There is a traveling-type vehicle weight sensor of a capacitance type using a mat having a sandwich-like shape and utilizing a change in capacitance between the conductive sheets A and C due to a treading load of the vehicle. Japanese Patent Application No. 50-19057, Japanese Utility Model Application No. 3-106429). As other traveling vehicle weight sensors, there are those which are mounted on a road surface with a conductive rubber sensor whose volume resistance changes with the treading load of the vehicle, and those which use a strain gauge.

The special dummy plate 33, the mat-shaped vehicle weight sensor 31, and the cable protector 35 are fixed to the road surface in this order with an adhesive tape or the like in the traveling direction of the vehicle. The signal obtained from the vehicle weight sensor 31 is connected to a data processing unit 37 by a cable passed through a cable protector 35. In this conventional example, not only a level difference due to the thickness of the weight sensor portion and the like occurs, but it is not suitable for performing highly accurate weight detection on the traveling vehicle.

トを使用することになり、工事費用も増大する。As another conventional example, there is one in which a concave portion for embedding a metal sensor such as a vehicle weight sensor and a loop sensor is cut on a flat road surface, and a weight sensor and the like are installed in the concave portion. In this conventional example, not only is it necessary to perform a period for cutting the road surface and curing after installing the weight sensor (usually, the curing time of the frame adhesive takes 7 days), but also to improve the measurement accuracy. Although the road surface is required to be flat for several tens of meters in front of and behind the weight sensor, a great deal of construction time and costs are required to correct the road surface. By the way, in road construction, night construction is normally performed in order to prevent traffic jam of vehicles. When the installation work of the conventional vehicle weight sensor and the like is performed by night work, the curing period after the installation cannot be sufficiently taken, and the work time increases, so that the construction cost also increases. Furthermore, when a new road surface is made, special concrete is used in order to shorten the road closing period, and the construction cost is increased.

要になるという問題点があった。As described above, in the conventional traveling vehicle weight measuring apparatus, a high-precision measuring apparatus cannot be obtained with an inexpensive apparatus having a short construction period. If so, there is a problem that a great deal of construction time and cost are required.

にも、容易に調整できるメリットもある。When the running vehicle weight measuring device configured as described above is used, since the pre-concrete board is manufactured in the factory, it is possible to take enough time for curing when mounting the weight sensor. In addition, a road surface having high quality and excellent flatness (finishing a road surface having a high flatness between 60 m and 70 m) can be made in a short time and at low cost. Further, there is a merit that even when the flatness changes during the long-term use, it can be easily adjusted.

A vibration absorbing adhesive is used as a joint 7 at the joint of each pre-concrete board 1. The joint 7 and the cushioning material 5 made of the vibration-absorbing material make it difficult for the vibration generated when the vehicle passes to be transmitted to the adjacent pre-concrete plate, thereby improving the accuracy of weight measurement.

A flat road surface is formed by a pre-concrete disk at 0 m and on the rear side in the traveling direction, about 20 m. When forming a road surface with a pre-concrete plate, not only can high quality and high flatness be prepared beforehand in the factory,
At a construction site, a road surface can be adjusted easily and in a short time by using a height adjusting screw or the like, which is extremely effective in measuring the weight of a traveling vehicle that requires a road surface with a high flatness. Also, when the flatness changes during long-term use, it can be easily corrected. Furthermore, by fixing the pre-concrete board with screws or bolts, it becomes easier to adjust the road surface and correct the flatness when it is out of order.

In the process of manufacturing the pre-concrete board, a recess is formed in the surface of the pre-concrete board by a similar method, and a loop sensor is inserted into the recess and sealed with a filling / adhesive material. Since a reinforcing steel bar cannot be used for this pre-concrete disk, it is preferable to reinforce it with a reinforcing material made of a non-metallic material such as glass fiber which does not feel magnetism. Also in this case, similarly to the above, the curing time can be sufficiently set, and the loop sensor can be accurately installed.
