圓形橡膠支座/矩形橡膠支座是橋梁上,下部結構的連接點,其作用是將上部結構的荷載順適,安全地傳遞到橋墩臺上去,同時保證上部結構在荷載,溫度變化,凝土收縮等因素作用下的自由變形,以便使結構的實際受力情況符合計算圖式,并保護梁端,墩臺帽不受損傷.這就要求它具有足夠的豎向剛度和彈性,能將橋梁上部結構的全部荷載可靠地傳遞到墩臺上,并同時承受由荷載作用引起的橋跨結構端部的水平位移

圓形橡膠支座/矩形橡膠支座是橋梁上,下部結構的連接點,其作用是將上部結構的荷載順適,安全地傳遞到橋墩臺上去,同時保證上部結構在荷載,溫度變化,凝土收縮等因素作用下的自由變形,以便使結構的實際受力情況符合計算圖式,并保護梁端,墩臺帽不受損傷.這就要求它具有足夠的豎向剛度和彈性,能將橋梁上部結構的全部荷載可靠地傳遞到墩臺上,并同時承受由荷載作用引起的橋跨結構端部的水平位移,轉角和變形,減輕和緩解橋墩承受的震動,適應因溫度,濕度變化引起的橋跨結構脹縮.
The circular rubber bearing / rectangular rubber bearing is on the bridge, the connection point of lower structure, its function is to load the adaptation of the upper structure, safe transfer to the pier table, while ensuring the temperature change of the upper structure under loads, deformation free, concrete shrinkage effect factors, so that the structure of the actual stress with the calculation of schema, and to protect the end of the beam, pier cap is not damaged. This requires that it has enough vertical stiffness and elasticity, can be the full load of bridge superstructure is reliably transmitted to the pier, and bear the load of horizontal displacement caused by the end of the bridge, and corner deformation, reduce and alleviate the pier bear vibration, due to temperature, humidity changes caused by bridge expansion and contraction.
就圓形橡膠支座/矩形橡膠支座的安裝位置而言,雖然在使用中可以進行圓形橡膠支座/矩形橡膠支座更換,但更換的成本費用,技術性以及困難性均很大,橋梁中大部分圓形橡膠支座/矩形橡膠支座可謂是*性的安裝,圓形橡膠支座/矩形橡膠支座壽命應該與橋梁的壽命相吻合,否則會對橋梁的使用造成不良的后果,盡管在橋梁的成本造價中圓形橡膠支座/矩形橡膠支座成本僅占很小的比例,但作用遠遠超過其成本,為此,圓形橡膠支座/矩形橡膠支座就成為橋梁建設和使用的重要材料之一.
The installation position of the circular rubber bearing / rectangular rubber bearings, although can be used in a circular rubber bearing / rectangular rubber bearing replacement, but the replacement cost, and technical difficulty are great, most of the bridge circular rubber bearing / rectangular rubber support is a permanent installation of rubber bearings / round the life of rectangular rubber bearings and bridge life should be consistent, otherwise it will use to bridge the adverse consequences, in spite of the bridge cost in circular rubber bearing / rectangular rubber bearing costs accounted for only a small proportion, but the effect is far more than its cost, therefore, the circular rubber bearing / rectangular rubber bearing has become one of the an important material in bridge construction and use.
近年來在橋梁圓形橡膠支座/矩形橡膠支座使用過程中,圓形橡膠支座/矩形橡膠支座出現了各種各樣的質量問題和質量隱患,究其原因可分為產品質量,施工質量和設計選型三方面.圓形橡膠支座/矩形橡膠支座支座的產品質量,施工質量和設計選型關系到圓形橡膠支座/矩形橡膠支座的使用壽命,需要生產方,施工方和設計方的緊密配合,任何一方出現問題都將嚴重影響圓形橡膠支座/矩形橡膠支座的使用壽命,
In recent years, the circular rubber bearing bridge / rectangular rubber bearings in the process of using circular rubber bearings / rectangular rubber bearings have quality problems and quality problems of all kinds, the reason can be divided into product quality, construction quality and design and selection of three aspects. The circular rubber bearing / rectangular rubber bearings bearing product quality, construction quality the design and selection of related to the service life of the circular rubber bearing / rectangular rubber bearings, need to work closely with the production side, the construction side and the design side, any problems will seriously affect the service life of the circular rubber bearing / rectangular rubber bearings,
