我们经过施工现场的调查研究,于1990年,在预制楼板灌缝施工中采用工具式灌缝模板(简称托铁灌缝器)。通过三年多应用,它比传统的预制楼板灌缝工艺效果好,实用性强。 1.主要特点 ①构造简单、制作容易、形体轻巧,可反复使用、不易损坏;②可适用于民用和工业建筑的楼面、屋面的预制板灌缝,包括120mm、180mm高的多孔 After investigation and study at the construction site, in 1990, we used the tool-type grouting template (abbreviated as yoke) in the construction of prefabricated floor grouting. After more than three years of application, it is more effective and practical than the conventional prefabricated floor sealing process. 1. Main features 1. Simple structure, easy to make, light body, can be used repeatedly, not easy to damage; 2 can be applied to the prefabricated panels of residential and industrial building floor, roof, including 120mm, 180mm high porous
