Description

Technical Field

[0001] This invention belongs to the field of marine technology, and more specifically, relates to a ship bridge structure. This invention also relates to a method for installing a ship bridge structure. Background Technology

[0002] Ships typically have a bridge atop their superstructure, serving as the navigational area for the ship's crew. This fully enclosed space is surrounded by transparent windows or weatherproof doors. To ensure safe navigation, extension bridges are usually installed on both sides of the bridge, extending outwards from the weatherproof doors. These extension bridges provide visibility into the blind spots of the bridge, facilitating safe berthing or passage through narrow channels. The bridge extensions are usually open areas, with the compass deck extending outwards from the bridge to form a rain shelter. The outer edge of the rain shelter is rigidly supported by struts, and its shape matches that of the bridge extension, projecting trapezoidally from both sides. The top deck of the bridge is an open compass deck, typically designed as a gravity-drained arched beam (i.e., a drainage slope that is high in the middle and low on both sides). The water accumulation area formed above the bridge's extended canopy necessitates the installation of downpipes to discharge rainwater onto the bridge deck and further downwards through the bridge's drainage pipes. However, due to limitations imposed by the tubular supports and bulwark structure, the downpipes described in the background section are difficult to place on the line connecting the supports to the starboard compass bearing on the extended bridge, thus obstructing compass bearing observation. Furthermore, the steel downpipes cannot be reasonably concealed.

[0003] The prior art includes a technology entitled "A Vibration Reduction Structure for Superstructure of a Ro-Ro Ship" with publication (announcement) number "CN114919690B". This technology provides a vibration reduction structure for the superstructure of a Ro-Ro ship. The superstructure is located above the main deck of the Ro-Ro ship and is spaced apart from the main deck. The foremost end of the superstructure is located in the middle of the Ro-Ro ship and extends towards the stern. The superstructure includes a first deck, a second deck, a bridge deck, and a compass deck from bottom to top. Multiple vertical supports are provided between the first deck and the main deck of the Ro-Ro ship. The number of supports is even and they are arranged in two parallel groups along the length of the Ro-Ro ship and are symmetrical with respect to the transverse central axis of the Ro-Ro ship. The upper end of the support is fixedly connected to the lower end of the first deck and the lower end is fixedly connected to the main deck of the Ro-Ro ship. The superstructure layout and vibration reduction structure of this invention have the advantages of low wind resistance during ship operation, saving navigation energy consumption; effectively reducing vibration in the main driving and living areas of the superstructure, improving shipboard comfort; and increasing ship load capacity, resulting in excellent economic efficiency. This technology does not address the technical problems or solutions of this application. Summary of the Invention

Place vapor phase corrosion inhibitor on the upper part of the downpipe end cap inside the upper section of the support column, and weld the support end cap to the upper section of the support column; place vapor phase corrosion inhibitor on the lower part of the downpipe end cap inside the lower section of the support column, and weld the support end cap to the lower section of the support column. S4. Weld the upper section of the support column to the lower part of the compass deck extension, fix the lower section of the support column to the bridge extension of the bridge deck, fix the galvanized section of the bulwark elbow plate of the bridge extension of the bridge deck to the galvanized section of the top stiffener of the bulwark, and fix the galvanized section of the top stiffener of the bulwark to the lower end of the lower section of the support column.

[0015] The working principle and beneficial effects of the technical solution adopted in this invention are as follows: The ship's bridge structure described in this invention involves extending the downpipe from below the compass deck, passing it through the interior of a support pillar, and then exiting from below the pillar to near the downpipe opening on the upper surface of the bridge deck. This reduces obstructions to the observation line of sight of the bridge extension and ensures that the pillar's strength is not compromised when the downpipe passes through it, thus improving navigational safety. Specifically, the support pillar extending from the lower part of the compass deck is divided into an upper section, a lower section, and a middle section. The downpipe is first installed inside the middle section, with its upper end extending to the outside of the upper end of the middle section and its lower end extending to the outside of the lower end. Then, the upper section is installed around the downpipe at the upper end of the middle section, and the lower section is installed around the downpipe at the lower end of the middle section. When the upper section of the support is installed, the inner wall of the upper end of the middle section of the support is fixedly connected to the support joint connecting plate. The upper section of the support includes an upper section first component and an upper section second component with a semi-circular cross section. The upper section first component has a first notch on its side, and the upper section second component has a second notch on its side. The upper section first component and the upper section second component are fastened together and fixedly connected to the support joint connecting plate. The upper section of the support and the middle section of the support are fixedly connected by the support joint connecting plate. The downpipe branch pipe on the upper side of the downpipe extends through the first notch and the second notch to the outside of the upper section of the support. The upper end of the downpipe is fixedly connected to the downpipe end sealing plate, and the upper end of the upper section of the support is fixedly connected to the support end sealing plate. A support joint connecting pad is fixedly connected to the inner wall of the lower end of the middle section of the support column. The lower section of the support column includes a lower section first component and a lower section second component with a semi-circular cross-section. A first notch is provided on the side of the lower section first component, and a second notch is provided on the side of the lower section second component. The lower section first component and the lower section second component are fastened together and fixedly connected to the support joint connecting pad. The lower section of the support column and the middle section of the support column are fixedly connected by the support joint connecting pad. The downpipe branch pipe on the lower end of the downpipe extends to the outside of the lower section of the support column through the first notch and the second notch. The lower end of the downpipe is fixedly connected to the end sealing plate of the downpipe, and the lower end of the lower section of the support column is fixedly connected to the end sealing plate of the support column. The downpipe is inserted into the support pipe, extending out of the middle section of the support at both ends. The ends of the downpipe are equipped with welded sealing plates and connected to branch pipes that pass through the support pipe wall. Reinforcing sleeves are added at the openings where the branch pipes pass through the support (the openings are formed through the first and second notches) to ensure the support's strength. After forming a pipe-within-a-pipe structure with the support and downpipe, vapor-phase corrosion inhibitors are placed in the cavities at both ends of the support and sealed with welding plates to enhance the support's internal corrosion resistance. An additional 50mm allowance is added to the upper end of the support for adjustments to compensate for construction errors during the assembly of the compass deck sections. Similarly, an additional 50mm allowance is added to the lower end of the support for adjustments to compensate for construction errors. Where the lower section of the support is embedded in the bulwark, partial bulwark structures can be pre-installed and welded onto the support. After overall galvanizing, the sections are then welded on, further improving the support structure's corrosion resistance. This effectively conceals the downpipe inside the support, reducing the obstruction area, increasing the compass observation range, and improving work efficiency and quality.By optimizing the design of the nodes, it is ensured that there is no possibility of water leakage at the welded joints of the downpipes, which could lead to corrosion of the support columns, thus guaranteeing the structural support strength.

Detailed Implementation

[0017] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of the present invention, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part: As attached Figure 1 - Appendix Figure 5As shown, the present invention is a ship's bridge structure. A support column is provided between the bridge extension 12 of the bridge deck and the compass deck extension 13. The support column includes an upper section 1, a lower section 2, and a middle section 3. A downpipe 5 is installed inside the middle section 3.

The first component has a first notch on its side, and the second component has a second notch on its side. The first component and the second component are fastened together and fixedly connected to the support joint connecting pad 7. The drain pipe branch 6 on the lower side of the drain pipe 5 extends through the first and second notches to the outside of the lower section 2 of the support column. The lower end of the drain pipe 5 is fixedly connected to the drain pipe end sealing plate 8, and the lower end of the lower section 2 of the support column is fixedly connected to the support end sealing plate 9. The above structure proposes an improved technical solution to address the shortcomings of the prior art. The structure of this invention addresses the shortcomings of existing technologies by extending the downpipe 5 of the compass deck 21 from below the compass deck 21, passing through the interior of the support column, and then exiting from below the support column 20 to near the downpipe opening on the upper surface of the bridge deck. This reduces obstructions to the observation line of sight on the bridge extension of the bridge deck and ensures that the support column's strength is not compromised when the downpipe 5 passes through the support column 20, thus improving navigation safety. Specifically, the support column 20 extending from the lower part of the compass deck 21 is divided into an upper section 1, a lower section 2, and a middle section 3. The downpipe 5 is first installed inside the middle section 3, with its upper end extending to the outside of the upper end of the middle section 3 and its lower end extending to the outside of the lower end of the middle section 3. Then, the upper section 1 is installed around the downpipe at the upper end of the middle section 3, and the lower section 2 is installed around the downpipe 5 at the lower end of the middle section 3.When the upper section 1 of the support column is installed, the upper inner wall of the middle section 3 of the support column is fixedly connected to the support column joint connecting pad 7. The upper section 1 of the support column includes an upper section first component 14 and an upper section second component 15 with a semi-circular cross section. The upper section first component 14 has a first notch on its side, and the upper section second component 15 has a second notch on its side. The upper section first component 14 and the upper section second component 15 are fastened together and fixedly connected to the support column joint connecting pad 7. The upper section 1 of the support column and the middle section 3 of the support column are fixedly connected by the support column joint connecting pad 7. The downpipe branch pipe 6 on the upper side of the downpipe 5 extends through the first notch and the second notch to the outside of the upper section 1 of the support column. The upper end of the downpipe 5 is fixedly connected to the downpipe end sealing plate 8, and the upper end of the upper section 1 of the support column is fixedly connected to the support column end sealing plate 9. The lower inner wall of the middle section 3 of the support column is fixedly connected to the support column joint connecting pad 7. The lower section 2 of the support column includes a lower section first component and a lower section second component with a semi-circular cross section. The lower section first component has a first notch on its side, and the lower section second component has a second notch on its side. The lower section first component and the lower section second component are fastened together and fixedly connected to the support column joint connecting pad 7. The lower section 2 of the support column and the middle section 3 of the support column are fixedly connected through the support column joint connecting pad 7. The downpipe branch pipe 6 on the lower side of the downpipe 5 extends through the first notch and the second notch to the outside of the lower section 2 of the support column. The lower end of the downpipe 5 is fixedly connected to the downpipe end sealing plate 8. The lower end of the lower section 2 of the support column is fixedly connected to the support column end sealing plate 9. The downpipe 5 is inserted into the support pipe, extending out of the middle section 3 of the support at both ends. The end of the downpipe 5 is equipped with a welded sealing plate 8 and connected to a downpipe branch pipe 6, which passes through the pipe wall of the support 20. A reinforcing sleeve 4 is added at the opening where the downpipe branch pipe 6 passes through the support 20 (the opening is formed through the first and second notches) to ensure the strength of the support 20. After the support 20 and downpipe 5 form a pipe-in-pipe structure, vapor phase corrosion inhibitors are placed in the cavities at both ends of the support 20 and sealed with welding plates 9 to enhance the corrosion resistance of the support 20. An additional 50mm allowance is added to the upper end of the upper section 1 of the support for trimming during construction errors when assembling the compass deck sections. Similarly, an additional 50mm allowance is added to the lower end of the lower section 2 of the support for trimming during construction errors. The lower section 2 of the support is embedded in the bulwark, allowing for the pre-installation and welding of partial bulwark structures onto the support. After overall galvanizing, the upper sections are welded together to further improve the corrosion resistance of the support structure. In this way, the downpipe 5 is effectively concealed inside the support column 20, reducing the obstruction area for observation, increasing the observation range of the compass, and effectively improving the efficiency and quality of observation work. Through optimized node design, the possibility of water leakage at the downpipe weld seams leading to support column corrosion is prevented, ensuring the structural support strength. The ship's bridge structure described in this invention achieves downpipe concealment, thereby reducing obstruction of the observation area on the bridge deck, while simultaneously ensuring the structural strength of the support columns, reducing the corrosion rate of internal weld seams, ensuring the support column strength is not easily damaged, and improving the overall structural performance and service life.

Place vapor phase corrosion inhibitor on the upper part of the downpipe end sealing plate 8 inside the upper section 1 of the support column, and weld the support end sealing plate 9 at the end of the upper section 1 of the support column to the end of the upper section 1 of the support column; place vapor phase corrosion inhibitor on the lower part of the downpipe end sealing plate 8 inside the lower section 2 of the support column, and weld the support end sealing plate 9 at the end of the lower section 2 of the support column to the end of the lower section 2 of the support column; S2. Weld the upper section of the support column to the lower part of the compass deck extension 13, fix the lower section of the lower section 2 of the support column to the bridge 12 of the bridge deck extension, fix the galvanized section 10 of the bulwark elbow plate of the bridge 12 of the bridge deck to the galvanized section 11 of the top stiffener of the bulwark, and fix the galvanized section 11 of the top stiffener of the bulwark to the lower end of the lower section support column 3.

[0023] The beneficial effects of the structure of this invention are as follows: the downpipe 5 passes through the interior of the support column 20, achieving partial concealment of the downpipe 5 and reducing the observation obstruction area on the bridge deck. This allows the welded joints of the downpipe branch pipe 6 to be enclosed in localized areas at both ends of the support column 20, and by filling the enclosed, narrow space at the ends of the support column 20 with a vapor-phase corrosion inhibitor, the corrosion rate of the weld seams inside the support column 20 is inhibited, ensuring that the strength of the support column 20 is not easily compromised. The lower end of the support column 20 is pre-welded to the bulwark component and then integrally galvanized. This not only increases the overall galvanized layer of the support column but also prevents damage to the galvanized layer during welding to the bulwark, thus increasing the coating protection of the support column.
