摘要： PROBLEM TO BE SOLVED: To prevent the generation of coating defects that are caused when a powder floating around a powder nozzle adheres to the nozzle, or the like, to become a molten drop at the time of the application of powder coating to the inner surface of a pipe. SOLUTION: A powder coating apparatus is formed into an integrated triple structure by a sheath pipe 3 covering a part of the rear portion of a powder nozzle 1 or the whole of a lance 2, and an annular space formed by the inner peripheral surface 31 of the sheath pipe 3 and the outer peripheral surface of an outer pipe 22 of the lance 2 is set to a reflux circuit 23 communicating with a suction device 4 generating air streams in the direction reverse to the feed direction of powder paint P. Adhering paint or floating powder paint ready to adhere is always removed by air streams in the direction always sucking air around the powder nozzle. If a structure making the axial line C1 of the lance 2 eccentric downwardly with respect to the axial line Cs of the sheath pipe 3 is set, the excessive flow of air under the powder nozzle is suppressed even in a suction state not only to minimize the influence on a coating pattern but also to obtain balance enhancing the removal effect on adhering paint.

摘要： PROBLEM TO BE SOLVED: To obtain the seal coat material capable of being coated on a cement- hardened substrate such as the mortar lining of a cast steel pipe to prevent the elusion of an alkaline substance, etc. SOLUTION: This penetrable waterproof composition comprises (A) a vinylic polymer containing 2-20wt.% of an acid monomer and (B) the mixture of an epoxy group-containing organoalkoxysilane and an organoalkoxysilane in a (A)/(B) ratio of 0.1-10. The organo alkoxysilane in the composition penetrates into a substrate to reinforce the substrate and form a water-repelling layer, and the vinylic polymer forms a resin layer for protecting the water-repelling layer. Since the acid groups especially react with the epoxy groups to improve the adhesive strength between both the layers, higher water resistance than those by conventional techniques is formed, and the function is maintained over a long period to solve problems.

摘要： PROBLEM TO BE SOLVED: To provide a pile joint structure and a connection member capable of transmitting rotational torque generated while driving a pile simply and securely and ensuring satisfactory rigidity of a connection part of piles.
SOLUTION: This pile joint structure is constituted by forming a receiving part 2 having a circular cross section in the direction of shaft axis on an inside diameter face on a tip side of a socket of the lower pile 1a and forming a female type transmission part 3 having a hexagonal cross section in the direction of shaft axis continuously with the receiving part 2 in the direction of shaft axis on an inside diameter face on an innermost side of the socket. On the other hand, a male type transmission part 5 being engaged with the female type transmission part 3 and having a hexagonal cross section in the direction of shaft axis is formed at a tip of an insertion port of the upper pile 1b, and an insertion part 6 being engaged with the receiving part 2 and being circular in the direction of shaft axis is formed continuously with the male type transmission part 5 in the direction of shaft axis on an outside diameter face on a root side of the insertion port. When the insertion port of the upper pile 1b is inserted into the socket of the lower pile 1a, both of the transmission parts 3, 5 are mutually engaged to transmit rotational torque simply and securely. Since both of the receiving part 2 and the insertion part 6 have circular cross sections, this structure can prevent the occurrence of deflection without depending on the direction of bending moment.
