[0002] In modern construction, the main reinforcement bars in the post-cast strip of the ground beam need to extend into the concrete layer. After the superstructure is completed, construction workers pour concrete into the work pit. However, the construction period for the superstructure is relatively long. During this period, the main reinforcement bars are exposed to the air for extended periods, making them prone to rusting. Therefore, there is a technical problem regarding the rusting of the main reinforcement bars in the post-cast strip of the ground beam during the construction period.

[0003] Therefore, it is necessary to provide a rust-proof structure for the post-cast reinforcement of the ground beam to solve the above-mentioned technical problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

[0024] In the diagram, units with similar structures are represented by the same labels.

[0025] Please refer to Figure 1 , Figure 2 and Figure 3 This utility model provides a rust-proof structure 10 for the reinforcing bars of a post-cast strip in a ground beam. A cushion layer 12 is provided above the original soil layer 11, and the rust-proof structure 10 for the reinforcing bars of the post-cast strip in the ground beam is located above the cushion layer 12. The rust-proof structure 10 includes two concrete layers 13, multiple main reinforcing bars 15, and a zinc metal structure 18. The two concrete layers 13 are horizontally spaced apart, with a working pit 14 between them. The multiple main reinforcing bars 15 extend horizontally and are located within the working pit 14. Both ends of the main reinforcing bars 15 extend into the two concrete layers 13. The zinc metal structure 18 is disposed on the outer surface of each main reinforcing bar 15 and is electrically connected to the main reinforcing bars 15. Furthermore, the main reinforcing bars 15 are made of iron. When zinc and iron are exposed to air together, zinc, due to its higher metallic activity, will preferentially oxidize as the anode (Zn→Zn). 2+ +2e-), while iron is protected as the cathode. The specific chemical reaction formula between zinc and oxygen is as follows: Anode: Zn=Zn 2+ +2e - Cathode: O2 / 2 + H2O + 2e - =2OH - CO2 + 2OH - =CO3 2- +H2O Overall reaction: Zn + O2 / 2 + CO2 + H2O = ZnCO3 + H2O Therefore, through the chemical reaction between zinc and oxygen, the zinc metal structure 18 effectively protects the main reinforcement 15. Consequently, even if the main reinforcement 15 is exposed to air for extended periods during the construction period, it will not rust. This effectively solves the technical problem of the main reinforcement 15 in the post-cast strip of the ground beam easily rusting during the construction period. Furthermore, during construction, the zinc metal structure 18 is removed before pouring the concrete 19; the zinc metal structure 18 can then be used to prevent the main reinforcement 15 from easily rusting during the construction period.

[0026] Please refer to Figure 1 and Figure 2 The zinc metal structure 18 is a mesh structure that wraps around the outside of the main reinforcing bar 15. The zinc metal structure 18 is a galvanized welded wire mesh with multiple diamond-shaped holes, preferably with a hole diameter of 10-20 mm. The zinc layer adhesion is greater than or equal to 60 g / m². Because the hole diameter is 10-20 mm, a large number of diamond-shaped holes can be provided on the galvanized welded wire mesh. Furthermore, the diamond-shaped holes can be evenly distributed on the galvanized welded wire mesh. Thus, the reinforcing bar can be evenly and fully exposed to the air. Zinc and iron can fully react chemically, thereby effectively improving the protective effect of the galvanized welded wire mesh on the main reinforcing bar 15.

[0027] In another embodiment, the zinc metal structure 18 is filamentous, and the filamentous zinc metal structure 18 is wound around the outside of the main rib 15. Preferably, in the filamentous zinc metal structure 18, the diameter of the mesh wire is greater than or equal to 0.7 mm. The zinc metal structure 18 includes forward-winding wires and reverse-winding wires. The forward-winding wires and reverse-winding wires are spirally wound around the outside of the main rib 15 and intersect to form a mesh structure. The spiral winding of the forward-winding wires and reverse-winding wires ensures that the formed zinc metal structure 18 is in close contact and electrically connected to the main rib, thereby improving rust prevention performance.

[0028] Please refer to Figure 1 and Figure 2The two ends of the zinc metal structure 18 abut against the concrete layer 13, or the distance between the two ends of the zinc metal structure 18 and the adjacent concrete layer 13 is less than 5 cm. Therefore, the area of ​​the zinc metal structure 18 covering the outer surface of the main reinforcement 15 is relatively large. Furthermore, the main reinforcement 15 can fully react chemically with the zinc metal structure 18, which is beneficial to improving the protective effect of the galvanized welded wire mesh on the main reinforcement 15. The anti-rust structure 10 for the post-cast strip reinforcement of the ground beam also includes multiple fixing zinc wires 17. The fixing zinc wires 17 are wrapped around the outside of the zinc metal structure 18, and the two ends of the fixing zinc wires 17 are intertwined, making the zinc metal structure 18 tightly attached to the main reinforcement 15. The fixing zinc wires 17 can be used to fix the zinc metal structure 18. Because the two ends of the fixing zinc wires 17 are intertwined, making the zinc metal structure 18 tightly attached to the main reinforcement 15, the connection between the zinc metal structure 18 and the main reinforcement 15 is relatively stable. Therefore, the fixing zinc wires 17 can fix the zinc metal structure 18 to the main reinforcement 15 for a long time. The fixing zinc wire 17 is tightened in a figure-eight knot, and each fixing zinc wire 17 must penetrate the zinc metal structure 18 and be wrapped around the reinforcing bar. This ensures that the mesh is tightly attached to the surface of the reinforcing bar, avoiding gaps between the zinc metal structure 18 and the main reinforcing bar 15 that would reduce the rust prevention effect.

[0029] Please refer to Figure 3 The reinforced concrete support structure also includes multiple stirrups 16, which can be installed after the zinc metal structure 15 is removed by construction workers. The stirrups 16 are located inside the working pit 14, are vertically aligned, and connect to the main reinforcement 15. The stirrups 16 are arranged along the length of the main reinforcement 15, which increases the connection strength between the main reinforcement 15 and the concrete layer 13, thus improving the stability of the connection between them.

[0030] Please refer to Figure 1 and Figure 2 Both ends of the zinc metal structure 18 are provided with end extension structures, the length of which is greater than or equal to 50 mm. The end extension structures are bent away from the adjacent concrete layer 13 and are pressed against the outside of the zinc metal structure 18. Therefore, the zinc metal structure 18 can be firmly fixed to the outside of the main reinforcement 15, allowing for a tight electrical connection between the zinc metal structure 18 and the main reinforcement 15. This, in turn, improves the chemical reaction effect between the zinc metal structure 18 and the main reinforcement 15.

[0031] Please refer to Figure 3The working pit 14 includes an interconnected rectangular pit 142 and a trapezoidal pit 141. The longitudinal section of the rectangular pit 142 is rectangular, and the longitudinal section of the trapezoidal pit 141 is trapezoidal. The trapezoidal pit 141 is recessed into the foundation layer 12 and the original soil layer 11, and the rectangular pit 142 is located at the upper end of the trapezoidal pit. The main reinforcement 15 and stirrups 16 are located inside the rectangular pit, and concrete 19 can be poured into the interior of both the rectangular and trapezoidal pits. The structure of this working pit 14 allows for the pouring of more concrete 19, thereby making the rust-proof structure of the ground beam reinforcement more stable.

[0032] The installation process of this utility model is as follows: First, the construction workers excavate the original soil layer 11 and pour a foundation layer 12 on top of the original soil layer 11. Then, a working pit 14 is formed above the foundation layer 12, and the construction workers install the main reinforcement bars 15 in the working pit 14 according to the construction drawings. The main reinforcement bars 15 extend horizontally. Next, the construction workers pour a concrete layer 13, which is placed on both sides of the anti-rust structure 10 of the reinforcing steel strip in the ground beam. The two ends of the concrete layer 13 extend into the two concrete layers 13 respectively, thus fixing the main reinforcement bars 15. The construction workers wrap a zinc metal structure 18 around the outside of the main reinforcement bars 15, and the zinc metal structure 18 is tied to the outer surface of the main reinforcement bars 15 using fixing zinc wire 17. After the construction of the superstructure is completed, the construction workers remove the zinc metal structure 18 and clean the working pit 14. Construction workers install stirrups 16 in the work pit 14 according to the construction drawings. The stirrups 16 are set vertically and arranged along the length of the main reinforcement 15. Then, the construction workers tie the stirrups 16 and the main reinforcement 15 together with wire. The construction workers can then pour concrete 19 in the work pit 14 to complete the construction.

[0033] This utility model provides a rust-proof structure for the reinforcing bars in the post-cast strip of a ground beam. This structure includes two concrete layers, multiple main reinforcing bars, and a zinc metal structure. A working pit is provided between the two concrete layers, and the main reinforcing bars are located within the working pit. A zinc metal structure is provided on the outer surface of each main reinforcing bar, and the zinc metal structure is electrically connected to the main reinforcing bar. Furthermore, the main reinforcing bar is made of iron. When zinc and iron are exposed to air together, zinc, due to its higher metallic activity, will preferentially oxidize as the anode, while iron will be protected as the cathode. Therefore, through the chemical reaction between zinc and oxygen, the zinc metal structure effectively protects the main reinforcing bars. Consequently, even if the main reinforcing bars are exposed to air for extended periods during the construction period, they will not rust. This effectively solves the technical problem of easy rusting of the main reinforcing bars in the post-cast strip of the ground beam during the construction period, and the zinc metal structure effectively protects the main reinforcing bars of the post-cast strip from corrosion.

Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
