Grouting corrugated steel pipe truss prestressed concrete laminated slab and construction method
The invention discloses a prestressed concrete laminated slab of a grouting corrugated steel pipe truss, which is characterized in that firstly, the thickness of a prefabricated bottom plate is reasonably set to prevent the phenomenon that the prefabricated bottom plate is too thick, so that the dead weight is increased, materials are wasted, the compressive strength is increased, the phenomena of cracking and the like of a floor slab in a stress process are easily caused, and the floor slab is directly broken after being damaged and comprises reinforcing steel bars; secondly, the high-strength grouting steel pipe trusses and the prestressed steel bars are adopted as the plate bottom bars, the bearing capacity of the prefabricated plate can be greatly improved, and the connecting performance of the laminated plate is greatly improved through the special structure of the web member component; and finally, the pre-stressed steel bars are reasonably arranged to completely penetrate through the area of the prefabricated bottom plate to prevent the plate end steel bars from affecting the end beam steel bar binding effect.
本发明公开了一种注浆波纹钢管桁架预应力混凝土叠合板，首先合理设置预制底板的厚度防止预制底板过厚，从而导致自重增加，浪费材料，抗压强度增大，容易导致楼板在受力过程中不易发现开裂等现象，受到破坏而是直接断裂包括钢筋，受力问题变了，导致塌方事故，其次采用高强灌浆钢管桁架和预应力钢筋作为板底筋，可大大提高预制板承载力，并且通过腹杆部件的特殊构造极大的提高叠合板的连接性能，最后合理设置预应力钢筋完全贯穿预制底板的区域防止板端钢筋影响端部梁钢筋绑扎的效果。
