检查井模具以钢模为主,面板主材选用Q235钢板,支撑结构可选型钢或者钢板,规格可根据模具形式选择,应满足以下要求:
1.模具应具有足够的承载力、刚度和稳定性,保证在构件生产时能可靠承受浇筑混凝土的重量、侧压力及工作荷载。
2.模具应组装、拆模方便,且应便于钢筋安装和混凝土浇筑、养护。
3.相邻模板之间应连接牢固、缝隙严密、平整顺滑、无错台;预制构件上的预埋件均应有可靠固定措施。
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.
