Patented May 19, 1953 ANCHORED CORRUGATED DECKING Adolph Carl Weber, University City, Mo., assignor to Laclede Steel Company, St. Louis, Mo., a corporation of Missouri Application June so, 1949, Serial Nb. 102,243
1Claim. ((31.189-35) I This invention relates generally to building structures, and particularly to anchors for securing sheet metal to steel joists.
The use of poured concrete slabs for floors and ceilings of building structures has become common practice. In connection with such concrete slabs,corrugated sheet metal, remaining in place after the concrete has been poured, is laid over steel joists to support the concrete. This has been found to be highly desirable for strength, economy, and speed of, construction. n
One of the principalhtime-consumingoperations in such use of corrugated metal sheets is the anchoring of the sheets to the joists, which must be performed in order to hold each sheet in place to prevent displacement during installation of the sheets and subsequent abuse, including the pouring of the concrete.
Oneobject of this invention is to provide a simple device for rigidly and securely anchoring corrugated sheet metal to steel joists. Other objects will become apparent to those skilled in the art when the following description is read in connection with the accompanying drawings, in which:
Figure 1 is a perspective view showing corrugated sheets in staggered relation, anchored to steel floor joists in accordance with the present invention;
Figure 2 is a sectional view at 2--2 of Figure 1, showing particularly the position of the anchor clip in the anchored position with respect to the steel joists;
Figure 3 is a sectional view at 3-3 of Figure 1, showing particularly the position of the anchor clip in the anchored position with respect to the corrugated sheet metal; and
Figure 4 is a perspective view showing in detail the use of the anchor in punching the hole through which it is to be inserted.
In accordance with the present invention, corrugated sheets of such stiffness as to avoid excessive sagging under the weight of concrete, and of such length as to span at least two joists, is
laid with ends and sides overlapping in staggered relationship, so that the joists in one course are bridged by an integral sheet in the adjacent course, as shown in Figure 1. The corrugated sheets thus laid are anchored expeditiously and positively to the supporting steel joists by means of anchor clips. In outline, these anchor clips are T-shaped in front elevation, and roughly L- shaped in side elevation. They are so constructed that when the L-shaped member is inserted through a corrugated sheet and between and beyond the supporting bars of the steel joist upon which the sheetrests, and when the clip is then turned through roughly the member forming vthe horizontal part of the L engages the lower edge of one of the top chords of the joist, while the T-shaped cross member, at right angles to the projecting L-shaped member, bridges a pair of corrugations in the sheet. The shank of the anchor clip, which forms the vertical element of both the T- and the L-shapes, is of such a length as to hold the sheet down securely onto the joist bar when the clip is in its anchoring position. The cross member forming the horizontal part of the T is adapted to be used as a convenient punch.
The anchor clip is described more particularly by referring to the drawings, in which I represents corrugated sheet metal supported by steel joists 2. Joists 2 are equipped with spaced bars or angles 4 forming a top chord and supporting surface. The corrugated sheets I are secured to joists 2 by means of anchor clips consisting of a crossbar 5, a shank 6 with which crossbar 5 makes a T-shaped profile in front elevation, and a member I with which shank 6 makes an L- shaped profile in side elevation, projecting from shank 6 at substantially right angles to crossbar 5. While the projecting member I is said to make an L-shaped profile with shank 6, the angle between members 6 and 1 may be made somewhat obtuse to facilitate engagement of the projecting member I with one of the bars 4, and to provide or augment the wedging effect, later described.
As shown in Figure 4, the crossbar 5 may be used with the aid of a hammer to punch the hole into which the L-shaped portion of the anchor is inserted. While for this purpose the end of the crossbar may be tapered or wedge shaped, this has been found to be unnecessary. It has been found preferable to punch the hole and insert the anchor through a single thickness of sheet, relying upon the overlapping edge of that sheet to secure an underlying edge of the adjoining sheet. The hole is punched in the vicinity of the bottom of a valley in the corrugated sheet, directly between the spaced bars 4 forming the supporting surface of the joist. The anchor is inserted with the projecting portion 1 of the clip disposed longitudinally of the joists between the bars 4, in which position the crossbar 5 is disposed parallel with the valley in which the hole is punched. The shank 6 of the anchor is of such length with respect to the bars 4 and the depth of the corrugations in sheets I, that when corrugated sheeting against chordsgand makes turning, especially thezinitial the anchor is turned through roughly 90 after the projection 1 has passed the far edge of the bar 4, the projection I is pulled up tightly and the corrugated sheet is pulled down tightly against the joist bars.
When the spacing of the joist bars 4 is considerably greater than the diameter of the clip shank 8, the anchor :clip will tend to cant, as shown in Figure 2. In that event projection 1 acts to produce a wedging effect as the clip is turned to its anchoring position, even when the projection 7 makes a right angle with the shank B. When the spacing of the bars 4 is only slightly greater than the diameter of the shank 6, or in any event to supplement the "wedging action and to make engagement of the projection I with the bar 4 and initial turning of the clip more facile, the angle between the projection 1 and the shank 6 may "be made somewhat obtuse. It can be seen :that with such a construction, as with the canted right angle clip,
the vertical distance between the lower edge :of the joist chord 4 and the clip crossbar 5 must decrease as the point of contact between pro- ,jection l' and bar 4 moves from the outer end of projection 7 toward'shank Therefore, this wedging efiect, heretofore referred to, acts aver.- tically against the clipcrossbar 5 to clamp the the supporting turning, of the crossbar against "the corrugations easier.
A device for securing corrugated sheets to metal joists is thus provided which is easily and quickly installed, which may itself be utilized in puncturing the hole in the corrugated sheet through which itis to be inserted, which isself- -wedging, effects .a positive :as opposed to merely :frictional lock, and is sturdy, efficient, and cheap sin the light of its utility.
Having thus described the invention, what is claimed and desired to be secured by Letters Patent is:
In a deck wherein corrugated sheeting having valleys and crests is laid upon and anchored to joists having spaced upper chords, the combination of an anchor clip having a shank, a projecting part at one end of said shank, said projecting part being of greater length than the ,Width of the space between said chords, and a crossbar at the other end thereof, said shank extending-through a hole in a valley of said sheeting and between said spaced upper chords of a joist, the projecting part engaging an edge of one of the upper chords of said joist below the sheeting, and the crossbar engaging a crest of said. ssheeting adjacent said hole.
