26、iyof wl. Hisoryha5965 kN/m。25t汽車(chē)吊其基本臂長(zhǎng)16.5m ,最大臂長(zhǎng)61m。最大基本臂 最大起重力矩為9526 kN/m ,最大最長(zhǎng)主臂最大起重力矩為4675 kN/m。本標(biāo)段所架設(shè)最大梁長(zhǎng)為21.5m空心板梁,最大粱重為37.2t。吊裝就位時(shí),作業(yè)半徑最大為8m,最大起重重量為48.9t, 起重機(jī)完全符合要求。2、起吊鋼絲繩的選用根據(jù)所選鋼絲繩為66mm, 67+1驗(yàn)算:最大起吊重量 37.2t,設(shè)起吊點(diǎn)二個(gè),采用二根鋼絲繩作業(yè),每個(gè)吊點(diǎn)鋼絲繩 受力為25%,考慮吊點(diǎn)受力不均,現(xiàn)每個(gè)吊點(diǎn)鋼絲繩受力按 35% 考慮,即 Fmax=37.2 M5%=13.02t=1

27、30.2kN。根據(jù)鋼絲繩的計(jì)算要求,最小破斷拉力總合=2270 kN X1.249 (鋼絲繩為呢絨芯的系數(shù))=2835KN 。安全系數(shù):f=2835/130.2=21.77 >f=5,所選鋼絲繩適用。3、運(yùn)梁炮車(chē)為了減少吊車(chē)移位,配備四臺(tái)運(yùn)輸空心板梁的炮車(chē)。 炮車(chē)選 用進(jìn)口三菱車(chē),型號(hào)為 FV414 ,馬力440匹,主車(chē)三軸10胎, 后拖架車(chē)雙聯(lián)四軸16胎。五、施工程序和方法:5.1、 施工程序圖5-1空心板梁架設(shè)施工工序圖5.2、 吊裝順序、方法及措施1、吊裝順序從內(nèi)邊梁開(kāi)始至外邊梁進(jìn)行吊裝, 這樣有利于施工方案完善 和提高安全系數(shù)。2、梁板梁場(chǎng)吊裝及加固預(yù)制梁預(yù)制、壓漿、封錨完成后,
