不设横向缝的预应力混凝土台座的优点是能增加台座产值和节约钢材。长线台座,除满足工艺要求外,尚应根据生产规模、场地大小、地基条件等合理地进行平面布置以及选用适当的构造方案。台座主要由垫层、基层和面层(台座板块) 组成,为消除现浇面与基层之间胶结力和咬合力,使面层在温度变化的条件下自由伸缩,在基层和面层
The advantage of prestressed concrete pedestal without transverse seams is that it can increase the production value of the pedestal and save the steel. Long-term pedestals, in addition to meeting the process requirements, should be reasonably laid out according to the scale of production, site size, ground conditions, etc., as well as the selection of appropriate construction plans. The pedestal is mainly composed of a cushion layer, a base layer and a surface layer (pedestal plate). In order to eliminate the cementing force and bite force between the in-situ casting surface and the base layer, the surface layer can freely expand and contract under the conditions of temperature change, in the base layer and the surface layer.
