Fiberboard bolt connection hollow slab beam and construction method thereof
The invention discloses a fiberboard bolt connection hollow slab beam and a construction method thereof, and belongs to the technical field of hollow slab beam construction.The hollow slab beam comprises at least two adjacent hollow slabs with rectangular sections, and a plurality of fiberboards which are oppositely symmetrical and flush with the side faces of the hollow slabs are sequentially and fixedly arranged on the two sides of the hollow slabs at intervals in the longitudinal direction; the upper end part and the lower end part of the fiber plate respectively extend and protrude out of the top end surface and the bottom end surface of the hollow plate, and an upper preformed hole and a lower preformed hole are respectively formed in the upper end part and the lower end part; the upper preformed holes and the lower preformed holes of the butt joint fiberboards on the adjacent hollow slabs are fixedly connected through bolts correspondingly, full-length transverse steel bars are arranged in the upper preformed holes of the multiple fiberboards in the same direction in the transverse direction in a penetrating mode, and concrete layers are poured on the top faces of the hollow slabs. The overall performance of the hollow slab beam can be enhanced, the quality defects that in the traditional hinge joint construction process, steel bars are not connected, and grouting is not compact are overcome, and later maintenance and load lifting and upgrading are facilitated.
本发明公开了一种纤维板螺栓连接空心板梁及其施工方法，属于空心板梁施工技术领域，空心板梁包括至少两个相邻的矩形截面空心板，空心板两侧沿纵向依次间隔固定设置多个相向对称且与空心板侧面相齐平的纤维板，纤维板的上端部和下端部分别伸展突出于空心板的顶底端面，上端部和下端部上分别开设有上预留孔和下预留孔；相邻空心板上相对接纤维板的上预留孔和下预留孔分别通过螺栓固定连接，且沿横向位于同一方向上多个纤维板的上预留孔中穿设布置有通长横向钢筋，以及在空心板顶面浇筑混凝土层。本发明能够增强空心板梁的整体性能，避免了传统铰缝施工过程中容易产生的钢筋不连接、灌浆不密实的质量缺陷，便于后期维修和提载升级。
