Abstract
The utility model discloses a concrete slab preformed hole blocking device which is a pre-buried steel tube which brings convenience to blocking of concrete slab preformed holes. The concrete slab preformed hole blocking device comprises the pre-buried steel tube, a bottom ring, and a blocking plate. The concrete slab preformed hole blocking device improves the quality of later-period backfilled concrete of concrete slab beam construction preformed holes, does not need detachment, and is simple and convenient to machine, install and operate.
Description
Technical field
The utility model is a kind of concrete slab preformed hole plugging device.
Background technology
When concrete plate beam is constructed, reserve some holes for satisfying the normal needs of construction demand, these reserving holes mainly are to lift or be used for form brace to wearing reinforcing for steel wire penetrating.Because preformed hole is the penetrating hole of both ends open, and behind a large amount of concrete plate beam hoisted in position or behind the stripping tie rod, an end opening of hole often is positioned at free face, can't seal during shutoff, can't guarantee the concrete quality of later stage shutoff.
Summary of the invention
The utility model provides a kind of concrete slab preformed hole plugging device, is mainly used in the later stage backfill shutoff of concrete slab preformed hole, has solved the quality problems of present concrete plate beam construction when reserving perforation later stage backfill, has improved quality of concrete.
The purpose of this utility model is achieved in that a kind of concrete slab preformed hole plugging device, comprise embedded steel tube, base ring, shutoff plate, described embedded steel tube is column type hollow thin-wall steel pipe, embedded steel tube one end is welded with base ring, described base ring is an annular steel plate, the base ring external diameter is identical with the embedded steel tube external diameter, and the base ring internal diameter is slightly less than the embedded steel tube internal diameter; The shutoff plate is circular steel plate, and the shutoff board diameter is slightly less than the internal diameter of embedded steel tube but is slightly larger than the internal diameter of base ring.
All right, the shutoff plate can be positioned over by an end of embedded steel tube on the entablature of base ring formation, makes embedded steel tube form two cavitys.
Advantage of the present utility model is, uses above structure, and embedded steel tube one end is provided with base ring, places the shutoff plate on the base ring, has improved the quality when perforation later stage backfill is reserved in the concrete plate beam construction.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model structure drawing of device;
Fig. 2 is that the A-A of Fig. 1 is to view;
Fig. 3 construction schematic diagram of the present utility model.
The specific embodiment
A kind of concrete slab preformed hole plugging device comprises embedded steel tube 1, base ring 2, and described embedded steel tube 1 is column type hollow thin-wall steel pipe, and embedded steel tube 1 one ends are welded with base ring 2.
Base ring 2 is an annular steel plate, and base ring 2 external diameters are identical with embedded steel tube 1 external diameter, and base ring 2 internal diameters are slightly less than embedded steel tube 1 internal diameter.
Operating principle: concrete slab is when construction, the embedded steel tube 1 that is welded with base ring 2 is installed firmly by construction requirement, can carry out concreting, after concrete reaches the length of time, stripping or with the concrete slab hoisted in position, flushing embedded steel tube, shutoff plate 3 is put into from embedded steel tube 1 one ends, shutoff plate 3 drops on the entablature of base ring formation, makes the sealing of embedded steel tube 1 one ends, and can carry out the later stage backfill shutoff of pre-buried hole this moment.
