Abstract
The invention relates to a steel and concrete combined box-shaped structured pier, which can effectively ensure the construction quality and reduce construction time and construction cost. The steel and concrete combined box-shaped structured pier comprises a reinforced concrete pier body (10) with a box-shaped cross section, and outer side longitudinal reinforcing steel bars (11) arranged in the reinforced concrete pier body (10) at intervals along the peripheral direction of the outer wall of the reinforced concrete pier body (10), and is characterized in that: inner wall steel plates (20) which are closed along the peripheral direction are arranged on the inner wall of the reinforced concrete pier body (10); and reinforcing steel bar anti-shearing instruments (12) which are used for reliably connecting the outer side longitudinal reinforcing steel bars (11) and the inner wall steel plates (20) are longitudinally arranged in the reinforced concrete pier body (10) at intervals. The steel bar anti-shearing instruments (12) in an undulatory manner surround the reinforced concrete pier body (10) on a cross section of the reinforced concrete pier body (10), and its wave peak parts come round and hook the corresponding outer side longitudinal reinforcing steel bars (11) and its trough parts are welded with the inner wall steel plates (20).
Description
Technical field
The present invention relates to bridge pier, particularly a kind of steel-concrete composite box structure bridge pier.
Background technology
Bridge box section bridge pier is the bridge pier form that bridge is commonly used, have that sectional area is little, second moment of area is large, from heavy and light, the rigidity of structure and intensity characteristics preferably, be particularly suitable for using at high pier and high seismic intensity area.But, because the bridge pier inner space is narrow and small, internal mold installation and removal difficulty is large, causing that construction is taken a lot of work, the problem of the aspects such as time-consuming, expense material and quality control difficulty.Along with the application of box section bridge pier is increasingly extensive, must effectively overcome the above problems the duration of guarantee bridge construction, quality and cost.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of steel-concrete composite box structure bridge pier, can effectively guarantee construction quality, reduce engineering time and expense.
The technical solution adopted for the present invention to solve the technical problems is as follows:
Steel-concrete composite box structure bridge pier of the present invention, comprise that cross section is the steel concrete pier shaft of box-shaped, and the outside longitudinal reinforcement of laying along its outer wall hoop interval in the steel concrete pier shaft, it is characterized in that: the inwall of described steel concrete pier shaft is provided with the inwall steel plate of hoop sealing, in the steel concrete pier shaft, longitudinal separation arranges outside longitudinal reinforcement, the reliable reinforcing bar shearing resistance device connected of inwall steel plate, reinforcing bar shearing resistance device on steel concrete pier shaft cross section undulate around steel concrete pier shaft wall body, its crest position is walked around and is hooked corresponding outside longitudinal reinforcement, the trough position with the inwall Plate Welding.
The invention has the beneficial effects as follows, with the inwall steel plate, make inner formword, do not need to remove after the perfusion of steel concrete pier shaft, reduce the pier construction duration, guarantee construction quality; Can reduce pier shaft arrangement of reinforcement number of steel bars and pier shaft wall thickness, therefore can effectively reduce engineering cost simultaneously; Pier shaft intensity, rigidity improve, and have strengthened bridge safty, and have had better anti-seismic performance.
The accompanying drawing explanation
This manual comprises following two width accompanying drawings:
Fig. 1 is the cross-sectional structure schematic diagram of steel-concrete composite box structure bridge pier of the present invention;
Fig. 2 is existing bridge box section bridge pier cross-sectional structure schematic diagram.
Component shown in figure, toponym and corresponding marker number: steel concrete pier shaft 10, outside longitudinal reinforcement 11, reinforcing bar shearing resistance device 12, inboard longitudinal reinforcement 13, inwall steel plate 20.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
With reference to Fig. 1, steel-concrete composite box structure bridge pier of the present invention, comprise that cross section is the steel concrete pier shaft 10 of box-shaped, and at the interior outside longitudinal reinforcement 11 of laying along its outer wall hoop interval of steel concrete pier shaft 10.The inwall of described steel concrete pier shaft 10 is provided with the inwall steel plate 20 of hoop sealing, in the interior longitudinal separation of steel concrete pier shaft 10, arranges outside longitudinal reinforcement 11, the reliable reinforcing bar shearing resistance device 12 connected of inwall steel plate 20.
With reference to Fig. 1, undulate is around steel concrete pier shaft 10 wall bodies on steel concrete pier shaft 10 cross sections for described reinforcing bar shearing resistance device 12, and its crest position is walked around and hooked corresponding outside longitudinal reinforcement 11, and weld with inwall steel plate 20 at the trough position.
Fig. 2 is existing bridge box section bridge pier cross-sectional structure schematic diagram, contrast Fig. 1 and Fig. 2 are not difficult to find, in existing bridge box section bridge pier pier shaft, except laying outside longitudinal reinforcement 11, go back in pier shaft and lay inboard longitudinal reinforcement 13 along its inwall hoop interval, and transverse reinforcement, complex structure.Topmost problem is because the bridge pier inner space is narrow and small, and internal mold installation and removal difficulty is large, causing that construction is taken a lot of work, the problem of the aspects such as time-consuming, expense material and quality control difficulty.And steel-concrete composite box structure bridge pier of the present invention is made inner formword with inwall steel plate 20, after 10 perfusions of steel concrete pier shaft, do not need to remove, reduce construction period, the assurance construction quality of steel concrete pier shaft 10.Because intensity, rigidity after the steel-concrete combination improve, cancel the inboard longitudinal reinforcement of conventional boxes tee section pier pier shaft and reduce pier shaft concrete wall thickness, therefore can effectively reduce engineering cost, can strengthen bridge safty simultaneously, make it to have better anti-seismic performance.
Some principles of the above steel-concrete composite box structure bridge pier of the present invention that just explains through diagrams, be not the present invention to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify likely be utilized and equivalent, all belong to the scope of the claims that the present invention applies for.
