Description

Positioning device convenient to position and install cross beam

Technical Field

The utility model relates to the technical field of steel structure positioning, in particular to a positioning device convenient for positioning and mounting a cross beam.

Background

The steel has high strength and high elastic modulus, and compared with concrete and wood, the steel has relatively low ratio of density to yield strength, so that the steel structure has small cross section, light dead weight, convenient transportation and installation and is suitable for structures with large span, high height and heavy load, and the steel structure is a structure composed of steel materials and is one of main building structure types.

The connection of steel column and girder steel is very important a ring in the steel construction, bolted connection has the advantage that the connection is firm, the installation is dismantled conveniently, current steel column and girder steel connecting method is generally that girder steel terminal surface offsets with a side of steel column, then the terminal surface and the steel column side of girder steel are passed in proper order to the bolt and girder steel and steel column fixed connection, the drawback of this kind of connected mode is that the bolt need bear very big longitudinal shear, therefore to the quantity of bolt still the mounted position of bolt must be very studied, otherwise the reliability of connection will become low, the bolt receives the shearing force and the bending deformation even fracture's condition appears, and then influence the holistic firm of steel construction.
