Description

The present invention relates to a wooden member, a manufacturing method thereof, and a building frame.

In wooden buildings using the wooden frame construction method, the wooden members that form the columns, beams, foundations, wall materials, etc. are joined together using fittings such as drift pins and lag screw bolts, and the members are tightly tied together. The rigidity and strength of the joints have been increased to improve earthquake resistance. Possible measures to increase the rigidity of the joint include increasing the number of drift pins, etc., and increasing the diameter of the drift pins, etc. However, when trying to increase the rigidity of the joint by these measures, splitting occurs in the surrounding wood members, for example, at the edge of the wood member, starting from a drift pin, etc. that is applied in the axial direction of the wood member. There are issues that may arise.

Therefore, various techniques have been proposed to deal with such splitting. For example, Patent Document 1 proposes a wooden member in which the edge of a wooden column is reinforced with a metal ring. More specifically, as a joining fitting for joining the end face of the lower end of the column to the base, a pin is inserted into a pin hole formed through the lower end of the column in a direction perpendicular to the axial direction of the column. , a metal pipe-shaped tenon member that is connected to the lower end and also to the base, and a metal ring that is fitted around the lower end of the column are integrally connected by the bottom plate. The joint fitting is a wooden member that is fitted into the edge of the pillar.

On the other hand, Patent Document 2 proposes a wooden member in which a pre-cut hole is provided at the edge of the wooden member and a pipe is inserted into the hole. More specifically, a hole is first drilled in the end or side of the wood that is the structural material, a connector is inserted into this hole, the adhesive is injected from the injection port using a syringe with a nozzle, and the adhesive is discharged from the discharge port. Then, finish injecting the adhesive, integrate the wood and connector, and embed a splitting prevention ring in the end of the wood on the side where part of the connector is protruding so as to cover part of the outer circumference of the connector. It is a wooden member in which structural members are joined together with connecting metal fittings, etc. via connectors to prevent splitting.

Japanese Patent Application Publication No. 11-338968 JP2011-94422A

In the wooden member described in Patent Document 1, since the metal ring surrounds the wooden member from the edge to the side surface, the metal ring is exposed on the side surface of the wooden member, which impairs the appearance and design of the wooden member. There is a risk of damage. Further, in the wooden member described in Patent Document 2, since precision is required for pre-cutting holes, processing requires time and effort.

The present invention has been made in view of the above-mentioned problems, and provides a wooden member that prevents splitting of the edge surface by a simple method and does not impair the appearance design, a manufacturing method thereof, and a building equipped with this wooden member. The purpose is to provide a framework.

In order to achieve the above object, one aspect of the wooden member according to the present invention is as follows:
A fixing member is buried from the edge of the wooden member to the inside.
A reinforcing member, which is an endless standing piece and has a corrugated blade at one end, is embedded around the fixing member on the edge surface.

According to this aspect, in a configuration in which the fixing member is buried from the edge face to the inside of the wooden member, the reinforcement is provided around the fixing member on the edge face with an endless standing piece having a corrugated blade at one end. By embedding the component, the reinforcing component is driven or press-fitted into the edge surface through the corrugated blade, making manufacturing (processing) easy without the need for pre-cutting holes, etc., and converting the fixed component into a wooden component. Splitting that may occur when axial force is applied can be effectively suppressed. Furthermore, since the reinforcing member is buried only in the edge face, the reinforcing member is not exposed on the side surface of the wooden member, and there is no risk that the appearance and design of the wooden member will be impaired.

Further, by embedding the reinforcing member in the edge surface of the wooden member, the reinforcing member can suppress medium- to long-term drying shrinkage of the wooden member.

Here, the reinforcing member may be a member made of hard resin, etc. in addition to a metal member, and is not damaged when being driven into the edge surface of the wood member, and is It suffices if it has enough rigidity to provide splitting resistance. Furthermore, examples of the fixing member buried in the edge surface of the wooden member include a lag screw bolt (LSB).

Further, other aspects of the wooden member according to the present invention include:
A plurality of the fixing members are embedded in the wooden member,
The reinforcing member is embedded around the plurality of fixing members.

According to this aspect, since the reinforcing member is buried around the plurality of fixing members in the wooden member, it becomes easy to split due to the plurality of fixing members being buried, and the plurality of fixing members Although complex splitting that connects members is likely to occur, it is possible to effectively suppress such splitting. Furthermore, since the wooden member is provided with a plurality of fixing members on its end face, the wooden member can be incorporated into the building frame with high bonding strength without causing splitting of the wooden member.

Further, other aspects of the wooden member according to the present invention include:
The reinforcing member is characterized in that the shortest distance between the reinforcing member and the edge of the fore surface of the wooden member is 20 mm.

According to this aspect, since the shortest distance between the reinforcing member and the edge of the edge surface of the wooden member is 20 mm (having such a dimension), the edge of the edge edge of the wooden member It is possible to suppress splitting in as large a range as possible inside the facet while suppressing splitting in the area. According to the present inventors, it has been determined that when the shortest distance between the reinforcing member and the edge of the edge of the wood member is less than 20 mm, splitting is likely to occur at the edge of the edge of the wood member. Therefore, based on this identification result, in this aspect, the shortest distance between the reinforcing member and the edge of the edge surface of the wooden member is set to 20 mm.

Further, other aspects of the wooden member according to the present invention include:
When the diameter of the fixing member is d, the distance between adjacent fixing members is set to 4d or more.

According to this aspect, when the diameter of the fixing member is d, by ensuring a distance of 4 d or more between adjacent fixing members, each fixing member can be fixed without being influenced by other adjacent fixing members. While ensuring sufficient joint strength by the members, it is possible to prevent splitting at the end face by the reinforcing member surrounding these fixing members.

Further, other aspects of the wooden member according to the present invention include:
The reinforcing member is made of metal and has a circular shape in plan view.

According to this aspect, since the reinforcing member is made of metal and has a circular shape in plan view, the reinforcing member is rigid and as thin as possible to effectively prevent splitting of the end face of the wooden member. Can be done. In particular, since the reinforcing member is circular in plan view, the force acting from the fixing member inside the reinforcing member on the end face of the wooden member (splitting on the end face) is stronger than when the reinforcing member is a polygon including a rectangular shape in plan view. The circular reinforcing member is difficult to deform in response to the force that tends to cause this, and the restraining force against the edge surface of the wooden member increases against this force that acts from the inside. For example, in the case of a rectangular shape in plan view, although the corners are strong, the middle of each side is easily deformed, so the counterforce against the force acting from the inside is relatively weak, and the effect of suppressing splitting is lower in the case of a circular shape in plan view. It will be lower than that.

Moreover, in another aspect of the wooden member according to the present invention,
The other end of the standing piece is provided with a flange perpendicular to the standing piece,
The fixing member is inserted into an insertion hole formed in the flange, and the inner surface of the insertion hole is in contact with the outer surface of the fixing member.

According to this aspect, a flange is provided at the other end of the standing piece of the reinforcing member, and the fixing member is inserted into the insertion hole opened in the flange, and the inner surface of the insertion hole and the outer surface of the fixing member are in contact with each other. As a result, the shear strength area that resists the shear force acting in the direction perpendicular to the fixing member can be increased by the area of the flange, and the shear strength of the fixing member can be increased. If the reinforcing member does not have a flange, the shear opposing area will be only the cross-sectional area of the fixed member. If the fixed member is, for example, a shaft-shaped fixed member, the shear opposing area is small, so it is difficult to expect a large shear strength, and the fixed member It becomes necessary to increase the shear strength by increasing the diameter of the steel.

Moreover, one aspect of the building frame according to the present invention is
It is characterized in that the wooden member is included as at least one of a beam, a column, and a wall material.

According to this aspect, by having the wooden member of the present invention as at least one of the beam, column, and wall material, splitting of the edge surface is prevented, and therefore the strength of the joint where the members are joined is high. It becomes the building frame.

An example of a building frame is a building frame in which the end face of a wooden beam, which is a wooden member, is reinforced with a reinforcing member, and the wooden beam and the wooden column are joined by a fixing member buried in both. Can be mentioned. Another example is a building frame in which the end face of a wooden pillar is reinforced with a reinforcing member, and a fixing member embedded in the wooden pillar is buried in the foundation or indirectly joined via a joining metal fitting or the like. Furthermore, there is a building frame in which the edge side of the wall material made of wood panels is reinforced with a reinforcing member, and the wall material and the wood beam are provided with a joint part where the wall material and the wood beam are joined by a fixing member embedded in both.

Further, one aspect of the method for manufacturing a wooden member according to the present invention is as follows:
A reinforcing member, which is an endless standing piece and has a corrugated blade at one end of the standing piece, is embedded by driving or press-fitting around the groove opening through which the fixing member is inserted on the edge face of the wooden member,
The fixing member is embedded through the groove opening in the edge surface of the wooden member.

According to this aspect, after driving or press-fitting the reinforcing member, which is an endless standing piece and has a corrugated blade at one end, around the groove opening through which the fixing member is inserted on the edge surface of the wooden member, By embedding the fixing member through the groove opening in the surface, the reinforcing member can be efficiently and easily installed on the edge surface of the wooden member without the need for pre-cutting holes or the like. Further, since the reinforcing member is embedded in the edge surface of the wooden member by driving or press-fitting, the reinforcing member can be firmly fixed to the surrounding wooden member. Here, the manufacturing method of this aspect may be performed in a factory or in a manufacturing yard at a building construction site.

As can be understood from the above explanation, according to the wooden member, its manufacturing method, and building frame of the present invention, splitting of the edge surface can be prevented by a simple method, and the wooden member and its manufacturing method do not impair the appearance design. A manufacturing method and a building frame including this wooden member can be provided.

Hereinafter, an example of a wooden member, a manufacturing method thereof, and a building frame according to an embodiment will be described with reference to the accompanying drawings. Note that in this specification and the drawings, substantially the same constituent elements may be given the same reference numerals to omit redundant explanation.

[Wood member, manufacturing method thereof, and building frame according to embodiment]
An example of a wooden member, a manufacturing method thereof, and a building frame according to an embodiment will be described with reference to FIGS. 1 to 10. Here, both FIGS. 1 and 2 are perspective views of an example of a reinforcing member applied to the edge surface of the wooden member according to the embodiment. Moreover, FIG. 3 is a perspective view of an example of the wooden member according to the embodiment, viewed from the edge side, and also shows splits in which the occurrence of splitting is suppressed.

The reinforcing member 10 shown in FIG. 1 is a member that is disposed around a fixing member that is buried from the edge of the wooden member to the inside, and is installed on the edge of the wooden member. The reinforcing member 10 is a metal member including an endless (circular in plan view in the illustrated example) standing piece 11 .

Of the two ends of the standing piece 11, one end 12 is provided with a corrugated blade 13 continuous in the circumferential direction, and the other end 15 is a flat surface. Here, in the illustrated waveform blade 13, all blades have the same height, but the waveform blade has blades with a plurality of heights (two or more types), and the tip of each blade. The line connecting the two may not be flat, but may have irregularities. In the case of a wave-shaped blade having blades at a plurality of heights, the wave-shaped blade can more easily penetrate into the edge surface of the wooden member.

When installing the reinforcing member 10 on the edge surface of a wooden member, the corrugated blade 13 is brought into contact with the edge surface, and the flat other end 15 is driven in with a striking tool such as a hammer, so that the reinforcing member 10 is attached to the edge surface. Buried. Here, the reinforcing member 10 may be installed on the edge surface of the wooden member by press-fitting or the like instead of driving.

In this way, since the reinforcing member 10 is installed on the edge surface of the wooden member by driving or press-fitting, it has the rigidity (strength) that can withstand the impact force at the time of installation and can exert the effect of suppressing splitting at the end of the wooden member. In addition to the metal member, a hard resin member or the like may be used as long as it has the following.

On the other hand, the reinforcing member 10A shown in FIG. 2 has a flange 16 provided at the other end 15 of the reinforcing member 10. Here, the endless standing piece 11 and the flange 16 may be integrally formed as a whole, or the flange 16 may be connected to the other end 15 of the standing piece 11 by welding, adhesive, or the like.

An insertion hole 17 is provided at the center of the flange 16, into which a shaft-shaped fixing member 30 (see FIG. 3) is inserted.

FIG. 3 shows a state in which the reinforcing member 10A shown in FIG. 2 is embedded in the edge surface 21 of the wooden member 20.

The wooden member 20 is made of solid wood or laminated wood with laminated laminae. It is. In addition to the illustrated shaft-like members, the wooden members include structural plywood, laminated timber (a material made by fixing multiple pieces of lumber with adhesive, screws, etc.), CLT (Cross Laminated Timber) panels, etc. The wall material may be made of wood panels.

A shaft-shaped groove 22 in which a lag screw bolt 30 (an example of a fixing member) is embedded is bored from the small end face 21 of the wooden member 20 to the inside, and an injection hole that communicates with the groove 22 from one side of the wooden member 20 is bored. Holes 23 are further drilled. Here, in addition to the illustrated example of the lag screw bolt 30, the fixing member may include a pipe plug screw bolt (pipe LSB), a tenon pipe (including a form in which a drift pin is inserted into the hole of the tenon pipe), etc. It may be.

The reinforcing member 10A is embedded in the edge surface 21 with the insertion hole 17 in the center of the flange 16 of the reinforcing member 10A aligned with the groove 22.

The lag screw bolt 30 is inserted into the groove 22 through the insertion hole 17, and the adhesive 25 injected through the injection hole 23 is filled between the groove 22 and the lag screw bolt 30, resulting in GIR (Glued in). Rod) is joined. Here, the inner surface of the insertion hole 17 and the outer surface of the lag screw bolt 30 are in contact with each other.

In the wooden member 20, the reinforcing member 10A is arranged on the small end face 21 so as to surround the lag screw bolt 30, and the endless standing piece 11 surrounds the lag screw bolt 30 inside the wooden member 20. do. Due to the configuration in which the endless standing piece 11, which is circular in plan view, surrounds the lag screw bolt 30, splitting as shown in the illustrated example may occur when an axial force is applied from the lag screw bolt 30 to the wooden member 20. C can be effectively suppressed.

In particular, since the reinforcing member 10A has a circular shape in plan view, the force acting from the fixing member 30 on the inside of the reinforcing member 10A on the edge surface 21 of the wooden member 20 is greater than when the reinforcing member 10A has a polygonal shape including a rectangular shape in plan view. The circular reinforcing member 10A is difficult to deform against (the force that tends to cause splitting C on the edge surface 21), and the restraining force on the edge surface 21 of the wooden member 20 resists this force acting from the inside. growing.

In addition, the lag screw bolt 30 is inserted into the insertion hole 17 formed in the flange 16, and the inner surface of the insertion hole 17 and the outer surface of the lag screw bolt 30 are in contact with each other, so that the lag screw bolt 30 is perpendicular to the lag screw bolt 30. The shear strength area that resists the shear force S acting in the direction can be increased by the area A2 of the flange 16, and the shear strength of the lag screw bolt 30 can be increased. If there is no flange 16, the shear bearing area will be only the cross-sectional area A1 of the lag screw bolt 30, and in order to increase the shear bearing area of the axial lag screw bolt 30, the diameter of the lag screw bolt 30 must be increased. Therefore, it becomes necessary to increase the shear strength.

Moreover, since the reinforcing member 10A is embedded in the edge surface 21 of the wooden member 20 by driving or press-fitting, the reinforcing member 10A is firmly fixed to the surrounding wooden member 20. Therefore, the strength of the end portion including the face 21 of the wooden member 20 can be increased without increasing the cross section of the wooden member 20.

Further, by embedding the reinforcing member 10A in the edge surface 21 of the wooden member 20, medium- to long-term drying shrinkage of the wooden member 20 can be suppressed.

Furthermore, in the wooden member 20, since the reinforcing member 10A is buried only in the edge face 21, the reinforcing member 10A is not exposed on the side surface of the wooden member 20, and there is a possibility that the appearance design of the wooden member 20 may be impaired. do not have.

Next, an example of a method for manufacturing a wooden member according to an embodiment will be described with reference to FIGS. 4A and 4B. Here, FIGS. 4A and 4B are process diagrams of an example of a method for manufacturing a wooden member according to an embodiment.

First, as shown in FIG. 4A, a wooden member 20 is prepared in which a shaft-shaped groove 22 is drilled from the fore face 21 to the inside, and the groove opening 22a exposed on the fore face 21 and the insertion hole in the center of the flange 16 are prepared. 17, the corrugated blade 13 of the standing piece 11 is brought into contact with the edge face 21, and then the standing piece 11 is buried inside the wooden member 20 in the X1 direction by driving or press-fitting.

Next, as shown in FIG. 4B, the lag screw bolt 30 is inserted into the groove 22 in the X2 direction through the insertion hole 17 and the groove opening 22a, and the adhesive is injected into the groove 22 in the X3 direction through the injection hole 23. By doing so, the lag screw bolt 30 is GIR-bonded to the wooden member 20.

According to the illustrated manufacturing method, the reinforcing member 10A is driven or press-fitted into the edge surface 21 through the corrugated blade 13 at one end 12 of the endless standing piece 11 of the reinforcing member 10A, so that the reinforcing member is installed. There is no need to perform processing such as pre-cutting holes on the edge surface 21 for this purpose, and the manufacturing (processing) properties of the wooden member 20, including the installation of the fixing member 30, are extremely good.

As described above, in the example shown in FIGS. 1 to 4, one fixing member 30 is embedded in the edge surface 21 of the wooden member 20, and the reinforcing members 10, 10A are placed around the fixing member 30 so as to surround the one fixing member 30. Refer to FIGS. 5 to 7 below for a configuration in which a plurality of fixing members 30 are buried in the edge surface 21 of the wooden member 20 and a reinforcing member surrounds the plurality of fixing members 30. and explain.

First, with reference to FIG. 5, the manner in which the wood member 20 is split on the edge surface 21 will be described for each manner in which the fixing member 30 is embedded. Here, FIG. 5(a) is a diagram showing an example of splitting mode at the edge surface when one fixing member is located at the center position of the edge surface of the wooden member, and FIG. FIG. 5(c) is a diagram showing an example of splitting mode on the edge surface when there are two fixing members on the edge surface of the wooden member, and FIG. It is a figure which shows an example of the split aspect in.

As shown in FIG. 5(a), in a configuration having one fixing member 30, a split C extending from the fixing member 30 to the end sides 21a of the left and right (or top and bottom) fore faces 21 as shown in the example shown in FIG. is likely to occur. Here, the diameter of the fixing member 30 is d, and the length of the split C between the fixing member 30 and the edge 21a is t1.

On the other hand, as shown in FIG. 5(b), in a configuration having two fixing members 30, in addition to a split C having a length t3 that connects the two fixing members 30, each fixing member 30 A split C having a length t2 extending from the edge to the edge 21a of the fore surface 21 may occur.

Compared to the form shown in FIG. 5(a), since the distance between each fixing member 30 and the end side 21a is shorter, splitting C having a length t2 corresponding to this distance is likely to occur.

Note that the distance t3 between the fixing members 30 is set to 4d or more, which is four times the diameter d of the fixing members 30, so that each fixing member 30 is not affected by other adjacent fixing members 30. sufficient bonding strength can be ensured. Therefore, the length of the split C that occurs so as to connect the fixing members 30 to each other corresponds to the distance t3.

On the other hand, as shown in FIG. 5(c), in a configuration in which four fixing members 30 are provided so as to be located at each corner of a square or rhombus in plan view, splitting which connects each fixing member 30 is possible. A split C may occur that connects each fixing member 30 and the adjacent edge 21a. That is, compared to FIGS. 5A and 5B, as the number of fixing members 30 increases, complicated splitting C is more likely to occur.

As a measure to suppress the occurrence of splitting C shown in FIG. 5(a), as already explained, reinforcing members 10 and 10A are buried in the edge surface 21 so as to surround the fixing member 30.

In contrast, measures for suppressing the occurrence of splitting C shown in FIGS. 5(b) and 5(c) will be described with reference to FIG. 6. Here, FIG. 6(a) is a diagram showing a mode in which a reinforcing member is buried in contrast to FIG. 5(b), and FIG. 6(b) is a diagram showing a mode in which a reinforcing member is buried in contrast to FIG. It is a figure showing the mode where it is buried.

As shown in FIG. 6(a), in a configuration having two fixing members 30, a reinforcing member 10 is embedded around them. Here, the shortest distance t4 between the reinforcing member 10 and the edge 21a of the edge surface 21 is set to 20 mm. This 20 mm is based on a specific result by the present inventors that when the shortest distance between the reinforcing member 10 and the edge 21a is less than 20 mm, splitting that connects the reinforcing member 10 and the edge 21a is likely to occur. .

On the other hand, by making the planar dimension of the reinforcing member 10 as large as possible, splitting can be suppressed in the widest possible range inside the face 21, so the reinforcing member has dimensions such that the shortest distance is 20 mm. By applying No. 10, an extremely high splitting suppression effect can be expected.

Further, as shown in FIG. 6(b), even in a configuration having four fixing members 30, the reinforcing member 10 is buried in the edge face 21 so as to surround the four fixing members 30, and the reinforcing member 10 It is preferable to set the shortest distance t4 between the end side 21a and the end side 21a to 20 mm.

Here, as shown in FIG. 7, as a reinforcing member surrounding the plurality of fixing members 30, a flange 16 is provided with a plurality of (four in the illustrated example) insertion holes 17 through which each of the fixing members 30 is inserted. By applying the reinforcing member 10B, in addition to the above-mentioned splitting suppressing effect, the shear strength of the fixing member 30 can be increased by the flange 16, as described above, which is preferable.

Next, a plurality of examples of building frames according to the embodiment will be described with reference to FIGS. 8 to 10. Here, FIGS. 8A and 8B are enlarged longitudinal cross-sectional views of an example of a joint between a wooden beam and a wooden column in the building frame according to the embodiment, and FIGS. 9A and 9B are longitudinal cross-sectional views according to the embodiment.

In the wooden beam 20B, one end of the lag screw bolt 30 inserted into the groove 22 is fixed to a fixture 40, and the lag screw bolt 30 is GIR-bonded using the adhesive 25 filled in the groove 22.

On the other hand, one end of the lag screw bolt 30 inserted into the groove 22 penetrating the opposing side surface of the wooden column 20A is also fixed to the fixing metal fitting 40, and similarly GIR bonded using the adhesive 25 filled in the groove 22.

Further, as shown in FIG. 8B, in a configuration in which two lag screw bolts 30 are fixed to each fixing fitting 40, a reinforcing member 10 is disposed so as to surround the two lag screw bolts 30, and a wooden beam It is buried in 20B.

Further, as shown in FIG. 9A, at the joint between the wooden pillar 20A and the foundation 50 that constitute the building frame 60, a hollow fixing fitting 40A is buried at the end of the wooden column 20A, and the fixing fitting 40A is buried at the end of the wooden column 20A. The reinforcing member 10 is arranged on the outer side (lower side) of the structure. In the wooden pillar 20A, one end of the tenon pipe 35 is fixed to the fixing metal fitting 40A, and each of the drift pins 36 is inserted into the mutually orthogonal through holes 35a of the tenon pipe 35, so that the tenon pipe 35 is fixed to the wooden pillar 20A. Fixed to.

On the other hand, the head of an anchor bolt buried in the base 50 is fixed to the fixing metal fitting 40A.

In addition, as shown in FIG. 9B, in the case where two tenon pipes 35 are fixed to each fixing metal fitting 40A, the reinforcing member 10 is disposed so as to surround the two tenon pipes 35, and the wooden pillar 20A will be buried in

Here, a tenon pipe 35 and a drift pin 36 as shown in FIGS. 9A and 9B may be applied as a connection form between the wooden column 20A and the wooden beam 20B shown in FIGS. 8A and 8B, or a tenon pipe 35 and a drift pin 36 as shown in FIGS. A GIR joint using a lag screw bolt 30 as shown in FIGS. 8A and 8B may be applied as a joining form between the wooden column 20A and the base 50 shown in FIG. 9B.

As shown in FIG. 10, the joint part of the wooden member whose end face 21 is made split-proof by the reinforcing members 10 and 10A described above includes the column base part 61, the rigid frame joint part 62, and the load-bearing wall. It can be applied to various joint parts, such as the diagonal end part 63 of the diagonal member that constitutes the diagonal member, the truss joint part 64, etc.
