Description

Urban road system Sign Board

One, technical field

Technical field belonging to this patent is: 1, and urban road Sign Board and picture and text casting pig manufacture thereof obtain; 2, corrosion treatmentCorrosion Science is done to corrosion resistant plate, to process the picture and text on urban road Sign Board, overpass Sign Board; 3, laser Special Working Technology specification, carves black word or dark word to obtain on the metal sheet of stainless steel, aluminium alloys, in order to manufacture overpass, excessively the street underground passage Sign Board of urban road system.To urban road Sign Board, overpass Sign Board, cross street underground passage Sign Board because infield is different the mount scheme of setting identification board, to be applied to city road administration engineering and management thereof, and be city pedestrian and social civilization service.

Two, background technology

In China, the scale in each city is all expanding with growing with each passing day, in the last few years along with the fast development of urban construction and the progress of road administration construction and management thereof, city is maximized and is made urban road, overpass, crosses street underground passage quantity in quick growth, meanwhile, its structure and scale are also complicated.Situation is in the past: urban road system, comprises urban road, overpass and crosses street underground passage, not arranging Sign Board to indicate this road, overline bridge, tunnel name, orientation, supervision unit, to safeguard the information such as unit and phone thereof.This kind of City Building of overpass, underground passage is without the title of public identification.Incity, city pedestrian, from different places, is wherein no lack of strange crowd.A large amount of urban roads there is no the mark such as road name, orientation, overpass and excessively street underground passage are then more without title, both inconvenient pedestrian identified it, and also inconvenient road administration department identifies it, supervises, safeguards, does not even facilitate public security department to the identification of its common name.This situation is unfavorable for the progress of city road administration and the rising of social civilization index.Also be the imperfection of administration of highways aspect, city.

The background technology of current city road administration system, overpass and excessively street underground passage do not arrange Sign Board, and the great majority of urban road do not arrange Sign Board, even if minority road arranges Sign Board, also road name, direction signs board just in the vertical rod of crossing setting, lack the supervision of more necessity, maintenance information and notification pipeline thereof.

Three, utility model content

The urban road of such as Beijing, overline bridge, tunnel, the quantity of often kind is all more than hundreds of respectively.This patent comprises the Sign Board of urban road, overpass, excessively street underground passage.Because Sign Board is exposed in air throughout the year, Sign Board palpus atmospheric corrosion resistance, can use corrosion resistant plate, casting pig, aluminium alloy plate, the manufacture of copper alloy plate material.Consider the factors such as copper alloy plate valency is high, then use that corrosion resistant plate, casting pig are cast, aluminium alloy plate is advisable.For road, overline bridge, genuine three kinds of situations, select certain material corresponding and structure, information needed picture and text in various situation on Sign Board front is done respectively.

These three kinds of Sign Boards of road, overline bridge, passage, the road sign board that what environment for use was the harshest is on pavement.If lay on pavement, one is the wearing and tearing after having pedestrian's pin to step on, and also will possess the measure of the pedestrian that prevents from slipping, can select casting pig that Sign Board board body has been cast together with picture and text on board to this, the picture and text of 3 ~ 4 millimeters high protruded not only are trampleed at one's discretion, also can play anti-skidding effect.Casting pig Sign Board wall thickness is about 6.5 ~ 7.5 millimeters, and the skirt is to concave edge 10 millimeters and at luminal perfusion concrete with pick-proof.Due to title, the orientation difference of every bar road, in order to reduce casting cost, when Mold Making, identical picture and text such as " maintenance unit and organization thereof " " maintenance telephone and number thereof " " supervision unit and organization thereof " " complaint telephone and number thereof " " management responsibility: road maintenance " and arrow etc. are all made in mastermold.Then make for word not identical on the Sign Board of different road, different sections of highway and embed in mastermold as Movable-type printing block.Also have an outstanding advantage with the road sign board of casting pig manufacture, because of its good antiskid effect, size can be done larger than corrosion resistant plate road sign board, and whole structure is more eye-catching, more air, more serious.Using casting pig manufacture, is the preferred option of road sign board.

Second scheme manufacturing road sign board is the corrosion adopting etch thin corrosion resistant plate to be made to required picture and text.The picture and text eroded away, than corrosion resistant plate surface indentation (general, picture and text cup depth is less than 0.5 millimeter), are then coated with dark colour paint in depression picture and text.The 3rd scheme manufacturing road sign board is the Sign Board adopting white bright thin corrosion resistant plate blank to produce black picture and text on laser machine, and picture and text are also depressions.The road sign board of second and third scheme manufacture can play little by little anti-skidding effect a little.

Because the title of each road, overline bridge, passage, orientation are different, when selecting the thin corrosion resistant plate blank of Bai Liang to make the picture and text of Sign Board on laser machine, special laser head is selected to laser machine, the setting parameter special processing process specification such as frequency, electric current, voltage of laser head when operation runs, the graph text information at high temperature burnt out is made to be black or dark color, compare with corrosion resistant plate background color bright in vain, not only eye-catching being easy to identified but also can keep more durable than the picture and text of serigraphy, etch japanning.

No matter adopt which kind of material to make road sign board, the blank of reserved 5 cm x 5 centimetres on Sign Board, as the position of doing scanning electron digital code information in the future on Sign Board.

Due to the difference of the Sign Board material of each road, overline bridge, passage, size, structure, infield, mounting method, the comprehensive above-mentioned factors of this case sets forth the technical scheme adapted.Following effect can be realized:

1, unified city administration of highways to road, overpass, cross the common name identification of street underground passage, convenient supervision, maintenance and maintenance;

2, facilitate pedestrian to the common name identification of urban road, overpass, excessively street underground passage.Owing to Sign Board leaving maintenance and supervision department's phone, once pedestrian finds road, overline bridge, genuine to damage, can press department's notification on Sign Board immediately with maintenance, reaching that pedestrian monitors at any time also can by the effect of the telephone report on Sign Board;

3, facilitate public security department to the common name identification of urban road, overpass, excessively street underground passage;

4, improve city administration of highways level, promote the progress of city road administration and the index of social civilization;

5, for doing scanning electron digital code information on Sign Board provides position in the future.

Technical scheme is described below.

The material of making Sign Board and picture and text thereof, technique, structure, infield, installing and fixing method factors interact.

Metallography is " in air, rustless steel is stainless steel " to stainless definition.In factory, stainless steel is commonly called as Bai Gang, gains the name because color and luster is bright in vain.Urban road system Sign Board all exposes in atmosphere, and therefore, the preferred material making Sign Board is casting pig and thin corrosion resistant plate.And the rigidity of aluminium alloy plate is little, is used as overline bridge Sign Board and is easily out of shape when being fixedly clamped.Make Sign Board and need do picture and text on metal, the method that metal does picture and text has casting, laser engraving, etch, serigraphy, sheet stamping etc.Sheet stamping first must make stamping die, and for big and medium-sized cities, road, overline bridge, passage sum are thousands of, and the cost making stamping die can not bear.Preparation method, the installation fixed solution of Sign Board and picture and text thereof determine its structure.When use laser engraving machine is on stainless steel, aluminium alloys, copper alloy during engraving text and picture, having only on stainless steel surfaces and to utilize the special processing process of laser machine can obtain black picture and text, in this case, the technical scheme of Sign Board make use of this technology joint.

1, road sign board

The first scheme manufacturing road sign board selects casting pig to cast.Planar dimension is about 320 × 480 millimeters by golden section proportion, is highly about 60 millimeters, and wall thickness is about 6.5 ~ 7.5 millimeters, and the picture and text 3-4 millimeter of protrusion is high, and the skirt is to concave edge 10 millimeters.Fixed solution has two:

One is by after casting pig road sign board luminal perfusion concrete, is embedded on the sidewalk at dental calculus place, contiguous road as embedding Footpath brick, road sign board end face and sidewalk levelling.Cast iron wall due to casting pig road sign board is designed with curved narrow limit in the skirt, chamber inner concrete is difficult to be removed, and can restrict the theft to casting pig Sign Board thus, even because steal Sign Board, because chamber inner concrete cannot take out, casting pig shell also just cannot be sold.See " Figure of description " Fig. 1.

Two is sidewalk upper concrete doll at contiguous dental calculus place, road, pillar planar dimension is less than the planar dimension of casting pig road sign board about 10 millimeters, highly about 450 millimeters, fluid concrete doll simultaneously, casting pig road sign board is buckled on pillar, make to be full of a certain amount of concrete in chamber, after pillar concrete setting, casting pig road sign board and concrete doll are condensed into one.Doll is set because exceeded road surface, relevant department's approval must be obtained.

On casting pig road sign board, the blank space except picture and text should design the protrusion anti-slip veins of some small circular or little rectangle.

The alternative plan manufacturing road sign board selects corrosion resistant plate, thickness 1.5 ~ 2.5 millimeters, and in order to reduce the possibility of the pedestrian that slips, planar dimension is unsuitable large, is about 200 × 220 millimeters.There are the picture and text on two kinds of methods making Sign Boards: one is adopt etch to erode away required picture and text, and generally, the picture and text cup depth eroded away is not more than 0.5 millimeter.Gained picture and text are identical with base metal color, then in the picture and text of depression, are coated with dark colour paint; Two is in laser machine, be equipped with special processing process standardized processing with special laser head go out black picture and text, and these method gained picture and text are more durable than etch japanning gained picture and text.

No matter on road sign board or overline bridge, on gap marker board, the blank area of 5 × 5 square centimeters be reserved, namely indicate the square of " scan code position " in exemplary plot, in order to doing scanning electron digital code information and reserved position in the future.In fact, because Sign Board area is enough large, these 5 × 5 square centimeters of blank positions are easy to be reserved.

Need to fix Sign Board with stone bolt, then need make four holes at Sign Board four angles place, in order to mounting foot bolt tightening Sign Board.Hole dimension and position and clamping bolt size thereof are shown in " five, detailed description of the invention ".If on overline bridge with bonding method fixed signal board (planar dimension 200 × 200 millimeters is that), then without the need to doing hole on the sign.With drift ping method fixed signal board, also without the need to doing hole on the sign.So do not draw hole in exemplary plot.

Beneficial effect is described below.

The position of casting pig road sign board is made on doll on the sidewalk of contiguous road dental calculus, having about 450 height can cause pedestrian to note, its boldness is that other technical scheme cannot by comparison, and the quality of casting is more serious, for city adds the little scape of one administration of highways.Now, all urban human trades are all provided with bicycle parking bracket, nobody proposes these parking brackets and can trip pedestrian and must ban.In like manner, also no one proposes casting pig road sign board doll and can trip pedestrian and must ban.On the contrary, the casting pig road sign board on doll more can solicit pedestrian pay close attention to, for pedestrian service while also shown administration of highways.Even if casting pig road sign board is on pavement embedding as Footpath brick, its abrasion resistance protruding the cast iron third dimension picture and text of 3-4 millimeter can be let people trample, again can be effectively anti-skidding, than corrosion resistant plate scheme more air, eye-catching, serious.

In the last few years, the conventional method doing picture and text is on a metal plate serigraphy.And silkscreen process is complicated: after the picture and text requirement that is in type in computer, in the platemaking machine of costliness, first must produce the plastic sheet with picture and text (be commonly called as and do pieces) as workpiece size, then printing down, select specialty inks carry out serigraphy, infrared heating sizing.Because the title of every overpass in city, Mei Tiaoguo street underground passage is different, orientation is different; Even same seat overline bridge or same underground passage, a pair of using (two pieces) Sign Board, because be placed on road both sides, its orientation is also different.So, for Beijing, if use serigraphy to make Sign Board, first must produce thousands of picture and text plastics pieces, then shape with the infrared heating of thousand times with the specialty inks serigraphy of thousand times, number with the printing down of thousand times, number through number.The picture and text printing finally obtained, under exposing to the sun and rain, its picture and text restricted lifetime.Because 300 × 450 millimeters of workpiece sizes are large, general machine is difficult to be competent at.The most important thing is, the picture and text that screen printing brushes out, the picture and text that its firmness processes less than laser machine.

Generally, the contrast of the picture and text carved through laser machine of stainless steel and stainless steel parent true qualities is little.But, adopt special laser head, set the special processing process of laser machine, black picture and text can be obtained, make picture and text and this color contrast of stainless steel parent greatly, watch eye-catching.To thousands of sign board blanks good according to measure, every compact material carries out laser engraving under being placed on laser engraving machine, disposablely can obtain the black picture and text gone out by laser burn completely, and namely operation simply prints the content on different page number paper as printer.This be must the sheet stamping of first mfg. moulding die or serigraphy to obtain the complicated procedures of forming of picture and text incomparable.Because black picture and text are burnt out by laser, its picture and text tackle life-span of exposing to the sun and rain much larger than serigraphy.The Sign Board that the method processes is fewer than the operation of serigraphy, consuming time short, processing speed is high, cost saving, picture and text life-span are long.

Following effect can be realized after implementing this patent:

1, unified city administration of highways to road, overpass, cross the common name identification of street underground passage, convenient supervision, maintenance and maintenance;

2, facilitate pedestrian to the identification of urban road, overpass, excessively street underground passage.Owing to Sign Board leaving road administration department telephone, once pedestrian finds road (such as manhole cover loss), overline bridge, genuine to damage, road administration department can be reported immediately with maintenance, reach pedestrian and to monitor at any time and can by the effect of the telephone report on Sign Board;

3, facilitate public security department to the common name identification of urban road, overpass, excessively street underground passage;

4, improve city administration of highways level, promote the progress of urban civilization and the index of social civilization;

5, for doing scanning electron digital code information on Sign Board provides position in the future.

Five, detailed description of the invention

1, the plane meter 320 × 480 millimeters of the road sign board of casting pig casting, first plan of establishment is embedded on the sidewalk at dental calculus place, contiguous road by after casting pig road sign board luminal perfusion concrete as Footpath brick, road sign board end face and sidewalk levelling.Casting pig casting will economize than the road sign board scheme of corrosion resistant plate.See " Figure of description " Fig. 1.

Road sign board second plan of establishment of the casting pig casting that planar dimension is 320 × 480 millimeters is: at sidewalk upper concrete doll at contiguous dental calculus place, road, pillar planar dimension 310 × 470 millimeters, the height of pillar more than ground 450 millimeters, the foundation depth of below ground 180 ~ 200 millimeters, fluid concrete doll simultaneously, casting pig road sign board is buckled on pillar, make to be full of a certain amount of concrete in chamber, after pillar concrete setting, casting pig road sign board and concrete doll are condensed into one.

2, the road sign board size that thin corrosion resistant plate etch manufactures picture and text is about 200 × 220 millimeters.Three kinds of schemes can be used to be fixed on pavement:

Scheme a such as Fig. 3 is provided with 4 anchor (bolt) hole 4 Φ 6.5 millimeters in Sign Board corner, 10 millimeters, centerline hole distance edges of boards line.For filling 4 M6 stone bolt, bolt head is semicircle, when this kind of road sign board is installed, be selected in the Footpath brick of contiguous road, sidewalk dental calculus, first take out the Footpath brick of respective area, penetration concrete in this brick hole, Sign Board is placed on concrete, Sign Board surface is levelling with road surface, sidewalk, and will insert in concrete in four holes of 4 cup head stone bolt key press-bending Qu Houcong Sign Boards, after concrete setting, then Sign Board, bolt and concrete coagulation be integrated.The use of this kind of method is not by the limitation of Footpath brick size.Namely facilitate and adopt when Footpath brick size is little.After concrete coagulation, because Sign Board and ground, sidewalk are in same level, Sign Board is not easily fallen by sled.4 cup heads of bolt can play some anti-skidding effects.

Second scheme does not establish anchor (bolt) hole in Sign Board corner, the round steel of common steel of four diameters 5 ~ 6 millimeters, length 30 ~ 40 millimeters is welded respectively in corner, the Sign Board back side, these four round steel short columns are lower margin, four lower margins and Sign Board vertical direction will be kept during welding to keep unordered inclination 5 ~ 10 degree of angles, be selected in the Footpath brick of contiguous road, sidewalk dental calculus, first take out the Footpath brick of respective area, penetration concrete in this brick hole, by the lower margin press-in concrete of four on Sign Board, until Sign Board front and sidewalk plane maintain an equal level.After concrete setting, because Sign Board and concrete became one, Sign Board can not be prized.See " Figure of description " Fig. 3.

3rd scheme is shown in " Figure of description " Fig. 5.Do not establish anchor (bolt) hole in Sign Board corner, four diameters 6 ~ 8 millimeters are welded respectively in corner, the Sign Board back side, the round steel of the common steel of length 30 ~ 50 millimeters, these four round steel short columns are called drift ping, four drift pings will be kept during welding perpendicular to Sign Board, be selected in the Footpath brick of contiguous road, sidewalk dental calculus, rule on Footpath brick according to the relative size of four drift ping center lines, select chopping bit diameter less than drift ping diameter 1 ~ 1.5 millimeter, on the Footpath brick of line, 4 upright openings are made a call to Churn drill, hole depth is greater than drift ping length 5 millimeters, four of Sign Board drift pings are aimed at 4 percussive drillings on Footpath brick, by in Sign Board drift ping press-in hole, hitting the drift ping back side with wooden mallet from Sign Board front makes drift ping wedge enter percussive drilling, finally make the Sign Board back side and Footpath brick plane be adjacent to and become integral structure.Because small size Footpath brick is easy in the impact drilling process cracked, be only suitable for the large Footpath brick of size in this approach.

Sign Board on every bar road is arranged on road both sides, and every side at a certain distance (such as 300 ~ 500 meters) is arranged a pair (i.e. each one piece of road both sides).In order to prevent road sign board surface to slip pedestrian, the unsuitable size of corrosion resistant plate Sign Board is large, can be not more than 450 square centimeters.

Because road sign board is arranged on road both sides, the Chinese character in the sign direction (east and west, Nan Yubei) in Sign Board is different.This just need city road administration designer will consider when assigning a task book this block identification board is arranged on which side of road, must be carefully clearly practicable.

Preferred plan is for road sign board arranges column specially, and road sign board is fixed on column.The method awaits forming social recognition and custom, advantage be road sign board do not trampleed on by pedestrian, anti-skidding, eye-catching, serious, after especially establishing scan code.

3, the corrosion resistant plate manufacture of overpass Sign Board, size has two schemes:

The first scheme is Sign Board planar dimension 300 × 450 millimeters, and each overline bridge arranges two pieces: be fixed on the railing waist in overpass platform end positions, bolt hole 4 Φ 9 millimeter of corner for tightening up, 12 millimeters, centerline hole distance edges of boards line.For filling 4 M8 set bolts.

The railing waist of installation site on overpass position of platform.In order to tighten up overline bridge Sign Board, the clamping plate that need manufacture with two band steels or angle steel are supporting.Make band steel thickness 6 millimeters or edge of a wing thickness 4.5 to 5 millimeters of angle steel of clamping plate, every root clamping plate length is identical with overline bridge sign board length, two hole Φ 9 ~ 10 millimeters processed by every root clamping plate, and hole center to center distance is identical with two hole center to center distance in overline bridge Sign Board length.If it bridge railings uses the round steel of external diameter 25 millimeters, then select the hexagon-headed bolt of four pairs of M8 × 40, nut and two clamping plate, then one piece of overline bridge Sign Board can be clamped railing and Sign Board is fixed on the waist of day bridge railings.For lock screw, tighten up the rear bolt thread being exposed at outside nut and destroy, or with spot welding method, bolts and nuts are welded together.The former is simple; The latter's reliability is strong.

First scheme is Sign Board planar dimension 200 × 220 millimeters, is fixed in the plastic plate on ground, overpass platform two ends.Because illustrate orientation, an overline bridge platform is arranged two block identification boards and be advisable.Choose and lessly trampled installation site eye-catching again, first 200 × 220 millimeters of plastic cement are taken out from platform dough model glue during installation, clean out inclusion particles, double faced adhesive tape is applied at 200 × 220 millimeters of recess, Sign Board is placed on compacting on double faced adhesive tape, for make Sign Board front and platform plastic floor levelling, to take out the thickness of 200 × 220 millimeters of plastic cement from platform dough model glue identical with double faced adhesive tape+Sign Board thickness.See Fig. 7.

4, cross street underground passage Sign Board size and be about 300 × 450 millimeters, Sign Board is fixed on the wall at passage two ends, and distance ground level is about 1.5 ~ 2.2 meters and is advisable.Fixing means has two:

First method is shown in " Figure of description " Fig. 5.Sign Board corner atresia, four diameters 8 millimeters are welded respectively in corner, the Sign Board back side, the round steel of the common steel of length 40-50 millimeter, these four round steel short columns are drift ping, four drift pings will be kept during welding perpendicular to Sign Board, Sign Board position installed by selected passage gable, rule on gable according to the relative size of four drift ping center lines, select chopping bit diameter less than drift ping diameter 1.0 ~ 2.0 millimeters, on the gable of line, 4 upright openings are made a call to Churn drill, hole depth is greater than drift ping length 5 millimeters, four of Sign Board drift pings are aimed at 4 percussive drillings on gable, by in Sign Board drift ping press-in hole, hitting the drift ping back side with wooden mallet from Sign Board front makes drift ping wedge enter percussive drilling, finally make the Sign Board back side be adjacent to into gable plane to be integrated.

Second method is bolt hole 4 Φ 10 millimeter of Sign Board corner for tightening up, 12 millimeters, centerline hole distance edges of boards line.For filling 4 M8 expansion bolts.Gap marker board is arranged on the gable below entrance to a tunncl, uses 4 M8 expansion bolts to be fixed on the wall by gap marker board.The method of locking gap marker board has be tighten the nut of expansion bolt after at two: one, destroys and is exposed at the outer screw thread of nut; Two is welded together by bolts and nuts with spot welding method.The former is simple; The latter's reliability is strong.
