first flat steels and at least two vertical second flat steels, the first flat steels are welded and connected to the second flat steels, and at least one small tile grid is formed in the middle; the small tile paving auxiliary device can pave multiple small tiles at one time, and the paving efficiency is high; and the tile positioning is convenient, without the need for wires, and the small tile paving auxiliary device only needs to be placed flat on the mortar at the position where paving is required; the small tile paving auxiliary device has a simple structure, is easy to use, and has good practicality.

[0004] Although both of the above patents improve the efficiency of laying small-sized tiles and reduce labor costs by setting up small tile grids, they still do not solve some problems existing in the existing laying devices, such as: (1) the size of the small tile grid is fixed, resulting in poor applicability to tiles of different specifications, reducing the practicality of the device; (2) although a lifting device is added, when used for laying tiles over a larger range, the device is prone to being heavy and inconvenient to carry and transfer; (3) since the device may not be able to meet the requirements of different laying thicknesses, it may have an adverse effect on the final laying effect.
