Embodiment Construction

[0028] The present invention is a method for strengthening and repairing non-load-bearing concrete members. In order to achieve the above object, the present invention proposes a method for strengthening and repairing non-load-bearing concrete members, which includes the following process steps in sequence:

[0029] a) Set-out positioning: connect the fractured part of the concrete to the original state, position, set-out, and mark the position, size, and depth of the drill hole;

[0030] b) Fracture surface treatment: use an angle grinder to polish the concrete fracture surface, and use a blower to blow off the floating dust on the concrete fracture surface;

[0031] c) Drilling: Drilling with an electric hammer. If the concrete strength grade is not lower than C20, grade II (grade III) threaded steel bars, Q235, Q345 grade bolts and 5.6 grade screw rods, the depth of the drilled hole is 15d, and the anchorage force of a single pullout test is greater than the yield value of ...

Abstract

The invention discloses a non-bearing concrete component reinforcement repair method. The method comprises the process steps in sequence of: paying-off positioning, fracture indication treatment, drilling, drilling cleaning, reinforcement derusting, steel bar embedding glue preparation, chemical steel bar embedment, primary curing, surface leveling, adhesive stirring, primer brushing, carbon fiber cloth reinforcement, secondary curing, appearance surface finishing, and detection. The chemical steel bar embedment and carbon fiber reinforcement technologies are applied to reinforce the fracture diseases of non-bearing concrete components to solve one technical difficulty perplexed for a long time in the architectural cultural heritage protection. The advanced technology is applied to prevent wrong actions of disassembly and abandon of disease components and loss of history information, so that fractured components can be reused, the history information is preferably retained, the destruction of a traditional reinforcement method to the building style can be solved, and more purposes are achieved.

Description

【Technical field】 [0001] The invention relates to the restoration and protection of architectural cultural heritage, especially the application of new materials and new techniques to the restoration and protection of architectural cultural heritage. 【Background technique】 [0002] In the modern architectural cultural heritage, there are a large number of non-load-bearing concrete components, most of which are decorative components, which often contain the memory of a specific era and a specific cultural and historical environment, and are an important "key" for the study of cultural heritage. [0003] Affected by natural or human factors, the fracture of concrete components is a common building disease. The value of cultural heritage is that it contains specific historical information, and the core mission of its restoration is to preserve the original physical remains as much as possible and display them properly. This requires that the restoration of building components s...
