The present invention is connected montant by stamping connector with upper and lower cross bar, and by fixation kit, the montant at two ends and middle montant are fixed between cross tube and sheer pole, so not only greatly improve the fastness that montant is connected with upper sheer pole, and make on-the-spot installation more convenient, completely realize without electricity and installing.
Description
Technical field
The invention belongs to road traffic facility technical field, be specifically related to a kind of combined road traffic guardrail.
Background technology
Chinese patent literature CN101265694A discloses a kind of jet printing type steel guard rail, comprises column, cross tube, sheer poleAnd montant, cross tube is all connected with column by adapter sleeve with sheer pole, and the connected mode of each montant and upper and lower cross bar has twoKind: a kind of be the mode of welded, and its advantage is that processing is fast, efficiency is high, sound construction, shortcoming be transport, installation notConvenient; Another kind is the mode of plug-in type connecting element, and its advantage is the transport of each accessory, it is more convenient to install, and shortcoming is notFirmly, easily come off.
As the improvement of above-mentioned deficiency, Chinese patent literature CN202108017U discloses a kind of clamp-connected steel guardrail, bagDraw together column, cross tube, sheer pole and montant, cross tube is to be equally all connected with column by adapter sleeve with sheer pole, each perpendicularThe upper end of bar is connected with cross tube by shackle member, and the lower end of montant is connected with sheer pole by male member. Although this guardrail solvesInsecure, hold caducous problem, but when mounted, shackle member and male member need to be weldingly fixed in montant pipe, alsoNeed charged installation, therefore, still exist 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, a sideThis connected mode of face is insecure equally, easily comes off; On the other hand, this connected mode also causes column to be given prominence at cross tubeTop, thereby cause the sensation of numerous and complicated can to passerby and automobile driver. (2) reflective membrane is all attached on montant,Be unfavorable for so on the one hand the visual angle of automobile driver, also increased on the other hand the use amount of reflective membrane, cause costHigh.
Part as above-mentioned deficiency is improved, and Chinese patent literature CN102767146A discloses a kind of streamer guardrail, shouldGuardrail is on the one hand by increase inner column in fence unit, and makes the top of inner column be positioned at the below of cross tube, outside makingAll guardrail heights between column are consistent, thereby the entirety that seems is smooth; On the other hand by reflecting coating is arranged on to top railOn bar, thereby make the unremitting continuous distributed of reflecting coating, be both conducive to the visual angle of automobile driver, reduced again coatingConsumption, reduced production cost. This guardrail be by inner column, cross tube, sheer pole and montant are made single piece fromAddress the above problem, therefore, still have single piece transport, 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 that a kind of montant and upper sheer pole are connected firmly, on-the-spot installationCombined road traffic guardrail easily.
The technical scheme that realizes the object of the invention is: a kind of combined road traffic guardrail, comprise column, cross tube, underCross bar 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 all and instituteState column and connect, 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 equalBe connected with described cross tube, sheer pole by stamping connector; Described stamping connector comprises body, is arranged on described body oneFace is for inserting the internal projection in described montant and being arranged on the outer lug of described body another side, and described body is provided with logicalHole; The lower surface of described cross tube is provided with the punching hole of the outer lug insertion that is suitable for described stamping connector; Described sheer poleUpper surface is provided with the punching hole of the outer lug insertion that is suitable for described stamping connector; Each fence unit has at least three montants logicalCrossing fixation kit is fixedly connected between described cross tube and sheer pole; Described fixation kit comprises a steel pipe, a screw threadExternal member, 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 described inThe upper surface of 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; Described spiral shellThe upper end of line external member is provided with the internal thread adapting with the external screw thread of described steel pipe lower end, the lower end of described thread complete set be provided withThe internal thread that described trip bolt adapts.
In order to make cross tube more firm with being connected of column, the two ends, left and right of described cross tube are all by upright post cap and instituteStating column connects; Described upright post cap comprise below cap seat, above cap and between cap seat and capConnecting portion; The cap seat of described upright post cap is provided with for described upright post cap being fixedly attached to the first spiral shell on described columnHole; The cross section of the cap of described upright post cap is identical with the cross sectional shape of described cross tube and be big or smallly suitable for described cross tube and insert;The connecting portion of described upright post cap is provided with the second screw for described cross tube is fixedly connected with described upright post cap.
Described cross tube is fixedly connected with described upright post cap by a spring leaf; Described spring leaf comprises connecting portion and clampingPortion, the connecting portion of described spring leaf is provided with the 3rd screw; The lower surface two ends place of described cross tube is respectively equipped with draw-in groove; DescribedCross tube inserts in the cap of described upright post cap and by a screw by the second screw and spring on the connecting portion of upright post capThe 3rd screw on the connecting portion of sheet is fixedly connected with, and insert in the draw-in groove of described cross tube the Access Division of spring leaf.
