GJZ矩形坡形桥梁橡胶支座-厂家

矩形坡形桥梁橡胶支座是将矩形支座的层中间钢板改为楔形钢板,其中楔形钢板的坡度分别为:A-1.5%,B-2.0%,C-2.5%,D-3.0%,E-3.5%.其支座坡形与楔形钢板一致.坡形橡胶支座克服了球冠支座和一般坡形支座使用时受力不均,容易脱空的缺点,提高了使用安全性.而且,它用于坡度大于10%的预制简支桥梁除具有一般板式支座的性能外,还有构造简单,安装方便,在桥底不需要再设调坡楔形板\节约投资等优点.

Rectangle sloping bridge rubber bearing is the first intermediate plate rectangular bearings to wedge plate, the wedge plate slope respectively: A-1.5%, B-2.0%, C-2.5%, D-3.0%, E-3.5%. and the support plate. The slope wedge slope shape spherical bearings and rubber bearings to overcome the general slope when using the force bearing are easy to void defects, improve the use security. Moreover, it is used for slope more than 10% prefabricated bridges with the general performance of the bearing plate, and has the advantages of simple structure, convenient installation, in the bottom of the bridge do not need to set the advantage of slope wedge, saving investment and so on.

板式橡胶支座与支座垫石安装,一检查橡胶支座垫石的强度（应符合设计要求）、顶面高程（±2mm和顶面四角高差1mm）、轴线偏位（5mm）、断面尺寸（±5mm），在平坡情况下同一片梁两端支承垫石水平面应尽量处于同一平面内，其相对误差不超过3mm，避免支座发生偏歪、不均匀受力和脱空现象；第二检查橡胶支座垫石的外观质量不得出现漏筋、空洞、蜂窝麻面现象及任何裂缝。第三安装橡胶支座钱，检查支座的外观质量、长、宽、厚和产品合格证书，不符合要求不得使用。

Laminated rubber bearing and bearing pad stone installation, first check the rubber bearing pad stone strength (should comply with the design requirements, the top elevation of (+) 2mm and top four angle elevation 1mm), axis (5mm) and section size (+ 5mm), in the flat slope with a beam supported at both ends of the pad the stone level should be in the same plane, the relative error is less than 3mm, to avoid bearing skew, uneven stress and void phenomenon; check the appearance quality of second rubber bearing pad stone shall drain rib, voids, honeycomb and any crack phenomenon. Third install rubber bearing money, check the bearing appearance quality, length, width, thickness and product qualification certificate, do not meet the requirements, shall not use.

第四安装橡胶支座,先将支座垫石处清理干净一定要垫石处平整。将设计图上标明的支座中心位置在支座垫石及橡胶制作商，橡胶支座准确安放在支承垫石上，要求和支座垫石中心线重合。对于板式支座高程和支座中心与主梁的中心线偏位（2mm之内）、支座顺桥向偏位（10mm之内）和支座四角高差。清理橡胶支座周围杂物，进行梁板的安装基本就完事了。

Fourth, install rubber bearings, first support pad stone clean up, must ensure that the stone pad formation. The design is marked on the seat in the center of the bearing pad stone and rubber producers, rubber bearings accurately placed on bearing pad stones, and bearing pad stone line. For the elevation of the plate support and the center line of the bearing center and the main beam (within 2mm), the abutment deviation of the abutment (10mm) and the elevation of the four angles of the support. Clear the rubber bearings around the debris, the beam board installation, basically finished.

坡形橡胶支座的构造特点在使用坡形橡胶支座时,要当梁体纵坡I>1%时使用，一般板式橡胶支座安装时，须在梁底与支座之间设置与桥梁坡度一致的楔形钢板（或楔形混凝土垫块），以保持支座平置。但该施工方法工艺复杂、费工费料。为设计及施工便利，我们研制生产了坡形橡胶支座时，它是在普通矩形、圆形板式及球冠圆板式支座或其四氟滑板式支座上表面加设了同桥梁坡度相一致的楔形构造，该楔形部分同支座本体是经一次模压硫化而成的整体。

The slope of rubber bearing structural features in the use of sloping rubber bearings, to use when the beam Tizong slope I>1%, general rubber bearing installation, must be at the end of the beam is consistent with the slope of the wedge plate and the bridge between the bearing (or wedge concrete pad), to keep the bearing flat. But the construction method of complex, labour and material consuming. For the design and construction of facilities, we developed a slope shaped rubber bearings, it is in the ordinary rectangular wedge structure, circular plate and circular plate type spherical bearings or PTFE slide on the bearing surface of the bridge with the addition of the slope is consistent, the wedge body with the bearing is integrally formed by a molded vulcanized the.

桥梁支座在桥梁结构中起着承上启下的作用,它既要将作用于桥梁上部结构的全部荷载传递到墩台上,又要作用于桥跨结构的水平力按设计要求合理地分配到墩台上,使桥梁结构的实际受力情况与设计计算时的图式相符。对于工程设计单位,如果支座在设计时若采用的设计参数不合理、选用的支座型式及结构不合理,会给使用中的桥梁结构带来很大的附加应力和变形,不能满足结构受力、变形的需要,还会直接影响桥梁结构的安全及使用。任何一种新型橡胶支座的出现,都必须经过大量试验取得确切数据后确定有关的设计参数,以指导设计人员正确地选用合适的产品。

Bridge support plays a vital role in the structure of the bridge, it will be applied to the whole load of the upper structure of the bridge pier to transfer, but also to ensure the horizontal force acting on the bridge structure according to the design requirements of reasonable distribution to the pier, the actual bridge structure calculation and design of the force schema. For the engineering design, if the design parameters in the bearing when the design is not reasonable, and the selection of the types of support structure is not reasonable, will give the bridge structure in the use of additional great stress and deformation, can not meet the needs of structural stress and deformation, but also directly affect the safety and service life of bridge structure. The appearance of any kind of new rubber bearing has to be tested by a lot of experiments. After obtaining the exact data, the relevant design parameters should be determined to guide the designers to correctly select the appropriate products.

随着板式橡胶支座在桥梁上的广泛应用，其产品重要性也日益受到重视。因此我们对支座的选用、布置、设计计算等方面进行了科学技术分析，目的就是让用户得到更好的产品。为此本着让用户放心精神,我们定期对坡形支座做了抗压试验和橡胶硬度试验，在试验的基础上根据橡胶材料特性和橡胶支座行为特征基本理论，建立FEA模型，并对支座在轴心均布加载工况进行应力分析，结合支座抗压试验变形数据和支座内部应力分布规律证明该FEA模型基本正确，由计算结果可以看出在支座内部存在着应力分布不均匀的现象，同时还可看出坡形橡胶支座的圆周橡胶保护层具有减小支座内部剪应力的作用。

With the extensive application of plate rubber bearings on bridges, the importance of their products has been paid more and more attention. Therefore, we have carried on the science and technology analysis to the bearing selection, the arrangement, the design computation and so on. The purpose is to let the user obtain the better product. In this spirit let users rest assured, we regularly do support slope compression test and rubber hardness test, on the basis of the test according to the basic theory of rubber material and rubber bearing behavior, the establishment of FEA model, and the bearing in axial load conditions for stress analysis, combined with the support of compressive deformation test of internal data support and stress distribution show that the FEA model is basically correct, the results show that stress is uneven distribution in the inner support at the same time, we can also see the circular rubber slope shape rubber bearing protective layer can reduce the bearing internal shear stress.
