Abstract
The utility model discloses a kind of novel reinforced concrete frame beam column reinforcing joints, including Vierendeel girder and frame column, Vierendeel girder is provided with perforation at a certain distance from frame column, perforation passes through for prestress rope, prestress rope blocks fixation at the Vierendeel girder for applying prestressing force side with wire line hitch, and the prestress rope is sealed anchoring across after perforating by pouring hot melt adhesive；The utility model using it is pliable, intensity is high, corrosion resistant prestress rope carry out joint reinforcing, the shear-carrying capacity of joint cores can be effectively improved, joint cores are formed with effective hoop constraint, so that destruction of a node position is shifted to beam-ends, form the structure node of strong column and weak beam and the weak component of strong node, the energy dissipation capacity and ductility of node can be effectively increased simultaneously, effectively it can inhibit and delay the development in joint cores crack using prestress rope, there is preferable promotion prospect.
Description
Technical field
The utility model is related to a kind of reinforcing joint, more particularly to a kind of novel reinforced concrete frame beam column reinforces section
Point.
Background technology
Frame structure has a large capacity and a wide range in China, a large amount of existing frame structure generally existing beam column node core area shearing resistance carryings
The defects of scarce capacity, seriously affects the security performance of structure, and there is an urgent need for carry out reinforcement and strengthening.Existing reinforcement means such as pastes fibre
Method for strengthening, reinforcement by sticking of sheets and Enlargement of Section etc. are tieed up, these reinforcement means cannot form reinforcing joint effective circumferential direction
Constraint, while also there are the phenomenon that Stress resort.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of novel reinforced concrete frame beam column
Reinforcing joint, what the technical solution of the novel reinforced concrete frame beam column reinforcing joint was realized in：
A kind of novel reinforced concrete frame beam column reinforcing joint, including Vierendeel girder and frame column, Vierendeel girder includes four,
The four sides with the frame column is fixedly connected respectively, and the Vierendeel girder is provided with perforation at a certain distance from frame column, described
Perforation passes through for prestress rope, and the prestress rope uses wire line hitch at the Vierendeel girder for applying prestressing force side
Fixation is blocked, the prestressing force of the prestress rope is the punching jack by applying the Vierendeel girder both sides of prestressing force side
Apply with reinforcing pedestal and wire cable clamp, the prestress rope is close by pouring hot melt adhesive progress across after perforating
Sealing off and covering anchorage is consolidated.
Further, the quadrangle intersection of the prestress rope and frame column carries out chamfered.
Further, the radius of the chamfered is 25~30mm, and pastes chamfering iron plate.
Further, the aperture of the perforation at least ensures that a prestress rope passes through, the application prestressing force one
The perforation of side at least ensures that two prestress ropes pass through.
Further, the prestress rope at least two are distributed in the intersection of Vierendeel girder and frame column up and down.
Further, distance of the perforation apart from frame column is 10~15mm.
The utility model using it is pliable, intensity is high, corrosion resistant prestress rope carry out joint reinforcing, can be effective
The shear-carrying capacity of joint cores is improved, joint cores are formed with effective hoop constraint so that destruction of a node position is to beam
End transfer, forms the structure node of strong column and weak beam and the weak component of strong node, at the same can effectively increase node energy dissipation capacity and
Ductility effectively can be inhibited and delayed the development in joint cores crack using prestress rope, before having preferable promote
Scape.

Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Fig. 1~2, a kind of novel reinforced concrete frame beam column reinforcing joint, including Vierendeel girder 1 and frame column 2,
Vierendeel girder 2 includes four, and the four sides with the frame column 1 is fixedly connected respectively, and the Vierendeel girder 2 is apart from 1 one spacing of frame column
Place is provided with perforation 3, the perforation 3 passes through for prestress rope 4, and the prestress rope 4 is applying prestressing force
Fixation is blocked with wire line hitch 10 at the Vierendeel girder 2a of side, the prestressing force of the prestress rope 4 in advance should by applying
What the punching jack 6 and reinforcing pedestal 7 and wire cable clamp 8 of the Vierendeel girder 2a both sides of power side applied, the prestressing force
Steel wire rope 4 by pouring hot melt adhesive 9 is sealed anchoring after passing through perforation 3.
When it is implemented, the quadrangle intersection of the prestress rope 4 and frame column 1 carries out chamfered 5.
Preferably, the radius of the chamfered 5 is 25~30mm, and pastes chamfering iron plate.
When it is implemented, the aperture of the perforation 3 at least ensures that a prestress rope 4 passes through, the application in advance should
The perforation 3a of power side at least ensures that two prestress ropes 4 pass through.
When it is implemented, the prestress rope 4 at least two, is distributed in the friendship of Vierendeel girder 2 and frame column 1 up and down
At boundary.
When it is implemented, 3 distance apart from frame column 1 of the perforation is 10~15mm.
The technology contents and technical characteristic of the utility model have revealed that as above those skilled in the art still may base
The replacement and modification without departing substantially from the utility model in essence are made in the teaching of the utility model, therefore, the utility model protection
Range is not limited to the revealed content of embodiment, also including various replacements and modification without departing substantially from the utility model in essence.
