Traction runway for automobile safety crash laboratory and layered construction method of the traction runway

Abstract

The invention provides a traction runway for an automobile safety crash laboratory. The traction runway comprises a foundation trench, a plurality of groups of supporting devices, a concrete layer and an asphalt layer, wherein the plurality of groups of supporting devices are arranged in the foundation trench and are connected with each other; the concrete layer is poured between the supporting devices and the foundation trench; the asphalt layer is paved on the upper surface of the concrete layer; each supporting device comprises a height adjusting bracket, an H-steel supporting mechanism, a plurality of H-steel reinforcing ribs and restrained steel bars, wherein the height adjusting bracket is arranged on the bottom of the foundation trench, the H-steel supporting mechanism is assembled above the height adjusting bracket, the plurality of H-steel reinforcing ribs are fixedly connected to two sides of the H-steel supporting mechanism, one ends of the restrained steel bars are connected to the H-steel reinforcing ribs, and the other end of the restrained steel bars are obliquely inserted into the restrained steel bars located in the foundation trench; the concrete layer is divided into a bottom concrete layer and a middle concrete layer, wherein the bottom concrete layer is lower than the height adjusting bracket, the middle concrete layer is poured on the bottom concrete layer, and the poured concrete layer is lower than the upper surface of the H-steel supporting mechanism. The traction runway has the beneficial effects that the flatness of the traction runway can be adjusted step by step, and asphalt is paved on the topmost layer, so that a pavement can be repaired at any time, and furthermore, the accuracy of an automobile crash test is ensured.

Description

technical field [0001] The invention relates to the technical field of automobile collision tests, in particular to a traction track for an automobile safety collision test room and a layered construction method thereof. Background technique [0002] Automobile crash test is an important means to study automobile safety. It can reproduce the collision form of vehicles under most traffic conditions, and has become an important way to test and evaluate the research of automobile passive safety. In order to reproduce the vehicle collision form in the test room, the vehicle under test needs to be accelerated from static to the specified collision speed. For the purpose of test safety, the vehicle collision test must not rely on vehicle power to accelerate the vehicle, but to use traction to make the vehicle reach the specified speed. For this reason, the design of the collision test traction runway should consider the embedded traction during road construction. Rails, used to c...

AI Technical Summary

Problems solved by technology

[0003] Referring to the general indoor ground construction technology, combined with the requirements of the embedded traction track, if the general one-time concrete pouring molding process is adopted, the problems of honeycomb, pockmarks, and dog holes caused by uneven vibration during the concrete molding process, and the hardening process Self-shrinkage problem, these uncontrollable factors will directly affect the final flatness of the ground, and this effect is irreparable, which will eventually lead to inaccurate crash tests or even failure to conduct crash tests
