Steel stand column beam

Abstract

The invention discloses a steel stand column beam. The steel stand column beam comprises a steel stand column and a plurality of column beam connecting node components, wherein the plurality of column beam connecting node components are in central symmetry and are uniformly distributed along the outer wall of the steel stand column; each column beam connecting node component comprises a web, an upper flange plate and a lower flange plate; an upper connecting node A is provided with a fixed limiting plate, and a lower connecting node B is provided with a limiting bracket; and the steel stand column beam also comprises a plurality of first clamping plates and a plurality of second clamping plates, and each clamping plate is provided with a high-strength bolt connection pair; the web is connected with a main plate of an H-shaped steel beam through the first clamping plates; the upper flange plate is connected with an upper plate of the H-shaped steel beam through the second clamping plates; a cover plate is arranged on the top end surface of the steel stand column, and a grouting hole and a plurality of vent holes are formed on the cover plate; two flange ring stiffened plates are arranged on the middle part in the steel stand column. By adopting the steel stand column beam, the steel stand column beam technology is more advanced, the process is more complete, safe and applicable, the quality is better guaranteed, the utilization rate of the plate is increased, the energy conservation and consumption reduction can be realized, the environment-friendly requirement can be met, and the component quality and construction quality can be improved.

Description

technical field [0001] The invention relates to the field of building steel structures for high-voltage power transmission, in particular to a steel column and beam. Background technique [0002] At present, the known steel structure, as a main building structure and power steel column structure, has the advantages of being reusable, free of construction waste, green and energy-saving, and material-saving. , Good anti-seismic performance, in line with the sustainable development requirements of my country and the world. In steel structure buildings, beam-column joint connection is the key to steel structure construction. At present, the beam-column joint connection methods of steel structure mainly include welding connection, bolt connection and bolt-welding connection. For the connection of "I"-shaped steel beams and columns, the common method is to directly weld the upper flange plate, web plate and lower flange plate of the "I"-shaped beam and then directly weld with the ...
