Manufacturing method of steel bar truss active powder concrete laminated slab
The invention discloses a manufacturing method of a steel bar truss active powder concrete laminated slab. A laminated slab is arranged and composed of a prefabricated bottom plate, a post-cast layer,shear reinforcements and bottom reinforcements; the prefabricated bottom plate and the post-cast layer are formed by pouring active powder concrete, and the bottom steel bars comprise longitudinal stress bars and transverse distribution bars. The method comprises the following steps that binding or welding shear reinforcements and bottom reinforcements is carried out, putting into a mold of the prefabricated bottom plate is carried out, pouring is carried out, naturally curing for 28 days is carried out after mold removal, the cured prefabricated bottom plate is transported to a constructionsite, pouring and curing a post-cast layer are implemented, the material ratio and strength of the post-cast layer is same with the prefabricated bottom plate, assembling is carried out, after the assembly is finished, mold erecting is carried out, secondary pouring and curing are carried out, and then manufacturing of the steel bar truss active powder concrete laminated slab is achieved. The steel bar truss active powder concrete laminated slab has very good anti-bending mechanical properties and rigidity, and is energy-saving, environment-friendly, convenient to produce and good in durability.
本发明公开了一种钢筋桁架活性粉末混凝土叠合板的制作方法。设置一种叠合板，该叠合板由预制底板、后浇层、抗剪钢筋和底部钢筋构成；预制底板和后浇层由活性粉末混凝土浇筑而成，底部钢筋包含纵向受力筋和横向分布筋。将抗剪钢筋和底部钢筋进行绑扎或焊接，放入预制底板的模中进行浇筑，拆模后进行28天自然养护，然后将养护好的预制底板运至施工现场，实施后浇层的浇筑和养护，后浇层的材料配比和强度同预制底板，进行装配，装配完成后，支模进行二次浇筑和养护，即实现钢筋桁架活性粉末混凝土叠合板的制作。本发明具有非常良好的抗弯力学性能和刚度，且节能环保、便于生产、耐久性好。
