Description
Technical field
The utility model relates to road and bridge construction technique field, particularly relates to the connecting structure of a kind of precast pier and cushion cap. Also relate to the installation positioning process of ring section precast pier and cushion cap.
Background technology
At present, the Bridge Pier Construction of Bridges in Our Country substructure adopts cast-in-situ construction method mostly, this kind of constructional method needs road pavement to carry out shutoff when constructing, add that the cast-in-place construction duration is long, construction quality is wayward, and support, template consumption in construction is big, executive cost height, and directly affect the road ability of construction point, incompatible with the requirement of urban construction and development.
The length of bridge is generally more than several kilometers, and even tens kilometers, this just determines bridge and must become across array by a large amount of. For shortening construction period as far as possible, it is ensured that construction quality, reducing the impact on surrounding environment, reduce the impact on traffic, Bridge Pier Construction should adopt in factory for prefabrication prefabricated, the form of construction work that on-the-spot location and installation is connected with cushion cap. Wherein, the connection of precast pier and cushion cap is the key technical problem in design.
The connection of the prefabricated pier body of tradition and cushion cap generally adopts reserved connection reinforcing bar bottom cushion cap top, prefabricated pier body respectively, completes the site welding of reinforcing bar after pier body hoisted in position, and cast connects the method for section concrete. Such mode of connection is too simple to the process of structure, the shearing resistance of junction, antidetonation ability, and steel quantity consumption is relatively big, also seriously affects the durable of agent structure and stress performance, there is potential safety hazard.
For solving above-mentioned deficiency, also there is the trial that some are useful at present, as Chinese patent CN85202839 discloses one " assembled prefabricated components made of reinforced concrete ", add bridge pier bending strength, reduce site operation amount to greatest extent, accelerating construction progress, but the document only discloses the structure of prefabricated component, but do not express the connection relation between prefabricated component and cushion cap.
Chinese patent CN101413250 discloses one " the tenon head type method of attachment of bridge spanning the sea precast pier and cushion cap ", improve the strained condition of connecting portion, solve tradition connect in shearing slip problem, it is to increase the endurance quality of joint. Although but the document disclose between bridge pier with cushion cap a kind of special be connected relation, be also referred between pier body and cushion cap, all need first to locate between each prefabricated pier body and install afterwards, the not location technology in detail assembling construction.
As Chinese patent CN102363946A discloses one " precast assembling upright post supporting platform structure and assembled positioning process thereof ", owing to needing to arrange prestress wire in the through hole of column prefabricated subsection, relative to tradition onsite concrete bridge pier, the cost of the pier column of this method of attachment wants high a lot. In addition, preload tension wire need to carrying out during site operation the operation such as stretch-draw, grouting, construction technology is complicated, and the engineering time is longer.
As Chinese patent CN202543789U discloses one " connecting structure of precast pier and cushion cap ", connecting at the bottom of pier between section end face and pier body bottom surface adopts concavo-convex shearing key to connect, on-the-spot employing dry seam (glueing joint seam) form connects, maximum degree decreases site welding and cast-in-place concrete workload, it is of value to quality control, accelerate construction speed, but the seam between joint section being coincide, it is higher to require, and between joint section, adopting deformed bar or regular reinforcement to connect the bigger construction space of needs, construction technology is complicated. In addition, adopting the dry seam section assembling bridge pier that normal concrete is built, as joint only adopts concavo-convex shearing key, under seismic force effects, bridge pier joint section joint area easily occurs clashing into damage, and the concrete scaling of joint location is serious, and weather resistance has much room for improvement.
Tradition bridge pier generally adopts solid cross section, concrete material large usage quantity, and field cast-in-place construction period is long, Framework Of Steel Reinforcement integral drift easily occurs in construction process, causes concrete cover excessively thin, the problems such as pier stud reinforcing steel bars exposed, corrosion.
Given this, also need at present a kind of can meet the precast pier of multiple object and the connection structures of cushion cap such as supporting capacity is strong, strength of joint height, easy construction are effective, good in economic efficiency simultaneously.
Practical novel content
For solving the problems of the technologies described above, the utility model provides a kind of safe and reliable, and the connecting structure of the precast pier of easy construction and cushion cap, applicable is particularly suitable for ring section in various bridge pier form of fracture, and strength of joint requires high bridge pier.
In order to realize above-mentioned technical purpose, the utility model takes following technical scheme: the connecting structure of a kind of precast pier and cushion cap, include cushion cap, cup mouth installation island and precast pier, location bridge pier is buried at described cushion cap top in advance, described precast pier is by locating pier location, and described precast pier is connected with cushion cap by cup mouth installation island, bottom described precast pier pier body, the section of connection is provided with encased steel plate, WELDING STUDS is welded, and encased steel plate is connected by onsite concrete between island with installing with cup mouth outside described encased steel plate.
Further, described precast pier is annular hollow cross section.
Further, locate by location pier bottom the pier body of described precast pier, and described cushion cap end face locates onsite concrete between precast pier and cup mouth installation island; Described precast pier and cup mouth are installed and are arranged shearing key between island.
Further, described shearing key is arranged on the encased steel plate of the section of connection bottom pier body, is that the WELDING STUDS by welding three layers of staggered arrangement is formed.
Further, described precast pier is arranged in cup mouth installation island.
