Description

[Detailed description of the invention] The present invention relates to a joining structure of box-shaped members in which box-shaped panel members are attached to each other or to studs in order to assemble, for example, walls and partitions of showrooms, stores, etc. It is something.

Conventionally, when joining this type of box-shaped members,
A latching hook protruding from one side is inserted and locked into a slit formed on the other side, or a bolt is inserted from the inside of the box-shaped panel between the two and tightened. However, in the case of the former, it is necessary to weld the base or lock the hook in the slit in order to protrude and fix the hook to the side end surface of the box-shaped member, and it is necessary to attach at least two hooks at one location. If the panel is not attached, a reliable connection without lateral wobbling will not be possible, and it is not very desirable that the hook protrudes from the side end surface of the panel when it is being carried or transported. In the latter case, if the inside width of the box-shaped panel is wide, it will be easy to work, but if it is narrow, it will be very labor-intensive, and in any case, it can only be tightened and fixed within the range that can be inserted with your hand, so the vertical width Some have the disadvantage that the middle edge cannot be fixed.

An object of the present invention is to provide an improved joining structure for box-shaped members in order to eliminate such drawbacks.

In other words, in the joining structure of box-shaped members according to the present invention, the sides are connected by inserting the slits formed in the side end faces of the box-shaped member with the flat plate material from which protruding latching claws are oriented upwardly and downwardly on the left and right sides. Each box-shaped member is joined by locking the thick end face portion.

This will be explained below based on the illustrated embodiments.

Architectural members to which this joint structure is applied include panel members A ₁ and A ₂ that are a combination of at least planar members a ₁ and a ₁ and side end surface members a ₂ , and studs ( It is a hollow box-shaped member such as (not shown). These joining end surfaces may be either parallel to each other so that the members are joined in a straight line, or obliquely opposed so that the members are joined at right angles.

A flat plate material 1, which is formed to have the same length and width as the end surfaces, is interposed between the side end surfaces of each member. The flat plate material 1 is made of straight steel with a certain thickness, and latching claws 2 and 3 are provided on the left and right sides of the plate surface, projecting in opposite directions. In the illustrated embodiment, L-shaped latching claws 2 and 3 are provided at the top and bottom by cutting and bending the plate surface, and their protruding dimensions are the same width as the wall thickness of each side end surface of panel members A ₁ and A ₂ . It is formed. Further, a plurality of pairs of left and right latching claws 2 and 3 are provided at regular intervals along the longitudinal direction of the flat plate material 1. On the other hand, panel material A ₁ ,
_A2 is provided with slits 4 and 5 on the side end surface in correspondence with the respective latching claws 2 and 3. The slits 4 and 5 are formed to have a size that allows the locking claws 2 and 3 to fit into them, and each panel member ₁ ,
It is provided at a position where the upper and lower ends of _A2 can be aligned.

When using this flat plate material 1, the flat plate material 1 is first fixed to the side end surface of the panel member _A1 by inserting and locking the downwardly projecting hook 2 into the panel member _A1 on one side through the slit 4. . Next, panel members
Panel member A ₂ can be attached to flat plate 1 attached to A ₁ by locking the slit 5 of panel member A ₁ with upwardly formed locking claws 3.

In the joint structure of box-shaped members configured in this way,
The latching claws 2 and 3 are inserted into the slits 4 and 5 so as to sandwich the flat plate 1, and the thick side wall portions of the box-shaped members A ₁ and a ₂ are locked, thereby being joined and fixed to each other. The latching claws 2 and 3 are connected to the box-shaped member A ₁ ,
It protrudes by the width of the side wall of _A2 and does not have a large standing dimension, so it does not pose a problem when being carried. In addition, each of the locking claws 2 and 3 is formed so as to bend the flat plate material 1 and lock the wall thickness of the side walls of the box-shaped members _A1 and _A2 . Even if it is, the box-shaped member can be securely fixed without causing any left-right wobbling. Furthermore, each box-shaped member
Since A ₁ and A ₂ can be fixed by simply hooking them onto the hooks 2 and 3 of the flat plate material 1, they can be easily fixed over their entire vertical width and can also be easily removed.

Note that the flat plate material 1 interposed between the box-shaped members A _{1 and} A ₂ is used, for example, when pasting the decorative sheets b ₁ and b ₂ on the flat surfaces of the panel members A 1 and A ₂ . When it is rolled up into the receiving frames c ₁ and c ₂ attached to the corners of A ₁ and A ₂ , the thick portion can be hidden so that it cannot be seen from the outside.

As described above, according to the joining structure of box-shaped members according to the present invention, it is possible to easily assemble and disassemble the members, and to securely join and fix them without causing any trouble in transportation.

[Scope of utility model registration request] When joining panels each formed in a box shape to each other or to a stud between their respective side end faces, an L-shape protruding from the left and right sides of the flat plate with an amount equal to the wall thickness of the side end faces of the box-shaped member is oriented upside down. The box-shaped members are joined to each other via the flat plate material by inserting the hooks into slits formed on each side end face of the box-shaped member and locking the thick side end faces. Features a joining structure of box-shaped members.
