(Cl. Mill-34) 5 iliaiins.

This invention relates to a building structure and more particularly to a roofing and siding structure.

The object of the invention is to provide a novel and improved roofing and siding structure which allords highly efficient insulation against heat and cold and which may be economically manufactored and erected with more facility and at less expense than prior comparable structures of which I am aware.

With this general object in view, and such others as may hereinafter appear, the invention consists in the building structure and in the various structures, arrangements and combinations of parts hereinafter described and particularly defined in the claims at the end of this specification. 7 v

in the drawings illustrating the preferred embodiment of the invention, Fig. l is a perspective illustrating a portion of a roof structure cinbodyine' the invention; Fig. 2 is a detail taken on the line 2-2 of Fig. i; Fig. 3 is a cross-sectional detail taken on the line t-3 of Fig. 1; Fig. t is a detail of the intermediate support; and Figs. 5 and 6 are sectional details illustrating corrugated and Mansard types of corrugated sheets forming a part of modified forms of the building structure, as will be described.

In general, the present invention contemplates a building structure embodying corrugated sheet members and underlying preformed insulating sheets, both being operatively supported in a metal framework of special design which enables the erection oi both the insulating members and the overlying and spaced corrugated members from the top or the exterior of the roof or siding of the'building to the end that necessity for scaffolding and the like may be avoided during the erection oi the structure. The resulting insu lated construction provides a speedily erected, dry, and light-weight insulated structure which is not afiected by freezing weather, and. when erected the interior insulating panels provide a neat appearing interior which can be easily painted by spraying or otherwise with any desired color. The air space between the insulating panels and the exterior corrugated sheets enhances the insulating effect and further provides ventilatlon between these parts.

Referring now to the drawings, the invention has been illustrated in Fig. l as embodied in a roofing structure wherein it represents the purlins upon which the present improved insulated assembly is erected. The present assembly comprises a special metal framework erected upon the poi-lino in such a manner as to accommodate and support preformed insulating panels it and superposed corrugated roofing or siding members iii so as to transmit the roof or siding load through the framework independently of the insulating panels to the purlins or other metal framework upon which the special supporting iramework is erected.

In the preferred embodiment of the invention the corrugated roofing or siding members it may comprise any of the load supporting preformed roofing or siding members now upon the market such as corrugated sheet metal, corrugated asbestos-cemcnt sheets, and corrugated protected metal sheets such as are illustrated in the patent to Robertson No. 1,277,755. These commercial roofing or siding sheets it are of sufllcient length to span one or two purlins and usually are made in standard widths, and. accordingly a special supporting framework is first erected upon the purlins, or upon the supporting framework forming the sides of the building, comprising Z-shaped metal bars fill of a width slightly less than the width of the roofing or siding sheets it employed and which are welded or otherwise secured upon the upper flange of the roof purlins or upon the corresponding elements in the side wall frame of the building. In some instances, particularly where the purlin spacing is long, it may be desir able to provide an intermediate support at a point between the adjacent purlins such as an inverted T-shapecl metal member 23?. The sides of the special framework are formed by specially designed supporting members 23 comprising an upper member 2 3 and a lower member 26 separated by fiber or other insulating spaced memhers it so as to enable the insulating panels it to be dropped into place to be supported at their ends upon the lower flanges (ill of the Z-bars 2d and upon one of the flanges of the intermediate inverted IF-shaped support 22 if such be provided. In those instances where the purlin spacing permits, the ends of the insulating panels it may be supported at one end on a lower flange til of a Z-bar it and at their second ends upon the upper flanges of the purlins themselves. The sides of the insulating panels are supported upon the lower members it of adjacent supporting members 23 as shown. The preformed weatherproofing roofing or siding members herein shown as comprising corrugated metal members I t are supported at their sides upon the upper member 2 3 of the supporting members 23 of the framework. The marginal corrugations oi the corrugated roofing or siding members are lapped over upon one another, both being supported accuser upon the upper member 26 of the supporting members 23 of the framework. The spacing between the upper and lower members 26, 26 is such as to provide an air space between the under surface of the corrugated roofing or siding mombers and the insulation. The end laps oi the corrugated members are preferably made so as to be disposed over the purlins or equivalent cross members of the framework oi. the side oi the building.

As shown in Fig. 3, the insulating members 28 may comprise insulating tubes such as hard iiber tubes, and the upper and lower supporting membars 24, 28 may be secured thereto by screws 3?, 38 as shown. The corrugated roofing or siding members in their overlapping relation may be fastened together by the usual screws so along the side laps thereof. The overlapping ends of the sheets may be secured by additional screws I2 screwed into the upper flange of the Z-bars so.

It will be observed that the above described construction provides complete insulation against the transmission of heat or cold by conduction so that the formation of condensation upon the under-surfaces of the supports 26 is reduced to a minimum. In addition, the described construetion provides a dry lightweight insulated roofing or siding structure, which may be erected without scafiolding and in a speedy and economical manner in which preformed insulating sheets of commercially available materials, such as glass or metal wool insulation may be used thus providing an incombustible structure. After the roofing or siding has been erected the insulation provides a neat appearing interior surface which can be easily spray painted with any color desired, and the character of the insulation may be such as to provide the structure with acoustical properties.

Another feature of the present invention is I that the air space between the insulating sheets and the corrugations of the roofing or siding material provides ventilation, reducing to a minimum any condensation and contributing to the life of the structure. The entire structure may be erected from the exterior of the building, and this feature contributes to the economy with which the tructure may be erected.

While the preferred embodiment of the invention has been herein illustrated and described it will be understood that the invention may be em bodied in other iorms within the scope of the following claims.
