Abstract
The utility model discloses a pipeline hole mold of a cast-in-situ concrete roof board, which comprises a conical mold body with demolding conicity, wherein the mold body is provided with a central through hole and a thread compression bar; threads are arranged at the lower part of an upright bar of the thread compression bar; a round compression disc is fixed at the upper part of the upright bar of the thread compression bar; a cross bar is fixed at the upper end of the upright bar of the thread compression bar; the upright bar of the thread compression bar passes through the central through hole of the mold body and the lower end of the upright bar extends outside the mold body; the round compression disc of the upright bar of the thread compression bar is compressed on the upper end surface of the mold body; and a handle is arranged at the upper end of the mold body. The pipeline hole mold of the cast-in-situ concrete roof board can be produced in a production line way, has low manufacturing cost and can be used repeatedly; the mold is positioned quickly without mold moving or running; and the mold stripping is convenient and quick, and the reinforced concrete structure of the roof board is not damaged.
Description
Technical field:
The utility model relates to a kind of cast-in-situ concrete Roofing slab pipe hole mould, reserves floor water supply and sewerage pipeline hole when being used for building operations concreting Roofing slab.
Background technology:
Existing cast-in-situ concrete Roofing slab pipe hole mould does not have product to sell on the market, rely on unit in charge of construction to make by hand, mainly is welded by steel pipe, directly scraps after mould is finished using, and can not reuse.When concreting, steel pipe socket mould location is difficult, is prone to and runs the mould phenomenon, and molding difficulty behind steel pipe socket and the concrete bonding often will be beaten with sledgehammer, damages the reinforced concrete structure of floor easily, causes the floor crackle.
Summary of the invention:
The purpose of this utility model provides a kind of cast-in-situ concrete Roofing slab pipe hole mould, realizes cheap, quick location, convenient, the repeatedly used purpose of molding.
The purpose of this utility model realizes as follows: it comprises the conical molds body of a band demoulding tapering, mold has central through hole, a screw thread depression bar is arranged, screw thread is arranged at the vertical rod bottom of screw thread depression bar, circular platen is fixed on the top of the vertical rod of screw thread depression bar, the upper end fixed transverse rod of the vertical rod of screw thread depression bar, the vertical rod of screw thread depression bar pass central through hole and its lower end of mold and stretch out in the mold outside, and the circular platen of the vertical rod of screw thread depression bar is pressed on the mold upper surface.
The mold upper end is provided with handle, and the two ends prolong knot of handle is on the two sides of mold, and the effect of handle is to be used for molding.Also axial location between screw thread depression bar and the mold can be realized the molding action by upwards extracting the screw thread depression bar, thereby can omit handle.
Mold surrounds the outline body by taper side face, loam cake and bottom, connects hollow section between loam cake and the bottom centre bore.
Be filled with blowing agent in the cavity that mold is made of taper side face, loam cake, bottom, hollow section, avoid casing deformation.
The mold bottom is higher than taper side face following peripheral, makes between taper side face and the bottom and forms cavity, avoids die shift, prevents to run mould.
During use, earlier mould is put into reserved location, rotate the screw thread depression bar, screw thread depression bar bottom thread screws in the building plank of laying, fixed after, beginning steel concrete is built, after steel concrete is solidified to a certain degree, the screw thread depression bar is screwed out from the building plank, catch handle then, mould is proposed, finish the reservation task of building floor water supply and sewerage pipeline.
But the production of the utility model streamlined is cheap, can use repeatedly, and mould is located fast, is not shifted, and does not run mould, and molding is convenient and swift, does not damage the reinforced concrete structure of floor.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
With reference to accompanying drawing, the conical molds body 6 that a band demoulding tapering is arranged, mold 6 surrounds the outline body by taper side face, loam cake 3 and bottom, connect hollow section between loam cake 3 and the bottom centre bore, the hollow section endoporus becomes the central through hole of mold, loam cake 3 can be fixed with screw and taper side face, gains in strength for tower structure thicker around loam cake 3 center holes.Be filled with blowing agent 5 in the cavity that mold 6 is made of taper side face, loam cake 3, bottom, hollow section, mold 6 bottoms are higher than taper side face following peripheral, make between taper side face and the bottom and form cavity.Mold 6 upper ends are provided with handle 1, and the two ends prolong knot of handle 1 is on the two sides of mold 6, and the shell upper wall is inserted at handle 1 two ends, and handle 1 two ends are provided with pin-and-hole, avoid handle 1 to throw off in the pin-and-hole at locking pin 4 insertion handles 1 two ends.A screw thread depression bar 2 is arranged, screw thread is arranged at the vertical rod bottom of screw thread depression bar 2, circular platen is fixed on the top of the vertical rod of screw thread depression bar 2, the upper end fixed transverse rod of the vertical rod of screw thread depression bar 2, the vertical rod of screw thread depression bar 2 is passed central through hole and its lower end of mold 6 and is stretched out in mold 6 outsides, and the circular platen of the vertical rod of screw thread depression bar 2 is pressed on mold 6 upper surfaces.
