Description
Technical field
The present invention relates to building engineering field, in particular to Punching Shear concrete rectangular column plate node and concrete
Plate node.
Background technology
Steel reinforced concrete structure has the advantage of steel construction and concrete structure concurrently, possess higher bearing capacity and rigidity,
Good earthquake ductility and energy dissipation capacity, are adapted in skyscraper and greatly across popularization and application in heavy structure.With house, office
Etc. the development of business skyscraper, people meet vision sight, building function in the urgent need to higher architecture indoor headroom, disappeared
The requirement such as anti-function and traditional architecture art of geomantic omen, therefore, flat slab system arises at the historic moment.Plate-column structure is used as arch without beam
A class in system, its good globality, open space and considerable economic benefit are increasingly by people
Concern.But this class formation by violent earthquake when acting on, the additional stress as caused by unbalanced moment can be on post periphery
Enlarge-effect is produced, when shear stress is excessive and lacks effective shearing resistance measure, it is most likely that be punched at slab-column connections
Destruction, even results in the Progressive Collapse of structure.For beam-plate-column structure system, the presence of beam can effectively adjust section
Moment of flexure and shearing at point, while having certain rigid constraint to node.Therefore, the anti-seismic performance of slab-column connections not as good as beam-
The anti-seismic performance of plate-Column border node.In fact, the Punching Shear problem of slab-column connections is the weak link in whole system.It is general and
Speech, by setting cap or the contact area set up between supporting plate and then development column and plate to can be used to alleviate post to plate in capital
Punching behavior, but set cap or supporting plate to be inappropriate as a rule, such as in apratment building, supporting plate hinders sight
Look forward or upwards.In addition, cap or supporting plate equally can be to reinforcing bar colligation and formwork make troubles.Therefore, in the state of the art, mostly
The Punching Shear of slab-column node in slab-column structure is solved the problems, such as using the method for configuration bent-up bar.
Profile steel concrete column-hardened structure is as a class branch of steel reinforced concrete structure, and it can meet vertical pressure well
Curved component is to high building structure bearing capacity and the demand of anti-seismic performance, while the structure type of arch without beam also can guarantee that and build
Build effective performance of function.Therefore, profile steel concrete column-hardened structure can as high-rise large bay structure preferred forms.Consider
Be configured with more shaped steel into profile steel concrete column, and conventional shaped-steel layout Shaped Steel has a longer edge of a wing, and with post side
Parallel arrangement, therefore be difficult to adopt conventional meanses and penetrate bent-up bar in post, so for, seek a kind of simple structure, apply
The convenient rational Punching Shear part of power transmission again of work seems particularly necessary.
The content of the invention
It is an object of the invention to provide a kind of Punching Shear concrete rectangular column plate node, it can increase connects with floor
Contacting surface is accumulated, and reduces stress concentration phenomenon；Bearing capacity, increase drawknot effect etc. can also be improved.
Another object of the present invention is to provide a kind of concrete slab node, its simple structure, convenient, cost of constructing are relatively low
And power transmission is rationally, can strengthen the punch resistant capability between concrete floor and Punching Shear concrete rectangular column plate node.
What embodiments of the invention were realized in：
A kind of Punching Shear concrete rectangular column plate node, it includes rectangular concrete column and formed steel construction, formed steel construction bag
Include steel column, four steel plates and four doughnut-shaped steel plates, the adjacent steel plate of each two connects a doughnut-shaped steel plate, steel column includes the
One web and the second web, the first web and the second web are arranged in a crossed manner, the two ends of the two ends of the first web and the second web
The edge of a wing is provided with, each edge of a wing connects a steel plate；Rectangular concrete column is connected to steel column.
In preferred embodiments of the present invention, above-mentioned steel plate includes the first steel plate and the second steel plate, doughnut-shaped steel plate connection phase
Adjacent two the first steel plates, the second steel plate is connected to side wall of first steel plate towards steel column short transverse, and steel plate section forms " T "
Font.
In preferred embodiments of the present invention, the length direction of the second steel plate is provided with least one peg.
In preferred embodiments of the present invention, the junction on above-mentioned first steel plate and the edge of a wing is provided with ribbed stiffener, and puts more energy into
Rib is arranged at side of first steel plate away from the second steel plate.

Again to 1.5 times of thickness of concrete floor 820, the thickness of the concrete floor 820 refers to the thickness of steel column 300a axis directions.
Yet further, the diameter that the annulus set is enclosed between doughnut-shaped steel plate 500 and steel plate 400a is more than aforementioned rectangular coagulation
Width of the earth pillar 810 in horizontal plane.
Foregoing concrete floor 820 is connected to steel plate 400a, and the lower surface of concrete floor 820 can be with the first steel
Plate 410a lower surface is arranged at same level (holding is flushed), and the second steel plate 420a is embedded at concrete floor 820
Inside, i.e. steel plate 400a are to be arranged in inverted " T " word state inside concrete floor 820；The purpose of above-mentioned set-up mode
It is the bearing capacity for farthest playing concrete, i.e. concrete floor 820 is supported directly on post, and load is passed by floor
The T-shape steel plate 400a spliced after to post by doughnut-shaped steel plate 500 Undertaking effect effectively delays punching behavior, the ring of circular arc
The steel plate 400a that shape steel plate 500 splices has the trend mutually extruded in concrete floor 820 under punching load effect.Specifically
Ground, height of the steel plate 400a in the section of its short transverse is less than or equal to the half of the thickness of the concrete floor 820, to ensure
The hidden effect of pipeline etc. is laid in plate.
It should be noted that when if the steel bar stress of the bottom of concrete floor 820 needs to be arranged at steel plate 400a, Ke Yishi
Steel bar stress is blocked and is welded on steel plate 400a the second steel plate 420a, the second steel plate 420a in steel plate 400a is can also be
Upper perforation, then steel bar stress is arranged in the hole.
It should be further stated that, the shape of above-mentioned concrete floor 820 can be square, but be not limited only to this,
In other embodiments, the other shapes such as circle be can also be.
Concrete slab node 10a beneficial effect is：The circular arc doughnut-shaped steel plate that the concrete slab node 10a passes through arrangement
The section of 500 splicings is in the steel plate 400a of T-shape, and the contact between reinforced steel column 300a and concrete floor 820 is not changing
Become on the basis of original design construction on slab-column connections with regard to Punching Shear concrete rectangular column plate node 100 and concrete can be strengthened
Punch resistant capability between floor 820；Meanwhile, either manufacture and design on still construction formwork, the doughnut-shaped steel plate 500 of circular arc
The steel plate 400a and steel column 300a of the T " types of splicing connection are foolproof, while can also farthest play mixed
Coagulate the characteristics of soil bearing capacity is good；Concrete slab node 10a can apply to steel reinforced concrete frame flat slab system
King post joint.
Embodiment two
Fig. 4 is refer to, the present embodiment provides a kind of concrete slab node 10b, its concrete slab provided with embodiment one
