Description

  The present invention relates to a method for manufacturing a wooden structure, a wooden structure, a connection method, and a module.

  When a relatively large space is required in a wooden building, a beam member having a large cross section is required. However, it is difficult to dry, transport and stock the beam material with a large cross section.

  Therefore, a laminated material made by reconstructing wood (plate material) having a small cross-sectional dimension with an adhesive or the like is known. In recent years, attempts have been made to use laminated lumber having a large cross-sectional area for beams in public facilities.

  Simply stacking the laminated materials causes a shift when a vertical load is applied, and structurally, only the effect of arranging individual members horizontally can be exhibited. Therefore, a method for increasing the rigidity of the entire laminated wood is known. For example, a slit having a required depth and width is formed along a length direction on a laminated material main body formed by laminating and bonding a sheet or a small square material having a required thickness, width and length, with the fiber directions parallel to each other. In addition, a structural material is known in which a reinforcing plate-like body is fitted into a slit and integrated with a main assembly of laminated materials.

  In addition, when a relatively large space is required in a wooden building, a beam member having a large cross section is required in accordance with the size of the space. However, a beam material having a large cross-section exceeding the standard cross-section is manufactured after receiving an order, and thus requires time until delivery. In addition, the large cross-section beam is long and requires a larger vehicle for transportation.

JP 2008-230032 A

For example, in Patent Document 1, it is difficult to fit the plate-like body unless the positions of the widths of the slits into which the plate-like body is inserted are matched.
By the way, a beam having a large cross section required for a large space is effective in securing performance required to take a large size in the vertical direction seen from the cross section.

  However, simply stacking beam members with a standard cross section causes the beams to slip when a load is applied, and the effect of increasing the vertical direction viewed from the cross section cannot be obtained.

In general, a method of connecting stacked beam members with bolts or screws can be considered. However, linear members such as screws and bolts have a small area that resists slipping, and it is difficult to obtain the effect of increasing the vertical direction viewed from the cross section.
In one aspect, an object of the present invention is to easily create a strong column / beam by bundling a plurality of members.

  In order to achieve the above object, a method for manufacturing a disclosed wooden structure is provided. In this method of manufacturing a wooden structure, a plurality of timbers are fixed by fixing means so that at least a part of the bottoms of the recesses formed in each of the plurality of timbers to be fixed face each other, and the hardness is higher than that of timber An insertion member having high or comparable hardness is inserted into an opening formed by the recesses facing each other.

  In one aspect, a strong column / beam can be easily created by bundling a plurality of members.

<Embodiment>
FIG. 1 is a diagram illustrating a wooden structure according to an embodiment.
The wooden structure 1 of the embodiment can be used, for example, for a pillar or beam of a wooden building.
The wooden structure 1 includes a plurality of square members 2a to 2e to be fixed.

FIG. 2 is a diagram illustrating the structure of the wooden structure of the embodiment.
Through holes 4 for inserting metal bolts (fixing means) 3a and 3b are provided at predetermined positions of the square members 2a to 2e. The bolts 3a and 3b are inserted into the through holes 4, and the square members 2a to 2e are fixed to each other by being tightened by nuts (not shown) provided at the upper part of the square member 2a and the lower part of the square member 2e.

  As for the size (size) of each of the square members 2a to 2e, for example, the width, the thickness, and the length are 105 mm × 105 mm × 3000 mm. The diameter of the bolts 3a and 3b is, for example, 10 mm.

  Further, on the surfaces of the square members 2a to 2e facing each other, that is, the lower surface of the square member 2a, the upper and lower surfaces of the square members 2b to 2d, and the upper surface of the square member 2e, there are recesses (grooves) 5 at least partially facing each other. It is provided at predetermined intervals. Each recess 5 is provided across the width direction of each of the square members 2a to 2e.

  A rectangular parallelepiped insertion member 6 is disposed in an opening formed by the recesses 5 facing each other. The insertion member 6 is disposed in the opening by, for example, press-fitting the square members 2a to 2e into the concave portions 5 facing each other in a state where the square members 2a to 2e are fixed by bolts 3a and 3b. In addition, the length of the depth of the insertion member 6 is the same length as the width | variety of the squares 2a-2e, for example, is 105 mm.

  Examples of the constituent member of the insertion member 6 include one having a hardness higher than that of the square members 2a to 2e such as resin and steel, or one having the same degree of hardness. As an example, (JIS G 3101 (general structural rolling Steel material)).

FIG. 3 is a diagram illustrating the size of the recess and the insertion member.
The length h1 (for example, 25 mm) of the cross section of the insertion member 6 is the same as or slightly larger than the length h2 (for example, 20 mm) that is twice the depth of the recess 5 provided in each of the square members 2a to 2e. Yes. Further, the width h3 (for example, 15 mm) of the cross section of the insertion member 6 is formed to be the same as or slightly larger than the width h4 (for example, 10 mm) of the recess 5. Thereby, when the insertion member 6 is arrange | positioned in the recessed part 5, it can suppress that a space | gap is formed between the recessed part 5 and the insertion member 6. FIG. In this embodiment, the shape of the insertion member 6 is a rectangular parallelepiped. However, in consideration of ease of insertion of the insertion member 6, the shape of the insertion member 6 may be tapered like a wedge. Good.

  According to the wooden structure 1 having such a structure, by disposing the insertion member 6 in the recess 5, the number of surfaces that are perpendicular to and in contact with the fiber direction of the wood is increased. Accordingly, the strength in the direction in which the respective engaging portions of the square members 2a to 2e slide sideways (the ability to stop the degree of sliding) is high.

If it is intended to suppress the side slip of the square members 2a to 2e from the insertion direction of the bolts 3a and 3b, for example, by increasing the number of bolts, a processing accuracy for inserting the bolts is required. Moreover, the area of each bolt is smaller than the area where the insertion member 6 and the recess 5 are engaged. In this case, the depth cannot be used effectively. On the other hand, according to the wooden structure 1, the insertion member 6 is press-fitted. Thereby, the intensity | strength to the direction in which each engaging part of square member 2a-2e slides side can be made high.
Moreover, the intensity | strength of the wooden structure 1 is securable by arrange | positioning the insertion member 6 and volt | bolt 3a, 3b by turns in the longitudinal direction of the wooden structure 1. FIG.
Next, the manufacturing method of the wooden structure 1 is demonstrated using FIG. 1 and FIG.

  [Step 1] First, 2a to 2e are prepared as square members in which at least one concave portion 5 is formed on each facing surface, and through-holes 4 are provided in a direction in which the depth direction of the concave portion 5 is twisted. To do.

  [Step 2] Next, bolts 3a and 3b penetrating through the respective through holes 4 of the square members 2a to 2e in a state where at least a part of the bottoms 5a of the recesses 5 formed in the square members 2a to 2e to be fixed face each other. The square members 2a to 2e are fixed by inserting.

  [Step 3] Openings are formed by the recesses 5 of the square members 2a to 2e facing each other. The insertion member 6 is press-fitted into the opening using a hammer or the like. Since the insertion member 6 is harder than the square members 2 a to 2 e, the insertion member 6 spreads the recess 5 and sinks into the recess 5. In this way, the inserted insertion member 6 is in close contact with the recess 5.

  In this way, by pressing the insertion member 6 into the recess 5, for example, as shown in FIG. 3, the wooden structure 1 can be manufactured even when the bottoms of the recess 5 face each other with a slight shift. Can do. This has the merit of being easier to manufacture than an aggregate material that cannot be combined unless the respective vertical displacements are aligned to some extent when combined. Also, if the cross section of the recess is cut or the clearance is taken to combine the square bars, the strength in the side-sliding direction may be reduced, but in this embodiment, the insertion member 6 is press-fitted. Thereby, the intensity | strength to the direction in which each engaging part of square member 2a-2e slides side can be made high.

  Moreover, after fixing the squares 2a-2e using the volt | bolts 3a and 3b, it was made to insert the insertion member 6 from the direction in which the volt | bolts 3a and 3b are twisted with respect to the insertion direction. For this reason, for example, compared with the case where a certain member is inserted from the same direction as the insertion direction of a bolt, the cross section which exhibits the stress with respect to deviation can be taken large. In other words, the insertion member 6 has a structure in which the insertion member 6 is thin and flat on the surface. For this reason, shear rigidity (hardness of shearing) can be increased.

Temporarily, the wooden structure 1 can be created by superimposing materials having a popular price among timber distribution materials of 105 mm × 105 mm square members (members generally used for pillars). For this reason, for example, when considering a case of preparing a 300 mm × 300 mm pillar, the manufacturing method of the wooden structure of the present embodiment described above is the same at about half the cost compared to the case of preparing a general laminated material. Can be prepared.
In this way, even a size generally called a custom size (for example, a width and thickness exceeding 450 mm) can be easily manufactured.
Further, not only the cross-sectional shape but also the length of the column can be manufactured to an arbitrary length.

FIG. 4 is a diagram illustrating ease of delivery and manufacturing.
FIG. 4A shows a packing state at the time of delivery. When packing, the square bars 20 having a common size are bundled and delivered. In addition, although the recessed part and the through-hole are provided in the square member 20 similarly to the square members 2a-2e, in FIG. 4, description of a recessed part and a through-hole is abbreviate | omitted.
Then, the square member 20 is developed at the construction site, and a column and a beam having a size to be created are manufactured.

  FIG. 4B is a diagram for explaining the development of the square member 20. In FIG.4 (b), the square structure 20a produced | generated by cutting | disconnecting the square 20 from the center part, and the square 20 are combined using a volt | bolt, a nut, and an insertion member, As shown in FIG.4 (c), it is a wooden structure. A product 30 is manufactured.

  In this way, a wooden structure of various sizes can be manufactured using square bars of a certain size (for example, 105 mm × 105 mm × 3000 mm). be able to. In addition, delivery to a construction site and production of a wooden structure are facilitated.

As described above, according to the wooden structure 1, by superimposing the square members 2a to 2e, it is possible to easily realize from a strong small beam / column to a large beam / column. For this reason, it is possible to easily manufacture and construct beams and columns suitable for, for example, general wooden houses and small to medium-sized public buildings.
Moreover, by using the wooden structure 1, it is possible to draw up the structure only with columns and beams, such as a steel frame or RC structure.

  In addition, according to the wooden structure 1, since a large cross section can be obtained simply by bundling the square members 2a to 2e, the goal of expanding the use of timber in public buildings in the timber utilization promotion law that has been transmitted from the country (* country Goal: All low-rise public buildings will be made of wood, and the use of domestic timber can be expected to be 50%).

  In the present embodiment, square bars 2a to 2e are fixed using bolts 3a and 3b and nuts. However, the fixing method of the square members 2a to 2e is not limited to bolts and nuts.

Further, in this embodiment, the square members 2a to 2e are used. However, as the timber that is a constituent material of the wooden structure of the present embodiment, other than that, a longitudinal joint material, a structural laminated material, a structural plywood, an LVL, and the like. (Single plate laminate), OSB, MDF and the like.
Next, an application example of a wooden structure will be described. The wooden structure of the application example shown below is based on the structure of the wooden structure 1 described above.

<First application example>
FIG. 5 is a diagram for explaining the wooden structure of the first application example.
Fig.5 (a) is a figure which shows the wooden structure of the 1st application example, and FIG.5 (b) is an exploded view of the wooden structure 1a of the 1st application example.
The wooden structure 1a of the first application example has a structure like an H-shaped rope whose section is H-shaped. For this reason, cross-sectional efficiency (bending rigidity and bending strength per weight) is excellent.
The wooden structure 1a has square members 2f and 2g corresponding to flanges referred to as H-shaped ropes and square members 2h corresponding to webs referred to as H-shaped ropes.

  A through hole 7 into which the bolts 3c and 3d are inserted is provided at predetermined positions of the square members 2f to 2h. In addition, at least a part of each of the square members 2f to 2h facing each other, that is, a portion facing the square member 2h on the lower surface of the square member 2f, an upper surface and a lower surface of the square member 2h, and a portion of the square member 2g facing the square member 2h are at least partially. Are provided at predetermined intervals.

The square members 2f to 2h are fixed by inserting bolts 3c and 3d, respectively, and an insertion member 9 is press-fitted into the recesses provided in the square members 2f to 2h, respectively. The depth of the insertion member 9 is the same as the width of the square member 2h.
For example, if the width of the ceiling surface is narrow, the skeleton will appear poor, but since a cross-section can be secured by using the wooden structure 1a, a visual effect is also obtained.

<Second application example>
FIG. 6 is a diagram illustrating a finished product of a wooden structure of the second application example, and FIG. 7 is a diagram illustrating a structure of the wooden structure of the second application example. In addition, although the squares 2i-2r shown in FIG. 7 are provided with a recessed part and a through-hole like the squares 2a-2e, in FIG. 7, description of a recessed part and a through-hole is abbreviate | omitted.

  The wooden structure 1b of the second application example is formed by combining eight square members 2i to 2r. An opening 31 is formed in the center of the wooden structure 1b.

  In this wooden structure 1b, three adjacent square members are fixed to each other by four bolts for each plane. For example, the square members 2i, 2j, and 2k are fixed by the bolt 3e. Square members 2k, 2m, and 2n are fixed by bolts 3f. Square members 2n, 2p, and 2q are fixed by bolts 3g. Square members 2q, 2r, and 2i are fixed by bolts 3h.

  On the mutually opposing surfaces of the adjacent square members 2i to 2r, recesses that are at least partially opposed to each other are provided at predetermined intervals. In these recesses, the insertion member 10 is inserted, for example, by press fitting.

In FIG. 7, the arrangement | positioning state of the volt | bolt in the wooden structure 1b and the insertion member 10 is illustrated. By inserting the two insertion members 10 from one side surface of the wooden structure 1b, a total of eight insertion members 10 are arranged on one plane.
As described above, a wooden structure having an arbitrary width and thickness can be easily manufactured by using a combination of square members and an arrangement pattern of bolts and insertion members.
Moreover, since the opening part 31 is formed in the center, another member (for example, LAN cable etc.) can be passed through this opening part 31. FIG.

<Third application example>
FIG. 8 is a diagram showing a finished product of a wooden structure of the third application example, and FIG. 9 is a diagram for explaining the structure of the wooden structure of the third application example.
The wooden structure 1c of the third application example has square members 41a to 41i.
In this wooden structure 1c, three adjacent square members are fixed by screws. For example, square bars 41d, 41i, and 41h are fixed by screws 3i. Square bars 41f, 41i, 41b are fixed by screws 3j.

  The square members 41i and the square members 41b, 41d, 41f, and 41h adjacent to the square members 41i are provided with two concave portions that are at least partially opposed to each other at both ends. In these recesses, the insertion member 11 is inserted, for example, by press fitting. The square members 41b, 41d, 41f, 41h, 41i shown in FIG. 9 are provided with recesses and through holes, but in FIG. 9, the description of the recesses and the through holes is omitted.

  The square members 41a, 41c, 41e, and 41g are bonded to the adjacent square members by applying an adhesive to the surfaces of the adjacent square members. For example, the square member 41a is bonded to the square members 41b and 41h. These square members 41a, 41c, 41e, and 41g are bonded to adjacent square members after the insertion member 11 is inserted into the recess.

By the way, in FIG. 9, the position of the recessed part provided in square members 41b, 41d, 41f, and 41h is the edge part periphery of a square member, and the recessed part is not provided in the center part. This is because, for example, when a vertical load acts on a beam created using the wooden structure 1c and the center portion is bent, shear stress and bending stress are generated. For example, one-surface shearing is applied to a connecting material in which a plurality of square members are bundled, such as a wooden structure 1c. It is known that this one-surface shearing force is greater as it is closer to the end. Accordingly, the reduction in shear strength is suppressed by arranging the concave portions in the square members 41b, 41d, 41f, and 41h in the vicinity of the end portions.
According to this wooden structure 1c, the number of insertion members and bolts can be reduced as compared with the wooden structure 1b.

<Fourth application example>
FIG. 10 is a diagram illustrating a wooden structure of a fourth application example.
The module 50 shown in FIG. 10A includes a base 51, a beam 52, and pillars (wooden structures) 53a and 53b having the same structure. A horizontal member 54 is provided below the beam 52. An opening 55 is formed in a region surrounded by the horizontal member 54, the beam 52, and the pillars 53a and 53b. A plurality of load-bearing walls 56a to 56d having metal braces are provided below the opening 55.

  Each of the load bearing walls 56a to 56d has the horizontal member 54 and the base 51 in common, the two load bearing walls 56b and 56c in the center are one-way bracing, and the two outer load bearing walls 56a and 56d are bracing. It is hanging.

The structures of the pillars 53a and 53b are the same as the wooden structures 1, 1a, 1b and 1c described above. FIG. 10A illustrates the arrangement pattern of the bolts and the insertion members of the pillars 53a and 53b.
FIG.10 (b) is a figure which shows the pillar which cut the cross section by the AA line of Fig.10 (a).
The column 53a has an L shape in plan view.

  Square members 2t and 2v are fixed to the column 53a by using bolts 3k. The square bars 2t and 2u are fixed by using the bolt 3m. And the insertion member 12a is arrange | positioned at the recessed part provided in each of the squares 2t and 2v. An insertion member 12b is disposed in a recess provided in each of the square members 2t and 2u.

FIG. 11 is a diagram illustrating a square member of a wooden structure according to a fourth application example.
In FIG. 11, a square bar 2t is illustrated as an example. The square member 2t is provided with a recess 2t1 on the surface facing the square member 2v. Further, the square bar 2t is provided with a recess 2t2 on the surface facing the square bar 2u.
Thus, in order to avoid interference between the insertion members 12a and 12b, the recesses 2t1 and 2t2 are alternately arranged at a predetermined interval rather than on the same plane.
FIG. 11 shows a through hole 2t3 through which the bolt 3k passes.

  By using such columns 53a and 53b, it is possible to suppress the displacement between the square members 2t, 2u, and 2v at the time of horizontal load. In addition, according to the method for manufacturing a wooden structure of the embodiment, since the L-shaped processing such as the columns 53a and 53b is easy, the overhang of corners is suppressed as compared with the case of using a rectangular parallelepiped or a cubic column. Can do.

<Comparative example>
FIG. 12 is a diagram illustrating a shaft assembly using the wooden structure of the embodiment.
FIG. 12A shows a shaft set using the columns 53a and 53b of the embodiment, and FIG. 12B shows a shaft set (comparative example) when the wooden structure of the embodiment is not used.
The difference between the shaft set 60 and the shaft set 70 is that the reference strength can be secured without providing a bearing wall. As a result, it is possible to perform a more open and free design with a high spatial value. For this reason, it is possible to provide effective development projects and houses that take advantage of such features in narrow or densely populated areas.

  Specifically, the shaft set 70 of the comparative example has a thinner column than that of the shaft set 60, so that many bearing walls and the like are used to ensure strength. For this reason, the space is partitioned finely. On the other hand, according to the shaft set 70 using the columns 53a and 53b of the present embodiment, since the strength is ensured by the columns 53a and 53b, a large space can be taken.

<Fifth application example>
FIG. 13 is a three-view diagram illustrating a fifth application example.
In FIG. 13, a front view, a side view, and a plan view are shown.
The module 80 of the fifth application example includes a base 81, a beam 82, and pillars 83a and 83b. The length between the base 81 and the beam 82 is 2587 mm as an example.

  Openings formed (defined) in a region surrounded by the base 81, the beam 82, and the columns 83a and 83b are provided with face members (structural plywood) 84a and 84b having a thickness of 24 mm. It has been. These face members 84a and 84b are fastened to the fastening members 86a and 86b by a plurality of hybrid washers 85 and bolts 3p. The fastening members 86a and 86b and the pillars 83a and 83b are fixed by a plurality of hybrid washers 87 and bolts 3n. Thereby, the face materials 84a and 84b are fastened to the pillars 83a and 83b via the fastening members 86a and 86b that fasten the face materials 84a and 84b.

  A wooden structure 1e is formed by the pillar 83a, the fastening member 86a, the hybrid washer 87, the bolt 3n, and the insertion member 13. A wooden structure 1f is formed by the pillar 83b, the fastening member 86b, the hybrid washer 87, the bolt 3n, and the insertion member 13.

  The structures of the wooden structures 1e and 1f are the same as the wooden structures 1, 1a and 1b described above. For example, the fastening member 86a and the pillar 83a are fixed with a plurality of bolts 3n at intervals of 200 mm. On the surfaces of the fastening member 86a and the pillar 83a that are opposed to each other, recesses that are at least partially opposed to each other are provided at predetermined intervals. A rectangular parallelepiped insertion member 13 is disposed in an opening formed by these recesses facing each other.

  The plan view of the module 80 shown in the lower part of FIG. 13 shows the arrangement pattern of the bolts 3n of the pillars 83a and 83b and the insertion members 13. As shown in the plan view, in the module 80 of the present embodiment, the face material 84a is fastened to the fastening members 86a and 86b by the bolt 3p, so that the face 84a1 of the face material 84a is replaced with the face 83a1 of the column 83a. And it is substantially parallel to the surface 83b1 of the pillar 83b.

  For example, when the face materials 84a and 84b are directly struck to the pillars 83a and 83b using a nail or the like, the diameter of the nail is small, and thus the face materials 84a and 84b may come off the pillars 83a and 83b when a horizontal load is applied. there were. In order to suppress this, if the diameter of the nail is increased, the number of nails is increased, or the thickness of the face members 84a and 84b is increased, the area protruding from the pillars 83a and 83b becomes larger.

  According to the module 80, it is possible to increase the strength in the direction in which the pillar 83a and the fastening member 86a, the pillar 83b and the fastening member 86b, and the respective engaging portions slide sideways. Further, the face materials 84a and 84b are fastened to the fastening members 86a and 86b, and the thickness of the face materials 84a and 84b is increased (for example, 24 to 28 mm) by suppressing unevenness in the plan view and the side view of the module 80. ), The appearance can be made clear. Further, by increasing the thickness of the face members 84a and 84b, it is possible to suppress the face members 84a and 84b from being detached from the pillars 83a and 83b using the bolt 3n and the hybrid washer 85 instead of the nail.

<Sixth application example>
FIG. 14 is a diagram for explaining the wooden structure of the sixth application example.
The module 90 of the sixth application example includes wooden structures 1g, 1h, and 1i connected in series. Since the lengths h5 and h6 of the wooden structures 1g and 1i are 2500 mm, and the length h7 of the wooden structure 1h is 5000 mm, the length of the module 90 is 10,000 mm.
In FIG. 14, the figure which expanded a part of wooden structure 1h and the wooden structure 1i is shown by the balloon.

  The basic structure of each of the wooden structures 1g, 1h, 1i is the same as that of the wooden structure 1a. For example, the wooden structure 1h includes square members 14a, 14b, and 14c. As an example, the square members 14a and 14c have a thickness of 105 mm, and the square member 14b has a thickness of 390 mm. Through holes for inserting bolts 3q are provided at predetermined positions of the square members 14a, 14b, and 14c. The bolts 3q are inserted into the through holes, and the square members 14a, 14b, and 14c are fixed to each other by being tightened by the hybrid washers provided at the upper part of the square member 14a and the lower part of the square member 14c.

Further, on the surfaces of the square members 14a, 14b, and 14c that face each other, that is, the lower surface of the square member 14a, the upper and lower surfaces of the square member 14b, and the upper surface of the square member 14c, there are predetermined recesses (grooves) that at least partially face each other. It is provided at every interval.
A rectangular parallelepiped insertion member 15 is disposed in an opening formed by these recesses facing each other.
