Embodiment Construction

[0028] The invention utilizes a clear node concept to construct prefabricated column and beam connections centered on independent steel nodes, and uses steel nodes with higher rigidity and ductility as node load-bearing members to realize rapid and seismic connection of columns and beams, and post-earthquake The repair of locally damaged components is more flexible and convenient, and a new type of prefabricated reinforced concrete frame structure with steel nodes is formed.

[0029] The prefabricated reinforced concrete frame structure with steel nodes includes: prefabricated beam members 2, prefabricated column members 3 and steel nodes. The steel nodes include a first steel node 1a, a second steel node 1b and a third steel node 1c.

[0030] The first steel node 1a includes a steel plate box body 5, and an annular horizontal reinforcing rib 6 and a vertical reinforcing rib plate 7 are arranged in the steel plate box body 5, and upper bearings are respectively arranged on the ...

Abstract

The invention discloses a steel joint precast and assembled reinforced concrete frame structure, which comprises precast beam members, precast column members and joints, wherein each of the nodes comprises a steel plate box in which annular horizontal reinforced rib plates and vertical reinforced rib plates are arranged; the upper and lower surfaces of the steel plate box are respectively provided with an upper force bearing plate and a lower force bearing plate; the outer surface of the steel plate box is provided with rib plates which are respectively connected with the upper and lower force bearing plates; the rib plates are connected with vertical force bearing plates which are respectively connected with the upper and lower force bearing plates; each precast beam member comprises a precast reinforced concrete beam; a beam-end precast steel plate is precast on the end part of the precast reinforced concrete beam, and is connected with a shaped steel beam which is connected with a beam-end force bearing plate; each precast column member comprises a precast reinforced concrete column; a steel plate enclosure box is arranged on the lateral surface of the end part of the precast reinforced concrete column; studs are arranged on the inner lateral surface of the closure box; the end part of the steel plate closure box is provided with a column-end steel force bearing plate; the upper and lower force bearing plates of each joint are respectively with the adjacent columns; and the vertical force bearing plates are connected with adjacent beams.

Description

technical field [0001] The invention discloses a steel node prefabricated and assembled reinforced concrete frame structure used in civil engineering, and belongs to the technical field of civil engineering building structures. Background technique [0002] There are many forms of building structure, among which frame structure is a widely used form of building structure. With the continuous deepening of the concept of environmental protection in society, assembly structures have been considered as a low-carbon and environmentally friendly architectural structure because their components can be produced under control in factories. Prefabricated frame structures currently include steel structures, prefabricated steel frame structures and prefabricated reinforced concrete frame structures. Steel structures have light weight and good ductility, but are expensive and poor in fire resistance. The cost of prefabricated reinforced concrete structures is relatively low, but its st...
