Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Example is not intended to limit the scope of the present invention for illustrating the utility model.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified
Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally
Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary,
It can be the connection inside two elements.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
The concrete meaning of language in the present invention.
Straddle type monorail rail tracks are tall and thin type structure, and beam section is narrow and high, and stress performance and conventional girder have very greatly
Difference, the mobile load that track girder is born is larger, and there are biggish hogging moments at support.
Fig. 4 shows the overhead sectional view at the wet joint of the utility model straddle type monorail rail tracks；Such as Fig. 4 and Fig. 5
Shown, which includes: more bellowss and Duo Gen steel strand wires 5；Bellows is embedded in the top plate of track girder 1
It is interior, and the end interlaced arrangement of bellows is at the top plate of track girder 1, so that the end of bellows is not at the same of track girder 1
On one cross section；Neighbour across track girder 1 in bellows be connected with the bellows in wet joint at bridge pier, steel strand wires 5 pass through neighbour
Across track girder 1 in bellows and wet joint in bellows；And the end of steel strand wires 5 be anchored at respectively it is adjacent across track girder
At 1 top surface.
Specifically, bellows is then eliminated in figures 4 and 5 for the ease of display steel strand wires 5 in figures 4 and 5, but
It is that bellows is consistent with the trend of steel strand wires 5, bellows is wrapped in outside steel strand wires 5.The pre-buried bellows in 1 top plate of track girder,
Can be when track girder 1 be prefabricated, the pre-buried more bellowss in the top plate of track girder 1, it is preferable that the bellows is wavy metal
Pipe；For example, the material of the metal bellows is carbon steel, stainless steel, steel lining plastic or aluminum etc..And the end of the bellows is handed over
Mistake arrangement, i.e., the end of adjacent two bellowss is not on the same cross section of track girder 1, to avoid in the same of track girder 1
One cross-section location forms plane of weakness；That is, one end of first bellows and one end of second bellows are not at track girder 1
Same cross section on, and the other end of the other end of first bellows and second bellows is not at the same of track girder 1
On one cross section.
After track girder 1 is transported to scene, the wet joint of cast-in-place certain length on bridge pier, completing freely-supported becomes continuous
The conversion of system；And during pouring wet joint, also pre-buried more bellowss in wet joint；And the ripple in wet joint
Pipe is corresponded with the bellows in track girder 1, the bellows in wet joint is connected with the bellows in track girder 1, preferably
Ground, the connection type of the two are to be threadedly coupled.After wet joint pours, by steel strand wires 5 be interspersed in it is adjacent across 1 He of track girder
In the bellows of wet joint, by wet joint and it is adjacent across track girder 1 be connected.And the tensioning steel strand wires 5 are (that is, prestressing force
Steel strand wires 5), and the concrete sealing off and covering anchorage of same label, and the levelling anchoring face are used in the tensioning end of steel strand wires 5, so that
The top surface of track girder 1 is smooth.
Straddle type monorail rail tracks provided in this embodiment, easy construction is feasible, and there is no combine between different materials
The plane of weakness of formation；And apply prestressing force in the top plate of track girder, it is effective against the drawing that hogging moment generates at top plate and answers
Power can effectively prevent roof break, avoid rainwater intrusion from destroying beam body, and then improve the service life of track girder.
Further, width direction equidistant placement of the bellows along track girder 1.As shown in figure 4, being connect in steel strand wires 5 by wet
Head and it is adjacent across track girder 1 be linked together after, steel strand wires 5 are in lower convex.And since bellows is along the width side of track girder 1
To equidistant placement, then the steel strand wires 5 in bellows are also along the width direction equidistant placement of track girder 1, as shown in Figure 5；That is, steel twists
Line 5 is evenly arranged along the width direction of track girder 1；And since the end interlaced arrangement of bellows is at the top of track girder 1, then
In the end of steel strand wires 5 also interlaced arrangement, that is, the vertical range between the bottom of the steel strand wires 5 of the lower convex is equal, and
Vertical range between the end of the steel strand wires 5 of the lower convex is also equal, as shown in Figure 5；To increase the stress of track girder 1
Can, and then improve the reliability of the straddle type monorail rail tracks 1.
Further, straddle type monorail rail tracks, further includes: more reinforcing bars 6 being arranged in the top plate of track girder.It is excellent
Selection of land, width direction equidistant placement of the reinforcing bar 6 along track girder 1.The pre-buried bellows in the top of track girder 1, and in the wave
On the basis of interting steel strand wires 5 in line pipe, more reinforcing bars 6 are arranged, in the top plate of track girder 1 also to enhance the property of track girder 1
Can, and then improve the ability of the resist torque of track girder 1.For example, width direction equidistant cloth of the more reinforcing bars 6 along track girder 1
It sets, then the stress performance of track girder 1 can be improved, so that track girder 1 is not susceptible to deformation etc..
Further, reinforcing bar 6 and bellows arranged for interval.As shown in figure 5, reinforcing bar 6 and bellows arranged for interval, that is, first
A reinforcing bar 6 is arranged in the top plate of track girder 1, is then being arranged a bellows, is so being recycled, and intert in bellows
Steel strand wires 5 can then form spaced apart reinforcing bar 6 and steel strand wires 5.And it is twisted due to having been provided with steel in the top plate of track girder 1
Line 5, and then the dosage of reinforcing bar 6 can be suitably reduced, while guaranteeing 1 performance of track girder, it can accordingly reduce the number of reinforcing bar 6
Amount, achievees the purpose that save the cost.
