Construction method for reinforcing reinforced concrete beam through prestress FRP sheet
The invention relates to a construction method for reinforcing a reinforced concrete beam through a prestress FRP sheet, and belongs to the technical field of structural engineering and bridge engineering construction. On a manufacturing platform, FRP fiber cloth is expanded and has certain tension through a weight, the middles of the multiple layers of FRP fiber cloth are bonded together, and therefore the FRP sheet is prepared; and then the FRP sheet is tensioned through a tensioning device, and the FRP sheet is anchored to the portion, needing to be reinforced, of the reinforced concrete beam through an anchoring component. The device structure is simple, assembling and manufacturing are convenient, use is convenient, the FRP sheet can be tensioned through a wrench, and indoor and outdoor construction is facilitated. Meanwhile, the method is simple in construction and low in cost and can be used for bridges and civil buildings, and the ends of pasted FRP plates are not prone to debonding.
本发明涉及一种预应力FRP片材加固钢筋混凝土梁的施工方法，属于结构工程和桥梁工程施工技术领域。在制作平台上，展开FRP纤维布并利用重物使其有一定的张力，多层FRP纤维布的中部粘贴在一起，从而实现FRP片材的制备，随后利用张拉装置完成对FRP片材的张拉，用锚固部件将FRP片材锚固在钢筋混凝土梁需要加固的部位。本装置结构简单，便于组装制造，使用方便，通过扳手即可实现对FRP片材的张拉，便于在室内外施工。同时该方法施工简单、成本低廉，可用于桥梁和民用建筑，粘贴后的FRP板端部不易脱粘。
