Description

[Detailed Description of the Invention] The present invention relates to an improvement in the bonding structure between a honeycomb panel and other members.

A honeycomb panel is a honeycomb core, which is a planar assembly of hollow columns made of thin sheets of aluminum, plastic, paper, etc., and surface plates made of thin sheets of metal, non-metal, etc. are pasted on both cell ends of the honeycomb core. It consists of a structure. Therefore, conventionally, when joining a honeycomb panel to another member, it has been done as shown in FIG. 3. That is, generally, the honeycomb core 13 at the joint part 11a of the honeycomb panel 11 is cut out over a predetermined width, and an insert member 15 made of wood or the like to which a reinforcing plate is attached is inserted into the cutout part 14. A mounting piece 16 provided opposite to a mounting member 16 whose base end is fixed to a member (not shown)
a, 16a sandwich the joint 11a of the honeycomb panel 11, and the mounting pieces 16a, 1
6a and the reinforcing plate of the insert member 15 with rivets 1
A structure in which it was fixed at 7 etc. was used.

Therefore, in the conventional joint structure, firstly, manufacturing the insert member 15 is troublesome, and secondly, depending on the material of the insert member 15, the joint portion 11a may increase in weight, lack strength, etc. Thirdly, it has been pointed out that the insert member 15 is troublesome to attach, requiring a large number of man-hours for joining, and the joining is troublesome.

Regarding the second problem mentioned above, it has been considered to reduce the weight of the joint by using other joint structures that use insert members with hollow parts, but the joint strength of the joint may not be sufficient. In order to increase the height without increasing the height, it is necessary to particularly increase the wall thickness and plate thickness of the insert member, etc., and it is still pointed out that the weight of the joint increases. However, it has been pointed out that manufacturing and joining are troublesome.

The present invention was developed in view of the above-mentioned circumstances, and its technical means are as follows. That is, it is a joining structure in which a honeycomb panel, in which a face plate is joined to both cell end faces of a honeycomb core, is joined to another member, and the joining part of the honeycomb panel is
The mounting member fixed to the other member is clamped by a mounting piece provided facing the mounting member. At the same time, a reinforcing plate is clamped between both surface plates and both cell end surfaces of the honeycomb core at the joint portion of the honeycomb panel so that both cell end surfaces of the honeycomb core in the honeycomb panel and their outer surfaces are substantially flush with each other. However, the reinforcing plates and the mounting pieces of the mounting member located in a positional relationship corresponding to the reinforcing plates on both the front plates are fixed to each other with rivets, bolts, or the like.

By using such technical means, the present invention makes it possible to join without using an insert member, etc., firstly, it is easy to manufacture, and secondly, it eliminates the increase in weight and lack of strength. Thirdly, the purpose is to propose a joining structure for honeycomb panels that is easy to join and can eliminate the difficulties caused by conventional joining via insert members, etc. That is.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

FIG. 1 is a longitudinal cross-sectional view of essential parts showing an embodiment of a honeycomb panel joining structure according to the present invention. In the figure, 1 is a honeycomb panel, and this honeycomb panel 1 has a honeycomb core 3 formed of aluminum, plastic, paper, etc. as a core material, and metal and non-metal plates are attached to both cell end faces of this honeycomb core 3. It is constructed by attaching surface plates 2, 2 made of thin plate materials such as, respectively.

Then, notch steps 7, 7 are formed on both cell end faces of the honeycomb core 3 at the joint 10 of the honeycomb panel 1.
is formed, reinforcing plates 6, 6 are sandwiched between the notched step portions 7, 7 and the surface plates 2, 2, respectively, and are opposed to a mounting member 16 whose base end is fixed to another member (not shown). The joint portion 10 of such a honeycomb panel 1 is fitted and clamped by the mounting pieces 16a, 16a which are protruded from each other. It is configured to be fixed. As shown in the figure, the reinforcing plates 6, 6 are formed to have dimensions such as the same width as the notch steps 7, 7, and are arranged substantially flush with the cell end surface on the honeycomb core 3 main body side.

FIG. 2 is a longitudinal cross-sectional view of the main parts showing another embodiment of the present invention. In the embodiment shown in FIG. 2, the reinforcing plates 6, 6 sandwiched between the surface plates 2, 2 and the honeycomb core 3 at the joint 10 of the honeycomb panel 1 are
By forming buckling parts 3a, 3a on the cell end face of the honeycomb core 3 at that part, the sandwiching is performed,
In addition, bolt insertion holes are bored in the joint portion 10 of the mounting pieces 16a, 16a of the mounting member 16 and the honeycomb panel 1, so that the mounting pieces 16a, 16a can be inserted as shown in the figure.
The reinforcing plates 6, 6, etc. are fixed to each other by bolts and nuts 9a. In other words, in the joining structure shown in FIG. 2, unlike the intervening means of the reinforcing plates 6, 6 shown in FIG. 1, the cutout steps 7, 7 are not formed. Reinforcing plates 6, 6 are attached in advance to predetermined parts of the lower surface, and when bonding the top plates 2, 2 to the honeycomb core 3 under pressure, the cell end faces of the honeycomb core 3 in the parts corresponding to the reinforcing plates 6, 6 are attached. By forming buckling portions 3a, 3a in the honeycomb panel 1, the reinforcing plates 6, 6 are fixed in a predetermined manner between the honeycomb core 3 and the surface plates 2, 2 at the joint 10 of the honeycomb panel 1. Therefore, according to this embodiment, it is not necessary to form the cutout steps 7, 7 in the honeycomb core 3 in order to attach the reinforcing plates 6, 6, so that it is possible to reduce the number of manufacturing steps for the joint part 10. be.

As detailed above, according to the honeycomb panel joining structure of the present invention, when joining the honeycomb panel and other members, the joining portion of the honeycomb panel can be joined without using a separately molded insert member or the like. Since this has become possible, the types of difficulties that conventionally occurred due to joining via insert members etc. have been eliminated.

That is, firstly, no insert member or the like which is separately molded and complicated to manufacture is used, and the structure of joining the honeycomb panel with other members is easy to manufacture.

Second, both increased weight and insufficient strength are eliminated. In other words, in this joint structure, the honeycomb core and the mounting members on other parts are joined almost directly, although with a slight reinforcing plate, etc., so a strong and high joint strength can be obtained despite a slight increase in weight. . In other words, without using insert members etc.
A light and strong joint structure is realized, and the honeycomb panel and other members are firmly joined by a joint having higher strength than the honeycomb panel.

Thirdly, the joining operation can be easily performed without any trouble by sandwiching and joining the joined portion of the honeycomb core to the mounting piece of the mounting member on the other member side.

As described above, the effects of the honeycomb panel joining structure according to the present invention are remarkable and significant.
