Description

Technical Field

[0001] This utility model relates to the field of decorative panel leveling, and more specifically, to a three-in-one tool for leveling, plumb-finding, and positioning decorative panel steps. Background Technology

[0002] Currently, materials such as ceramic tiles, marble, and granite are widely used for veneer installation on steps or stair treads due to their high hardness, rich colors, good workability, and ease of cleaning. However, in the actual installation of veneer panels, precise control of the levelness of the treads, strict control of the verticality of the uprights, and precise control of the 90° positioning between the treads and the uprights are crucial.

[0003] In existing technologies, workers often rely on spirit levels, water level instruments, or simple angle iron tools for measurement and positioning, or even operate solely by visual inspection. This often leads to a situation where adjusting the levelness of the step treads affects the verticality of the uprights, or vice versa, resulting in a situation where one aspect is addressed at the expense of another. Therefore, developing a construction tool that integrates the functions of "leveling, plumbness assessment, and positioning" has become an urgent need to improve the accuracy and efficiency of decorative panel step paving. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a three-in-one tool for leveling, plumb-finding, and positioning decorative panel steps. This three-in-one tool enables precise control of the level of the step treads, strict control of the verticality of the uprights, and precise 90° positioning between the step treads and the uprights. This not only improves positioning accuracy and reduces the skill requirements of operators, but also greatly improves construction efficiency and promotes the development of the entire industry. Therefore, this utility model has broad application prospects.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A three-in-one tool for leveling, plumb, and positioning decorative panel steps, characterized in that it comprises: two sets of bent vertical short rods, two sets of horizontal long rods, a middle long rod, a leveling bubble meter, and an adjustment knob; two sets of bent vertical short rods are arranged in parallel, two sets of horizontal long rods are arranged in parallel between the two bent vertical short rods, and the middle long rod is arranged between the two horizontal long rods; both ends of the horizontal long rods and the middle long rod are perpendicularly connected to the two bent vertical short rods on both sides; the leveling bubble meter is horizontally fixed to the upper surface of the middle long rod; and the adjustment knob is located on the bent vertical short rod.

[0007] The bent vertical short rod includes a straight short rod, an upper bent short rod, and a lower bent short rod. The upper bent short rod is connected to one end of the straight short rod at a 90° angle; the lower bent short rod is connected to the other end of the straight short rod at a 90° angle; the upper bent short rod and the lower bent short rod are set in opposite directions, and the connection points of the upper bent short rod, the lower bent short rod, and the straight short rod are all provided with arc transitions.

[0008] The lower bent short rod of the bent vertical rod has a threaded through hole with a matching adjustment knob.

[0009] A vertical short rod is provided between the middle long rod and the two side horizontal long rods. The vertical short rod is located at the midpoint of the middle long rod, and its two ends are perpendicularly connected to the horizontal long rod and the middle long rod, respectively.

[0010] The adjustment knob is a butterfly bolt, which is fixed and controlled by moving the threaded through hole at the lower bent short rod.

[0011] The bent vertical short rod, the horizontal long rod, the middle long rod, and the vertical short rod are all made of square steel tubing; the bent vertical short rod is connected to the horizontal long rod by welding; the bent vertical short rod is connected to the middle long rod by welding; the horizontal long rod is connected to the vertical short rod by welding; and the middle long rod is connected to the vertical short rod by welding.

[0012] In the horizontal bubble meter, the first bubble meter is set parallel to the long rod in the middle, and the second bubble meter is set parallel to the bent vertical short rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model device adopts a standard square steel tube welded structure, featuring convenient material sourcing, simple processing, good overall rigidity, and resistance to deformation. Its reasonable structural design is applicable to the installation of decorative panels for treads of different widths, and suitable for various types of ceramic tiles, marble, granite, and other decorative panels. It is highly practical and easy to promote. The level bubble meter is set in two directions, one parallel to the long rod in the middle and the other parallel to the bent vertical short rod, making the readings intuitive and easy to understand. The butterfly-shaped adjustment knob design facilitates the installation needs of decorative panels of different thicknesses, and workers can easily fix them even while wearing gloves. The application of this device not only effectively ensures the levelness and flatness of the treads, the strict verticality of the uprights, and the precise uniformity of the 90° positioning between the treads and uprights, but also significantly improves the overall construction quality and aesthetics of the stairs or steps. The device is simple to operate, greatly reducing the need for workers' personal experience and skill level. Precise control reduces material waste, shortens construction time, and lowers overall construction costs. Attached Figure Description
