Abstract

PURPOSE:To prevent a horizontal material from horizontal swinging and a sure joint thereof by mounting a hook piece installed to one end of a horizontal material to an engagement hole on a peripheral surface of a vertical material and fitting a projected strip into a recessed hole. CONSTITUTION:A recessed surface 3 is vertically installed to four sides of an outer peripheral part of a vertical material while a projected strip 4 is vertically installed to the central part in one piece with the recessed surface 3. A pair of right and left engagement holes 5 are intermittently installed in a file on the recessed surface on both sides of the projected strip 4. Both hook pieces 6c, which extend from both side plates 6a, are projectingly installed to one end of the horizontal material while a notched recessed hole 6d, which is fitted into the projected strip 4 of the vertical material, is bored in the central part of the end face of upper and lower partition walls 6b. When both hook pieces projectingly installed to the end of the horizontal material is engaged with both right and left engagement holes on both sides of the recessed part of the vertical material, the notched recessed hole installed to the end face of the horizontal material fits in the projected strip in the central part of the recessed surface of the vertical material. This construction makes it possible to prevent definitely the horizontal material from horizontal swinging since both members are joined with each other on the joint surface and the projected strip fits into the notched recessed hole.

A hollow strut in which a longitudinal groove is formed on the peripheral surface and a large number of engaging holes are provided vertically in the inner end wall at substantially constant intervals, and the engaging hole is formed in the rear edge fitted into the concave groove. A lock-like locking piece to be hooked is provided, and a connector formed by projecting a screw rod on the front side, a tightening nut screwed to the screw rod, and a hollow beam member having an end surface in contact with the column peripheral surface, The hollow beam member is an assembly frame set in which the insertion and operation hole of the tightening nut screwed into the screw rod of the connector inserted in the hollow portion is transparently provided on the flank near the end face. " An example diagram is shown in FIG. As for the method of assembling the frame set, according to the description in the lower right column of the detailed description of the specification, "To assemble the assembly frame by each member, the connector 5 is inserted from both end faces of the hollow beam member 11 into the hollow portion. Insert the screw rod 8 of the
The flat plate portion 6 is supported by 4, 14 and the end of the screw rod 8 is applied to the tightening nut 9 inserted from the insertion / operation hole 13 and then the tightening nut 9 is rotated and screwed. After that, the hollow beam members 11 are inserted into the concave grooves 2 of the hollow columns 1 and 1 on both sides.
The flat plate portion 6 of the connector 5 protruding from the fitting portion is fitted and the locking piece 7 is hooked in the engagement hole 4 (hereinafter omitted). " In addition, it is irrational that the composition and composition of each member are complex and diversified, and the manufacturing and processing costs thereof are large.

[Means for Solving the Problems] When joining one end of a horizontal member to the peripheral surface of a vertical member, each of the peripheral members of the vertical member is formed in an arbitrary shape such as four-sided, six-sided or other multi-sided, cylindrical surface. On the peripheral surface part, an appropriate number of uneven surfaces in which convex ridges are projected in the central part of the concave surface are vertically arranged, and a pair of left and right hooking holes are intermittently tandemly arranged at both concave surfaces on both sides of the convex ridge. Both hook members that engage with the hooking holes of the horizontal member are oppositely provided on the end face of the horizontal member, and a concave hole that is fitted to the convex strip of the vertical member is formed on the end face of the intermediate member of the horizontal member. It is configured to be joined by hooking the end portion on the uneven peripheral surface of the vertical member.

[0005]

[Operation] Both the left and right hooking holes on both sides of the concave portion of the vertical member are engaged with both hook pieces protruding from the end portion of the horizontal member, and the end portion of the horizontal member is recessed into the ridge at the center of the concave portion of the vertical member. Since the notch concave hole is engaged, both members at the hooking joint surface are in close contact with each other, and the transverse notch of the transverse member is prevented by the engagement of the notch concave hole to the ridge.
