Description
Technical field
The utility model belongs to building field, more particularly to a kind of precast pier structure.
Background technology
Bridge pier structure generally includes cushion cap and column, and former way is typically that the mode of cast in situs builds bridge pier, but
It is so to have construction-time long, delays traffic, the shortcomings of work progress is easily influenceed by weather and noise disturbs residents in work progress.
Therefore people are gradually built using prefabricated bridge pier component.A kind of such as disclosed in patent 201420741735.5 bridge pier,
Bridge pier can be formed by simply being set up by bearing hole on prefabricated tubular pile, precast pier and precast pier.But in actually building,
Prefabricated tubular pile and precast pier are the rigid structures that concrete is built up, so gap is had between bearing hole and prefabricated tubular pile,
So as to cause bridge pier unstable.If filling concrete into gap, it can only add from up to down, it is easy to by gap bottom
Air is blocked so that bottom produces space, causes bridge pier not enough to consolidate.In addition do not have between said structure pile tube and precast pier
Reinforcing bar fixed connection structure, causes its anti-shear ability not enough, and connection is not enough consolidated.Finally, existing column is one-piece casting
Form, make, use and transport inconvenience.
Utility model content
To solve the above problems, the utility model provides a kind of precast pier structure.The utility model can prevent pre-
Occur bubble when being sealed between cushion cap and prefabricated stand column processed and cause unbalanced, and add the steadiness of precast pier and anti-shearing
Performance, and there is provided a kind of prefabricated stand column be easy to assemble and transported.
To reach above-mentioned technique effect, the technical solution of the utility model is：
Being provided with the top of a kind of precast pier structure, including prefabricated cushion cap and prefabricated stand column, prefabricated cushion cap is used to install prefabricated
The mounting hole of column, trapezoidal positioning convex is in the convex longitudinal section that is formed with the mounting hole bottom；Prefabricated stand column bottom
There is the positioning hole coordinated with positioning convex, the height of positioning convex is more than the height of positioning hole；Opened up at the top of the prefabricated cushion cap
There is the injected hole for Pumping concrete, injected hole is connected with the bottom of mounting hole by intercommunicating pore；Prefabricated stand column bottom is fixed
Have and the second U-shaped reinforcing bar is fixed with the first U-shaped reinforcing bar, prefabricated cushion cap；First U-shaped reinforcing bar and the second U-shaped reinforcing bar are in mounting hole
Provided with overlay segment；Prefabricated stand column bottom surrounding is formed with chamfering；The bottom of prefabricated stand column is formed with annular projection and annular recess.
Further to improve, the prefabricated stand column includes some short columns and the foundation being connected with prefabricated cushion cap；The short column
Through hole between the through hole and short column and foundation that are provided between some through holes, short column is corresponded, inserted with reinforcing bar in through hole
And it is perfused with concrete.
Further to improve, the positioning convex is circular cone shape.
Further to improve, the section of the annular projection is arc.
Further to improve, the section of the annular recess is arc.
Brief description of the drawings
Fig. 1 is assembly structure diagram of the present utility model；
Fig. 2 is the overlooking the structure diagram of short column.
Embodiment
The technical solution of the utility model is illustrated below by way of embodiment and with reference to accompanying drawing.
Embodiment 1
A kind of precast pier structure as shown in Figure 1, including prefabricated cushion cap 1 and prefabricated stand column 2, the prefabricated top of cushion cap 1 are set
There is the mounting hole 3 for installing prefabricated stand column 2, trapezoidal positioning convex is in the convex longitudinal section that is formed with the bottom of mounting hole 3
4；The bottom of prefabricated stand column 2 has the positioning hole 5 coordinated with positioning convex 4, and the height of positioning convex 4 is more than the height of positioning hole 5
Degree；The top of prefabricated cushion cap 1 offers the injected hole 6 for Pumping concrete, and the bottom of injected hole 6 and mounting hole 3 passes through
Intercommunicating pore 7 is connected；The bottom of prefabricated stand column 2 is fixed with the first U-shaped reinforcing bar 8, prefabricated cushion cap 1 and is fixed with the second U-shaped reinforcing bar 9；The
One U-shaped reinforcing bar 8 and the second U-shaped reinforcing bar 9 are provided with overlay segment 10 in mounting hole 3；The bottom surrounding of prefabricated stand column 2 is formed with chamfering
11；The bottom of prefabricated stand column 2 is formed with annular projection 12 and annular recess 13.Positioning convex 4 is preferably circular cone shape, or
Wedge shape.The section of annular projection 12 and annular recess 13 is preferably arc.
The utility model inserts prefabricated stand column 2 on the positioning convex 4 of mounting hole 3, then injects coagulation by injected hole 6
Soil, the space between filling prefabricated stand column 2 and prefabricated cushion cap 1.Because concrete is gradually filled from bottom to top in mounting hole 3,
Therefore it can say that air is fully driven away, without sealing air in gap.Connect to increase prefabricated stand column 2 with prefabricated cushion cap 1
The tight type and anti-shearing shape connect, there is provided the first U-shaped reinforcing bar 8 and the second U-shaped reinforcing bar 9.Annular projection 12 and annular recess 13
The stroke up and down of prefabricated stand column 2 is limited, good against shock effect can be played.
As shown in Fig. 2 making transport for convenience, prefabricated stand column 2 includes some short columns 14 and is connected with prefabricated cushion cap 1
Foundation 15；Short column 14 is provided with the through hole 16 between the through hole 16 between some through holes 16, short column 14 and short column 14 and foundation 15
Correspond, inserted with reinforcing bar 17 and be perfused with concrete 18 in through hole 16.Short column 14 and foundation 15 are first so transported into building site,
Then by its through hole to it, reinforcing bar 17 is inserted into, concrete perfusion 18 is sealed, that is, prefabricated stand column 2 is made, it is processed need not
Oversized making apparatus, and transport is quick, assembling is flexible.
Above are only one of the present utility model it is specific be oriented to embodiment, but design concept of the present utility model not office
It is limited to this, all changes for carrying out unsubstantiality to the utility model using this design all should belong to infringement guarantor of the present utility model
Protect the behavior of scope.
