Specific implementation mode

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only explaining this Utility model is not used to limit the utility model.

Embodiment 1

The typically no shockproof structure in traditional expansion joint, when vehicle is by expansion joint, expansion joint generates vibrations, sends out sound Sound.And general expansion joint is two beam-ends that an entirety snaps into bridge, the disadvantage is that, beam-ends needs steel connector, leads Dismounting when causing overall cost high, while being not easy to replace, due to the presence of not no vibration abatement, when expansion joint generates vibrations When bridge can be driven to shake together, the structure to destroy a bridge.And whole expansion joint is also inconvenient to carry in transport, The width for having measured bridge in advance is needed to be customized corresponding expansion joint again when installation.And in practical applications, due to vehicle Roll, the effect to drench with rain of exposing to the weather, the certain positions in expansion joint often will appear some problems and need replacing, however replace when Just it needs entire expansion joint with changing, it is time-consuming and laborious.And the shockproof expansion joint of the utility model, utilize multiple identical widgets I.e. telescopic component is composed the mode of an entirety, is brought conveniently in transport in installation.When some position at expansion joint I.e. frame goes wrong, and only need to save the expense generated when safeguarding, and accelerate by the frame of that section of component with changing Installation progress is truly realized the engineering construction of high-effect high-quality.

Expansion joint as shown in Figure 1 includes two pedestals, 1, two frame 2, multiple elastic elements 3, shockproof plate 4, multiple subtracts Shake gasket 6, multiple fasteners 7.

One end of two pedestals 1 is individually fixed in by pouring in two building element (not shown), and the other end is opposite It is arranged between described two building elements in gap.The cross section of pedestal 1 can take the shape of the letter U, and ensure that after pouring will not be because of pouring It builds insecure and pedestal 1 is made to generate sliding, such as in the present embodiment, protrusion 5 is respectively set in the both ends of pedestal 1, to improve pedestal 1 Structural strength, two protrusions 5 can be integrally formed on pedestal 1.Corrosion resisting steel prepared material may be selected in pedestal 1, in this way can Ensure 1 prolonged use of pedestal.When installation, one end of two pedestals 1 is poured respectively in two building elements, two bottoms The other end of seat 1 is oppositely arranged in gap, and the size in gap is sufficiently large, so that frame 2 can be placed.

Two frames 2 be respectively arranged in two pedestals 1 on the region in the gap.In a particular application, side Frame 2 can be socketed in the protrusion 5 in the gap of pedestal 1, such as the insertion of protrusion 5 in the gap of pedestal 1 In corresponding frame 2.A few elastic element 3 is mounted respectively between each frame 2 and corresponding pedestal 1, in this way, elastic 3 one end of element can be fixed in frame 2, and the other end, which can support in corresponding protrusion 5, (can also be fixed on corresponding protrusion 5 On), spring can be used in elastic element 3.

In the present embodiment, frame 2 is equipped with groove, and the groove of frame 2 is connected by way of socket with respective bump 5 It connects, the inside grooves of frame 2 are equipped with elastic element 3 with raised 5 contact surfaces, and elastic element 3 can be spring, and elasticity is enough Greatly, elastic element 3 can carry out damping when vehicle runs over expansion joint well.

Shockproof plate 4 is fixed on the top of two frames 2, and when being pressurized, and corresponding elasticity is compressed by pushing frame 2 Element 3.Shockproof plate 4, frame 2, elastic element 3 are fixed on pedestal 1 by the utility model successively using multiple fasteners 7.

In the present embodiment, cushioning piece 6 is equipped between shockproof plate 4 and frame 2, cushioning piece 6 can be rubber material Cylindrical spacer.The presence of cushioning piece 6 can reduce vibrations, and can reduce vehicle when driving between shockproof plate 4 and frame 2 Abrasion, reduce road noise.In order to preferably dust-proof, stopper section 8, backstop are extended with towards the gap in the outside of frame 2 Portion 8 can be better protected from bulky grain dust and enter expansion joint, extend the practical time limit at expansion joint.

Shockproof plate 4 may include interlude 41 and two side ends 42 for being located at 41 both ends of interlude.The two of interlude 41 The sliding slot for having and engaging corresponding side end 42 is held, two side ends 42 are fastened in corresponding sliding slot, and can be guided by corresponding sliding slot And opposite interlude 41 slides.In the present embodiment, shockproof plate 4 is three stage structure, and 41 width of interlude can be more than side end 42 Width, two 42 width of side end are equal.It can be set in shockproof plate 4, frame 2 and corresponding protrusion 5 and the multiple of multiple fasteners 7 are installed Mounting hole, mounting hole are in be symmetrically arranged on all parts, as shown in Figure 2.Mounting hole runs through entire frame 2.When installation, fastening Part 7 sequentially passes through shockproof plate 4, cushioning piece 6, frame 2, elastic element 3, pedestal 1, and fastener 7 will by being tightened against on pedestal 1 All parts are fixed.Fastener 7 is fixed and can not move in order to prevent, is only equipped with spiral knot in the lower half portion of fastener 7 Structure ensures that all parts effectively shake.

When this runs over expansion joint, shockproof plate 4 absorbs a part of vibrations, and vibrations continue to conduct, and cushioning piece 6 is eliminated Noise shakes with a part, and vibrations are ultimately conducted on frame 2, is eliminated vibrations by the elastic element 3 inside frame 2, from And reach damping effect, it ensure that the long-time service at bridge and expansion joint.

The present apparatus is suitable to be combined into an entirety by multi-part, and damping device is arranged in some junctions at expansion joint, Actual product can be made to efficiently reduce the vibrations that vehicle generates when driving, the road of various situation complexity can be advantageously applied to Face realizes the maintenance to bridge pavement, can also ensure the safety of participant.Apparent with shockproof effect, installation is simple, fortune It is defeated small, the convenient advantage of management service.
