Grouting template structure for hinge joint of prestressed concrete hollow slab girder
The invention relates to a prestressed concrete hollow slab girder hinge joint grouting formwork structure which comprises a hanging formwork (2) matched with a slab girder hinge joint (1a), the hanging formwork (2) is connected with a slab girder (1) through a hanging bolt (3), the hanging formwork (2) is provided with a pair of parallel pasting adhesive tapes (4), the pasting adhesive tapes (4) are symmetrically arranged on the two sides of the hanging formwork (2) in the length direction, and a piece of formwork cloth (5) is arranged between the two pasting adhesive tapes (4). The pasting adhesive tape (4) is made of rubber materials, the thickness of the pasting adhesive tape (4) is larger than that of the formwork cloth (5), the lower end of the hanging bolt (3) is connected with the clamping pin (6), and the upper end of the hanging bolt (3) is connected with the tensioning and fixing device (7). The method has the advantages that the filling compactness of the bridge plate bottom hinge joint grouting material is improved, slab staggering of the beam plate bottom hinge joint is reduced, the appearance quality problem of the bridge plate bottom hinge joint and the bottom of a plate beam is fundamentally solved, and the long-term durability of the plate beam hinge joint is improved.
本发明涉及一种预应力混凝土空心板梁铰缝灌浆模板结构，包括与板梁铰缝（1a）相配合的吊模（2），吊模（2）通过吊栓（3）与板梁（1）相连，吊模（2）上设有一对相互平行的粘贴胶条（4），粘贴胶条（4）沿着吊模（2）长度方向两侧对称设置，两个粘贴胶条（4）之间设有一个模板布（5），粘贴胶条（4）由橡胶材料制成且其厚度大于模板布（5）的厚度，吊栓（3）的下端与卡销（6）相连，吊栓（3）的上端与拉紧固定装置（7）相连。本发明的优点是提高桥梁板底铰缝灌浆材料填充密实度，减少梁板底铰缝错台，从根本上避免桥梁板底铰缝及板梁底部外观质量问题，提高板梁铰缝长期耐久性。
