Abstract

The utility model relates to a shipping solid rib plate buckling-restrained rib, wherein a solid rib plate is provided with an opening, the upper and lower edges of the opening are provided with buckling-restrained ribs; and generally, the solid rib plate is provided with four waist-round holes in the transverse direction, the height of the waist-round holes is 800mm, the width is 600mm, the upper and lower edges of the two waist-round holes on the right side are provided with buckling-restrained ribs, and the buckling-restrained ribs are welded on the upper and lower edges. In the utility model, the buckling-restrained ribs are firstly welded on the upper and lower edges of the rib plate opening in advance, thus effectively preventing the deformation of the rib plate during construction process.

Description

A kind of boats and ships solid floor is prevented the flexing muscle

Technical field

The utility model relates to the shipbuilding equipment technical field, and concrete relating to is applied in the anti-flexing muscle on the boats and ships solid floor.

Background technology

According to the SOLAS requirements of convention, 20000 gross tons that on January 1st, 2006 built later on and above bulge carrier, need satisfy the requirement of PMA, on floor, to be provided with the perforate of 600x800, usually vertical the placement, and existing regulation and stipulation, satisfy at solid floor thickness under the situation of standard, when its perforate height less than the double bottom height 50% the time, can strengthen, but in recent years, because the technological level in each shipbuilding yard is not quite similar, under segmentation is improperly stacked and closed up in proper order greatly, can cause the bending deformation of floor tapping.

In the manufacture process of boats and ships because improper assembling and close up the order caused floor tapping bending deformation problem.As shown in Figure 1, it is a typical solid floor section of certain bulge carrier, the height of its double bottom is 1780mm, perforate 1 ' and highly be 800mm, the solid floor height less than 1/2, can not strengthen normally handling, but aforementionedly mention, under mode of construction improperly, bring the consequence of distortion may for the solid floor tapping, below we can simply analyze, why can produce phenomenon like this.Suppose when closing up greatly, double bottom segmentation major part is closed up and is finished, large batch of again close up topside and top side tank segmentation with it this moment, if do not take adequate measures to increase transverse strength, if it is unreasonable again that docking block is arranged, like this, two sides of a ship at boats and ships, will certainly produce a pair of being applied to and divide additional bending moment on the solid floor near amidships, be similar to the hogging condition of hull beam, so, the first half of solid floor will tension, and the lower part pressurized very easily causes the bending deformation of solid floor perforate lower edge.

The utility model content

Technical problem to be solved in the utility model is, overcome problems of the prior art, provide a kind of boats and ships solid floor to prevent the flexing muscle, this anti-flexing muscle can actv. prevents to assemble improperly and close up the problem of the caused floor tapping bending deformation of order.

In order to address the above problem the technical solution of the utility model is such:

A kind of boats and ships solid floor is prevented the flexing muscle, and described solid floor is provided with perforate, and lower edge is provided with anti-flexing muscle in the described perforate.

General has four oval holes in a lateral direction at solid floor, and the height in oval hole is 800mm, and width is 600mm, is being respectively arranged with an anti-flexing muscle near lower edge on two oval holes on right side.By adopting the welding manner of two-sided continuous fillet weld, described anti-flexing muscle is welded on securely near on the lower edge on two oval holes on right side.

The length of described anti-flexing muscle equals a spacing of longitudinals of boats and ships in its region, highly is 150mm, and thickness is 10mm, and cut tiltedly at two ends.

Beneficial effect, the utility model are to prevent that in advance the flexing muscle is welded on the last lower edge of floor perforate, can prevent to deform in manufacture process at floor by actv., and the utility model operability is good, and effect is obvious, has very strong practicality.

Description of drawings

Describe the utility model in detail below in conjunction with the drawings and specific embodiments;

Fig. 1 is existing solid floor structural representation;

Fig. 2 is a solid floor structural representation described in the utility model.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Boats and ships are at little assembling stage, lower edge adds anti-flexing muscle in the floor perforate in advance, thus, satisfy at solid floor thickness under the situation of standard, no matter be in little assembling, for a short time close up, and even in close up greatly and close up the stage, the bending deformation that can not cause the floor tapping because of the improper of construction sequence, also controlled simultaneously the thickness of solid floor, avoid thickening, like this, we can say one in manufacture process, also reduced the shipbuilding cost when economizing on resources for the shipowner for country, two in long-term from now on operation process, more freights because of alleviating of boats and ships deadweight, for the shipowner brings direct considerable economic more.

Referring to Fig. 2

The structural profile of solid floor as shown in the figure, its be provided with in a lateral direction 1, four perforate of four perforates 1 evenly size, arrange that evenly perforate 1 is the oval hole, the height in oval hole is 800mm, width is 600mm.And the height of its double bottom is 1780mm.

In order to prevent distortion, lower edge adds anti-flexing muscle 2 in two perforates 1 of the solid floor rightmost side in advance, by adopting the welding manner of two-sided continuous fillet weld, flexing muscle 2 is welded on the last lower edge of perforate 1, and suitably strengthen the leg height at flexing muscle 2 two ends, to improve its anti-intensity.Usually be t4 to thickness only, two panels of t5 are strengthened.The one additional bending moment maximum that herein is subjected to, two come herein thickness also is minimum in all solid floor panels usually, because in order to improve the resistance to shear of double bottom, thickness is t1, t2, the panel of t3 generally all can suitably be thickeied after FEM (finite element) calculation, has possessed the ability of certain anti-flexing, mode by welding is connected it with solid floor again, in order to make in manufacture process, the workman carries out assembling and positioning to it as far as possible convenient and simplely, and oblique processing is often cut at its two ends.

In order to make anti-flexing muscle 2 reach due effect, anti-flexing muscle generally adopts band steel, and the length of described anti-flexing muscle equals a spacing of longitudinals in its region, highly is 150mm, and thickness is 10mm.

More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
