Below the specific embodiment each accompanying drawing is briefly explained
The title of each member that this road guard adopts: column (1), rectangle steel crossbeam (2) channel-section steel crossbeam (3), last beam and face (4) (5) is beam and face (6) down, carriage (7) (8), column cap (9), girder steel splicing sleeve (10) girder steel connects steel plate (11), steel, desk connector (12), rounded nose bolt (13), snap bolt groove (14).Referring to Fig. 2,3,4,5,6.
As shown in Figure 2, the cross-sectional form of this road guard is two beam structures.Upper beam is rectangular steel pipe (2), and crossbeam front and end face are lined with panel (4) (5); Lower transverse beam is channel-section steel (3), and the front is lined with panel (6).The top rail front surface slightly protrudes in lower transverse beam.Top rail has adopted the crossbeam of closed section, has improved the structural strength of guardrail greatly, makes guardrail have stronger protective capacities.In vehicle and rail collision process, have certain thickness panel and can play cushioning effect, the higher continuous steel crossbeam of rigidity can prevent effectively that vehicle from going out road.Lower transverse beam has adopted the simple channel-section steel of structure as agent structure, and the surface is lined with thicker panel, and the auxiliary energy that absorbs is adjusted direction of traffic in the collision process.
Top rail slightly protrudes in lower transverse beam and mainly contains following advantage.
(1) reduces vehicle owing to turn over the possibility of the guardrail that jumps behind wheel and road kerb collision the causing jumping car.
(2) when vehicle and rail collision, earlier with put the beams in place collision again with the underbeam collision, thereby prolonged the time of collision, the impact force when reducing vehicle collision is to driver and crew's infringement.
(3) prevent vehicle in collision process, under crossbeam, get out guardrail, prevent that simultaneously wheel and crossbeam and column extension once was stuck.
(4) the slight accident top rail of only can swiping can not cause damage to lower transverse beam, only need change upper beam during replacing, thereby reduce maintenance cost.
Scheme neutral cap can adopt rubber column cap through anti-aging processing be coated with the approaching coating of guardrail cross beams panel color, also can adopt traditional steel column cap, use inferior optical coating to soak in zinc-plated anticorrosion back and mould processing.Use inferior optical coating that guardrail is better merged mutually with scenery on every side, can avoid facility reflected sunlight, light to cause that the driver dazzles the eyes simultaneously, improve driver comfort.
As Fig. 3, shown in Figure 6, this road guard column (1) is connected by carriage (7) (8) with girder steel (2) (3).Column links to each other by a connecting bolt with carriage, and carriage links to each other by two connecting bolts with girder steel, and promptly girder steel links to each other by three connecting bolts with column.Can see that from carriage drawing 6 column connecting bolt hole is a horizontal slotted hole, girder steel and carriage connecting hole also are slotted hole in addition, and the adjusting of guardrail cross beams position when these three slotted holes make things convenient for the guardrail construction is convenient to install.(7) three connecting bolt holes of bracket become isosceles triangle to arrange as shown in Figure 6 simultaneously, and this design can effectively improve the intensity of carriage when guardrail is received collision, prevents the carriage fracture, thereby increase the bonding strength of guardrail cross beams and column.The bolt and nut of Fig. 3 central post is hidden in the carriage, and the bolt of carriage is hidden in the undercut of front panel, by this kind method, can solve the antitheft problem of guardrail junction.Certainly also can use anti-theft bolt to strengthen anti-theft effect.
As shown in Figure 4, connect by connector between the road guard girder steel of the present invention.Top rectangle crossbeam links to each other by a rectangle sleeve pipe (10), and the splicing sleeve undersized is in girder steel.The girder steel junction is similarly slotted hole, and an end is horizontal slotted hole, the error of fence upright horizontal spacing when constructing in order to adjust, and the other end is vertical hole, with the skew of adjustment guardrail cross beams level height, and the variation that adapts to the road longitudinal gradient.The caliber of caliber, particularly fore-and-aft direction by changing splicing sleeve (10) can make guardrail adapt to bend than long radius substantially, is arranged at the bend of small radii as guardrail, and the bending of crossbeam connector can be had a certain degree re-uses.The bottom channel-section steel uses steel plate to connect, and the hole of girder steel junction is identical with top rail.Connecting bolt is hidden in the undercut of front panel equally, and sleeve pipe has limited the installation of guardrail must carry out from single direction, is difficult to the crossbeam in the section of taking off under the situation that crossbeam does not have to damage, this to antitheft also be very favorable.
As shown in Figure 5, this road guard steel, panel construction connect.The top rail panel is spliced by header board (4) and top board (5), and splicing part has used tenon riveting structure, and top panel inserts in the tongue-and-groove of front panel, and the back side is reserved tongue-and-groove and is used for and being connected of steel, desk connector (12).Front panel links to each other with girder steel (2) by round end connecting bolt (13), and top board relies on tenon and connector (12) to be fixed in rectangle crossbeam top, and connecting bolt is not used in inside.Following beam and face links to each other with channel-section steel (3) by snap bolt (13).The snap bolt that panel is connected with girder steel passes the connecting hole (14) of particular design and being connected of steel, desk connector (12) realization steel and panel construction, and the snap bolt end face does not exceed panel surface.
