渡口师范学校教学楼的教室部分长9.9m,宽6.4m,纵墙承重。楼板原设计为厚19cm,长6.4m的预应力空心板(按川G203图集制作)。由于板内高强钢丝及其压波处理工艺不能解决,此板一时不能生产,直接影响了工程进展。后来在四川省建科所的大力支持下,另行设计了预应力迭合简支板,解决了材料和技术上的难题。
The classroom part of the teaching building of Dukou Normal School is 9.9m long and 6.4m wide, and the vertical wall bears weight. The floor slab was originally designed as a prestressed hollow slab with a thickness of 19cm and a length of 6.4m (made by Sichuan G203 Atlas). Because the high-strength steel wire in the plate and its pressure wave treatment process cannot be solved, this plate cannot be produced for a time, which directly affects the progress of the project. Later, under the strong support of the Sichuan Provincial Institute of Engineering Sciences, the pre-stressed superimposed simple support plate was separately designed to solve the material and technical problems.
