Description
Technical field
The invention belongs to the realm of building construction, especially a kind of Punching Shear column connects node.
Background technology
At present, the construction method through being combined frequently with beam column built from concrete in construction, i.e., constitute in crossbeam and column
Frame structure on casting concrete.But the concrete structure for having beam can make it that floor makes only in the case of identical floor height
Reduced with height.With the appearance without beam concrete structure, its structure is simplified, increases and built rapidly using the advantage in space
Teacher and the favor of owner, have obtained extensive construction application.
On the one hand, slab thickness is relatively thin in no beam concrete structure, and cutting-bearing capacity is weaker；On the other hand, no beam is mixed
The diameter of Xtah Crude Clay structure central post is smaller, and then the sectional area of the column is smaller, is unfavorable for carrying more punching stress.It is existing
Have in technology, in order to which the flush shear force for carrying no beam concrete structure is added using thickening concrete floor or in floor mostly
Shaped steel, to increase the bearing capacity of its Punching Shear.But, the deadweight of no beam concrete structure, therefore its can be increased by thickening floor
Flush shear force increases therewith；Difficulty of construction can be increased by adding shaped steel, increase cost.
In summary, in the prior art, the construction method of no beam concrete is taken to have the disadvantages that：1st, floor is increased
Thickness, the deadweight for increasing structure；2nd, construction method complexity, cost are higher.

Plane where fixed disk is parallel, the two ends of the second reinforcing bar body respectively with one end of the first reinforcing bar body and the described 3rd
The bearing of trend of the other end connection of reinforcing bar body, the first reinforcing bar body and the 3rd reinforcing bar body is parallel to each other, the column
It is fixedly connected through second fixed disk with first fixed disk.
Further, the angle between the first reinforcing bar body and the second reinforcing bar body is 135 °, second reinforcing bar
Angle between body and the 3rd reinforcing bar body is 45 °.
Further, circumference of several the described punching shear reinforcements along first fixed disk is in " radial " arrangement, phase
Angle between adjacent two punching shear reinforcements is identical.
Further, the punching shear reinforcement is at least 4.
Further, first fixed disk and the second fixed disk shape of cross section are all circle, and described second consolidates
The diameter of price fixing is more than first fixed disk.
Further, some ribbed stiffeners are provided between first fixed disk and second fixed disk, it is each described to add
Strength rib is fixedly connected with first fixed disk, second fixed disk and the column respectively.
Further, section shape of the ribbed stiffener along column axial direction is right-angled trapezium, the right-angled trapezium
It is fixedly connected between " height " and the column, it is fixed between the right-angled trapezium length short " base " and first fixed disk
Connection, is fixedly connected between " base " of the right-angled trapezium length length and second fixed disk.
Further, the angle between the two neighboring ribbed stiffener is identical.
Further, the ribbed stiffener also include the first passage, first passage be arranged on the ribbed stiffener with
At the part of the column and second fixed disk connection.
Further, second fixed disk also includes some second passages, and second passage is evenly distributed on
On second fixed disk.
Compared with prior art, a kind of Punching Shear column disclosed by the invention connects node and had the advantages that：
1st, simple in construction, deadweight is smaller can be reduced because of the flush shear force that floor construction is conducted oneself with dignity and produces.

At the part being connected with the fixed disk 3 of column 4 and second, using this design, on the one hand avoid in concreting, due to mixed
The reason such as solidifying soil stirring is uneven, concrete particle is larger, speed of perfusion is too fast column 4, the fixed disk 3 of ribbed stiffener 5 and second it
Between produce hole；Floor bar 8 in another aspect floor 7 may pass through ribbed stiffener 5, floor bar 8 and column concrete structure
Connection it is more firm.
Preferably, the second fixed disk 3 also includes some second passages 31, and the second passage 31 is evenly distributed on second and consolidated
On price fixing 3, using this design, it effectively prevent in concreting process because concrete stirring is uneven, concrete
The grain hole that reason produces in one side of second fixed disk 3 away from the first fixed disk 1 such as larger, speed of perfusion is too fast.
To sum up, node, including the first fixed disk, the second fixed disk, anti-impact are connected the invention provides a kind of Punching Shear column
Reinforcing bar and column are cut, the structure design of punching shear reinforcement is improved, the carrying energy of concrete floor Punching Shear can be strengthened
