The utility model relates to an adjustable cover to reinforcement controlling means. Including structure reinforcing bar, steel sleeve, concrete cushion block, concrete cushion block connecting reinforcement, concrete cushion block connects in the template, through concrete cushion block connecting reinforcement connection concrete cushion block and structure reinforcing bar, locates to be equipped with steel sleeve at concrete cushion block connecting reinforcement and structure concrete cushion block 0. At the form setting in -process, can adjust concrete cushion block according to actual conditions, guarantee conscientiously that cover to reinforcement and form setting satisfy the designing requirement. Effectively avoid the concrete construction in -process template skew to appear, andthen cause the wrong platform of concrete, hourglass to starch, hang mass defects such as curtain, can effectively reduce or avoid the expense of subsequent processing mass defect.
