Description
Technical field
The invention belongs to reinforced concrete technology fields, and in particular to a kind of shaped steel is novel through cast-type concrete frame
Beam-to-column joint structure.
Background technology
Both at home and abroad repeatedly shake greatly it was verified that reinforced concrete frame structure have good anti-seismic performance so that this
One structure type is widely used.There are three types of systems, i.e. frame, unbraced frames and Frame-Shear Wall for common frame structure
Structural system.No matter which kind of frame structure, there is frame joint.
Reinforced concrete frame node is component part important in frame structure, is portion more special in frame structure
Position, stress is more complex, and column plays the role of downward transmission internal force, and is the bearing of beam, receives this layer of beam and passes over
Moment of flexure and shearing, frame structure bean column node core space be ensure frame bearing capacity and ductility key position, node connection
Reliability have very important influence to the safety of integrality performance of the structure and structure.
It is at home and abroad found in all previous earthquake, the eaerthquake damage of frame structure mostly occurs in beam column node area.Reinforcing bar is mixed
Solidifying soil frame structure after certain service life, by natural cause, heavy duty, sound load long term, it is in addition early
The influence of construction stage phase human factor, will appear at bean column node concrete fall off, the diseases such as voids and pits.To Qingdao frame
Frame structure carries out nodal test, and testing result shows that the node there are quality problems accounts for 20% or so.In frame structure beam column section
In point, especially middle layer intermediate node is caused because two-way frame beam column reinforcing bar is anchored at from several different directions in node
The position reinforcing bar is overlapped layer by layer, and bar spacing is caused not meet code requirement；Simultaneously because concreting is difficult, vibrating spear is difficult
Effectively to vibrate, lead to node inner concrete leakiness, reduces the bond stress and adhesion strength of concrete and rebar.It is related to grind
Study carefully and be anchored in this beam steel when showing earthquake and can extract in advance, leads to structure premature failure.
Previous researcher's research is precast reinforced concrete frame node, typically such as：Guo Haishan et al. research hairs
A kind of prestressing force assembly concrete frame joint connection structure (denomination of invention is illustrated：Prestressing force assembly concrete frame section

With shearing resistance high tensile reinforcement.A kind of fully-prefabricated assembled steel tube confinement frame joint (denomination of invention has been invented in Zheng Lian fine jades et al. research：
A kind of fully-prefabricated assembled steel tube confinement frame joint, the patent No.：CN106049691A), including core space inner frame, constraint steel
Pipe and beam-ends built-in fitting, core space inner frame are installed in constraint steel pipe, and beam-ends built-in fitting is welded in outside constraint steel pipe, core space
Inner frame includes at least two diaphragm plates of spaced and parallel setting and a plurality of tendon bushes of wearing being arranged in diaphragm plate, tabula
Injected hole is provided on plate.A kind of assembled steel reinforced concrete frame node and preparation method thereof has been invented in Yao Fang brightness et al. research
(denomination of invention：A kind of assembled steel tendon concrete frame structure bean column node, the patent No.：CN107288218A), it is by prefabricated
Frame column is set a roof beam in place with prefabricated frame splices node and cast-in-place concrete composition, and the column in prefabricated frame trestle indulges muscle and stretches out structure from column top
At the reserved vertical muscle in capital, the reserved muscle periphery several node columns of setting of indulging in capital indulge muscle, and are bound with the reserved vertical muscle in capital, prefabricated frame
Set a roof beam in place splicing in prefabricated frame trestle capital, prefabricated frame set a roof beam in place in beam bottom indulge muscle to prefabricated frame set a roof beam in place spelling joint direction stretch out, wear
Cross the anchoring of splicing node straight line.A kind of concrete frame node (denomination of invention has been invented in Qu Xiushu et al. researchs：A kind of concrete
Frame joint, the patent No.：CN107012952A), which is by the way that fixing device is arranged on concrete column, coordinates prefabricated
Locking device is set on beam, and is installed on locking device and fixing device by the way that the both ends of dissipative member are detachable, to
Realize the connection between precast beam and concrete column.Zhang Min et al. has invented a kind of steel reinforced concrete frame structure (denomination of invention：
Steel reinforced concrete frame structure, patent No. CN103882993A：), it includes the profile steel concrete column being vertically arranged and lateral cloth
The drum girder steel set, profile steel concrete column include the shaped steel with section steel flange being arranged inside, and drum girder steel includes horizontal up and down
Two steel beam flanges of distribution, one end and the section steel flange of steel beam flange are rigidly connected, the connection of steel beam flange and section steel flange
The shape at end is the isosceles trapezoid of inner wide and outer narrow.
Above several technologies are all made of prefabricated assembling type reinforced concrete frame joint, although prefabricated assembled can save
Template, but globality, rigidity, poor seismic behavior；The present invention is quasi- to use cast-type reinforced concrete frame novel joint, construction
Simply, reliable in quality, and cast-type reinforced concrete structure good integrity, rigidity is big, shock resistance and good impact resistance, water proofing property
It is good, to the adaptable of concave plane.
Invention content
Based on conventional steel bar concrete frame joint bar connecting is intensive in the prior art, concreting is difficult, vibrate
Stick is difficult to effective vibration compacting, quality problems easily occurs between node.And prefabricated assembling type reinforced concrete frame joint globality,
Rigidity, poor seismic behavior, the present invention provide a kind of good integrity, and rigidity is big, and anti-knock shock resistance is good, good waterproof performance, to not advising
The then adaptable cast-type concrete frame joint of plane.
Based on this, a kind of shaped steel of present invention offer runs through the novel beam-to-column joint structure of cast-type concrete frame comprising
Girder with rolled steel section en cased in concrete and the node of profile steel concrete column, shaped steel, reinforcing bar, steel reinforced concrete node extend beam section, steel reinforced concrete
Node extends shell of column, reinforced beam and reinforced column.
Wherein, the shaped steel in the girder with rolled steel section en cased in concrete extends through node, with the reinforcing bar in reinforced beam anti-
Curved point is nearby attached.
