Description
技术领域technical field
本发明涉及一种双向叠合楼板，尤其是一种建筑领域中使用的蜂窝孔压型钢板双向叠合楼板。The invention relates to a two-way laminated floor slab, in particular to a two-way laminated floor slab of honeycomb hole profiled steel plate used in the construction field.
背景技术Background technique
叠合楼板具有施工快速、免支模、工厂预制、机械化程度高的特点，同时整体刚度大，抗震性能好，是一种工业化程度较高的楼板形式。Composite floor slab has the characteristics of fast construction, free formwork, factory prefabrication, and high degree of mechanization. At the same time, it has high overall rigidity and good seismic performance. It is a floor form with a high degree of industrialization.
在现有叠合楼板中，主要分为普通平板型预应力混凝土叠合楼板、带肋预应力混凝土叠合楼板以及钢筋桁架叠合楼板。Among the existing laminated floors, they are mainly divided into ordinary flat prestressed concrete laminated floors, ribbed prestressed concrete laminated floors and reinforced truss laminated floors.
普通平板型预应力混凝土叠合楼板，通常预制底板较厚、自重较大，跨度小。跨度较大时设置临时支撑。预制底板多为设置预应力钢筋，制作工艺复杂，且易发生反拱现象。Ordinary flat-plate prestressed concrete laminated floor slabs usually have thicker prefabricated bottom slabs, larger dead weight, and smaller spans. Set up temporary supports when the span is large. Most of the prefabricated bottom slabs are equipped with prestressed steel bars, the manufacturing process is complicated, and the phenomenon of reverse arching is prone to occur.
为解决此问题，多在预制底板上加设几道混凝土肋，即带肋预应力混凝土叠合板，但这种楼板自重仍较大。通过在肋上开洞再布置横向钢筋可形成双向板。但设置预应力的方向和横向布置普通钢筋的方向，两个方向的刚度差异较大，很难达到现浇双向楼板的受力特点，对于楼板的整体抗震不利。且在肋上开孔比较困难。In order to solve this problem, several concrete ribs are usually added to the prefabricated floor, that is, the ribbed prestressed concrete composite slab, but the self-weight of this kind of floor is still relatively large. Two-way slabs can be formed by opening holes in the ribs and arranging transverse reinforcement. However, the direction of setting the prestress and the direction of horizontally arranging ordinary steel bars have a large difference in stiffness between the two directions, and it is difficult to achieve the mechanical characteristics of the cast-in-place two-way floor slab, which is not good for the overall seismic resistance of the floor slab. And it is more difficult to make holes on the ribs.
钢筋桁架楼板在实际应用当中一般跨度较小，若増大跨度，则要求增加桁架高度，导致叠合楼板的厚度较大，整体造价随之增加。Reinforced truss floors generally have a small span in practical applications. If the span is increased, the height of the truss is required to be increased, resulting in a larger thickness of the laminated floor and an increase in the overall cost.
