Abstract
The utility model discloses a kind of concrete preformed hole shaping device, it is characterized in that: described shaping device comprises flexible gas-filled body (1), the top of flexible gas-filled body (1) is provided with valve nozzle (2), and described flexible gas-filled body (1) longitudinal profile in the deflated condition is mutually stacked by multiple identical isosceles trapezoid and forms.This is a kind of easy for installation, saves PVC, simplifies construction sequence, saves construction cost, and can the concrete preformed hole shaping device of recycled for multiple times.
Description
Technical field
The utility model relates to a kind of shaping device, particularly a kind of concrete preformed hole shaping device.
Background technology
In the process of concrete engineering construction, according to need of work, a large amount of embedded holes and built-in fitting may be there is in concrete structure, existing construction technology is all be embedded in by pvc pipe in concrete to form embedded hole, the shortcoming of this traditional construction technology is that to bury process underground easily damaged at pvc pipe, cause embedded hole to lose efficacy, or pvc pipe fill up by adhesive tape spillage.Even if pvc pipe is buried underground successfully, also want lost labor and air compressor machine to go to dispose pvc pipe to obtain embedded hole, and then dabbing process is carried out to embedded hole, waste time and energy, improve the cost of production of unit in charge of construction.
Summary of the invention
The utility model is the above-mentioned deficiency in order to solve existing for prior art, proposes a kind of easy for installation, saves PVC, simplify construction sequence, save construction cost, and can the concrete preformed hole shaping device of recycled for multiple times.
Technical solution of the present utility model is: a kind of concrete preformed hole shaping device, it is characterized in that: described shaping device comprises flexible gas-filled body 1, the top of flexible gas-filled body 1 is provided with valve nozzle 2, and described flexible gas-filled body 1 longitudinal profile in the deflated condition is mutually stacked by multiple identical isosceles trapezoid and forms.
Compared with the existing technology, tool has the following advantages the utility model:
The concrete preformed hole shaping device of this kind of form of structure, its structure is simple, designs ingenious.It exists for traditional concrete preformed hole processing mode: to bury in pvc pipe process pvc pipe cracky underground or filled up by slurry; Pvc pipe is needed to remove and dabbing process, cause operation various, consume the problems such as a large amount of manpower and materials, design a kind of structure can inflated, be vented, utilize it directly can generate satisfactory preformed hole in the process of concreting, condensation, eliminate the operation of removing pvc pipe and dabbing process, reach the object simplifying construction sequence, save construction cost, and it can also be reused, effectively can control the cost of preformed hole processing.Therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.As shown in Figure 1: a kind of concrete preformed hole shaping device, it comprises a flexible gas-filled body 1, this flexible gas-filled body 1 can adopt rubber to make, the top of flexible gas-filled body 1 is provided with valve nozzle 2, when flexible gas-filled body 1 is in inflated condition, the section of its longitudinal direction is mutually stacked by multiple identical isosceles trapezoid and forms.
The course of work of the concrete preformed hole shaping device of the utility model embodiment is as follows: first valve nozzle 2 and air pump are coupled together by pipeline, air pump is utilized to inflate for flexible gas-filled body 1, inflate rear closedown valve nozzle 2, and multiple shaping device is placed, be fixed on the position needing to arrange embedded hole, then concrete pouring is carried out, after concrete setting, after its intensity reaches about 15Mpa, open valve nozzle 2, and utilize getter device to be extracted out by the gas in flexible gas-filled body 1, flexible gas-filled body 1 can take out from the concrete of curdled appearance, then can stay in concrete and flexible gas-filled body 1 preformed hole that matches of shape in the deflated condition,
Due to the shape (mutually stacked by multiple identical isosceles trapezoid and form) that flexible gas-filled body 1 longitudinal profile is in the deflated condition special, therefore the preformed hole formed by this kind of shaping device does not need again to carry out dabbing process, directly can use, use manpower and material resources sparingly.
