Patent No. 3,376,679, dated Apr. 9, 1968. Divided and this application Nov. 17, 1967, Ser. No. 684,576
Int. Cl. 1323p 17/00; E04b 2/00 US. Cl. 29-155 2 Claims ABSTRACT OF THE DISCLOSURE The present invention comprises the method of forming a triangular channel strip of resilient material having a prescribed normal gap at the open apex thereof smaller than the spring-back gap which could be obtained by normal break-forming so that the strip could be used as a lock strip with the gap edges resiliently pressing on opposite sides of a double thickness of sheet material over which they are mounted, as in the case of such lock strip holding the channel flanges at the two edges of adjacent sheet panels joined together in sealing relation, the double thickness of this sheet material being less than said springback gap. The method includes a step for reducing the spring-back gap, by bending the bottom of the channel outwardly by pressing a plate die against the middle of said bottom, the plate having a maximum thickness of said double thickness of sheet material, whereby the required normal gap which is less than said double thickness after spring-back,'may be obtained.
This is a division of pending application Ser. No. 475,305, filed July 12, 1965, for Sheet Panel Wall Assembly, which issued on Apr. 9, 1968, as Pat. No. 3,376,679, and the invention relates to walls of sheet panels and joints of the type which can be manually assembled on the job to provide a rigid support frame for the wall being constructed, axially of said joints, without requiring any tools, bolts, nuts, screws or any other attaching means, and without puncturing any parts of the panel joint as well as a method of making clip strips for said joints.
The object of the present invention is to provide a method of making a triangular channel strip with a gap between the outer edges of the sides of the channel which is less than the spring-back of said strip material after the process of break-forming the base angles of the channel.
Other and more specific objects will become apparent in the following detailed description of a preferred form of the invention, as illustrated in the accompanying drawing, wherein:
FIG. 1 is a top plan view of a wall portion made of panels showing an in-line joint and a corner joint between adjacent panels, in accordance with the present invention,
FIG. 2 is a front elevational view of said wall portion,
FIG. 3 is a rear view of said wall portion taken on the line 3-3 of FIG. 1,
FIG. 4 is a vertical sectional view of said wall portion taken on the line 44 of FIG. 2,
FIG. 5 is a vertical sectional view taken on the line 55 in FIG. 1,
FIG. 6 is a vertical sectional view taken on the line 66 in FIG. 3,
FIG. 7 illustrates the break forming method of making a triangle-formed clip strip with a channel opening, which is less than the spring-back of the sides obtained in their break-forming process, and
FIG. 8 shows the shape said triangle-formed channel 3,462,819 Patented Aug. 26, 1969 takes after the bottom of the triangle has been flattened by the edge of a pressure plate passed through the gap between the sides of the triangle.
The panels used in the present invention may have any configuration between their side edges 10, but these edges have identically formed channel flanges 12 which are clipped together by means of the closely spaced outer edges 14 of the opposite sides 16 of a channel strip to form a sealed joint between adjacent panels.
The drawing illustrates an assembly of a joint 18 between aligned panels in the same plane and a joint 20 between corner panels joined perpendicularly to each other. However, it is to be understood that similarly formed channel strips may be made for corner panels joined at other angles to each other.
The triangle-formed channel strip 22 is adapted for sliding endwise during assembly over the channel flanges 12 of the adjacent aligned panels to firmly clip the flanges together along their entire length, by a pressure line contact x of the outer edge of each side of the channel strip against the inside of the corresponding flange 12. The outer edges of the channel flanges 12 extend into the inner bottom corners of the channel strip 22 to keep the channel flanges 12 of the adjacent panels aligned and to keep the clip at the outer edges of the channel strip sides 16 from sliding outwardly of the flanges 12.
A second channel strip 24 may be fixed in the bottom of the channel of the channel strip 22 and have its sides extend around the outer edges of flanges 12 to provide a sliding fit thereover during assembly, maintaining only substantially six points of pressure line contacts x between channel strip assembly and the channel flanges 12 in the joint, thus reducing the sliding friction to a minimum in said sliding fit, while maintaining substantially continuous sealing line contacts at these points. The corners at the ends of the channel strips 22 and 24 at these contact points may be flared out to facilitate starting the sliding operation of the channel strip assembly over the ends of the channel flanges 12 at each joint, as shown e.g. at the bottom of the sides 16 of the lock strip portion shown in FIG. 5. Obviously, the channel strip assembly provides a strong reenforcement to the wall assembly so that no additional framework is normally required in a wall assembly of these panels, even if the sheet material used for forming the panels and the channel strips is of very small gage. The wall is easily assembled without the use of any screws, bolts, nuts or other attachments and without puncturing or deforming any parts of the assembly, so that the wall may be just as easily and quickly disassembled and moved to new locations whenever desired, without detriment to its good sealing characteristics at the joints.
Similar channel strip assemblies are used for assembling corner joints as for the in-line panel joints described above. A right angle joint 20 is shown in the drawing for illustration. The sides 16 and the corners at the bottom of the channel strip 22 and the sides of the inner channel strip 24' are identically formed to those in the channel strip assembly for the in-line joint 18. The bottoms of channel strips 22' and 24', however, are separated by extending the bottom of strip 24' into angular space to form a hollow post of comparatively greater strength to form a corner post assembly, which is slid over the ends of the flanges 12 of the adjacent corner panels similarly to the assembly of the in-line joint, and has similar six points of pressure line contacts to keep the edges of corner panels in proper angular alignment and to provide as good a sealing joint.
The sheet material used for the panels as well as the channel strips may be steel or any other material having suitable resilience to provide sufficiently strong clipping 3 means for the joints as well as frame supports for the wall.
In forming the triangle-formed channel strip, where a sufiiciently small gap between the outer edges of the sides 16 cannot be formed by a break-forming machine because the spring-back of the sides is more than the said gap, the strip may be break-formed into a W crosssection as shown in FIG. 7, with the angles between the inner and outer legs 26 and 28 of the W substantially equal to the required base angles (about 70 in the present case) of the triangle form that will produce the desired gap, when the inner legs are straightened out to form the base of said triangle form. Then, by pressing down on the ridge formed by the inner legs 26 until it is substantially flat, by means of the edge of a flat plate 30, of a thickness not greater than the required gap, the proper gap may be obtained. This method may also be used for controlling the size of gaps in triangular grooves formed in sheet panels such as disclosed in my prior patent application S.N. 194,339, filed May 14, 1962, for Panel and Joint, which issued on Mar. 22, 1966, as Patent No. 3,241,284, where a minimum gap is desired merely to provide enough clearance to allow for heat expansion of the adjacent faces of the panel without buckling.
Many obvious modifications in the form and relations of parts may be made without departing from the spirit and scope of the present invention as defined in the appended claims.
What is claimed is:
1. A method of forming a triangular channel strip of resilient sheet material normally having a desirably small gap between the outer edges of the converging sides of the channel which gap is less than the spring-back of said sides from a closed gap break-form position of said sides, comprising break-forming a triangular channel strip with a gap between the outer edges of the converging sides larger than said spring-back,
bending the bottom of said channel outwardly between the bottom corners of said channel strip a desired amount by pressing the edge of a plate die through said gap against said channel bottom, said plate having a thickness no greater than the sum of said spring-back and the desired gap.
2. A method of forming a triangular channel strip of resilient sheet material normally having a desirably small gap between the outer edges of the converging sides of the channel which is less than the spring-back of said sides from a closed gap break-form position of said sides, comprising break-forming a strip into a W-shaped cross-section,
having substantially parallel outer sides and a suitable angle between the inner legs, the opposite angles at the other ends of the inner legs being of the required size to provide said desired gap when said legs are flattened into a substantially straight bottom of said triangular channel,
placing said strip on a flat surface with the W in upright position, and
pressing the top of the ridge formed by said inner legs by means of the edge of a flat plate die substantially no thicker than said desired gap until said inner legs are substantially a continuous flat bottom of a triangular channel bringing the outer edges of said outer sides of the W to bear substantially against the opposite sides of said flat plate, so that they will provide the desired gap.
