Description
Technical Field
[0001] The utility model relates to the technical field of ships, in particular to a beam-column combined support structure in the engine room area of a container ship. Background Art
[0002] The top of the main deck in the engine room area of a container ship is commonly used for loading containers. Its load is borne by the cross-beam system structure composed of main deck strong beams and longitudinal girders, and is transmitted downward by support structures such as pillars and bulkheads. The main deck strong beams and longitudinal girders generally use T-shaped profiles. Due to the layout requirements of the main engine, large rounded rectangular holes need to be opened in the middle of each layer of decks below the main deck. The pillars supporting the main deck can only be arranged on both sides of the openings, resulting in a relatively large support span for the strong beams on the main deck. The strong beams are subjected to large bending and shear loads, and their strength often fails to meet the requirements. Usually, methods such as increasing the height of the strong beam web and increasing the thickness of the web and the panel are adopted to improve the bending and shear resistance of the strong beam. However, due to the requirements for lifting equipment in the engine room in the lower space, the height of the strong beam web is often restricted and cannot be too large. Therefore, usually, the thickness of the web and the panel of the strong beam needs to be increased to a very large value to meet the requirements.
[0003] The prior art generally uses a single T-shaped profile as the strong beam to support the corner load of the support box. In the case of limited storey height, the thickness of the web and the panel of the T-shaped profile needs to be taken as a very large value (generally more than 30 mm) to meet the strength requirements. The welding requirements for thick plates are high, which increases the construction difficulty of the shipyard. And for plates thicker than 30 mm, the steel grade requirements will be increased by one grade, increasing the material cost. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the above-mentioned defects existing in the prior art and provide a beam-column combined support structure in the engine room area of a container ship.
[0005] The utility model solves the above technical problem through the following technical solutions:
[0006] A beam-column combined support structure in the engine room area of a container ship, which includes a strong beam fixedly arranged at the bottom of the deck. The strong beam includes two beams, and each beam is a T-shaped profile composed of a beam panel and a beam web; the distance between the two beams is not greater than one rib pitch; two pillars are arranged below the strong beam; each pillar is a C-shaped pillar composed of two pillar panels and a pillar web; the two pillar panels of the pillar are respectively aligned with the two beam webs.
[0007] Furthermore, a longitudinal girder is also arranged at the bottom of the deck; the pillar web is aligned with the web of the longitudinal girder.
[0008] Furthermore, the beam is fixedly arranged between two longitudinal strong structures, and the two ends of the beam are respectively fixedly connected to the two longitudinal strong structures.
[0009] Further, both of the two struts are disposed between two longitudinal strong structures.
[0010] Further, the top of the strut panel is fixedly connected to the crossbeam panel.
[0011] Further, the upper end of the strut panel has an enlarged portion with a gradually increasing width from bottom to top; the enlarged portion of the strut panel is fixedly connected to the crossbeam panel.
[0012] Further, gussets are fixedly provided on both sides of the upper end of the strut, and the gussets are simultaneously fixedly connected to the crossbeam panel.
[0013] Further, the gussets are aligned with the strut web.
[0014] Further, the height of the crossbeam web is the same as the height of the longitudinal girder web.
[0015] Further, the connection portion between the crossbeam panel and the longitudinal girder panel is a guide arc structure.
[0016] The beneficial effects of the present utility model are as follows: The present utility model uses a double T-shaped profile combined beam as the main deck strong crossbeam to support the corner load. When the web height is limited, the thickness of the T-shaped profile web and panel can be effectively reduced to within 30 mm, saving the cost of the shipyard and reducing the construction difficulty. Through the solution of the present utility model, the problem of the layout height space in the engine room can be better solved, which is more conducive to the layout of other equipment. The present utility model uses a double T-shaped profile strong crossbeam to replace the single T-shaped profile strong crossbeam in the prior art, and solves the problem of the effective support of the deck plate frame structure for the top container load when the engine room deck layer height is limited; the structure form is simple, the use of thick plates is avoided, the construction is convenient and the cost is saved.

[0022] The following is a preferred embodiment, and the present utility model will be described more clearly and completely in conjunction with the accompanying drawings.
[0023] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a beam-column combined support structure in the engine room area of a container ship includes strong beams fixedly arranged at the bottom of the deck 40. The strong beams include two beams 10, and the beam 10 is a T-shaped section composed of a beam panel 11 and a beam web 12; the distance between the two beams 10 is not greater than one rib pitch.
[0024] There are two columns 20 arranged below the strong beams; the column 20 is a C-shaped column composed of two column panels 21 and one column web 22.
[0025] The two column panels 21 of the column 20 are respectively aligned with the two beam webs 12. The width of the column web 22 is equal to the distance between the two beams.
[0026] The top of the column panel 21 is fixedly connected to the beam panel 11.
[0027] The upper end of the column panel 21 has an enlarged portion 23 with a gradually increasing width from bottom to top; the enlarged portion 23 of the column panel is fixedly connected to the beam panel 11.
[0028] Elbows 24 are fixedly arranged on both sides of the upper end of the column 20, and the elbows 24 are simultaneously fixedly connected to the beam panel 11. The elbows 24 are aligned with the column web 22.
[0029] There is also a longitudinal girder 30 arranged at the bottom of the deck 40; the column web 22 is aligned with the web 32 of the longitudinal girder.
[0030] The height of the beam web 12 is the same as the height of the web 32 of the longitudinal girder. The connection between the beam panel 11 and the panel 31 of the longitudinal girder is a guide arc structure 33.
[0031] The beam 10 is fixedly arranged between two longitudinal strong structures 41, and the two ends of the beam 10 are respectively fixedly connected to the two longitudinal strong structures 41. The two columns 20 are both arranged between the two longitudinal strong structures 41.
[0032] There is a bottom elbow 25 arranged below the column 20, and the bottom elbow 25 is fixedly connected to the platform 26 for supporting the column.
[0033] The deck is used to support containers, and the concentrated load at the corner of the container is located between the two beams. Two T-shaped section beams form a strong beam; two C-shaped columns are arranged below the strong beam, and the two C-shaped columns support the two T-shaped section beams of the strong beam. Elbows are arranged at the top of the C-shaped column to strengthen the structure. The intersection of the T-shaped section panel and the longitudinal girder panel is connected as a whole through a guide arc structure.
[0034] Compared with the existing technology, the thicknesses of the web and the panel of the T-shaped section used as the cross beam in the utility model can be effectively reduced.
[0035] Taking a 1300 TEU container ship as an example, for the strong cross beam at the superposition of 4 20-foot container corners on the deck in the engine room area, on the premise that the height of the web is limited to 600 mm, if the traditional single T-shaped section technology is adopted, the panel and the web need steel plates with a thickness of 40 mm and D-grade steel is required. While adopting the solution of the utility model, the thickness of the web of the strong cross beam only needs to be 20 mm, and the thickness of the panel only needs to be 25 mm. And according to the classification society specifications, only A-grade steel is needed. This not only saves costs but also reduces the construction difficulty of cutting and welding.
[0036] The utility model adopts a combined double T-shaped section beam as the strong cross beam on the main deck to support the corner load of the container. When the height of the web is limited, the thicknesses of the web and the panel of the T-shaped section can be effectively reduced to within 30 mm, saving the cost of the shipyard and reducing the construction difficulty. Through the solution of the utility model, the problem of the engine room layout height space can be better solved, which is more conducive to the layout of other equipment.
[0037] The utility model provides a beam-column combined structure located in the engine room area of a container ship for supporting the container cargo load on the main deck. The combined double T-shaped section strong cross beam is adopted to replace the single T-shaped section strong cross beam in the original technology, solving the problem of the effective support of the deck grillage structure for the container load on the top when the height of the engine room deck layer is limited; the structural form is simple, the use of thick plates is avoided, the construction is convenient and the cost is saved.
[0038] Although the specific implementation manners of the utility model are described above, those skilled in the art should understand that this is only for illustration. The protection scope of the utility model is defined by the appended claims. Without departing from the principle and essence of the utility model, those skilled in the art can make various changes or modifications to these implementation manners, but these changes and modifications all fall within the protection scope of the utility model.
