Technical Field
The utility model relates to a carbon fiber reinforced plate column node earthquake-resistant structure belongs to the carbon fiber reinforcement technology field of construction.
Background
The plate column system has attracted more and more attention due to the advantages of good integrity, large building space, good economic benefit and the like. However, because the support of the beams is lacked under the floor slab of the system, only the plate columns are connected at the column joints, and the anti-cutting problem of the plate column joints, particularly the plate column joints, becomes a weak link of the whole system. In order to overcome the defect of displacement of the node of the plate column, the common method is to reinforce the node by sticking steel or enlarging the section of concrete. And the utility model discloses then provide a reinforcement mode to the board post node through the carbon fiber.

The plate-reinforced carbon fiber layer and the column-reinforced carbon fiber layer are carbon fiber plates or carbon fiber cloth.
The plate reinforced carbon fiber layer is fixed on the plate structure in a pasting mode.
The steel plates on the same side of the plate structure are a plurality of strip-shaped steel plates which are arranged in parallel at intervals.
The plate-reinforced carbon fiber layer and the column-reinforced carbon fiber layer include a plurality of strip-shaped carbon fiber reinforcing strips.
The crab-bolt is a plurality of, every the crab-bolt passes behind the steel sheet and passes the carbon fiber reinforcement area that sets up on the plate structure.
Adopt above-mentioned technical scheme, the utility model discloses a carbon fiber reinforced plate column node earthquake-resistant structure compares with the reinforcement mode through gluing steel or increase concrete cross-section among the prior art, has following beneficial effect:
1. the carbon fiber high-strength high-modulus can effectively improve the node rigidity;
2. the carbon fiber is soft and easy to construct, and can be effectively attached to adapt to the change and intersection of the original section shape;
3. drilling is only needed at the position where the anchor bolt is arranged, and the rest parts can adopt a carbon fiber pasting construction mode, so that the construction period is short;
4. the carbon fiber material is light and convenient, the size of the original component is not increased, and the applicable application of the original structure is not influenced.
