一种建筑用混凝土叠合板A kind of concrete laminated board for building

技术领域technical field

本发明涉及一种建筑用混凝土叠合板，特别涉及一种建筑用混凝土叠合板。The invention relates to a concrete laminated board for construction, in particular to a concrete laminated board for construction.

背景技术Background technique

叠合板又称为叠合楼板，叠合板是预制和现浇混凝土相结合的一种较好结构形式。预制预应力薄板与上部现浇混凝土层结合成为一个整体，共同工作，薄板的预应力主筋即是叠合楼板的主筋。预应力薄板用作现浇混凝土层的底模，不必为现浇层支撑模板，薄板底面光滑平整，板缝经处理后，顶棚可以不再抹灰。这种叠合楼板具有现浇楼板的整体性、刚度大、抗裂性好、节约模板等优点。Laminated slabs, also known as laminated floor slabs, are a better structural form combining prefabricated and cast-in-place concrete. The prefabricated prestressed sheet and the upper cast-in-place concrete layer are combined into a whole and work together. The prestressed main reinforcement of the sheet is the main reinforcement of the superimposed floor slab. The prestressed sheet is used as the bottom form of the cast-in-place concrete layer, and it is not necessary to support the formwork for the cast-in-place layer. This kind of superimposed floor has the advantages of integrity, high rigidity, good crack resistance and saving formwork of cast-in-place floor.

常用的叠合板在板与板之间的连接时，往往采用很简单的预制钢筋相互麻花拧紧的方式进行固定连接，但是在使用的过程中发现该种结构由于连接力不强，且在混凝土现浇时，不能很好的与混凝土相结合，其性能往往被制约。When the commonly used laminated board is connected between the board and the board, a very simple way of twisting and tightening the prefabricated steel bars is often used for fixed connection. When pouring, it cannot be well combined with concrete, and its performance is often restricted.

公开号为CN108691381A的中国发明专利一种新型建筑用叠合楼板，其连接时仅仅采用带有螺栓孔的紧固板进行固定，其结构过于简单，连接不够牢靠。使用性能不佳。The Chinese invention patent with the publication number CN108691381A is a new type of laminated floor slab for building, which is only fixed by fastening plates with bolt holes during connection, and its structure is too simple and the connection is not reliable enough. Poor performance.
