Abstract
The utility model discloses a concrete preformed hole die. The concrete preformed hole die is characterized in that a die body is a hollow circular truncated cone body (1), a plurality of tack holes (4) which are communicated to the bottom end from the top end are evenly formed in the hollow circular truncated cone body (1) along the peripheral wall of the hollow circular truncated cone body (1), outer turning rings (2) are arranged at the top end of the hollow circular truncated cone body (1), and inner reinforced rings (3) are arranged at the bottom end of the hollow circular truncated cone body (1). The concrete preformed hole die is simple in structure, convenient to use, low in cost due to the fact that the die is made of plastics, capable of being recycled and saving materials, and capable of reducing working procedures, saving time and saving labor in the constructing process of the die.
Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of concrete preformed hole mould.
Background technology
The formation of traditional concrete preformed hole is that pvc pipe is sawn into segment, bores the nail hole at the segment pvc pipe, with nail it is followed closely on template then.In the segment pvc pipe, fill sand, prevent that concrete from flowing into wherein.The segment pvc pipe is connected with concrete when building, treat concrete setting after, stripping, abate segment pvc pipe, and hole flushing, pipe laying after the hole flushing.Because preformed hole is not of uniform size to be caused, and also need hang the mould plug-hole again behind the pipe laying.This method not only operation various, take time and effort, and pvc pipe waste is also very serious.
Also have water to bore hole knockout in addition, but seldom use now, not only take time and effort, and influence structure.The building site forbids that generally water bores punching.
Summary of the invention
The purpose of this utility model provides a kind of material that can reduce and expends and make the more convenient labour-saving of installation work concrete preformed hole mould.Advantage such as that this concrete preformed hole mould has is simple in structure, with low cost, can reuse.
For achieving the above object, the utility model by the following technical solutions:
A kind of concrete preformed hole mould, its design feature are that described die main body is a hollow round table body, and described hollow round table body evenly is provided with a plurality of nail holes that connect from the top to the bottom along its perisporium.
The utility model design feature also is:
The top of described hollow round table body is provided with the circle that turns up.
In order to prevent die deformation, the utility model can also be taked further technical scheme:
Inner stiffener ring is established in bottom at described hollow round table body.
Described hollow round table body bottom surface diameter is consistent with want buried pipeline diameter.
The long 2-4cm of concrete thickness that described hollow round table body aspect ratio will be built.
During construction, concrete preformed hole mould is followed closely on template by the nail hole with nail, again concreting on template.After treating concrete setting, take out nail, the circle that turns up of gently prizing the top with goat's horn end or the crowbar of claw hammer more just desirablely goes out mould.So just reserved the preformed hole that meets pipeline specifications.If there is concrete to pour into mould, as long as with hammer it is pounded out to big opening end from the osculum end.Behind the later stage pipe laying, because the bottom specification of preformed hole is consistent with pipeline specifications, so do not need to hang again just direct plug-hole of mould.
Compared with the prior art, the utility model beneficial effect is embodied in:
1. the utility model is simple in structure, easy to use.
2. the utility model can reuse, and saves material.
3. the utility model can reduce installation procedure, saves set-up time and cost.
4. the employed material of the utility model is plastics, and cost is low.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is done further detailed explanation:
Embodiment 1: as shown in the figure, according to the specification of want pipe laying and the concrete thickness that will build, hollow round table body 1 made of plastic, the upper end of hollow round table body 1 has three through to the nail hole 4 of lower end, there is the circle 2 that turns up the upper end, so that take out mould during form removal, hollow round table body bottom surface diameter is consistent with want buried pipeline diameter; The long 2-4cm of the concrete thickness that the Rotary-table aspect ratio will be built.During construction, hollow round table body 1 is followed closely on template 7 by nail hole 4 with nail 5, again concreting 6 on template 7.After treating that concrete 6 solidifies, take out nail 5, gently prize turning up of top with the goat's horn end of claw hammer or crowbar again and enclose 2, just desirablely go out mould.So just reserved the preformed hole that meets pipeline specifications.If there is concrete to pour into mould, as long as with hammer it is pounded out to big opening end from the osculum end.Behind the later stage pipe laying, because the bottom specification of preformed hole is consistent with want buried pipeline 8 specifications, so do not need to hang again just direct plug-hole of mould.And mould can reuse.
Embodiment 2: according to the specification of want pipe laying and the concrete thickness that will build, hollow round table body 1 made of plastic, the upper end of hollow round table body 1 has three or more through to the nail hole 4 of lower end, the upper end has turns up circle 2 so that take out mould during form removal, there is inner stiffener ring 3 lower end, to prevent die deformation.Other are with embodiment 1.
