Definitions

  • the invention relates to a clamping system for avoiding harmful tensile and shear stresses in possibly multi-layer masonry panes, for example partitions in industrial furnaces, in particular heating walls of coking ovens, which are subject to both thermal and mechanical deformation stresses and in which the masonry is clamped by clamping plates to which the clamping forces are applied the anchor can be transferred with the help of yoke-like supports and intermediate springs or spacers.
  • the task is to generate sufficient pressure pre-stresses in the partition walls and to ensure them constantly in spite of changing thermal and mechanical deformations of the outer clamping system in order to avoid tensile stress cracks by superimposing corresponding compressive stresses.
  • the task position is therefore according to the invention as an optimization tion of the elements of the overall system connected via the flow of force.
  • the wall warps the most when it is loaded from the side halfway up.
  • the clamping pressure forces of the wall are chosen to be the highest in the center and their contact surfaces are as far apart as possible in the two outer edge zones , the resultants of the two marginal forces acting parallel to or in the direction of the vertical wall center plane.
  • the individual structural elements of the clamping system are designed to be resilient in such a way that they largely compensate for the interference.
  • the advantage of the spring elasticities provided in the clamping system is, on the one hand, the small displacements in the force distributions and, on the other hand, the lighter and cheaper design, in particular with larger partition wall dimensions.
  • the desired distribution of the clamping forces over the length of the clamping plates can be produced by appropriately grading the thickness of the spacers or thanks to the spring elements installed in a relaxed manner, which can be subsequently tensioned by the cross anchors or the furnace expansion or in the so-called one-step process directly through spring elements, which are installed in the pre-tensioned blocked state and whose supports are adjusted so that the desired force distribution results after the blockade is released, or in the so-called two-step process, first of all precisely with one or more mechanical, hydraulic or pneumatic clamping elements, ie with appropriately adjustable clamping tools with specified local clamping forces and then with adjusted pressure elements such as spacers or spring elements, which take over the force distribution.
  • the prestresses in the partition walls (9 in FIG. 1) are produced either directly by adjusting prestressed blocked pressure elements (6 in FIG. 1) between the clamping plates 7 and the yoke-like support 5 arranged in front of them and then. Unblock or first by means of adjustable clamping elements between the clamping plate 7 and the yoke-like carrier 5, which is pretensioned, and then by adjusting the pressure elements 6.
  • the prestresses in the partition walls are to be constantly maintained by the spring properties of the transverse anchor system (1 and 3 in FIG. 1), the yoke-like supports 5, the clamping plates 7 and 8 and the pressure elements 6.
  • the load changes in the usual clamping forces can be kept within the tolerance limits according to claim 1.
  • the springs at both ends of the cross anchor can be combined in a one-sided spring with half the spring constant if the changes in force are transmitted from one side to the other.
  • the factor q is a maximum of 20%.
  • Fig. 8 the resulting force vectors of the clamping forces in a two-part clamping plate 7a and 7b and the pressure surfaces 10 on the masonry are shown in accordance with claim 1.
  • the filling and formation of the joint 8 or 10 between the clamping plate 7 and masonry 9 is described in claims 32 to 34.
  • Gas bellows 13 according to Fig. 11d can for example also be coupled to the pressure regulator (PC) or a corresponding positioner (positioner) such that the exhaust air consumed by the regulator e.g. is used as cooling air or is taken directly from the gas pressure bellows and is used for heat dissipation.
  • PC pressure regulator
  • positioner positioner
  • Fig. 12 shows according to claims 2o and 21 spring pressure elements 6 relaxed (Fig. 12a) and biased (Fig. 12 b).
  • 13 to 16 schematically show, for example, the design and arrangement of the pressure elements 6 as spiral springs according to claims 1, 22, 23, 24 and 26.
  • Fig. 13 schematically illustrates a possibility for generating the bell-shaped course of the pressing forces according to claim 1 with similar spiral springs e.g. according to claim 22 with a relatively flexible clamping plate 7.
  • Fig. 14 indicates, in contrast, how with approximately constant line load on the clamping plate 7, the force redistribution when changes in the thermal curvatures of the yoke-like carrier 5 are largely mitigated by the softer springs 6 in the middle.
  • the clamping plate 7 is expediently designed to be relatively rigid.
  • FIGS. 13 to 15 shows, for example, a combination of FIGS. 13 to 15, which meets the requirements for bell-shaped course of the pressing forces and for alleviating the effects of the thermal curvatures with a relatively thin clamping plate.
  • bracketed values are intended to indicate that different (boundary) conditions can be decisive in these areas, such as manufacturability or additional functions of the clamping system.
  • the yoke-like carrier or the clamping plate is composed of several parts, the area moment of inertia combined according to the rules of statics is decisive.
  • the gradations of the moments of inertia can be generated, for example, by recesses or corresponding screw connections.
