摘要： PROBLEM TO BE SOLVED: To inexpensively facilitate working by being composed of a nut body and a plate body, and making the plate body an area enough to cover the opening of the sleeve part a screw mortar joint. SOLUTION: A screw node reinforcing bar fixing jig comprises a nut body 2 having a screw hole cutting a spiral recess groove 3 screwed with the screw hole 4 and a disk-like plate body 5 having an area covering a sleeve opening part. In addition, a strip-like notch part leading to the insertion hole of a center part is formed from one part of the peripheral edge of the plate body 5. The jig is screwed with the nut body 2 to be loosely fixed on an upper screw node reinforcing bar, thereafter, the nut body 2 is rotated to be moved downward, the plate body 5 is attached on the opening of a sleeve part by pressure, and the upper screw node reinforcing bar and a joint are fixed. Thereby fixing of a reinforcing bar cage and vertical adjustment are easily enabled at an inexpensive cost, and further a nut part rotation distance can be shortened.

摘要： PROBLEM TO BE SOLVED: To prevent rust before a steel material is embedded in a concrete or to prevent corrosion after the material is embedded, and to improve affinity with a concrete by depositing a water-soluble satd. carboxylic acid metal salt on the surface of a steel material. SOLUTION: As for the water-soluble satd. carboxylic acid metal salt to be deposited on the surface of a steel material, metal salts of naphthenic acid is preferably used from the viewpoint of availability. The metals to form salts are preferably alkali metals, especially Li, K and Na considering the solubility with water. These alkali metals have high ionization tendency so that they are instantly dissolved in water drops or a water film depositing on the surface of a steel material and shows a corrosion preventing effect. These metals belong strong bases and have about 10 to 13 pH as metal salts, and are preferable from the viewpoint of affinity with a concrete. The deposition amt. of the satd. carboxylic acid metal salts is preferably >=1×10 g/m calculated as the amt. of metals.
