Description

  The present invention relates to a joint connection structure in a wooden building, and more particularly to an improvement in a joint connection structure between a beam, a girder or a base and a column in a wooden building.

  As this type of joint connection structure in a wooden building, those described in Patent Literature 1 (No. 2565441 Utility Model Registration Gazette) and Patent Literature 2 (No. 2570543 Utility Model Registration Gazette) are known.

  The structure described in Patent Document 1 has a structure in which a beam and a column are joined and connected. The end of the beam is fitted to a joint fitting attached to the pillar, and a wedge window hole provided in the joint fitting and the beam is wedged. The guide piece is inserted and the driven long wedge is driven while sliding one side of the guide wedge on the wedge guide piece, thereby moving the entire beam toward the column with respect to the joint fitting, and the end of the beam. The surface is forcibly joined to the side surface of the column to be firmly connected.

  Further, the one described in Patent Document 2 has a structure in which a pillar and a base are joined and connected, and a lower end portion of the pillar is fitted to a joint fitting attached to the base, and a wedge window hole provided in the joint fitting and the pillar is provided. The wedge guide piece is inserted through the wedge guide piece, and the laterally driven wedge is driven while sliding one side of the wedge guide piece on the wedge guide piece. The lower end surface is forcibly joined to the upper surface of the base so as to be firmly connected.

  That is, in both of the above-mentioned Patent Documents 1 and 2, the driven lateral wedge is driven while one side surface thereof is in sliding contact with the wedge guide piece. In the wedge window hole, the facing surface is pressed while directly contacting the facing surface in the wedge window hole of the beam or column, thereby moving the beam toward the column or directing the column to the base. Has been lowered.

For this reason, the opposed surface of the wedged window hole formed in the beam or the column is bitten or deformed by sliding contact and pressing of the driven long wedge, and the driven horizontal wedge cannot be driven accurately. In some cases, the connection between the column and the column and the connection between the column and the base cannot be made as strong as set.

On the other hand, the present inventor has already proposed a joint connection structure as shown in FIG. 21 (Japanese Patent Application No. 2004-008374).
In the figure, A is a pillar, B is a joint fitting having a window hole B 'for wedges, and C has a fitting portion for receiving the joint fitting B at its end, and crosses the fitting portion. It is a beam having a wedge window hole C ′ that opens on both side surfaces.
D and D 'are a pair of wedge guide pieces provided with wedge guide grooves D1 and D'1 on the inner surfaces facing each other (see FIG. 22), and the heights thereof are the above-mentioned wedge window holes B' and C '. Same as ′.
One of the wedge guide pieces D has the same length as the width of the beam C, and a locking portion D2 protrudes from the tip of the wedge guide piece D, and the wedge window hole B ′ of the joint fitting B is formed on the outer surface thereof. A longitudinal groove D3 is formed to engage with the edge (FIG. 22).
The other wedge guide piece D ′ is shorter than the wedge guide piece D by the thickness of the locking portion D2.

  The joint connection structure using the wedge guide pieces D, D ′ is a joint fitting B fixed to the column A and a wedge window hole B ′, C for a beam C mounted with a fitting portion fitted thereto. The pair of wedge guide pieces D and D ′ are mounted on the ′, and a laterally long wedge E is driven between them while being guided in the wedge guide grooves D1 and D′ 1. For example, the driven horizontally long wedge E does not slide directly on the inner surface of the wedge window hole C ′, so that the inner surface of the wedge window hole C ′ of the beam C does not bite or deform, and the wedge guide Since the piece D engages with the edge of the wedge window hole B ′ of the joint fitting B in the longitudinally recessed groove D3 and the tip of the wedge guide piece D ′ is regulated by the locking portion D2, the driven horizontally long wedge E The wedge guide pieces D and D ′ move together in the driving direction and jump out of the wedge window hole C ′. Migihitsuji thing no.

  However, since the leading edge of the driven horizontal wedge E is restricted by the locking portion D2, the driving stroke is limited to a fixed value. Therefore, the driven horizontal wedge E and the wedge guide pieces D and D ′ are connected to each other. It is necessary to manufacture with an accurate dimension in advance, and there is a case that once the driven laterally long wedge E is later loosened, it may hinder the driving again.

On the other hand, if the present inventor proposed at the same time in the above Japanese Patent Application No. 2004-008374, the hole F2 through which the tip of the horizontally long wedge E is inserted into the engaging portion F1 at the tip of the wedge guide piece F is opened. (FIG. 23) The driving stroke is limited, and it is possible to prevent the driving from being hindered again.
However, manufacturing the wedge guide piece F having a structure in which the locking portion F1 is protruded from the tip portion and the hole F2 is opened therein is time-consuming and increases the cost.

  Therefore, the present invention is easier to manufacture than the prior art, can reduce the manufacturing cost, and does not limit the driving stroke of the driven horizontal wedge, and when the driven horizontal wedge is loosened, it is tightened by driving again. The purpose is to provide a joint connection structure that can be repaired.

The wedge guide pieces d ', g', j ', m', o 'are connected to the longitudinal groove 12 to the wedge window hole b of the fitting b. And the vertical protrusion 13 is fitted to the fitting vertical groove 8 of the beam or girder c and mounted, and this pair of wedge guide pieces d, d ', g, g' , J, j ′, m, m ′, o, o ′, the driven lateral wedges e, i, k, n, p are inserted into the wedge guide grooves 11, 11 ′, 16, 16 ′, 17, 17 ′. , 18 and 18 'while guiding.

  In the joining and linking structure of the present invention wooden structure according to claim 2, the lower end portion of the pillar is fitted to the joining fitting attached to the base, and the wedge guide piece is inserted into the joint window and the wedge window hole at the lower end portion of the pillar. In the joint connection structure in the wooden building where the entire column is lowered toward the base, and the pillar and the base are joined and connected, by mounting and guiding the wedge guide piece while superposing and driving the horizontal long wedge. Wedge guide pieces d, g, j, m, o in which wedge guide grooves 11, 16, 17, 18 are dug on the inner surface and vertical concave grooves 12 are dug in the outer surface of the window holes b ', c'; A wedge guide piece d 'in which wedge guide grooves 11', 16 ', 17', 18 'are dug in the inner surface facing the wedge guide grooves 11, 16, 17, 18 and the vertical ridges 13 are formed to protrude from the outer surface. , G ′, j ′, m ′, o ′ and the vertical groove 12 to the hole edge b′1 of the wedge window hole b ′ of the joint fitting b. Then, the vertical protrusions 13 are fitted and fitted in the fitting vertical grooves 8 of the pillars, and the pair of wedge guide pieces d, d ', g, g', j, j ', m, m', Between o and o ', the driven long wedges e, i, k, n, and p are driven while being guided in the wedge guide grooves 11, 11', 16, 16 ', 17, 17', 18, 18 '. Become.

  According to the third aspect of the present invention, a pair of wedge guide pieces d, d ', g, g', j, j ', m, m' are formed in the wedge guide groove 11 formed in the inner surface facing each other. 11 ', 16, 16', 17, 17 ', the base end 9, 9' is deep, and the tip 10, 10 'is shallow. It is.

  According to the present invention, a pair of wedge guide pieces o and o ′ are provided with wedge guide grooves 18 and 18 ′ formed in the inner surface facing each other, from the base end portions 9 and 9 ′ to the distal end portion. It is the joining connection structure in the wooden building of Claim 1, 2, or 3 made into the same depth over 10, 10 '.

  In the present invention, the longitudinal concave groove 12 of one wedge guide piece d, g, j, m, o is fitted into the hole edge b'1 of the core plate 3 of the joint fitting b, and the other wedge guide piece d. Since the longitudinal protrusions 13 of ', g', j ', m', o 'are fitted in the fitting longitudinal groove 8 of the beam, girder or column, a pair of wedge guide pieces d, d', g, It is necessary that g ′, j, j ′, m, m ′, o, and o ′ have a structure in which a locking portion protrudes from one tip portion and the other tip is locked as in the prior art. Therefore, the production is easy and the production cost can be reduced. In addition, as in the prior art, the wedge guide pieces d, d ', g, g', j, j ', m, m', o, and so on as the driven horizontally long wedges e, i, k, n, and p are driven. There is no case where o ′ moves together in the driving direction and jumps outward from the wedge window hole c ′.

Further, since the driven lateral wedge e is not restricted by the wedge guide pieces d, d ', g, g', j, j ', m, m', o, o ', it is driven sufficiently. Therefore, the driven long wedges e, i, k, n, and p and the wedge guide pieces d, d'g, g ', j, j', m, m ', o, and o' are not necessarily as strict as in the prior art. Therefore, it is possible to manufacture easily and inexpensively from this point.
Further, the wedge guide pieces d, d'g, g ', j, j', m, m ', o, o' are once driven because they do not have a locking portion at the tip as in the prior art. Even if the driven long wedges e, i, k, n, and p are later loosened, it can be easily retightened by driving again, so that the beam or beam c and the column a (or the column) The connection between the base and the base can be made tight and strong as set.

A pair of wedge guide pieces d, d ', g, g', j, j ', m, m', o, o 'is driven between the pair of wedge guide pieces 8 A joining and linking structure in a wooden building in which e, i, k, n, and p are driven while being guided in the wedge guide grooves 11, 11 ', 16, 16', 17, 17 ', 18, 18'.

1st Example (FIGS. 1-7)
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. The above-described joining is achieved by driving a wooden driven horizontal wedge e between a pair of wooden wedge guide pieces d, d 'mounted in the window hole b' for wedge and the window window for wedge c at the end of the beam c. The pillar a and the beam c are tightly and firmly joined and connected via the metal fitting b, and it is most important that the laterally long wedge e is driven between the pair of wedge guide pieces d and d ′. A point.
The joining metal piece b is L-shaped with 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. The wedge window hole b ′ having a square shape 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.
The beam c has a wedge window hole c ′ having the same shape and the same size as the wedge window hole b ′, which opens on the side surfaces c4 and c5 on both sides of the end portion thereof, and the fitting vertical direction. Excavation is formed in a state of crossing the groove 8.

  The beam c has a shallow recess 7 fitted to the bottom plate 2 and a fitting vertical groove 8 fitted to the core plate 3 with respect to the joint fitting b fixedly attached to the column a, and a wedge. It is mounted and supported in a state in which the window hole for c ′ 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 is in a state where a gap f2 is left between the end surface of the bottom plate 2 of the joint fitting b. Further, the hole edge b'1 on the side farther from the pillar a of the wedge window hole b 'formed in the core plate 3 of the joint fitting b slightly protrudes into the wedge window hole c' of the beam c, on the contrary. The hole edge b'2 on the side close to the column a is positioned outside the wedge window hole c ', and the inner back portion of the fitting vertical groove 8 of the beam c and the rear end 3' of the core plate 3 A gap f3 is left in between (FIG. 2).

Next, the wedge guide pieces d and d 'and the driven long wedge e will be described.
The wedge guide pieces d and d 'have a length L substantially the same as the width of the beam c (between the side surfaces c4 and c5), and a height h that is the height of the wedge window hole b' and the wedge window hole c '. The width w is approximately half of the height h, and the corresponding position of the vertical inner surface facing each other is located at the corresponding position on the base end 9, 9 ′ side to the tip 10. , 10 ′ side, the same height (width) h ′, the base end portion 9, 9 ′ side is deep, the front end portion 10, 10 ′ side is shallow, wedge-shaped guide groove 11, 11 ′ having a concave cross section Has been established.

  Further, the wedge guide piece d has a longitudinal groove 12 formed in the center in the longitudinal direction of the outer surface, and the wedge guide piece d ′ has a longitudinal protrusion 13 protruding from the center in the longitudinal direction of the outer surface.

  As described above, the wedge guide piece d has a structure that does not have the structure corresponding to the locking portions D2 and F1 of the conventional wedge guide pieces D and F protruding from the tip thereof, and thus can be easily manufactured. It can be manufactured at a lower cost than the conventional one.

  The driven lateral wedge e has a required length that is sufficiently longer than the length L of the wedge guide pieces d, d 'and therefore also the width of the beam c, and has a square cross section with respect to its height h ″. Is substantially the same as the height (width) h 'of the wedge guide grooves 11, 11' from the base end portion 14 to the entire length of the tip end portion 15, and the width is more than the width w1 on the base end portion 14 side. It forms a tapered wooden square bar shape with a width w2 on the 15th side narrowed.

  The wedge guide pieces d and d 'and the driven laterally long wedge e are arranged such that the wedge window hole c' and the wedge window hole b are located when the beam c is mounted on and supported by the joint bracket b attached and fixed to the column a as described above. Thus, the column a and the beam c are tightly connected to each other through the joint fitting b and are firmly connected.

  For this purpose, first, the wedge guide pieces d and d 'are placed together or individually with the wedge guide grooves 11 and 11' facing each other (FIGS. 6 and 7). The longitudinal groove 12 of the wedge guide piece d is inserted into the hole b 'and slightly protrudes into the hole edge b'1 of the core plate 3 of the joint fitting b (as described above, into the wedge window hole c' of the beam c). And the vertical protrusion 13 of the wedge guide piece d 'is fitted to a position outside the wedge window hole c' in the fitting vertical groove 8 of the beam c (FIG. 2). At this time, there is a gap between the vertical protrusion 13 of the wedge guide piece d 'and the hole edge b'2 on the side of the core plate 3 of the joint fitting b on the side close to the pillar a of the wedge window hole b'. f4 becomes free.

Thereafter, the driven long wedge e is driven into the wedge guide grooves 11, 11 'from the base end portions 9, 9' of the wedge guide pieces d, d '. By this driving, the whole 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. To do.
When the pressure contact is complete, the proximal end portion 14 and the distal end portion 15 (FIG. 3) of the driven horizontal wedge e protruding outward from the side surfaces c4 and c5 of the beam c are cut and removed with a saw.

In this embodiment, the driven laterally long wedge e is driven while being guided in the wedge guide grooves 11 and 11 'of the wedge guide pieces d and d', and the beam c is passed through the wedge guide piece d 'on the side close to the column a. Since the whole is moved forward, the driven horizontally long wedge e does not bite or deform the inner surface of the wedge window hole c ′ of the beam c.
Further, the vertical concave groove 12 of the wedge guide piece d is fitted into the hole edge b'1 of the core plate 3 of the joint fitting b, and the vertical protrusion 13 of the wedge guide piece d 'is fitted to the vertical groove 13 of the beam c. 8, the wedge guide pieces d and d ′ move together in the driving direction as the driven horizontal wedge e is driven along the wedge guide grooves 11 and 11 ′. There is no possibility of jumping out of the hole c ′.

In addition, since the wedge guide pieces d and d 'do not have the equivalent to the engaging portions D2 and F1 of the conventional wedge guide pieces D and F, the driven laterally long wedge e has the wedge guide pieces d and d'. Therefore, it is not necessary to manufacture the laterally long wedge e and the wedge guide pieces d and d ′ to be as precise as in the prior art. Can be manufactured at low cost.
Furthermore, when the driven laterally long wedge e that has been once loosened later, it can be easily retightened by re-implanting.

  Therefore, the beam c and the column a can be tightly connected and firmly connected.

2nd Example (FIGS. 8-14)
This embodiment is different from the first embodiment in that the pair of wedge guide pieces and the driven horizontally long wedge are made of metal and has a different structure, but the other points are the same. Since it is the same as that of the first embodiment, common portions are denoted by the same reference numerals and description thereof is omitted, and only differences will be described below.

  The wedge guide piece g has a length L that is substantially the same as the width of the beam c (between the side surfaces c4 and c5), and a height h that is substantially the same as the height of the wedge window hole b 'and the wedge window hole c'. A rectangular parallelepiped made of metal, such as iron, having a width w of approximately one half of the height h, and having the same height (width) h ′ from the proximal end 9 side to the distal end 10 side, A wedge guide groove 11 having a concave section with a deeper portion 9 side, a shallower tip portion 10 side, and a rough inner surface is dug, and a longitudinal groove 12 is dug in the center of the outer surface in the longitudinal direction. Yes.

The wedge guide piece g ′ is a rectangular parallelepiped made of metal such as iron having the same length L, height h, and width w as the wedge guide piece g, and the distal end portion 10 ′ from the base end portion 9 ′ side. A wedge guide groove 11 'having a concave cross section with the same height (width) h', a deep base end 9 ', a shallow front end 10', and a rough inner surface is doing.
Further, a longitudinal ridge 13 is formed to protrude in the center in the longitudinal direction of the outer surface.

  The laterally long wedge i to be driven has the same length as the length L of the wedge guide pieces g and g ′, has a square cross section, and the height h ″ is the entire length from the proximal end portion 14 to the distal end portion 15. Is substantially the same as the height (width) h 'of the wedge guide grooves 11, 11', but the width w2 on the distal end portion 15 side is narrower than the width w1 on the proximal end portion 14 side, and It is in the shape of a square bar made of metal such as tapered iron with a rough surface.

  The wedge guide pieces g and g 'and the driven long wedge i are mounted on and supported by the joint fitting b fixed to the column a and the beam c is placed on the wedge window hole c' and the wedge window hole b '. In this way, the pillar a and the beam c are tightly connected to each other via the joint fitting b and are firmly joined and connected.

  For this purpose, first, the wedge guide pieces g and g 'are placed together or individually with the wedge guide grooves 11 and 11' facing each other (FIGS. 13 and 14). The longitudinal groove 12 of the wedge guide piece g is inserted into the hole b ′ and slightly protrudes into the hole edge b′1 of the core plate 3 of the joint fitting b (as described above, into the wedge window hole c ′ of the beam c). And the vertical protrusion 13 of the wedge guide piece g ′ is fitted to the position of the fitting vertical groove 8 of the beam c outside the wedge window hole c ′ (FIG. 8). At this time, there is a gap between the vertical protrusion 13 of the wedge guide piece g ′ and the hole edge b′2 on the side close to the column a of the wedge window hole b ′ of the core plate 3 of the joint fitting b. f4 becomes free.

Thereafter, the driven laterally long wedge i is driven into the wedge guide grooves 11, 11 ′ from the base end portions 9, 9 ′ of the wedge guide pieces g, g ′. By this driving, the whole 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. To do.
When the pressure contact is complete, the base end portion 14 has its end face flush with the end faces of the base ends 9, 9 'of the wedge guide pieces g, g', and therefore also the side face c4 of the beam c. In addition, each related part is designed (FIG. 9).

Also in this embodiment, as in the first embodiment, the driven horizontally long wedge i is driven while being guided by the wedge guide grooves 11 and 11 'of the wedge guide pieces g and g', and the wedge closer to the pillar a is placed. The entire beam c is moved forward through the guide piece g ′.
Therefore, the driven long wedge i does not bite or deform the inner surface of the wedge window hole c ′ of the beam c.

  Further, the vertical concave groove 12 of the wedge guide piece g is fitted into the hole edge b′1 of the core plate 3 of the joint metal b, and the vertical protrusion 13 of the wedge guide piece g ′ is fitted to the fitting vertical groove 8 of the beam c. The wedge guide pieces g and g 'move together in the driving direction as the driven horizontal wedge i is driven along the wedge guide grooves 11 and 11', so that the wedge window hole There is no such thing as jumping out of c '.

Therefore, the connection connection between the beam c and the column a can be tightly and firmly connected as set. In particular, since the inner surfaces of the wedge guide grooves 11, 11 'of the wedge guide pieces g, g' and the peripheral surface of the driven long wedge i are roughened, the frictional resistance of the wedge is large, and the wooden building vibrates due to an earthquake or the like. There is no risk of inadvertent relaxation even if it happens.
Further, the wedge guide pieces d and d 'do not have the equivalent to the engaging portions D2 and F1 of the conventional wedge guide pieces D and F, and the driven long wedge i is a wedge guide piece g, g'. Therefore, in the case where the driven horizontally long wedge i is later loosened, the driving can be easily retightened by driving again.

FIGS. 15 and 16 show a first modification of the wedge guide pieces g and g ′ and the driven horizontally long wedge i in the second embodiment.
The wedge guide pieces j and j 'according to this modification are configured so that the wedge guide grooves 16 and 16' formed on the inner surface of the ratchet have a cross-section> and <shape. , G ′ wedge guide grooves 11, 11 ′ are different from the concave cross section, and the driven horizontal wedge k according to this modified example has a rhombus cross section. Unlike the wedge guide pieces g, g ′ and the driven horizontal wedge i of the second embodiment, the driven horizontal wedge i is different from the horizontal wedge i of FIG.
Therefore, description of the same structural portion is omitted, and only the same reference numerals are given.

FIGS. 17 and 18 show a second modification of the wedge guide pieces g and g ′ and the driven horizontally long wedge i in the second embodiment.
The wedge guide pieces m and m 'according to this modification have a semicircular outer peripheral surface and wedge guide grooves 17 and 17' formed on the inner surface of the wedge guide pieces m and m 'in the second embodiment. The wedge guide pieces g and g 'have a rectangular outer peripheral surface and the wedge guide grooves 11 and 11' have a concave shape. Further, the driven laterally long wedge n according to this modified example has a laterally elliptical cross section. Is different from the driven lateral wedge i of the second embodiment in that it has a square cross section, and the other points are different from the wedge guide pieces g and g 'of the second embodiment and the driven lateral wedge i. Absent.
Therefore, description of the same structural portion is omitted, and only the same reference numerals are given.

  In adopting the wedge guide pieces m, m 'and the driven long wedge n according to the second modification, the shape of the wedge window hole b' of the joint fitting b and the wedge window hole c 'of the beam c are used. The shape of the wedge window hole b 'is made circular so as to match the outer peripheral surface of the wedge guide pieces m and m' so that the accommodation of the horns fits.

FIGS. 19 and 20 show a third modification of the wedge guide pieces g and g ′ and the driven horizontally long wedge i in the second embodiment.
The wedge guide pieces o and o 'according to this modification have the same length L as the wedge guide pieces g and g' of the second embodiment, and the height h is the wedge window hole b 'and the wedge window. It is substantially the same as the height of the hole c ′ and is a rectangular parallelepiped made of metal such as iron having a width w of approximately one half of the height h, and the wedge guide piece o is a longitudinally concave groove in the center in the longitudinal direction of the outer surface. 12 is dug, and the wedge guide piece o ′ has a longitudinal protrusion 13 protruding from the center in the longitudinal direction of the outer surface, which is the same as the wedge guide pieces g and g ′ of the second embodiment.

  The wedge guide pieces o, o ′ according to this modification are different from the wedge guide pieces g, g ′ of the second embodiment, and the wedge guide grooves 18, 18 ′ formed on the inner surface of the wedge guide pieces, The difference is that the depths are dug and formed over the entire length up to the portion 10, but the other points are the same as the wedge guide pieces g and g 'of the second embodiment.

  Further, the driven lateral wedge p according to this modification has the same length and height as the length of the driven lateral wedge i of the second embodiment, but the width w3 is the same over the entire length, and the tip part is slightly It forms a metal square bar shape such as iron with 15 edges chamfered.
