摘要

The appts. produces an angular wall section consisting of a plate of hard foam material and to which closer bricks are joined, these being sepd. from each other by mortar etc. The appts. comprises two mouldings with recesses to accommodate angular closer bricks which are assembled together to form a right-angle-section mould trough. A mating mould section is placed on them so as to leave an intervening gap. The mould, of cast Al, can have a polyamide coating on the inside. The bricks can be sepd. from each other by a mixt. of sand and polyurethane. ADVANTAGE - No sticking of sections, and rapid production and installation.
