Abstract: 390,595. Walls, columns, &c. AIREY, SIR E., 7, Blenheim Terrace, Woodhouse Lane, Leeds. Jan. 25, 1932, No. 2189. [Class 20 (iv).] A reinforced-concrete wall, column, or like structure comprises domes of expanded, perforated, or woven metal secured in position by concrete poured around the outsides of the domes between them and shuttering, only a small portion of the concrete passing through the meshes or like openings in the domes so that no metal is exposed in the finished structure. Furthermore, a pillar or like structure comprises similar domes arranged vertically with their crowns facing inwardly towards each other and concrete poured between the domes, base pieces connecting the edges of the domes and defining the external surface of the pillar. In the construction shown in Figs.' 1 and 2, representing respectively a sectional plan and elevation of a wall, vertically arranged domes are provided each having flanges 2, 3 for engagement by bent-over edges of a base 6. The ends of the domes are closed by pieces of expanded metal or other material 9. The domes during construction of the wall are retained in position by shuttering placed against the bases 6, and shuttering is also placed at a distance from the crowns of the domes. Vertical reinforcing rods 8 and horizontal rods 15 may be provided. Concrete is poured around the outside of the domes, and when it has set the shuttering is removed and a layer of plaster c may then be applied to the bases 6. The bases may be replaced by strips of hoop iron. Each horizontal row of domes is cemented in position in succession. In a modification the flanges on the edges of the domes and the bases 6 are dispensed with, and one side of each dome is formed with a lip for engaging the other side of an adjacent dome. In a further modification each horizontal row of domes is arranged with the crowns alternately in opposite directions. In a further modification the domes are spaced apart by distance pieces and the facing of plaster c is replaced by asbestos or compound board. In the wall shown in Fig. 3, two rows of domes with their bases abutting are provided. The rods 8 are braced together by binding wires 17. Fig. 7 shows a wall with an abutment 21 formed by employing domes with crowns arranged as shown, the rods 8 being braced by wires 17, 22. Fig. 10 is a sectional plan of a column, four domes being provided between the crowns of which concrete is poured. The bases 6 may be covered with plaster c. In a modification the bases, which do not touch each other at adjacent edges, are embedded in the concrete. In a further modification two of the oppositelylocated domes shown in Fig. 10 are dispensed with, being replaced by concrete. In the arrangement shown in Fig. 12, the domes are located at the corners of the column, each with two base pieces 30, 31. The invention may be applied to inclined walls or to domed roofs. The cavities formed in the structures may be utilized to house water or other pipes or to accommodate cupboards or show cases, in the former case the base pieces of the domes being formed each in two overlapping portions adapted to be bent apart for the insertion of the pipes. Specification 365,671 is referred to.
