Description
Technical field
The utility model belongs to technical field of buildings, particularly a kind of precast and assembled reinforced concrete spinous process of the seventh cervical vertebra frame.
Background technology
In modern reinforced concrete structure, most widely used form of structure is the earliest used to be monolithic 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, adaptive capacity built flexibly to out-of-shape and space also very strong simultaneously.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, and material usage is many, and the cycle is long, high in cost of production, does not play positive impetus for establishing resource economy type and friendly environment society.
Therefore along with the development of building construction technology, be there is development in prefabricated concrete structure.It is the concrete structure being coagulated native component or parts assembly connection by concrete.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 precast and assembled reinforced concrete spinous process of the seventh cervical vertebra frame, based on the thought that partial precast assembled portion is cast-in-place, the utility model belongs to the outside frame portion be prefabricated in the factory, can install at building-site, and water with beam, plate are together whole, be suitable for different project situation demand, there is the feature of easy construction, with low cost, function admirable.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of precast and assembled reinforced concrete spinous process of the seventh cervical vertebra frame, comprise high performance concrete skeleton 1, high performance concrete skeleton 1 is the column structure of hollow, some vertical muscle 2 are provided with along its length in high performance concrete skeleton 1, in high performance concrete skeleton 1, its cross-sectional direction is provided with some reinforcing bars 3 and stirrup 4, vertical muscle 2 and stirrup 4 embed in the sidewall of high performance concrete skeleton 1, vertical muscle 2 is positioned among the encirclement of stirrup 4, reinforcing bar 3 strides across the center cavity of prefabricated high performance concrete hollow column 1, and the termination of reinforcing bar 3 is connected to the inner side of stirrup 4.
Described vertical muscle 2 is at least arranged at the link position of reinforcing bar 3 and stirrup 4.
Described stirrup 4 is welding compound stirrup or continuous helical high-strength stirrup.
Compared with prior art, the beneficial effects of the utility model are:
1) each component can prefabricatedly complete, and field combinations uses.Both can ensure globality, greatly improve anti-seismic performance again.
2) easy construction.The production that is all prefabricated in the factory of precast reinforced skeleton part completes, in building site by being directly connected with node or steel column by the reinforcing bar of pre-erection (or being connected with concrete column transition), more namely concreting boring part completes reinforced concrete post construction and installation.Compared with conventional post construction and installation, on-the-spot without temporary support under assembling reinforcement, formwork, form removal and erection post.Through appropriate design, the construction and installation of reinforced concrete post will be same with steel column convenient and quick, and workability will greatly improve.
3) functional promotion.Can adopt high performance concrete at pre-erection, 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 post when floorslab concrete is selected, select all kinds concrete of different qualities, effective lift structure using function demand.Such as the cast-in-place part concrete of reinforced concrete post, be the energy that economizes on resources, can regeneration concrete be adopted; For alleviating deadweight, light weight aggregate concrete can be adopted; For improving shock-absorption sound-insulation effect, rubber concrete or sound absorption concrete can be adopted; For improving heat-insulating property, thermal-insulating concrete can be adopted.
3) construction quality is good.In conventional post construction, because post working procedure is many, difficulty of construction is large, often to occur in column web that concrete vibrating is poor, the quality problems such as misplace of rebars in Concrete intensity insufficient and post, and construction quality is wayward.And in the prefabricated reinforced concrete post of the utility model, the frame portion of reinforced concrete post is prefabrication, concreting is vibrated convenient and can be adopted stream curing, concrete construction quality is easy to control, especially, time for employing high performance concrete, reinforced concrete post advantage in quality control on construction is more obvious.
Generally speaking, adopt the reinforced concrete post of prefabrication and assembly construction technology compared with conventional post, simplify working procedure and difficulty of construction, can give full play to and the significant advantage of effective lifting column in stress performance, endurance quality, fire resistance and economic performance etc., can be widely used in all kinds of steel concrete and steel building, be particularly useful for large span, heavy load or complexity, irregular highrise building and super highrise building.Therefore, further investigation is carried out to prefabricated reinforced concrete column of the present utility model and have practical meaning in engineering to promote it to apply.
