Bolt-connection-free assembled bridge guardrail
The invention discloses a bolt-connection-free assembled bridge guardrail. The bolt-connection-free assembled bridge guardrail comprises fixed bases and hollow pipe stand columns which are sequentially arranged at intervals, and transversely-arranged connecting rods are arranged between the hollow pipe stand columns; a connecting pipe extending to the interior of the corresponding hollow pipe stand column is vertically arranged on each fixed base, and through holes are formed in the lower portions of the two sides of each hollow pipe stand column; guide holes corresponding to the through holes and limiting rods arranged in the guide holes are arranged on the side faces of the connecting pipes, and the outer portions of the limiting rods are sleeved with springs; and downward slope surfaces are arranged at the tail ends of the limiting rods. Through the manner, by means of the bolt-connection-free assembled bridge guardrail, the slope surfaces are utilized for pushing the limiting rods to the interiors of the connecting pipes, and after the hollow pipe stand columns descend to the bottoms, the through holes are communicated with the guide holes to enable the limiting rods to be pulled into the through holes under the effect of the springs; displacement of the hollow pipe stand columns is limited, and the bridge guardrail is rapid in construction, firm in structure, attractive in appearance and convenient to maintain.
