Nut, is equipped with gasket between the nut and the upper cover plate, the lower cover, the screw rod is located at the set of the part in preformed hole
Equipped with casing, the height of described sleeve pipe and preformed hole it is highly consistent.
Preferably, the upper cover plate is the sector for offering reserved concrete pouring hole, the lower cover be with
The consistent circle of the upper cover board diameter.
Preferably, described sleeve pipe is pvc pipe.
Preferably, the outer diameter of the gasket is more than the aperture of the circular hole, and the internal diameter of the gasket is equal to described
The aperture of circular hole.
Preferably, the upper cover plate, the lower cover and the gasket are steel material.
Using the floor slab preformed hole tool-typed formwork support construction of above-mentioned technical proposal, there are following advantages：Upper cover plate is under
Cover board can realize the closure to preformed hole upper and lower side, and set reserved concrete pouring hole is penetrated through with preformed hole on upper cover plate,
It can realize the casting concrete into preformed hole；Upper cover plate and lower cover are pressed on preformed hole by the both ends of screw rod by nut
Upper and lower side ensure that and be poured to preformed hole inner sealing, be convenient for concrete formation and the integrality to preformed hole closure；Due to spiral shell
PVC casings are arranged with outside bar, the taking-up of screw rod can be facilitated after blocking operation and completing, casing is filled by foaming agent later
The both ends of hole, casing are blocked with anti-crack and anti-seepage mortar, just complete the closure work of entire preformed hole, this structure design is closed
Reason, construction method is simple, and monolithic concrete intensity can be ensured to the closure of preformed hole.
