Definitions

  • the invention relates to a clamping system to avoid harmful tensile and shear stresses in possibly multilayer masonry slabs, which are subject to both thermal and mechanical deformation stresses and in which the masonry is clamped by means of clamping plates to which the clamping forces of the anchors with the aid of yoke-like supports and intermediate springs or distance pieces are transmitted.
  • the task is to generate sufficient pressure prestresses 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 cracks by superimposing corresponding compressive stresses.
  • the task is thus solved according to the invention as an optimization of the elements of the overall system connected via the force flow.
  • 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 laterally separated as far as possible into 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 construction elements of the clamping system are designed to be resilient in such a way that they largely compensate for the interference.
  • the advantages of the spring elasticities provided in the clamping system are, 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 production of the desired distribution of the clamping forces over the length of the clamping plates can be done by a corresponding gradation of the thickness of the spacers or by relaxed built-in spring elements, the z. B. subsequently panned by the cross anchor or the furnace expansion or in the so-called one-step process directly by spring elements that are installed in the prestressed blocked state, and their supports are adjusted so that after Removal of the blockage results in the desired force distribution, or in the so-called two-step process, initially quantitatively precisely using 1 or more mechanical, hydraulic or pneumatic clamping elements, i.e. with correspondingly adjustable clamping tools with specified local clamping forces and then using adjusted pressure elements such as spacers or spring elements that take over the force distribution .
  • Figure 3 the three pressure elements 6 are used as spring elements.
  • Figures 4, 5 and 6 illustrate the deformations of the yoke-like support 5a and the clamping plate 7a with normal length of the cross anchor compared to the accidents with increased length of the cross anchor or reduced cross anchor force 5b and 7b. In the latter case, the thermal curvatures predominate at the ends of the deformation curves of the yoke-like support 5b and the clamping plate 7b. These are caused by the temperature gradient from the inside of the furnace to the outside and change depending on the conditions of operation and the weather.
  • the prestresses in the partition walls (9 in FIG. 1) are produced either directly by adjusting the prestressed blocked pressure element (6 in FIG. 1) between the clamping plates 7 and the yoke-like support 5 arranged in front of them and then lifting the blockade or initially by adjustable ones Tensioning 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%.
  • Gas pressure bellows 13 according to FIG. 11 d can also be coupled, for example, to the pressure regulator (PC) or a corresponding positioner (positioner), that the exhaust air consumed by the controller is used, for example, as cooling air or is taken directly from the gas pressure bellows at the top and thus serves to dissipate heat.
  • PC pressure regulator
  • positioner positioner
  • Figure 12 shows according to claims 18 and 19 spring pressure elements 6 relaxed (Fig. 12a) and biased (Fig. 12b).
  • bracketed values are intended to indicate that deviating (boundary) conditions can be decisive in these areas, e.g. B. 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.
  • the clamping system according to the invention can preferably be used in partition walls in industrial furnaces, in particular in heating walls of coking furnaces.
