8 Claims.

The present invention relates generally to wall constructions, and more particularly to an aircooled wall construction which is adapted to be employed as a furnace wall, or the like, and to particular brackets forming parts thereof.

An object of the present invention is to provide a novel air-cooled wall construction which is adapted to be employed as the defining wall of a furnace, or the like, and which increases the life of the flame-confining material.

Another object is to provide a novel air-cooled wall construction which incorporates a monolithic refractory portion anchored to and spaced from a supporting portion.

Another object is to provide a novel aircooled wall construction incorporating a monolithic refractory inner portion in which an air space is provided between the outside of the monolithic portion and a spaced solid support which protects supporting brackets disposed therein through cooling the same and which provides preheated combustion air.

Another object is to provide a novel anchor bracket for a monolithic wall which is constructed to support members adapted to serve as an abutmerit for the outer surface of the monolithic wall.

Another object is to provide a novel bracket which is adapted to support a segment of a monolithic wall and to anchor the monolithic segment against movement from its initial substantially vertical plane, and which further supports a structural member adapted to prevent movement of the monolithic segment in the other direction from that prevented by the anchoring function of the bracket.

Another object is to provide a novel air-cooled refractory wall construction which finds manifold adaptations in enclosing furnaces, and the like, of single or battery type.

Other objects are to provide a novel air-cooled wall construction of the monolithic refractory material type in which an air cushion of static or moving air is provided between the inner monolithic refractory wall portion and an outer solid wall, or between two spaced monolithic refractory walls, to achieve a minimum of heat loss to the exterior, and to protect the outer wall and supporting brackets from excessive heat, which is of sturdy and long lasting construction, which is readily fabricated in its manifold adaptatio'ns, and which is relatively economical to install.

Referring to the drawings more particularly by reference numerals and specifically considering Figs. 10 through 12, 20 indicates generally an aircooled wall construction fabricated in accordance with the teachings of the present invention. Broadly, the preferred embodiment of the aircooled wall construction 29 of Figs. 10 through 12 includes an exterior wall 22, combination structural member positioning and supporting and monolithic wall section anchoring and supporting brackets 24 (Figs. 1 through 4), combination structural member positioning and supporting and monolithic wall anchoring brackets 26 (Figs. through 7), a monolithic refractory wall 28, inner monolithic refractory wall anchor tiles 35 (Figs. 8-9), structural members 32, and corrugated backing sheets 34. An air space 35 is thus defined by the wall 22 and the sheets as which may contain static or circulated air, or the like.

The exterior wall 22 is formed of spaced structural steel I beams 36 between which are bricks 38. At selected positions, steel structural channel members 48 are bolted or otherwise connected to the inner flanges of the I beams 36. Exteriorly disposed reinforcing steel T beams 42 may be used to assist in maintaining bricks 33 in place.

A bracket 25 is connected by bolt assemblies it to each I beam 36 against the web of the channel members ii}, the same bolt assemblies 34 also maintaining the channel members 49 in place. The bracket 24 is of the configuration clearly shown in the drawings (Figs. 1 through 4), and includes a double flange 56 having opposed notches 43. A vertical web 50 is formed integral with the flange 46, and is reinforced by a bead 52 extending around three sides thereof. A channelshaped opening 54 is formed in the web 513. A platform 55 extends outwardly from the vertical portion of the bead 52, the outline of the platform being clearly shown in Fig. 1. A platform supporting web 58 is disposed beneath the platform 56 and in the plane of the web 59. A refractory member or tile receiving post 68 is mounted on the platform 56. A web 62 is disposed on the platform 56 between the Vertical portion of the bead 52 and the post 60.

The bracket 26, which is employed with the bracket 24 to form the supporting and anchoring elements of the present wall construction 20, includes a double flange 64 having opposed notches 56 (Figs. 5 through 7). A vertical web 68 formed integral with the flange 64 extends outwardly therefrom and is reinforced by a bead it. A channel-shaped opening 12 of substantially the same shape as the channel-shaped opening 54 of the bracket 24 is formed in the web 68. An upwardly extending post 14 is supported at the free end of a bead extension 75. Each bracket 26 is supported from the inner leg of an I beam 36 by bolt assemblies 78 (Figs. and 12).

The refractory anchor tiles 3!] may be of any configuration within wide limits, but a preferred form is shown in the drawings. The tile 33 is more particularly described in my copending application, Serial No. 678,347, filed June 21, 1946, now abandoned. At its reduced end, the tile 39 includes a vertical opening 89 and a connecting groove 82. In Figs. 14 and is shown a bracket 22' which is the same as the bracket 24 in all details except attaching flange. The bracket 2 includes a circular flange 84 having a central aperture 85. Below the circular flange 84 is a heel flange 88 wh ch is flush with the circular flange 84 and wh ch is connected with the latter by a web 92. As is shown in Fig. 18, the bracket 24' is secured to a supporting wall, such as a brick wall 92, by a single bolt assembly 9 3.

In Figs. 16 and 17 there is shown a bracket 26' which is of the same form as the bracket 26 with the exception of the attaching flange. The bracket 26 includes a circular flange having an aperture 96 therethrough and a heel flange 91 in the same plane as the circular flange 95 and connected thereto by a web 98. The same reference numerals employed in respect to the brackets 24 and 26 are applied to the brackets 24 and 26' except for the foregoing flange constructions. As is shown in Fig. 18, the bracket 26' is connected. to the wall 92 by a single bolt assemblage I 00.

In fabricating the present novel wall construction 20, the I beams 36 of the wall 22 are duly positioned and the channel members at bolted thereto. The brackets 2 are bolted to the web of the channels 40 and to the inner leg of the I beams 36 by the bolt assemblies 44, and the brackets 26 are secured to the inner legs of the I beams 35 by the bolt assemblages 18. Thereupon, the bricks 38 are placed between the webs of the I beams 36 which may be reinforced by the T members 42. The brackets 24 and 26 are disposed in spaced horizontal rows. Structural members 32 are inserted through the channel openings 5d and 72 thereof, respectively, for support thereby. In the drawing, angle irons are shown, though the cross section of the structural members 32 may. vary as desired. It is preferable to use structural members 32 having at least one fiat surface against which the cor rugated metal sheets 34 are disposed. The sheets 34 are located exteriorly of the structural members 32 after the latter are installed, thus defining the air space 35 between the sheets 3t and the wall 22.

The monolithic refractory wall 23 is then built up against the sheets 3 as a backing. The refractory wall 28 is formed from plastic refractory material. As the level of the plastic refractory material from which the wall 28 is formed reaches a row of brackets, the refractory tiles til are disposed on the respective posts, the vertical opening 80 and the slot 82 of the tile 39 surrounding the post 63 and the rib 62 of the bracket 24 and the post M and the bead extension 16 of the bracket 26, as the case may be. After the wall 28 is completed, contraction lines I02 are marked in the outer surface to define monolithic wall segments to be supported by the brackets 2 and their associated tiles 32.

It is manifest that in fabricating the wall construction 26, shown in Fig. 18, the steps are the same as in the fabrication of the wall construction 29, except for the initial building of the brick wall 92 and the provision of openings to receive the long bolts of the bolt assemblies 95. In Fig. 13, insulation I84 is shown disposed in the plane of the structural members 32, which are shown as channel members.

The present wall construction it finds numerous adaptations in addition to those particularly disclosed herein. For example, the present Wall construction 29 may be employed to advantage in the formation of the defining walls for a battery of furnaces, and the like. When the wall construction 28 is adapted to define a battery of furnaces, or the like, a central vertical structural member, such as an I beam, will carry two vertical rows of brackets 24 and 2s disposed at to each other. A plurality of such structural.

members with the double row of brackets 24 and 23 will replace the wall 22, and there will be a refractory wall 28, or the like, on each side of the supporting structural members.

The brackets 24 and 26 and the modifications thereof are preferably cast as integral units, a1- though they may be fabricated.

It is apparent that there have been provided a novel wall construction and novel brackets forming parts thereof adapted to fulfill the objects and advantages sought therefor.

The foregoing description and the accompanying drawings have been given by way of illustration and example. It is to be understood that changes in form, substitution of equivalent elements, and rearrangement of parts that will be manifest to those skilled in the art are contemplated as within the scope of the present invention, which is limited only by the claims which follow.
