A casting mould arrangement for the embedding of pipes, in which the individual pipes are assumed to be placed substantially at a predetermined distance from one another and which includes at least two base parts and at least one intermediate part. These parts are provided with recesses intended to hold the pipes securely and to fix the pipes in position, sockets which have a holder arm and are arranged at each end of the base part in order to securely hold the mould panels which are located on the sides of the casting mould and which delimit the casting mould laterally, and holes for receiving reinforcement bars. The holes include pockets in which reinforcement bars are intended to be placed and retained substantially at a predetermined distance from the bottom top and side covering of the casting mould. A base part is included in the arrangement.

The is a continuation of PCT International Application No. PCT/IB94/00120, filed Jun. 16, 1994, published as WO95/34728, Dec. 21, 1995 designating the U.S.
The present invention relates to a casting mould arrangement for the embedding of pipes, in which the individual pipes are assumed to be placed essentially at a predetermined distance from one another and which comprises at least two base parts and at least one intermediate part, which parts are provided with recesses intended to hold the pipes securely and to fix the pipes in position, sockets which have a holder arm and are arranged at each end of the base part in order to hold securely mould panels which are located on the sides of the casting mould and which delimit the casting mould laterally, and means for receiving reinforcement bars. The invention also relates to the base part included in the arrangement.
An object of the present invention is to produce an arrangement and a base part included therein of the type mentioned in the preceding background section, in which, by eliminating the disadvantages, described above, of the known arrangements, an arrangement and a base part included therein are produced in which the precise mutual positioning of the pipes and of the reinforcement bars in predetermined positions in the casting mould is facilitated, and, consequently, the parts included in the casting mould are held together well during casting.
The invention is described in greater detail hereinbelow with reference to the attached drawings which show preferred embodiments of the arrangement and of the base part included therein according to the invention.
FIGS. 1a-1d show the assembling of a casting mould in accordance with the previously known technique. Concrete is to be poured into the casting mould in order thereby to form a pipe assembly, preferably for cables. As can be seen from FIG. 1a, base parts 1 included in the casting mould and preferably made of plastic material are first placed at a distance from one another on the ground which has already been levelled, most often on the bottom 2 of a pit or a trench. A first row of pipes 3 is then snapped into place in recesses 4 provided for this purpose in the base parts 1, after which intermediate parts 5, preferably made of plastic material and having pipereceiving recesses 6 and 7 arranged, respectively, on the underside and upper side, are placed at a distance from one another and from the base parts 1, as can be seen from FIG. 1b, and are snapped securely onto the pipes 3 in the first row already mounted on the base parts 1. The next row of pipes 3 and further intermediate parts 5 are then put into place in the same way, and, following the third and uppermost row of pipes 3, mould panels 8 are fitted in sockets 9 arranged at the outer ends of the base parts 1, as can be seen from FIG. 1c. Finally, base parts 1 are once again applied, although inverted, so that the pipes in the uppermost row snap into the recesses 4 and so that the mould panels 8 are received in the sockets 9, as can be seen from FIG. 1d. The casting mould is now ready, and after reinforcement bars (not shown in FIGS. 1a-d) have been placed, as required, in holes 10 formed on the base part or in holes 11 formed on the intermediate part, concrete can be poured into the mould so that an embedded pipe assembly for cables is obtained. For stiffening the base part, the base part has a longitudinal rib 12 and, arranged at right angles to the latter at the outer ends of the base part, side ribs 13 which are connected to the longitudinal rib. Each socket 9 is delimited by the outer surface 9' of the side rib and by a holder arm 9" which is connected to the outer ends of the base part, is preferably inwardly sprung and is arranged such that the lower end of the arm 9" is connected integrally to a part 9'" which extends from the base part essentially as an extension of the longitudinal rib 12. In the previously known embodiment, the distances between the pipes and between pipes and mould panels are assumed to be at least 30 mm in order to make it possible, inter alia, to provide room for vibration rods to be pushed down into the concrete between the pipes and between the pipes and the mould panels in the casting mould. It should be possible to dispense completely with the use of vibration rods if the casting mould is held together better and if the concrete has the right consistency (flowability).
