Abstract
The utility model discloses a back stand combination formula guardrail, by lower part reinforced concrete structure, steel superstructure and connecting elements are constituteed, lower part reinforced concrete structure is guardrail concrete wall, the steel superstructure is by the stand, L type connector plates, the crossbeam is constituteed, stand and L type connector plates form to whole through the welding, the crossbeam passes through bolted connection or welding and stand and forms to whole, the connecting elements comprises the bolt, connector plates and guardrail concrete wall are connected through the bolt. The beneficial effect of the utility model: reasonable in design has changed the mounted position of stand, has increased the guardrail and has met the distance of hitting the identity distance stand, reduces the emergence of the condition that hinders of stumbling behind the vehicle collision effectively, and add connector plates and pass through the bolt and be connected with guardrail concrete wall, the stand was extracted easily when having overcome vehicle collision shortcoming has effectively strengthened barrier propterty, the warning marker that the determining deviation is pasted on the crossbeam can play effects such as the line type is induced, profile sign.
Description
Technical field
The utility model relates to a kind of novel combination type guardrail, specifically, relates to the upright-column combined guardrail in a kind of back.
Background technology
Bridge guardrail is the guardrail be arranged on bridge.Its objective is to prevent errant vehicle from running off outside bridge, have vehicle can not be broken through, under wear, cross bridge and beautify the function of bridge construction.Bridge guardrail many employings combined type guard bar, and steel superstructure column is all arranged on concrete wall by traditional combined type guard bar, can produce following adverse consequences: it is comparatively near that the face of hitting met by column distance guardrail, easily produces resistance of stumbling, and affects guardrail security performance; Column base plate, by meeting the nearer anterior bolt collision rift in the face of hitting by larger pulling force, is easily thrown off from concrete, reduces guardrail integral protection performance.
Therefore, a kind of novel combination type guardrail of design is needed badly, to meet prior art above shortcomings.
Summary of the invention
For the above-mentioned technical problem in correlation technique, the utility model proposes the upright-column combined guardrail in a kind of back.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
The upright-column combined guardrail in a kind of back, be made up of lower rebar concrete structure, steel superstructure and connecting elements, described lower rebar concrete structure is guardrail concrete wall, described steel superstructure is made up of column, L-type junction steel plate, crossbeam, described column and L-type junction steel plate are formed as overall by welding, described crossbeam is bolted or welds becomes overall with column-type, described connecting elements is made up of bolt, and described junction steel plate is connected by bolt with guardrail concrete wall.
Further, the obstruction block be arranged between crossbeam and column is also comprised.
Further, described column is arranged at guardrail reinforced concrete wall back.
Further, described column is the one in H profile steel, rectangle steel, square steel.
Further, on described crossbeam, determining deviation is pasted with alarming sign, containing noctilucence block in described alarming sign.
Further, described obstruction block can arrange and can not arrange according to actual conditions.
The beneficial effects of the utility model: reasonable in design, change the installation site of column, and column is placed in concrete wall back, is connected with bolt by junction steel plate with concrete substrate, can arrange or do not arrange obstruction block between column and crossbeam.Add because column is arranged at body of wall back the distance that the face of hitting met by column and guardrail, can effectively avoid vehicle to stumble the generation of resistance situation; During collision, connecting bolt mainly bears transverse shearing force, can not deviate from from concrete wall, effectively enhances the barrier propterty of guardrail.The alarming sign that on crossbeam, determining deviation is pasted can play the effect of line style induction, profile mark, and the noctilucence block on alarming sign can at night for vehicle provides illumination.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of the utility model protection.
As shown in figures 1 to 6, the upright-column combined guardrail in a kind of back according to the utility model embodiment, by lower rebar concrete structure, steel superstructure and connecting elements composition, described lower rebar concrete structure is guardrail concrete wall 1, described steel superstructure is by column 2, L-type junction steel plate 4, crossbeam 6 forms, described column 2 is H profile steel, rectangle steel, one in square steel, described column 2 is arranged at guardrail reinforced concrete wall 1 back, described column 2 and L-type junction steel plate 4 are formed as overall by welding, described crossbeam 6 is bolted or welds and is formed as overall with column 2, described connecting elements is made up of bolt 3, described junction steel plate 4 is connected by bolt 3 with guardrail concrete wall, on described crossbeam 6, determining deviation is pasted with alarming sign 7, containing noctilucence block 8 in described alarming sign 7.
Actual conditions needed for engineering, the upright-column combined guardrail in back also comprises the obstruction block 5 be arranged between crossbeam 6 and column 2.
When specifically using, when vehicle occurs to clash into, it is nearer that the face of hitting met by column distance guardrail due to conventional guard rail, easy generation is stumbled resistance, affect guardrail security performance, and the column base plate of conventional guard rail is near meeting the anterior bolt collision rift in the face of hitting by larger pulling force, easily throws off from concrete, thus causes barrier propterty low.Column 2 is placed in guardrail concrete wall 1 back by appropriate design by the application, is connected with bolt 3 by L-type junction steel plate 4 with guardrail concrete wall 1, according to construction needs, is also provided with obstruction block 5 between column 2 and crossbeam 6.Because column 2 is arranged at guardrail concrete wall 1 back, add the distance that the face of hitting met by column 2 and guardrail, can effectively avoid vehicle to stumble the generation of resistance situation; When colliding, because bolt 3 mainly bears transverse shearing force, can not deviate from from guardrail concrete wall 1, thus improve the barrier propterty of guardrail, and the alarming sign 7 pasted on the cross beam 6 can play the effects such as line style induction, profile mark, the noctilucence block 8 on alarming sign can at night for vehicle provides illumination.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
