Prefabricated municipal protective column

Abstract

The invention belongs to the technical field of municipal prefabricated parts, and particularly relates to a prefabricated municipal protective column which comprises a column body, a mounting cavity, mounting rods, reinforcing columns, mounting grooves, a corrugated plate and an impact block. The column body is arranged in a square column shape, and the mounting cavity is formed in the column body; the mounting rods are fixedly connected to the inner surfaces of the upper and lower middle parts of the mounting cavity; the middle parts of the mounting rods are fixedly connected with the reinforcing columns; a mounting plate is arranged on the outer sides of the reinforcing columns; the wall surfaces of the front end and the rear end of the mounting plate are fixedly connected into the mounting grooves, and inserting pipe groups are vertically symmetrically and slidably connected between the mounting plate and the reinforcing columns; when a linkage pipe rotates, a rotating wheel is driven to rotate, so that an arc-shaped plate rotates in a small range under the meshing action of sawteeth, clamping teeth connected to the outer end of the arc-shaped plate are pushed to rotate outwards, the clamping teeth are promoted to be clamped into grooves in the outer wall of a pulling plate, and the cohesion effect on the pulling plate is further improved; and the overall protection performance of the protective column is greatly enhanced.

Description

technical field [0001] The invention belongs to the technical field of municipal prefabricated parts, in particular to a prefabricated municipal bollard. Background technique [0002] Bollards are also called column guardrails. Traffic safety signs set on the higher approach roads at both ends of the bridge and on the sharp bends, steep slopes, cliffs, etc. of high embankments of high-grade highways. Generally, prefabricated concrete or masonry materials are used for masonry, and one is set at a certain distance, and the exposed part of the ground is painted with red, white or black and white at intervals to give drivers and passengers a sense of eye-catching and safe. It is usually also set up on flood bridges without sidewalks. [0003] In cities, bollards are usually set up at the separation between sidewalks and roads. On the one hand, it is to prevent cars from entering the pedestrian passage, and on the other hand, it is also to protect pedestrians from getting out o...

Problems solved by technology

[0003] In cities, bollards are usually set up at the separation between sidewalks and roads. On the one hand, it is to prevent cars from entering the pedestrian passage, and on the other hand, it is also to protect pedestrians from getting out of control and hurting pedestrians. In the land, this causes the out-of-control vehicle to hit the bollard and easily break it or tilt it to cause the vehicle to enter the pedestrian passage, which is not conducive to the protection of pedestrians
