Description
Technical Field
The utility model relates to a building engineering technical field, concretely relates to novel reinforced concrete column reinforced structure.
Background
At present, in civil engineering construction, a plurality of new reinforcing technologies exist, and the reinforcing technology of the structural main body in the prior art is mature. In design application, a plurality of engineering examples of reinforcement designs of concrete structures already exist, wherein the reinforcement design of the reinforced concrete frame column is the most extensive, and the reinforced concrete can bear considerable weight, so that the safety of the building can be ensured to a great extent in meeting the use requirement of the building. However, the stress conditions of the steel bars and the concrete are different greatly, and if the proportion of the steel bars and the concrete is in a problem in the design process, or the steel bars and the concrete are not maintained properly during use, and the building quality is seriously affected due to natural disasters such as earthquake and the like, the structural safety of the house is damaged, or the house needs to be changed in use or added with a layer due to new use requirements, and the original structure needs to be reinforced. The reinforced concrete structure reinforcing scheme needs to be analyzed according to the actual conditions of a house, and the scheme of improving the bearing capacity of horizontal and vertical members, changing a structural system and the like can be adopted. When the reinforcing scheme is determined, the economic effects of building use and structure construction are integrated, the original structure is not damaged too much, the original structural members are kept as much as possible, and the unnecessary structural members are prevented from being disassembled, cut and replaced.
The concrete reinforcing method mainly comprises the following steps: 1. the method for reinforcing the section is widely used for reinforcing the components such as reinforced concrete beams, plates, columns and the like, and 2, the method for reinforcing the concrete structure by wrapping section steel around the concrete component is used for reinforcing the concrete structure without increasing the size of the concrete component and greatly improving the bearing capacity. The corrosion resistance can be improved by adopting reliable protection measures; 3. the method for reinforcing the bonded carbon fiber is characterized in that the carbon fiber is bonded outside the concrete member through a bonding agent or other fixing modes, so that the carbon fiber and the concrete are stressed cooperatively and deformed together, and the bearing capacity is improved; 4. other reinforcement methods that alter the stress path of the structure.
When the frame column is reinforced by the method for reinforcing the section by adding, chiseling old concrete and planting steel bars newly added or connecting the old concrete and the steel bars with the original steel bars are key points of the reinforcement design of the method for reinforcing the section by adding the concrete. Currently, many reinforcement designs do not completely address the two important points above. When the number of the frame column layers needing to be reinforced is large, effective connection of newly-added frame column longitudinal bars is difficult to guarantee under the condition that a structural floor slab exists. Meanwhile, the newly added frame column stirrup is difficult to be connected with the original frame column stirrup in a sealing manner, so that the frame column with the reinforced cross section cannot play the functions of bearing pressure, shearing resistance and bending resistance most effectively. In short, all new and old members (walls, columns) are connected only by bonding of concrete itself, and no hoop reinforcement is formed, so that no integral bearing member is formed.
