The supporting part support by plastics ball and base and constitute, the base supports and is three, three bases support slope and circumference equipartition at the surface of plastics ball to form triangle bearing structure.
The upper surface of the plastic hemisphere is provided with a positioning hole, and a floor thickness control piece is inserted into the positioning hole.
The four positioning holes are uniformly distributed on the upper surface of the plastic hemisphere; the floor thickness control piece is structurally characterized in that four steel bars are connected with aluminum sheets together, and each steel bar is vertically inserted into a positioning hole.
The method for supporting the steel bar protective layer by adopting the adjustable steel bar supporting device comprises the following steps:
1) screwing the screw rod into the plastic ball, and adjusting the height to ensure that the distance between the top surface and the bottom surface of the plastic hemisphere is the height of the reinforcing steel bar protection layer;
2) placing a plurality of reinforcing steel bar supporting devices on the template at equal intervals, adjusting the angle of the plastic hemisphere, and then respectively placing the transverse and longitudinal floor slab reinforcing steel bars into the cross grooves, so that the floor slab reinforcing steel bars are ensured to be in the same horizontal plane;
3) and then carrying out normal construction of concrete.
If the thickness of the floor slab has technical requirements, the floor slab thickness control piece is inserted into the positioning hole, the distance between the aluminum sheet and the bottom template is equal and equal to the thickness of the floor slab, then concrete is poured, and the upper surface of the concrete and the aluminum sheet are on the same horizontal plane, namely the control construction of the thickness of the floor slab is ensured.
This reinforcing bar strutting arrangement with adjustable uses the plastic ball as the main part, and three base supports and is connected with the plastic ball and constitutes the triangular supports, forms reinforcing bar strutting arrangement, and this kind of strutting arrangement has great compressive capacity, and accessible wrench movement connects spheroid and top hemisphere to come control screw rod to expose length to control whole strutting arrangement height, the thickness of control reinforcing bar protective layer in the concrete of different thickness.
