硫磺砂浆后张法施工是预应力施工一项新工艺,它综合了先张和后张的优点,不需预留孔道,不用台座,特别适用于双向曲线配筋的连续板、连续梁。在批林批孔运动的推动下,在上级党委的领导下,我们以某仓库二层楼房为试验楼,对硫磺砂浆预应力升板结构进行了试验研究,现就硫磺砂浆预应力结构的耐火问题 Sulfur mortar post-tensioned construction is a new process of prestressed construction. It combines the advantages of pre-tensioning and post-tensioning. There is no need to reserve a tunnel, not a pedestal, and it is particularly suitable for continuous plates and continuous beams with bi-directional curve reinforcement. Under the impetus of the approval of the approved batch campaign, under the leadership of the superior party committee, we took a two-story warehouse in a warehouse as a pilot building to conduct a pilot study on the prestressed riser structure of the sulphur mortar, and now the fire resistance of the prestressed structure of the sulphur mortar was achieved. problem
