【正文】 howed great use also brings great convenience to the staff. Precisely because of this robot to get people39。s attention began to be a high degree of development. Labor rates, working conditions, labor intensive aspects of promoting development. Both at home and abroad to develop the PLC (programmable logic controller) is in various special circumstances and under special conditions set for mechanical devices. Now turned on the development of the microelectronics automatic control technology and the rapid development of the trains, the success of PLC hardware software and simulation control win big and successful development, now continues to develop as a factory automation standards. Because robots are good development of the technology makes a good optimization of productive capital, and robot shows this unique advantages, such as: has good patibility, wide availability, hardware is plete, and programming that can be mastered in a short time, so in the context of industrial PLC applications became ubiquitous. Manipulator in many developed country agriculture and industry has been applied, such as the use of mechanical harvesting large areas of farmland, repeated operations on the highspeed line that uses a robotic arm, and so on. Today, the high level of automation bined with restrictions on the manipulator development level is slightly lower than the international. The design is mainly arm welding machine by PLC Automation control. This of design let designers on in school by learn of has a must of consolidation, understand has some usually didn39。二、工程概況工程名稱*******樓工程地址煙臺市濱海中路建設(shè)單位********置業(yè)有限公司設(shè)計單位*********勘察單位***********監(jiān)理單位******監(jiān)理公司監(jiān)督單位***********建筑工程質(zhì)量監(jiān)督站施工單位*******工程總承包有限公司合同工期總工期395日歷天，開工日期*******竣工日期********結(jié)構(gòu)類型框架剪力墻三、塔吊選型、定位及結(jié)構(gòu)處理塔吊選型根據(jù)建筑物的總高、建筑物外形尺寸、主體結(jié)構(gòu)大模板施工的需要，本工程選用一臺QTZ80C型液壓自升附著式起重機(jī)（山東華夏集團(tuán)生產(chǎn)），用作主體結(jié)構(gòu)施工期間垂直運輸?shù)墓ぞ摺Ｋ醵ㄎ粸闈M足塔吊的安裝要求及使用要求，塔吊基礎(chǔ)設(shè)置在520軸東側(cè)的5P和5J 軸間，具體位置見附圖一(塔吊基礎(chǔ)平面位置圖)。結(jié)構(gòu)處理根據(jù)塔吊的定位，塔身座落在基礎(chǔ)底板上。具體做法如下：1）塔吊基礎(chǔ)頂標(biāo)高與基礎(chǔ)頂標(biāo)高一致，將塔吊基礎(chǔ)范圍內(nèi)的32和35樁承臺及基礎(chǔ)底板與塔吊基礎(chǔ)一起施工；2）施工前先按照設(shè)計要求做好該部位的防水層，并予留300mm長以便與整個基礎(chǔ)底板防水層的搭接連接；3）在塔吊基礎(chǔ)周邊,基礎(chǔ)底板厚度中間位置設(shè)3mm厚、350mm寬止水鋼板(詳見附圖二)，同時按要求予留底板鋼筋以便與整個基礎(chǔ)底板的連接。四、塔吊基礎(chǔ)施工塔吊基礎(chǔ)型號的確定根據(jù)地質(zhì)勘察資料及現(xiàn)場實際土層情況，塔吊基礎(chǔ)座落在粉質(zhì)粘土層上，其地耐力為190Kpa，符合地耐力為170Kpa的基礎(chǔ)圖要求，故塔吊基礎(chǔ)按塔吊說明書b型砼基礎(chǔ)圖要求施工。塔吊基礎(chǔ)施工根據(jù)塔吊基礎(chǔ)圖及基礎(chǔ)結(jié)構(gòu)施工圖，確定塔吊基礎(chǔ)外形尺寸為長寬高= 550055001350 ，砼強度等級為C,基礎(chǔ)配筋詳見附圖三，鋼筋使用前必須經(jīng)檢驗合格。砼采用商品砼（，塌落度120）內(nèi)摻5%早強劑。在砼澆筑過程中經(jīng)監(jiān)理見證取樣留設(shè)試塊2組，一組為標(biāo)養(yǎng)、一組為同條件養(yǎng)護(hù)試塊。澆筑時，用水準(zhǔn)儀及時控制底架四角的水平度。塔機(jī)組裝1）安裝底架：將底架放置于基礎(chǔ)平臺上，裝上壓板，擰緊地腳螺栓。若超差則在底盤下加鋼板墊塊，墊塊應(yīng)墊實、墊牢，擰緊20M39地腳螺栓（雙螺母防松）。3）安裝回轉(zhuǎn)支承總成將回轉(zhuǎn)支承總成吊裝到套架上，對正下支座上四根主弦桿與標(biāo)準(zhǔn)節(jié)上的企口，用銷軸與套架連接起來，并用8只M363320的標(biāo)準(zhǔn)節(jié)螺栓將下支座與標(biāo)準(zhǔn)節(jié)連接，然后安裝上支座的工作平臺。調(diào)整16只爬升導(dǎo)輪與塔身主弦桿之間的間隙23mm，此工作應(yīng)在安裝塔頂之前進(jìn)行。吊裝
