Abstract
The utility model discloses a prepared hole die of concrete, which comprises an elastic die, wherein the area of the top surface of the elastic die is smaller than the area of the bottom surface, a cavity is arranged inside the elastic die, the top of the elastic die is provided with a through hole, the through hole is communicated with the cavity, and a sealing cap is arranged on the through hole. The shape of the elastic die is in a positive four-rowed platform shape, and the through hole is connected with the sealing cap through threads. The top of the elastic die is provided with a pulling ring. The die has the advantages that the structure is reasonably designed, the die can form a preformed hole whose upper portion is small and lower portion is big during concrete casting, is convenient to fix and use, can be conveniently taken out after the solidification of the concrete, and can be repeatedly used.
Description
Technical field
The utility model relates to a kind of casting mold, specifically a kind of concrete preformed hole mould.
Background technology
In the building course in many factory buildings workshop, need when cast ground, reserve the preformed hole that solid mechanical equipment is used, traditional method is to use timber as the preformed hole mould, but timber is difficult for taking out from preformed hole after concrete setting, can't reuse.For addressing this problem, someone has designed some inflating dies, substitute timber as the preformed hole mould, inflating die can be removed after concrete setting easily, but because himself intensity is lower, when cast,, cause the shape of preformed hole not reach instructions for use easily by concrete crimp; The somebody designs folding preformed hole mould, can form up-small and down-big preformed hole in concrete, but this mould junction sealed by concrete easily, can't fold, and causes it to be removed from preformed hole, therefore is not used widely.
Summary of the invention
The purpose of this utility model provides a kind of concrete preformed hole mould, and it can form up-small and down-big preformed hole when concrete pouring, is convenient to the fixed expansion bolt, and can takes out easily after concrete setting, reuses.
The utility model is achieved through the following technical solutions for achieving the above object: comprise elastic mould, the top surface area of elastic mould is less than base area, be provided with cavity in the elastic mould, the elastic mould top is provided with through hole, and through hole communicates with cavity, and sealing cap is installed on the through hole.Elastic mould be shaped as positive truncated rectangular pyramids shape, between through hole and the sealing cap by being threaded.Draw ring is installed at the elastic mould top.
Advantage of the present utility model is: reasonable in design, it can form up-small and down-big preformed hole when concrete pouring, be convenient to fixing the use, and can take out easily after concrete setting, reuses.
Description of drawings
Fig. 1 is the utility model structural representation; Fig. 2 is the plan structure schematic diagram of Fig. 1.
The specific embodiment
Concrete preformed hole mould described in the utility model comprises elastic mould 1, the top surface area of elastic mould 1 is less than base area, be provided with cavity 2 in the elastic mould 1, elastic mould 1 top is provided with through hole 3, through hole 3 communicates with cavity 2, sealing cap 4 is installed on the through hole 3, and said structure can be realized goal of the invention of the present utility model.During use, with sealing cap 4 sealing, when carrying out concrete pouring elastic mould 1 is inserted in the concrete, the air in the cavity 2 have certain pressure, make the elastic mould 1 can be by concrete crimp; After concrete setting, take off sealing cap 4, because elastic mould 1 itself has certain elasticity, the air in the cavity 2 is discharged from simultaneously, the sidewall of elastic mould 1 can compress to the center, so elastic mould 1 can be extracted out in preformed hole easily.Pressure when sealing in the cavity 2 in order to strengthen can also inject liquid in use in cavity, with sealing cap 4 sealings, prevent that further elastic mould 1 is by concrete crimp again.
Concrete preformed hole mould described in the utility model can also adopt other multiple shape, and wherein preferred scheme is the positive truncated rectangular pyramids shape of being shaped as of elastic mould 1, adopts this shape solid mechanical equipment better.
For the convenience of the users elastic mould 1 is taken out in preformed hole, draw ring 5 can be installed at elastic mould 1 top.
