A method for repairing and strengthening reinforced concrete buildings by sticking steel

Abstract

The present invention relates to a method for repairing and strengthening the bonded steel of a reinforced concrete building, which uses a device for repairing and reinforcing the bonded steel of a reinforced concrete building. The lower end of the platform is connected to the existing ground through a sliding fit, the upper end of the mobile platform is provided with a fixing mechanism, and the right side of the fixing mechanism is provided with a spraying mechanism. The present invention adopts the design concept of combining multiple control structures to repair reinforced concrete buildings with steel Reinforcement, the overall size of the structure that acts as a clamping steel plate can be adaptively adjusted according to the size of the steel plate to be clamped, and then achieve the purpose of corresponding clamping, and expand the range of processing objects that the device is applicable to.

Description

technical field [0001] The invention relates to the technical field of reinforced concrete, in particular to a method for repairing and reinforcing reinforced concrete buildings by sticking to steel. Background technique [0002] Bonded steel is suitable for general bending and tension members that are subjected to static forces. Bonded steel reinforcement is also known as bonded steel plate reinforcement. The concrete forms a unified whole, and the good tensile strength of the steel plate is used to achieve the purpose of enhancing the bearing capacity and stiffness of the components. The main materials for bonding steel reinforcement are building structural glue and steel plates, and the auxiliary materials are (expansion) bolts, etc., and the technological process is steel plates. Production → base treatment → unloading → glue dispensing → pasting → fixing and pressurizing → curing → inspection → anti-corrosion treatment, but the following problems will occur during the r...

AI Technical Summary

Problems solved by technology

[0003] 1. The overall control function of the steel plate clamping structure is relatively simple. The range of different sizes of steel plates that can be clamped is relatively narrow, and at the same time, the device as a whole is more suitable for the bonding of steel on vertical concrete walls, while facing the ceiling or On inclined surfaces, the workability of the device is lower;

[0004] 2. Hard impurities such as detachable particles on the concrete wall can easily cause a decrease in the adhesion between the steel plate and the wall, and when cleaning impurities on the surface of the suspended ceiling, the removed impurities will easily fall to the surface of the steel plate, and at the same time In the case of no external pressing or the pressing surface is small, the bonding effect between the steel plate and the wall is not satisfactory
