Prestress applying device for FRP (Fiber Reinforced Plastic) rib reinforcement of concrete beam and construction method of prestress applying device
According to the prestress applying device in concrete beam FRP rib reinforcement, at least two rows of tensioning anchoring devices are arranged on the left side of a mounting plate, 2-6 tensioning anchoring devices are arranged in each row, counter-force anchoring devices with the same row number as the tensioning anchoring devices are arranged on the right side of the mounting plate, and counter-force anchoring devices with the same number as the tensioning anchoring devices are arranged in each row. A positioning plate is arranged between the tensioning anchoring device and the counter-force anchoring device on the mounting plate; and a prestress applying machine is arranged on the positioning plate. The construction method using the device comprises the steps of processing the surface layer of the concrete beam bottom plate, longitudinally grooving the concrete beam bottom plate, installing the tensioning anchoring device and the counter-force anchoring device, anchoring the FRP rib and the counter-force fixing plate, installing the positioning plate, installing the prestress applying machine, applying prestress, removing the prestress applying device and pouring a reinforcing material. Compared with an existing concrete beam FRP rib reinforcing technology, large equipment and large anchorage devices do not need to be used, and an existing bridge can be subjected to prestress reinforcing.
一种混凝土梁FRP筋加固中预应力施加装置,在安装板上左侧至少设2排张拉锚固器，每排设2～6个张拉锚固器，安装板上右侧设与张拉锚固器排数相同的反力锚固器，每排设与张拉锚固器数字相同的反力锚固器，安装板上张拉锚固器与反力锚固器之间设定位板，定位板上设预应力施加机。使用该装置的施工方法由处理混凝土梁底板表层、混凝土梁底板纵向开槽、安装张拉锚固器和反力锚固器、锚固FRP筋和反力固定板、安装定位板、安装预应力施加机、施加预应力、拆除预应力施加装置并灌注加固材料步骤组成。与现有混凝土梁FRP筋加固技术相比，无需使用大型设备和大型锚具，可对现有桥梁进行预应力加固。
