Detailed description of the invention:
Below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiments are for illustration of the utility model and unrestricted scope of the present utility model.The implementation condition adopted in embodiment can do further adjustment according to the condition of Specific construction unit, and not marked implementation condition is generally the condition in normal experiment.
Specific embodiment mode:
Embodiment one: overall bridge
Fig. 1 ~ Fig. 3 shows first specific embodiment that this chain type attachment strap based on seamless bridge of the utility model constructs, this is configured to overall bridge, it comprises abutment 6, girder 11, bridge deck 10 and attachment strap 3, and wherein abutment 6, girder 11 and bridge deck 10 form the main bridge section of bridge.
Key improvements of the present utility model is: the quantity of described attachment strap 3 is more than two pieces, and these attachment straps 3 are arranged in the end of described main bridge section and the length direction along described main bridge section is arranged in juxtaposition.Described main bridge section (being specially the abutment 6 of main bridge section) and near this main bridge section that block attachment strap 3 between and arbitrary neighborhood two blocks of attachment straps 3 between be provided with expansion joint (E.J.) 4.And be all connected by dumbbell shape structure reinforcing bars 1 between described main bridge section with that block attachment strap 3 near this main bridge section and between two blocks of attachment straps 3 of arbitrary neighborhood.Described dumbbell shape structure reinforcing bars 1 is made up of straight line muscle 1a and two the annular muscle 1b being connected to these straight line muscle two ends, and this dumbbell shape structure reinforcing bars 1 can utilize bender quick Fabrication.For connecting the dumbbell shape structure reinforcing bars 1 of main bridge section and attachment strap 3, two annular muscle 1b is separately fixed at main bridge section and attachment strap 3 is inner; And for connecting the dumbbell shape structure reinforcing bars 1 of adjacent two pieces of baffle plates 3, it is inner that two annular muscle 1b is separately fixed at two blocks of attachment straps 3.
Under the connection function of dumbbell shape structure reinforcing bars 1, described girder 11, bridge deck 10, abutment 6 and attachment strap 3 form an overall structure, and this structure shows as the performance of seamless bridge under force.
As shown in Figure 3, this example is enclosed with rubber sleeve 2 on described dumbbell shape structure reinforcing bars 1, thus ensure, when day and night temperature and temperature in four seasons change, to be adapted to the displacement of girder by the distortion being embedded in the rubber sleeve 2 on the dumbbell shape structure reinforcing bars in concrete.During roadbed generation sedimentation, be out of shape and adapted to by the dumbbell shape structure reinforcing bars 1 of expansion joint (E.J.) 4, avoid attachment strap 3 top and occur transverse crack, ensure that attachment strap 3 durability.The dumbbell shape structure reinforcing bars 1 of main bridge section and attachment strap 3 junction and attachment strap 3 and attachment strap 3 junction has multiple, annular muscle 1b on these dumbbell shape structure reinforcing bars 1 can vertically arrange, also can horizontal arrangement, mean level and the distribution interlaced with each other of vertical dumbbell shape structure reinforcing bars 1, as Fig. 2.
First the length travel of bridge is out of shape absorption portion displacement at first expansion joint (E.J.) place by the rubber sleeve be wrapped on dumbbell shape structure reinforcing bars, then displacement is passed to second expansion joint (E.J.) place, by the rubber sleeve absorption portion distortion on second expansion joint (E.J.) place dumbbell shape structure reinforcing bars, by that analogy, last block attachment strap end and roadbed joining place do not have length travel.
Refer again to shown in Fig. 3, described rubber sleeve 2 is only wrapped on a straight line muscle 1a and annular muscle 1b of described dumbbell shape structure reinforcing bars 1.Namely only one end of dumbbell shape structure reinforcing bars 1 is provided with described rubber sleeve 2.
This example is being filled with polyurethane material 7 in described expansion joint (E.J.) 4.
Also be provided with sleeper beam 8, the end of described attachment strap 3 is supported on described sleeper beam 8, to ensure the structural stability of attachment strap 3.
In addition, this example is equipped with felt bed course 9 and thin sand 5 below described attachment strap 3.The existence of asphaltic felt bed course 9 and thin sand 5, decreases the frictional resistance under attachment strap 3, thus two second inner force that reduction bridge construction causes under temperature action, ensure that the power transmission between attachment strap 3 simultaneously.Wherein, asphaltic felt bed course 9 is placed on abutment and sleeper beam, and support attachment strap two ends, thin sand is embankment top layer, directly supports attachment strap.
As Fig. 1, this routine this chain type attachment strap structure is particularly applicable in overall bridge, above the said dumbbell shape structure reinforcing bars 1 for connecting described main bridge section and attachment strap 3, its one end is connected in abutment 6, and the other end is connected in attachment strap 3.
Again shown in composition graphs 1 ~ Fig. 3, now the construction method of the present embodiment is simply described below:
Before abutment 6, girder 11 and bridge deck 10 form entirety, first at the pre-buried dumbbell shape structure reinforcing bars 1 in abutment 6 place without rubber sleeve end, then cast-in-place abutment concrete; During cast attachment strap 3, rubber sleeve end is with to imbed attachment strap reserved dumbbell shape structure reinforcing bars 1; Dumbbell shape structure reinforcing bars 1 between two blocks of attachment straps 3 is embedded in attachment strap 3 simultaneously respectively, puts into polyurethane material 7 in expansion joint (E.J.), finally pours into a mould attachment strap 3 concrete.
Embodiment two: semi-monolithic bridge
Fig. 4 and Fig. 5 shows second specific embodiment that this chain type attachment strap based on seamless bridge of the utility model constructs, this routine this chain type attachment strap structure is substantially identical with the structure of embodiment one, and difference is: this chain type of the present embodiment attachment strap structure is particularly applicable in semi-monolithic bridge (but not overall bridge of embodiment one).Identical with embodiment one, for connecting the dumbbell shape structure reinforcing bars 1 of main bridge section and attachment strap 3, its one end is connected in abutment 6, and the other end is connected in attachment strap 3.
During construction, before abutment 6, girder 11 and bridge deck 10 form entirety, first at the pre-buried dumbbell shape structure reinforcing bars 1 in abutment 6 place without rubber sleeve end, then cast-in-place bridge abutment 6 concrete.
Embodiment three: extension bridge panel bridge
Fig. 6 and Fig. 7 shows the 3rd specific embodiment that this chain type attachment strap based on seamless bridge of the utility model constructs, this routine this chain type attachment strap structure is also closely similar with the structure of embodiment one, difference is: this chain type of the present embodiment attachment strap structure is particularly applicable in extension bridge panel bridge (but not overall bridge of embodiment one), for connecting the dumbbell shape structure reinforcing bars 1 of main bridge section and attachment strap 3, its one end is connected to (but not in abutment 6 of embodiment one) in bridge deck 10, and the other end is connected in attachment strap 3.
During construction, before bridge deck 10 are poured into a mould, first at the pre-buried dumbbell shape structure reinforcing bars 1 in bridge deck 10 end without rubber sleeve end, then cast-in-place bridge bridge deck concrete.
Certainly, above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to people can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, all should be encompassed within protection domain of the present utility model.
