Description
Technical field
The utility model relates to technical field of building construction, especially a kind of mould making concrete floorslab preformed hole.
Background technology
In building operations, the indwelling of floor preformed hole is an indispensable working procedure, especially in the work progress of concrete floorslab, in order to meet water, electricity, vapour later stage install needs, floor preformed hole must be reserved by designing requirement during construction.Prior art makes the direct pre-buried method that floor preformed hole often adopts a pre-buried tub or can, the outside iron nail of box body or iron wire and floor nearby reinforcing bar carry out colligation and fix; Problems existing is, tub or can fixing unreliable, because the lateral pressure by flowing concrete affects in concrete placement, easily cause box body to produce drift, cause the center line generation deviation of preformed hole, the positional precision of preformed hole can not ensure, in addition, lateral pressure by flowing concrete affects, the tub reserved or can mould easily cause crooked, directly affect later stage water, electricity, the stringing of vapour construction and installation.
Utility model content
The purpose of this utility model is a kind of mould making concrete floorslab preformed hole provided for the deficiencies in the prior art, the utility model overcomes mould, in casting process, drift or crooked defect easily occurs, and has structure simple, easy for installation and repeatedly can have enough to meet the need the advantage of use.
The concrete technical scheme realizing the utility model object is:
A kind of mould making concrete floorslab preformed hole, its feature comprises cylindrical shell, connector and upper cover, described cylindrical shell establishes the back taper stage body of base plate in being, the center of its base plate is provided with guide pillar hole, connector is made up of lead, screw rod, Non-return ring and nut, one end of lead is provided with external screw thread, the other end is provided with dead bolt, nut engages with one end of screw rod, lead welds with the other end of screw rod, Non-return ring engages with the external screw thread of lead, be provided with screw hole centered by upper cover, circular cover that periphery is provided with flange, cover plate is provided with handle and peep hole;
Described upper cover is through the top of flange spiral-lock at cylindrical shell, and the screw rod of connector is through in the screw hole of upper cover, lead is through in the guide pillar hole of cylindrical shell; Described Non-return ring is provided with marking line.
The utility model overcomes floor prepared hole die, in casting process, drift or crooked defect easily occurs, and has structure simple, easy for installation and repeatedly can have enough to meet the need the advantage of use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the upward view of Fig. 1;
Fig. 4 is using state schematic diagram of the present utility model.
Detailed description of the invention
Consult Fig. 1, Fig. 2, Fig. 3, the utility model it comprise cylindrical shell 1, connector 2 and upper cover 3, described cylindrical shell 1 establishes the back taper stage body of base plate 11 in being, the center of its base plate 11 is provided with guide pillar hole 12, connector 2 is by lead 21, screw rod 22, Non-return ring 23 and nut 25 are formed, one end of lead 21 is provided with external screw thread, the other end is provided with dead bolt 24, nut 25 engages with one end of screw rod 22, lead 21 welds with the other end of screw rod 22, Non-return ring 23 engages with the external screw thread of lead 21, screw hole 34 is provided with centered by upper cover 3, periphery is provided with the circular cover of flange 31, cover plate is provided with handle 32 and peep hole 33,
Described upper cover 3 is through flange 31 spiral-lock at the top of cylindrical shell 1, and the screw rod 22 of connector 2 is through in the screw hole 34 of upper cover 3, lead 21 is through in the guide pillar hole 12 of cylindrical shell 1;
Described Non-return ring 23 is provided with marking line.
The utility model uses like this:
Below for the work progress of concrete floorslab, further illustrate as follows to concrete enforcement of the present utility model:
After the template 4 of floor has installed, survey crew should by design drawing by the size of preformed hole and accurate location cross hairs and circle distance pole in template 4;
At the circular hole that one, template 4 cross hairs location place brill is identical with lead 21 diameter, at two Symmetry Edges flutings of circular hole, the dead bolt 24 accomplishing lead 21 by keyhole;
After treating the reinforcing bar binding above template 4, by brushing interleaving agent on cylindrical shell 1 external surface made, the cylindrical shell 1 of corresponding specification is with it selected by preformed hole diameter, by upper cover 3 through flange 31 spiral-lock at the top of cylindrical shell 1, the screw rod 22 of connector 2 is through in the screw hole 34 of upper cover 3, lead 21 is through in the guide pillar hole 12 of cylindrical shell 1, marking line on inspection Non-return ring 23 is square consistent, stand-by with lead 21 dead bolt 24;
The base plate 11 of cylindrical shell 1 is placed in above the keyhole of template 4, by the guide pillar hole 12 of connector 2 together with the keyhole of dead bolt 24 through floor, connector 2 is rotated 90 °, the marking line observed on Non-return ring 23 by peep hole 33 is vertical with keyhole, nut 25 on locking connector 2 screw rod 22, is fixed in template 4 by dead bolt 24 and the cylindrical shell 1 of lead 21 by the utility model;
Complete the pouring concrete of cast-in-situ floor, after concrete is solidifying in advance, i.e. dismountable the utility model, demolishing process is as follows, loosens the nut 25 on connector 2 screw rod 22, connector 2 is rotated 90 °, the marking line observed on Non-return ring 23 by peep hole 33 is parallel with keyhole, catches the handle 32 on upper cover 3, rocks gently, and the utility model is extracted in concrete and template 4, use in order to turnover next time.
The mode that the utility model adopts connector 2 to be connected with template 4, because fixing means is reliable, makes the position of template 4 preformed hole can control within the scope of designing requirement completely, and the stringing of constructing for later stage water, electricity, vapour and installation provide guarantee.
The profile of the utility model cylindrical shell 1 adopts the design of rounding frustum, make the concrete floor preformed hole after pouring into a mould also in large, lower young reverse taper suitable for reading, when after the stringing and installation of water, electricity, vapour, be beneficial to the shutoff of hole, floor antileaking after shutoff, good water-proof effect.
The utility model can be produced by the specification standardization of preformed hole, repeatedly can have enough to meet the need use, saves material.
The utility model is not only applicable to the floor preformed hole in production technique face, but also can be suitable for the making of the wallboard preformed hole of vertical plane.
