Generall speaking, buildings, particularly houses, are constructedatthe building site, the various materials employedjbeing'cut to size and erected on the spot. However, it is of great advantage to employ st be made in a factory speciallyequipped and manned for their most economical manufacture en masse and subsequently'shippedto distant sites forassemblin' Objects It is, therefore, an object of the present inven tion to provide a form of construction which lends itself to the prefabrication in a manufacturing establishment of parts which can be eventually assembled togetherin a simple manner at the building site. It is a further object of the invention to provide structural Darts, subassernblies an'd'assemblies of unique and novel form.

With these and'other objects in View, the invention is preferably embodied in a type of building construction employing a'number'of sections which can be assembled together to form wall, floor and roof units. All these-units are preferably of a similar construction,- each-being 'made up of sections provided witha facing of aparticular sheet material' of to be described inmore detaiLand a lining either of the same type of sheet or' of conventional flat material. The linings and the facings'arelspaced apart and connected byspecial supporting meme bers or studs which are provided .with tenons adapted to fit into the dovetailed depressions in the sheets. At the junction' betweennadjacentsections, special cover. joints are provided. .to fit over the dovetailed "projectionsat the vjointspztoc key them together and to rendercthem impervious. Atthe corners ofthe buildingisp'ecial sheeting and cover joints are also provided-:1 I

Insulation I05 may be placed between the lining and facing of the units. It is preferable that this insulation *does not fill the entire space but that 'aigapis left'between the facing and the insulation as shown in Figure 3,

Another modification in'structure is shown in Figure 6. In this case ,the wooden studs joining the facing and lining together are replaced by a metal stud M of the cross section shown, the stud having a tenon H engaging the recess of the facing in the manner above described. The stud M has fiangesllli which are connected, in this case, .to a horizontally orverticallyextending slat H to which thelining is attached.

The material from which the elements of the structureare made may, of course, be widely varied}. The sheeting maybe of metal, plastic, glass, paper or any other material lending itself to the structure as described.

The space between the facing and lining has been shown as filled with fibrous insulating material. This space may be filled with concret or other material which gives both insulation and structural strength. Alternatively, the spacing studs may be employed to give structural strength and to leave space for insulating material such as cork, sawdust, rock wool, aluminium foil, fibre board, etc.

The outer faces of the corrugated sheets may receive stucco, plaster, etc., so as to provide normal outside and inside wall finishes. A stucco of weak mixture with large proportion of aggregate may be used which is not so liable to crack as a strong mixture but readily allows rain water to penetrate. Because of the impenetrable nature of the cover joints, the penetration of rainwater through the stucco is not of the same importance as in ordinary construction which does not have impenetrable joints behind the stucco.

The method of construction described is featured by the possibility of breaking up the materials for building a house, etc., into fiat sheets which can be joined together at the site by sliding studs into sockets in the Wall sheets.

Strength is obtained in thin sheet material by sliding a member or stud with dovetailed edge into a. dove-tailed corrugation in the sheet, thus supporting the sheet through its entire height and making it possible because of its close connection with the stud to hold considerable downward thrust of a roof or similar weight placed on it.

The cover joints not together but form a cover to the joint which is impervious to water. They are not observable as in the case of strips of wood or metal which are normally used to cover joints between sections. By their use the exterior of a building is made to look like a continuous corrugation Without joints.

While the description has been in terms of a building, the sheeting and attendant structure may be employed in the manufacture of fencing or for similar purposes.

It will be understood that, without departing from the spirit of the invention or the scope of the claims, various other modifications may be made in the specific expedients described. The latter are illustrative only and not offered in a restrictive sense, it being desired that only such limitations shall be placed thereon as may be required by the state of the prior art.

The sub-titles used throughout the specification are merely to simplify reference thereto and should otherwise be disregarded.
