In this joining structure, the joining bolt 51 has a male screw formed over the entire length, and the lower end portion is twisted with the female screw of the bolt hole 31a formed in the plate-shaped main body portion 31 of the base plate 3. The upper part is inserted into the hole 1a formed in the pillar 1. The gap between the inner peripheral surface of the hole 1a and the outer peripheral surface of the joining bolt 51 is filled with an adhesive and cured to bond the column 1 and the joining bolt 51. For example, an epoxy resin can be used as the adhesive.

FIG. 6 shows a front view, a cross-sectional view, and an end view of the joining bolt 51 used in the member joining structure shown in FIG.
The joining bolt 51 is formed with male threads over the entire length of the outer peripheral surface. Then, a central hole 51a is formed which penetrates from one end face to the other end face along the central axis. The central hole 51a serves as an injection hole when the adhesive is injected into the hole 1a formed in the pillar 1. In addition to the opening on the end surface, a plurality of openings 51b extending from the center hole 51a to the outer peripheral surface are formed at the end portion on the tip side when the joining bolt 51 is inserted into the hole 1a formed in the pillar 1. These serve as discharge ports when the hole 1a formed in the pillar 1 is filled with the adhesive.

A tool locking groove 51c in the radial direction is formed on the rear end surface, and when the joining bolt 51 is screwed into a bolt hole provided in the base plate 3, the tool is locked to apply a rotational force. Can be done. Further, on the outer peripheral surface near the rear end, a groove 51d in the axial direction is formed from the rear end surface to a position beyond the range twisted into the bolt hole of the base plate 3. Therefore, as shown in FIG. 5, in a state where the groove 51d is screwed into the bolt hole 31a provided in the plate-shaped main body portion 31 of the base plate 3, the groove 51d is formed in the hole 1a formed in the pillar 1 and the plate-shaped main body portion is formed.

Can be in the formed state.

When the joining bolt 51 is screwed in, the adhesive is injected into the center hole 51a opened in the rear end surface of the joining bolt 51 as shown in FIG. 9A. The adhesive is discharged into the hole 1a formed in the pillar from the discharge port 51b provided near the tip of the joining bolt through the central hole 51a, and is discharged from the outer peripheral surface of the joining bolt 51 and the inner circumference of the hole 1a formed in the pillar. Filled between the faces. When the adhesive is filled in almost the entire area in the hole 1a, it flows into the axial groove 51d formed in the joining bolt 51 as shown in FIG. 9B, and passes through the groove 51d to form the plate-shaped main body. It flows out to the back side of 31. The operator can visually observe this and can confirm that the adhesive is sufficiently filled in the hole 1a. After confirming that the adhesive has been filled, the closing member 53 is attached to the rear end of the joining bolt 51 as shown in FIG. 9C to close the central hole 51a which is the injection port of the adhesive. By curing the adhesive in this state, the base plate 3 can be joined to the pillar 1 via the joining bolt 51.

In the above joining method, a bolt having a male screw formed over the entire length is used, but a bolt having a male screw formed only in the vicinity of the rear end twisted into the bolt hole 31a of the base plate 3 can also be used. .. When such a joining bolt is used, the outer diameter of the tip side is made smaller than the range in which the male screw is formed, and the bolt can be inserted into the bolt hole without being rotated.

Further, in the above joining method, the groove 51d is formed in the portion of the joining bolt 51 twisted to the base plate 3, but the joining bolt is not provided with the groove, and the base plate has a plate shape as shown in FIG. 10A. A groove 31b in the axial direction may be formed on the inner peripheral surface of the bolt hole 31a formed in the main body portion 31.

Similar to the joint bolt 51 shown in FIG. 6, the joint bolt 61 has a male screw formed over the entire length of the outer peripheral surface, and a central hole 61a penetrating from one end surface to the other end surface along the central axis is formed. .. Further, an opening 61b serving as an adhesive discharge port is provided at the end on the tip side, and a tool locking groove 61c for locking a tool for rotating is formed at the end on the rear side.
The axial groove 61d formed on the outer peripheral surface extends to a region twisted with the intermediate member 62 when fixed to the pillar 5 and a predetermined range on both sides thereof. That is, it is a range expanded from the twisted portion to both sides along the axial direction, and in a state of being twisted to the intermediate member 62, a continuous passage from the hole 5a formed in the pillar to the back surface side of the intermediate member 62 is provided. It is what forms.

FIG. 13 shows a front view, a cross-sectional view, and an end view of the intermediate member 62.
As shown in FIG. 11, the intermediate member 62 is fixed by fitting the hole 5a provided in the pillar 5 into a portion where the diameter is expanded near the bottom surface. A female screw that can be twisted with the joint bolt 61 is formed in the central hole of the intermediate member 62, and a spiral overhanging portion 62a having a pitch larger than that of the inner female screw is formed on the outer peripheral surface. As a result, a spiral groove is formed on the inner peripheral surface of the enlarged diameter portion of the hole 5a provided in the pillar 5, and can be screwed in and fixed. A tool locking groove 62b for locking the tool when screwed into the enlarged diameter portion of the hole formed in the pillar 5 is formed on one end surface of the intermediate member 62.
The intermediate member 62 may be fitted into the enlarged diameter portion of the hole formed in the pillar 5 and fixed by an adhesive without providing a spiral overhanging portion on the outer peripheral surface.

FIG. 14 is a plan view and a cross-sectional view showing a state in which the joint bolt 61 is screwed into the intermediate member 62 to a predetermined position. As shown in this figure, the axial groove 61d formed on the outer peripheral surface of the joining bolt 61 forms a continuous passage extending on both sides of the intermediate member 62.

Next, another embodiment of the present invention will be described with respect to a method of joining the base plate 6 to the pillar 5 made of wood by using the joining bolt 61 and the intermediate member 62.
First, a hole 5a is formed at a position where the joint bolt 61 on the end surface of the pillar 5 is embedded, as shown in FIG. 15A. The inner diameter of the hole 5a is expanded near the end surface of the pillar 5, and a spiral groove 5b for screwing the intermediate member 62 is formed on the inner peripheral surface of the expanded portion. Then, as shown in FIG. 15B, the overhanging portion 62a on the outer peripheral surface of the intermediate member 62 is fitted into the spiral groove 5b in the hole 5a, and the intermediate member 62 is screwed into the enlarged diameter portion of the hole 5a. As shown in FIG. 15C, the joining bolt 61 is screwed into the central hole of the intermediate member 62 fixed to the pillar 5 and inserted through the hole 5a formed in the pillar 5 to a predetermined depth. In this example, as shown in FIG. 16A, the rear end portion is in a state of protruding rearward of the intermediate member 62 with the joining bolt 61 inserted to a predetermined depth. With the joining bolt 61 inserted in this way, the joining bolt 61 is supported by the intermediate member 62 fixed to the pillar 5, and is not in contact with the inner peripheral surface of the hole 5a formed in the pillar 5 up to the tip, and is in the periphery. It is possible to make a state in which almost uniform gaps are formed. In this state, the adhesive is injected into the center hole 61a from the rear end surface of the joint bolt 61, and is discharged from the discharge port 61b provided at the tip of the joint bolt 61. Fill the adhesive from the back side.

When the adhesive is filled in almost the entire area between the outer peripheral surface of the joint bolt 61 and the inner peripheral surface of the hole 5a formed in the pillar, the axis line formed in the joint bolt 61 is formed as shown in FIG. 16 (b). It flows into the groove 61d in the direction, and flows out to the back surface side of the intermediate member 62 through the groove 61d. The operator can visually observe this and can confirm that the adhesive is sufficiently filled in the hole 5a. After confirming that the adhesive has been filled, the closing member 64 is attached to the rear end of the joining bolt 61 to close the central hole 61a which is the injection port of the adhesive.
When the joint bolt 61 is fixed, the rear portion of the protruding joint bolt 61 is inserted into the through hole 6a formed in the base plate 6 as shown in FIG. 16 (c), and the base plate 6 is brought into contact with the end surface of the pillar 5. Then, the nut 63 can be twisted to the joining bolt 61 and tightened to the base plate 6 to fix the base plate 6 to the pillar 5.

Although the joining method also uses a joining bolt 61 in which a male screw is formed over the entire length, it is also possible to use a bolt in which a male screw is formed only in a portion twisted to the intermediate member 62.

Further, also in the above-mentioned joining method, the joining bolt 61 has a groove 61d formed in a portion twisted to the intermediate member 62, but the joining bolt is not provided with the groove 61, and the intermediate member is as shown in FIG. 17A. A groove 62c in the axial direction may be formed on the inner peripheral surface of the 62.
