支撐專(zhuān)項(xiàng)方案

一、安裝支撐體系的設(shè)計(jì)與布設(shè)概述高空拼裝支撐體系搭設(shè)由于屋面鋼結(jié)構(gòu)桿件多借點(diǎn)多，施工中隨著鋼構(gòu)件按分區(qū)結(jié)構(gòu)面由主及次的展開(kāi)安裝，臨時(shí)胎架需提前一個(gè)施工區(qū)及時(shí)的進(jìn)行搭設(shè)，為屋面桿件安裝提供臨時(shí)支承和作業(yè)操作平臺(tái)。支撐體系的布置原則1、高空散裝時(shí)，屋面鋼結(jié)構(gòu)主受力桁架首先進(jìn)行安裝，散裝部分主受力桁架需單獨(dú)設(shè)置支撐。2、高空散裝時(shí)，屋面鋼結(jié)構(gòu)的的定位根據(jù)每個(gè)球節(jié)點(diǎn)的坐標(biāo)確定，使整個(gè)屋面的安裝過(guò)程都精確到位，每個(gè)球節(jié)點(diǎn)需設(shè)置支撐，便于施工及定位。3、分片分段吊裝時(shí)，分片需單獨(dú)設(shè)置支撐。4、所有鋼柱下需設(shè)置支撐。5、以保證在安全的基礎(chǔ)上文明施工，避免出現(xiàn)無(wú)必要的安全隱患。根據(jù)節(jié)點(diǎn)的平面坐標(biāo)來(lái)搭設(shè)支撐。6、安裝支撐的設(shè)置還需考慮安裝施工操作、高空焊接施工操作、測(cè)量定位控制施工操作等工序的施工操作要求。安裝支撐體系的分類(lèi)根據(jù)鋼結(jié)構(gòu)及下部土建結(jié)構(gòu)特點(diǎn),屋面鋼結(jié)構(gòu)安裝支撐體系分以下幾種方式:1、主受力桁架下設(shè)置支撐平臺(tái)2、散裝部位設(shè)置支撐架3、分片吊裝設(shè)置格構(gòu)柱支撐4、鋼柱下設(shè)置格構(gòu)柱支撐4種支撐如下圖所示：支撐平臺(tái)支撐架分片格構(gòu)柱支撐鋼柱格構(gòu)柱支撐二、屋面鋼結(jié)構(gòu)安裝支撐體系的布設(shè)2.1屋面鋼結(jié)構(gòu)支撐體系平面布置屋面鋼結(jié)構(gòu)支撐體系布置圖詳見(jiàn)附圖一。各支撐體系設(shè)置位置、標(biāo)高及類(lèi)型等見(jiàn)下表胎架編號(hào)支撐底部標(biāo)高/m支撐頂部標(biāo)高/m胎架咼度/m胎架位置支撐平臺(tái)ZCPT-18.15隨屋面變化約15mW18~W17軸線ZCPT-28.15隨屋面變化約15mW14~W13軸線ZCPT-38.15隨屋面變化約15mW09~W08軸線ZCPT-48.15隨屋面變化約15mW05~W06軸線ZCPT-58.15隨屋面變化約15mW03~W01軸線ZCPT-68.15隨屋面變化約15mE03~E01軸線ZCPT-78.15隨屋面變化約15mE05~E06軸線ZCPT-88.15隨屋面變化約15mE09~E08軸線ZCPT-98.15隨屋面變化約15mE14~E13軸線ZCPT-108.15隨屋面變化約15mE18~E17軸線支撐架ZCJ-18.15隨屋面變化約15mW21~W18軸線ZCJ-28.15隨屋面變化約15mW17~W14軸線ZCJ-38.15隨屋面變化約15mW13~W09軸線ZCJ-48.15隨屋面變化約15mW08~W06軸線ZCJ-58.15隨屋面變化約15mW05~W03軸線ZCJ-68.15隨屋面變化約15mW02~E02軸線ZCJ-78.15隨屋面變化約15mE05~E03軸線ZCJ-88.15隨屋面變化約15mE08~E06軸線ZCJ-98.15隨屋面變化約15mE13~E09軸線ZCJ-108.15隨屋面變化約15mE17~E14軸線ZCJ-118.15隨屋面變化約15mE21~E18軸線屋面天窗格構(gòu)柱支撐（1.75m*1.75m格構(gòu)柱）TCZCT25.0738.1516.923三層樓板梁TCZC-223.6558.1515.505三層樓板梁TCZC-321.7358.1513.585三層樓板梁TCZC-425.5338.1517.383三層樓板梁TCZC-623.6918.1515.541三層樓板梁TCZC-726.9018.1518.751三層樓板梁TCZC-826.9678.1518.817三層樓板梁TCZC-927.6818.1519.531三層樓板梁TCZC-1027.8778.1519.727三層樓板梁TCZC-1129.1978.1521.047三層樓板梁TCZC-1227.758.1519.6三層樓板梁TCZC-1328.8168.1520.666三層樓板梁TCZC-1430.0368.1521.886三層樓板梁TCZC-1531.2278.1523.077三層樓板梁TCZC-1629.7558.1521.605三層樓板梁TCZC-1730.0278.1521.877三層樓板梁TCZC-1831.7488.1523.598三層樓板梁TCZC-1932.1688.1524.018三層樓板梁TCZC-2030.2198.1522.069三層樓板梁TCZC-2130.3418.1522.191三層樓板梁TCZC-2231.7028.1523.552三層樓板梁TCZC-2331.7768.1523.626三層樓板梁TCZC-2430.4358.1522.285三層樓板梁TCZC-2530.6778.1522.527三層樓板梁TCZC-2632.4098.1524.259三層樓板梁TCZC-2732.3078.1524.157三層樓板梁TCZC-2830.5968.1522.446三層樓板梁TCZC-2930.2198.1522.069三層樓板梁TCZC-3031.5018.1523.351三層樓板梁TCZC-3131.1038.1522.953三層樓板梁TCZC-3229.7848.1521.634三層樓板梁TCZC-3329.4878.1521.337三層樓板梁TCZC-3430.7548.1522.604三層樓板梁TCZC-3529.828.1521.67三層樓板梁TCZC-3628.3138.1520.163三層樓板梁TCZC-3729.1978.1521.047三層樓板梁TCZC-3827.0438.1518.893三層樓板梁TCZC-3927.3748.1519.224三層樓板梁TCZC-4026.9258.1518.775三層樓板梁TCZC-4126.3658.1518.215三層樓板梁TCZC-4226.5938.1518.443三層樓板梁TCZC-4326.1218.1517.971三層樓板梁TCZC-4425.8478.1517.697三層樓板梁TCZC-4525.0728.1516.922三層樓板梁TCZC-4624.498.1516.34三層樓板梁TCZC-4726.0838.1517.933三層樓板梁TCZC-4825.768.1517.61三層樓板梁屋面分片格構(gòu)柱支撐（1.75m*1.75m格構(gòu)柱）WMZC-124.0058.1515.855三層樓板梁WMZC-228.5698.1520.419三層樓板梁WMZC-322.136-0.222.336基礎(chǔ)面WMZC-414.715-0.214.915基礎(chǔ)面WMZC-530.947-0.231.147基礎(chǔ)面WMZC-632.313-0.232.513基礎(chǔ)面WMZC-731.551-0.231.751基礎(chǔ)面WMZC-828.456-0.228.656基礎(chǔ)面WMZC-933.605-0.233.805基礎(chǔ)面WMZC-1033.99-0.234.19基礎(chǔ)面WMZC-1133.985-0.234.185基礎(chǔ)面WMZC-1233.331-0.233.531基礎(chǔ)面WMZC-1333.988-0.234.188基礎(chǔ)面WMZC-1433.606-0.233.806基礎(chǔ)面WMZC-1533.372-0.233.572基礎(chǔ)面WMZC-1633.969-0.234.169基礎(chǔ)面WMZC-1732.347-0.232.547基礎(chǔ)面WMZC-1830.984-0.231.184基礎(chǔ)面WMZC-1929.452-0.229.652基礎(chǔ)面WMZC-2031.41-0.231.61基礎(chǔ)面WMZC-2127.4828.1519.332三層樓板梁WMZC-2223.5228.1515.372三層樓板梁WMZC-2314.616-0.214.816基礎(chǔ)面WMZC-2422.182-0.222.382基礎(chǔ)面拱格構(gòu)柱支撐（2m*2m格構(gòu)柱）GZC-127.53-0.227.73基礎(chǔ)面GZC-222.34-0.222.54基礎(chǔ)面GZC-335.537-0.235.737基礎(chǔ)面GZC-434.001-0.234.201基礎(chǔ)面GZC-539.141-0.239.341基礎(chǔ)面GZC-638.967-0.239.167基礎(chǔ)面GZC-740.354-0.240.554基礎(chǔ)面GZC-840.178-0.240.378基礎(chǔ)面GZC-939.145-0.239.345基礎(chǔ)面GZC-1038.972-0.239.172基礎(chǔ)面GZC-1135.537-0.235.737基礎(chǔ)面GZC-1234.137-0.234.337基礎(chǔ)面鋼柱格構(gòu)柱支撐（1.75m*1.75m格構(gòu)柱）941613.8648.155.714三層樓板梁941713.8648.155.714三層樓板梁941814.0278.155.877轉(zhuǎn)換梁941914.0278.155.877轉(zhuǎn)換梁942315.8688.157.718三層樓板梁942516.1098.157.959三層樓板梁942616.1098.157.959三層樓板梁942716.2048.15&054三層樓板梁942816.2048.15&054三層樓板梁942916.2858.15&135三層樓板梁943016.2858.15&135三層樓板梁943116.478.158.32三層樓板梁943216.478.158.32三層樓板梁943316.6138.158.463三層樓板梁943416.6138.158.463三層樓板梁943516.9398.15&789三層樓板梁943616.9398.15&789三層樓板梁943717.1068.158.956三層樓板梁943817.1068.158.956轉(zhuǎn)換梁948430.1228.1521.972三層樓板梁948530.7428.1522.592轉(zhuǎn)換梁948630.7428.1522.592轉(zhuǎn)換梁948730.9568.1522.806三層樓板梁948830.9568.1522.806三層樓板梁948931.2538.1523.103轉(zhuǎn)換梁949031.2538.1523.103轉(zhuǎn)換梁943917.8138.159.663三層樓板梁944017.8138.159.663三層樓板梁944118.028.159.87三層樓板梁944218.028.159.87三層樓板梁944318.38.1510.15三層樓板梁944418.4578.1510.307三層樓板梁944518.4578.1510.307三層樓板梁944618.8248.1510.674三層樓板梁944718.8248.1510.674三層樓板梁944818.8868.1510.736三層樓板梁
