Description
Technical Field
The invention relates to the technical field of ships, in particular to a diagonal bracing structure for a supporting bulkhead of a container ship.
Background
The platform and inner shell at the supporting bulkhead of the container ship are connected to reduce the stress concentration of direct cross, and a toggle plate is generally arranged at the joint of the platform and the inner shell. When the vessel is subjected to transverse water pressure, the stress level on the toggle plate is high and cracks are likely to develop at the toe end of the toggle plate.
In order to solve the problems, the conventional method is to make the size of the toggle plate large, locally insert the thickness of the transverse strong frame, the thickness of an inserted thick plate is often 2 times of that of a basic plate, and the transition of the plate thickness is required to be considered according to the specification, so that the problems of excessive structural reinforcement, more plate seams, difficulty in construction and the like are caused. For a wide container ship, the problems are more obvious, the method for enlarging the toggle plate is not suitable, the cabin wall needs to be locally increased, the structural strength needs to be increased, the stress of the toggle plate at the joint of the platform and the side is reduced, and the safety of the structure is ensured.
Disclosure of Invention
The technical problem to be solved by the invention is to overcome the defects in the prior art and provide a diagonal bracing structure for a supporting bulkhead of a container ship.
The invention solves the technical problems through the following technical scheme:
a diagonal bracing structure for a supporting bulkhead of a container ship is arranged at the joint of a lower end platform and an inner shell in the container ship; the reinforced bulkhead is simultaneously and fixedly connected to the lower end platform and the inner shell; the reinforced bulkhead is provided with an oblique supporting part and hollow parts, and the hollow parts are arranged on two sides of the oblique supporting part; the upper end of the inclined supporting part is fixedly connected with the inner shell, and the lower end of the inclined supporting part is fixedly connected with the lower end platform; several reinforcing ribs are fixed on the diagonal portion.
The reinforced bulkhead is a rectangular plate, and two adjacent end edges of the reinforced bulkhead are fixedly connected to the lower end platform and the inner shell respectively.
The diagonal portion is distributed along a diagonal direction of the reinforced bulkhead.
One of the hollow parts is positioned among the lower end platform, the inner shell and the inclined strut part.
The reinforcing ribs are distributed along the length direction of the diagonal portion.
One of the reinforcing aggregates coincides with a diagonal of the reinforcing bulkhead.
The reinforcing bone materials are parallel to each other.
The number of the reinforced aggregates is 3.
A first toggle plate is arranged between the top of the reinforced bulkhead and the inner shell.
And a second toggle plate is arranged between the outer side end edge of the reinforced bulkhead and the lower end platform.
The invention has the beneficial effects that: according to the inclined supporting structure for the supporting bulkhead of the container ship, the bulkhead with the inclined supporting structure is arranged at the connecting part of the lower end platform and the inner shell in the container ship, so that the structural strength safety can be met, and the bearing capacity of the structure can be utilized to the greatest extent. The invention can reduce the weight increased by structure reinforcement, reduce structural plates and facilitate construction.
Drawings
FIG. 1 is a schematic structural diagram of a preferred embodiment of the present invention.
Detailed Description
The present invention will be more fully described in the following detailed description of the preferred embodiments thereof, taken together with the accompanying drawings.
As shown in fig. 1, a bracing structure for supporting bulkheads of a container ship is provided at the junction of a lower end platform 10 and an inner hull 20 in the container ship; it comprises a reinforced bulkhead 30, the reinforced bulkhead 30 being fixedly connected to both the lower platform 10 and the inner shell 20. In this embodiment, the reinforced bulkhead 30 is a rectangular plate, and two adjacent end edges of the reinforced bulkhead are respectively and fixedly connected to the lower end platform and the inner shell.
The reinforced bulkhead 30 has a diagonal support portion 31 and a hollowed-out portion 32.
The upper end of the inclined supporting portion 31 is fixed to the inner casing 20, and the lower end of the inclined supporting portion 31 is fixed to the lower stage 10. The diagonal-support portions 31 are distributed in the diagonal direction of the reinforced bulkhead.
Both sides of the inclined support portion 31 are provided with hollow portions 32. One of the hollow parts is positioned among the lower end platform, the inner shell and the inclined strut part.
Several reinforcing ribs 33 are fixed on the diagonal portion. The reinforcing ribs are distributed along the length direction of the diagonal portion. One of the reinforcing aggregates coincides with the diagonal of the reinforcing bulkhead.
The reinforcing bone materials are parallel to each other. Preferably, the number of the reinforced aggregates is 3.
A first toggle plate 41 is provided between the top of the reinforced bulkhead 30 and the inner shell 20. A second toggle plate 42 is provided between the outboard edge of the reinforced bulkhead 30 and the lower landing 10. The structural strength is further improved by providing the first toggle plate and the second toggle plate.
The inclined strut structure of the supporting bulkhead of the container ship optimizes the integral reinforcing structure of the conventional transverse bulkhead into an inclined strut structure form, the inclined strut structure keeps the part of the structure for concentrated bearing along the diagonal direction of the step frame of the cargo hold, and other non-bearing areas are in an open hole form.
According to the inclined bracing structure for the supporting bulkhead of the container ship, the bulkhead with the inclined bracing structure is arranged at the joint of the lower end platform and the inner shell in the container ship, so that the structural strength safety can be met, and the bearing capacity of the structure can be utilized to the greatest extent. The invention can reduce the weight increased by structure reinforcement, reduces structural plates, is convenient for construction, and is an optimized structural design.
While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and that the scope of the invention is defined by the appended claims. Various changes or modifications to these embodiments may be made by those skilled in the art without departing from the principle and spirit of this invention, and these changes and modifications are within the scope of this invention.
