Description

Technical Field

[0001] This utility model relates to the field of stair tread protection technology, and in particular to an active stair tread corner protection device. Background Technology

[0002] Staircase corner protectors (also called staircase corner guards or staircase corner protection) are a technique used to protect the outer edges of staircase treads. Due to frequent use, the outer corners of staircases are easily subjected to impacts or friction, leading to wear, cracks, or damage. To enhance staircase durability, ensure walking safety, and reduce maintenance costs, corner protectors are becoming increasingly common in staircase design.

[0003] Currently, the traditional method is often used to embed round steel into the plaster layer during the construction of external corner protection for stair treads, thus protecting the corners. However, over time, the round steel embedded at the ends of the finished stair treads is easily disturbed and loosened due to repeated foot traffic, resulting in chipped edges and corners at the front of the treads, or even complete separation. This seriously affects the overall aesthetics and functionality, and cannot meet the requirements of modern building development. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an active stair tread corner protection device.

[0005] This utility model is achieved using the following technical solution: an active stair tread corner protection device, comprising a concrete tread, wherein a tread plaster layer is fixedly connected to the upper end of the concrete tread, and a protective block is further connected to the upper end of the concrete tread. A ceramic tile strip is provided at the upper end of the tread plaster layer, auxiliary grooves are provided on both sides of the ceramic tile strip, a drainage groove is provided at the upper end of the ceramic tile strip, and a connecting groove is provided at the lower end of the ceramic tile strip.

[0006] The above technical solution utilizes the reaction force at the end of the porcelain brick strips and the hard porcelain brick strips to resist and offset the pressure exerted by daily pedestrian traffic on the steps, effectively preventing disturbance at the ends of the stair treads and avoiding local chipping or breakage.

[0007] As a further improvement to the above solution, the surface of the protective block is engaged with the inner wall of the auxiliary groove, and the tread surface layer is fixedly connected to the ceramic tile strip by tile adhesive.

[0008] The above technical solution, which uses protective blocks to block the porcelain tile strips, makes it easier to install and position the porcelain tile strips, prevents the porcelain tile strips from shifting during tiling operations, and makes the device more convenient to use.

[0009] As a further improvement to the above solution, the inner wall of the connecting groove is in contact with the surface of the step surface layer.

[0010] As a further improvement to the above solution, the ceramic tile strip is made of an acid and alkali resistant material.

[0011] The above technical solutions can effectively extend the service life of ceramic brick strips, prevent brick surface damage or fading due to chemical corrosion, and improve the overall practicality of the device.

[0012] As a further improvement to the above solution, the surface of the step surface layer is in contact with the side end of the protective block.

[0013] As a further improvement to the above solution, the drainage groove is located at the upper end of the auxiliary slot.

[0014] The above technical solution can help drain water to both ends when sewage accumulates on the top of the porcelain brick strip, thus improving the overall practicality of the device.

[0015] As a further improvement to the above solution, the protective blocks are located on both sides of the ceramic brick strip.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes porcelain tile strips attached to the front end of the stair tread surface layer. The hard porcelain tile strips resist and counteract the pressure exerted by daily foot traffic, effectively preventing disturbance at the ends of the stair treads and avoiding chipped edges or corners. This enhances the overall performance of the staircase, avoids additional maintenance costs due to broken edges, and provides added value by using porcelain tiles as the tread surface. It offers significant economic and social benefits, promising a bright future and improving the overall practicality of the device.

[0018] This invention uses a ceramic protective block to limit the auxiliary grooves on both sides of the ceramic tile strip during installation, and uses tile adhesive to fix the ceramic tile strip to the surface of the tread plaster layer. This design makes the installation of the ceramic tile strip more convenient and stable, and makes the installation process more convenient. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-4 This embodiment of an active stair tread corner protection device includes a concrete tread 1, a tread surface layer 2 fixedly connected to the upper end of the concrete tread 1, a protective block 3 further connected to the upper end of the concrete tread 1, a ceramic tile strip 4 provided at the upper end of the tread surface layer 2, auxiliary grooves 5 opened on both sides of the ceramic tile strip 4, a drainage groove 6 opened at the upper end of the ceramic tile strip 4, and a connecting groove 7 opened at the lower end of the ceramic tile strip 4. The reaction force at the end of the ceramic tile strip 4 is used, and the hard ceramic tile strip 4 resists and cancels the pressure force of daily pedestrian traffic on the tread, effectively preventing disturbance at the end of the stair tread and causing local chipping or breakage of corners.

[0028] The surface of the protective block 3 is engaged with the inner wall of the auxiliary groove 5, and the tread plaster layer 2 and the ceramic tile strip 4 are fixedly connected by tile adhesive.

[0029] The inner wall of the connecting groove 7 is in contact with the surface of the step surface layer 2.

[0030] The ceramic tile strip 4 is made of acid and alkali resistant material, which can effectively extend the service life of the ceramic tile strip 4, avoid damage or fading of the tile surface due to chemical corrosion, and improve the overall practicality of the device.

[0031] The surface of the step surface layer 2 is in contact with the side end of the protective block 3.

[0032] The drainage groove 6 is located at the upper end of the auxiliary groove 5.

[0033] The protective block 3 is located on both sides of the porcelain brick strip 4.

[0034] The implementation principle of the active stair tread corner protection device in this application embodiment is as follows: When installing the device, first place uniform-sized ceramic tile strips 4 in the work area, and inspect their appearance before construction to ensure that they are intact and free of damage or scratches. Then, lay out the upper end of the stair tread plaster layer 2. At the same time as laying out, apply tile adhesive evenly to the lower end of the ceramic tile strips 4, so that it is evenly distributed on the lower end of the ceramic tile strips 4 and the inner wall of the connecting groove 7. Then, align the auxiliary grooves 5 on both sides with the protective blocks 3 and attach them to the upper end of the stair tread plaster layer 2. After the attachment is completed, tap with a rubber mallet to ensure effective bonding between the tile adhesive and the ceramic tile strips 4 together with the stair tread plaster layer 2. After the construction of the continuous operation section is completed, water curing is carried out to ensure the bonding between the stair tread plaster layer 2 and the ceramic tile strips 4. The full reaction of the tile adhesive prevents cracks and voids, thus completing the installation of the protective device. The finished device features smooth lines and is economical and practical. In particular, the interplay between the ceramic tile strips 4 at the front of the concrete tread 1 and the tread plaster layer 2 creates a high-quality feel, resulting in a seamless, structurally sound tiling effect. This device offers significant economic and social benefits. The hard ceramic tiles 4 resist and offset the pressure exerted by daily foot traffic on the treads, effectively preventing disturbance at the ends of the stair treads and avoiding chipped edges. Furthermore, this device is not only economical and easy to install, but the tread plaster layer 2, with the ceramic tile strips 4 as its carrier, adds value to the overall tiling process, resulting in excellent economic and social benefits. Its application prospects are promising and it is worthy of promotion.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
