Prefabricated frame adopting combination of steel reinforced concrete columns and steel beams

Abstract

The invention provides a prefabricated assembled frame adopting a combination of steel concrete columns and steel beams, including several bottom column units, several middle column units, several top column units and several beams, all of which are prefabricated components. The upper end of the bottom column unit is provided with an upper column joint. The upper and lower ends of the middle column unit are respectively provided with an upper column joint and a lower column joint, and its middle part is provided with a beam-column connecting node. The lower end of the column unit on the top floor is provided with a lower column joint, and its upper end is a column connection node. Both ends of the beam are provided with beam joints. These components are assembled on site, avoiding the complicated process of traditional construction in the node area, and only need to assemble column joints and beam joints outside the node area, thus greatly improving construction efficiency and engineering quality.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a prefabricated assembly frame that adopts a combination of steel concrete columns and steel beams. Background technique [0002] The prefabricated structure decomposes the structure into a number of independent component units (such as beams, columns, walls, panels, etc.), each unit is preset in the factory, and connected by a special connection method on site to form a whole. The prefabricated structure has the characteristics of energy saving, environmental protection, fast construction speed and high construction precision. At present, research on the form of prefabricated structures and on-site connection methods has become the most dynamic direction. [0003] Prefabricated frame is one of the most commonly used forms of prefabricated structures. Traditional prefabricated frames mostly use reinforced concrete beams and columns, and the joints of beams and c...

Problems solved by technology

[0004] ①Reinforced concrete has low strength, large cross-section and heavy weight, which brings a lot of inconvenience to prefabrication, transportation, hoisting and assembly;

[0005] ②The internal force at the beam-column joint is relatively large, the stress situation is complicated, there are many steel bars in the joint area, the construction of on-site steel bar binding and concrete pouring is difficult, the construction quality is unstable, and it is difficult to ach
