Description

  The present invention relates to a wooden member joining structure in which a horizontal member such as a beam is joined to a side surface of a main member such as a column or a beam in a wooden frame.

  In the case of wooden shafts, joints and joints have been processed on-site in the past, but due to the disadvantage that the construction period is prolonged, in recent years, precut processing of joints, joints, etc. has been performed at the factory, and these joints have been patented. 1. It joins using the joining metal fitting described in patent document 2.

For example, in the frame structure of a wooden building disclosed in Patent Document 2, the attachment part of the hardware 1 formed by bending a metal plate as a connection structure of a wooden frame that joins columns and beams or beams and beams, etc. 3 is brought into contact with the side surface of the pillar 5 or the like and fixed with a bolt 7, and the pair of insertion support portions 9 and 9 are inserted into a slit 13 formed on the end surface of the beam 11 and fixed with a bolt or a pin 15. It was.

However, since the conventional hardware 1 is U-shaped, it is necessary to perform a fastening operation between the pair of insertion support portions 9 and 9 using a dedicated tool, and workability is poor.
Further, since the support holes 17a, 17b, and 17c are formed in each of the pair of insertion support portions 9 and 9, all the support holes 17a and 17b of the pair of insertion support portions 9 and 9 are caused by twisting of the beam 11 or the like. It was not easy to match 17c, and there was a problem of poor workability. For this reason, for example, the through holes 19, 21a, 21b, and 21c of the column 5 and the beam 11 are made larger, but the shaft assembly accuracy is lowered.

Furthermore, in order to attach the metal object 1 formed in the U-shape to the center of the pillar 5, for example, when inserting in two directions, the position of the bolt 7 interferes. For this reason, since the hardware 1 on both sides was tightened together using a special long bolt, the types of bolts increased, and the parts management became complicated.
Further, since the head or nut of the bolt 7 and the tip of the bolt protrude between the insertion support portions 9 and 9, it is necessary to provide a large recess 23 on the end face of the beam 11 to avoid them. As a result, the cross-sectional defect becomes larger and special pre-cut processing is required.
In addition, a part of the hardware 1 is exposed from the recess 23 and there is a problem that the appearance is lowered.
Further, the recess 23 becomes an opening, and there is a problem in that the metal part is exposed to a flame at the time of a fire and the strength of the hardware is lowered.

The wood member joining structure according to the present embodiment can be suitably used for joining the main member and the horizontal member. Here, the main member refers to a column or a beam. The horizontal member is a beam. Therefore, in the joint structure according to the present embodiment, columns and beams, and beams and beams can be suitably joined.

  In the present embodiment, an L-shaped hardware 35 is used for joining the beam 31 as a main member and the beam 33 as a horizontal member. The L-shaped metal piece 35 has a rectangular board portion 37 that is long in the vertical direction (up and down in FIG. 1), a plurality of fixing holes 39a, 39b, 39c, and 39d arranged in parallel in the longitudinal direction of the board portion 37, and the fixing.

  A notch 47 is formed at the boundary between the upper and lower sides of the support plate portion 43 and the substrate portion 37, and the vertical dimension of the support plate portion 43 in the notch 47 is substantially the same as the vertical size of the substrate portion 37. The support hole 45a is a C-shaped hole that opens at the upper side, and both edges of the opening are tapered guide surfaces 49 that expand outward.

  A concave portion 51 is formed on the side surface 31 a of the beam 31, and the concave portion 51 has a shape into which the substrate portion 37 is fitted. The recess 51 is formed by precut processing. At least two main material through holes 53a, 53b are formed in the bottom surface 51a of the recess 51 in accordance with any of the fixing holes 39a, 39b, 39c, 39d, and the main material through holes 53a, 53b are formed on the other side surface 31b. It penetrates and the inner diameter substantially matches the outer diameter of the cylindrical projections 41, 41. The cylindrical protrusions 41 and 41 may be formed by welding and fixing the pipe material or by extending the substrate portion 37 by pressing. The main material through-holes 53a and 53b include a fitting hole 55 into which the cylindrical protrusions 41 and 41 are fitted, and a counterbore portion 57 into which a head of a fastening member described later is fitted.

  By forming the vertically long recess 51 in the beam 31, thin wall portions 59 are formed at the upper and lower ends of the recess 51. The wall portion 59 is less likely to be cracked because the longitudinal direction of the beam 31 is the wood fiber direction.

Here, the end surface center refers to the center of the end surface through which the central axis of the beam 33 passes. Therefore, the slit 61 is formed at the center of the beam 33 in the width W direction. The slit 61 is formed by precut processing.

  Further, a pin hole 65 into which the pin 63 is driven is formed in the side surface 33a of the beam 33. This pin hole 65 is also drilled by precut processing. The pin hole 65 is disposed at a position corresponding to the support holes 45 a and 45 b of the support plate portion 43 inserted into the slit 61. In the present embodiment, the case where the pin 63 is driven will be described as an example, but a fastening member described later may be inserted into the side surface 33a of the beam 33.

As the fastening member 67, a bolt having a head 67a can be preferably used. The fastening member 67 has a substantially disk shape in which the outer diameter of the head portion 67 a substantially matches the inner diameter of the spot facing portion 57. Further, the outer diameter of the shaft portion substantially matches the inner diameter of the cylindrical protrusions 41, 41. The fastening member 67 is inserted from the other side surface 31 b of the beam 31, and nuts 69 and 69 are screwed to the tips of the board portion 37 that penetrate the cylindrical protrusions 41 and 41.

  As shown in FIG. 2, the fastening member 67 has the nuts 69 and 69 screwed to the tip, and the tip and the nuts 69 and 69 are accommodated in the recess 51 in a state where the substrate portion 37 is fixed to the bottom surface 51 a. It is like that. That is, both ends (head 67a, tip) of the fastening member 67 do not protrude from the side surface 31a of the beam 31 and the other side surface 31b.

  A polygonal hole 71 is formed in the center of the support plate portion 43. The polygonal hole 71 has the same corner 71 a as the outer diameter R of the pin 63. That is, the pin 63 driven from the side surface 33a of the beam 33 is inserted into the polygonal hole 71 so as to be in contact with the inner periphery, particularly the corner 71a. Although the hole into which the pin 63 is inserted is not shown, the position can be specified and drilled in advance by precut processing.

  By providing the polygonal hole 71 in the support plate portion 43, the L-shaped hardware 35 can be easily carried by hooking a finger on the polygonal hole 71, and workability when attaching the L-shaped hardware 35. To improve. Further, since the polygonal hole 71 is provided, the reinforcing pin 63 can be additionally driven in an arbitrary position that abuts on the inner periphery of the polygonal hole 71.

  Here, the polygonal hole 71 is preferably a triangular hole as shown. When the polygonal hole 71 is a triangular hole, when the pin 63 is brought into contact with the corner portion 71a, an R portion capable of coming into contact with the outer peripheral surface of the pin 63 is increased, and the movement of the pin 63 is more effectively restricted. Thus, the fixing strength between the support plate portion 43 and the beam 33 can be further increased. Further, it becomes possible to select any one of the three corners 71a and bring the pin 63 into contact with each other, and it becomes possible to select a pin driving position suitable for a desired stress, that is, a stress applied to the beam 33 or the like. .

  In the wood member joining structure according to the present embodiment, the support plate portion 43 protruding from the beam 31 is thus inserted into the slit 61, and the pin 63 inserted through the side surface 33a of the beam 33 as shown in FIG. Are passed through the support holes 45a and 45b of the support plate portion 43. As a result, the beam 33 is joined to the side surface 31 a of the beam 31 via the L-shaped hardware 35.

Next, the construction procedure of the joining structure of wood members configured as described above will be described.
4 is an explanatory diagram of the construction procedure before inserting the fastening member, FIG. 5 is an exploded perspective view when the main member is a pillar, FIG. 6 is an explanatory diagram of the construction procedure before inserting the beam, and FIG. FIG. 8 is a cross-sectional view when the material is inserted in two directions, FIG. 8 is an explanatory view showing the horizontal cross-section when the horizontal member is inserted in three directions into the main member, and FIG. It is a disassembled perspective view of the junction structure which used the L-shaped metal fitting for the upper and lower two steps.
First, when joining the beam 31 and the beam 33, as shown in FIG. 4, the board | substrate part 37 of the L-shaped metal fitting 35 is inserted in the recessed part 51 formed in the side 31a of the beam 31 which is a main member. At this time, the L-shaped hardware 35 can easily fit the substrate portion 37 into the concave portion 51 by inserting and gripping fingers into the polygonal hole 71. By inserting the substrate portion 37 into the recess 51, the cylindrical protrusions 41 and 41 are simultaneously inserted into the main material through holes 53a and 53b. As a result, the L-shaped hardware 35 is positioned at a predetermined position.

  Next, the fastening member 67 is inserted from the main material through holes 53a and 53b on the other side surface 31b, and the nuts 69 and 69 are screwed to the front ends penetrating the board portion 37. Thereby, the L-shaped hardware 35 is completely fixed to the side surface 31a of the beam 31. In the case where the main member is the column 81, as shown in FIG. 5, the substrate portion 37 of the L-shaped metal piece 35 is fixed to the side surface 81a of the column 81 while being shifted from the center CL. As a result, the support plate portion 43 of the L-shaped hardware 35 is disposed at the center CL of the column 81.

  Next, as shown in FIG. 6, the slit 61 of the beam 33, which is a horizontal member, is inserted into the support plate portion 43 protruding from the beam 31. After the insertion, the pin 63 is driven into the pin hole 65 opened in the side surface 33 a of the beam 33 and penetrates into the support holes 45 a and 45 b of the support plate portion 43. As a result, the beam 33 is joined to the beam 31 via the support plate portion 43 of the L-shaped hardware 35. In addition, since the support hole 45a in the upper part of the support plate part 43 is an open hole, the pin 63 is inserted in the pin hole 65 in the upper part of the beam 33 in advance, and the beam 33 is dropped from the upper part of the support plate part 43. Thus, temporary support with good workability for hooking the pin 63 into the support hole 45a is possible.

  As shown in FIG. 7, when the beams 33 </ b> A and 33 </ b> B are joined to the both surfaces 81 a and 81 b of the column 81 from two directions using the L-shaped hardware 35 and 35, By disposing the support plate portions 43 and 43 at the center CL, the respective substrate portions 37 and 37 are shifted from the center CL to the opposite side. As a result, the fastening members 67 and 67 for fixing the substrate portions 37 and 37 can be fixed without interfering with each other. That is, the L-shaped hardware 35 can be shared.

  Further, by increasing the number of main material through holes 53a, 53b to four, as shown in FIG. 8, for example, in the case of three-way joining the beams 33A, 33B, 33C from the three directions of the column 81 as the main member, The substrate portion 37 of the L-shaped metal fittings 35 and 35 for joining the linear beams 33A and 33B is fixed by the two inner fixing holes 39b and 39c, and the substrate portion 37 of the L-shaped fitting 35 for joining the orthogonal beams 33C is fixed. By fixing with the two outer fixing holes 39a and 39d, interference of the fastening member 67 can be prevented. That is, the fastening member 67 crosses up and down in the column 81.

  Furthermore, when the cross-sectional dimension of the beam 33 is about 120 mm high × 120 mm wide, it can be joined using one L-shaped metal piece 35. However, a beam 33D having a height of twice, such as 240 mm high × 120 mm wide, is formed. When used, as shown in FIG. 9, two L-shaped hardwares 35, 35 are fixed to the column 81 in two upper and lower stages, and by using these two L-shaped hardwares 35 together, a large beam can be used. Even if it exists, it becomes possible to join with high intensity | strength.

  Further, in the case of joining beams (not shown) of the intermediate height, and when using the L-shaped hardware 35, 35 in the upper and lower two stages, when the upper and lower sides of one of the L-shaped hardware 35 protrudes, Using one L-shaped hardware 35, the fixing holes 39a and 39d are fixed by an additional fastening member 67, and the additional pin 63 is passed through the polygonal hole 71. As a result, even a medium beam can be joined with high strength.

  Therefore, according to the wood member joining structure described above, the wood 33 that joins the beam 33 to the side surface 31 a of the beam 31 using the L-shaped hardware 35 including the substrate portion 37, the cylindrical protrusion 41, and the support plate portion 43. In the joining structure of the members, the concave portion 51 is formed on the side surface 31 a of the beam 31, the main material through holes 53 a and 53 b are formed in the bottom surface 51 a of the concave portion 51, the slit 61 is formed in the beam 33, and the substrate is formed by the fastening member 67. Since the portion 37 is fixed in the concave portion 51 and the pin 63 inserted through the side surface 33a of the beam 33 is passed through the support holes 45a and 45b of the support plate portion 43 inserted into the slit 61, two pieces like conventional hardware There is no need to use a dedicated tool to fasten the metal fittings in the gap between the plates, and the substrate portion 37 is fitted into the recess 51 and the nuts 69, 69 on the surface of the substrate portion are tightened, thereby facilitating easy and reliable positioning. L-shaped hardware 3 It can be fixed to the beam 31.

  Moreover, since it is sufficient to insert one support plate portion 43 into the slit 61, the deformation of the wood such as twisting affects the insertability as in the conventional structure in which two plates are inserted into the two slits. The construction work can be facilitated.

  And since the support plate part 43 is arrange | positioned in the center CL of the pillar 81, the board | substrate part 37 will be arrange | positioned and shifted | deviated from the center CL of the pillar 81, for example, and a beam is inserted into the pillar 81 two ways. Even in the case, interference of the fastening member 67 can be prevented, and the L-shaped metal piece 35 and the fastening member 67 having the same shape can be used, so that the parts can be shared.

  Further, by inserting the substrate portion 37 into the recess 51 of the beam 31, the outer periphery of the substrate portion 37 abuts on the inner wall of the recess 51, and the fixing strength of the L-shaped metal member 35 to the beam 31 can be increased.

  Moreover, the fixing strength of the L-shaped metal fitting 35 to the beam 31 can also be increased by inserting the cylindrical protrusion 41 into the main material through holes 53a and 53b.

  Further, since the support plate portion 43 is one piece, it is only necessary to form one slit 61 in the beam 33, the pre-cut work of the beam 33 can be facilitated, and the cross-sectional defect of the beam 33 can be reduced. Can do.

  In addition, since the fastening member 67 is accommodated in the recess 51, it is not necessary to form a notch or the like for avoiding the fastening member 67 on the end face of the beam 33, and this also facilitates the precut operation, The cross-sectional defect of the beam 33 can also be reduced.

  Furthermore, since the notch for avoiding the fastening member 67 is not required, the L-shaped metal fitting 35 is not exposed greatly, the design can be improved, and the L-shaped metal fitting 35 is directly exposed to the flame at the time of fire. The bonding strength of the L-shaped hardware 35 against fire can be increased.
