Description

Technical Field

[0001] The utility model relates to the field of aluminum honeycomb panels, and more specifically, to a spliced aluminum honeycomb panel. Background Art

[0002] Honeycomb aluminum panels are a series of metal composite panel products developed by combining the composite honeycomb panel technology of the aviation industry. The panels adopt a "honeycomb sandwich" structure, that is, high-strength alloy aluminum plates with a weather-resistant decorative coating on the surface are used as the top and bottom plates, and are compounded with an aluminum honeycomb core under high temperature and high pressure to form a composite panel. In order to facilitate the production and installation of aluminum plates, the sizes of common aluminum honeycomb panels on the existing market are fixed. Therefore, when in use, the aluminum honeycomb panels need to be spliced to meet the installation requirements of large areas. A kind of environmentally friendly spliced aluminum alloy honeycomb core panel (patent publication number: CN216305129U) is disclosed in the prior art, and splicing is achieved by the cooperation of concave-convex and bolts on the upper and lower surfaces. However, this method requires operations on both sides of the panel respectively, which results in a large size of the assembled panel and is not conducive to installation. Moreover, for the subsequent thickness of the inner and outer panels, setting grooves and panels on its surface will result in limited strength after docking, affecting the strength of the splicing part.

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0020] Example:

[0021] See also Figures 1 - 3 As shown, a spliced ​​aluminum honeycomb panel includes a composite panel A1 and a composite panel B2. The composite panel A1 includes a panel 3, a honeycomb core 5 and an inner panel 4 from top to bottom. The composite panel A1 and the composite panel B2 have the same layered structure from top to bottom. The composite panel A1 also includes an extension plate 6 arranged outwardly on one side of its top panel 3. The extension plate 6 is placed on the side of the composite panel A1 close to the composite panel B2. The composite panel B2 also includes a notch 7 opened on one side of its top panel 3. The internal dimensions of the extension plate 6 and the notch 7 are adapted to enable the composite panel A1 and the composite panel B2 to be butted together when butt-jointed. At this time, the end faces of the two inner panels 4 are in contact, and the two panels 3 are staggered to form a concave-convex matching structure. Plate A1 is flush with composite plate B2, and positioning holes 61 are symmetrically provided on both sides of the surface of extension plate 6. A boss 8 is symmetrically provided on one side of the upper surface of inner plate 4 of composite plate B2, and boss 8 corresponds to notch 7. Boss 8 is at the same height as honeycomb core 5, so as to support extension plate 6 after splicing to maintain the strength of extension plate 6. Positioning bolt 9 is fixed on the top of boss 8, and positioning bolt 9 is matched with the inner size of positioning hole 61. Positioning bolt 9 is flush with the upper surface of composite plate B2, so that positioning hole 61 is docked with positioning bolt 9 from top to bottom during docking, so as to realize preliminary installation and fixation. Composite plate B2 is fixed first during splicing, and then composite plate A1 is spliced ​​to improve the convenience during splicing.

[0022] Please refer to Figure 2 and Figure 3 As shown, a locking internal threaded hole 91 is provided on the upper surface of the positioning bolt 9, and a fixing bolt 10 is symmetrically arranged on one side of the surface of the panel 3 of the composite board B2 close to the notch 7. A rotating plate 11 is installed on the surface of the fixing bolt 10 to adjust the position of the rotating plate 11 during splicing. The two rotating plates 11 span the docking line of the composite board A1 and the composite board B2. When the locking bolt 12 is fixed, the rotating plate 11 is effectively fixed, which satisfactorily improves the strength of the splicing. The locking bolt 12 is vertically penetrated at one end of the rotating plate 11 away from the fixing bolt 10.

[0023] The bottom end of the locking bolt 12 is matched with the inner size of the locking internal threaded hole 91, and fixation is achieved through the cooperation of the two.

[0024] Please refer to Figure 2 and Figure 3As shown, on the upper surface of the panel 3 of the composite board B2, limiting bumps 13 are symmetrically arranged on one side close to the notch 7 to limit the rotation plate 11 during rotation. When the rotation plate 11 is perpendicular to the splicing line, the limit can be obtained to provide the accuracy of docking.

[0025] Working principle: When the composite board A1 and the composite board B2 are docked, first ensure that the two rotation plates 11 rotate towards the side close to each other, and then install the extension plate 6 from top to bottom in docking with the notch 7, so that the positioning bolt 9 can be placed inside the positioning hole 61. At this time, the center of the extension plate 6 is supported by the honeycomb core 5 inside the composite board B2, and both ends of the extension plate 6 are supported by the end faces of the bosses 8 to ensure the stability of the connection between the composite board A1 and the composite board B2. Then rotate the rotation plate 11 so that the rotation plate 11 straddles the docking line between the composite board A1 and the composite board B2. When the rotation plate 11 is perpendicular to the docking line between the composite board A1 and the composite board B2, it is limited by the outer limiting bumps 13. At this time, the locking bolt 12 corresponds to the position of the positioning bolt 9, and the bottom of the locking bolt 12 can be rotated into the locking internal thread hole 91 by rotating the locking bolt 12, thereby realizing the effective splicing of the composite board A1 and the composite board B2. The two rotation plates 11 straddling outside the docking line can increase the splicing strength of the composite board A1 and the composite board B2.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
