Abstract: 683,805. Building construction. LAGOS, M. C., and CURUTCHET, M. A. April 14, 1949, No. 10218/49. Classes 20(iii) and 20(iv) A building construction comprises ground-floor wall units or sections of one storey height of moulded c ementitio us material, each being of similar overall dimensions and consisting of a rectangular frame 1 mullioned 3 and transomed 2 to provide through openings 4 for receiving cover plates 5, and. the bottom and top members 6, 8 shaped respectively for keying the units to a concrete &c. foundation and for receiving concrete and reinforcement 14 to provide a continuous reinforced beam at the top of the units. The parts 2, 3, 6 and 7 may be reinforced. The bottom member 6 is shown as of dovetail form and may be coated with waterproof material to provide a damp course between the wall and the foundation. The side members 7 are of L-section, and the units s are tied together laterally by bolts 15 passing through the side members, the space between the members being filled with mortar &c. containing a damp-proof substance. Fig. 1 shows a window frame c fitted in a unit by means of a shoudered channel-shaped sill member b which fits the transom 2, an upper member similar to b, and side members comprising a part d which fits the mullion 3 and fits into a channel section part e having a shoulder for the frame c. Other arrangements are shown with parts of the mullions and transoms omitted for the reception of windows and doors of different sizes and arranged in different positions. Figs. 43, 47 show units for the construction of interior walls &c., the openings 4 and parts 6 and 8 having the same dimensions as in Fig. 1, and the parts 6 and 8 shaped as in Fig. 1, but the mullions 11, transoms 10 and side members 9 being shaped as shown. Fig. 49 shows a twostarey construction in which the upper unit comprises a channel section upper member 14a, mullions 17a, and a base member 17 of angle section providing for the seating of the reduced end of a floor joist 16 on the upper member of the lower unit. Fig. 50 illustrates a unit fitted with a door 13d and window 13c, the counterframe comprising side and upper members each consisting of two parts 13b, 13a which fit against the mullions and upper transom, and a sill member 13f which fits the lower transom and has a flange fitting against the side edge thereof. The panels 5 may be made of vermiculite, pumice stone, volcanic lava, or porous concrete, and the space between panels may be filled with heat &c..insulating material, such as cork, glass wool &c. or house heating, gas, water, electric &c. conduits. Normal inner and outer finishes such as tiles, plaster, paper, paint &c. may be applied. Figs. 52-59 show modifications and arrangements with two units side by side, Figs. 52, 53, two units at right angles, Figs. 54, 55, two units side by side joined with a third unit at right angles thereto, Figs 56, 57, a junction of four units, Fig. 58, and two units in the same plane one on either side of and at right-anges to a third unit, the junction occurring at a mullion of the third unit, Fig. 59.
