Abstract

The invention relates to a thickness control device for cast-in-place concrete floor slabs and steel bar protective layers. According to the technical scheme, the thickness control device is characterized by comprising an adjustable barrel and a fixed base, the upper end of the adjustable barrel is used for supporting upper-layer steel bar joints, the lower end of the adjustable barrel is in threaded connection with the upper end of the fixed base, a notch is transversely formed in the lower section of the fixed base, and the lower edge of the notch is used for supporting lower-layer steel barjoints. The thickness control device has the advantages of being suitable for the floor slabs with different thicknesses and having strong popularization.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a device for controlling the thickness of a cast-in-place concrete floor slab and a protective layer of steel bars. Background technique [0002] At present, cast-in-place concrete floor slabs are common in the field of construction. The thickness of the floor slab and the thickness of the upper and lower reinforcement protection layers directly affect the structural safety, durability and crack generation of the building. [0003] The existing Chinese invention patent with application number 201710934562.7 can be referred to, which discloses a cast-in-place concrete floor thickness controller, including a fixing seat, a support rod, and a top panel, and the fixing seat is fixed to the cast-in-place concrete floor formwork by self-tapping screws On the top, the two ends of the support rod are fixedly connected to the fixing seat and the top panel respectively. [0004] Th...
