目前,长线法生产预应力混凝土构件,普遍采用混凝土台面,台面的构造也多采用普通地坪加分格的传统做法.就地坪本身的构造而言这种分格当然是必要的,但是,作为生产构件的台面来说(尤其是生产预应力构件),这种做法则并不理想.台面伸缩缝处构件往往产生裂缝,使不少构件因此而报废,秋冬之交尤为严重.多年来一直没有很好解决.为此,本
At present, long-line production of pre-stressed concrete components generally employs concrete countertops. The structure of the countertops also uses the traditional practice of adding ordinary grids. This division is certainly necessary in terms of the structure of the floor itself, however, As a production component of the table (especially the production of prestressed components), this approach is not ideal. Mesa expansion joints often produce cracks, so that many components are therefore scrapped, especially at the turn of autumn and winter. For many years Not well resolved. For this, this
