[0002] The hull deck and wall plate structure is usually formed by sequentially butting and welding a plurality of segmented steel plates. The hull is a long strip-shaped steel enclosure structure. Due to the influence of waves, the hull will be subjected to a large and frequent impact. At this time, the connecting joints between the segmented steel plates will be subjected to repeated tensile and compressive forces. Therefore, the connecting joints between the segmented steel plates need to have good tensile and compressive resistance. However, the two adjacent segmented steel plates are fixedly connected in a rigid structure by welding. Since the hull segmented steel plates and the connecting joints between the hull segmented steel plates are both rigid structures, when the hull is subjected to a large impact force, the connecting joints between the hull segmented steel plates need to instantaneously withstand a large tensile force and pressure impact. In order to ensure the strength of the hull structure, the steel plates need to be thickened to resist deformation under pressure or tension, which greatly increases the weight of the hull and improves the energy consumption of the ship during operation.

DETAILED DESCRIPTION

[0031] The specific embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0032] In the description of the present application, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. It should be understood that the terms "first", "second" and the like are used to describe various information in the present application, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, the "first" information can also be referred to as "second" information, and similarly, the "second" information can also be referred to as "first" information without departing from the scope of the present application.

[0033] The segmented steel plate connecting device of the present application is used to connect the first segmented steel plate 100 and the second segmented steel plate 200 arranged in opposite intervals, as shown in Figure 1 , Figure 2 The segmented steel plate connecting device of the present application comprises:

[0034] The connecting plate 1 is provided with a collapse groove 11 formed by bending, and the two side groove walls of the collapse groove 11 are connected with the first segmented steel plate 100 and the second segmented steel plate 200, respectively;

[0035] The elastic top support 2 is arranged in the collapse groove 11, and the two ends of the elastic top support 2 abut against the two side groove walls of the collapse groove 11, respectively;

[0036] The elastic stretching piece 3 is arranged at the slot opening of the collapse groove 11, and two ends of the elastic stretching piece 3 are connected to the two side groove walls of the collapse groove 11 respectively.

[0037] Specifically, when the first hull steel plate and the second hull steel plate need to bear the pressure impact generated by waves, the collapse groove 11 can collapse inward, and the elastic bracing piece 2 can buffer the pressure impact when the collapse groove 11 collapses, so as to reduce the instantaneous pressure impact value borne by the first hull steel plate and the second hull steel plate. Moreover, after the pressure impact is dissipated, the elastic bracing piece 2 can brace the two side groove walls of the collapse groove 11 to open outward and reset, so as to prepare for the pressure impact again. When the first hull steel plate and the second hull steel plate need to bear the tensile impact generated by waves, the slot opening of the collapse groove 11 will expand outward, and the elastic stretching piece 3 can buffer the tensile impact when the slot opening of the collapse groove 11 expands outward, so as to reduce the instantaneous tensile impact value borne by the first hull steel plate and the second hull steel plate. Moreover, after the tensile impact is dissipated, the elastic stretching piece 3 can pull the two side groove walls of the collapse groove 11 to close inward and reset, so as to prepare for the tensile impact again. Therefore, the segmented steel plate connecting device can improve the wave impact resistance of the hull, reduce the instantaneous tensile impact value and the instantaneous pressure impact value borne by the first hull steel plate and the second hull steel plate, so that the thickness of the first hull steel plate and the second hull steel plate can be reduced, and the weight of the hull can be reduced. The segmented steel plate connecting device can be arranged at a position of the hull that needs to bear a large impact force. By embedding and installing the segmented steel plate connecting device in the deck and the wall plate of the high deformation area, the maximum deformation value of the structure of the area can be increased, so that the safety of the deck and the wall plate structure can be protected.

[0038] In order to adjust the bracing force of the elastic bracing piece 2 on the two side groove walls of the collapse groove 11, in the embodiment, the elastic bracing piece 2 includes a length-adjustable bracing piece 21, a first rubber block 22 arranged at one end of the bracing piece 21, and a second rubber block 23 arranged at the other end of the bracing piece 21. The first rubber block 22 and the second rubber block 23 are respectively in abutment with the two side groove walls of the collapse groove 11. Specifically, by lengthening the bracing piece 21, the bracing force of the elastic bracing piece 2 on the two side groove walls of the collapse groove 11 can be increased, and by shortening the bracing piece 21, the bracing force of the elastic bracing piece 2 on the two side groove walls of the collapse groove 11 can be reduced. By adjusting the length of the bracing piece 21, the deformation amount of the segmented steel plate connecting device when the segmented steel plate connecting device is elastically deformed by impact can be controlled. In other embodiments of the present application, for a specific ship type, the elastic bracing piece 2 can be arranged as an integral columnar rubber block.

[0039] Further, the top support 21 comprises a first top support block 211, a second top support block 212 and a top support rod 213, the first top support block 211 and the second top support block 212 are arranged in opposite interval, one end of the top support rod 213 is screwed with the first top support block 211, the other end of the top support rod 213 is screwed with the second top support block 212, the screw threads of the two ends of the top support rod 213 are opposite; the end of the first top support block 211 away from the top support rod 213 is connected with the first rubber block 22, the end of the second top support block 212 away from the top support rod 213 is connected with the second rubber block 23. Specifically, when the top support 21 needs to be lengthened, the top support rod 213 is rotated to make the first top support block 211 and the second top support block 212 move away from each other, when the top support 21 needs to be shortened, the top support rod 213 is rotated to make the first top support block 211 and the second top support block 212 move close to each other.

[0040] In order to adjust the tension of the elastic tensioning member 3 on the two side walls of the collapse groove 11, in the embodiment, the elastic tensioning member 3 comprises a telescopic rod 32 and a tension spring 31 connected to one end of the telescopic rod 32, and the end of the telescopic rod 32 away from the tension spring 31 and the end of the tension spring 31 away from the telescopic rod 32 are connected to the two side walls of the collapse groove 11 respectively. Specifically, when the tension of the elastic tensioning member 3 on the two side walls of the collapse groove 11 needs to be increased, the telescopic rod 32 is lengthened; in the embodiment, the telescopic rod 32 comprises a sleeve and screw rods screwed at both ends of the sleeve, and hexagonal wrenching parts are arranged on the outer side of the sleeve and the ends of the screw rods away from the sleeve for easy screwing.

[0041] In the embodiment, the two side walls of the collapse groove 11 are provided with a first connecting section 12 extending to the first segmented steel plate 100 and a second connecting section 13 extending to the second segmented steel plate 200 at the positions close to the slot, the first connecting section 12 is connected to the second segmented steel plate 200, and the second connecting section 13 is connected to the second segmented steel plate 200; the segmented steel plate connecting device comprises a fastener 5 and a cover plate 4 covering the collapse groove 11, one end of the cover plate 4 is connected to the first connecting section 12, the other end of the cover plate 4 is provided with a mounting groove 41, the groove width of the mounting groove 41 matches the diameter of the fastener 5, the groove length of the mounting groove 41 extends along the width direction of the collapse groove 11, and the fastener 5 passes through the mounting groove 41 and is screwed with the second connecting section 13. Specifically, when the collapse groove 11 is subjected to pressure impact, the cover plate 4 can be deformed to further improve the buffering capacity of the collapse groove 11 to pressure impact, and the cover plate 4 covering the collapse groove 11 can also play a blocking role to avoid objects on the ship falling into the collapse groove 11. Specifically, when the collapse groove 11 is subjected to pressure or tension, the middle part of the cover plate 4 elastically deforms, and at the same time, the end of the cover plate 4 connected to the second connecting section 13 can slide relative to the second connecting section 13 due to the mounting groove 41, and the elastic deformation of the cover plate 4 further improves the buffering capacity of the segmented steel plate connecting device of the embodiment to pressure and tension impact.

[0042] In this embodiment, as shown in the figure, the collapse groove 11 is a U-shaped groove. Specifically, the connecting plate 1 includes a first connecting section 12, a folding-off section 14 bent to one side of the first connecting section 12, an arc-shaped transition section 15, a folding-back section 16, and a second connecting section 13 in sequence along the direction from the first segmented steel plate 100 to the second segmented steel plate 200, and the folding-off section 14, the arc-shaped transition section 15, and the folding-back section 16 enclose the collapse groove 11. Figure 1

[0043] In this embodiment, the rubber pad 6 is bonded to the first connecting section 12 and the second connecting section 13 by glue.

[0044] In other embodiments of the present application, a backing plate 7 can be welded on the first connecting section 12 and the second connecting section 13, and the two ends of the elastic stretching member 3 are connected to the corresponding backing plates 7, and the rubber pad 6 is also connected to the corresponding backing plates 7.

[0045] In this embodiment, after the connecting plate 4 is connected to the first connecting section 12 and the second connecting section 13, the folding-off section 14, the arc-shaped transition section 15, the folding-back section 16, and the connecting plate 4 enclose a cylindrical structure, and the better the elasticity of the cylindrical structure, the more conducive to the impact resistance of the segmented steel plate connecting device. In this embodiment, in order to improve the elasticity of the cylindrical structure, the material of the connecting plate 1 and the connecting plate 4 is spring steel.

[0046] In this embodiment, the connecting plate 1 is arranged along the length direction of the butt joint gap of the first segmented steel plate 100 and the second segmented steel plate 200, the collapse groove 11 extends along the length direction of the butt joint gap of the first segmented steel plate 100 and the second segmented steel plate 200, multiple elastic supporting members 2 are arranged in the collapse groove 11, and multiple elastic stretching members 3 are arranged at the slots of the collapse groove 11.

[0047] The above-mentioned embodiment of the installation method of the segmented steel plate connecting device includes the following steps:

[0048] Step S1, installing the elastic supporting member 2 in the collapse groove 11;

[0049] Step S2, installing the elastic stretching member 3 at the slot of the collapse groove 11;

[0050] Step S3, fixing the two ends of the connecting plate 1 to the first segmented steel plate 100 and the second segmented steel plate 200, respectively.

[0051] Before step S1, it includes:

[0052] ​Step S01, the length of the top support 21 is shortened, so that the length of the elastic top support 2 is less than the slot width of the collapse groove 11;

[0053] After step S1 and before step S2, it includes:

[0054] Step S11, the length of the telescopic rod 32 is lengthened, so that the length of the elastic tensioning member 3 is greater than the slot width of the collapse groove 11;

[0055] After step S2 and before step S3, it includes:

[0056] Step S21, the length of the top support 21 is lengthened, and the length of the telescopic rod 32 is shortened, so that the two side walls of the collapse groove 11 are subjected to both the pressing force of the top support 21 and the pre-tensioning force of the elastic tensioning member 3.

[0057] The arrangement of the telescopic rod 32 and the top support 21 not only realizes the adjustment of the size of the pre-pressing force and the pre-tensioning force of the collapse groove 11, but also greatly facilitates the installation of the segmented steel plate connecting device.

[0058] In summary, the segmented steel plate connecting device includes a connecting plate 1, an elastic top support 2 and an elastic tensioning member 3. The connecting plate 1 is provided with a collapse groove 11 formed by bending, and the two side walls of the collapse groove 11 are connected with a first segmented steel plate 100 and a second segmented steel plate 200 respectively. The elastic top support 2 is arranged in the collapse groove 11, and the two ends of the elastic top support 2 are in abutment with the two side walls of the collapse groove 11 respectively. When the first ship body steel plate and the second ship body steel plate need to withstand the pressure impact generated by the waves, the collapse groove 11 can collapse inward, and at the same time, the elastic top support 2 can be pressed to play a buffering role for the pressure impact, thereby reducing the instantaneous pressure impact value of the first ship body steel plate and the second ship body steel plate. The elastic tensioning member 3 is arranged at the slot opening of the collapse groove 11, and the two ends of the elastic tensioning member 3 are connected with the two side walls of the collapse groove 11 respectively. When the first ship body steel plate and the second ship body steel plate need to withstand the tension impact generated by the waves, the slot opening of the collapse groove 11 will expand outward, and at the same time, the elastic tensioning member 3 will be pulled to play a buffering role for the tension impact, thereby reducing the instantaneous tension impact value of the first ship body steel plate and the second ship body steel plate. Therefore, the segmented steel plate connecting device can improve the wave impact resistance of the ship body, reduce the instantaneous tension impact value and the instantaneous pressure impact value of the first ship body steel plate and the second ship body steel plate, so as to reduce the thickness of the first ship body steel plate and the second ship body steel plate, and further reduce the weight of the ship body.

[0059] The above merely describes the preferred embodiments of the present application, and it should be pointed out that, for those skilled in the art, several improvements and replacements can be made without departing from the technical principles of the present application, and these improvements and replacements should also be considered as the protection scope of the present application.
