Definitions

  • the invention relates to an arrangement for fixing posts for protective walls on structures or foundations.
  • the object of the invention is, in the case of extremely high demands of high-speed lines to provide an arrangement for attachment of posts, through which the negative effects of misalignment of built-in elements and the strong AC voltages in the fasteners due to the highly dynamic effects on the Durability excluded or at least reduced.
  • the necessary maintenance interval of the post fixtures should be increased to 50 years or more!
  • the application of the bias is done in such a way that about 24 hours or later after the production of Pageis by grout a tightening torque is applied to the fastening nuts, which is 75% of the necessary according to the blueprint tightening torque. (Only then may the wall elements of the noise barrier be installed.)
  • Typical values of prestressing, as required on posts for noise protection walls in addition to high-speed lines, are approximately between 25 and 120 kN, usually between 60 and 90 kN, for 8.8 threaded rods.
  • the tightening torques of the fastening nuts are approximately between 100 and 550 Nm, usually between 250 and 400 Nos.
  • the negative influence of the misalignment of the mounting elements on the durability of the attachment is due to the fact that the skewed threaded bolt an eccentric load introduction arises, which acts as a bending stress on the threaded bolt and thus represents an additional burden.
  • the compensation device which according to the invention comprises a conical socket and a spherical disk, makes it possible to compensate misalignments of the threaded bolts on the installation elements and thus to initiate the load centrally, ie in the direction of the longitudinal axis of the threaded bolt. As a rule, angle deviations of up to 3 ° can be compensated.
  • angle deviations of up to 3 ° can be compensated.
  • an interaction between loading and unloading which is often accompanied by a change of sign of the stresses in the anchoring element.
  • a free length of the anchoring rod is required, in which an unrestricted pre-strain can be imposed.
  • the invention surrounded above the involvement in the concrete of the structure of the anchoring rod with a material that prevents the frictional connection between the anchoring rod and the potting material that is installed between the base plate and structural concrete. In the footplate, this is geometrically ensured by a corresponding size of the holes / holes in the plate.
  • the continuous anchoring of the concrete structure in which no force is required over an anchoring length in the building by bonding between anchoring rod and concrete - the free stretch length can be in the component.
  • the installation of a Hüllroh- Res which is filled with suitable material, an alternative to the mere encasing of the anchoring rod.
  • the cladding material must be sufficiently extensible not to hinder the change in length of the anchoring element in the course of the bias. It has been shown that certain types of bitumen are very suitable.
  • Prestressed connections require special attention with regard to corrosion protection. This results in a further requirement for the cladding material: it must ensure corrosion protection.
  • the anchoring elements are galvanized / pretreated, so that there must be no material incompatibility between the alloy and the cladding material. Also, a resistance to the surrounding material mortar and its alkaline properties is necessary. Furthermore, a high degree of diffusion-tightness is required, which also withstands the dynamic stresses (vibrations). For this purpose, especially materials are suitable, which - like bitumen - crawl though with permanent force effect, however, respond elastically with short-term force.
  • the mounting element comprises at least four anchors, which are assembled by means of cross connection bars to form a structural unit. This requires before pouring the concrete of the structure or foundation to be positioned only a mounting element on which all the necessary for the attachment of the post threaded portions are formed. Alternatively, it is also possible that several - at least four -inclusive elements, which only comprise individual anchors, are provided. Such an arrangement is to be preferred if the installation elements are to be fastened by gluing in the concrete body or anchored by complete anchoring of the concrete body.
  • the anchors have a section made of a ribbed steel - in this case the usual structural steel Bst 500S has proven to be sufficient.
  • the threaded portion for screwing the fastening nut is usually formed on the anchor and thus designed in one piece with this.
  • the threaded portion is formed by a Gewindebol- zen, which is screwed into a threaded bore of an armature formed on the sleeve portion.
  • a variant of the invention which further increases the stability of the post anchoring, provides that the threaded bolts / threaded rods do not protrude perpendicular to the base plate of the anchoring element down into the concrete, but by an angle ⁇ , which is between an angle ⁇ and ß ( ⁇ ⁇ ⁇ ß), slightly inclined outwards.
  • the angle ⁇ results from the dimensions of the base plate, the height of the personallyplattenunter spatt ceremonies and the material thereof.
  • the parallel alignment is not the ideal nominal state. Rather, the armature / threaded rods should also have an inclination to the outside when using the system ball disc / cone, so that the tensile force acts on vibration of the post parallel to the screw axis.
  • Angle ⁇ inclined to the vertical direction (Due to the thickness of the foot plate / the side, the angle moves in the region of 5 degrees, so it is not negligible.)
  • the threaded rods are then no longer as parallel to each other as before.
  • the angle is dependent on the elastic properties of the materials between the angles ⁇ and ß in the figures, due to the materials used in most cases often at ⁇ , so that then ⁇ can be chosen as a good approximation (due to manufacturing tolerances ⁇ ⁇ 30%).
  • a spacing element be arranged between the footplate and the concrete body, which is preferably located in a centroid of the footplate.
  • the space between the foot plate and concrete body around this spacer is filled with a layer of low-shrink mortar or other suitable potting compound.

Abstract

L'invention concerne un ancrage de pieux pour des parois de protection sur des chantiers de génie civil, disposant d'un système rondelle sphérique/rondelle concave pour la compensation d'éventuelles positions en biais dans le but d'une introduction quasiment centrée des charges, dans lequel les éléments d'ancrage sont précontraints de manière tout à fait déterminée et sont entourés, dans leur longueur libre précontrainte, d'un agent de préférence viscoélastique, anticorrosion. L'ancrage de pieux comprend un élément de montage qui est intégré dans le béton de l'ouvrage. En variante, un ancrage ultérieur est réalisé en ce que des trous sont réalisés dans le béton déjà réalise de l'ouvrage. Ceux-ci peuvent être traversants, l'ancrage ayant alors lieu avec une tige d'ancrage continue et un contre-vissage correspondant. Le trou peut également n'être réalisé que jusqu'à une profondeur d'ancrage nécessaire et une tige d'ancrage est alors collée dans le trou de forage.
