The utility model discloses a preformed hole model for building plumbing pipe, including outer mould pipe and centre form pipe, the spacing of lower extreme fixedly connected with of outer mould inside pipe wall, the equal fixedly connected with connecting plate in both sides on outer mould pipe top, two the connecting plate external member, two have been cup jointed on the connecting plate surface equal fixedly connected with inside pipe between the connecting plate external member, the interior roof swing joint of inside pipe has the closing cap, two the lower extreme of connecting plate external member is all seted up flutedly. This a preformed hole model for building plumbing pipe, through the setting of interior mould pipe, when personnel pour all formwork prop up, it is rotatory with the centre form pipe after inserting outer mould pipe with the centre form pipe, make the connecting plate external member block the connecting plate to can be intraductal with the centre form pipe is fixed to outer mould, in order to prevent that the concrete is at the in-process that solidifies with outer mould socle to deformation, lead to the drawing of patterns back preformed hole inner wall uneven, give the unable insertion of drain pipe, thereby personnel need the secondary to be maintained.
Description
Technical Field
The utility model relates to a building construction articles for use technical field specifically is a preformed hole model for building plumbing pipe.
Background
The floor board prepared hole and the installation water supply and drainage pipe in the existing building construction are relatively complicated, when the floor board is cast in place, an embedded part is firstly manufactured, the embedded part is generally nailed into a model with the aperture equivalent to that of the water pipe by a template, and is nailed on the floor board template, and is separated from the template after pouring, and a hole is formed on the dried cement concrete floor board; when the concrete pouring device is installed, a water supply and drainage pipe penetrates through a reserved hole of a floor slab, a template is arranged at the bottom of the reserved hole of the floor slab, then cement concrete is poured, the water supply and drainage pipe and the floor slab are connected into a whole, the existing reserved hole is more original and labor-consuming, when a model is processed, operations such as sawing, nailing and the like are needed, the operation is more difficult to master during installation, the template needs to be fixed below the poured floor slab and is spliced by two half modules with semicircular holes, then the cement concrete is poured around the upper surface of the floor slab, and the cement concrete pouring device usually needs to be reversely worked, and the hole of the template can be used after being reworked.

(III) advantageous effects
The utility model provides a preformed hole model for building plumbing pipe possesses following beneficial effect:
1. this a preformed hole model for building plumbing pipe, through the setting of interior mould pipe, when personnel pour all formwork prop up, it is rotatory with the centre form pipe after inserting outer mould pipe with the centre form pipe, make the connecting plate external member block the connecting plate to can be intraductal with the centre form pipe is fixed to outer mould, in order to prevent that the concrete is at the in-process that solidifies with outer mould socle to deformation, lead to the drawing of patterns back preformed hole inner wall uneven, give the unable insertion of drain pipe, thereby personnel need the secondary to be maintained.
2. This a preformed hole model for building plumbing pipe, through the setting of closing cap, the back is installed with outer mould pipe and centre form pipe to personnel, installs the top to interior mould pipe with the closing cap to prevent that rubbish that drops in the construction etc. from centre form pipe dropping to lower floor, cause the unnecessary injury to the constructor of lower floor.
Drawings
FIG. 1 is a schematic perspective view of the present invention;
fig. 2 is a schematic view of the front perspective structure of the present invention.
In the figure: 1. an outer mold tube; 2. an inner mold tube; 3. a limiting strip; 4. a connecting plate; 5. a connection plate kit; 6. sealing the cover; 7. and (4) a groove.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1 to 2, the present invention provides a technical solution: a preformed hole model for building water supply and drainage pipes comprises an outer mold pipe 1 and an inner mold pipe 2, wherein the lower end of the inner wall of the outer mold pipe 1 is fixedly connected with a limiting strip 3, two sides of the top end of the outer mold pipe 1 are fixedly connected with connecting plates 4, and the surfaces of the two connecting plates 4 are sleeved with connecting plate external members 5;
through the arrangement of the inner mold pipe 2, when a worker pours all the templates, the inner mold pipe 2 is inserted into the outer mold pipe 1 and then the inner mold pipe 2 is rotated, so that the connecting plate kit 5 clamps the connecting plate 4, the inner mold pipe 2 can be fixed into the outer mold pipe 1, and the outer mold pipe 1 is prevented from being pushed to deform in the solidification process of concrete, so that the inner walls of reserved holes after demolding are not uniform, a water supply and drainage pipe cannot be inserted, and the worker needs secondary finishing;
an inner mold pipe 2 is fixedly connected between the two connecting plate external members 5, the inner top wall of the inner mold pipe 2 is movably connected with a sealing cover 6, through the arrangement of the sealing cover 6, after the personnel install the outer mold pipe 1 and the inner mold pipe 2, the sealing cover 6 is installed at the top end of the inner mold pipe 2, thereby preventing garbage and the like falling in construction from falling to the lower layer from the inner mold pipe, unnecessary damage to the constructors on the lower layer is caused, the lower ends of the two connecting plate kits 5 are respectively provided with a groove 7, through the arrangement of the grooves 7, when the model is dismantled, a worker can insert a tool into the grooves 7 at the two ends to tilt up, so that the model can be taken out of the reserved hole, the connecting plate 4 is matched with the connecting plate suite, the outer mold pipe 1 and the inner mold pipe 2 are both cylinders, the outer mold pipe 1 is made of rubber, the inner mold pipe 2 is made of stainless steel, the surface of the sealing cover 6 is provided with a warning strip, through the setting of warning strip, can prevent that personnel from kicking the model carelessly and being moved to and cause unnecessary injury when being under construction.
