Description
Technical field
The utility model is related to a kind of frame structure, more particularly to a kind of self-locking carbon cloth indirect strengthening concrete frame
Interior joint.
Background technology
Node is a very important position in concrete frame structure, and force-bearing situation is complicated more than beam column component,
Under geological process, the horizontal shear born is generally 4-6 times of column shearing, is fallen once destroying and would potentially result in total
It collapses destruction, it is therefore proposed that reliable and effective node seismic strengthening technology and corresponding design method have important engineering reality
Meaning.Existing reinforcing joint, which exists, does not form joint cores effective anchoring, and there are carbon fiber reinforced plastics
It is too early that material (CFRP) cloth hoop coheres glass, coheres glassbreak so as to generate, reduces the anti-seismic performance of node.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of self-locking carbon cloth indirect strengthening to mix
Solidifying soil Frames Joints, the technical solution of the self-locking carbon cloth indirect strengthening concrete frame interior joint are realized in
's：
A kind of self-locking carbon cloth indirect strengthening concrete frame interior joint, including frame column and frame beam plate, the frame
Plate of setting a roof beam in place is the T-shaped composite structure being made of Vierendeel girder and plate, and the frame column pastes one layer of column longitudinal direction L on along the longitudinal direction
Type CFRP bands, and the column longitudinal direction L-type CFRP bands are anchored using the CFRP cloth hoop of closing, on the frame beam plate
One layer of beam slab longitudinal direction L-type CFRP band is pasted in longitudinal direction, the beam slab longitudinal direction L-type CFRP bands pass through U-shaped cloth hoop self-locking
On parallel gate bar at beam slab inner corner trim, the parallel gate bar is fixed on by hollow movable joint screw rod under the edge of a wing of frame beam plate
Side, the hollow movable joint screw rod, which passes through the frame beam plate edge of a wing and passes through the nut of upper end, is fixed on frame beam plate top surface, the sky
Beam slab longitudinal direction L-type CFRP bands are fixed on frame beam plate top surface by section screw rod of being indecisive and changeable by being arranged on the lateral steel plate strip of back.
Further, the U-shaped cloth hoop is CFRP item hoops.
Further, structure glue is coated between longitudinal direction CFRP bands and frame column and the frame beam plate.
Further, the column longitudinal direction L-type CFRP bands of the frame column paste in ranging from column top/bottom latitude 350~
400mm ranges, the beam slab longitudinal direction L-type CFRP bands of the frame beam plate paste ranging from 600~700mm of beam-ends both sides.
Further, the parallel gate bar is formed by 2 round steel spot welding.
The reinforcing joint of the utility model, on Vierendeel girder direction using longitudinal L-type CFRP bands and CFRP cloth hoop into
The closing of styletable is anchored；To beam-ends, terminate U-shaped cloth hoop being self-locking in putting down at beam slab inner corner trim around self-locking is tied using CFRP cloth end
On row grid bar, then by wearing the wing hollow movable joint screw rod the lateral steel plate strip of parallel gate bar and top surface of the beam is fastenedly connected, forms envelope
The CFRP cloth hoops closed overcome the defects of U-shaped CFRP cloth hoop that beam-ends is just being put is difficult to pass through the plate edge of a wing, and to beam-ends L-type longitudinal direction
CFRP bands form reliable anchoring constraint, effectively prevent reinforcing the premature bonding stripping failure of fiber.
The reinforcing joint of the utility model can effectively improve the shear resistance of joint cores, and beam column end is avoided to reinforce
The failure of stripping in advance of fiber, while the ductility factor and energy dissipation capacity of joint cores can be improved, so as to further improve
The anti-seismic performance of joint cores.
