Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a honeycomb panel, and particularly to a honeycomb panel to which various parts can be easily attached.

[Prior Art] Conventionally, a honeycomb panel A1 has face plates A3 and A4 on both sides of a honeycomb core A2, as shown in FIG.
Face plates A3 and A4 coated with brazing materials A5 and A6 are placed on both sides of a honeycomb core A2, and are joined together by heating. In this type of honeycomb panel A1, a fixing member A7, such as a cylindrical nut base material, is usually arranged between the double-sided plates A3 and A4 in order to attach various members such as bolts. In order to fix this fixing member A7 inside the honeycomb panel A1, the double-sided plate A
3. Before joining A4, first make a space A8 at a predetermined position of the honeycomb core A2, then place the honeycomb core A2 on one face plate A3, and place the fixing member A7 in the space A8. After that, cover with the other face plate A4, then double-sided plates A3 and A4
This is done by joining the steps.

[Problem to be solved by the invention] However, the fixing member A7 is simply placed in the empty space A8 of the honeycomb core A2 before joining, and therefore the face plate A is placed on both sides of the honeycomb core A2.
3. When joining A4, there was a problem that it would shift from the predetermined position. Therefore, conventionally,
In consideration of this deviation, it was necessary to use a fixing member A7 that was considerably larger than the required size.

An object of the present invention is to solve the above-mentioned problems and provide a honeycomb panel that can suitably position a fixing member.

[Means for Solving the Problems] In other words, the present invention has been made to achieve the above object.Face plates are joined to both sides of a honeycomb core, and a hollow space in which no honeycomb core is formed is provided in a part of the honeycomb core. In a honeycomb panel in which a fixing member to be joined to the face plate is disposed in the cavity, a positioning means for connecting the face plate and the fixing member is provided between the face plate and the fixing member, and a recess and a fixing member are provided between the face plate and the fixing member. The gist of the present invention is a honeycomb panel characterized by having a structure consisting of a convex portion that fits into a recess.

Here, the honeycomb core is not only a normal honeycomb-shaped core material, but also a core material composed of cells of various shapes such as triangular and quadrangular.

The above-mentioned face plate may be made of a plate material (JIS standard
BA11PC, BA12PC) etc. can be used.

As the fixing member, for example, a cylindrical or prismatic nut base material made of aluminum alloy (JIS standard 6063) can be used.

Further, the recess of the positioning means is a recessed portion formed in one or both of the face plate and the fixing member, and this recess may penetrate to the opposite side to form a through hole.

Furthermore, the convex portion of the positioning means fits into the recess described above to connect the face plate and the fixing member, and may be provided integrally with the face plate or the fixing member, or may be made of a pin material or the like. It may also be provided separately.

As a combination of the above-mentioned recess and protrusion, for example, a through hole is formed in one face plate, a recess with a bottom is further provided in the fixing member, and a pin material is fitted into the through hole and the recess for positioning. You may do so. Alternatively, through holes may be formed in both face plates, through holes may also be provided in the fixing member, and pin materials may be fitted into both through holes.

Furthermore, a convex portion may be formed integrally with the fixing member, and the convex portion may be fitted into a through hole formed in the face plate. Alternatively, a concave portion may be formed in the fixing member and a convex portion may be formed in the face plate for fitting.

[Function] A part of the honeycomb core sandwiched between the face plates of the honeycomb panel is provided with a space where no honeycomb core is formed, and a fixing member to be joined to the double-sided plate is arranged in this space. . A positioning means having a recess and a protrusion is provided between the face plate and the fixing member, and by fitting the protrusion into the recess of the positioning means, the face plate and the fixing member are fixed. The members are connected, and the fixing member is positioned.
