Abstract
The utility model provides a precast reinforced concrete post convenient to assembly, includes precast reinforced concrete post festival section (1), shear connector (2), and the outer fringe is close to all around to precast reinforced concrete post festival section (1) regional setting has many cableways (5), and the central zone of precast reinforced concrete post festival section (1) up end is equipped with lug (1 -2), the lower part of shear connector (2) embedding is on the upper portion of precast reinforced concrete post festival section (1), and the quantity of shear connector (2) be four, four (2) two double -phase settings in lug (1 -2's) periphery of shear connector symmetrically, the central zone of the lower terminal surface of precast reinforced concrete post festival section (1) be equipped with and the concave part (1 -1) of lug (1 -2) looks adaptation, concave part (1 -1) all around with four shear connector (2) corresponding positions be equipped with with pore (3) of four shear connector (2) looks adaptations. This concrete column loads and unloads with the transportation convenience, can shows the reduction of erection time, improves the efficiency of construction.
Description
Technical field
The utility model belongs to technical field of bridge engineering, is specifically related to a kind of prefabricated reinforced concrete column being convenient to assemble.
Background technology
In today of urban construction fast development, more low-carbon (LC), environmental protection, efficiently construction requirements are proposed to building operations in city.Original building operations mode little by little replace by industrialization of construction industry Construction Mode.Assembled architecture more and more obtains the support of government and widelys popularize.Assembled architecture is exactly the component such as beam, post, body of wall of prefabricated reinforced concrete in factory in advance, and the scene that is then transported to carries out assembledly becoming building.
Some prefabricated reinforced concrete column sections upper and lower end faces when prefabricated mostly are plane section now, and the reinforcing steel bars exposed in pillar sections goes out cross section certain length.This prefabricated post minor segment is owing to leaving reinforcing bar in upper and lower end face, and after being transported to scene, upper-lower segment adopts cast-in-place wet joint to carry out assembled connection.This kind of pillar sections has following several drawback: one is that handling and transport are inconvenient, and the reinforcing bar exposed easily is hurted sb.'s feelings, and is inconvenient to carry, and workman easily touches bar bending when carrying; Two is that efficiency of construction is not high, and cast in situs wet joint connects, and needs artificial formwork, maintenance, form removal etc., has both consumed manpower, and taken again the duration; Three be stitching portion concrete appearance unsightly, cast-in-place wet joint and prefabricated subsection joining place easily produce step and connect a batch vestige, affect pillar overall appearance.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of prefabricated reinforced concrete column being convenient to assemble, the handling of this concrete column and convenient transportation, energy significantly reduction of erection time, raising efficiency of construction, and be not easy step in splicing and connect a batch vestige.
To achieve these goals, the utility model provides a kind of prefabricated reinforced concrete column being convenient to assemble, comprise prefabricated reinforced concrete column sections, shear connector, prefabricated reinforced concrete column sections surrounding is provided with many handling reinforcements near the region of outer rim, the central area in prefabricated reinforced concrete column segments upper side face is provided with projection, the bottom of described shear connector is embedded in the top of prefabricated reinforced concrete column sections, the quantity of shear connector is four, four shear connectors are arranged on the periphery of projection between two relatively symmetrically, the central area of the lower surface of prefabricated reinforced concrete column sections is provided with the recess suitable with described projection, the surrounding of the recess position corresponding with four shear connectors is provided with the duct suitable with four shear connectors.
The longitudinal direction of prefabricated reinforced concrete column sections is provided with equably and organizes stirrup more, within stirrup is arranged on the surface of prefabricated reinforced concrete column sections.
The shape of described shear connector is L-type.The bottom of L-type can be preset in the top of prefabricated reinforced concrete column sections 1 like this, contribute to the intensity that shear connector improves anti-shearing force.
The length of described shear connector beyond prefabricated reinforced concrete column segments upper side face is 500-1000mm.This length range is not only convenient to assemble, and is easy to processing.
This reinforced concrete post sections is convenient to carry out site assembly, can first prefabricated in factory after be transported to scene and carry out assembled, during on-site consolidation, first the prefabricated reinforced concrete column sections of downside is fixed, then the prefabricated reinforced concrete column sections on the upside of being sling by hanging device, the prefabricated reinforced concrete column sections of itself and downside is aligned, guarantee that the exposed junction of shear connector aims at duct, then the prefabricated reinforced concrete column sections of upside is slowly fallen, until upper and lower prefabricated post sections tight connecting, this assembling mode eliminates cast link, effectively can shorten construction period, significantly improve efficiency of construction.
