Currently, the application of precast concrete column type of attachment is up to half-connection formula, in order to meet precast concrete column edge
Protective layer thickness, must be mobile by reinforced column center, which results in reductions of the depth of compressive zone of pillar, influences
The stress performance of pillar, reduces the bearing capacity of pillar, plays unfavorable effect to the whole stress of structure, in order to full
Foot protection thickness degree, while not reducing pillar depth of compressive zone again, pillar section is integrally increased, undoubtedly increases material in this way
Cost causes unnecessary waste.
Utility model content
The purpose of this utility model is to provide a kind of novel precast reinforced concrete column, can guarantee do not change it is prefabricated
In the case where reinforced column protective layer, two half-connection formula precast concrete columns are quickly connected to one by grout sleeve
It rises, to will not be had an impact to pillar depth of compressive zone, the holistic resistant behavior of structure will not be had an impact.
The utility model, which is that the following technical solution is employed, to be realized:
Grouting portion, institute is arranged in the bottom of a kind of novel precast reinforced concrete column, including concrete column, the concrete column
It states grouting portion and concrete column is wholely set and outwardly protrudes a part along concrete column；
It further include the reinforcing bar that several axially penetrate through concrete column, the pre-buried grouting matched with reinforcing bar in the grouting portion
One end of casing, the reinforcing bar is fixedly connected with grouting sleeve；
Slurry outlet is arranged in the top of the grout sleeve, and injected hole, the grouting portion is arranged in the bottom of the grout sleeve
The preformed hole matched with slurry outlet, injected hole is set.
The reinforcing bar is equal to the distance of grouting sleeve to grouting portion edge to the distance at concrete column edge.
The slurry outlet, injected hole are respectively connected with Grouting Pipe.
The stirrup connecting with reinforcing bar is also set up in the concrete column.
Inclined-plane A is arranged in the top in the grouting portion, and the grout sleeve slurry outlet is located at the vertical of at inclined-plane A or grouting portion
At the B of surface.
The beneficial effects of the utility model are:
1, the utility model is quickly linked together two half-connection formula precast concrete columns by grout sleeve, thus
Pillar depth of compressive zone will not be had an impact, the holistic resistant behavior of structure will not be had an impact.
2, the utility model only changes the sectional dimension of bottom of the pillar, does not cause significantly to increase to material,
For the relatively whole method for increasing pillar sectional dimension, material cost is saved, the effect for reducing cost is played.
