Abstract

The invention discloses a prefabricated reinforced concrete column and column splice joint adopting connection of embedded corrugated sleeves and high-strength reinforcement. The splice joint mainly comprises a prefabricated reinforced concrete upper column, a prefabricated reinforced concrete lower column, steel sleeves, the embedded corrugated sleeves and the high-strength reinforcement. An installation method of the splice joint comprises the following steps: in a factory, realizing the embedded high-strength reinforcement by a method of firstly pouring non-shrinkage self-compacting high-strength concrete into the embedded corrugated sleeves of the prefabricated reinforced concrete upper column and then inserting the high-strength reinforcement; and at the construction site, grouting the corrugated sleeves of the reinforced concrete lower column, inserting the embedded high-strength reinforcement of the upper column in the corrugated sleeves of the lower column and simultaneously welding the steel sleeve joint parts on the outer surfaces of the columns, thus realizing prefabricated reinforced concrete column and column splicing. The splice joint has the beneficial effects that all the used components are assembled and connected on the site, thus reducing reinforcement assembling and formwork supporting on the site, improving the building industrial assembly efficiency and reflecting the novel building concepts of environment friendliness and energy saving of building components.

Description

A kind of assembled steel reinforced concrete column with well and post splice node
Technical field
The invention belongs to engineering structure technical field, it is particularly applicable to armored concrete in many high level assembled arthitecutral structures Splicing field of operation in scene between post and post.
Background technology
, mainly based on site operation, this traditional mode of production industrialization degree is not high, design for China's construction Build that more extensive, building products quality is unstable, construction efficiency is low, amount of labour demanded is big, spillage of material and building waste Amount is big, resource is larger with energy resource consumption it is impossible to meet the Sustainable Development Construction about energy-conserving and environment-protective for national " 13 " planning Require.
With the quickening of China's " building industrialization, housing industrialization " process, the trend day of housing industry industrialization gets brighter Aobvious, architecture production mode is also carrying out a revolution, gradually expands the construction of novel fabricated building, novel fabricated The application of reinforced concrete structure becomes one of current research focus again.Prefabricated reinforced concrete column has product quality can Control, environmental protection, obvious economic, greatly shorten duration and easy construction.In consideration of it, seeking that a kind of construction speed is fast, building Build the structural system that the novel reinforced concrete post of material recoverable is connected with post, play the advantage of fabricated construction, with Meet building industrialization and the problem of energy-conserving and environment-protective demand is also more and more prominent.Inventor is to reinforced column and post splicing section Point has made intensive studies, and then has this case to produce.
Content of the invention
The invention provides a kind of install convenient efficiently, simple structure, the assembled steel reinforced concrete column of energy-conserving and environment-protective with The splicing node of post.
The present invention is achieved by the following technical solutions:
The invention provides a kind of assembled steel reinforced concrete column using pre-buried corrugated bushing and high tensile reinforcement and post Splicing node.Main inclusion prefabricated reinforced concrete upper prop, lower prop, steel thimble, pre-buried corrugated bushing and pre-buried high tensile reinforcement, its It is characterised by indulging in armored concrete upper prop down cross-sectional and passes through the pre-buried high tensile reinforcement of corrugated bushing in the range of muscle, and mix in reinforcing bar Solidifying soil lower prop cross section indulges pre-buried corrugated bushing in the range of muscle, and, with reserving hole, scene pours in the pre-buried corrugated bushing of lower prop After mortar, pre-buried for upper prop high tensile reinforcement is inserted in lower prop corrugated bushing to realize splicing.Meanwhile, in upper prop and lower prop stitching section The outer surface of position puts steel thimble, is welded to connect upper and lower steel thimble after grouting insertion high tensile reinforcement.
Further, pre-buried high tensile reinforcement and corrugated bushing should be arranged on upper lower prop same position indulge identical in the range of muscle Position, to ensure that indulging muscle up and down does not misplace, and is easy to scene grouting insertion.
Further, in order to the shear-carrying capacity ensureing high tensile reinforcement can play one's part to the full, perpendicular to mast axis side To the spacing of pre-buried corrugated bushing should meet related specifications and detailing requiments.
Further, pour into ungauged regions self-compacting high-strength concrete in the pre-buried corrugated bushing of armored concrete lower prop, Pre-buried for upper prop high tensile reinforcement is inserted in lower prop corrugated bushing.Described ungauged regions self-compacting high-strength concrete, its strength grade is not Strength grade of concrete less than prefabricated reinforced concrete column.
Further, the steel thimble up and down splicing position outer surface in reinforced column carries out groove welding and realizes connecting, The intensity of weld seam is not less than the intensity of steel thimble.
Further, steel tie is set in the steel thimble of post splicing position, steel tie quality and intensity should meet phase Close specification and detailing requiments.
Described assembled steel reinforced concrete column is fast with the achievable construction speed of the splicing node of post, the recyclable profit of construction material Function.
Compared with prior art, the invention has the beneficial effects as follows:
1st, the present invention realizes reinforced column and post using pre-buried corrugated bushing, pre-buried high tensile reinforcement and styletable steel thimble Connection.The effect of styletable steel thimble is the anti-bending strength that local concrete is strengthened, constrained corrugated bushing and increase post, steel thimble Interior setting steel tie effect is the fastening strength strengthening steel thimble.
2nd, all components are all prefabricated in the factory and complete, and transport to construction site, can assembly connection at the construction field (site), reduce Live assembling reinforcement and formwork work it is ensured that site operation quality, improve building industrialization efficiency of assembling.
3rd, pre-buried for armored concrete upper prop high tensile reinforcement insertion lower prop is filled in the corrugated bushing of mortar by the present invention, to post Steel thimble carries out groove welding, makes armored concrete upper prop and lower prop form common stress after an entirety so as to energy dissipation capacity More superior with ductility, even if it is repaired and replacing cost also can be less after rarely occurred earthquake.
The present invention is further elaborated below in conjunction with the accompanying drawings.
