Description

中空护栏板 Hollow guardrail

技术领域 Technical field

本发明属于道路交通安全设施技术领域，涉及一种护栏板，尤其涉及一种中空护栏板。背景技术 The invention belongs to the technical field of road traffic safety facilities, and relates to a guardrail board, in particular to a hollow guardrail board. Background technique

高速交通围护、大型场地围护常需要使用防护板或护栏，使用领域广泛，涉及交通、农业、娱乐、工业、建筑等多个行业，例如护栏常用于农业上的牲畜圈养、大型居住区、高速公路、桥梁、大型工业基地和大型娱乐场所如赛马场、赛车场等的安全防撞设施。 High-speed traffic envelopes and large-scale site enclosures often require the use of protective panels or guardrails. They are used in a wide range of fields, including transportation, agriculture, entertainment, industry, construction, etc. For example, guardrails are often used for livestock keeping in agriculture, large residential areas, Safe collision avoidance facilities for highways, bridges, large industrial bases and large entertainment venues such as racetracks and race tracks.

其中，最为重要的安全防护是交通，特别是高速公路、快速路和桥梁，都需要护栏，护栏的主要作用是对行驶车辆防护，防止车辆出现意外时冲出道路造成更大人员和车辆损失。现有的护栏基本上采用波形梁钢护栏，这种护栏通常采用带有 2~ 3个半波的波纹状冷轧钢板作为护栏板，该护栏板相互搭接或通过连接件相互拼接并由立柱支撑，或通过防阻块与立柱连接组成连续的道路防撞护栏结构，并利用土基、立柱、防阻块、波形护栏板的变形来逐步吸收碰撞能量，迫使失控车辆改变方向。但这种钢梁的护栏板表面容易锈蚀，其外观差、使用寿命短，即使完好无损也要定期全面维护，综合造价与维修费用较高。并且钢梁制成的护栏板硬度高、刚性大，失控车辆与栏板相撞的接触时间短，因此吸能能力较差，对车辆和乘员的危害较大。 Among them, the most important safety protection is transportation. Especially for highways, expressways and bridges, guardrails are needed. The main function of the guardrail is to protect the moving vehicles and prevent the loss of more people and vehicles when the vehicles are accidentally rushed out of the road. The existing guardrail basically adopts a corrugated beam steel guardrail. The guardrail usually adopts a corrugated cold-rolled steel plate with 2~3 half-waves as a guardrail board. The guardrail boards are overlapped with each other or are connected to each other by a connecting piece and are connected by a column. Support, or through the anti-block block and the column to form a continuous road crash barrier structure, and use the deformation of soil foundation, column, anti-block, wave guardrail to gradually absorb the collision energy, forcing the out-of-control vehicle to change direction. However, the surface of the guardrail of the steel beam is apt to be rusted, and its appearance is short and the service life is short. Even if it is intact, it should be fully maintained on a regular basis, and the overall cost and maintenance cost are high. Moreover, the guardrail plate made of steel beam has high hardness and rigidity, and the contact time between the uncontrolled vehicle and the slab is short, so the energy absorbing ability is poor, and the damage to the vehicle and the occupant is large.

基于钢护栏的上述缺陷，出现了 "以塑代钢"制成的护栏板，如公开号为 CN2350430A的中国专利《一种柔性道路护栏》，公开了采用 PE塑胶材料搪塑而成的 "B" 字形空心结构来提高护栏板的减振性和柔性。公开号为 CN101023222A的中国专利《树脂护栏》公开了通过树脂模压制成，波浪形截面、横肋交替排列的空心蜂窝板状基体，使护栏板具有较高强度和减震功能。上述护栏板 "以塑代钢" 的技术解决方案虽然解决了钢护栏容易锈蚀、外观差、使用寿命短、吸能能力较差、对车辆和乘员的危害较大的问题，但由于要做到防止车辆越出路外，必然要求护栏具有相当的力学强度和刚度，才能抵挡车辆的冲撞，而塑料的材料弹性模量只有钢的 200 分之一（如碳素钢的材料弹性模量在 190000 Mpa左右，聚乙烯（PE)的材料弹性模量在 800Mpa 左右），这种全塑料结构的护栏就需要耗用较多的材料才能达到钢护栏要求的强度，因此全塑护栏的体积大、成本很高，不利于推广使用。 Based on the above-mentioned defects of the steel guardrail, a guardrail plate made of "plastic-made steel" has appeared, such as the Chinese patent "a flexible road guardrail" with the publication number CN2350430A, which discloses a "B-plasticized plastic material". "Glyph hollow structure to improve the vibration damping and flexibility of the guardrail. The Chinese patent "Resin Guardrail" of the publication No. CN101023222A discloses a hollow honeycomb plate-like substrate which is formed by resin molding and has a wave-shaped cross section and lateral ribs alternately arranged, so that the guardrail plate has a high strength and a shock absorbing function. The technical solution of the above-mentioned guardrail "to replace the steel" has solved the problem that the steel guardrail is easy to rust, has poor appearance, short service life, poor energy absorbing ability, and great harm to vehicles and occupants, but To prevent the vehicle from getting out of the road, it is necessary to require the guardrail to have considerable mechanical strength and rigidity to withstand the collision of the vehicle. The elastic modulus of the plastic is only one-twentieth of the steel (for example, the elastic modulus of the carbon steel is 190000 Mpa). Left and right, the elastic modulus of polyethylene (PE) is about 800Mpa). This all-plastic structure of the guardrail requires more material to reach the strength required by the steel guardrail. Therefore, the plastic fence is bulky and costly. High, not conducive to promotion.

"钢塑复合"是另一种解决方案。如公开号为 CN1393600A的中国专利《复合材料公路护栏及其生产方法》提出了内埋钢筋或钢丝网，并与不饱和树脂、辅料、玻璃丝布层模压复合的护栏。公开号为 CN2644499A的中国专利《道路护栏构件》提出在钢板或带钢通过冷弯加工成型的波形护栏板表面覆盖复合挤出成型的高分子材料层。上述钢塑复合材料的护栏方案中，模压复合的方式无法连续生产，导致生产效率较低；在波形钢护栏板表面挤塑，其工艺较为复杂使其成本上升。更为重要的是现有的塑钢护栏产品中塑钢之间存在相容性的问题，塑钢之间的剥离强度较低，在使用和安装过程中易因塑钢分离，使其强度和韧性不足，达不到使用要求并易出现破损；且塑钢热胀冷縮的收縮系数不同，塑钢之间热胀冷縮后两种材料之间会出现相对滑移使二者的接合面存在空隙，将导致湿气从材料表面的破损处沿接合面的空隙进入腐蚀内部的钢材，降低护栏板的使用寿命，并造成安全隐患。并且上述塑钢护栏都是硬质护栏，或因塑钢易分离不能收卷和弯曲，造成运输和储存不便，且因护栏板长度有限，安装所需配件较多，使其安装繁琐。并且上述塑钢护栏还是以中间钢结构材料为主要支撑部件，其外部复合的塑料只用于提高护栏耐腐蚀、减少养护要求的作用，不能很好地减少护栏板硬度，也不能很好地降低传递给车辆的冲撞能量。 "Steel-plastic composite" is another solution. For example, the Chinese patent "Composite road guardrail and its production method" with the publication number CN1393600A proposes a built-in steel bar or steel mesh, and is molded with a composite of unsaturated resin, auxiliary material and glass cloth layer. The Chinese patent "Road guardrail member" with the publication number CN2644499A proposes to cover the surface of the composite extruded polymer material layer on the surface of the corrugated guardrail plate formed by cold bending of the steel plate or strip. In the above-mentioned steel-plastic composite material barrier scheme, molding The composite method cannot be continuously produced, resulting in low production efficiency; the surface of the corrugated steel guardrail is extruded, and the process is complicated to increase the cost. More importantly, there is a problem of compatibility between plastic steel in the existing plastic steel guardrail products. The peeling strength between plastic steel is low, and it is easy to separate due to plastic steel during use and installation, so that its strength and toughness are insufficient. It is not easy to use and is prone to breakage; and the shrinkage coefficient of plastic steel expansion and contraction is different. After the thermal expansion and contraction between plastic steel, there will be relative slip between the two materials, so that there is a gap between the two joints, which will lead to wetness. The gas enters the corroded steel from the breakage of the surface of the material along the gap of the joint surface, reducing the service life of the guardrail and causing safety hazards. Moreover, the above-mentioned plastic steel guardrails are all hard guardrails, or the plastic steel is easy to be separated and cannot be wound up and bent, which causes inconvenience in transportation and storage, and because the length of the guardrail board is limited, many accessories are required for installation, which makes the installation complicated. Moreover, the above-mentioned plastic steel guardrail is mainly composed of intermediate steel structural materials, and the external composite plastic is only used to improve the corrosion resistance of the guardrail and reduce the maintenance requirement, and the hardness of the guardrail is not well reduced, and the transmission is not well reduced. Give the vehicle a collision energy.

本发明采用在梁板的一侧板面上设置多个与梁板一体结构的第一肋板，相邻两个第一肋板之间设有将两个第一肋板连接起来的第二肋板，所述第二肋板与第一肋板、梁板围蔽出中空腔体；第一肋板和第二肋板面向车道，由于第一肋板和第二肋板突出梁板，在车辆发生碰撞后，首先会接触到第一肋板和第二肋板，碰撞后第一肋板的倒伏和第二肋板形成的中空结构能减缓失控车辆所受到的撞击力，延长车辆与护栏的接触时间，降低冲击峰值。然后第一肋板和第二肋板倒伏叠加为梁板的弯曲、拉伸提供足够强度。同时第一肋板是热塑复合板，热塑性复合板包括增强骨架和增强骨架外包覆的热塑材料层，增强骨架具有相当的刚性和强度，热塑材料层具有柔韧性，抗冲击并且无破碎，因此制成的热塑复合板具有相当的刚性和一定的柔韧性，热塑复合板的柔韧性和刚性在一个产品中创造性地在冲撞保护过程的不同阶段分别发挥其作用。 The invention adopts a plurality of first ribs integrally formed with the beam plate on one side of the beam plate, and a second connecting the two first ribs between the adjacent two first ribs a rib, the second rib and the first rib and the beam plate enclose the hollow cavity; the first rib and the second rib face the lane, and the first rib and the second rib protrude from the beam, After the collision of the vehicle, first contact with the first rib and the second rib, the collapse of the first rib after the collision and the hollow structure formed by the second rib can slow the impact force of the uncontrolled vehicle, and extend the vehicle and The contact time of the guardrail reduces the impact peak. The first rib and the second rib are then stacked to provide sufficient strength for bending and stretching of the beam. At the same time, the first rib is a thermoplastic composite board, and the thermoplastic composite board comprises a layer of thermoplastic material reinforcing the skeleton and reinforcing the outer coating of the skeleton, the reinforcing skeleton has considerable rigidity and strength, and the thermoplastic material layer has flexibility, impact resistance and no Broken, the resulting thermoplastic composite panel has considerable rigidity and flexibility, and the flexibility and rigidity of the thermoplastic composite panel play a role in a product at different stages of the collision protection process.

在冲撞过程的初始阶段，由于第一肋板的热塑材料层较好的抗冲击柔性，在车辆撞击中，多个第一肋板倒伏、形成中空腔体的多层第二肋板逐次定向断裂或 /和顺势逐步变形，均能延长车辆与护栏的接触时间，降低冲击峰值，减缓了失控车辆所受到的撞击力，并且第一肋板热塑材料层的柔韧性和顺势逐步变形倒伏，在冲撞过程的变形阶段，倒伏的增强骨架以板簧的形式叠加在梁板上，能够避免护栏破碎及其零部件刺穿车体，危及乘员。提高了迎向车辆撞击的表面整体强度，增强骨架倒伏叠加的板簧结构加上其中热塑材料层的阻尼作用，使得整个护栏具有缓冲减震功能，能够防止车辆穿越护栏或倾覆于护栏上。在整个冲撞过程的结束阶段，由于热塑材料的表面摩擦系数较小，并结合倒伏的第一肋板和第二肋板以板簧结构提供较高强度和减震功能，以及本发明的护栏板的梁板、第一肋板和第二肋板沿护栏板的长度方向延伸能长距离无间断敷设，安装孔处的连接螺栓头高度低于倒伏层叠的第一肋板和第二肋板的设计高度，有利于失控车辆以较小的角度沿护栏无阻碍顺势导出，对车辆运动轨迹进行校正，让其回到行驶车道。 In the initial stage of the collision process, due to the better impact resistance of the thermoplastic material layer of the first rib, in the impact of the vehicle, the plurality of first ribs are laid down, and the plurality of second ribs forming the hollow body are successively oriented. The rupture or/and the gradual deformation of the homeopath can extend the contact time between the vehicle and the guardrail, reduce the impact peak, slow down the impact force of the uncontrolled vehicle, and the flexibility and homeopath of the first rib thermoplastic layer gradually deform. During the deformation phase of the collision process, the reinforced reinforcing frame is superimposed on the beam plate in the form of a leaf spring, which can avoid the broken fence and its parts piercing the vehicle body, endangering the occupant. The overall strength of the surface facing the impact of the vehicle is increased, and the leaf spring structure of the skeleton collapse is added to the damping effect of the thermoplastic material layer, so that the entire guardrail has a cushioning and shock absorbing function, which can prevent the vehicle from crossing the guardrail or overturning the guardrail. At the end of the entire collision process, the surface friction coefficient of the thermoplastic material is small, and the first rib and the second rib combined with the lodging provide a higher strength and shock absorbing function in the leaf spring structure, and the guardrail of the present invention. The beam plate, the first rib plate and the second rib plate of the plate extend along the length direction of the guardrail plate so as to be laid without any distance, and the height of the joint bolt head at the mounting hole is lower than that of the first rib plate and the second rib plate stacked The design height facilitates the out-of-control vehicle to be exported at a small angle along the barrier without hindrance, correcting the vehicle's trajectory and returning it to the driving lane.

本发明护栏板中，梁板采用热塑材料板或热塑复合板，第一肋板采用热塑复合板制成，护栏板的整体具有相当的强度和刚性，也具有一定的柔韧性，可连续生产出长度很长不间断的护栏板，并且护栏板能收卷成卷以便于运输和做到任意长度的长距离敷设。本发明的中空护栏板不仅提高护栏的安全性，还能提高护栏的安装效率；长距离一次性敷设还减少了护栏板连接件，节约成本。并且对失控车辆撞损的护栏板则可现场切断、更换，切断处的裸露金属包覆防腐，并用连接件垫衬和连接。本发明中空护栏板柔性适中，还方便道路弯曲处的护栏设置和安装。附图说明 In the guardrail panel of the invention, the beam plate is made of a thermoplastic material plate or a thermoplastic composite plate, and the first rib plate is made of a thermoplastic composite plate, and the whole of the guardrail plate has considerable strength and rigidity, and also has certain flexibility. Continuously produce long and uninterrupted guardrails, and the guardrails can be wound into rolls for transport and long-distance laying of any length. The hollow guardrail board of the invention not only improves the safety of the guardrail, but also improves the installation efficiency of the guardrail; the long-distance one-time laying also reduces the guardrail joint and saves cost. And the guardrail board that is damaged by the out-of-control vehicle can be cut off and replaced on the spot, and the exposed metal of the cut-off part is covered with anti-corrosion, and is lined and connected with the connecting piece. The hollow guardrail panel of the invention is moderately flexible, and is also convenient for setting and installing the guardrail at the road bend. DRAWINGS

所述防护层 1为复合在缓冲层外且具有抗老化性能的高分子材料制成。防护层 1主要作用是对内层材料的防护，优先解决是整个护栏板最外层材料易老化、磨损的问题，因此需选用柔韧、耐磨损的基础树脂材料，在基础树脂材料中添加抗氧化剂、光稳定剂等抗老化材料，还可以添加抗菌剂、纳米自洁材料保持其卫生清洁，还可以添加提高刚度及耐磨性的辅料。防护层 1 的材料中还包含美观醒目的配色、以及光致发光材料。需要时，防护层 1 也可包含增强材料表面可印刷性的材料。防护层的厚度一般不厚，在 0.5~lmm即可。热塑材料板选用只有缓冲层的单层结构时，主要用于不外露的位置，例如多层连接筋中，被封闭到最外层连接筋和梁板 100之间的连接筋就可以不采用防护层，只需要缓冲。另外，单层的缓冲层中可以添加一些抗氧化、耐磨材料，使其本身也具有抗老化和耐磨的性质。 The protective layer 1 is made of a polymer material which is composited outside the buffer layer and has anti-aging properties. The main function of the protective layer 1 is to protect the inner layer material. The priority is to solve the problem that the outermost material of the whole guardrail board is easy to age and wear. Therefore, it is necessary to use a flexible and wear-resistant base resin material, and add anti-resistance to the base resin material. Anti-aging materials such as oxidants and light stabilizers can also be added with antibacterial agents and nano self-cleaning materials to keep them clean and hygienic. It is also possible to add auxiliary materials for improving rigidity and wear resistance. The material of the protective layer 1 also contains a beautiful and eye-catching color matching, as well as a photoluminescent material. If desired, the protective layer 1 may also contain materials that enhance the printability of the surface of the material. The thickness of the protective layer is generally not thick, and it can be 0.5~1mm. When the thermoplastic material board adopts a single layer structure with only a buffer layer, it is mainly used for a position that is not exposed, for example, in a multi-layer connecting rib, the connecting ribs that are closed between the outermost connecting rib and the beam plate 100 may not be used. The protective layer only needs to be buffered. In addition, some anti-oxidation and wear-resistant materials can be added to the buffer layer of the single layer, so that it also has anti-aging and wear-resistant properties.
