Description

The present invention relates to a structure having earthquake resistance and fire resistance used for a wooden house.
Specifically, the present invention relates to a structure having improved earthquake resistance and fire resistance used for a wooden house.
More specifically, the present invention relates to a structure with improved earthquake resistance and fire resistance used for a wooden house constructed by a wooden frame wall construction method, a so-called two-by-four construction method.

Recently, with the increasing interest in earthquake resistance, fire resistance and energy saving, interest in housing by wooden frame wall construction method, so-called two-by-four (2 × 4) construction method is increasing, and further earthquake resistance after the Great East Japan Earthquake. And the improvement of fire resistance is strongly required.
As a first prior art for improving earthquake resistance, a vibration damping device provided with a quadrangular frame formed in a quadrangle in a front view by a member including four constituent members, and disposed inside the quadrangular frame, The vibration control device is connected to the square frame by four braces extending radially from the vibration damping device, and the vibration energy of deformation of the square frame is transmitted to the vibration energy via the brace. In a structure with a damping device that absorbs by plastic deformation to suppress vibration, a bridging member is bridged between two structural members disposed facing each other among the four structural members. And a part of the bridging member is an overlapping portion overlapping with the vibration damping device in the front view, and the overlapping portion is perpendicular in a direction perpendicular to the front view. Vibration damping device with structures wherein the interference between the serial damping device is configured as an interference avoiding portion that is avoided is known (e.g., see Patent Document 1).
As a second prior art, a substantially horizontally supported lower wooden horizontal support, first and second wooden pillars spaced apart on the lower horizontal support, and these One end is joined to the middle part between the upper end and the lower end of the first pillar via a jointing fitting, and the other end is the above-mentioned jointing fitting. And a first brace joined to the second pillar at a position higher than a joint position by the first joint, and one end is joined to the middle portion of the first pillar via the joint metal fitting, and the other end is jointed by the joint metal fitting And a second brace joined to the second pillar at a position lower than a joining position, the joining metal fitting comprising a continuous plate-like member, fixed in contact with the side surface of the pillar It is continuous with the column fixing portion and the column fixing portion, and is bent so as to be folded back by a bending line in the vertical direction. And a brace fixing portion which is continuous with the pillar fixing portion via the folding portion and is substantially perpendicular to the pillar fixing portion and fixed to the side surface of the brace. Allowing relative displacement of one end of the two struts and the first column to which the struts are joined due to deformation of the joint in the axial direction of the first column; A bearing wall is provided between a pillar and a second pillar, and the pillar and the brace are connected by a nail, and a bearing wall is known (see, for example, Patent Document 2).
As the third prior art, the inner space of a pillar-girder structure formed by the adjacent pillars and the upper and lower ends of the bridge and the lower cross-bridge is bisected in the thickness direction. An upper support plate provided with a brace structure for wall strength enhancement having a pair of diagonal members crossing in a shape, and upper and lower ends fixed to upper and lower cross members in the other space divided in the thickness direction An earthquake resistant wall structure is known that is provided with a vibration reduction mechanism consisting of a pair of lower support plates and a combination of damper devices that connect these and dampen the relative movement between them in the horizontal and vertical directions. (See, for example, Patent Document 3).

JP-A-2016-000893 (FIGS. 1 to 5, paragraphs 0005 to 0007) Patent No. 589 3863 (FIGS. 1 to 16, paragraphs 0008 to 0064) JP-A-2002-188314 (FIGS. 1-8, paragraphs 0004-0050)

The first prior art has the advantage of being able to absorb the vibrational energy that the square frame deforms in a front view by the deformation of the damper and has the advantage of improving earthquake resistance. On the other hand, the upper and lower between the left and right components Since the bridging member (middle column) linking the structural members is arranged in parallel in the thickness direction of the damping tool and the bearing wall, a recess serving as an interference avoidance portion is provided in the middle of the bridging member. It is not possible to lock the bridging member with a fixing member such as a nail for fixing the plate-like body at the interval between the two. That is, since there is no bridging member in the portion facing the recess for avoiding the damping tool, the plate member constituting the structure is fixed to the bridging member by the plate fixing means such as nails. There is a problem that the fire protection structure rank can not be raised above a predetermined rank. This problem will be described using the conventional example shown in FIGS. The left vertical frame 4 and the right vertical frame, which are cross-sectional horizontal rectangles formed based on the predetermined standard on the upper surface of the lower frame 2 of the cross-sectional horizontal rectangle formed based on the predetermined standard, are arranged at predetermined intervals The lower end face of 6 is fixed, the upper frame 8 of the section rectangle formed on the basis of a predetermined standard is fixed to the upper end of the left vertical frame 4 and the right vertical frame 6, and further, above the upper frame 8 A head connector 12 formed on the basis of a predetermined standard is fixed, and a square frame 14 having a longitudinally long rectangular shape in front view is formed. In this conventional example, the circular damper 16 is fixed to the first bracket 18LU fixed to the side surface of the upper end portion of the left vertical frame 4, the second bracket 18LL fixed to the side surface of the lower end portion, and the upper surface of the right vertical frame 6. To the first connecting rod 22LU, the second connecting rod 22LL, the third connecting rod 22RU, and the fourth connecting rod 22RL, one end of which is fixed to the fourth bracket 18RL which is fixed to the lower end. It is connected and disposed at the center of the square frame 14. A middle column 24 is disposed between the left vertical frame 4 and the right vertical frame 6, the upper end thereof is fixed to the upper frame 8, the lower end is fixed to the lower frame 2, and a recess 26 is formed in the middle. Accept the chore 16. Plates 28 for the outer wall are provided on the outside of the rectangular frame 14 and gypsum boards 32 as the plate for the inner wall are provided on the inside at a pitch (distance) defined by the plate fixing means 34 such as nails. It is fixed to the lower frame 2, the left vertical frame 4, the right vertical frame 6, the upper frame 8, the head joint 12, and the center post 24. This pitch is at most 200 mm. In this case, the size of the recess 26 exceeds 200 mm in order to receive the damping member 16, and the plate fixing means 34 is driven into the front and back surfaces of the center post 24 at a pitch defined in the standard. I can not As a result, there is a problem that there is a limit to the improvement of the fire protection standard level because the fire protection standard does not meet the predetermined standard. In other words, even if a brace is used to improve earthquake resistance, in order to improve the fire protection standard level, the middle of the plate-like members fixed on both sides of the bearing wall is fixed to a plate-like member such as nail. It has to be fixed at predetermined intervals by means 34. However, as shown in the first prior art, when the recess 24 for receiving the damping tool 16 is formed in the center post 24, the center post 24 for fixing the plate fixing means 34 is provided on the inside opposite to the recess 26. It does not exist and can not be fixed at a predetermined interval by the plate fixing means 34. As a result, as described above, there is a problem that there is a limit to the improvement of the fire protection standard level.
Also in the second prior art, although the stud is used and the intersection with the brace is fixed by the nail, there is no escape to avoid interference with the brace such as a notch, so the stud is only on one surface of the wall It can not but understand that it is adjacent. By this, the plate-like body can be fixed to the stud at a predetermined pitch on only one surface constituting the load bearing wall by means of plate-like body fixing means such as nails, and one plate-like body is fixed to the stud by plate-like body fixing means As it can not be fixed, there is a limit to the improvement of the fire protection standard level as in the first prior art.
In the third prior art, the wall structure is bisected in the thickness direction, an X-type brace structure is disposed on one side, and a vibration reduction mechanism in which a damper device is combined is disposed on the other side. One or two middle bars are installed, and a plate-like reinforcing plate installed on one side of the wall structure is fixed by nails. Therefore, although one reinforcing plate of the wall structure is fixed to the middle rail by the plate fixing means, the other reinforcing plate can not be fixed to the middle rail, so that the fire standard level can be improved as in the first prior art. There is also a problem with limitations.

Damping struts 114S having a damping function are arranged in the diagonal direction of the square frame 102. The material which can not be driven or screwed into the wooden structure fixing means 134 means metal, composite resin structure or the like. As the bracing body 114, in addition to the damping bracing body 114S of the first embodiment, it is also possible to use an antiseismic bracing body 114R (see FIGS. 9 and 10) for improving the seismic strength. In addition, in addition to the structure in which the structures are arranged in an X-shape in the diagonal direction of the rectangular frame 102, one oblique structure or a plurality of inclined structures is used as the lower structure 104, the upper structure 106, and the left. The concept also includes a truss structure configured by obliquely connecting to the structure 108 or the right structure 112. Therefore, the diagonal direction is oblique to the lower structure 104, the upper structure 106, the left structure 108, or the right structure 112, in addition to the case where the bracing body 114 is on the diagonal of the square frame 102. Include the case. The brace body 114 is juxtaposed to the intermediate structure 116 in the thickness direction of the structure 100 in order to improve a predetermined earthquake resistance standard and load resistance. In other words, the struts 114 are offset from the center inward or outward in the thickness direction of the structural portion 100.

Next, the damping brace body 114S of the first embodiment will be described.
The damping brace 114S is non-combustible or non-combustible, and has a function of improving the lateral strength of the square frame 102 and damping the lateral vibration. The vibrator 136 and the bracing rod 148 are attached to the left structure 108 or the right structure 112 via the mounting body 142.

First, the vibration damping body 136 will be described.
The vibration damping body 136 is noncombustible or flame retardant and has a function of suppressing vibration by absorbing vibrational energy by the energy absorbing mechanism 138, and the energy is deformed by deformation of an oil damper, a visco-elastic substance, or metal. A passive damping mechanism that absorbs is employed. Passive damping mechanisms are advantageous in cost and long term operation stability. In particular, in the present invention, the damping body 136 is made of a non-combustible or flame-retardant material in order to satisfy a predetermined fire resistance function, and in the first embodiment, the damping body 136 is a metal, in particular, It is constituted by a circular damping ring 144 made of a relatively soft metal material such as aluminum or a relatively thin iron-based metal, preferably steel. However, as the material of the damping ring 144, a glass fiber composite material, a carbon fiber composite material, or an aramid fiber composite material can be adopted, and the shape thereof is a polygon such as a square or a hexagon, an ellipse or the like Any material that can absorb energy by deformation may be used. In the first embodiment, a bracing rod body 148 is provided radially in all directions from the damping body 136, that is, the damping ring 144. As in the first embodiment, when the damping body 136, that is, the damping ring 144 is made of a nonflammable material such as metal or a flame retardant material, there is an advantage that the fire resistance performance can be improved. On the circumferential surface of the damping ring 144, a bracket 146 having a channel-like cross section for connecting the cross bar 148 is provided.

In the predetermined position, respective forces acting on the damping ring 144 from the first bracket 146A, the second bracket 146B, the third bracket 146C, and the fourth bracket 146D in relation to the mounting body 142 described later It does not act as a shear force, but roughly it is a positional relationship that acts as a tension or compression force. Moreover, there is an advantage that fire resistance can be improved by the fact that the bracket 146 is nonflammable or flame retardant. Since the first bracket 146A, the second bracket 146B, the third bracket 146C, and the fourth bracket 146D all have the same structure, the third bracket 146C will be representatively described with reference to FIG. 5 (B). The third bracket 146C has a side view channel type by the left side plate 146L, the right side plate 146R, and the bracket bottom plate 146S, and an end portion of a third cross bar 148C described later between the left side plate 146L and the right side plate 146R.

In the first embodiment, four first brace bars 148A, second brace bars 148B, and third brace bars 148C, which are made of metal, have the function of generating (resistance). A fourth cross bar 148D is provided. The cross bars 148 are fixed to the left structure 108 or the right structure 112 via the mounting body 142. The noncombustibility or incombustibility of the bracing rod 148 is advantageous in that the fire resistance performance can be improved. One end of the first cross bar 148A is the first bracket 146A, one end of the second cross bar 148B is the second bracket 146B, and the third cross bar 148C is the third bracket 146C and the fourth cross bar 148D. Is connected to the fourth bracket 146D by a connecting pin 146P.

Next, the mounting body 142 will be described mainly with reference to FIG.
The mounting body 142 has noncombustibility or flame retardancy defined by a predetermined standard, and attaches the brace bar 148 to the lower structure 104, the upper structure 106, the left structure 108, or the right structure 112. In the first embodiment, the planar view made of metal is a channel-like bracket and is fixed to the left structure 108 or the right structure 112 by a standardized nail or the like in the first embodiment. . Specifically, the mounting body 142 corresponds to the first bracing rod 148A, the second bracing rod 148B, the third bracing rod 148C, and the fourth bracing rod 148D, corresponding to the first mounting body 142A, the fourth bracing rod 148D. A second mounting body 142B, a third mounting body 142C, and a fourth mounting body 142D are provided. Since the first mounting body 142A, the second mounting body 142B, the third mounting body 142C, and the fourth mounting body 142D all have the same structure, FIGS. 2B and 2C are representative of the first mounting body 142A. Description will be made using. The first mounting body 142A is formed in a plan view channel type by the inner side plate 142i, the outer side plate 142o, and the mounting body bottom plate 142S, and is vertically oriented between the inner side plate 142i and the outer side plate 142o. Receiving groove 142G is formed. The other end of the first cross bar 148A is inserted into the receiving groove 142G, and is attached to the first mounting body 142A by the first pivot pin 1421 and the second pivot pin 1422. Since the mounting body 142 is nonflammable or flame retardant, there is an advantage that fire resistance performance can be improved. In the first embodiment, the first mounting body 142A is fixed to the inner surface of the upper end portion of the left structure 108 by means of mounting body fixing means (not shown) such as standardized nails, and the second mounting body 142B is the left structure. The third attachment body 142C is fixed to the inner surface of the upper end portion of the right structure 112 by the attachment body fixing means (not shown). 4 attachment body 142D is being fixed to the lower surface part inner surface of the right structure 112 by attachment body fixing means (not shown). As shown in FIG. 2A, the first mounting body 142A, the second mounting body 142B, the third mounting body 142C, and the fourth mounting body 142D have a thickness direction of the structure 100, that is, the square frame 102. In the case of FIG. 2A, it is offset (set) inward (to the left in FIG. 2A). Thus, for example, when a force acts on the upper structure 106 in the right direction in FIG. 1, the left structure 108 and the right structure 112 tend to tilt to the right. As a result, a tensile force acts on the second cross bar 148B and the third cross bar 148C, a compressive force acts on the first cross bar 148A and the fourth cross bar 148D, and the upper structure 106 When moving in the left direction, forces act in the opposite direction, which provide resistance to the deformation of the square frame 102 and significantly improve the yield strength as compared with the case without the brace body 114. Further, in the first embodiment, since the vibration damping body 136 is interposed, the vibration energy can be attenuated by the deformation of the vibration damping body 136, thereby further improving the earthquake resistance. it can.

Next, the intermediate structure 116 will be described.
The intermediate structure 116 improves the load resistance of the structure 100 and a predetermined distance defined by the plate fixing means 152 in the middle of the left structure 108 and the right structure 112, preferably in the middle. For example, a standard wooden product having a function to fix the outer side plate-like body 122 at a distance (pitch) of 200 mm or less, and in the first embodiment, the cross section in the thickness direction of the structure 100 is a vertically long rectangle. In particular, two first intermediate structures 116L and two second intermediate structures 116R, each having a predetermined length and a rectangular cross section with a thickness of 2 inches and a width of 4 inches, are 2 × 4 wooden materials. It is provided. The lower end of the intermediate structure 116 is fixed by means of wooden structure fixing means 134 consisting of a plurality of standardized nails driven upward from the lower structure 104 or obliquely from the side of the intermediate structure 116, Are fixed by means of wooden structure fixing means 134 such as nails driven downward from the upper structure 106. Therefore, the intermediate structure 116 is disposed so as to be biased outward so that the outer end surface 116 o is flush with the lower structure outer end surface 104 o and the upper structure outer end surface 106 o in the thickness direction of the structure 100. It is arranged in parallel with the biased arranged brace body 114. Therefore, the brace 114 needs to have its thickness within the range of 2 inches excluding 4 inches of the thickness of the intermediate structure 116.

Next, the wall fixing structure 118 will be described.
The wall fixing structure 118 has a function of fixing the inner plate 124 at a predetermined distance, for example 200 mm or less, defined by the plate fixing means 152 such as nails, according to the present embodiment. 1, the standard wooden item whose cross section in the thickness direction of the structure 100 is a vertically long rectangle, specifically, the left wall fixing structure 118L is disposed between the left structure 108 and the intermediate structure 116. The right wall fixing structure 118R is disposed between the right structure 112 and the intermediate structure 116. Since the left wall fixing structure 118L and the right wall fixing structure 118R have the same configuration and are configured symmetrically with respect to the intermediate structure 116, the left wall fixing structure 118L is representatively described. The description of the same portion of the right wall fixing structure 118R will be omitted by replacing L with R and attaching the same. The left wall fixing structure 118L has a predetermined length, a rectangular horizontal cross section, and two adjacent 2 × 4 wooden members having a thickness (in the width direction of the square frame 102) of 2 inches and a width of 4 inches. Provided. In other words, the left wall fixing structure 118L is constituted by the first wall fixing structure 156L and the second wall fixing structure 158L, and the lower end of the left wall fixing structure 118L is upward from the lower structure 104 or It is fixed by the wooden structure fixing means 134 which is a standardized nail which is driven into the lower structure 104 obliquely downward from the side of the first wall fixing structure 156L and the second wall fixing structure 158L. In the thickness direction of the structure 100, the first inner end face 156Li and the second inner end face 158Li are the lower structure inner end face 104i and the upper structure by the wooden structure fixing means 134 which is a nail driven downward from the structure 106. It is disposed so as to be biased inward so as to be flush with the in-body end surface 106i, and a part thereof is disposed in the same plane 158 as the brace body 114 which is biased and arranged inside. Therefore, in order to avoid interference with the brace body 114, the wall fixing structure 118 is formed with a recess 162. Further, when the structure 100 is viewed from the side (thickness direction), as shown in FIGS. 2 and 3, the wall fixing structure 118 and the intermediate structure 116 are at the center in the thickness direction of the structure 100. It is set in an overlapping relationship. In the first embodiment, the overlapping amount is 2 inches.

Next, the recess 162 will be described.
The recess 162 has a function to receive the braces 114 placed on the same plane 158 so as not to interfere with each other, and in the first embodiment, the first brace fixing rod is used for the first wall fixing structure 156L. A first recess 162AU corresponding to the body 148A and a second recess 162AL corresponding to the second cross bar 148B are formed, and a third wall corresponding to the first cross bar 148A is formed on the second wall fixing structure 158L. A recess 164AU and a fourth recess 164AL corresponding to the second cross bar 148B are formed. The first concave portion 162AU, the second concave portion 162AL, the third concave portion 164AU, and the fourth concave portion 164AL, as shown in FIG. However, the first concave portion 162AU is formed to be offset upward in the vertical direction with respect to the third concave portion 164AU, thereby jointly forming a first concave groove 166LU with a lower right shoulder. Therefore, the first cross bar 148A can be positioned in the first recessed groove 166LU. In addition, the second concave portion 162AL is formed to be shifted downward in the vertical direction with respect to the fourth concave portion 164AL, thereby jointly forming a second concave groove 166LL with a right upper shoulder. Therefore, the second cross bar 148B can be located in the second recessed groove 166LL. Similarly, the third bracing rod 148C constitutes a third concave groove 166RU with a right upper shoulder composed of a fifth concave portion 162BU and a seventh concave portion 164BU, and the third crutch rod 148C is a third concave groove 166RU. Located in Similarly, the fourth bracing rod 148D constitutes a fourth recessed groove 166RL of a lower right shoulder composed of a sixth recess 162BL and an eighth recess 164BL, and the fourth bar 148D is a fourth recessed groove 166RL. Located in In other words, the first strut bars 148A and the second strut bars 148B can co-exist with the left wall fixing structure 118L in the same plane 158. Furthermore, the third struts 148C and the fourth struts 148D can coexist with the right wall fixing structure 118R in the same plane 158. The first recess 162AU, the second recess 162AL, the third recess 164AU, the fourth recess 164AL, the fifth recess 162BU, the sixth recess 162BL, the seventh recess 164BU, and the eighth recess 164BL cross each other at the construction site. Although it is general to construct by the electric saw while confirming the positional relationship with the body 114, in the standardized wood material manufacturing plant, the concave portion 162 is formed, and it is added when there is a disadvantage at the construction site You can also work on it.

Next, the outer side plate-like body 122 will be described mainly with reference to FIG.
The outer plate-like body 122 is disposed on the outer surface side of the structure 100, and is a nail standardized to the lower structure 104, the upper structure 106, the left structure 108, the right structure 112, and the intermediate structure 116. By being fixed to these by means of the plate fixing means 152 of the present invention, it has a function of at least strengthening the load resistance of the structure 100, and in the first embodiment, structural plywood for a wall of 9 mm in thickness is used. ing. Lower structure outer end surface 104o of lower structure 104 on the outer plate-like body 122 side, upper structure outer end surface 106o of upper structure 106, left structure outer end surface 108o of left structure 108, right structure of right structure 112 Since the body outer end face 112o and the intermediate structure outer end face 116o of the intermediate structure 116 are in contact with the outer plate-like body 122 as a whole, they have a predetermined spacing defined in the standard, for example, a spacing of 200 mm or less The outer plate-like bodies 122 can be fixed to them by means of the plate-like body fixing means 152.

Next, the inner plate 124 will be described.

End face 108i, right structure inner end face 112i of right structure 112, and wall fixing structure 118 (first wall fixing structure 156L, second wall fixing structure 158L) wall fixing structure inner end face By being fixed to these by means of plate fixing means 152 such as nails standardized to 118i, it has at least a function of strengthening the load resistance of the structure 100, and in the first embodiment, the thickness 12. A 5 millimeter fireproof structural plywood, specifically gypsum board, is used. The inner plate-like body 124 is adjacent to the lower structure inner end face 104i, the upper structure inner end face 106i, the left structure inner end face 108i, and the right structure inner end face 112i without a break. However, the wall fixing structure 118 (the first wall fixing structure 156L, the second wall fixing structure 158L) is provided at the portion facing the first concave groove 166LU to the eighth concave groove 167LL. There is no in-body end surface 118i. And since the length of the up-and-down direction of each 1st crevice 162AU-4th crevice AL exceeds the predetermined distance (200 millimeters) defined in the standard, the plate-like object fixed means 152 at the interval set in the standard. Can not be fixed by However, by using the first wall fixing structure 156L and the second wall fixing structure 158L adjacent to each other, the plate fixing means 152 can fix at an interval defined by the standard as described later. it can.

Next, the operation of the present invention will be described with reference to FIG.
FIG. 6 is an enlarged view of the first recessed groove 166LU formed in the first wall fixing structure 156L, which is an example in which a standardized nail is used as the plate fixing means 152. A wood screw etc. can also be used instead. The plate-like body fixing means 152 for fixing the inner plate-like body 124 is the lower side of the lower structure 104 at an interval equal to or less than the standardized reference interval LS, which is 200 mm in the first embodiment. It is fixed to the structure 106, the left structure 108, the right structure 112, or the wall fixing structure 118. Specifically, the first plate fixing means 1521 penetrates the inner plate 124 at the middle in the vertical position of the upper structure 106 and is driven into the upper structure 106. The second plate fixing means 1522 is driven into the lower second wall fixing structure 158L separated by the reference distance LS. The third plate fixing means 1523 is driven into the first wall fixing structure 156L slightly above the upper end of the first recess 162AU at a first interval L1 shorter than the reference interval LS. The fourth plate fixing means 1524 is driven into the second wall fixing structure 158L slightly above the upper end of the third recess 164AU at an interval shorter than the reference interval LS, which is the first interval L1 in the first embodiment. . The third plate fixing means 1523 can also be driven into the second wall fixing structure 158L. Next, the fifth plate fixing means 1525 is driven into the first wall fixing structure 156L slightly below the lower end of the first recess 162AU at the reference interval LS. Next, the sixth plate fixing means 1526 is driven into the second wall fixing structure 158L slightly below the lower end of the third recess 164AU at the reference interval LS. The sixth plate fixing means 1526 may be driven into the first wall fixing structure 156L. Similarly, the distance between the plate fixing means 152 is set shorter than the reference interval LS or the reference interval LS around the other second recessed groove 166LL, the third recessed groove 166RU, and the fourth recessed groove 166RL. I can do it. In other words, even if the inclination angle of the brace body 114 is increased by driving into the adjacent first wall fixing structure 156L and the second wall fixing structure 158L, the first wall fixing is performed. For example, by using the second wall fixing structure 158L and the second wall fixing structure 158L, in other words, the fourth plate-like member which is slightly impacted above the upper edge of the recess 164AU in the second wall fixing structure 158L. The fixing means 1524 and the fifth plate-like fixing means 1525 which are driven slightly downward from the lower end of the first concave portion 162AU of the adjacent first wall fixing structure 156L are driven into separate adjacent members. Therefore, it is possible to drive at intervals equal to or less than the reference interval LS. Furthermore, in other words, the inner side plate-like body 124 is fixed by the plate-like body fixing means 152 to the left wall fixing structure 118L while using a wood material standardized at a predetermined defined distance or less. Can. However, in the conventional method based on the vertical length LG of the first concave portion 162AU or the third concave portion 164AU, the length LG substantially exceeds the reference interval LS, and the inner plate 124 is spaced by the reference interval LS or less. Can not be fixed. However, in the present invention, by juxtaposing two standardized wooden materials in an adjacent state, the adjacent first concave portion 162AU and the second concave portion 162AL are used as the first wall fixing structure 156L and the second wall. By shifting in the longitudinal direction of the fixing structure 158L, the length of the recess in which the first cross bar 148A is located can be substantially shortened, and the inner plate 124 is separated by a distance less than or equal to the reference distance LS. It can be fixed by means of body fixing means 152. Although three or more standardized wood materials can be juxtaposed, it is preferable to use two in order to increase the space in the lateral direction of the plate fixing means 152 as the cost increases. In the first embodiment, the bracing body 114 can be a simple bracing member not using the damping body 136 or an anti-vibration bracing body 114R (see FIG. 9 or FIG. 10) as a pulling member. In this case, although the earthquake resistance of the structure 100 is lower than that of the vibration damping brace 114S, the earthquake resistance can be improved at a lower cost than that of the vibration damping brace 114S.

If the definition permits, the brace body 114 and the wall fixing structure 118 may be disposed outside, and the intermediate structure 116 may be disposed inside.

A second embodiment will now be described with reference to FIGS. 7 and 8.
In the second embodiment, the muscle body 114 is an example, and the same parts as those in the first embodiment are denoted by the same reference numerals, and different structures will be described. The brace 114 of the second embodiment is a second vibration damping brace 114B, and a fifth brace bar whose lower end is pivotally attached to a fifth bracket 146E fixed to the side surface of the lower end of the left structure 108. A body 148E, a sixth cross bar 148F pivotally attached to a sixth bracket 146F fixed to the upper side surface of the right structure 112, and an energy absorbing mechanism 138 are provided. The energy absorbing mechanism 138 is a damping damper 168 in the second embodiment, and is disposed so as to be biased inwardly as in the first embodiment, and it is preferable to use a metal damper for improving the fire resistance. In the second embodiment, a recess 162 is formed in the intermediate structure 116. Therefore, in the second embodiment, two intermediate structural bodies 116 are arranged by two 2 × 6 standardized wooden materials in the center between the left structural body 108 and the right structural body 112, and each has a recess. 162 is formed. Specifically, in the first intermediate structure 116L, a ninth concave portion 164L is formed at the middle in the vertical direction, and a tenth concave portion 164R is formed at the middle in the vertical direction of the second intermediate structure 116R, as shown in FIG. The fifth concave groove 166B is formed to be raised rightward. The fifth cross bar 148E is disposed in the fifth recessed groove 166B. Therefore, in the second embodiment, the wall fixing structure 156 (the first wall fixing portion) is in the same plane as the ninth recess 164 L of the first intermediate structure 116 L and the tenth recess 164 R of the second intermediate structure 116 R. And the second wall fixing structure 158L). As a result, the brace 114 and the intermediate structure 116 are juxtaposed in the thickness direction of the structure 100, and the ninth concave portion 164L and the tenth concave portion 164R are vertically offset. The groove 166B is configured. Therefore, also in the second embodiment, as in the first embodiment, the lower edge of the ninth recess 164L in the first wall fixing structure 156L and the upper edge of the tenth recess 164R of the second wall fixing structure 158L and Is shorter than the reference interval LS, it can be fixed at an interval equal to or less than the reference interval LS. Thus, the fire resistance of the structure 100 can be improved. The lateral depths of the ninth concave portion 164L and the tenth concave portion 164R are at most 2 inches in order to maintain the strength, and the plate fixing means 152 is omitted except for the intermediate structural body 116. Further, in the second embodiment, the brace body 114 can be replaced with a seismic brace body 114R as in the first embodiment.

A third embodiment will now be described with reference to FIG.
The third embodiment has one brace body 114 as in the second embodiment, but as in the first embodiment, the left wall fixing structure 118L and the right wall fixing structure are provided on the left and right of the intermediate structure 116, respectively. It is an example provided with 118R. Specifically, the brace 114 in the third embodiment is a seismic brace 114R. The earthquake resistant bracing body 114R is a bracing body having no vibration damping function, and simply refers to one in which the bracing body 114 for improving the load resistance is disposed between the structures. The first wall fixing structure 156L constituting the left wall fixing structure 118L is provided with an eleventh recess 163L as a recess 162 and a twelfth recess 165L as a second wall fixing structure 158L. As a result, a ninth concave groove 167L rising in the right shoulder is configured. The operation and effect in this case are also the same as in the first embodiment. The third wall fixing structure 156R constituting the right wall fixing structure 118R is formed with a thirteenth recess 163R which is a recess 162 and a fourteenth recess 165R which is a recess 162 in a fourth wall fixing structure 158R. As a result, a tenth concave groove 167R rising to the right is constructed. The tenth recessed groove 167R is disposed on the extension line of the ninth shoulder groove 167L. As a result, the earthquake resistant bracing body 114R can be positioned in the ninth recessed groove 167L and the tenth recessed groove 167R, and can be juxtaposed with the intermediate structure 116 in the thickness direction of the structure 100. In this state, the inner plate 124 is fixed by the plate fixing means 152 to the left wall fixing structure 118L and the right wall fixing structure 118R by the plate fixing means 152 according to the standard. It can be fixed at fixed intervals.

A central upper surface of the body 104 and a tenth bracket 146J are fixed to the left side surface of the right structure 112. To the seventh bracket 146G and the eighth bracket 146H, the end of the seventh strut rod 148G whose upper side is inclined to the right is fixed, and to the eighth bracket 146H and the ninth bracket 146I, the upper side is inclined to the left side. The end of the rod 148H is fixed, and the end of the ninth cross bar 148I whose upper side is inclined to the right structure 112 is fixed to the ninth bracket 146I and the tenth bracket 146J. To the seventh bracket 146G, end portions of a tenth bracing rod 148J whose upper side is inclined toward the left structural body 108 are fixed. These brace bars 148 function as resistors against lateral deformation of the structure 100. In the thickness direction of the structure 100, the first inner end surface 156Li and the second inner end surface 158Li are biased inward so as to be flush with the lower structure inner end surface 104i and the upper structure inner end surface 106i. The parts are arranged in the same plane 158 as the braces 114 which are arranged biased inwards. Therefore, in order to avoid interference with the brace body 114, the wall fixing structure 118 is formed with a recess 162. Further, when the structure 100 is viewed in the X-X line cross section in FIG. 10, the wall fixing structure 118 and the intermediate structure 116 overlap at the center in the thickness direction of the structure 100 as shown in FIG. It is set to a relationship. Also in the fourth embodiment, the overlapping amount is 2 inches.

The fifteenth concave portion 163LU, the sixteenth concave portion 163LL, the seventeenth concave portion 165LU, and the eighteenth concave portion 165LL are laterally-oriented rectangular concave portions opening toward the inside, and are formed to have approximately the same dimensions. The 163LU is formed to be shifted downward in the vertical direction with respect to the seventeenth concave portion 165LU, thereby jointly forming a seventh concave groove 167LU with a right upper shoulder. Therefore, the seventh cross bar 148G can be located in the seventh recessed groove 167LU. Further, the sixteenth recess 163LL is formed to be shifted upward in the vertical direction with respect to the eighteenth recess 165LL, thereby jointly forming an eighth recess 167LL with a lower right shoulder. Therefore, the eighth cross bar 148H can be located in the eighth recessed groove 167LL. The ninth cross bar 148H and the tenth cross bar 148J can be similarly positioned in the ninth concave groove 167RU and the tenth concave groove 167R. By this, the brace body 114 and the wall fixing structure 118 can coexist in the same space. Further, since the first inner end surface 156Li and the second inner end surface 158Li that constitute the left wall fixing structure 118L are provided flush with the lower structure inner end surface 104i and the upper structure inner end surface 106i, the inner side is configured the inner side. The plate-like body 124 can be fixed by the plate-like body fixing means 152 at an interval equal to or less than a predetermined interval defined in the standard, as in the first embodiment.
