Description
Technical Field
The invention belongs to the field of structural design of anti-dazzle nets or guard railings, in particular to a long-span anti-dazzle glass fiber reinforced plastic isolation net, which relates to the application technology of glass fiber reinforced plastic and is used for shading in the middle of a road or isolating and protecting two sides of the road.
Background
When an automobile runs on an expressway, the automobile is often influenced by strong light irradiation on headlamps of the automobile, and the glare can cause reduction of visual function and discomfort of eyes of a driver, easily causes tension and fatigue, even cannot see the road surface ahead clearly, and is a potential or indirect factor for traffic accidents. In order to effectively reduce the influence of glare on drivers during meeting at night and ensure driving safety, anti-glare facilities are usually arranged in central banks of roads such as expressways, first-level roads, railways and the like.
At present, three main anti-dazzle forms are plant anti-dazzle, anti-dazzle plate anti-dazzle and anti-dazzle net anti-dazzle. However, when planting anti-dazzle plants in the middle of roads in a zone with a severe environment, the problems of difficult survival, high maintenance cost and the like exist. The anti-dazzle plate has larger windward area, is easy to break in windy weather, and has higher manufacturing cost due to thick material and high strength.
The anti-dazzle isolation net is characterized in that isolation grids with certain width and height are continuously arranged at a road central dividing strip, and isolation rods on the isolation grids can play an anti-dazzle role. When the light beam of the car headlamp strikes the isolation barrier, the light beam can be blocked by the adjacent isolation rods, so that the requirement of shading is met. Meanwhile, the anti-dazzle isolation net also meets the requirement of good transverse visibility, so that a driver can observe the condition of the opposite oblique front of the road, the anti-dazzle isolation net also plays a role in isolation and protection, and has good road appearance landscape in daytime.
The existing anti-dazzle net used in the middle of the expressway has two types, namely a metal anti-dazzle net and a glass fiber reinforced plastic anti-dazzle net. The metal net is mostly a steel plate stretching net, and is easy to rust, lose, use a large amount of steel and waste steel resources, and the metal net needs to be subjected to acid pickling and galvanizing, so that the influence on the environment is large; in recent years, under the high pressure situation of national environmental protection requirements, enterprises with unqualified environmental protection and poor integrity steal work and reduce materials, a galvanizing process of a metal net is cancelled privately, and thin-walled tubes and steel plate nets with unqualified thicknesses are adopted, so that the phenomena of skin explosion, rust holes, rust breakage, breakage and the like can occur continuously after the metal anti-dazzle net is used for 3-5 years.
Utility model CN201120451678.3 discloses a glass steel anti-dazzle net, including stand, frame and spacer bar, this spacer bar plays anti-dazzle effect. The height and the interval of stand are 1.5 ~ 2 meters, and the middle part and the top of stand are pegged graft respectively in last horizontal pole, the sheer pole of frame, peg graft in the middle of going up horizontal pole and the sheer pole have a plurality of spacer bars and 1 ~ 3 straight ribs. The anti-dazzle and protective net disclosed by the appearance patent CN201530036763.7 comprises a cross rod, a vertical rod, straight ribs and an isolating rod, wherein the diameters of the cross rod and the vertical rod are larger than the diameters of the isolating rod and the transverse ribs.
The isolation net is usually arranged on two sides or around roads, railways, airports, bridges and the like, and mainly plays a role in safety protection and isolation. The isolation net is mainly formed by connecting a plurality of vertical isolation bars with a grid-shaped or net-shaped isolation fence formed by interlacing a plurality of transverse ribs. Utility model CN200920101783.7 discloses a glass steel barrier fence, comprises a plurality of intervals for 3 ~ 15 centimetres spacer bars and straight rib.
The interval between adjacent upright columns of the currently used glass fiber reinforced plastic anti-dazzle isolation net disclosed in the above patent is generally only 1.5-2.5 m. The longer the column interval of the anti-dazzle isolation net or the length of the upper and lower transverse rods of the frame is, the more easily the anti-dazzle isolation net sags, and in order to prevent the sagging, the span between the adjacent columns of the existing glass fiber reinforced plastic anti-dazzle isolation net cannot be too large. Therefore, when the anti-dazzle isolation net is installed, the usage amount of the stand columns is very large, a large amount of stand column foundations or steel structure supports need to be built in the middle of a road correspondingly to be fixed, and the problems of resource waste, high construction cost and large construction labor amount exist.

The technical scheme of the invention is further improved as follows: the upper cross rod, the lower cross rod and the ribs of the arch are straight or have a curvature smaller than that of the spacer rod after being worn in a free state, and the arch is formed after the spacer rod is assembled.
The technical scheme of the invention is further improved as follows: the isolation rods, the upper cross rod, the lower cross rod and the ribs are of an inserting structure; holes which are tightly matched with the isolating rods are arranged on the upper cross rod, the lower cross rod and the ribs, and the isolating rods penetrate through the holes on the upper cross rod, the lower cross rod and the ribs; after the isolation barrier is assembled, the holes in the upper cross rod, the lower cross rod and the ribs are vertical.
The technical scheme of the invention is further improved as follows: when the upper cross bar is in an upper arch shape or the lower cross bar is in a lower arch shape, ribs are not arranged between the upper cross bar and the lower cross bar; the isolating rod, the upper cross rod and the lower cross rod are of a penetrating structure, holes which are closely matched with the isolating rod are formed in the upper cross rod and the lower cross rod, and the isolating rod penetrates through the holes in the upper cross rod and the lower cross rod.
The technical scheme of the invention is further improved as follows: when the upper cross rod and the lower cross rod are in a straight shape, the ribs further comprise at least one straight rib, and the arched ribs are positioned at the upper part and the lower part of the straight rib or between the two straight ribs.

The technical scheme of the invention is further improved as follows: the split tee pipe further comprises a structure that side pipes do not extend out of two sides of the vertical pipe or the side pipes extend out of the vertical pipe to be short; the split-type four-way pipe is a structure with no extending end at the upper end and the lower end of the vertical pipe or the vertical pipe extending to a shorter length.
Due to the adoption of the technical scheme, the invention has the technical progress that:
the anti-dazzle isolation net provided by the invention can well solve the problem that the long span of the anti-dazzle isolation grid is easy to sag, so that the spacing distance between adjacent stand columns is lengthened, the use amount of the stand columns is reduced, the material consumption and the engineering cost are reduced, the field installation workload is reduced, the structural strength is increased, and the durability is improved; because the anti-dazzle isolation net and the upright post adopt split type connecting pieces which are split front and back, the installation, the maintenance and the replacement are more convenient and faster; meanwhile, the device has the advantages of light and concise structure, attractive and elegant appearance, good dynamic vision and the like.
When the isolation fence is assembled, the upper cross rod which is flat and straight in a free state is bent into an upper arch shape, the lower cross rod is bent into a lower arch shape, or the ribs are bent into an upper arch, a lower arch or waves, then the isolation rod is worn on the arched cross rod or rib, and the vertical isolation rod is always subjected to supporting force due to the tension action of the arched cross rod and ribs, so that the problem that the anti-dazzle isolation net is easy to sag when the span is longer can be solved. The upper transverse bar, the lower transverse bar and the ribs are straight or have only a small degree of free bending in the free state. When the glass fiber reinforced plastic spacer bars penetrate through the holes arranged on the upper cross bar, the lower cross bar or the ribs, the upper cross bar, the lower cross bar or the ribs can be fixed among the spacer bars and bent to form arched cross bars or ribs, and elastic acting force is generated on the spacer bars which are contacted but do not deform obviously. When the upper cross bar is in an upper arch shape or the lower cross bar is in a lower arch shape, the length of the isolation rod is changed along with the curvature of the upper arch or the lower arch. When the cross bar is in the shape of an arch, the isolating fence can not comprise arched ribs or straight ribs, or can comprise arched ribs and straight ribs. Within the elastic limits of the arched ribs or rails, the elastic action on the spacer bars is greater when the arched ribs or rails are bent to a greater extent or are deformed more greatly than in the free state.
The shape and the aperture size of the hole arranged on the upper cross rod, the lower cross rod, the straight ribs and the arched ribs are consistent with the shape and the thickness of the isolating rod, so that the upper cross rod, the lower cross rod, the straight ribs and the arched ribs are closely matched, the connection is more firm, a certain supporting effect is achieved, the integral mechanical strength is enhanced, the anti-dazzle isolating net is firmer and more durable, and the service life of the anti-dazzle isolating net is prolonged.
The arched cross rods and the arched ribs arranged on the anti-dazzle isolation net are light in material and simple in structure, excessive load or windward resistance cannot be added to the anti-dazzle isolation net, the processing cost is low, and the assembly is very convenient. Only need after the design crookedness, punch according to the shape and the thickness of spacer bar, the interval between the adjacent hole depends on crookedness and the interval of spacer bar after the horizontal pole of arcade and rib are assembled. The arched cross rods and ribs are kept in a flat plate shape before assembly, and the upper cross rods, the lower cross rods, the ribs and the isolating rods can be inserted, molded and assembled at one time by using a mechanical assembly platform of a processing plant.
The anti-dazzle isolation net has small windward area, is not easy to be damaged in windy weather and has lower maintenance cost. When the anti-dazzle isolation net is used for anti-dazzle function in the middle of a road, the height of the isolation fence is generally 70-100 cm, namely, the lower cross bar is flush with or slightly lower than the top surface of a guardrail of the central separation belt, and the anti-dazzle effect is prevented from being influenced by light leakage of a gap between the lower cross bar and the top surface of the guardrail. The shading angles of the spacer bars with different thicknesses, shapes and spacing distances are also different. The smaller the distance between the isolating rods with the same thickness is, the better the shading effect is, but the poorer the transverse permeability is; on the contrary, the larger the distance, the poorer the shading effect and the better the permeability. When the isolation barrier is used for isolating and protecting two sides of a road, the height of the isolation barrier is generally 150-180 cm, and the distance between the lower cross bar and the ground is 10-15 cm.
The invention adopts the glass fiber reinforced plastic as the material of the anti-dazzle isolation net, and compared with metal materials, the anti-dazzle isolation net has the advantages of light weight, acid and alkali resistance, corrosion resistance, non-conductivity, no theft value, steel saving, energy conservation, emission reduction and the like. Meanwhile, the glass fiber reinforced plastic has certain elasticity and plasticity, and can meet the use requirements of no load increase, convenience in bending, firmness and durability when used for manufacturing arched cross bars or ribs. If the surface of the anti-dazzle isolation net is subjected to spraying treatment, the anti-dazzle isolation net can further enhance the performances of corrosion resistance, acid and alkali resistance and ageing resistance, prolong the service life of the anti-dazzle isolation net and increase the attractiveness and visual comfort of the anti-dazzle isolation net.
The invention uses the split type pipe fittings to connect and fix all the parts, so that the assembly and disassembly are simpler and more convenient during installation and maintenance. The split type pipe fitting is of a front-back split type structure and consists of a front half piece and a back half piece which are completely symmetrical. When the isolation fence is assembled, the vertical rods are placed at the preset positions of the cross rods, the front half piece and the rear half piece of the corresponding pipe are used for clasping, and then the vertical rods are fixed through bolts. When the anti-dazzle isolation net is installed, the stand columns are firstly embedded into a concrete foundation according to a set interval or fixed on a steel bracket of a bridge and culvert structure or a central integral concrete guardrail through split flanges, then the upper cross rod and the lower cross rod of the pre-assembled isolation fence are placed at corresponding height positions of the stand columns and are directly fixed with the stand columns through split pipe fittings. The split type pipe fitting can well solve the problems that the traditional non-split type pipe fitting can only be inserted or drawn out in sequence from one end and is inconvenient to assemble and disassemble after the interval is fixed, so that associated parts needing to be disassembled during maintenance are greatly reduced, the installation efficiency is obviously improved, and the construction progress is accelerated.
The split special-shaped tee joint and the special-shaped cross joint used by the invention comprise a main pipe in the vertical direction and side pipes on two sides. The side pipe of the split type special-shaped tee joint has a certain inclination angle with a horizontal line, an included angle formed between the axis of a main pipe of the split type special-shaped tee joint and the axis of the side pipe is a non-vertical included angle, and the included angle corresponds to the arch shape and the curvature of the cross rod, so that the arch cross rod is more convenient to install and more stable to fix. The parts of the upper and lower cross bars of the separation fence extending outwards are respectively connected with the upright post through a tee pipe fitting and a four-way pipe fitting. When the lower cross rod is arched downwards, the main pipe and the side pipe are arranged in a non-vertical mode, and when the lower cross rod is straight, the main pipe and the side pipe are arranged in a vertical mode, the opposite-opening type special-shaped four-way is used. The split special-shaped four-way pipe has the advantages that the outward extending pipe wall of the vertical pipe at one end is omitted, the outward extending pipe wall of the side pipe is omitted for the split special-shaped three-way pipe, or the extending lengths of the side pipe and the vertical pipe are shorter, the improvement can reduce the dead weight, reduce the cost, save the materials and meet the requirement of environmental protection.
The span (the distance between adjacent upright posts) of the existing glass fiber reinforced plastic anti-dazzle isolation net is generally 1.5-2.5 m, and under the condition that the height, the material and other structures are completely the same, the effect of prolonging the span by about one time can be achieved by only improving the arched cross rods or ribs. One set of upright post, upright post foundation or corresponding metal steel support, two upright posts and corresponding fixed connecting pieces can be saved every 4-6 m of length of the anti-dazzle isolation net. Therefore, the anti-dazzle isolation net for the long-span highway, provided by the invention, can save a large amount of resources, cost and labor input, shortens the installation period, brings higher social benefit, economic benefit and environmental benefit in the long term and comprehensive effect, has good application prospect, and particularly can well solve the problem of sag of the isolation fence.
