11 Claims.

This invention relates to a dampproof Wall structure in general and particularly to ooring and also to the method of constructing the dampproof structure of the Wall or the dampproof structure of the ilooring made according to the present invention.

Among the objects of the present invention, it is aimed to provide an improved dampproof Wall structure and particularly a dampproof flooring in which there is interposed between the Sub-Wall or ooring structure and the main Wall or flooring structure an uninterrupted continuous layer of non-corrosive and dampproof metal and Wood, rubber, linoleum, cork or the like and strips of a dampproof metal such as sheet copper of about .0027 inch gauge bonded together by dampproof uninterrupted sweated joints with the sheet metal bonded to the substructure by a Water-proof adhesive, such as asphalt and after the joints of the metal strips have been sealed, then the main wall structure or flooring, such as wood, rubber, linoleum, cork or the like bonded to this sheet metal layer by an adhesive, such as asphalt cement or the like.

It is still another object of the present invention to provide a method for constructing the of a wall or ilooring made according to the present invention which consists in spreading an adhesive such as asphalt upon the subwall structure or flooring, then laying the sheet metal strips With the adjacent edge of each succeeding strip overlapping an inch or more of the preceding sheet metal strip so that such overlapping portions are free from asphalt and form pockets into which there are then inserted continuous strips of sealing compound and thereupon the heat applied to the outer face of the overlapping flanges and a cooling medium applied immediately thereafter so that the sweated bond between the sheets may be effectively sealed with a minimum amount of labor and at a minimum cost.

These and other features, capabilities and advan drawing in which Figure 1 is a cross section of a wall structure or ilooring made according to the present invention;

Fig. 2 isa cross section of a combined wall (Ol. l2-126) structure and flooring made according to the present invention;

Fig. 3 is a fragmental cross section of another embodiment of wall structure or flooring made according to the present invention;

Fig. fi is a perspective View illustrating one method of constructing the dampproof structure of a Wall or flooring made according to the present invention; and

Fig. 5 is a perspective View illustrating another method of constructing the dampproof structure of a wall or flooring made according to the present invention.

In the embodiment shown in Fig. 1, there is provided a sub-Wall or ooring structure l composed of concrete or the like, a main wall structure or flooring structure 2 composed of Wood, rubber, linoleum, cork or the like and an intervening dampproof sheet metal layer 3 composed of a plurality of thin non-corrosive moisture or dampprcof metal strips, such as copper sheets of about .0027 inch gauge by thirty inches wide, the overlapping longitudinally extending edges of which are bonded together by an uninterrupted continuous dampproof sweating joint or seal.

The sheet metal layer 3 is preferably bonded to the subvvall structure l by a waterproof adhesive, such as an asphalt layer 4 and the main wall structure 2 is preferably bonded to the sheet metal layer 3 by an adhesive, such as the asphalt cement layer 5 or the like depending upon the character of the main Wall structure. As an instance, if the main Wall structure 2 is composed of wood, a mastic binding is used; if composed of rubber or cork a rubber cement is used and if composed of linoleum then a linoleum paste is used.

The Wall structure constructed according to Fig. 2 consists' in a subwall structure 6 composed oi concrete andv embraces the iiooring structure I and vertically extending wall structures 8 and 9. In this embodiment, the Waterproof adhesive, such as asphalt is first brushed or spread over the upper surface of the flooring structure l and the inner faces of the wall structures 8 and 9 and then the strips' IfEJ of sheet metal laid onto such adhesive, Where-uponit Will immediately adhere to the o'oring structure l and wall structures il and 9.- When so laying the sheet metal strips lil, the longitudinal edge of each succeeding metal strip preferably overlaps a longitudinal` edge of a preceding strip so as to form a flange or border of a succeeding strip of about one and a half inches Width overlapping the flange or border Cil of a preceding strip of about one and a half inches in width. After the strips I0 are so laid and adhered to the substructures 1, 8 and 9, the overlapping flange will form a pocket. The pocket so formed constitutes an important part of the present invention.

In this pocket an uninterrupted continuous length of round sealing wire or flat sealing ribbon is placed, the pocket formed by the overlapping flanges facilitating the rapid location of the wire I I without the use of any measuring instruments or any position defining devices. Thereupon, it will only be necessary to apply heat to the outer face of the flange of a succeeding strip I0 as aninstance by passing an ordinary sadiron I2 across the same. Preferably so that the joint may be cooled and thereafter sealed as quickly as possible, a cooling roller, such as the roller I3 may be passed across the outer face of the overlapping iange immediately following the sadiron I2.

In the embodiment shown in Fig. 5, instead of the round sealing wire I I, there is used a flat sealing ribbon I4 which cooperates still better with the pocket formed by the overlapping flanges of adjacent strips I@ to maintain its position before and during the sweating operation.

In this embodiment also instead of the sadiron a gasoline torch I5 is used to apply heat to the overlapping flanges and this torch I5 followed by a cooling roller I6.

In the embodiment illustrated in Fig. 3, the metal strip I'I .along the corner of a room between the licor substructure I8 and the side wall substructure I9 is bent back over the main flooring 20 to form a U-shaped end and thereby seal the edge of the flooring adjacent the wall structure I9 and also extends up at 2| along the inner face of the wall structure I8 above the main flooring 20 to .any desired height.

The sealing wire II and sealing ribbon I4 are preferably acid lled, each consisting of a shell composed of tin and lead enclosing an acid filler.

With the present invention, it will be seen that an effective uninterrupted continuous waterproof layer will be interposed between the subwall structure and the main wall structure or between the subilooring structure 4and main flooring structure, which will nd especial utility with a room constructed below grade to prevent the admission of ground moisture. When the waterproof layer is composed of thin sheet copper, there will be provided a layer which will be immune to attack from moisture as well as prevent the passage of moisture therethrough to the main flooring and in addition there will be formed an effective lining or layer for preventing the passage of vermin, termites, and rodents by way of the wall structure or floor structure so equipped.

It is obvious that various changes and modifications may be made in the structure and in the steps of the method aforesaid without departing from the general spirit of the invention set forth in the appended claims.
