Abstract: 461,038. Building structures ; ventilation; walls; roofs; metal framework. SMITH, P. M., and MILLIGAN, F. S. Jan. 18, 1936, No. 1719. Convention date, Aug. 24, 1935. [Classes 20 (ii), 20 (iv), and 137] A building structure comprises a plurality of individual wall frame units 3 secured together side by side, heat-insulating material 24 secured to the outer faces of these units by means extending inwardly through the material into members 21 of heat-insulating material extending between, and secured to, members of the individual frame units, and an overlying wall surface 29 applied to the material 24. The metal units 3, Fig. 2, are each of inverted U- shape, being formed of legs 4 and a horizontal cap 5 which are of channel cross-section and are welded together. The members 21, which are preferably of wood and of the same width as the cap 5, are inserted between the legs 4 of each unit and are secured in place by pins or nails passing through the flanges of the legs. The lower ends of the legs are provided with angle brackets 9 bv means of which the unit is secured by bolts to the foundation or to the cap 5 of an adjacent lower unit. The units 3 are secured side by sid e b y bolts extending through the brackets 9 and the legs 4 of adjacent units, and may also be connected by bolts, wedges or clips joining adjacent legs at intermediate points in the height thereof. The insulating material 24 may be in slab, sheet or other form, such as batts of rock wool, and as shown in Figs. 18 and 19, consists of cork slabs secured to the outer faces of the units 3 by clips consisting of a slotted plate portion 25 and a hook 27. Such a clip is applied, preferably, over the junction between adjoining slabs, and a nail 28 is inserted through the slot 26 in the portion 25 into the member 21. The hook 27 is adapted to grip a horizontal strand of a wire - mesh fabric 30, which serves as a base for the subsequently-applied stucco, plaster, cement or like composition 29. A modified clip is provided with two identical hooks 31 and an intermediate hook 32 as shown in Fig. 25, and the wire-mesh fabric is gripped between the hooks 31, 32. When the wall is provided with a brick facing 33, Fig. 21, the clip is provided with an outward extension 34 having a hook 35 which is adapted to grip a rod 36 embedded in the mortar joint between courses of bricks. The inner face of the wall may consist of plaster 39 applied to gypsum boards 37 as shown in Fig. 18. The upper units of a wall may be provided with parapet frames 12, Fig. 2, having brackets 14 for connection to the uppermost wall units. Warm air may be conducted to the interior of the building through successive wall units which are provided with communicating apertures in the caps 5 ; alternatively, the air may be conducted through conduits which pass through the apertures in the caps 5. The flanges of the caps 5 may be reinforced by straps 7 as shown in Fig. 15, and apertures 8 may be provided in the legs 4 to permit the passage of electric or other conduits. Joists 16, preferably of truss construction, are provided for supporting a concrete floor 17 or roof deck 18 as shown in Fig. 1. The roof deck 18 may be provided first with an overlying insulating layer 18<a> and then with a covering of roofing-material 19.
