A kind of huge rock floor-engaging frame structure, it includes have a support frame； Most adjustment position-limiting units in conjunction with support frame activity respectively； And one winding what respectively adjust and tighten unit on position-limiting unit. Thereby, support frame can be fixed in what plant hole, and plant soil ball is fixed with the cooperation for tightening unit using adjustment position-limiting unit, Hou again will plant the raw-soil backfill what plant hole in, and then root system of plant structure can be imitated, expand the drag area of soil ball, and make root system of plant plane prolong it is raw be not required in depth lower section, and reach lightweight, the effect of easy what operates with, unrestricted what planting location, fixed force are good and does not limit plant future growth.一種磐地支架結構，其包含有一支撐架；多數分別與支撐架活動結合之調整限位單元；以及一繞設於各調整限位單元上之束緊單元。藉此，可將支撐架固定於植穴中，並利用調整限位單元與束緊單元之配合將植物土球加以固定，之後再將植生土回填於植穴中，進而可模仿植物根系結構，擴大土球之抗力面積，且使植物根系平面延生不需深入地下方，而達到輕量化、易於操作使用、不受限於種植位置、固定力佳以及不限制植物未來成長之功效。
