Abstract

A vessel pressure tank type solid floor is formed by pressing a steel board to be in a section shape with a Z shape and a reverse-Z shape alternate. The vessel pressure tank type solid floor has the good intensity and rigidity in the out-of-plane direction, so that on the condition of keeping the same intensity and rigidity as a traditional solid floor in the vertical direction, the thickness of the pressure tank type solid floor can be decreased by about 50% than that of the traditional solid floor, and stiffener materials and manufacturing and installing time are omitted; in this way, the vessel pressure tank type solid floor has the advantages of being low in cost, high in efficiency, capable of reducing the weight of a vessel and improving the effective loading capacity of the vessel, and the like.

Description

Ship pressure grooved solid floor

Technical field

The invention belongs to ship structure technical field, relate to a kind of ship pressure grooved floor.

Background technology

The solid floor of boats and ships is one of important transversary parts of hull, and opsition dependent segmentation can be described as bottom solid floor and topside solid floor.On the ship of bivalve, floor mainly plays the structure that connects outside plate and tank top plate, side plating and longitudinal bulkhead composition carrying transverse load, and solid floor bears compressive load in short transverse simultaneously, and water tight floor also will bear the hydraulic pressure load of vertical rib board plane.

An Ge classification society rule regulation, boats and ships must arrange solid floor in rib position, 3 ~ 5, interval, the solid floor height of spitkit ship is less, it is generally plane steel plate structure, without stiffener structure, the solid floor height of big-and-middle-sized boats and ships is higher, the highest over 2 meters, by code requirement solid floor, surpass certain altitude stiffener must be set at a certain distance, oblique one-tenth free end can be cut in the solid floor stiffener two ends of medium-sized boats and ships, large ship is generally longitudinal framing double hull configuration, solid floor must arrange stiffener at every vertical bone place, stiffener end and the welding of vertical bone and cross section should be transition structure, avoiding structural mutation to produce stress concentrates.

Plane solid floor thickness plate or that establish stiffener is generally got the millesimal of its height, but is not less than 8mm, also needn't be greater than 15mm.

Traditional solid floor is because thickness of slab is thicker, the solid floor of big-and-middle-sized boats and ships also will be installed welding stiffener, therefore on the one hand structural weight is larger, more during the Welder of stiffener on the other hand, and the precision of solid floor and planarization is a greater impact because of the uncertainty of welding deformation.

Summary of the invention

More in order to overcome traditional plate solid floor and to establish the materials of solid floor of stiffener, and manufacture the many shortcomings of the operations such as field weld polishing of processing, the utility model provides a kind of indent type solid floor.

It is that to adopt indent type solid floor to replace traditional plate shaped or add the plane solid floor of stiffener that the utility model solve the technical problem adopted technical scheme, indent type solid floor is that steel plate die mould is become to be " Z-shaped " and " anti-Z-shaped " alternate cross sectional shape, and itself has good strength and stiffness in out-of-plane direction.Press that the position of grooved solid floor and hull longitudinal is different two kinds of forms, the taper bracket that must add traditional form of the Z-shaped web position alignment ship longitudinal bone of indent type solid floor, claims A type indent solid floor; What ship longitudinal bone passed from centre, groove position needn't add traditional form taper bracket, but need add, belongs to vertical bone benefit plate novel, integral form, claims Type B indent solid floor.The Z-shaped web position of A type indent solid floor is vertical with floor plane is 90 °, and the Z-shaped web of Type B indent solid floor position can be not vertical with floor plane, and angle is 90 ° ~ 135 °; Indent floor pros and cons groove width can be consistent, also can be inconsistent, specifically according to depth of floor, thickness and load situation, determine.

The beneficial effects of the utility model are, because indent type solid floor cross section is " Z-shaped " and " anti-Z-shaped " alternate shape, significantly improve the strength and stiffness of vertical plane surface direction, therefore keeping with dull and stereotyped solid floor or the plane solid floor that adds stiffener in the vertical direction under identical strength and stiffness condition of equivalent, the comparable traditional solid floor of the thickness of indent type solid floor reduces approximately 50%, and has saved stiffener materials and fabrication and installation man-hours; Therefore have cost low, efficiency is high, alleviates boats and ships deadweight, improves the multiple advantages such as boats and ships efficient loading amount.

The utility model can be widely used in big-and-middle-sized discharge type ships that transport.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail.

Accompanying drawing 1 ~ accompanying drawing 4 is traditional solid floor structures, is convenient to the utility model and contrasts with it.

Embodiment mono-

Referring to Fig. 5 to Fig. 8, A type indent solid floor, comprises A type indent shape solid floor 8.

It is characterized in that welding mutually with base plate 1 below of A type indent solid floor 8, weld mutually with tank top plate 2 top, welds mutually with stringers 7; Vertical bone 4, through indent solid floor, is indulged " Z " web position of bone 4 webs alignment A type indent solid floors 8, and at solid floor both sides welding equipment conventional transition bracket.A type indent type solid floor 8 two sides groove width a and groove width b can equate, also can be unequal, and " Z " position web at its vertical bone place is vertical with floor plane, and all the other " Z " webs can be vertical with floor plane, also can out of plumb.

Embodiment bis-

Referring to Fig. 9 ~ Figure 12, Type B indent shape solid floor, comprises the vertical bone benefit of Type B indent shape solid floor 9 and integral type plate 10.

It is characterized in that welding mutually with base plate 1 below of Type B indent type solid floor 9, weld mutually with tank top plate 2 top, welds mutually with stringers 7; Vertical bone 4 is through indent type solid floor, and vertical bone 4 is positioned at the notch middle part of Type B indent type solid floor 9, and the vertical bone of integral type is mended plate 10 and vertical bone, Type B indent type solid floor 9, base plate 1 or tank top plate 2 welding.Type B indent type solid floor 9 two sides groove width a and groove width b can equate, also can be unequal, and its " Z " position web is vertical with floor plane, also can out of plumb, angle γ is 90 ° ~ 135 °.
