DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment embodying a joint structure of a structural material according to the present invention will be described below with reference to FIGS. In the present embodiment, a joining structure in the case where a tubular column 12 also made of a laminated material is joined to a beam 11 made of a laminated material via a T-shaped bracket 13 will be described. As shown in FIG. 1, the upper surface of the beam 11 is
Two screw bolts 15 are embedded. As shown in FIG.
About ３ is a tapered screw thread portion 15a, and about 後方 of the rear portion is a male thread portion 15b. A guide hole (not shown) is formed on the upper surface of the beam 11 at a position where each screw bolt 15 is embedded, and each screw bolt 15 is screwed into the beam 11 along the guide hole by a bolt screwing device (not shown). . Each screw bolt 15 is screwed in until the entire screw thread portion 15 a is buried in the beam 11, and the male screw portion 15 b projects in a projecting manner on the upper surface of the beam 11. As shown in FIG. 1, a T-shaped bracket 13 made of a rolled steel material is composed of a substantially square base plate 16 as a fixed plate and a substantially square standing plate 17 as an insertion plate piece. One side of the substrate 16 has the same size as the thickness S of the beam 11. The erecting plate 17 extends laterally from the center thereof so as to be orthogonal to the horizontally arranged substrate 16 and has a substantially T-shape as a whole. In a state where the T-shaped bracket 13 is mounted on the beam 11, the upright plate 17 extends upward to have an inverted T-shape. Four first through holes 18 corresponding to the four screw bolts 15 are formed near each corner of the substrate 16. Two second through holes 19 are formed near the upper corner of the standing plate 17. As shown in FIGS. 1 and 2, a slit 20 communicating with a lower end surface 12a of the tube post 12 is formed near the lower end of the tube post 12 along the longitudinal direction. The slit 20 is used to insert the upright plate 17.
And the thickness is substantially the same. At the intersection of the slit 20 and the lower end surface 12 a of the tube post 12, a notched surface 21 which is cut obliquely for guiding the standing plate 17 is formed. Near the lower end of the column 12, a side portion of the column 12 and a slit 20 are provided.
And the upright plate 17 is slit 20
A fixing pin insertion hole 23 that matches the second through hole 18 in a state where it is inserted into the second through hole 18 is formed. Lower end surface 12 of tube post 12
a is formed with four concave portions 26 for accommodating four nuts 25 screwed to the screw bolts 15 described later. Next, a joining structure performed by using the members configured as described above will be described with reference to FIGS. Connect the beam 11 to the male thread 1 of the screw bolt 15
The surface from which 2b protrudes is arranged as the upper surface side. The portion where the male screw portion 12b protrudes is the connection position of the tube column 12.
The T-shaped bracket 13 is lowered so that the male screw portions 12b of the screw bolts 15 are inserted into the four first through holes 18 formed in the substrate 16 of the T-shaped bracket 13. The board 16 is accurately placed along the beam 11 in the inserted state,
It does not protrude laterally beyond the thickness of. Then, a nut 25 is attached to each male screw portion 12b, and the T-shaped bracket 13 is tightened by the nut 25 and fixed to the beam 11. Next, the tube post 12 is lowered from above the T-shaped bracket 13, and the standing plate 17 of the T-shaped bracket 13 is inserted into the slit 20 of the tube column 12. At this time, the lower end surface 1 of the tube post 12
The lower end surface 12a of the tube post 12 is brought into contact with the upper surface of the substrate 16 of the T-shaped bracket 13 while making fine adjustment so that the nut 25 is accommodated in the concave portion 26 of 2a. In this state, the second through hole 18 and the fixing pin insertion hole 23 coincide. Then, the fixing pin 2 is inserted through the external opening 23a of the fixing pin insertion hole 23 on the side of the tube post 12.

a is formed. The fixing pin 28 is inserted into the second through hole 18 of the upright plate 17 at the tip end thereof, and the bulging portion 28a is forcibly fitted between the fixing pin 28 and the wall surface of the fixing pin insertion hole 23 to prevent falling off. Is done. As described above, the configuration as in the present embodiment has the following effects. -Screw bolt 1 on beam 11 before factory shipment
If the pipe 5 is buried, the T-shaped bracket 13 is connected to the male screw portion 1 of each screw bolt 15 when the pipe column 12 is joined at the construction site.
Positioning can be performed only by placing the 2b and the through hole 18 in correspondence with each other, and accurate positioning can be performed more accurately than conventional positioning means which is completed only when the T-shaped bracket 13 is fixed with a screw bolt. This is extremely effective in shortening the construction period. -The work of fixing the T-shaped bracket 13 with the screw bolts required skill and time. In the above embodiment, the nut 25 is merely tightened at the site, and the positioning of the T-shaped bracket 13 has already been completed, so that the T-shaped bracket 13 can be fixed very quickly. The position of the tube column 12 is uniquely determined by fine adjustment so that the nut 25 is housed in the concave portion 26, and the second through hole 1 is determined.
8 and the fixing pin insertion hole 23 automatically coincide with each other, and the nut 25, which should be a hindrance, turns around, contributing to an increase in work efficiency. Since a notched surface 21 which is notched obliquely is formed at the intersection of the slit 20 and the lower end surface 12a of the pipe post 12, the pipe post 12 is lowered and the T-shaped fitting 13 is inserted into the slit 20 of the post 12. When the standing plate 17 is inserted, the notch 21
Serves as a guide for the standing plate 17 and contributes to the efficiency of work. The above embodiment can be modified as follows. In the above embodiment, the beam 11 and the tube column 12 are used as an example. However, the present invention can be applied to all other situations where the edge of the second structural material is brought into contact with the side of the first structural material. It is possible. Further, a material other than the laminated wood may be used. The T-shaped fitting 13 described in the above embodiment is an example, and any shape of connecting fitting other than the T-shaped fitting 13 may be used as long as it is a connecting fitting for the purpose of the present invention. In the above embodiment, the screw bolt 15 is embedded. However, the present invention is not limited to the screw bolt 15 as long as the side male screw portion of the first structural member projects before the construction is performed on site. The means for fixing the T-shaped bracket 13 to the pipe 12 may be any means other than the fixing pin 28 in the above embodiment. In addition, the present invention can be freely modified and implemented without departing from the spirit thereof. [0014]
