Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood at this with concrete condition
Concrete meaning in invention.
Below with reference to the accompanying drawings pre-track beam 1 according to an embodiment of the present invention for straddle-type rail vehicle is described.
As Figure 1-Figure 4, the pre-track beam 1 according to an embodiment of the present invention for straddle-type rail vehicle includes real
Heart beam 10 and multiple presstressed reinforcing steels 20.Wherein, straddle-type rail vehicle refers to, the bogie straddle seat of vehicle bottom is in track girder
On, which coats downwards track girder from the two sides of track girder, for example, straddle-type single-track vehicle, straddle-type double track vehicle.
Solid beam 10 is solid construction, i.e. hollow rate is zero, and solid beam 10 can be solid concrete beam.Each prestressing force
Muscle 20 runs through solid beam 10, for same presstressed reinforcing steel 20, the middle part of presstressed reinforcing steel 20 along the length direction of solid beam 10
Lower than the both ends of presstressed reinforcing steel 20.
Wherein, the cross-sectional area sum of multiple presstressed reinforcing steels 20 accounts for the 0.67%- of the overall cross sectional area of pre-track beam 1
1.03%, i.e. the ratio of reinforcement of pre-track beam 1 is 0.67%-1.03%.
Also, as shown in Figure 3 and Figure 4, there is presumptive area A, presumptive area A is away from solid beam in the cross section of solid beam 10
The distance of 10 upper surface and the high ratio of solid beam 10 are 0.44, the distance of lower surface of the presumptive area A away from solid beam 10
High ratio with solid beam 10 is 0.18, and the Resultant force of multiple presstressed reinforcing steels 20 is located in presumptive area A.
It will be appreciated by those skilled in the art that ground is, the Resultant force of multiple presstressed reinforcing steels 20 refers to, multiple presstressed reinforcing steels
20 in solid beam 10, a resultant force is formed when bearing load, the position of the resultant force is Resultant force.
Specifically, pre-track beam 1 is during installation, pulling force is applied to presstressed reinforcing steel 20 at the both ends of pre-track beam 1,
Under the pulling force effect, middle part is moved upwards at the both ends of presstressed reinforcing steel 20, keeps the middle part of solid beam 10 upward convex, to offset vehicle
Pressure.
Pre-track beam 1 according to an embodiment of the present invention for straddle-type rail vehicle, by using solid construction
Solid beam 10 eliminates the influence that internal cavity arranges presstressed reinforcing steel 20, and the cross-sectional area of multiple presstressed reinforcing steels 20 is arranged
The sum of account for pre-track beam 1 overall cross sectional area 0.67%-1.03%, and the conjunction of multiple presstressed reinforcing steels 20 is further set
Force is located in presumptive area A, and the distance of upper surface of the presumptive area A away from solid beam 10 is with the high ratio of solid beam 10
The distance of the lower surface of 0.44, presumptive area A away from solid beam 10 and the high ratio of solid beam 10 are 0.18.It changes as a result,
The arrangement of multiple presstressed reinforcing steels 20 reduces the resultant force position of multiple presstressed reinforcing steels 20, to increase the pre- of the offer of presstressed reinforcing steel 20
Stress, and then reduce the usage amount of presstressed reinforcing steel 20, to simplify construction technology, reduce costs.
Also, pre-track beam in the related technology, since beams of concrete forms hollow structure using reinforcing bar establishment cavity,
And cavity domestic demand filled internal mold, in this way from the point of view of the horizontal cross-section of beams of concrete, since steel strand wires need to avoid hollow parts,
Steel strand wires need to be bent outwardly, and further increase the difficulty of construction technology.
And the pre-track beam 1 according to an embodiment of the present invention for straddle-type rail vehicle, using the reality of solid construction
On the one hand heart beam 10 is not necessarily to process chamber and filled internal mold, another aspect presstressed reinforcing steel 20 is not necessarily to bending in horizontal direction, i.e.,
As shown in Fig. 2, the length direction of presstressed reinforcing steel 20 is parallel to the length side of solid beam 10 in the horizontal cross-section of solid beam 10
To.Thus, it is possible to keep the arrangement of presstressed reinforcing steel 20 more flexible, construction technology difficulty further reduced.
