Embodiment Construction
[0027] In order to better understand the present invention, the implementation manners of the present invention will be explained in detail below in conjunction with the accompanying drawings.
[0028] Such as figure 1 As shown, an energy-dissipating assembled flange-reinforced-concrete support for roadway support includes arc-shaped flange-reinforced-concrete members (1) and energy-dissipating joints (3); figure 1 , 2 As shown, the hard rubber pressure-bearing body (5) is placed in the middle of the steel casing (2) outside the energy dissipation joint (3), and the metal folded tube (4) is placed symmetrically on both sides, and the metal folded tube (4) and the The hard rubber pressure bearing body (5) abuts, and the metal material used for the metal folded tube (4) should meet the compression ratio when the ultimate pressure is applied (compression ratio = the length of the metal folded tube after ultimate pressure / the metal folded edge before deformation pipe length) i...
