Description
Technical field
The utility model belongs to bridge field, is related to a kind of bridge guardrail.
Background technology
Traditional Bridge guardrail is widely used in bridge side, but the guardrail of prior art is typically limited to only protection to pedestrian.Mesh
Preceding Bridge guardrail is fence type, because reasons in structure causes mechanical strength inadequate, it is impossible to meet the protection to vehicle well
It is required that, easily there is potential safety hazard, inertia is big when being run due to vehicle, and simple stiff safety fence major part is single support
Bar, protection effect is poor, and vehicle easily falls down after breaking support bar from bridge floor, causes the very big casualties.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of bridge guardrail with fine protection effect.
The technical solution of the utility model is as follows：A kind of bridge guardrail, it is characterised in that：In bridge side bank (1) top surface
On be provided with inner side guard assembly and outer guard component along its length, the structure of the two guard assemblies is identical, and simultaneously
Row is set；The inner side guard assembly is made up of column (2) and shoulder guard (3), and its central post (2) is made up of I-steel, should
It is in mounting hole on column lower end insertion bridge side bank (1) top surface and into a single integrated structure by concreting, and column (2)
Upper end is 1-1.5m away from the distance between bridge side bank (1) top surface；The column (2) sets along the length direction on bridge side bank (1)
Put, the spacing between adjacent two root posts, should to be welded with one piece of shoulder guard (3) between 1-2m, and adjacent two root posts (2)
The termination of shoulder guard is welded and fixed with the interlude of column (2), and shoulder guard (3) two plate faces respectively with column (2)
Two sides section be welded and fixed；
Spacing between the inner side guard assembly and outer guard component is 10-30mm, and inner side guard assembly and outer
Connection reinforcing bar (4), the connection reinforcing bar and shoulder guard (3) plate face are densely covered between the corresponding shoulder guard of side guard assembly (3)
Vertically, and connection reinforcing bar (4) two ends be welded and fixed with corresponding shoulder guard (3) respectively.
In said structure, using structure identical inner side guard assembly and outer guard component, this, simplifies knot
Structure, is easy to construction.Also, shoulder guard (3) structural strength is good, the termination of shoulder guard is solid with the interlude welding of column (2)
Determine, and two plate faces of shoulder guard (3) are welded and fixed with two sides section of column (2) respectively, this ensures that overall knot
Structure intensity, prevents vehicle from falling bridge floor after breaking.Column (2) uses I-steel, and column (2) upper end is away from bridge side bank (1) top surface
The distance between be 1-1.5m, so can guarantee that underlying strength again, and inner side guard assembly and outer guard component pass through close
The connection reinforcing bar (4) of cloth is connected, and thus can realize double protection by inner side guard assembly and outer guard component.
Using above technical scheme, the utility model simple structure, it is easy to construction, overall construction intensity is high, can effectively prevent
Only broken by vehicle, so as to avoid vehicle from falling bridge floor after breaking guardrail, so as to overcome the defect of prior art well.
In order to ensure the bonding strength between inner side guard assembly and outer guard component, connection reinforcing bar (4) set
Put density for 30-50 roots/square metre, and connection reinforcing bar (4) a diameter of 40-60mm.
In order to ensure structural strength, the thickness of the shoulder guard (3) is 10-20mm.
Beneficial effect：The utility model simple structure, it is easy to construction, overall construction intensity is high, can effectively prevent by vehicle
Break, so as to avoid vehicle from falling bridge floor after breaking guardrail, so as to overcome the defect of prior art well.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in Figure 1, 2, a kind of bridge guardrail, is provided with inner side protection group along its length on the top surface of bridge side bank 1
Part and outer guard component, the structure of the two guard assemblies is identical, and is arranged side by side.Inner side guard assembly and outside are anti-
Spacing between protecting assembly is 10-30mm, and is preferably 15 or 20mm.
Inner side guard assembly is made up of column 2 and shoulder guard 3, and its central post 2 is made up of I-steel, the shoulder guard 3
Thickness be 10-20mm.It is in mounting hole on the top surface of the lower end of column 2 insertion bridge side bank 1 and integral by concreting
Structure, and the upper end of column 2 is 1-1.5m away from the distance between top surface of bridge side bank 1, and be preferably 1.2m.
Column 2 is set along the length direction of bridge side bank 1, and spacing between adjacent two root posts is 1-2m, and adjacent two
One piece of shoulder guard 3 is welded between root post 2, termination and the interlude of column 2 of the shoulder guard are welded and fixed, and protection
Two plate faces of steel plate 3 are welded and fixed with two sides section of column 2 respectively.Inner side guard assembly and outer guard component are corresponding
