Definitions
- the Swedish patent application 8001663-7 describes a method for producing concrete floors of high quality as regards planeness and rational construction.
- use is made of slide tracks for the vibrating beams employed in the process of producing the floor, by way of permanent moulds.
- continuous reinforcement can be achieved, which means that shrinkage cracks do not arise in the floor along these slabs.
- Moulds can be produced from thin metal sheeting bent to the required cross-sectional shape. The sections are then connected by point-welding. This gives rise to. heat stresses causing deformation of the sheets with disastrous consequences for the use cf the resulting slabs. Also injection-moulded aluminium has been tried but after handling the condition of this product became quite bad. Once this was the case it was less possible to produce correct slabs. In addition aluminium is, after all, subject to the disadvantage that it is attacked by concrete, so that the surface of the product becomes rough.
- the choice may be made entirely according to the capacity of lifting devices at the place of work (trucks or overhead cranes).
- beams extend at equal distances, i.e. parallel to the longitudinal sides.
- the pipes are then placed in such a way that the beams constitute the underside of the mould.
- the invention now aims a ⁇ an arrangement by which the pipes are secured and aligned in such a way that the linearity of the pipes is at least as good as that of the bears.
- the cross- section of which is nearly circular, that part of the periphery which is to form the base is levelled somewhat. This levelling operation is effected between 30-90 degrees of the centre angle. At the centre of this levelled face a rail is fixed which consists in an upside-down T.
- the continuity of the rail is broken by gaps at equal distances. These breaks occur e.g. at a rate of one per metre and with a length of 5 cm. This can be varied within wide limits, and the dimensions given at this point are mentioned only to facilitate comprehension of the function.
- On the bed of beams and between the beams are placed, at the same distances as the breaks in the rails plates, the top edges of which are located edge in edge with the top edges of the beams.
- the plates are provided with a Y-shaped recess with the opening so arranged that the web of the T-shaped rail fits inside the Y-shaped recess.
- the expanding part of the Y-shapes is used for controlling the rail, in case non-linearities in the pipe may have prevented simple insertion.
- Figure 1 shows a cross-section illustrating the function of the above-named rail and the recessed plate.
- (1) are two adjacent beams. On top of these beams is located a pipe (2) with a levelled part of the periphery (3). Attached to this pipe can be seen the T-rail (4) which, subject to certain breaks, extends along the pipe (2).
- the plate (5) is provided with a Y-shaped recess (6) subdivided into the inner section (7) and the expanding outer section (8).
- Figure 2 shows the plate by itself in a different projection, use being made of the same reference numbers as in the previous case.
- the bed of beams is made of strong beams and that the planeness is accurately adjusted.
- the entire bed of beams is then placed on three or several bearing brackets which in turn are provided with vibration-generating devices, all with a view to ensuring satisfactory casting.
