Assembly of the second joint fitting Ba provided (attached) on the beam B side with respect to the first joint fitting Aa while preventing the attachment piece 1, ie, the first joint fitting Aa, from rotating due to a slight gap (clearance) between them This is because the operation is performed smoothly (when the second joining bracket Ba is assembled to the first joining bracket Aa, if the first joining bracket Aa moves, that is, rotates, the workability is hindered).

  The beam B is provided with a longitudinal groove 32 at the center of the end face joined to the side surface of the column P, which is sufficient to fit the entire portion of the first joint fitting Aa protruding from the side surface of the column P. A guide hole 130 for the screw bolt 111 is formed in the center of the back wall 32a so as to correspond to the pair of upper and lower bolt holes 113, 113 provided in the second joint fitting Ba. Then, the attachment piece 21 of the second joint fitting Ba is engaged with the vertical groove 32 of the beam B, and the bolt hole 113 and the guide hole 130 are made to coincide with each other, so that the rear wall 32a of the vertical groove 32 is formed. When the screw bolt 111 is screwed into the guide hole 130 through the bolt hole 113, the second joint fitting Ba is assembled and fixed to the beam B while being engaged in the vertical groove 32.

  Then, when the assembled beam B is assembled to the side surface of the column P and the second joint fitting Ba is lowered from above the first joint fitting Aa so as to be engaged with the inside of the first joint fitting Aa, While the one joining metal Aa is engaged with the inside of the longitudinal groove 32 of the beam B (the assembly piece 24 of the second joining metal Ba, that is, the second joining metal Ba is between the assembly pieces 4 and 4 of the first joining metal Aa. While being engaged, the beam B descends, and finally, the neck portion of the hook-shaped hooking piece 7 is engaged with the notch 6, and the tip is between the receiving piece 3 and the column B due to the presence of the spacer 2. The second joint fitting Ba on the beam B side and the first joint fitting Aa on the column P side are combined with each other by engaging with the gap a to be formed. By inserting the drift pin 12 into the through-hole 33 provided laterally on the column B side into the insertion holes 14 and 114 arranged to coincide with each other in this combined state, the beam B is made to the column P. Can be joined.

Second Embodiment The second embodiment is shown in FIG. 6 to FIG. 8, and as is apparent from these drawings, the first joint metal fitting Ab of the second embodiment is the same as the first joint metal fitting Aa of the first embodiment. Since the structure is almost the same and only the amount of protrusion of the spacer piece 2 from the mounting piece 1 is changed, the remaining points are substantially the same as in the first embodiment as shown by the same reference numerals, and the description thereof is omitted.

  The reason why the width of the spacer piece 2 protruding from the mounting piece 1 is wider than that of the first embodiment is that a concave portion (hole) 39 is provided on the side surface of the column P (FIGS. 6 and 7). The mounting piece 1 is fitted to the column P, and is fastened to the column P by the screw bolt 11 so that the first joint fitting Ab can be mounted on the column P in a more stable manner.

  Therefore, there is no structural inconvenience even if the first joint fitting Ab of the second embodiment is applied instead of the first joint fitting Aa of the first embodiment (although the recessed portion 39 is provided in the column P anyway). As).

  The second joint fitting Bb of the second embodiment (the same parts as those of the second joint fitting Ba of the first embodiment are denoted by the same reference numerals) are arranged along the longitudinal direction of the center longitudinal base piece 34 and the attachment piece 34. A mounting piece 221 is projected at the center of the outer surface of the base piece 34 of the groove-like frame body in plan view, which is composed of an assembly piece 24 which is bent at both ends and is opposed to each other. The through holes 113A for inserting the drift pins 112 for fixing the pieces 221 to the beams B are provided in the vertical direction, and the assembled pieces 24, 24 are the drift pins that coincide with each other between the assembled pieces 24, 24. .. Are provided side by side in the vertical direction, and a hook-like hooking piece 7 is provided at one end of the assembly piece 24 in the vertical direction on the free end side. That is, the second joint fitting Bb of the second embodiment has the bolt hole 113 formed in the groove-shaped attachment piece 21 in which the attachment means to the beam B of the object of the first embodiment is composed of the assembly piece 24 and the attachment piece 21. The mounting piece 221 is provided on the outer surface of the base piece 34 corresponding to the mounting piece 21 of the second joint fitting Bb, and the mounting piece 221 is utilized through the through-hole 113A. The only difference is that the drift pin 112 is fixed to the beam B, and the remaining points are not different from those of the second joint fitting Ba of the first embodiment.

  Therefore, there is no problem even if the second joint fitting Bb of the second embodiment is applied in place of the second joint fitting Ba of the first embodiment. Instead, there is no problem even if the first joining metal fitting Aa of the first embodiment is used and the second joining metal fitting Ab of the first embodiment is used instead of the second joining metal fitting Bb of the second embodiment.

  Then, the mounting piece 1 of the first joint fitting Ab is engaged with the recessed portion 39 formed on the side surface of the column P, and the screw bolt 11 is screwed into the guide hole 30 through the bolt hole 13 as in the first embodiment. When tightened, the first joining bracket Ab is assembled and fixed to the column P.

  And, on the end face of the beam B, the longitudinal groove 32 sufficiently formed to engage the first joining metal fitting Ab protruding from the column P and the slit groove 32b provided in the center of the rear wall 32a of the longitudinal groove 32, The second joint fitting Bb is accommodated in the beam B so that the assembly piece 24 side engages with the longitudinal groove 32 and the attachment piece 221 engages with the slit groove 32b. The second joint fitting Bb is assembled to the beam B by fitting the drift pin 112 into the through hole 113A through the through-hole 333 previously provided in the beam B so as to match. Then, when the second joint fitting Bb attached to the beam B is lowered from the upper side of the first joint fitting Ab projecting on the column P as the beam B is lowered, the latch piece 7 of the second joint fitting Bb becomes the first. The joint 6 is engaged with the notch 6 of the metal fitting Ab, and the tip thereof is engaged with the gap a formed between the receiving piece 3 and the column D due to the presence of the spacer 2, and the second joint metal Bb on the beam B side. And the first joining metal fitting Ab on the column P side are combined with each other. In this combined state, as in the first embodiment, the drift pin 12 is inserted into the through-hole 33 in which the beam B side is horizontally provided in the insertion holes 14 and 114 that are arranged to coincide with each other. Thus, the beam B can be joined to the column P.

  In order to fix the first joining brackets Aa and Ab to the pillar P, the screw bolt 11 is used in the embodiment, but the guide hole (the diameter of the screw bolt is smaller than that of the screw bolt and the screw bolt is screwed together). Instead of this, a through hole is provided in the column P, and a tightening bolt is passed through the through hole through the first joint fittings Aa and Ab, and a tightening nut is screwed onto the tip of the tightening bolt protruding from the through hole. You may do it.

  In each embodiment, the beam B is lowered with respect to the first joint fittings Aa and Ab, and the second joint fittings Ba and Bb are assembled to the first joint fittings Aa and Ab. The second joining brackets Ba and Bb are attached to the beam B so that the direction of the latching piece 7 of the embodiment is reversed, and is raised toward the first joining fittings Aa and Ab existing on the column P, and the latching piece 7 is engaged with the notch 6 (the latching piece 7 is locked to the notch 6 so as to restrict the rise, so that the positioning function is performed). There is also a usage in which the beam B is joined to the column P by inserting. In this case, since a new beam can be assembled to the column P below the existing beam (old), it is effective for application to beam replacement (building reform).

  The taper shape in which the lower portions 24a of the assembly pieces 24, 24 of the second joint fittings Ba, Bb are gradually brought closer to the lower end makes it easier to engage the first joint fittings Aa, Ab with the inside thereof. Because.
