Abstract
The utility model discloses an annular plate node of a steel pipe concrete column and a bonded prestress steel bar concrete beam. The annular plate node comprises the steel pipe concrete column 1, the bonded prestress steel bar concrete beam 2, a steel bar concrete annular beam 3, a steel reinforcing ring plate 6, a stiffening plate 8 and a non-prestress steel bar 9. After the non-prestress steel bar 9 is welded with the stiffening plate 8, frame column and frame beam penetrating prestress ribs 4 are connected together with the steel pipe concrete column 1 through pipe wall holes 7 in the steel pipe concrete column in the vertical direction, and frame column winding prestress ribs 3 surround the steel pipe concrete column 1 and are anchored on the steel reinforcing ring plate 6 through tension ends 5. According to the annular plate node of the steel pipe concrete column and the bonded prestress steel bar concrete beam, the bonded prestress ribs can avoid excessive weakening of the section of a steel pipe column and are connected with the steel pipe column reliably, power transmission is clear, construction is convenient, and meanwhile the annular plate node not only can serve as side column nodes in a framework beam structure, but also can serve as middle column nodes and can be widely applied to high-rise, long-span, heavy-load and anti-seismic areas.
Description
Technical field
The utility model relates to the structure field in the civil engineering, particularly a kind of steel core concrete column and bonded prestress reinforced concrete beam ring flat-plate node.
Background technology
In civil construction project, use the history in existing more than 80 year of steel core concrete column, China is from nineteen fifty-nine begin one's study performance and the application of steel core concrete column, steel core concrete column has high strength, superior performance, characteristics such as easy construction, the advantage of traditional member structure system is further brought into play, especially at high level, stride greatly, in the building of heavy duty and antidetonation, can satisfy a series of requirements of design and construction preferably, and the bonded prestress concrete beam can reduce sectional dimension satisfying as far as possible under the prerequisite of requirement for bearing capacity, save architectural space, steel core concrete column and bonded prestress concrete beam structural system have broad application prospects thus, can in the highrise building of building field and large-span space structure, be extensive use of, the validity that steel core concrete column is connected with the bonded prestress concrete beam is the integrally-built rigidity of influence directly, stablize and supporting capacity, also have influence on site operation difficulty and construction speed, because bonded prestress reinforcing bar bellows diameter is bigger, when existing difficulty to wear steel pipe column or prick post the steel pipe column cross section is weakened bigger problem, so far our country does not also have perfect design of node and theory of construction, and does not have the ring flat-plate node connected mode of steel core concrete column and bonded prestress reinforced concrete beam.
The utility model content
At the problem that prior art exists, the utility model aims to provide a kind of steel core concrete column and bonded prestress reinforced concrete beam ring flat-plate node.
The utility model provides a kind of steel core concrete column and bonded prestress reinforced concrete beam ring flat-plate node, comprise steel core concrete column 1, bonded prestress cast-in-situ steel reinforced concrete beam 2, enforced steel loop 6, stiffener 8, nonprestressed reinforcement 9, wear frame column presstressed reinforcing steel 4 in the described bonded prestress cast-in-situ steel reinforced concrete beam 2 and run through described steel core concrete column 1 and be connected with described enforced steel loop plate 6, walk around described steel core concrete column 1 around frame column presstressed reinforcing steel 3 in the described bonded prestress cast-in-situ steel reinforced concrete beam 2 and be connected with described enforced steel loop 6.
Preferably, described nonprestressed reinforcement 9 is welded on the stiffener 8.
Preferably, have pipe tap 7 on the described steel core concrete column 1.
