Abstract
The utility model discloses a kind of tiltable combined steel railing, belong to railings for rail/road crossing traffic field.This tiltable combined steel railing comprises vertical tube, transverse tube, column, is provided with L-type junction plate between vertical tube and transverse tube, and junction plate is welded on transverse tube and forms the first revolute pair, and junction plate another side is welded in vertical tube and forms the second revolute pair.The utility model is adopted to realize the installation of fence on ground, large angle of inclination.
Description
Technical field
The utility model relates to railings for rail/road crossing traffic field, specifically a kind of tiltable combined steel railing.
Background technology
Existing most combined steel rail structure is made up of pillar parts, strut rail parts and connection fittings.Its connected mode is: the transverse tube on strut rail parts and vertical tube adopt welding manner to be integrally formed, and strut rail parts and pillar parts then adopt and be welded on standing finish on column and screw assembly connects into entirety.Existing this combined steel rail structure, because vertical tube all can not produce rotation relative to transverse tube, transverse tube parts relative to both pillar partses, thus can only lean on the fit-up gap of railing and elastic deformation tilt a little some angles adapt to light grade road install.And be adopt field fabrication to install for the gradient road one being greater than 3 °, this mode efficiency is low, cost is high, of poor quality; Two is adopt notch cuttype, and this mode is suitable for linearly gradient road, otherwise both can increase stem height and balustrade length kind quantity, and the railing after installing can be made again linear ugly.
If the patent No. is that CN200720107233.7 (publication number: CN201011189Y) discloses a kind of tiltable railing, mainly adopt on transverse tube and open longitudinal hole, standpipe is inserted corresponding hole, with rivet interlacement transverse tube and standpipe, realize the possibility of the relative displacement between transverse tube and standpipe with the gap between standpipe tube wall and jack.
This utility model is created also exists following problem: the space between each connector of integral inclined angle dependence of railing is to realize relative displacement, and tiltable angle is little, and syndeton is firm not.Therefore, research and develop and a kind ofly the modular railing of wide-angle tilt can just seem particularly necessary.
Utility model content
The utility model aims to provide a kind of tiltable combined steel railing, and the tiltable angle of the relative transverse tube of vertical tube is increased, to realize the installation of fence on ground, large angle of inclination.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of tiltable combined steel railing, comprise vertical tube, transverse tube, column, it is characterized in that: between vertical tube and transverse tube, be provided with L-type junction plate, junction plate is while be connected on transverse tube and form the first revolute pair, junction plate another side is connected in vertical tube and forms the second revolute pair, and the first revolute pair and the second revolute pair coordinate formation articulated structure.
Further, both sides, junction plate corner have breach.
Further, described junction plate port is rounded down or oblique angle.
Further, corresponding junction plate position, vertical tube two ends has plug welding hole.
The beneficial effects of the utility model are:
One, be provided with L-type junction plate between vertical tube and transverse tube, junction plate is welded on transverse tube and forms the first revolute pair, and junction plate another side is welded in vertical tube and forms the second revolute pair.By the cooperation of two revolute pairs, realize the effect that can produce relative rotation each other between vertical tube and transverse tube, increase relative angular displacement between transverse tube and vertical tube, high inclination-angle gradient ground also can be installed and used.
Two, play same hinged effect, but compared with hinged more easily, cost is cheaper.
Three, at both sides, the corner gap of junction plate, making junction plate rigidity around the corner minimum, guaranteeing that the junction plate of L-type on the corner deformation occurs, and does not affect the function of revolute pair when being out of shape.When junction plate generation deformation, two revolute pairs are connected firmly without distortion, make overall structure more firm.
Four, a port of junction plate is rounded down or oblique angle, when installing junction plate, conveniently junction plate is inserted vertical tube.
Five, corresponding junction plate position, vertical tube two ends has plug welding hole, and plug welding hole facilitates welding of vertical tube and L shape junction plate.

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
As shown in Figures 1 to 5, a kind of tiltable combined steel railing, comprise vertical tube 2, transverse tube 1, column, it is characterized in that: between vertical tube 2 and transverse tube 1, be provided with L-type junction plate 9, junction plate 9 is while be welded on transverse tube 1 and form the first revolute pair 8, and junction plate 9 another side is welded in vertical tube 2 and forms the second revolute pair 3.First revolute pair 8 and the second revolute pair 3 coordinate formation articulated structure.Both sides, junction plate corner 5 place have breach 6.Described junction plate 9 one ports are rounded down 7 or oblique angle.Corresponding junction plate 9 position, vertical tube 2 two ends has plug welding hole 4.
When mounted, first L shape junction plate 9 is welded together by vertical tube 2 spacing and transverse tube 1, make it the half becoming revolute pair.Again by the plug welding hole 4 that corresponding junction plate 9 position of vertical tube is opened, vertical tube 2 and L shape junction plate 9 another side are welded together second half that make it to become revolute pair.
When road surface is the level of state, the installation base surface of two root posts is contour, the transverse tube 1 after now installing and vertical tube 2 without the need to rotating, now vertical tube 2 and the rectangular state of transverse tube 1.
When road surface is slope state, as shown in Figure 1, the installation base surface of two root posts is not contour.The breach 6 that second auxiliary connection 3 prolongs junction plate produces deformation bending, and as shown in Figure 3, relatively rotate between transverse tube 1 and vertical tube 2, form a rhombus state, ramp angles is larger, and vertical tube angle of inclination is larger, the maximum tiltable miter angle of railing.Employing the utility model is with low cost, effectively realizes the installation of fence on ground, large angle of inclination.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
