The invention relates to a bridge deck seamless connecting plate of web wave-shaped FRP plates filled with concrete, which comprises FRP wave-shaped webs, an FRP bottom plate, filled concrete, in-hole FRP ribs and tensile FRP ribs, and the FRP wave-shaped webs are arranged in multiple rows in the longitudinal direction of a bridge and span beam bodies or bridge abutments on the left side and the right side; the FRP bottom plate is placed on the bottom face of the connecting plate, and the two ends of the FRP bottom plate are placed on the beam bodies or the bridge abutments on the left side and the right side respectively to support the FRP corrugated web. The FRP corrugated web and the FRP bottom plate are glued into a whole; filling concrete is poured between the FRP corrugated web and the FRP bottom plate; holes are formed in the FRP corrugated web, and FRP ribs are arranged in the holes in a penetrating mode; thin-layer PVC (polyvinyl chloride) materials are laid on contact surfaces between the FRP bottom plate and the beam bodies or the bridge abutments on the left side and the right side; and reinforcing steel bars extending out of the beam bodies on the two sides or the bridge deck slabs of the bridge abutments are embedded in the filled concrete.

本发明涉及内填混凝土的腹板波折形FRP板的桥面无缝连接板，包括：FRP波折形腹板，FRP底板，内填的混凝土，孔中FRP筋，受拉FRP筋，FRP波折形腹板沿桥梁纵向多排布置，跨越左、右两侧梁体或桥台；FRP底板放置于连接板底面，其两端分别放置于左、右两侧梁体或桥台上，支撑FRP波折形腹板；FRP波折形腹板与FRP底板通过胶接形成整体；在FRP波折形腹板和FRP底板之间浇筑内填混凝土；在FRP波折形腹板上开孔，内穿孔中FRP筋；FRP底板与左、右两侧梁体或桥台之间的接触面铺设薄层PVC材料；两侧梁体或桥台桥面板伸出的钢筋埋置于内填混凝土中。
