ay to pick out the two stars shining bright on either side of the Milky Way, that is, if people even know on which day Qixi falls. There are ready reminders dotted about, in the form of big ads saying Sales on Chinese Valentine39。 混凝土運輸方案的審核:由于每棟樓的斜屋面面積較大,混凝土一次澆筑量多的達 200多 m3,而斜屋面尖角又是不規(guī)則連接,直接采用泵送,擺管搭設施工困難,且施工速度慢;若只用塔吊進行吊送,由于樓屋高,澆筑時間過長( 2h才 6~8m3),且容易出現(xiàn)大量施工縫;故監(jiān)理審核同意采用泵送至屋頂特定操作平臺再轉(zhuǎn)塔吊施工方案,既使施工方便又提高施工速度。 為防止雙層鋼筋被踩陷及鋼筋綁扎原因造成滲水情況的出現(xiàn),應采取以下監(jiān)控措施: ( 1)為了避免在澆搗混凝土過程中板面鋼筋下陷,保證板筋的有效高度,在雙層鋼筋網(wǎng)之間要求增設有效的支撐馬登筋,支撐馬登筋不小 于 Φ 10,當板筋≧ Φ 12時,間距不大于 10001000mm,當板筋 Φ 12時,間距不大于 600600mm,同一方向上的支撐不少于 2道,且距板筋末端不大于 150mm。專業(yè)監(jiān)理工程師事前還應對模板,木方、鋼管、扣件等進行現(xiàn)場抽檢,存在缺陷的材料嚴禁使用。 2 坡屋面質(zhì)量監(jiān)控的重點、難點及建議 基礎和主體的施工工藝和別的框剪結(jié)構(gòu)房屋的施工工藝并無多大區(qū)別,其質(zhì)量監(jiān)控重點在坡屋面的施工上,坡屋面施工周期在整個施工周期上占很大的比重,從高程控制到抄平放線,從模板的支撐系統(tǒng)到模版的拼架,從鋼筋的加工到鋼筋的綁扎以及混凝土的澆筑順序等均體現(xiàn)了這一特點,再加上此類斜屋面形式較為復雜,坡度較陡,其模板支撐結(jié)構(gòu)、模 板構(gòu)造和安裝、混凝土施工控制等幾個大方面,就成為監(jiān)理控制的重點和難點。 ( 4)因屋面的坡度較大,操作人員根本無法在屋面雙層鋼筋網(wǎng)上站穩(wěn),為了保證操作人員的安全,監(jiān)理要檢查操作人員是否系好安全帶,安全帶系在屋脊處專門設置的鋼筋彎鉤上,當完成一處時,再換系在相鄰的鋼筋彎鉤上。在屋面與頂層樓面間搭設 1條 600mm寬的斜道,上釘防滑條,確保施工通道安全。重點 對進行材料的完好性和方案要求的一致性進行把關(guān)。 【關(guān)鍵詞】 模板支撐 鋼筋綁扎 混凝土澆筑 控制要點 目 錄 1 、難點及建議 1 1 1 2 2 2 2 2 2 2 2 3 ,監(jiān)理及時采取有效的控制措施 3 3 3 3 3 4 ,監(jiān)理做好旁站工作 4 4 4 4 1 工程概況 南京天華硅谷小區(qū)建筑為西班牙建筑風格,建筑面積共 60萬 ㎡,由 52巾童小高層及 9巾童高層組成,每巾童一般分二至四個單元不等,每個單元為一梯二戶,其頂層屋面采用坡平結(jié)合的形式,單室頂為四坡形式,每戶坡頂組合有“ L”型、“ T”型、“十”型及異型等,;另局部平頂功能主要為放置太陽能熱水器。 審核模板支撐專項方案,由于頂層屋脊點高度最高達 ,所以需重點對支撐方案進行技術(shù)審查。 屋面結(jié)構(gòu)坡度較陡,為了施工安全,監(jiān)理人員應要求施工單位,在坡屋面施工前完成頂層周邊的安全防護和搭設好工作人員上下安全防護通道工作。 5 坡屋面混凝土澆筑過程監(jiān)理控制要點 審核混凝土澆筑施工專項方案。 6 總語 通過監(jiān)理機構(gòu)對坡屋面專項方案的審查、材料的把關(guān)、施工過程的跟蹤旁站檢 查和控制、以及坡屋面混凝土順利澆筑,混凝土觀感質(zhì)量良好,技術(shù)指標均符合設計和規(guī)范要求。方案中坡屋面板底模采用厚 12mm高強竹膠合板;底模支撐搭設滿堂腳手架,支撐系統(tǒng)采用 Φ 48,脊梁立柱排距 600mm,斜板立柱排距 900mm900mm,全部鋼管支撐水平設鋼管拉桿,底部設掃地桿,上墊 10050mm的木方;為確保底模的穩(wěn)固,在緊靠現(xiàn)澆屋面板底模沿屋面坡度方向加設橫桿一道,以使支撐系統(tǒng)形成井字架結(jié)構(gòu)。 4 坡屋面鋼筋安裝工程監(jiān)理控制要點 審查鋼筋安裝施工專項方案。 由于屋面現(xiàn)澆混凝土的工程量較大,而且屋面坡度較大 、施工場地受到限制,不可能進行大面積澆筑。 致 謝 在這次畢業(yè)論文寫作過程中,南京廣播電視大學各位老師給予大力支持,也得到了相關(guān)老師的精心指導,在此一并表 示衷心的感謝! 參考文獻: [1]《 2021年最新建筑屋面工程施工技術(shù)標準與質(zhì)量驗收規(guī)范實用手冊》中國科技文化出版社出版 [2]《屋面工程質(zhì)量驗收規(guī)范》 GB50207— 2021 [3]《混凝土結(jié)構(gòu)施工規(guī)范》 GB50010— 2021 [4]《混凝土結(jié)構(gòu)工程施工質(zhì)量驗收規(guī)范》 GB50204— 2021 請您刪除一下內(nèi)容, O(∩ _∩ )O 謝謝?。?!Many people have the same mixed feelings when planning a trip during Golden Week.

However, it can also be the easiest way to ruin how you feel about a place and you may bee more fatigued after the holiday, due to battling the large crowds. During peak season, a dream about a place can turn to nightmare without careful planning, especially if you travel with children and older people. As most Chinese people will take the holiday to visit domestic tourist destinations, crowds and busy traffic are inevitable at most places. Also to be expected are increasing transport and acmodation prices, with the possibility that there will be no rooms available.

You cannot miss out the Autumn of Arxan. It is definitely the best with brightlycolored scenery full of emotions. Autumn in the northern part of the country es earlier than the South. A September rain followed by the footprints of Autumn brings more colors to the once emerald green mountain and blooming grassland. Shutterbugs flock to see for themselves the marvel of splendid colors around the mountains and waters, many of whom have travel a long distance and even camp here only to capture a moment of the nature wonder. The silver birch turns golden, while the larch is still proudly green. You will find yourself drowned in the intoxicating red of the wild fruits as well as the glamour of flowers in full blown.
