The latter allow the mould to slide along the rails 10 when the tension applied to the wires 21 by rams (28, Fig. 3) during moulding is released. The mould 32 may be inverted by a slewing crane (16, Fig. 5) via a cable 56 attached to apertured lugs 55 on the mould 32. During inversion the sleepers 58 are retained within the mould 32 by pins passing through apertures in the inserts 41. The removal of the sleepers 58 may be facilitated by spraying the moulds with oil prior to casting and by shaking and heating the mould 32 after iversion. The sleepers may be collected by a fork-lift truck (60, Fig. 5).

A method of making a cementitious component (142) in a mould assembly (100). The mould assembly (100) comprises a mould body (102) and at least one moulding element (106) for moulding an external surface of the cementitious component. The method comprises introducing cementitious material into the mould body (102) in a filling direction (F) and separating the moulding element (106) from the cementitious material (142) by displacing the moulding element (106) relative to the mould body (102) in a process direction (P) that is non-parallel to the filling direction (F). The invention provides a method in which cementitious components having cross-sections of relatively complex shapes can be made in a mould assembly using relatively few process steps. In particular, features such as recesses and channels can be moulded in surfaces that, using conventional methods, would otherwise need to be planar.

Manufactoring process of concrete elements

Pre-stressed concrete girder with trapezoidal flange - larger end of flange widens, smaller end has mounting shoulders

The width of the wider section is not greater than that of the larger end of the trapezoid flange. The girder is cast in a mould, the top rims of which are fixed, whereas the side-walls of teh flange can be extended symmetrically of the mould axis, over all or part of its height, by applying a force separating adjacent mould walls. The base of the mould consists of at least one piece integral with one of the side walls. The top sides of the mould are fixed at the position of the girder side-pieces. The side-walls may be of metal to which elastic deformation is applied, or which may be hollow and deformed by pneumatic pressure.

Arrangement for the production of longitudinal screed slabs consisting of concrete

An arrangement for casting in a mould of so-called battery design longitudinal concrete bodies with a high degree of linearity. The moulds consist of pipes of substantially circular cross-section, these being placed on top of beams which, within a frame, extend parallel to the longitudinal sides of the frame. The beams constitute lower casting boundaries in the process of casting and each two adjacent pipes constitute two lateral boundary sides in the process of casting. The underside of each mould pipe is levelled and provided with a longitudinal rail of upside-down T-shape, which is cut out at several points and at mutually identical distances. A plurality of plates each with a Y-shaped recess are placed between the top edges of the beams and at the same distances as the cut out rails. The recess matches the leg of the T-rail, and pipes are rigidly secured atop the beams by joined T-rails and plates.

SET AND FORM FOR MANUFACTURE OF CONCRETE BULBS

Improvements relating to the production of concrete beams or the like

The present specification discloses an apparatus and method for producing concrete beams for use in the construction industry. Concrete beams are conventionally made in suitable moulds in a factory, the beams being removed from the mould and transferred to the construction site. However, removal from the mould and transit can cause the beams to be damaged, besides adding to the production cost. The present invention provides an apparatus which is manhandlable without the need for lifting gear, and which can be used on site, thereby reducing production cost and the possibility of damage. The apparatus comprises a number of vertical supports (5) between which horizontal support members (7) extend. Elongate mould members (17) rest generally horizontally on the support members (7), abutting one another so as to define a number of adjacent, parallel, generally U-shaped channels (19). In use, concrete is poured into the channels (19) and after hardening the mould members (17) are separated, it being a relatively easy operation to release the L-shaped mould members (17) from the beams with little, if any, damage.
