Rail movable type prefabricated beam steel pedestal

Abstract

The invention discloses a rail movable type prefabricated beam steel pedestal. The pedestal comprises a main steel beam and a foundation trench, and the main steel beam is composed of a plurality of sets of bottom die support platforms, a plurality of pieces of supporting I-steel and a lower steel platform; steel bottom dies are installed at the upper end of the bottom die support platforms correspondingly, driving wheel sets are installed on the two sides of the middle of the lower surface of the lower steel platform respectively, driven wheel sets are installed on the two sides of the lowersurface of the lower steel platform respectively, and two movable supporting legs are installed at the two ends of the lower surface of the lower steel platform respectively; two basic rails are installed in the foundation trench; and a switchboard is movably installed at the end part of the other side of the lower end of the main steel beam, and buffering devices are installed at the end parts ofthe two ends of the main steel beam. According to the prefabricated beam steel pedestal, safe construction and smooth and safe transferring can be provided for construction units, in the transferringprocess, rapid installation and repeated use can be achieved, the productivity is greatly improved, and benefits are created for construction enterprises.

Description

technical field [0001] The invention relates to the technical field of road and bridge construction, in particular to a rail-movable prefabricated beam steel pedestal. Background technique [0002] At present, during the construction of roads, expressways and key projects in my country, prefabricated T-beams, box girders, and hollow slab girders generally use fixed concrete pedestals and a small part of fixed steel pedestals. Prefabricated T-beams, box girders, hollow slab beams, fixed concrete pedestals and a small number of fixed steel pedestals mainly occupy a large area; when prefabricating beams, binding steel bars and assembling formwork, mobile work efficiency is low and cross-operation safety risks are high; fixed concrete pedestals cannot Transportation is used for a project or construction site, and it can only be destroyed on the spot after the project is completed, resulting in high social costs and waste of resources; fixed concrete pedestals cannot be fully app...
