Definitions

  • the present invention relates to a method for pouring sleepers, provided with projecting reinforcing bars, to form a ballast-free slab, comprising the provision of a base, fitting said sleepers thereover this, providing longitudinal formworks, located opposite one another, and spaced transverse formworks, to enclose a series of sleepers, pouring concrete and removing said formworks.
  • Ballast is not used, especially in the case of tracks which are used for vehicles moving at high speed, but a number of sleepers are cast into a slab.
  • a slab of this type preferably lies freely on the base and has a limited length so as to be able to absorb dilatation.
  • a structure of this type is produced after provision of the base, such as a concrete structure which bears the rails plus sleepers including the ballast-free slab. It is important to be able to produce such a structure relatively quickly. In other words, the aim is every day to provide tens and preferably hundreds of meters of rails/sleepers with the ballast-free slabs concerned. It is therefore important that the formwork used for this is easy to fit and to remove. This applies in particular to the transverse formwork to be fitted at regular intervals. Furthermore, it is desirable that the formwork can be reused. Such formwork should also be easy to adapt to local conditions, such as the presence of a difference in level between the left and the right rail on a bend, inclines and other structures deviating from a straight line.
  • transverse formworks comprises arranging a transverse formwork section from each end of said sleepers in the longitudinal direction of said sleepers and placing said transverse formwork sections, which are fitted from the opposite side of said sleepe ⁇ s, against one another.
  • transverse formwork is built on to transverse formwork sections, which transverse formwork sections can be moved below the rails (between two adjacent sleepers).
  • transverse formwork sections are specified below as end transverse formwork sections.
  • the transverse formwork sections are tensioned against one another, the external pressure being applied by the longitudinal formwork sections. That is to say, longitudinal formworks located opposite one another are pressed towards one another while the transverse formwork sections are accommodated therebetween.
  • Such application of tension can be realised by fitting a strip, extending over the entire transverse direction, to the base level, said strip being provided at one or both ends with tensioning elements which act on the longitudinal formworks or a profile acting on the longitudinal formworks.
  • coupling rods at a slightly higher level than the base.
  • Such coupling rods make it possible to place the transverse formwork sections against one another at the top, thereby preventing concrete mortar being moved along them.
  • Such coupling rods are designed such that they can be moved underneath the rails and can be hooked from one side underneath the rails into a transverse formwork section which is already present, whereupon a tension can be applied.
  • Such a structure is once again easy to take apart and can in a particularly appropriate manner be made of steel, which means the structure concerned can be used many times.
  • the longitudinal formwork preferably consists of longitudinal elements which can be coupled to one another and form a continuous longitudinal formwork.
  • the invention also relates to the above-described formwork used in the method.
  • the invention will be explained below in more detail with reference to an illustrative embodiment depicted in the drawings. Therein:
  • Fig. 1 shows diagrammatically in perspective the placing of rails with sleepers on a base
  • Fig. 2 shows very diagrammatically a formwork fitted round the structure of Fig. 1 ;
  • Fig. 3 shows a section of the formwork according to Fig. 2;
  • Fig. 4 shows the longitudinal formwork;
  • Fig. 5 shows in cross-section a detail of the transverse formwork with a poured slab;
  • Fig. 6 shows in end view a detail of the transverse formwork;
  • Fig. 7 shows diagrammatically the removal of the transverse formwork;
  • a base on to which a ballast-free slab, in which the sleepers of a rail structure are accommodated, is to be poured is indicated by 1.
  • This base 1 can be any adjustable base, such as a settlement-free slab.
  • the sleepers 2 are mounted in advance on comparatively short rails 6. These rails may have a length of 14 meters, for example. Reinforcing bars 3 extend from the sleepers 2. There are hoisting jacks 5, with which the position of the rails 6 can be accurately set. Further longitudinal reinforcement or transverse reinforcement is indicated by 4.
  • the idea is to anchor the sleepers 2 in a slab to be poured, in which the reinforcement 4 is also accommodated.
  • Each longitudinal formwork consists of a wall section 9 and a beam 10.
  • This profile 10 can also serve as a runway for a concreting device or other processing device.
  • the longitudinal formworks can in principle be designed as continuous and for this purpose the appropriate longitudinal formwork sections are provided near the ends with coupling flanges, through which bolts or similar can be inserted (Fig. 4).
  • each transverse formwork consists of a central transverse formwork section 12 and end transverse formwork sections 13 abutting thereto (see Figs 2 and 5). It should be understood that it is possible to manage with only end transverse formwork sections 13.
  • Each transverse formwork section consists of two walls spaced apart. An example is shown in Fig. 6, the wall sections spaced apart being indicated by 24, between which on the one hand a groove 25 is limited and on the other hand on the underside a cavity 31. Transverse ribs and other reinforcements are of course present.
  • a tensioning strip 15 can be fitted (Fig. 3).
  • the tensioning strip 15 is provided near each end with a sliding piece 17 which can be fixed on to the tensioning strip 15 with a clamping bolt 18. In practice the tensioning strip 15 will be placed first and its position can possibly be fixed in the base 1 by bolts 29 or other means.
  • the transverse formworks 12 and 13 are placed on top of these. After this the longitudinal formworks 7 and 9 are placed over the tensioning strip 15. Subsequently, with bolt 19 of sliding piece 17 a pressure force can be exerted on the beam 10 of the longitudinal formwork concerned. If a pressure force is applied from opposite sides, the longitudinal formworks 7 and 8 will be moved towards one another while the transverse formwork sections 12, 13 are accommodated between them by clamping.
  • a clamping arm 20 acts on the top of the transverse formwork. This has an end flange 21.
  • the dimension of the end flange is greater than the dimension of groove 25 and the dimension of arm 20 is smaller than that of the groove.
  • the clamping arm 20 can be fitted hooking behind such a groove, wherein central formwork section 12 is indicated by flange 21.
  • the central transverse formwork section 12 is dimensioned such that it can be placed in between the rails 6 in the desired position above the tensioning strip 15 (Fig. 1). Both end transverse formwork sections can be fitted laterally from below, which means no conflict arises with the rails 6. The same applies to the removal of the transverse formwork after the concrete has been poured. This is shown diagrammatically in Fig. 7.
  • Arrow 26 indicates the removal of the central transverse formwork section 12 and removal of the end transverse formwork sections is shown with the aid of arrows 27 and 28.
  • the clamping arm is hooked in laterally underneath the rails 6 with the flange 21 acting on the central transverse formwork section 12.
  • transverse formwork With the structure shown here it is possible to fit a transverse formwork at any place desired and to remove it in a simple manner after the concrete has been poured and hardened.
  • the method can be used both with rails placed flat and rails placed at an incline, as shown in Fig. 5, where the end result is shown after removal of the formwork.
  • the thus obtained slab is indicated by 30.
  • transverse formwork according to the invention it is possible to bridge differences in height between the two rails of approximately 180 mm and possibly more, without problems arising during fitting and/or removal of the transverse formwork sections. It is not necessary in this case to remove the rails from the sleepers.
