Construction method of large-span retard-bonded prestressed floor cover plate
The invention relates to a construction method of a large-span retard-bonded prestressed floor cover plate, and belongs to the field of construction methods of floor cover plates. The construction method comprises the following steps of S1, erecting a plate bottom framework; S2, mounting a steel reinforcement framework; S3, arranging prestressed tendons; S4, fixing the prestressed tendons; S5, placing hollow blocks; S6, reinforcing the hollow blocks; S7, concrete pouring and curing; S8, prestress tensioning; and S9, cutting and plugging the prestressed tendons. According to the prestressed tendon fixing step in the step S4 and the hollow block reinforcing step in the step S6, the effect that the hollow blocks are not prone to floating in the construction process can be achieved.
本申请涉及一种大跨度缓粘结预应力楼盖板施工方法，属于楼盖板施工方法领域，其包括以下步骤：S1、支设板底模板；S2、安装钢筋骨架；S3、预应力筋布设；S4、预应力筋固定；S5、空心块的放置；S6、空心块的加固；S7、混凝土浇筑与养护；S8、预应力张拉；S9、预应力筋切割和封堵。本申请中S4中的预应力筋固定步骤和S6中空心块的加固步骤，可达到使空心块在施工过程中不易上浮的效果。
