Description

Insulation anchoring screw

Technical field

The utility model relates to a kind of building insulating layer anchoring device, relates in particular to a kind of insulation anchoring screw.

Background technology

Insulation layer mainly plays the effect of house insulation, heat insulation and sound insulation, for guaranteeing building integral quality, the anchoring of insulation layer is except use cement mortar is pasted on body of wall by insulation layer, also need to use special anchoring piece by insulation layer and wall connecting in one, and the most frequently used anchoring piece is bar for line.

As China Patent No. " 01237844.5 " discloses a kind of bar for line, its open day is on 03 27th, 2002, its technical scheme is that described bar for line is comprised of expansion tube and center nail, the rear end of expansion tube is plate-like, the front end of described center nail is shaped with can be at the tapping screw thread of expansion tube centre bore tapping, and the front portion of described expansion tube has the axial groove of three above circle distribution.But take the prior art that this patent document is representative, in actual use, still exist following defect: while one, using this bar for line anchoring insulation layer, need through inserting the operation of expansion tube, center of rotation nail anchoring expansion tube in punching, hole, its anchoring process is complicated, causes efficiency of construction low.The degree of depth of punching and the insertion depth of expansion tube are all wayward simultaneously, and these extraneous factors cause the anchoring effect of insulation layer on body of wall poor; Two,, when insulation layer being installed on the loose class body of wall of non-densification, because body of wall density is loose, punching not only easily causes hole body of wall large area around to come off, and also easily causes hole internal diameter excessive, thereby affects the stability of insulation layer on body of wall; Three, due to when the anchoring insulation layer, need on body of wall, punch, so this bar for line is not suitable for as on the thin wall bodies of wall such as hollow foam brick wall body, PVC plastic hollow brick body of wall, gypsum board wall, wooden body of wall, color plate wall body and the loose class body of wall of non-densification.

And for example China Patent No. " 201120447567.5 " discloses a kind of monolithic building insulating layer fuel gas shooting nail anchoring piece, its open day is on 07 11st, 2012, its technical scheme is that described anchoring piece comprises anchor disc, anchor rod and fuel gas shooting nail, described anchor disc and anchor rod integral molding are an integral body, anchor rod is hollow structure, and fuel gas shooting nail is positioned at anchor rod.But the anchoring piece in this patent is applicable to the hard class body of wall that density is thicker more, when this anchoring piece being used for to thin wall body of wall and the loose class body of wall of non-densification, body of wall is little to the extruding force of nailing, the pulling force that nailing be can bear is also less, nailing is easily loosening, causes the anchoring effect of insulation layer poor.

Utility model content

The purpose of this utility model is to overcome the above-mentioned problems in the prior art, and a kind of insulation anchoring screw is provided, and the utility model can be anchored at insulation layer on the loose class body of wall of thin wall body of wall and non-densification rapidly, can significantly improve efficiency of construction.

For achieving the above object, the technical solution adopted in the utility model is as follows:

An anchoring screw, is characterized in that: insulation button and the screw that is positioned at insulation button, consist of, during anchoring insulation layer, insulation button is by screw and wall connecting, and one end of screw is stretched in body of wall, and the other end is positioned at insulation button.

Described screw is tapping screw or self-tapping screw, is provided with Gao Ya and low tooth on screw.

On described high tooth and low tooth, be provided with the V-shaped groove for anti-back skating, and on high tooth, the quantity of V-shaped groove is at least two, on low tooth, the quantity of V-shaped groove is at least two.

The nut of described screw is outer six square nuts or circle nut, during for circle nut, is provided with cross recess on nut.

Employing the utility model has the advantage of:

One,, in the utility model, insulation button need not enter body of wall, only need to insulation button through insulation layer, then the screw in insulation layer is clamp-oned to body of wall just can anchoring insulation layer, not only simplified construction technology, also significantly improved efficiency of construction; Adopt screw anchoring insulation layer rapidly simultaneously, can not cause again the body of wall that density is loose to come off, the degree of depth that can also enter by changing screw body of wall regulates the fastness of anchoring piece on body of wall, guarantees the better reliability of insulation layer on body of wall; Compare for the prior art of representative with China Patent No. " 01237844.5 " and " 201120447567.5 ", the technical scheme that the utility model is applied to insulation layer anchoring field by existing screw is that a kind of of original technology supplemented, and adopt after this technical scheme, the anchoring effect of insulation layer on thin wall body of wall and the loose class body of wall of non-densification is better, efficiency of construction is higher, and the technique effect that can reach is also more reliable.

Two, in the utility model, described screw is tapping screw or self-tapping screw, while adopting tapping screw, this anchoring piece is applicable to as thin wall bodies of wall such as wooden body of wall, Plastic body of wall, color plate wall bodies, self-tapping screw is applicable to class body of wall as loose in non-densifications such as hollow foam brick wall body, PVC plastic hollow brick body of wall, gypsum board walls, during construction, can select according to the body of wall of unlike material the anchoring piece of different screws, applied widely, not only construct more convenient, also help raising efficiency of construction; On screw, the high tooth of different-diameter and low tooth match, and can either improve the pulling capacity of screw, can prevent screw loosening again.

Three, in the utility model, V-shaped groove is set on Gao Ya and low tooth and can plays quick cutting into body of wall and chip removal effect, also have and prevent from exiting effect simultaneously, can prevent that screw from coming off in thin wall body of wall or the loose class body of wall of non-densification, makes the fastness of screw on body of wall better; And two V-shaped grooves are at least set on high tooth, and two V-shaped grooves are at least set on low tooth, can further improve the reliability of screw and wall connecting, be conducive to improve the anchoring effect of insulation layer.

Four, in the utility model, the nut of described screw is outer six square nuts or circle nut, during for circle nut, is provided with cross recess on nut, and this structure is convenient to by automatic screwdriver, screw be clamp-oned in body of wall fast, is conducive to improve efficiency of construction.
