[0067] The working principle of this utility model:

[0068] 1. Install the marking device 9 on one side of the top of the second stirrup 5.

[0069] 2. Install the second stirrup 5 equipped with the marking device 9 and the several first stirrups 1 distributed in a linear array on the outside of the first steel bar 2 and the second steel bar 3, and tie them together with wire to form a basement floor beam support skeleton. At this time, the second stirrup 5 is located in the middle position of the several first stirrups 1 distributed in a linear array.

[0070] 3. When performing anti-corrosion on the first stirrup 1, the second stirrup 5, the first steel bar 2 and the second steel bar 3 exposed outside.

[0071] (1) The staff first cleans the steel bars to prevent previous dirt from adhering to the steel bars.

[0072] (2) The positive pole of the external power source is connected through the marking device 9 and the power connection device 10. The second stirrup 5 after being powered on serves as an anode, and the first stirrup 1, the first steel bar 2 and the second steel bar 3 are combined as a cathode, and a negative pole of the external power source is selected. Since the potential of the second stirrup 5 is lower than that of the first stirrup 1, the first steel bar 2 and the second steel bar 3, the metal of the conductive device 4 with a low potential will release electrons and undergo an oxidation reaction, thereby protecting the first stirrup 1, the first steel bar 2 and the second steel bar 3 with a high potential from corrosion.

[0073] The specific reaction formula is as follows:

[0074] Anode: M-ne - =M n+

[0075] Cathode: nO2 / 4+ne - +nH2O / 2=nOH -

[0076] Overall reaction formula: M+nO2 / 4+nH2O / 2=M n+ +nOH -

[0077] Among them, M represents low-potential metal (selected by design), n represents quantity, and e- represents electrons.

[0078] 4. Pour concrete on both sides of the middle of the support frame, so that the concrete can cover the first stirrup 1, the first steel bar 2 and the second steel bar 3 together, and then reserve the middle position of the basement floor beam for easy connection with other column steel bars.

[0079] The anti-corrosion structure provided in this embodiment improves the corrosion resistance of the first stirrup 1, the first steel bar 2 and the second steel bar 3, and the first stirrup 1, the second stirrup 5, the first steel bar 2 and the second steel bar 3 connected by wire binding can ensure good electrical connectivity. After the steel bars are energized for a period of time and the oxidation reaction of the steel bars is completed, the power supply can be removed without continuously energizing the steel bars.

[0080] When it is necessary to install the marking device 9 on the second stirrup 5:

[0081] First, the staff can install the second stirrup 5 in the receiving groove 92 of the clamping block 91 through the notch 93 on the clamping block 91 .

[0082] Secondly, by rotating the locking button 95 in the first screw hole 94 , the end of the first screw hole 94 can be slowly lowered and then engaged in the limiting groove 96 .

[0083] Then, since a through hole 982 for inserting the locking button 95 is provided on one side of the top surface of the connecting plate 981, when the locking button 95 rotates and moves downward, it will synchronously drive the connecting plate 981 to move downward, and then the connecting plate 981 can drive the pressure plate 984 to move downward together with the square rod 983, so that the pressure plate 984 clamps and limits a part of the second stirrup 5 installed in the accommodating groove 92.

[0084] This structure improves the installation stability of the clamping block 91 and the second stirrup 5. The fixing screw 911 can be rotatably installed in the inner cavity of the internal thread groove 910 and can also penetrate the bottom of a side wall of the power connection device 10, thereby being able to install and fix the power connection device 10.

[0085] When it is necessary to disassemble and separate the clamping block 91 and the second stirrup 5:

[0086] First, rotate the locking button 95 in the opposite direction, and the locking button 95 will slowly move upward; then, the sleeve 985 will be lifted up synchronously under the elastic force of the elastic member 986, and then the pressure plate 984 will be driven to move upward through the connecting plate 981 and the square rod 983, so that the staff can disassemble and separate the block 91 from the second stirrup 5, which is convenient for the later reuse of the marking device 9.

[0087] The metal plate 101 in the power connection device 10 can be installed on the fixing screw 911 through the axial hole 102, and a space can be provided for the wiring hole 103, so that the wiring hole 103 can be conveniently connected to the positive cable of the external power source, and then the metal plate 101 can transmit the electric energy to the block 91, so as to finally transmit it to the second stirrup 5.

[0088] The two water-stop steel plates 6 can effectively prevent moisture from penetrating from the joints of the post-cast strips, thereby limiting the flow of moisture inside the building or project and maintaining the stability and safety of the structure. The two anti-ridges 7 can lift the wooden formwork 8 so that the wooden formwork 8 can protect the first stirrup 1, the first steel bar 2, the second steel bar 3 and the second stirrup 5 exposed to the outside.

[0089] The elastic member in this embodiment is preferably a spring structure, and other structures in the concrete pouring operation of the basement floor beam post-cast steel anti-corrosion structure, such as the concrete pouring structure, are the main invention points of the prior art and this application, and will not be elaborated here.

[0090] The above are only preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
