Detailed Description
In order to make the invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
The invention provides a hinged end-connected groove-shaped bulkhead which is characterized by comprising a groove-shaped bulkhead 1, wherein the groove-shaped bulkhead 1 comprises groove-shaped bulkhead panels, groove-shaped bulkhead webs and groove-sealing inclined plates at two ends of the groove-shaped bulkhead; the left side and the right side of the groove-shaped bulkhead 1 are provided with small groove shapes 2, and the upper end and the lower end of the groove-shaped bulkhead 1 are provided with reinforcing rib plates, longitudinal girders and strong cross beams 3; the groove-shaped bulkhead 1 adopts a symmetrical groove shape, and groove-shaped structures are transited to a groove-shaped neutral shaft by groove-sealing inclined plates at two ends of the groove-shaped bulkhead 1 until the groove-sealing inclined plates form a straight line which is communicated back and forth at two ends of the groove-shaped bulkhead 1 and is welded with a deck 5 or an inner bottom 6 or other structures.
The groove-shaped transverse bulkhead 1 with two chamfered ends adopts a symmetrical groove shape and comprises a groove-shaped bulkhead panel, a groove-shaped bulkhead web and groove-sealing inclined plates at two ends of the groove-shaped bulkhead; at two ends of the groove-shaped bulkhead 1, the groove-sealing inclined plates comprise a first groove-sealing inclined plate 111 and a second groove-sealing inclined plate 121, the groove-shaped configuration is transited to a groove-shaped neutral shaft until the groove-sealing inclined plates respectively form a straight line which is communicated back and forth at two ends of the groove-shaped bulkhead and are welded with the deck 5 or the inner bottom 6 or other structures, and the groove-sealing inclined plates form an angle of 45 degrees with the deck 5 or the inner bottom 6 or other structures, and can also be other angles;
when the first groove sealing inclined plates 111 at the two ends of the groove-shaped bulkhead are welded with the deck 5 or the inner bottom 6 or other structures, if a direct welding mode is adopted (shown in the left side diagrams of fig. 5 to 7), full penetration welding is required, and the first welding node 41, the second welding node 42 and the third welding node 43 are welded, and the welding quality is noticed; when the first groove-sealing inclined plates 111 at the two ends of the groove-shaped bulkhead are welded with the deck 5 or the inner bottom 6 or other structures, if a connecting member 431 similar to the head part of a double-bulb flat steel ball is adopted as a transition structure for welding (shown in a right side diagram of fig. 5 to 7), the width of the double bulb and the height of a web plate thereof are required to be as small as possible, a fourth node 44, a fifth node 45 and a sixth node 46 are welded, and the welding positions of the groove-sealing inclined plates at the two ends of the groove-shaped bulkhead and the web plate of the double-bulb structure are filled with welding materials for transition; the double-ball head part and the inner bottom or the deck or other structures can be welded by deep fusion welding; the welding part of the groove-sealing inclined plates at the two ends of the groove-shaped bulkhead and the groove-shaped bulkhead does not need to be provided with roots, so that liquid accumulation is avoided. When the first groove sealing inclined plate 111 and the second groove sealing inclined plate 121 are welded with the deck 5 or the inner bottom 6 or other structures, full penetration welding is required, the welding quality is noticed, and no root needs to be left at the welding position of the groove sealing inclined plates and the groove-shaped bulkhead.
The two ends of the chamfered groove-shaped bulkhead 1 are in the form of small groove shapes 2 at two sides of the bulkhead, the small groove shapes 2 comprise a left groove shape I21 and a right groove shape II 22, so that the periphery of the groove-shaped bulkhead 1 is ensured to correspond to the reinforcing structure I31, and the reinforcing structure II 32 is positioned in the same plane. The groove depth of the small groove shape is half of the groove depth of other groove shapes, and the width of the small groove shape web plate and the width of the panel are not suitable to be too large so as to avoid the problems that the local stress is large at the boundary of the groove shape and the like.
Arranging a reinforcing rib plate, a longitudinal girder and a strong cross beam 3 corresponding to the groove-shaped transverse bulkhead 1; the reinforced rib plate, the longitudinal girders and the strong crossbeam 3 comprise a first reinforced structure 31 and a second reinforced structure 32, and the rib plate, the longitudinal girders and the strong crossbeam 3 which are reinforced corresponding to the groove-shaped transverse bulkhead are reinforced corresponding to the groove-shaped bulkhead among the deck, the double-layer bottom and the inner and outer shells. Because the two ends adopt the chamfered end parts and the two sides adopt the small groove shapes, the periphery is correspondingly reinforced and only used as a structure at most; the reinforcing structure corresponding to the channel-shaped transverse bulkhead deck refers to a discontinuously arranged flat steel or flat bulb steel or other similar small components for the transverse bulkhead, and is not two traditionally reinforced strong cross beams; the corresponding reinforcing structure of the inner shell and the outer shell of the groove-shaped bulkhead is a shipboard side rib plate; the corresponding reinforcing structure of the double-layer bottom of the groove-shaped bulkhead refers to a watertight solid rib plate or a longitudinal girder, and is not two rib plates and a crescent plate or two longitudinal girders and a crescent plate which are reinforced traditionally.
In summary, the hinged end-connected groove-shaped bulkhead is similar to a structure that the two ends of the bulkhead are 'chamfered', and is welded with a corresponding structure directly or in a transition form of double-bulb flat bulb steel, the groove-shaped bulkhead in a half-groove deep small groove form is adopted at the two sides of the bulkhead, the corner constraint at the two ends of the groove shape is released, so that the groove-shaped bulkhead is closer to the simple support constraint, and the groove shape resists various loads of the groove-shaped bulkhead. In the form development process, a large amount of coarse grids, fine grids and fatigue analysis work are completed to verify the safety of the novel structure, the calculation results all meet the standard requirements, and the novel structure has good mechanical properties.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
