steel plate beam widening hollow plate beam structure
The invention discloses a steel plate beam widening hollow plate beam structure and relates to the field of bridge engineering. The steel plate beam widening hollow plate beam structure comprises a hollow plate beam, a widening steel plate beam and a corrugated steel plate, the two ends of the corrugated steel plate are connected with the hollow plate beam and the widening steel plate beam through connecting plates correspondingly, and a polyvinyl alcohol fiber reinforced cement-based material composite layer connected with the hollow plate beam and the widening steel plate beam is laid on the top of the corrugated steel plate. Bridge floor cast-in-place layers connected with the two ends of the polyvinyl alcohol fiber reinforced cement-based material composite layer are laid on the hollow slab beams and the widened steel plate beams respectively, and bridge floor asphalt pavement layers are laid on the bridge floor cast-in-place layers and the polyvinyl alcohol fiber reinforced cement-based material composite layer. The steel plate beam widening hollow plate beam structure provided by the invention can solve the problem of poor settlement caused by heavy self weight and concrete shrinkage and creep at the joint of the widening structure of an old hollow plate bridge, and has the advantages of low construction difficulty, reduction of the use amount of reinforcing steel bars and increase of economic benefits.
一种钢板梁拼宽空心板梁结构，涉及桥梁工程领域。该钢板梁拼宽空心板梁结构包括空心板梁、拼宽钢板梁及两端分别通过连接板与空心板梁和拼宽钢板梁连接的波形钢板，波形钢板的顶部铺设有分别与空心板梁和拼宽钢板梁连接的聚乙烯醇纤维增强水泥基材料复合层，空心板梁和拼宽钢板梁上分别铺设有与聚乙烯醇纤维增强水泥基材料复合层两端连接的桥面现浇层，桥面现浇层和聚乙烯醇纤维增强水泥基材料复合层上铺设有桥面沥青铺装层。本申请提供的钢板梁拼宽空心板梁结构能解决旧空心板桥的拼宽结构接缝处因自重较重、混凝土收缩徐变引起的沉降差，同时具有施工难度低、减少钢筋使用量增加经济效益的优点。
