Description
Technical field
The utility model relates to bridge technology fields, and in particular to assembled road and bridge pillarwork.
Background technique
Influence for rapid construction and reduction construction to surrounding enviroment mostly uses now when road and bridge is built
Assembly construction method, common method is: pile foundation and cushion cap cast in situs, and pier stud carries out prefabricated rear lifting and connected with cushion cap
It connects.
It is usually maximum again since the root of pier stud and cushion cap joint are positions most weak in pillarwork, but at this
The position that shearing and moment of flexure occur.After above-mentioned assembled pier stud comes into operation, often there are some problems: on the one hand earthquake when
It waits, the place that pier stud is connect with cushion cap is easy to generate dislocation because of earthquake vibration, and when serious, fracture is collapsed, on the other hand,
The long-term operation of bridge floor, hoisting machinery roll, traction, and being easy to appear pier stud root, nearby slight cracking occurs for concrete, vertical anti-
Press Lack of support；When extent of the destruction weight, under the action of lateral load, the opposite changing of the relative positions easily occurs for pier stud and cushion cap junction
Even it is broken.In the prior art, it is realized in patent CN206635791U and pier stud is subjected to integral preform with upper cushion cap to solve
The problem of certainly previous junction is easy to appear disease, but will lead to the weight of pier stud in this way and be significantly increased, to entire transport and
Hanging device brings burden, or even can not implement.
I.e. when earthquake occurs, portion transmits energy bottom-up, generates horizontal force, easily causes dislocation fracture,
When bridge floor is there are when transverse load, energy transmits from the top down, equally can generate horizontal force in junction, generate dislocation,
Therefore, it between pile foundation and cushion cap, is required to weaken the energy that upper and lower transmitting comes between cushion cap and pier stud.
To sum up, in conjunction with the prior art, design a kind of raising bridge pier column structural soundness, shock resistance pillarwork for
It is of great significance for road and bridge.
Utility model content

The design principle of the utility model are as follows: in order to which the junction for enhancing pier stud and cushion cap is steady in stress or earthquake
Solidity, the application is that pier block is arranged in the lower end position connecting with cushion cap in pier stud, to increase the area of the two contact site,
Groove is set on cushion cap, so that pier block is caught in groove, the boss of cushion cap groove has lateral position-limiting action to pier block,
When occurring to generate transverse load on pier stud, cushion cap can be limited it, prevent transversion malposition, for longitudinal upper pier block
With the connection of cushion cap, be attached using connection reinforcing bar, and connect reinforcing bar and originate in the upper layer of pile foundation, that is, be connected to pile foundation,
Cushion cap and pier stud, so that total globality is stronger, it is more firm；In the junction of pile foundation and cushion cap, the company of cushion cap and pier block
Place's setting energy-consuming device is connect, no matter energy transmits from the top down, still transmits from bottom to top, can pass through secondary energy consumption, significantly
The energy of junction is consumed, influence of the external force to pillarwork is weakened, to guarantee the stability of entire pillarwork and resist
Pinking.
In order to enable mitigating the total weight of pier stud and pier block, the application controls the thickness of pier block, is caught in groove in pier block
Afterwards, the top of the surface distance groove of pier block also maintains a certain distance, in this section space casting concrete layer, thus by pier
Block is embedded in the cushion cap and concrete layer, and it is more steady both to have realized that the weight of pier stud increased few and junction structure in this way
Gu.
The utility model preferred fit formula road and bridge pillarwork, the pier stud and the pier block are integral prefabricated knot
Structure avoids pier stud from connection weak spot position occur.
The utility model preferred fit formula road and bridge pillarwork, the energy-consuming device are viscous damper.
The utility model preferred fit formula road and bridge pillarwork, the edge of the pier block and the edge of the pile foundation exist
It keeps flushing on longitudinal direction, is conducive to connection reinforcing bar in this way and is through to pier block always from pile foundation.
The utility model preferred fit formula road and bridge pillarwork, the quantity in the reinforcing bar duct be it is multiple, be conducive to
Enhance longitudinal connection, enhances stability.
The utility model preferred fit formula road and bridge pillarwork, is arranged cushion block between the cushion cap and the pier block,
It is perfused with cement mortar between the cushion block and the pier block, cushion cap, and connect reinforcing bar collective effect, enhances the steady of pillarwork
Solidity.
The utility model preferred fit formula road and bridge pillarwork, priming petock silt particle between the reinforcing bar duct and reinforcing bar
Slurry, and connect reinforcing bar collective effect, enhances the stability of pillarwork.
The utility model has the following advantages and benefits:
1, the utility model is by being arranged pier block in pier stud lower end, and setting can accommodate the groove of pier block on cushion cap, then in pier
It is laid with concrete on block, and pile foundation, cushion cap, pier block and concrete layer are connected by connection reinforcing bar, to realize road bridge
The rapid construction of beam and stabilized structure double effects.
2, the utility model is equal by the junction in the junction of the pile foundation and the cushion cap, the cushion cap and pier block
Energy-consuming device is set, by secondary energy consumption, consumes the energy of junction significantly, weakens influence of the external force to pillarwork, from
And guarantee the stability and shock resistance of entire pillarwork.
3, the utility model by connection reinforcing bar and reinforcing bar through-hole and pier block and cushion cap between cement injection mortar, into
One step improves the stability of pillarwork.
