The body of the staple is from the material on the plate, which comprises a piercing end of one of the thin plates, and the ring is extended to the temple adjacent to the collar. Pieces (usually screws) to be fixed:: Threaded holes to accommodate - the core includes - external large width threads, because: "Locked onto the plate... on the plate # This is drilled in the holding plate After that, the thread is tied into the thread in the slab. The element: solid: the purpose of the nail is to locally strengthen the fragile material so that the lock member 70 is fixed. EP 01 65674. This document is intended to include a needle that is substantially flat and has three teeth. This combination can be split and expandable and can be expanded by a fastener. 'The thickness of the plate in which it is staggered is smaller than the length of the staple. The expansion described herein refers to the stapled foot due to the slit on the outside of the plate (as the opposite side of the support of the staple collar) The separation between the actions is generated. An example of such an expandable 200912150 staple for fragile materials is known from US 2006/012082, the drilled end of which is always flat and its system split in the diametrical direction; its disadvantage is that its expansion is limited to narrow The seam planes are orthogonal. Accordingly, the applicant of the present invention has proposed an invention for promoting the expansion of such a staple having a split body for a fragile material. SUMMARY OF THE INVENTION The present invention therefore relates to an anchoring dowel for a frangible material, comprising: a body extending from a holding collar to a bore end, the body being drilled in the axial direction The hole has a thread to accommodate a locking member, the body includes a threaded and supporting external thread, and the body can be split from its drilled end to its supporting collar, characterized in that The staple body includes an expansion slit that extends along a plurality of secant faces along the length of its axis. With such a configuration, when the lock is introduced, a circular shape is formed which is concentric with the shaft. The technical result of this circular expansion is combined with the results of the non-coplanar results obtained from the complex number of drilled teeth. In a preferred embodiment of the staple according to the invention, the body wall comprises three angular equidistant expansion slits which in effect ensure a circular expansion. Preferably, the drilled end of the body is longitudinally recessed to reveal a cutting edge, two of which are provided to the expanding slit, and preferably one of the two cutting edges adjacent to a slit is Toothed to make the shredding of fragile materials easier. 6 200912150 [Embodiment] The staple to be described now comprises a substantially cylindrical body 1 having a shaft 2 and extending from a holder collar 3 to a drilled end 4. The body 1 comprises two parts, the first part 5 being a cutting part extending from the drilling end 4 to the collar 3, and the second part 6 being an anchoring and supporting part extending from the collar 3 to the drilling end 4 . In the illustrated example, the cutting (leg) portion 5 extends substantially more than 40% of the length of the staple. The body 1 is drilled with a shaft hole 7 and the shaft hole 7 is adapted to accommodate a member for locking a component to the wall panel, wherein the staple is then anchored to locally strengthen the wall frangible material. And precisely lock the part in it. The shaft hole 7 extends substantially beyond the length of the anchoring and supporting portion 6 of the staple body, but actually extends in the leg portion 5 with a very thin axial piercing 8 until the drilled end 4 Thus, it is produced in the slit 9-11 in the body of the staple. The anchoring and supporting portion 6 of the staple body has a threaded and supporting external thread 12 which has a very large width in the vicinity of the collar 3 but has a larger vicinity of the leg portion 5 of the staple body Small width. After the anchor has been anchored, in order to provide compression to the hard plate on the side of the wall, the thread 12 is close to the collar 3 at a distance below the pitch. The width of the thread 12 in the vicinity of the collar is substantially equal to the radius of the configured cylindrical portion 6 of the body to ensure that the staple is screwed in and supported well. The body wall of the staple body is axially split from the bore end 4 to a relatively small distance (in this case, substantially 3 d) from the collar 3, along the three secant axis planes. Split open to provide three angular equidistant expansion slits 9, 7 200912150 1 0 and 1 1 . The leg portion 5 of the staple body has a longitudinal depression after three dihedrals to form three pairs of parallel cut sheets 1 3 -1 8 which are bounded by the expanded slit '9-11 Adjacent (13, 14; 15, 16; 17, 18), and two two, different pairs of ground (13, 18; 14, 15; 16, 1 7) with three teeth respectively formed and slit 9, 1 0, 11 adjacent three extended feet 3 1 , 3 2, 3 3 . The edges 1 9 - 2 4 parallel to the axis 2 of the sheets 13 - 18 form a cutting edge, and one of the two edges of the adjacent sheets of the pair of slits (1 9 , 2 1 , 2 3 ) is toothed . The end of the cutting sheet is cut into the form of drilled teeth 25, 26, 27, which are adjacent to the perforations 8 of the fastener; all three teeth are arranged in a circle shape. Due to the expansion of the slit, the thread 12 is interrupted at some point 40 along the slit to provide a planar radial surface for improved cutting. The staples disclosed above may be made of plastic or metal. The following describes the use of the staples. If necessary, provide a locking threaded perforation for the part to be secured to the wall. This system uses a self-tapping dowel and drives the staples through a rotary drive tool and a template 30 disposed in the collar 3, which is generally a Phillips type. ( Phillips type ) external stencil, the slab hard sheet is first drilled with its drilling teeth 2 5, 26, 27 by the drilling end 4, after the drilling operation, the thread 12 starts to the wall The sheet material acts to engrave the material inside and anchor the staples until their shaft 8 200912150 ring 3 abuts the hard sheet; the sheet remains pressed between the collar 3 and the thread 12 and may be slightly Protruding toward the bore end 4. The leg portion 5 having three extension legs 3 1, 3 2, 3 3 protrudes from the other side of the wall panel. Once the staple is anchored into the panel, the component that is locked therein is positioned and inserted into the shaft bore 7 by a locking screw that is screwed in and passed through the collar 3. Once the end of the screw enters the leg portion 5 of the protruding pin on the outside of the panel, it expands the staple and separates all three extension legs 3 1 , 3 2 , 3 3 , which perfectly surrounds the staple Around the shaft 2, the staples are perfectly joined to the wall. Obviously, the screw should be screwed in until its head effectively presses the part against the wall.
