A method for constructing a bridge includes the steps of disposing a bridge form and a connected support structure over an area to be spanned by the bridge. Next, concrete is poured into the bridge form. Finally, the support structure is disconnected and removed from the bridge form. The bridge forms are carried or supported by beams positioned over the area to be spanned. The forms may be carried directly by the beams or by support assemblies suspended from the beams may carry the bridge forms. Trolleys may be used to position portions of the forms between or below the beams.

Methods for constructing a bridge utilizing in-situ forms supported by beams

A long-span structure formed in-situ and extending between supporting structures includes at least two form supports extending between the supporting structures. Each end of the form support includes a bearing plate coupled to the adjacent supporting structure. A plurality of form hangers frictionally engage the form supports, wherein each form hanger has upwardly extending hooks. A beam form is carried by the plurality of form hangers and extends the length of each form support. Each beam form has opposed side walls connected by a bottom to form a cavity. Each sidewall has a downwardly extending hook mating with the upwardly extending hooks. A deck is supported by the beam forms with the cavities remaining open. The concrete is receivable at least in the cavities to form the long-span structure.

A concrete pipe and methods for forming the same are presented by this invention. The pipe includes an inner and outer sleeve separated by a spacer ring which creates a void therebetween. Concrete is poured within this void to solidify the pipe structure. The spacer ring is formed by a plurality of interlocking ring forms which have nesting members to allow for the interconnection thereof. In an alternative embodiment, interlocking forms are employed to form both the inner and outer surface of the pipe. These alternative forms provide convex nesting numbers which form internal conduits between the inner and outer surfaces that accept reinforcing members or connection members to interlock the forms to one another. Concrete is then filled in these conduits and between the void of the inner and outer surfaces to solidify the pipe construction. Both embodiments may employ a plurality of elbow forms to form a bell-mouth which connects with the end of an adjacent pipe. Both of these constructions provide the advantage of longer length pipes thereby reducing the overall cost of installing a pipe network system. Additionally, a better seal is obtained by this construction which reduces the amount of silt and debris that can accumulate within the pipe, thereby enhancing the flow characteristics of the pipe.

Concrete pipes and methods for the manufacture thereof

A method and apparatus for erecting building structures is presented. A plurality of wall panels are interconnected with each other in an array by column connectors interposed therebetween. Wall caps are then placed upon top surface portions of the wall panels and column connectors. Floor panels are then joined to the wall caps, with the floor panel forms having cavities to form headers over supporting wall panels and purlins between supporting wall panels. Rebar is placed into selected wall panels, purlins, and headers. Concrete is then deposited into selected ones of the wall panels and over the floor forms, filling the purlin and header cavities. Subsequently, a new array of wall panels and column connectors is erected on top of the poured concrete and the process is repeated to erect subsequent stories of the building.

Method and apparatus for erecting building structures

A containment structure and a method for making such structure requires the implementation of a plurality of a minimum of building elements. A plurality of panels are interconnected by connector columns in stacked relationship to generate a dual walled shell, adapted to receive concrete between the inner and outer walls thereof. Rebar and other appropriate reinforcing material may be appropriately positioned before the concrete is poured. Additionally, before pouring of the concrete, the mating connections of the panels and column connectors are fused together by the passing of electrical current through conductors received within such elements at their points of interconnection. The rising temperature melts the material of which the panels and column connectors are fabricated, causing them to fuse together. In one embodiment of the invention, a foam barrier is provided on either side of the resultant concrete cylinder. The foam is later removed by mechanical or chemical techniques and replaced with lead to achieve a containment structure for radioactive waste.

Containment structure and method of making same

A method and apparatus for building bridges from one location to another, and in which the construction activity takes place primarily at such terminal locations. Forms are assembled at one of the locations, such forms establishing the characteristics of the bridge deck to be built. When the forms are completed, they are elevated and suspended upon cables passing between the two locations. The forms are then pulled from one location toward the other, sequentially engaging with previously built and positioned forms until an entire complement of such forms extends between the two locations. The forms are then filled with concrete and finished. The forms provide an exterior finished surface for the bridge structure.
