Problems solved by technology

Therefore, the use of traditional connection forms for prefabricated structural systems cannot meet the needs of industrialized and efficient installation, and the amount of steel consumed is too large, which is inconsistent with the green building concept advocated by the country. Therefore, the innovation of prefabricated steel structural systems is the next few years. Direction of development

Embodiment Construction

[0040] The technical solution of the present invention will be further described through specific implementation manners below in conjunction with the accompanying drawings.

[0041] The used steel column 5 and steel beam 6 of the steel frame of the present invention are I-beams;

[0042]like figure 1 , figure 2 As shown, the assembled recoverable functional steel frame-support system connected by prestressed joints is composed of assembled joints I1, assembled joints II2, support structure 3 and floor 4, and floor 4 includes type I slab 401 and type II slab 402 Three types of prefabricated concrete slabs are Type III and Type 403.

[0043] like image 3 , Figure 4 , Figure 5 As shown, the fabricated node I1 is a fabricated prestressed column-column splicing node to connect two adjacent steel columns 5 above and below, and is located at the inflection point of the column, which is about 1 / 3 to 1 / 4 of the storey height place; including prestressed tie rod support plate...

Abstract

A fabricated recoverable-function steel frame-supporting system connected by prestressed joints is provided. The fabricated recoverable-function steel frame-supporting system connected by the prestressed joints comprises fabricated joints I, fabricated joints II, supporting structures and floor slabs, the fabricated joints I are fabricated prestressed column-column splicing joints and located in inflection points of columns, and the fabricated joints I comprise prestressed pull rod supporting plates, stiffening plates, half-welded lug plates, web splicing plates and prestressed pull rods; the fabricated joints II are fabricated prestressed beam-beam splicing joints and comprise cantilever beam section flange plates, middle beam section flange plates and rear-tensioning prestressed cables; the supporting structures are arranged between every two vertically adjacent steel beams in pairs, and each pair of the supporting structures comprises supporting rods, supporting rod sleeves, lower end connection pieces and upper end connecting pieces; and the floor slabs comprise three types of prefabricated concrete floor slabs, namely the I-type plate, the II-type plate and the III-type plate. According to the fabricated recoverable-function steel frame-supporting system connected by the prestressed joints, novel prestressed steel beam and steel column splicing joints are adopted, the fabricating efficiency of the structure of the fabricated recoverable-function steel frame-supporting system is improved, rapid construction is achieved, and rapid restoration and rapid rebuilding can be achieved after an earthquake.

Description

technical field [0001] The invention belongs to the field of structural engineering, and specifically relates to an assembled recoverable functional steel frame-support system connected by prestressed nodes, which adopts new prestressed steel beams and steel columns to splice nodes, and can be used after simple repairs after earthquakes. New assembled structure. Background technique [0002] The "Green Building Action Plan" issued by the State Council in January 2013 proposes to promote the industrialization of construction and develop a complete, serialized and standardized green, environmentally friendly, energy-saving and reusable prefabricated structural system. In February 2016, the "Several Opinions of the Central Committee of the Communist Party of China and the State Council on Further Strengthening the Management of Urban Planning and Construction" proposed that in about 10 years, the proportion of prefabricated buildings in new buildings should reach 30%. After th...
