Embodiment 1

[0022] Such as figure 1 , figure 2 As shown, the novel detachable road guardrail is applied to urban roads, and the novel detachable road guardrail is applied to urban roads, including a column 1, an upper beam 2, a lower beam 3 and multiple Two pillars 4 are arranged vertically side by side at intervals between the upper beam 2 and the lower beam 3, the upper beam 2 and the lower beam 3 are arranged in parallel, and the two ends of the upper beam 2 and the lower beam 3 are fixedly connected to the column 1. The column 1 is installed on the ground, and it is characterized in that: the column 1 includes an end cover 11, a cylindrical pole 12 and a base 13 arranged in sequence from top to bottom; the upper beam 2 and the lower beam 3 are all metal materials The prepared rectangular plate, and both ends of the upper beam 2 and the lower beam 3 are provided with through holes, and the two ends of the upper beam 2 and the lower beam 3 are sleeved on the vertical rod 12 through th...

Embodiment 2

[0027] This embodiment is improved on the basis of Embodiment 1. The improvement is that: both ends of the pillar 4 are provided with external threads, and the pillar 4 is connected with the upper beam 2 and the lower beam 3 by threads, so that It is detachably fixed between the upper beam 2 and the lower beam 3, which is convenient for the installation and replacement of the guardrail pillar 4.

[0028] The pillar 4 is a cylindrical pillar 4 made of stainless steel, the upper beam 2 and the lower beam 3 are square beams made of elastic metal materials, and the two ends of the upper beam 2 and the lower beam 3 are detachably connected to the column 1 , to facilitate the disassembly and installation of the guardrail. At the same time, the upper crossbeam 2 and the lower crossbeam 3 are made of elastic metal materials, which can play a buffering role for vehicles that vertically hit the guardrail, so that the deformation of the elastic metal material can eliminate part of the co...

Embodiment 3

[0031] This embodiment is improved on the basis of Embodiment 2. The improvement is that: the upper beam 2 includes a fixing part arranged below and a covering part straddling the fixing part, and the upper surface of the fixing part Recess downwards to form a fixing groove, in which the pillars 4 are equidistantly provided with threaded holes, and the upper end of the pillars 4 is fixedly connected with the upper beam 2 through the threaded holes; The width of the cover groove, the cover part is covered above the fixed part by screws. The fixing groove and the cover groove constitute an installation space with a rectangular cross-section for installing the pillar 4. At the same time, the cover part can place the installation position of the pillar 4 in a closed space to avoid exposure to wind and rain for a long time. , The mounting position of the pillar 4 is easy to rust and damage.

[0032] Other parts in this embodiment are basically the same as those in Embodiment 2, so...

Abstract

The invention discloses a novel detachable road guardrail, which includes a column, an upper cross beam, a lower cross beam and a plurality of pillars arranged vertically and side by side between theupper cross beam and the lower cross beam, wherein the upper cross beam and the lower cross beam are arranged in parallel, two ends of the upper cross beam and the lower cross beam are fixedly connected with the column, and the column is installed on the ground. An anti-collision sleeve capable of rotating about the axis of the pillar is sleeved on the pillar, a plurality of rack bars extending along the longitudinal direction are arranged on the surface of the anti-collision sleeve, and the rack bars on the anti-collision sleeve sleeved on the adjacent pillar are mutually engaged; The anti-collision sleeve is a rubber anti-collision sleeve or a silica gel anti-collision sleeve with coarse particles arranged on the surface. The invention can effectively absorb the collision kinetic energyof the vehicle and the guardrail, make the vehicle stop quickly, and effectively reduce the loss caused by the traffic accident.

Description

technical field [0001] The invention relates to the technical field of municipal construction, in particular to a novel detachable road guardrail. Background technique [0002] Due to the rapid development of economy and urbanization, the number of private cars is also increasing rapidly, and the frequency of traffic accidents is also increasing. In urban roads, because the roads are criss-crossed and there are many vehicles, the frequency of traffic accidents is higher than that of expressways. However, due to the speed limit, the human and property losses caused by its traffic accidents are also much smaller. [0003] In order to reduce the occurrence of traffic accidents and quickly reduce the speed of the vehicle involved in the accident, road guardrails are often set up in urban roads. However, due to the needs of urban construction or urban environment decoration, its road guardrails often need to be replaced. [0004] Existing road guardrails include detachable gua...
