Detailed description of the invention
In order to more clearly understand technology contents of the present utility model, describe in detail especially exemplified by following examples.
Refer to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, in a specific embodiment of the present utility model, concrete wall pocket moulding form of the present utility model comprises: cylindrical shell 1, and described cylindrical shell 1 is circumferentially divided at least two panels cylinder sheet 11; Pull bar 2, described pull bar 2 is plugged in described cylindrical shell 1 along the axis of described cylindrical shell 1, and described pull bar 2 has first end 21 and the second end 22; And support bar 3, described support bar 3 and described cylinder sheet 11 one_to_one corresponding, described support bar 3 is between described pull bar 2 and described cylinder sheet 11, and the two ends of described support bar 3 are rotatably connected with described pull bar 2 and described cylinder sheet 11 direction along the axis perpendicular to described cylindrical shell 1 respectively; Wherein, at least cylinder sheet 11 described in a slice is free to rotate towards described the second end 22.
Support bar 3 supports the integral rigidity keeping cylindrical shell 1 when being mainly used in forming cylindrical shell 1, plays pull-up cylinder sheet 11 when cylindrical shell 1 is packed up.Because the two ends of described support bar 3 are rotatably connected with described pull bar 2 and described cylinder sheet 11 direction along the axis perpendicular to described cylindrical shell 1 respectively, when pull bar 2 is erect, cylinder sheet 11 can with pull bar 2 for the center of circle, with support bar 3 for radius, rotate up and down, thus near or away from pull bar 2.When above-mentioned cylindrical shell 1 is packed up by needs, by pull bar 2 pull-up, the cylinder sheet 11 free to rotate towards described the second end 22 can near pull bar 2, then all the other sheets 11 can thereupon near pull bar 2, realize shrinking, when needs strut a sheet 11 form cylindrical shell 1 time, pull bar 2 is pressed down, cylinder sheet 11 is strutted into cylindrical shell 1.
The number of described cylinder sheet 11 can be determined as required, and preferably, the number of described cylinder sheet 11 is between 2 ~ 6, such as, can be 2,3,4,5 or 6, can certainly more multi-disc, but can cause complex structure, inconvenient operation.Refer to shown in Fig. 1 ~ Fig. 2, in a specific embodiment of the present utility model, the number of described cylinder sheet 11 is 4.
The shape of described cylinder sheet 11 can be identical, also can not be identical, when cylinder sheet 11 is 2, if the shape of cylinder sheet 11 is identical, then cylinder sheet 11 can mutually against, do not have a sheet 11 free to rotate towards described the second end 22, cannot realize packing up, therefore, preferably, when the number of described cylinder sheet 11 is more than 3, the shape of described cylinder sheet 11 is identical, can certainly be different.Refer to shown in Fig. 1 ~ Fig. 4, in a specific embodiment of the present utility model, when the number of described cylinder sheet 11 is 4, the shape of described cylinder sheet 11 is identical.
The two ends of described support bar 3 are rotatably connected with described pull bar 2 and described cylinder sheet 11 respectively and can adopt any suitable structure.Refer to shown in Fig. 1 ~ Fig. 4, in a specific embodiment of the present utility model, the two ends of described support bar 3 are rotatably connected by rotating shaft 4 with described pull bar 2 and described cylinder sheet 11 respectively.
Described support bar 3 can be removably connect with described cylinder sheet 11, also can being non-dismountable connection, in order to realize independent assortment from different cylinder sheet 11, referring to shown in Fig. 1 ~ Fig. 2, in a specific embodiment of the present utility model, described support bar 3 removably connects with described cylinder sheet 11.Such as when described support bar 3 is rotatably connected by rotating shaft 4 with described cylinder sheet 11, rotating shaft 4 two ends are spacing by nut (not shown), nut can be unloaded, rotating shaft 4 extracted out when needing, thus are separated support bar 3 and cylinder sheet 11.
Described support bar 3 can be removably connect with described pull bar 2, also can be non-dismountable connection, and in order to pull bar 2 realizes independent assortment from different support bar 3, preferably, described support bar 3 removably connects with described pull bar 2.Such as when described support bar 3 is rotatably connected by rotating shaft 4 with described pull bar 2, rotating shaft 4 two ends are spacing by nut (not shown), nut can be unloaded, rotating shaft 4 extracted out when needing, thus are separated support bar 3 and pull bar 2.
In order to prevent cement paste from flowing into cylindrical shell 1, preferably, between described cylinder sheet 1, be provided with seal 12.Seal 12 can be any suitable seal, such as diaphragm seal, weather strip.Refer to shown in Fig. 1 ~ Fig. 2, in a specific embodiment of the present utility model, described seal 12 is sheet rubbers.
For the ease of construction, preferably, described the second end 22 is provided with fixed structure 23.Described fixed structure 23 can be any suitable structure, and more preferably, described fixed structure 23 is tip, pawl end or three forks.Refer to shown in Fig. 3 ~ Fig. 4, in a specific embodiment of the present utility model, described fixed structure 23 is most advanced and sophisticated, namely sharp-pointed gland.
Described pull bar 2 can be arranged in any suitable position of described cylindrical shell 1, and preferably, described pull bar 2 is positioned at the center of described cylindrical shell 1.Certainly, described pull bar 2 also can not be positioned at the center of described cylindrical shell 1, and now the length of support bar 3 can be different.
During use, the utility model is placed on construction base plate such as wooden form, the second end 22, near wooden form, presses down the first end 21 of pull bar 2, and strutting a sheet 11 through support bar 2 becomes cylindrical shell 1, and by the fixed structure 23 of the second end 22, cylindrical shell 1 is fixed on wooden form, then, in the outer cast-in-situ concrete of cylindrical shell 1, when removing mould after concrete setting, the first end 21 of pull bar 2 is pulled upwardly, cylinder sheet 11 rotates for radius with support bar 3, realizes packing up.
Therefore, adopt the utility model, knock the shortcoming that vibrating mould destroys reserving hole when avoiding traditional hole reservation mould form removal, concrete wall pocket moulding form location of the present utility model is fixed, assembling and disassembling convenient, is more conducive to finished product protection of constructing.Cylinder sheet 11, support bar 3 and pull bar 2 can independent assortments, realize different-diameter hole to be provided and use, reduce usage measure expense to greatest extent.
Although the utility model is mainly for concrete wall pocket, be not limited thereto, also can be used for the situation that other needs hole to be provided.
In sum, concrete wall pocket moulding form of the present utility model can realize the complete of concrete wall pocket mouth, occupies space less, thus convenient in carrying and reduction warehouse cost, the box out requirement of different holes can be realized flexibly, play the effect of cost efficiency, be suitable for large-scale promotion application.
One skilled in the art will understand that the embodiment of the present utility model shown in foregoing description and accompanying drawing only limits the utility model as an example and not.
As can be seen here, the purpose of this utility model is complete and be effectively achieved.Function of the present utility model and structural principle are shown in an embodiment and are illustrated, do not deviating under described principle, embodiment can do any amendment.So the utility model includes all variant embodiment based on claim spirit and right.
