Abstract
The utility model relates to a device used for preformed hole of building conduit, comprising three independent parts like a preformed hole model, a pre-embedded supporting board and a hole sealing eccentricity sealing element, characterized in that the rotating crank of the model is connected with a center positioning lock shaft, and the lower end of the shaft is provided with threads tightly matched with a circular nut. A self-threading bolt is arranged under the threads, and the model is provided with a barrel, having a sealing cover on the top. When using, the pre-embedded supporting board is laid on the model, the external side of the model barrel is sheathed in the positioning baffle of the supporting board, and the rotating crank is rotated to drive the lock shaft and the self-threading bolt to be tightly locked, and then the concrete is poured. After the initial condensation, the crank is back turned to make the model be extracted, and then a hole shape is preformed. The hanging shaft of the supporting board is embedded in the concrete layer to hang the supporting board, making the supporting board be tightly attached to the bottom surface of a concrete floor. The part of the supporting board which is extended into the hole forms a step at the bottom of the hole shape. When installing, the conduit is penetrated through the hole of the supporting board, and then the eccentricity sealing element which is conformed to the pipe diameter is inlaid. The elastic sealing ring of the sealing element is tightly sealed with the external diameter of the pipe. The external eccentricity part can be rotated in 360 degrees to cover the gap formed between the conduit and the inner hole of the supporting board. Then, the concrete can be poured in the hole, the labor and material are saved, and the construction efficiency is improved.
Description
Technical field:
The utility model relates to a kind of floor pipeline preformed hole and forms and secondary hole sealing, belongs to building water supply and drainage pipe installation technology field.
Background technology:
In installing, the building storey water supply and sewerage pipeline have three big technologies comparatively complicated at present, by waiting to improve.One, preformed hole model: when pouring concrete, need on floor, to reserve an eyelet bigger than caliber, pass for pipeline, present way mainly adopts thick batten, follow closely into the square tub by caliber, on template, throw off with template the cast back as the model nail, just form cubic hole, existing model way, more original, take a lot of work, take material, an eyelet needs a model, wastes a large amount of timber.They are two years old, lay template in the floor bottom: water supply and sewerage pipeline passes from reserving eyelet during installation, because pipeline and preformed hole have the gap of very big adjusting deviation, need during sealing of hole lay template once more in the preformed hole bottom, template is fixing adopt pin top, bottom or with iron wire around above floor, hanging, fluid concrete again, this kind method, the expense of not only taking a lot of work material, and template often occurs and cave in, often do over again.They are three years old, permeate behind the sealing of hole: behind the piping erection sealing of hole, because concrete and pipeline external surface can not merge fully, in concrete mummification process, pipeline external surface leaves the shrinkage joint that is invisible to the naked eye, and the user uses several Nian Houchang that phenomenon of osmosis takes place, and national departments concerned is also formulated multinomial standard, such as adopting water blocking ring etc., but can't thoroughly solve infiltration problem.
Summary of the invention:
The purpose of this utility model is that a kind of preformed hole model of design can use repeatedly, and secondary hole sealing need not re-lay template, can not permeate, and significantly improves the building pipe preformed hole application apparatus of operating efficiency.
The technical scheme that the invention for solving the technical problem adopted is: the pipeline preformed hole application apparatus, preformed hole model, pre-buried supporting plate, eccentric sealed three independent sectors of sealing of hole are arranged, and solved the technological problems that preformed hole and piping erection exist respectively.The preformed hole model is by rotary handle, elastic press, cylindrical shell, loam cake, lock shaft, tapping screw, round nut is formed, preformed hole model and supporting plate are simultaneously on the fixed form during use, the boring ratio caliber is big in the supporting plate, external diameter is bigger than preformed hole model, the solid place column of a plurality of threaded shapes that evenly distributes between the external diameter of supporting plate and internal diameter, top has greater than the column conical head, behind the fluid concrete, the column of supporting plate is set in the cement layer, hang supporting plate, extract model out, promptly form a rational eyelet of the proportion of installation, supporting plate stretches out in the hole partly and forms step in the eyelet bottom, pipeline passes from the supporting plate endoporus during installation, because pipeline and supporting plate endoporus leave the gap of certain adjusting deviation, put into eccentric sealed during sealing of hole, eccentric sealed endoporus elastic sealing ring and external diameter of pipe tightening seal, eccentric sealed outer eccentric part, according to pipeline and supporting plate endoporus deviation, rotate eccentric sealed, be adjusted to and the sealing of supporting plate inner pore, need not re-lay template, pouring concrete in the directly past hole, the saving of labor, material-saving.
The beneficial effects of the utility model are, reasonable in design, and model is reusable, and secondary hole sealing need not laid template, has solved concrete and the pipeline enclosure shrinkage joint brings infiltration problem, saves timber, and preformed hole unifies standard, significantly improves operating efficiency.
