13 Claims. 1

The present invention relates to a wall support, and more particularly for a tile-supporting construction by which tiles of a refractory or the like nature may be Supported on a wall framework.

It is an object of this invention to provide a tile support construction wherein there are brackets spaced at intervals and runners removably mounted thereon, with locking means to prevent accidental removal of the runners from the brackets. More particularly, it is an object to provide against such removal of the brackets under the influence of expansion and contraction forces acting upon the wall.

It is a further object to provide such locking means that may be readily operated when the assembly is set up, with a minimum of difficulty and. with a minimum of parts, yet with assurance that the wall will be properly constructed regardless of the quality of workmanship.

A specific object is to provide a runner and runner supporting bracket that have rigid interlocking elements engaged when the parts are. in operating position, so that the wall must be constructed in proper manner, and so that no parts can be omitted by accident or design.

In the drawings:

Fig. 1 is a vertical section of a wall employing the present construction;

Fig. 2 is a horizontal section taken on the line 22 at the upper part of Fig. 1;

Fig. 3 is a horizontal section taken on the line 3-3 at the upper part of Fig. 1;

Fig. 4 is a vertical section through one of the hangers or brackets, taken on the line 44 at the top of Fig. 1;

Fig. 5 is a front elevation of one of the runners;

Fig. 9 is a side elevation of the bracket;

Fig. 10 is a front elevation of the bracket; and

Fig. 11 is a side elevation of a runner supported intermediate its ends upon a single bracket.

This apparatus is designed to be used on a wall framework of any suitable kind. There is here shown a steel framework consisting of vertical beams 20 with transverse horizontal beams 2| and 22 secured thereto at spaced heights. It will be understood that the horizontal beams and vertical beams are in such number as to provide a framework over the entire wall. This framework may be vertical or horizontal, or may be arched, or disposed in any desired position.

.the only combination of parts.

In other words, the wall may be a side wall, a ceiling, a floor, or some angular or arched wall.

At suitable points in the framework, hangers or brackets are provided. They are horizontally spaced the distance between centers of the tiles, as shown in Fig. 2, and are vertically spaced the distance between the horizontal beams; In the present illustration, the hangers. 24 and 25, holtedto the cross beam 2|, typify the columnar spacing of the hangers, and the hanger 26, similarly boltedto the cross beam 22, illustrates the spacing within the columns. These hangers are shown in greater detail in Figs. 8-10. They are identical in principle of construction. Each includes a back plate 28, notched at 29 and 30 for receiving the attaching bolts 3! by which the hanger is secured to the beams. The notches provide for some lateral adjustment to accommodate irregularities of mounting.

Projecting forwardly from the back plate 28 is a web 33.' This web is of greater vertical extent at itsouter edge than at the back plate 28, and may be reenforced with ribs. It has at its forward edge an operating face 34 from which project a pair of spaced

hooks

35 and 36 and a pair of

lugs

31 and 38. It will be seen that the hooks 35 and at are spaced apart approximately the same distance as are the two lugs 31 and38'. Between the lowermost parts of the

hooks

35 and 36 is a locking dog 39. This slopes downwardly and outwardly, as shown particularly in Fig. 9, and has a transverse bottom ledge 40.

Tile holding runners are adapted to be hung in the hangers. Three such runners are shown in Fig. 1 at 42, s3 and hhalthough, as will appear, the particular arrangement of Fig. 1 is not Similar runners will be connected with the other bracket series, such as that of bracket 26.

These runners are shown more in detail in Figs. 5 and 6. A somewhat shorter one is shown at in Fig. '7.

Each runner is in the general form of a beam, having a web 1?. The back edge of the web 41 receives a plurality of supporting pins 43 spaced therealong. These pins project outwardly from the opposite sides of the web, so as to be disposed transversely thereof. They are adapted to engage in the two

hooks

35 and 36 of the hanger brackets while the web 4'! is disposed between the two hooks. The back edge of the web 41 is also provided with a series of notches 49 that preferably slope inwardly and downwardly, as shown in Fig. l and Fig. 7 to provide a transverse ledge 50. .These notches are so located 3 along the web 41 that one will receive the looking dog 39 of a bracket when any pair of the pins 45 is engaged in the hooks 35 and 3B of that bracket.

The webs 4'! may be provided with a transverse reenforcing rib 5|. From the front of this reenforcing portion, a plurality of tile holding elements, generally indicated at 53, project. Each comprises a spacer 54 extending outwardly in the plane of the web 41 and bearing a transverse holding plate 55 at its outer end. Thus, the tile holding elements are T-shaped in cross section. They are adapted to receive the T- slots in the tiles, as will appear.

The lowermost tile holding element on each of the runners is preferably provided with a bottom shelf 51 to give vertical support to the several tiles mounted upon the particular runner. When the lowermost set of pins 48 is engaged in the

hooks

35 and 36, the bottom of the runner extends down approximately as far as the

lugs

31 and 38. The bottom of the web 41 is cut away to provide a recess 58. The top of each runner is haped at 59 to fit between the

lugs

31 and 38, and in the recess 58 of the next runner, thereby to be secured against displacement.

Construction of the wall The framework, consisting of the

several beams

20, 2|, 22, etc., is ordinarily of a permanent construction. The description thus far and to follow treats a vertical wall section, although it will be understood that this not a limitation.

It will be assumed that the hanger 26 is the start of the construction. This hanger will be bolted onto its cross beam 22 in proper alignment. Thereupon, the runner 43 will have its lowermost pins 48 disposed between the two

hooks

35 and 36 of this hanger 26. In this operation, the depending part of the web 41 below the bottom locking notch 49 will slide downwardly over the locking lug 39 of the hanger. This will require a'rocking movement of the upper end of the runner 43 from a position counterclockwise of that shown, to the position illustrated wherein the notch 49 is engaged over the lug, so that the two horizontal ledges 4D. and 50 are brought together to prevent vertical movement of the runner when it is in the vertical position shown.

Thereafter the next upper hanger 25 can be installed. It will be applied to the beam 2| in a manner to slip its

lower lugs

31 and 38 over the upper end 59 of the runner 43. Then it will be bolted into position on the beam. It will be seen that it prevents backward or lateral movement of the top of the runner that would disengage it from the two lugs. Further clockwise pivoting of the bottom of the runner may be restricted by the engagement of the back face of the web 41 at the bottom against the operating base of the lower hanger 26.

The next higher runner 42 may then be secured to the hanger 25 in a similar manner. It disposes its lower recess around the top 59 of the runner 43, and thereby prevents clockwise rocking of the top end of the runner 43. Thus this runner is completely secured in position, and neither of its ends may become disengaged.

The several tiles may be installed on the runners in the manner known in the art, as illustrated by the applicants copending application, Serial No. 603,201, filed July 4, 1945. Suffice it herein to say that the bottom tile 60 is inserted'over the lowermost tile receiving element 54. All of the tiles have T-shaped slots to engage over the T-shaped tile holding elements. The various tile holding elements are vertically spaced suificiently far to permit the insertion of tiles between them. The bottom tile 60 is cut away to fit over the shelf 51. The tiles have tongue and groove interlocks, both on their sides and on their tops and bottoms. The lowermost tile 60 also preferably has a ledge interlock with the top tile of the lower course. The higher tiles, 6|, 62, etc., are laid over the bottom one- The several tiles are united by cement.

The top tile 63 of this course cannot engageover a tile holding element and must be cemented into place, against adjacent tiles, and. particularly the tile 10 of the course above.

Where the walls are in refractory furnacesandthe like, any qualities of expansion becomea problem. Heretofore, there has been a tendency for the forces of expansion to disconnect therunners from the hangers and thereby to permit the walls to come apart. The interlock. members 39 and '49, between the brackets and. the runners here prevent disconnection of thepins 48 from'the hooks 35 and 36. Also, the upper ends of the runners are interlocked by the

lugs

31 and 38 and their interfit with the depending ends of the next higher runners. The top part 59 of each runner may move vertically to accommodate expansion and contraction- This, is permitted by the fact that the projection 59 does not extend to the top of the recess: 48, under normal temperature conditions, but rather occupies a medial position therein suffi-- cient to permit some relative vertical movement by expansion or contraction.

It will be seen that the brackets and runners are installed with a minimum number of parts. It is impossible to build the Wall Without con-- structing it properly with the several locking means and attaching means properly engaged. This overcomes oversight of workmanship that otherwise might cause a wall to come apart after it is completed. The several parts may be made of simple castings by the present construction, thus reducing the expense. As already noted, in the copending application, the provision of hangers that are separate from the runners permitsmodification of the spacing between the tiles and the steel framework by the simple substitution of different hangers, without changing the runners which may be standard all the way through. The runner of Fig. 7, however, illustrates a type of runner for fill-in purposes where the. spacing between hangers is offsize.

It is not necessary that the wall be constructed precisely as shown in.Fig..l. The provision of an entire series of pins 48 permits a runner to be engaged intermediate its ends with a particular hanger. It. may be seen from Fig. 11 that the engagement of a runner midway of its ends with a particular hanger provides a secure arrangement. In Fig. 11 a runner is shown supported on a bracket intermediate the ends of the former. A selected pair of intermediate pins 48 rests in the spaced hooks 35 and 36 of the bracket 25 and a portion of the web 41 of the. runner extends between the spaced lugs 31 and 38.

It will equally be understood how the construction would be made for horizontal or angular or curved walls. a 7
