It is.

2. Description of the Related Art Conventionally, as a joint structure of this type of wooden structure material, a structure in which a beam abutted against a side surface of a support is joined by a bolt and a plate connected to the bolt (Patent Document 1) is known. This plate is inserted into a vertical slit formed at the end of the beam, with bolts welded to the end. On the support column side of the plate, a fastening piece formed with an internal thread is provided, and a plurality of support column side bolts penetrating the support column are screwed together.

In such a conventional wooden structure joint structure, not only is it not rational in the transmission of gravity, but if a large horizontal force acts on the joint due to an earthquake or typhoon, it will easily deform, The wedge material breaks or the beam splits. For this reason, there is a high possibility that it will collapse easily, and there is a problem that the use of reinforcing materials such as braces cannot be avoided.
In addition, in the conventional horizontal member, it is necessary to carefully select and combine the plate members of each part of the laminated material, which causes waste in wood cutting, which is contrary to the resource saving of wood, and there is a problem of contamination of the indoor environment due to the adhesive. . In addition, the laminated lumber tries to bring wood closer to standardized industrial products such as steel, so the structure is often made of pseudo-steel structure, and the uniqueness of the wooden structure cannot be fully utilized. There was a problem.
Further, the conventional column base structure only serves to prevent the support column from being pulled out from the base, and the rigid connection between the support column and the foundation cannot be obtained. Moreover, since the column base metal fittings are fixedly installed, there is a problem that mortise cannot be placed in the building and the workability is deteriorated.
In addition, the column base bracket has a problem that when the bracket main body is attached to the base in advance, rainwater enters into the bracket main body and eventually causes corrosion of the base and the column.

First, the present invention provides a joint structure of a wooden structure material that forms a semi-rigid joint and enables a wooden ramen frame.
Secondly, a horizontal member that can contribute to resource conservation of wood without damaging the strength and can suppress the occurrence of environmental pollution.
Thirdly, a column base structure that allows mortise into the column in the building without damaging the support strength and a column base bracket that can smoothly drain rainwater that has entered during construction,
And it is making the subject to provide the frame of a wooden building provided with these, and its assembly method.

  The joint structure of the wooden structure material of the present invention is such that the tenon provided at the end of the horizontal member is fitted into the mortise provided in the post, and the post and the end of the horizontal member are respectively fitted to the both ends. In the joint structure of a wooden structure that is tightly attached so as to be pulled by a tension bolt incorporating a tenon, the tenon is constructed with a large tenon or a short tenon with a small torso, and the tenon projecting dimension is slightly smaller than the depth of the tenon hole It is formed long, and the horizontal member is formed with a horizontal member side bolt hole through which the tensile bolt is inserted, and a tool groove for fastening the tensile bolt inserted through the horizontal member side bolt hole, A column-side bolt hole that is positioned coaxially with the horizontal member-side bolt hole and penetrates the column is formed, and tensile bolts are embedded in the column and the horizontal member.

  According to this configuration, the load on the roof or floor (vertical load) received by the horizontal member can be transmitted directly and effortlessly to the column by a tenon, and the bending strength of the column due to the horizontal force caused by an earthquake or the like can be increased. Further, since the tip of the groove is sunk into the support column by fastening the tension bolt, it is possible to absorb the force in the horizontal direction and increase the bonding strength. Furthermore, since the bottom cross-sectional area of the tenon can be increased by large insertion or with a small torso, it is possible to persistently resist deformation due to horizontal external force (wind pressure such as seismic force or typhoon). Moreover, since the tension bolt extends horizontally, the horizontal bolt and the support column are not cracked or sheared by the tension bolt against the horizontal force. Therefore, the mortise will not come out of the mortise, and there is no danger of the building collapsing or collapsing. In addition, since the tension bolt is embedded in the support column and the horizontal member, this does not obstruct the production and the like, and there is no need for fireproof coating.

That is, a sleeve 63 is fitted in each large beam side bolt hole 61 so that a square washer (end washer 53a and intermediate washer 53b) 53 abuts from both sides, and an end tension bolt (both screws) is inserted into the sleeve 63. Bolts 51) 45 are inserted. Each tool groove 62 is a rectangular parallelepiped groove in which the end washer 53a can be set and a wrench (tool) can be operated. The upper tool groove 62 opens on the upper surface of the upper large beam 22, and the lower The tool groove 62 is opened on the lower surface of the lower large beam 23.

  On the other hand, the pillar 11 is formed with a pair of upper and lower pillar side bolt holes 64 that are positioned coaxially with the respective large beam side bolt holes 61 and penetrate horizontally therethrough. Each post-side bolt hole 64 is not provided with a sleeve, but two lag screws 65 that are in contact with each square washer (end washer 53a and intermediate washer 53b) 53 are embedded in the periphery. Yes. That is, the end washer 53a and the intermediate washer 53b are respectively addressed to the outer side and the inner side of the column 11, and two lag screws are provided so as to contact the vertical positions of the inner and outer corner washers 53, respectively. 65 is embedded. As a result, the end washer 53a and the intermediate washer 53b are prevented from being inserted into the support column 11. Although omitted in the drawing, the intermediate washer 53a is embedded in a shallow groove formed in the support column 11 and / or the large beam A. The end tension bolts 45 are not necessarily both screw bolts, and may be full screw bolts or ordinary bolts having a head.

  In the same manner as above, each of the large beams A constituting the trunk difference 12 has a pair of upper and lower large beam side bolt holes 71 through which the intermediate tension bolts 46 are inserted, and upper and lower ends communicating with the end of each large beam side bolt hole 71. A pair of tool grooves 72 are formed. Also in this case, the sleeve 73 is inserted in each large beam side bolt hole 71. However, a retraction bolt hole 74 extending coaxially with the large beam side bolt hole 71 and extending beyond the tool groove 72 is formed on one of the two large beams A (see FIG. 4B). The retraction bolt hole 74 is for receiving the intermediate tension bolt (both screw bolts 61) 46 in one large beam A so as to be in the way prior to tenoning. It is sent toward the large beam side bolt hole 71.

  Similarly to the above, the support column 11 is formed with a pair of upper and lower support column side bolt holes 75 that are positioned coaxially with the respective large beam side bolt holes 71 and penetrate horizontally therethrough. Also in this case, two lag screws 76 that are in contact with each intermediate washer 57 b are embedded around each column side bolt hole 75. Although not shown in the drawing, these intermediate washers 57b are embedded in shallow grooves formed in the support column 11 and / or the large beam A.

  In such a configuration of the joint 10, ten large beams A from three sides are respectively mortised into the support column 11 (details will be described later but not at the same time). At this time, at least the intermediate washer 53b, 57b and The intermediate tension bolt 46 is set in advance before the tenon of the large beam A is fitted into the tenon 41 of the column 11. In the large beam A constituting the end beam 14, after tenoning, two end tension bolts (both screw bolts 51) 45 are inserted from the outside, and a pair of square washers 53 are passed through and tightened by nuts 52 from both sides.

Further, in the two large beams A constituting the trunk difference 12, after tenoning, two intermediate tension bolts (both screw bolts 61) 46 are fed into the other through the retraction bolt holes 74, and a pair of square washers 57 are respectively provided. And is tightened (tightened) by a nut 56. The nuts 52 and 56 are temporarily tightened once, and after the re-installation is completed, final tightening is performed.

  In this way, the three large beams A are fastened so as to be attracted to the support column 11 by the end tension bolts 45 and the intermediate tension bolts 46. Therefore, at the portions of the short tenon 42 and the mortise 41, The support | pillar 11 and each large beam A are joined by a comparatively wide area. For this reason, the pillar 11 and each large beam A form a firm joint shape of semi-rigid joints, and constitute an inferior joint 10 as a wooden ramen that takes advantage of the characteristics as a structural material of wood that easily causes material deformation. can do. In particular, since the short mortise 42 is appropriately recessed into the mortise 41 to withstand this external force against a large horizontal force caused by an earthquake or typhoon, bracing or the like is unnecessary, and a large span wooden building can be constructed. Further, since the end tension bolt 45 and the intermediate tension bolt 46 are embedded in the support column 11 and the large beam A, there is no need for a fireproof coating, and even if a metal material is used, fire resistance and durability are high. The joint 10 can be configured. In the above description, round washers may be used in place of the square washers 29, 53, and 57.

  Next, with reference to FIG. 4, the joint part of the said support | pillar 11 and the underground beam 2 is demonstrated in detail. As described above, the column base 7 is provided at the lower end portion 11 a of the column 11, and the lower end 11 a of the column 11 is embedded in each intersection portion 6 of the underground beam 2 via the column base 7. It is. The intersection portion 6 of the underground beam 2 is a footing, and a triangular column hole 80 for embedding the column base metal 6 is formed in the central portion of the footing. In this case, the column base 7 installed in the column hole 80 is filled with a non-shrinkable mortar 81 after the main shaft set 3 and the cabin set 4 have been rebuilt. And the column base metal fitting 7 after hole filling becomes a form in which the upper end part is slightly exposed on the mortar 81. A plurality of anchor bolts may be provided at the bottom of the column hole 80 for fixing the column base metal 7 with a base plate 84 to be described later.

  The column base 7 includes a rectangular tube-shaped metal fitting body 83 that fits and holds the lower end portion 11 a of the column 11, a base plate 84 that supports the metal fitting body 83 from below, and a space that is horizontally built in the lower portion of the metal fitting body 83.

Is also made of metal such as steel. On the other hand, the lower end portion 11a of the support column 11 is ground into a tenon shape with a stepped portion, the stepped portion is in contact with the upper edge of the metal fitting body 83, and the lower end is in contact with the partition plate 85. It is held by the metal fitting 7. In the state where the lower end portion 11a of the column 11 is fitted to the column base metal 7, each side surface of the column 11 slightly protrudes from each side of the column base metal 7 ((b) in the figure). See), and a water-stop seal is applied to a groove formed over the entire circumference between the upper end of the column base 7.

  The metal fitting body 83 has an inner cross-sectional shape that matches the cross-sectional shape of the lower end portion 11a of the column 11, and is formed, for example, by cutting a square pipe according to its height or bending a steel plate and welding the end portion. ing. In the upper end portion of the metal fitting body 83, insertion holes 91 through which the above-mentioned column fixing bolts (both screw bolts) 87 are inserted are formed in the opposite side plates 83a of the metal fitting body 83, respectively. In this case, a bolt hole 11b connected to the insertion hole 91 is also formed in the lower end portion 11a of the support column 11, and the lower end portion 11a of the support column 11 fitted to the metal fitting body 83 is inserted from the outside of the both side plates 83a. It is fixed by a column fixing bolt 87. Thereby, the lifting of the support | pillar 11 is prevented. On the other hand, a pair of lower drainage holes (bottom drainage holes) 92 are formed at the lower end of the metal fitting body 83 by cutting the opposing side plates 83a into semicircular shapes. Each lower drainage hole 92 communicates the inside and the outside of the metal fitting body 83, drains rainwater collected in the column base metal fitting 7 at the time of construction, and prevents the column 11 from rotting.

  The base plate 84 is formed to be slightly larger than the metal fitting body 83 in plan view, and the lower end of the metal fitting body 83 is welded to the upper surface thereof. Further, the partition plate 85 is welded to the lower inner surface of the metal fitting body 83, and a pair of upper water drain holes (side water drain holes) 93 cut into a semicircular shape are formed on the two opposing sides.
