一、概述近年来,我县在不断实践的基础上,制造了迭合式预应力空心板。这是由预应力板梁与普通混凝土预制拱波和二次加浇的混凝土组成。预应力梁板主要放在受拉区内,拱波和现浇部分放在受压区内。这样,迭合式预应力空心板与预应力空心板在受力上和施工上都有些不同,经过比较分析证明,迭合式预应力空心板有如下的优点:(1)预应力板梁和拱波分别预制,可以标准化、工厂化生产,并减少空心板的拔
First, an overview In recent years, my county in constant practice, based on the manufacture of laminated prestressed hollow slab. This is composed of prestressed girder and ordinary concrete prefabricated arch wave and secondary pouring concrete. Prestressed beams mainly in the tension zone, arch waves and cast-in-place on the pressure zone. In this way, the prestressed laminated prestressed hollow slab and the prestressed hollow slab in the force and construction are somewhat different, after a comparative analysis shows that laminated prestressed hollow slab has the following advantages: (1) Prestressed girder and arch wave Separate prefabricated, can be standardized, factory production, and reduce the hollow plate pull
