Description

Technical Field

[0001] This utility model relates to the field of floor construction, and in particular to a step structure based on groove tenon and mortise fixing. Background Technology

[0002] With the continuous development of the construction and decoration industry, wood flooring has been widely used in various interior decoration projects due to its aesthetic appeal, comfort, and natural appearance. When laying wood flooring on steps, the protection and decoration of its edges are crucial. Traditional wood flooring corner protectors for steps have the following problems: (1) Insecure fixing: Common glue-based methods are prone to corner protectors falling off due to glue aging, humid environments, etc.; screw fixing may loosen under the thermal expansion and contraction of the wood flooring, affecting the fixing effect of the corner protectors. (2) Poor protection effect: The edges of the wooden floor are easily trampled by pedestrians, bumped when moving items, and scratched by daily cleaning tools, which leads to wear and damage to the edges of the wooden floor, thus affecting the service life and aesthetics of the entire wooden floor. Traditional corner protectors often cannot provide effective protection. Therefore, how to solve the corner problems of the above steps has become an urgent problem for those skilled in the art. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a step structure based on groove tenon and mortise fixing.

[0004] This utility model is achieved through the following technical solution: A step structure based on groove tenon and tenon fixing includes a horizontal step plate, a vertical kick plate and a pressure strip. The pressure strip has a mirror F-shaped cross-section and includes an integrally formed flat plate and a grooved portion. The flat plate presses down on the step plate, and the grooved portion is tenon and tenon fixedly connected to the upper part of the kick plate.

[0005] As can be seen, the above technical solution effectively solves the problem of unreliable fixing by replacing traditional glue or screw fixing with mortise and tenon joints; the mirror-shaped F-shaped strip allows the flat part to effectively press down on the step board, and the groove part wraps around the upper part of the kick panel to form an overall cover, enhancing the protection of the step edge and effectively preventing wear caused by stepping, bumping and scratching, thus extending the service life of the wood flooring; moreover, the one-piece molded strip structure can effectively simplify the installation process and improve construction efficiency.

[0006] According to the above technical solution, preferably, the lower edge of the step plate is provided with a strip-shaped protrusion, and the upper end of the kick plate is provided with a strip-shaped groove that matches the strip-shaped protrusion. The strip-shaped protrusion is inserted into the strip-shaped groove. The groove includes an inner insert plate and an outer retaining plate arranged in parallel. The inner insert plate is inserted into the strip-shaped groove, and the two sides of the inner insert plate abut against the side of the strip-shaped protrusion and the inner wall of the strip-shaped groove, respectively. The inner side of the outer retaining plate abuts against the outer side of the kick plate.

[0007] As can be seen, in the above technical solution, by adding the plug-in connection between the step plate and the kick plate, as well as the inner insert plate and outer clamping plate of the groove, this structure can effectively enhance the mechanical connection strength between the step plate, the kick plate and the pressure strip, forming a multi-layered fixed connection relationship. After the inner insert plate is inserted into the strip groove, its two sides abut against the inner wall of the strip protrusion and the strip groove respectively, and the outer clamping plate clamps the kick plate from the outside, effectively preventing the relative displacement between the components and effectively improving the problem of easy loosening in the traditional fixing method; and it can improve the impact resistance of the step edge, providing better protection.

[0008] According to the above technical solution, preferably, the strip-shaped slot is provided with multiple sets of locking components spaced apart, the locking components include a spring unit and a limiting block, and the inner insert plate is provided with positioning holes adapted to the limiting block.

[0009] As can be seen, in the above technical solution, an additional mechanical locking mechanism is provided by the locking component. When the inner insert plate is inserted into the strip slot, the limiting block is locked into the positioning hole under the action of the spring, forming a positive lock to prevent the inner insert plate from accidentally coming out. This design is particularly suitable for the thermal expansion and contraction characteristics of wood flooring.

[0010] According to the above technical solution, preferably, the side of the strip-shaped protrusion is provided with a first friction surface, and the side of the inner insert plate is provided with a second friction surface that is adapted to the first friction surface.

[0011] As can be seen, in the above technical solution, the friction between the strip protrusion and the inner plate can be effectively increased by the first friction surface and the second friction surface. This can effectively suppress the slight slippage caused by vibration or stepping during use, and enhance the tightness and stability of the connection between the components.

[0012] According to the above technical solution, preferably, the stepped plate is provided with a strip-shaped limiting groove, and the inner side of the flat plate is provided with a strip-shaped limiting strip that matches the strip-shaped limiting groove.

[0013] According to the above technical solution, preferably, the outer side of the kick panel is provided with a strip-shaped limiting groove, and the inner side of the outer card plate is provided with a strip-shaped limiting strip that matches the strip-shaped limiting groove.

[0014] According to the above technical solution, preferably, the cross-section of the strip-shaped limiting groove is a semi-heart-shaped cross-section that can prevent detachment.

[0015] As can be seen, in the above technical solution, when the limiting groove of the half-heart cross section is combined with the limiting strip, a barb-like anti-loosening structure is formed. Once the limiting strip is inserted, it is stuck in the limiting groove and cannot be pulled out in the opposite direction, thus avoiding the limiting strip from coming off due to accidental collision or long-term use, and significantly improving the anti-loosening performance of the limiting structure.

[0016] The beneficial effects of this utility model are: (1) This patent replaces the traditional glue or screw fixing with mortise and tenon fixing, effectively solving the problem of unreliable fixing; (2) The mirror F-shaped pressure strip in this patent enables the flat part to effectively press down the step board, and the groove part wraps around the upper part of the kick panel to form an overall coverage, which enhances the protection effect of the step edge, effectively prevents wear caused by stepping, bumping and scratching, and extends the service life of the wood floor. (3) The integral molding strip structure in this patent can effectively simplify the installation process and improve construction efficiency. Attached Figure Description

The cross-section of the pressure strip 3 is a mirror F-shape. The pressure strip 3 includes an integrally formed flat plate part 4 and a groove part 5. The flat plate part 4 presses down on the step plate 1, and the groove part 5 is fixedly connected to the upper part of the kick plate 2 with tenon and tenon. The lower edge of the step plate 1 is provided with a strip-shaped protrusion 6, and the upper end of the kick plate 2 is provided with a strip-shaped groove 7 that matches the strip-shaped protrusion 6. The strip-shaped protrusion 6 and the strip-shaped groove 7 are inserted and connected. The groove 5 includes an inner insert plate 8 and an outer clamping plate 9 arranged in parallel. The inner insert plate 8 is inserted into the strip-shaped groove 7, and the two sides of the inner insert plate 8 abut against the side of the strip-shaped protrusion 6 and the inner wall of the strip-shaped groove 7, respectively. The inner side of the outer clamping plate 9 abuts against the outer side of the kick plate 2. This structure can effectively enhance the mechanical connection strength between the step plate 1, the kick plate 2 and the pressure strip 3, forming a multi-layered fixed connection relationship. After the inner insert plate 8 is inserted into the strip-shaped groove 7, the two sides abut against the inner wall of the strip-shaped protrusion 6 and the strip-shaped groove 7, respectively. The outer clamping plate 9 clamps the kick plate 2 from the outside, effectively preventing relative displacement between the components and effectively improving the problem of easy loosening in traditional fixing methods. In addition, it can improve the impact resistance of the step edge and provide better protection. Furthermore, the strip slot 7 is provided with multiple sets of locking components 10 spaced apart. The locking component 10 includes a spring unit 11 and a limiting block 12. The inner insert plate 8 is provided with a positioning hole 17 that matches the limiting block 12.
