Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out detailed retouching
State, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the present invention
In embodiment, the every other enforcement that those of ordinary skill in the art are obtained on the premise of not making creative work
Example, broadly falls into the scope of protection of the invention.
Shown in Fig. 1, urban interchange, steel construction build, it includes supporting frame with steel structure and is layed in
Steel grating 3 on supporting frame with steel structure.Supporting frame with steel structure includes the steel structure frame 1 being formed at both sides, road surface and connects
Auxiliary beam 2 between steel structure frame 1, steel grating 3 is installed on auxiliary beam 2.
Steel structure frame 1 is in I-shaped or II shape, and it includes setting up and down two crossbeam 11 and is fixed on two horizontal strokes
At least one support beam 12 between beam 11, is welded and fixed by Type of Welding between support beam 12 and crossbeam 11.Type of Welding
Weld seam be full penetration, ginseng Fig. 2 shown in.
Shown in Fig. 3 and Fig. 4, auxiliary beam 2 being fixed with plate-girder 4, steel grating 3 is installed on plate-girder 4, the end of steel grating 3
Face is fixed with multiple horizontal stripes 34 of array distribution, is detachably fixed by bolt between horizontal stripe 34 and plate-girder 4, and horizontal stripe 34 is supported in
So that forming a clearance space 35 bottom steel grating 3 and between plate-girder 4 between steel grating 3 and plate-girder 4.
Further, cushion it is provided with between horizontal stripe and the contact surface of plate-girder.
Further, steel grating 3 includes that multiple taeniaes 31 of array distribution, cross bar 32 and side wrapped plate 33, cross bar 32 are fixed
In the end face of multiple described taeniaes 31, vertical between this cross bar 32 with taeniae 31 being connected, side wrapped plate 33 is fixed on the end of taeniae 31
Portion, is vertically arranged between horizontal stripe 34 and taeniae 31.
In this technical scheme, horizontal stripe makes to be tightly fastened between steel grating and plate-girder by bolt, simultaneously facilitate installation and
Detachable maintaining.
It addition, by arranging horizontal stripe, so that it is not directly contacted with between taeniae and plate-girder upper surface, on slab and girder
Locally water can be got rid of in time by clearance space horizontal mobility.
Further, taeniae 31 is as main bearing carrier, the most flat band steel or I shaped steel.
Further, cross bar 32 is twisting square steel, provides necessary frictional force for steel grating upper surface.
Further, side wrapped plate 33 is flat band steel.
Further, pressure welding molding is used between taeniae 31 and cross bar 32.
Further, horizontal stripe 34 is flat band steel, is welded and fixed between itself and the bottom surface of taeniae 31.
Further, the upper surface of horizontal stripe 34 is located substantially at same plane with the upper surface of described taeniae 31.
In this technical scheme, horizontal stripe is not higher than taeniae end face so that it is have good flatness, can greatly reduce traveling
The noise of vehicle interior.
Further, taeniae and cross bar surround the grid with multiple square orifice, the size of square orifice be 4.8cm ×
4.8cm。
In this technical scheme, square-grid anisotropic is better than square grid, and this form is unfavorable for the individual direction of vehicle
Driving performance, it is therefore desirable to improve, through a large amount of tests and analysis, uses the square grid of a size of 4.8cm × 4.8cm, should
Structure can be improved attachment condition by making full use of tire depression and will not deteriorate ride comfort.
The steel grating structure of this case not only has good vertical drainability, and can provide the friction of abundance for tire
Power.
Shown in Fig. 1, the lower section of steel grating is provided with water leg 5, and this water leg 5 includes U-shaped corrosion resistant plate contour plate
51 fix with U-shaped corrosion resistant plate contour plate 51 by loosening nut with connection adnexa 52, the bottom connecting adnexa 52, connection adnexa
The top of 52 is connected to the lower crossbeam of steel structure frame 1 by a coupler body.
Connect and be provided with ethylene-propylene-diene monomer rubber cushion between adnexa 52 and the contact surface of U-shaped corrosion resistant plate contour plate 51.
In this technical scheme, connected by check bolt nut, it is ensured that in-site installation and later maintenance are keeped in repair just
Victory, stop nut can be reused after dismantling simultaneously.
Additionally connect adnexa to be connected by check bolt nut between U-shaped corrosion resistant plate contour plate 51, it is possible to reduce two
Plant the probability of the identical natural frequency of material, to reduce the generation of covibration, padded by ethylene propylene diene rubber existing simultaneously
Noise reduction process.
Further, in U-shaped corrosion resistant plate contour plate 51, spaced set has multiple horizontal stop plank.
Further, horizontal stop plank offers through hole.
Further, water leg 5 outwards draws drain pipe between adjacent two horizontal stop planks.
Further, U-shaped corrosion resistant plate contour plate material is added with molybdenum element.
Further, U-shaped corrosion resistant plate contour plate surface is formed with passivating film.
Further, connect between adnexa and the contact surface of U-shaped corrosion resistant plate contour plate and be provided with cushion.
In this technical scheme, Corrosion Protection is an important index in the design of water leg, from environment, air,
The aspects such as dirt, material alloys element are comprehensively analyzed, and owing to the addition of molybdenum element in stainless steel material, its surface is formed simultaneously
Passivating film, its antiseptic property is more preferable than other materials durability.
Further, connect between adnexa 52 and steel structure frame by being welded and fixed.
In this case, rainwater passes through steel grating road surface, is collected to the water leg below grid road surface, enters ground along gradient incline
Lower drainage pipeline networks.By spaced horizontal stop plank and drain pipe, rainwater can be concentrated and lead to ground, and then pass through
Land drainage imports underground sewerage system.
Shown in Fig. 5, the lower section array distribution of bridge floor 6 has multiple strong point, between each strong point and ground respectively
Support has a support column, adjacent four rectangular distributions of the strong point, is respectively arranged with laterally movable bearing at these four strong points
61, hold-down support 62, multidirectional movable bearing support 63 and longitudinally-moving bearing 64.
Further, laterally movable bearing 61 and longitudinally-moving bearing 64 are positioned at diagonal；Hold-down support 62 is multidirectional
Movable bearing support 63 is positioned at diagonal.
In this technical scheme, bridge can control between 7～14Hz with the frequency of vibration that dynamic load causes by four bearings, from
And realize decrease of noise functions.
Further, laterally movable bearing 61, hold-down support 62, multidirectional movable bearing support 63 and longitudinally-moving bearing 64 and bridge
Between the contact surface in face and and the contact surface of support column between be provided with cushion.
Further, support column is steel pipe, is filled with cement in the cavity of this steel pipe.
