Abstract
A core model of a reserved hole comprises a handle (1), a steel sleeve (2) and an internal positioning reinforcing bar (3); the internal positioning reinforcing bar (3) is arranged in the axis of the steel sleeve (2), one end of the internal positioning reinforcing bar extends out from the undersurface of the steel sleeve (2), and two ends of the handle (1) are connected with the circumference edges of an upper panel of the steel sleeve (2). When the floorslab module is set, the internal positioning reinforcing bar (3) is aligned to the central position of the reserved hole opening, a template is penetrated through the positioning reinforcing bar to arrange the core model of the reserved hole on the template, so that the movement of the core template is avoided when the concrete is poured and vibrated. The core template of the reserved hole has the advantages of being convenient to install and remove, free of special fixing processing, regular in hole forming after being removed and free of damaging of concrete floorslab around the hole opening.
