Description

Technical Field

[0001] This utility model relates to the field of antique brick technology, and in particular to a wear-resistant and sturdy interlocking antique brick. Background Technology

[0002] With the development of the building decoration industry, antique-style bricks are widely used in fields such as floor decoration. Antique-style bricks not only have a unique decorative effect, creating a retro and elegant atmosphere, but also, to a certain extent, satisfy people's needs for architectural aesthetics and cultural heritage.

[0003] Traditional antique-style brick splicing often relies on the rigid fit between the right-angle protrusions at the ends of the bricks and the connecting grooves of adjacent bricks. Under impact loads, the sudden change in stress flow at the right-angle edges (stress concentration factor reaching 2.3-5.0) easily leads to micro-cracks at the root of the protrusions. Especially when the foundation settles unevenly, crack propagation can cause brittle fracture (fracture toughness <1.5 MPa·m¹ / ²), resulting in splicing failure. Furthermore, existing interlocking structures only constrain horizontal displacement, lacking an elastic damping mechanism in the vertical direction. For example, when a vehicle passes over, the vertical movement of the bricks can reach 0.5-1.2 mm (EN 1339 standard test value). Long-term reciprocating friction causes the wear rate at the joints to exceed 0.15 mm / year, accelerating functional degradation. Therefore, we propose a wear-resistant and robust splicing antique-style brick to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the rigid fit between right-angle protrusions and connecting grooves in traditional antique brick splicing, the tendency for micro-cracks to occur at the root of the protrusions due to stress concentration under impact loads, and the lack of vertical constraint leading to increased wear due to vertical jumping of the floor tiles. Therefore, this invention proposes a wear-resistant and robust splicing antique brick.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wear-resistant and sturdy interlocking antique brick includes a first antique brick, a protrusion fixedly connected to one side of the first antique brick, and a first connecting groove corresponding to the protrusion on the side of the first antique brick away from the protrusion.

[0007] The protrusion is provided with a conical rubber strip, which is used to engage with the first connecting groove of the second antique brick. The conical rubber strip is provided with multiple clearance grooves to allow deformation and rebound within the first connecting groove.

[0008] The first antique brick has a second connecting groove on both sides. An H-shaped rubber strip is installed in the second connecting groove. The H-shaped rubber strip is used to engage with the second connecting groove of the antique brick to constrain vertical vibration.

[0009] In one possible design, the top and bottom of the protrusion are provided with slots, and the tapered rubber strip is slidably fitted onto the protrusion and engaged with the two slots.

[0010] In one possible design, the tapered rubber strip is made of TPU / glass fiber composite material.

[0011] In one possible design, the H-shaped rubber strip is made of a polyamide and glass fiber composite material.

[0012] In one possible design, the top of the first antique-style brick is provided with multiple anti-slip raised strips.

[0013] In one possible design, a water channel is provided on the top of the first antique-style brick.

[0014] In one possible design, the top surface of the first antique brick is coated with a wear-resistant layer of polymer composite material.

[0015] In this application, firstly, during splicing, the conical rubber strip on the protrusion on one side of the first antique brick is engaged with the first connecting groove of the second antique brick. Since the conical rubber strip has a clearance groove, it can deform and rebound in the first connecting groove to achieve interference fit and self-locking, effectively avoiding stress concentration, preventing brittle fracture at the root of the protrusion, and enhancing the stability of the splicing structure. At the same time, the H-shaped rubber strip on the first antique brick is engaged with the second connecting groove of the adjacent third antique brick. This structure can effectively restrain vertical vibration and impact, reduce vertical jumping of the floor tiles, and reduce joint wear.

[0016] During use, when pedestrians pass by, the anti-slip ridges on the top of the first antique brick increase friction and play an anti-slip role, ensuring pedestrian safety. In case of water accumulation, the drainage channel can drain water quickly, preventing water accumulation from having an adverse effect on the antique brick. The wear-resistant layer of polymer composite material sprayed on the top can effectively resist wear caused by daily friction and extend the service life of the antique brick.

[0017] Beneficial effects: In this utility model, the wear-resistant and sturdy spliced ​​antique brick, by setting a conical rubber strip on the protrusion, uses its interference fit with the first connecting groove to achieve self-locking, so that the first antique brick and the second antique brick are firmly connected. When subjected to external force, the conical rubber strip can deform and rebound, effectively relieving stress concentration and avoiding brittle fracture at the root of the protrusion due to uneven foundation settlement, etc., which greatly improves the stability and reliability of the splicing structure and reduces the risk of splicing failure.

[0018] In this utility model, a wear-resistant and sturdy interlocking antique brick is provided. The adjacent antique bricks are clamped by H-shaped rubber strips, which solves the problem of insufficient vertical constraint. When vehicles or heavy objects pass by and generate vertical vibration and impact, the H-shaped rubber strips can play a buffering and restraining role, reduce the vertical jump of the floor tiles, reduce the wear of the joints caused by long-term vertical movement, extend the service life of the antique bricks, and ensure the use effect.

[0019] In this invention, a wear-resistant and sturdy interlocking antique-style brick is provided with anti-slip raised strips, which increases friction and improves safety during use. At the same time, the top is sprayed with a polymer composite wear-resistant layer, which enhances the wear resistance of the antique-style brick surface, reduces wear during daily use, and further extends its service life.

[0020] In this invention, the interference fit between the conical rubber strip on the protrusion and the first connecting groove provides self-locking, which alleviates stress concentration, prevents brittle fracture of the protrusion, and improves splicing stability. At the same time, the H-shaped rubber strip connection buffers vertical vibration impact, reduces vertical jump and joint wear, and extends service life. Furthermore, the anti-slip protrusion increases friction to ensure safety, and the wear-resistant coating reduces wear, further extending service life. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1: Refer to Figure 1-4 An antique-style brick includes a first antique-style brick 1, which serves as the basic unit. A protrusion 2 is fixedly connected to one side of the first antique-style brick 1, and a first connecting groove 3 matching the protrusion 2 is formed on the other side. A tapered rubber strip 4, made of TPU / glass fiber composite material, is provided on the protrusion 2, combining elasticity and strength. When the first antique-style brick 1 and a second antique-style brick 9 are joined, the protrusion 2 inserts into the first connecting groove 3 of the second antique-style brick 9. The tapered rubber strip 4, due to the multiple clearance grooves, can deform and rebound within the grooves, forming an interference fit self-locking structure. This structure effectively alleviates stress concentration, prevents brittle fracture at the root of the protrusion due to external forces such as foundation settlement, significantly improves the stability of the spliced ​​structure, and reduces the risk of splicing failure.

[0028] The first antique-style brick 1 has second connecting grooves 5 on both sides, and H-shaped rubber strips 6 are fitted into the grooves. These rubber strips are made of a high-performance engineering material composed of polyamide and glass fiber, possessing excellent cushioning properties. When adjacent antique-style bricks 10 are fitted into the H-shaped rubber strips 6 via the second connecting grooves 5, vertical vibration and impact can be effectively restrained, reducing vertical movement of the bricks, decreasing wear on the joints caused by long-term friction, and extending the service life of the antique-style bricks.

[0029] The tapered rubber strip 4 is installed and functions by having slots at the top and bottom of the protrusion 2. The tapered rubber strip 4 slides onto the surface of the protrusion 2 through these slots. During splicing, the rubber strip is compressed and deformed, providing space for deformation in the slots, allowing the rubber strip to fit tightly against the inner wall of the first connecting groove 3, achieving self-locking. The use of TPU / glass fiber composite material ensures both the elastic deformation capability of the rubber strip and enhances its fatigue strength, ensuring the reliability of the spliced ​​structure during long-term use.

[0030] The H-shaped rubber strip 6 has an "H"-shaped cross-section, with its two flanges respectively engaging the second connecting groove 5 of the adjacent antique-style bricks. The composite material of polyamide and glass fiber allows it to absorb impact energy through elastic deformation under vertical loads, effectively suppressing the vertical displacement of the floor tiles. For example, when vehicles drive over it or heavy objects are placed on it, the H-shaped rubber strip can buffer vibrations, preventing damage to the joints due to severe impacts and ensuring the stability and performance of the splicing structure.

[0031] This application can be used in the field of antique brick technology, or in other fields applicable to this application.

[0032] Example 2: Reference Figure 1-3Based on Example 1, an improvement is made: a wear-resistant and robust interlocking antique-style brick, applied to the field of antique bricks. The first antique-style brick 1 features multiple anti-slip raised strips 8 on its top, increasing surface roughness to enhance friction and prevent pedestrians from slipping, significantly improving safety, especially in humid environments. A water-guiding channel 7 on the top guides accumulated water quickly to the drainage system, preventing water from seeping into the brick body and reducing the risk of freeze-thaw damage. Furthermore, a polymer composite wear-resistant layer is sprayed onto the top of the brick. This coating bonds tightly to the brick surface, resisting daily friction and scratches. Tests show that the wear-resistant layer can extend the service life of the antique-style brick by more than 30%.

[0033] During splicing, first align the protrusion 2 of the first antique brick 1 with the first connecting groove 3 of the second antique brick 9, apply appropriate pressure to make the conical rubber strip 4 snap into the groove, and complete the longitudinal splicing; then embed the H-shaped rubber strip 6 into the second connecting groove 5 of the first antique brick 1, and then align the second connecting groove 5 of the adjacent antique brick 10 with the H-shaped rubber strip 6 to snap it in, and complete the transverse splicing.

[0034] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
