Description

The present invention relates to a proof stress-imparting panel member that is suitably used for construction, remodeling, reinforcement, etc. of a wooden frame building.

Wooden frame buildings have many merits such as warmth and humidity control, excellent heat insulation, low environmental load, human-friendly, high degree of freedom in floor plans, and easy expansion / renovation and remodeling. In order to obtain the earthquake resistance of such a wooden frame building, a bearing wall has been conventionally used. The load-bearing wall is composed of braces and load-bearing surface materials after the amount and arrangement of the load-bearing wall are calculated.

In order to improve workability, a load-bearing panel in which a load-bearing wall is made into a panel has been proposed as disclosed in Patent Document 1 below. This load-bearing panel is provided with a horizontal reinforcing portion and a vertical reinforcing portion inside the outer peripheral frame, and these reinforcing portions have a thickness equivalent to the thickness of the wire members constituting the framework of the wooden frame building. It is composed of a horizontal axis member or a vertical axis member and a face material held between these and the outer peripheral frame.

A bearing panel with such a configuration is very effective in that it can form a bearing wall with high bearing capacity simply by fitting it into the framework, has good workability, and can be constructed in a short period of time without skilled workers. ..

Japanese Patent No. 6484752

However, the load-bearing panel of Patent Document 1 is formed in the size of a wall and is large. In addition, as described above, the bearing wall must be arranged in advance, so that it is somewhat inconvenient when performing extension / renovation, remodeling, or reinforcement.

So far, there is no panel member that can be used as one member smaller than the wall for forming a bearing wall.

The present invention provides a load-bearing panel member that can be used for construction of wooden framed buildings, extension / renovation, remodeling, reinforcement of existing buildings, manufacturing of wall panels, etc. The main purpose is to be able to promote the use of wooden framed buildings that have the advantages of.

The means for that is a panel member attached to the shaft material of a wooden frame building, which is fixed to a core plate portion made of a square plate material and four side edges on both the front and back surfaces of the core plate portion. The shaft member is composed of a edging portion made of a square lumber that sandwiches the core plate portion, and the end surface of the outer periphery of the core plate portion is formed on two parallel sides of the load-bearing panel member that is flush with the outer peripheral surface of the edging portion. It is a panel member with a shaft to which the side surfaces of the shaft member having a cross section corresponding to the cross section are joined .

In this configuration, the edging portion made of square lumber sandwiches and hardens the four sides, which are the entire circumference of the core plate portion made of plate material, from both the front and back sides, and keeps the entire core plate portion flat. The end faces of the four sides of the core plate portion and the outer peripheral surface of the edging portion flush with these are flat, so that the positional deviation between the core plate portion and the edging portion is prevented. The load-bearing panel member is in contact with the side surface of the shaft material of the wooden frame building, restrains the contacted shaft materials with each other to maintain their positional relationship, and the core plate whose main surface is the load applied from the shaft material. Support by the department.

According to the present invention, it is possible to easily improve the earthquake resistance of a wooden framed building by using a panel member with a shaft , which has never existed before, and it is possible to promote the use of a wooden framed building having many advantages in the future.

The perspective view which shows the beam part structure.

An embodiment for carrying out the present invention will be described below with reference to the drawings.

FIG. 1 shows a perspective view of the proof stress imparting panel member 11. The load-bearing panel member 11 is attached along with a shaft material of a wooden frame building, that is, a linear member that supports a load such as a pillar material, a beam material, a base, or a large pull, and is attached in a plane direction. By standing upright and fixing to the shaft material, the strength of the vertical structure is improved. Further, when the proof stress-imparting panel member 11 is laid horizontally in the surface direction and fixed to the shaft member, the proof stress of the horizontal structure surface is improved.

As described above, the proof stress-imparting panel member 11 is used together with the shaft material, and its area is naturally the area of a mass portion (referred to as "unit surface" for convenience in the present invention) such as a wall surface surrounded by the shaft material. Will be smaller than. The length of the proof stress-imparting panel member 11 may be the same as any side of the unit surface.

The proof stress-imparting panel member 11 is composed of a square core plate portion 12 and a edging portion 13 fixed to the edges of the four sides of the core plate portion 12 on both the front and back surfaces and sandwiching the core plate portion 12. It is united. The outer peripheral end surface 12a of the core plate portion 12 is flush with the outer peripheral surface 13a of the edging portion 13, and the four outer surface 11a of the proof stress-imparting panel member 11 are flat as a whole.

The core plate portion 12 is composed of a single plate material 21, and the shape of the core plate portion 12 in this example is a quadrangle in which all four corners are right angles, and the core plate portion 12 in this example is a rectangle. The size of the core plate portion 12 is formed according to the portion to be used on the unit surface, but the length in the longitudinal direction is set so as not to be too long in consideration of the bending moment and the like. When the length of the portion to be used becomes long in the longitudinal direction, a plurality of load-bearing panel members are arranged side by side.

The thickness of the core plate portion 12 is set in consideration of the required yield strength. As the plate material 21 used for the core plate portion 12, a plate material made of a load-bearing surface material such as a structural plywood can be preferably used.

The edging portions 13 on both the front and back sides are each composed of four square timbers 31, and are assembled in a square frame shape. As shown in FIG. 2A, which is a cross-sectional view taken along the line AA of FIG. 1, the square lumber 31 has a rectangular cross-sectional shape, and the lengths of the vertical a and the horizontal b are longer in the vertical a. It is formed. Note that FIG. 2B is a partial side view of the proof stress-imparting panel member 11.

Here, the vertical a is the direction corresponding to the thickness t of the load-bearing panel member 11 in the cross section of the square lumber 31, and the horizontal b is the direction corresponding to the width w of the edging portion 13.

The cross-sectional shapes of the square lumbers 31 used for the edging portions 13 on both the front and back sides are all the same size. That is, the thicknesses of the load-bearing panel members 11 in the edging portions 13 arranged on the front and back of the core plate portion 12 in the thickness t direction are the same as each other. Therefore, although the expressions "front" and "back" are used in this description, the proof stress-imparting panel member 11 can be used without distinction between the front and back.

Further, the total thickness of the core plate portion 12 and the edging portion 13, that is, the thickness t of the proof stress-imparting panel member 11, is the width wa of the side surface to be joined in the shaft material A to be attached, specifically, the shaft material A. It is the same. When the cross-sectional shape of the shaft member A to be joined is not a square but a rectangle, it may be the same as the widths wa and wb of either side surface. When the widths of the side surfaces of the plurality of shaft members A to be joined are different, the widths of the side surfaces of one of the shaft members may be the same.

The four square lumbers 31 may be joined to each other by cutting off the end faces at 45 degrees, but in the square lumber 31 of this example, the ends are cut off at a right angle to form the edge 31a (end face) of one square lumber 31. , The edge 31a of the other square lumber 31 is fixed in an exposed state by abutting against the side surface 31b of the other square lumber 31.

Such a core plate portion 12 and a edging portion 13 are fixed to each other by a fixing tool 14 such as a nail or a wood screw. That is, the edging portions 13 on both the front and back surfaces of the core plate portion 12 are connected to each other by the fixing tool 14 that penetrates one square lumber 31 and is inserted into the other square lumber 31. Specifically, as shown in FIG. 2, it may be fixed with, for example, wood screws 14a and 14b.

Two types of wood screws 14a and 14b, a long wood screw 14a and a shorter wood screw 14b, are used, and a plurality of wood screws 14a and 14b are struck at substantially equal intervals on the square lumber 31 constituting the edging portion 13, respectively.

As shown in FIG. 2B, the long wood screw 14a is longer than the sum of the length of the vertical a of the square timber 31 and the thickness of the core plate portion 12, and the thickness of the proof stress-imparting panel member 11 is longer. It is shorter than t. On the other hand, the short wood screw 14b is shorter than the sum of the length of the vertical a of the square member 31 and the thickness of the core plate portion 12, and is longer than the thickness of the core plate portion 12.

The shorter wood screw 14b is driven from the core plate portion 12 toward the square member 31 of the edging portion 13 on one of the front and back sides. The longer long lumber screw 14a is driven into the square lumber 31 of one edging portion 13 into which the shorter lumber screw 14b is shot, penetrates the core plate portion 12, and is inserted into the square lumber 31 of the other edging portion 13. .. As described above, the insertion directions of the long wood screw 14a and the short wood screw 14b are opposite directions.

In addition to these wood screws 14a and 14b, the wood screws 14a are struck from the side surface of one square member 31 having a right-angled portion to the edge 31a of the other square member 31. Further, a finishing nail (not shown) may be used to further join the joint portions of the square lumbers 31 to each other.

The proof stress-imparting panel member 11 including the core plate portion 12 and the edging portion 13 integrated with the wood screw 14a in this way has four outer surfaces 11a having a constant width forming a right angle to each other. Further, the proof stress-imparting panel member 11 has a rectangular recess 11b inside the edging portions 13 on both the front and back surfaces. The recess 11b exposes the inner peripheral surface 13b of the edging portion 13.

The core plate portion 12 cut into a rectangular shape is made of a plate material 21 that is easily distorted so as to be wavy because its four sides are sandwiched and solidified by the above-mentioned edging portion 13, that is, a lumbered square member 31 having a rectangular cross section. The four corners of the core plate 12 are regulated at an exact right angle. In addition to this, the end portion of the square lumber 31 constituting the edging portion 13 is cut at a right angle, and the edge (end face) 31a is applied to the side surface 31b of the other square lumber 31 to join the square lumbers 31 to each other. The correct right angle can be obtained at the corners of the edging portion 13.

Moreover, since the square lumber 31 constituting the edging portion 13 has a cross-sectional shape in which the vertical a is longer than the horizontal b, the core plate portion 12 can be more firmly solidified.

As a result, the outer surfaces 11a of the proof stress-imparting panel member 11 adjacent to each other become flat surfaces having a correct right angle without twisting.

The proof stress-imparting panel member 11 configured as described above is fixed to the shaft member A at the portion requiring strength in the wooden frame building. FIG. 3 shows an example thereof, and is an example of fixing between the upper portions of the pillar member 41 which is the shaft member A. A through member 42, which is a shaft member A, is passed between the column members 41, and the proof stress-imparting panel member 11 is fixed thereto, and the proof stress-imparting panel member 11 is also fixed to the column member 41. Further, the beam member 43, which is the shaft member A, is passed over the load bearing panel member 11 to fix the beam member 43 to the load bearing panel member 11, and the beam member 43 is also fixed to the column member 41. The cross-sectional shapes of the column member 41, the nuki member 42, and the beam member 43, which are the shaft members A in this example, are square, and their sizes are the same.

Fixing is performed using an appropriate joining metal fitting or fixative (not shown). When a fixing tool such as a nail or a wood screw is used to fix the load-bearing panel member 11 to the pillar material 41, the penetrating material 42, or the beam material 43, the fixing tool is the pillar material from the inner peripheral surface 13b of the edging portion 13. It is driven toward 41 mag. By fixing, the load-bearing panel member 11 is surrounded by the pillar member 41, the penetrating member 42, and the beam member 43 all around, and is integrated with these.

In the fixed state, the load-bearing panel member 11 regulates the left and right column members 41 in parallel, and at the same time, restrains the penetrating member 42 and the beam member 43 at right angles to the column member 41 to form a vertical structural surface.

At this time, the edging portion 13 of the proof stress-imparting panel member 11 maintains the fixed state with respect to the pillar material 41 or the like by mediating with the pillar material 41 or the like while solidifying the edge portion of the core plate portion 12. The core plate portion 12 supports the load on the surface while being assisted by the edging portion 13, and exhibits the proof stress while being dispersed throughout.

As described above, since the outer surfaces 11a of the load-bearing panel members 11 adjacent to each other can form a correct right angle, the load can be supported extremely well and the shaft members A to be fixed can be correctly restrained. ..

In particular, since the edging portions 13 on both the front and back surfaces of the core plate portion 12 are connected to each other by the fixing tool 14 that penetrates the one square lumber 31 and is inserted into the other square lumber 31, the integrity is high. Therefore, a high effect that the edging portion 13 solidifies the edge portion of the core plate portion 12 can be expected.

Further, since the recess 11b that exposes the inner peripheral surface 13b of the edging portion 13 is formed inside the edging portion 13, it is easy to fix the proof stress-imparting panel member 11 to the pillar material 41 or the like.

Moreover, since the combined thickness of the core plate portion 12 and the edging portion 13 is the same as the thickness of the shaft material A to be attached, the proof stress-imparting panel member 11 is simply applied to the required portion and the side surfaces are aligned flush with each other. Workability is good because an appropriate positional relationship can be obtained.

Next, the panel member 51 with a shaft using the above-mentioned proof stress-imparting panel member 11 will be described with reference to FIGS. 4 to 9.

The panel member 51 with a shaft is configured by joining the side surfaces of the shaft member S having a cross section corresponding to the cross section of the shaft member A to two parallel sides of the proof stress-imparting panel member 11.

Here, the "cross section corresponding to the cross section of the shaft member A" means that the shape and size of the cross section of the shaft member S are the same as those of the cross section of the shaft member A constituting the frame of the wooden frame building. It must be of the same size, of the same size, or of a larger size, and have the same value of either of the vertical cross-sectional lengths and can support the load in the same manner as the shaft member A. To say. The cross-sectional shape of the shaft member A in this example is a square. All or part of the shaft member A and the shaft member S may have other cross-sectional shapes.

As shown in FIG. 5, which is a cross-sectional view taken along the line BB of FIG. 4, the load-bearing panel member 11 and the shaft member S have a fixture 14 such as a wood screw 14a attached to the inner peripheral surface of the edging portion 13 of the load-bearing panel member 11. It is fixed by driving from 13b to the shaft member S.

In the panel member 51 with a shaft illustrated in FIG. 6, the load-bearing panel member 11 is juxtaposed between the shaft members S via a bundle member 52 having a cross section corresponding to the cross section of the shaft member A. be. The length and number of the proof stress-imparting panel members 11 to be provided are appropriately set according to the parts to be used. In the panel member 51 with a shaft of FIG. 6, two proof stress-imparting panel members 11 having the same size are arranged side by side.

The cross section of the bundle member 52 has the same shape and size as the cross section of the shaft member S, and the edge 52a is joined to an intermediate position in the longitudinal direction of the shaft member S. The length of the bundle member 52 is the same as the length of the short side of the load-bearing panel member 11, and the bundle member 52 is fixed between the two shaft members S together with the load-bearing panel member 11.

The fixing of the load-bearing panel member 11 to the bundle member 52 is performed by driving a fixing tool such as a wood screw from the inner peripheral surface 13b of the edging portion 13 of the load-bearing panel member 11 to the bundle member 52 in the same manner as described above.

The panel member 51 with a shaft configured as described above is fixed between the shaft members A, for example, a pillar material, a large pull, a beam material, etc., with the shaft member S lying sideways. The shaft member S is fixed to the shaft member A by using an appropriate joining metal fitting. The exposed surfaces of the load-bearing panel member 11 at both ends of the panel member 51 with a shaft in the longitudinal direction are in contact with the shaft member A and are pressed.

Since such a panel member 51 with a shaft includes a shaft member S, the number of member points can be reduced as compared with the case where the proof stress-imparting panel member 11 is used alone as shown in FIG. 3, and the construction is simplified. It can be transformed.

As shown in FIGS. 7 and 8, the shafted panel member 51 is preferably provided with a metal fitting 53 for joining to the shaft member A at at least a part of the end portion of the shaft member S. The position where the metal joint 53 is provided is at both ends of each of the two shaft members S of the two shaft members S, at both ends of any one of the shaft members S, or at both ends of the shaft member S. In some cases, it is only one end of S.

Appropriate metal fittings can be used for the metal joint 53, and the metal joint 53 in the illustrated example is an example, but the metal joint 53 is roughly divided into two. That is, there are a female joint metal fitting 53a having a nut portion into which a bolt is screwed, and a male type joint metal fitting 53b having a bolt portion screwed into the nut.

The panel member 51 with a shaft shown in FIG. 7A shows an example in which a female joint metal fitting 53a is provided at the ends of two upper and lower shaft members S. The female joint metal fitting 53a is made of metal, and as shown in FIG. 7B, the main body portion 54 having a nut portion and the main body portion 54 are integrally inserted into the shaft member S in the longitudinal direction thereof. It is composed of a plug piece 55.

The main body 54 has two parallel holding plates 54a and a nut member 54b held between the holding plates 54a and having a female screw in the center. The insertion piece 55 has a rectangular flat plate shape, and has a plurality of through holes 55a for inserting and fixing the drift pin 56.

In the panel member 51 with a shaft having such a configuration, the end surface in the longitudinal direction thereof is abutted against the side surface of the shaft member A, and the tip of the bolt 57 inserted from the opposite side of the shaft member A is screwed into the nut member 54b, for example. When tightened, it can be firmly fixed to the shaft member A.

The panel member 51 with a shaft shown in FIG. 8A shows an example in which a male joining metal fitting 53b is provided at the ends of two upper and lower shaft members S. The male joint metal fitting 53b is made of metal, and as shown in FIG. 8B, the main body portion 54 having a bolt portion and the main body portion 54 are integrally inserted into the shaft member S in the longitudinal direction thereof. It is composed of a plug piece 55.

The main body portion 54 is formed in a rectangular parallelepiped box shape having a size corresponding to the cross section of the shaft member S, and has openings 54c on two opposite side surfaces. A bolt 58 as a bolt portion penetrating in the same direction as the longitudinal direction of the insertion piece 55 is provided in the main body portion 54. That is, the tip of the bolt 58 protrudes from the tip surface of the main body 54, and the rear end exists in the notch 55b formed in the insertion piece 55. A rotation nut 58a is provided at a position corresponding to the inside of the main body portion 54 of the bolt 58 so that it cannot rotate relative to each other. Further, two nuts 58b and 58c are held so as to be relatively rotatable in a portion on the insertion piece 55 side of the rotating nut 58a. The bolt 58 is movable in its longitudinal direction.

The insertion piece 55 has a rectangular flat plate shape, and has a plurality of through holes 55a for inserting and fixing the drift pin 56.

The panel member 51 with a shaft having such a configuration is abutted against the side surface of the shaft material A, and the tip of the bolt 58 is screwed and tightened with respect to the female screw of, for example, the cylindrical core member 59 built in the shaft material A. .. Tightening is performed by rotating the rotating nut 58a from the opening 54c. After that, if the other two nuts 58b and 58c are moved in the direction of the insertion piece 55 and then operated like a so-called double nut, the nuts 58b and 58c can be firmly fixed to the shaft member A.

As described above, the shafted panel member 51 provided with the metal joint 53 is provided with the metal joint 53 at the end of the shaft member S to be joined to the shaft material A, so that the construction can be further simplified.

Moreover, since the metal joint 53 is fixed by bolts and nuts, even if it is once connected, it can be separated as needed. That is, even after the building is assembled, it is relatively easy to disassemble and reassemble it, reuse the members, replace some of the members, and relocate the building.

The panel member 51 with a shaft shown in FIG. 9 has a configuration in which a reinforcing face material 60 is provided on both sides. That is, a rectangular reinforcing face material 60 is attached to both sides of the shafted panel member 51 so as to conceal the recess 11b of the proof stress-imparting panel member 11. Since the thickness of the proof stress-imparting panel member 11 is the same as that of the shaft member S and the shaft material A to be attached, the reinforcing face material 60 can be satisfactorily fixed to the portion surrounding the proof stress-imparting panel member 11. In the fixed state, the reinforcing face material 60 is parallel to the core plate portion 12 of the load bearing panel member 11.

Fixtures such as wood screws are used for attaching the reinforcing face material 60. As the reinforcing face material 60, a load-bearing surface material such as a structural plywood can be preferably used.

Since the panel member 51 with a shaft provided with the reinforcing face material 60 as described above has a significantly improved bending strength, for example, when used for a beam, a wooden frame building having further improved seismic resistance can be easily obtained. ..

The reinforcing face material 60 may be provided in advance on the panel member 51 with a shaft, or may be attached to the proof stress-imparting panel member 11 and its peripheral portion after the proof stress-imparting panel member 11 is fixed to the shaft material A. ..

10 and 11 are front views showing an example of a wall panel 71 configured by incorporating the above-mentioned proof stress-imparting panel member 11 or the above-mentioned shafted panel member 51.

The wall panel 71 shown in FIG. 10 is an outer wall panel 71a that constitutes an outer wall of a wooden frame building, and is larger than a unit surface and has a size that can form a two-story building. 10 (a) is a front view of the outer wall panel 71a as viewed from the inside, and FIG. 10 (b) is a sectional view taken along the line CC of (a).

The outer wall panel 71a extends vertically and horizontally inside the frame portion 72 constituting the outer circumference, the load-bearing panel member 11 or the panel member 51 with a shaft laid horizontally at the beam portion forming position in the frame portion 72, and the frame portion 72. It is composed of a support material 73 and a face material 74 attached to the outer surface. The beam portion forming position is a position where the beam should exist, and in this example, it is an intermediate portion between the upper end portion and the vertical direction of the frame portion 72.

All four sides of the frame portion 72 are formed of the shaft member A, and the four corners are joined by a joining metal fitting 75 that connects the shaft members A at right angles. As the joining metal fitting 75, an appropriate one can be used.

A load-bearing panel member 11 is fixed under the shaft member A constituting the upper end of the frame portion 72, and a penetrating material having a cross section corresponding to the cross section of the shaft member A under the load-bearing panel member 11. 42 is laid down. Two load-bearing panel members 11 are arranged side by side via a bundle member 52 having a cross section corresponding to the cross section of the shaft member A on the left and right sides. In other words, if the shaft member A and the penetrating material 42 constituting the upper end of the frame portion 72 are considered to be the shaft member S of the shafted panel member 51, the upper end portion of the frame portion 72 may be configured by the shafted panel member 51. I can say.

A panel member 51 with a shaft is laid horizontally in the vertical intermediate portion of the frame portion 72.

A receiving portion 76 made of a square lumber for receiving a floor plate (not shown) is fixed to the inner side surface of the upper shaft member S in the shafted panel member 51 and the inner side surface of the shaft member A at the lower end of the frame portion 72. There is.

The support member 73 is made of a thin square lumber having the same length in the thickness direction of the outer wall panel 71a as that of the shaft member A and having a rectangular cross section. It is appropriately arranged so that the distance between the beam forming portion and the lower end shaft member A is maintained, desired rigidity can be obtained, and necessary windows and the like can be formed.

As shown in FIG. 10B, the face material 74 covers the entire outer surface including the beam portion forming portion, that is, the portion provided with the proof stress-imparting panel member 11, and is used for fixing nails, wood screws, or the like. It is fixed with a tool. As the face material 74, a load-bearing face material such as a structural plywood is preferably used.

The wall panel 71 shown in FIG. 11 is a partition panel 71b constituting a partition wall built inside a wooden frame building. The partition panel 71b has the same size as the unit surface, and unlike the outer wall panel 71a, its height corresponds to the height of the fixed floor.

The constituent members of the partition panel 71b are basically the same as those of the outer wall panel 71a, and the load bearing panel member 11 is laid horizontally on the frame portion 72 constituting the outer circumference and the upper end portion where the beam portion is formed in the frame portion 72. Alternatively, it is a panel member 51 with a shaft and a support member 73 extending vertically and horizontally inside the frame portion 72. The partition panel 71b may also be provided with a face material made of structural plywood or the like.

The frame portion 72 is made of a square lumber thinner than the shaft member A, that is, the same material as the support member 73 of the outer wall panel 71a described above. The four corners of the frame portion 72 are right angles, and are formed in an appropriate shape having a desired opening such as a door mounting portion together with the support member 73. The support material 73 is made of the same material as the support material 73 of the outer wall panel 71a described above, so that the distance between the beam forming portion at the upper end and the lower end can be maintained, the desired rigidity can be obtained, and the required opening can be formed. Arranged in.

The proof stress-imparting panel member 11 is fixed under the material constituting the upper end of the frame portion 72, and the piercing material 42 having a cross section corresponding to the cross section of the shaft member A is under the proof stress-imparting panel member 11. It is laid down. If the material constituting the upper end of the frame portion 72 is made of the shaft member S of the shafted panel member 51, the upper end portion of the frame portion 72 is made of the shafted panel member 51. Two load-bearing panel members 11 are arranged side by side via a bundle member 52 having a cross section corresponding to the cross section of the shaft member A on the left and right sides.

When such an outer wall panel 71a and a partition panel 71b are built to form a wall of a wooden frame building, a beam having a penetrating material 42 or a shaft member S, a proof stress imparting panel member 11, and a beam material 43 or a shaft member S is provided. A partial structure is obtained. As described above, the lumber 42 or the shaft member S is laid horizontally at the beam forming position between the pillars 41 as the shaft member A, and has a cross section corresponding to the cross section of the shaft member A. The proof stress-imparting panel member 11 is provided on the lumber 42. The beam member 43 or the shaft member S is provided on the load-bearing panel member 11 and is laid horizontally between the pillar members 41, and has a cross section corresponding to the cross section of the shaft member A.

FIG. 12 is a perspective view showing a beam portion of a wooden framed building having a beam portion structure composed of a plurality of outer wall panels 71a and a partition panel 71b in a manner of surrounding the beam portion structure like a frame. Is. For convenience, the face material 74 is omitted in FIG.

When the beam portion is configured in this way, the bending strength is improved by the strength-imparting panel member 11, so that the beam portion having a high yield strength can be configured without using a material having a high beam strength as in the conventional case. Moreover, since a material with a high beam length is not required, it is possible to reduce the types of materials required and improve the efficiency of construction.

As described above, if there is a proof stress-imparting panel member 11, it can be used independently, or one member can be configured as a panel member 51 with a shaft or a wall panel 71, and can be used in various ways depending on the situation. can.

Moreover, since the proof stress-imparting panel member 11 is smaller than the wall panel, it can be used not only for a newly built building but also for reinforcement or extension / renovation of an existing building, which is convenient.

By utilizing such a proof stress-imparting panel member 11, it is possible to promote the use of the wooden frame building even in a situation where the number of skilled workers is reduced, and it is possible to enjoy many merits unique to the wooden frame building.

The above configuration is one embodiment for carrying out the present invention, and the present invention is not limited to the above-mentioned configuration, and other configurations may be adopted.

For example, although the load-bearing panel member 11 is used in a horizontally long posture in the above-mentioned example, it may be used in a vertically long posture to form a sleeve wall or the like.

When the load-bearing panel members 11 are arranged side by side, the number of the load-bearing panel members 11 may be three.

The proof stress-imparting panel member 11 and the panel member 51 with a shaft may be formed in a size corresponding to a portion to be used or may be provided with a metal joint to form, for example, a “beam panel”.

When the proof stress-imparting panel member 11 is attached to a material corresponding to the shaft member A, the shaft member S, the above-mentioned penetrating material 42, etc., it is attached in direct contact with them, but indirectly. However, it does not matter.
