摘要:
The invention relates to a plant for the production of concrete, comprising a mould for a molded concrete mass (14), the mould comprising a mould base and a wall construction (2) that can be removed from said mould base. The mold base of the mold comprises an upper part (26) of a first conveyor belt (1).
摘要:
An exterior wallboard sheet includes a core having opposing first and second major surfaces. The core may include a monolithic body of aerated concrete. At least one water vapor-permeable, water-resistant face layer may be secured on at least one of the first and second major surfaces of the core. The water vapor-permeable, water-resistant face layer may include a microporous polymer layer. The microporous polymer layer may include a woven polypropylene fabric layer having a plurality of microperforations therein.
摘要:
In manufacturing cellular lightweight concrete products a huge, flat, molded body of still unhardened, semi-plastic cellular concrete mass is transferred from a first support to a second support by an apparatus comprising a vertically and horizontally movable, frame-like body-gripping device rotatable about a horizontal axis, cutting of the body, and, if desired, planing of the top and bottom surfaces thereof, being effected during the transfer by means included in the apparatus. The worked body may be deposited on the second support in its original or in an upside down position.
摘要:
A device for cutting slabs from a block of a weak material, such as not yet entirely solidified cellular concrete, comprising a revolvable cage into which the block lying upon a trolley is introduced; the cage is than rolled sidewardly and turned over 90* such that the block is resting upon a second trolley locked in the cage after which one or more cutting wires are passed through the block; finally the second trolley with the slabs is discharged and the cage is turned back 90*, so as to repeat the cycle.
摘要:
Planes parallel to the upstanding sides of the block, is performed subsequent to a tilting movement around a line parallel to an edge of the bottom of the block by means of an auxiliary supporting surface with at least one cutting wire lying upon said surface.
