Definitions

  • the present invention pertains to the construction of elevated structures such as bridges, piers or docks, offshore structures, and elevated platforms of various types.
  • the method of the invention is useful when it is necessary to build such structures in difficult environments, e.g. over bodies of water. However, it is likewise suitable for many other construction projects, such as the building of overpasses and the like in highway construction.
  • At least one construction component is emplaced at a construction site supported by an underlying earth formation.
  • Such support may be direct, as where the component rests directly on the ground, or indirect, e.g. by means of suitable pilings or the like.
  • one end of the component may be supported directly and the other indirectly.
  • the method includes the positioning of a second construction component adjacent the first component
  • the second component is then supported in cantilever fashion on the first component by locking said second component to said first component
  • Support means is then extended downwardly with respect to the second component into load bearing engagement with the earth formation.
  • the second component is interlocked to the support means for support thereby.
  • the two components are longitudinal components, and the first is so emplaced with both ends thereof supported by the earth formation.
  • the second component is positioned with one end thereof adjacent one end of the first component, whereafter the adjacent ends are locked together to effect the aforementioned temporary cantilevering of the second component from the first component.
  • the support means are extended from the second component, they are so extended distal that end which is locked to the first component, so that, after the second component is interlocked to the support means, it is then fully supported, i.e. supported at both ends, on the earth formation, whereafter it can be used as a base for further building out of a third component.
  • the support means comprise pilings extending generally through guide assemblies carried on the longitudinal components and driven into their load bearing engagement with the earth formation.
  • the method may be performed using a construction system, including relatively simple girders, transom members, and T-head locks, all as disclosed more fully in prior U.S. Application Serial No. 704,500, of which this is a continuation-in-part.
  • the text of Application Serial No. 704,500 is hereby expressly incorporated herein by reference.
  • the longitudinal components may be of the type disclosed in U.S. Patent Application Serial No. 757,631, of which this ia continuation-in-part, and having lock assemblies of the type likewise disclosed therein.
  • the text of Application Serial No. 757,631 is hereby expressly incorporated herein by reference.
  • Spud well components also disclosed in said Application Serial No.
  • 757,631 may be connected to the general components by such locks to serve as guides for driving the aforementioned pilings.
  • These spud well components are preferably connected to the general components adjacent their longitudinal ends, either directly on their end faces, or on the end portions of their side faces.
  • At least three basic types of construction components may be used in the context of the present invention. These are (1) the general construction component, a fairly simple component of generally rectangular parallepiped form, which forms one of the basic building blocks of the construction system; (2) rake components, whose undersides are graduated or tapered, e.g. for use at the ends of a bridge which rest on the opposite shores being bridged or on the ends of docks or piers; and (3) spud well components, which are adapted to receive elongate spuds of either the load bearing or locating type, and which can be connected to the other components to adapt them for appropriate association with load bearing or locating spuds or pilings.
  • the general construction component a fairly simple component of generally rectangular parallepiped form, which forms one of the basic building blocks of the construction system
  • rake components whose undersides are graduated or tapered, e.g. for use at the ends of a bridge which rest on the opposite shores being bridged or on the ends of docks or
  • a general construction component of the present invention has thereon a plurality of male and female lock assemblies, generally similar to the lock assemblies disclosed in prior U.S. Patents No. 2,876,726, No. 3,057,315, and No. 3,805,721, arranged in vertically spaced pairs of like gender. These assemblies are adapted for engagement with respective female and male lock assemblies of a similar construction component for locking the two components together, for various purposes, including the temporary cantilevering described above.
  • the generally horizontally disposed pin member is reciprocable with respect to the construction component between an advanced position in which it protrudes significantly from a lateral wall of that component and a retracted position in which it lies generally within the gross dirrien- sions of the component (i.e. in which it does not protrude from the component by a distance sufficient to interfere with its handling in the manner of a standard freight container).
  • the gross dimensions of the component may be chosen to generally correspond to those of a standard freight container.
  • the pin members may be disposed in their retracted positions, and the component on which they are carried may further be provided with standard container fittings whereby the container may be lifted, lashed, and otherwise handled in generally the same manner as such freight containers.
  • the pin members may be placed in their advanced positions for engagement with mating female assemblies of another component to be connected.
  • the male lock assemblies of each construction component are arranged in tandem pairs, the two male lock assemblies of each such pair being vertically spaced from each other along a lateral wall of the construction component
  • the female lock assemblies are similarly arranged in tandem vertical pairs.
  • the pin members of the male lock assemblies are rigid.
  • the present invention is designed to specifically prevent any substantial hinging action between adjacent connected construction components. Nevertheless, the pin members and other movable parts may be made sufficiently small so as to be manually movable with simple hand tools.
  • the present invention provides a scheme which allows the profile of the lock assemblies to be reduced so as not to interfere with shipping and handling of the construction component on which they are carried in the manner of a standard freight container. Nevertheless, after such shipping and handling, substantially horizontally extending pin members may be advanced to provide all of the advantages of the types of lock assemblies generally disclosed in prior U.S. Patents No. 2,876,726, No. 3,057,315, and No. 3,805,721.
  • the specialized construction components of the present invention are preferably somewhat smaller than standard freight containers. Nevertheless, it is not practical to place these specialized components within standard freight containers for transportation. Accordingly, the present invention includes a system whereby two or more of these smaller components can be connected together, in some cases along with other auxiliary elements of the transportation system, to form an assembly which, in turn, can be handled and shipped as a standard freight container. Then, when the assembly has reached the construction site, the components can be disconnected from the transportation configuration and reconnected with one another and/or with additional components, of either the general or specialized type, in different configurations so as to form the structure being constructed.
  • connection means which are used to connect the small specialized components to one another in their transport assemblies be the same connection means which are used to connect various construction components together to form the structure being constructed. More particularly, it is preferred that these connection means include the improved, retractable pin, lock assemblies described hereinabove. As is the case with the general, container sized, construction components, the retractability of the pins prevents those pins not used to connect the transport assembly from interfering with handling of that assembly as a standard freight container.
  • the rigidity of the pins utilized in these preferred lock assemblies provides a sufficiently rigid assembly for transportion and handling without the need for the assembly to be enclosed within a container. This is largely due to the aforementioned features of the tandem lock assemblies, with their rigid pins, which tend to prevent relative pivotal movement of components connected thereby, and this effect is further enhanced by shear bearing formations.
  • Another object of the present invention is to provide such a method which includes transporting and handling the construction components in the manner of standard freight containers prior to formation of such structure.
  • a further object of the present invention is to provide such a method in which pin members of the lock assemblies on such construction components are retracted for such transportation and handling, and extended for the formation of such structure, including locking of components in cantilevered configuration.
  • Still another object of the present invention is to provide such method in which at least some of said construction components are connected together to form assemblies which may be transported and handled as standard freight containers
  • elevated structure will mean any structure of which at least part is spaced above the underlying earth formation as by pilings or other supports.
  • Non-exclusive examples include: bridges, overpasses, offshore platforms and piers.
  • first span of the platform to be constructed comprises five longitudinal construction components 11 connected side-by-sde by transom components 29.
  • Each longitudinal component 11 comprises an elongated girder 13 and a pair of pile guide assemblies 15, each of which is affixed to a respective one of the two ends of the girder 13.
  • each end of each of the girders 13 has a pair of arms 17 extending longitudinally outwardly from opposite lateral sides thereof to define a channel 19 therebetween.
  • the respective pile guide assembly 15 is square in transverse cross section, and the channel 19 is correspondingly shaped to abut the outer sides of the pile guide assembly 15 on three sides.
  • Arms 17 are sized to extend approximately half way across the pile guide assembly 15, so that half the pile guide assembly protrudes endwise from the girder 13.
  • arms 17 carry primary locking means. At each end of each girder 13, one of the two arms 17 carries a pair of vertically spaced primary female locks 21, and the other arm carries a pair of vertically spaced male locks 23 so that there are a total of four locks on each end of the girder 13.
  • Each girder 13 also has a plurality of auxiliary female locks 25 mounted on its lateral sides.
  • Transom construction components 29 have, on their ends, auxiliary male locks 27 designed for cooperation with auxiliary female locks 25.
  • Each of the transom members 29 is generally in the form of a truss including upper and lower horizontal members diagonal bracing members and vertical end members. These members are rigidly affixed to one another in any suitable manner, as well known in the art, e.g. by welding.
  • the girders 13 may take various forms, as will be apparent to one of skill in the art, and in particular may be provided with closure skins of sheet metal so that they may be made buoyant. Girders 13 would typically also include suitable internal struts and/or other reinforcing means, as would be apparent to one of skill in the art.
  • the assembly 15 includes a housing or casing comprising side walls 41 which define the aforementioned square transverse cross-sectional configuration.
  • Upper and lower end walls 43 and 45, repsec- tively, are rigidly affixed to side walls 41 in a suitable manner, e.g. by welding.
  • Upper wall 43 has a central opening 47. Slightly below the upper extremity of upper wall 43, and integral therewith, are a plurality of lips 49 circumferentially spaced from one another about opening 47 and extending radially thereinto. Upper wall 43 is also provided with slots 51 located outwardly of central opening 47 near the four comers of upper wall 43.
  • Lower wall 4 5 has a central opening 59 in register with opening 4 7 of upper wall 4 3.
  • a short cylindrical skirt or lip 63 extends upwardly adjacent opening 59, and a sleeve 65 of like inner and outer diameters is affixed to and extends upwardly from lip 59 to a point spaced somewhat below upper wall 43.
  • the upper end of sleeve 65 is braced against side walls 4 1 by a horizontal plate 3.
  • a central throughway is defined in assembly 15 by opening 59, the interior of sleeve 65, the hollow gap between the sleeve 65 and wall 43, and opening 47.
  • a flange 67 integral with lower wall 45 extends laterally outwardly beyond lateral walls 41 so as to form a square rim extending about the entire periphery of the pile guide assembly 15 at its lower extremity.
  • Flange 67 underlies and abuts the end of the attached girder 13 and its arms 17.
  • Interlock member 69 is associated with upper wall 43 of the pile guide assembly 15.
  • Interlock member 69 includes an upper horizontal plate 71 having a central bore 73 with slots extending radially outwardly therefrom.
  • Member 69 further comprises a cylindrical skirt 77 extending downwardly from plate 73 and spaced inwardly from the outer extremity of plate 71 so that it can pass through lips 49.
  • a plurality of lugs 79 formed integrally with skirt 77 extend radially outwardly therefrom, spaced circumferentially from one another. Lugs 79 are sized so that, if aligned with the portions of opening 47 between lips 49, skirt 77 can be lowered through opening 47 until the outer edge of plate 71 rests on lips 49.
  • such support of member 69 is provided by support means in the form of cylindrical pilings 81, each of which is associated with a respective one of the assemblies 15.
  • skirt 77 is sized to surround piling 81, and that if piling 81 is disposed within assembly 15, plate 71 may rest on its upper end, and with lugs 79 underlying lips 49, member 69 may thus interlock assembly 15 to piling 81 for support thereby.
  • Skirt 77 has a relatively loose fit about piling 81, to avoid jamming, while sleeve 65 and rim 62 may have a closer fit for guiding piling 8 1 .
  • the primary locks 20 and 22 and the auxiliary locks 24 and 26 may be of any suitable type including rigid, horizontal pins adapted to serve as at least one means to prevent pivotal or hinging action between adjacent connected construction components, particularly when the lock assemblies are arranged in vertically spaced pairs, as shown. This prevention of hinging or pivoting allows the cantilevering, to be described more fully hereinafter.
  • the lock assemblies may be of the T-head type more fully described in prior Application Serial No. 704,500, of which this is a continuation-in-part. or of the type described more fully below in connection with Figs. 8 et. seq. Other types of lock assemblies may also be utilized.
  • the exemplary construction procedure will be that of forming an elongate elevated platform in a shallow body of water.
  • a first span is formed by assembling construction components in accord with the present invention.
  • This first span includes five of the elongate primary construction components 13, 15 arranged parallel, side by side, and laterally spaced apart. Components 13, 15 are connected in such relation by transom components 29.
  • each transom component 29 may be lowered into the space between a pair of adjacent girders 13, but offset along the length of the girders 13 from the locus of the auxiliary female locks 25 to which it will be connected.
  • the transom member is lowered in this offset position until the lower male locks 27 have cleared the upper female locks 25, i.e. are disposed lower than such female locks. Then, the transom member may be moved lengthwise along the girders 13 until it is aligned with'the female locks 25. Next, the transom member is further lowered and suitably guided until the upper lock assemblies, 25 and 27, are aligned and the lower lock assemblies 25 and 27 are aligned, whereafter each pair of aligned lock assemblies 25 and 27 are locked together.
  • the first span may either be pre-assembled or assembled at the construction site. In any event, the span is positioned over the construction site, in this case floating on the body of water 153. Either before or after such positioning, the interlock members 69 are removed from their respective guide assemblies 15, and a piling 81 is lowered through the central throughway of each guide assembly 14.
  • the first span is temporarily anchored in a proper orientation with respect to the bottom 155 of the body of water 153, by well known means (not shown) while pilings 81 are driven downwardly into load bearing relation with bottom 155. This may be done, for example, by suitable power hammer means either supported on the first span itself or on an adjacent platform or vessel. Decking (not shown in Figs. 1 and 2) may be emplaced on the top of the first span to bridge gaps between the various construction components.
  • the pilings 81 are cut off at their upper ends, if necessary, so that each extends upwardly by a distance corresponding to the intended height of the finished platform, and interlock members 69 are placed on the tops of respective pilings 81.
  • the first span is elevated on the support pilings 81 by use of jacks.
  • jacks may be of any suitable form, and do not, per se, comprise a part of the present invention. However, to clarify the method of the present invention, a simplified form of jack is shown in Figs. 6 and 7.
  • Each jack includes a hydraulic cylinder 157 within which is a piston having a piston rod 159 extending outwardly through the lower end of cylinder 157.
  • the lower end of piston rod 159 is provided with a fitting 161 adapted to engage the central opening 73 of a respective one of the interlock members 69.
  • Rigidly affixed to cylinder 157 is a support frame 163.
  • Tie rods 165 are attached to frame 163 and extend downwardly through slots 51 in the upper wall of guide assembly 15.
  • the lower ends of the tie rods 165 are connected to upper wall 43 as by enlarged T-heads 167 which engage the underside of wall 43.
  • pilings 81 are pre-cut to an appropriate length so that, when the first span has been elevated to the desired height, their upper edges lie generally flush with the upper surfaces of tongues 49.
  • the interlock members 69 With pilings 81 adjusted to the appropriate height, and interlock members 69 in place on their upper ends, the interlock members 69, having been first positioned with their lugs 79 circumferentially offset from tongues 4 9 for passage therethrough, are rotated to bring lugs 79 into underlying relation to tongues 49.
  • the interlock members 69 rest on their respective support pilings 81, and the guide assemblies 15 in turn rest on the interlock members 69, specifically their lugs 79, thereby supporting the first span on the pilings.
  • decking 5 has not been previously emplaced on the first span, it is emplaced at this time.
  • the structure is now ready for building out a second span from the first span.
  • the second span will be similar to the first span in that it will be comprised of five parallel longitudinal components interconnected by transom components. However, the primary construction components of the second span will differ from those of the first span in that they will have guide assemblies 15 at only one end of each girder 13'.
  • each girder 13' of the second span is positioned in end-to-end relation with a girder of the first span, and in particular, that end of the girder 13' which has no guide means therein is positioned adjacent one end of a girder of the first span so that its channel 19 may surround the portion of the guide assembly 15 protruding from the first girder and the end of the second girder and its arms 17 may rest on flange 67.
  • a worker standing on the first span may then operate the primary locking means to connect the second girder 13' to the first girder 13 in cantilever fashion. Some vertical shear loading can be transmitted through the locks. However, most of the vertical load may be taken through flange 67 of guide assembly 15 to piling 8 1 .
  • All girders 13' of the second span are connected endwise to respective girders 13 of the first span in like manner, then to one another by transom components 29. Pilings 81 are then driven downwardly through the guide assemblies 15 distal the first span into load bearing relation with the floor 155 of the body of water 153. Then, utilizing interlock members 69 identical to those described hereinabove, the second girders 13' are interlocked, via guide assemblies 15, to the support pilings 81. When all of the second girders 13' have been emplaced and interconnected by transom members 29, decking 5 may be placed on top of the second span to bridge the gaps between the girders and/or transom components.
  • Fig. 5 shows laterally adjacent portions of the second span in various stages of completion. Additional spans can be similarly added on to construct a platform of any desired length.
  • Disassembly and removal when desired, can be accomplished, in essence, by reversing the steps outlined above.
  • the pilings 81 would not ordinarily be completely removed from the underlying earth formation. Rather, a longitudinal construction component to be removed would be disengaged from its piling(s) by removal of interlock member(s) 69.
  • the girder in question would be suitably supported, as by a crane or the like resting on a portion of the structure not yet being disassembled, and the primary locking means would be disengaged to free the longitudinal construction component.
  • the longitudinal construction component would then be lifted vertically upwardly and out of engagement with piling(s) 81 by the aforementioned crane or the like. After a given longitudinal component has been thus removed, any piling or pilings previously associated therewith can be severed at an appropriate level, e.g. adjacent the surface of the underlying earth formation, or in some cases, may simply be left in place.
  • the method may be varied somewhat depending upon the type of structure being formed and the type of earth formation underlying that structure. For example, in some cases, it is not necessary to elevate the first span before adding the second span. In other cases, the entire first span need not be supported on pilings. For example, in constructing a bridge, one end of the first span may rest directly on a bank (and be suitably anchored thereto), and the distal end, below which the bank slopes down toward the body of water, can be supported on pilings, and a second span built out therefrom.
  • the structure can be extended laterally in an incremental fashion using basically the same method as is used for the incremental longitudinal building of the structure, i.e. by supporting a first construction component on the underlying earth formation, locking a second component to the first component in cantilever fashion, extending support means downwardly from the the second component into load bearing engagement with the earth formation, and finally interlocking the second component to its support means for support thereby.
  • the lateral connections between girders 13 are adapted to be made via the transom members 29, the step of locking the second component to the first in cantilever fashion will preferably be accomplished by first locking two or more transom components to the first component and then locking the second girder in turn to the transom components.
  • Such a modification might be used, for example, where an elongate structure such as a bridge is being built out lengthwise according to the present invention, and at selected points along its length, widened areas are desired, e.g. to serve as pull-out points for vehicles which must, for one reason or another, stop on the bridge.
  • Such modification might also be employed where a structure of irregular configuration is desired for some other reason.
  • Fig. 8 represents a general construction component 10 according to the present invention incorporating improvements in the apparatus described and illustrated in prior U.S. Patents No. 2,876,726, No. 3,057,315, and No. 3,805,721. Such improvements will be described in detail hereinafter. Otherwise, the component 10 and the lock assemblies carried thereby may be assumed to incorporate the various features disclosed in said prior U.S. patents. Accordingly, U.S. Patents No. 2,876,726, No. 3,057,315, and No. 3,805,721 are hereby expressly incorporated herein by reference.
  • the construction component 10, as shown, is a buoyant type, so that it may be used in constructing floating bridges, barges, floating piers or docks, floating platforms, and the like. It will be appreciated, however, that the component 1 0, along with similar components, could likewise be used in the construction of various non-floating structures, such as land supported bridges, platforms, etc. Construction components specifically intended for the latter type usage may or may not be made buoyant, as desired.
  • component 10 is in the form of a rectangular parallelepiped.
  • Component 10 includes an internal force bearing framework, to be described hereinafter, which is generally encased within an outer covering including an upper wall 12, a lower wall 13, and four lateral walls.
  • the lateral walls in tum are subdivided into end walls 14 and side walls 16.

  • the gross dimensions of component 10, measured between the outer surfaces of its various pairs of opposite walls. generally correspond to those of a standard freight container.
  • the gross dimensions of component 10 may correspond to those of any of the standard size containers listed in the leaflet "ISO Container Dimensions" filed herewith and hereby expressly incorporated by reference.
  • the present invention could be adapted to other container sizes which may become standard in the future.
  • component 10 generally corresponds to those of a standard freight container, it is meant that any projections formed by the container fittings 18 or the various parts of the lock assemblies to be described hereinafter, when those lock assemblies are placed in suitable positions for transport, do not project beyond the outer surfaces of the walls of component 10 by distances such as to interfere with the shipping and handling of component 10 in generally the same manner as a standard freight container.

  • Assembly 20' further includes a pin member 58' which is identical to the pin member 58 of the upper male lock assembly 20 and oriented in the same manner. Because the pin members 58 and 58' are identical, and because their locking grooves, e.g. 62 and 68, extend completely therethrough in the vertical direction, it is possible for the lock member 75 of lower male lock assembly 20' to be oriented in the same manner as the lock member 7 4 of upper male lock assembly 20, i.e. with its bridge section uppermost and its rails or tines extending downwardly therefrom.

  • an inverted-U-shaped latch spring 90 is mounted on rods 82.
  • Spring 90 is substantially identical in structure and function to that of prior U.S. Patent No. 3,805,721, and thus, will not be described in great detail herein. Briefly, spring 90 is biased rearwardly so that, when the locking members 74 and 75 are in their locking positions, as shown in Fig. 11, the upper end of spring 90 is disposed beneath the upper wall 35 of housing 34 just adjacent opening 84. When it is desired to raise the lock members 74 and 75, a tool can be inserted in notch 84a to pry spring 90 forward so that the lock members can be raised. Then, whenever the lock members are again lowered to their locking positions, spring 90 will automatically snap back into a latching position under the upper wall of housing 3 4 .
  • the rear wall 38 of housing 34 has a pocket 92 extending rearwardly therefrom for sliding receipt of the tail end 72 of pin member 58.
  • a helical compression spring 94 is interposed between the bottom of pocket 92 and a shoulder 96 on the tail end 72 of pin member 58 to bias pin member 58 forward.
  • a pin retainer in the form of spring 98 is carried on the underside of pin member 58.
  • Spring 98 extends generally longitudinally along pin member 58. Its rear end is anchored on pin member 58, while its forward end is free and biased outwardly away from pin member 58. However, spring 98 can be biased inwardly so that it fits into a groove 100 (see Fig. 16) in the underside of pin member 58.
  • spring 94 can be inserted through socket opening 56 and into pocket 92. Pin member 58 is then inserted through socket opening 56, such insertion being permitted by the fact that the vertical dimension of pin member 58 nowhere exceeds that which might pass through socket opening 56. As the pin member 58 is being inserted into housing 34 through socket opening 56, spring 98 is cammed inwardly by the lower surface of opening 56 into groove 100. Once groove 100 passes completely through socket opening 56, the forward end of spring 98 will spring outwardly and abut the rear face 54a of socket means 54, thereby preventing pin member 58 from falling back out of opening 56.
  • Abutment of spring 98 with rear face 54a of socket means 54 also limits forward movement of pin member 58 under influence of spring 94 to a proper advanced position wherein grooves 68 are positioned for engagement by rails 76 of locking member 7 4 . If it is necessary to disassemble the lock assembly, a suitable tool can be inserted through opening 84 to force spring 98 upwardly into groove 100 until pin member 58 has been advanced sufficiently for spring 98 to be held in its groove 100 by the lower surface of socket opening 56.

  • rails 76 are sized to project laterally outwardly from grooves 62 beyond the sides of opening 56 so that they may abut the rear face 54a of socket 54.
  • the rear-to-front force exerted on pin member 58 by compressed spring 94, or any other rear-to-front force which might be exerted on pin member 58 is transmitted through locking member 74 to socket 54, whereby pin member 58 is prevented from advancing from the position shown in Fig. 17.
  • further retraction of pin 58 rearwardly from the position of Fig. 1 7 is not a particular problem, it might be noted that such movement will be limited by abutment of tab 80 of lock member 74 with the edge of opening 8 4 in housing 34 and abutment of lock member 75 with guides 73.
  • the locking member 74 is latched into its lowered or locking position, as shown, by virtue of the fact that spring 90 underlies the top wall 35 of housing 34 adjacent opening 84. It should be noted that, when the lock member 7 4 is in its locking position, it lies generally flush with the upper extremity of housing 34, which in turn is generally flush with the top wall 12 of the construction component 10 (shown in Fig. 17 but broken away in other Figs. for clarity).
  • the head end of pin member 58 projects forwardly from the front face 54b of socket 54 only by a very small distance, generally comparable to that by which the lugs 102 project. As previously mentioned, this distance is not great enough to interfere with transport and other handling of the construction component 10 in the manner of a standard freight container.
  • a crowbar or other suitable tool is inserted into notch 84a in opening 84 in the top wall 35 of housing 34 of the upper male lock assembly 20.
  • the tool is used to force the upper end of spring 90 forward, until it dears the underside of the top housing wall and is forced under tab 80.
  • tab 80 can be pryed upwardly, thereby raising locking member 74 and the connected locking member 75 of the lower male lock assembly 20'.
  • Continued upward movement may be effected, either with the same of another toot, or by hand, once the upward movement has been started in the aforementioned manner.
  • pin member 58 When the locking members 74 and 75 have been raised a sufficient distance to clear their respective pin members 58 and 58', i.e. to their release positions (which are analogous to those shown in Figs. 13 and 14 for the female lock assemblies) pin member 58 will be urged outwardly by spring 94, and pin member 58' will likewise be urged outwardly by a similar compression spring (not shown) in pocket 92'. lf, for any reason, e.g.
  • housing 34' is identical to housing 34, and in part i cu- lar, has an opening (not shown) in its lower wall identical to opening 84 in the upper wall of housing 34, a similar technique may be used to force pin 58' outwardly or forwardly.
  • pin member 58 As the portion of pin 58 which, in its retracted position, is disposed in pocket 92, moves forwardly, spring 98 will automatically emerge from its groove 100 in the underside of pin member 58. Spring will engage rear face 54a of socket 5 4 when the pin member 58 is in its advanced position, i.e. with grooves 62 located well beyond front face 54b of socket 54 and with grooves 68 located just behind rear face 5 4 a. under influence of spring 94. Although spring 98 would not be sufficient to take high tensile loading, it will stop the movement of pin member 58 in the forward direction under the relatively low force exerted by spring 94, and temporarily hold the pin member 58 in that position until lock member 74 can be lowered to its locking position, as shown in Fig. 11. Pin member 58' has an identical spring - (not shown) which similarly stops the forward movement of pin member 58' at its advanced position.
  • locking member 74 When locking member 74 is lowered, as by striking it with a hammer, the connected locking member 75 will automatically be lowered therewith. Rails 76 of locking member 74 will enter grooves 68, and rails 77 of locking member 75 will enter analogous grooves in lower pin member 58'. Since locking member 7 4 is sandwiched between rear face 54a of socket 54 and the edge of upper housing wall 35 adjacent opening 84, and lock member 75 is sandwiched between socket 54' and guides 73, this position locks the pin members in their advanced positions.

  • the locking members 116 and 117 of the tandem female lock assemblies 22 and 22' will be raised to their release positions, as shown in Figs. 13 and 14, in the same manner as was done with the male lock assemblies. Then, with the male lock assemblies in the positions shown in Figs. 11 and 12, and the female lock assemblies in the positions shown in Figs. 13 and 14, the construction components on which these assemblies are carried are drawn toward each other, as by ropes or the like, so that pin members 58 and 58' enter socket openings 106 and 106', respectively.
  • the tapered areas 60 on the head end of pin member 58 help to gradually guide the pin member into the female socket opening 106.
  • tapered areas 1 10 likewise help to gradually guide pin member 58 into socket opening 106.
  • the same type action occurs in the lower lock assemblies 20' and 22'.
  • the upper lock member 116 may readily be fully lowered and engaged with its respective pin member. It is noted, in particular, that if the upper female lock member 116 were permitted to engage its respective pin member too soon, it could provide a pivot point which would increase the tendency of the lower edges of the lateral walls of the two construction components to splay thereby making it difficult to properly mate and lock the lower assemblies.
  • pin member 58 If a rear-to-front tensile force is exerted on pin member 58, e.g. if the construction component on which the female lock assembly 22 is carried tends to pull away from the construction component on which the male assembly 20 is carried, such force will be transmitted from the rear face 104a of socket 104 through locking member 118 to pin member 58, and from pin member 58 through male locking member 74, to male socket 54.
  • the shear bearing lugs 102 and 108 of the male and female lock assemblies are meshed. Because the shear bearing formations 102 and 108 project and receive in a generally front-rear directional mode with respect to pin member 58, they are capable of transmitting shear forces transverse to pin member 58 independently of that pin member.
  • This arrangement is chosen, especially for components to be used in constructing floating structures such as barges, because the vertical shear forces tend to be greater than the transverse horizontal shear forces.
  • the shear bearing formations arranged to take vertical loads substantially bear the forces involved in such cantilevered support, particularly since the lock assemblies are arranged in tandem pairs, until pilings can be installed in supporting relation to the temporarily cantilevered parts.
  • shear bearing formations which would transmit horizontal shear forces independently of the pin member.
  • shear bearing formations be arranged so as to transmit shear loads transverse to the pin member in a direction generally parallel to the path of reciprocation of the locking means, thus they should face generally in such direction.
  • the transverse vertical dimension of pin member 58 can be substantially smaller than its transverse horizontal dimension, since pin member 58 is relied upon to transmit - only horizontal shear loads (which are usually relatively low in the types of construction in question).
  • a given locking system comprising a male and female lock assembly, is capable of handling generally greater loads than were previously possible, without a corresponding increase in the overall size and weight of the pin members.
  • by minimizing the vertical thickness of pins 58 and 58' it is possible to maximize the distance between their centers of gravity, and thereby better resist hinging action of the connected components on a horizontal axis.
  • the locking system of the present invention is defined to positively prevent any substantial hinging, about a horizontal axis, as between adjacent connected components. This enables such components to be assembled into many types of structures which could not be properly formed with the articulated types of connections exemplified by certain prior art systems. Not only is it possible, with the present invention, to form more stable floating structures, such as bridges, drilling platforms, etc., but it is also possible to form non-floating structures such as land supported bridges and the like, even using the temporary cantilevering technique described above.

  • This differs from prior art arrangements in which a single plate-like socket (for a female assembly) or pin base (for a male assembly) was welded to the construction component.
  • the new arrangement provides a better force distribution, and in particular, provides a welded attachment at a position spaced from the socket means, where substantial forces are felt, thereby lessening the chance of failure of one type or another.

  • Each of the components 202 also has a well or throughway 214 extending vertically therethrough, i.e. through its top 206 and its bottom 208.
  • the longer sides 210 of components 202 each carry two pair of lock assemblies of the type described in detail hereinabove, more specifically, a vertically spaced pair of male lock assemblies, upper one of which are shown at 20, and a pair of vertically spaced female lock assemblies, upper ones of which are shown at 22.
  • Each of the male lock assemblies 20 lies directly across from a female lock assembly 22, and the spacing between the male and female lock assemblies on a given side 210 of the component is the same as the lateral spacing between pairs of lock assemblies on the general component 10.
  • each of the bearing spud well components 202 has one of its longer sides 210 connected to the end wall of a respective one of the general components 10 in the outermost span of the pier.
  • Elongate spuds in the form of pilings 216 extend through the wells 214 of respective components 202 and into load bearing relation with the bottom of the body of water over which the pier lies.
  • An interlocking means 218 similar to member 69 of the first embodiment, is installed in each well 214 to interlock the respective component 202 to the respective spud 216, so that the weight of components 202 and adjacent components to which they are attached is borne by the spuds 216.
  • spuds 216 might simply be pinned or welded to components 202. Therefore, members 218 have been shown only diagrammatically, and will not be described in detail herein.
  • Figs. 18-20 show only one span of bearing spud well components 202. It should be understood that, throughout the length of the pier or dock whose outer end is shown in the figures, spans of bearing spud well components 202 could be interconnected between spans of general components 1 0 to provide load bearing capacity at as many points as necessary along the length of the pier. As alternatives to, or in conjunction with such spans of bearing spud well components, and depending on the parameters of the pier or other structure, bearing spud well components 202 could be used at the outboard sides of the spans of general components 10.
  • a first span consisting of several of the general components 10, connected side by side, and with bearing spud well components 202 connected adjacent opposite ends of the span, would be formed.
  • the first span could be elevated to its desired height, supported at that height by the pilings passing through the bearing spud well components 202, and used as a starting point.
  • a second span consisting of components 10 connected side by side, and with bearing spud well components 202 at only one end thereof, could be assembled, emplaced adjacent one end of the first span by a crane or the like supported on that span, and then supported on the first span in cantilever fashion using the lock assemblies 20, 20', 22 and 22'. Pilings would then be placed in supporting relation with the end of the second span distal the first span, via the bearing spud well components, the crane would be advanced onto the second span, and assembly would continue in like manner until the entire structure was completed.
  • each span would preferably be pre-assembled from components floating on the body of water, by way of contrast to the embodiment of Figs. 1-7 in which the components to be connected side-by-side in a given span are supported individually on respective components of a previously constructed span, and then locked to one another side by side.
  • Holding spud well component 204 is virtually identical to the bearing spud well components 202, except that its well 220 need not be adapted to cooperate with an interlocking member to allow the vertical load of the component to be placed on the spud 222 which extends through well 220. Rather, the well 220 need only laterally retain or hold spud 222.
  • Spud 222 in turn extends through a hole 224 of a floating bumper member 226 and into the floor of the body of water therebelow.
  • spuds 222 laterally position bumper member 226 with respect to the pier and also laterally position the pier with respect to the floor of the body of water. Bumper 226 provides an appropriate abutment for vessels docking at the pier.
  • component 204 is identical to component 202, and in particular, includes the same number and arrangement of male and female lock assemblies 20, 20', 22 and 22', whereby it is connected to the outermost side of one of the general components 10.
  • a respective rake component 200 is connected to the outermost side 210 of each of the load bearing spud well components 202.
  • Each rake component 200 has a rectangular top 228 and four lateral sides lying perpendicular to top 228, more specifically, a pair of opposite longer sides 230 and a pair of shorter sides 232 and 234.
  • the bottom 236 of each of the rake components 200 is tapered or graduated, so that the rake component has a deep end adjacent side 234, of the same depth as the other components 10, 202 and 204, and a shallow end adjacent side 232, which forms the outermost extremity of the pier or dock.
  • the term "rake component” will generally refer to the types of components illustrated at 200 as well as to ramp-like components which are tapered even more to form a more nearly pointed shallow end.
  • each rake component 200 has a pair of vertically spaced male lock assemblies 20 and 20', and a pair of vertically spaced female lock assemblies 22 and 22'.
  • the vertical spacing of the lock assemblies in each such pair is the same as that between the components of the various tandem pairs described thus far, and the lateral spacing between the male and female components on side 234 is likewise similar to the lateral spacing between adjacent pairs of lock assemblies in the components described hereinabove.
  • each rake component 200 can be locked to a respective bearing spud well component 202 as illustrated.
  • the cantilever method of support can be used as the only method or permanent method of supporting a span of rake components at one end of a structure, as shown in Figs. 18-20.
  • the side 232 of the rake component 200 adjacent the shallow end thereof likewise carries a tandem pair of male lock assemblies 20 and 20' and a tandem pair of female lock assemblies 22 and 22'. Because of the shallow depth of the adjacent end of the rake component, the lock assemblies in each of the two pair carried on side 232, while still vertically spaced apart, are not spaced by as great a distance as the lock assemblies in the other pairs described thus far. This is not disadvantageous in the dock or pier structure, since rake components 200 usually either define a free end of such a structure, as shown, or are connected, shallow end to shallow end, with similar rake components.
  • a major use of the lock assemblies on side 232 of the rake component 200 is in connecting two such rake components together to form a transport assembly.
  • a preferred form of such a transport assembly is shown in Figs. 2 1 and 22. It can be seen that two rake components 200 have been connected together, with their sides 232 facing each other, utilizing the lock assemblies 20, 20', 22 and 22' on those sides.
  • each rake component 200 which is measured horizontally parallel to sides 232 and 234, e.g. adjacent top 228, is generally equal to the width of a standard freight container.
  • Figs. 23 and 24 show another transport assembly of two rake components which might be used, for example, if the rake components in question have their shallow ends equipped with some type of fitting or accoutrement, diagrammatically illustrated at 242, which protrudes horizontally from the shallow end, and thereby prevents the shallow ends of the two components from being directly connected together by their lock assemblies.
  • the - scheme of Figs. 23 and 24 could also be used where it is desired to handle, in the manner of a standard freight container, an assembly of two rake components, where the length of each such component is somewhat less than half the length of a standard freight container.
  • the transport assembly of Figs. 23 and 24 comprises two rake components 200', which are identical to components 200 except in size and except for the provision of fittings 242.
  • the two components 200' are placed with those sides 232' which lie adjacent their respective shallow ends, facing each other, but not abutting.
  • Sides 232' are connected by means of the male and female lock assemblies carried thereon, but rather than being directly connected, they are connected by spacers in the form of struts 244.
  • Each strut 24 4 has a pair of male lock assemblies 20 and 20' at one end thereof, and a pair of female lock assemblies 22 and 22' at the opposite end.
  • each strut 244 has one end connected to a pair of lock assemblies on one of the rake components 200', and the other end connected to a pair of lock assemblies on the other of the two rake components 200'.
  • each of the components 200' i.e. that dimension which is measured horizontally and parallel to sides 230', is less than half the length of a standard freight container, but greater than one-third the length of a standard freight container.
  • the length of the spacers or struts 244 is chosen so that the length of the complete transport assembly is generally equal to that of a standard freight container.
  • the first dimension, measured horizontally parallel to sides 232' and 234' has a maximum value (and in this case a constant value) approximately equal to the width of a standard freight container.
  • the transport assembly includes two rake components 200" which, except for length and manner of connection in the assembly, are identical to components 200.
  • the sides 232" of these modified components adjacent their shallow ends carry, toward one lateral edge, a clevis 246, and toward the other lateral edge, a tongue 248.
  • each tongue 248 can be received in the clevis 246 of the opposite component. Then, the tongues and clevises can be pinned together by pins 250, held in place in any suitable manner, as well known in the art.
  • pins 250 and the mating holes in tongues 248 and clevises 246 are square in transverse cross section. Suitable bracing members may be used to supplement the anti-pivoting effect of pins 250.
  • each component 200 measured horizontally and parallel to sides 232" and 234", has a maximum value approximately equal to the width of a standard freight container.
  • the second dimension of each component 200 measured horizontally and parallel to sides 230" has a maximum value, adjacent top 228", slightly less than half the length of a standard freight container.
  • a transport assembly comprised of spud well components.
  • the assembly illustrated is comprised of bearing spud well components 202.
  • similar assemblies could be formed utilizing holding spud well components 20 4 , or combinations of the two types of spud well components.
  • each component 202 which is measured horizontally and parallel to its longer sides 210, is equal to the width of a standard freight container.
  • Said sides 210 of the components are also the sides which carry the lock assemblies 20, 20', 22 and 22'.
  • an assembly can be built up to have gross dimensions generally corresponding to those of a standard freight container. It is particularly convenient to simply connect adjacent components together utilizing the same lock assemblies 20, 20', 22 and 22', which are used to connect the components to other components in construction jobs.
  • any male lock assemblies which are facing outwardly and unused in the transport assembly should have their pins placed in the retracted or low profile positions.
  • each of the components 202 is already generally in the form of a rectangular parallelepiped, such sizing permits the assembly to be formed without the need for spacers or the like.
  • each component could be made approximately one-fourth the length of a standard freight container, with four components being connected together to form each transport assembly.
  • the requirements for sizing can be generalized as follows.
  • Each such component must have a first horizontal dimension with a maximum value generally equal to C,/x, where C, is the width of a standard freight container, and x is less than or equal to 1. In other words, the first dimension of each component must be less than or equal to the width of the standard freight container.
  • x be an integer, and in most cases, that x be equal to 1.
  • Each component should have a second horizontal dimension, measured perpendicular to the first dimension, having a maximum value generally equal to C,/y, where C 2 is the length of a standard freight container, and y is less than 1, i.e. that the second dimension of the component be less than the length of a standard freight container. It is highly preferable that y be less than or equal to 2, so that at least two such components can be joined together in each transport assembly, and it is even more highly preferable that y be an integer, again to minimize the need for supplemental elements for the transport assembly, e.g. spacers.
  • each of the general components 10 can be shipped and handled as a single freight container, while the rake components 200 can be formed into transport assemblies by twos, and the spud well components 202 and 20 4 can be formed into transport assemblies by fives. Each such transport assembly is likewise shipped and handled in the manner of a standard freight container, but without the need for trying to place these components within actual freight containers.
