Description
Technical field
The utility model relates to a kind of construction implement, and especially a kind of shockproof crab-bolt for viaduct pontic, belongs to construction engineering technical field.
Background technology
Along with the quickening of China's infrastructure construction, the constructions that constantly start such as large quantities of highway, bridge, wherein, viaduct is exactly the building body playing important connection function in building operations.Now current when viaduct is built in construction, not only to consider the factor of geographical environment, also will consider local weather condition factor, also will consider load capacity and the factor such as shockproof, therefore have special requirement to the shockproof properties of viaduct.The viaduct now built at present, owing to mostly have employed new-type precast concrete bridge plate structure, this makes the intensity of bridge plate self obtain reinforcement, in this case, bridge plate and bridge plate, and the connection between bridge plate and bridge pier just seems particularly important.Traditional builds in mode, bridge plate adopts the mode of concrete casting to be connected mostly, there is the poor defect of shockproof properties in this structure, require higher to installation accuracy when building, out-of-date easy generation resonance is opened at loaded vehicle, and the opposing of bridge plate self to resonance is more weak, therefore there is certain potential safety hazard.
Summary of the invention
For above-mentioned deficiency of the prior art, main purpose of the present utility model is to solve the problem that existing current viaduct exists anti-seismic performance deficiency, and provides a kind of shockproof crab-bolt for viaduct pontic with better shockproof effect.
The technical solution of the utility model: a kind of shockproof crab-bolt for viaduct pontic, it is characterized in that, comprise the steel sleeve being arranged on bridge seam junction, described steel sleeve is made up of the upper pipe and the lower pipe be embedded in pontic of being located at pontic top, described upper pipe is drum, described lower pipe is inverted cone-shaped structure, and described top tube and down tube are one-body molded; Described lower pipe outer wall is provided with spiral bar, and the cross section of described spiral bar is circular; Be respectively equipped with opening in the top and bottom of steel sleeve, wherein the diameter of steel sleeve lower ending opening is less than the diameter of steel sleeve upper end open, and the opening of steel sleeve upper end is also stamped a steel deck-plate, and described steel deck-plate is disc-shape; In described steel sleeve, be also vertically provided with a shockproof anchor, the bottom of described shockproof anchor is inserted in pontic, and the top of described shockproof anchor is located in pipe, between described shockproof anchor and upper inside pipe wall, form shockproof separate cavities.
Optimally, the protective ring of a circle toroidal is also provided with in the edge, bottom surface of described steel deck-plate.In the utility model, the effect of protective ring is to form protection to the upper end open of steel sleeve, has prevented foreign material or earth from falling in pipe, has ensured with this reliability that crab-bolt is shockproof.
Optimally, to be positioned at the length of pipe equal with 3/4 of upper pipe height for described shockproof anchor.Here require that the height of shockproof anchor can not higher than the height of upper pipe, and when taking the height of 3/4, can realize shockproof optimization, namely best to the isolated effect of vibration, shockproof anchor self can also keep stable and do not rock simultaneously.
Optimally, also scribble one deck anticorrosive coat on the top of described shockproof anchor, described anticorrosive coat is obtained by epoxy novolac coating.By the effect of anticorrosive coat, shockproof anchor non-corrosive can be protected, reach the object in raising whole device application life.
Relative to prior art, the utility model has following beneficial effect:
Shockproof crab-bolt of the present utility model is special and viaduct pontic Aided design, it is by adopting the structure design of hollow, can the vibration wave that transmits of absorption portion pontic, simultaneously can also play effect that is isolated, buffering vibration, enhance the shake-proof ability of pontic.Moreover, shockproof crab-bolt of the present utility model can also strengthen the bonding strength between bridge plate, installs also more for convenience, therefore in building operations, also has good practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of shockproof crab-bolt for viaduct pontic of the utility model.
In figure, 1-steel sleeve, 11-upper pipe, 12-lower pipe, 2-pontic, 3-spiral bar, 4-steel deck-plate, 5-shockproof anchor, 6-shockproof separate cavities, 7-protective ring, 8-anticorrosive coat.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of shockproof crab-bolt for viaduct pontic, comprise the steel sleeve 1 being arranged on bridge seam junction, described steel sleeve 1 is made up of the upper pipe 11 and the lower pipe 12 be embedded in pontic 2 of being located at pontic 2 top, described upper pipe 11 is drum, described lower pipe 12 is inverted cone-shaped structure, described upper pipe 11 and lower pipe 12 one-body molded.Described lower pipe 12 outer wall is provided with spiral bar 3, and the cross section of described spiral bar 3 is circular, and described spiral bar 3 is wrapped on lower pipe 12, strengthens the bonding strength between lower pipe 12 and pontic 2 with this.Be respectively equipped with opening in the top and bottom of steel sleeve 1, wherein the diameter of steel sleeve 1 lower ending opening is less than the diameter of steel sleeve 1 upper end open, and the opening of steel sleeve 1 upper end is also stamped a steel deck-plate 4, and described steel deck-plate 4 is disc-shape; The protective ring 7 of a circle toroidal is also provided with in the edge, bottom surface of described steel deck-plate 4.Here can prevent earth or stone from dropping in steel sleeve 1 by described protective ring 7, form good protected effect.In described steel sleeve 1, be also vertically provided with a shockproof anchor 5, the bottom of described shockproof anchor 5 is inserted in pontic 2, and the top of described shockproof anchor 5 is located in pipe 11, between described shockproof anchor 5 and upper pipe 11 inwall, form shockproof separate cavities 6.In the utility model, the length that described shockproof anchor 5 is positioned at pipe 11 is equal with 3/4 of upper pipe 11 height.Also scribble one deck anticorrosive coat 8 on the top of described shockproof anchor 5, described anticorrosive coat 8 is obtained by epoxy novolac coating.The application life of shockproof anchor 5 can be extended by anticorrosive coat 8.
During work, when pontic there being vibration produce, vibration wave passes to steel sleeve 1 along with one end of pontic 2, at this moment due to the effect of anchor 5 shockproof in steel sleeve 1, vibration wave can be guided to be delivered on shockproof anchor 5, and at this moment shockproof anchor 5 is shaken, and is separated with pontic 2 due to shockproof anchor 5 top, therefore just reach the effect reducing vibration, the vibration being delivered to pontic 2 opposite side obviously reduces.
It should be noted that, above embodiment is only in order to illustrate technical solutions of the utility model but not restriction technologies scheme, although applicant is explained in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those amendments that technical solutions of the utility model are carried out or equivalently to replace, aim and the scope of the technical program can not be departed from, all should be encompassed in the middle of the utility model right.
