Detailed description of the invention
Referring to Fig. 1, the utility model speedway monophasic waveform joist steel guardrail is described in detail.
The utility model speedway monophasic waveform joist steel guardrail can be used for highways and urban roads engineering, is particularly suitable for safety and cushions the higher speedway of functional requirement and city expressway engineering construction.Speedway monophasic waveform joist steel guardrail is formed by the multiple guardrail subelement assembly connections arranged along road order.Be illustrated in figure 1 a guardrail subelement of highway, be respectively to left side on the right side of Fig. 1: column 7, be assemblied in the obstruction block 3 of column 7 sidewall, be assemblied in scab 2, the monophasic waveform joist steel crossbeam 1 be assemblied in scab 2 of obstruction block column 7 side dorsad.Concrete structure is:
Each column 7 passive is the design of Large space weak separation with trackside along direction of traffic.Column 7 is round steel pipe column, and for the guardrail of A level 160kj, rigidity can be adopted to be not more than the Q235 round steel pipe column of diameter 114mm, thickness 4mm, and the spacing between adjacent upright posts 7 is not less than 4 meters.Cap 6 is equipped with, to make the inner dustproof and waterproof of column 7 of steel pipe type on the top of column.
The sidewall of column 7 is provided with described obstruction block 3, obstruction block 3 is in hollow tubular, it comprises the vertical side 31 being installed on column 7 sidewall, by bolt 4, this vertical side 31 of obstruction block 3 is assemblied on the sidewall of column 7, in order to install firmly, bolt 4 can adopt stay bolt, and the relative sidewall penetrating column 7 is installed.The up and down both sides 32,33 adjacent with vertical side 31 of obstruction block 3 be arranged in parallel towards oblique upper, and the angle that namely vertically side and top 32 are formed is that obtuse angle is arranged.The another side relative with vertical side 31 of obstruction block 3, immediate shipment cobordant 34 has department of assembly, and the shape of department of assembly can be set to match with monophasic waveform joist steel crossbeam 1 shape that will assemble.Wherein, vertical side 31 shape of obstruction block can be tabular, i.e. setting tangent with column sidewall, and so vertical side 31 manufactures easily shaping, and cost is low, cost-saving.In addition, if do not consider the problem of cost, the described vertical side edge shape of obstruction block also can be coincide with column sidewall shape and be arranged, and such obstruction block can coincide with column sidewall and assemble, assembling firm stable.
Because the up and down both sides 32,33 adjacent with vertical side 31 of obstruction block 3 be arranged in parallel towards oblique upper, collided at guardrail, when obstruction block 3 is subject to the pressure towards column 7, described upper and lower both sides are due to stressed, upper and lower both sides 32,33 clockwise direction in Fig. 1 is rotated, thus improve the spatial altitude of crossbeam in collision process be arranged on obstruction block 3, like this, can effectively avoid cart roll crossbeam and cross.This deformation process of obstruction block 3, dissolves the impact force part towards column 7 as strength upward, thus also reduces anti-force, namely improve buffer effect.
Department of assembly on the assembling limit 34 of obstruction block 3 is provided with scab 2, adopts steel plate.Scab 2 for assembling monophasic waveform joist steel crossbeam 1, and connects the monophasic waveform joist steel crossbeam of adjacent barrier plank unit.Wherein, by bolt 5, described monophasic waveform joist steel crossbeam 1, scab 2 and obstruction block 3 are assembled.The design quantity of bolt 5 requires to determine according to guardrail anti-collision level.When connecting the monophasic waveform joist steel crossbeam of adjacent barrier plank unit, adjacent monophasic waveform joist steel crossbeam joint can adopt the male and female round plug mode that disappears to splice and be assembled on scab 2.The impact resistance power of monophasic waveform joist steel crossbeam 1 can be strengthened by scab 2.
Wherein, described male and female disappear round plug splicing, refer to the overlapping position stacked at adjacent monophasic waveform joist steel crossbeam 1, be fitted in another monophasic waveform joist steel crossbeam arcuation place after being removed by the part energy-gathering ring 12 of monophasic waveform beam crossbeam 1 upper and lower sides being held down placement, and be assembled on scab 2 by the bolt hole pre-set.
In addition, according to the requirement of guardrail anti-collision level, on described obstruction block 3, can arrange on assembling limit and arrange shape, measure-alike monophasic waveform joist steel crossbeam more, form the multilayer crossbeam of vertical direction.Wherein present embodiment illustrates the embodiment being assembled with two row's crossbeams.When assembling two row or more crossbeam, the rigidity of the monophasic waveform joist steel crossbeam that lower row is arranged is not more than the rigidity of the monophasic waveform joist steel crossbeam of row, to form classification buffering.
Further, when being equipped with many row's crossbeams, applicable color can be used to carry out spraying for guiding sight line, such as, use yellow spraying at driving bend place.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, 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.
