Description

Technical Field

[0001] This utility model belongs to the field of anti-slip construction technology for stairs, and in particular relates to a connection structure for anti-slip strips on cement stair treads. Background Technology

[0002] Cement staircases are a common choice for duplex or split-level residences due to their low cost and durability, especially suitable for those with limited budgets or those who prefer an industrial or minimalist style. The connection structure of anti-slip strips for cement staircase treads mainly uses diamond-coated anti-slip strips, which are fixed by embedding or pasting. They need to be tightly bonded to the cement base surface, taking into account both anti-slip performance and ease of construction.

[0003] The embedded installation of anti-slip strips on cement stair treads mostly relies on adhesive force for fixation. However, due to long-term pressure from footsteps, they may loosen and detach over time. Therefore, a connection structure for anti-slip strips on cement stair treads is needed. This structure can use a connecting frame to fix the anti-slip strips to the concrete foundation of the staircase, improving the stability of the anti-slip strip structure and extending its service life. Utility Model Content

[0004] The purpose of this utility model is to provide a connection structure for anti-slip strips on cement stair treads. By connecting the frame, the anti-slip strip is fixed to the concrete foundation of the staircase, thereby improving the stability of the anti-slip strip structure and extending its service life, thus solving the technical problems mentioned in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A connection structure for anti-slip strips on cement-surfaced stair treads includes anchoring holes and a cement mortar surface layer set on the concrete foundation surface of the staircase; a rebar is inserted into the inner cavity of the anchoring hole; a U-shaped rod is sleeved on the surface of the rebar; a nut block is threadedly connected to the surface of the rebar; an anchoring adhesive layer is filled between the inner wall of the anchoring hole and the rebar; a diamond anti-slip strip is cast and formed on the surface of the cement mortar surface layer; a crossbar is welded to the surface of the U-shaped rod; a connecting rod and a first-piece cover are provided on the surface of the U-shaped rod; a second-piece cover is provided on the surface of the first-piece cover; a bolt rod is installed through the first-piece cover and the second-piece cover; a nut block is threadedly connected to the surface of the bolt rod.

[0006] Preferably, the surface of the rebar rod is integrally formed with support strips.

[0007] Preferably, the inner wall of the nut block and the anchor rod are both filled with a structural adhesive layer.

[0008] Preferably, the end of the crossbar extends into the inner cavity of the diamond anti-slip strip, and a circular plate is integrally formed on the surface of the crossbar.

[0009] Preferably, a triangular block is welded together between the U-shaped rod and the crossbar.

[0010] The beneficial effects of this utility model are: 1. This utility model uses a rebar rod and a nut block to fix the U-shaped rod to the stair foundation surface, and then uses a crossbar to connect and fix the diamond sand anti-slip strip to the U-shaped rod, so that the diamond sand anti-slip strip can be connected and fixed to the stair foundation. This achieves the purpose of fixing the anti-slip strip to the concrete foundation of the stair through the connecting frame, improving the stability of the anti-slip strip structure, and thus extending the service life of the anti-slip strip. 2. By setting up support bars, this utility model increases the contact area between the rebar rod and the anchoring adhesive layer, thereby improving the stability of the connection between the rebar rod and the inner wall of the anchoring hole. 3. This utility model uses a structural adhesive layer to bond the threaded connection between the nut block and the rebar rod, preventing the nut block from loosening due to external vibration during the subsequent pouring of cement mortar surface layer, thereby improving the stability of the rebar rod in fixing the U-shaped rod. 4. By setting up a circular plate, this utility model increases the contact area between the crossbar and the diamond anti-slip strip, improves the stability of the connection between the two, and reduces the possibility of them becoming loose and detaching from each other. 5. By setting up triangular blocks, this utility model strengthens the welding of the U-shaped rod and the crossbar, reducing the possibility of breakage at the connection surface between the two, thereby improving the stability of the connection.

[0013] In the following description, embodiments of the anti-slip strip connection structure for cement stair treads according to the present invention will be described with reference to the accompanying drawings.

[0014] Example 1: Figure 1-4 This invention illustrates a connection structure for anti-slip strips on cement-surfaced stair treads, comprising anchoring holes 1 and a cement mortar surface layer 2 on the concrete foundation surface of the staircase. A rebar 3 is inserted into the inner cavity of the anchoring hole 1. A U-shaped rod 4 is fitted onto the surface of the rebar 3. A nut block 5 is threaded onto the surface of the rebar 3. An anchoring adhesive layer 6 is filled between the inner wall of the anchoring hole 1 and the rebar 3. A support strip 7 is integrally formed on the surface of the rebar 3. The support strip 7 increases the contact area between the rebar 3 and the anchoring adhesive layer 6, thereby improving the stability of the connection between the rebar 3 and the inner wall of the anchoring hole 1. The nut block 5 is threaded onto the inner wall of the rebar 3. The structural adhesive layer 8 is used to bond the threaded connection between the nut block 5 and the rebar rod 3, preventing the nut block 5 from loosening due to external vibration during the subsequent pouring of the cement mortar surface layer 2. This improves the stability of the rebar rod 3 in fixing the U-shaped rod 4. The surface of the cement mortar surface layer 2 is cast with a diamond anti-slip strip 9. The surface of the U-shaped rod 4 is welded with a crossbar 10. The surface of the U-shaped rod 4 is provided with a connecting rod 12 and a first-sized cover block 13. The surface of the first-sized cover block 13 is provided with a second-sized cover block 14. A bolt rod 15 is installed through the first-sized cover block 13 and the second-sized cover block 14. The surface of the bolt rod 15 is threadedly connected with a second-sized nut block 16.

[0015] Example 2: Figure 1-4This invention illustrates a connection structure for anti-slip strips on cement-surfaced stair treads, comprising anchoring holes 1 and a cement mortar surface layer 2 on the concrete foundation surface of the staircase. A reinforcing bar 3 is inserted into the inner cavity of the anchoring hole 1. A U-shaped bar 4 is fitted onto the surface of the reinforcing bar 3. A nut block 5 is threaded onto the surface of the reinforcing bar 3. An anchoring adhesive layer 6 is filled between the inner wall of the anchoring hole 1 and the reinforcing bar 3. A diamond-coated anti-slip strip 9 is cast and formed on the surface of the cement mortar surface layer 2. A crossbar 10 is welded to the surface of the U-shaped bar 4. The end of the crossbar 10 extends into the inner cavity of the diamond-coated anti-slip strip 9. A circular plate 11 is integrally formed on the surface of the crossbar 10. The circular plate 11... The increased contact area between the crossbar 10 and the diamond anti-slip strip 9 improves the stability of their connection and reduces the possibility of them loosening and coming off. The surface of the U-shaped bar 4 is provided with a connecting rod 12 and a first-sized block 13. The surface of the first-sized block 13 is provided with a second-sized block 14. A bolt rod 15 is installed through the first-sized block 13 and the second-sized block 14. A second-sized nut block 16 is threaded onto the surface of the bolt rod 15. A triangular block 17 is welded between the U-shaped bar 4 and the crossbar 10. The triangular block 17 strengthens the weld between the U-shaped bar 4 and the crossbar 10, reduces the possibility of breakage at the connection surface, and thus improves the stability of the connection.

[0016] Working Principle: In use, the user opens anchoring holes 1 on the surface of the stair foundation, cleans the anchoring holes 1, and then injects anchoring adhesive layer 6. Next, the U-shaped rod 4 is fixed to the stair foundation surface by using the anchor rod 3 and nut block 1 5. Then, a crossbar 10 is welded to the surface of the U-shaped rod 4. Then, the bolt rod 15 and nut block 2 16 are used together to connect and reinforce the connecting rod 12 and the U-shaped rod 4 by using the first and second wrapping blocks 13 and 14, which improves the strength of the U-shaped rod 4 structure. Then, a cement mortar surface layer 2 and a diamond anti-slip strip 9 are poured on the surface of the stair foundation. The diamond anti-slip strip 9 is connected and fixed to the U-shaped rod 4 by the crossbar 10, so that the diamond anti-slip strip 9 is connected and fixed to the stair foundation. This realizes the fixation of the anti-slip strip to the concrete foundation of the stair through the connecting frame, improves the stability of the anti-slip strip structure, and thus extends the service life of the anti-slip strip.

[0017] In summary, the connection structure of this cement-surface stair tread anti-slip strip uses reinforcing bars 3 and nut blocks 5 to fix the U-shaped bar 4 to the stair base surface. Then, the crossbar 10 connects and fixes the diamond-coated anti-slip strip 9 to the U-shaped bar 4, thus connecting and fixing the diamond-coated anti-slip strip 9 to the stair base. This achieves the purpose of fixing the anti-slip strip to the concrete foundation of the stair through the connecting frame, improving the stability of the anti-slip strip structure, and extending the service life of the anti-slip strip.
