Definitions
- the invention relates to a clamping system for avoiding harmful tensile and shear stresses in possibly multi-layer 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 pre-stresses in the partition walls despite changing thermal and mechanical deformations of the outer clamping system and to ensure them constantly in order to avoid tensile cracks by superimposing corresponding pressure 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 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 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 spring elements that z.
- 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 carrier 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%.
- FIGS. 11 and 12 various schematically illustrated exemplary embodiments for the pressure elements 6 can be seen in relation to claims 14 to 19. 11d can also be coupled to the pressure regulator (PC) or a corresponding positioner (positioner), for example, so that the exhaust air consumed by the regulator z. B. is used as cooling air or is taken directly from the top of the gas bellows 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).
- FIGS. 13 to 16 schematically show, for example, the design and arrangement of the pressure elements 6 as spiral springs according to claims 1, 20, 21, 22 and 24.
- Figure 13 schematically illustrates a possibility for generating the bell-shaped course of the pressing forces according to claim 1 with the same spiral springs z.
- FIG. 14 indicates how the force redistributions in the event of changes in the thermal curvatures of the yoke-like carrier 5 are largely mitigated by the softer springs 6 in the middle when the line load on the clamping plate 7 is approximately constant.
- the clamping plate 7 is expediently designed to be relatively rigid.
- FIG. 16 shows a combination of FIGS. 13 to 15, for example, which fulfills the requirements for a 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. 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 with partition walls in industrial furnaces, in particular with heating walls of coking furnaces.
