Disclosure of Invention
Aiming at the defects in the prior art, the invention provides the adjustable screw for controlling the thickness of the pier stud reinforcement protection layer, after the structure is adopted to operate, the qualification rate of the reinforcement protection layer before and after the construction is high, the construction quality is effectively ensured, in addition, the operation is simple, the cost is lower, and the popularization value is higher.
In order to achieve the aim of the invention, the invention adopts the following technical scheme:
An adjustable screw for controlling the thickness of a pier stud reinforcement protection layer, comprising: a erect supporting rib for enclosing into the steel reinforcement cage, erect the outer circumference welding of supporting rib and wind the muscle outward, erect the interior circumference welding of supporting rib middle part and interior strengthening rib, strengthening rib top welding curved overlap joint muscle, weld the nut between overlap joint muscle and the strengthening rib, nut internal thread connection screw rod, the screw rod stretches into the welding of steel reinforcement cage end and is the short reinforcing bar head of platykurtic, the screw rod exposes the steel reinforcement cage outside end and is the cusp.
Further, the screw rod is retracted into the reinforcement cage before die assembly, the die assembly can be carried out smoothly, deformation and falling caused by collision of the screw rod and the die plate are avoided, the screw rod is manually rotated to eject after die assembly, the extension length of the screw rod is adjusted to meet the thickness requirement of the inner reinforcing rib protective layer, the single section setting interval of the screw rod, namely the arc length of the lap joint rib is 110cm-120 cm, and the section interval is 290 cm-310 cm.
The beneficial effects of the invention are as follows:
The screw cap is welded on the reinforcement cage and is fixed firmly by adopting the lap joint ribs, the screw is sleeved, the short reinforcement heads are welded at the tail parts of the screw side by side and are flat, the screw is convenient to rotate, the outer sides of the screw heads are sharpened, the screw is retracted into the reinforcement cage before die assembly, the die assembly can be carried out smoothly, and deformation and falling caused by collision of the screw and the die plate are avoided; after the die is assembled, the screw rod is manually rotated to eject, and the extension length of the screw rod can be gradually adjusted, so that the requirement of the design of the thickness of the reinforcement protection layer is met. The single section of the screw is provided with the spacing of 110cm-120 cm, the arc length is uniformly distributed, and the spacing of 290 cm-310 cm can meet the requirements. After the operation structure is adopted, the qualification rate of the reinforcement protection layer before and after the thickness is high, the construction quality is effectively ensured, in addition, the operation is simple, the cost is lower, and the popularization value is higher.
