SEALED FRAME CROSS JOINT Filed April 16, 1963 M lie/1f United States Patent (i).n
3,223,209 SEALED FRAME CROSS JOINT Stephen A. E. Skromeda, Torrance, Calif., assigner to Pacific Curtainwall, Inc., Long Beach, Calif., a corporation of California Filed Apr. 16, 1963, Ser. No. 273,476 2 Claims. (Cl. 1S936) The present invention relates to seals, and more particularly to a novel means of sealing the joints of interlocking structural members.
Although the seal of the present invention to be hereinafter described is highly suitable for a variety of interlocking joints, the example selected for illustration of one preferred embodiment relates to structural frame members of curtain walls and like types of building structures.
In such construction, the panels or windows that cover most of the area of the exterior Walls of such buildings are supported by vertically-disposed extruded metal tubes and horizontally-disposed extruded metal members interlocking therewith.
In the trade, the vertical tubes are often referred to as mullions; the horizontal members being called muntins or bars.
The problem of sealing the joints of the interlocking vertical and horizontal members is difficult because of moisture intrusion, wind stresses, expansion and contraction strain, etc., all of which are constantly imposed on building Walls. Thus far no sealing means has been found that solves the sealing problem to complete satisfaction.
It is an object of the present invention to provide a means for sealing the joints of interlocking wall frame members which sealed joint is impervious to moisture and Weather and is unaffected by relative movement of the members.
It is yanother object of the present invention to provide a means of sealing the joints of interlocking members that closely adheres to the interlocked surfaces but is suciently flexible between the adhering surfaces that no rupture, separation or peel-away of the seal from the joint is possible during relative movement between the members Other objects will become apparent as the specification proceeds.
I u the drawings:
FIGURE 1 is a perspective view of a typical joint of interlocked vertical and horizontal members.
FIGURE 2 is a diagrammatic sectional View of the interlocked joint taken along lines 2 2 of FIGURE l.
FIGURE 3 is a diagrammatic cross-sectional view of the interlocked joint taken along lines 3 3 of FIGURE 2.
FIGURE 4 is a perspective view of a typical block of sealant material in its normal state.
FIGURE 5 is a perspective view of the sealant material shown in FIGURE 4 in its compressed state.
In FIGURE 1 a typical section of a vertical mullion or tube 5 is shown. The shape of the extruded metal tube in cross-section, to be described below, is typical along the entire length of the tube and comprises an exterior box section 6 joined by an integral web 7 to the rear or interior wall 8 of the tube 5, the forward end of web 7 being joined to the rear side 9 of box section 6.
The recess 10 defined on each side of the web 7 encloses the side edge of the panel or window (not shown) to be supported therein.
The opening 11 in the exterior box section 6 is finally closed with a cover or cap (not shown) that snaps in place between grooves 12 provided on each side of the opening 11.
The rear side 9 of the box section 5, on each side of the web 7 is provided with integral shouldered anges 13 that define U-shaped seal channels 14 between the lianges 13 and rear side 9 of section 5.
3,223,2tl9 Patented Dee. 14, 1955' ICC A horizontal bar 15 is joined in interlocking relationship with the Vertical tube 5, being disposed normal to each other with one end of bar 15 extending into recess 10 of vertical tube 5 forming a joint 16 at the intersection, which joint 16 must be sealed.
The horizontal member 15 preferably is extruded of metal and has a generally T-shaped cross-section as best shown in FIGURE 2, being positioned normally with respect to thek vertical tube 5 so that the widest cross-bar 17 of the T-section is disposed 'adjacent to the exterior of the wall.
The upper side of web 18 of the horizontal lmember 15, that extends between the cross-bar 17 and a narrower cross-bar 19, forms a recess to support the bottom edge of a Wall panel or window (not shown); the other side forming a recess for the upper edge of the wall panel below (also not shown).
Sealing strips are interposed between the edges of the window panels or window panels and the adjacent surfaces of the vertical tubes and horizontal members in the conventional manner. This construction is well developed and familiar to those :skilled in the art and therefore the sealing strips and panels have been omitted herein as they form no part of the invention described herein'.
A slot 21 is cut through the Wall of flange 13 on the rear side 9 of box section 5 of the tube, wide enough to accommodate the full width of the cross-bar 17 of horizontal member 15; a similar but narrower slot 22 also being cut through the' wall of flange 23 provided on the in-y side face of the rear wall 8 to accommodate cross-bar 19 at the opposite end of web 18, as best shown in FIG- URE 2.
To join the members, the end of the horizontal member 15 is positioned normal to vertical tube 5 and extended into the recess 10 bounded on three sides by the rear side 9 of the box section 6, web 7, and rear wall 8 of the vertical tube 5. By holding the tolerances fairly close on the dimensions of the slots 13 and 22, a neat-appearing joint 16 can be made. However, a reasonable clearance should be allowed laround the slots .so that the vertical and horizontal members can be assembled with minimum etort.
To seal the exterior joint 16 according to the present invention, there is required a block of a packing material or sealant that can be compressed and attened to `a fraction of its normal thickness, which, after a short period of time, will return to its original or normal thickness. A block of such material is compressed to a thin enough section to be inserted into the channel 14. The packing material is cut into blocks that are sutliciently long to bridge the slot 21 and extend an appreciable distance along the channel 14 on each end of the slot 21.
The horizontal member 15 can be inserted easily into the recess 10 provided in vertical tube 5 while the packing material 25 is in the compressed or flattened state in the channel 14.
To prevent the sealant material 25 from creeping out of channel 14 around the recessed end of horizontal member 15, a continuous groove 26 is formed in the inside face of flange 13, exteriorly of the sealant material, into which cylindrical rods 26 can be installed on each side of cross bar 17 as shown in broken line in the partial phantom view of FIGURE 2, the rods 26 extending parallel with the recess behind the block of packing material 25 to act as dams or barriers preventing creep-out of the sealant. Between each rod 26 installation of cross bar 17 prevents the packing material 25 from creeping out of channel 14 between rods 26.
While many possible packing materials and sealants may come to the minds of skilled artisans, a sealant that is preferred for use in forming the sealed joints of the present invention is available on the market, known by its trademark Compriban-d. The material consists of a body of cohesive material characterized by an elastic plastic foam structure defined by thin Walls around open pores impregnated or coated with bitumen. The bitumen is solid and non-tacky at room temperature. A detailed description and method of making it in several forms is disclosed in U.S. Patent No. 2,964,424, dated December 13, 1960, for Bitumen-Impregnated-Foam Packing Material by Laban Mast.
-In appearance, a block of uncompressed Compriband resembles the drawing of FIGURE 4. In its compressed or flattened state Compriband looks somewhat like the drawing of FIGURE 5.
Compressed Compriband resumes its original or normal dimensions very slowly; something in the order of -20 minutes depending upon the tackiness of the bitumen.
However, other sealant material such as foam rubber, etc., impregnated with glue or partially cured resin, may be used if desired.
As part of the sealant expands through the slot 21 in flange 13 of channel 14 in vertical member 5 to resume its normal dimensions, the material will exert sufiicient pressure against the adjacent surface of cross-bar 17 of horizontal member 15 to closely adhere thereto.
It should be here mentioned that it is possible to insert the sealant into the channel 14, with the use of certain tools, after the members have been joined t-ogether. However, the insertion is more difficult and is not recommended.
The sealed joint 16 made according to the foregoing teaching is imprevious to moisture and other elemental media, unaffected by oxidation, stresses, `and the expan- 'sion and contraction strains that are constantly imposed thereupon, and is substantially permanent due to its resistance against weather.
' Numerous other applications of the present invention will be apparent to those skilled in the art, such as in sealing auto body joints, packing or shipping containers, meter boxes, engine and motor housings, etc., to mention but a few. All such uses of the joint seal described above are deemed to fall within the scope of the present invention.
What is claimed is:
1. A sealed joint in a wall structure comprising:
(a) an extruded vertical member formed of Van exteriorly disposed tubular box section joined by an integral web to a rear wall, recesses being defined on each side of said web between said box section and rear wall to retain the side edges of wall panels to be supported therein,
