Referring to fig. 1 to 12, preferred embodiments of the present invention are shown.
The connecting structure of the prefabricated hollow bridge pier column with the external notch and the sunken bearing platform is not only used for the prefabricated bridge pier column 10 structure, but also can be used for connecting structures of other buildings.
The connection structure of the prefabricated hollow bridge pier stud and the sunken bearing platform of the external notch comprises a prefabricated bridge pier stud 10 and a bearing platform 130; the bearing platform 130 has an upper end surface arranged opposite to the prefabricated bridge pier stud 10, and the upper end surface of the bearing platform 130 is recessed downwards to form a fixing groove 20; the bridge pier 10 comprises an upper supporting section and a lower embedding section, the outer sidewall 100 of the embedding section is inwardly recessed to form a first notch 1401, the first notch 1401 is arranged around the circumference of the prefabricated bridge pier 10, the embedding section is embedded in the fixing groove 20, and the high-strength concrete 150 is poured between the first notch 1401 and the fixing groove 20.
Above-mentioned peripheral hardware notch prefabricated hollow bridge pier stud and sunken cushion cap 130 connection structure that provides, establish fixed slot 20 through digging on cushion cap 130, in prefabricated bridge pier stud 10 and cushion cap 130 connection process, only need hoist prefabricated bridge pier stud 10 to the fixed slot 20 of cushion cap 130 in, pour into high strength concrete 150 again between first notch 1401 and the fixed slot 20, and then realize the zonulae occludens of prefabricated bridge pier stud 10 and cushion cap 130 and effectively strengthen fixed strength, need not weld both, need not fix a position bridge pier stud 10, operations such as measurement, simple to operate, and the junction of prefabricated bridge pier stud 10 and cushion cap 130 is located the inside of cushion cap 130, be difficult for receiving the interference of outside wind-blown water erosion, have stronger shearing, shock resistance.
Moreover, the requirement on the positioning precision of the prefabricated hollow bridge pier stud is low, and the construction is convenient and rapid.
A plurality of upright steel bars 125 are embedded in the fixing groove 20, and the upright steel bars 125 extend upwards and are arranged in an empty manner; when the embedding section is embedded in the fixing groove 20, the pillar reinforcement 125 is placed in the first notch 1401, and the pillar reinforcement 125 can play a role of greatly enhancing the strength of the bridge pier 10 without affecting the installation of the bridge pier 10.
Moreover, a plurality of column reinforcements 125 are embedded in the fixing grooves 20, the column reinforcements 125 and the bearing platform 130 are integrated, and after high-strength concrete is poured, the contact surface between the bearing platform 130 and the bridge pier 10 can be increased, so that the bridge pier 10 and the bearing platform 130 are matched more tightly.
The interior of the prefabricated bridge pier 10 is provided with a cavity 110, and the cavity 110 is communicated with the length direction of the prefabricated bridge pier 10; many reinforcing bars 120 have been preset to the bottom of fixed slot 20, and many reinforcing bars 120 extend up and are the vacant arrangement, and many reinforcing bars 120 wear to establish in cavity 110, have poured into high strength concrete 150 in the cavity 110, like this, realize fixedly from the inside and the outside of prefabricated bridge pier stud 10 respectively to prefabricated bridge pier stud 10, further promote the steadiness that combines between prefabricated bridge pier stud 10 and the cushion cap 130.
The inner diameter of the fixing groove 20 is greater than the outer diameter of the prefabricated bridge pier 10, and in short, it is preferable that the size between the both is the closest, on the one hand, the hoisting of the prefabricated bridge pier 10 is facilitated, and on the other hand, when the prefabricated bridge pier 10 is embedded in the fixing groove 20, the prefabricated bridge pier 10 and the side wall 100 have a gap with the fixing groove 20 and are exposed to the outside, thereby more facilitating the pouring of the high strength concrete 150.
The side walls 141 of the upper portion of the embedment section are inclined upward in a direction away from the cavity 110, which has an advantage in that the side walls 141 of the upper portion of the embedment section allow slurry to more easily flow into the first notch 1401 during the pouring of the high-strength concrete 150, so that the high-strength concrete 150 can more tightly fill the space between the stud reinforcement 125 and the side wall 100 of the prefabricated bridge pier 10, further reducing the filling dead space of the high-strength concrete 150.
Further, the height of the sidewall 141 of the upper portion of the embedment section is lower than the depth of the fixing groove 20, so that the embedment section is completely submerged in the fixing groove 20, and when the concrete 150 is poured into the fixing groove 20, the embedment section has a larger contact area with the concrete 150, and also facilitates the pouring of the concrete 150, and the concrete 150 is not easily overflowed.
Along the direction departing from the cavity 110, the inner side wall 100 of the embedding section is inwards recessed to form a second notch 140, along the height direction of the second notch 140, a plurality of vertically-arranged protruding strips are arranged in the second notch 140, the plurality of protruding strips are arranged at intervals along the circumferential direction of the second notch 140, isolation areas 143 are formed between the side walls of the adjacent protruding strips, the reinforcing steel bars 120 are arranged corresponding to the isolation areas 143, each reinforcing steel bar 120 is arranged in each isolation area 143, and the reinforcing steel bars 120 are arranged in the second notch 140; the isolation area 143 is provided, which can guide and limit each reinforcing steel bar 120, so that the reinforcing steel bars 120 are in a stable state, and the situation of shaking and the like can not occur easily.
And, when the high strength concrete 150 is poured into the cavity 110, the high strength concrete 150 flows into the second notch 140 from top to bottom and is filled between the second notch 140 and the reinforcing steel bar 120, and a common main body is formed between the reinforcing steel bar 120 and the prefabricated bridge pier 10, so that the strength and rigidity of the side wall 100 of the prefabricated bridge pier 10 are enhanced while the prefabricated bridge pier 10 above the bearing platform 130 is fixed, and the shear and seismic resistance of the prefabricated bridge pier 10 is further improved.
Furthermore, a plurality of reinforcing bars 120 are annularly disposed at the edge of the sidewall 100 of the prefabricated bridge pier 10, so that the bearing capacity can be uniformly dispersed, and various stresses borne by the prefabricated bridge pier 10 can be shared together.
