Abstract
The utility model relates to the technical field of bridge construction and particularly relates to an expansion joint structure. A hidden type bridge expansion joint structure comprises a main beam, a bridge abutment and a butt strap, wherein the main beam is supported by the bridge abutment through a bridge deck slab or a cast-in-place layer on the main beam in a spanning manner; the right side of the butt strap is connected with a roadbed; the hidden type bridge expansion joint structure further comprises an elastic stretching body; the elastic stretching body is placed on the back wall of the bridge abutment; the left side of the elastic stretching body is connected with the main beam. Due to the technical scheme, a bridge deck expansion joint device between a beam end and the bridge abutment is canceled, and the hidden type bridge expansion joint structure is a novel structure which can meet expansion deformation of a bridge; bridge bumps and vehicle impact are alleviated; the main body structure is definite in stress; design construction is convenient, maintenance and replacement are reduced, the construction maintenance cost is lowered, and the service life of the bridge structure is prolonged; the hidden type bridge expansion joint structure is suitable for a new built bridge structure and also particularly suitable for improvement on expansion joints on the bridge abutment of an old bridge and novel connection of small and medium-sized bridges and has a large application range.
Description
Technical field
The utility model relates to bridge construction technical field, is specifically related to a kind of expansion joint structure.
Background technology
Bridge construction, for the needs of adaptive deformation, generally all can arrange a point gap between beam body two ends, beam-ends and abutment, is called again shrinkage joint, in order to make driving steadily, stretching device is set between shrinkage joint; After stretching device, the attachment strap of operated by rotary motion 5m～8m; Attachment strap is shelved on abutment parados or bracket, keeps separating with girder.Expansion gap device is due to the impact that stopped up by vehicle driving impact, wearing and tearing and foreign material, and well damage, needs often change and safeguard.
Some small bridges can be sewed on steel plate is set with separating of abutment at beam-ends, elastic telescopic body is set on steel plate, and elastic telescopic body one end is arranged on girder, and one end is arranged on abutment parados, replace expansion gap device with elastic telescopic body, complete the dilatation of bridge.This set can play cancels outseam, the more effect of steady and smooth that makes to drive a vehicle, but because steel plate is under vehicle and the effect of beam body deformability, translation and rotation still can occur, and can affect result of use and the physical life of elastic telescopic body.
Utility model content
The purpose of this utility model is, a kind of implicit expression bridge expanssion joint structure is provided, and solves above technical problem.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of implicit expression bridge expanssion joint structure, comprise girder, abutment and attachment strap, described girder is supported on abutment across seam by its bridge deck or the in-situ layer on it, the right side of described attachment strap connects roadbed, it is characterized in that, also comprise an elastic telescopic body, described elastic telescopic body is held on abutment parados, and the left side of described elastic telescopic body connects described girder.
The right side of described elastic telescopic body connects attachment strap, asphalt concrete pavement on described girder, described elastic telescopic body, described attachment strap and described roadbed.
The right side of described elastic telescopic body connects cement concrete pavement, and described cement concrete pavement is arranged on described attachment strap and described roadbed, and the left frame of described attachment strap is located on the right side bracket of described abutment.
The utility model solves the problem of driving by the bridge deck or the in-situ layer that extend on girder, adapt to the distortion of bridge by the compression of elastic telescopic body and elongation strain, because elastic telescopic body deformability and girder, attachment strap or cement concrete pavement bond well on contact surface, together compatible deformation, thus realize seamless surface structure.This structure saves expansion gap device and repeatedly changes and maintenance cost, can water proof and dust proof, and reduce vehicular impact and jump car, improve structure application life, improve the comfortableness of Vehicle Driving Cycle.
The longitudinal length of described elastic telescopic body is 2cm～150cm.
Beneficial effect: owing to adopting technique scheme, the utility model has been cancelled deck expansion joint device between beam-ends and abutment, but can meet again the novel structure of bridge dilatation, reduce bumping at bridge-head and vehicular impact, agent structure is stressed clear and definite, design and construction are convenient, reduce and safeguard replacing, reduce construction and maintain cost, improve bridge construction application life, not only be applicable to newly building bridge structure, be also particularly suitable for the novel connection of the transformation of old bridge Abutment shrinkage joint and small bridge, applied widely.
Accompanying drawing explanation
Fig. 1 is the implicit expression bridge expanssion joint structure of asphalt concrete pavement of the present utility model;
Fig. 2 is the implicit expression bridge expanssion joint structure of cement concrete pavement of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with further elaboration the utility model of concrete diagram.
With reference to Fig. 1, Fig. 2, an implicit expression bridge expanssion joint structure, comprises girder 1, abutment 2 and attachment strap 3, and girder 1 is supported on abutment 2 across seam by its bridge deck or the in-situ layer on it, the right side of attachment strap 3 connects roadbed 6, also comprises that a longitudinal length is the elastic telescopic body 4 of 2cm～150cm.Elastic telescopic body 4 is held on abutment 2 parados, and the left side of elastic telescopic body 4 connects girder 1.
The utility model solves the problem of driving by the bridge deck or the in-situ layer that extend on girder, adapt to the distortion of bridge by the compression of elastic telescopic body and elongation strain, because elastic telescopic body deformability and girder, attachment strap or rigid pavement bond well on contact surface, together compatible deformation, thus realize seamless surface structure.This structure saves expansion gap device and repeatedly changes and maintenance cost, can water proof and dust proof, and reduce vehicular impact and jump car, improve structure application life, improve the comfortableness of Vehicle Driving Cycle.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
