Abstract
The utility model discloses a bridge side safety railing. The bridge side safety railing comprises a handrail, wherein upright posts are arranged in the length direction of the handrail, a fixed seat is arranged at the bottoms of the upright posts, the cross section of the fixed seat in the radial direction takes the shape of an isosceles trapezoid, and the side with a relatively big area of the fixed seat is fixed to the ground; the cross section of the handrail in the width direction is waved, the upright posts are arc-shaped in the length direction, the part of the arc-shaped upright posts, bending toward the outer side of a bridge, are connected with the fixed seat through support shafts, and a noctilucent layer is arranged on the surface of each upright post; the adjacent upright posts are connected through reinforcing bars parallel to the handrail, and raised lines are arranged on the surfaces of the reinforcing bars at intervals in the length direction. The bridge side safety railing reduces the wind and rain impacting force on the bridge floor and guy cables, prolongs the service life of the bridge and reduces the clash strength of cars due to the buffering function, so that damage of the cars and the railing is reduced, and accordingly, the maintenance cost is lowered.
Description
Technical field
The utility model relates to building field, especially relates to a kind of bridge side life rail.
Background technology
Bridge length is easily subject to the impact of wind and rain and reduction of service life compared with long bridge, in order to reduce this phenomenon, the mode adopting is at present, in the outside of bridge, induced draft plate is installed, this induced draft plate is expensive, difficulty is installed, and easily damages inconvenient maintenance, affect the attractive in appearance of bridge, also inconvenient outlook on children enjoys scenery simultaneously; The column of bridge is cylinder or rectangle, and crashproof weak effect is installed unstablely, easily comes off; In the time having Vehicular impact railing, railing is easily severed, light car and railing are all subject to very large damage, and maintenance cost is high, heavy cause security incident, threatens occupant's life security.
Utility model content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of crashproof effective, also has the bridge side security guardrail of air inducing effect.
To achieve these goals, the utility model is by the following technical solutions: a kind of bridge side security guardrail, comprise handrail, be interval with column along handrail length direction, described column bottom is provided with holder, holder cross section is radially isosceles trapezoid, and the one side that holder area is larger is fixed with ground; The cross section undulate of described handrail broad ways, described column is curved along its length, and arcuate pillar stand is connected with holder by back shaft to the part of bridge outside curve, and described column surface is provided with noctilucence layer; Between described adjacent upright posts, be connected by the reinforcing strip be arrangeding in parallel with handrail, described reinforcing strip surface is interval with raised line along its length.
As preferably, described reinforcing strip is at least 2; Described column surface is provided with the first protuberance that spirals along its length and rise; Described back shaft surface is provided with the second protuberance that spirals along its length and rise.
In sum, the utlity model has following advantage: described bridge side security guardrail has reduced the dynamics that wind and rain impacts bridge floor and drag-line, extended the application life of bridge, the effect of band buffering, reduce the dynamics of Vehicular impact, and then reduced the damage of vehicle and railing, reduced maintenance cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out to clear, complete description.
As shown in Figure 1, a kind of bridge side security guardrail, comprise handrail 1, be interval with some columns 2 along handrail 1 length direction, column 2 bottoms are provided with the holder 3 be arrangeding in parallel with handrail, and this holder 3 cross section is radially isosceles trapezoid, and the one side that holder 3 areas are larger is fixed with ground, it is stable, firm that the holder of this shape is installed, the good fixing effect of column; The cross section undulate of described handrail 1 broad ways, described column 2 is curved along its length, the handrail of this shape has played good guiding function to oncoming wind and rain, reduce the dynamics that wind and rain impacts bridge floor and drag-line, extended the application life of bridge, and the column of arc also plays the effect of buffering in the time of Vehicular impact, reduced the dynamics of Vehicular impact, and then reduced the damage of vehicle and railing, further reduce the maintenance cost of vehicle and railing; Described arcuate pillar stand is connected with holder 3 by back shaft 4 to the part of bridge outside curve, is provided with back shaft, and the column of arc has been played to good reinforcement effect, further strengthens the effect of its impact resistance, and structure is more stable, safe; Described column 2 surfaces are provided with noctilucence layer, and this noctilucence layer is set, and in the situation that night, car light was opened, can clearly see railing, have reduced the probability that accident occurs, and have further improved safety; Described adjacent upright posts 2 connects by the reinforcing strip parallel with handrail 15, and described reinforcing strip 5 surfaces are interval with raised line along its length, reinforcing strip is set and is connected adjacent column, the power of shock is assigned on connected column, the effect of strengthening its crashworthiness, structure is more firm, safer; Described railing low cost of manufacture, installs easily, and not fragile, easy to maintenance, good looking appearance also can not block the sight line that outlook on children enjoys scenery simultaneously.
Concrete, in order further to strengthen its crashworthiness effect, described reinforcing strip 5 is 2, and certainly in other embodiments, reinforcing strip can be also more than 2, and its effect reaching is approximate; Described column 2 surfaces are provided with the first protuberance that spirals along its length and rise; Described back shaft (4) surface is provided with the second protuberance that spirals along its length and rise; This first protuberance and the second protuberance are set, can uniform distribution be applied to column and make the power on axle, make its intensity stronger, be difficult for being severed simultaneously, safety is higher.
Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all should belong to the scope of the utility model protection.
