Prefabricated bottom plate of laminated slab and laminated slab
The invention provides a prefabricated bottom plate of a laminated slab and the laminated slab, and belongs to the field of fabricated buildings, and the prefabricated bottom plate is provided with a plurality of rows of inclined line pipe grooves which are arranged in a crossed mode. In addition, at least in the middle area with large bending moments at the two opposite ends in the span direction of the prefabricated bottom plate, grooves in the section, perpendicular to the plate span direction, of the prefabricated bottom plate are not through. Compared with a traditional laminated slab, a steel bar truss (only acting in the construction stage) is omitted, and the steel bar consumption is reduced; compared with a traditional laminated slab, the thickness of most of the floor slab in the scheme is 95 mm (with respect to the slab thickness of 130 mm, the thickness of a protective layer is deducted by 15 mm, and the height of two layers of steel bars is 20 mm), the thickness of the traditional laminated slab is generally 60 mm, and therefore even if a steel bar truss is not needed, the rigidity of the floor slab is far larger than that of the traditional laminated slab, and supporting-free construction of 4 m or above can be achieved; and the support-free span of the traditional laminated slab is only about 2m.
本发明提供一种叠合板的预制底板和叠合板，属于装配式建筑领域，该预制底板上开设有多排交叉布置的斜向线管槽。并且，至少于预制底板跨度方向相对两端弯矩较大的中间区域，预制底板垂直于板跨度方向的截面中槽不贯通。相对于传统叠合板取消了钢筋桁架（仅施工阶段起作用），节省了钢筋用量；且相对于传统叠合板，本方案的楼板大部分厚度均为95mm（相对于130mm的板厚，扣除保护层厚度15mm和两层钢筋高度20mm），而传统叠合板的厚度一般为60mm，因此即使不需要钢筋桁架，本发明的楼板刚度也远大于传统叠合板，可以实现4m以上的免支撑施工，而传统叠合板的免支撑跨度只有2m左右。
