近日，中國建筑工程總(zong)公司所屬中建三局(ju)研(yan)發的科(ke)技(ji)成果“多處大懸(xuan)挑復(fu)雜空間(jian)結構有支撐懸(xuan)伸(shen)推進法施工技(ji)術(shu)”，經北(bei)京市住房和(he)城鄉建設委員會(hui)鑒定達(da)國內領先(xian)水(shui)平。
該(gai)技(ji)(ji)(ji)術(shu)(shu)(shu)(shu)具有以下四大創(chuang)新點：一是(shi)創(chuang)新采用(yong)(yong)(yong)施(shi)工(gong)(gong)順序相關性(xing)控制技(ji)(ji)(ji)術(shu)(shu)(shu)(shu)、臨時支(zhi)撐頂部水平力(li)消除技(ji)(ji)(ji)術(shu)(shu)(shu)(shu)和同步(bu)分級卸載技(ji)(ji)(ji)術(shu)(shu)(shu)(shu)，解(jie)決(jue)(jue)了(le)(le)最大懸挑81米鋼桁(heng)架施(shi)工(gong)(gong)安裝技(ji)(ji)(ji)術(shu)(shu)(shu)(shu)難(nan)題；二是(shi)采用(yong)(yong)(yong)中耳板(ban)加貼板(ban)技(ji)(ji)(ji)術(shu)(shu)(shu)(shu)，采用(yong)(yong)(yong)卡槽節點設計解(jie)決(jue)(jue)了(le)(le)快速定位(wei)難(nan)題；三是(shi)采用(yong)(yong)(yong)“吊柱受力(li)狀(zhuang)態轉換法施(shi)工(gong)(gong)技(ji)(ji)(ji)術(shu)(shu)(shu)(shu)”，解(jie)決(jue)(jue)了(le)(le)按“順序施(shi)工(gong)(gong)法”安裝后吊柱受壓的難(nan)題；四是(shi)應(ying)用(yong)(yong)(yong)焊接機器人及大厚板(ban)仰焊工(gong)(gong)藝方法，減少了(le)(le)焊接工(gong)(gong)作量和殘余(yu)應(ying)力(li)，有利于縮短工(gong)(gong)期(qi)，節約成本(ben)。
