Description

  The present invention relates to a joining structure for wood members and a joining method for wood members.

  As a joining structure of wood members, for example, a joining structure in which wood is joined to each other by using a bending yield type joining tool such as a bolt and a drift pin is known (for example, see Non-Patent Document 1). In this joining structure, two wood members extending to the other side are overlapped so as to sandwich one wood member extending to one side from both sides, and penetrating members (bending yield type joining) such as bolts and drift pins are overlapped. Tool) penetrates and transmits stress by bearing pressure. In such a joining structure, of the joined wood members, the wood member sandwiched between the wood members sandwiched from both sides and the wood members sandwiched from both sides are caused by shear deformation generated in the longitudinal direction relative to each other. It is recommended that the penetrating member yield before crushing or breaking, and the diameter ratio of the penetrating member is determined.

Hereinafter, the joining structure of the wooden member of the present invention will be described with reference to the drawings.
In this embodiment, the first beam member 10 as the first wooden member and the second beam member 20 as the second wooden member are connected along the longitudinal direction (predetermined direction) of each of the beam members 10 and 20. A description will be given of an example of a bonding structure to be bonded. As shown in FIG. 1, for example, the two beams 10 and 20 joined in the present embodiment have a substantially rectangular cross section, and are formed into a plate shape such as lumber, laminated wood, LVL, or the like. Wooden board members 10a, 10b, 20a, and 20b are laminated and spelled in a laminating direction, that is, in a direction intersecting the longitudinal direction of the beam 1, for example, Panered (registered trademark) screw manufactured by Synex Corporation. The material is penetrated and integrated. The description and illustration of the spelling material for spelling the three plate members 10a, 10b, 20a, and 20b are omitted.

  In the following description, the plate member disposed in the middle of the three plate members 10a and 10b constituting the first beam member (the left side in FIG. 1) is a first inner plate member 10a as a first protruding plate member. And a pair of plate members sandwiching the first inner plate member 10a from both sides is referred to as a first outer plate member 10b as a first superposed plate material. Further, the plate member disposed in the middle of the three plate members 20a and 20b constituting the second beam member (the right side in FIG. 1) is referred to as a second inner plate member 20a as a second superposed plate member. A pair of plate members sandwiching the inner plate member 20a from both sides will be referred to as a second outer plate member 20b as a second projecting plate member. In the present embodiment, the three plate members 10a, 10b, 20a, and 20b constituting the first beam member 10 and the second beam member 20 are all single-plate laminated members (LVL) and have the same thickness. ing.

  Further, in the following description, a beam 1 in which a first beam member 10 and a second beam member 20 are joined is bridged between two pillars 3, 4 erected at a distance from each other. In this state, the vertical direction is the vertical direction, the longitudinal direction of the bridged beam 1 is the longitudinal direction, and the direction intersecting the longitudinal direction of the bridged beam 1 is three plate members 10a. , 10b, 20a, and 20b are indicated as lamination directions.

  As shown in FIGS. 1 and 2, one end of the first beam member 10 in the longitudinal direction is joined to a column (the left column in FIG. 1) 3, and the other end is formed of a first beam member. The inner plate member 10a has a first protruding portion 10c protruding from the pair of first outer plate members 10b at a predetermined length in the longitudinal direction. That is, the first beam member 10 has a first inner plate member 10a having a first protrusion 10c and a first outer plate member 10b superposed on a portion of the first inner plate member 10a other than the first protrusion 10c. And For this reason, the first protrusion 10c of the first beam member 10 is provided with a first concave portion 10d formed at a predetermined length on both sides in an intersecting direction intersecting the longitudinal direction.

  The second beam member 20 has one end in the longitudinal direction joined to a column (the right column in FIG. 1) 4 and the other end formed by a pair of second outer plate members 20b. It has a second protruding portion 20c protruding at a predetermined length in the longitudinal direction from the second inner plate member 20a. That is, the second beam member 20 is overlapped between a pair of second outer plate members 20b having the second protrusions 20c and a portion of the second outer plate member 20b other than the second protrusions 20c. And an inner plate member 20a. For this reason, a second concave portion 20d formed to a predetermined length is provided between the second projecting portions 20c of the pair of second beam members 20 facing each other in the cross direction.

  The first beam member 10 and the second beam member 20 are joined by the drift pin 5 as a penetrating member in a state where the first protrusion 10c of the first beam member 10 is inserted into the recess 20d of the second beam member 20. Is done. The projecting length of the first projecting portion 10c in the longitudinal direction of the first beam member 10 is equal to the projecting length of the second projecting portion 20 in the longitudinal direction of the second beam member 20. Therefore, in a state where the first beam member 10 and the second beam member 20 are joined, the tip of the first protrusion 10c abuts on the second recess 20d, and the tip of the second protrusion 20c contacts the first recess 20c. 10d.

  The first projecting portion 10c of the first beam member 10 is provided with a plurality of first through holes 10e that penetrate in the stacking direction and into which the drift pins 5 are fitted, and the two second projecting portions of the second beam member 20 are provided. 20c is provided with a plurality of second through holes 20e that penetrate in the stacking direction and into which the drift pins 5 are fitted. Each of the first through hole 10e and the second through hole 20e is formed to have the same inner diameter D1 as the outer diameter D2 of the drift pin 5 or slightly smaller than the outer diameter of the drift pin 5. As shown in FIG. 3A, when the first protrusion 10c is inserted into the second recess 20d, the first through-hole 10e provided in the first protrusion 10c and the first protrusion 10c on both sides of the first protrusion 10c. The second protruding portions 20c are disposed so as to communicate with the second through holes 20e provided in the second protruding portions 20c in the laminating direction and penetrate therethrough.

  The drift pin 5 has a first fitting portion 5a fitted into the first through hole 10e and two second fitting portions 5b fitted into the second through hole 20e. The second fitting portion 5b and the first fitting portion 5a provided on both sides of the first fitting portion 5a respectively have a reduced diameter portion having an outer diameter D3 smaller than the outer diameter D2 of the first fitting portion 5a and the second fitting portion 5b. 5c. Here, the outer diameter D2 of the drift pin 5 is, for example, 20 to 30 mm, and the outer diameter D3 of the reduced diameter portion 5c is, for example, 10 to 15 mm.

  When the first protrusion 10c is inserted into the second recess 20d and the first through-hole 10e and the second through-hole 20e communicate with each other, the drift pin 5 is moved into the first and second through-holes 10e and 20e. It is inserted in. The inserted drift pin 5 extends over the entire width of the beam 1 in the stacking direction, and the length L1 of the first fitting portion 5a in the stacking direction substantially matches the thickness t of the first protrusion 10c in the stacking direction. I have. That is, the first fitting portion 5a is fitted into the first through hole 10e over the entire length t in the thickness direction of the first projecting portion 10c. For this reason, the reduced diameter portion 5c connected to the first insertion portion 5a and the second insertion portion 5b connected to the first insertion portion 5a via the reduced diameter portion 5c are located outside the first through hole 10e. Located in the second through hole 20e. That is, the reduced diameter portion 5c is disposed at the boundary between the first projecting portion 10c and the second projecting portion 20c, and the first fitting portion 5a and the second fitting portion 5b are both the first projecting portion 10c and the second fitting portion 5b. It does not straddle the protrusion 20c.

  The length L2 of each second fitting portion 5b in the stacking direction is shorter than the length L1 of the first fitting portion 5a in the stacking direction. For example, the length L2 of each of the second fitting portions 5b in the stacking direction is formed to be half of the length L1 of the first fitting portion 5a in the stacking direction. That is, the length L2 × 2 of the two second fitting portions 5b in the stacking direction is equal to the length L1 of the first fitting portions 5a in the stacking direction. By setting the lengths L1 and L2 of the first fitting portion 5a and the second fitting portion 5b in the stacking direction in this way, the distance between the first projecting portion 10c and the second projecting portion 20c due to an earthquake or the like can be increased. When a relative displacement occurs, a similar bearing force acts on the first beam member 10 and the second beam member 20.

  When the first beam member 10 and the second beam member 20 are relatively displaced by an earthquake or the like, the beam 1 joined by the joining structure of the wooden members of the present embodiment has the first projecting portion 10c and the second projecting portion. A shear force acts on the drift pin 5 penetrating through the pin 20c. At this time, as the first beam member 10 and the second beam member 20 move relative to each other in a direction away from each other, the drift pin 5 moves, as shown in FIG. The boundary portion with the protruding portion 20c, more specifically, the reduced diameter portion 5c disposed at the position of the first protruding portion 10c in the second through hole 20e provided in the second protruding portion 20c is sheared. As a result, the first beam member 10 and the second beam member 20 absorb energy for relative displacement. In the present embodiment, when the assumed first beam member 10 and second beam member 20 are relatively displaced, the reduced diameter portion 5c is connected to the inner peripheral surface 10f of the first through hole 10e and the second through hole. It is set to yield before it sinks into the inner peripheral surface 20f of 20e. Here, the reduced diameter portion 5c corresponds to a yield portion.

  The method of joining the wooden members for joining the first beam member 10 and the second beam member 20 is as follows. First, in a factory or the like, the first beam member 10 having the first protrusion 10c and the first through hole 10e, The second beam member 20 having the two projecting portions 20c and the second through holes 20e is manufactured (beam member manufacturing step).

  Next, the first beam member 10 and the second beam member 20 manufactured at the factory are carried into the construction site, and the first projecting portion 10c of the first beam member 10 is moved to the second beam member 20 as shown in FIG. Of the second beam member 20, and the second protrusion 20c of the second beam member 10 is inserted into the first recess 10d of the first beam member 10, and the first protrusion 10c and the second protrusion 20c are overlapped. Let it. At this time, the first beam member 10 and the second beam member 20 are arranged such that the superimposed first through hole 10e of the first projecting portion 10c and the second through hole 20e of the second projecting portion 20c communicate with each other. (Arrangement step, FIGS. 4 (a) and 4 (b)).

  Next, the drift pin 5 having the reduced diameter portion 5c is driven into the communicating first through hole 10e and the second through hole 20e to penetrate the first and second projecting portions 10c and 20c, The first beam member 10 and the second beam member 20 are joined (penetration step, FIGS. 4B to 4C). At this time, the tip of the drift pin 5 is positioned such that the surface 1a on which the drift pin 5 is driven and the opposite surface 1b are flush with each other, and the first fitting portion 5a extends over the entire length of the first through hole 10e. It is formed so as to span. When the drift pin 5 is driven, a steel plate (not shown) serving as a stopper is applied to the surface 1b opposite to the surface 1a on which the drift pin 5 is driven, and the drift pin 5 is driven. It is possible to place them in position.

  The first beam member 10 and the second beam member 20 are joined to two columns 3, 4 standing upright at both ends, respectively, and the beam 1 is bridged between the columns 3, 4. Here, the first beam member 10 and the second beam member 20 are overlapped with the first projecting portion 10c and the second projecting portion 20c in a state where they are previously joined to the columns 3 and 4, respectively. It may be joined.

  According to the joining structure of the wood members of the present embodiment, when the first beam member 10 and the second beam member 20 relatively move, the drift pin penetrates the first projecting portion 10c and the second projecting portion 20c. 5 absorbs the energy that the first beam member 10 and the second beam member 20 move relative to each other because the reduced diameter portion 5c whose outer diameter D3 is smaller than the first insertion portion 5a and the second insertion portion 5b yields. It is possible.

  When the first beam member 10 and the second beam member 20 relatively move, the reduced diameter portion 5c yields before the reduced diameter portion 5c sinks into the first beam member 10 or the second beam member 20. Therefore, even if the first beam member 10 and the second beam member 20 relatively move, the reduced diameter portion 5c does not enter the first beam member 10 or the second beam member 20. Therefore, it is possible to prevent the first beam member 10 and the second beam member 20 from being damaged by the reduced diameter portion 5c that yields due to the relative movement.

  Further, since the first fitting portion 5a penetrates the first through hole 10e, it moves integrally with the first projecting portion 10c, and the second fitting portion 5b penetrates the second through hole 20e. It moves integrally with the projection 20c. For this reason, when the first beam member 10 and the second beam member 20 relatively move, the reduced diameter portion 5c provided between the first fitting portion 5a and the second fitting portion 5b is more reliably attached. It is possible to surrender.

  The outer diameter D3 of the reduced diameter portion 5c is formed smaller than the outer diameter D2 of the first fitting portion 5a and the second fitting portion 5b. Therefore, a gap S is provided between the reduced diameter portion 5c and the second beam member 20, that is, between the inner peripheral surface 20f of the second through hole 20e and the reduced diameter portion 5c. Therefore, even when the reduced diameter portion 5c of the drift pin 5 yields, the drift pin 5 hardly contacts the inner peripheral surface 10f of the first through hole 10e and the inner peripheral surface 20f of the second through hole 20e. Therefore, when the drift pin 5 yields, damage to the first beam member 10 and the second beam member 20 can be suppressed more reliably. For this reason, the outer diameter D3 of the reduced diameter portion 5c is such that the reduced diameter portion 5c yields when the first beam member 10 and the second beam member 20 are displaced relative to each other due to the anticipated earthquake motion. It is desirable to set the outer diameter D3 so as not to contact the inner peripheral surface 10f of the first through hole 10e and the inner peripheral surface 20f of the second through hole 20e. Furthermore, when the first beam member 10 and the second beam member 20 relatively move, the reduced diameter portion 5c yields before the reduced diameter portion 5c sinks into the first beam member 10 or the second beam member 20. It is desirable to set so that

  Further, since neither the first fitting portion 5a nor the second fitting portion 5b straddles the first beam member 10 and the second beam member 20, the first beam member 10 and the second beam member 20 are relatively opposed to each other. When the drift pin 5 is moved, the reduced diameter portion 5c can be more reliably yielded and the drift pin 5 can be bent.

  Also, since the second outer plate member 20b sandwiches the first inner plate member 10a from both sides, the drift pin 5 has one first fitting portion 5a and two second fitting portions 5b. are doing. Therefore, the length L2 of the portion where the second fitting portion 5b contacting at two locations is in contact is set to half the length L1 of the portion where the first fitting portion 5a contacting at one location is in contact. Thus, when the first beam member 10 and the second beam member 20 relatively move, it is possible to similarly apply the force to the first beam member 10 and the second beam member 20.

  At this time, the length L2 of the portion where the second fitting portion 5b is in contact is not limited to half the length L1 of the portion where the first fitting portion 5a is in contact. For example, by making the length L2 of the portion where the second fitting portion 5b is in contact with shorter than the length L1 of the portion where the first fitting portion 5a is in contact, the first beam member 10 and the second beam portion are made. It is possible to balance the forces acting when the material 20 relatively moves. At this time, when the first fitting portion 5a is set to the same length as the first through hole 10e and the reduced diameter portion 5c is arranged in the second through hole 20e, the inner circumference of the first through hole 10e in the first fitting portion 5a. It is possible to secure a longer length L1 of the portion that comes into contact with the surface 10f.

  Moreover, according to the joining method of the woody member of the present embodiment, the first projecting portion 10c of the first beam member 10 and the second projecting portion 20c of the second beam member 20 are arranged so as to overlap with each other in the cross direction, and the diameter is reduced. The first and second beam members 10 and 20 are prevented from being damaged by the drift pin 5 only by penetrating the drift pin 5 having the portion 5c through the first and second projection portions 10c and 20c. Also, it is possible to join so that the drift pin 5 can be yielded when the first beam member 10 and the second beam member 20 move relative to each other.

  In the above-described embodiment, an example will be described in which the length of the first through hole 10e in the stacking direction, that is, the thickness t of the first protrusion 10c and the length L1 of the first fitting portion 5a in the stacking direction are set to be the same. However, it is not limited to this. For example, the first fitting portion does not protrude longer than the first through-hole, and the reduced diameter portion is disposed so as to straddle the inside of the first through-hole and the inside of the second through-hole. Any configuration may be used as long as the reduced diameter portion yields at the boundary between the first protrusion and the second protrusion when the beam and the second beam are relatively displaced.

  In the said embodiment, although the 1st beam material 10 and the 2nd beam material 20 which laminated | stacked three board members 10a, 10b, 20a, and 20b as a wooden member to join were described as an example, the beam material is Regardless of the form in which a protrusion and a recess are provided at one end of one piece of wood, or a beam material in which two plate members or four or more plate members are laminated, one end is provided at one end. Any joining structure may be used as long as the projecting portion is provided, the other end portion is provided with a concave portion, the projecting portion is inserted into the concave portion, and a penetrating member having a reduced diameter portion is fitted and joined. The combination of the two beams to be joined may be the same wood or a combination of a beam made of one piece of wood and a laminated plate member.

  Further, in the above-described embodiment, the joining structure of the wooden member and the joining method of the wooden member have been described with an example in which the first beam member 10 and the second beam member 20 as the wooden member are joined. It is not limited. For example, as shown in FIG. 1, the pillar 3 and the beam 1 may be joined by the joining structure of the wooden member of the present invention. In this case, for example, as shown in FIG. 5, the end of the beam 1 on the column 3 side is provided with a recess 10 g similar to the above embodiment, and a pair of protrusions 10 h provided on both sides of the recess 10 g are provided.
