Bridge self-stress hollow slab structure and construction method thereof
The self-stress hollow slab structure of the bridge comprises a hollow slab and a self-stress rigid connection beam, the hollow slab is composed of a self-stress bottom plate, two thin rib plates and a top plate, and the self-stress rigid connection beam is poured above the extending parts of the two adjacent bottom plates; the self-stress rigid connection beam is composed of micro-expansion concrete, a rigid connection beam longitudinal rib, a rigid connection beam stirrup, a left single-limb rib, a right single-limb rib, two adjacent lower inclined steel bar extending parts and two adjacent upper inclined steel bar extending parts. The construction method comprises the following steps: a) welding the expansion plates and the longitudinal self-stress ribs; b) pouring high-expansion concrete; c) supporting an inner template of the hollow slab; d) pouring common concrete; e) binding a steel reinforcement framework of the self-stress rigid connection beam; and (f) micro-expansive concrete is poured. According to the bridge self-stress hollow slab structure and the construction method thereof, rigid connection between the hollow slab and the self-stress rigid connection beam is achieved, the situation that a single hollow slab is stressed is avoided, and the service life of the hollow slab is prolonged.
本发明的桥梁自应力空心板结构，包括空心板和自应力刚接梁，空心板由自应力底板、两薄肋板和顶板构成，自应力刚接梁浇筑于两相邻底板外伸部的上方；自应力刚接梁由微膨胀混凝土、刚接梁纵向筋、刚接梁箍筋、左单肢筋、右单肢筋、两相邻下斜钢筋外伸部和两相邻上斜钢筋外伸部构成。本发明的施工方法包括：a).焊接膨胀板和纵向自应力筋；b).浇筑高膨胀混凝土；c).支空心板内模板；d).浇筑普通混凝土；e).绑扎自应力刚接梁的钢筋骨架；f).浇筑微膨胀混凝土。本发明的桥梁自应力空心板结构及其施工方法，实现了空心板与自应力刚接梁的刚性连接，不会出现单个空心板受力的情形，延长了空心板的使用寿命。
