Description
Technical field
The present invention relates to shipbuilding, it is related specifically to be assemblied in assembly method on steel plate and special in flat-bulb steel
Anti-tipping apparatus.
Background technology
During ship and offshore engineering, often use flat-bulb steel and be used as aggregate and play invigoration effect.It is special
It is not that, with the construction that goes into operation of high added value ship, substantial amounts of aggregate and reinforcement all employ flat-bulb steel structure and apply new at these
In ship type.In concrete application, typically the web of flat-bulb steel is vertically welded on the steel flat board of bulk, during this first
Flat-bulb steel is assembled to the position that is welded and fixed of steel plate, is welded and fixed again after turning to prepare and mutually should determine that position, so that
One or more flat-bulb steel and steel flat board are constituted into one.
In the prior art, flat-bulb steel is assembled and is welded and fixed together with steel flat board, often take following behaviour
Make flow：
The first step, is first placed into construction area by steel flat board, and on steel flat board that the fixed position line of flat-bulb steel is true
It is fixed；
Second step, flat-bulb steel is hung be pulled to construction area with crane gears such as cranes, and flat-bulb steel lentamente is placed into steel
Corresponding fixed position on flat board；
3rd step, at the two ends of flat-bulb steel and middle part welding diagonal brace to play a part of to prevent from toppling over and shift position, should
Diagonal brace one end is weldingly fixed on the bulb of flat-bulb steel, and the other end is weldingly fixed on steel flat board, and is adjusted as needed
Whole setting, to ensure fixed precision；
4th step, spot weld operation is carried out in the contact site of flat-bulb steel and steel flat board, is first tentatively fixed, and it is qualified to detect
Remove above-mentioned diagonal brace afterwards, reaffirm it is errorless after be further welded and fixed；
5th step, the dregs left during polishing removal diagonal brace operation and burr etc., it is ensured that smooth indeformable.
Above-mentioned flat-bulb steel has following not enough in the specific implementation with the assembling mode and used frock of steel flat board：
1. assembly manipulation is complicated and is difficult to ensure that precision, due to needing the equipment such as construction manual control crane to put on right position
To be assembled so that flat-bulb steel is placed into cumbersome complexity during steel flat board, and it is difficult to effectively to carry out position to ajust so that apply
Work is complicated slow and is difficult to ensure that precision.
2. welding sequence is cumbersome and maloperation easily occurs, and it is flat to ensure ball to weld diagonal brace again after being put on right position due to needs
Steel position correctly occurs without topples over and displacement so that the welding sequence complexity of diagonal brace is cumbersome, is difficult to effectively carry out once after welding
Adjustment, it is necessary to remove diagonal brace and weld again again so that operation easily error, causes whole work progress to be made slow progress, or even whole
The fixed effect of body.
3. the use consumption of diagonal brace is big and is difficult to recycle again, needs two ends to be respectively welded when being used due to diagonal brace
Flat-bulb steel and steel flat board on, dismounting need destruction pad could complete, be bound to scar need polishing, additionally, due to whole
Substantial amounts of erection welding is needed on body ship, the consumption of diagonal brace certainly will be caused big, and be difficult to effectively reuse.
The content of the invention
