Description
Technical field
The utility model relates to bridge construction field, particularly relates to a kind of tram plate-girder.
Background technology
Tram adopts driven by power and the light-duty little marshalling rail traffic vehicles travelled in orbit.Tram is a kind of public transport, also known as streetcar or abbreviation electric car, belongs to the one of light railway.Because electric car promotes relation with electric power, vehicle can not discharging waste gas, because of but a kind of free of contamination environmental protection vehicles.In recent years, tram, as a kind of novel urban track traffic mode, obtains swift and violent development.
The feature that street railway lays is laid based on bottom surface, and how to lay along in the road of existing road, often will run into the situation that circuit passes through in the middle of current highway and bridge like this, need to reinforce the mid portion of current highway and bridge or remove, then redesign the bridge of tram.
Tram bridge is due to the requirement such as degree of disturbing, natural frequency, and deck-molding generally can not be too little.Because century-old water level has requirement to bottom elevation, should flush with highway bridge at the bottom of beam.For existing little span highway bridge, because the little span simply supported slab girder construction height of road bridge is less, and the way of the tram bridge of routine lays track structure, even if tram bridge can be accomplished the same with the structure height of highway bridge like this, also be difficult to reach track level measuring concordant with current highway and bridge absolute altitude, thus can not realize the mixing right of way on bridge, also affect the attractive in appearance of bridge construction.
Therefore, be necessary to provide a kind of can realize mixing right of way and structure tram plate-girder attractive in appearance to overcome above-mentioned defect.
Utility model content
The purpose of this utility model is to provide and a kind ofly can realizes mixing right of way and structure tram plate-girder attractive in appearance.
To achieve these goals; the utility model provides a kind of tram plate-girder and comprises the plate-girder main body being equipped with waterproofing course and topping successively; two pairs of notches are offered in plate-girder main body; the groove width of each notch is 0.5 ~ 1m; the groove depth of each notch is 0.32 ~ 0.36m; be equipped with track in each notch, track is equipped with track, the end face of track, the end face of plate-girder main body are concordant with the bridge floor of existing road bridge.
Preferably, wherein the axis of symmetry of a pair notch and another be 4 ~ 4.5m to the distance between the axis of symmetry of notch.
Preferably, the groove width of notch is 0.7m, and the groove depth of notch is 3.4m.
Preferably, waterproofing course is made up of polyurethane water-proof paint.
Preferably, topping is made up of C40 fibrous concrete.
Compared with prior art; on the one hand; tram plate-girder of the present utility model is creationary slots at back; and track structure is imbedded in notch; namely be built in Liang Tizhong, greatly reduce the rail level absolute altitude of circuit, thus make the slab and girder back absolute altitude after waterproofing course and topping of having constructed consistent with rail level absolute altitude; and then achieve tram bridge and highway bridge mix right of way, and save construction investment.On the other hand, when adopting tram slab and girder of the present utility model, only need the plate-girder removing existing road bridge in tram width range, there is higher economic benefit and social benefit.
By following description also by reference to the accompanying drawings, the utility model will become more clear, and these accompanying drawings are for explaining embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation that tram plate-girder of the present utility model is located on bridge pier.
Fig. 2 is the structural representation of the plate-girder main body in Fig. 1.
Fig. 3 is the flow chart of the construction method of tram plate-girder of the present utility model.
Detailed description of the invention
With reference now to accompanying drawing, describe embodiment of the present utility model, element numbers similar in accompanying drawing represents similar element.
As shown in Figure 1-2, the tram plate-girder of the present embodiment comprises the plate-girder main body 10 being equipped with waterproofing course and topping successively, and plate-girder main body 10 is located on bridge pier 20.Two pairs of notches 11 are offered in plate-girder main body 10, wherein the axis of symmetry X-X of a pair notch 11 and another be 4.2m to the distance L ' between the axis of symmetry Y-Y of notch 11, the groove width L of each notch 11 is the groove depth H of each notch 11 of 0.7m is 0.34m, and be equipped with track 12 in each notch 11, track 12 is equipped with track 13, the end face of track 13, the end face of plate-girder main body 10 are concordant with the bridge floor of existing road bridge (not shown).Waterproofing course (not shown) is made up of polyurethane water-proof paint.Topping (not shown) is made up of C40 fibrous concrete.
With reference to figure 3, the construction method of tram plate-girder of the present utility model comprises the steps:
S1, after substructure construction completes, according to the plan-position of circuit, determines slotting position in plate-girder main body 10 and according to the dimensional requirement of track 12, determines the size of the notch 11 that plate-girder main body 10 is offered;
S2, colligation indented bars, fixed form, reserves the space of notch 11 and needs pre-buried track structure connecting reinforcement at slotting position place;
S3, concreting on reinforcing bar, template and track structure connecting reinforcement prestressed reinforcement of tensioning bundle, thus form plate-girder main body 10, plate-girder main body 10 is formed with two pairs of notches 11, wherein the axis of symmetry of a pair notch 11 and another be 4.2m to the distance between the axis of symmetry of notch 11, the groove width of each notch 11 is 0.7m, and the groove depth of each notch 11 is 0.34m;
S4, assembling reinforcement in notch 11 concreting, re-lay track 13 structure, the track 13 that track 13 structure comprises track 12 and is located on track 12;
S5, plate-girder main body 10 lays waterproofing course and topping successively, and waterproofing course is made up of polyurethane water-proof paint, and topping is made up of C40 fibrous concrete, and after laying, the end face of track 13, the end face of plate-girder main body 10 are concordant with the bridge floor of existing road bridge.
More than in conjunction with most preferred embodiment, the utility model is described, but the utility model is not limited to the embodiment of above announcement, and should contain various carry out according to essence of the present utility model amendment, equivalent combinations.
