Description

Technical Field

[0001] This invention relates to the field of ship structural design and construction technology, and in particular to a combined support column that meets the requirements for use in roll-on / roll-off equipment. Background Technology

[0002] In the design of car carriers, struts, as crucial stress-support components, are typically installed between the various movable decks, which in turn require the installation of various roll-on / roll-off (Ro-Ro) equipment to meet performance requirements. Current ship designs often separate the Ro-Ro equipment from the struts, using side T-beams as Ro-Ro supports. However, using side T-beams as Ro-Ro supports for installing equipment often presents challenges such as large curved surfaces, high precision requirements, difficult on-site construction, and high construction costs. Furthermore, adding additional Ro-Ro reinforcement increases steel costs and the risk of weld overlap. Summary of the Invention

[0003] In view of the above-mentioned problems existing in the prior art, the present invention provides a combined support column that meets the requirements of roll-on / roll-off equipment, so as to solve the technical problems of large curved surface lines, high precision requirements, difficult on-site construction, and high construction costs existing in the prior art.

[0004] This invention provides a combined support column that meets the requirements for use with roll-on / roll-off equipment, comprising: transverse ribs, longitudinal wall plates, roll-on / roll-off equipment, and roll-on / roll-off guide rails. The transverse ribs are arranged in pairs, with the two pairs of transverse ribs corresponding to each other on both sides of the combined support column. The longitudinal wall plates are also arranged in pairs, with the two pairs of longitudinal wall plates corresponding to each other on the other two sides of the combined support column. The transverse ribs and longitudinal wall plates are vertically fixed in sequence to form the combined support column, and the edges of the transverse ribs extend beyond the edges of the longitudinal wall plates to form cantilevered sections. The roll-on / roll-off equipment and the roll-on / roll-off guide rails are both fixedly mounted on the transverse ribs, and the roll-on / roll-off guide rails are located at the cantilevered sections of the transverse ribs.

[0005] In one embodiment, it also includes, Several partitions are arranged at intervals along the length of the combined support column within the column cavity formed by the transverse ribs and the longitudinal wall plates, and the partitions are fixed perpendicularly to the partitions of the transverse ribs and the longitudinal wall plates.

[0006] In one embodiment, it also includes, Several elbow plates are arranged at intervals along the length of the combined support column at the inside corner formed by the cantilevered section of the transverse rib plate and the longitudinal wall plate, and their plates are fixed perpendicularly to the plates of the transverse rib plate and the longitudinal wall plate.

[0007] In one embodiment, an elbow plate is provided at the corresponding height of the partition.

[0008] In one embodiment, the width of the cantilevered slab segment is not less than 15 mm.

[0009] In one embodiment, the lower section of the cantilever plate segment is a basic part with a width of 15mm, and the upper section is a widened part with a width greater than 15mm. The widened part is, from top to bottom, a toe section, a main body section, and a transition section, and the width of the toe section, the main body section, and the transition section gradually decreases.

[0010] In one embodiment, the width of the widened main body section is A = (LB) / 2 + 15 mm, where L is the maximum distance between the two roll-on guides and B is the maximum distance between the two longitudinal wall plates.

[0011] In one embodiment, the width of the widened transition section is C = 4(A-15) mm, where A is the width of the widened main body section.

[0012] In one embodiment, an oblong weight-reduction hole is provided in the middle of one of the longitudinal wall panels.

[0013] Compared with the prior art, the beneficial effects of the combined support column provided by the embodiments of the present invention that meets the requirements of roll-on / roll-off equipment are as follows: The embodiments of the present invention effectively combine the support column and the roll-on / roll-off support by adding cantilever plate segments as roll-on / roll-off support components at the edge of the transverse rib plate. Under the premise of meeting the stress of the support column, it also serves as a roll-on / roll-off support component for the movable deck, effectively saving steel costs, reducing the difficulty of on-site welding construction, and ensuring forming accuracy.

Well-known and / or repeated functions and structures are not described in detail to ascertain the true intent based on the user's historical operations, and to avoid unnecessary or redundant details that would obscure this application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in various ways with substantially any suitable detailed structure.

[0022] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0023] The principles and features of the present invention are described below with reference to the accompanying drawings. The embodiments described are for illustrative purposes only and are not intended to limit the scope of the invention. The following description, in conjunction with... Figure 1-5 The preferred embodiments of the present invention will be described in further detail below: like Figure 1-5As shown, this embodiment of the invention provides a combined support column that meets the requirements of roll-on / roll-off equipment, including: a horizontal rib plate 1, a longitudinal wall plate 2, a roll-on / roll-off equipment 7, and a roll-on / roll-off guide rail 5. The horizontal rib plates 1 are arranged in pairs, with the two pairs of horizontal rib plates 1 corresponding to each other on both sides of the combined support column. The longitudinal wall plates 2 are also arranged in pairs, with the two pairs of longitudinal wall plates 2 corresponding to each other on the other two sides of the combined support column. The horizontal rib plates 1 and the longitudinal wall plates 2 are vertically fixed in sequence to form the combined support column, and the edge of the horizontal rib plate 1 extends beyond the edge of the longitudinal wall plate 2 to form a cantilevered plate segment. The roll-on / roll-off equipment 7 and the roll-on / roll-off guide rail 5 are both fixedly arranged on the horizontal rib plate 1, and the roll-on / roll-off guide rail 5 is arranged at the cantilevered plate segment of the horizontal rib plate 1. By setting the cantilevered plate segment integrally connected with the horizontal rib plate 1 as a roll-on / roll-off support component, the on-site construction difficulty is effectively reduced and the construction cost is saved.

[0024] In one embodiment, the composite support also includes, like Figure 5 As shown, several partitions 3 are arranged at intervals along the length of the combined support column within the column cavity formed by the transverse rib plate 1 and the longitudinal wall plate 2, and their plates are fixed perpendicularly to the plates of the transverse rib plate 1 and the longitudinal wall plate 2. The partitions 3 can serve as reinforcement for the support column itself, and can also serve as reinforcement for the roll-on support, thereby reducing steel and welding costs.

[0025] In one embodiment, the composite support also includes, Several elbow plates 4 are arranged at intervals along the length of the combined support column at the inside corner formed by the cantilevered section of the transverse rib plate 1 and the longitudinal wall plate 2, and their plates are fixed perpendicularly to the plates of the transverse rib plate 1 and the longitudinal wall plate 2.

[0026] like Figure 5 As shown, in one embodiment, an elbow plate 4 is provided at the height of the partition 3. The four small elbow plates 4 around the partition 3 can weaken the stress concentration caused by the rolling guide rail 5 being welded to the transverse rib plate 1, and extend the service life of the support column.

[0027] In one embodiment, the width of the cantilevered slab segment is not less than 15 mm.

[0028] like Figure 2 As shown, in one embodiment, the lower section of the cantilever plate segment is a basic part with a width of 15mm, and the upper section is a widened part with a width greater than 15mm. The widened part is, from top to bottom, a toe section, a main body section, and a transition section, and the width of the toe section, the main body section, and the transition section gradually decreases.

[0029] The root of the uppermost part of the transverse rib plate 1 is designed as a softened toe end, which can greatly reduce the stress on the upper deck and slowly and evenly distribute the stress points, thus extending the service life of the deck. In one embodiment, the toe end section is connected to the main body section with an arc-shaped chamfer. Under normal circumstances, the chamfer radius is 150mm, which is sufficient to reduce stress and does not need to be too large.

[0030] like Figure 2 As shown, in one embodiment, the width of the widened main body section is A=(LB) / 2+15mm, where L is the maximum distance between the two roll-on guide rails 5 and B is the maximum distance between the two longitudinal wall plates 2. That is, under the premise of meeting the needs of the roll-on equipment 7, the widening distance of the main body section above the transverse rib plate 1 is set to A=(LB) / 2+15mm, and an optimal distance of 15mm is also reserved for the lower basic part. Both places will eventually extend out a 15mm clearance corner joint gap to ensure the consistency of the corner joint weld.

[0031] like Figure 2 As shown, in one embodiment, the width of the widened transition section is C=4(A-15)mm, where A is the width of the main body section of the widened section. That is, the upper and lower transition distance adopts a better reasonable ratio of 4:1, i.e., C=4(A-15)mm. This design can effectively reduce the stress caused by the stress change at the corner, and slowly and evenly transfer the force to the support body, reducing the stress concentration on the support during the operation of the roll-on / roll-off equipment.

[0032] like Figure 3 As shown, in one embodiment, an oblong weight-reducing hole 6 is provided in the middle of one of the longitudinal wall panels 2. That is, one of the longitudinal wall panels 2 is designed as an open wall panel with an oblong hole, with 500mm left at the top and bottom and a distance f of 75~125mm left on both sides. Under the premise of meeting the strength requirements of the panel, the weight of the support can be reduced as much as possible. At the same time, the weight-reducing hole 6 can also serve as a welding manhole for the partition 3, etc., which also facilitates the welding construction of the support.

[0033] Furthermore, in one embodiment, the elongated hole 6, which serves as the weight reduction hole of the longitudinal wall plate 2, is designed as follows: hole height = plate frame length M - 500 - 500mm, hole width = plate frame width - 2 * f, where f = 75 ~ 125mm, and end hole guide circle R600mm.

[0034] In one embodiment, the longitudinal wall plate 2 is corner-welded to the transverse rib plate 1, and the partition plate 3 is welded inside the combined column and corner-welded to the transverse rib plate 1 and the longitudinal wall plate 2; the elbow plate 4 is corner-welded to the transverse rib plate 1 and the longitudinal wall plate 2. Where there is no roll-on / roll-off equipment at the lower end of the transverse rib plate 1, a 15mm weld leg gap is left. At the upper end where there is roll-on / roll-off equipment for welding, the designed spacing is A=(LB) / 2+15mm, and the distance for the transition beveling at both ends is designed as C=4(A-15)mm.

[0035] The composite support structure can meet the stress requirements of the support structure and also serve as a roll-on / roll-off support for the movable deck, saving steel and construction costs, reducing on-site construction difficulty, and accelerating the construction cycle.

[0036] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
