Description

A kind of to drawing device
Technical field
This utility model belongs to building implement technical field, particularly relates to a kind of to drawing device.
Background technology
At present, in the cast-in-place concrete construction of building, the most all can use Screw arbor with nut at both-ends device.Tradition Screw arbor with nut at both-ends be integral type structure, after concrete cast-in-situ, not only screw rod cannot take out, and stretches out The screw rod of wall outer side affects the dismounting of template, needs to slice off the part of exposing surface, wastes great deal of steel, And can not reuse, waste manpower financial capacity.
For solving above-mentioned technical problem, in prior art, disclose dismountable Screw arbor with nut at both-ends, such as patent CN 202483175 U disclose a kind of detachable Screw arbor with nut at both-ends, described detachable Screw arbor with nut at both-ends include inner screw, Connector, external screw rod, chevron card and clip, the two ends of wherein said inner screw are respectively by described connection One end of part and described external screw rod connects, and the other end at described external screw rod connects described chevron card and described Clip, described clip is arranged on the outside of described chevron card.Above-mentioned Screw arbor with nut at both-ends can be dismantled and can Recycling, has saved manpower financial capacity.But, owing to connector is against interior template, pouring complete form removal After, connector has one side and exposes in-situ layer, causes wall surface unsightly.
In sum, need badly exploitation a kind of dismounting after do not affect in-situ layer metope attractive in appearance to drawing device.
Utility model content
The purpose of this utility model be to provide a kind of dismounting after do not affect in-situ layer metope attractive in appearance to drawing device.
Above-mentioned purpose is to be achieved through the following technical solutions: a kind of to drawing device, including the first screw rod, second Screw rod and connector, one end of described connector is connected with the first screw rod, and the other end and the second screw rod pass through spiral shell Stricture of vagina is flexibly connected, and one end that described connector and the first screw rod connect is provided with keeper, on described second screw rod It is provided with nut.In order to ensure after casting concrete, concrete will not wrap the second screw rod, it is desirable to connects The end of part, against interior template, arranges keeper in the end of connector, in use, and keeper End face replaces the end face of connector, and the face area of keeper, less than the face area of connector, works as in-situ layer After having poured, so it is effectively reduced and drawing device is spilt the area on in-situ layer metope, solve metope Inaesthetic technical problem.Certainly, in the case of not affecting use, the face area of keeper the least more Good.During it should be noted that this utility model uses as exterior wall is cast-in-place, in the prefabrication process of wallboard, The end anchorage of described first screw rod is in wallboard；Template in arranging parallel two piece, pours mixed in the middle of it In the case of solidifying soil, described first screw rod stretches out one of interior template, and uses nut to fasten.
Further, described keeper includes that at least one is protruding.Being arranged such, projection can play position-limiting action, Making connector not expose outer surface, the most multiple points expose simultaneously, and the most protruding length can be done short as far as possible, Make to only have therebetween a small amount of laitance so that the second screw rod is easily disassembled.Described projection is preferably symmetrical arranged 2 to 3 Individual.
Further, described keeper is along the circumferentially disposed bulge loop of connector.It is arranged such, only the circle of bulge loop Ring exposes at concrete surface, and bulge loop can make it in do not have concrete to penetrate into, make the second screw rod can be light Demolition is unloaded.In the case of not affecting use, the wall of bulge loop is the thinnest, and internal diameter is the least, when So its internal diameter have to be larger than the diameter of the second screw rod.
Further, described connector and the first screw rod are flexibly connected by screw thread.It is arranged such, it is simple to regulation Connector and the relative position of the first screw rod so that connector can be adjusted its one end rear against interior template.
Further, described connector and the first screw rod connect one end and the one end being connected with the second screw rod are offered Hand of spiral contrary.When installing and using, can first regulate the relative position of the first screw rod and connector, the company of making Fitting and interior template have certain distance, described connector and one end of the first screw rod connection and connect with the second screw rod The hand of spiral that the one end connect is offered is contrary, then after the second screw rod is screwed into connector, after being screwed to termination, then Continue to twist and then can move towards the direction of the second screw rod by band follower link, until the adjacent interior template of connector. So, after in-situ layer completes to pour, owing to connector is close to interior template, therefore the second screw rod can't occur The phenomenon of concrete parcel, when removing the second screw rod, it is only necessary to it back-outed from connector.
Further, described first screw rod is provided with sealing part.The setting of sealing part can prevent water along to drawing spiral shell Bar penetrates into inside body of wall.
Further, described nut is butterfly nut.It is arranged such, manually rotates the both wings of butterfly nut Can fasten to drawing device, simplify operation.
Further, described first screw rod is provided with anchoring piece away from one end of connector.It is arranged such, can will set The one end having the first screw rod of anchoring piece is anchored in building element, increases anchor force, prevents pulling process During, the first screw rod is extracted in building element.This kind of situation is applicable to building element to be made as template Situation.
Further, described second screw rod is provided with pad.Certainly, the surface area of pad can be increased as far as possible.
Further, described pad is between described nut and connector.
Further, described second screw rod is provided with hold-doun nut.It is arranged such, when can be the second screw rod dismounting There is provided impetus, it is simple to the dismounting of the second screw rod.
Further, described hold-doun nut and the second screw rod removably connect.It is arranged such, it is simple to tearing open of nut Unload and move, also allow for transport simultaneously.Certainly, described hold-doun nut may also be butterfly nut.
Further, described hold-doun nut is fixed on described second screw rod one end away from connector.Preferably, may be used Being arranged to square by the termination of the second screw rod, the endoporus of described hold-doun nut is also configured to and the second screw end head The shapes and sizes matched.
Further, described second screw rod is arranged to square away from one end of connector.It is arranged such that Two screw rods are arranged to square toes or homalocephalus, such square toes or homalocephalus offer stress point, just away from one end of connector Dismounting in the second screw rod.
