SHORING CLAMP Filed May 2, 1958 lNVENTbR. WILL/AM s. DODGE $3 M, mm 5 M SHORlNG CLAMP William S. Dodge, San Francisco, Calif., assignor to Matson Navigation Company, San Francisco, Calif.

Claims. (Cl. 105-369) This invention relates to a beam shoring clamp, and has for one of its objects the provision of a device adapted for use in positioning and holding studs between decks in a ship, which studs may be in a shoring fence employed in securing cargo.
Another object of the invention is the provision of beam shoring clamps adapted to support studding used in the shoring fences for securing cargo, and which clamps may be removably secured to the beams at any of the points desired along said beams, irrespective of the camber of the latter, for holding the studs at their upper ends when the studs are supported on the deck below said beams.
A still further object of the invention is the provision of a beam shoring clamp that is simple, economical to make and to use, and that is adapted to firmly but releasably grip the horizontal lower flanges of a conventional steel deck supporting beam at any desired point along the latter, and which clamp is provided with means for slidably receiving the upper end of studs used in a shoring fence to support such upper end irrespective of the length of the stud, provided it is of sufficient length to project into said means when supported on a deck below the beam.
The principle involved in the design is to provide positive locking means for the studs of a shoring fence at the points of greatest strain, i.e., at the top of the shoring. The manner in which the studding is secured at the deck level is not here involved. It is important, however, that the beam clamps for the upper ends of the studs be applicable, with equal facility, to any normal condition that is encountered, and that they should not be secured to the studs, as by clamps, nails, screws etc.,.nor should the lengths of the studs used be critical in order that the clamps be effective.
Other objects and advantages will appear in the description' and in the drawings.
In the drawings: I
Fig. l is a vertical sectional view that is illustrative of a stud in a shoring fence disposed between decks and held at its upper end by a shoring clamp.
Fig. 2 is an enlarged sectional view taken along line 2-2 of Fig. l and broken in length.
Fig. 3 is a sectional view of the lower end of a stud where there is a wood ceiling.
Fig. 4 is an exploded view of the beam shoring clamp used at the upper endof each stud; 1
It is to be understood that Fig. 1 is merely illustrative of one application of the beam shoring clamps, inasmuch as they are equally useful for construcing special storage compartments where and when needed, and for use on transverse framing members for lateral bracing of cargo, explosive magazines, grain shifting boards, and/or feeders, etc. The clamp itself in each instance will be substantially the same.
In detail, Fig. 1 shows a deck supporting beam 1 extending thwartwise of the ship, and a shoring fence 2 that includes a stud 3 extending between deckhead 4 and deck tates Patent v 2,976,823 Patented Mar. 28, 1961 5 and which stud is held at its upper end to beam 1 by a shoring clamp 6, the latter being shown in detail in Fig. 4. p
The conventional beam 1, as seen in Fig. 2, comprises a vertical, horizontally extending web- 7 having a horizontal flange 8 integral therewith along its lower edge. The web 7 is welded along its upper edge to the deckhead 4. The beam 1 and the deckhead have the usual camber.
The beam shoring clamp employed is identical where there is a wooden ceiling such as indicated at 9 in Fig. 3, being understood that the ceiling 9 is normally on a steel deck.
The clamp 6 comprises a vertically disposed and vertically elongated plate 10 that is formed with a rectangular opening 11 approximately centrally between its ends and between its vertical side edges.
The portion 12 of the plate 10 above the opening 11 may be called a clamping jaw, inasmuch as this portion is adapted to be clamped against the face or beam-Web side of the beam 1, as seen in Fig. 2.
A lateral projection 13, integral with the lower end of I the plate provides a rectangular opening one side of in cross sectional contour.
which is the lower end of the plate 10. This projection 13 is adapted to slidably pass therethrough the upper end of stud 3, the latter usually being approximately 4 x 4" stud will be at the same side of the plate 10 as the projection 13, and at the beam-web side of the beam 1.
An element 14 is at the side of the plate 10 opposite to the projection 13, and said element is approximately the same width, from its upper to its lower end, as plate 10 and is formed at its upper end to provide a laterally directed channel portion 15 adapted to receive the flange 8 therein. Thus the open lateral side of the portion 15 will be directed toward the clamping jaw 12, which jaw, as has been noted, is the upper end of plate 10.
The upper side 16 of the channel portion 15 is shorter than the lower side 17 (Fig. 4). By this structure, when the flange 8 is seated against the bottom of the channel 15, the lower side 17 of the channel will terminate fairly close to plate 10, although the upper side 16 does not reach the web 7 of flange 1.
The leg 18 extends a distance below opening 19 andis; formed along its lower edge with a foot 20 that projects is adapted to draw the channel portion 15 of element 14 and the jaw 12 of plate 10 tightly against the beam 1, with the flange 8 in said portion 15 and jaw 12 against the beam-web side of the beam. Thus the channel portion 15 forms a clamping jaw that is opposed to jaw 12. The foot 20 functions as a fulcrum about which the channel portion or jaw 15 may swing.
"Assume the shoring fencing is to be installed betweena steel deckhead 4 and a steel deck 5. After cargo 25' is stowed (Fig. 1) the conventional fence 28 is positioned against it. Studs 3, each with a clamp 6 at its upper end, are positioned adjacent to the beams 1 with jaws 12, 15 of the clamps at opposite sides of each beam with flange 8 of each beam in the jaw 15. Each stud may be moved tightly against the fencing and each clamp is then tightened against the beam that is between the clamping jaws by tightening each nut 24. Counter driven wedges 26, 27 (Fig. 2) extending fore and aft below each stud will function to force the stud against the deck- Thus the upper end of said head 4, and will hold the lower end of each stud in position with adequate firmness.
Where there is a wooden ceiling 9 (Fig. 3), cleats 29 may be toenailed to the studs 3 and the cleats nailed to the ceiling at the inboard sides of the studs. The lengths of the studs may vary, provided they extend through the projections 13 of the clamps.
The degree of the camber of the beam is immaterial, since the element 14 is adapted to pivot about the'axis of the bolt 21 so that the stud may be held vertical but the element 14 may pivot to follow the flange 8.
By the above system in which the clamping elements 14 are employed, the studs are quickly adjustable to different positions along the beams and may be secured to the beams in adjusted positions of the studs. Also the clamps and studs are quickly removable and no projections are left on the deck or ceiling. Furthermore, the lengths of the posts are not critical, and the clamps may be quickly slipped off the studs.
It is to be understood that the illustrations and descriptions are not intended to be restrictive of the invention, and the claims are intended to cover modifications coming within the scope of the invention.
