Description
Technical field
Bridge expansion joint installation is the utility model is related to, the flexible dress of specifically a kind of double skeleton symbol multi-directional deflection fishbacks
Put.
Background technology
At present, bridge extension joint mainly has modular expansion device（Shaped steel type）With two classes such as fishback retractor device
Type, fishback retractor device have plain edition fishback retractor device and multi-directional deflection fishback retractor device.Bridge is three-dimensional space
Between structure, it has three displacement deformations and the deformation of three corners, that is, shares six to deformation.Fishback retractor device is connection beam body
Important component, only when fishback retractor device also has six to deflection function, bridge structure and fishback can just filled
Put and coordinate common displacement mutually.
National standard《JT/T723-2008》Modular multi-directional deflection comb plate, comb joint bridge extension joint and《TT/T1064-2016》Bridge
Beam damping vibration attenuation multi-directional deflection fishback retractor device is all multi-directional deflection, and some only has two to displacement, it is impossible to meets six to change
The requirement of position, the subject matter present in the junction of the edges of two sheets of paper formula structure of the retractor device are：A, supporting construction is unreasonable, its multi-directional deflection
Mechanism can not expire the requirement such as Plane Rotation and lateral deflection；B, " L " type safety bolt is cast in bridge structure and can not freely coordinated
Displacement, fishback and the mutually coordinated displacement of bridge structure are hindered, so in order to accomplish that fishback retractor device is coordinated with bridge
Displacement, must be requested that fishback retractor device bearing has the bearing of multi-directional deflection function, but also to make insurance（Draw anchor）Spiral shell
Bolt will also have the drawing anchor bolt of multi-directional deflection function, can not also disturb mutually.Junction of the edges of two sheets of paper formula retractor device, it is at bridge seam
The broach of monolithic activity fishback is local freely-supported stress, and it is not to be distributed to stress in one meter of width during stress, so comb
The rigidity of tooth substantially reduces, and broach winding degree but greatly increases, and fatal defects be on bridge floor rubbish incidental directly from broach it
Between space in directly drop into waterstop, influence the Function of waterstop.
The fishback retractor device of prior art can not realize that bridge structure coordinates mutually common displacement with broach panel assembly,
The especially junction of the edges of two sheets of paper formula comb shape bridge extension joint of very large displacement amount, it is monolithic fishback in bridge seam area（Movable fishback）
Broach stress, there is the defects of broach winding degree is big, and rigidity is low, and service life is short, and rubbish is easily directly from broach space
In drop into waterstop, influence the Function of waterstop.
Utility model content
A kind of double freely-supporteds that the purpose of this utility model is in view of the shortcomings of the prior art and designed are prevented falling comb teeth shape bridge
Retractor device, two fishbacks use the supporting construction of the common stress of simply-support, and two pieces of movable fishbacks still have maximum at bridge seam
Tension values length intersects overlap joint, and two broach intersect and with the common stress of simply-support, greatly reduce scratching for broach all the time
Degree, the rigidity of broach are doubled, and rubber type multi-directional deflection bearing group and rubber multi-directional deflection draw anchor group to make its deflection function
Entirely, damping capaicty is strong, and noise is low, and dropproof steel plate thoroughly solves the dust-proof problem of bridge floor of long-standing problem, is especially suitable for city
Elevated bridge and high-grade flexible bridge structure use.
Concrete technical scheme of the present utility model is：A kind of double skeleton symbol multi-directional deflection fishback retractor devices, including A activities
Fishback, B activities fishback and dropproof steel plate and both sides respectively with A beam bodies and the rubber fastening band of B beam body anchor connections,
The mutual socket joint horizontal of two broach of A activities fishback and B activity fishbacks is characterized on dropproof steel plate, and with it is dropproof
Steel plate is to be slidably connected；Described dropproof steel plate one end be arranged on on the stainless steel slide plate of A beam body anchor connections, its other end
It is arranged in B beam bodies, dropproof steel plate is to be slidably connected with stainless steel slide plate；The A activities fishback rearward end be arranged on to
In few two groups multi-directional deflection bearing group, and it is fixed by double limb bolts；The multi-directional deflection bearing group is anchored at A beam bodies
On；The B activities fishback rearward end is to be fixedly connected with dropproof steel plate and B beam bodies by anchor bar；The multi-directional deflection
Bearing group is two resilient support being made up of tetrafluoro plate rubber seat, tetrafluoro slide plate and steel briquetting being arranged on rest pad；Institute
The channel-section steel that rest pad is provided with two chutes for top surface is stated, rest pad is fastened on anchor plate and is welding with anchor plate；The anchoring
Plate is fixedly installed in A beam bodies；Double limb bolts are set two tetrafluoro plate rubber seats, tetrafluoro slide plate and steel briquetting by two chutes
Put on rest pad, and A activity fishbacks are fastened in multi-directional deflection bearing group by anti-return nut.
Two chute is the bar shaped elongated hole along the horizontally-parallel setting of fishback.
The utility model compared with prior art there are two broach to intersect all the time and with the excellent of the common stress of simply-support
Point, the winding degree of broach is greatly reduced, the rigidity of broach is doubled, and enhances security, extends service life, structure letter
Single, easy for construction, damping capaicty is strong, and noise is low, is especially suitable for Bridges on Highway and elevated bridge and speciality Flexible bridge
Use.
