Description

Technical Field

[0001] The utility model relates to the technical field of ship accessories, in particular to a marine air vent bracket structure. Background Art

[0002] In order to meet the stress bearing requirements of IACS (International Association of Classification Societies) for the outfitting parts in the bow area of ​​1 / 4 of the ship's length, the vent pipes and ventilation heads in this area need to be designed and evenly installed with multiple support brackets for reinforcement. Due to the numerous pipe systems in the deck area, the arrangement of traditional vent pipe brackets can easily affect the direction or arrangement of the pipelines, and the brackets may tear due to excessive stress on the vent pipes. Based on this, the utility model proposes a marine vent pipe bracket structure to solve the problem that the vent pipe brackets can easily affect the pipeline arrangement and withstand poor stress. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a marine vent pipe bracket structure. Compared with the previous bevel edge design, the outer arc edge of the far tube and the inner arc edge of the near tube arranged in reverse are beneficial to the arrangement of the peripheral pipelines outside the bracket body. At the same time, the arc design is more convenient for stress release. When the vent pipe is subjected to a large load, the bracket can effectively bear and release the stress.

[0004] The marine ventilating pipe bracket structure in the present solution includes at least three bracket bodies, each of which is distributed in a circular shape and abuts against the outer wall of the ventilating pipe, and the bottom of the bracket body is connected to the deck surface, wherein the bracket body has a straight edge of the pipe in contact with the outer wall of the ventilating pipe, a straight bottom edge in contact with the deck surface, and an inner arc edge near the pipe and an outer arc edge far from the pipe, the inner arc edge near the pipe is located between the straight edge of the pipe and the straight bottom edge to adapt to the shape of the bottom end of the ventilating pipe, and the outer arc edge far from the pipe is located on the back side of the inner arc edge near the pipe. In the present solution, a plurality of bracket bodies are arranged around the outer wall of the ventilating pipe, which can be used for supporting and strengthening the ventilating pipe. At the same time, the outer arc edge of the far pipe and the inner arc edge of the near pipe arranged in the back are compared with the bevel design, which is conducive to the arrangement of the peripheral pipelines outside the bracket body. At the same time, the arc design is more convenient for stress release. When the ventilating pipe is subjected to a large load, the bracket can effectively withstand and release stress without the bevel being torn.

[0005] The technical solution further defined in the utility model is:

[0006] Furthermore, the inner arc edge near the tube is composed of a curved segment at the upper end and a straight segment at the lower end to adapt to the end shape of the connection between the air vent and the deck. At the same time, the curved segment also improves the overall stability of the inner arc edge near the tube, which is beneficial to the release of stress.

[0007] Furthermore, the outer arc edge of the distal tube is an inwardly concave arc, and the radius of the arc is twice the height of the bracket body.

[0008] Furthermore, the toggle plate body has a height of 460 mm, a length of 200 mm, and a thickness of 8 mm.

[0009] Furthermore, the bracket body comprises Q235 steel.

[0010] Furthermore, there are three toggle plate bodies in total and they are evenly and symmetrically distributed on the outer wall of the air permeable tube.

[0011] The beneficial effects of the utility model are as follows: the utility model uses a plurality of bracket bodies to surround the outer wall of the air vent pipe, which can be used to support and strengthen the air vent pipe. At the same time, the outer arc edge of the far pipe and the inner arc edge of the near pipe arranged in reverse are not only beneficial to the arrangement of the peripheral pipelines outside the bracket body, but the arc-shaped design is also convenient for stress release. When the air vent pipe is subjected to a large load, the bracket can effectively bear and release stress, and the bevel edge will not be torn; the concave arc edge design of the bracket body of the utility model also reduces the cross-sectional area, thereby reducing the weight accordingly and reducing part of the construction cost.

[0016] This embodiment provides a marine vent pipe bracket structure, such as Figure 1 As shown, the vent pipe 20 is vertically installed on the deck surface 30, and three bracket bodies 10 made of Q235 steel are evenly distributed and installed on the circumferential outer wall of the vent pipe 20. The bracket body 10 has a straight edge 11 in contact with the outer wall of the vent pipe 20, a bottom straight edge 14 in contact with the deck surface 30, and a near-tube inner arc edge 13 and a far-tube outer arc edge 12. The near-tube inner arc edge 13 is located between the straight edge 11 and the bottom straight edge 14 to adapt to the shape of the bottom end of the vent pipe 20, and the far-tube outer arc edge 12 is located on the back side of the near-tube inner arc edge 13. The near-tube inner arc edge 13 in this embodiment is composed of a curved segment at the upper end and a straight segment at the lower end, and the far-tube outer arc edge 12 is a circular arc, and the radius of the circular arc is twice the height of the bracket body 10.

[0017] Specifically, the marine vent pipe bracket structure of this embodiment can be widely used for supporting and reinforcing various vent pipes and vent pipe heads, and can also be used for bracket reinforcement of other outfitting parts. The manufacturing and installation process of the bracket body 10 is as follows: according to the size of the vent pipe and IACS requirements, the appropriate length L and height H are designed, and the minimum wall thickness t is 8mm (see Figure 2 ), first select the appropriate length and height dimensions, draw the bracket pattern according to the arc radius of about 2 times the height dimension, and then cut the material by number. Each vent pipe 20 is installed with no less than 3 brackets. All brackets are made by number cutting, and the appearance is beautiful. The bracket body 10 of this embodiment is smaller in size and lighter in weight than the traditional bracket, which is convenient for arranging the pipelines around the vent pipe. Take a bracket with a height of 460mm and a length of 200mm as an example (see Figure 3 ), the cross-sectional area of ​​the new bracket body 10 is reduced by 18.72% compared with the traditional bracket, and its weight is reduced by 18.72% accordingly. The large-scale use of the new bracket body 10 can effectively reduce the construction cost; the arc transition saves space compared with the bevel transition, and the maximum part of the arc is about 30mm recessed compared with the bevel, which is more convenient for the arrangement of surrounding pipelines; the arc design of the new bracket body 10 is more convenient for stress release. When the vent pipe 20 is subjected to a large load, the bracket can effectively bear and release stress, and the bevel will not be cracked.

[0018] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
