And it does not jump out of the wedge window hole c ′.

  Therefore, the connection between the beam c and the column a (or between the column and the base) can be made tight and strong as set.

  A pair of wedge guide pieces d, d 'are mounted in the wedge window holes b', c ', and a driving laterally long wedge e is driven between the pair of wedge guide pieces d, d'.

  This embodiment relates to a joint connection structure of a beam and a column, which generally includes a fitting b attached to the column a fitting and supporting an end of the beam c, and a wedge of the fitting b. By driving a laterally long wedge e between a pair of wedge guide pieces d, d 'mounted on the window hole b' for wedges and the window hole c 'for wedges at the end of the beam c, The pillar a and the beam c are tightly and firmly joined and connected, and the most important point is that the laterally long wedge e is driven between the pair of wedge guide pieces d and d ′.

  The joining bracket b is formed in an L shape by the upright plate 1 and the bottom plate 2, and a core plate 3 is established and fixed between the inner surface of the upright plate 1 and the upper surface of the bottom plate 2, and is approximately at the center of the core plate 3. The rectangular wedge window hole b ′ is opened.

  The joining metal fitting b is fitted and fixed to the pillar a with a plurality of bolts 5 and nuts 6 by fitting the upright plate 1 into a shallow recess 4 formed in a required position on the side surface of the pillar a. Is done.

The beam c is formed by excavating a shallow concave portion 7 having the same shape and the same size as that required for receiving the bottom plate 2 of the joint fitting b on the lower surface c1 of the end portion. In the center (along the major axis of c), a fitting vertical groove 8 having substantially the same shape and the same size as that required for receiving the core plate 3 of the joint metal fitting b is provided. The excavation is performed in a state where the shallow bottom recess 7 is open to communicate with.
In addition, the beam c has the same shape and size as the wedge window hole b ′ opened on both side surfaces c4 and c5 at the end thereof, and the wedge window hole c ′ having a cylindrical hole shape is inserted into the fitting vertical groove. Excavation is formed in a state of crossing 8.

  The beam c has a shallow concave recess 7 fitted to the bottom plate 2 and a fitting vertical groove 8 fitted to the core plate 3 with respect to the above-mentioned joining bracket b fixedly attached to the column a, and a wedge. It is mounted and supported in a state where the window hole c ′ for use is substantially aligned with the window hole for wedge b ′.

  At this time, a gap f1 is formed between the end surface c2 of the beam c and the opposite side surface of the column a and the inner surface of the upright plate 1 of the joint metal b, and from the column a of the shallow recess 7 of the beam c. The inner surface on the far side has a gap f2 between the end surface of the bottom plate 2 of the joint fitting b, and the hole edge on the side far from the pillar a of the wedge window hole b ′ formed in the core plate 3 of the joint fitting b. b′1 is slightly protruded into the wedge window hole c ′ of the beam c, and the hole edge b′2 on the side close to the pillar a is positioned outside the wedge window hole c ′, and there is a gap between them. A gap f4 is made between the inner back portion of the fitting vertical groove 8 of the beam c and the rear end 3 ′ of the core plate 3 (FIG. 2).

Next, the wedge guide pieces d and d 'and the driven long wedge e will be described.
The wedge guide piece d has a length L from the proximal end 9 to the distal end 10 substantially the same as the width of the beam c (between the side surfaces c4 and c5) and a height h of the wedge window hole b ′ and the wedge window. It is a hexahedron made of metal such as iron, which is substantially the same as the height of the hole c ′. That is, the width w2 on the distal end 10 side is made wider and thicker than the width w1 on the proximal end 9 side, the inner surface 11 on one side is roughened, and the longitudinal groove 12 is dug in the center in the longitudinal direction of the outer surface. Has been established. And the latching | locking part 13 is protrudingly formed and formed in the inner surface 11 side of the front-end | tip 10 (FIG. 5).

Further, the wedge guide piece d ′ has the same height as the height h of the wedge guide piece d, and therefore, iron or the like whose height is substantially the same as the height of the wedge window hole b ′ and the wedge window hole c ′. It is a metal hexahedron. As in the wedge guide piece d, the width w4 on the tip 15 side is made wider and thicker than the width w3 on the base end 16 side, and the inner surface 14 on one side is made rough.
However, unlike the wedge guide piece d, no locking portion is formed at the distal end 15, and the length L ′ from the base end 16 to the distal end 15 is larger than the length L of the wedge guide piece d. The tip 15 is shortened by not forming a locking portion (FIG. 5).

  The driven laterally long wedge e is a metal plate such as iron having a square cross section whose length is the same as the length L ′ of the wedge guide piece d ′, and its height h ′ is set to the wedge guide piece d. , D ′ is the same as the height h, and the width is tapered by gradually narrowing the width w6 on the distal end 18 side compared to the width w5 on the proximal end 17 side. Further, both side surfaces 19 and 19 are rough surfaces (FIG. 5).

  The wedge guide pieces d and d 'and the driven long wedge e are mounted on the metal fitting b fixedly attached to the column a and supported by the beam c. Thus, the column a and the beam c are tightly connected to each other through the joint fitting b and are firmly joined and connected.

  For this purpose, first, the wedge guide pieces d and d ′ are arranged together or individually with the inner surfaces 11 and 14 facing each other (FIGS. 1 to 3), and the wedge window hole b ′ and the wedge window hole c. The longitudinal groove 12 of the wedge guide piece d is inserted into the hole edge b′1 of the core plate 3 of the joint metal fitting b (a little protruding into the wedge window hole c ′ of the beam c as described above). And the tip 15 of the wedge guide piece d ′ is engaged with the locking portion 13 of the wedge guide piece d. As a result, the wedge driving space g between the wedge guide pieces d and d ′, in which the width on the inner back side (side c5 side of the beam c) is reduced and the width on the front side (side c4 side of the beam c) is increased. Formed (FIG. 2).

Thereafter, the driven horizontally long wedge e is driven into the wedge driving empty space g between the wedge guide pieces d and d ′ while being guided by polymerization.
By this driving, the entire beam c gradually moves forward while reducing the gaps f1 to f4 along the core plate 3 of the joint metal fitting b, and finally presses the end surface c2 against the side surface of the column a. .
When the pressure contact is complete, the distal end 18 of the driven long wedge e abuts against the locking portion 13 of the wedge guide piece d, and the end surface of the proximal end 17 is used as the proximal end of the wedge guide pieces d and d ′. Each of the related parts is designed to be flush with the end faces of 9, 16 and hence the side face c4 of the beam c (FIG. 3).

In this embodiment, the driven long wedge e is driven while being guided by the wedge guide pieces d and d ′, and the entire beam c is moved forward to the column a side via the wedge guide piece d ′ on the side close to the column a. Let
Therefore, the driven long wedge e does not bite or deform the inner surface of the wedge window hole c ′ of the beam c.

  Further, the longitudinal groove 12 of the wedge guide piece d is fitted into the hole edge b′1 of the core plate 3 of the joint metal b, and the tip 15 of the wedge guide piece d ′ is fitted to the locking portion 13 of the wedge guide piece d. The wedge guide piece d ′ moves together in the driving direction as the driven horizontal wedge e is driven, and jumps outward from the wedge window hole c ′. Nor.

  Therefore, the joint connection between the beam c and the column a can be made tight and strong as set. In particular, since the inner surfaces 11 and 14 of the wedge guide pieces d and d 'and the both side surfaces 19 and 19 of the driven long wedge e are roughened, the frictional resistance between them is great and the wooden building vibrates due to an earthquake or the like. Even if there is, there is no risk of inadvertent relaxation.

  As mentioned above, although the case where the column a and the beam c were joined and connected was explained, the present invention can be applied to the joining and connection of the column and the girder, and of course, the joining bracket b is attached to the base (not shown), By adopting a structure in which the lower end portion of the pillar a is fitted to the joint fitting b, the present invention can be similarly applied to the case where the base and the pillar are joined and connected.

It is a perspective view of the decomposition | disassembly state of the joint connection structure of the beam and column which concerns on the Example of this invention. FIG. 3 is a cross-sectional plan view of a state in which a pair of wedge guide pieces are inserted into a wedge window hole in the joint connection structure. FIG. 6 is a cross-sectional plan view of a state in which a horizontally long wedge is driven between the pair of wedge guide pieces. It is a side view same as the above. It is a perspective view of a pair of wedge guide piece and driving | running | working horizontally long wedge of a present Example.
