Connecting joint structure of continuous box type crane beam and lattice type column

Abstract

The invention discloses a connecting joint structure of a continuous box type crane beam and a lattice type column. The connecting joint structure comprises the continuous box type crane beam and the lattice type column, wherein the continuous box type crane beam is of a box type beam structure defined by an upper flange plate, a lower flange plate, a first web and a second web; the lattice type column comprises an upper column body and a shoulder beam body which are connected up and down; the upper flange plate and the lower flange plate are provided with an upper through hole and a lower through hole correspondingly; the upper end of the upper column body sequentially penetrates the lower through hole and the upper through hole; a support is fixedly arranged at the bottom of the lower flange plate and supported on the shoulder beam body; a supporting plate is fixedly arranged on the shoulder beam body and located on the side portion of the support; and the top of the upper column body is fixedly connected with the upper flange plate through an upper fixing assembly, the upper fixing assembly can cover the upper through hole, the bottom of the upper column body is fixedly connected with the lower flange plate through a lower fixing assembly, and the supporting plate and the lower flange plate are connected through a plurality of first fasteners. According to the connecting joint structure, connection of the continuous box type crane beam and the lattice type column can be convenient, the construction difficulty is lowered, and the construction period is shorter.

Description

technical field [0001] The invention relates to the technical field of building steel structures, in particular to a connection node structure between a continuous box crane girder and a lattice column. Background technique [0002] The crane beam is a beam structure that supports the operation of the bridge crane. There are crane tracks on the beam, and the crane travels back and forth on the crane beam through the rails. Most of the crane girders are supported on lattice columns, and the lattice columns include upper columns, shoulder beams and lower columns sequentially connected from top to bottom. Existing steel structure crane girders generally adopt I-shaped beams, and some use box-shaped beams. During installation, the two ends of the crane girder adopt a simply supported structure, and the structural form is that the two ends of the crane girder are supported on the shoulder beam of the lattice column through the flange support or the flat support, and then are fix...
