摘要:
A method and apparatus for assembling a lattice work of transverse and longitudinal members wherein the longitudinal members are fed from a carriage by a guide and feeding means into recesses in the transverse members which are held by base members. The carriage, guide and feeding means and base members are all mounted on guide rails to insure proper alignment and to move the elements with respect to one another.

A watercraft includes at least one float, a first frame supported by the at least one float, and a main panel affixed across the first frame. The watercraft further includes a second frame affixed to the first frame rotatably about a first edge and a second panel affixed across the second frame. In an embodiment, the first edge includes a shared frame member belonging to both said the frame and the second frame. In an embodiment, the watercraft includes a third frame affixed to the first frame rotatably about a second edge distinct from the first edge and a third panel affixed across the third frame. In an embodiment, the watercraft includes a shade rotatably affixed to a shade support edge member of the second frame and a shade panel affixed across the shade frame. The shade frame includes a pair of shade frame edge members rotatably affixed to the shade support edge member of the second frame.
摘要:
A marine hull including a hull plate manufactured from metal, a set of longitudinal reinforcements and a set of transverse reinforcements, at least one longitudinal reinforcement of the set of longitudinal reinforcements being arranged between the hull plate and at least one transverse reinforcement of the set of transverse reinforcements, and being connected to an inside of the hull plate. The marine hull is characterized in that the hull plate has a thickness that is less than 10 mm, and that the at least one longitudinal reinforcement is manufactured from the same metal as the hull plate and comprises at least one resilient segment arranged to spring in the direction transverse to the thickness of the hull plate, and that the resilient segment is arranged to bottom upon a compression that is more than 10 mm and less than 50 mm.
摘要:
A center tank of cargo oil tanks of a tanker is supported by integral ring-shaped transverse webs at plural positions in the longitudinal direction of a tanker whereby the strength of the cargo oil tanks is increased, necessary blocks are simplified and the building time is shortened.
摘要:
Apparatus for assembling curved skin block frames of a hull, which comprises (1) sets of oppositely disposed devices for positioning slotted transverse reinforcing members which have a transverse member clamping mechanism for holding the transverse members near both ends thereof in such a manner that the slots of the transverse members face downwardly and so as to position several transverse members therebetween, a transverse member supporting stool, a mechanism for adjusting the oblique angles of the transverse members, and a mechanism for adjusting the positions of the elevational direction, longitudinal direction and transverse direction of the transverse members; and (2) a device for positioning longitudinal reinforcing members, which comprises a longitudinal member clamping device for carrying longitudinal members corresponding to the slots of the transverse members, positioned previously in tentative longitudinal member positions, so as to insert the longitudinal members from the underside of the transverse members into the slots thereof, a longitudinal member supporting stool, a mechanism for adjusting the oblique angle of the transverse direction of the longitudinal members, a mechanism for adjusting the oblique angle of the longitudinal direction of the longitudinal members, a mechanism for adjusting the position of the longitudinal direction by lifting the longitudinal members, and an assembly for carrying the longitudinal members from the tentative longitudinal member positions to the slot positions; and a method therefor.
