Abstract

The utility model relates to an architectural hardware material, concretely relates to wall body and wall connection's self -tapping screw, including the head of a nail, nail body, screw tail, its characterized in that: the nail body have fine screw thread, screw tail become the point by nail body convergent, the head of a nail for horn mouth form, the tip sets up the cross and sinks the groove, the neck sets up a plurality of grinding grain. Furthermore, grinding grain salient be three pyramid -shaped in the shape of neck. Compared with the prior art, the utility model discloses the neck sets up a plurality of grinding grain, becomes wall plates surface grinding the powder and carrys over out of when head of a nail rotation is followed to the grinding grain, and within the head of a nail immerse wall plates very easily, efficient, required electric tool power was little, strip silk phenomenon can not appear.

Description

The tapping screw of a kind of body of wall and wall connecting

Technical field

The utility model relates to building five metals material, is specifically related to the tapping screw of a kind of body of wall and wall connecting.

Background technology

Along with social development, country carries out wall reform policy, to realize the object protecting soil, save energy. the novel wall material kind occurred in society in recent years gets more and more, wherein apply more, have gypsum or cement light partition wall board, color steel, air-entrained concrete building block, steel wire net rack cystose, small concrete block masonry, plasterboard, gypsum block, figuline building blocks, sintered perforated brick, shale brick, solid concrete brick, the big plate of PC, lateral aperture concrete panel, gac body of wall, the novel partition plate of PIC etc. it is simple that these type materials have assembling, easy construction, raise the efficiency, duration is short, shock resistance is good, planeness height, attractive in appearance, do not rely on agent structure to install, versatility and generalization are good, security height etc. plurality of advantages, but the research and development of the installation five metals supporting with it does not catch up with the tempo of novel wall sheet material, the screw that such as existing body of wall and wall connecting are fixed is in assembling process, the head of a nail is not easy to sink within wall board, intensified pressure goes to twist by force, materials for wall can be squeezed into powder thus strip silk by screw thread, lose the effect of being connected and fixed, in order to the head of a nail is sunk within wall board, need to bore a tapered hole in advance and it is used for sinking to of the head of a nail, efficiency is had a greatly reduced quality.

Practical novel content

The purpose of this utility model is to solve the above-mentioned technical problem of prior art existence, it is provided that a kind of Novel precast floor slab.

The technical solution adopted in the utility model is:

The tapping screw of a kind of body of wall and wall connecting, comprise the head of a nail 1, nail body 2, nail tail 3, it is characterized in that: described nail body 2 is with Thury thread, described nail tail 3 is apered to point by nail body, the described head of a nail 1 is bell mouth shape, end arranges cross deep gouge 11, and neck arranges some grinding grains 12.

Further, it is triangular pyramidal that described grinding grain 12 protrudes from the shape of neck.

Compared with prior art, the utility model neck arranges some grinding grains, when grinding grain rotates with the head of a nail, wall board surfacing is become powder and takes out of, the head of a nail is easy to sink within wall board, efficiency height, required power tool power is little, there will not be strip silk phenomenon.
