Definitions
- the invention relates to an injection anchor or compression body for the transmission of mechanical stresses in buildings in civil engineering, and for introduction into a bore, in slots or similar openings, with a centrally disposed filling hose and at least one surrounding the filling hose fabric stocking.
- injection or injection anchor For attachment of building parts to unsafe surfaces, for the renovation of buildings and for the protection of buildings that are at risk from damage to the mountain, injection or injection anchor are used. These are according to DIN 4125 to components in which by pressing in injection mortar around the rear part of an introduced into the ground Stahlzuggliedes a pressed body is produced, which is connected via Stahlzugglieder and anchor head with the component to be anchored or mountain part.
- injection or injection anchor are also used in tunneling for anchoring the tunnel inner shells, for grouting and for needling of the hanging wall in mining.
- injection anchors are listed, for example, in DIN 4125 and 4128. If, for example, in certain areas over defined lengths or borehole depths increased load or moment abrasions take place, then the known injection or injection anchors are not or not particularly suitable for this purpose.
- the known injection or injection anchors are factory-made, so that the borehole depths from which special voltage or load transfers are to take place during armature production must be known, but this raises significant production and storage problems, since these are custom-made. Mass production can not be carried out then.
- the invention has for its object to provide an injection or injection molding, which can be adapted to the requirements locally and compiled on the site in a simple manner, mounted and can be used immediately. This preferably relates to the anchor lengths.
- Such injection anchors can be set exactly on the site on site with regard to their length and pre-fix or fix and introduce in this state in the borehole.
- the elements of a pair are formed according to the invention the same or dissimilar, so that a large adaptation to the conditions on site and each well can be done.
- the pairs of elements are formed differently from each other, so that even with this feature a high degree of flexibility for the desired adjustment is present.
- the adaptability is further increased by the fact that the number of elements of a pair is unequal.
- the end pieces of the elements of a pair are formed as holding elements, hooks, plates, perforated plates, ring elements or limit pieces, which interact to determine the length of a pair in an advantageous manner.
- the end piece of an element has a ring closure or bores which slidably receives or receives the respective other element of the pair.
- the reinforcing wires and / or reinforcing threaded rods and / or rod and / or extensions are each formed deformed over at least part of their length and have different lengths between each other.
- Such injection anchors or compressed bodies then consist of a few conventional elements that can be easily mounted on the site and the circumstances, especially with regard to the required length can be adjusted. Both the compression body length and the adaptation to the expected Stress or load transfer can be produced in a simple manner on site, for example by selecting the number and cross sections of the reinforcing elements to be used.
- the meshes of the fabric stockings are designed such that only a small part of the filling material can escape radially, whereby this expands and the lying around the fabric stocking reinforcing wires, rods, tubes or -errirblechst Shape are urged to the outer periphery.
- the reinforcing wires and / or rods and / or tubes are advantageously arranged along the axis of the body outside of the inner tissue stocking, which are selectively connected to the fabric of the stocking, such that a positional fixation of the Beweh-elements after the filling of the anchor is guaranteed.
- the outer and / or the inner fabric stocking is stretchable, so that an adaptation to the borehole is given, which must be designed according to the loads to be removed or voltages to be displaced. This results in the same basic elements a great deal of scope for an adaptation of the injection or injection molding.
- the fabric stockings are formed at least in sections as Metallgewirk, whereby the application possibilities are considerably expanded.
- the knitted fabric is formed, for example, from very thin wires or metal threads, which have an expansion possibility up to 20% of the stocking circumference due to their loop position.
- the inner fabric stocking is advantageously slightly shorter than the reinforcing wires, rods, pipes or strakes formed so that the contents flow to the end of the inner fabric tube, there exits undisturbed and inside the outer fabric tube, which at its lower end is closed, flows back until it swells out of the borehole in the region of the filling inlet, whereby it is indicated that the filling of the injection body is successfully completed.
- the wires and / or rods are U-shaped, with their bent parts preferably being arranged at one end of the injection or compression body.
- the reinforcing elements of the injection or compression body are in its peripheral region. Further advantages of this variant are that the pull-out strength of such a wire or rod bundle is substantially improved.
- each reinforcing wire and / or rod and / or tube are at least partially deformed over at least part of their length.
- each reinforcing wire and / or rod and / or tube or a group of wires and / or rods and / or pipes at predetermined locations over a predetermined length for the voltage shift or load and / or Moment removal from defined zones has deformations. For example, if load or torque erosion in certain successive areas of different sizes, so can be selected for each area wires, tubes or rods, their strength and number according to the load or torque transfer wherein a wire or bar bundle for load transfer is assembled from a single area, while another bundle of wires, tubes or bars takes over the load or moment removal from another area.
- the wires and / or rods and / or tubes are corrugated, similar to a hairpin, and / or twisted, the deformations preferably being provided at the locations and in the areas where the individual loads or moments occur.
- steel or glass wool can be drilled.
- the injection body according to the invention also makes it possible to improve the filling process by providing an end plate connected to the reinforcing elements or an adapter on the anchor head, which can be connected to a vibrating device, such that the generated mechanical vibrations can be transmitted to the reinforcing elements.
- vibration energy can be brought into all areas of the injection anchor, so that the flowability of the filling material is improved.
- the injection body are made in considerable lengths without problems in the introduction of the contents occur. It can thus anchor lengths of the order of 50 m and more produce. This also has the advantage that such injection body can be made on site.
