FRP rib quick connecting device and connecting method
The invention relates to a quick FRP rib connecting device and method, and relates to the technical field of FRP rib connection for concrete structures in civil engineering. Comprising a connecting sleeve, a heater and an extrusion die, the connecting sleeve is provided with a connecting cavity with two communicated ends, the connecting sleeve is a stainless steel connecting sleeve, and an annular thermoplastic layer is arranged on the inner wall. The FRP ribs are inserted into the connecting cavity from the two ends of the connecting sleeve respectively, the heater is used for heating the outer surface of the connecting sleeve to enable the thermal plastic layer to be heated and softened, then the extrusion die is used for extruding the outer surface of the connecting sleeve, and the thermal plastic layer is tightly attached to the FRP ribs. And then pressure is applied to the connecting sleeve, the plastic deformation of the connecting sleeve can generate pre-pressure on the internal thermal plastic layer and the FRP rib, and the connection reliability of the FRP rib is ensured. By means of the connection method, the connection efficiency of the FRP ribs is improved, and the problem that existing FRP rib connection needs long time is solved.
本申请涉及一种FRP筋快速连接装置及连接方法，涉及土木工程中用于混凝土结构的FRP筋连接技术领域。包括连接套筒、加热器和挤压模具，连接套筒具有两端连通的连接腔，连接套筒为不锈钢连接套筒，内壁设置有环形的热塑胶层。将FRP筋分别从连接套筒的两端插入到连接腔内，使用加热器对连接套筒外表面进行加热，使热塑胶层受热软化，然后使用挤压模具对连接套筒的外表面进行挤压，热塑胶层与FRP筋紧密贴合。之后结束对连接套筒施加压力，连接套筒的塑性变形会对内部的热塑胶层和FRP筋产生预压力，确保了FRP筋连接的可靠性。此种连接方法提高了FRP筋的连接效率，解决了现有的FRP筋连接所需时间较长的问题。
