Prefabricated wall form and production method therefor

Abstract

The specification discloses a prefabricated wall form adapted to be left in place to provide surfaces after filling said form with a filler, for example, cement. The wall form comprises at least a pair of spaced panels interconnected with a tie-wire mesh structure. The panels consist of at least one layer, preferably, at least two layers of different materials. The tie-wire mesh structure is embedded in the panels and extending laterally within each panel and having linking portions from one panel to the other. The panels may be made of cement mixtures. There is also disclosed a method for producing the prefabricated concrete forms. According to the method, at least a pair of panel forming webs of cement mixture are extruded. After feeding tie-wire mesh structures mounted on mould members between the pairs of webs, the whole structure is pressed to embed the tie-wire mesh structures into the webs. The whole structure thus pressed together is then subjected to heat-curing, for example, steam-curing to set the cement mixture and then cut in a predetermined size. Thereafter, the mould members are removed from the wall forms thus produced. The prefabricated wall forms of the invention are suitable for a long-distance transportation and for a short construction period. They may be assembled without need for highly skilled labor or special equipment.
