I-shaped internal connection interlayer connection structure

Technical Field

The utility model relates to a I-shaped inscription intermediate layer connection structure belongs to boats and ships equipment field.

Background

As ships carry more and more heavy equipment, these place higher demands on the load carrying capacity of the ship. At present, more and more countries are beginning to focus on the research on the lightweight of ships, so as to replace the traditional reinforced plate structure with some novel structures with light weight and high bearing capacity, and the steel sandwich structure is one of the objects of more research.

Compared with the traditional plate frame structure, the sandwich plate frame structure can better bear the uniformity (in longitudinal and transverse directions) of out-of-plane load, so that the load action position is not very determined, and the load with locality, peaking property and instantaneity, particularly heavy load, can show better advantages. Such as ship or aircraft landing decks, lift platforms, vehicle decks, etc., all have this load characteristic. Studies have shown that sandwich structures should provide significant weight savings and control of vibration compared to conventional structures, and have found many applications in europe, the united states, and the like.

As shown in fig. 1 and 2, the sandwich plate frame structure is composed of a sandwich structure upper plank 1, a lower plank 2, a core layer web 3, a deck longitudinal girder 4 and a deck strong beam 5. Since the sandwich structure is generally thin, conventional welding techniques are not suitable for welding such thin plates, and thus the sandwich structure module is usually manufactured by using laser welding techniques. However, the laser welding technology has high requirements on welding equipment, and the size of the sandwich structure modules capable of being produced in batches is limited, so that when the sandwich structure is applied to a large area of a ship deck or a platform, the sandwich modules need to be spliced, the processing capacity of the laser welding equipment is limited, the width or the length of the sandwich structure modules is limited, the sandwich structure is sometimes not enough to span the width or the length of the whole plate frame, and the sandwich plate lattice structure needs to be connected with the sandwich plate lattice structure by using a connecting structure.

Under the background, considering the reliability and feasibility of implementation, it is a current technical problem how to weld the sandwich structure according to the characteristics of the sandwich structure itself, so that the sandwich structure modules can form effective connection and good force transmission.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: how to effectively connect the sandwich structure modules and facilitate the transmission of force.

In order to solve the technical problem, the utility model provides a I-shaped inscription intermediate layer connection structure is provided, including intermediate layer grillage structure, its characterized in that connects through connecting plate structure between the intermediate layer grillage structure, and connecting plate structure includes top panel, lower panel and web.

Preferably, the sandwich plate frame structure comprises an upper plank, a lower plank, a core web, a deck longitudinal girder and a deck strong cross beam, wherein the upper plank is fixedly connected with the lower plank through the core web.

Preferably, the deck longitudinal girders and the deck strong cross beams are distributed and connected in a staggered manner to fix the sandwich plate frame structure.

Preferably, the connecting plate structure include top panel, lower panel and web, the top panel is connected the last bed board on two intermediate layer grillage structure upper portions, the lower bed board of two intermediate layer grillage structure lower parts is connected to the lower panel, the top panel passes through the web and is connected with lower panel.

Preferably, the connecting plate structure is in an I-shaped structure and is connected with the two sandwich plate frame structures.

Preferably, the upper plank and the lower plank of the sandwich plate frame structure are connected in a welding structure.

Preferably, a plate gap is formed between the two upper planks connected with the upper panel, and the distance b1 between the plate gaps is 20 mm.

Preferably, a plate seam is arranged between the two lower planks connected with the lower panel, and the distance b2 between the plate seams is 20 mm.

Preferably, the web structure is parallel to the arrangement direction of the core web.

Preferably, the connecting plate structure is kept continuous at the deck strong beam, and the web plate of the deck strong beam is provided with an opening which is welded with the connecting plate structure, so that the welding corners fill the opening.

The utility model discloses can effectual messenger this internal connection sandwich layer connection structure can be on taking into account production technology's basis, connection problem between the effectual processing sandwich structure module, the problem is arranged to the grillage of the deck of solving because of sandwich structure module size is limited and bringing.
