Prestressed concrete laminated slab wedge-shaped abutted seam grouting structure and construction method
According to the prestressed concrete laminated slab wedge-shaped abutted seam grouting structure and the construction method, pull rod holes are reserved in the direction of a prestressed concrete laminated slab wedge-shaped abutted seam every 2 meters, grouting holes are reserved in the direction of the prestressed concrete laminated slab wedge-shaped abutted seam every 10 meters, formwork pull rods penetrate through the pull rod holes to fix a bottom sealing formwork on the lower portion of a prestressed concrete laminated slab, and under the action of pressure, the grouting holes are formed in the bottom sealing formwork; crack pouring cement mortar is poured into the wedge-shaped abutted seams through the reserved grouting holes, after the crack pouring cement mortar reaches the strength, the excessive formwork pull rods on the upper portion and the lower portion of the floor slab are cut off, the bottom sealing formwork is dismantled, alkali-resisting gridding cloth is scraped on the wedge-shaped abutted seams in batches, then surface layer cement mortar is brushed, and the abutted seam pouring construction can be completed. According to the method, the grouting hole, the pull rod hole and the formwork pull rod are used in cooperation, the crack pouring cement mortar is injected into the wedge-shaped abutted seam through the reserved grouting hole under the action of pressure till the wedge-shaped abutted seam is filled, the wedge-shaped abutted seam of the floor slab can be filled with the crack pouring cement mortar more easily, and the construction quality is greatly improved.
本发明公开一种预应力混凝土叠合板楔形拼缝灌浆结构及施工方法，沿着预应力混凝土叠合板楔形拼缝的方向每2米留设有拉杆孔洞，每10米留设有灌浆孔洞，模板拉杆贯穿拉杆孔洞固定预应力混凝土叠合板下部封底模板，在压力作用下，灌缝水泥砂浆通过留设的灌浆孔洞注入到楔形拼缝中，待灌缝水泥砂浆达到强度后，截断楼板上下多出的模板拉杆，拆除封底模板，对楔形拼缝批刮耐碱网格布，再涂刷面层水泥砂浆即可完成拼缝灌缝施工。本发明充分利用了灌浆孔洞、拉杆孔洞、模板拉杆的配合使用，将灌缝水泥砂浆通过留设的灌浆孔洞在压力作用下注入到楔形拼缝中直至注满，能够让灌缝水泥砂浆更容易将楼板的楔形拼缝灌满，大大提高了施工质量。
