29 Claims. (Cl. 61-48) This invention relates to piers and to means and methods for isolation and control of res which may occur thereunder and more particularly to concrete tire wall, or bulkheads under piers, though in some of the claims the invention is not limited to piers or concrete walls.

One object of the invention is to provide an improved wall of this kind which may be installed without submarine equipment and which may be constructed in situ of concrete under the pier.

Another object of the invention is to provide an etiicient fire wall hanging under the pier and extending from the pier deck to below the water line.

Other objects are to provide a lire wall of this kind which will be rugged and durable, and will withstand shocks if the pier is struck by heavy boats.

Other objects of the invention are to increase the eX ibility of the iire wall while maintaining its functions and above advantages, and to this end to provide a tire wall of independently swinging sections eXibly connected in a manner to prevent the passage of re through the connections.

Another object of the invention is to provide a tirestopping barrier where the tire wall joins the pier deck.

Other objects are to provide improved methods of constructing the iire wall to elect the above objects.

Additional objects of the invention are to eiect simplicity and eiciency in such walls and methods and to provide an extremely simple wall of this kind which is rugged and durable in use, and economical to construct and maintain.

Still other objects of the invention will appear as the description proceeds; and while herein details of the invention are described in the specication and some of the claims, the invention as described in the broader claims is not limited to these, and many and Various changes may be made without departing from the scope of the broader claims.

The inventive features for the accomplishment of these and other objects are shown herein in connection with an improved tire wall or tireproof bulkhead and method of making the same, the wall being made as a single wall or as a number of wall sections flexibly joined and hanging across the space under the pier and extending below the water.

In constructing the wall section or wall under a pier, beams are placed on the pier stringers. The method includes suspending from said beams downwardly extending rods supporting a lower beam above the water line, and securing along the lower beam spaced parallel upright forms between which bolts, rods or cables are passed from said upper beam and secured to the lower beam; and concrete or other plastic material is poured between the forms on the lower beam to form a lower part of a lire wall section.

Then all parts of the lower beam and wall section are simultaneously lowered. The process of building up the form and the pouring are repeated until the wall section is below the water line and has been built up substantially Frice to the stringers, after which the rods, bolts or cables are secured to the upper beam after which the forms are removed to allow the rods, bolts or cables to support the wall.

In the accompanying drawing showing, by way of example, several of many possible embodiments of the invention,

Figs. 13, 14 and 15 are respectively fragmental side elevation, horizontal section and end elevation showing another form of anchoring means; and

Fig. 16 is a vertical sectional view showing means for suspending the re wall from a concrete pier deck.

In Figs. 1 to 3 are shown a complete iire wall section 10 and an incomplete section 11 beneath a pier 12 carried on transverse bents or rows of piles 13 having cross braces 14 and diagonal swing braces 15 secured thereto. Caps 16 on the respective bents or rows of piles support spaced stringers 17 disposed across and connecting the caps one to another. The pier deck comprises transverse deck planks 19 across the stringers and pier and diagonal oor or deck planks 20 or a concrete floor across the deck planks; or the entire deck oor may be of concrete, but herein a plank deck is described.

To erect the re wall under a plank deck, two deck planks and the floor planks above them are removed to leave a transverse opening 21 above the stringers near a bent or row of piles with proper clearance from the piles. Longitudinally slidable upwardly open upper channel beams 22 are placed in alinement with each other on the stringers in said opening substantially across the pier. These upper beams have short longitudinal slots 23 (Figs. 4 and 5) in the web at intervals and have flanges 24 nearly as high as the top of the deck lower planks.

Across the channel beam at intervals are disposed, during construction, tlat upper yoke pieces 25 having openings at each side of the beam in which are placed long threaded rods 27 on which are placed nuts 28 engaging the yoke piece, the rods initially extending much above the yoke piece and initially extending down to near'the water level at high tide, and are provided with lower end eyes 29 (Fig. 6) which support lower at yoke pieces 30 each having at the ends downwardly outwardly turned hooks31 engaging in said eyes. Across said lower yyoke pieces 30 are placed a temporary wooden -vbeam 32 or othersuitable beam to provide a temporary Afoundation for the tire wall, on which beam are nailed an upwardly open lower channel beam 35 havingY cross vpins 36 passingthrough the flanges at intervalscorre- .sponding to'said'slots 23 of the upper beam. Bolts or cables 37 are initially passed through said slots'23 and securedat their lower ends to said cross pins 36. If cables are used they are drawn taut.VV Bolts will remain uptight because of their stiffness.

Between the outer ends of the forms where the free end of the ltire wall is to be, there is secured an inwardly vertically dove-tailednpright end'piece 38 (Fig. y2) of oakor. .otherV material to form a protectiveV end edge or fender Vfor the wall; and between the inner ends of the fo'rmwhere the inner end of a wall section is to be, there is secured an upright end piece having a deep inner verltical tongue. to forma deep groove 39 (Fig. 8) in the concrete .to cooperate with aV similar groove 39 of an adjacent wall section 11 to form a space to receive a tireproof verticalr spline 40 of suitable 'reproof material. Wires 41 `(Fig. 6) are passed through the forms to tie thevforms ltogether to prevent their spreading apart when the concrete is poured.

Escutcheon plates 42 having horizontally elongated openings 43 therethrough are secured at opposite locatiops on the inner face of the forms adjacent to a pile to receive and hold a core 43 of horizontally elongated cross-section placed in the openings of the plates across thegrspace between the forms to provide holes 43a through the Wall for a purpose to be explained.

Y 'Ifhe concrete or other plastic material is poured between the forms while the bolts 37 are upright or said cables are taut to'form a lower part of a re wall section after which the nuts 28 supporting the section are simultaneously turned to lower the rods, lower beam and wall section to a new lower position for building up the forms and end pieces and repeating the pouring and process until the wallsection is below the water line at low tide and Yhas been built up substantially to the bottom of the stringers or the upper channel beams 22 as will be eX- plained.

VThe Vwall section may be built up solidly to the Yupper channel beam 22; or when the wall section is builtup to the bottom of the stringers 17 there may bevplaced on the wall reproof horizontal parting plates 45 (Fig. 4) across and along the top of the wall section just at or under the lower plane of the stringers. Then the forms and Yconcrete wall section Vare built up between the stringerssubstantially to the upper beam 22, a short tubular'forrn V46 having been placed on the plate around the b oltsfor cables: 37 between the stringers, whereby are formed Yconcrete lugs 47 having vertical openings therethrough, the 'lugs occupying the space between the stringers substantially to said upper beam 22.

Theobject of the parting plate 45 is to provide a smooth break between the lug 47 and the wall section if the pier should be struck and heavily jarred by a boat. It the parting plate be omitted a rough break might result, but would do no real harm. f

An eye bolt 49 having upper and lower eyes 50 and 51 has its upper eye 50 placed on a pin 52 passing through each pair of alined openings in the anges of the upper beam?" The upper end of the bolt or the cable 37 is secured'to the lower eye 51 of the eye bolts; after the i Wall is set the forms, cores, temporary beam, yokes 30 and long bolts 27 are removed to allow the bolts or cables 37 to support the wall section.

The operation is repeated to form the other end section of the wall, and one or more intermediate sections having slightly spaced vertical end edges having adjacent cooperating deep grooves 39, into which lgrooves are placed a spline plank 40 of reproof materialto form a ilexible yieldable reproof joint. Y.

An eye bolt 54 (Fig. 2) is loosely passed through the escutcheons 42 and openings 43 and 43a and has an eye 55 adjacent to a pile and a head or nut 56 at the opposite end. A pair of straps 57 at' oppositeV sides of theY pile are secured by bolts 58, 59 passing through the ends 'of the straps, one of the bolts 59 passing through the eye for loosely anchoring the wall to the pile.

The object of having the channel beam 22 slidable, and of having the bolt'loose in the escutcheon openings 43, is to allow some relative movement between the pier and the beam 22 and between the re wall and the piles and pier when the pier is struck and jarred laterally, thus to avoid excessive shock tothe cables or bolts 37 and the tire wall section.

If desired the wall section ldlc may be made thinner between the joints, as shown in Fig. 10, thusV requiring less concrete between the joints.

Instead of the joints being made as in Figs. 8 and l0 the concrete wall 10b 'may be cast in undercut grooves 60 (Fig. 9) of loosely tongued and grooved pieces 61, 6 of aluminum or other metal or material. i

Instead of erecting the walls as above described, the wall may be p'ret'abricated and transported to the pier and attached to the upper beam 22 by means of the eye bolts 49 and pins 52 as shown.

The form of the invention of Figs. 1l to l5 comprises a tire resisting wall or wall section 10a of concrete suspended from upwardly open alined shallow upperv channel beams 22a secured across adjacent stringers 17 having anges less high than theV adjacent planks 19 and as-wide as the space between adjacent planks 19.` Short planks 19a are 'alined between adjacent beams; Pending bolts or rodsn37a passing through bolt holes in the web of the channel beams and having nuts 63 on the upper end engaging the web for holding the bolts, support .the permanently installed lower beam 35a as will be explained. A 'concrete filling 64 between and ush with said adjacent planks 19 covers the beams and nuts.

Cross pins 36a passing through eyes 37b at the lower ends of the rods 37a support U-shaped straps 65 having holes in the upper ends of their arms received on said pins 36a. The lowerbeam 35a received in said straps', Y

supports the concrete'or other cast plastic lire wall 10a resting on said lower beam and extending upwardly to the stringers 17, upper beams 22a and short planks 19a.

An 'upright end piece 38a of oak or other material to form a protective end edgeL or fender for the wall land having countersunk holes therethrough is held in place by barbed studs 66 in said holes and cast in the wall and having heads 67 in countersinks 68 in said piece.

Means for preventing'lateral swinging of the walls but allowing endwise movement relative to the adjacent pile is shown in Figs. 13 to 15 and comprises a horizontal channel iron 70 having a vertical web 71 disposed against adjacent piles 13 of the same pylon, and having a horizontal slot 72 in its mid-part. U-straps 73 disposed around adjacent piles 13 are bolted to the web by bolts 74. A non-traveling slide plate 75 welded fast on the anges ofy said channel iron is provided with a horizontal slot 7 6' registering with the slot 72 of the channel iron, said slots receiving a threaded bolt 77 transfersely slidably disposedin said slots and having one end welded or riveted to an anchor plate 78 cast mid-way between the wide faces of the wall. i

Horizontallyvmovable.slide plates 79, 80 having centralY openings received on said bolt `77 Yare* welded to the boltv arance? and -slidable on said non-traveling plate and the channel iron to allow horizontal relative movement between the piles and the wall parallel to said faces and parallel to the wall as when the pier is jarred laterally. A reinforcement of expanded metal 81 is cast in the main plane of the wall to strengthen the wall.

The walls or wall sections of Figs. ll to 15 may be constructed by using the rods 27 substantially as those of Figs. l to 3; but the temporary beam 32 need not be employed, as the yoke piece 3i) may be placed directly beneath the lower beam 35a, and the forms 32a (as in Fig. 6) may be rested directly on the beamsa.

It' the pier deck 19C (Fig. 16) is made of concrete it may be provided with cut-out recesses S2 in its top face and bolt holes S3 from the mid-part of the recesses passing down through the deck; and receiving plates 84 on the bottom of said recesses have countersunk holes receiving pending rods or bolts 37C in said holes 83 and having heads 85 disposed flush in the countersinks and covered by a concrete lling 86 in the recess flush with the top of the deck and covering said heads and plates.

Where wooden decks are used a part of the planking could be cut away or omitted and have a concrete portion substituted, the concrete wall being built up to said portion.

If desired, the plate 78 could be omitted and an eye formed on the tie bolt '77 and disposed on one of the bolts 37a for anchoring the tie bolt.

In general any of the features of any of the species herein may be used with the features of the other species if suitable and desired.

This application is a continuation in part of my abandoned application Serial No. 9,536, led February 19, 1948.
