Description

[Technical field]

[0001] The present invention relates to a wooden column joint positioning structure and a wooden column joint construction method. [Background technology]

[0002] In the column joints of precast concrete column components, there is a joint structure in which the upper and lower column components are positioned by connecting erection pieces that are bolted to the ends of the upper and lower column components (see, for example, Patent Document 1).

[0003] There is also a hold-down metal fitting that secures the base of a wooden pillar to a foundation (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] International Publication No. 2014 / 083602 [Patent Document 2] JP 2007-205064 A Summary of the Invention [Problem to be solved by the invention]

[0005] Recently, wooden structures have tended to become larger in size. In such large-scale wooden structures, there is a possibility that upper and lower wooden columns will be connected by column joints on the construction floor. In this case, it is considered to provide an erection piece at the end of each of the upper and lower wooden columns, and to position the upper and lower wooden columns by connecting these erection pieces.

[0006] However, it is not possible to weld erection pieces to wooden columns like steel columns, making it difficult to position the upper and lower wooden columns.

[0007] In consideration of the above, an object of the present invention is to position upper and lower wooden columns at a column joint. [Means for solving the problem]

[0008] The wooden column joint positioning structure described in claim 1 comprises a lower erection piece fixed to the upper end of the lower wooden column by a through bolt or a screw member, an upper erection piece fixed to the lower end of the upper wooden column placed on the upper end surface of the lower wooden column by a through bolt or a screw member, and a connecting member connecting the lower erection piece and the upper erection piece.

[0009] According to the wooden column joint positioning structure of claim 1, the lower erection piece is fixed to the upper end of the lower wooden column by a through bolt or screw member. On the other hand, the upper erection piece is fixed to the lower end of the upper wooden column placed on the upper end surface of the lower wooden column by a through bolt or screw member. These lower erection pieces and upper erection pieces are connected by a connecting member.

[0010] This positions the upper wooden column relative to the lower wooden column. In this state, the lower wooden column and the upper wooden column can be joined together easily, improving the workability of the upper wooden column.

[0011] In addition, by using a through bolt or screw member, the lower erection piece can be easily fixed to the upper end of the lower wooden column, and the upper erection piece can be easily fixed to the lower end of the upper wooden column. Therefore, the workability of the upper wooden column is further improved.

[0012] Furthermore, after the upper wooden column is installed, the lower and upper erection pieces can be removed from the lower and upper wooden columns by removing the through bolts or screw members. Therefore, the design of the lower and upper wooden columns is improved.

[0013] The wooden column joint positioning structure described in claim 2 is the wooden column joint positioning structure described in claim 1, in which the connecting member has an adjustment mechanism that can adjust at least one of the level and position of the upper wooden column relative to the lower wooden column.

[0014] According to the wooden column joint positioning structure of claim 2, the connecting member has an adjustment mechanism. The adjustment mechanism is capable of adjusting at least one of the level and planar position of the upper wooden column relative to the lower wooden column. Therefore, the workability of the upper wooden column is further improved.

[0015] The wooden column joint positioning structure described in claim 3 is a wooden column joint positioning structure described in claim 1 or claim 2, which comprises a connecting bar that is inserted into a lower insertion hole formed in the upper end surface of the lower wooden column and an upper insertion hole formed in the lower end surface of the upper wooden column, and a filler that is filled in the lower insertion hole and the upper insertion hole and joins the lower wooden column and the upper wooden column to the connecting bar.

[0016] According to the wooden column joint positioning structure of claim 3, the connecting bars are inserted into the lower insertion holes formed in the upper end surface of the lower wooden column and the upper insertion holes formed in the lower end surface of the upper wooden column. These lower insertion holes and upper insertion holes are filled with a filler material. This joins the lower wooden column and the upper wooden column to the connecting bars. In other words, the lower wooden column and the upper wooden column are joined via the connecting bars and the filler material.

[0017] As described above, the connecting bars are inserted into the lower and upper insertion holes and are not exposed to the outside of the lower and upper wooden columns, so that the lower and upper wooden columns can be joined while improving the design of the lower and upper wooden columns.

[0018] The construction method of the wooden column joint described in claim 4 includes an insertion process of inserting connecting bars into a plurality of lower insertion holes formed on the upper end surface of the lower wooden column, an upper wooden column erection process of placing the lower end surface of the upper wooden column on the upper end surface of the lower wooden column and inserting the connecting bars protruding from the upper end surface of the lower wooden column into the upper insertion holes formed on the lower end surface of the upper wooden column, a positioning process of connecting a lower erection piece bolted to the upper end of the lower wooden column and an upper erection piece bolted to the lower end of the upper wooden column, and a joining process of filling the lower insertion hole and the upper insertion hole with a filler material and joining the lower wooden column and the upper wooden column to the connecting bars.

[0019] According to the wooden column joint construction method of claim 4, in the inserting step, the connecting bars are inserted into the lower insertion holes formed in the upper end surface of the lower wooden column.

[0020] Next, in the upper wooden pillar erection process, the lower end surface of the upper wooden pillar is placed on the upper end surface of the lower wooden pillar, and the connecting bars protruding from the upper end surface of the lower wooden pillar are each inserted into the upper insertion holes formed in the lower end surface of the upper wooden pillar.

[0021] Next, in the positioning process, the lower erection piece fixed to the upper end of the lower wooden column by a through bolt or screw member is connected to the upper erection piece fixed to the lower end of the upper wooden column by a through bolt or screw member. This positions the upper wooden column relative to the lower wooden column.

[0022] Next, in the joining process, a filler is filled into the lower insertion hole and the upper insertion hole to join the lower wooden column and the upper wooden column to the connecting bar.

[0023] In this way, in the positioning process, the upper wooden column is positioned relative to the lower wooden column, and in the joining process, the lower wooden column and the upper wooden column are joined with connecting bars, making it possible to easily join the lower wooden column and the upper wooden column, thereby improving the workability of the upper wooden column.

[0024] In addition, by using a through bolt or screw member, the lower erection piece can be easily fixed to the upper end of the lower wooden column, and the upper erection piece can be easily fixed to the lower end of the upper wooden column. Therefore, the workability of the upper wooden column is further improved.

[0025] Furthermore, after the upper wooden column is installed, the lower and upper erection pieces can be removed from the lower and upper wooden columns by removing the through bolts or screw members. Therefore, the design of the lower and upper wooden columns is improved. Effect of the Invention

[0026] As described above, according to the present invention, upper and lower wooden columns can be positioned at a column joint. [Brief description of the drawings]

[Figure 6] 6 is a cross-sectional view taken along line 6-6 in FIG. 5. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] Hereinafter, one embodiment will be described with reference to the drawings.

[0029] 1 shows a lower wooden column 20 and an upper wooden column 40 constructed by the wooden column joint construction method according to this embodiment. The lower wooden column 20 and the upper wooden column 40 constitute, for example, a wooden column 10 of a large-scale wooden structure.

[0030] The lower wooden column 20 and the upper wooden column 40 are made of wood materials such as laminated lumber, CLT, LVL, etc. The lower wooden column 20 and the upper wooden column 40 are formed in a square pillar shape. The cross-sectional shape and cross-sectional area of ​​the lower wooden column 20 and the upper wooden column 40 are approximately the same.

[0031] 2, a plurality of lower insertion holes 22 are formed on the outer periphery of the upper end surface 20U of the lower wooden column 20. The plurality of lower insertion holes 22 are arranged at intervals in the circumferential direction of the lower wooden column 20. Each of the plurality of lower insertion holes 22 has a bottom and is a circular hole extending downward from the upper end surface 20U of the lower wooden column 20. The lower parts of the connecting bars 30 are inserted into the lower insertion holes 22, respectively.

[0032] 1, the multiple connecting bars 30 are formed, for example, by deformed reinforcing bars. The upper portion of each connecting bar 30 extends upward from the upper end surface 20U of the lower wooden column 20. The lower end surface 40L of the upper wooden column 40 is placed on the upper end surface 20U of the lower wooden column 20.

[0033] A plurality of upper insertion holes 42 are formed in the lower end surface 40L of the upper wooden column 40, which communicate with the plurality of lower insertion holes 22, respectively. The plurality of upper insertion holes 42 are arranged at intervals in the circumferential direction of the upper wooden column 40. Each of the plurality of upper insertion holes 42 has a bottom and is a circular hole extending upward from the lower end surface 40L of the upper wooden column 40. The upper portions of the connecting bars 30 are inserted into each of these upper insertion holes 42.

[0034] Here, a plurality of filling holes 24 are formed in the side surface 20S of the lower wooden column 20, each of which is connected to the plurality of lower insertion holes 22. Filler material 32 is filled from these filling holes 24 into each of the plurality of lower insertion holes 22 and the upper insertion hole 42.

[0035] In addition, a plurality of discharge holes 44 are formed on the side surface 40S of the upper wooden column 40, each of which is connected to a plurality of upper insertion holes 42. By discharging the filler material 32 filled in the upper insertion holes 42 from these discharge holes 44, it is possible to confirm that the filler material 32 has been filled into each of the lower insertion holes 22 and the upper insertion holes 42.

[0036] The filler 32 is, for example, an adhesive such as epoxy resin. The filler 32 joins the lower part of the connecting bar 30 to the lower wooden column 20, and joins the upper part of the connecting bar 30 to the upper wooden column 40. In this way, the lower wooden column 20 and the upper wooden column 40 are joined via the multiple connecting bars 30 and the filler 32.

[0037] (Wooden column joint positioning structure) Next, the wooden column joint positioning structure according to this embodiment will be described.

[0038] As shown in Fig. 3 and Fig. 5, the wooden column joint positioning structure according to this embodiment is a temporary positioning structure that fixes (temporarily fixes) the upper wooden column 40 to the lower wooden column 20 during construction of the lower wooden column 20 and the upper wooden column 40, and positions the upper wooden column 40 relative to the lower wooden column 20. This wooden column joint positioning structure includes a plurality of lower erection pieces 50L, a plurality of upper erection pieces 50U, and a plurality of erection jigs 70 (see Fig. 5). The erection jig 70 is an example of a connecting member.

[0039] (Lower erection piece) As shown in Figures 3 and 4, multiple lower erection pieces 50L are fixed to each side surface 20S at the upper end of the lower wooden column 20. The lower erection pieces 50L arranged on both sides of the lower wooden column 20 form a pair and are fixed to the side surfaces 20S on both sides of the lower wooden column 20 by multiple through bolts 60 and nuts 62 that penetrate the upper end of the lower wooden column 20 in the horizontal direction.

[0040] 4, the through-bolts 60 are arranged to intersect in a plan view. Each through-bolt 60 is inserted into a through-hole 64 that passes laterally through the upper end of the lower wooden pillar 20. Both ends of each through-bolt 60 protrude from the side surface 20S of the lower wooden pillar 20.

[0041] The lower erection piece 50L has a base plate portion 52 and a flange portion 56. The base plate portion 52 is formed of a steel plate or the like, and is disposed along the side surface 20S at the upper end portion of the lower wooden column 20. In addition, the base plate portion 52 has a plurality of mounting holes 54 formed therein.

[0042] The mounting holes 54 are circular through-holes that penetrate the base plate portion 52 in the thickness direction. Ends of through-bolts 60 are inserted into the mounting holes 54, respectively. By tightening nuts 62 onto the ends of the through-bolts 60, the base plate portion 52 is fixed to each side surface 20S at the upper end portion of the lower wooden column 20.

[0043] 3, the flange portion 56 is formed of a steel plate or the like, and is disposed along the vertical direction. The flange portion 56 is provided in a rib shape on the outer surface of the base plate portion 52, and protrudes outward from the base plate portion 52. The flange portion 56 is formed with a hanging hole 58 to which a hanging material of a lifting machine (not shown) is attached. The hanging hole 58 can be omitted.

[0044] (Upper erection piece) A plurality of upper erection pieces 50U are fixed to each side surface 40S at the lower end of the upper wooden column 40. The upper erection pieces 50U arranged on both sides of the upper wooden column 40 form a pair and are fixed to the side surfaces 40S on both sides of the upper wooden column 40 by a plurality of through bolts 60 and nuts 62 that penetrate the lower end of the upper wooden column 40 in the horizontal direction.

[0045] In this embodiment, the upper erection piece 50U and the lower erection piece 50L are configured symmetrically in the vertical direction. Therefore, the description of the configuration of the upper erection piece 50U will be omitted. In addition, the configurations of the upper erection piece 50U and the lower erection piece 50L may be different.

[0046] (Erection jig) As shown in Fig. 5, the erection jig 70 is a jig that connects the lower erection piece 50L and the upper erection piece 50U and positions the upper wooden column 40 relative to the lower wooden column 20. This erection jig 70 has a jig body 72, a level adjustment mechanism 80, and a plane position adjustment mechanism 90. The level adjustment mechanism 80 and the plane position adjustment mechanism 90 are examples of adjustment mechanisms.

[0047] The jig body 72 is formed in a frame shape extending in the vertical direction, and the lower erection piece 50L and the upper erection piece 50U can be inserted inside it. In addition, the jig body 72 is provided with a fixing bolt 74 that fixes the upper erection piece 50U. The jig body 72 is provided with a level adjustment mechanism 80 and a plane position adjustment mechanism 90.

[0048] (Level adjustment mechanism) The level adjustment mechanism 80 is a mechanism for adjusting the level (height) of the upper erection piece 50U relative to the lower erection piece 50L. This level adjustment mechanism 80 has a push-up cam 82 and a level adjustment bolt 84.

[0049] The push-up cam 82 is rotatably supported in the vertical middle of the jig body 72 and is disposed between the lower erection piece 50L and the upper erection piece 50U. This push-up cam 82 pushes up the upper erection piece 50U relative to the lower erection piece 50L as it rotates.

[0050] The level adjustment bolt 84 abuts against the push-up cam 82 according to the amount of screwing, and adjusts the amount of rotation of the push-up cam 82, that is, the amount of pushing up of the upper erection piece 50U relative to the lower erection piece 50L. This adjusts the level and inclination of the upper wooden column 40 relative to the lower wooden column 20. The level adjustment mechanism 80 may be omitted.

[0051] (Plane position adjustment mechanism) The plane position adjustment mechanism (joint misalignment adjustment mechanism) 90 adjusts the position of the flange portion 56 of the upper erection piece 50U in the thickness direction relative to the flange portion 56 of the lower erection piece 50L. This plane position adjustment mechanism 90 has a pair of position adjustment bolts 92.

[0052] As shown in Fig. 6, a pair of position adjustment bolts 92 are provided at the bottom of the jig body 72 and grip the flange portion 56 of the lower erection piece 50L from both sides. This pair of position adjustment bolts 92 adjusts the position of the flange portion 56 of the jig body 72 in the thickness direction (arrow W1 direction or arrow W2 direction) relative to the flange portion 56 of the lower erection piece 50L according to the difference in the amount of each screwing. This adjusts the planar position (joint misalignment) of the upper wooden column 40 relative to the lower wooden column 20. The planar position adjustment mechanism 90 may be omitted.

[0053] (Wooden column joint construction method) Next, an example of a construction method for a wooden column joint according to this embodiment will be described.

[0054] (Lower wooden pillar construction process) First, in the lower wooden column erection process, the lower wooden column 20 is lifted by a lifting machine (not shown) or the like and erected in a predetermined position. In addition, a plurality of lower insertion holes 22 and a plurality of filling holes 24 are formed in advance on the upper end surface 20U of the lower wooden column 20. In addition, a lower erection piece 50L is fixed in advance to each side surface 20S of the upper end portion of the lower wooden column 20.

[0055] (Insertion process) Next, in the insertion process, the lower parts of the multiple connecting bars 30 are inserted into the multiple lower insertion holes 22 formed in the upper end surface 20U of the lower wooden column 20. Then, the upper parts of the multiple connecting bars 30 are made to protrude upward from the upper end surface 20U of the lower wooden column 20.

[0056] In addition, the connecting bar 30 may be inserted into the lower insertion hole 22 formed in the upper end surface 20U of the lower wooden pillar 20 before the lower wooden pillar 20 is erected.

[0057] (Upper wooden pillar construction process) Next, in the upper wooden column erection process, the upper wooden column 40 is lifted up by a lifting machine (not shown) or the like, and the lower end surface 40L of the upper wooden column 40 is placed on the upper end surface 20U of the lower wooden column 20. At this time, the upper parts of the connecting bars 30 protruding from the upper end surface 20U of the lower wooden column 20 are inserted into the multiple upper insertion holes 42 formed in the lower end surface 40L of the upper wooden column 40.

[0058] In addition, a plurality of upper insertion holes 42 and a plurality of exhaust holes 44 are formed in advance on the lower end surface 40L of the upper wooden column 40. Also, the upper erection piece 50U is fixed in advance to each side surface 40S at the lower end of the upper wooden column 40.

[0059] (Positioning process) Next, in the positioning process, the lower erection piece 50L and the upper erection piece 50U adjacent to each other in the vertical direction are connected by the erection jig 70.

[0060] Specifically, the flange parts 56 of the lower erection piece 50L and the upper erection piece 50U adjacent to each other in the vertical direction are inserted into the inside of the jig body 72 of the erection jig 70, and the fixing bolt 74 and the pair of position adjustment bolts 92 are tightened. As a result, the flange parts 56 of the lower erection piece 50L and the upper erection piece 50U are connected to each other via the jig body 72.

[0061] Furthermore, the amount of screwing in of the level adjustment bolts 84 is increased or decreased as necessary to adjust the level and inclination of the upper wooden pillar 40 relative to the lower wooden pillar 20. Furthermore, the amount of screwing in of the pair of position adjustment bolts 92 is increased or decreased to adjust the planar position (joint misalignment) of the upper wooden pillar 40 relative to the lower wooden pillar 20.

[0062] (Joining process) Next, in the joining process, the filler 32 is filled into the lower insertion holes 22 and the upper insertion holes 42 through the filling holes 24 formed in the side surface 20S of the lower wooden column 20, and then hardened. As a result, the lower wooden column 20 and the upper wooden column 40 are joined via the connecting bars 30 and the filler 32.

[0063] At this time, the filling material 32 filled in the upper insertion hole 42 is discharged through the discharge hole 44 formed in the side 40S of the upper wooden column 40 to confirm that the filling material 32 has been filled into the lower insertion hole 22 and the upper insertion hole 42.

[0064] (Removal process) Next, in the removal process, the fixing bolts 74 and the pair of position adjustment bolts 92 of the erection jig 70 are loosened, and the erection jig 70 is removed from the lower erection piece 50L and the upper erection piece 50U adjacent to each other in the vertical direction.

[0065] Next, remove the nuts 62 from both ends of each through-bolt 60, and remove each lower erection piece 50L and the through-bolt 60 from the upper end of the lower wooden column 20. Similarly, remove each upper erection piece 50U and the through-bolt 60 from the lower end of the upper wooden column 40.

[0066] The through holes 64 for the through bolts 60 formed in the lower wooden pillar 20 and the upper wooden pillar 40 may be blocked with wooden plugs or the like (not shown).

[0067] (Action and Effects) Next, the operation and effects of this embodiment will be described.

[0068] As shown in Fig. 5, according to this embodiment, the lower erection piece 50L is fixed to the upper end of the lower wooden column 20 by a through bolt 60. On the other hand, the upper erection piece 50U is fixed to the lower end of the upper wooden column 40 placed on the upper end surface 20U of the lower wooden column 20 by a through bolt 60 and a nut 62. These lower erection pieces 50L and upper erection pieces 50U are connected by an erection jig 70.

[0069] This positions the upper wooden pillar 40 relative to the lower wooden pillar 20. In this state, the lower wooden pillar 20 and the upper wooden pillar 40 can be joined easily by joining them together. This improves the ease of construction of the upper wooden pillar 40.

[0070] In addition, by using the through bolt 60 and the nut 62, the lower erection piece 50L can be easily fixed to the upper end of the lower wooden column 20, and the upper erection piece 50U can be easily fixed to the lower end of the upper wooden column 40. Therefore, the workability of the upper wooden column 40 is further improved.

[0071] Furthermore, after the upper wooden column 40 is installed, the lower erection piece 50L and the upper erection piece 50U can be removed from the lower wooden column 20 and the upper wooden column 40 by removing the through bolt 60 and the nut 62. Therefore, the design of the lower wooden column 20 and the upper wooden column 40 is improved.

[0072] The erection jig 70 also has a level adjustment mechanism 80 and a planar position adjustment mechanism 90. The level adjustment mechanism 80 is capable of adjusting the level of the upper wooden column 40 relative to the lower wooden column 20. The planar position adjustment mechanism 90 is capable of adjusting the planar position of the upper wooden column 40 relative to the lower wooden column 20. This further improves the ease of construction of the upper wooden column 40.

[0073] Furthermore, the lower wooden column 20 and the upper wooden column 40 are joined via connecting bars 30 and filler material 32. Here, the connecting bars 30 are inserted into the lower insertion holes 22 of the lower wooden column 20 and the upper insertion holes 42 of the upper wooden column 40, and are not exposed to the outside of the lower wooden column 20 and the upper wooden column 40. Therefore, the design of the lower wooden column 20 and the upper wooden column 40 can be improved while the lower wooden column 20 and the upper wooden column 40 are joined.

[0074] (Modification) Next, a modification of the above embodiment will be described.

[0075] In the above embodiment, the connecting member connecting the lower erection piece 50L and the upper erection piece 50U is the erection jig 70. However, the connecting member is not limited to the erection jig 70, and may be, for example, a steel material such as a splice plate that is bolted to the flange parts 56 of the lower erection piece 50L and the upper erection piece 50U.

[0076] In the above embodiment, the lower erection piece 50L is fixed to each side surface 20S at the upper end of the lower wooden column 20 by the through bolt 60. However, the lower erection piece 50L is not limited to the through bolt 60, and may be fixed to each side surface 20S at the upper end of the lower wooden column 20 by a screw member such as a screw bolt or a lag screw.

[0077] Similarly, in the above embodiment, the upper erection piece 50U is fixed to each side surface 40S at the lower end of the upper wooden column 40 by the through bolt 60. However, the upper erection piece 50U is not limited to the through bolt 60, and may be fixed to each side surface 40S at the lower end of the upper wooden column 40 by a screw member such as a screw bolt or a lag screw.

[0078] Although one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, and one embodiment and various modified examples may be used in appropriate combination, and it is of course possible to implement the present invention in various forms without departing from the gist of the present invention.
