Abstract

The invention relates to the technical field of processing and fastening of civil engineering, in particular to a glue injection device and method for a post-tensioning method. The glue injection device for the post-tensioning method comprises a pressure device, a plurality of glue injection pipes and glue discharge pipes, a U-shaped groove, a heating temperature control device and a pipe clamp, wherein a partition board is arranged in the U-shaped groove; an opening end of the U-shaped groove is fixedly connected with a concrete beam; CFRP (carbon fiber reinforced plastic) and the heating temperature control device are arranged in the U-shaped groove; a gap exists between the CFRP and the concrete beam; the pressure device is connected with two sides of the gap through the plurality of glue injection pipes and glue discharge pipes; the pipe clamp is used for clamping the glue discharge pipe after carbon fiber plate glue overflows the glue discharge pipe. According to the glue injection method, glue injection and glue layer curing are realized in the post-tensioning method by the aid of the glue injection device, and the technical problems of non-uniform distribution of carbon fiber plate glue, failure in control of glue layer thickness and failure in curing of glue layers at the proper temperature during CFRP prestress reinforcement are solved.

Description

technical field [0001] The invention relates to the technical field of civil engineering processing and fastening, in particular to a glue injection device and method for post-tensioning. Background technique [0002] Due to its high tensile strength, carbon fiber reinforced composite (CFRP) has been widely used in the reinforcement of concrete and other components. At present, the common way to use CFRP to strengthen components is to stretch CFRP to produce prestress. Pasting on the reinforced member, this method can enable CFRP to be pasted and anchored on the surface of the reinforced member with a set prestress, but the pasting method used is to directly apply carbon fiber sheet glue. The disadvantage of this method is that it is difficult to control the thickness of the carbon fiber sheet adhesive layer, and it is easy to cause the carbon fiber sheet adhesive to be unable to be cured at an appropriate temperature due to problems such as inability to solidify, long solid...
