Description
Technical field
The utility model belongs to building implement technical field, and in particular to a kind of Screw arbor with nut at both-ends and to drawing device.
Background technique
Currently, in the cast-in-place concrete construction of building, the cast-in-place node of exterior wall usually other than page board as exterior sheathing, with
To draw ring as inner template, then carried out using Screw arbor with nut at both-ends device to connection is drawn, traditional Screw arbor with nut at both-ends is integral type knot
Structure, after concrete cast-in-situ, not only screw rod can not be taken out, but also the screw rod for stretching out wall outer side influences the disassembly of template, needs
The part of exposing surface is sliced off, great deal of steel is wasted, and cannot reuse, wastes manpower financial capacity.In assembled
It in construction, outer page board and is strained and fixed between draw ring with general Screw arbor with nut at both-ends, according to draw ring when prefabrication
Arrangement is embedded with embedded sleeve barrel in outer page board, still, due to the error of prefabricated components production, embedded sleeve barrel often occurs
Positional shift occurs, or to the situation of draw ring position of opening mistake, will lead to Screw arbor with nut at both-ends can not normal mounting so that
It is inadequate to the supporting point of draw ring, thus generate run mould or rise mould the phenomenon that.Amelioration method commonly used in the prior art is basis
Existing embedded sleeve barrel position carries out live aperture again to aluminum alloy pattern plate, this will lead to working-day claims, increase construction cost.
In conclusion it is urgent to provide one kind can reduce cost, the Screw arbor with nut at both-ends of construction efficiency is improved and to drawing device.
Utility model content
The purpose of this utility model is that one kind can reduce cost, improves the Screw arbor with nut at both-ends of construction efficiency and to drawing device.
Above-mentioned purpose is to be achieved through the following technical solutions: a kind of Screw arbor with nut at both-ends, including screw body, the screw body
One end it is tapered and be socketed with fixing piece, the screw body can be along the axial movement of the fixing piece, and the fixing piece can
The growth of the length protruded into fixing piece with screw body and expand modification.
The utility model be mainly used in the prior art in drawing device installation process embedded sleeve barrel occur positional shift or
To the situation of draw ring position of opening mistake, during specifically installing and using, the position benefit to the hole in draw ring can be compareed
The size of the aperture on wall with electric hammer, aperture should be bigger compared with the outer diameter of screw body, and screw body is sleeved and fixed the one of part
It holds in the hole opened up together with fixing piece insertion wall, rotates screw body, screw body protrudes into the growth of the length in fixing piece,
Section diameter of the screw body in fixing piece becomes larger, and fixing piece expansion modification, which is tightly embedded in, is anchored at walls concrete knot
Within structure, Screw arbor with nut at both-ends is fixed on the wall；When finishing and remove to draw ring wait pour, screw rod sheet only need to be reversely twisted
Body can then be such that screw body removes from wall, and fixing piece then stays in wall, be enclosed concrete structure when repairing wall
It is interior.The utility model structure is simple, as when to drawing device can not normal mounting when interim remedial measure, cost is compared to existing
There is the amelioration method in technology to substantially reduce, while improving construction efficiency.
Further technical solution is that the fixing piece includes spring, pitch and the hand of spiral difference of the spring
Match with the thread pitch and the hand of spiral of the screw body.In this way, screw body is matched with spring, it is rotation with spring
Inbound path, with going deep into for screw body, section diameter of the screw body in spring is become larger, and spring gradually expands
Deformation, tightly insertion is anchored within walls concrete structure.
Further technical solution is that the fixing piece further includes the baffle that the spring top is arranged in, the gear
The side wall of plate touch the screw body.So set, more going deep into fixing piece with the rotation of screw body, screw body
It is bigger to the extruding force of baffle, in this way, the frictional force of baffle and concrete wall is bigger, tightly it is embedded within concrete structure,
On the one hand it can play the role of fixed spring at the initial stage that screw body rotates, spring is avoided to rotate together with screw body,
On the other hand the frictional force for working as screw body insertion certain depth rear baffle and concrete wall is very big, greatly increases fixing piece in wall
Intracorporal anchor force improves the anchor force of Screw arbor with nut at both-ends.
Further technical solution is that the fixing piece is to set internal thread sleeve, and the sleeve is equipped with reduction mouth.
So set, section diameter of the screw body in sleeve becomes larger as screw body gos deep into sleeve, sleeve is squeezed
Pressure is bigger, and sleeve is along reduction mouth dilatancy, and tightly insertion is anchored within walls concrete structure.
Further technical solution is that the one end of the screw body far from fixing piece is square toes or homalocephalus.Square toes or
Homalocephalus for Screw arbor with nut at both-ends precession fixing piece and disassembly screw out fixing piece when impetus is provided, it can using spanner be stuck in square toes or
On homalocephalus, so that force is convenient when filling bar, tearing bar open, dismounting is rapid.
To achieve the above object, the utility model provides also a kind of pair of drawing device, including any of the above-described described to drawing spiral shell
Bar, the Screw arbor with nut at both-ends, which is worn, is connected to casing, and the Screw arbor with nut at both-ends is equipped with fastening nut.In the mistake that the utility model is installed and used
Cheng Zhong, in the hole that the Screw arbor with nut at both-ends precession wall that screw rod is socketed with casing is opened up, to solid with fastening nut after draw ring installation
Solid plate.The length of described sleeve pipe can be arranged according to the width of practical in-situ layer according to actual needs；It is reversed to revolve when demoulding
Turn Screw arbor with nut at both-ends, after end is screwed out out of wall opens up hole, screw rod is extracted out from casing.So set, advantageous
The disassembly of rear Screw arbor with nut at both-ends is poured in concrete cast-in-situ layer.Certainly, the diameter of described sleeve pipe should be moderate, can neither be too small, this
Screw rod is caused to be not easily taken out after sample casting concrete, can not be too big, cause to leave biggish cavity in in-situ layer.
Further technical solution is that the Screw arbor with nut at both-ends is equipped with gasket, and the gasket setting is in described sleeve pipe and tightly
Gu between nut.Gasket reaches better effect, can increase the surface area of gasket as far as possible.
Further technical solution is that the Screw arbor with nut at both-ends is between fixing piece and casing and between gasket and casing
It is socketed with rubber seal plug.So set, on the one hand the setting of rubber seal plug can effectively prevent concrete slurry to connect along wearing for template
On the other hand hole leakage can prevent concrete slurry from penetrating into being not easy to screw out when causing Screw arbor with nut at both-ends to be dismantled in described sleeve pipe.
Further technical solution is that the Screw arbor with nut at both-ends is equipped with sealing part.The setting of sealing part can prevent coagulation
Moisture in soil paste liquid penetrates into inside wall along Screw arbor with nut at both-ends.
Further technical solution is that the fastening nut is wing nut.So set, by can be manually rotated butterfly
The both wings of nut can be fastened to drawing device, simplify operation.
