Description

A kind of to drawing device
Technical field
This utility model belongs to building implement technical field, more particularly, to a kind of to drawing device.
Background technology
At present, in the cast-in-place concrete construction of building, Screw arbor with nut at both-ends device can typically all be adopted.Traditional to drawing spiral shell Bar is integral type structure, and after concrete cast-in-situ finishes, not only screw rod cannot take out, and stretches out the screw rod impact mould of wall outer side The dismounting of plate, needs to slice off the part of exposing surface, wastes great deal of steel, and can not reuse, wastes manpower wealth Power.
For solving above-mentioned technical problem, in prior art, disclose dismountable Screw arbor with nut at both-ends, such as patent CN104481145A discloses a kind of template and admittedly uses sleeve bolt to tension, includes a length and is equal to thickness of wall body and bilayer The sleeve of wall form thickness sum, one end of sleeve is provided with a closed head, and this closed head and sleeve adopt engineering plastics Injection moulding integrated molding, is provided with sealing ring between closed head and wall form, the other end of described sleeve is provided with female thread, institute State female thread to coordinate with fastening bolt, be provided with rubber seal ring between described fastening bolt and wall form, this rubber seal The endoporus of ring is coordinated with the outer wall extruding of fastening bolt.Above-mentioned Screw arbor with nut at both-ends can be dismantled and repeatable utilization, has saved people Power financial resources.But, the error being made due to prefabricated components, can make the width in cast-in-place region and design ratio that error occurs, be difficult to protect Card length sleeve is equal to thickness of wall body and two-layer wall template thickness sum, and above-mentioned excessively multiple to the structure drawing sleeve bolt Miscellaneous, in addition, entirely treating that casting area all leads to the waste of material using sleeve.
In sum, need badly and develop that a kind of structure is simple, cost savings, easy to use to drawing device.
Utility model content
The purpose of this utility model be provide that a kind of structure is simple, cost savings, easy to use to drawing device.
Above-mentioned purpose is to be achieved through the following technical solutions：A kind of to drawing device, including sleeve, sleeve pipe and screw rod, described Screw rod is worn and is connect described sleeve pipe, and one end of described screw rod and sleeve are threaded connection, and described screw rod is provided with nut.In this practicality New install and use during, sleeve is embedded in prefabricated components, and the opening of sleeve connects, in formwork towards outside prefabricated components When, screw rod is socketed with the screw rod precession embedded sleeve barrel of sleeve pipe, after model sheetinstallat, uses nut fixed form.The length of described sleeve pipe Degree can according to actual needs, and that is, the width according to actual in-situ layer is arranged；During form removal, contra rotating screw, its end is from sleeve After middle back-out, screw rod is extracted out from sleeve pipe.It is arranged such, on the one hand can shorten the length of sleeve, material-saving, simultaneously Be conducive to the dismounting of screw rod.Certainly, the diameter of described sleeve pipe should be moderate, can neither be too little, leads to after such casting concrete Screw rod is not easily taken out, nor too big, leads to leave larger cavity in in-situ layer.
Further, described screw rod is provided with trapezoidal thread, and described nut is used cooperatively with described trapezoidal thread.Trapezoidal thread Pitch larger so that nut can quickly spinning in and out, greatly accelerate die-filling form removal speed；In addition, acme thread is fitted Answering property is good, the trapezoidal tooth of big pitch and make cleaning mud thereon become convenient.
Further, described nut is to lengthen nut.On the one hand the setting lengthening nut easily opens up and screw rod upper trapezoid screw thread The steep-pitch thread using cooperatively, on the other hand big with the contact area of screw rod, it is difficult in the vibration processes of casting concrete By the pine that shakes.
Further, described screw rod is provided with pad.Certainly, for reaching more preferable effect, pad can be increased as far as possible Surface area.
Further, described pad is arranged between described sleeve pipe and nut.
Further, described sleeve is provided with anchoring piece.It is arranged such, anchor force in building element for the sleeve will be increased, During preventing to pulling process, sleeve is extracted in building element.
Further, described nut is wing nut.It is arranged such, manually the both wings of rotation butterfly nut can be to right Drawing device is fastened, and simplifies operation.
Further, described screw rod is connected by regular screw threads with described sleeve.So, by one end of screw rod and sleeve connection Be arranged to regular screw threads end, because precession socket end adopts regular screw threads, pitch little so that pull bar is difficult when cast-in-place because Want vibrated concrete and the pine that shakes.
Further, described screw rod is arranged to square toes or homalocephalus away from one end of sleeve.It is arranged such, square toes or homalocephalus are spiral shell Bar precession sleeve and tearing open provides impetus when thanking to back-out sleeve, you can be stuck on square toes or homalocephalus using spanner so that fill bar, Tear open and exert a force conveniently during bar, dismounting is rapid.The size of square toes or homalocephalus should be less than the size of screw rod so that nut can be from square toes End spinning in and out, easy to use.
Further, described screw rod is socketed with rubber seal plug between sleeve pipe and pad.It is arranged such, the setting of rubber seal plug Concrete slurry can effectively be prevented along the jack hole leakage of template.
