HENRY WARD PET'TY QTTOPIl/EY snsaesi M AEGNRY WALL .l-(DHWT AND C(IWEF. THEEEFQ'R Henry Ward Petty, 39 E. Main St., Meorestovrn, Nul Filed Get. 7, 1957, Ser. No. 658,719 7 Claims. (*l. Sit-212) This invention relates generally to means for constructing joints between adjoining sections of building Walls, and more particularly to improved means for covering such joints and thereby enhancing the appearance of the wall.

A principal object of the present invention is to provide a frame structure unit adapted for use in both vertically and horizontally extending joints and which, While allowing some movement of the wall sections in a direction parallel to the wall, effectively secures the wall sections against movement laterally relative to one another.

Another principal object of the present invention is to provide such a frame structure unit which may be conveniently utilized to construct a masonry wall in a series of attractively arranged panels, whereby shrinkage cracks are controlled to a point where the exposed masonry may present an attractive appearance, thus eliminating the necessity for plastering and painting the wall.

Other objects and advantages of the present invention will appear more fully hereinafter, it being understood that the present invention consists substantially in the combination, construction, location and relative arrangement of parts, as more fully described hereinafter, as shown in the accompanying drawings and as finally pointed out in the appended claims.

In the accompanying drawings:

FIGURE 1 is a perspective view of a masonry wall illustrating the use of an exemplary frame structure unit constructed in accordance with and embodying the principles of the present invention.

FIGURE 2 is an elevation of a masonry wall having door and other openings and illustrating the use of the frame structure units of the present invention in vertically extending joints between adjoining wall sections.

FIGURE 3 is an enlarged section on line 3-3 of FIGURE 1, the brick facing of the wall being omitted.

FIGURE 4 is an enlarged vertical section on line 44 of FIGURE 2.

FIGURE 5 is an enlarged partial transverse section of the frame structure unit of the present invention.

FIGURE 6 is an enlarged horizontal section on line 66 of FIGURE 2.

FIGURE 7 is an enlarged vertical section on line 7--7 of FIGURE 8.

FIGURE 8 is a perspective view illustrating the use of the frame structure units of the present invention in a masonry wall of uniform thickness and partially faced with brick on one side.

Referring to the drawings, and particularly to FIG- URES l, 3, 5 and 7, the exemplary structure constructed in accordance with and embodying the principles of the present invention includes a pair of elongated rigid members lit-Ml of uniform T-shape in transverse section. These members l0ltl are disposed in laterally spaced parallel relation, the head or flange parts, designated lllll, being disposed respectively in laterally spaced parallel planes, and the stem or web parts, designated 12-42, being disposed in coplanar relation.

For tying the T-shaped members Ill-lit} together, the structure is provided with a plurality of elongated rigid members that are located at convenient intervals along the length of the structure. Each tie member includes a pair of

fiat bar parts

13 and 14 that conjointly bridge corresponding portions of the members llll10. The bars 13 and 1d are disposed in longitudinal continuation of one another with meeting end portions in. side abutting overlapping relation and secured together by a bolt 15 that is projected through elongated openings or slots ll6-l6 formed respectively in the

members

13 and 14, and which is drawn tight through the medium of a wing nut 17. Each opposite terminal portion of the tie member is disposed in side abutting overlapping relation to the web 12 of the associated T-shaped member 10, being secured thereto by a rivet 18.

Each of the confronting surface areas of the overlapping meeting ends of the

tie bars

13 and 14 is provided with a series of serrations that extend transversely there of, the serrations of the member 13, designated 19, and the serrations of the member 14, designated 20, being closely internested and operative conjointly with the bolt 15 for securing the tie member against axial shifting movement of the

bars

13 and 14 relative to one another. Each end of the

tie bars

13 and 14 which engages the web 12 of a T-shaped member lll is also provided with a series of serrations that extend transversely thereof. The serrations of the member 13, designated 27, and the serrations of the member 14, designated 28, closely internest with the serrations 21 on the web 12 of the T-shaped member 19 and thereby, when secured by the rivets l8, prevent shifting movement of the

tie bars

13 and 14 relative to the web 12.

Referring particularly to FIGURES 7 and 8, in lieu of the sectional tie member illustrated in FIGURES l, 3 and 5, the structure may be provided with tie members each consisting of a single bar 24 essentially the same in every respect to the tie member bar 13 described hereinbefore. In this case the slotted end portion of the bar 24 is connected directly to the web of the associated effective length that affords a suitable clear distance between the flanges llll of the T-shaped members Illll), depending upon the thickness of the wall desired. Then the units are erected at selected locations where construction joints are desired, being temporarily supported in any suitable manner. Now a section of the masonry wall designated B, is built up between each successive pair of the units A.

Referring particularly to FIGURES 3 and 6, on each side of each unit A the associated vertically extending end portion of the masonry wall section, designated C, extends into the unit and nests snugly between the flanges ll1ll, and close up to the webs l212, of the T-shaped members l-llh in consequence of which the webs l212 of the T-shaped members and the tie members are disposed within the vertically extending break between adjoining wall sections BB, which break, designated D, is covered and completely concealed from view by the flanges 11-11 respectively on opposite sides of the wall, as shown.

The frame structure of the present invention may be utilized with equal facility to form horizontally extending construction joints. A masonry wall section is built up to a desired height. Then a unit of the frame structure, adjusted to the thickness of the wall, is fitted over the top of the wall section. Now a second wall section is built upon the first frame structure unit and capped with a second frame structure unit, etc., until the desired spanner height is attained. The webs ll212 of the T-shaped members and the tie members are disposed within the horizontally extending break between adjoining wall section, which break is covered and completely concealed from view by the flanges Ill-11 respectively on opposite sides of the wall, in the same manner as described hereinbefcre in the case of vertically extending breaks in masonry walls.

If desired, both vertically and horizontally extending frame structure units may be incorporated in the same wall to'advantage, whereby to subdivide the wall into rectangular panels arranged in an attractive pattern.

It will be appreciated that wall cracks that normally develop in masonry walls due to shrinkage of the material and expansion and contraction due to temperature changes are effectively controlled by the liberal use of the frame structure units of the present invention, in consequence of which the appearance of the masonry is enhanced, and it can be exposed to view without being plastered, painted or otherwise dressed, which of course makes for economy of construction.

Wherever a frame structure unit of the present invention is utilized, the ends of walls built into opposite sides thereof are free to shift somewhat relative to the unit in a direction parallel to the wall, but the unit is operative to secure said wall ends against becoming misaligned by shifting laterally relative to one another. Thus, in addition to affording a wall that is more attractive and economical to construct, these frame structure units afford a wall that is effectively reinforced against bulging. Certain other advantages are inherent in the frame structure units of the present invention.

For example, such units may be used to advantage over the'tops and/or bottoms of door and other openings in the wall, as best shown in FlGURE 2, to prevent the development of cracks that normally appear in these areas. Such units may be made to follow irregular wall contours. For example, as best shown in FIGURES 2 and 4, where a wall, otherwise uniform in thickness, is provided with facing or any other outward projection on one side thereof, a section of the web of the T-shaped member on the side of the wall provided with the facing or projection may be cut out, as at 25, and the portion of the flange opposite the cut out, designated in, may then be fitted to the irregular contour. Then the tie members above and below the top of the cut out are adjusted to the different wall thicknesses.

While the frame structure units of the present invention preferably are made of suitable metals, such as aluminum, bronze, brass, steel, etc., it will be understood that other materials, for example, plastic materials, may be found suitable, depending upon the particular application.

It will be understood, of course, that the present invention is susceptible to various changes and modifications which may be made from time to time without departing from the real spirit or general principles thereof, and accordingly it is intended to claim the same broadly, as well as specifically, as indicated by the appended claims.
