  • the object of the present invention is to provide a compact and robust roller support and, to this end, the invention provides a roller support according to claim 1.
  • the roller support according to the invention can be used for various applications, but is particularly suitable for use in the building industry for supporting sliding formwork.
  • the present invention also relates to the combination of a roller support of this nature and sliding formwork for pouring concrete.

  • Fig. 3 shows a cross section on line III-III in Fig. 2, with the roller having slid to the other side.
  • Figures 1, 2 and 3 show a hydraulically adjustable roller support 1, which is particularly suitable for use as vertically adjustable support for sliding formwork.
  • sliding formwork is used for pouring concrete.
  • sliding formwork of this nature comprises two wall formwork panels, which are spanned at their top sides by a floor formwork panel which forms the underside of the next floor of the building.
  • a formwork element of this nature which is substantially in the form of an inverted U, usually covers only part of the storey of the building which is to be constructed and is therefore repeatedly displaced a certain distance in the horizontal direction in order to allow another part of the storey to be poured.
  • the metal bearing rail 2 which is present on the underside of a limb of the U and in this example is composed of a box section 3 and a strip 4 lying beneath it, of sliding formwork of this nature can be seen.
  • the rail 2 is approximately in the form of an inverted T.
  • Figures 1 and 3 also show part of the concrete floor on which the roller support is positioned.
  • the roller support 1 comprises a frame 5, which defines a base surface 6, which is to be placed on the floor, of the roller support.
  • the frame 5 comprises a robust, elongate metal baseplate 7, which forms the base surface 6, and two raised cheeks 8, 9.
  • the cheek 8 has been left out for the sake of clarity.
  • the roller support 1 furthermore comprises a pair of rotatable rollers 10, 11 with axes of rotation 12, 13 which are parallel to and at a distance from one another and are substantially parallel to the base surface 6.
  • Each roller 10, 11 of the pair of rollers is accommodated in an associated tilting yoke 14, 15.
  • Each tilting yoke has a roller-bearing axle 16, 17 for the roller 14, 15.
  • the ends of each roller-bearing axle 16, 17 project into a tilting-yoke arm 20, 21 and 22, 23.
  • These tilting-yoke arms of each tilting yoke are fixedly connected, in this case via welded joints, by a tilting axle 24, 25, which is tiltably mounted in the frame 5.
  • the tilting-yoke axles 24, 25 are in this case robust steel axles with journals which project outside the tilting-yoke arms and each fit into a bearing recess in the cheeks of the frame 5.
  • each tilting yoke can be put into and removed from the bearing recesses transversely with respect to the direction of the tilting axle.
  • each tilting yoke 14, 15 is attached to the frame 5 in such a manner that it can tilt about an associated tilting axle 24, 25, which lies at a distance from and substantially parallel to the rotation axle 16, 17 of the associated roller 10, 11.
  • Each tilting yoke 14, 15 furthermore comprises an actuator-attachment element 28, 29 which, on that side of the tilting axle 24, 25 which is remote from the roller-bearing axle 16, 17, is arranged between the tilting-yoke arms 20, 21, 22, 23 and which is in the form of an axle which is parallel to the tilting axle.
  • the tilting yokes 14, 15 are in this case arranged in such a way that they face towards one another on the sides of their actuator-attachment elements 28, 29.
  • Figures 1 and 2 also show a hydraulic act -.ator 30, which in this case is designed as a double-acting linear hydraulic cylinder and is located between the cheeks 8, 9 of the frame 5.
  • the cylinder 30 has a cylinder housing 31, which at one end has an attachment point 32 which is pivotably attached to the axle 29 of the tilting yoke 15.
  • the cylinder 30 has a piston rod 33 which can be extended and retracted and, at its free end, is provided with an attachment point 34, by means of which the piston rod 33 is pivotably attached to the axle 28. It will be clear that the cylinder 30 is shown in its fully retracted position.
  • the cylinder 30 has two connectors 35, 36 for hydraulic lines leading to the working chambers of the cylinder 30. These connectors 35, 36 are in this case designed as quick-connection couplings. In the cheek 8, there are holes through which the connectors 35, 36 fit.
  • the roller support is combined with a first hand pump connected to the connector 36 and a second hand pump connected to the connector 35.
  • the cylinder 30 is free from the frame 5 and is attached only to the tilting yokes 14, 15.
  • the hydraulic actuator 30 enables the height of the bearing rollers 10, 11 to be set accurately.
  • bolts 39, 40 are used in order to allow the assembly to be dismantled easily.
  • the roller-bearing axles 16, 17 fit into associated holes in the tilting-yoke arms and small locking plates 42, which are releasably fixed by means of bolts, hold the roller-bearing axles 16, 17 in place.
  • the roller-bearing axles 16, 17 are longer than the rollers, and the rollers 10, 11 can each slide to and fro along the associated roller-bearing axles 16, 17. Furthermore, for each roller 10, 11 there is a U-shaped guide member 44, 45, having a limb at each end of the roller, through which the roller-bearing axle fits, and having a web running parallel to the circumference of the roller. Each limb of a guide member 44, 45 furthermore forms a positioning projection 46, 47 which projects above the roller 10, 11 and extends as far as above the strip 4 of the bearing rail 2. At the top end, each positioning projection 46, 47 engages over that edge of the strip 4 which projects outwards.
  • the guide members 44, 45 in combination with the ability of the rollers 10, 11 to slide along their axles 16, 17 enables the bearing rail 2 to be displaced, within a defined range, transversely with respect to the direction in which it rolls along the rollers 10, 11. This prevents the bearing rail 2 from running off the rollers 10, 11 when the sliding formwork is displaced and also facilitates the positioning of the roller support 1.

Abstract

L'invention concerne un support de galet à réglage hydraulique, s'utilisant notamment pour soutenir un coffrage destiné à couler du béton. Le support de l'invention comprend un cadre, qui définit une surface de base dudit support et qui se place sur le sol, une paire de galets tournants dotés d'axes de rotation parallèles, espacés l'un de l'autre et sensiblement parallèles à la surface de base, ainsi qu'un actionneur hydraulique pourvu d'un premier et d'un second point d'attache. Chaque galet de la paire de galets est logé dans un étrier pivotant associé, chaque étrier étant fixé au cadre de manière à pouvoir pivoter autour d'un pivot associé, espacé de l'axe de rotation du galet correspondant et sensiblement parallèle à celui-ci. L'actionneur hydraulique est relié à un étrier pivotant au moyen de ses points d'attache, de telle manière que lorsque l'actionneur est sollicité, lesdits étriers pivotent dans des directions opposées autour de leurs pivots, ce qui modifie la hauteur des galets par rapport à la surface de base.
