Anti-crack laminated slab and construction method thereof
The invention relates to an anti-crack laminated slab and a construction method thereof. The anti-crack laminated slab comprises a prefabricated slab, a cast-in-place slab and web member steel bars. The cast-in-place slab is arranged on the prefabricated slab; one end of the web member steel bar is connected with the prefabricated slab, and the other end of the web member steel bar is connected with the cast-in-place slab; the prestressed tendons are embedded in the precast slab and are used for extruding concrete in the precast slab; the prestressed tendon comprises a spiral section and straight sections, the straight sections are arranged on the two sides of the spiral section, and the straight sections and the spiral section are integrally formed; the spiral section is embedded in the prefabricated slab, and gaps for concrete to penetrate through are formed between coils of the spiral section; the straight section is used for being connected with a tensioning device so as to stretch the spiral section. In the application, the prestressed tendons are shrunk to compress concrete in the precast slab, so that the generation of cracks of the precast slab is reduced; therefore, the anti-cracking performance of the laminated slab in the production, transportation and hoisting processes is improved, the on-site acceptance qualification rate of the laminated slab is improved, and the project progress is guaranteed.
本申请涉及一种抗裂叠合板及其施工方法，包括预制板、现浇板、腹杆钢筋；现浇板设置于预制板上；腹杆钢筋一端与预制板相连接，腹杆钢筋的另一端与现浇板相连接；还包括若干个预应力筋，预应力筋埋设于预制板中，预应力筋用于挤压预制板中的混凝土；预应力筋包括螺旋段和平直段，平直段设置于螺旋段两侧，平直段与螺旋段一体成型；螺旋段埋设于预制板中，且螺旋段的线圈之间设有供混凝土穿设的间隙；平直段用于与张拉装置相连接，以拉伸螺旋段。在本申请中，预应力筋收缩以压缩预制板中的混凝土，以减少预制板裂缝的产生；从而显示提高叠合板在生产、运输、吊装过程中的抗裂性能，提高叠合板现场验收合格率，以保证项目进度。
