Description

Implanted elastic caoutchouc stand apparatus and its for prefabricated concrete bridge pier stud with holding The construction method of platform connection
Technical field
The present invention relates to the implanted interconnection technique and used elasticity of a kind of prefabricated concrete bridge pier stud and cushion cap Attachment means and its connection construction method, particularly a kind of implanted elastic caoutchouc stand apparatus and its for precast concrete bridge The construction method that beam pier stud is connected with cushion cap.
Background technology
The precast assembly technology of bridge pier is to speed up bridge construction and reduces the effective ways of Traffic interruption, meets energy-conservation, ring Protect, the economic construction theory of low-carbon, it will lead the development and application of complete prefabricated bridge structure;Current domestic precast pier with The interconnection technique of cushion cap is mainly using " wet seam " type of attachment of cast-in-place concrete or the type of attachment of " being glued seam ";Both Mode has the following disadvantages:
(1)" wet seam " precast assembly bridge pier of cast-in-place concrete:Although it can reach and the cast-in-place bridge pier phase of monoblock type Same mechanical property, but such precast pier, in the case of geological process, the connecting portion of bridge pier and cushion cap is made in horizontal loading Excessive moment of flexure occurs under, so that there is plastic hinge, serious cracking behaviors, while structure after shake then occurs in concrete Residual deformation it is excessive, this can all cause high maintenance cost, in addition structure because normal operating condition can not be repaired and It is removed.Any of the above factor limits the popularization and application of the assembling technique in earthquake territory of " wet seam ".
(2)The type of attachment of " being glued seam ":Each bridge pier section is typically connected using unbonded prestressing tendon, in plastic hinge Region section is encrypted by stirrup, steel bushing energy-dissipating device or power consumption reinforcing bar, with this come make up merely by presstressed reinforcing steel connect Energy dissipation capacity is low caused by connecing;, can by the way of stirrup encryption under cyclic load but most of results show To obtain preferable ductile performance, but easily cause the Mass Cracking of section concrete;In plastic hinge region using steel bushing power consumption dress Put, preferable ductile performance can be obtained, the residual displacement of structure is smaller, but Structural Energy Dissipation ability is relatively small, and easily makes The cracking of pier stud concrete at into cushion cap;The energy dissipation capacity of structure can be increased using power consumption reinforcing bar, but structure can be increased Residual displacement, bridge pier root crushing of concrete is serious, and thc Ductility Factor of Piers reduces;Due to disappearing to pier stud and cushion cap junction antidetonation The deficiency of energy Study on Measures, limits development and application of the precast pier in Anti-Seismic Region.
The content of the invention
It is an object of the invention to provide a kind of implanted elastic caoutchouc stand apparatus and its for prefabricated concrete bridge pier The construction method that post is connected with cushion cap, the implanted elastic caoutchouc stand apparatus make to form plastic hinge at the big moment of flexure point of structure, increased Add the ductile performance of structure, the power consumption reinforcing bar of implantation makes structure be provided simultaneously with good energy dissipation capacity, there is provided a kind of cushion cap with The connection method of bridge pier " shock-resistant and energy-dissipating ";To solve above mentioned problem existing for prior art.
