“設計圖經修改後, 原設於大堂底的4顆鏍絲(bolts)將改為6顆. 上鏍絲的深度也由原本的70mm改到45mm.”
On the revised blueprint, the number of bolts originally designed to be drilled upon the bottom of the lobby has been increased from 4 pieces to 6 pieces, and the depth of the drilling has been reduced from the original 70 mm to 45 mm .
“由於須鑽洞的石屎(concrete)內有鋼筋(reinforcements), 鑽洞時須打鈄鑽入, 再用特制的絲冒去更正鏍絲角度”
Since there are steel reinforcements inside the concrete requiring drilling, the holes drilled have to be slanted with angles fixed by specially fabricated bolt heads.
“由於用來安裝瞻薘(canopy)鐵架的石屎牆厚度不一, 第一根steel與最後一根steel安裝後的長度相差了15mm. 解決方法是先將最尾那根steel extend 15mm 與第一根對齊, 然後在它們之間拉一直線, 從而找出其餘落steel的位置和長度, 把它們對齊”
Since there are variances on the thickness of the concrete wall planned for the fabrication of the canopy, the length of the first steel rod and the last steel rod has a difference of 15 mm after assembling.
Solution to this problem is to firstly extend the last steel rod for 15 mm so that it can correspond with the first steel rod. We will then draw a straight line between the first and the last steel rod, so that we can identify the position and length of the remaining steel rods to make sure that they are in precise position and length for the various concrete thicknesses.
