Embodiment

[0027] see Figure 1 to Figure 4 , the present invention includes a curb 1 for installing a railing 4 and a railing 4 that is arranged on the curb 1 and plays a daily safety protection role. The side of the curb 1 near the road is provided with three sets of installation grooves 2, and the installation groove 2 A buffer seat 3 for installing a railing 4 is provided inside, and the railing 4 is arranged on the buffer seat 3 . One end of the mounting groove 2 close to the road communicates with the outside of the curb 1 and is open, and the end of the mounting groove 2 away from the road is provided with a buffer surface 21 for buffering the load of the railing 4 . The buffer surface 21 is inclined to the bottom of the installation groove 2 and the angle between the buffer surface 21 and the bottom of the installation groove 2 is an obtuse angle.

[0028] see further figure 2 with Figure 4 , the buffer seat 3 includes an installation shaft 31 arranged in the installation gr...

Abstract

The invention discloses a folding guardrail and belongs to the field of guardrails. The folding guardrail comprises a kerb, a plurality of groups of installation grooves formed in the kerb, buffer seats arranged in the installation grooves and railings arranged on the buffer seats. One ends of the installation grooves are in communication with the outside of the kerb, the other ends of the installation grooves are provided with buffer surfaces, and the buffer seats comprise installation shafts arranged in the installation grooves and fixedly connected with the installation grooves, sleeves arranged outside the installation shafts in a sleeving mode and connected with the installation shafts in a rotating mode, and force transfer blocks arranged between the sleeves and the buffer surfaces.The folding guardrail is easy to operate and convenient to use. The railings can not only play a daily safety protection role and reduce the damage rate of the railings in the flood and tsunami disasters, but also reduce the stress on a bridge when the flood and tsunami disasters occur.

Description

technical field [0001] The invention relates to the field of guardrails, in particular to a foldable guardrail. Background technique [0002] Under the influence of the continental monsoon climate in most parts of China, the rainfall is concentrated in time and intensity. Affected by climate and geographical conditions, my country's flood disasters have the characteristics of wide range, frequent occurrence, strong suddenness, and large losses. Highway bridges or small-span railway bridges on provincial roads and township-level roads in my country often suffer from floods. The southeast coast of my country also has a high risk of tsunami, and small-span coastal bridges or bridges in coastal cities have a high risk of being damaged by tsunami. [0003] When the bridge is subjected to flood disaster or tsunami disaster, the flood, tsunami and its mixed floating objects are very destructive to the bridge, and the flood and tsunami force on the railing accounts for a very larg...
