Embodiment
For the ease of understanding the present invention, the present invention is made below in conjunction with Figure of description and preferred embodiment more complete
Face, careful description, but protection scope of the present invention is not limited to embodiment in detail below.
Unless otherwise defined, the implication that all technical terms used hereinafter are generally understood that with those skilled in the art
It is identical.Technical term used herein is intended merely to describe the purpose of specific embodiment, is not intended to the limitation present invention
Protection domain.
The ultra-high performance concrete post component of this assembled architecture disclosed in the present embodiment, by more very-high performance coagulations
Earth pillar is mutually spliced, mainly as the pillar of steel reinforced concrete assembling building.The present embodiment selects two very-high performances
Concrete column splices, and other embodiments can be selected according to the height of building using two or more root ultra-high performance concrete posts
It is spliced into single piece.For the ease of description, " ultra-high performance concrete post " is referred to as " concrete column " by herein below.
As shown in figure 1, this concrete column component is spliced by downside concrete column 1 and upside concrete column 2.
Prefabricated cylinder 11 under downside concrete column 1 includes is can be seen that with reference to Fig. 2 and Fig. 6 and is embedded in the steel of its end in advance
Column cap GZT, under the end face of prefabricated cylinder 11 have the tenon 111 stretched out in outside steel column head GZT
Can be seen that upside concrete column 2 with reference to Fig. 3 and Fig. 7 includes upper prefabricated cylinder 21 and is embedded in the steel of its end in advance
There is shape groove 211 corresponding with tenon 111 column cap GZT, the end face of upper prefabricated cylinder 21.
Steel column head GZT is can be seen that with reference to Fig. 1 to Fig. 7 to be welded by end plate GZT1 and side plate GZT2.The present embodiment
Upper prefabricated cylinder 21 shape of cross section of prefabricated cylinder 11 with is rectangle, steel column head GZT shape and the shape of prefabricated cylinder
