Description

  The present invention relates to a damping wall for a wooden building, a wooden building provided with the damping wall, and a wall plate used for the damping wall of the wooden building.

  In general, buildings such as houses include wooden buildings and steel structures. In wooden buildings, wood is used for the main frame, whereas in steel structures, steel is used for the main frame. A wooden building and a steel building have different strength characteristics because the materials of the frames are different.

  By the way, in the steel structure building, the following structure is conventionally known as a damping structure that absorbs and relaxes external forces such as seismic force.

  (1) The structure which comprises the member of the layer where the external force concentrates in a building from a plasticizing member, a 1st elastic member, and a predetermined | prescribed 2nd elastic member (for example, refer patent document 1).

  (2) A structure in which a part of a member constituting a layer in which external force concentrates in a building is constituted by a predetermined plasticizing member (see, for example, Patent Document 2).

  (3) A structure in which a member on a floor where external force concentrates in a building is composed of an elastic member and a plasticizing member, and at least one of the section modulus is set based on a predetermined distribution (for example, Patent Literature) 3).

  (4) A structure in which both ends of two beams are connected by a connecting plate, a notch is formed at the ends of both beams, and a constricted portion is formed at the center of the connecting plate (for example, Patent Documents) 4).

  (5) A structure in which a predetermined through hole and a predetermined shear yielding portion are provided on the web of the beam (see, for example, Patent Document 5).

Furthermore, as a literature which disclosed the damping structure of the steel frame building, Unexamined-Japanese-Patent No. 2002-295053, Unexamined-Japanese-Patent No. 2003-49558, Unexamined-Japanese-Patent No. 2001-355348 etc. are mentioned (refer patent document 6-8). ).
Japanese Patent No. 2593313 (Claim 1) Japanese Patent No. 2961220 (Claim 1) Japanese Patent No. 2666617 (Claim 1) Japanese Patent No. 2939915 (Claim 1) Japanese Patent No. 3170557 (Claim 1) JP 2002-295053 A (Claim 1) JP 2003-49558 A (Claim 1) JP 2001-355348 A (Claim 1)

  Thus, as described above, since the wooden building has strength characteristics different from those of the steel frame building, it is assumed that the above structures (1) to (5) are applied to the wooden building. However, it was unclear whether the damping performance could be improved.

  Moreover, the structures (1) to (5) have the following difficulties.

  That is, in the structures (1) to (3), steel braces (bars) are attached as members that absorb the energy of external force, but it is difficult to attach braces to existing wooden buildings. Cost.

  Further, in the structures (1) to (3) described above, the order of deformation due to external force is such that the brace is plastically deformed after deformation occurs in the structure composed of columns (vertical members) and beams (cross members). ing. At this time, if the brace has too high rigidity, the brace does not undergo plastic deformation, and as a result, it cannot absorb the energy of the external force. Therefore, in order to reliably absorb the energy of the external force, a method of reducing the thickness of the blaze and setting the brace rigidity low is conceivable. However, since the brace is made of steel as described above, the brace thickness must be set very thin in order to ensure that the steel brace can absorb the energy of external force. Such a brace having a very thin thickness is liable to cause a mounting error and has poor handling properties.

  In the structures (4) and (5), a notch or a through hole is provided in a part of the beam. Therefore, in an existing building, such a notch or the like is provided in a part of the beam. If provided, the rigidity of the beam is lowered, and it is difficult to ensure the rigidity of the beam that is originally required.

  The present invention has been made in view of the above-described technical background, and an object thereof is to provide a damping wall for a wooden building having excellent damping performance, a wooden building having the damping wall, and a damping for a wooden building. It is in providing the wall board used for a wall. Another object of the present invention is that not only the installation work can be easily performed at the time of new construction, but also the installation work to an existing wooden building can be easily performed, and it is difficult to cause an installation error and is good. An object of the present invention is to provide a damping wall for a wooden building, a wooden building having the same, and a wall plate used for a damping wall for a wooden building having excellent handling properties.

  [11] The wall plate for a damping wall of a wooden building according to 9 or 10 above, which is made of aluminum or an aluminum alloy material whose yield strength divided by tensile strength is 0.6 or less.

  Next, the invention of each of the above items will be described.

  In the invention of [1], as a result of intensive studies to achieve the above object, the present inventors have used aluminum or an aluminum alloy plate as the damping wall plate, and the wall plate is made of woody material at the periphery. It has been found that a vibration-damping wall of a wooden building having excellent vibration-damping characteristics can be obtained by being fixedly attached to a wall frame.

  Moreover, according to this damping wall, the rapid deformation of the wall frame can be effectively delayed.

  Furthermore, in the invention of [1], not the steel plate but the aluminum or aluminum alloy plate is used as the wall plate, so that the following effects are exhibited.

  That is, if a steel plate is used as the wall plate, the following problems occur. That is, when a steel wall plate is attached to a wooden wall frame, the wall plate may be more rigid than the wall frame, and as a result, it may not be possible to absorb the energy of external forces such as seismic force. is there. Therefore, in order to reliably absorb the energy of the external force, it is necessary to thin the wall plate and set the rigidity of the wall plate, particularly the buckling strength, to be low. However, in order to reliably absorb the energy of the external force with the steel wall plate, the thickness of the wall plate must be set to a very thin thickness, for example, less than 1 mm. Such an extremely thin wall plate is likely to cause a mounting error such as a wrinkle at the time of mounting, and the wall plate is bent at the time of carrying.

  On the other hand, in this invention, since the aluminum or aluminum alloy plate is used as a wall board, the thickness of this wall board can be set thicker than a steel wall board. As a result, an attachment error can be made difficult to occur when the wall plate is attached to the wall frame, and good handling properties can be obtained. And since aluminum or aluminum alloy material is a lighter material than steel materials, there exists an advantage that the weight increase accompanying the thickening of a wall board hardly arises.

  In the damping wall of the present invention, the wall plate can be attached to the wall frame by using, for example, a mechanical coupling means (nail, screw, bolt, etc.) or / and an adhesive. Therefore, it is possible to easily perform the work of attaching the wall board at the time of new construction, and furthermore, it is possible to easily perform the work of attaching the wall board even when the wall board is attached to an existing building.

  Furthermore, since an aluminum or aluminum alloy plate is used as the wall plate, this wall plate can be easily cut and bent, and has excellent on-site workability. Therefore, it is possible to perform cutting or the like in accordance with the shape and size of the wall frame at the site of attachment work. In addition, as a processing tool at that time, a large-scale tool is not required, and the processing can be performed using a small general-purpose tool such as a saw or a hammer. Moreover, the remaining waste at the time of the processing and the removed wallboard can be reused using the current recycling route, and therefore, an increase in building waste can be suppressed.

  In the present invention, the means for attaching the wall plate to the wall frame is not limited. For example, as described above, mechanical coupling means (nails, screws, bolts, etc.) and bonding means by adhesion are applied. . Furthermore, a mechanical coupling means and a bonding means by adhesion may be used in combination.

  In the present invention, the wall frame is usually formed by assembling a pair of left and right wooden vertical members facing each other and a pair of upper and lower wooden horizontal members facing each other in a predetermined shape. Moreover, the wall frame should just be a wooden thing, and is not limited to the kind. For example, the material of the wall frame includes cedar, timber, and pine.

  In the invention of [2], the damping performance of the damping wall is further improved by using an aluminum or aluminum alloy plate having an elongation of 15% or more as the wall plate.

  In the invention of [3], the damping performance of the damping wall is further improved by using an aluminum or aluminum alloy plate having a value obtained by dividing the proof stress by the tensile strength as 0.6 or less as the wall plate.

  In the invention of [4], since the peripheral portion of the wall plate is fixed to the wall frame by mechanical coupling means, the work of attaching the wall plate to the wall frame can be easily performed at the time of new construction. Even when the wall plate is attached to the wall frame in the existing building, the attaching operation can be easily performed. Further, the amount of energy absorbed by the external force can be reliably increased, and therefore, a damping wall that reliably exhibits excellent damping performance can be provided.

  In the invention of [5], since the mechanical coupling means is a nail, the work of attaching the wall plate to the wall frame can be performed more easily at the time of new construction, and furthermore, the wall plate can be attached to an existing building. Even when it is attached to the wall frame, the attaching operation can be performed more easily.

  In the invention of [6], since the peripheral portion of the wall plate is fixed to the wall frame with an adhesive, the work of attaching the wall plate to the wall frame can be easily performed at the time of new construction. Even if it is a case where a wall board is attached to a wall frame in this building, the attachment operation | work can be performed easily. Further, the amount of energy absorbed by the external force can be reliably increased, and therefore, a damping wall that reliably exhibits excellent damping performance can be provided.

  In the invention of [7], since the periphery of the wall plate is superimposed on the surface facing the inner side of the wall frame, the periphery is fixed to the wall frame. Can be easily performed, and furthermore, even in the case where the wall plate is attached to the wall frame in an existing building, the attachment operation can be easily performed. Further, the amount of energy absorbed by the external force can be reliably increased, and therefore, a damping wall that reliably exhibits excellent damping performance can be provided.

  In the invention of [8], a wooden building having excellent vibration damping performance can be provided.

  In the invention of [9], since the wall plate is made of aluminum or an aluminum alloy material, the same effect as that of the invention of [1] is achieved by attaching the wall plate to a wooden wall frame.

  In the invention of [10], since the wall plate is made of aluminum or aluminum alloy material having an elongation of 15% or more, the same effect as the invention of the above [2] can be obtained by attaching the wall plate to a wooden wall frame. .

  In the invention of [11], the wall plate is made of aluminum or an aluminum alloy material having a yield strength divided by a tensile strength of 0.6 or less. Therefore, by attaching the wall plate to a wooden wall frame, the above [ The same effect as the invention of [3].

It is possible to provide a damping wall for a wooden building having

  Furthermore, since the thickness of the wall plate can be set thick, it is possible to make it difficult to cause an attachment error when the wall plate is attached to the wall frame, and it is possible to obtain good handling properties. Moreover, there is an advantage that almost no increase in weight due to thickening of the wall plate occurs.

  Furthermore, since the wall plate can be attached to the wall frame by using, for example, mechanical coupling means such as nails, screws, bolts, and / or an adhesive, the wall plate is attached at the time of new construction. In addition to being able to easily perform the mounting, the mounting work can be easily performed even when the wall plate is mounted on the wall frame of the existing building structure.

  Next, a preferred embodiment of the present invention will be described below with reference to the drawings.

  In FIG. 1, (1) is a wooden building according to an embodiment of the present invention. This wooden building (1) is made of wood in the framework of pillars (4), beams (5), etc. More specifically, it is a detached house, for example, and is assembled by a wooden frame construction method. Is. In the figure, (10) is a brace made of wood timber.

  This wooden building (1) has a damping wall (2). As shown in FIG. 3, the damping wall (2) is substantially composed of a wall frame (3) and a damping wall plate (6).

  The wall frame (3) is made of wood. Specifically, the wall frame (3) includes a pair of left and right wooden columns (4) and (4) as opposed to each other, and a pair of upper and lower wooden columns disposed opposite to each other. Beams (5) and (5) (including girders) as materials are assembled and formed in a generally square shape when viewed from the front. The wall frame (3) is not provided with braces. Both the column (4) and the beam (5) are made of wooden square lumber.

  In this wall frame (3), the columns (4) and beams (5) adjacent to each other are assembled and connected via various joints (not shown) such as tenons. In the present invention, the pillar (4) and the beam (5) may be connected by a nail, a screw, a bolt, or the like.

  The damping wall plate (6) (hereinafter abbreviated as “wall plate”) is made of plate-like aluminum or aluminum alloy material. That is, an aluminum or aluminum alloy plate is used as the wall plate (6). The material of the wall plate (6) is appropriately selected from, for example, JIS 1000 series, 2000 series, 3000 series, 4000 series, 5000 series, 6000 series and 7000 series aluminum or aluminum alloys. The wall plate (6) is preferably made of a stretched material of aluminum or aluminum alloy (for example, a rolled material or an extruded material). However, in this invention, a wall board (6) is not limited to this.

  The shape of the wall plate (6) is formed in a substantially square shape when viewed from the front. However, in the present invention, the shape of the wall plate (6) is not limited to this. Moreover, it is desirable that the thickness of the wall plate (6) is set in a range of 0.5 to 6 mm (particularly preferably 1 to 3 mm). However, in the present invention, the thickness of the wall plate (6) is not limited to this range.

  The wall plate (6) closes the entire space surrounded by the wall frame (3), and the peripheral portion of the wall plate (6) (that is, the upper, lower, left and right side edges) is the wall frame (3). In this state, as shown in FIGS. 1 and 2, the peripheral portion of the wall plate (6) (that is, the four side edges on the top, bottom, left and right) is a wall. The wall plate (1) is attached to the wall frame (3) by being fixed to the front surface of the frame (3) with a nail (7) at a predetermined pitch. It is desirable that the pitch of the nails (7) is set in a range of 10 to 100 mm (particularly preferably 25 to 50 mm). However, in the present invention, the pitch of the nail (7) is not limited to this range. In the present invention, the peripheral edge of the wall plate (6) may be fixed to the wall frame (3) by, for example, an adhesive, and further, for example, a mechanical coupling means and a bonding by bonding such as a glue nail. You may use together with a means.

  Thus, in this wooden building (1), if an external force (earthquake force, etc.) is applied to the wooden building (1) due to an earthquake or the like, the damping wall (2), for example, It is deformed obliquely in a plane including the wall (2) (for example, see FIG. 5 described later). As the damping wall (2) is deformed in this way, the energy of the external force is absorbed, thereby exhibiting excellent damping performance such as preventing the wooden building (1) from collapsing. In the damping wall (2), for example, the wall plate (6) buckles or the wall plate (6) and the wall frame (3) are joined together with the deformation of the damping wall (2). The portion breaks, or the joint between the column (4) and the beam (5) in the wall frame (3) breaks.

  In addition, in this embodiment, although the wall board (6) is attached to one place of a wooden building (1), in this invention, the place which attaches a wall board (6) is not limited to one place. It may be attached to a plurality of places. That is, the wall plate (6) is attached to an arbitrary wall frame (3) that requires vibration damping in the wooden building (1).

  Furthermore, in this wooden building (1), the wall plate (6) of the damping wall (2) is made of aluminum or an aluminum alloy material having a lower rigidity than that of the steel material, so that the wall plate (6) Can be set thicker than the steel wallboard. Therefore, an attachment error can be made difficult to occur when the wall plate (6) is attached to the wall frame (3), and good handling properties can be obtained. Moreover, since the aluminum or aluminum alloy material is a lighter material than the steel material, there is almost no increase in weight due to the thickening of the wall plate (6).

  Further, the wall plate (6) can be attached to the wall frame (3) by, for example, mechanical coupling means such as nails, screws, bolts, and / or an adhesive. Therefore, the installation work of the wall plate (6) can be easily performed at the time of new construction, and furthermore, even when the wall plate (6) is attached to an existing building, the installation work can be easily performed. It can be carried out.

  Further, since the wall plate (6) is made of aluminum or an aluminum alloy material, when the wall plate (6) is attached to the wall frame (3) by, for example, a nail (7), the nail (7) can be easily attached to the wall. The plate (6) can be penetrated, and there is an advantage that the nail (7) can be easily struck.

  Furthermore, since the wall plate (6) is made of aluminum or an aluminum alloy material, cutting and bending can be easily performed, and the on-site workability is excellent. Therefore, it is possible to perform cutting or the like in accordance with the shape and size of the wall frame (3) at the site of attachment work. In addition, as a processing tool at that time, a large-scale tool is not required, and the processing can be performed using a small general-purpose tool such as a saw or a hammer. Moreover, the remaining waste at the time of the processing and the removed wallboard can be reused using the current recycling route, and therefore, an increase in building waste can be suppressed.

  Here, in the present invention, the wall plate (6) is preferably made of plate-like aluminum or aluminum alloy material having an elongation of 15% or more. By doing so, the damping performance of the damping wall (2) can be further improved. In particular, the elongation of aluminum or aluminum alloy material is preferably as large as possible. Specifically, it is preferably 20% or more, 25% or more, 30% or more, or 40% or more. On the other hand, the upper limit of elongation is not particularly limited, and is set to 60% (preferably 50%), for example.

  Moreover, it is desirable that the wall plate (6) is made of plate-like aluminum or aluminum alloy material having a value obtained by dividing the proof stress by the tensile strength of 0.6 or less. By doing so, the damping performance of the damping wall (2) can be further improved. In particular, this value is preferably as small as possible. Specifically, it is preferably 0.5 or less or 0.4 or less. On the other hand, the lower limit value of this value is not particularly limited, and is set to 0.3 (preferably 0.35), for example.

  In the present invention, the mechanical properties such as elongation, proof stress and tensile strength of the wall plate (6) are adjusted to the desired properties by tempering the aluminum or aluminum alloy material constituting the wall plate (6). It can be adjusted reliably. As the tempering processing, for example, F processing, O processing, H processing, W processing, and T processing specified in JIS H0001 are preferably used.

  The preferred embodiment of the present invention has been described above. However, the present invention is not limited to the embodiment described above, and various settings can be changed.

  For example, in the present invention, the surface of the wall plate (6) of the damping wall (2) may be decorated. In this case, by attaching the wall plate to the wall frame with the surface of the wall plate exposed, the wall plate can be used as an interior plate or an exterior plate. Furthermore, since this wall board consists of aluminum or an aluminum alloy material, a decoration process can be performed easily. Examples of the decoration treatment include anodization treatment such as alumite treatment and printing.

  In the present invention, condensation may be prevented by coating the surface (or the back surface) of the wall plate (6) with a heat insulating material.

  In the present invention, the wall plate (6) may be provided with a reinforcing rib (not shown). In this case, the damping performance of the damping wall (2) can be reliably set to a desired performance.

  In the present invention, the wall plate (6) may be a flat plate, a corrugated plate, or a groove plate. When the wall plate (6) is a groove plate, the grooves of the groove plate may, for example, extend horizontally, extend vertically, or extend diagonally. Further, the wall plate (6) may have a uniform wall thickness over the entire wall plate, or may have a non-uniform wall thickness, for example, a taper material. good. In the case where the wall plate (6) is made of a taper material, the wall plate (6) is exemplified such that the wall plate (6) is set so that the thickness becomes thinner toward the center of the wall plate. Moreover, the wall board (6) may have a hole.

  Moreover, in this invention, you may give directionality to the shape of a wall board (6). For example, by providing a groove or a taper on the wall plate (6), it becomes possible to improve the vibration damping performance or to give directionality to the vibration sensitivity.

  In the present invention, the damping wall (2) may be applied to the flooring. For example, you may attach a wall board (6) to the location of the fire strike provided in the corner of the frame (floor frame) of the floor. Even in this case, the effect of the present invention can be obtained.

  In order to evaluate the damping performance of the damping wall of the present invention, the following tests were performed.

<Examples 1-8>
The damping wall (2) shown in FIG. 4 was produced. The wall frame (3) of the damping wall (2) is formed by assembling two pillars (4), (4) and beams (5), (5) in a substantially square shape. The wall plate (6) is attached to the wall frame (3) by fixing the peripheral portion of the wall plate (6) to the wall frame (3).

  In the wall frame (3) of the damping wall (2), both the pillar (4) and the beam (5) are made of cedar having a square cross section of 100 × 100 mm. The length L of the wall frame (3) in the height direction is 2700 mm, and the width W of the wall frame (3) is 900 mm.

  Table 1 shows the material, thickness, elongation, and yield strength / tensile strength values (that is, the value obtained by dividing the yield strength by the tensile strength) of the wall plate (6). The wall plate (6) is made of a rolled material or extruded material of flat aluminum or aluminum alloy. In addition, the numbers of “material of wall plate” in the table are all aluminum alloy numbers defined by JIS.

  In this damping wall (2), the wall plate (6) is attached to the wall frame (3) by the method shown in FIGS. 6 (a), 7 (a) and 8 (a). Adopted.

  In FIG. 6A, the peripheral edge of the wall plate (6) is overlapped with the front surface of the wall frame (3), and the peripheral edge of the wall plate (6) is nailed by the nail (7). The wall plate (6) is attached to the wall frame (3) (see FIG. 6B). The pitch of the nails (7) is 50 mm.

  In FIG. 7A, the peripheral edge of the wall plate (6) is fixed to the wall frame (3) with an adhesive in a state where the peripheral edge of the wall plate (6) is superimposed on the front surface of the wall frame (3). By doing so, the wall board (6) is attached to the wall frame (3) (refer FIG.7 (b)). In the same figure, (8) is the adhesion part of the wall board (6) by an adhesive agent.

  In Fig.8 (a), the peripheral part of the wall board (6) is overlapped with the surface facing the inner side of the wall frame (3), and the peripheral part of the wall board (6) is attached to the wall frame ( By fixing to 3), the wall board (6) is attached to the wall frame (3) (refer FIG.8 (b)).

The wall plate (6) is attached to the wall frame (3) by fixing the bent portion to the wall frame (3) with an adhesive. In FIG.8 (c), (8) is the adhesion part of the wall board (6) by an adhesive agent.

<Comparative example>
The wall plate (6) of the damping wall (2) of the above embodiment shown in FIG. 4 was not attached to the wall frame (3), that is, only the wall frame (3) was produced.

  With respect to the damping wall of the above example and the damping wall of the comparative example, an in-plane shear test was performed as shown in FIG. 5 to evaluate the damping performance. In the figure, P is a load, d is a deformation amount, and γ is a deformation angle (= d / L). Note that L is the length of the wall frame (3) in the height direction as described above. The evaluation results are shown in Table 1. Moreover, an example of the load-deformation angle curve about the damping wall (2) of an Example is shown in FIG.
