  Embodiments of the present invention will be described with reference to the drawings. 1 (a), (b), FIG. 2 and FIG. 3 show an embodiment of the present invention. A composite member 1 is made of wood on the front and back surfaces of a plate-like steel member 2 such as a single strip steel plate. The bolts 7 are arranged so as to overlap, the shear members 5 are arranged in the through holes 4 of the wooden members 3, the pressing members 6 are arranged outside the wooden members 3, and the fastening bolts 7 are inserted through these members. Each steel member 2, the shear member 5, and the presser member 6 are integrated by tightening and fixing.

  A plurality of shear members 5 are crimped to the front and back surfaces of the plate-shaped steel member 2, and the shear member 5 and the steel member 2 are frictionally joined by the tightening force of the fastening bolt 7. A fastening bolt 7 is inserted through the presser member 6 and the shear member 5, and the plate-like steel member 2 and the wooden member 3 are integrated by the fastening bolt 7 to form a composite member. Each of the wooden members 3 increases the rigidity in the out-of-plane direction (weak axis direction) of the plate-shaped steel member 2, and transmits the shearing force to the wooden member 3 via the shear member 5. In the embodiment shown in FIGS. 1 to 3, the plate-like steel member 2 is projected from both ends of the wooden member 3 to form the joint portion 13, but the both ends of the steel member 2 and the wooden member 3 are aligned. Anyway.

  The outer diameter D of the pressing member 6 is larger than the outer diameter d of the shear member 5, and the pressing member 6 prevents the wooden member 3 from coming off. Since the state where the inner side of the pressing member 6 is in contact with the outer surface of the wooden member 3 is preferable, the plate thickness dimension of the wooden member 3 and the axial length dimension L of the shear member 5 are made substantially the same. When the length dimension of the shear member 5 is shorter than the thickness of the wooden member 3, the presser member 6 is pressed so that the wooden member 3 is pressed. Is not preferable because it weakens.

  The through hole 4 of the wooden member 3 in the form shown in FIG. 1 has a cross section in which the hole in the portion where the shear member 5 is disposed has the same inner diameter over the entire length in the hole axial direction because the shear member 5 is disposed over the entire length in the axial direction. It is a hollow columnar through-hole with a circular hole. In this way, by forming the simple hollow columnar through-hole 4 having the same inner diameter over the entire length in the hole axial direction, the processing of the through-hole 4 on the wooden member 3 side is facilitated, and the size of the through-hole 4 is controlled. Making it easy.

  Further, a steel shear member having an outer diameter that is the same as or slightly larger than the inner diameter of the circular hole in the cross-section and the same outer diameter in the axial direction is struck into the through-hole 4 having the same inner diameter over the entire length. By contact or press-fitting. By thus press-fitting and arranging the shear member 5, the backlash between the shear member and the wooden member 3 can be reliably prevented.

  The bolt insertion holes 8 provided at intervals in the longitudinal direction of the steel member 2 have a larger diameter than the bolt insertion holes 9 of the shear member 5 so that dimensional errors of the respective members can be absorbed. The outer diameter D of the steel member 2 is larger than the bolt insertion hole 8, and the inner diameter of the bolt insertion hole 9 of the shear member 5 is smaller than the bolt insertion hole 8 of the steel member 2. When the shear member 5 is tightened with the fastening bolt 7, the frictional joining surface with the steel member 2 is secured.

  The head 10 of the fastening bolt 7 is arranged on the holding member 6 outside the outer end surface of one shear member 5, and the nut 11 is arranged on the holding member 6 outside the outer end surface of the other shear member 5. Therefore, since the fastening force (compression force) by the fastening bolt 7 and the nut is acting over the entire length of the shear member 5, when the load is applied to the composite member 1, a shearing force is applied to the wooden member 3. In the case of transmission, the composite member 1 can transmit the shear stress to the wooden member 3 almost uniformly and efficiently over the entire length of the shear member 5.

  After the shear member 5 is press-fitted and arranged in the through hole 4 in the wooden member 3, each wooden member 3 may be superposed on the steel member 2, and the composite member 1 may be assembled by the holding member 6 and the fastening bolt 7, After superposing the wooden member 3 on the steel member 2, the shear member 5 may be abutted or press-fitted. As the fastening bolt 7, a high-strength bolt or the like can be used. In this way, the structure in which the fastening bolts 7 and the shear members 5 are arranged at equal intervals over the entire length of the composite member 1 ensures that the shear member 5 and the wooden member 3 are sheared over the longitudinal direction of the composite member 1. 5 and the fastening bolt 7 can surely be integrated to prevent slippage.

  As shown in FIGS. 2 and 3, when the shear member 5 is solid with the fastening bolt insertion hole 7 formed, a strong shear member 5 can be manufactured, and the fastening bolt 7 is inserted and positioned in a thin cylindrical shape. It may be easier and more reliable than in some cases, and although not shown in the drawings, when the intermediate part of the shear member 5 has a circular cross section and a thin cylindrical shape, the outer surface of one end face plate in the axial direction is used as a friction joining surface.

  Then, the joining structure (henceforth a joining structure) of the wooden member and steel plate in this embodiment is demonstrated. FIG. 12 is a longitudinal front view of the joint structure, showing a first example of the joint structure of the wooden member and the steel plate in the present embodiment. In the following embodiments, the principle of friction joining by the fastening bolt 7, the mechanism of various stress transmissions, the dimensional characteristics and the relations of the members, etc. already described in the above embodiment are the same, and detailed description thereof is omitted. In the drawings, the same reference numerals are used to indicate the same members and the like.

  As an example, the joining structure 100 according to the present embodiment assumes a situation in which a steel plate 101 such as a gusset plate that is necessary for connection with another member is joined at the end of the wooden member 3. Of course, the present invention is not limited to such an application example, and can be applied to various situations in which the wooden member 3 and the steel plate 101 are joined.

Under such circumstances, a cylindrical shear member 5 having an outer diameter equal to or larger than the inner diameter of the through hole 4 over the entire length in the axial direction and provided with an insertion hole 9 for the fastening bolt 7 in the inner space. Is inserted into each through-hole 9 of the wooden member 3 arranged in opposition. Thus, the shear member 5 is placed in contact with the steel plate 101. Further, the fastening bolts 7 are inserted into the insertion holes 9 of the fastening bolts 7 and the through-holes 8 of the steel plate 101 in the shear members 5 through the pressing members 6 arranged on the surfaces of the wooden members 3 arranged to face each other. Communicate. And the bolt fastening of the said fastening bolt 7 is performed, and each shear member 5 is crimped | bonded to the said steel plate 101, and it friction-joins. By establishing this friction joining, the joining of the wooden member 3 and the steel plate 101 can be ensured without deviation.

  In other words, the structure in which the fastening bolt 7 is inserted and arranged in the shear member 5 can provide a structure in which the shear member 5 is frictionally joined to the steel plate 101, and the wooden member 3 and the steel plate 101 are integrated to prevent misalignment. Can be a promoted structure. Therefore, the wooden member 3 is prevented from being displaced with respect to the steel plate 101 and integrated, and the wooden member 3 can contribute to a buckling restraint function and some stress load, and a highly durable construction structure can be obtained. is there.

  Moreover, not only can the outer shape of the shear member 5 be simplified to a simple cylindrical shape without a tapered outer peripheral surface, but also the cross-sectional shape of the through hole 4 of the wooden member 3 can be a simple circle. In addition, since it has a simple shape with an inner diameter that is the same as or slightly smaller than the outer diameter of the shear member 5, it is easy to manage the outer diameter of the shear member 5 and the size of the through hole 4 of the wooden member 3. is there. In addition, the backlash between the shear member 5 and the wooden member 3 can be prevented, and the shear member 5 can also be easily disposed by hitting the insertion hole 9 of the wooden member 3 or the shear member 5 or the like.

  As another embodiment of the bonding structure 100, there is a structure shown in FIG. FIG. 13 is a longitudinal front view of a joint structure showing a second example of the joint structure of a wooden member and a steel plate in the present embodiment. This structural example is based on the premise that slits 102 having at least the same width as the distance 103 between the opposed wooden members 3 are provided at the ends of the wooden members 3. And the said steel plate 101 is arrange | positioned to the said slit 102, and the joining of the said wooden member 3 and the steel plate 101 is performed similarly to the above using the said shear member 5, the fastening bolt 7, and the pressing member 6 grade | etc.,. As a result, the structure of the present invention can be introduced not only in the case of a pair of wooden members 3 but also in a simple process of slit formation for a single wooden member. Therefore, there is an effect that reliable friction joining can be ensured simply and reliably.

  FIG. 14 is a longitudinal front view of a joint structure showing a third example of the joint structure of a wooden member and a steel plate in the present embodiment. Further, an example of a joining structure different from the above will be described. In this joining structure 100, as shown in FIG. 14, the through hole 4 disposed on the surface of the wooden member 3 is formed by a large diameter hole 4a having a large inner diameter and a small diameter hole 4b connected to the inside thereof. Shaped through-holes.

  In such a form of the through-hole 4, the shear member 5 is disposed in the small-diameter hole 4b, and the pressing member 6 is brought close to or engaged with the support step portion on the axially outer side of the small-diameter hole 4b. Thereafter, similarly to the above, the wooden member 3 and the steel plate 101 are joined using the shear member 5, the fastening bolt 7, the pressing member 6, and the like. If such a joining structure 100 is adopted, the head of the fastening bolt 7 or the nut 10 is disposed so as to be accommodated in the large-diameter hole 4a, and the head of the fastening bolt 7 or the nut 10 is placed outside the wooden member 3. Can be stored and arranged. Therefore, a structure with a reduced dead space can be obtained as compared with the case where the fastening bolt 7 or the nut 10 protrudes.

  Moreover, the length dimension of the through-hole 4 of the wooden member 3 or the shear member 5 in the hole axial direction can be made short and small, the shear member 5 is disposed in the small-diameter hole 4b, and the presser member 6 is connected to the through-hole 4. By the structure which adjoins or engages with the support step part of the axial direction outer side of this, the structure which aimed at the detachment | leave prevention of the wooden member 3 can be obtained, accommodating the pressing member 6 in the wooden member 3.

  FIG. 15 is a longitudinal front view of a joint structure showing a fourth example of the joint structure between a wooden member and a steel plate in the present embodiment. Further, another example of the joining structure 100 will be described. In this joining structure 100, as shown in FIG. 15, the pressing member 6 includes a washer portion 6a that is close to or engages with the support step portion and a cylindrical portion 6b that is integral therewith. In addition, the cylindrical portion 6b is disposed on the large-diameter hole 4a side, and a lid member 15 is provided at the opening of the cylindrical portion 6b.

  Thereby, the head of the fastening bolt 7 and the nut 10 can be accommodated in the holding member 6 arranged on the large-diameter hole 4a side of the wooden member 3, and the fastening bolt 7 and the nut 10 on the outer surface side of the wooden member 3 can be accommodated. The nut 10 does not protrude and can be hidden by the cover member 15 so as not to be exposed. Therefore, an aesthetically superior structure can be obtained. Moreover, when the cylindrical part 6b is contact | abutting to the large diameter hole 4a inner peripheral surface, the said cylindrical part 6b becomes a structure which can transmit a shearing force to the wooden member 3, and is more suitable.

  FIG. 16 is a longitudinal front view of the joint structure, showing a fifth example of the joint structure between the wooden member and the steel plate in the present embodiment. Next, unlike the above-described joining structure 100 using only the shear member 5, an example using the sheath 60 will be described below. In this structure 100, as shown in FIG. 16, the fastening bolt 7 is interposed between the shear member 5 inserted into the through hole 4 and the presser member 6 disposed on the surface of the wooden member 3. The sheath 60 having the insertion hole 62 in the inner space is arranged. Even when the thickness of the wooden member 3 is large, a sheath pipe hole 61 may be provided in addition to the through hole 4 (it may be continuous with the same diameter as the through hole 4), and the sheath pipe is provided here. By arranging 60, the size of the shear member 5 that tends to be relatively heavy can be used with a constant size. Accordingly, the sheath 60 can be disposed in accordance with the thickness of the wooden member 3 to ensure the frictional joining.

  Note that the bonding structure 100 as described above can be employed in various structures. FIG. 17 is a bird's-eye view showing (a) structure example 1 and (b) structure example 2 to which a joining structure of a wooden member and a steel plate in the present embodiment is applied.

The high-strength bolts are connected to each other.

  Moreover, the structure 200 shown in FIG.17 (b) assumes the single layer dome comprised combining the wooden member 3, for example. In such a situation, high-strength bolts are connected after the steel plates 204 of the joining block 202 and the steel plates 205 of the wooden member 3 are overlapped at the nodes of the wooden member 3 constituting the single-layer dome. .

  In any case, the shear member 5 can be easily placed by hitting the wooden member 3 or the through hole 9 of the shear member 5 to fix the shear member 5 and the steel plate 101 in a frictional manner, thereby completely eliminating the play. A structure that can be obtained can be obtained simply and quickly, and conversely, the shear member 5 and the steel plate 101 can be easily and quickly removed by easily removing the shear member 5 from the wooden member 3 or the through hole 9 of the shear member 5. It is possible to dismantle. Therefore, it is possible to easily and efficiently construct a joint structure between the wooden member 3 and the steel plate 101 and, conversely, disassemble the joint structure. Furthermore, since the wooden member 3 and the steel plate 101 can be easily separated completely with little damage to each other, the wooden member 3 and the steel plate 101 after disassembly can be reused. Therefore, effects such as reduction of member costs and improvement of processing efficiency due to resource reuse and waste reduction can be achieved.
