Description
Technical field
The invention belongs to technical field of civil engineering, and in particular to arrive a kind of precast segment assembly bridge pier steel member and construction
Methods and applications.
Background technique
Conventional bridge construction is to carry out live formwork casting concrete in boundary of works area block place, this will seriously affect
Original traffic, while mechanical construction noise is larger to the interference of surrounding enviroment greatly, and the assembled bridge pier in part is in use process
In there is also the problems of stitching portion durability deficiency.The research and development and application of New Style Concrete Materials such as super ultra-high performance concrete,
Bridge construction technique is promoted to change a lot, the superstructure of bridge has been carried out section assemblingization construction, and part is spelled
Filling bridge pier, there is also the problems of stitching portion durability deficiency in use.For over strait, river bridge, the quantity of bridge pier is more
Size is big and the severe corrosive of marine environment causes the turnover reuse rate of steel form relatively low；For Urban Bridge,
Since by people, vehicle flowrate is bigger and the place of construction is smaller etc., and factors are influenced, it is unfavorable for applying for modern mechanical
Work.Therefore a kind of construction method of precast segment assembly bridge pier is needed, size is larger, the live bridge pier for being not easy to construction is in work
Factory carry out precast segment, be transported to scene be accurately positioned after with ultra-high performance concrete carry out each prefabricated subsection between connection.
Summary of the invention
In view of the above deficiencies, the present invention provides a kind of precast segment assembly bridge pier steel member and construction method and application, with

Template and support superstructure, anchoring temporarily and the working security for increasing assembled bridge pier are served as, it can also be after the completion of construction
It removes and reuses, increase the utilization rate of steel, the construction behaviour of the final prefabricated and live quick-assembling of batch production for realizing bridge pier
Make.The construction method uses the factorial production, both can guarantee the construction quality of bridge pier, has reduced site operation amount, can also be into one
Step accelerates the batch production construction speed of bridge.
To achieve the above object, the technical solution adopted by the present invention to solve the technical problems is: it is pre- to provide a kind of segment
Make assembled bridge pier steel member, including short steel member, long Steel section member and anchor and position reinforcing bar.Short steel member and long fashioned iron structure
Part is semicircle, and several ribbed stiffeners one are provided on short steel member, and short steel member both ends junction is provided with several perpendicular
Several horizontal bolt holes one are provided with to bolt hole one, and on the steel plate of lower end；Several ribbed stiffeners two are provided on long Steel section member,
Long Steel section member both ends junction is provided with several vertical bolts hole two, and several horizontal bolt holes are provided on the steel plate of lower end
Two；Anchor and position reinforcing bar is arranged in steel reinforcement cage in evenly dispersed shape, and anchor and position reinforcing bar outer end is provided with thread, and inside
It is provided with several reinforced steels to match.
Further, the anchoring that interspersed anchor and position reinforcing bar is separately provided on short steel member and long Steel section member is fixed
Position reinforced hole one and anchor and position reinforced hole two.
Further, horizontal bolt hole one is identical with two size of horizontal bolt hole.
The construction method of bridge pier is carried out using above-mentioned precast segment assembly bridge pier steel member, comprising the following steps:
(1) anchor and position reinforcing bar and steel reinforcement cage are bound, and remain for the connection reinforcing bar of connecting bridge pier segment in advance at both ends,
Then it casting concrete and is conserved；
(2) two pieces of short steel members are spliced in segment bridge pier lower end after the completion of step (1) conserves, in segment bridge pier upper end
Connect two pieces of long Steel section members, and form rim of a cup, at the same by fixing bolt by short steel member and long Steel section member respectively with
The connection of anchor and position reinforcing bar；
(3) ultra-high performance concrete is filled in the rim of a cup of step (2) and is vibrated, then assembled bridge pier segment, connects steel
Muscle is evenly distributed on stitching portion, then connects short steel member and long Steel section member by high-strength bolt, to ultra-high performance concrete
After hardening, short steel member and long Steel section member are removed, completes precast segment assembly Bridge Pier Construction.
Further, two pieces of short steel members are connected on vertical bolt hole one by high-strength bolt, two pieces of long Steel section members
It is connected on vertical bolt hole two by high-strength bolt.
Further, long Steel section member is embedded into cushion cap, realizes the connection of cushion cap and segment bridge pier.
Further, short steel member is embedded into bent cap, realizes the connection of bent cap and segment bridge pier.
Further, steel hoop construction can be used in short steel member and long Steel section member.
Above-mentioned precast segment assembly bridge pier steel member is applied in round pier, rectangle pier, polygon pier and nose circle rectangular hollow
Application in terms of work.
In conclusion the invention has the following advantages that
1, the anchor and position reinforcing bar reserved when segment bridge pier is prefabricated can guarantee Steel section member and the intersegmental connection of bridge pier,
The Steel section member of each component ends both with anchoring temporarily and can undertake the gravity of member upper, can also play the role of template.
Each segment bridge pier component for being prefabricated in the factory is simultaneously reserved due to overlapped at scene reinforcing bar, be accurately positioned it is assembled after carried out with concrete
Connection.Due to junction indulge muscle doubles and ultra-high performance concrete can effective anchor bar, make assembled bridge pier can be with
Reach the mechanical characteristic of identical size bridge pier integral cast-in-situ.
2, Steel section member reuses the consumption for reducing steel, can reduce the overall cost of bridge construction；Steel section member was both
It can support superstructure that can also play the role of anchoring temporarily, guarantee the safety of segment bridge pier assembling construction.
3, segment pier stud can be prefabricated in the factory, it is ensured that the construction quality of engineering, the assembly between each component are high-efficient；Respectively
Prefabricated components end is reserved with overlap joint reinforcing bar, can directly carry out assembling construction at the scene, and construction efficiency is high.
4, occupied ground space is small, and only cushion cap is that pouring construction, pier shaft and bent cap are all being prefabricated in the factory at the scene, therefore
Without setting up the template for pouring pier shaft and bent cap, the area of construction site is reduced.
5, power choring is constructed.For larger-size bridge pier, can be reduced by increasing the number of prefabricated subsection
The weight of each segment reduces the constructing operation of big machinery.
6, interfered by construction environment it is small, it is applied widely, shorten the construction period.The prefabricated work of each component is all completed in factory
, it is not influenced by construction environment；Next step constructing operation can be carried out after the completion of the concreting of wet seam section, it is no longer necessary to
Template is set up, the construction speed of bridge is accelerated.
