Indication board for roads and bridges

Abstract

The invention discloses an indication board for roads and bridges. The indication board comprises a first supporting rod and an indication panel, wherein the indication panel comprises at least one connecting plate; a first connecting rod is arranged at the end, facing the first supporting rod, of the top of the connecting board; a first groove is formed in the end, away from the first connectingrod, of the top of the connecting board; a first connecting sleeve is arranged in the first groove; the first connecting rod can be inserted into the first connecting sleeve so that the plurality of connecting plates are connected with one another. The size of the indication panel can be conveniently adjusted; waste of resources is effectively avoided; a first fixing part and a second fixing partare respectively arranged between the end surfaces of two adjacent connecting plates; the side face, back on to the first fixing part, of the first fixing part is flush with the back faces of the connecting boards; the side face, back on to the first fixing part, of the second fixing part is flush with the front faces of the connecting boards; the first fixing part and the second fixing part are clamped, and the stability of mutual combination of every two adjacent connecting boards is improved.

Description

technical field [0001] The invention relates to the technical field of road and bridge construction, in particular to a road and bridge sign. Background technique [0002] Nowadays, with the continuous improvement of the economic level, my country's transportation construction is developing more and more rapidly, and the number of roads and bridges is increasing. After the completion of the construction of roads and bridges, various indicating devices will be installed. The indicating devices usually include The support frame and the indicator plate set on the top of the support frame, when the road needs to be widened, the indicator plate also needs to be enlarged accordingly. At this stage, most of the indicator plates are formed in one piece, and the whole indicator plate needs to be replaced, resulting in In addition, the existing implementation of splicing between multiple billboards directly uses two straight-line long rods to connect the top and bottom ends of multiple ...

Problems solved by technology

[0002] Nowadays, with the continuous improvement of the economic level, my country's traffic construction is developing more and more rapidly, and the number of roads and bridges is increasing. After the construction of roads and bridges is completed, various indicating devices will be installed. The indicating devices usually include When the road needs to be widened, the supporting frame and the indicating board installed on the top of the supporting frame also need to be enlarged accordingly. At this stage, most indicating boards are integrally formed, and the indicating board needs to be replaced as a whole, resulting in A certain degree of waste of resources, in addition to the existing splicing between multiple billboards directly using two in-line long rods to connect the top and bottom of multiple billboards in series, this method needs to be connected on the back of each billboard Welding multiple rings for the long rod to pass through will undoubtedly increase the quality of the entire billboard and the longer rod body will increase the difficulty of disassembly, and generally only the front of the billboard will be painted, and the ring on the back is easier There is a risk of rust, and multiple rings can also cause problems such as accidental collision damage when billboards cannot be stacked flat during transportation
