砖(石旋)的常规施工方法,是用木制拱架作为砖拱的胎模。无疑,这将造成木材的浪费,拆除后的木胎模再无周转价值,只能一次性摊销,从而加大工程成本。砖胎模具有节省木材、降低成本、施工方便、操作简单、保证工程质量等优点,且经过施工工地的实践,证明其效果良好。现将两种不同形式砖胎模发(石旋)介绍如下: The conventional construction method for brick (stone) is to use wooden arches as the mold for brick arches. Undoubtedly, this will result in the waste of wood. After the demolition of the wooden tire mold, there will be no turnover value, and it can only be amortized once, thereby increasing the cost of the project. Brick molds have the advantages of saving wood, lowering costs, convenient construction, simple operation, and ensuring project quality, etc., and they have proved to be effective after the practice of construction sites. Two different forms of brick and mortar tires (Shixuan) are introduced as follows:
