Definitions
- the invention relates to a height-adjustable rubber pot bearing with an elastomer plate for transferring and lifting or lowering heavy loads, particularly in bridge construction, in which a locally displacing the amount of pressure fluid from the elastomer can be pressed in between the bottom of the pot and the elastomer plate.
- Rubber cup bearings of this type are known, for example from "Bautechnik” 7/1984, page 227, Figure 13.
- the task now is to seal the peripheral edge region of the elastomer plate against the inner wall of the bearing cup in order to press out the pressed-in parts To prevent hydraulic fluid.
- the stated object is achieved in that it has an elastomer plate at a short distance from the inner wall of the pot and parallel to it, narrow, open at the bottom, up to 3/4 of its thickness deep slot and in the slot a circular-cylindrical insert is used, which consists of two strips that leave a small space between each other and that are connected to one another and integrally connected at their upper edges their edges are angled at right angles to edge strips pointing in opposite directions and running parallel to the bottom of the pot.
- This embodiment creates an annular cavity open at the bottom and enclosed by the two strips, in which the pressure fluid supplied from below can enter and the insert can spread apart. This increases the pressure of the sealing lips on the inner wall of the pot and improves the sealing effect.
- the two strips can be provided with beads running perpendicular to the angled edge strips, whereby these beads can be directed inwards from both sides of the strips and touch one another, or they can also be directed outwards from the space between the strips .
- these beads can be such that they only extend to a certain distance from the interconnected upper edges of the two strips, so that an upper edge area remains free of beads, thereby reducing the rigidity of the upper edge area and this part can perform a joint function to spread the two strips.
- This joint function is further improved if the two strips are connected at their upper edges end part has a tubular, circular cross-section.
- the design can also be such that the part connecting the two strips at their upper edges has a tubular, rectangular cross section.
- the insert can either consist of sheet steel or of a plastic. It can furthermore be advantageous if the angled lower edge strips running at right angles to the strips have incisions at regular intervals. By means of these incisions it is avoided that when the originally flat insert is deformed into a circular cylindrical structure, upsetting or excessive expansion stresses occur. It can furthermore be expedient if the peripheral surface of the elastomer plate is designed before being pressed into the pot in such a way that it tapers conically upwards.
- the circular-cylindrical insert can consist of a plurality of separate individual sections, wherein the individual sections furthermore have a plug-like extension on one side and can be used to overlap astride each other.
- the insert inserted from the individual sections can slightly change its circumferential length or its diameter when the elastomer plate is pressed into the bearing pot.
- the circular-cylindrical insert consists of a polygonal line in straight individual elements, the individual elements being slightly bent in the region of the expansion around the vertical axis in the case of small diameters of the elastomer plate.
- elastomer plate with 1 the pot side wall with 2 and the bottom of the pot with .3 is designated.
- the bearing cap 4 is placed on the elastomer plate 1. 5 with the lid edge seal is referred to, which is inserted into the elastomer plate 1.
- the pressure fluid is injected through the feed line 6, so that it fills the space between the lower surface of the elastomer plate 1 and the surface (8; of the pot base 3), resulting in the space 7.
- the pressure fluid also penetrates into the cavities 22 of the insert from below and tries to spread them apart, so that the pressure of the sealing lip against the inner wall 10 of the pot side wall 2 is increased.
- the open cavities 22 of the insert can be seen from FIG.
- the side view according to FIG. 3 of the insert shows that the beads 26 only make up about 2/3 to 3/4 of the total height of the insert, so that a strip 27 remains free of beads.
- the inwardly directed beads 26 touch one another without being connected to one another.
- the upper area 27, which is free of beads, practically represents a joint, so that the sides acting as expansion legs are parts the strips of material can spread apart.
- this joint function is further improved in that this upper region is designed to be circular.
- FIG. 8 A further advantageous embodiment of the elastomer plate 1 is shown in FIG. 8. Due to the conical tapering outer surface of the elastomer plate before it is pressed into the pot, the contact pressure of the sealing lip can be increased.
- FIG. 8a shows the elastomer plate 1 before being inserted into the bearing pot, of which the inner wall 10 of the pot is indicated by dash-dotted lines.
- Insert E (see FIG. 1) consisting of strips 21 is inserted into slot 13, by means of which the gap is kept open in a radial width, which is denoted by 12.
- the bottom of the pot is indicated by dash-dotted lines at 8.
- the edge strips 25 rest on the pot bottom 8 and on the underside B of the elastomer plate 1.
