Description
Technical field
The utility model relates to a kind of construction tool for building, is specifically related to a kind of floor sewer pipe preformed hole and exempts from form removal tool.
Background technology
Conveniently install in the different floors of building and supply water and drainage pipe, usually need reserving installation hole in constructure construction procedure.Conventional preformed hole construction method adopts tub to be fixed on floor cast template, and then carry out pouring concrete, in concrete placement, may due to the insufficient strength of tub own, hole is caused to occur the situation of distortion, and in order to take out tub, usually tub is needed to have certain tapering, tapering usually causes tub to bear larger buoyancy when fluid concrete, floating or even position that tub very easily occurs are moved, the position of pore-forming and shape is caused to change, the such mould of tub is finally adopted also to need extra operation to remove, time-consumingly to require great effort again, and in demolishing process, likely destroy tub or preformed hole itself, bring extra trouble, finally because the preformed hole after shaping is concordant with flooring, when after installation sewer pipe, the water electrode of floor easily drains to along preformed hole in the family of resident family of lower floor.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of intensity is large, anti-floating power, water-tight, and do not need the floor sewer pipe preformed hole removed to exempt from form removal tool.
In order to solve the problems of the technologies described above, the utility model provides a kind of floor sewer pipe preformed hole to exempt from form removal tool, comprise the cylindrical die be vertically placed on floor cast template, this cylindrical die is by concrete prefabricated shaping, it is highly greater than slab thickness, the bottom outside of cylindrical die is provided with a circle and seals with floor cast template the bulge loop contacted, the inner side of cylindrical die is provided with the vertical chute be oppositely arranged, the lower end closed of this vertical chute is arranged, brace is provided with between vertical chute, described brace is fixed on the floor cast template of below by screw.
Adopt the floor sewer pipe preformed hole of technique scheme to exempt from form removal tool tool to have the following advantages: because cylindrical die is by concrete prefabricated shaping, therefore not only cost is low, and working (machining) efficiency is high, and possesses larger compressive strength; Cylindrical die is vertically placed on floor cast template, and it is highly greater than slab thickness, and therefore after moulding by casting, the water of flooring can not flow in cylindrical die, more can not bleed in lower floor household; The bottom outside of cylindrical die is provided with a circle and seals with floor cast template the bulge loop contacted, concrete is made to produce downward pressure to bulge loop upper surface, cylindrical die is not only avoided to float, and it is more tight to make cylindrical die be combined with floor cast template, shaping its of fluid concrete becomes an entirety with cylindrical die compact siro spinning technology, without the need to removing, the gap leaked also can not be produced.
Preferably, the top of described cylindrical die is provided with housing, is provided with the projection snapping in vertical chute below described housing, and such arranging can be avoided in the process of fluid concrete, concrete enters into cylindrical die, thus does not affect the demoulding.
Preferably, described vertical chute is relatively set with two, and it is more easy that such arranging can make to install brace in vertical chute.
Preferably, the middle part of described brace is provided with stamping forming tongue, this tongue is arranged along the length direction of brace, like this arrange can the intensity of brace larger, to avoid in the process of tightening screw or to damage in the process of cast and vibrated concrete, and then the installation site accuracy of guarantee cylindrical die.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model embodiment floor sewer pipe preformed hole exempts from form removal tool;
Fig. 2 is the plan structure schematic diagram (not containing housing) that the utility model embodiment floor sewer pipe preformed hole exempts from form removal tool.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Reference numeral in Figure of description comprises, cast template 1, cylindrical die 2, housing 3, bulge loop 4, vertical chute 5, brace 6, screw 7, concrete eight.
As depicted in figs. 1 and 2, the utility model provides a kind of floor sewer pipe preformed hole to exempt from form removal tool, comprise the cylindrical die 2 be vertically placed on floor cast template 1, cylindrical die 2 is by concrete prefabricated shaping, the height of cylindrical die 2 is greater than slab thickness, preferably exceed flooring about 20mm, the top of cylindrical die 2 is provided with housing 3, the bottom outside of cylindrical die 2 is provided with a circle and seals with floor cast template 1 bulge loop 4 contacted, the inner side of cylindrical die 2 is provided with the vertical chute 5 be oppositely arranged, vertical chute 5 is relatively set with two, housing 3 adopts pvc material global formation, the projection snapping in vertical chute 5 is provided with below housing 3, to avoid in the process of fluid concrete, concrete enters into cylindrical die 2, the lower end closed of vertical chute 5 is arranged, brace 6 is provided with between vertical chute 5, brace 6 is fixed on the floor cast template 1 of below by screw 7, the middle part of brace 6 is provided with stamping forming tongue, tongue is arranged along the direction of brace 6 length, to increase the intensity of brace 6, to avoid in the process of tightening screw 7 or to damage in the process of cast and vibrated concrete.
It is work like this that the floor sewer pipe preformed hole of technique scheme exempts from form removal: cylindrical die 2 is by concrete prefabricated shaping, and therefore not only cost is low, and working (machining) efficiency is high, and concrete possesses larger compressive strength, not fragile; Cylindrical die 2 is vertically placed on floor cast template 1, and entirety exceeds flooring design height about 20mm, and therefore the water of flooring all can not flow in cylindrical die 2 in casting process or after moulding by casting, more can not bleed to lower floor; The bottom outside of cylindrical die 2 is provided with a circle and seals with floor cast template 1 bulge loop 4 contacted, bulge loop 4 soffit does not contact with concrete, and upper surface is pressed on floor cast template 1 downwards by concrete, thus avoid cylindrical die 2 to float, after fluid concrete 8 is shaping, can become an entirety with cylindrical die 2 compact siro spinning technology, cylindrical die 2 itself forms preformed hole.
Above-described is only preferred embodiment of the present utility model; should be understood that for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
