Abstract
The utility model discloses a low-speed and medium-speed magnetic suspension linear track beam. A beam body has reliable transverse stability; an anti-drawing support is not needed; the beam body is easy and convenient to construct; and engineering cost can be reduced. The low-speed and medium-speed magnetic suspension linear track beam comprises the beam body (10) and supports (20) arranged at the top of a pier (30), wherein the beam body (10) is linear; the section of the beam body (10) is a rectangular box-type section consisting of a top plate (13), a base plate (14) and two side web plates (11 and 12); and steel concrete bases (15) are arranged at the bottoms of two ends of the beam body (10), which correspond to the supports (20), and extend out of the two side web plates (11 and 12) along the transverse direction of the beam body (10) to form an integrated structure together with the beam body (10).
Description
Technical field
The utility model relates to rail beam, particularly a kind of middle low speed magnetic floating rectilinear orbit beam.
Background technology
In the magnetic levitation track traffic, vehicle needs " embracing beam " operation, and the beam body is narrower usually, and lateral stability is relatively poor.Rail beam form of structure commonly used at present mainly contains trapezoidal box girder and two kinds of form of structure of the little case beam of U-shaped.
Trapezoidal box girder; The cross section is the trapezoidal of " up-small and down-big ", and the base plate broad also has the edge of a wing, though this kind form of structure can be drawn back the lateral stability of subplate bearer lateral arrangement spacing, increase beam body; But base plate is provided with the edge of a wing and widens base plate, causes the engineering quantity of beam body to increase; The elongated setting in the base plate edge of a wing simultaneously, concreting and vibrate and all compare difficulty, beam phantom plate is removed and is also very easily caused concrete peeling off, and is difficult to the assurance construction quality.
The little box-beam structure of U-shaped is a bridge construction form commonly used in the middle low speed magnetic floating track traffic, and this beam all is " U " shape along beam length direction total cross-section, and only rounding is handled at the bottom of support position place cancellation beam, makes rectangle.Because the beam body is narrower, the subplate bearer spacing is less, and in order to keep the lateral stability of beam body, rail beam bearing must adopt the anti-pulling bearing.When rail beam is positioned on the longitudinal gradient be, the beam body tilts, and must adopt different bearing pre-embedded steel slabs, adjusts the longitudinal gradient of rail beam, and installing to bearing makes troubles.
The utility model content
The utility model technical problem to be solved provides a kind of middle low speed magnetic floating rectilinear orbit beam, and the reliable lateral stability of Liang Tiyou need not to adopt the anti-pulling bearing, and the beam body is succinct, convenient construction, helps reducing construction costs.
It is following that the utility model solves the technical scheme that its technical problem adopted:
The middle low speed magnetic floating rectilinear orbit beam of the utility model; Comprise that Liang Tihe is arranged at the bearing at bridge pier top; It is characterized in that: said beam body is by straight line; The rectangle box-type section that is made up of top board, base plate (14) and two coxostermums is adopted in its cross section, at beam body two ends and the corresponding bottom of bearing reinforced concrete footing is set respectively, reinforced concrete footing along the beam body laterally to two coxostermum extensions stretch and with beam body formation overall structure.
The beneficial effect of the utility model is that the beam body is succinct, convenient construction, helps reducing construction costs; Bearing lateral arrangement spacing is big, and the reliable lateral stability of Liang Tiyou need not to adopt the anti-pulling bearing, is convenient to selecting for use and installing of bearing; Rail beam is strong to circuit longitudinal gradient adaptive capacity, reasonable stress, and convenient adjustment beam body inclination angle, no specific (special) requirements is selected and installed to circuit longitudinal gradient location bearing for use.
Description of drawings
This manual comprises following three width of cloth accompanying drawings:
Fig. 1 is the structural representation of low speed magnetic floating rectilinear orbit beam in the utility model;
Fig. 2 is the sectional drawing along A-A line among Fig. 1;
Fig. 3 is the sectional drawing along B-B line among Fig. 1.
Member shown in the figure, toponym and pairing mark: beam body 10, web 11, web 12, top board 13, base plate 14, reinforced concrete footing 15, bearing 20, bridge pier 30.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
With reference to Fig. 1 and Fig. 3; The middle low speed magnetic floating rectilinear orbit beam of the utility model; Comprise beam body 10 and the bearing 20 that is arranged at bridge pier 30 tops, said beam body 10 is by straight line, and the rectangle box-type section that is made up of top board 13, base plate 14 and two coxostermums 11,12 is adopted in its cross section; At beam body 10 two ends and bearing 20 corresponding bottoms steel concrete 15 is set respectively; Reinforced concrete footing 15 laterally extends outside two coxostermums 11,12 and constitutes overall structures with beam body 10 along beam body 10, i.e. reinforced concrete footing 15 and beam body 10 steel bar overall bindings, and concrete is integrated poured.Beam-ends is provided with reinforced concrete footing 15, is convenient to draw back bearing 20 and arranges horizontal spacings, need not to adopt the lateral stability that has improved beam body 10 under the prerequisite of anti-pulling bearing.Height Δ h through adjustment beam-ends concrete bed; Can conveniently adjust the angle of inclination of beam body 10. beam-ends cross section and beam body top and bottom after beam body 10 tilts still keep vertical relation; Avoid being provided with vertical beam and be sewn on beam-ends formation acuter angles, more reasonable stress.Reinforced concrete footing 15 soffits are with respect to beam body 10 levels, and bearing 20 is easy for installation.
With reference to Fig. 2 and Fig. 3, for guaranteeing the reliability of beam-ends beam body 10 to reinforced concrete footing 15 power transmissions, said beam body 10 is provided with the position at the beam-ends reinforced concrete footing, the thickness thickening of its top board 13, base plate 14 and two coxostermums 11,12.With reference to Fig. 2, for making beam body 10 cross sections succinct, convenient construction, between two reinforced concrete footings 15 of said beam body 10 two ends, the intersection circle of position of two coxostermums 11,12 and base plate 14 slips over and crosses.
Some principles of low speed magnetic floating rectilinear orbit beam in the above the utility model that just explains through diagrams; Be not be to the utility model be confined to shown in described concrete structure and the scope of application in; So every the modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
