FRP sheet connecting structure of prefabricated concrete beam and slab system and method
The invention provides an FRP sheet connecting structure of a prefabricated concrete beam and slab system and a method. Peripheral side surfaces of full-thickness prefabricated slabs are adjacent to side surfaces of floor beams; an about 20 mm wide adjusting seam is formed between each prefabricated slab and each floor beam and between the prefabricated slabs and is filled with high-strength micro-expansion mortar; planar FRP sheets for anti-bending connection are attached to the top surfaces of joints of the prefabricated slabs and the floor beams and the top surfaces and the bottom surfacesof joints of the prefabricated slabs; folding surface type FRP sheets for anti-shear connection are also attached to the joints of the prefabricated slabs and the floor beams and the joints of the prefabricated slabs; and the fiber direction of the FRP sheets is perpendicular to the longitudinal direction of the joints. The problems that side forms of prefabricated parts are complicated due to thefact that ribs extend out of the periphery of existing platy prefabricated parts, the production efficiency is low, transportation and hoisting operation are difficult and the like are solved; and the problem that substantial wet operation on the scene due to stacking pouring of existing prefabricated slabs and the problem of too large thickness of the slabs are solved.
本发明提供的一种预制混凝土梁板体系的FRP片材连接结构及方法，全厚度预制板的四周侧面与楼面梁侧面相邻；预制板与楼面梁之间以及预制板与预制板之间均设有一条约20mm宽的调节缝，调节缝内填有高强微膨胀砂浆；在预制板与楼面梁的接缝顶面以及预制板与预制板的接缝顶面和底面，均粘贴有抗弯连接用平面状FRP片材；在预制板与楼面梁以及预制板与预制板的接缝处，还粘贴有抗剪连接用的折面状FRP片材；FRP片材的纤维方向垂直于接缝纵向。本发明解决了现有板类预制构件四周出筋带来的预制构件边模复杂、生产效率低下、运输吊装操作困难等问题；解决了现有预制板叠合浇筑带来的现场大量湿作业问题以及楼板厚度过大问题。
