Description

Compound Bridge guardrail

Technical field

The utility model relates to technical field of bridge construction more particularly to a kind of compound Bridge guardrails.

Background technique

Bridge guardrail is a kind of safety protection facility on bridge, its reason metallic support and steel manage and protect column composition, often Bridge guardrail is fence type structure, is usually connected and composed by some square steel or steel pipe.It is lacked existing for Bridge guardrail at present Point is that structural strength is poor, is easily damaged under extreme case by the shock of vehicle, if surrounding is river, is fallen after Vehicular impact Entering will be hardly imaginable in river.

Utility model content

The main purpose of the utility model provides a kind of compound Bridge guardrail aiming at the above problem.

In order to achieve the above object, the utility model adopts the following technical solutions: a kind of compound Bridge guardrail, feature exist In: including concrete bed, preceding bumper bracket, rear support frame, attachment base, horizontal attachment beam and oblique attachment beam；The preceding bumper bracket and The structure of rear support frame is identical, is made of respectively crossbeam, vertical beam and cross pipe beam, and the vertical beam is vertically fixed between crossbeam, The bottom of crossbeam is embedded in the concrete bed, and the cross pipe beam is connect by attachment base with the crossbeam and vertical beam, institute Linked together between bumper bracket and rear support frame by the horizontal attachment beam and oblique attachment beam before stating, the cross pipe beam it is interior Portion is embedded with the wirerope to interconnect, and wirerope lower part is embedded in inside concrete bed.

Preferably, the lower part of the concrete bed is embedded with stay hook, is fixed together and passes through mixed with bridge steel structure Solidifying soil pours.

Preferably, the horizontal attachment beam and oblique attachment beam are also embedded to the wirerope being sequentially connected end to end.

Preferably, the preceding bumper bracket and rear support frame top are welded with fixing seat, and decoration is welded in the fixing seat Handrail.

Preferably, the preceding bumper bracket uses Q235 common carbon structural steel, and rear support frame uses Q510 structural carbon steel.

The beneficial effects of the utility model are: compared with the existing technology, present apparatus intensity is high, and rigidity is big, corrosion-resistant strong, energy Play the role of Double-protection, and grip performance is good, be not easy to damage because of strong impact force, and there is certain buffering Power can effectively reduce damage situations caused by when automobile etc. is out of control to rush at guardrail.Traditional single-spar construction is changed to by the present apparatus Two kinds of mixed structures of preceding bumper bracket and rear support frame, and wirerope is provided with when traffic accident occurs in cross pipe beam, it is preceding slow The effect of buffering Vehicular impact is erected in punching, and rear support frame structure is relatively more firm to be able to bear biggish shock, internal steel wire Rope is equivalent to a fishing net, and the preceding bumper bracket wirerope that deforms catches vehicle and prevents it from falling in water after Vehicular impact.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the side view of the utility model.

Specific embodiment

With reference to the accompanying drawing and specific embodiment of the present utility model is described in detail in preferred embodiment.As shown in Figure 1, one Kind compound Bridge guardrail, including concrete bed 1, preceding bumper bracket 2, rear support frame 3, attachment base 4, horizontal attachment beam 5 and tiltedly connect Connect beam 6；The preceding bumper bracket is identical with the structure of rear support frame, is made of respectively crossbeam 7, vertical beam 8 and cross pipe beam 9, described Preceding bumper bracket uses Q235 common carbon structural steel, and rear support frame uses Q510 structural carbon steel, Q235 common carbon structural steel Certain buffer function can be played, and Q510 carbon structure hardness of steel is harder, stretching-resisting bending-resisting ability is relatively good, so playing The effect of support, the vertical beam are vertically fixed between crossbeam, and vertical beam is more, together with beam welding, the cross of lowest part The bottom of beam is embedded in the concrete bed, and the cross pipe beam is connect by attachment base with the crossbeam and vertical beam, is passed through The mode of welding is fixed with attachment base, is connected between the preceding bumper bracket and rear support frame by the horizontal attachment beam and oblique attachment beam It is connected together, the inside of the cross pipe beam is embedded with the wirerope 10 to interconnect, and wirerope lower part is embedded in concrete Chassis interior.The horizontal attachment beam and oblique attachment beam are also embedded to the wirerope being sequentially connected end to end.Wirerope is in cross pipe beam, cross The setting intersected in attachment beam and oblique attachment beam, node is all by being welded and fixed, and such guardrail just forms one and throws the net, and works as generation Vehicle can be wrapped when shock, it is effectively prevent to fall in water.

Working principle: two kinds of mixed structures of bumper bracket and rear support frame before traditional single-spar construction is changed to by the present apparatus, And wirerope is provided with when traffic accident occurs in cross pipe beam, preceding bumper bracket plays the role of buffering Vehicular impact, rear to prop up Strut configuration is relatively firm to be able to bear biggish shock, and internal wirerope is equivalent to a fishing net, preceding slow after Vehicular impact The frame wirerope that deforms is rushed to catch vehicle and prevent it from falling in water.

In order to further increase the stability of the present apparatus, the lower part of the concrete bed is embedded with stay hook, with bridge steel Structure is fixed together and passes through concreting.

In order to play decoration function, the preceding bumper bracket and rear support frame top are welded with fixing seat 11, the fixing seat On be welded with decoration handrail 12.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching also should be regarded as the protection scope of the utility model.
