BIM動態
測量放線神器——BIM放樣機器人
發布日期:2016-8-24  瀏覽次數:5572 [返回上一頁]

深圳華潤城萬象天地工程以其單體78.9萬方體量,躍居萬象系列之首,作為華潤置地萬象系列深耕十余年新作,其具有機電系統眾多,管線錯綜復雜,空間結構繁復多變,業態豐富多樣等特點。而華潤建筑從深圳萬象城伊始,一路走來,在機電系統安裝質量方面,對品質控制也提出了更高的要求。


相較于傳統機電管線施工,借助CAD圖紙使用卷尺等工具純人工現場放樣的方式,存在放樣誤差大、無法保證施工精度,且工效低,F項目引進了BIM放樣機器人──天寶全站儀,利用其快速、精準、智能、操作簡便、勞動力需求少的優勢,將BIM模型中的數據直接轉化為現場的精準點位。目前,華潤建筑機電總包已在T6塔樓區域進行了現場支吊架精準放樣,初步取得了良好的效果。本期,小編就天寶全站儀精確測量及放樣技術原理給大家作簡要介紹。


▲ 紅外激光放樣標記


一、主要硬件包括:

1.全站儀主機:用于指示、測量放樣點位的設備,其放大倍率:32倍;測角精度:2秒;測距精度:1mm;高速測距精度:2mm。



2.外業平板電腦:即手持終端,導入BIM模型后,用于控制、選擇測量或放樣點,可直觀連接和設置全站儀。



3.三腳架:支撐及固定全站儀主機,可根據需要調整高度及角度。



4.全反射棱鏡及棱鏡桿:用于點位在地面上測量及放樣,與主機智能連接后準確定位,實時動態跟蹤。



二、主要軟件包括:

1. Trimble Field Link軟件:連接內業到外業(BIM到現場);可視化放樣、采集現場數據、計算誤差、輸出工作報告、拍攝實時視頻等。



2.基于REVIT及CAD的測量及放樣點位插件:把點位在模型中選取并設置完成,導出到Trimble Field Link軟件,操作軟件可指揮機器人現場放樣。



三、工作原理:

1)從BIM模型中設置現場控制點坐標和建筑物結構點坐標分量作為BIM模型復合對比依據,在BIM模型中創建放樣控制點。


2)在已通過審批的機電BIM模型中,設置機電管線支吊架點位布置,并將所有的放樣點導入Trimble Field Link軟件中。


3)進入現場,使用BIM放樣機器人對現場放樣控制點進行數據采集,即刻定位放樣機器人的現場坐標。


4)通過平板電腦選取BIM模型中所需放樣點,指揮機器人發射紅外激光自動照準現實點位,實現“所見點即所得”,從而將BIM模型精確的反應到施工現場。



以深圳(大涌)萬象天地機電施工總承包工程施工為契機,針對天寶全站儀放樣機器人從前期準備、現場放樣、管線安裝等環節介紹其工作流程及快速、精準、智能、高效率的技術優勢。


天寶機器人放樣流程

下圖所示為天寶機器人放樣指導施工流程,包括六個主要步驟,綜合管線BIM優化為整個流程順利實施的前提,天寶機器人通過三四個簡單、快捷的步驟迅速確定點位,為各專業同時提供工作面,標準統一,界面清晰,不再是傳統的各自為政,交叉雜糅。

放樣施工步驟詳解

1)將機電綜合管線模型按排布原則、凈空要求、深化標準等進行優化,各專業工程師共同審核后確定綜合管線圖。

▲ T6標準層綜合管線圖


2)結合主體結構實體,選取易于標記測量的結構軸線上某點為基準點,預先排布管線支吊架點位,細化關鍵復雜區域點位,最后生成數據點。

3)主體結構測量師在指定軸線處標定建筑一米線,然后在指定位置布設基準點。


▲ 基準點布置圖


4)根據現場基準點和放樣點的位置,選定天寶機器人架設位置,使其測設較多點位,通過對基準點聚焦計算出儀器在空間的位置及與放樣點的距離。


▲ 機器人建站定位


5)依據步驟4中獲得的位置和距離,對紅外線所及區域逐一描點定位。放樣完成后選取兩個復雜區域復測校核。

▲ 標記好的點位


6)各專業施工隊遵守施工順序,按各自點位可在同一工作面同時施工,避免其他專業干擾,管線可大量預制,保證一次成活達標。


▲ 各專業工人施工


工效對比

根據T6標準層所有支吊架安裝完成所用工時進行統計,與采用傳統方式各專業自己邊測量邊安裝比較,總減少三十余工時,降低勞力成本逾40%,天寶機器人放樣指導施工的優勢顯而易見,我司將持續推進其與BIM技術的融合,使其在各項目廣泛應用。
