Native plate, partially prestressed concrete plate, steel fiber reinforced concrete slabs；Pillar is generally steel reinforced concrete rectangular column or cylinder.
The capital of concrete floor column structure is arranged in bolumn cap, for increasing column to plate rest area, when floow load is larger
When, the bearing capacity, rigidity and punch resistant capability of plate can be improved.In the concrete flat slab structure of conventional belt bolumn cap, bolumn cap section
Size is big, and cast in situs is needed to construct.
Utility model content
The utility model provides a kind of steel-concrete composite slab rod structure, replaces tradition cast-in-place using combination steelframe rest
Cap of reinforced concrete column.Steelframe rest can be mounted directly by prefabrication, scene, convenient for construction, meanwhile, utilize steel strength height
The characteristics of, effectively reduce bolumn cap size.
Used specific technical solution is as follows:
A kind of steel-concrete composite slab rod structure, including armoured concrete slab and reinforced column, the reinforced concrete
The steelframe rest for supporting the armoured concrete slab is provided at the capital of earth pillar；
The steelframe rest is formed by several joists and closing ferrule combinations, and closing cuff is around the armored concrete
Column periphery arrangement, joist extend outwardly；
The steelframe rest is supported on the bottom surface of the armoured concrete slab, and top surface and medial surface are respectively arranged with peg
It is connect with armoured concrete slab and column.
The application substitutes traditional cast in place reinforced bar coagulation in the node area of Reinforced Concrete Slab Column structure installation steelframe rest
Earth pillar cap makes full use of the high-strength performance of steel, reduces bolumn cap sectional dimension；Made by the enclosing that steelframe rest closes cuff
With sufficiently constraining column cap concrete, effectively improve node area carrier performance；Joist extends outwardly from cuff, can be according to carrying
It is required that it is sized, meanwhile, different form is selected in combination with architectural image demand.
In addition, in traditional plate-column structure, due to the influence of the cast-in-place bolumn cap in capital, because of the intercolumniation fire prevention of fire-fighting requirements setting
Roller shutter can not be installed to the top of reinforced column, cause clear height insufficient, hence it is evident that influence building function arrangement.Using this reality
With novel technical solution, sufficient space can be reserved between steelframe rest joist, accommodates the bracket and track of rolling screen door, so that volume
Curtain door can be installed to board bottom, effectively solve the problems, such as existing for traditional plate-column structure.
Preferably, corresponding with rectangle pillar, the steelframe rest is in intersecting parallels.I.e. the closing cuff is in
Rectangle, the outrigger in a direction can be linked to be on one side an integrated member with closing cuff.In intersecting parallels steelframe rest,
Space between two ipsilateral joists can install rolling screen door.In addition, corresponding to circular posts, the closing cuff can
To circularize, joist is radially welded to connect in the periphery of cuff.
Preferably, the column in the inner wall and reinforced column of the closing cuff indulges muscle overlap joint welding, the envelope
The pre- cloth peg of inner wall for closing cuff is connect with reinforced column, the pre- cloth peg in top surface and reinforcing bar of the closing cuff and joist
Concrete slab connection, in this way, effectively the shearing and moment of flexure of reinforced column can be passed to transmission plate, guarantee steelframe rest with
The integrated carrying performance of pillar, plate.
It is protruded into armoured concrete slab at the top of muscle preferably, the column is indulged, and in tri- column of thickness range Nei She
Stirrup.
Preferably, the steelframe rest closing cuff is welded using rectangular steel pipe, the joist can be adopted
With rectangular steel pipe, H profile steel, T-steel cross-section, whole steelframe rest is welded to form with closing cuff.
For the moulding needs for sufficiently meeting space, preferably, the bottom margin of the joist be oblique line shape,
Fold-line-shaped or curve are arc-shaped.
Preferably, the peg and steelframe rest are welded to connect, and it is prefabricated in the factory, wherein steelframe rest
Section, peg arrangement quantity should according to stress it needs to be determined that.
The structure of the application efficiently utilizes the height of steel relative to traditional band bolumn cap steel concrete plate structure
Epistasis energy reduces bolumn cap sectional dimension；Using combination steelframe rest, be conducive to prefabrication, in-site installation reduces live column
Cap working procedure；Overcome the problem of stopping due to traditional bolumn cap, make fire resisting shutter that can not be installed to top.
The utility model uses prefabricated peace relative to the cast-in-place bolumn cap in conventional steel bar concrete plate-column structure, steelframe rest
Dress, it is more convenient to construct, and also complies with the assembled architecture industrial policy that country advocates.
The structure of the application can undertake bigger load relative to the steel concrete plate structure without bolumn cap, right
Generally needing the big straddle rod structure of strutting cap has wider array of applicability.
On the one hand the structure of the application can be effectively reduced relative to the plate-column structure for burying fashioned iron in concrete slab, column
On the other hand the sectional dimension of plate, column reduces site operation difficulty, it is easier to guarantee node area construction quality；Node area uses
Steelframe rest is combined, closing cuff is formed to column cap region, column cap concrete is sufficiently constrained, in combination with peg connection, column
The welded connecting of vertical muscle and cuff, can greatly improve the load-carrying properties in node area, promote the safe bearing load performance of plate-column structure.
