Laminated slab type assembled box culvert
The invention discloses a laminated slab type assembled box culvert which comprises a cast-in-place concrete bottom plate, superimposed side wall components, a top plate prefabricated plate, post-poured inner side concrete, additional shear-resistant truss ribs, superimposed top plate inner reinforcing steel bars, double-sided superimposed inner and outer leaf reinforcing steel bars, top plate additional lap joint reinforcing steel bars, bottom plate reinforcing steel bars and bottom plate reserved additional joint bars. The advantages of prefabrication and cast-in-place are combined, the cast-in-place concrete bottom plate is cast-in-place, the transportation amount of the prefabricated parts is reduced, positioning and mounting of the prefabricated parts are facilitated, formwork manufacturing and supporting engineering is omitted through the superimposed side wall components and the top plate prefabricated plate, and the construction cost is reduced. The abutted seam of the cast-in-place concrete bottom plate and the superimposed side wall component is arranged at the plate thickness position above the axilla angle of the cast-in-place concrete bottom plate by one time, the most unfavorable stress position of the structure is avoided, the overall stress performance of the structure is improved, meanwhile, the additional shear-resistant truss ribs are additionally arranged at the ends of the top plate prefabricated plate, and adverse effects caused by canceling of the top axillary corners are effectively reduced.
本发明公开了一种叠合板式拼装箱涵，包括现浇混凝土底板、叠合式侧壁构件、顶板预制板、后浇内侧混凝土、附加抗剪桁架筋、叠合顶板内钢筋、双面叠合内外叶钢筋、顶板附加搭接钢筋、底板钢筋和底板预留附加插筋。本发明结合了预制和现浇的优点，现浇混凝土底板为现浇，减少了预制构件的运输量，且方便预制构件的定位和安装，叠合式侧壁构件和顶板预制板节省了模板制作和支撑的工程，降低了施工成本，且现浇混凝土底板和叠合式侧壁构件的拼缝设置在现浇混凝土底板腋角以上一倍的板厚位置处，避开了结构最不利受力位置，提高了结构的整体受力性能，同时，在顶板预制板端部加设附加抗剪桁架筋，有效降低了由于顶部腋角的取消造成的不利影响。
