Device and method for controlling thickness of upper reinforcing steel bar protective layer of floor support plate
A device and method for controlling the thickness of an upper steel bar protective layer of a steel bar truss floor support plate are characterized in that the thickness of the steel bar protective layer is controlled by adjusting the height of a truss on a bottom formwork, and the truss is mainly formed by welding an upper chord steel bar (1), a lower chord steel bar (2) and a web member steel bar (3); the bottom template and the truss form a system in a manner of forming a profiled galvanized steel sheet (4), a middle vertical rib (5) and an end folded edge (6); a plurality of truss floor support plates are spliced into a whole, and meanwhile, the truss floor support plates are anchored into an end support concrete structure, so that the truss floor support plates and the concrete structure are effectively combined, the range of a formed top plate is well controlled, internal and external corners are square, and the overall impression effect is remarkable. The method is flexible in application and high in operability, the productivity is not affected after adjustment, the one-time binding qualification rate of on-site steel bars is increased, cost is saved, the bearing capacity of structural floor slabs is not affected, and wide application prospects are achieved.
一种控制钢筋桁架楼承板上层钢筋保护层厚度的装置和方法，其特征在于，包括通过调节底模板上桁架高度实现控制钢筋保护层厚度的步骤，所述桁架主要由上弦钢筋(1)、下弦钢筋(2)和腹杆钢筋(3)通过焊接组成；所述底模板主要由压型镀锌钢板(4)、中部立肋(5)、端部折边(6)的方式与桁架共同组成体系；将若干片桁架楼承板拼装成整体，同时桁架楼承板锚固入端部支座混凝土结构内，以达到桁架楼承板与混凝土结构有效结合，成型后顶板极差控制较好，阴阳角方正，整体观感效果显著。该方法适用灵活，可操作性强，调整后不影响产能，便于现场钢筋一次绑扎合格率，节约成本，不影响结构楼板承载力，具有广阔的应用前景。
