14- Claims.
My present invention relates to structures for hulls of ships, airplanes, containers, tanks and the like.
It is an object of my present invention to provide beam structures which are especially Well adapted to stiffen the hull of ships, airplanes, containers, tanks and the like.
It is a further object of my present invention to combine the above beam structures with suitably spaced transversal supporting frames, bulkheads or similar means, and to form thus a monolithic spatial body of extraordinary rigidity in transversal, lateral, and also longitudinal direction.
Still a further object of my invention is to provide for the above purposes beam grid structures composed of a series of beam grid panels monolithically secured to each other along their edges and supported partly by adjacent beam grid panels and partly by the above mentioned transversal supporting frame structures. A further object of my invention is to provide a beam grid structure being particularly well adapted to be used as monolithic stiffening structural frame for concrete ships, barges and other containers for fiuid or the like.
Still another object of my present invention consists of hulls for ships, airplanes, containers, tanks and the like, made of steel, light metal or concrete slabs which are stiffened and reinforced by beam grid structures of the type proposed.
With the above objects in View, my present invention mainly consists of a monolithic structural body or hull for ships, airplanes, containers, tanks and the like, comprising a series of mainly four-sided rectangular beam grid panels, each of which is supported at two opposite edges by transversal frames or bulkheads, and at the other two edges by adjoining beam grid panels inclined to the same; each individual beam grid panel is composed of two groups of parallel beams being arranged diagonally to the panel edges and connected to each other at their intersection points. Furthermore, these beam grid panels are preferably arranged in such a manner that two opposite edges of each panel are parallel and two opposite edges normal to thelongitudinal axis of the hull, and that each panel is monolithically connected along these edges to adjacent panels. The longitudinal edges of these panels are supported by adjacent .panels, while bulkheads or other cross frames serve as supporting means for the transversal panel edges. A preferred embodiment of my invention consists of a hull structure having a series of longitudinal rectangular faces contacting each other along ridge-like edges being parallel to the longitudinal hull axis; each of these faces is formed by a series of rectangular beam grid panels of the above described type; the subdivision into panels is achieved by means of bulkheads or other transversal frames, the planes of which are normal to the above mentioned ridge-like edges; along the transversal panel edges formed by these transversal frames, the panels are monolithically secured to adjacent beam grid panels of the same hull face and supported by these transversely arranged frames.
These transversal frames, such as bulkheads or other structures, preferably consist of beam grids which are arranged spaced from each other normal to the longitudinal axis of the hull and secured to the beam grid panels along their transversal edges.
When the new stiffening beam grid structure is used for airplanes, ships or barges, the squares formed by the intersecting beams of the grids are covered with steel, concrete or light-metal slabs forming a coherent hull. The novel features which I consider as characteristic for my invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings, in which:
Fig. 1 is a side view of a barge designed in accordance with my present invention, partly in section;
Fig. 2 is a top view of the barge shown in Fig. 1;
Fig. 3 is a longitudinal section through a part of the barge along line 3-3 of Fig. 2; I
Fig. 4 is a cross section through the barge along line 4-4 of Fig. 3;
Fig. 5 is another cross section along line 55 of Fig. 3;
Fig. 6 is a longitudinal section along line 6-5 of Fig. 4;
Fig. '7 is a similar longitudinal section along line l-'! of Fig. 5; and
Figs. 8 and 9 are two longitudinal sections through a modified beam grid structure corresponding to the sections shown in Figs. 6 and 7.
As shown in Figs. 1 and 2 and indicated by dotted lines, the barge body H is composed of a series of compartments l2, the construction of which is identical.
The hull is reinforced and stiffened by the beam grid structure shown in Figs. 3 to '7. The spaces between the beams are covered with slabs 13 forming the hull of the barge. In accordance l with the present invention, the beam grid structure is'composed-of a series of beam grid panels 14; each of these panels consists of two groups 15 and 16- of diagonally arranged beams; these beams are rigidly connected to each ether al; their points of intersection ll.
As shown in Figs. 4 and 5, the beam grid structure is shaped in such a manner as to form a series of longitudinal rectangular faces, namely, a bottom face l8, atop face l9, and two faces 20 and 2| on each side of the barge.
Each of these faces l8, I9, 20, and 2! is composed of a series of consecutive beam grid panels 14 of the type described above. It must be noted that in all beam grid panels the distance between the single beams has to be equal; this makes it possible to connect the beams of the beam groups i5 and I6 at their ends 22 with the ends 23 of corresponding beams of adjacent beam grid panels. The thus connected beams form two groups of helical beam structures extending, as shown in Fig. 1, coaxially with the axis of the ship structure over the entire length of the ship hull.
I have found that in most cases it is preferable to provide besides the above described beam grid structure additional supporting structures normal to the axis of the hull; this supporting structure preferably consists of a supporting beam grid 24, preferably secured to the edges 26, i. e. to those edges of the beam grid panels which are normal to the ridge-like structure edges 25. These supporting structures are also provided with concrete slabs 21 forming thereby compartments, i. e. bulk heads in the interior of the ship or barge.
In some cases, it is advantageous to arrange along the edges of the beam grid panels edge beams 28 and 29 secured to the diagonal beams l5 and I6 of the panels.- In this event the edge beams 28 are forming the ridge-like structure edges 25, and the edge beams 29, form the panel edges 26 which are normal to the structure edges 25.
It should be noted that all beam grid panels l4 forming one of the faces l8, i9, 20, and 2|, must be of equal length in direction normal to the structure edges 25, i. e. the length of the edges 26 of these panels must be equal. Furthermore, it is also of importance to stress the fact that the length of all-beam grid panels I4 arranged between two consecutive supporting beam grids 24 must be identical, too; only in this case is it possible to arrange these supporting beam grids in the required manner and to form bulk heads in the interior of the barge.
The modified structure shown in Figs. 8 and 9 differs only slightly from the above described one: In the above described embodiment the distribution of the intersecting points between diagonal and edge beams is symmetrical only along the structure edges 25, and asymmetrical along the edges 26, whereas in the embodiment shown in Figs. 8 and 9 the distribution of intersecting points along opposite edges is entirely symmetrical, i. e. the intersecting points are arranged along opposite edges in the same way. In the latter case, diagonal beams of four adjacent beam grid panels are meeting in each corner of the panels and are there connected to each other.
It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of beam grid structures for ships, airplanes and the like diifering from the types described above.
While I have illustrated and described the invention as embodied in beam grid structures for ships, airplanes and the like, I do not intend to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of my invention.
Without further analysis, the foregoing will so fully reveal the gist of my invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalency of the following claims.
