Abstract: 1,011,916. Dwelling houses. C. VAN DER LELY N.V. March 30, 1962 [March 30, 1961(3)], No. 24301/65. Divided out of 1,011,913. Heading E1A. A prefabricated section for a building comprising one or more such sections and each section comprising a floor, a ceiling and side walls interconnecting the floor and ceiling and enclosing all or part of one or more rooms, is formed by constructing two vertical frameworks from metal beams 35, 41 or 36, 48, Fig. 4, and vertical tubes 39, 40 or 46, 47, and thereafter forming a layer of rigid dense material between the two frame beams 35 and 41 or 36 and 48; interconnecting the beams 41, 48 together and the beams 35, 36 together as by upper and lower beams such as beams 120, 121; fixing the floor supporting structure of joists 75, 76 to the lower connecting beams 35, 37, 38, 36, and then fixing a roof or ceiling supporting structure to the bars connecting the upper beams 41, 45, 48. In Fig. 4 each vertical beam such as 40 has horizontal extending arms 103, 105 to which are welded the interconnecting bars such as 120, otherwise as described in Specification 1,011,914, the interconnecting bars may be each in one piece. Struts such as 61, 62, 64, 65, 66 may be secured within the beam frame so as to be carried within the wall and a door frame 212, Fig. 5 may be included in a beam frame and supported by struts 215, 216 before the wall is formed in the frame. The outer walls may be formed from two parallel spaced blocks of foamed concrete with a layer of mortar therebetween, or the blocks may be of masonry 242, Fig. 9, built up from blocks cemented together by mortar. An ornamental layer 244, Fig. 9 is applied to the inner sides of the walls of a section and an insulating layer 310 with a waterproof facing sheet is applied to each of the exterior surfaces of the walls after the walls have been incorporated in the section, and after erection of the section in the building a facade 311 of corrugated sheeting is applied, the junction of two sheets 311, being covered by a covering sheet 312 which is nailed to wooden beams. Tubes 39 and 307 are end tubes of adjacent sections and these have radially projecting strips 306, 308 arranged symmetrically with respect to the plane of connection of the sections, an elastic sealing strip 309 being provided between the strips 306, 308. The fastening of an inner wall 314 to the beam 37 of the frame is shown in Fig. 10. T-section beams 320, 321 are welded to the beam 37 with the webs of the T-upright and spaced apart equal to the width of the wall minus the covering layers 318, 319. The floor 368 rests at one side on limb 323 and a skirting board 329 is fixed to the floor. The floor is supported on its other sides in a similar manner, and is nailed to joists such as 75, 76. Figs. 4, 10 which are secured to joist plates such as 333, 335, welded to the frame beam 37 &c. The ceiling 270 is nailed to a beam 271 connecting two tubes such as 39, 43 and 40, 44, at the upper ends. The manner of securing the ground section to the foundation beams and an upper storey to a lower storey is described in Specification 1,011,914 and a cover plate for covering the space between an upper and lower storey and for directing rain water running down an upper storey wall away from the lower storey wall, is described in Specification 1,011,913. A prefabricated slab and the method of mounting it to close the space between the ground section or sections and the ground is described in Specification 1,011,915.
