Description

Technical Field

[0001] The utility model relates to the technical field of stair treads, in particular to a mortise and tenon type hard stair tread. Background Art

[0002] At present, the conventional process of stair stone finishing commonly seen on the market adopts traditional cement-yellow sand dry mix slurry as the base layer and is installed with cement slurry or adhesive. The yellow sand cement mortar used in the installation process needs to be mixed on site, which requires sufficient storage yard and mixing site, which is easy to cause secondary pollution and affect other materials and finished products. In addition, the ratio of yellow sand and cement depends entirely on the personal experience of the operator. Sometimes the low solidification strength leads to hollowing phenomenon and cracking of the finishing. In addition, some finishing materials with higher transparency and lower density have more alkali backflow when using this method.

[0003] Therefore, it is necessary to provide a mortise and tenon type hard stair tread to solve the above technical problems. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the existing technology, the utility model provides a mortise and tenon type hard stair tread with a horizontal base plate and a vertical base plate connected by a mortise and tenon structure, which reduces the tedious steps in the construction process of the stair treads and reduces the construction difficulty. At the same time, it also greatly reduces the labor intensity of the construction workers, saves construction costs, and brings convenience to users.

[0005] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0006] A mortise-and-tenon rigid stair tread comprises a horizontal base plate, vertical base plates, a horizontal veneer, and vertical veneer panels. The horizontal and vertical base plates are constructed with an inorganic stone or artificial stone base, while the horizontal and vertical veneer panels are constructed with stone, rock slabs, or ceramic tiles. The vertical base plates have grooves on opposite sides, and the grooves are symmetrical. The horizontal base plates have protrusions on opposite sides, and the protrusions are symmetrical and mate with the grooves. The horizontal and vertical base plates are installed from top to bottom, while the vertical veneer panels are installed on one side of the vertical base plates. The horizontal veneer panels are L-shaped and are mounted on the horizontal base plates, partially locking onto one side of the vertical veneer panels. The veneer panels are installed from bottom to top.

[0007] Preferably, the horizontal base plate and the vertical base plate are both bonded to the stair treads via AB adhesive layers, and the horizontal decorative panels and the vertical decorative panels are both bonded to the horizontal base plate and the vertical base plate via structural adhesive layers.

[0008] Preferably, the horizontal base plate and the vertical base plate are both provided with a plurality of through holes arranged side by side, and steel bars with matching diameters can be inserted into the through holes.

[0009] Preferably, an adjustment substrate is added between the cut horizontal substrates or vertical substrates, and the adjustment substrate is also provided with through holes of the same number and size as the horizontal substrates or vertical substrates. Multiple steel bars penetrate the horizontal substrates or vertical substrates and the through holes on the adjustment substrate, so that the horizontal substrates or vertical substrates and the adjustment substrate become one.

[0010] Preferably, the adjustment substrate can be obtained by cutting off the protrusions or grooves at both ends of the horizontal substrate or the vertical substrate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:
