Device and method for adjusting thickness of steel bar protective layer

Abstract

The invention relates to a device and a method for adjusting the thickness of a steel bar protective layer. The device for adjusting the thickness of the steel bar protective layer comprises an upper cushion block, a lower cushion block and supporting legs connected to the lower cushion block through connecting rods, wherein the upper cushion block is provided with at least three upper steel bar supporting long holes and upper steel bar containing openings corresponding to the upper steel bar supporting long holes; the lower cushion block is provided with corresponding lower steel bar supporting long holes and lower steel bar containing openings corresponding to the lower steel bar supporting long holes; the distance between the top face of the upper cushion block and the bottom faces of the supporting legs is the thickness of a floor needing to be constructed; in any two upper steel bar supporting long holes and any two lower steel bar supporting long holes, the distance between the tops of the upper steel bar supporting long holes and the top face of the upper cushion block is equal to the thickness of an upper steel bar protective layer, and the distance between the bottoms of the lower steel bar supporting long holes and the bottom faces of the supporting legs is equal to the thickness of a lower steel bar protective layer; and floors with different thicknesses of upper steel bar protective layers and lower steel bar protective layers can be constructed, and the application range is widened.

Description

technical field [0001] The invention relates to a device and method for adjusting the thickness of a steel bar protective layer. Background technique [0002] In construction engineering, in order to strengthen the strength of the concrete slab, usually before pouring the concrete, the binding steel bars are made in advance as the skeleton of the concrete slab, and then the concrete is poured to wrap the steel skeleton in the concrete slab. China's "Code for Design of Concrete Structures" (GB50010-2010) stipulates that the thickness of the concrete reinforcement cover is calculated based on the outer edge of the outermost reinforcement (including stirrups, structural reinforcement, distribution reinforcement, etc.). In order to make the prepared concrete slab meet the thickness of the concrete reinforcement cover required by the specification, it is necessary to support and position the reinforcement skeleton before pouring. [0003] In actual construction, pads are usually...
