[0024] 1 The method of sticking steel plates with initial tension to strengthen the concrete structure adopts the following process:
[0025] ①. Design reinforcement parameters based on the original design data of the reinforced concrete structure, as well as the inspection and evaluation of the structure.
[0026] ②. Surface treatment of the reinforcement structure and the bonding surface of the steel plate, mainly sanding and cleaning.
[0027] ③. Drill high-strength bolt holes at the corresponding positions of the structure to be reinforced and the steel plate (the position of the bolt holes on the steel plate should consider the elongation of the tensile steel plate).
[0028] ④. Install the steel plate on a special tension frame that can be used repeatedly, and tension it to control the stress.
[0029] ⑤. Use a spatula to apply structural glue on the processed concrete surface and steel plate at the same time.
[0030] ⑥. Use fasteners to make the steel plate and the concret...
