Description
Technical field
The invention belongs to road traffic facility technical field, be specifically related to a kind of combined type guard bar.
Background technology
Chinese patent literature CN101265694A discloses a kind of jet printing type steel guard rail, comprise column, cross tube, sheer pole and montant, cross tube is all connected with column by adapter sleeve with sheer pole, the connected mode of each montant and upper and lower cross bar has two kinds: a kind of mode for welded, its advantage is that processing is fast, efficiency is high, sound construction, and shortcoming is that transportation, installation are inconvenient; Another kind is the mode of plug-in type connecting element, and its advantage is the transportation of each accessory, it is more convenient to install, and shortcoming is insecure, easily comes off.
Improvement as above-mentioned deficiency, Chinese patent literature CN202108017U discloses a kind of clamp-connected steel guardrail, comprise column, cross tube, sheer pole and montant, cross tube is to be equally all connected with column by adapter sleeve with sheer pole, the upper end of each montant is connected with cross tube by shackle member, and the lower end of montant is connected with sheer pole by male member.Although that this guardrail has solved is insecure, hold caducous problem, when mounted, shackle member and male member need to be weldingly fixed in montant pipe, also needs charged installation, therefore, still exists inconvenient shortcoming is installed.
All there are following 2 deficiencies in above-mentioned two kinds of guardrails: (1) upper and lower cross bar is connected with column by adapter sleeve, and this connected mode is insecure equally on the one hand, easily comes off; On the other hand, this connected mode also causes column to be given prominence to above cross tube, thereby causes the sensation of numerous and complicated can to passerby and automobile driver.(2) reflective membrane is all attached on montant, is unfavorable for so on the one hand the visual angle of automobile driver, has also increased on the other hand the use amount of reflective membrane, causes cost higher.
Part as above-mentioned deficiency is improved, Chinese patent literature CN102767146A discloses a kind of streamer guardrail, this guardrail on the one hand by increasing inner column in fence unit, and the top that makes inner column is positioned at the below of cross tube, make all guardrail heights between outer column consistent, thereby seem whole smooth; On the other hand by reflecting coating is arranged on cross tube, thereby make the unremitting continuous distributed of reflecting coating, be both conducive to the visual angle of automobile driver, reduced again the consumption of coating, reduced cost of production.Thereby this guardrail addresses the above problem by inner column, cross tube, sheer pole and montant are made to single piece, therefore, still there is single piece transportation, inconvenient shortcoming is installed.
Above-mentioned three kinds of guardrails are steel guard rail, get rusty easily like this.
Summary of the invention
The object of the invention is to address the above problem, provide a kind of and be not only connected firmly but also on-the-spot combined type guard bar easy for installation.
The technical scheme that realizes the object of the invention is: a kind of combined type guard bar, comprises column, cross tube, sheer pole and montant; The two ends, left and right of described cross tube are all connected with described column, and the two ends, left and right of described sheer pole are all connected with described column, and the two ends up and down of described montant are connected with described cross tube, sheer pole respectively; The two ends up and down of described montant are all connected with described cross tube, sheer pole by stamping connector; Described stamping connector comprises body, is arranged on the outer lug of described body one side for inserting the internal projection in described montant and being arranged on described body another side, and described body is provided with through hole; The soffit of described cross tube is provided with the punching hole of the outer lug insertion that is suitable for described stamping connector; The upper surface of described sheer pole is provided with the punching hole of the outer lug insertion that is suitable for described stamping connector.
In order to make montant further firm with being connected of upper sheer pole, guardrail of the present invention also comprises for described montant is fixedly connected on to the fixation kit between described cross tube and sheer pole; Described fixation kit comprises a steel pipe, a thread complete set, a square external member and a trip bolt; The upper end of described steel pipe and described square external member are welded and fixed, and the upper surface of described square external member is suitable for inserting in the punching hole of described cross tube; The lower end of described steel pipe is provided with external screw thread; The upper end of described thread complete set is provided with the internal thread that the external screw thread with described steel pipe lower end adapts, and the lower end of described thread complete set is provided with the internal thread adapting with described trip bolt.
