    Abstract: PROBLEM TO BE SOLVED: To provide a screw type reinforcement joint for a deformed bar, which facilitates formation of a male screw part of a reinforcement end, and which is excellent in productivity and strength of the male screw part.SOLUTION: A pair of reinforcements 1 and 1 formed as deformed bars is connected together by means of a male screw part 1c and a screw cylinder 2, which are provided at ends thereof. In each reinforcement 1, a protrusive streak 1b of an outer peripheral surface is molded by roll molding of an iron wire rod serving as a material, and a diameter-enlarged part set larger in diameter than other parts is molded in a part in a length direction. An outside diameter of the diameter-enlarged part is set equal to/smaller than the outermost reinforcement diameter D1, including a dimension of the protrusive streak 1a, of the reinforcement 1. The male screw part 1c is formed on the diameter-enlarged part by rolling.

    Abstract: PROBLEM TO BE SOLVED: To provide an anchor simple in design and capable of largely reducing manufacturing cost. SOLUTION: This 2-compartment anchor for fixing a device (having a fastener) to a structure comprises a first compartment having a first bore similar to that of a nut adopted to form a mechanical interlock with the fastener and a second sled-like bore. A second compartment fixes the first compartment to the structure. The second compartment comprises a first sled-like portion capable of being fixed to the first compartment by the mechanical interlock with the second bore and a second sled-like portion for fixing the second compartment to the structure. The first and second bores can have first and second diameters. The first diameter is larger than the second diameter. A screw is a tapping screw. COPYRIGHT: (C)2004,JPO
