摘要:
A method of producing a plurality of metal-reinforced panels in a molding box (10) having a cavity defined by a bottom wall (16), two side walls (14,15) and two front walls (12, 13); a number of reinforcing metal elements (17, 18) is arranged in the cavity with partitioning means between adjacent elements (17, 18); a flowable and hardenable material, such as a concrete mix, is fed into the cavity and is allowed to harden therein to form the metal-reinforced panels; the reinforcing metal elements (17, 18) each have a generally stratiform biplanar structure (100) and are formed of at least two distanced metal sheets (101, 102) maintained in a substantially parallel and mutually supporting arrangement. Preferably, this method is carried out in a tiltable molding apparatus (7) having a molding box (71) and at least one fluid-cushion (78) capable of varying its outer shape (V,. V 2 , V 3 ) in response to varying the amount of fluid within the cushion (78); the cushion (78) rests on a support surface (77) and is connected with molding box (71) for a tilting movement (F, Z, E) of molding box (71) by variation of the amount of fluid within the cushion (78).
摘要:
The invention is concerned with a method to build a cast concrete spaced structure of large dimensions wherein one or more walls, mutually enclosing an angle, are cast and thereafter tilted. A first wall (2) is cast flat lying and thereafter erected whereafter a perpendicular second wall (6) is cast flat lying against the first wall. Thereafter the arrangement of first (2) and second wall (6) is erected such that both these walls extend upwardly, whereafter a perpendicular third wall (7) is cast flat lying against the first (2) and second wall (6). Use is made of a table (8) which is supported such that it can pivot around the horizontal to erect the wall, wherein an edge of the table (8) lowers and/or the tables displaces. During erection, the centre of gravity is displaced by filling or emptying a ballast tank (11,12) such that a tension force is present in a cable (10) used for tilting.

The present invention provides a split mould (10) for particular use in moulding large concrete components (12) having a weight bias to one end, the split mould (10) comprising a pair of mould sections (14, 16) separable from one another and defining a mould cavity (20) therebetween, and a guide member (18) which is adapted to allow the mould (10) to be rolled into an inverted position, in order to allow the mould (10) to be emptied.

摘要:
A method for erecting a building or parts of the same. To this end, the invention provides that repetitive concrete filigree structures are erected with precast concrete parts. The precast concrete parts fabricated by concrete mixing plants, which are located at building sites and/or near building sites, are shuttered without joints in a battery rotational shuttering method and/or on a base bottom.
