Weight beam (1), weighing sensor (2) and stopping means (3) composition, wherein the upper surface of variable cross-section spandrel girder (1) is load plane,
It is concordant with both sides road surface；Weighing sensor (2) is arranged on the both ends of variable cross-section spandrel girder (1), and the spandrel girder is supported for fixed,
The weight information of its carrying is obtained simultaneously；Stopping means (3) is arranged on variable cross-section spandrel girder (1) between ground or framework and had
There is shock-absorbing capacity (including buffer unit), for limiting the moving range of variable cross-section spandrel girder (1) in the horizontal plane, reduce simultaneously
The Oscillation Amplitude of the spandrel girder, increase the stability of structure.
Preferably, the variable cross-section spandrel girder upper surface is concordant with road surface, the distance between its both sides and ground (5,
50) in the range of mm, ensure vehicle smooth ride, avoid the influence of horizontal impact.
Fig. 2 is the cross section of a kind of structural side view of embodiment of the present utility model, wherein variable cross-section spandrel girder (1)
For rectangle, by the different web beam of its lower surface additional length so that its cross-sectional area from spandrel girder both ends thereto
Between gradually increase, it is therefore an objective to reduce spandrel girder deformation, extend product service life；In addition, at the both sides both ends of the spandrel girder point
Not An Zhuan stopping means (3), on the one hand limit its displacement in the horizontal direction, on the other hand increase the stability of structure, reduce
