2. Description of the Related Art There is a well-known example of "framework by connecting support members", in which a stand, stage, etc. can be easily temporarily installed and quickly disassembled after use, and it is widely used. In those known examples, the pillar members are bolted together to form a skeleton having a required shape, or a notch hole formed in one member is provided with a locking piece of the other member. It has a structure in which it is inserted and connected, and it is assembled before use and quickly dismantled and collected after use.

[0003]

In the case of the above conventional structure, the former bolt tightening structure requires a large number of steps for assembling work by tightening the bolts and disassembling work by removing the bolts. Large items such as stages have the drawback that the construction period for assembly and setup will be long, and that there will be spots where the bolts are not properly tightened, and the stand or stage may rattle or creak. There are performance drawbacks such as discomfort, and there is a risk that the stand stage may collapse due to disconnection due to improper bolt tightening.

On the other hand, the latter plug-and-connect structure has
Only by inserting and connecting it, it is not possible to accurately fix the connecting part, and the problem of "rattle and creaking" occurs as well, so bolting and fixing to the important parts of the connecting part using auxiliary members such as fixing brackets. Similar to the above-mentioned bolt tightening structure, it requires a great deal of labor and construction time, and there is a possibility that "rattle", "creak" or collapse may occur due to improper tightening and fixing of the auxiliary member. is there.

The present invention provides a skeleton body that solves the above-mentioned problems of the prior art.

[0006]

The framework of the rod member according to the present invention which solves the above technical problems is as follows: "The inner piece on the column wall side is a vertical piece, and the outer piece facing the inner piece is in the vertical direction. The locking pocket has a substantially U-shaped locking pocket that is inclined to the upper side and has a narrower upper width and a lower width. The combination of the locking projections that face the fitting portion, which is tightly fitted and inserted from above, with the beam members protruding at both ends, and interconnects the strut members and the beam members of arbitrary size and number. It has a structure to do.

The above-mentioned strut members and beam members are mainly made of pipes for the purpose of reducing the weight, and a screw jack for adjusting the level and level of the frame is attached to the lower end of the strut members. If necessary, a separate intermediate beam member that connects the middles of the beam members connected to the strut member is provided, and the interlocking between the intermediate beam member and the beam member is such that the locking pocket and the locking projection are connected. Apply structure.

[0008]

The skeleton body of the present invention having the above-described structure is composed of the column member having the locking pocket and the beam member having the locking projection provided with the fitting portion for tightly fitting and fitting the locking member. Since it consists of a combination, by connecting both of them together, it is possible to freely assemble a frame structure in which beam members are horizontally installed and connected between upright columns, and it is extremely easy to disassemble by removing the locking projections. This makes it possible to eliminate complicated bolt tightening and fixing of auxiliary members in the conventional structure.

The locking pocket and the locking projection are
Since it has the above-mentioned shape requirements, the locking projections are simply inserted from above the locking pockets, and the mutual connection and fixation are accurate, and due to the shape characteristics of the assembled framework, the locking is achieved. Since the tight fit of the pocket and the locking projection is improved, the skeleton has a very stable assembly posture against external forces in the three axial directions, and is used for stages and stands that receive heavy loads. However, if the mechanical strength of the strut member and the beam member is made to be required, there is no fear of creaking, rattling, posture collapse, and the like.
