Light-reflecting mark for pavement construction

Abstract

The invention provides a light-reflecting mark for pavement construction including the card body, a support plate arranged below the card body and a brace arranged at the rear side of the card body, acard body includes a triangular frame, a light reflecting plate embedded in the frame and a light emitting body provided on the surface of the light reflecting plate, a support plate is in that formof a strip plate, the middle part of the supporting plate is pivotally connected with the bottom end of the card body through a fixing part, so that it can be arranged at two angles parallel to or perpendicular to the card body, the fixing member is positioned above the bottom end of the card body, which comprises a bolt threaded between the bottom end of the card body and the middle part of the support plate, a spring sleeved on the bolt and a nut screwed to the top of the bolt, the spring is clamped between the nut and the bottom end of the card body, one end of the brace rod is pivotally connected with the back surface of the card body, and the other end can be rotated to abut against the vertical support plate. The surface of the reflective plate is provided with a reflective film, which comprises a flexible transparent base layer, a retroreflective layer and a weathering layer. The pavement construction uses the reflective sign to realize the stable support of the plate body and prevent the plate body from being overturned due to the influence of the wind and the like.

Description

technical field [0001] The invention relates to a sign board, in particular to a reflective sign for road construction. Background technique [0002] During the road maintenance construction, the signs play the role of guiding vehicles to pass, protecting the safety of construction workers, and preventing outsiders from entering the construction site by mistake, causing casualties. The existing reflective signs for road construction are only a similar cone-shaped seat structure. Under the action of natural wind and the tail airflow produced by the fast passing of trucks, the construction signs will be blown down, thus causing the driver to fail. Forecasting the construction information ahead will easily lead to traffic accidents in the case of overtaking and speeding, which needs to be improved. Contents of the invention [0003] The invention proposes a reflective sign for road surface construction, which solves the problems in the prior art that the signboard is easily ...
