Description

  The present invention relates to a joint structure used for a gate-shaped wood frame as a building structure.

  The building structure using the conventional portal ramen frame shown in FIGS. 12 to 14 includes a portal wooden frame F having an opening width of the interval between the left and right support walls (one span) at the front part of the first floor portion. Are arranged side by side on the foundation B1, and a space part without a wall set or pillar is formed inside, and the first floor set is formed on the base B2 by the frame wall construction method with the wood frame F interposed. The first floor wall set including the load bearing walls is attached to the left and right side wall portions and the rear wall portion, and corner posts or the like are attached to the intersections of the load bearing walls. On the assembled first-floor wall assembly, a second-floor floor assembly is constructed, on which a corner pillar is attached, a second-floor wall assembly including a load-bearing wall is constructed. A floor assembly, a three-story wall assembly is constructed, and a roof assembly R is constructed.

  As shown in FIGS. 12, 13, and 14, the portal-shaped wood frame F includes two vertical members F1 and F2, and an L-shaped joining metal plate S1 on the two vertical members F1 and F2. It consists of the joined cross member F3. The L-shaped joining metal plate S1 is inserted into a slit formed and communicated with the longitudinal members F1, F2 and the transverse member F3, and joins and fixes the longitudinal members F1, F2 and the transverse member F3. Further, as shown in FIG. 13, auxiliary pillars A1 and A2 are erected on the front-rear direction surface of the cross member F3 constituting the portal frame F, and are fixed to the portal frame F by a metal fitting S2 or the like. Further, the horizontal members W1 and W2, which are trunk differences, are connected and fixed to the front and rear surfaces of the supporting pillars A1 and A2 via a battledore bolt (one-handed bolt) S3 and a metal fitting S4. .

In such a structure, the width of the portion inserted into the vertical members F1 and F2 of the joining metal plate S1 is equal to the width of the longitudinal members F1 and F2, and the outer end of the joining metal plate S1 and the transverse member F3. And the vertical members F1 and F2 are arranged and fixed so as to coincide with the outer ends of the vertical members F1 and F2. This is because if the battledore bolt S3 or the like is directly inserted in the front-rear direction, the joined metal plate S2 interferes and cannot be inserted deeply. That is, the auxiliary pillars A1 and A2 are for preventing the joining fitting S1 and the joining fitting such as a battledore bolt inserted in the front-rear direction from being buffered.

Since a joining metal fitting 6 for joining a horizontal member 5A such as a trunk difference is inserted into a portion of the wood frame where a predetermined interval D is formed, as in the prior art. In addition, since no additional pillar is required when using the joint fitting 6, construction workability and economic efficiency when joining the horizontal member 6 </ b> A such as a trunk difference to the wooden frame 1 are significantly improved. In particular, the work burden of maintaining the accuracy required according to the presence and number of accessory posts is greatly reduced.

  The portal frame of the present invention is not only a portal frame 1A having an opening width of 1 span incorporated in a part of one direction of the first floor of the building, that is, the front (front-rear) direction, but also a portal frame 1B, etc. It is also possible to use a 1-span type portal frame 1B using a through pillar up to the second floor as a vertical member, and it is also possible to use a one-span type portal frame using a through column up to the third floor as a vertical member. .

  That is, as shown in FIG. 8, a pair of vertical members 11A and 11B erected on the building foundation 2 and the upper surfaces of the vertical members 11A and 11B are joined to each other via a single plate-like joint fitting 12. One cross member 13 and at least one of the vertical members 11A and 11B are joined to each other through at least one other plate-like joint fitting 12 ′ and parallel to the cross direction of the cross member 13 in the downward direction. In a portal-shaped wooden frame formed with two other horizontal members 13 ', a horizontal member (both horizontal members) joined to the front or (and) the rear surface of the side end of one horizontal member 13 of the wooden frame Material) (not shown), and the one plate-like joint metal fitting 12 is inserted into a slit G formed at the upper part of the longitudinal members 11A and 11B and at the side end of the one transverse member 13. In addition, the side end 12E of the plate-shaped joint fitting 12 is the side end of the cross member 13. The joint fitting 6 (not shown) is fixedly installed inward from 13E via a predetermined distance D and is inserted into an insertion hole 14 formed in a portion of the one cross member 13 where the predetermined distance D is formed. ), The horizontal members (both horizontal members) and one horizontal member 13 are joined to each other and joined to the front surface and / or the rear surface of the vertical member 11A of the wooden frame. The joining structure of the member 13 'is such that the other plate-like joining fitting 12' is inserted into the slit G formed at the side end of the longitudinal member 11A and the other transverse member 13 ', and the plate-like joining. The side end 12E ′ of the metal fitting 12 ′ is fixedly installed inward from the both ends of the vertical members 11A and 11B via a predetermined distance D, and the predetermined distance D is formed in the vertical members 11A and 11B. Other joint fitting 6 '(not shown) inserted into the insertion hole 14' formed in It can also be set as the joining structure for buildings characterized by joining said other horizontal member 13 'and the vertical members 11A and 11B through this, In this case, it is the several plate-shaped joining metal fitting 12 (In FIG. 8, one set on the left and right is six pieces for the third floor), and a plurality of fittings 6 inserted into the insertion holes 14 (12 pieces in the case where two pieces are used for one joining portion) are used.

  The shape of the bonding metal plate 12 is not limited to the above. For example, as shown in FIGS. 9 and 10, the outer corner of the bonding metal plate 12 that is L-shaped when viewed in the front-rear direction is cut into a rectangular shape. Thus, it is also possible to form a predetermined interval D that is a portion where the joining metal plate 12 is not interposed in the front-rear direction, form an insertion hole therethrough, and insert a joining metal fitting.

  Further, for example, as shown in FIG. 11, a predetermined interval D that is a portion where the outer corner portion of the L-shaped joining metal plate 12 in the front-rear direction is cut out in a triangular shape and the joining metal plate 12 is not interposed in the front-rear direction. It is also possible to form a through hole for insertion in the front-rear direction and insert a joint fitting. This embodiment serves to guide moisture outward by forming an outwardly sloping surface of the gate-shaped wood frame.
