Plugging device and plugging method for floor reserved hole

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained below in conjunction with specific embodiments.

[0022] A device for blocking reserved holes in floor slabs, comprising a shaped bracket 1 and a hanging template 2. The hanging template 2 is used to seal the lower part of the hole to prevent leakage when concrete is injected later; the shaped bracket 1 is set in the hole Upper part; such as figure 1 As shown, the shaped support 1 and the hanging template 2 are connected by a connecting rod 3, and both sides of the connecting rod 3 are provided with fasteners 4, and the rotating fastener 4 can fix the shaped support 1 and the hanging template 2. And it is convenient for the disassembly after concrete pouring in the later stage; the fastener 4 is detachably arranged on the outside of the shaping bracket 1 and the hanging form 2 to facilitate the rotation of the fastener 4 from both sides. In this embodiment, the connecting rod 3 is shown as a water-stop screw, the fastener 4 is a nut, and the two sides of the water-stop screw are symmetrically provided with nuts. Such as Figure 4 As shown, the center of the hanging form 2 is provided with a jack, and the jack is matched with a water stop screw to prevent the concrete from flowing out.

[0023] Such as image 3 As shown, the shaped bracket 1 includes a supporting plate 5 and a positioning plate 6. The positioning plate 6 is provided with a through hole in the middle to facilitate the insertion of a water stop screw; the supporting plate 5 is fixedly arranged at the lower part of the positioning plate 6 symmetrically , And the support plate 5 is matched with the walls on both sides of the hole; the water stop screw is connected to the hanging template 2 after passing through the through hole and the socket, and the two nuts on the water stop screw are respectively located on the positioning plate 6 and the hanging template 2. On the outside, it is convenient for the construction personnel to adjust the nuts from the upper and lower sides of the floor slab, and seal the holes by pressing the shaping bracket 1 and the hanging form 2; the width of the positioning plate 6 is smaller than the width of the hole, so that the two sides of the positioning plate 6 Inject concrete on the side.

[0024] The construction process of the present invention is as follows:

[0025] First insert the water stop screw into the middle of the hole, the downstairs personnel align the hole of the hanging template 2 with the water stop screw, and install the hanging template 2 under the hole, while the upstairs personnel install the stereotyped bracket 1 above the hole, and install And tighten the upper and lower two nuts, and fix the whole device on the reserved hole by tightening friction force; then fill the hole with micro-expanded stone concrete higher than the original design mark, tamping in layers, and tamping in the fine stone concrete Wipe the calendered surface before final setting; figure 2 As shown, after the concrete is solidified, the shaped bracket 1, the hanging form 2 and the nut are removed, and the part of the water stop screw exposed to the concrete is cut off, and rust prevention is performed. The removed styling bracket 1, hanging template 2, and nuts can be reused when plugging the next hole.

[0026] In the present invention, the hanging template 2 and the shaped bracket 1 cooperate to position the holes, and the hanging template 2 and the shaped bracket 1 are connected and tightened by the water-stop screw and nut, which can effectively block the reserved holes in the floor. The tool is used for hanging mold construction, which is convenient and quick, has uniform forming effect, good survival quality, can effectively prevent leakage and improve the quality of perception, and is easy to dismantle, can be reused, and save materials and environmental protection.

[0027] The embodiments of the present invention have been described in detail above, but the content is only the preferred embodiments of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equal changes and improvements made in accordance with the scope of the application of the present invention should still fall within the scope of the patent of the present invention.
