Description

[0001] The invention relates to a bearing for arrangement between two load-bearing components, in particular of a building, wherein the bearing is delimited by two substantially parallel load sides for contact with the components and wherein the bearing has at least one polyurethane layer and at least one fiber-reinforced reinforcement layer, wherein the at least one polyurethane layer and the at least one reinforcement layer are glued to one another.

[0002] Furthermore, the invention relates to a method for producing such a bearing.

[0003] Bearings of this type are used for the elastic support of structures to compensate for structural movements or to isolate one part of a structure from vibrations from another part of the structure or from vibrations from the subsurface. The bearings are in direct contact with the structure, with force transfer between the bearing and the structure occurring via pressure and friction, and / or with the bearing being used to transfer loads from the structure in the vertical and / or horizontal directions.

[0004] Such bearings are generally already known, although they are usually designed for a specific application or a few specific applications. For example, EP 3 555 368 B1 shows a reinforced elastomer bearing made of alternating polyurethane and reinforcement layers. This bearing is specifically designed to minimize unwanted creep of the bearing due to long-term, very high loads. However, it is not designed to effectively protect buildings and building occupants from higher-frequency vibrations.

[0005] Higher-frequency vibrations, which typically have frequencies above 10 Hz (perceptible), and especially above 30 Hz (audible), are a particular problem in cities, as they are induced by traffic routes such as subway or railway lines and roads, as well as by industrial facilities. These types of vibrations not only impair the usability and load-bearing capacity of buildings, but are also extremely unpleasant and disruptive for building occupants and therefore require effective vibration isolation.

[0006] The object of the present invention is therefore to provide a bearing which is improved compared to the prior art and which efficiently protects both the building and building users and systems or devices within the building from higher-frequency vibrations and effectively meets the associated, particularly high requirements for the insulation effect.

[0007] This task is solved by a bearing as mentioned above, in which the polyurethane layer has a static shear modulus of 4.0-5.4 N / mm 2< , preferably of 4.5-4.8 N / mm 2< .

[0008] The static shear modulus G can be measured or determined according to ISO 1827:2022-08, Method A, at room temperature of 23+ / -3°C without artificial aging.

[0009] The major advantage of the bearing according to the invention is that, due to its specially selected shear modulus, it is capable of effectively isolating buildings from high-frequency vibrations. On the one hand, this effectively protects building structures, as relative movements of the components in particular are significantly dampened, which in turn can significantly reduce or even prevent structural damage such as cracking, spalling, or the like. On the other hand, due to the insulating effect of the bearings, building occupants are neither affected nor disturbed by tangible or audible vibrations.

[0010] In addition, sensitive equipment and systems can be operated in the insulated building or the insulated part of the building, which would otherwise be disturbed or affected by vibrations from the environment or from the non-insulated part of the building.

[0011] The bearing according to the invention is of course also capable of safely and permanently transferring applied loads, such as dead loads, earthquake loads, snow loads and / or wind loads, both in the vertical and horizontal directions.

[0012] Furthermore, the bearing is advantageously capable of compensating for any deformations of the supported structure, thus reducing the loads on the structure, especially local ones, and / or avoiding loads from constraints. In this case, too, structural damage can be significantly reduced or even prevented.

[0013] The bearing is designed to be arranged between two load-bearing components of a structure to provide elastic support for the structure. It can be used effectively even in very limited space conditions, especially within a building structure, because its shear modulus allows it to be dimensioned relatively small.

[0014] The warehouse is designed specifically for the storage of buildings, parts of buildings and / or large foundations, but can also be used for the storage of bridges or other structures.

[0015] The bearing has essentially parallel load sides, particularly in an unloaded state. However, this parallelism may not necessarily be exact due to possible manufacturing tolerances. Furthermore, the load sides may not be parallel to each other in a loaded state, particularly due to asymmetrical pressure on the bearing.

[0016] The bearing is preferably designed to be applied to the components on its load sides under direct contact, wherein the force transmission between the components and the bearing preferably takes place via friction and / or pressure.

[0017] In principle, however, the bearing can also be designed to be attached to at least one of the two components, in particular to secure the position of the bearing on the components, for example, to prevent unintentional slippage on the components of the bearing. For this purpose, the bearing can have at least one opening for receiving a connecting, position-locking, or fastening means.

[0018] Further advantageous embodiments of the bearing are defined in the dependent claims.

[0019] It is particularly preferred that the bearing comprises multiple polyurethane layers and / or multiple reinforcement layers, wherein a reinforcement layer is arranged between two polyurethane layers and / or wherein a polyurethane layer is arranged between two reinforcement layers.

[0025] The static compressive stiffness of the bearing can be derived from the compressive stress sigma_10 of the polyurethane layer.

[0026] It is particularly preferred that the bearing has a dynamic stiffness C_dyn at an average compression of 10%, in particular of the bearing and / or polyurethane layer height, in an unloaded state and a sinusoidal, dynamic deformation with an amplitude of 0.1 mm and a frequency of 10 Hz, which by means of C_dyn = k*A*sigma_10FF can be defined and determined.

[0028] Since k is preferably in the range of 40-1830 1 / m, particularly preferably in the range of 140-570 1 / m, C_dyn is also preferably in a range.

[0029] The area A of the bearing and / or the polyurethane layer corresponds in particular to the cross-sectional area over which a load is transferred normally to the load sides as a normal force.

[0030] Preferably, the area A corresponds to a bearing base area of ​​the bearing and / or an area of ​​at least one of the load sides of the bearing.

[0034] A measurable dynamic stiffness C_dyn_mess of the bearing, which is preferably in the range of C_dyn, can be determined by means of C_dyn_mess = F_max − F_min / v_max − v_min where F_max is the maximum load or force at maximum deformation v_max and F_min is the minimum load at minimum deformation v_min. These values ​​correspond to the extreme values ​​of a hysteresis loop of a force-deformation curve or Fv curve measured in the test. C_dyn_mess is the gradient of a straight line connecting the extreme values, i.e., the maximum values ​​F_max and v_max and / or the minimum values ​​F_min and v_min, of the hysteresis loop.

[0035] The determination of the hysteresis loop or the force-deformation relationship, for example by means of measurements using a servo-hydraulic testing machine, is preferably carried out as follows: Applying a deformation to the bearing under a compressive load to 90% of its bearing height in the unloaded state at a constant deformation rate of 10% compression per 10 seconds; measuring a mean load immediately after applying the deformation; loading the bearing with this measured mean load during the following sequence; measuring the dynamic stiffness C_dyn_mess of the bearing, whereby a sinusoidal deformation with an amplitude of 0.1 mm and a frequency of 10 Hz is applied as a vibration load superimposed on the measured mean load; recording the force-deformation or Fv relationship as a result of this vibration load, in particular if it is of longer duration, as a hysteresis loop; determining the extreme values, i.e. the maximum values ​​F_max and v_max and / or the minimum values ​​F_min and v_min, of the force F and deformation v of the recorded hysteresis loop.
