[0043] The present application will be more clearly and completely explained by way of examples and in conjunction with the accompanying drawings, but the present application is not limited in the scope of the described examples.

[0044] As Figure 1 and Figure 2As shown, the present application discloses a connecting assembly, the connecting assembly comprises a corrugated plate 1 and a folded plate 2, the folded plate 2 is provided with a bending part 21, the bending part 21 protrudes towards the direction close to the corrugated plate 1, at least part of the area of the corrugated plate 1 coincides with the projection of the bending part 21 in the horizontal direction, the coincident area of the corrugated plate 1 has a first face 4 facing the bending part 21 in the horizontal direction, the shape of the first face 4 is matched with the shape of the bending part 21, and the first face 4 is connected with the bending part 21. The corrugated plate 1 and the folded plate 2 cooperate with each other, at least part of the area on the corrugated plate 1 coincides with the projection of the bending part 21 in the horizontal direction, that is, the lower end of the corrugated plate 1 extends downwards and gradually approaches the bending part 21, the first face 4 of the part of the corrugated plate 1 extending downwards facing the bending part 21 in the horizontal direction is matched with the shape of the bending part 21 by grinding treatment, and finally the first face 4 is tightly connected with the bending part 21 and connected with each other, solving the defect that the connecting mode of the corrugated plate 1 and the folded plate 2 in the prior art is unstable, resulting in a large amount of welding on site and large accumulated welding stress, and making the corrugated plate 1 prone to secondary deformation.

[0045] In the embodiment of the present application, in order to match the shape of the first face 4 with the shape of the bending part 21, the first face 4 can be ground into a concave face away from the bending part 21, thereby increasing the contact area of the corrugated plate 1 and the folded plate 2, and increasing the connecting strength of the corrugated plate 1 and the folded plate 2.

[0046] Specifically, Figure 2 The left side is a connecting schematic diagram before optimization of the prior art, and the right side is a connecting schematic diagram after optimization of the present application, and the two are compared. From the left side of the figure in the Figure 2 As can be seen from the left side of the figure in the Figure 2 As can be seen from the right side of the figure in the

[0047] As shown in the left side of the figure in the Figure 2As shown, the length of the overlapping area of the corrugated plate 1 in the vertical direction is at least 10 mm. The length of the overlapping area of the corrugated plate 1 in the vertical direction is at least 10 mm, which ensures that the extension length of the corrugated plate 1 can fully meet the contact with the bending part 21, ensures that the two fully abut, reduces the gap, thereby reducing the welding amount and improving the stability of the connecting assembly.

[0048] Specifically, the reason for the deformation of the corrugated plate 1 is that the welding amount of the corrugated plate 1 and the folded edge plate 2 is large, which causes welding stress concentration; the corrugated plate 1 is thin and soft in structure, and is not resistant to stretching and compression, and segmented transportation and hoisting and turning will cause the corrugated plate 1 to deform, and forced assembly or secondary heat input under the condition of corrugated plate 1 deformation will sharply deform the corrugated plate 1, increasing the difficulty of flattening the corrugated plate 1. In the embodiment of the present application, the corrugated plate 1 is made of 4-5 mm thick bending steel plate, which is used for room partition, and by arranging the length of at least 10 mm in the vertical direction of the overlapping area, the defect that the original corrugated plate 1 and the folded edge plate 2 need 3-4 welding passes due to the gap between them, causing large cumulative welding stress and secondary deformation, is compensated. The problem of heat input caused by too much welding is solved, and the problem of easy deformation of the corrugated plate 1 caused thereby is reduced as much as possible.

[0049] As shown in Figure 3 , the corrugated plate 1 includes a first plate 11 and a second plate 12, and the first plate 11 and the second plate 12 are alternately connected in the extension direction of the folded edge plate 2 to form a corrugated shape.

[0050] In specific use, the first plate 11 and the second plate 12 are integrally formed, and in other embodiments, the first plate 11 and the second plate 12 can also be separately arranged and connected by a connecting piece.

[0051] Specifically, as shown in Figure 3 , the length of the corrugated plate 1 in the extension direction of the folded edge plate 2 is also extended by at least 10 mm, which facilitates the processing of the corrugated plate 1 later, and the length is adapted to the folded edge plate 2 to achieve good connection effect. The second plate 12 has a recessed end.

[0052] The projection of the corrugated plate 1 in the height direction is completely overlapped with the projection of the folded edge plate 2 in the height direction. The projection of the corrugated plate 1 in the height direction is completely overlapped with the projection of the folded edge plate 2 in the height direction, that is, the extension lengths of the two are the same, and on this basis, welding can reduce the workload on site and improve work efficiency; at the same time, the complete overlap of the projections of the two in the height direction significantly increases the contact area between the two, making the connection more stable.

[0053] As shown in Figure 2As shown, the first surface 4 and the bending part 21 are connected by welding. The first surface 4 and the bending part 21 are connected by welding, which can ensure stable connection and prevent loosening.

[0054] The application further discloses a connecting device comprising the connecting assembly. The connecting device provided with the connecting assembly has high commercial value and practical significance. The corrugated plate 1 and the edge folding plate 2 cooperate with each other. At least part of the area on the corrugated plate 1 overlaps the horizontal projection of the bending part 21, that is, the lower end of the corrugated plate 1 extends downward and gradually approaches the bending part 21. The first surface 4 of the corrugated plate 1 facing the bending part 21 in the horizontal direction is polished to adapt to the shape of the bending part 21. Finally, the first surface 4 and the bending part 21 are tightly fitted and connected to each other, solving the problem of unstable connection between the corrugated plate 1 and the edge folding plate 2 in the prior art, which leads to a large amount of welding on site and large accumulated welding stress, and making the corrugated plate 1 prone to secondary deformation.

[0055] As shown in the figure, Figure 1 The connecting device further comprises a reinforcing member 3. One end of the reinforcing member 3 is connected with the connecting assembly, and the other end of the reinforcing member 3 is connected with the mounting surface. The reinforcing member 3 is connected with the connecting assembly at one end and connected with the mounting surface at the other end, thereby providing strong support for the connecting assembly, facilitating correct initial installation of the connecting assembly, maintaining high accuracy, avoiding unnecessary inclination, preventing loosening of the connecting assembly during on-site welding, and improving work efficiency.

[0056] In specific use, the reinforcing member is welded with the connecting assembly and the mounting surface respectively to increase the connection strength and stability of the reinforcing member 3 and the connecting assembly and the mounting surface. In the embodiment of the application, the reinforcing member 3 is connected with the edge folding plate 2, and in other embodiments, the reinforcing member 3 can also be connected with the corrugated plate 1. The position of the reinforcing member 3 is not limited here.

[0057] Specifically, the mounting surface is a surface for mounting the connecting device. In this embodiment, the mounting surface is a deck surface, and in other embodiments, the mounting surface can also be in other forms, which are not limited here. In the embodiment of the application, the reinforcing member 3 is in a right-angle T-shaped structure. Of course, in other embodiments, the reinforcing member can also be in a rectangular shape and any other polygonal shape that can have a stable structure, as long as it can provide stable support for the connecting assembly.

[0058] The number of reinforcing members 3 is multiple, and the multiple reinforcing members 3 are arranged at intervals along the extension direction of the connecting assembly. The number of reinforcing members 3 is multiple and arranged at intervals along the direction of the connecting assembly, which can provide sufficient support for the connecting assembly and further improve the installation strength of the connecting device to prevent it from shaking.

[0059] As Figure 4 shown, the application also discloses a mounting method of the connecting device, the mounting method is used for mounting the connecting device, and the mounting method comprises the following steps:

[0060] Step S1, placing the corrugated plate 1 on the side protruding from the bending part 21, so that at least part of the corrugated plate 1 is coincided with the projection of the bending part 21 in the horizontal direction;

[0061] Step S2, grinding the first surface 4, so that the shape of the first surface 4 is adapted to the shape of the bending part 21; in this embodiment, in order to adapt the shape of the first surface 4 to the shape of the bending part 21, the first surface 4 can be ground to be away from the concave surface of the bending part 21, thereby increasing the contact area of the corrugated plate 1 and the flanged plate 2, and increasing the connection strength of the corrugated plate 1 and the flanged plate 2;

[0062] Step S3, connecting the first surface 4 and the bending part 21. In this embodiment, the first surface can be connected with the bending part by welding. The corrugated plate 1 is placed in the position coincided with the projection of the bending part 21 in the horizontal direction, and the first surface 4 is ground to be fitted with the bending part 21, and finally the two are connected and welded. Through the above mounting method, the welding work of the corrugated plate 1 and the flanged plate 2 can be efficiently completed, and finally the defect that the connection mode of the corrugated plate 1 and the flanged plate 2 in the prior art is not stable, resulting in a large amount of welding on site and a large accumulated welding stress, so that the corrugated plate 1 is easy to produce secondary deformation is solved.

[0063] As Figure 1 shown, the connecting device further comprises a reinforcing member 3, and the mounting method further comprises: connecting the two ends of the reinforcing member 3 with the connecting assembly and the mounting surface respectively. The two ends of the reinforcing member 3 are connected with the connecting assembly and the mounting surface respectively, so as to finally realize the effect that the reinforcing member 3 provides a sufficient supporting force for the connecting assembly. In this embodiment, the two ends of the reinforcing member 3 are connected with the connecting assembly and the mounting surface respectively by welding.

[0064] Specifically, in order to ensure the perpendicularity of the corrugated plate 1 and reduce the deformation of the segmented corrugated plate 1 as much as possible, the installation of the reinforcing member 3 is divided into the following steps: 1. installing vertical angle steel reinforcement for the corrugated plate 1 and the folded edge plate 2 at the joint, and installing the reinforcing member 3 for the segmented corrugated plate 1. If the segmented corrugated plate 1 is located at the lower end of the total segment, the reinforcing member 3 is removed with the dock; if the segmented corrugated plate 1 is located at the lower end of the non-total segment, the reinforcing member 3 is removed with the total segment; 2. installing diagonal bracing angle steel reinforcement for the T-beam on the deck to prevent deformation during turning, and installing the reinforcing member 3 for the segmented corrugated plate 1. If the segmented corrugated plate 1 is located at the lower end of the total segment, the reinforcing member 3 is removed with the dock; if the segmented corrugated plate 1 is located at the lower end of the non-total segment, the reinforcing member 3 is removed with the total segment; 3. installing channel steel reinforcement for the T-beam on the deck at a distance of 2600mm from the joint, and installing the reinforcing member 3 for the segmented corrugated plate 1 at a distance of 300mm from the edge of the non-framed plate. If the position is the total segment joint, the reinforcing member 3 is removed with the total segment; if the position is the lashing joint, the reinforcing member 3 is removed with the lashing. Through the above operations, the perpendicularity of the corrugated plate 1 during the whole process can be effectively ensured, thereby improving the structural integrity and safety of the ship and greatly reducing the workload of excessive explosives and unnecessary plate replacement.

[0065] Specifically, through the implementation of the process method, the following obvious effects are achieved: first, the problem of excessive heat input due to welding is solved, and the problem of easy deformation of the corrugated plate is reduced as much as possible; second, the perpendicularity and stability of the corrugated plate during the whole process are ensured by installing the reinforcing member. The above method greatly reduces the workload of excessive explosives and unnecessary plate replacement. In summary, the advantages of the present application are: high safety, improved efficiency, suitable for industrial production, high construction precision, and good finished quality.

[0066] Specifically, in the embodiments of the present application, the following matters need attention: correct safety measures need to be maintained during cutting; the cutting tool needs to be maintained regularly to ensure cutting quality; the cutting size must meet the design requirements to ensure the structural integrity.
