Abstract
Abstract Method and device for the casting of concrete products by means of a continuous slide-casting method. The concrete mix is compacted by displacing one or several walls of the slide-castina mould structure. The wall (5) of the slide-casting mould structure is displaced along a predetermined path of movement while facing the forming member (3) forming the cavity and moving eccentrically relative its centre axis or moving back and forth around an articulated shaft.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
112 words
Method for the casting of concrete products by means of a continuous slide-casting method, whereat the concrete mix is subjected to pressure by means of a spiral screw or screws (2) and one or several cavities are formed in the product by means of one or several forming members (3) and whereat the concrete mix is compacted by displacing one or several walls of the slide-casting mould structure forcibly along a predetermined path of movement, characterized in that the moving wall (5) of the slide-casting mould structure is fitted as facing the forming members (3) which form the cavities and alter the angle of their longitudinal axes relative a certain articulation point.
Claim 2
Dependent Claim
112 words
Method for the casting of concrete products by means of a continuous slide-casting method, whereat the concrete mix is subjected to pressure by means of a spiral screw or screws (2) and one or several cavities are formed in the product by means of one or several forming members (3) and whereat the concrete mix is compacted by displacing one or several walls of the slide-casting mould structure forcibly along a predetermined path of movement, characterized in that the moving wall (5) of the slide-casting mould structure is fitted as facing the forming members (3) which form the cavities and alter the angle of their longitudinal axes relative a certain articulation point.
Claim 3
Dependent Claim
35 words
Method as claimed in claim 1, characterized in that the top wall of the slide-casting mould structure is displaced back and forth around a horizontal shaft (11) placed at the trailing end of the wall.
Claim 4
Dependent Claim
39 words
Method as claimed in claim 1, characterized in that the top wall (5) of the slide-casting mould structure is displaced back and forth around a vertical shaft (18 or 28) placed at the trailing end of the said wall.
Claim 5
Dependent Claim
37 words
Method as claimed in claim 1, characterized in that the top wall (5) of the slide-casting mould structure is displaced in the horizontal direction by means of an eccentric cam (23) revolving around a vertical shaft (22).
Claim 6
Dependent Claim
39 words
Method as claimed in claim 1, characterized in that the front end of the top wall (5) of the slide-casting mould structure is displaced along a path of movement that moves around the longitudinal axis of the top wall.
Claim 7
Dependent Claim
93 words
Device for the casting of concrete products by means of a continuous slide-casting method, whereat the device includes longitudinal walls (9,6,5), means for displacing one or several walls forcibly along a predetermined path of movement, a spiral screw or screws (2) for feeding the mix, as well as, inside the walls, one or several forming members (3) that form cavities, characterized in that the moving wall (5) of the slide-casting mould structure is fitted as facing the forming members (3) which alter the angle of their longitudinal axes relative a certain articulation point.
Claim 8
Dependent Claim
93 words

Claim 9
Dependent Claim
36 words
Device as claimed in claim 6, characterized in that the top wall (5) of the slide-casting mould structure is displaceable back and forth around a horizontal shaft (11) placed at the trailing end of the wall.
Claim 10
Dependent Claim
39 words
Device as claimed in claim 6, characterized in that the top wall (5) of the slide-casting mould structure is displaceable back and forth around a vertical shaft (18 or 28) placed at the trailing end of the said wall.
Claim 11
Dependent Claim
61 words
Device as claimed in claim 8, characterized in that the top wall (5) of the slide-casting mould structure is divided, in the transverse direction, into two or more parts (5'), which are interconnected by means of two or more longitudinal beams (27), whereat the said longitudinal beams are displaceable back and forth around vertical shafts (28) placed at their trailing ends.
Claim 12
Dependent Claim
37 words
Device as claimed in claim 6, characterized in that the top wall (5) of the slide-casting mould structure is supported on one or several vertical shafts (22), whereby the top wall is displaceable in the horizontal direction.
Claim 13
Dependent Claim
39 words
Device as claimed in claim 6, characterized in that the front end of the top wall (5) of the slide-casting mould structure is displaceable along a path of movement that moves around the longitudinal axis of the top wall.
Claim 14
Dependent Claim
53 words
Device as claimed in any of the preceding patent claims, whose side walls (6) are provided with means (30) for forming grooves into the sides of the concrete product, characterized in that the said means (30) for forming the groove are displaceable along with the top wall (5) of the slide-casting mould structure.
