Abstract
The utility model provides a ware is reserved to pipeline preformed hole, includes the centre form of tubbiness and the external mold of tube -shape, the outer wall of centre form and the contact of the inner wall of external mold, and the contact surface is the conical surface. The centre form includes staving and gim peg, install the end cover on the staving top end opening, open at the end cover center has the intercommunicating pore, staving bottom center is provided with the screw hole, gim peg bottom is provided with the self tapping screw head, and the top level is provided with the anchorage bar, the gim peg bottom is passed the intercommunicating pore and is passed through threaded connection with the screw hole. Ware is reserved to pipeline preformed hole makes the centre form strut the external mold through the contact surface of the conical surface, and after the completion of moulding plastics, the centre form contracts in taking out and making the external mold, and directly will reserve the ware and take out from the preformed hole, simple structure, the processing ease improves the operating efficiency, and repeatedly usable can not increase extra cost yet.
Description
Technical field
The utility model relates to the realm of building construction, specifically, is that a kind of pipeline preformed hole reserves device.
Background technology
In building construction, floor has been reserved some preformed holes, for fixing a drainpipe, and these preformed holes are generally reserved by mould when injection moulding floor, after floor injection moulding completes, mould is needed to take out from preformed hole, because concrete solidifies, preformed hole very consolidation mould is encased, mould is difficult to remove, even need die failure, effort of taking a lot of work, too increases construction cost.
Propose a kind of reserved device in first patent " device is reserved in quickly dismantled concrete floor hole " (publication number: CN202299415U), although solve the problems referred to above, still there is more deficiency.Reserved device before use must smearing release agent, and must ensure to smear completely, otherwise after floor injection moulding completes, reserved device is still difficult to take out, and add the use cost of release agent, too increase working procedure, inefficiency, cost is high.
Utility model content
The utility model, for current reserved device troublesome poeration, inefficiency, high in cost of production problem, proposes a kind of new pipeline preformed hole and reserves device.
Pipeline preformed hole of the present utility model reserves device, comprises the internal mold of tubbiness and the external mold of tubular, the outer wall of internal mold and the contact internal walls of external mold, and contact surface is the conical surface.
Described internal mold comprises staving and dead bolt, described staving top end opening is provided with end cap, end cap central has intercommunicating pore, described staving bottom centre is provided with screwed hole, self-tapping screw head is provided with bottom described dead bolt, top level is provided with anchorage bar, passes intercommunicating pore and be threaded connection with screwed hole bottom described dead bolt.
Preferably, described end cap is arranged in the step trough of staving opening setting, and the thickness of described end cap is less than the degree of depth of step trough, and described end cap sidewalls contacts with the inside wall of step trough, and contact surface is the conical surface.
The beneficial effects of the utility model are: pipeline preformed hole reserves device makes internal mold be strutted by external mold by the contact surface of the conical surface, after injection moulding completes, internal mold takes out and external mold can be made to inside contract, direct reserved device to be taken out from preformed hole, structure is simple, processing ease, improves operating efficiency, reusable, also can not increase extra cost.
End cap is positioned at step trough, contact surface is also the conical surface, end cap is moved down also internal mold top to be strutted, the top of external mold struts by internal mold top again that strut, the top of external mold and bottom can both be strutted uniformly, prevent because of external mold that to strut degree uneven, cause aperture, preformed hole top to be greater than aperture, bottom and make external mold be difficult to take out, also make preformed hole size even, be convenient to the loading of drainage pipe during subsequent construction and the filling injection moulding in preformed hole gap.
Accompanying drawing explanation
Accompanying drawing 1 reserves the structural representation of device for this pipeline preformed hole.
Detailed description of the invention
In order to understand structure of the present utility model, feature and other object further, the appended preferred embodiment of existing combination is described in detail as follows, and illustrated preferred embodiment is only for illustration of the technical solution of the utility model, and non-limiting the utility model.
Detailed description of the invention of the present utility model is as follows:
Embodiment one:
As shown in Figure 1, this pipeline preformed hole is reserved device and is comprised the internal mold 1 of tubbiness and the external mold 2 of tubular.
The outer wall of internal mold 1 and the contact internal walls of external mold 2, contact surface is the conical surface.
Internal mold 1 comprises staving 3 and dead bolt 4, staving 3 top end opening is provided with end cap 5, end cap 5 center has intercommunicating pore 6, staving 3 bottom centre is provided with screwed hole 7, self-tapping screw head 8 is provided with bottom dead bolt 4, top level is provided with anchorage bar 9, passes intercommunicating pore 6 and be threaded connection with screwed hole 7 bottom dead bolt 4.
During use, be placed in the steel bar framework of floor by whole reserved device, bottom is positioned on wooden form.Rotate dead bolt 4, the self-tapping screw head 8 of dead bolt 4 lower end is shot in wooden form, and whole dead bolt 4 moves down, the anchorage bar 9 at dead bolt 4 top pulls down moved end lid 5, make end cap 5 drive staving 3 to move down, whole internal mold 1 is moved down, by the conical surface, external mold 2 is outwards strutted.
After concreting completes, treat that concrete setting is complete, rotate dead bolt 4, self-tapping screw head 8 is drawn off from wooden form, dead bolt 4 moves, whole internal mold 1 loses lower pulling force, take out from external mold 2, and external mold 2 is not retracted it outwards being pushed due to internal mold 1, external mold 2 outer wall directly departs from the preformed hole inwall be injection molded into, taken out from preformed hole by external mold 2, the construction of preformed hole completes.
Embodiment two:
Embodiment two forms substantially identical with the structure of embodiment one, and difference is:
End cap 5 is arranged in the step trough 10 of staving 3 opening setting, and the thickness of end cap 5 is less than the degree of depth of step trough 10, and end cap 5 sidewall contacts with the inside wall of step trough 10, and contact surface is the conical surface.
When reserved device is fixed on wooden form, end cap 5 also receives the downward pulling force of anchorage bar 9 and inside wall along step trough 10 moves down, push the sidewall at internal mold 1 staving 1 top, staving 1 top outwards struts, the top of pushing external mold 2 further outwards struts, external mold about 2 is all evenly strutted, the preformed hole uniform pore diameter made everywhere, be convenient to the dismounting of external mold 2 and the installation of follow-up drainage pipe and fill injection moulding.
