1.说明: 由法国STup公司Seridalle工厂生产的叠合板工艺分两个部分: 一部分是工厂预制的预应力薄板。一部分是现浇混凝土层,其厚度根据板跨度而定。用这种方式组合的板是整体式的。预应力板粗糙的上部表面使它与现浇混凝土之间可以有极好的粘结足以承受出现在这一截面的剪应力,由法国建筑工艺的审批部门(建筑科学技术中心)批准了这项制作方法。该板的最大宽度是2.40米,这一尺寸使横向钢筋的用量减至最低限度,同时也遵守了公路运输车辆平行行车的空间间距规定。
1. Description: The lamination process produced by the STidal company’s Seridalle factory in France consists of two parts: One is a factory-prefabricated prestressed sheet. One part is a cast-in-place concrete layer, the thickness of which depends on the span of the slab. The boards combined in this way are monolithic. The rough upper surface of the prestressed slab allows it to have an excellent bond with the cast-in-place concrete sufficient to withstand the shear stress that occurs in this section. This was approved by the Approval Department of the French Building Process (Building Science and Technology Center). Production Method. The maximum width of the panel is 2.40 meters, which minimizes the use of transverse reinforcement and also complies with the spatial spacing requirement for parallel transport of road transport vehicles.
