Description

With the U-shaped beam of prefabricated reinforced concrete of horizontal high-strength concrete dividing plate
Technical field
The utility model belongs to technical field of buildings, relates to building unit, particularly a kind of U-shaped beam of prefabricated reinforced concrete with horizontal high-strength concrete dividing plate.
Background technology
Monolithic reinforced concrete structure in modern reinforced concrete structure, it is formwork the structure of monobloc cast at the scene, there is the advantages such as overall performance is good, rigidity is large, barrier properties is good, but in use also have a lot of shortcomings, as carried out formwork and construction at the scene, working procedure is various, labo r usage is large, material usage is many, and the cycle is long, high in cost of production.Therefore, be there is development in prefabricated concrete structure.The making of building unit can be made not by impact and the restriction in season relative to cast-in-place concrete structure fabricated construction, realize suitability for industrialized production, because component carries out building and maintenance in factory, the quality of component is ensured, and substantially reduce the construction period, accelerating construction progress, has saved a large amount of shuttering supportings, but it also also exists many shortcomings simultaneously, overall performance is poor, impervious poor, unfavorable antidetonation, also has certain deficiency in use and aesthetic.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of U-shaped beam of prefabricated reinforced concrete with horizontal high-strength concrete dividing plate, without the need to setting up temporary support, easy construction, and deadweight is less, supporting capacity is strong, corrosion resistance and good, there is structure simple, feature easy to use.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of U-shaped beam of prefabricated reinforced concrete with horizontal high-strength concrete dividing plate, comprise the high-strength concrete skeleton 1 that cross section is U-lag, the some horizontal high-strength concrete dividing plate 2 vertical with flute length direction and the some closed stirrup 3 vertical with flute length direction is provided with in high-strength concrete skeleton 1, the bottom of stirrup 3 is arranged in cell wall and the bottom land of high-strength concrete skeleton 1, top is unsettled, the bottom welding of stirrup 3 has some vertical muscle one 5 parallel with flute length direction, and the welded top of stirrup 3 has some vertical muscle two 4 parallel with flute length direction.
The groove two ends of described high-strength concrete skeleton 1 are respectively arranged with concrete rubber core.
Compared with prior art, the beneficial effects of the utility model are:
1) each component can prefabricatedly complete, and field combinations uses, with floor monobloc cast together with post.Both can ensure globality, greatly improve anti-seismic performance again.
2) U-shaped skeleton can play template action, adopts the U-shaped skeleton of high-strength concrete to have very large rigidity, therefore, without the need to setting up temporary support, and easy construction.
3) lifting is convenient, due to the U-shaped section form adopted, reduces concrete consumption, significantly alleviates the deadweight of prefabricated units; Lateral partitions plays the destruction of preventing to produce because side direction moment of flexure is excessive in hoisting process simultaneously.
4) relative to traditional fabricated construction, overall performance is good.After assembling U-shaped skeleton, beam, plate, post are built in the lump.Impervious and anti-seismic performance all with significantly promotes, and also meets the requirement using aesthetic simultaneously.
5) flexible design, the horizontal concrete diaphragm of employing effectively can prevent longitudinal bond-slip of new-old concrete, adopts high-strength concrete at pre-erection simultaneously, and cast-in-place part adopts regular tenacity concrete, and the two strength grade of concrete can be different.Floorslab concrete can not limit by concrete strength in beam when selecting, and selects all kinds concrete of different qualities, effective lift structure using function demand.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with drawings and Examples.
A kind of U-shaped beam of prefabricated reinforced concrete with horizontal high-strength concrete dividing plate of the utility model, comprise the high-strength concrete skeleton 1 that cross section is U-lag, in high-strength concrete skeleton 1, be provided with the some horizontal high-strength concrete dividing plate 2 vertical with flute length direction and the some closed stirrup 3 vertical with flute length direction.The bottom of stirrup 3 is arranged in cell wall and the bottom land of high-strength concrete skeleton 1, and top is unsettled, and the bottom welding of stirrup 3 has some vertical muscle one 5 parallel with flute length direction, and the welded top of stirrup 3 has some vertical muscle two 4 parallel with flute length direction.The groove two ends of high-strength concrete skeleton 1 are respectively arranged with concrete rubber core.
The utility model high-strength concrete skeleton 1, horizontal high-strength concrete dividing plate 2, stirrup 3, vertical muscle 1 and vertical muscle 24 are disposable pre-formed in factory, after stirrup 3 welds with vertical muscle 1 and vertical muscle 24, the bottom of stirrup 3 is imbedded in high-strength concrete skeleton 1 together with vertical muscle 1 and horizontal high-strength concrete dividing plate 2.Shaping skeleton is transported to job site and post, plate splice, at U-shaped skeleton empty stomach portion and its upper floor concreting in the lump.
For ease of processing, the quantity and spacing of horizontal high-strength concrete dividing plate 2 all can be evenly arranged by certain size.
The high-strength concrete cage of reinforcement part of the beam prefabricated band lateral partitions that the utility model adopts and U-shaped web comprises beam bottom and indulges stirrup and bottom high-strength concrete in muscle, beam, the production that is all prefabricated in the factory of this part completes, pass through the reinforcing bar of pre-erection and post in building site, more namely concreting floor completes beam construction and installation.On-the-spot without temporary support under assembling reinforcement, formwork, form removal and erection beam.If floor adopts compressed steel gusset-concrete combined board or laminated floor slab, then in whole floor construction process all without the need to formwork, form removal and temporary support, on-site construction processes, construction material and construction all greatly reduce man-hour.
The utility model construction quality is good, the web part of beam is prefabrication, concreting is vibrated convenient and can be adopted stream curing, concrete construction quality is easy to control, the concrete lateral partitions adopted in U-type groove can prevent the longitudinal shear slippage between new-old concrete effectively, especially, time for employing high-strength concrete, in quality control on construction, advantage is more obvious.
The utility model can adopt high-strength concrete at pre-erection in beam, and cast-in-place part adopts regular tenacity concrete, and the two strength grade of concrete can be different.Therefore, in practical engineering application, can not limit by concrete strength in beam when floorslab concrete is selected, select all kinds concrete of different qualities, effective lift structure using function demand.Such as, for cast-in-place part concrete and floorslab concrete, be the energy that economizes on resources, can regeneration concrete be adopted; For alleviating superstructure deadweight, light weight aggregate concrete can be adopted; For improving superstructure shock-absorption sound-insulation effect, rubber concrete or sound absorption concrete can be adopted; For improving superstructure heat-insulating property, thermal-insulating concrete can be adopted.
