[0002] At present, affected by natural disasters such as fire and earthquake, reinforced concrete structures are prone to varying degrees of damage. If the damaged reinforced concrete structures are to be replaced, a large amount of material and financial resources will be consumed. Therefore, it is of great significance to study how to repair and reinforce the damaged or insufficiently bearing reinforced concrete structures so that the reinforced concrete structures after repair and reinforcement can still be used normally. The existing reinforcement methods for concrete beams mainly include: increasing the cross-section method, external fiber cloth method, external steel plate method, external angle steel method, external steel mesh fine stone concrete method, external prestressing method, etc. However, the above traditional reinforcement methods generally have the following problems: 1. For those with For concrete beams with surface damage, it is usually necessary to first repair the remaining beam section after the severely damaged concrete on the surface has been chiseled out with grouting material or fine stone concrete, and then reinforce it by wrapping it with fiber cloth, angle steel, steel mesh fine stone concrete or applying external prestressing. There is a hidden danger that the surface repair material is easy to fall off under the combined action of long-term load and external environment, which greatly affects the long-term reinforcement effect. 2. Brittle peeling failure is prone to occur between the external reinforcement material and the surface of the repaired concrete beam. 3. There are differences in width of concrete beams at different positions, and the reinforcement device cannot be adjusted according to the width of the concrete beam. Therefore, a building reinforcement device is proposed to solve the above problems. Utility Model Content
