Description

The present invention relates to a load-bearing panel member suitable for construction, renovation, reinforcement, etc. of a wooden framework building.

Wooden frame buildings have a number of advantages, such as warmth and humidity control, excellent heat insulation, low environmental impact, people-friendliness, high degree of freedom in floor plans, and ease of extension and renovation. In order to obtain the earthquake resistance of such wooden framework buildings, load-bearing walls have conventionally been used. A load-bearing wall is constructed of braces and load-bearing panels whose usage and placement are calculated.

In order to improve workability, there has been proposed a load-bearing panel in which a load-bearing wall is made into panels, as disclosed in Patent Document 1 below. This load-bearing panel has a horizontal reinforcement part and a vertical reinforcement part inside the outer frame. It consists of horizontal or vertical shaft members and face members held between them and the outer frame.

A load-bearing panel with such a structure is very effective in that a load-bearing wall having a high load-bearing strength can be constructed simply by fitting it into a framework, and it is easy to construct 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 the wall and is large. In addition, as described above, the layout of load-bearing walls must be designed in advance.

Heretofore, no panel member has been available that can be used as a single member smaller than the wall to form a load-bearing wall.

This invention provides a load-bearing panel member that can be used for the construction of wooden frame buildings, extension and renovation, reinforcement of existing buildings, manufacturing of wall panels, etc. The main purpose is to promote the use of wooden frame buildings with the advantages of

Means for this purpose are panel members attached to the shaft members of the wooden frame building, and are fixed to the four side edges on both the front and back sides of the core plate portion made of a rectangular plate material and the core plate portion. It is a load-bearing panel member, which is composed of a rim portion made of rectangular timbers sandwiching the core plate portion, and the edge surface of the outer periphery of the core plate portion is flush with the outer peripheral surface of the rim portion.

In this configuration, the edging portion made of rectangular timber sandwiches and solidifies the four sides, which are the entire circumference of the core plate portion made of plate material, from both the front and back surfaces, thereby maintaining the entire core plate portion flat. The end surfaces of the four sides of the core plate and the outer peripheral surface of the edging portion flush with these are flat, thereby preventing the core plate portion and the edging portion from being displaced from each other. The load-bearing panel members are in contact with the side surfaces of the shaft members of a wooden frame building, and restrain the shaft members in contact with each other to maintain their positional relationship, and the load applied from the shaft members is mainly applied to the core plate, which is a surface. supported by the department.

According to this invention, it is possible to easily improve the earthquake resistance of a wooden frame building by means of an unprecedented load-bearing panel member, and to promote the future use of the wooden frame building, which has many advantages.

One mode for carrying out the present invention will be described below with reference to the drawings.

FIG. 1 shows a perspective view of the load-bearing panel member 11. As shown in FIG. The load-bearing panel member 11 is attached to a linear member that supports a load, such as a pillar member, a beam member, a foundation, and a large drawer, of a wooden framework building. By standing upright and fixing it to the shaft, the strength of the vertical structural surface is improved. Further, when the load-bearing panel member 11 is laid horizontally and fixed to the shaft member, the load-bearing strength of the horizontal structural surface is improved.

In this way, the load-bearing panel member 11 is used along with the shaft member, and the area of the panel member 11 is naturally the area of the wall surface surrounded by the shaft member. becomes smaller than The length of the load-bearing panel member 11 may be the same length as one of the sides of the unit surface.

The load-bearing panel member 11 is composed of a rectangular core plate portion 12 and edging portions 13 that are fixed to the edges of four sides on both front and back surfaces of the core plate portion 12 and sandwich the core plate portion 12 . bonded together. The end surface 12a of the outer periphery of the core plate portion 12 is flush with the outer peripheral surface 13a of the edging portion 13, and the four outer side surfaces 11a of the load-bearing panel member 11 are flat as a whole.

The core plate portion 12 is composed of one plate material 21, and the shape of the core plate portion 12 in this example is a quadrangle with all four corners being 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 longitudinal length of the part to be used is long, a plurality of load-bearing panel members are arranged.

The thickness of the core plate portion 12 is set in consideration of the necessary 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 structural plywood can be suitably used.

The edging portions 13 on both the front and back sides are each made up of four rectangular timbers 31, which are assembled in a square frame shape. As shown in FIG. 2(a), which is a cross-sectional view taken along line AA in FIG. 1, the square timber 31 has a rectangular cross-sectional shape, and the length a and the width b are longer in the length a. formed. 2B is a partial side view of the load-bearing panel member 11. FIG.

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

The cross-sectional shapes of the rectangular timbers 31 used for the edging portion 13 on both the front and back sides are all the same size. That is, the thickness in the thickness t direction of the strength imparting panel member 11 at the edging portions 13 disposed on the front and back of the core plate portion 12 is the same. Therefore, although "front" and "back" are expressed in this description, the load-bearing panel member 11 can be used without distinguishing between the front and back.

In addition, the total thickness of the core plate portion 12 and the edging portion 13, that is, the thickness t of the load-bearing panel member 11 is the shaft material A to be attached, specifically the width wa of the side surface of the shaft material A to be joined. are the same. If the cross-sectional shape of the shaft member A to be joined is not square but rectangular, it is sufficient that the widths wa and wb of one of the side surfaces are the same. Further, when the widths of the side surfaces of the plurality of shaft members A to be joined are different, the width of the side surface of any one of the shaft members is preferably the same.

The four square timbers 31 may be cut off at an angle of 45 degrees and the end faces thereof may be joined together. , and the side surface 31b of the other square timber 31, and fix the other square timber 31 in a state in which the edge 31a thereof is exposed.

The core plate portion 12 and the edging portion 13 are fixed to each other with fasteners 14 such as nails or wood screws. That is, the edging portions 13 on both the front and back sides of the core plate portion 12 are connected to each other by the fixtures 14 that pass through one square piece 31 and are inserted into the other square piece 31 . Specifically, as shown in FIG. 2, they may be fixed by wood screws 14a and 14b, for example.

The wood screws 14a and 14b are of two types, a long wood screw 14a and a shorter wood screw 14b.

As shown in FIG. 2B, the long wood screw 14a is longer than the sum of the vertical length a of the square timber 31 and the thickness of the core plate portion 12, and is equal to the thickness of the load-bearing panel member 11. It has a length shorter than t. On the other hand, the short wood screw 14b has a length shorter than the sum of the vertical length a of the square timber 31 and the thickness of the core plate portion 12 and 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 rectangular timber 31 of the edging portion 13 on one of the front and back sides. The longer wood screw 14a is driven into the square timber 31 of one edging portion 13 into which the shorter wood screw 14b is driven, penetrates the core plate portion 12, and is inserted into the timber 31 of the other edging portion 13. . Thus, the insertion directions of the long wood screw 14a and the short wood screw 14b are opposite to each other.

In addition to these wood screws 14a and 14b, the wood screw 14a is driven from the side surface of one square timber 31 forming a right angle to the edge 31a of the other square timber 31. As shown in FIG. Also, finishing nails (not shown) may be used to further join the joints between the square members 31 .

The load-bearing panel member 11 composed of the core plate portion 12 and the edging portion 13 integrated by the wood screws 14a in this manner has four outer side surfaces 11a of a constant width which are perpendicular to each other. Further, the load-bearing panel member 11 has a rectangular recess 11b inside the edging portion 13 on both the front and back surfaces. The recess 11b exposes the inner peripheral surface 13b of the edging portion 13. As shown in FIG.

The core plate portion 12 cut into a rectangular shape is formed of a plate material 21 that is easily distorted in a wavy manner because its four sides are sandwiched and hardened by the above-described edging portions 13, that is, the lumbered rectangular timbers 31 having a rectangular cross section. The four corners of the core plate portion 12 are regulated at right angles. In addition to this, the ends of the square timbers 31 forming the edging portion 13 are cut at right angles, and the ends (end surfaces) 31a of the square timbers 31 are brought into contact with the side surfaces 31b of the other square timbers 31 so that the square timbers 31 are joined together. A correct right angle can be produced at the corner of the edging portion 13. - 特許庁

Moreover, since the rectangular timber 31 forming the edging portion 13 has a cross-sectional shape in which the length a is longer than the width b, the core plate portion 12 can be solidified more firmly.

As a result, the outer side surfaces 11a adjacent to each other in the load-bearing panel member 11 become flat surfaces forming right angles without twisting.

The load-bearing panel member 11 configured as described above is fixed to the shaft member A in the portion of the wooden frame building that requires strength. FIG. 3 shows an example of this, in which the shaft material A is fixed between the upper parts of the pillar material 41 . Between the pillars 41, a cross member 42, which is a shaft A, is laid, and the load-bearing panel member 11 is fixed thereon, and the load-bearing panel member 11 is also fixed to the pillar 41. - 特許庁Further, the beam member 43 which is the shaft member A is stretched 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 shape of the column member 41, the cross member 42, and the beam member 43, which are the shaft member A in this example, is square, and their sizes are the same.

Fixing is performed using appropriate joining metal fittings and fixtures (not shown). When fixing tools such as nails and wood screws are used to fix the load-bearing panel member 11 to the pillars 41, cross members 42, and beams 43, the fixing tools extend from the inner peripheral surface 13b of the edging portion 13 to the pillars. It is driven towards 41 and so on. By fixing, the load-bearing panel member 11 is surrounded by the column member 41, the through member 42, and the beam member 43, and is integrated with them.

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

At this time, the edging portion 13 of the load-bearing panel member 11 hardens the edge portion of the core plate portion 12 and mediates with the pillar material 41 and the like to maintain the fixed state with respect to the pillar material 41 and the like. The core plate portion 12 supports the load on its surface while being assisted by the edging portion 13, thereby distributing the load over the whole and exhibiting the proof strength.

As described above, the outer side surfaces 11a of the load-bearing panel members 11 adjacent to each other can form a correct right angle, so that 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 sides of the core plate portion 12 are connected to each other by the fixtures 14 that pass through one square piece 31 and are inserted into the other square piece 31, the integration is high. Therefore, a high effect of hardening the edge of the core plate portion 12 by the edging portion 13 can be expected.

In addition, since the recess 11b exposing the inner peripheral surface 13b of the edging portion 13 is formed inside the edging portion 13, the work of fixing the load-bearing panel member 11 to the pillar member 41 or the like can be easily performed.

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 load-bearing panel member 11 can be applied to the required location and the side surfaces can be flushed. Workability is good because an appropriate positional relationship can be obtained.

Next, referring to FIGS. 4 to 9, a panel member 51 with a shaft using the above-described load-bearing panel member 11 will be described.

The panel member 51 with a shaft is configured by joining side surfaces of a shaft member S having a cross section corresponding to the cross section of the shaft member A to two parallel sides of the load-bearing 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 that constitutes the framework of the wooden framework building. In addition to being of the same size, or larger, the cross section shall have the same value for either the vertical or horizontal cross section, and be able to support the load in the same way as Axle A. Say. The cross-sectional shape of the shaft member A in this example is 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. The shaft member S is driven from 13b and fixed.

In the panel member 51 with a shaft shown in FIG. 6, the load-bearing panel members 11 are arranged side by side between the shaft members S with a bundle member 52 having a cross section corresponding to the cross section of the shaft member A interposed therebetween. be. The length and number of the side-by-side load-bearing panel members 11 are appropriately set according to the site to be used. A panel member 51 with a shaft in FIG. 6 has two load-bearing panel members 11 of the same size arranged side by side.

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

The load-bearing panel member 11 is fixed to the bundle material 52 by driving a fixture 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 material 52 in the same manner as described above.

The panel member 51 with a shaft configured as described above is fixed between shaft members A, such as pillars, girders, and beams, with the shaft member S lying on its side. The shaft member S is fixed to the shaft member A using an appropriate joint metal. The exposed surfaces of the load-bearing panel member 11 at both ends in the longitudinal direction of the panel member 51 with the shaft come into contact with the shaft member A and are pressed.

Since such a panel member 51 with a shaft is provided with the shaft member S, the number of members can be reduced compared to the case where the load-bearing panel member 11 is used alone as shown in FIG. 3, and construction is simple. be transformed.

As shown in FIGS. 7 and 8, the shaft-equipped panel member 51 preferably has a joint metal fitting 53 for joining the shaft member A to at least a part of the end portion of the shaft member S. The positions at which the metal joints 53 are provided are both ends of two of the two shaft members S, or both ends of one of the shaft members S. In some cases, it is only one end of S.

Appropriate metal fittings can be used for the joint metal fittings 53, and the joint metal fittings 53 shown in the figure are one example. That is, there are a female joining metal fitting 53a having a nut portion to which a bolt is screwed, and a male joining metal fitting 53b having a bolt portion to be screwed to the nut.

A panel member 51 with a shaft in FIG. 7(a) shows an example in which female joint metal fittings 53a are provided at the ends of two upper and lower shaft members S. As shown in FIG. The female joint metal fitting 53a is made of metal, and as shown in FIG. It is composed of an insertion piece 55 .

The body portion 54 has two parallel holding plates 54a and a nut member 54b held between the holding plates 54a and having a female thread at 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 .

The panel member 51 with a shaft having such a structure has its longitudinal end face abutted against the side surface of the shaft A, and for example, the tip of the bolt 57 inserted from the opposite side of the shaft A is screwed into the nut member 54b. When tightened, it can be firmly fixed to the shaft material A.

A panel member 51 with a shaft in FIG. 8(a) shows an example in which male joint metal fittings 53b are provided at the ends of two upper and lower shaft members S. As shown in FIG. The male joint metal fitting 53b is made of metal, and as shown in FIG. It is composed of an insertion piece 55 .

The body portion 54 is formed in the shape of a rectangular parallelepiped box having a size corresponding to the cross section of the shaft member S, and has openings 54c on two opposing side surfaces. A bolt 58 is provided in the main body portion 54 as a bolt portion penetrating in the same direction as the longitudinal direction of the insertion piece 55 . That is, the tip of the bolt 58 protrudes from the tip surface of the main body portion 54, and the rear end exists in the notch 55b formed in the insertion piece 55. As shown in FIG. A rotation nut 58 a is provided at a position corresponding to the inside of the main body portion 54 of the bolt 58 so as not to rotate relative to the bolt 58 . Two nuts 58b and 58c are held relatively rotatably 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 shaft-equipped panel member 51 having such a structure is abutted against the side surface of the shaft A, and the tip of the bolt 58 is screwed into the internal thread of, for example, a cylindrical core member 59 built into the shaft A and tightened. . Tightening is performed by rotating the rotation nut 58a through the opening 54c. After that, 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.

Since the panel member 51 with the shaft provided with the joining hardware 53 has the joining hardware 53 at the end of the shaft member S to be joined to the shaft member A, further simplification of construction can be achieved.

Moreover, since the joint hardware 53 is fixed by bolts and nuts, it can be separated if necessary even if it is once joined. In other words, it is relatively easy to disassemble and reassemble a building after assembling it, reuse members, replace some members, and relocate.

A panel member 51 with a shaft shown in FIG. 9 has a configuration in which reinforcing face members 60 are provided on both sides. That is, rectangular reinforcing face members 60 are attached to both surfaces of the shaft-equipped panel member 51 so as to hide the recess 11b of the load-bearing panel member 11 . Since the thickness of the load-bearing panel member 11 is the same as that of the shaft member S and the shaft member A to which it is attached, the reinforcing face member 60 can be well fixed to the portion surrounding the load-bearing panel member 11 . In the fixed state, the reinforcing face member 60 is parallel to the core plate portion 12 of the load-bearing panel member 11 .

Fixing tools such as wood screws are used to attach the reinforcing face member 60 . For the reinforcing face member 60, a load-bearing face member such as structural plywood can be suitably used.

Since the panel member 51 with a shaft provided with the reinforcing face member 60 in this way has a significantly improved bending resistance, for example, when it is used for a beam, a wooden frame building having improved earthquake resistance can be easily obtained. .

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

10 and 11 are front views showing an example of a wall panel 71 configured by incorporating the load-bearing panel member 11 or the panel member 51 with shaft described above.

The wall panel 71 shown in FIG. 10 is an outer wall panel 71a that constitutes the outer wall of a wooden framework building, and is larger than a unit surface and large enough to constitute a two-story building. FIG. 10(a) is a front view of the outer wall panel 71a viewed from the inside, and FIG. 10(b) is a sectional view taken along line CC of (a).

The outer wall panel 71a includes a frame portion 72 forming an outer periphery, a panel member 11 or a panel member 51 with a shaft that is horizontally mounted at a beam forming position in the frame portion 72, and extends vertically and horizontally inside the frame portion 72. It is composed of a support material 73 and a face material 74 attached to the outer surface. The beam formation position is the position where the beam should exist, and in this example, it is the upper end portion and the vertical intermediate portion of the frame portion 72 .

The frame portion 72 has four sides formed of the shaft members A, and the four corners thereof are joined by joining metal fittings 75 that connect the shaft members A to each other at right angles. Appropriate materials can be used as the joint metal fittings 75 .

Under the shaft member A constituting the upper end of the frame part 72, the load-bearing panel member 11 is fixed. 42 are laid across. Two load-bearing panel members 11 are arranged side by side on the left and right with a bundle 52 having a cross section corresponding to that of the shaft member A interposed therebetween. In other words, if the shaft member A and the through member 42 forming the upper end of the frame portion 72 are considered to be the shaft member S of the panel member 51 with shafts, then the upper end portion of the frame portion 72 can be configured with the panel member 51 with shafts. I can say.

A panel member 51 with a shaft is horizontally mounted on the middle portion of the frame portion 72 in the vertical direction.

On the inner surface of the upper shaft member S of the panel member 51 with shaft and on the inner surface of the shaft member A at the lower end of the frame portion 72, a receiving portion 76 made of a square member for receiving a floor plate (not shown) is fixed. there is

The support member 73 is composed of a thin square member having a rectangular cross section and a length in the thickness direction of the outer wall panel 71a that is the same as that of the shaft member A. They are appropriately arranged so as to maintain the distance between the beam forming portion and the shaft member A at the lower end, to obtain the desired rigidity, and to form necessary windows and the like.

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

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

The constituent members of the partition panel 71b are basically the same as those of the outer wall panel 71a. Alternatively, the shaft-equipped panel member 51 and the support member 73 extending vertically and horizontally inside the frame portion 72 are provided. The partition panel 71b may also be provided with a face member made of structural plywood or the like.

The frame portion 72 is entirely made of a square member thinner than the shaft member A, ie, 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 together with the support member 73 are formed into an appropriate shape having a desired opening such as a door mounting portion. The support member 73 is made of the same material as the support member 73 of the outer wall panel 71a described above, and maintains the distance between the upper end beam forming portion and the lower end so as to obtain the desired rigidity and to form the necessary opening. is placed in

Under the material constituting the upper end of the frame portion 72, the load-bearing panel member 11 is fixed, and under the load-bearing panel member 11, the through member 42 having a cross section corresponding to the cross section of the shaft member A is provided. Traversed. If the material forming the upper end of the frame portion 72 is made of the shaft member S of the panel member 51 with shafts, the upper end portion of the frame portion 72 is made of the panel member 51 with shafts. Two load-bearing panel members 11 are arranged side by side via a bundle 52 having a cross section corresponding to the cross section of the shaft member A. As shown in FIG.

When constructing the wall of the wooden framework building by erecting such an outer wall panel 71a and partition panel 71b, a beam having the cross member 42 or shaft member S, the load-bearing panel member 11, and the beam member 43 or shaft member S A partial structure is obtained. As described above, the through member 42 or the shaft member S spans across the beam forming position between the pillar members 41 as the shaft member A, and has a cross section corresponding to the cross section of the shaft member A. The load-bearing panel member 11 is provided on the through member 42 . The beam member 43 or the shaft member S is provided on the load-bearing panel member 11 and horizontally spanned 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 beams of a wooden framework building, which is a beam structure configured using a plurality of outer wall panels 71a and partition panels 71b, and is provided in a manner surrounding the beam structure like a frame. is. For convenience, FIG. 12 omits the face member 74 .

When the beam is constructed in this manner, the bending strength is improved by the strength imparting panel member 11, so that the beam can be constructed with high strength without using a high beam material for the beam as in the conventional case. Moreover, since a material with a high beam height is not required, the types of materials required can be reduced, and construction efficiency can be improved.

As described above, if there is a load-bearing panel member 11, it can be used alone, or it can be configured as one member as a panel member 51 with a shaft or a wall panel 71, so that it can be used in various ways depending on the situation. can.

Moreover, since the load-bearing panel member 11 is smaller than the wall panel, it can be used not only for newly built buildings but also for reinforcement, extension and reconstruction of existing buildings, and is convenient.

By utilizing such a load-bearing panel member 11, it is possible to promote the use of wooden framework construction even in a situation where the number of skilled workers is decreasing, and enjoy many advantages unique to wooden framework construction.

The above configuration is one mode for carrying out the present invention, and the present invention is not limited to the configuration described above, and other configurations can be employed.

For example, in the above example, the load-bearing panel member 11 is used in a horizontally long posture, but 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 load-bearing panel member 11 and the panel member 51 with a shaft may be formed in a size corresponding to the site to be used or provided with joint metal fittings, for example, as a "beam panel".

When the load-bearing panel member 11 is attached to the corresponding material such as the shaft member A, the shaft member S, or the above-described through member 42, it may be attached in direct contact with or indirectly attached to them. Either can be done or not.
