Bridge bent cap adopting prefabricated limiting stop blocks and construction method
The invention relates to the technical field of capping beam construction, in particular to a bridge capping beam adopting prefabricated limiting stop dogs and a construction method.The bridge capping beam comprises a capping beam body fixedly arranged on an abutment and the limiting stop dogs, and the limiting stop dogs comprise the transverse limiting prefabricated stop dogs and the longitudinal limiting prefabricated stop dogs; stop block steel plates are embedded in the bottoms of the transverse limiting prefabricated stop blocks and the bottoms of the longitudinal limiting prefabricated stop blocks, a cover beam steel plate is embedded in the top of the cover beam body, and the stop block steel plates are welded to the cover beam steel plate, so that when the main beam is erected on the cover beam body, the transverse limiting prefabricated stop blocks abut against the two sides of the main beam, and the longitudinal limiting prefabricated stop blocks abut against the ends of the main beam. The transverse limiting prefabricated check blocks can be accurately connected to the two sides of the main beam in an abutting mode, the longitudinal limiting prefabricated check blocks can be accurately connected to the ends of the main beam in an abutting mode, and therefore the situation that the limiting check blocks need to be reduced is avoided as much as possible, and the fit clearance between the main beam and the limiting check blocks is eliminated as much as possible to ensure that the due limiting effect is achieved.
本申请涉及盖梁施工技术领域，尤其是涉及一种采用预制限位挡块的桥梁盖梁及施工方法，包括固设于墩台的盖梁本体以及限位挡块，限位挡块包括横向限位预制挡块以及纵向限位预制挡块，横向限位预制挡块底部、纵向限位预制挡块底部均预埋有挡块钢板，盖梁本体顶部预埋有盖梁钢板，且挡块钢板焊接于盖梁钢板，以令主梁架设于盖梁本体时，横向限位预制挡块抵接于主梁两侧、纵向限位预制挡块抵接于主梁端部。本申请能够使横向限位预制挡块准确抵接于主梁两侧，使纵向限位预制挡块准确抵接于主梁端部，从而尽量避免需要减小限位挡块的情况发生，以及尽量消除主梁与限位挡块之间的配合间隙确保起到应有的限位作用。
