Definitions

  • This invention relates to method and apparatus for joining structural components generally and, in particular, to joining first and second structural components when the first component is a tubular type element having an inner wall surface defining an internal duct and an outer wall surface surrounding the internal duct.
  • tubular type components there are a number of applications where a tubular type component needs to be joined, connected or otherwise attached to another component.
  • vertical building modules use hollow vertical columns which must have their lower ends connected to a base.
  • tubular type components can be used as beams extending between the vertical columns, which again require joining methods and apparatus.
  • tubular type elements such as truck beds or trailers for semi -trailer trucks. If the tubular elements are formed from aluminum, then important weight reductions can be achieved which translate directly into increased payloads and improved profits.
  • pole assemblies for street and highway lighting, electric wire carriers, and for other vertical standard uses.
  • These poles may be made from many materials which are suitable for their intended application, e.g., steel, aluminum, industrial reinforced plastic, or other materials. Most are elongated and tubular. Aluminum is very popular because of its light weight and corrosion resistant qualities.
  • the most common method of attaching a tubular pole is to weld the lower end of the pole to a base plate which is then connected to an anchor structure.
  • welding will decrease the loading capacity by as much as 57 percent. Therefore, it is preferable to mechanically fasten the pole to a base plate to retain the yield strength and loading capacity.
  • a lighter pole can be used which will have the same loading capacity as a larger and more expensive pole which has been attached by welding, particularly since the quality of a weld can vary from piece to piece.
  • the most popular mechanical fastening method is to use a fixed size inner sleeve which the tubular pole fits over.
  • the inner sleeve may be previously attached to a base plate with provisions for attaching the base plate to an anchor means.
  • the problem with this method is in controlling the size tolerance of both the fixed size inner sleeve and the size tolerance of the internal duct, which must be very close. Unfortunately, in the manufacturing process the desired tolerance cannot be maintained without adding considerable expense to the process, and/or the discarding of out-of-tolerance parts.
  • the pole fit is loose and a hinge effect will occur. This not only reduces the initial load capacity, but permits additional reductions in capacity if the pole metal is fatigued with the pole motion as time passes. If the inner sleeve is too large and is jammed into the tube duct, a shear problem may occur. In any event, the stretching of the pole by an oversized inner sleeve will stress the pole, and may actually cause a rupture, hairline crack, or the like.
  • the engineering community has accepted the '885 invention as a viable option to "brittle-break" welded posts in high stress as well as normal applications.
  • This method and apparatus provides the only nonferrous post or standard that will meet the engineering requirements in Dade County, Florida, in the aftermath of Hurricane Andrew and the resulting new, tougher Dade County codes.
  • the '885 invention is the only approach that can meet all the elements in the demand for low maintenance, lower cost, and longer life. Further, the '885 invention is a deterrent to earthquake driven utility standard failures in areas such as California in the United States, and internationally in Japan and other areas with high earthquake probabilities.
  • first component may be a tubular wall forming an elongated tubular element having an inner wall surface extending along and defining an internal passageway or duct, and an outer wall surface surrounding the inner wall surface and the internal duct or passageway.
  • second component may be another structural component, an anchor means, a frame structure, a support element, or other element.
  • a first embodiment of a coupling device separate individual means and a sliding interlocked connection means for connecting individual tenons to a wall portion of a link module provide several advantages.
  • the tenon members are individually adjustable on the wall portion to give more flexibility in providing various intermeshing arrangements. Therefore, instead of having to manufacture several individual different link modules to obtain a variety of different intermeshing arrangements, one needs only to manufacture a standard wall porion and a standard type of tenon means, so that any intermesh can be provided by simply assembling tenon means and wall portions.
  • the key to this flexibility was the development of the sliding interlock connection between the tenon members and a wall portion, without the loss of strength and function.
  • the tenon means may be used on either wall end portion by simply detaching from one wall end, inverting, and reattaching to the other wall end.
  • the tenon means and the wall portion can be manufactured in any length or height. Different wall portions can be provided which, in combination with adjustable individual tenons, can be assembled to provide engaging contact support and mate with the interior or exterior surfaces of any type of tubular element, whether square, rectangular, polygonal, tapered or the like, examples of such tubular elements being disclosed in Patent '885, incorporated herein by reference.
  • the various new components of the new combination may be formed from metals, such as steel or aluminum, or from heavy duty and strong industrial reinforced plastics.
  • the components may be formed by machining, casting, or other such approaches.
  • the preferred material is aluminum, because of its light weight, corrosion resistance qualities, and excellent strength to weight ratio when extruded, with a guaranteed material strength as opposed to inconsistent strengths when casting, for example.
  • extrusion of the components enables cost reductions in the manufacturing process. For example, extrusion reduces die and mold costs by seventy percent. Still, further, production is faster. Lead times for the combination components shown herein are shorter than the lead times on a pole shaft itself.
  • the above-described individual tenon means can be used with coupling devices which can engage either inner or exterior support surfaces of components to be joined together.
  • each module of a plurality of modules in the coupling device includes a wall portion with wall end portions on each end.
  • the wall end portions of at least some of the modules have tenon wall means extending parallel to an axis of the coupling device, and at least some of the wall end portions have slot mortise means formed therein which extend parallel to an axis of the coupling device whereby when the modules are assembled into the coupling device the tenon wall means are received into corresponding slot mortise means.
  • each wall portion has a slot formed therein which opens inwardly toward the center of the coupling device and extends parallel to an axis of the coupling device, the other of the wall end portions having a slot formed therein which opens outwardly from the center of the coupling device and ends parallel to an axis of the coupling device.
  • Each slot has an outermost slot wall at the end of each wall portion which forms the tenon wall means, whereby when the modules are assembled together into a coupling device the tenon wall means on a wall end portion is received in a slot formed on a wall end portion of an adjacent module.
  • the slots advantageously have a width enabling a tenon wall to be moved therein to permit expansion or reduction of the size of the coupling device to engage support surfaces with all modules of the coupling device.
  • the tenon walls cooperate with slot walls to form guide ways to receive a means for securing the modules of the coupling device into a unitary structure.
  • the securing means may include rod means with screw threads formed on one end.
  • the rod means may have a configuration on the other end shaped to be engaged and captured by the tenon wall and slot sides, to prevent the rod means from rotating when a nut is tightened on the screw thread end.
  • the modules may have outer and inner wall surfaces configured to mate with inner and exterior wall surfaces, respectively.
  • the second embodiment is specifically designed so that the modules can be manufactured by an extrusion process in order to obtain all of the advantages set forth hereinbefore for extrusions.
  • the modules may be used with coupling devices which can engage either inner or exterior support surfaces of components to be joined together.
  • the method and apparatus of this invention can be used to join two tubular elements together to form a horizontal beam. Further, this method and apparatus can be used to joint two tubular elements to replace a broken tubular element by joining a tubular element to a tubular element still left in the ground with the top portion is broken off or is bent (and cut off). This avoids having to tear up streets, sidewalks, etc. to bury a new pole. Further, this can be used for repair of a broken tubular mast or the like without having to return to port or a ship yard for total mast replacement.
  • this invention is also directed to method and apparatus for joining first and second components to provide a stronger and more stable apparatus and method.
  • apparatus and method can be used to join a first component to a second component, such as a base anchor device or the like.
  • This apparatus and method can also be used to join first and second components when each has a passageway formed therein which opens to the exterior of the component, such as first and second tubular elements. Further, the apparatus and method can be used to join first and second components by engaging the exterior surfaces of the two components.
  • the key to this effort is to preferably use the improved coupling devices described herein, secure the modules thereof together into first and unitary structures, and then connecting the first and second unitary structures together, after the customized fit for each coupling device is obtained by module adjustment with the associated separate support surfaces of the component involved with each coupling device.
  • Such a method can be used for joining first and second components when at least one of the components may have a passageway formed therein with inner support surfaces extending along the length of and defining the passageway, and when at least one of the components may have an outer or exterior support surface extending around the exterior of that component.
  • N first plurality of modules is assembled into a first coupling device. At least one of the first plurality of modules is moved with respect to the other modules so that the first plurality of modules is in engaging and support contact with one f the support surfaces of the first and second components.
  • the modules of the first coupling device are secured into a first unitary structure when the modules are in the engaging and support contact with the said one of the support surfaces of the first and second components to prevent movement of those modules with respect to each other in response to changing load conditions and to maintain the modules and the first unitary structure in a customized exact fit in a stable engaging and support contact position with said one of the first and second components.
  • N second plurality of modules is assembled into a second coupling device. At least one of the second plurality of modules is moved with respect to the other modules so that the modules are in engaging and support contact with another of said support surfaces of the first and second components.
  • the modules of the second coupling device are secured into a second unitary structure when the modules are in said engaging and support contact with said other of the support surfaces of one of the first and second components to prevent movement of said modules with respect to each other in response to changing load conditions and to maintain said modules and said second unitary structure in a stable engaging and support position with said other support surfaces of said one of the first and second components.

  • the description of the tenon means 400(i), 402(i) use in an inverted fashion serves to underscore another advantage of the components, combination and method of this invention. That is, only one type of tenon means needs to be manufactured, but that type may be used in different positions simply by inverting the standard type tenon as required. This reduces manufacturing costs, saves time, requires storage and shipping of fewer types of tenons with less sorting required, etc. Yet, all of the configurations desired can still be assembled to perform the functions of this invention by selectively inverting and interlocking the standard tenon with wall end portions. This flexibility of the uniquely formed individual tenon means provides substantial advantages over the prior art.

Abstract

L'invention concerne un dispositif de couplage, dans lequel des éléments indépendants et un mécanisme de raccordement à emboîtement coulissant, permettant de raccorder des tenons à la paroi d'un module d'assemblage, présentent plusieurs avantages. Tout d'abord, les tenons peuvent être ajustés individuellement sur ladite paroi, permettant ainsi d'obtenir un dispositif d'imbrication plus flexible. Ainsi, au lieu d'avoir à fabriquer plusieurs modules d'assemblage indépendants pour obtenir différents dispositifs d'imbrication, il n'est plus nécessaire que de fabriquer une seule paroi standard et un seul type de tenons standard, de sorte que l'imbrication est possible simplement par assemblage des tenons et des parois. On a pu obtenir une telle flexibilité en développant le raccordement à emboîtement coulissant des tenons à la paroi, sans perte de résistance ou diminution de la facilité d'utilisation. On peut utiliser les tenons sur n'importe laquelle des extrémités des parois, simplement en les détachant de l'une de ces extrémités, puis en les retournant pour les fixer sur une autre extrémité. Dans une variante, un dispositif de couplage peut, conformément à cette invention, être pourvus de modules dont chacun présente une paroi pourvue d'extrémités. Les extrémités d'au moins une partie de ces modules comprennent des tenons qui s'étendent parallèlement à un axe du dispositif de couplage, des fentes à mortaise étant ménagées dans au moins une partie desdites extrémités, et ces fentes s'étendant parallèlement à un axe du dispositif de couplage. Ainsi, lorsque lesdits modules peuvent sont assemblés à l'intérieur de ce dispositif de couplage, les parois à tenons viennent s'insérer dans les fentes à mortaise correspondantes.
