Definitions

  • the flank 21 is a member for transmitting the earth pressure acting on the retaining wall 20 to the beam 22, and the kerf 22 supports the earth pressure transmitted from the mountain retaining wall 20 via the erection 21 with a compressive force.
  • H-shaped steel which is relatively easy to obtain, is commonly used.
  • a cut beam made of a square steel pipe can be set to have a long buckling length, but because of its cross-sectional shape, it is difficult to provide joints at the ends and side portions, making it difficult to join the belly and attach the fire beam. There was a problem.
  • the present invention has been made in order to solve the above-mentioned problems, and it has been possible to secure a wide working space by increasing the buckling length, and to enable joining to the abdomen and attachment of a fire beam.
  • An object of the present invention is to provide a beam device and a mountain retaining work constructed using the beam device.
  • Square steel pipes do not have a strong or weak axis in terms of cross-sectional performance like H-section steel, so the buckling length can be increased, thereby significantly reducing the amount of steel used for fired beams and shelf piles. Can do. In addition, even if a fire beam is installed, it will not hinder the carrying in and out of materials and equipment from above.
  • the length adjusting member 6 is an axial direction of the protuberance 2 from two joining flanges 6a, 6a installed in parallel to the axis perpendicular direction of the beam main body 3a and a web 6b installed between the joining flanges 6a, 6a. As shown in FIG. A plurality of bolt holes 6c are formed in the joining flanges 6a and 6a.
  • the universal joint 13 includes a pair of receiving pieces 13a and 13b attached to the joint metal 5 and the length adjusting member 6, respectively, and a rotating piece 14 attached between the receiving piece 13a and the receiving piece 13b. Yes.
  • the rotating portion 14a of the rotating piece 14 freely rotates around the rotating pin 15a in the guide recess 13d of the receiving piece 13a, so that the cut beam 3 can be arbitrarily aligned in the horizontal direction on the side surface portion of the protuberance 2 Can be joined obliquely in the direction.
