Description
Technical field
The invention belongs to prefabricated concrete structure technical field, it is related to a kind of precast concrete column and is connect with column assembled
Node.
Background technique
Prefabrication is that one kind is prefabricated in the factory building element, and transport is to scene after maintenance and acceptance(check)
The construction method that installation is completed.Develop prefabrication and is conducive to the economize on resources energy, reduction construction pollution, promotion
Labor productivity and construction quality promote construction industry to realize information-based, industrialization, are to promote supply side structural reform, change
Solve the important measure of superfluous production capacity and novel Urbanization Progress.
In building structure, column is structure member vertical in building, and support column upper load is simultaneously transferred to basis.?
In prefabricated concrete structure, the connection between column and column mainly uses grout sleeve interconnection technique, buries in precast concrete column
Grout sleeve, injection grouting material completes the connection between upper and lower segmented column to component on-site hoisting afterwards in place.But in practical applications,
There are shortcomings for grout sleeve interconnection technique, first is that sleeve and steel reinforcement abutting joints difficulty are big when construction；Second is that sleeve grouting is closely knit
Detection difficult is spent, spillage is easy to appear and presss from both sides empty phenomenon, construction quality is difficult to ensure；Third is that sleeve process is complicated, cost is high,
So that assembly concrete building overall cost improves.Patent CN105239723A, which is disclosed, a kind of to be connected using steel node
Precast concrete column, connection upper and lower side weld after agreeing with, and avoid wet construction, but the node construction speed is slow, site welding matter
Amount is difficult to ensure；Patent CN207469439U discloses a kind of precast concrete column connected node, which simplifies node area steel
The overlap joint work of muscle pours operation after reducing node area, but junction Grouted density is difficult to ensure, is easily gone out in work progress
Now press from both sides dead level.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of simple structure, power transmission is reliable, construction is simple
Single, good economy performance, quality of connection precast concrete column easy to detect and column assembled connecting node.
Technical solution of the present invention: above saving the pre-buried conversion fashioned iron in precast concrete column bottom, and lower section precast concrete capital is pre-
Conversion fashioned iron is buried, upper and lower two sections precast concrete column conversion fashioned iron is connected by high-strength bolt, is surrounded by coagulation on the outside of conversion fashioned iron
Soil.
Preferably, fashioned iron is pre-buried is disposed with shear key in concrete shell of column for conversion.
Preferably, fashioned iron height is converted as h, and length a=200~300mm of revealed section anchors into the length of concrete shell of column
Spend b=2.5h~3.0h.
Beneficial effects of the present invention: it is connected using conversion fashioned iron with high-strength bolt between upper and lower section precast concrete column, structure
It makes simply, power transmission is reliable；Quality of connection facilitates inspection, and final product quality is controllable；Construction and installation are quick, high-efficient, meet assembled
The requirement of building.

Specific embodiment
The present invention will be further described with reference to the accompanying drawing and by embodiment.
Embodiment 1
A kind of precast concrete column and column assembled connecting node, including upper section precast concrete column 1, lower section concrete
Earth pillar 2 converts fashioned iron 3, shear key 4, high-strength bolt 5.The upper pre-buried conversion fashioned iron 3 in 1 bottom end of section precast concrete column converts fashioned iron
3 height are h, and exposed segment length is a, and the length for anchoring into concrete shell of column is b, and is disposed with shear key 4；Lower part precast concrete
The pre-buried conversion fashioned iron 3 in 2 top of column converts 3 height of fashioned iron as h, and exposed segment length is a, and the length for anchoring into concrete shell of column is b,
And it is disposed with shear key 4；The conversion fashioned iron 3 of precast concrete column 1,2 is connected by high-strength bolt 5, is converted and is surrounded by the outside of fashioned iron 3
Concrete.
Embodiment 2
Unlike the first embodiment: the conversion connectionless end plate of fashioned iron 3, between the conversion fashioned iron 3 of precast concrete column 1,2
It is connected using bolt 5.
Embodiment 3
Unlike the first embodiment: the conversion connectionless end plate of fashioned iron 3 is converted and is connected between fashioned iron 3 using weld seam 6.
