In certain building structures it is preferable for the sake of appearance to employ finishing strips of various kinds, as for instance, base boards. The conventional form of base boards is, however, undesirable in certain types of buildings, particularl in schools, hospitals, and other like buildings, for the reason that with such constructions a horizontally extending ledge or shoulder is provided upon which dust, dirt, or other foreign matter collects. It has been suggested, to my knowledge, to provide a sheet metal base board in flush relation to the surface of the wall but this construction involved a permanently positioned base board and is not adapted to be constructed of wood. Sheet metal for such uses is not favored because it does not result in the rich finish that is capable with a wooden member, and furthermore, is more difiicnlt and expensive to refinish than a wooden member and is more expensive in initial cost. In accordance with the present invention, I provide a construction by which a wooden base board or other finishing strip or member may be incorporated in a wall construction in substantially flush or in inwardly offset relation with respect to the surface of the wall, whereby the objectionable dust-catching shoulder is eliminated, and, further, it may be secured in place or removed with a minimum amount of time and expense. Furthermore, the construction is such as to permit breathing of the floor when employed in connection with a base board without affecting the operativeness of the structure in any manner whatsoever.
It has also been suggested to my knowledge to provide behind a base board a space adapted for extending conduits, wires, or other like members, and the present invention provides a construction by which such space may be readily provided.
Furthermore, the present invention is applicable to either masonry or composite walls and is capable of modification to meet vari ous conditions such as may be met in structures of various types.
Referring to Fig. 1, I show a construction particularly adaptable for use in connection with masonry walls. In this figure the numeral 25 represents a floor of concrete, or other like material. As is usual in such constructions, wooden stringers such as 26 are embedded in the concrete 25 in order to serve as a means for securing the wooden floor covering 27 in place. Where a wall is to be provided I prefer to first build up a section such as 28 of a height substantially equal to or greater than the height of the desired base board to be employed. In order to provide an ample conduit chamber I prefer to make this section 28 of relatively less thickness than the final thickness of the wall, and in order that it shall be of ample strength to carry the weight which will be imposed upon it I prefer to form it of some material having a relatively high compressive strength, such as brick or the like, as illustrated. I then position upon the portion 28 of the wall an inverted channel sectioned member comprising a base 29 and downwardl turned lateral side flanges 30, the side anges 30 being preferably spaced from each other a distance equal to the desired final thickness of the wall and preferably equally spaced outwardly from the sides of the portion 28. The base portion 29 of this member is preferably formed of a plurality of apertures such as 31 therein,-best illustrated in Fig. 2, and upon it the body 32 of the wall above it may be built. The apertures 31 permit a suitable bond to be established directly between the wall portion 28 and the wall portion 32. The body 32 is then preferably faced with a plaster coating 33 which is brought out flush with the outer faces of the flange portions 30. A base board 34, preferably of wood, is then inserted, as indicated in dotted lines in Fig. 1, its upper edge being received back of and in contact with the inner face of the corresponding flanged portion 30, and it may be secured thereto by screws such as 35 inserted through openings such as 36 (see Fig.2) in the flanges 30 and threaded into the base board 34. The base board 34 is preferably of such a hei ht and is preferably secured in position so t at its upper edge terminates short of the base portion 29, and its lower edge terminates short of the floor covering 27. Each base board is also provided on its inner surface and adjacent the lower edge thereof with one or more spacing members 37, which may be secured thereto by nails such as 38, and which spacing members are adapted to bear against the wall portion 28 to maintain the lower edge of the base board in proper spaced relationship with respect to the wall portion 28. The lower edge of the base board may be maintained from outward movement by the usual molding strip 39 secured to the floor covering 27 by nails such as 40 or other suitable means. A space 41 is thus formed between each of the base boards 34 and the corresponding face of the portion 28 of the wall, in which wire cables such as 42. pipes such as 43, orother conduits or members may be extended. It will be apparent that with this construction no restriction of the breathing action of the floor covering results.
In employing the present invention in connection with the composite type of wall, and particularly where a floor and wall not constructed of masonry is employed, a slightly modified form of construction may be used. Such modification is indicated in Fig. 3 in which the wooden floor 45 is supported upon the stringers 46 and provided with the usual wooden covering 47. At the walls the usual studs 48 are provided and secured directly to the fioor 45 at their lower ends. The channelshaped member 2930 shown in Fig. 1 is modified to meet this modified construction by forming it as two separate Z-sectioned members, each of which is formed to provide an inner upwardly extending flange portion 49, a horizontally outwardly extending flange portion 50, and a vertically extending flange portion 51 extending downwardly from the outer edge of the flange portion 50. 'Ijhe mner flange portions 49 may be secured directly to the studs 48 as by nails 52 at the proper distance from the floor. The studding 48 above the flange portions 49 may be provided with any suitable lathing such as 53 to support the plaster 54, which is preferably extended into flush relationship with the outer faces of the flange portions 51 in the same manner as that described in connection with Fig. 1. Wooden or other base boards 55 may be inserted under the flanges 51 and be secured in position thereby by means of screws 56 or other suitable means. Spacer members 57 corresponding to the spacer members 37 described in connection with Fig. 1 are also provided and the lower edge of the base boards are held against outward movement by means of the molding strips 58 secured to the floor covering 47 by nails such as 59, or other suitable means.
The inner flange 49 are preferably formed so as to provide a support for the plaster 54. This may take the form illustrated in I jlg. 4 in which the flange 49 is shown as being provided with a plurality of openings 60. It may also be further increased as illustrated in Fig. 5 where, in addition to the openings 60 the flange 49 is corrugated in a direction perpendicular to its length, thus providing a better support for the plaster thereon.
Instead of employing nails such as 52 for securing these Z-shaped members to the studs 48, the construction as illustrated 1n Flg 6 may be employed, in which case a plurality of bolts such as 61 are extended through the studs 48 and through the adjacent inner flanged portions 49, and the free ends of the bolts provided with nuts such as 62 for drawing the flange portions 49 into firm contact with the studs 61. Other means may also be employed for securing these Z-shaped members to studs, as will be readily apparent.
Various means may also be employed for removably securing the base boards 55 to the Z-sectioned members. One of such means is illustrated in Fig. 7 and comprises a Z-sectioned member of sheet metal secured to the downwardly extending flange portion 51 in reversed position to the main Z-shaped memher. In other words, it comprises a vertically disposed outer flange portion 63 which is secured to the inner face of the flange portion 51 as by welding or the like, and an inwardly extending horizontal flange portion 64 from whose inner edge the downwardly depending flange portion 65 is provided. The flange portion 65 is preferably spaced from the inner face of the flange portion 51 a dlstance equal to the thickness of.the base board 55 that is to be employed. It is also preferable to turn the lower edge of the flange portion 65 inwardly as at 66 so that in inserting the base board in the socket thus formed for its upper edge, the inturned edge 66 will act to guide the base board into place. With this construction there is usually no necessity for further securing the upper edge of the base board 55, but if desired the screws 56 may be employed in addition.
It will be apparent that in actual practice the sheet metal members which I employ for securing the wooden finishing members in position are preferably of much lesser thickness than that shown, their thickness-being exaggerated in the drawing for the purpose of illustrating the invention more clearly. It will also be apparent that the constructions illustrated are subject to various modifications as may be deemed necessary or desirable, depending upon the conditions under which they are employed. It is also to be understood that although I have shown the present invention in the drawings in connection with a base board only, that with the construction disclosed anyone skilled in the art may apply the same in connection with securing door frames, window frames, or other wooden frame members in place upon a wall, and it is to be distinctly understood that I do not limit the present invention solely to its application to base board constructions.
