Abstract
The utility model discloses a saddle type combined guardrail structure which is used for improvement of highway concrete guardrails and combined bridge guardrails, and aims at improving the crashworthiness of the guardrails so as to meet the requirements on the crashworthiness of the guardrails in the current specifications, realize the reuse of a concrete wall body of the original guardrails, reduce the construction difficulty when saving the improvement cost, and shorten the construction time. The saddle type combined guardrail structure comprises an upright, a cross beam, a concrete wall body and connecting members, wherein the upright is in a saddle type, the concrete wall body is the concrete wall body of the original guardrails, and the cross beam, the upright as well as the upright ad the concrete wall body are connected by the connecting member.
Description
Technical field
The utility model relates to highway traffic safety facility field, particularly relates to the transformation of highway concrete guardrail or combined bridge guardrail.
Background technology
Guardrail is the last barrier that highway traffic safety ensures, when the crashworthiness of guardrail does not meet the demands, will go out behind the Vehicular impact guardrail road (bridge) outer or pass through in divide band, cause serious casualties and property loss accident.Therefore, the extrahazardous highway sections of trackside such as key, the particularly highway bridge that rational guardrail is a guarantee driving safety, high embankment, Lin Ya are 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 " expressway traffic safety facilities design and construction technical specification " (JTJ 074-94) in 2006 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 facilities design general specification along the line " be related specifications such as (JTGD80-2006), and its principal character is largely security protection facility anti-collision level to be promoted.Like this; The height and the anti-collision level of the highway barrier of before 2006, building do not meet the current specifications requirement, and particularly the road surface is through the highway of cover overhaul, and its guardrail height is most of not enough; In case after the vehicle collision; With occurring thrusting guardrail easily or crossing guardrail and the serious accident that falls down from the bridge,, tackle it and transform from the angle of safety.
Owing to there was not more economical, the renovation technique of concrete guardrail or combined type guard bar easily in the past; Make the rebuilding construction difficulty very big, need the concrete wall of original guardrail be removed, and then newly-built; So not only cause the increase of improvement cost, also influenced the normal operation of highway.Therefore; Develop and a kind ofly can utilize former guardrail concrete wall to reach the guard bar structure of high-protection level target; Can farthest reduce the improvement cost of concrete guardrail or combined type guard bar, shorten the transformation time, have good economic benefit and social benefit.
The utility model content
The purpose of the utility model provides a kind of saddle shaped combined type guard bar structure; The crashproof ability of this guard bar structure should meet the requirement of guardrail anti-collision level SA (SAm) level in the Chinese code; This guard bar structure should make full use of the concrete wall of original guardrail simultaneously; And construction is simple, thereby reduces improvement cost and shorten the transformation time.
For realizing above-mentioned target, the utility model adopts following technical scheme: the utility model comprises column, crossbeam, concrete wall and connecting elements; Column adopts the saddle shaped column, adopts connecting elements to interconnect between column and crossbeam, column and the concrete wall.
Said saddle shaped column is the combination of the one kind of and saddle shaped base plate of channel-section steel, i iron, H shaped steel, rectangular tube, square tube, pipe, elliptical tube, C shape pipe.
The connecting elements that said saddle shaped column is connected with concrete wall does not need pre-buried, is employed in to install after opening the hole on the concrete wall.
Realize being connected in the side of concrete wall between said saddle shaped column and the concrete wall.
Said crossbeam is the one kind of of rectangular tube, square tube, pipe, elliptical tube, C shape pipe.
The column of the utility model guardrail adopts the saddle shaped column; Its with concrete wall between the connecting elements that is connected adopt the back to install; Promptly on original concrete guardrail body of wall, offer horizontal elongated hole; Then the saddle shaped column is ridden in the concrete wall top, penetrate connecting elements again the saddle column is connected with concrete wall; This fence upright form and connected mode can well be utilized the concrete wall of original guardrail, reach the purpose of practicing thrift cost, make easy construction simultaneously; In addition, saddle shaped pillar construction size can be adjusted according to code requirement and actual protection needs, makes the crashworthiness of the utility model guardrail can reach the requirement of SA (SAm) grade of anti-collision level.
Description of drawings
Fig. 1 is the cross-sectional drawing of the utility model saddle shaped combined type guard bar structure;
Fig. 2 is the cross-sectional drawing of the utility model saddle shaped combined type guard bar structure saddle shaped column;

The specific embodiment
Combine accompanying drawing that the utility model is described further at present.
As shown in Figure 1, the crossbeam 2 of the utility model saddle shaped combined type guard bar structure is installed on the front side, top of saddle shaped column 1 through connecting elements 4, and saddle shaped column 1 rides in the top of concrete wall 3, and connects fixing through connecting elements 5.
Like Fig. 2, shown in Figure 3, saddle shaped column 1 is made up of shaft 6 and saddle shaped base plate 7, and connecting hole 8 is offered in the side of saddle shaped base plate, is used for the connection of connecting elements 5.
As shown in Figure 4, adopt the mode of back perforate to offer elongated connecting hole 9 on the concrete wall 3, be used for the connection of connecting elements 5.
