Description of the invention (/) According to the preamble of item 1 of the patent application scope, the present invention shows a fixing element with a fixing device arranged at its rear end for clamping object. DE-OS 2 9 1 4 7 3 9 discloses a fixing element having an expansion area in the area of its front end surface, which is formed by a longitudinal groove having a bottom that slopes upward toward the front end, and the expansion element is inserted In longitudinal slot. The anchoring effect of this fixing element causes the handle to move axially to the expansion element that is stuck in the wall of the hole because the object to be fixed is clamped in the building part after the handle is driven into the pre-reinforced hole in the building part . Because the bottom of the longitudinal groove receiving the expansion element slopes upward, the expansion element is radially squeezed outward, and as a result, the fixing element is wedged into the hole. However, the disadvantages of fixed elements are known. The reason is that the expansion element has teeth on its outer surface, which form a straight edge protruding beyond the handle to traverse to the longitudinal direction. The rim occupies the entire width of the expansion element and exhibits high resistance because the fixing element is driven into the construction component; in particular, in the case of a construction component composed of concrete, it does not contribute to the ease except for the high resistance to driving In combination, this resistance can cause damage to the fixing element, which damages the anchoring effect. Furthermore, the expansion element scrapes material from the inner wall of the borehole during the drive-in operation. The collection of this material in the longitudinal groove may cause the expansion element to become stuck in the longitudinal groove. As a result, the displaceability of the expansion element in the longitudinal groove is damaged to such an extent that when the reaming hole is expanded due to the formation of cracks, it cannot be expanded subsequently after the anchoring operation. Because of this disadvantage, conventional fixing elements are not suitable for use in tensile zones where cracks occur. Even in crack-free concrete, it is not suitable for the tensile zone and another reason for its relatively low fixed value is that in conventional fixing elements, facing the fixing element, the paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 Mm) IT n Λ —.—;-I — ^ 装 ------ 訂 ------ 1 (Please read the precautions on the back before filling out this page) Employee of Central Bureau of Standards, Ministry of Economic Affairs Printed by the consumer cooperative A7 B7 5. Description of the invention (>) The longitudinal groove at the front end is limited by a stop face. As a result, on the one hand, only the retraction angle of the bottom of the longitudinal groove can be obtained, and on the other hand, the length of the expansion element must also be considerably shortened for the longitudinal groove in order to obtain a satisfactory anchor positioning movement. In addition, if the widening of the reaming occurs further as a result of crack formation, there is a risk that the expansion element will stop against the face before the longitudinal groove without providing any possibility of further expansion. This situation may also occur, for example, when preparing holes, the pre-drilled holes for fixing the components become slightly larger than desired. Finally, the flat bottom of the longitudinal groove and the flat seating surface of the expansion element provide high contact pressure during the expansion process that can lead to cold welding. As a result, the back entanglement expands and thus the applicability to the stretched area is also hurt. DE 3 3 3 4 7 5 4 C2 discloses an expansion plug, the plug body of which has a sleeve-shaped structure with internal threads for screws or screws. The wedge-shaped expansion element of the expandable plug is part of the plug body, and is joined to the plug body with a web remaining between the cuts and acting as a break point. On the one hand, the cutout configuration causes the inclined surface to be inclined upward toward the front end of the plug body, and on the other hand, it forms a wedge shape of the expansion element. In order to provide a surface for the application of the expansion tool, the stop member protruding into the inner hole of the sleeve of the plug body is integrally formed on the expansion element. To anchor the expandable plug, the expansion element first tears off at the desired breaking point with the expansion tool, and then moves to the front end of the plug body. Only the tearing of the desired breaking point requires a thrust force, which requires the conventional expandable plug to be supported at the bottom of the borehole. Moreover, the notch bridging the two sliding surfaces of the separating plug body and the expansion element requires a large axial direction of the expansion element -4-This paper scale is applicable to the Chinese National Standard (CNS) A4 specification (210X297mm) | _IL --- ---- Agriculture ------ Order (please read the notes on the back before filling in this page) A7 B7 printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs 5. Invention Instructions (4) Displacement in order to obtain expansion . Therefore, further, the expansion element and the plug body are composed of the same material, so there is a danger that, during expansion, the two sliding surfaces will be damaged by cold welding and joining, so that post-expansion expansion will not occur. Therefore, the conventional expansion plug is not suitable for the stretched area where the hole will be widened due to the formation of cracks, which needs to be compensated by post-winding expansion. Therefore, the basic problem of the present invention is to improve the type of fixing element described in the introduction, so that the fixing element can be driven in with little resistance, and can be anchored in the construction component in a simple manner, even when the borehole is widened due to the formation of cracks, It has a high fixed value due to excellent post-mine expansion behavior. This problem is solved by the pending matter mentioned in item 1 of the patent application scope. Longitudinal grooves with a trapezoidal cross-section and made by stamping provide sliding surfaces arranged at an angle to each other, which have been pressed at this surface. Because the expansion element displaces in the longitudinal groove during expansion, the compression promotes sliding behavior, so the reduction tends to cold weld and join. A further reduction in the tendency to engage is obtained by reducing the contact pressure by the fact that the two sliding surfaces are arranged at an angle to each other, while also taking over the lateral guidance of the expansion element during its displacement. Since the teeth are arranged at the outer surface of the expansion element and part of the height protrudes beyond the roof-shaped structure of the handle, when the fixing element is driven in, only one groove is scraped out in the prepared drilling hole. Because only the apex of the tooth-shaped expansion element snaps into the wall of the borehole, the resistance that must be overcome when the fixing element is driven into is low. After being driven in, the teeth arranged on the expansion element fix it in the hole, and during the anchoring process, the handle displaces the expansion element axially -5- This paper size applies to the Chinese National Standard Falcon (CNS) A4 specification (2 丨 0 '297mm) -----: --- {Λ 衣 ----- Γ-1Τ (Please read the notes on the back before filling this page) 300273 at B7 Description of the invention (4) Printed by the Ministry of Economic Affairs, Central Bureau of Standards, Employee Consumer Cooperatives. The half of the watch piece with the small end length and the bottom part, not the part, is compared with the tooth surface of the edu piece before the tooth is set and the anchor is formed by the support of the surface. At the top of the area, the fixed diameter circular pole tau expansion teeth can be added to the roof edge to support the straight grooves with UI expansion and coextrusion. ? Without pressure into the external force, the angle is two-way, and its hand piece is convex, so that the force-directed anti-screw handle is longitudinally finished.

Description of the invention (,) In the further construction of the present invention, in order to facilitate driving in, the ramp-shaped slope extends to the first tooth The tip of the part may be arranged at the front end of the expansion element. In a further construction of the invention, the fixing element may have an internal thread at its rear end, so that a fixing element anchored in the brick by an object can be fixed by screws, screws or the like. The weight acting on the plug body produces a complete displacement between the plug body and the fixed expansion element, and the displacement causes the expansion to be strengthened due to the obliquely upward bottom of the longitudinal groove. Because of the good sliding properties of the sliding surface, even when the reaming hole is widened due to the formation of cracks, the axial displacement occurs between the expansion element and the plug body. In some cases, the plug body is undesirable for the displacement of the expansion element, because this also causes displacement of the screw and screw. To avoid this displacement, in another advantageous configuration, an inner hole is provided which extends through the stop shoulder into the longitudinal groove, and abuts the internal thread with its partial cross-section and its intersection, and expands the element It can be moved to the front with screws, screws or driving tools to anchor the fixing element. Between the expansion element and the screw or screw to be screwed in, an elastic element, preferably a compression spring, may be further arranged. The elastic bias of the expansion element causes the expansion element to be pushed up when the crack is formed to widen the reaming hole, so that no axial displacement of the plug body is required to expand the expansion. Rubber bolts can also be used as elastic elements. The present invention is illustrated by the embodiment shown in the drawings, wherein: FIG. 1 shows a fixing element with an expansion element placed in a longitudinal groove in its expansion area, and it is inserted into a hole in a construction component; FIG. 2 is Figure 1 is a partial longitudinal section of the fixing element in its anchoring position.

Invention description (s ) The screw 34 shown in FIG. 5, for example, is used to suspend pipes, ceilings, and the like, and is screwed into the internal thread 30 of the fixing element lb. The compression spring 35 is arranged between the expansion element 6 and the screw 34 as an elastic element. The compression spring 35 can be pushed in and clamped by the screw 34 after the fixing element 1b is anchored with a driving tool, or the screw 34 can be used directly for the axial displacement of the expansion element 6. After the screw or screw is screwed in, the compression spring exerts a steady pressure on the expansion element 6, so that on the one hand, the expansion element 6 is pushed upward when the hole is widened due to the formation of a crack, and on the other hand, it provides the prevention of the screw 34 Protection of Vibration >> The expansion element 6 can be pressed or cold-formed with a die and a bending die and made of malleable iron. The expansion element of malleable cast iron has good sliding properties because of the graphite component in malleable iron.
