As preferably, groove is the groove of U-type groove, V-groove or circular arc type.
A kind of prefabricated assembled concrete framework applying above-mentioned precast concrete column, including at least two coagulation soil matrix Plinth, concrete foundation centre is provided with fourth hole, and its end face center is provided with groove, and concrete column is vertically placed in mixed On solidifying earth foundation, the projection of concrete column bottom and the fit depressions of concrete foundation end face, fourth hole and the first through hole Inside it is provided with stretching rope concrete foundation and concrete column being fixed together;Concrete in two adjacent concrete foundations Being provided with beams of concrete between post, beams of concrete two ends are arranged on bracket, and beams of concrete is provided with third through-hole along centrage, and the 3rd Through hole aligns with the second through hole, be provided with in third through-hole and the second through hole beams of concrete and concrete column are fixed together Drag-line.
As preferably, the inwall of third through-hole is corrugated tube.
As preferably, at least provided with two concrete columns in concrete foundation, between concrete column, first place connects.
As preferably, stretching rope is reinforcing bar, steel strand wires, synthetic fiber cable, rustless steel pull bar or marmem rope.
The beneficial effects of the utility model are:
One: this utility model is provided with through hole at precast concrete column center, can be used to carry out stretch-draw during assembling at the scene, Make precast concrete column internal generation prestressing force, its deformation and amount of deflection can be greatly reduced.
Two: the through hole at precast concrete column center of the present utility model is formed by corrugated tube, works as precast concrete During post stress, this structure can more adapt to the change of shape, and stress is the most reasonable.
Three: this prefabricated assembled concrete framework of the present utility model, use post stretching to carry out stretch-draw, there is construction party Just, the feature of short construction period, low cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of precast concrete beam;
Fig. 2 is the structural representation of precast concrete column;
Fig. 3 is the structural representation of precast concrete framework;
In figure: 1 beams of concrete 2 first through hole 3 corrugated tube 4 concrete column 5 bracket 6 stretching rope 7 concrete foundation Protruding 11 second through hole 12 third through-holes of 8 stretch-draw anchor 9 grooves 10.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
Embodiment one
As in figure 2 it is shown, concrete column 4 is provided with the first through hole 2 along centrage, the inwall of the first through hole 2 is corrugated tube 3, Before producing precast concrete column, first embedding good corrugated tube 3, the diameter of corrugated tube 3 is larger than presstressed reinforcing steel (i.e. stretching rope) Diameter, then casting concrete vibrates maintenance molding.Top outside concrete column 4 is provided with bracket 5, and concrete column 4 is upper Be provided with the second through hole 11 that left and right is penetrating in the top position of bracket 5, the top of concrete column 4 is provided with groove 9, concrete column 4 Bottom be provided with the projection 10 matched with groove 9.Groove 9 is the groove of U-type groove, V-groove or circular arc type.
As it is shown on figure 3, a kind of prefabricated assembled concrete framework applying above-mentioned precast concrete column, including at least two Concrete foundation 7, concrete foundation 7 centre is provided with fourth hole, and its end face center is provided with groove 9, concrete column 4 Vertically being placed in concrete foundation 7, the projection 10 of concrete column 4 bottom matches with the groove 9 of concrete foundation 7 end face, It is provided with, in fourth hole and the first through hole 2, the stretching rope 6 concrete foundation 7 and concrete column 4 being fixed together;Two adjacent Concrete foundation 7 on concrete column 4 between be provided with beams of concrete 1, beams of concrete 1 two ends are arranged on bracket 5.Such as Fig. 1 Shown in, beams of concrete 1 is provided with third through-hole 12 along centrage, and third through-hole 12 aligns with the second through hole 11, third through-hole 12 and The stretching rope 6 beams of concrete 1 and concrete column 4 being fixed together it is provided with in second through hole 11.
The inwall of third through-hole 12 is corrugated tube 3.At least provided with two concrete columns 4, concrete column in concrete foundation 7 Between 4, first place connects.Stretching rope 6 is reinforcing bar, steel strand wires, synthetic fiber cable, rustless steel pull bar or marmem rope.Stretch-draw The two ends of rope 6 are equipped with stretch-draw anchor 8, and its effect is to be fixed it, produce prestressing force.Stretch-draw anchor 8 is separately positioned on and goes up most Concrete column 4 end face in face, the bottom surface of concrete foundation 7 and framework outermost concrete column 4 side, for fixed lateral With vertical stretching rope 6.
After preset component is transported to job site, first carry out the stretch-draw of precast concrete column component.Pillar by each layer After placing, by stretching rope through reserving hole (i.e. each through hole), carry out stretch-draw with the tension ground tackle fixed.Laggard The stretch-draw of row beams of concrete, first places beam, allows stretching rope along reserving hole through beam, then anchorage is fixed it After carry out stretch-draw.So far frame beam column structure stretch-draw completes.Finally precast floor slab is placed, prestressing force precast concrete framework Shaping structures.
Embodiment two
In the present embodiment, the difference with embodiment one is, precast concrete beam is at reserved stretch-draw hole (i.e. third through-hole) Time want arch camber, springing height is the 1/1000~3/1000 of beam span.The purpose of do so is to offset load pair to a certain extent The pressure of beam so that bearing capacity is higher.
Remaining is with embodiment one.
Certainly, foregoing is only preferred embodiment of the present utility model, it is impossible to be considered for limiting utility model Scope of embodiments.This utility model is also not limited to the example above, and those skilled in the art are in this practicality Impartial change and the improvement etc. made in novel essential scope, all should belong to this utility model patent covering scope.
