Abstract
The utility model discloses a reinforced and reformed structure of a W-shaped beam guardrail, which aims to improve the anti-collision performance of the established W-shaped beam guardrail with low anti-collision grade, so as to meet the requirements of current domestic specifications on the anti-collision performance of the guardrail, recycle the existing W-shaped beam guardrail components, and save reforming and establishing cost. The reinforced and reformed structure of the W-shaped beam guardrail consists of a vertical column, a W-shaped plate, a reinforced beam, an anti-resistance component and a connecting component, wherein the vertical column is either the heightened part of the existing guardrail, a newly-piled vertical column, or the alternate combination of the both; the heightened part of the existing guardrail is obtained by mounting an inner sleeve and adding an outer sleeve at the top part thereof; the W-shaped plate is a double-W-shaped plate or a three-W-shaped plate of the existing guardrail, and is connected with the vertical column through the anti-resistance component and the connecting component; and the reinforced beam is arranged above the W-shaped plate and connected with the W-shaped plate and the anti-resistance component through the connecting component.
Description
Technical field
The utility model relates to highway traffic safety facility field, particularly relates to the transformation of wave beams of highway guardrail, is used to improve the crashworthiness of corrugated beam barrier.
Background technology
Guardrail is the last barrier that highway traffic safety ensures, when the crashworthiness of guardrail does not meet the demands, will be run-off-road behind the Vehicular impact guardrail or pass through in divide and be with, will cause the serious casualties and the accident of property loss.Therefore, key, particularly road speed that rational guardrail is guarantee driving safety speedway faster is set.
Along with China's rapid development of economy, the highway construction career development is rapid, and people improve constantly the requirement of highway traffic safety level.In order to adapt to the fast development of traffic, Department of Transportation has issued revision version " highway traffic safety facilities design standard " (JTG D81-2006), " highway traffic safety facility construction technique normalizing " (JTG F71-2006), " freeway traffic engineering and the facilities design general specification along the line " related specifications such as (JTG D80-2006) of " expressway traffic safety facilities design and construction technical specification " (JTJ 074-94) in 2006, its principal character is largely security protection facility anti-collision level to be promoted.Like this, the guardrail anti-collision level of the highway that began to build before 2006 will not meet the current specifications requirement, then in the overhauling reform process on old road, need transform guardrail, to improve its crashworthiness, reach the requirement of current specifications.
The most direct mode of transformation to guardrail is exactly that original guardrail is removed, and build again by the current specifications requirement, but such reforming mode cost is very high again, and causes the wide variety of materials waste, does not meet the theory that conservation-minded society and low carbon ring are protected.Particularly for corrugated beam barrier, its most of old member is all more intact, can reuse.Therefore, develop the improvement cost that a kind of crashworthiness satisfies the current specifications requirement, the corrugated beam barrier reconstruction structure form that can make full use of the old member of original guardrail again can farthest reduce safety device.
The utility model content
The purpose of this utility model provides a kind of corrugated beam barrier and strengthens reconstruction structure, the crashproof ability of this corrugated beam barrier reinforcement reconstruction structure meets the requirement of guardrail anti-collision level A (Am) level in the current Chinese code of practice, this guard bar structure can make full use of the old member of original guardrail simultaneously, reduces improvement cost.
For realizing above-mentioned target, the utility model adopts following technical scheme: the utility model comprises column, corrugated sheet, stiffening girder, deters member and connecting elements; Column adopts former fence upright to connect height, newly play one of them or the arranged alternate combination of column; Stiffening girder is installed on the top of corrugated sheet, and stiffening girder and corrugated sheet all adopt and deter member and connecting elements is connected with column.
Described stiffening girder is one kind of or several combination of single ripple plate, double wave plate, C shape plate, channel-section steel, rectangular tube, square tube, pipe, elliptical tube.
It is at the top of former fence upright inner sleeve to be installed that described former fence upright connects high, and at the top of the outside of inner sleeve, former fence upright installation increasing outer tube.
When described column specification is φ 114 * 4.5mm steel pipe, lays spacing and be not more than 2m; When described column specification is φ 140 * 4.5mm steel pipe, lays spacing and be not more than 4m.
Described corrugated sheet is double wave plate or three ripple plates, adopts the combination of the one kind of of former guardrail corrugated sheet, new system corrugated sheet or two kinds.
The described member that deters is the one kind of of carriage, obstruction block.
Described connecting elements is the combination of the one kind of of bolt, anchor ear or two kinds.
Guardrail of the present utility model is owing to set up stiffening girder above original guardrail corrugated sheet, and corrugated sheet, stiffening girder all are connected with connecting elements by deterring member with column, during vehicle collision, corrugated sheet and stiffening girder can be stressed jointly, can effectively protect the collision that collision energy is the vehicle of 160kJ, reach the requirement of guardrail A (Am) level anti-collision level in the current specifications.Except that the direct utilization of original guardrail corrugated sheet, former fence upright adopts inner sleeve to realize and being connected of stiffening girder with the height that connects of increasing outer tube, like this, the column and the corrugated sheet of original guardrail are all farthest utilized, and greatly reduce to transform the cost cost of building.
