Support structure for stand column and dual cantilever beams in any combination and use method thereof

Abstract

The invention relates to a support structure for a stand column and dual cantilever beams in any combination and a use method of the support structure. The support structure comprises a steel tubular column and dual cantilever beams, wherein a plurality of layers of force bearing rings are arranged on the outer side of the steel tubular column at intervals, a plurality of first reinforcing plates are arranged between the lower side surfaces of the force bearing rings and the outer wall surface of the steel tubular column; the dual cantilever beams include a left half cantilever beam and a right half cantilever beam which are mutually symmetric, arc grooves matched with the outer side of the steel tubular column are arranged in the spliced surfaces of the left half cantilever beam and the right half cantilever beam, the arc grooves are internally provided with force transmission ring sections matched with the force bearing rings, a plurality of second reinforcing plates are arranged between the upper side surfaces of the force transmission ring sections and the inner walls of the arc grooves, the left half cantilever beam and the right half cantilever beam are provided with arc straps for tightly banding the left half cantilever beam and the right half cantilever beam on the steel tubular column, connection end plates are vertically arranged at the two ends of the arc straps, and each connection end plate is provided with a first connection hole for allowing a first connection bolt to pass through. The support structure is large in born force and can be used repeatedly and flexibly.

Description

technical field [0001] The invention relates to a support structure in the field of construction, in particular to a support structure with arbitrarily combined columns and double cantilever beams and its application method. The present invention is applicable to the flexible support project of the vertical column supported underground or the temporary erected support column. Background technique [0002] Usually, the connection nodes of the column and the beam are determined by a certain structural design, and the spatial position of the beam installed on the column is specifically set. However, in similar application environments such as internal support of underground support engineering, the columns must be preloaded into the soil before excavation, because the position of the joints is difficult to locate accurately, so the structure of beams and columns is difficult to use tool-type installation. Only the method of excavating the earthwork first and then welding in se...
