Description
Technical field
The utility model belongs to technical field of buildings, particularly a kind of prefabrication and assembly construction profile steel concrete column skeleton.
Background technology
Steel reinforced concrete structure (be often translated into Steel Reinforced Concrete Structure, be called for short SRC structure) refers to the steel-concrete combined structure form configuring shaped steel and formed in reinforced concrete member cross section.Compared with reinforced concrete structure, owing to configuring shaped steel in reinforced concrete section inside, steel reinforced concrete structure has the significant advantages such as intensity is high, rigidity is large, anti-seismic performance is good, sectional dimension is little.Because shaped steel outer wrap has steel concrete compared with steel work, the outstanding advantages such as steel reinforced concrete structure has that cost is low, rigidity is large, fire resistance and excellent in durability.Therefore, from the generalized analysis of the aspects such as financial cost, stress performance, endurance quality and fire resistance, steel reinforced concrete structure has the advantage of both reinforced concrete structure and steel work concurrently, has remarkable performance advantage.
Current steel reinforced concrete structure is mainly used in some large-scale super highrise building and large span architectures, as Shanghai Jin Mao Tower, Shanghai World Financial Center, CCTV Xin Tai location, the engineerings such as international trade three phase main building all adopt the current steel reinforced concrete structure of steel reinforced concrete structure to be mainly used in some large-scale super highrise building and large span architectures, as Shanghai Jin Mao Tower, Shanghai World Financial Center, CCTV Xin Tai location, the engineerings such as international trade three phase main building all adopt steel reinforced concrete structure, and in the general highrise building had a large capacity and a wide range and multistory building less use steel reinforced concrete structure, one of its main reason is exactly that steel reinforced concrete structure on-site construction processes is various and structure connects complicated.Just because of steel reinforced concrete structure construction this outstanding shortcoming complicated, cause steel reinforced concrete structure to be applied and be subject to very big restriction, cause the combination property of steel reinforced concrete structure excellence to be not in full use.
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 prefabrication and assembly construction profile steel concrete column skeleton, based on the thought that partial precast assembled portion is cast-in-place, the utility model belongs to the outside frame portion of the PSRC post be prefabricated in the factory, can install at building-site, last and beam, plate together whole boring part of watering PSRC post, be suitable for different project situation demand, has 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 prefabrication and assembly construction profile steel concrete column skeleton, comprise high performance concrete skeleton 1, high performance concrete skeleton 1 is the column structure of hollow, some vertical muscle 2 and some shaped steel 3 is provided with along its length in high performance concrete skeleton 1, wherein, vertical muscle 2 embeds in the sidewall of high performance concrete skeleton 1, shaped steel 3 is arranged in the center cavity of high performance concrete skeleton 1 and is fixed on the sidewall of high performance concrete skeleton 1, circumference along high performance concrete skeleton 1 is provided with some equally spaced stirrups 4, and vertical muscle 2 and shaped steel 3 are all positioned among the encirclement of stirrup 4.
Described shaped steel 3 is i iron.
To be that cross is staggered by two i iron formed described shaped steel 3.
Described shaped steel 3, on column length direction, stretches out the two ends of prefabricated high performance concrete hollow column 1.
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 precasting steel frame part completes, in building site by being directly connected with node or steel column by the shaped steel of pre-erection (or being connected with concrete column transition), more namely concreting boring part completes the construction and installation of PSRC post.Compared with the construction and installation of traditional SRC post, on-the-spot without temporary support under assembling reinforcement, formwork, form removal and erection post.Through appropriate design, the construction and installation of PSRC 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 PSRC 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.
4) construction quality is good.In the construction of traditional SRC post, because SRC post working procedure is many, difficulty of construction large, often to occur in SRC column web that concrete vibrating is poor, the quality problems such as misplace of rebars in Concrete intensity insufficient and post, construction quality is wayward.And in PSRC post, the frame portion of PSRC post is prefabrication, and concreting is vibrated convenient and can be adopted stream curing, and concrete construction quality is easy to control, especially, time for employing high performance concrete, PSRC post advantage in quality control on construction is more obvious.
Generally speaking, adopt the PSRC post of prefabrication and assembly construction technology compared with traditional SRC post, simplify working procedure and difficulty of construction, effectively can solve the crucial problem that the traditional SRC post of long-term restriction is applied, and can give full play to and effectively promote the significant advantage of traditional SRC post 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 PSRC post and have practical meaning in engineering to promote it to apply.
