Abstract
The utility model relates to an intelligent anti-collision protective guard bar, belonging to the technical field of highway bridge safeguard, the intelligent anti-collision protective guard bar comprises a built-in steel plate with a built-in bolt, a supporting rack with an installing base plate, palisades and handrails which are fixedly connected to the supporting rack. A through hole is opened on the installing base plate of the supporting rack, and the supporting rack is sheathed on the built-in bolt by the through hole on the installing base plate and is installed on the built-in steel plate. The utility model is characterized in that the through hole on the installing base plate of the supporting rack is an inclined strip through hole, and a smooth plate with tiny coefficient of friction is clamped between the installing base plate of the supporting rack and the built-in steel plate. The intelligent anti-collision protective guard bar has the advantages of having the action of rapidly alleviating and digesting the collision force of an automobile while finishing usually guarding function, The intelligent anti-collision protective guard bar has convenient installation and easy reloading, and can replace the anti-collision protective guard bar of the existing rigid connection structure.
Description
Technical field
The utility model relates to a kind of anticollision barrier that is installed on the bridge.Belong to highway protective equipment technical field.
Background technology
Sweep away bridge when preventing that automobile from meeting accident, usually anticollision barrier will be installed on bridge.The anticollision barrier of installing on the bridge mostly is made of the pre-embedded steel slab that has pre-embedded bolt, the bracing frame that has an installation base plate and fence and the handrail that is fixed on the bracing frame at present, have the manhole corresponding with pre-embedded bolt on the installation base plate of bracing frame, bracing frame is enclosed within on the pre-embedded bolt by the manhole on the installation base plate and is installed on the pre-embedded steel slab.The shortcoming of this anticollision barrier be between bracing frame and the pre-embedded steel slab for being rigidly connected, self does not have any cushioning effect, when automobile meet accident knock after, the impact force of generation is very big, thereby the consequence that causes is very serious.
The utility model content
The purpose of this utility model is the above-mentioned shortcoming that overcomes existing anticollision barrier, and a kind of intelligent anticollision barrier with buffering effect is provided.
This intelligent anticollision barrier, comprise the pre-embedded steel slab that has pre-embedded bolt, have one and the bracing frame of base plate is installed and is fixed in fence and handrail on the bracing frame, on the installation base plate of bracing frame, have through hole, bracing frame is enclosed within by the through hole on the installation base plate and is installed on the pre-embedded steel slab on the pre-embedded bolt, feature of the present utility model is that the through hole that described bracing frame is installed on the base plate is oblique strip through-hole, installs between base plate and the pre-embedded steel slab at described bracing frame and is folded with a smooth plate that friction factor is very little.The tail end that pre-embedded bolt leans against oblique strip through-hole during use is installed in bracing frame on the pre-embedded steel slab, and the section of vacating of oblique strip through-hole is sailed the direction of coming towards automobile, and promptly automobile hits the direction of guardrail.When automobile meets accident when knocking guardrail, guardrail then can drive bracing frame together along the smooth plate surface with respect to the direction of advance slippage along automobile of pre-embedded steel slab, the former section of the vacating end of the oblique strip through-hole on the base plate is installed by touching up to bracing frame in pre-embedded bolt.This slipping has played good cushioning effect, and the impact of automobile is extenuated by rapid digestion, finishes the bracing frame and the fence that still remain fixed on the pre-embedded steel slab after the slippage and also continues to play a part to stop automobile.
Compared with the aforementioned existing similar products, the utility model has the advantages that the effect that also has rapid alleviation digestion automobile impact force when blocking protective function usually finishing, thereby can reduce the harm of automobile collision accident greatly.And install comparatively easyly, change the outfit easily.The anticollision barrier of the alternative existing structure that is rigidly connected uses.
Content of the present utility model is done further explanation with the following Examples.

The specific embodiment
Shown in Fig. 1～3, the formation of this intelligent anticollision barrier comprises the pre-embedded steel slab 6 that has pre-embedded bolt 7, have one installs the bracing frame 5 of base plate 4 and is fixed in fence 2 and handrail 1 on the bracing frame 5, on the installation base plate 4 of bracing frame, have oblique strip through-hole 8, bracing frame 5 is enclosed within and is installed on the pre-embedded bolt 7 on the pre-embedded steel slab 6 by oblique strip through-hole 8 on the base plate is installed, more than each parts all can adopt the form of structure of existing various anticollision barriers.Between bracing frame installation base plate 4 and pre-embedded steel slab 6, be folded with a smooth plate 9 that friction factor is very little, referring to Fig. 4.Smooth plate 9 can be the tetrafluoro plate that adopts the tetrafluoro material to make.Also can adopt the very little smooth plate of skin-friction coefficient of other material.Fig. 5 is the station schematic diagram that takes place between slippage rear support stand installation base plate and pre-embedded bolt.Install base plate and under the impact effect of automobile slippage takes place this moment, the former section of the vacating end of the oblique strip through-hole on the base plate is installed by touching in pre-embedded bolt up to bracing frame.
Claims (2)
1, intelligent anticollision barrier, comprise the pre-embedded steel slab that has pre-embedded bolt, have one and the bracing frame of base plate is installed and is fixed in fence and handrail on the bracing frame, on the installation base plate of bracing frame, have through hole, bracing frame is enclosed within by the through hole on the installation base plate and is installed on the pre-embedded steel slab on the pre-embedded bolt, it is characterized in that the through hole that described bracing frame is installed on the base plate is oblique strip through-hole, install between base plate and the pre-embedded steel slab at described bracing frame and be folded with a smooth plate that friction factor is very little.
2, intelligent anticollision barrier as claimed in claim 1 is characterized in that described smooth plate is the tetrafluoro slide plate.
