The endoporus aperture of sleeve is more than the outer diameter of screw rod；The block that section is cydariform is fitted in the segmentum laterale inner cavity of special-shaped end to lead
Column, the inner face of block guide post carry and the oblate cylinder wide guide post half slot of mouth up and down.
The utility model is provided with from outer end sleeve between screw rod and cannulated sleeve and length is more than cannulated sleeve endoporus
The cylindricality cushion block of length, the center hub of cylindricality cushion block are the blind hole that diameter is more than outer screw diameter.The section of the cannulated sleeve
Outer surface is octagonal cylinder or hexagon cylinder or cylindrical surface.Being made above screw rod has recessed groove and is carved in recessed groove
It is formed with graduated scale.In cannulated sleeve nozzle and the setting of cylindricality cushion block periphery mutually equipped card slot and convex block.
When the utility model is positioned for reinforced concrete protective layer, by the special-shaped end sleeve of the utility model in steel
On muscle, reinforcing bar is clamped between the half slot of special-shaped end necking down changeover portion and the guide post half slot of block guide post, it will be hollow
Sleeve portion adjusts rear locking positioning nut, and the distance between the outer end face of sleeve and the outer end face of special-shaped end are reinforcing bar
The thickness of concrete layer is clamped two end faces of the utility model by reinforced concrete floor both sides template, is clamped in abnormal shape
Reinforcement location between end necking down changeover portion and block guide post is fixed, and will not be moved.It can ensure that after casting concrete,
Concrete cover to reinforcement thickness is consistent with design requirement, to ensure construction quality.
The utility model stabilized structure is reliable, easy to install and use, can accurately control the coagulation of reinforced concrete member
Protective soil layer thickness improves reinforced concrete structure total quality and function.
