Definitions

  • the invention relates to a formwork arrangement for the cantilever construction of bridges.
  • the storage of all movable elements usually takes place by means of rollers.
  • the formwork arrangement can be advanced to establish the reinforcements for the next section.
  • the rails or beams on which the formwork arrangement is mounted can be extended to the last created building section.
  • DE 28 48 536 A1 relates to a similar arrangement in which sliding bearings can be provided. Further formwork arrangements from this area are evident from EP 0 004 251 A1, DE 26 60 087 B1 and US Pat. No. 3,989,218.
  • the invention has for its object to provide a formwork arrangement for the cantilever construction of bridges with an extended application and / or improved security.
  • this has at least one largely horizontal slide bearing, which has at least one bearing part made of plastic, in particular polyethylene.
  • plain bearings offers the following advantages over the previously used roller bearings.
  • roller bearings even at low bridge radii there is a risk that the rollers may be made of the rails or rails provided for them !
  • the considerable weight of such formwork arrangements which may be heavy, for example, several tons, there is a considerable amount of space for them to be stored on flanges or the like
  • roller bearings are on structures with gradients problematic because for advancing the formwork arrangement usually oscillating cylinders are provided, which are supported in a first operating state on a support or a rail, which is attached to an already created building section, and advance the formwork arrangement. In a second operating state, the formwork arrangement remains in place and the cylinders are retracted so that the supports are retightened. In this situation, the usually tons-heavy formwork arrangement is unsecured and can move forward on a gradient due to the roller bearings described, which represents a significant security risk.
  • the plastic bearing part according to the invention significantly reduces the risk of the bearing moving out of its rail or from the support provided for storage. Furthermore, a plastic bearing part has proven to be advantageous in that it can be designed to be self-locking up to a certain gradient. Accordingly, even with structures with gradient, the formwork arrangement safely stay in place and the support, as described, be tightened. In other words, the bearing forces are calculable and can be taken into account for a defined behavior of the entire formwork arrangement, even during the second operating state described above. Finally, the plastic plain bearing according to the invention offers a comparison with roller bearings improved, namely area force application.
  • the plastic bearing part is currently preferred to provide this on a movable part of the formwork arrangement.
  • the immovable part of the formwork arrangement for example, one or more Rails or carrier may have a considerable longitudinal extent to ensure a certain range of motion for the formwork arrangement. If you were to provide it plastic bearing parts, they would also extend over a considerable area. In that regard, for reasons of efficiency, it is currently preferred to provide the plastic bearing parts on the comparatively short moving part of the formwork arrangement or only on individual sections thereof.
  • a bearing part made of metal, preferably steel proved to be favorable as a further bearing part that cooperates with the plastic bearing part.
  • the sliding bearing be self-locking up to a gradient of about 5%, preferably about 6%, and more preferably up to 10%.
  • a wide range of applications can be covered with a particularly secure approach.
  • the attachment of the plastic bearing part can be particularly easily and efficiently done in a magnetic manner.
  • the plastic bearing part can be provided in an advantageous manner as part of a sliding bearing between any movable components or portions of a chamfer arrangement for cantilever construction, in particular of bridges.
  • the first attempts were particularly good experiences made when such a plain bearing between an inner shell carriage and / or a side mold on the one hand and a fixed portion of the formwork arrangement on the other hand was provided.
  • Fig. 1 is a perspective view of a formwork arrangement according to the invention
  • FIG. 2 is a perspective view of a hollow section beam in the formwork arrangement of FIG. 1;
  • Fig. 3 is a bottom perspective view of a slide bearing in the formwork arrangement of Fig. 1;
  • FIG. 4 shows a perspective, partially cutaway view of a detail from FIG. 1.
  • the shuttering arrangement 10 which in the cantilevered direction can have an extension of a few meters, for example of five meters, is supported on an already created section 30 of a bridge.
  • the already created bridge section 30 can cantilever freely, and the formwork arrangement 10 can be provided to create a further, in turn cantilevered section.
  • To support the formwork arrangement 10 are in the case already shown four bridge section 30 Support 32 mounted, which essentially serve the storage and support of the formwork arrangement 10.
  • the carriers 32 essentially act as rails on which the shuttering arrangement 10, as described in more detail below, is displaceably mounted.
  • Fig. 1 a state is shown in which the formwork assembly 10, of which any formwork is not shown, has been advanced out of the last created section and is located in the situation shown immediately before the last created section.
  • the support of the formwork arrangement 10 on the supports 32 in the case shown by sliding bearings 34, which cooperate substantially with the upper surfaces of the support 32.
  • the forward movement is accomplished in the case shown by two hydraulic cylinders 36 which oscillate and alternately, supporting themselves on supports 38, advance the formwork assembly 10 or, while the formwork assembly 10 remains stationary, the supports 38 tighten.
  • abutments 40 are provided, which can engage, for example, protruding flanges of the supports 32 in order to support the weight of the overhanging formwork arrangement.
  • anchor rods may be provided for this purpose.
  • the formwork arrangement comprises an upper support arrangement 12, which consists of transverse 20 and longitudinal members 42. About a plurality of rods 16 is suspended from the upper support assembly 12, a lower support assembly 14, which also has transverse 20 and longitudinal members 42. Standardized stages may be attached to the upper 12 and / or lower carrier assembly 14, inter alia because of the possibilities for attaching standard components described below.
  • all cross members 20 are designed as a hollow profile carrier, as explained in more detail below with reference to FIG. 2.
  • Fig. 1 it can be seen in addition that between the carriers 20, in particular in the case of the upper carrier assembly 12 by additional, for example, diagonally oriented struts 44 stabilization of the carrier assembly can be carried out.
  • diagonally downwardly extending supports 46 may be provided to form the upper formwork assembly 12 with truss-like sections. It also follows that the upper support assembly, substantially in the form of the cross member 20, in the vertical direction from the surface of the bridge portion 30 is spaced so that the space located under the upper support assembly advantageously for the required work, such as the introduction of Reinforcements, is kept free. The space available for this purpose is further increased by the fact that the mentioned diagonal struts 44 are arranged in comparatively outer regions, so that the intermediate inner region can be used in a favorable manner for the delivery of reinforcement and the like.
  • the suspension of the lower support assembly 14 is carried out in the example shown by a plurality of rods 16, in which the lower support assembly 14 is mounted in a special manner, which will be described in more detail below.
