Description
技术领域 本实用新型涉及一种城市雨水井的井盖。Technical Field The utility model relates to a well cover for urban rainwater wells.
背景技术 目前，城市雨水井上兼有排水和防护功能的井盖，俗称雨水井箅子，其大多数是上面设有条形通孔的长方体铸铁板块，由于其有回收价值，因此被盗现象特别严重。于是人们设计出钢筋水泥及塑料雨水井箅子。但它们并不适用，主要的不足之处是：钢筋水泥井箅子内部仍有金属，因而仍存在被盗窃的问题，同时由于强度不够，常出现“掉角”现象：塑料材质自身强度低，如果要达到与铸铁载荷相同时，其厚度需增加一倍，且同等规格尺寸的开孔率要下降50％左右，严重影响排水能力，若要保证排水能力就要加大尺寸，与其配套的雨水井座及雨水井都要相应地更换或改造，这样做工程量太大，所耗费用太高。Background technology At present, the manhole covers with both drainage and protection functions on urban rainwater wells, commonly known as rainwater well grates, are mostly cuboid cast iron plates with strip-shaped through holes on them. Because of their recycling value, theft is particularly serious . So people have designed reinforced concrete and plastic rainwater well grates. But they are not suitable. The main disadvantage is: there is still metal inside the reinforced concrete well grate, so there is still the problem of being stolen. At the same time, due to insufficient strength, the phenomenon of "dropping corners" often occurs: the plastic material itself has low strength, If it is to achieve the same load as cast iron, its thickness needs to be doubled, and the opening rate of the same specification and size must be reduced by about 50%, which seriously affects the drainage capacity. If the drainage capacity is to be ensured, the size must be increased, and the matching rainwater Well seat and rainwater well all will change or transform accordingly, and like this the engineering quantity is too big, and the expended cost is too high.
发明内容 本实用新型的目的在于提供一种形状尺寸、承载能力及强度均与铸铁雨水井箅子等同但不含金属的高强纤维增强复合材料雨水井箅子。SUMMARY OF THE INVENTION The purpose of this utility model is to provide a high-strength fiber-reinforced composite rainwater well grate whose shape, size, bearing capacity and strength are equal to those of cast iron rainwater well grates but do not contain metal.
本实用新型是由骨架和基体组成的，其中骨架为高强纤维束，它是由多根高强纤维集合在一起组成的丝束，而单根的高强纤维可以是碳纤维、硼纤维、芳纶纤维或无碱型玻璃纤维中的一种。上述高强纤维束围绕在在雨水井箅子通孔周围，交叉呈网格并且多层(2-6层)网格迭加构成的长方体框架即为骨架。整个井箅子的骨架为一根高强纤维束。骨架外面设有将其包容并进入丝束内的高强树脂混料基体，两者结合构成长方体形复合材料板块，其上设有通孔。最好该复合材料板块的长宽尺寸及开孔率与现有的铸铁铁雨水井箅子相同。由于本实用新型表面光滑，可根据需要在井箅子的顶面设砂粒固定在基体表面的防滑层。The utility model is composed of a skeleton and a matrix, wherein the skeleton is a high-strength fiber bundle, which is a tow composed of a plurality of high-strength fibers, and a single high-strength fiber can be carbon fiber, boron fiber, aramid fiber or One of the alkali-free glass fibers. The above-mentioned high-strength fiber bundles surround the through holes of the rainwater well grate, and the cuboid frame formed by intersecting grids and multi-layer (2-6 layers) grids superimposed is the skeleton. The skeleton of the whole well grate is a high-strength fiber bundle. A high-strength resin mixed material matrix is provided on the outside of the skeleton to contain it and enter the tow, and the two are combined to form a cuboid composite material plate, and a through hole is arranged on it. Preferably, the length, width and opening ratio of the composite material plate are the same as those of the existing cast iron rainwater well grate. Because the utility model has a smooth surface, the top surface of the well grate can be provided with an anti-skid layer that sand particles are fixed on the surface of the substrate as required.
本实用新型相比现有技术具有如下优点：1本实用新型内无金属，没有任何回收价值，彻底解决了防盗问题。2本实用新型的外形尺寸及开孔率与铸铁雨水井箅子相同时，其承载能力、强度及排水能力均与铸铁井箅子等同。因此在更换井箅子时不必改动现有的的雨水井及井座的结构。3本实用新型全部为非金属材料，不仅自重轻、成本低、美观、易清洗，而且耐热、耐低温、耐腐蚀、使用寿命长。Compared with the prior art, the utility model has the following advantages: 1. There is no metal in the utility model, and there is no recovery value, which completely solves the anti-theft problem. 2. When the overall size and opening ratio of the utility model are the same as the cast iron rainwater well grate, its bearing capacity, strength and drainage capacity are all equal to the cast iron well grate. Therefore, it is not necessary to change the existing rainwater well and the structure of the well seat when changing the well grate. 3 The utility model is all made of non-metallic materials, not only light in weight, low in cost, beautiful in appearance, easy to clean, but also resistant to heat, low temperature, corrosion and long in service life.
