摘要： PURPOSE:To perform joining between a column and a beam easily and firmly without installing any reinforcing member. CONSTITUTION:A wall thickness part 11a by means of induction heating and compression is installed in a part in the longitudinal direction of a steel pipe column 11, and an end part of a rolled steel beam 12 is bolted to this wall thickness part 11a of the column 11. This joining between the end part of the beam 12 and the wall thickness part 11a of the column 11 is carried out via a pair of split tees 13 bolted each to the wall thickness part 11a and vertical flanges 12a of the beam 12, but it may be done via an end plate of the beam. In addition, a one-side bolt may be used to a bolt 15 being inserted through the steel pipe column 11. In this connection, the joining of the end aprt of the beam 12 to the wall thickness part 11a of the column 11 may be done by means of welding as well.

摘要： PURPOSE:To prevent corrosion of a metal tube by producing a proper compressive surface pressure at a joint to seal internal fluid completely and prevent fluid from entering the joint, and also adding a metal with sacrificed positive pole action to the joint. CONSTITUTION:When a metal tube is lined with an elastic body such as rubber, polyurethane, etc., the thickness of the lining coating 4 at the joint end of the tube to be joined is adjusted according to the compressive stress-strain characteristic of the lining coating to produce a compressive stress with which any permanent strain is not produced in the lining coating by the amount of retraction in longitudinal direction produced by the welding of a sleeve 5. Thus the lining coatings are jointed to each other to prevent fluid from entering the clearance in the closely mounted part of the sleeve. Also a metal 6 with sacrificed positive pole action is added to the joint to prevent corrosion of the metal tube.

CONSTITUTION:After the outer surface of a base material 1 is degreased by trichloroethylene, grid blasting is applied to said base material and an adhesive polyethylene resin powder is applied thereto by a powder painting method to provide an adhesive layer 2. Next, a cylindrical body 3 composed of an ultrahigh MW polyethylene pipe is externally fitted to the outside of the base material under pressure to obtain a fitted cylindrical body. Subsequently, a high frequency heating coil 4 is arranged to the outside of the cylindrical body and the surface layer of the base material 1 is successively subjected to induction heating while said coil 4 is moved and the adhesive is melted to weld the base material 1 and the cylindrical body 3. Thereafter, the surface and end part of the cylindrical body are subjected to cutting processing.

摘要： PURPOSE:To weld covering material to the outer surface of pipe by a method wherein induction heating coil is provided so as to surround pipe, on which heat-shrinkable covering material is mounted, in order to uniformly heat the pipe. CONSTITUTION:Induction heating coil is so designed that furnace temperature is the highest at the middle in axial direction and becomes gradually lower toward both ends. Firstly, heat-shrinkable covering material 13, onto the inner surface of which bonding layer made of hot-meltable resin, is mounted onto the outer surface of pipe 2. Next, when a hot welding device 1, which is mounted around the pipe 2 so as to bring the axial center of the induction heating coil 7 in line with the center of the covering material 13, is energized. the temperature of the induction heating coil 7 rises, resulting in heating the covering material 13 and, at the same time, furnace space by radiant heat. Further, simultaneously, the temperature of the pipe 2 is also raised by induction heating and the temperatures at the middle of the furnace and of the covering material 13 become high. As the covering material 13 starts to shrink at its middle so as to be brought into close contact with the outer surface of the pipe and the contact between the outer surface of the pipe and the covering material proceeds to both ends of the pipe, no bubble is left between the outer surface of the pipe and the covering material 13. The contacting part of the covering material 13 and film 12 is heated from outside and from the pipe 2 so as to be melted. By deenergizing, the covering material 13 is satisfactorily welded to the outer surface of the pipe 2 and of the film 12 lying beneath the covering material.

摘要： PURPOSE:To make possible the prevention of deterioration of working environments, improvement of material yield and application of a uniformly thick coat by ejecting resin powder in a spraying box, and applying/melting the resin powder on the surface of a metal to be heated, while aspirating and recovering a floating resin powder which does not stick and melt. CONSTITUTION:An exposed metal section 12 is heated from an opposite side to a spraying box 42 by a burner 21 of a heating device 2 at more than a melting-point temperature of resin powder 63. Consequently, the resin powder 63 ejected from a spray nozzle 45 in the spraying box 42 melts, and sticks and melts with the existing lining coat into a mixed film. The portion which does not stick and melt of the resin powder 63 ejected from the spray nozzle 45 floats in the spraying box and then is sucked into a powder recovery device 6. Thus the density of powder can be controlled. Therefore, the coat thickness can be controlled by adjusting the spraying time or the movement speed of the spraying box 42. This makes it possible to obtain a uniformly thick lining at all angles of spraying.
