494,008. Walls; blocks. BOMGREN, A. F. April 15, 1937, No. 10787. [Classes 20 (iv) and 87 (i)] A method of building walls from storey-high blocks 10, 15, which are of parallelepiped shape and are cast from porous concrete or other mouldable material having a low specific-weight and low heat-conductivity, consists in erecting the blocks on a base, such as a foundation wall or lower storey, in such a manner that thin through going and open joints are provided between adjacent blocks, and between the blocks and the base, steadying the blocks in an adjusted position in which plane outer and inner wall surfaces are formed, whilst maintaining free play between the opposing surfaces at the joints, and finally uniting the blocks with each other and the base by means of a binding mass which fills the joints. The joint spaces are provided by means of spacers 12 which are preferably of fibrous material and may be secured to the blocks during casting of the blocks, or by nailing or otherwise securing them to the cast blocks. The spacers 12 are placed on the edges of the blocks intermediate the faces of thereof. To form door and window openings, suitably-shaped blocks 10, 13, 14 are provided as shown in Fig. 1. The upper inner edges of the blocks 10, 12 are recessed to receive a flat iron plate 17 which, as shown in Fig. 9, is screwed to the blocks for the purpose of stiffening the structure and supporting floor beams 23 adapted to be bolted to the plate 17. For partition walls, the plate 17 extends across the full width of the wall and is bolted to the corresponding plate 17 of the outer walls. Adjacent blocks are secured together at the base by iron cramps driven into the blocks. After the blocks have been secured together in adjusted position, the joint spaces are sealed on the inner and outer sides by means of narrow strips 42, which are arranged as shown in Fig. 9 and may be formed of cement positioned by a spatula or trowel so that entirely smooth wall surfaces are obtained. After setting of the sealing strips 42, the joints are filled from the top with cement which flows through the vertical and horizontal joints, except in so far as these joints are stopped off by filling members placed at intervals in the horizontal joints. If desired, the joint material may be introduced at the time of erection of the blocks, being of such a character that it will not solidify until the blocks have been adjusted to their correct positions. The blocks, which have plane and parallel side faces and plane edge surfaces at right-angles to the side surfaces, may be faced exteriorly with a plaster or other covering.
