Process for producing a connecting construction unit, such as a quay, container or platform, without the use of docks. The first step involves erecting when floating on the sea a rigid raft comprised of floating elements. A construction section is formed on the raft while the latter serves as a permanent under side of the construction section. The construction section has downwardly extending portions comprising connecting portions between the floating elements which are produced using the elements as formwork. The elements have at least two vertical slots which intersect to form a cross or star as a result of the elements being tightened together, the slots being brought into alignment with similar slots of neighboring elements. The elements are subsequently provided or formed with the connecting portions in an upper portion of the slots. The process can also be used for producing a submersible construction unit adapted to rest on, for example, the bottom of the sea. This process involves erecting a rigid raft having a bottom curvature corresponding to the bottom of the sea at the position of use. A construction section is then formed on the raft and the resulting construction unit is submerged by adjustable weight loading to the use position with the under side resting against the sea bottom. The construction unit has downwardly extending portions composed of rigid, deformable material. The weight loading causes deformation of certain of these portion against minor irregularities on the sea bed.
A floatable construction unit comprising a raft and a construction section permanently united with said raft, said raft including a plurality of floatable construction elements having horizontally disposed and upwardly opening slots therein, and an annular stiffener member surrounding associated slot defining portions of adjacent elements and coupling said elements together in mutually abutting relation with slots in adjacent elements in lateral communication with each other, said slots in said elements cooperating to define at least two horizontally disposed and upwardly opening form slots laterally intersecting in crossing relation, said construction section being disposed within said form slots.
A floatable construction unit comprising a raft and a construction section permanently united with said raft, said raft including a plurality of floatable blocks, each of said blocks having horizontally disposed top and bottom surfaces and vertically disposed side faces in abutting engagement with side faces of adjacent blocks, each of said blocks having a horizontally disposed base portion and a plurality of integral upwardly projecting vertical portions, said vertical portions and said base portion of each of said blocks defining horizontally disposed and upwardly opening slots therein, and an annular stiffener member surrounding the vertical portions of said adjacent blocks and coupling said adjacent blocks together in mutually abutting relation with said slots therein in lateral communication with each other, said slots in said adjacent blocks cooperating to define at least two horizontally disposed and upwardly opening form slots intersecting in crossing relation, said construction section being disposed within said form slots.
In a floatable construction unit a raft comprising a plurality of floatable construction elements having horizontally disposed and upwardly opening slots therein, and an annular stiffener member surrounding associated slot defining portions of adjacent elements and coupling said elements together in mutually abutting relation with slots in adjacent elements in lateral communication with each other, said slots in said elements cooperating to define at least two horizontally disposed and upwardly opening form slots laterally intersecting in crossing relation.
In a floatable construction unit a construction element consisting of a block of floatable material having horizontally disposed top and bottom surfaces and vertically disposed side faces for abutting engagement with side faces of other blocks of like kind in a formwork, said block including a horizontally disposed base portion and integral vertical portions projecting upwardly from said base portion, said block having an integral central stem projecting upwardly from said base portion and terminating below said top surface, said vertical portions, said base portion and said stem portion defining a plurality of slots, each of said slots extending transversely of said block and opening upwardly through said top surface and laterally outwardly through side faces of said block, each of said slots having an upper portion extending transversely through said block, the upper portions of said slots intersecting in a central region of said block above said central stem, each of said slots having a lower portion extending inwardly to said stem and terminating at said stem.
In a floatable construction unit a construction element consisting of a block of floatable material having horizontally disposed top and bottom surfaces and vertically disposed side faces for abutting engagement with side faces of other blocks of like kind in a formwork, said block including a horizontally disposed base portion, mutually spaced integral vertical portions projecting upwardly from said base portion, and outer wall portions projecting upwardly from said base portion and integrally connected to adjacent vertical portions, said vertical portions, said base portion and said outer wall portions defining a plurality of slots, said slots extending transversely of said block and intersecting in a central region of said block, each of said slots having an upper portion opening upwardly through said top surface and laterally outwardly through side faces of said block, each of said slots having a lower portion wholly disposed and terminating within said block, said lower portion being limited endwise by associated outer wall portions.
