Definitions

  • the present invention relates to a drilling anchor according to the preamble of claim 1.
  • Such drilling anchors are made of fiber-reinforced plastic, wherein fibers extending both in the longitudinal direction of the drilling anchor and fibers running obliquely to the longitudinal direction of the drilling anchor are embedded in a plastic matrix.
  • the drilling anchors are provided with a central channel which is formed by an axial bore extending over the entire length of the drilling anchor.
  • Drilling anchors are also well known as so-called "self-drilling" anchors (SB anchors). They are mainly used in mining or tunneling to secure components such as ceilings or walls. In particular, they are used when rock, mountains or rocks are brittle and the anchor well is so unstable that it collapses during drilling or after pulling the conventional drill string and a conventional anchor can not be set.
  • the drilling anchors combine the function of the drill string, which conventionally in connection with a percussion or rotary drilling machine drilling holes, with the function of the subsequently inserted into the drilled holes anchor, so that the extraction of the drill string and the breaking of the borehole wall can be avoided can.
  • the drilling anchors are provided at the front with a drill bit and connected at the back with a drill or drilling device.
  • Fiber-reinforced plastics are fiber composites in which the plastics are combined with fibers made of a different material in order to obtain positive synergy effects and improved in the desired direction, in particular mechanically improved properties of the plastic.
  • a plurality of parallel oriented fibers which may for example have a diameter of 10 to 30 microns, is thus surrounded by a matrix of plastic resin.
  • the fibers give the composite its high strength in the longitudinal direction, while the resin matrix serves to fix the fibers in their position while protecting them from harmful influences.
  • a multi-layered cable anchor in which a rope made of textile yarn is surrounded by a support braid and may contain an inner soul.
  • an outer protective sheath made of plastic is additionally provided.
  • such a cable anchor can not be used as a drilling anchor for the applications mentioned above, since apart from a missing external thread neither a transmission of high torques nor an effective transmission of impact energy of the hammer to a drill bit mounted on the anchor bit is possible. Rather, it is designed as a flexible anchor with its rope-like construction for tumbling as endless material, which can be introduced only in already completed holes.
  • a rock anchor made of plastic which consists of synthetic materials, which are arranged in superimposed layers.
  • the anchor can also be designed as a hollow anchor for injecting.
  • this rock anchor is also not suitable for drilling due to its lack of rigidity, since it is designed as a yielding system to withstand movements in sedimentary rocks and convergences, which is comparable to increased ductility in steel.
  • the rock anchor also has no external profiling or no external thread, so that it can not be used as a drilling anchor for this reason.
  • fiber reinforced plastic drilling anchors of the type mentioned above are from WO 96/21087 known as the closest prior art. They each have a limited axial extent at the two end regions thread. These drilling anchors include both helically wound fibers and longitudinal fibers.
  • a disadvantage of these known drilling anchors is only a limited composite effect in pressed concrete or other surrounding media or surrounding rock.
  • the loads occurring during drilling can lead to damage to the drilling anchors despite the two-layer fiber structure.
  • the object of the present invention is therefore to provide an improved drilling anchor of the type mentioned above made of fiber-reinforced plastic, which can better absorb the complex occurring stresses and resulting forces in drilling operation.
  • a multi-functional to be used anchor drill is provided, which has sufficient hydraulic strength for flushing with drilling water and the subsequent high-pressure injection at very high pressures and at the same time can compensate for the introduced into the anchor complex tensions and burdens in pre-destroyed rock.
  • a first fiber layer with fibers extending obliquely to the longitudinal direction of the drilling anchor is surrounded by a second fiber layer with fibers running in the longitudinal direction of the drilling anchor, such that the second fiber layer extends from at least one third fiber layer with an angle to the longitudinal direction of the drilling anchor Fibers is surrounded, and that the drilling anchor has a over its entire length extending thread, which is formed in at least one outer fiber layer of the drilling anchor.
  • the main advantage lies in the fact that a much more versatile Bohranker to be used is created, which ensures a permanently greater safety at a much higher load capacity.
  • the complex stresses and resulting forces occurring during the drilling process in particular drag forces from axial compression and torsion z. B. by Friction and cutting force are absorbed much better.
  • much higher hydraulic pressures when flushing with drilling water, but especially during subsequent high-pressure injecting z. B. with 2-K systems and pressures over 300 bar without damage to the drilling anchor are included and at the same time the complex introduced from tensile, shear and shear stresses and strains of the anchor in the rock can be compensated.
  • the drilling anchor according to the invention is inexpensive to manufacture and easy to handle with low weight with a simple design. In addition, an optimal corrosion protection is guaranteed even in long-term applications.
  • the third fiber layer is surrounded by at least one fourth fiber layer. It is particularly advantageous if the third fiber layer is surrounded by at least one fourth fiber layer. As a result, an even better strength and an optimized training of the drilling anchor can be achieved.
  • the first and / or third fiber layer comprises fibers which are wound helically at an angle between 30 ° and 60 °, in particular between 40 ° and 50 °, preferably at an angle of approximately 45 ° to the longitudinal direction of the drilling anchor are.
  • first and / or third fiber layers each comprise a first group of fibers which are wound at an angle of between 30 ° and 60 ° to the longitudinal direction of the drilling anchor in a first gradient orientation and also a second group of fibers , which are wound at an angle between 30 ° and 60 ° to the longitudinal direction of the drilling anchor in the opposite slope orientation.
  • the two groups of fibers can be introduced either separately in succession or mixed together.
  • the fibers of individual fiber layers are embedded in plastics which are different from the plastic of the adjacent fiber layers.
  • the fibers of individual fiber layers may consist of a material which is different from the material of the adjacent fiber layers.
  • the first and / or third fiber layer comprises fibers running obliquely to the longitudinal direction of the drilling anchor and embedded in vinyl ester resin.
  • the embedding of the inner channel limiting fibers in vinyl ester resin advantageously serves to increase the chemical resistance of the drilling anchor.
  • the second fiber layer with fibers extending in the longitudinal direction of the drilling anchor is preferably embedded in epoxy resin. They thus allow optimum transfer of tensile and compressive forces even with a pulse-like impact load.
  • the fibers of the first and / or second fiber layer are glass fibers.
  • the fibers of the third fiber layer are preferably carbon fibers.
  • the fourth fiber layer comprises glass fibers, which are preferably embedded in epoxy resin.
  • the thread can be formed without a fiber gate. In this way, a high-strength thread is achieved without cutting and thus without destroying the fibers, which produces an optimal composite effect to its environment at its length according to the invention.
  • the drilling anchor based on the volume, has a fiber content of at least 80% and a plastic resin content of at most 20%. In this way optimal strength values are achieved with regard to all occurring loads.
  • the thread of the drilling anchor is provided with a hardened protective coating.
  • the protective coating may consist of topcoating, in particular of a cured gel, and serve not only a mechanical protection, but also a UV protection and, in particular, an acid protection of the thread.
  • the present invention further relates to a method of making a drilling anchor of the type described above. Thereafter, the drilling anchor is pultruded in multiple layers with separate layers, thereby enabling cost effective and easy fabrication in spite of the improved properties of the drilling anchor.
  • the drilling anchor 1 shown in the figures consists of fiber-reinforced plastic, which is constructed in multiple layers.
  • the drilling anchor 1 has a continuous over its entire length axial bore 2 and also over its entire length continuous external thread 3 with a wavy contour.
  • the fibers or the groups of fibers are not only arranged in a parallel unidirectional manner but in particular wound in the uppermost layer opposite the thread rotation and drilling direction or embedded in the resin matrix.
  • two groups of glass fibers are embedded in a first fiber layer 4 with simultaneously high mechanical and chemical resistance in vinyl resin to increase the hydraulic stability. These two groups of the first fiber layer 4 are each wound at an angle of 45 ° to the axial alignment of the drilling anchor 1 in opposite directions.
  • a second fiber layer 5 of glass fibers is embedded in the longitudinal direction of the drilling anchor 1 in epoxy resin. It serves to accommodate high mechanical axial tensile and compressive forces.
  • carbon fibers are opposite to the rotation and drilling direction of the external thread 3 embedded in vinyl ester resin. They take over the special reaction forces from the drilling work. At the same time they provide permanent protection for the glass fibers in the core against external chemical effects due to the receiving vinyl ester resin.
  • the high-strength thread 3 is formed without destroying the continuous glass fibers.
  • the drilling anchor 1 is injected after drilling through various adapter systems.
  • cement mortar that is not critical because no high injection pressures and hardly reaction pressures occur, not mixed on or in the drilling anchor 1 high energy and pressure must be maintained and the borehole itself must not be kept consuming closed.
  • good sealing adapters with upstream valves, integrated mixer, nozzle and check valve must be used.
  • the anchor tube 1 itself must also be generally hydraulically loadable up to about 250 bar working pressure or nominal pressure (350 bar bursting pressure). This load capacity is achieved by the inventive design of the drilling anchor 1.
  • a self-drilling FRP anchor 1 for right-handed rotatory drilling has a limited torsional resistance, in contrast to steel pipes due to the anisotropy of the fiber composite.
  • the drilling anchor according to the invention is optimized with regard to resin quality and fiber quality as well as fiber orientation and process.
  • both one or more unidirectional fiber courses 5 and one or more helically wound fiber courses 4, 6 are combined with the same and / or different directions and also the same or different gradients independently of one another in any desired combination ,
  • the fibers may have an opposite grain, so that left-handed screw for left-handed drilling then a right-handed wound fiber in the edge layer 7 is present and vice versa the plastic tube 1 for right-handed drilling a right-handed screw with has left-handed fiber profile in the edge layer 7.
  • the geometry of the fferprofilleiter each left- or right-handed thread-compatible with various standard accessories from the left-rotary impact drilling area or from the right-rotary drilling area can be screwed.
  • the continuous screw 3 also in mortars and concrete with optimized related ribbed surface excellent composite properties.
