Description

  The present invention relates to a joining bracket set, a joining structure of a structural frame of a wooden building using the joining bracket set, a wooden building having such a joining structure of a structural casing, and the like.

2. Description of the Related Art Conventionally, in order to connect and fix a structural frame of a wooden building, it has been practiced to arrange a joint fitting on the joint surface of the structural frame.
Patent documents 1 and 2 are shown as literatures which disclosed such a junction structure. Patent Document 1 discloses a joining structure in which a T-shaped fitting 13 as a joining fitting is arranged on a beam 11 as a structural casing in order to connect a tube column 12 as a structural casing. Further, for example, Patent Document 2 discloses a joining structure in which a joining fitting in which the fitting pieces 11 are assembled is arranged on a base 25 serving as a structural casing in order to connect a pipe column 26 as the structural casing. In the joining structure using the joining metal fittings as in these Patent Documents 1 and 2, the structural housing can be joined with a joining strength different from that in the structure not using the joining fitting.
By the way, since a metal stretches and deforms with respect to an increasing tensile force and then breaks beyond an allowable stress, the greater the elongation rate, the greater the stress with respect to the tensile force (higher tensile performance). Therefore, it is expected that the joining metal fitting used for the structural housing also has a high elongation rate. As such a joining metal fitting having a large elongation rate, for example, a rod-like metal fitting such as a bolt can be cited. Since the bolt can be configured to be long with respect to the cross-sectional area, the elongation rate can be increased. Patent document 3 is shown as an example using a volt | bolt. Patent Document 3 discloses a joining structure of a structural frame of a wooden building using a long bolt (long bolt 13). In Patent Document 3, a screw part 11 is screwed into a pillar 1, a hollow hole 13 c is formed in the screw part 11, and a long bolt 13 is inserted into the hollow hole 13 c via a joint fitting 14 fixed to the foundation 3. 11 and the tip of the long bolt 13 are screwed together. With such a joint structure, the elongation rate with respect to the tensile force of the long bolt 13 is large, so that a structure with excellent tensile strength can be realized.

JP 2000-64426 A JP 2003-56075 A JP 2007-77611 A

As one of the reasons for using the screw portion 11 together with the long bolt 13 as in Patent Document 3, even if the long bolt 13 is screwed directly to the structural housing, it will be removed from the structural housing in the first place when the pulling force is applied. This is because the long bolt 13 falls off. For this reason, in Patent Document 3, the screw portion 11 is screwed into the pillar 1 as a structural housing and is firmly fixed to the foundation 3 via the joint fitting 14, and the long bolt 13 is pulled with the pillar 1 fixed to the foundation 3 to the last. A configuration is adopted in which the force (pull-out force) is mainly applied to the long bolt 13.
However, there are some problems in the configuration as in Patent Document 3. For example,
1) By forming the hollow hole 13c along the longitudinal direction of the screw part 11, the screw part 11 becomes thin, and when the bending load or the compressive load is applied to the wooden building, the strength is considered to decrease. It is done.
2) Even if the pillar 1 is fixed by screwing the screw part 11 into the pillar 1, the pillar 1 is pulled out of the screw part 11 due to a strong pulling force (pull-out force), and the extension of the long bolt 13 cannot be expected. There is a case.
3) The processing operation of forming the hollow hole 13c along the longitudinal direction of the screw portion 11 and forming the female screw at the bottom thereof is troublesome and requires skill.
Therefore, the joint structure of the structural frame of a wooden building using a metal bar-shaped metal fitting formed with a male screw part that solves the problems 1) to 3) or the junction structure of such a structural frame is used. There was a need for a wooden structure.

In order to achieve the above object, as means 1, there is provided a joint fitting set used for connecting and fixing a first structural housing and a second structural housing of a wooden building, the first structural housing. And a metal rod-like metal fitting having a male screw portion formed on the outer periphery disposed between the second structural housing, the plate-shaped main body, and a base end portion of the main body or the vicinity of the base end portion. Embedded in the second structural body having a rod-shaped bracket guide passage disposed over and a female screw portion screwed with the male screw portion formed on the inner wall surface of the rod-shaped bracket guide passage. A connecting fitting disposed, and the rod-like fitting is inserted into the rod-like fitting guide passage of the connecting fitting, and the male screw portion is screwed onto the female screw portion in the fitted state. It was to so.
Further, as means 2, there is a joining metal fitting set used for connecting and fixing the first structural housing and the second structural housing of the wooden building, wherein the first structural housing and the second structure are used. A metal rod-shaped metal fitting having a male screw portion formed on the outer periphery disposed between the housing, a female screw member screwed to the male screw portion, a plate-like main body, and a base end portion of the main body Alternatively, the second member having a rod-shaped metal fitting guide passage disposed from the vicinity of the base end portion to the inside and a window hole formed in the main body facing the opening end on the inner side of the rod-like metal fitting guide passage. Connecting rods that are embedded in the structure housing, and the rod-like fittings are fitted into the rod-like fitting guide passages of the coupling fittings and exposed from the window holes in the fitted state. The female screw member is used by being screwed to the male screw portion.
In the case of such a joining metal fitting, when the first structural housing and the second structural housing are connected and fixed by connecting (combining) the rod-shaped metal fittings to the connecting metal fittings, the first structural housing and the second structure. Even if a large tensile force is generated between the casing and the casing, the extension of the rod-shaped bracket can be allowed while the rod-shaped bracket is supported by the connecting bracket, and the pulling performance of the structural casing can be improved. Further, since both the connecting metal fittings and the rod-like metal fittings can be arranged embedded in the structural housing, they are not viewed from the side in the construction state.
The difference between the means 1 and the means 2 is a means for fixing the rod-shaped metal fitting to the joining metal fitting. In the means 1, the male threaded portion of the rod-shaped metal fitting is screwed into the female screw portion formed on the inner wall surface of the shape guide part, Then, since the male threaded portion of the bar-shaped metal fitting is exposed to the window hole from the bar-shaped metal fitting guide passage, a female screw member is screwed to the exposed male screw part and tightened.

Here, the “first (second) structural frame” is a portion corresponding to a framework (member constituting the frame) when building a wooden building, for example, a foundation, a wall, a pillar, a horizontal member ( Widely refers to beams, girders, etc.), foundations, purlins, etc. In addition, it is also possible to use laminated wood, for example, an orthogonal laminated board called CLT (Cross Laminated Timber).
In addition, the “metal rod-shaped metal fitting” is a connection metal fitting that is stretched by receiving a tensile force and applying a force greater than stress, and the external shape is not particularly limited as long as a male screw portion is formed on the outer periphery. . For example, even if a so-called head-shaped bolt shape is encountered, a completely long cylindrical shape without a head, or a male threaded portion formed over the entire length, actually a rod-shaped bracket guide passage or female thread The male screw part may be formed only in the part screwed with the member. Moreover, the cross-sectional shape of the part in which the male screw part is not formed may not be circular.
The “main body” of the connecting metal fitting is preferably composed of surfaces whose front and back sides are parallel to each other, and is preferably constructed in a plate shape so as not to reduce the strength of the xylem. Moreover, the bending strength in a connection part also improves by setting it as plate shape.
The “bar-shaped bracket guide passage” is arranged from the base end portion of the main body or from the vicinity of the base end to the inside, and has a shape as a linear passage that can guide the inserted bar-shaped bracket guide passage in the longitudinal direction. It only has to be presented. Therefore, for example, it may be configured in a cylindrical shape or not in a cylindrical shape. As a case where it is not cylindrical, for example, opposing long plates may be arranged. Further, for example, a ring portion through which the rod-shaped metal fitting is inserted only in the base end portion or the vicinity of the base end portion and the inward side (portion near the tip end) may be provided.
Moreover, it is preferable that the cylindrical metal fitting guide passage is arranged along the surface direction of the main body (that is, the advancing direction of the main body). In that case, for example, a cylindrical rod-shaped metal fitting guide passage may be placed on the surface of the main body, and for example, a long plate facing the main surface of the main body may be disposed. Further, for example, the rod-shaped metal fitting guide passage may be sandwiched in a groove formed along the surface direction of the main body.
Examples of the “female screw member” include a nut member. The shape of the female screw member is not limited as long as it can be screwed with the male screw portion of the rod-shaped metal fitting.
The explanation of the above phrase is the same in the following means.

Further, as means 3, it is a joint metal fitting set used for connecting and fixing a structural frame of a wooden building installed on a foundation to the foundation side, and is a plate-like shape arranged in an embedded form in the structural frame And a base-like metal guide passage which is disposed along the surface of the main body and has an open end which opens to the back surface of the base portion and which is disposed inward of the main body. A column base bracket fixed on the foundation, the column base bracket having a male screw portion screwed with the male screw portion formed on the inner wall surface of the rod-shaped bracket guide passage, the column base bracket and the A metal rod-shaped metal fitting having a male screw portion formed on the outer periphery disposed over the structural housing, and the rod-shaped metal fitting is inserted into the rod-shaped metal fitting guide passage of the main body, and the male fitting is inserted in the inserted state. The screw part is used by being screwed onto the female screw part.
Further, as means 4, it is a joining metal fitting set used for connecting and fixing a structural frame of a wooden building installed on a foundation to the foundation side, and is a plate shape arranged in an embedded form in the structural frame A base portion on which the main body is erected, a first opening end that is disposed along the surface direction of the main body and opens on the back surface of the base portion, and a second opening that opens on the inner side of the main body A column base bracket fixed on the foundation, the rod base bracket having an end, a window hole formed in the main body facing the second opening end, and the column base bracket And a metal bar-shaped metal fitting having a male screw portion formed on the outer periphery disposed over the structural housing, and a female screw member screwed to the male screw part, the bar-shaped metal fitting being the bar shape of the main body The male inserted into the metal fitting guide passage and exposed from the window hole in the inserted state. The female screw member is to be used by being screwed against di unit.
With these joint fittings, when a rod-shaped bracket is connected to (combined with) a column base bracket and the structural frame is connected and fixed, even if a large tensile force is generated between the column base bracket and the structural frame, The extension of the rod-like metal fitting can be allowed while the rod-like metal fitting is supported by the main body, and the pulling performance of the structural housing can be improved. Moreover, since a plate-shaped main body can be arrange | positioned in the embedded form in a structure housing, it is not visually recognized from a side surface direction in a construction state.
Here, the “base part” of the column base bracket is a member on which the main body is erected, and may be installed on the foundation itself, and has a connecting part with the foundation in the lower area of the base part. May be.

Further, as the means 5, a through hole for engaging a fixed pin is formed in the main body.
As a result, when the main body is embedded in the structural housing, the main body can be fixed to the structural housing through this through hole, and even if a strong pulling force (extraction force) is applied, the main body is firmly It will be held by the structural housing.
As the means 6, the rod-shaped metal fitting is a bolt member having a head portion.
As a result, it is possible to easily and reliably fix and hold the bar-shaped metal fitting in the bar-shaped metal guide passage.
Further, as the means 7, the rod-shaped metal fitting is a bolt member in which the lug screw portion is formed with a lag screw portion and a male screw portion is formed near the tip.
If it is such a rod-shaped metal fitting itself, it will be screwed into the structure housing by the lag screw part, and the proof stress of the whole structure with respect to strong pulling force (pull-out force) will improve.

Further, as the means 8, in the joining structure of the structural frame of the wooden building in which the first structural frame and the second structural frame are connected and fixed using the connection metal, the connection metal is provided on the outer periphery as the connection metal. A bar-shaped metal fitting having a threaded portion, a plate-like main body, a bar-shaped metal fitting guide passage disposed from the base end portion of the main body or the vicinity of the base end to the inside, and an inner wall surface of the bar-like metal fitting guide passage And a connecting metal fitting having a female screw part to be screwed with the formed male screw part, the rod-like metal fitting penetrating through the first structural housing to the second structural housing side. The connecting part is inserted into a slit formed in an end surface of the second structural body facing the first structural body, and protrudes in the direction of the second structural body. The bar-shaped metal fittings arranged in the bar-shaped metal fitting guide passage Is the male threaded portion is so screwed with said female screw portion formed in a rod shape metal fitting guide passage.
With such a joining structure of the structural housing, when the first structural housing and the second structural housing are connected and fixed by connecting (combining) the rod-shaped metal fittings to the connecting metal fitting, the first structural housing and the second structural housing are connected. Even if a large pulling force is generated between the structure housing and the rod, the extension of the rod-shaped bracket can be allowed while the rod-shaped bracket is supported by the connecting bracket, and the pulling performance of the structure frame can be improved. Further, since both the connecting metal fittings and the rod-like metal fittings are arranged embedded in the structural housing, they are not viewed from the side in the construction state.
Further, as the means 9, the rod-shaped metal fitting is screwed into the female screw portion only near the tip.
That is, the portion that is not near the tip of the rod-shaped metal fitting in the fixed state is held in a free state without being screwed with the female screw portion. For this reason, the portion that is not close to the tip (except for the portion that is fixed between the first structural housing and the second structural housing) becomes a portion that extends when a large tensile force is applied, improving the tensile performance of the structural housing. I will let you.

Further, as the means 10, in the joining structure of the structural frame of the wooden building in which the first structural frame and the second structural frame are connected and fixed using the connection metal, the connection metal is at least near the tip. A rod-shaped metal fitting having a male screw portion formed on the outer periphery thereof, a female screw member that can be screwed with the male screw portion of the rod-shaped metal fitting, a plate-like main body, and a base end portion of the main body or the vicinity of the base end portion A bar-shaped metal fitting guide passage disposed inward, and a connecting metal fitting having a window hole formed in the main body facing the opening end on the inner side of the bar-shaped metal guide passage, The metal fitting is fixed so as to penetrate the first structural housing so that the male screw portion extends to the second structural housing, and the connecting metal fitting faces the first structural housing of the second structural housing. Inserted into the slit formed in the end face, The bar-shaped bracket projecting in the direction of the structural housing 2 is disposed in the bar-shaped bracket guide passage, the tip end is exposed from the window hole, the female screw member and the male screw portion are screwed together, and the female screw The member is fastened to the open end of the bar-shaped metal fitting guide passage.
With such a joining structure of the structural housing, when the first structural housing and the second structural housing are connected and fixed by connecting (combining) the rod-shaped metal fittings to the connecting metal fitting, the first structural housing and the second structural housing are connected. Even if a large pulling force is generated between the structure housing and the rod, the extension of the rod-shaped bracket can be allowed while the rod-shaped bracket is supported by the connecting bracket, and the pulling performance of the structure frame can be improved. In particular, the female screw member is screwed near the tip of the rod-shaped metal fitting in a fixed state and tightens the rod-shaped metal fitting, so that the portion not near the tip of the rod-shaped metal fitting is held in a free state. For this reason, the portion that is not close to the tip (except for the portion that is fixed between the first structural housing and the second structural housing) becomes a portion that extends when a large tensile force is applied, improving the tensile performance of the structural housing. I will let you. Further, since both the connecting metal fittings and the rod-like metal fittings are arranged embedded in the structural housing, they are not viewed from the side in the construction state.

Further, as the means 11, the rod-shaped metal fitting cannot be detached in the direction of the second structural housing by the head part integrally formed on the upper part thereof or the female screw member screwed with the male screw formed on the upper part thereof. It was held.
As a result, it is possible to easily and reliably fix and hold the bar-shaped metal fitting in the bar-shaped metal guide passage.
Further, as the means 12, the rod-shaped metal fitting is inserted into a through hole formed in advance in the first structural housing.
If it does in this way, it will become easy to arrange | position a rod-shaped metal fitting inside a 1st structure housing.
Further, as the means 13, the rod-shaped metal fitting is a bolt member in which a lag screw portion is formed and a male screw portion is formed near the tip.
If it is such a rod-shaped metal fitting itself, it will be screwed into the structure housing by the lag screw part, and the proof stress of the whole structure with respect to strong pulling force (pull-out force) will improve.
Further, as the means 14, the connecting metal fitting is formed with a first through hole communicating with the front and back, and the second structural housing is formed with a second through hole intersecting with the slit and collated with each other. In the verification state, a pin member is driven into the first and second through holes.
As a result, the connecting fitting is fixed by the pin member in a state where it is embedded in the structural casing, and even if a strong pulling force is applied, the connecting fitting is firmly held by the structural casing.

Further, as means 15, in a joint structure of a structural frame of a wooden building in which a foundation and a structural frame are connected and fixed using a connection metal, a rod-shaped metal fitting having a male screw portion formed on the outer periphery as the connection metal A base portion on which a plate-like main body is erected, a bar-shaped metal fitting guide passage having an opening end opened on the back surface of the base portion and arranged inward of the main body, and A column base bracket fixed on the foundation having a female screw portion screwed with the male screw portion formed on an inner wall surface, and the rod-shaped metal fitting on the base body side on the structure housing side The main body is inserted into a slit formed on an end surface of the structural housing facing the column base bracket, and the rod bracket is inserted into the rod bracket guide passage. Arranged inside said male screw There was as screwed with the female threaded portion formed on the rod-shaped fitting guide passage.
With these joint fittings, when a rod-shaped bracket is connected to (combined with) a column base bracket and the structural frame is connected and fixed, even if a large tensile force is generated between the column base bracket and the structural frame, The extension of the rod-like metal fitting can be allowed while the rod-like metal fitting is supported by the main body, and the pulling performance of the structural housing can be improved. In addition, since the plate-like main body is disposed in an embedded state in the structural housing, it is not visually observed from the side direction in the construction state.

Further, as means 16, in the joint structure of the structural frame of the wooden building in which the foundation and the structural frame are connected and fixed using the connection bracket, a male screw part is formed at least on the outer periphery near the tip as the connection bracket. A bar-shaped metal fitting, a female screw member that can be screwed into the male screw portion of the bar-shaped metal fitting, a base portion on which a plate-like main body is erected, and a first opening end that opens on the back surface of the base portion Fixed on the foundation having a rod-shaped metal fitting guide passage having a second opening end opened to the inner side of the main body and a window hole formed in the main body facing the second opening end A column base bracket, wherein the rod-shaped bracket is erected and fixed to the base portion so that the male screw portion extends to the structure housing side, and the body is the column base bracket of the structure housing Inserted into the slit formed on the end face facing The rod-shaped metal fitting is disposed in the rod-shaped metal fitting guide passage, the tip end is exposed from the window hole, the female screw member and the male screw portion are screwed together, and the female screw member is used for the rod-like metal fitting guide. It was made to clamp | tighten with respect to the said opening end of a channel | path.
With these joint fittings, when a rod-shaped bracket is connected to (combined with) a column base bracket and the structural frame is connected and fixed, even if a large tensile force is generated between the column base bracket and the structural frame, The extension of the rod-like metal fitting can be allowed while the rod-like metal fitting is supported by the main body, and the pulling performance of the structural housing can be improved. In particular, the female screw member is screwed near the tip of the rod-shaped metal fitting in a fixed state and tightens the rod-shaped metal fitting, so that the portion not near the tip of the rod-shaped metal fitting is held in a free state. For this reason, the portion that is not close to the tip (except for the portion fixed to the column base bracket) becomes a portion that extends when a large pulling force is applied, and the pulling performance of the structural frame is improved. In addition, since the plate-like main body is disposed in an embedded state in the structural housing, it is not visually observed from the side direction in the construction state.

As the means 17, the column base metal fitting is fixed to the foundation by an anchor member.
As a result, the column base bracket can be firmly fixed to the foundation.
Further, as the means 18, the main body is formed with a first through hole communicating with the front and back, and the structural housing is formed with a second through hole intersecting with the slit and collated with each other. Thus, a pin member is driven into the first and second through holes.

Hereinafter, a joining structure of a structural body of a wooden building using a joining bracket set and a joining bracket set according to an embodiment of the present invention will be described with reference to the drawings.
(Embodiment 1)
FIGS. 1A to 1C show a connection plate 1 made of an iron-based alloy as a connection fitting constituting a joining bracket set. The connecting plate 1 includes a rectangular main body 2, and a passage pipe 3 serving as a rod-shaped metal fitting guide passage extending in the longitudinal direction is disposed at the center of the main body 2 in the width direction. As an example, in the present embodiment, the main body 2 is configured to have a width of 150 mm and a length of 300 mm. The cylindrical passage tube 3 is fitted in a slit 4 formed inward from one short side to the center in the width direction of the main body 2 and fixed by welding. In the drawing, the trace of welding (so-called bead) is omitted.
In the present embodiment, the slit 4 is formed to have a length of about 3/4 of the entire length of the main body 2, and the passage pipe 3 has a uniform amount of protrusion in the front and back directions in the slit 4, that is, the passage pipe 3. The diameter position is fixed so as to be arranged at the center in the thickness direction of the main body 2. By fixing the passage tube 3 in this way, the longitudinal direction of the passage tube 3 extends in parallel to the surface direction of the main body 2. The opening 3 a on the proximal end side of the passage pipe 3 is arranged at a position that exactly coincides with the short side of the main body 2. The passage tube 3 has a small diameter portion 5 having a small diameter near the tip (inward side), and a female screw portion 5 a is formed on the inner wall surface of the small diameter portion 5. As shown in FIGS. 13A to 13C, the passage pipe 3 is drawn until the tip of the round steel pipe has a predetermined diameter, and the narrowed portion becomes the small diameter portion 5. The internal thread portion 5a is formed by processing the inner wall of the small diameter portion 5 with an internal thread processing tool such as a tap (not shown).
A plurality of metal fitting side through holes 6 for drift pins are formed in two left and right regions sandwiching the passage tube 3 near the tip of the main body 2. In the present embodiment, three metal fitting side through holes 6 are formed on each of the left and right sides, and are arranged in series at equal intervals along the longitudinal direction of the main body 2.

A joining structure using such a connecting plate 1 will be described with reference to FIGS.
In the present embodiment, a case where a floor panel F as a first structural frame of a wooden building and a wall panel W as a second structural frame are connected and fixed will be described as an example. In the present embodiment, as an example, the floor panel F uses a CLT panel having a seven-layer structure as appropriate, and the wall panel W uses a CLT panel having a five-layer structure as appropriate. The floor panel F is arranged so that the length and width directions are horizontal (that is, the thickness direction is vertical), and is sandwiched in the vertical direction by the wall panel W whose length and width directions are vertical. To be built. The floor panel F is formed with perforations 9 communicating with each other in the vertical direction. The wall panel W is formed with a pair of left and right slits 10 on the end face to which the floor panel F is joined. The thickness, width and depth of the internal space of the slit 10 are configured to be the same size as the thickness, width and length of the connecting plate 1. Moreover, the wood part side through-hole 12 is formed in the position which corresponds with the metal fitting side through hole 6 formed in the connection plate 1 so that the slit 10 may be crossed. The wood part side through hole 12 is formed over the front and back surfaces of the wall panel W. In the present embodiment, as an example of the joining structure, a case where one wall panel W is connected and fixed to a lower position of the floor panel F will be described with reference to the drawings.

  As shown in FIGS. 2 (a) to 2 (c) and FIG. 3, the connecting plate 1 is combined with a hexagonal bolt 7 as a rod-shaped metal fitting and used as a joint metal fitting set. The hexagon bolt 7 is composed of a hexagonal column-shaped head 7a and a long cylindrical body 7b. The male threaded portion 7c is formed only on the outer circumference of about 1/5 of the entire length of the main body 7b near the tip of the main body 7b. The outer diameter of the main body 7 b is configured to be slightly smaller than the inner diameter of the passage tube 3, and the male screw portion 7 c can be screwed with the female screw portion 5 a of the passage tube 3.

In connecting and fixing the floor panel F and the wall panel W, as shown in FIG. 2A, the operator first inserts the hexagon bolt 7 into the perforation 9 from the top side through the washer 11 from above the floor panel F. The main body 7b of the dropping hexagon bolt 7 is inserted vertically. In the state where the hexagon bolt 7 is suspended from the head 7a, the lower half side of the main body 7b including the male screw portion 7c protrudes below the floor panel F. In this state, the connecting plate 1 is made to approach the hexagon bolt 7 from the lower side of the floor panel F, and the hexagon bolt 7 is caused to enter the passage pipe 3 from the opening 3 a on the base end side of the passage pipe 3. As a result of the entry, the male screw portion 7c near the tip of the hexagon bolt 7 reaches the female screw portion 5a at the tip of the passage tube 3 (at the back). The two female screws 5a are relatively rotated so that the female screw 5a is screwed together.

The connecting plate 1 that has entered the left and right slits 10 in a state where the upper end of the wall panel W is in contact with the back surface of the floor panel F can be accurately stored without a gap. And since the metal fitting side through-hole 6 and the wood part side through-hole 12 are collated in this approach state, the drift pin 13 is finally attached to both through-holes 6 and 12 as shown in FIG. Driving from the side (or the back side), the connecting and fixing work of the floor panel F and the wall panel W is completed. Here, the example in which the wall panel W is connected to the lower side of the floor panel F has been described, but the wall panel W can also be connected to the upper side of the floor panel F by arranging the connecting plate 1 on the upper side. Further, if the connecting plate 1 and the hexagon bolt 7 are oriented (that is, the direction of the connection fitting set) by alternately arranging the protruding direction of the connecting plate 1 on the lower side and the upper side, the wall panel W is connected vertically with the floor panel F interposed therebetween. It is also possible to do.
In addition, although the construction example which arranged the hexagon bolt 7 on the floor panel F side first and constructed | assembled in order of the connection plate 1 and the wall panel W after that was given in FIG. 3, the following construction may be sufficient.

The connecting plate 21 includes a main body 22 having the same thickness, width and length as the main body 2 of the connecting plate 1. At the center in the width direction of the main body 22, a passage pipe 23 is disposed as a rod-shaped bracket guide passage extending in the longitudinal direction. The cylindrical passage tube 23 is fitted into a slit 24 formed inward from one short side to the center in the width direction of the main body 22 and fixed by welding. In the drawing, the trace of welding (so-called bead) is omitted. In the present embodiment, the slit 24 is formed to have a length that is about half of the entire length of the main body 2, and the passage tube 23 is fixed in the slit 24 so that the amount of protrusion in the front and back direction is uniform. A window hole 25 communicating with the front and back connected to the slit 24 is formed at the center position of the main body 22. The opening 23a on the proximal end side of the passage tube 3 is disposed at a position that exactly coincides with the short side of the main body 22, and the distal end portion is disposed so as to slightly protrude from the slit 24 into the window hole 25. As shown in FIG. 4 (c), unlike the passage pipe 3 of the first embodiment, the passage pipe 23 is formed of a cylinder having a uniform thickness without forming the female screw portion 5a therein.
A plurality of metal fitting side through holes 26 for drift pins are formed in two left and right regions sandwiching the window hole 25 near the tip of the main body 22. In the present embodiment, three metal-side through holes 26 are formed on each of the left and right sides, and are arranged in series at equal intervals along the longitudinal direction of the main body 2.

A joining structure using such a connecting plate 21 will be described with reference to FIGS. As in the first embodiment, a case where one wall panel W is connected and fixed to a lower position of the floor panel F will be described with reference to the drawings.
As shown in FIGS. 5 (a) to 5 (c) and FIG. 6, the connecting plate 21 is combined with a hexagonal bolt 27 as a rod-shaped metal fitting and a nut 28 as a female screw member and used as a joining metal fitting set. The hexagon bolt 27 is composed of a hexagonal columnar head 27a and a long cylindrical body 27b. A lag screw portion 27c is formed on the outer periphery of about 2/5 of the entire length of the main body 27b near the head 27a of the main body 27b. The male screw portion 27d is formed only on the outer periphery of about 1/5 of the entire length of the main body 27b near the tip of the main body 27b. The outer diameter of the main body 27 b is configured to be slightly smaller than the inner diameter of the passage pipe 23. The lag screw portion 27 c is configured to have a slightly larger diameter than the perforations 9 of the floor panel F. The nut 28 can be screwed with the male screw portion 27 d of the hexagon bolt 27.

In connecting and fixing the floor panel F and the wall panel W, as shown in FIG. 5A, the operator first inserts the hexagon bolt 27 into the perforation 9 from the top side of the floor panel F through the washer 29 through the washer 29. Drop it. Then, since the lag screw portion 27c is larger than the diameter of the perforation 9, the hexagon bolt 27 is held by the lag screw portion 27c and is temporarily stopped. Here, the operator uses a tool (not shown) to lower the lag screw portion 27c while biting into the inner wall surface of the perforation 9 so that the lower half side of the main body 27b including the male screw portion 27d protrudes below the floor panel F. To. Next, in this state, as shown in FIG. 5B, the connecting plate 21 is made to approach the hexagon bolt 27 from the lower side of the floor panel F and enter from the opening 23a on the proximal end side of the passage pipe 23 (FIG. 5B). 5 (b) state). As a result of the entry, the male screw portion 27d near the tip of the hexagon bolt 27 is exposed from the tip of the passage tube 3 into the window hole 25, and the nut 28 is screwed to the male screw portion 27d via the washer 30. By tightening the nut 28 so as to thrust move in the direction of the passage pipe 3, the connecting plate 21 is firmly fixed to the back surface of the floor panel F by the tightening action of the screw.
Next, the wall panel W is approached from below as shown in FIG. 5C with respect to the floor panel F to which the connection plate 21 is fixed to the back surface in this way, and the connection plate 1 is inserted into the slit 10 at the upper end of the wall panel W. To enter. The connecting plate 1 that has entered the left and right slits 10 in a state where the upper end of the wall panel W is in contact with the back surface of the floor panel F can be accurately stored without a gap. And since the metal fitting side through-hole 26 and the wood part side through-hole 12 are collated in this approach state, the drift pin 13 is finally attached to both the through-holes 26 and 12 from the front side of the wall panel W similarly to Embodiment 1. Driving and fixing the connection between the floor panel F and the wall panel W is completed. Similarly to the first embodiment, the wall panel W can be connected to the upper side of the floor panel F by arranging the connecting plate 1 on the upper side. Moreover, it is also possible to connect the wall panel W up and down across the floor panel F.

(Embodiment 3)
Next, the column base metal 31 of Embodiment 3 will be described.
FIGS. 8A and 8B show an iron-based column base metal 31 as a connection metal that constitutes the joint metal set. The column base bracket 31 includes an upper plate 32 as a base portion, a lower plate 33 disposed below the upper plate 32 disposed in parallel to the upper plate 32, and between the upper plate 32 and the lower plate 33. Are provided with a box portion 35 composed of five identically-shaped leg plates 34 arranged at equal intervals. The leg plates 34 are joined to the upper plate 32 and the lower plate 33 by welding at the upper and lower positions. As an example, in the present embodiment, the box portion 35 is configured to have a front-rear width of 90 mm, a left-right width of 600 mm, and a height of 105 mm. In the drawing, the trace of welding (so-called bead) is omitted. In the four spaces surrounded by the five leg plates 34 arranged at equal intervals, the upper plate 32 and the lower plate 33, the upper plate 32 and the lower plate 33 arranged in the space closest to the left and right respectively A first communication hole 36 and a second communication hole 37 that are communicated vertically are formed. The positions of the first communication hole 36 and the second communication hole 37 coincide with each other in the vertical direction (that is, in plan view).

On the upper plate 32, a pair of left and right rectangular bodies 38 are fixed upright by welding. As an example, in the present embodiment, the main body 38 is configured to have a width of 150 mm and a length (height) of 300 mm. The pair of main bodies 38 are arranged at the center position in the width direction of the upper plate 32 so that the longitudinal direction of the upper plate 32 is the width direction. A passage pipe 39 serving as a rod-shaped bracket guide passage extending in the longitudinal direction is disposed at the center in the width direction of each main body 38. A cylindrical passage tube 39 is fitted in a slit 40 formed inward from the short side on the upper plate 32 side in the center in the width direction of the main body 38 and fixed by welding. In the drawing, the trace of welding (so-called bead) is omitted.
In this embodiment, the slit 40 is formed to have a length that is about 3/4 of the entire length of the main body 2, and the passage tube 39 has a uniform amount of protrusion in the front and back directions in the slit 40, that is, the passage tube 39. The diameter position is fixed so as to be arranged at the center in the thickness direction of the main body 38. By fixing the passage tube 39 in this way, the longitudinal direction of the passage tube 39 extends in parallel to the surface direction of the main body 38.
As shown in FIG. 8B, the passage pipe 39 is arranged so as to collate with the first communication hole 36 formed in the upper plate 32. The passage tube 39 is a small diameter portion 42 having a small diameter near the tip (upper side), and an internal thread portion 42 a is formed on the inner wall surface of the small diameter portion 42. The passage tube 39 is formed with a small diameter portion 42 and a female screw portion 42a as in the first embodiment (that is, in the steps shown in FIGS. 13A to 13C).
A plurality of metal fitting side through holes 43 for drift pins are formed in two left and right regions sandwiching the small diameter portion 42 near the tip of the main body 38. In the present embodiment, three metal-side through holes 43 are formed on each of the left and right sides, and are arranged in series at equal intervals along the longitudinal direction (vertical direction) of the main body 38.

A joining structure using such a column base bracket 31 will be described with reference to FIGS.
In the present embodiment, a case where the wall panel W of a wooden building is connected and fixed to the foundation B using the column base bracket 31 will be described as an example. In the present embodiment, as an example of the wall panel W, a CLT panel having a five-layer structure is cut and used as appropriate. The wall panel W is constructed such that the length and the width direction are perpendicular to the surface direction of the foundation B. The wall panel W has the same shape as that used in the first and second embodiments, and the slit 10 is used at a position that is vertically inverted from the first and second embodiments.
In the third embodiment, the column base bracket 31 is used in combination with the same hexagon bolt 7 as in the first embodiment as a joining bracket set.
First, the hexagon bolt 7 is inserted into the passage tube 39 of the column base metal 31 from the tip side. For this purpose, as shown in FIG. 9A, the operator places the column base bracket 31 with the washer 11 on the lower side of the upper plate 32 of the box portion 35, and in that state, the hexagon bolt from the lower position of the lower plate 33. The second communication hole 37 is inserted with the tip of 7 facing upward. That is, since the distance between the upper plate 32 and the lower plate 33 is shorter than the length of the hexagon bolt 7, the hexagon bolt 7 cannot be inserted into the passage tube 39 from between the upper plate 32 and the lower plate 33. The hexagon bolt 7 that has passed through the second communication hole 37 is allowed to enter the main body 7b into the passage pipe 39 from the first communication hole 36 as it is. As a result of the entry, the male screw portion 7c near the tip of the hexagon bolt 7 reaches the female screw portion 42a at the upper end (near back) of the passage tube 39. The two female screws 42a are relatively rotated so that the female screw portion 42a is screwed together, and the hexagon bolt 7 is moved upward to tighten the head 7a together with the washer 11 so that it firmly contacts the lower surface of the upper plate 32. .

Next, as shown in FIG. 9B, the column base bracket 31 on which the hexagon bolts 7 are arranged is fixed on the foundation B. Since the two anchor bolts A corresponding to the left and right second communication holes 37 are erected at the position where the column base bracket 31 is installed, the operator can install the anchor bolts A in the second communication holes 37. Lead to be inserted into. Then, the nut 45 is screwed onto the anchor bolt A via the washer 44, and the nut 45 is thrust-moved in the direction of the foundation B to be tightened to fix the column base bracket 31 on the foundation B.
Next, as shown in FIG. 9C, the wall panel W is installed on the upper plate 32 (on the box portion 35) of the column base metal 31 so that the main body 38 is accommodated in the slit 10. Since the metal fitting side through hole 43 and the wood part side through hole 12 are collated in a state where the main body 38 is accommodated in the slit 10, the drift pin 13 is finally attached to both the through holes 43 and 12 similarly to the first embodiment. Driving in from the front side of the panel W, the connecting and fixing work of the floor panel F and the wall panel W is completed.

The following effects are produced by the embodiment as described above.
(1) In the first to third embodiments, the connecting plate 1 (21) or the main body 38 is inserted into the drift pin 13 which is a separate member and fixed to the wall panel W. The connecting plate 1 (21) or the main body 38 and the wall panel W can be integrated, and when a strong tensile force acts between the floor panel F and the wall panel W, the hexagon bolt 7 (27) can elastically extend. A structure with excellent tensile strength can be realized.
(2) The connecting plate 1 (21) or the main body 38 has passage pipes 3, 23, 39, which are portions where hexagon bolts 7 (27) are fitted and force is transmitted to the hexagon bolts 7 (27). The periphery is firmly fixed by welding by the connecting plate 1 (21) or the main body 38, and the passage pipes 3, 23, 39 have very high strength against external force (tensile, compression, bending).
(3) Since the hexagon bolt 27 is firmly biting into the floor panel F by the lag screw portion 27c, the tensile strength is superior to the case where the hexagon bolt 7 without the lag screw portion is used for the floor panel F.

The above embodiments are merely described as specific embodiments for illustrating the principle of the present invention and the concept thereof. That is, the present invention is not limited to the above embodiment. The present invention can also be embodied in the following modified form, for example.
In the above embodiment, only the partial joining of the structural frame of the wooden building has been described. However, for example, it is possible to construct an entire multi-story wooden building with such a joining structure. The structural material may also be applied to other than the floor panel F and the wall panel W as described above, and the structural material may be wood other than CLT. Moreover, although it demonstrated as an example about connecting between the floor panel F and the wall panel W and between the wall panel W and the column base metal fitting 31 in the above, for example, the wall panel W and the wall panel W are connected in a horizontal direction. You may make it apply to.
In Embodiments 1 and 2, the wall panel W is connected after the connection plate 1 (21) is fixed to the floor panel F side with the hexagon bolt 7 (27). However, such an order is an example. For example, in the first embodiment, even if the connecting plate 1 is inserted into the slit 10 of the wall panel W first, it is screwed with the hexagon bolt 7 later. Also good.
In the above embodiment, the hexagon bolt 27 having the lag screw portion 27c is used in the second embodiment. However, the hexagon bolt 27 may be combined with the connecting plate 1 as in the first embodiment. Conversely, the hexagon bolt 7 of the first embodiment may be combined with the second embodiment. In short, the rod-shaped metal fitting can be appropriately changed and combined with the coupling metal fitting.
In the third embodiment, before the column base metal 31 is fixed on the foundation B, the hexagon bolt 7 is screwed in the passage pipe 39 first. However, even after the column base bracket 31 is fixed on the foundation B, if the hexagon bolt 7 can be screwed to the passage pipe 39, the hexagon bolt 7 is fixed to the passage pipe 39 after fixing on the foundation B. May be screwed. For example, there is a sufficient gap between the upper plate 32 and the lower plate 33 such that the hexagon bolt 7 cannot be used, or the positions of the communication hole 36 and the second communication hole 37 coincide with each other. This is because such a construction is possible if it is not aligned, or if the hexagon bolt 7 is not so long.

In the first and second embodiments described above, when the wall panel W is connected up and down with the floor panel F interposed therebetween, the combination of the hexagon bolt 7 (27) and the connection plate 1 (21) is used as a joint fitting set. This is made possible by reversing the vertical positions of the hexagon bolt 7 (27) and the connecting plate 1 (21) for each set. However, even if the vertical direction of the joining bracket set is not inverted upside down for each adjacent joining bracket set, a single bar-shaped bracket is used as shown in FIGS. It is also possible to connect the panels W.
First, as shown in FIG. 11, a bolt member 47 is prepared as a rod-shaped metal fitting in which male screws 46 are formed on both side ends of the floor panel F. The bolt member 47 has male screw portions 48 formed at both ends. A grip portion 49 chamfered in a hexagonal shape is formed at a position slightly above the center of the bolt member 47 (a length corresponding to the thickness of the floor panel F). The maximum diameter of the grip portion 49 (the line segment connecting the opposite vertices of the hexagon) is configured to be larger than the perforations 9 formed in the floor panel F.
About the joining structure which connects the wall panel W up and down through the floor panel F by using such a bolt member 47 and the connecting plates 1 and 21 used in the first and second embodiments as a connection fitting set. explain.
As shown in FIG. 11, a pair of left and right bolt members 47 are dropped into the perforations 9 of the floor panel F from above. The dropped bolt member 47 is temporarily held by the grip portion 49 without falling off the floor panel F. Then, similarly to the first embodiment, the respective bolt members 47 are advanced into the passage pipe 3 of the connecting plate 1 and the male screw portion 48 formed at the lower end of the bolt member 47 and the female screw portion 5a inside the passage pipe 3 are connected. Screw together. Then, the lower wall panel W is suspended using the drift pins 13 (the connection work of the wall panel W may be performed after the connection fitting set is attached).
Next, as shown in FIG. 12, the connecting plate 21 of the second embodiment is attached to the bolt member 47 that stands up above the floor panel F, and is tightened with the nut 28 via the washer 30. The upper wall panel W is installed on the floor panel F and fixed using the drift pin 13.
If it does in this way, it will become possible to connect the wall panel W to the upper and lower sides of the one bolt member 47 via the connection plates 1 and 21, respectively. Since the upper connecting plate 21 (which may be upside down) is tightened with a nut 28, the female screw portion 5 a inside the passage tube 3 of the lower connecting plate 1 fixed earlier and the male lower end of the bolt member 47. The screwing relationship with the screw portion 48 is not loosened.
In addition, in FIG. 11, although the bolt member 47 was previously arrange | positioned at the floor panel F side and the construction example which constructs in order of the connection plate 1 and the wall panel W after that was given, the following construction may be sufficient.
1) First, the connecting plate 1 is embedded in the slit 10 at the upper end of the wall panel W (at this stage, the drift pin 13 may or may not be driven).
2) The floor panel F is installed on the upper end surface of the wall panel W (it may be considered that the upper end surface of the wall panel W is disposed below the floor panel F).
3) Next, the bolt member 47 is inserted through the perforation 9 of the floor panel F from above the floor panel F and screwed into the female screw portion 5a inside the connection plate 1 passage tube 3 in the wall panel W.

The shape of the connecting plate 1 (21) and the column base metal 31 is only an example in the above embodiment, and may be implemented in other forms. For example, the length of the passage pipe 3 of the connecting plate 1 may be changed, the position of the opening 3a of the passage pipe 3 may be shifted, or the position of the passage pipe 3 may be shifted at the center in the width direction. The shape of the main body 2 may be any shape other than a rectangle. Further, a plurality of connecting plates 1 may be arranged in parallel with the main body 2. Further, for example, it is possible to change the number of main bodies 38 erected on the column base metal 31 or change the shape of the box portion 35.
-For example, the passage pipe 3 of the connecting plate 1 as a rod-shaped metal fitting guide passage does not necessarily have to be a long unbroken cylinder. In short, it is only necessary to guide so that a rod-like metal fitting such as the inserted hexagon bolt 7 (27) can be fixed to the connecting plate 1 side near the tip. For example, there may be a configuration in which there is a cut in the middle of the passage tube 3, and for example, as shown in FIG. 14, a slit 53 is formed in the main body 52 of the connecting plate 51, and a bar-shaped metal fitting guide portion is formed at the base of the slit 53. 54 (here, a semicircular metal fitting may be formed in a ring shape) is fixed by welding, and corresponds to the small diameter portion 5 and the female screw portion 5a of the first embodiment at the back of the slit 53. The female screw member 55 may be fixed. That is, there may be a configuration in which there is no member that guides between the bar-shaped metal fitting guide portion 54 and the female screw member 55.
Further, as shown in FIG. 15, only the female screw member 55 forms a slit 56 and is fixed to the main body 52, and serves as a rod-shaped fitting guide passage for guiding the rod-shaped fitting to the female screw member 55 toward the female screw member 55. A pair of guide wall surfaces 57 may be fixed to the main body 52 by welding. The wall surface 57 is arranged in parallel with a width that allows a rod-shaped metal fitting such as the hexagon bolt 7 (27) to pass through a rectangular plate.

The components of the above-described embodiments and modifications may be arbitrarily selected and combined. In addition, any component of each embodiment or modification, and any component described in the means for solving the invention or any component described in the means for solving the invention And may be combined arbitrarily.
