One end of the main tread plate in each tread is spliced ​​to one end of the side tread plate, and the other end of the side tread plate is spliced ​​to the main tread plate of the adjacent tread plate. The upper and lower water-retaining plates are located on both sides of the multiple treads, and the upper edge of the upper water-retaining plate extends outwards to form multiple treads. The end of the main tread plate that is fixedly connected to the side tread plate extends out of the side tread plate, and its extended portion is provided with a drip line. The side wall of the main tread plate connected to the lower water-retaining plate also extends out of the side tread plate, and its extended portion is also provided with a drip line. It not only has good waterproof function, but also has a simple and sturdy structure, requires no processing or adhesives, does not damage the original texture and gloss of the product during installation, saves energy, and also has anti-slip function.

[0003] The aforementioned and existing technologies for reinforcing stair treads typically involve evenly distributing steel bars of a certain specification and quantity inside the tread, or pouring concrete of a specific thickness. This fixed-strength design, once determined, cannot be adjusted according to changes in actual usage scenarios. Whether facing public buildings with high foot traffic, industrial buildings with special load requirements, or residential floors with varying usage frequencies, it can only address the issue with the same strength standard, failing to achieve precise adaptation to different scenarios. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology that cannot adjust the strength of the reinforcement structure of the stair tread according to different application scenarios, and to propose a building stair tread anti-slip safety reinforcement structure.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a building stair tread anti-slip safety reinforcement structure, including stair joists, two stair joists with treads arranged in an oblique array between them, two stair joists with oblique array limiting grooves on their surfaces, three mounting grooves evenly spaced on the bottom surface of the limiting grooves on the surfaces of the two stair joists, three slots on the top surface of each tread, three anti-slip strips on the top of each tread, a slot on the bottom surface of each tread, a steel frame at the bottom of each tread, three reinforcing ribs at the bottom of each steel frame, a fixing bracket at each corner of each tread, and fixing bolts on one side of each of the four fixing brackets.

[0006] Preferably, the two stair joists are mirror images of each other with the tread as the center, and the limiting grooves on the surface of the stair joists are all located on the side close to the tread, and the positions of the limiting grooves correspond one-to-one with the positions of the treads.

[0007] Preferably, the fixing brackets at each corner of the step plate are integrally formed with the step plate, and both ends of the step plate are installed in the limiting grooves on the surface of the stair joists at both ends of the step plate. The fixing brackets at each corner of the step plate are fixed in the limiting grooves by fixing bolts.

[0008] Preferably, the three slots on the top surface of the step plate are all located at one end of the step plate, and the three anti-slip strips on the top of the step plate are all installed in the slots, and the anti-slip strips are all inserted into the slots.

[0009] Preferably, the three mounting grooves on the bottom surface of the limiting groove are all set on the surface of the stair joist, and the limiting grooves are all connected to the mounting grooves.

[0010] Preferably, the positions of the three reinforcing ribs at the bottom of the step plate correspond one-to-one with the positions of the mounting grooves, and both ends of the reinforcing ribs are installed in the mounting grooves on the surface of the stair joists on both sides of the step plate, and the three reinforcing ribs are all in contact with the step plate.

[0011] Preferably, the steel frames at the bottom of the step plate are all installed in the slots on the bottom surface of the step plate, and the steel frames are all bonded to the step plate.

[0012] Beneficial effects

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0023] Reference Figure 1-4A structural anti-slip and safety reinforcement structure for building stair treads includes stair joists 1, two stair joists 1 with treads 2 arranged diagonally between them, two stair joists 1 with diagonally arranged limiting grooves 5 on their surfaces, three equally spaced mounting grooves 6 on the bottom surface of the limiting grooves 5 on the surfaces of the two stair joists 1, three slots 3 on the top surface of each tread 2, three anti-slip strips 4 on the top of each tread 2, slots 8 on the bottom surface of each tread 2, a steel frame 9 at the bottom of each tread 2, three reinforcing ribs 7 at the bottom of each steel frame 9, and fixing brackets 10 at each corner of each tread 2. Each of the four fixing brackets 10 has a fixing bolt 11 on one side. The two stair joists 1 are mirror images of each other with respect to the tread 2. The limiting grooves 5 on the surface of the stair joists 1 are all located on the side closest to the tread 2, and the positions of the limiting grooves 5 correspond one-to-one with the positions of the tread 2. The fixing brackets 10 at each corner of the tread 2... All are integrally formed with the tread plate 2, and both ends of the tread plate 2 are installed in the limiting grooves 5 on the surface of the stair joists 1 at both ends of the tread plate 2. The fixing brackets 10 at each corner of the tread plate 2 are fixed in the limiting grooves 5 by fixing bolts 11. The three slots 3 on the top surface of the tread plate 2 are all set at one end of the tread plate 2. The three anti-slip strips 4 on the top of the tread plate 2 are all installed in the slots 3 and are inserted into the slots 3. The three mounting grooves 6 on the bottom surface of the limiting grooves 5 are all set on the surface of the stair joists 1 and are connected to the mounting grooves 6. The positions of the three reinforcing ribs 7 at the bottom of the tread plate 2 correspond one-to-one with the positions of the mounting grooves 6. Both ends of the reinforcing ribs 7 are installed in the mounting grooves 6 on the surface of the stair joists 1 on both sides of the tread plate 2. The three reinforcing ribs 7 are all attached to the tread plate 2. The steel frame 9 at the bottom of the tread plate 2 is installed in the slots 8 on the bottom surface of the tread plate 2 and is bonded to the tread plate 2.

[0024] The stair joists 1 are the basic supporting components of the staircase, bearing the entire staircase structure and pedestrian loads. The limiting grooves 5 on their surface provide positioning and installation space for the treads 2, ensuring accurate placement. The mounting grooves 6 are used in conjunction with reinforcing ribs 7 to adjust the reinforcement strength of the treads 2. The treads 2 serve as the working surface for pedestrians, and are installed by embedding them into the limiting grooves 5 of the stair joists 1 at both ends. The slots 3 on the top surface are used to install anti-slip strips 4, improving anti-slip performance; the slots 8 on the bottom surface are used to fix the steel frame 9, enhancing its structural strength; the fixing brackets 10 at the corners cooperate with fixing bolts 11 to securely connect the treads 2 to the stair joists 1. The slots 3 provide installation interfaces for the anti-slip strips 4, allowing them to be fixed to the top surface of the treads 2 via a plug-in method to perform their anti-slip function. The anti-slip strips 4 are typically made of materials with a high coefficient of friction, such as rubber, and are installed in the slots 3 to increase the friction between the pedestrian's shoe sole and the treads 2, preventing slips. The limiting groove 5 is formed on the surface of the stair joist 1, matching the shape of both ends of the tread 2, restricting the horizontal movement of the tread 2, ensuring installation accuracy, and facilitating the connection and fixation of the fixing bracket 10 and fixing bolts 11. The mounting groove 6 is located on the bottom surface of the limiting groove 5 and is adapted to the reinforcing rib 7. When it is necessary to increase the strength of the tread 2, the reinforcing rib 7 can be inserted into it; if it is necessary to reduce the strength or make adjustments, the reinforcing rib 7 can be removed. The reinforcing rib 7 is generally made of high-strength material. After being inserted into the mounting groove 6, it fits against the bottom surface of the tread 2, enhancing the load-bearing capacity and deformation resistance of the tread 2. The overall strength of the tread 2 can be adjusted by adding or removing it. The slot 8 is on the bottom surface of the tread 2 and is used to position and fix the steel frame 9, so that the steel frame 9 is tightly combined with the tread 2 to jointly bear the load. The steel frame 9 is installed in the slot 8 and bonded to the tread 2, further improving the structural strength of the tread 2 and effectively dispersing the stress generated by the load. The fixing bracket 10 is integrally formed with the step plate 2 and is located at the corner. It has mounting holes for the fixing bolts 11 to pass through, so as to firmly connect the step plate 2 to the limiting groove 5 of the stair joist 1 and prevent loosening and falling off. The fixing bolts 11 pass through the mounting holes of the fixing bracket 10 and screw into the stair joist 1 to fasten the fixing bracket 10 to the stair joist 1, so as to achieve reliable fixation of the step plate 2. Specific Implementation Example 2:

[0026] Reference Figure 1-4A structural reinforcement structure for anti-slip safety of building stair treads is further based on the basic structure in Specific Embodiment 1. Under normal use, the tread plate 2 is embedded at both ends into the limiting grooves 5 of the stair joists 1, and fixed by the fixing bracket 10 and fixing bolts 11. The steel frame 9, within the slot 8, works in conjunction with the tread plate 2 to bear the load, and the anti-slip strip 4 provides anti-slip protection within the slot 3. When the reinforcement strength of the tread plate 2 needs to be adjusted due to changes in the application scenario, first unscrew the fixing bolts 11, pull the tread plate 2 out of the limiting groove 5, then, as needed, insert or remove the reinforcing rib 7 into the installation slot 6, then re-embed the tread plate 2 into the limiting groove 5, and finally fix the fixing bracket 10 with the fixing bolts 11. By changing the installation of the reinforcing rib 7, the load-bearing and deformation resistance of the tread plate 2 can be adjusted to adapt to the strength requirements of different application scenarios.

[0027] In summary:

[0028] 1. When it is necessary to adjust the reinforcement strength of the stair tread 2, the fixing bolts 11 of the fixing brackets 10 on each corner of the stair tread 2 are removed, and the stair tread 2 is pulled out from the limiting groove 5 of the stair joist 1. After being pulled out, the reinforcing ribs 7 are either put into the installation groove 6 of the stair joist 1 or taken out of the installation groove 6, depending on the different application scenarios. After the reinforcing ribs 7 are taken out or put in, the two ends of the stair tread 2 are reinstalled in the limiting groove 5 of the stair joist 1, and the fixing brackets 10 at each corner of the stair tread 2 are fixed in the limiting groove 5 again by fixing bolts 11, thereby completing the fixed installation of the stair tread 2. By installing or removing the reinforcing ribs 7, the overall strength of the stair tread 2 can be changed, which solves the problem of not being able to adjust the reinforcement strength of the stair tread 2 according to different application scenarios.
