And insertion holes 8 and 9 that are located in the middle in the longitudinal (depth) direction of the mortises 6 and 7.
[0010]
In addition, in the case of the mortise on the existing foundation or horizontal member side, there is also a means to form a mortise by projecting from the existing column main body and extracting the tenon material separated from the column main body from the mortise hole In this case, the mortise usually has a square cross section, and a mortise material having a diameter corresponding to the mortise is used.
[0011]
The pillar 3 interposed between the base 1 and the horizontal member 2 has an engagement hole at the center portion that coincides with the mortises 6 and 7 of the base 1 or the horizontal member 2 on both end faces 3 ′ and 3 ″. 10 and 11 are provided, and the tenon members 4 and 5 are accommodated in the engagement holes 10 and 11, respectively.
[0012]
The tenon members 4 and 5 may be cylindrical bodies (square tube bodies. When a square tube body is used, the mortise hole should have a square shape that matches the cross-sectional shape of the square tube body or a circular shape with a larger diameter than that. And provided in the base 1 or the horizontal member 2 when fitted into the mortises 6 and 7 of the base 1 or the horizontal member 2 on the tip side which is the half 4a, 5a side. Through holes 12 and 13 are provided at positions corresponding to the fitting insertion holes 8 and 9, and through holes 14 and 15 are also provided on the other half 4b and 5b side of the base end side. The tenon members 4a and 5a are placed at positions corresponding to the fitting insertion holes 16 and 17 provided on the end portion side of the column 3 when the half halves 4a and 5a are inserted into the tenon holes 6 and 7, as described above. , 5 are provided in the other half of the base end side.
[0013]
Moreover, the lower tenon material 5 accommodated in the base end part (lower end part) of the upper tenon material 4 accommodated in the engagement hole 10 on the upper end part side of the column 3 and the engagement hole 11 on the lower end part side of the column 3. In each of the front end portions (lower end portions), through holes 18, 19 are provided in a direction perpendicular to the axial direction of the through holes 12, 13, 14, 15 to the insertion holes 8, 9, 16, 17. Both ends of the operation cords 20 and 21 passed through the through holes 18 and 19 are led out from the mortises 6 and 7, and the end faces 3 ′ and 3 ″ of the column 3 are parallel to the through holes 18 and 19. In this embodiment, the guide 3 is led out to the outside of the column 3 through the guide grooves 22 and 23, and both ends thereof are fixed to the column 3 by fixing means 24 and 24 '.
[0014]
In order to obtain this embodiment, the tenon members 4 and 5 in a state where the operation strings 20 and 21 are combined with the engagement holes 10 and 11 provided in the column 3 through the through holes 18 and 19 are formed on the upper tenon member 4. Then, from the base end side where the operation cord 20 is assembled, the lower tenon material 5 is inserted and accommodated from the distal end side where the operation cord 21 is not assembled. 11 are fixed to the pillar 3 by fixing means 24, 24 ', and the lid rod 25 made of an elastic material is used in the lower guide groove 23 by utilizing its elasticity. Forcibly fitting and the cover rod 25 (not necessarily required) reliably prevents the lower tenon material 5 from coming off from the engagement hole 11 due to its own weight, so that the base 1 and the horizontal member 2 side The column 3 is interposed between the base 1 and the horizontal member 2 so that the engagement holes 10 and 11 are aligned with the mortises 6 and 7. It was obtained.
[0015]
Then, when one fastening means 24 is removed and the end of the operation cord 20 on the removed fastening means 24 side is pulled, the length of the portion of the cord 20 existing in the engagement hole 10 is shortened as a whole. The tenon 4 rises with the movement of the operating string 20, and a half of the tip side is inserted into the tenon 6 on the side of the horizontal member 2 at the position coincident with the upper engagement hole 10, and the tenon The through-holes 12 and 13 provided in 4 rise to a position where the horizontal insertion member 2 and the fitting insertion holes 8 and 16 provided in the upper end of the column 3 coincide with each other. When the connecting rod 26 is inserted into the insertion holes 8 and 16 through the through holes 12 and 14, the column 3 and the horizontal member 2 are joined.
[0016]
Further, when the lid 25 is removed from the guide groove 23, one fastening means 24 is removed in the same manner as the operation on the upper side of the pillar 3, and the operation string 20 on the removed fastening means 24 side is loosened. The lower tenon material 5 whose protrusion from the engagement hole 11 is regulated by the string 20 protrudes from the engagement hole 11 by its own weight, descends and is inserted into the tenon hole 7 on the base 1 side, and penetrates on the tenon material 5 side. The holes 15 and 13 coincide with the insertion holes 17 and 9 on the pillar 3 or the base 1 side, and in this state, the connecting rods 26 are inserted into the fitting insertion holes 13 on the base 1 and the pillar 3 lower side through the through holes 9, respectively. By doing so, the lower part of the pillar 3 and the base 1 are joined.
[0017]
The tenon members 4 and 5 of the second embodiment shown in FIG. 7 are provided with notches 18A and 19A in place of the through holes 18 and 19.
[0018]
【The invention's effect】
Since the present invention has the configuration as described above, a tenon member is interposed between a cross member such as an existing horizontal member, and the tenon member is partially inserted into the cross member. The column and the cross member can be securely joined by fixing the cross member to the cross member and the column with a connecting rod. In addition, tenon material is assembled on the pillar side, and this is projected to form a tenon so that the pillar and the cross member are joined together.
