檢查井模具以鋼模為主,面板主材選用Q235鋼板,支撐結構可選型鋼或者鋼板,規格可根據模具形式選擇,應滿足以下要求:
1.模具應具有足夠的承載力、剛度和穩定性,保證在構件生產時能可靠承受澆筑混凝土的重量、側壓力及工作荷載。
2.模具應組裝、拆模方便,且應便于鋼筋安裝和混凝土澆筑、養護。
3.相鄰模板之間應連接牢固、縫隙嚴密、平整順滑、無錯臺;預制構件上的預埋件均應有可靠固定措施。
The inspection well mold is mainly steel mold, the main material of the panel is Q235 steel plate, and the support structure can be section steel or steel plate. The specification can be selected according to the mold form, which shall meet the following requirements:
1. The mold shall have sufficient bearing capacity, stiffness and stability to ensure that it can reliably bear the weight, lateral pressure and working load of poured concrete during component production.
2. The mold shall be easy to assemble and remove, and shall be convenient for reinforcement installation, concrete pouring and curing.
3. The adjacent formworks shall be firmly connected, with tight gap, flat and smooth without staggered platform; Reliable fixing measures shall be taken for embedded parts on prefabricated components.
