A steel pipe (10) for forming an outer shell is composed of a thin steel plate and is formed into a cylindrical shape by linking a plurality of divided arcuate plates (1) in the circumferential direction via joints (1a, 1b), the plurality of divided arcuate plates being formed by dividing the thin steel plate into a plurality of plates in the circumferential direction and bending the plates at the two circumferential edges to form the joints (1a, 1b).

A nut-holding member used when joining a plurality of substrates having bolt holes by means of a bolt, the nut-holding member comprising: a nut insertion part into which a nut is inserted so as not to rotate with the screwing in of the bolt; a step section that the upper surface of the nut abuts, the upper surface being on the opposite side of the nut from the bearing surface; and a fastening part for holding the nut in a disengagement-preventing state so as to prevent the nut inserted into the nut insertion part from disengaging. The fastening part has a shape that protrudes on the bearing surface side, which is the surface of the nut inserted into the nut insertion part that faces the substrate, or a shape provided with a projection that protrudes on the upper surface side of the nut and hooks on the screw grooves. The fastening part changes shape when the tip of the bolt is screwed into the nut, causing the disengagement-preventing state of the nut to be released.

A steel pipe pile having pile bearing capacity without disturbing the surrounding ground during installation. The steel pipe pile including a first steel pipe pile that has a hollow steel pipe and a first helical fin on the outer periphery thereof from one end toward the other end at a constantly equal pitch; and a second steel pipe pile that has a hollow steel pipe and a helical fin on the outer periphery thereof from one end toward the other end at a constantly equal pitch and that is joined at an end to the other end of the first steel pipe pile, the pitch of the first helical fin and the pitch of the second helical fin being equal, and the first helical fin and second helical fin being continuous along an imaginary helix at the joint between the first steel pipe pile and the second steel pipe pile.

[Problem] To provide a tie member which can be easily connected to support members with reduced work and can be firmly connected to the support members, and a temporary scaffold having the tie member installed therein. [Solution] A strut-equipped tie member comprising a horizontal member and two struts for supporting the horizontal member from obliquely below, and characterized in that engagement means for engaging the horizontal member with the support members are provided to both ends of the horizontal member and that wedge fittings are provided to the lower ends of the struts.

Abrégé

Provided is a joint structure that mechanically joins two tubular steel pipes by fitting together an inner joint pipe and an outer joint pipe that are fixed by welding to corresponding end surfaces of the two pipes, and keeps the two joint pipes together by inserting pins. An outer joint pipe (3) having a plurality of connecting holes (3a...) made in the peripheral wall thereof in the radial direction is fixed by welding to the end surface of one of the tubular steel piles (1). An end mounting bracket (4) is affixed by welding to the corresponding end surface of the other tubular steel pile (2), and to the other side of the end mounting bracket (4) an inner joint pipe (5) having a plurality of connecting holes (4a...) made in the peripheral wall thereof in the radial direction at positions that correspond with the connecting holes (3a) in the outer joint pipe (3) is affixed by welding. The inner joint pipe (5) can fit into the inside of the outer joint pipe (3). The inner joint pipe (5) is inserted into the inside of the outer joint pipe (3), and the connecting holes (3a and 5a) of the outer joint pipe (3) and the inner joint pipe (5) are brought into alignment and a connecting pin (6) is inserted therein, and processing to prevent the pin from being dislodged is performed, connecting the two tubular steel piles (1 and 2).

A fence having no possibility of having local damage even if the fence is repeatedly subjected to a large load such as a wind load and a load due to a collision of an article with the fence, having excellent durability, and normally usable for a long period. Support ropes (3) are horizontally stretched between support pillars (2, 2) vertically installed at an interval. Perforated panels (4) of a square shape are suspended while being connected to each other with their upper sides (4c) positioned parallel to the support ropes (3). Vertical sides (4b) of adjacent end sections of the perforated panels (4) are overlapped with each other. Opposite ends of the upper sides of the perforated panels (4) and the support ropes (3) are connected to each other in a suspension structure in which they are kept in a parallel state.
