Description of the invention (1) Scope of the invention The present invention relates to a cathodic protection method using a sacrificial anode for reinforcing steel bars in reinforced concrete, especially an electrical connector for connecting the sacrificial anode to a reinforced steel bar to be protected against money, and the installation of the anode. Methods. BACKGROUND OF THE INVENTION • The sacrificial anode method is an existing technology. To be effective, the sacrificial anode is made of metal, which has a higher negative electrode potential than the steel bar to be protected, so that it is corroded before the steel bar. The sacrificial anode method is described in European Patent No. 0 ^ and U.S. Patent No. 5292411. Problems solved by the invention In order to achieve the purpose of anti-corrosion of steel bars, the sacrificial anode must be electrically connected to the steel bars to be protected. For the purpose of _ a μ for the purpose of b, 'the existing metal conductor, such as a wire', was used on reinforced steel bars = small holes and self-tapping screws were inserted into the reinforced steel bars. Another method 疋 Use a clip to fix the wire on the steel bar to be protected from the last name. The problem with the age method is that drilling and picking are right, and lost children are always at risk of being removed.

The equivalent of sodium hydroxide is 2% = :: The amount of lithium hydroxide is greater than 2%, or the equivalent of 4% of sodium hydroxide is chlorinated. It is a better test, because the ions in the concrete can be avoided. The test lithotripsy (or test aggregate) reacts, but test mixtures such as a mixture of lithium hydroxide and sodium hydroxide can also be used. Anodes, porous materials such as slurries, and their casting can also be as described in European Patent No. 0707667.

The preferred anode is Zinc, under this condition, the pH value of the electrolyte is at least 14. When the anode is other metals such as aluminum, the pH value can be lower, such as at least 13. 3 or 13. 5. The pH value can be measured by the concentration of hydroxide ions It is determined by using the following equation: State = 14 + 10 g⑼ (according to Sorensen's) The present invention is suitable for the construction of new reinforced concrete structures in which the anode is connected to the reinforced steel concrete with a connector, and a type such as cement Porous material with a high Qiu value is cast around the anode. The invention is also applicable to the corrosion protection of existing concrete structures, where a hole can be drilled in the concrete, and then (i) the anode is inserted into the hole, (ii) Connect the connector to reinforced steel bars and (iii) cast a high pH material around the anode.

The description of invention (6) is to make it easier to use tools generally used to seal potato paper bags. -A suitable device is an impeachable ratchet twist articulation jig, such as a smoke binding tool, which can be constructed from the Direct Wire Ties coffee cup. With this tool, a steel wire arm reinforced with reinforced steel (not shown) is wound around the reinforced concrete. The part is hinged at-up. This has the effect of tightly binding the steel wire to the reinforced steel bar. In the first picture, a piece of reciprocating cylindrical block 20 with a diameter of about 40 mm and a thickness of about 7 mm has been cast around the twisted hinge steel wire. In the figure, the middle part of the cylindrical block 20 is omitted to show the steel. Line, the top and bottom edges of the cylindrical block 2 () have been chamfered to avoid cracking. The manufacturing sound of the assembly shown in the second picture is that the steel wires are twisted together at the middle position of their lengths, and the twisted hinges are placed in a ceramic mold, and then the molten zinc is washed into the mold and cured. After that, the finished product is taken out of the mold, and # 部 2, 4, 8, 10 extend on both sides of the anode, so that the anode can be connected with more than one reinforcing steel bar when necessary. In the second figure, a mud block 24 is cast around the phrase shown in the second figure to produce a thickness of 10 mm over the entire periphery of zinc. The assembly shown in the third figure is to place zinc in the middle of the mold by placing the assembly shown in the second figure in a plastic mold that has been vacuum-formed in advance. A high pH cement slurry containing a porous material having a pH value greater than 14 is produced by mixing water of a Portland cement powder (the addition of a bell hydroxide so that the cement powder contains 2% by weight of lithium hydroxide). , And poured it into a mold, the cement slurry was cured after 4 hours, and then removed from the mold to produce a finished product as shown in the third figure. ---------- # 蟪 (Please read the notes on the back before filling this page) Order! ------ # >#.
