Description
Technical field
The utility model relates to a kind of Traffic Management Facilities, relates in particular to a kind of road surface that is arranged at exit and entrance, in order to the hard elastic body brake flap of caution vehicle deceleration.
Background technology
Existing hard elastic body brake flap is with regard to its structure, and all be spliced the independently of each other brake flap of strip of some block unit, and the both sides of each unit are many is fixed in ground by (also having a two or more) expansion bolt.Therefore, even the formation unit of separate hard elastic body brake flap closely is fixed in ground by expansion bolt, but under the effect of vehicular traffic impulsive contact force repeatedly, to produce reciprocal displacement also unavoidablely and cause becoming flexible, moreover because the position in track of living in relation, displacement and loosening unit often are confined to frequent passing those several of wheel, because local displacement, the vertical bar shape brake flap that is spliced just twists and loses shape; Because loosening, loosening unit is convenient at first cause damage around screw under the wheel forceful action of moment, thereby causes this formation unit and then scrap.
Obviously, such brake flap of prior art has obvious defects on structure Design.In fact also have producer to attempt to take technical measures eliminating above-mentioned defective, as in the position perforation of the vertical central axis of brake flap unit so that install after inserting rectangular steel pipe, in order to pin down mutually in case displacement and loosening; Also have then unit bottom longitudinally position of center line offer groove, and when installing, fix the channel-section steel that an opening makes progress on the road surface of installation place earlier, the brake flap unit is buckled in splices installation on it then.As if the latter is more effective at first view, the channel-section steel that is fixed in the road surface and is stuck in the groove can prevent effectively that more brake flap is subjected to displacement, but turn round and look at this actually and lost that, when the vehicle spreading is on brake flap, the channel-section steel that opening makes progress, its two trough rims form a kind of destructive cutting force for the weak location of brake flap groove, thereby have shortened brake flap effective application life greatly.So in the use of reality, existing product had not both removed to insert long steel pipe arduously, quite do not take time ground yet channel-section steel is installed in advance, especially on the road surface of common arch, must carry out arc process to the steel pipe of channel-section steel or insertion, otherwise ensure the quality of products with regard to being difficult to install proper, in other words, the actual existing structure problem of brake flap but remains unchanged.
Summary of the invention
Purpose of the present invention is exactly that a kind of compact conformation, long service life, hard elastic body brake flap easy for installation are provided in order to overcome the defective that above-mentioned prior art exists.
Purpose of the present invention can be achieved through the following technical solutions: hard elastic body brake flap, this brake flap is made up of polylith hard elastic body unit, the rectangular bulk of this hard elastic body unit, its cross section is a thick middle, the sloping shape structure that both sides are thin, on the inclined-plane of this slope shape structure, be provided with installing hole, it is characterized in that, vertical end face of described hard elastic body unit is provided with the tenon of at least one protrusion, the other end correspondingly is arranged with the mortise that at least one and this tenon structure are complementary, described hard elastic body unit head and the tail joggle and constitute the brake flap of Len req.
Described brake flap two ends respectively are provided with a termination, the end face of this termination and brake flap junction and the shape of cross section of above-mentioned hard elastic body unit are consistent, the end face of described termination is provided with mortise or the tenon that tenon or mortise with above-mentioned hard elastic body unit are complementary, described termination is from its end face and begins sloping shape structure to peripheral attenuate, and the inclined-plane of this slope shape structure is provided with installing hole.
The cross section of described tenon or mortise is polygon, circle or oval.
Described tenon and its end face junction are provided with circular chamfering transition, and the eye of a described mortise mouthful place is provided with circular chamfering and above-mentioned tenon is complementary.
Also be provided with the shrinkage pool that is used to be provided with the caution reflectorized material on the inclined-plane of the sloping shape structure of described each hard elastic body unit.
Compared with prior art, the present invention has the following advantages and effect:
(1) because the formation unit of brake flap has adopted the design of tenon and mortise, so the brake flap that joggle forms has just constituted an integral body, with regard to the formation unit that has not existed and born external force and be subjected to displacement individually isolatedly with regard to structure.Self-evident, the brake flap of tenon joint type is compared with existing technology, obviously the superiority that has immanent structure, thereby under the normal condition of installing and using, just the unit phenomenon become flexible of displacement and causing individually can not take place to constitute, thereby just avoided effectively because of indivedual loosening consequences of damaging of causing, the application life of just having improved brake flap widely.
(2) constitute the design that the unit adopts tenon and mortise, obviously improved the structural strength of brake flap inherence, especially the structure design of this tenon has adopted bionic principle, it is the curved profile line structure that the structure design of this tenon is imitated big usage tree root bulging, therefore compare with traditional straight tenon structure, reasonably increased the physical dimension that the tenon root bears the shearing force position, in order to resist powerful destruction; They are two years old, substitute the outline line structure of the orthoscopic of traditional straight tenon and end face junction with the outline line structure of circular arc, purpose is stress eliminating structure predispose to damage weak joint in the powerful pipeline of moment, thereby the tenon joint type structure that makes the material of homogeneity, equivalent bring up has obtained best drag effect.Just because of the tenon structure simulates remarkable drag structure in the biological phenomena, so this drag structure supported effectively that just this brake flap adopts the design scheme of tenon and mortise, and given the novelty of reasonability, practicality and the technology of tenon joint type structure.
(3) because the formation unit of tenon joint type brake flap self has above-mentioned significant structural advantages, therefore just need not with more existing products such when mounted, must be equipped with the personnel and the instrument of specialty, must carry out steel blanking, radian bending, shaping check etc. according to the physical length of required installation and the radian of road surface arch earlier, employing insertion steel pipe or the fixedly mode of channel-section steel then, be subjected to displacement and become flexible in order to prevent to constitute the unit, finishing operation must use expansion bolt that brake flap is fixed in the road surface; And the brake flap of tenon joint type only need join together into required length with tenon, the eye that constitutes the unit to inserting in the position of installing, and uses expansion bolt to be fixed in the road surface then and gets final product.Two contrast, and the simple and easy degree of its installation of brake flap of tenon joint type just need not superfluous words, therefore, very are convenient to the client and install voluntarily, keep in repair voluntarily, and need not to dispose the professional and use professional tool.
