Abstract

<P>PROBLEM TO BE SOLVED: To provide a device, by placing in an appropriate place of an inner side of a wall of a wooden building, so as to reduce shaking motion of a whole building and to prevent the building from collapsing. <P>SOLUTION: An earthquake-damping grid body 1 is made by forming wood materials in a lattice shape. A contact point of a vertical member 2 and a lateral member 3 is not directly contacted to each other while a viscoelastic material 6 is filled in the space in the grid at the contact point, so that the vertical and lateral members are bonded and joined. By means of the joint, if either or both of the vertical and the lateral members are moved by some kind of force, the force applies mutually through the part bonded by the viscoelastic material. The grid body is placed within right/left pillars and top/bottom beams composing the building or in a single structural compartment 4 surrounded by sills. When a force from outside is applied and the building is going to be deformed, the gird body 1 is also deformed, but the viscoelastic material 6 filled in the contact point of the lattice part 7 produces viscoelastic deformation, so as to efficiently absorb the energy entering from outside and to reduce the deformation energy toward the other part of the building. Thus, the building can be safely maintained. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention is a damping lattice body to be constructed inside a wall surface of a building, and has an effect of improving the damping performance of the building.

  As conventional techniques, there are three types of measures for realizing a building that can withstand earthquakes: earthquake resistance, vibration control, and isolation. Among them, the conventional technology will be explained with regard to earthquake resistance and vibration control.

For wooden buildings, the development of “bearing wall panels” such as various types of wooden panels is thriving, and many products are offered. Speaking of wooden panels, the development of load-bearing wall panels was all. Wooden buildings can be strengthened by installing panels. This is specified in the Building Standard Law, and a strength table for each product has been established.
Hereinafter, a specific example will be described.

  The precast earthquake-resistant wall of Patent Document 1 (Japanese Patent Laid-Open No. 10-25921) relates to a precast earthquake-resistant wall (hereinafter also referred to as a PC wall) composed of beams and columns used in a reinforced concrete (hereinafter also referred to as RC structure) building. It is.

  The device shown in the “seismic wall material” of Patent Document 2 (Japanese Patent No. 2898563) is a single face panel in which a viscoelastic body is inserted between the face materials.

  Patent Document 3 (Japanese Patent No. 3627184) “wooden earthquake resistant wall forming a deformation absorbing layer” is applied to a building in which columns and beams are steel structures or reinforced concrete structures.

  On the other hand, in recent years, the idea of attaching a vibration control device to a building has been actively adopted. Many of the vibration damping devices are known to be attached near the joint between the beam and the column.

  The installation range of the “damping damper device” disclosed in Patent Document 4 (Japanese Patent Application Laid-Open No. 2000-110400) is applicable to buildings having columns or beams of steel structure or reinforced concrete structure.

The installation range of the “vibration control device” in Patent Document 5 (Japanese Patent Application Laid-Open No. 2004-239003) is adapted to a building having a steel structure or a reinforced concrete structure with columns and beams. In the present invention, the vibration damping property is increased by packing a material having viscoelasticity between the blocks when the blocks are stacked.
Japanese Patent Laid-Open No. 10-25921 Japanese Patent No. 29998563 Japanese Patent No. 3627184 JP 2000-110400 A JP 2004-239003 A

  However, buildings with load-bearing wall panels are a different idea from the viewpoint of vibration control. Buildings are not as good as they get stronger. If you build a strong wall all over the building according to the recent trend of emphasizing strength, you may get the illusion that a strong house can be made, and it will make you believe that a weak building is safe on the contrary. Has also appeared. For example, in the case of a house built in a house such as an urban area where there are no windows on the left and right sides of the house, and there are large windows in the front and rear, if this construction is done, there will be a part with no window Then the strength is extremely different. If this happens, there is a risk that the building will be less secure. When a disturbance force is applied to such a building, the side without the window is stiff, so the entire wall will be united and work in the direction of the wall with the window, and the wall with the window will be weak, so twisting and bending Wake up. This is an example of building a weak building that looks strong. If the load-bearing wall panels are installed in many parts simply because of the ease of construction, there is a drawback that the balance may be lost and rigidity may be deviated.

  As in the invention of Patent Document 1 described above, there is a problem that the PC product cannot be installed in the structural compartment because of a balance between weight and strength.

  The above-described invention of Patent Document 2 is an apparatus for a steel structure or a reinforced concrete structure, and the range of structures that can be applied differs from that of a wooden building. When a mechanism like this device is applied to a building using a small wooden frame construction method, and a heavy “seismic wall” is installed in the space of the left and right columns and upper and lower beams (or foundations), the “bearing wall” "The weight of the frame itself takes away the stress of the frame itself, making it weak overall. Moreover, the panel used by an earthquake-resistant panel construction method, etc. may protrude from a frame division plane with a deformation | transformation of a frame, and a muscle difference may protrude from a frame division plane similarly (FIG. 1 and FIG. 2 of patent document 2). Such a state is a phenomenon that causes a wall to be destroyed by disturbance force in an actual building.

  The wood used in the above-mentioned Patent Document 3 is a “high-strength wood” such as a laminated adhesive wood board, and the deformation energy is obtained by the viscous material attached between the high-strength wood and the columns and beams. The deformation absorbing layer has the function of absorbing. It is difficult to adapt to a wooden house that does not depend on high-strength wood, for example, a wooden frame building.

  In addition, the conventional vibration damping device is in common with the vibration damping grid body of the present invention in terms of “vibration suppression”, but many small-sized objects are far from the design value because of the balance with the structural material of the wooden building. There was a current situation that only the performance was allowed to appear.

  That is, in the vibration damper attached near the joint between the beam and the column of the wooden building, it may be necessary to attach to all the joints surrounded by the structural compartments in order to obtain a desired performance. If two dampers are attached to the top of the structural compartment and the lower part is used as a passage or room, walls must be created. No matter how compact the damping damper is, if you have to make a wall, it doesn't make sense to be compact. Therefore, the provision of a realistic and inexpensive vibration damping device has never been provided.

  With such a vibration damper installed near the joint between a beam and a column in a wooden building, even if the damper capacity is increased, the performance will not improve linearly until reaching a certain point, and further performance improvement can be expected. Disappear. Because the damper is installed near the joint between the beam and the column, the performance of the column and the beam (or foundation) is smaller than the performance of the damper, and the force that the damper originally must receive This is because a phenomenon that causes deformation force to the beam occurs. Because of this phenomenon, it is necessary to distribute the force with a large number of damper installation locations. However, installing dampers on all joints is an advantage that should come from the compactness of the dampers (for example, dampers). It is not necessary to use a wall even if it is attached to the wall, so that it can be used as a space, etc.), and the necessity of a compact shape is eliminated.

  The above-mentioned “damping damper device” of Patent Document 4 attempts to obtain viscous resistance and reduce deformation energy by sandwiching a viscoelastic material between plates such as low yield steel, but the steel material is made of wood. Since it has a stress of 20 times and a steel member is used in a wooden structure, the balance of the stress is poor, and there is a high possibility of causing a local increase in load on wood, etc. Absent. The “damping damper device” of Patent Document 4 is not applied to a small wooden frame building.

  The above-mentioned “vibration control device” of Patent Document 5 cannot load heavy blocks or the like in the wall, and even if such a thing is possible, the balance with the strength of the casing is poor. Therefore, such a method cannot be employed in a wooden frame building.

  Therefore, the present invention provides a damping lattice body that can be manufactured at a low cost and reduces vibrations of the entire building and prevents the building from collapsing by being placed in an appropriate place inside the wall surface of the building, particularly a wooden building. provide.

  Conventionally, panels developed for wooden houses and the like have been developed to increase the seismic performance, whereas the damping lattice body of the present invention is completely out of concept with conventional seismic panels or vibration control devices. It is different.

  That is, the invention of claim 1 has been made in view of the above problems, and a plurality of vertically assembled members are provided on a unit partition body of a main structure composed of beams, columns, and foundations or beams of a wooden building. A plurality of horizontally assembled members are attached in a lattice pattern in the space of the unit partition body, and a gap is formed at an intersecting portion of the vertically assembled member and the horizontally assembled member, and viscoelasticity or By being filled with a filler having elasto-plastic characteristics, a bonding portion is formed to keep the vertical assembly member and the horizontal assembly member in a lattice shape by the adhesive force of the filler, and due to the deformation energy applied to the unit compartment The vibration control lattice body is characterized in that the vibration is controlled by the coupling portion being displaced in the principal surface direction.

  The coupling portion of the damping grid body according to claim 1 is configured such that if either the vertical assembly member or the horizontal assembly member constituting the lattice, or both of them move with some force, the mutual force is exerted through the bonding portion of the filler. work. When an external force is applied to the building and the building is about to deform, the damping lattice body also deforms. However, the viscoelastic filler filled in the joint of the lattice causes elastic deformation and / or plastic deformation. It effectively absorbs the energy that has entered the building from the outside, reduces the deformation energy to other parts of the building, and works to make the vibration-damping performance fully demonstrated, and keeps the building safe.

  In the first aspect of the present invention, the amount of energy absorbed (deformation stress) by the viscoelastic filler having vibration damping damping force for one coupling portion may be small. Since any joint is designed to absorb deformation energy, as the number of joints increases, there will be more places where deformation stress will appear, and a small amount of force at each joint will gather, resulting in real performance. It will have enough characteristics to demonstrate. That is, the present invention is not a mechanism for improving only the current building strength, but expresses a vibration damping effect due to viscoelasticity in the building, so that the performance of the building can be improved comprehensively.

  Examples of the unit partition body include a unit partition body composed of columns, beams, girders, or foundations. For example, a rectangular unit block composed of two pillars, one beam or girder, and one base, two pillars, one window base (an example of a base), and one base The rectangular unit partition body is mentioned. It is preferable to construct the damping lattice body in a single unit compartment from the beginning. It is preferable that it is closely attached to all the structural members of the unit compartment.

  Examples of the filler include a gel material, a high molecular weight polymer material, silicon sealant, silicon caulking, multiple bond type oil, rubber (vulcanized rubber, thermoplastic rubber) and the like.

  In the invention of claim 2, the horizontal assembly member and the vertical assembly member are made of wood, and the cross-sectional area and the length of the wooden member are set to be smaller than the cross-sectional area and the length of the structural material constituting the unit partition body. The damping lattice body according to claim 1.

  The operation of the invention of claim 2 is characterized in that a deformation force is generated at the lattice point by the interaction of the vertical and horizontal assembly members.

  The invention according to claim 3 is the vibration damping lattice body according to claim 1 or 2, wherein the vertically assembled member and the horizontally assembled member intersect, and a long side of the vertically assembled member is parallel to the principal surface direction. .

  According to a fourth aspect of the present invention, the vertical assembly member and the horizontal assembly member are made of wood, set to a shape and size suitable for a wooden shaft conventional construction method, and also serves as a foundation for an outer wall or an inner wall of a building. 4. The vibration damping lattice body according to claim 1, wherein a spacer member is provided in an intermediate portion between the pillar and the pillar constituting the partition, and the spacer member is attached to the vertically assembled member or the horizontally assembled member.

  Invention of Claim 5 is installed in the position equivalent to the foundation | substrate of the outer wall panel of a building by selecting the edge part processing method of the said vertical assembly member or a horizontal assembly member, and constructs in the same surface as a column surface. Any one of 1 to 4 damping lattice bodies.

  A sixth aspect of the present invention is the damping lattice body according to the first or third aspect, wherein when the vertically assembled member and the horizontally assembled member are attached to the unit partition body, an end portion of the member is formed by a frame. Here, the “frame” means a single unit partition body according to claim 1 and is attached to the damping lattice body.

  In the invention of claim 7, a plurality of vertically assembled members and a plurality of horizontally assembled members are provided in the unit partition body of the main structure composed of beams, columns, and foundations or beams of a wooden building. And a gap is formed at an intersecting portion of the vertical assembly member and the horizontal assembly member, and a viscoelastic body or an elastic-plastic body is formed in the gap between the vertical assembly member and the horizontal assembly. By being arranged in a state of being engaged with the member, a connecting portion is formed to keep the vertically assembled member and the horizontally assembled member in a lattice shape by the elastic force of the viscoelastic body or elastic-plastic body. The vibration control lattice body controls vibration caused by deformation energy generated by the displacement of the coupling portion in the main surface direction. The coupling part may be an integral part, or may be divided into a plurality of parts and fitted together. The viscoelastic body or elastic-plastic body is preferably a rubber (vulcanized rubber, thermoplastic rubber), but is not limited.

  According to the first aspect of the present invention, no matter how the unit partition body changes or deforms, the damping lattice body deforms in the main surface direction of the unit partition body, and a direction different from the main surface direction (orthogonal direction) ), The phenomenon of protruding does not occur, and it does not have the effect of causing secondary destruction by deformation of the building.

  The damping lattice body of claim 1 can be constructed inside the unit partition body regardless of the current size or shape of the unit partition body (for example, pillar), and has a bad influence on the building. It is not added. It can be installed without affecting other building components such as studs and streaks inside the part surrounded by the unit compartment of the building. Therefore, it can be set as the structure used as the assistance for attaching the building material which forms an outer wall or an inner wall. Moreover, it can also be made the shape which does not contact the hardware etc. (for example, hole down anchor hardware) attached in order to maintain the unit division body of a building. The impact on the other parts of the building only attaches the additional situation of structural stability and does not do anything bad for the building. In addition, it is possible to flexibly change the mounting method according to various methods. Although it may not be possible to construct the damping grid on the entire wall part surrounded by a single unit partition, the performance is satisfied in proportion to the area of the damping grid, so Damping performance can also be calculated based on the area.

  According to the first aspect of the present invention, when the building is deformed, the deformation of the damping lattice body starts at the same time as the unit partition body, and damages the pillars, beams and foundations due to the characteristics of the damping lattice body. It has the feature of not.

  Since the damping lattice body of claim 1 can freely set the number of the lattices, it has the feature that the performance of the damping lattice body can be freely selected, enables a flexible design, and has a configuration of a space more than before. The degree of freedom can be increased. For example, the performance or weight of the damping grid can be adjusted by increasing / decreasing the number of coupling portions configured. For example, it is possible to improve the workability by setting the weight within a range in which a worker on the site of a wooden house can efficiently perform the work alone. In addition, it is a rational damping grid that can determine the final shape in consideration of the balance with damping performance.

  Depending on the magnitude of the force input to the damping grid body of claim 1 and the characteristics of the building part to be adapted, etc. The number of parts, the type of filler, etc. can be changed. Depending on the physical characteristics of the filling member, the elasticity can be increased or the plasticity can be increased. Since each of the joints exhibits damping characteristics and can be applied to a wide range, the damping stress of the damping grid body can be calculated at the time of design, the number of joints according to the building requirements, It is possible to flexibly cope with differences in the thickness of the filler and the mounting method. As described above, the property of the damping grid can be freely changed according to the property of the building to which the damping grid is applied, which can contribute to the improvement of the performance of the building. Moreover, it can change freely with the cross-sectional area of a vertically assembled member or a horizontally assembled member, a shape, required cost, required stress, etc., and can each exhibit predetermined force.

  The damping lattice body according to claim 1 is not only a portion surrounded by main unit partitions such as beams and columns, but also secondary unit partitions such as a waist wall and a small wall according to the shape of the building. Because it can be attached to the building, the necessary viscoelasticity can be easily added to the building.

  The damping lattice body according to claim 1 can improve the rigidity balance of the building. For example, a load-bearing wall panel is provided in a building to which the wooden shaft method, 2 × 4 panel method, or their hybrid method is applied, and a vibration-damping lattice body with the finished thickness is arranged in a proper position. By constructing the areas where there is no window side where the deformation force of the peripheral part is concentrated, the installation area of the load-bearing wall panel is reduced, and the rigidity imbalance of the walls on both the window side and the window-less side is corrected, and it is applied to the building. By adding elasticity, the seismic performance of the building can be improved comprehensively. There is also a product with the finished thickness equivalent to the load-bearing wall panel as a type of production, and the damping lattice body can add viscoelasticity or elastoplasticity to the building without adding unnecessary rigidity to the building.

  The vibration damping lattice body of claim 1 is maintenance-free and can exhibit a vibration damping effect during the lifetime of the building.

  According to the second aspect of the present invention, the members constituting the damping lattice body are made of wood, and the size of the wooden members is sufficiently smaller than that of the structural material. The finish can be easily processed in the same way as the other building materials that make up the building, and it can be installed in general work without using special tools.

  By combining the members of the damping lattice body having a small cross-sectional area and creating a large number of element portions that exhibit functions, the smallness of the members can be compensated for and the performance can be improved.

  Since the structural member of the damping lattice body of the present invention is different in the cross-sectional area and size from the structural member of the unit partition body of the building, the joint portion is much smaller than this, in contrast to the deformation stress of the structural member. Has only deformation stress. For this reason, the damping lattice body cannot adversely affect the unit partition body. Moreover, it is possible not to process force only in a very narrow range in the vicinity of the coupling portion, but to process force in all portions where the damping grid body is in contact with the unit partition body. Therefore, even if the performance of the damping lattice body is improved, a force that deforms the structural housing is not generated. By simply comparing the sizes of the cross-sectional shapes of the constituent members, it can be determined which member has high rigidity.

  It can be attached to the wooden frame in various ways, and it can be restored to its original state as the building is restored without being destroyed even by interlayer displacement.

  Because it is a size that can produce enough from thin trees such as thinned wood, it can be applied to the efficient use of thinned wood, etc., which is currently a problem in Japan It is possible to respond to forest recharge policies that are becoming social problems. Because it is made of wood, it is environmentally friendly when removed.

  According to the third aspect of the present invention, the vertically assembled member and the horizontally assembled member are orthogonal to each other, and the long side of the vertically assembled member is parallel to the principal surface direction when deformed by an external force. This is because the generation direction of the secondary moment of the cross section is studied and combined so that the vertical lattice member and the horizontal lattice member are most unlikely to receive deformation force of the member itself such as bending, bending, and shearing.

According to the invention of claim 4, since it is applied to a small-scale building of a wooden frame construction method, the materials constituting the left and right columns and the upper and lower beams (or foundations) are all wood, and have a steel structure or a reinforced concrete structure. Is a material that differs greatly in terms of rigidity, and can be constructed with sufficient strength by fully grasping the characteristics of being a wooden structure. It can be set as the mechanism which has the intensity | strength lower than the structural material which comprises a unit division body, and deform | transforms easily rather than a deformation | transformation of a unit division body material.
The present invention takes into consideration the characteristics of the structure of the wooden frame, and the weight is within a range that can be handled sufficiently by one worker, so that no load is applied to the structural section even after installation. For this reason, the members constituting the structure are of the same wood quality as the structure, and can be reduced in weight by using a lattice shape rather than a full wall.
Since the building to which the present invention is applied has a wooden frame structure, if the damping lattice body itself has a high rigidity, the housing may be damaged, and the number and structure of the coupling portions are configured in accordance with the strength of the building. Since the rigidity of the material can be changed flexibly, it has a characteristic that it can be adjusted to perform the most effective action.

  Furthermore, the damping lattice body can also serve as a base for the outer wall and a base for the inner wall. In the wooden shaft conventional construction method, an intermediate column is provided in the middle part between the columns, but the role of the intermediate column can be attached to the damping grid body by attaching the stud member to the damping grid body. It is. In addition, instead of attaching a stud, a vertical member constituting a damping lattice can be used as an alternative to play the role of the stud. The member in that case is also standardized, and efficient construction is possible.

  According to invention of Claim 5, it can provide also to the wooden house of the construction method using a load-bearing wall panel, and fully fulfill | performs the function as a foundation | substrate. In this case, the panel is constructed with a few millimeters protruding from the column surface, but by installing the damping grid with the same construction finish, the height of the finished surface of the panel and damping grid will be the same, and the outer wall It will be possible to perform construction without special consideration when folding the inner wall.

  According to the invention of claim 6, it is not necessary to attach the vertically assembled member and the horizontally assembled member to the unit partition body, and the ease of attachment can be improved.

  According to the invention of claim 7, the same effect as that of claim 1 is produced.

  Preferred embodiments of the present invention will be described below with reference to the drawings. The embodiment of the present invention is not limited to the following embodiment, and it goes without saying that various forms can be adopted as long as it belongs to the technical scope of the present invention.

[Embodiment 1]
Embodiment 1 of a damping lattice body 1 of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 5, the damping lattice body 1 is formed by assembling the vertically assembled member 2 and the horizontally assembled member 3 in a lattice shape to provide a rectangular lattice space 1 a, and the damping lattice body 1 is a main building of a wooden building. It is attached to the unit partition body 4 so as to be arranged in an inner region of the unit partition body 4 of the main structure composed of pillars, beams, and bases or beams which are structural parts. A gap 5 is formed at the intersection of the vertically assembled member 2 and the horizontally assembled member 3, and the gap 5 is filled with a filler 6 having viscoelastic properties, and the vertically assembled member 2 and the horizontally assembled member are bonded by the adhesive force of the filler 6. A coupling portion 7 is formed to keep the member 3 in a lattice shape. The vibration due to the deformation energy applied to the unit partition body 4 is controlled by the displacement of the coupling portion 7 in the main surface direction. The coupling portion 7 refers to an intersecting portion (intersection) of the damping lattice body 1 and includes the vertically assembled member 2, the horizontally assembled member 3, and the filler 6 existing at the intersecting portion.

  As shown in FIG. 1, a damping lattice body 1 composed of a vertically assembled member 2 and a horizontally assembled member 3 is attached between left and right pillars 4a and 4b, a beam 4c, and a base 4d. As for the mounting method, the columns 4a, 4b and the horizontal assembly member 3 are fixed by various methods such as fixing with a viscoelastic material, fixing with a nail, or fixing with an adhesive. I can do it. The connection between the beam 4c and the base 4d and the vertically assembled member 2 is the same.

  The vertically assembled member 2 and the horizontally assembled member 3 are made of wood, and the cross-sectional areas and lengths of the wooden members 2 and 3 are set to be smaller than the cross-sectional areas and lengths of the structural members 4 a to 4 d constituting the unit partition body 4. ing. As shown in FIG. 3, the vertically assembled member 2 and the horizontally assembled member 3 are orthogonal to each other, and the vertically assembled member 2 has a shape that penetrates the vertical through hole 3 a of the horizontally assembled member 3. The long side of the vertically assembled member 2 is parallel to the main surface direction, and the short sides are orthogonal. The long side of the horizontal member 3 is parallel to the main surface direction, and the short sides are orthogonal. A plurality of vertical through holes 3a penetrate the horizontal assembly member 3 in the vertical direction, and a predetermined number is formed at a predetermined interval or an appropriate interval.

  As shown in FIGS. 4 and 5, a rectangular gap 5 having a bright cross section is formed between the vertically assembled member 2 and the horizontally assembled member 3 at the intersecting portion of the vertically assembled member 2 and the horizontally assembled member 3. Formed so that the vertically assembled member 2 and the horizontally assembled member 3 are not in direct contact with each other, and the thickness of the gap 5 in the axial direction of the horizontally assembled member 3 is set larger than the thickness in the direction orthogonal to the axial direction. Yes.

  The vertically assembled member 2 and the horizontally assembled member 3 are set in a shape and size suitable for a wooden shaft conventional construction method, and also serve as a foundation for the outer wall of the building or a foundation for the inner wall. An inter-column member 8 is provided at an intermediate portion between the column 4b constituting the unit partition body 4 and the adjacent column 4c. The spacer member 8 is connected to the beam 4c and the base 4d, and is attached to the spacer 4 adjacent to the pillar 4b connected to the horizontal member 3.

  The vertically assembled member 2 and the horizontally assembled member 3 constituting the coupling portion 7 are not tightly coupled, but are joined together with an appropriate space therebetween, and the viscoelastic filler 6 is inserted in a portion therebetween. It has become. The filler 6 shows resistance so that when the vertically assembled member 2 and the horizontally assembled member 3 constituting the lattice move according to the deformation of the building, they remain in their original shapes. At this time, the deformation energy is converted as the deformation energy of the viscoelastic material, and the input of energy to the entire building is relatively reduced. This indicates that the damping lattice body is effective.

  The vertically assembled member 2 of the lattice constituting member of the damping lattice body 1 has a mechanism for constituting a lattice through holes formed in the horizontally assembled member 3. The hole opened in the horizontal assembly member 3 is larger than the outer dimension of the vertical assembly member 2. The viscoelastic filler 6 is filled in the large gap 5 (space location), thereby adding a function of exhibiting viscous resistance to each coupling portion 7. The interval between the parts formed by the vertically assembled member 2 and the horizontally assembled member 3 of the coupling portion 7 has an important function for determining the amount of the viscoelastic filler 6. The viscous resistance force of the coupling portion 7 is determined by the size of the interval, and the magnitude of the viscous resistance force of the entire damping lattice body is determined.

  Examples of the filler 6 shown in FIGS. 4 and 5 include the following. Gel substance is a natural material, has many ecological substances, and is characterized by being environmentally friendly. However, it is water-based and has water retention and wetting problems. Many high molecular weight polymer systems have been developed, ranging from rubber properties to viscous properties. Silicone sealant is a so-called caulking agent. It has a certain degree of viscosity, but its basic property is curable. The effect is exhibited when the displacement is small. Multi-bonded oils, for example, oxygen-polymerized oils such as linseed oil, take a long time to dry, but can be used as energy absorbers for vibration control devices. By appropriately selecting from the above substances, a filler having appropriate performance can be found.

  The response at the time of the disturbance force input of the damping lattice body 1 according to the first embodiment will be described. At the time of earthquake or wind pressure influence, the damping lattice body 1 is deformed together with the unit partition body 4 in the main surface direction as shown in FIG. The deformation of the building moves the unit partition body 4 from a rectangular state to a parallelogram shape to the left and right. In this case, the vertical assembly member 2 and the horizontal assembly member 3 constituting the damping lattice body 1 are used. Similarly, since the shape changes from a rectangular shape to a parallelogram shape, the shape change of the unit partition 4 and the shape change of the damping lattice 1 are in a similar relationship. As for the vertically assembled member 2 connecting the beam 4c and the base 4d, a phenomenon occurs in which the upper part and the lower part are shifted to the left and right, and the horizontally assembled member 3 attached between the pillars 4a and 4b moves in parallel. . Looking at the movement of each member, the horizontally assembled member 3 of the damping lattice body 1 moves substantially in parallel, and the vertically assembled member 2 performs a circular motion around one end. The deformation angle between the vertically assembled member 2 and the horizontally assembled member 3 of each lattice is constant at any point, and the deformation energy is uniformly distributed. Because of this feature, a non-uniform distribution of stress does not occur in the constituent plane of the damping lattice body 1, and a very stable reaction is exhibited. Further, since the stress is uniformly distributed, no stress concentration occurs. Since the damping lattice body 1 is arranged in the structural axis of the unit partition body 4 and is sufficiently weaker than the strength of the members constituting the structural axis, Deformation easily occurs following the deformation of the structural axis.

  FIG. 7 shows the characteristics of the damping lattice body 1. The area surrounded by the line indicates the amount of absorbed energy with respect to the deformation energy due to the disturbance force. The energy absorption amount (deformation stress) by the viscoelastic filler having the damping damping force in one coupling portion 7 may be small, and any coupling portion 7 is adapted to absorb deformation energy. When the number of the coupling parts 7 increases, the number of places where deformation stress appears increases, and a small amount of force at each coupling part gathers, so that it has characteristics sufficient to actually exhibit damping performance.

  Several methods have been established for assembling the damping lattice body 1 into the building by assembling it with the building body. As a development system, a damping lattice body that has been pre-installed in a frame so that it can be put in the unit partition body 4 and a damping lattice assembly for a 2 × 4 construction method are also considered. It must be considered for the construction of hole-down hardware. As a general rule, the damping lattice body 1 is constructed in a place that is not basically a bearing wall. Specific examples of construction will be described later.

A caulking agent is used as a filler. The pitch of the damping lattice body 1 is 151 mm × 151 mm (the distance between the central axes of the vertically assembled member 2 and the horizontally assembled member 3), the lengths of the columns 4a and 4b are 2595 mm, and the axial direction of the vertically assembled member 2 is The gap is 1019 mm, the width (long side) is 60 mm, the depth (short side) is 30 mm, the overall length of the horizontal assembly 3 in the axial direction is 910 mm, the height (short side) is 30 mm, and the depth (long side) is 60 mm. To do. The vertical through hole has a depth of 32 mm, a horizontal width of 80 mm, and a height of 30 mm. In the cross section of the gap 5, the narrower width is 1 mm and the longer width is 10 mm. The volume of the gap 5 is (32 × 80 mm−30 × 60 mm) × 30 mm (height) = 22,800 mm ³ (22.8 cc). Since there are 85 intersections, when the gap is completely filled, the capacity is 22.8 × 85 = 1938 (cc). The reason why the vertically assembled member and the horizontally assembled member are 30 mm × 60 mm members is that they can be effectively used and produced efficiently. In addition to 151 × 151 mm, the pitch of the lattice includes 90 × 90 mm, 200 × 200 mm, 303 × 303 mm, 180 × 151 mm, 175 × 151 mm, and the like.

  The shape of the material of the vertically assembled member 2 is such that the length of the long side is twice that of the short side, so that the strength is 8 times different between the weak direction and the strong direction. The number of coupling portions 7 increases as the density increases. Basically, the deformation of the lattice portion 7 is the same regardless of the lattice point portion. With respect to the displacement of the horizontal member 3, deformation stress appears surely at each lattice point (intersection point) by relative movement with the displacement of the vertical member 2. Each intersection has the same function in calculation and shares the force. Therefore, the larger the number of lattices, the smaller the necessary strength of the material itself, but the more material is used and the weight increases. Considering workability at the actual site, it is desirable that it is about 20 kg even if it is heavy.

[Embodiment 2]
The damping grid body 11 of Embodiment 2 will be described with reference to FIGS. 8 and 9. In addition, about a common structure, parts numbers are set to the 10th level, and the difference and description are demonstrated using the illustration and description of Embodiment 1. FIG. The vibration control lattice 11 is different in the crossing mode of the vertically assembled member 2 and the horizontally assembled member 3. The vertically assembled member 12 and the horizontally assembled member 13 constituting the damping lattice body 11 have a structure in which one is not penetrating through the other hole but intersects while adjoining. In this structure, the adjacent gap 15 is filled with a viscoelastic filler 16, and the filler 16 gives a viscous resistance to the entire damping lattice body 1.

The same applies to the left column (not shown). A vertical through-hole 14g is formed in the base 14d, and the lower end of the vertical assembly member 12 is fitted and fixed. The same applies to beams (not shown).

  The advantage of the assembly method of the second embodiment is that it is not necessary to perform additional processing for constructing the damping lattice body 1 such as drilling. Further, since the magnitude of the viscous resistance is determined by the area of the filler, a relatively large area can be secured and a large viscous resistance force can be exhibited.

Usually, the damping lattice bodies 1 to 101 are attached to the space surrounded by the left and right columns and the upper and lower beams or girders or foundations. For this reason, the mounting structure is such that the damping grating body 1 can also be used as a base for this purpose. That is, in a building where an earthquake-resistant panel is arranged between the unit compartment and the trunk edge and an outer wall is attached to the outer side of the trunk edge or an interior material is attached to the inner side of the trunk edge, the damping grid 201 is arranged instead of the earthquake-resistant panel. Since the horizontal assembly member 203 is displaced in the forward direction (or rearward direction) and coupled to the column 204b, the horizontal assembly member 203 is disposed so as to protrude a predetermined length from the outer surface of the column 204b.

In this case, the frame 309 is notched or drilled according to the shape of the lattice of the damping lattice body 1, and has a sufficiently narrow spatial space that does not impair the ability of the damping lattice. It is processed so that it can be directly applied to the partition material 4. The notched portion is devised as follows in consideration of the movement of the vertically assembled member and the horizontally assembled member during deformation. That is, as the method of attaching the end of the vertically assembled member 302, the vertically assembled member 302 moves circularly starting from one of the ends, so that it is not fixed firmly and a viscoelastic adhesive or the like is used. And By doing so, the deformation force of the vertically assembled members 302 constituting the lattice is reduced as much as possible so that deformation other than necessary is not generated. In addition, as a method of attaching the end of the horizontal member 303, the horizontal member 303 constituting the lattice moves so as to move in parallel according to the deformation of the building. And That is, the horizontal assembly member 303 constituting the lattice is not fixed firmly, but a viscoelastic adhesive or the like is used as a movable point, or a construction method of fixing only one point is adopted.

An example in which a member 408 having the function of a stud is installed on the opposite side to serve as the base of the outer wall on one side (thickness that is the same as the width of the trunk edge). is there. Not only in this case, it is also possible to use the case where the inner edge of the inner wall has a trunk edge, and the case where the inner wall side is a Japanese-style finish (with a wall). In addition, there is a sufficient clearance for the construction of the heat insulating material and the like, and the performance of the heat insulating material is not compressed and compressed.

Even in the case of such a cut-out, a desired effect can be easily obtained because the calculation method in such a case is fixed functionally.

  In this embodiment, in the said embodiment and construction example, although the vertical assembly member and the horizontal assembly member were distinguished and shown, the vertical assembly member does not necessarily need to be vertical, a vertical assembly member is made into a horizontal assembly member, The assembled member may be a vertically assembled member. In developing vibration control devices, there is a method of developing a small device attached to the joint, but there may be problems with the physical properties of the wood to which the device is attached, so that it can fully demonstrate its capabilities Don't be. In order to obtain a damping grid body having high capability, the damping grid is attached within the framework of the existing construction method, for example, the damping grid for one span of a module having a length unit of 910 mm, 1000 mm, etc. It becomes efficient by thinking in a big aspect like attaching.

Further, the elastic modulus of the rubber bodies 706a and 706b is preferably about 50 to 70% and the plastic modulus is preferably about 30% to 50% at the time of deformation, but an appropriate rate can be adopted. Furthermore, the rubber bodies 706a and b are appropriately formed with inclined surfaces. Note that the shapes of the rubber bodies 706a and 706b are examples, and a plurality of rubber bodies are combined and fitted, and arranged at the longitudinal ends of the vertically assembled member 702 so that the vertically assembled member 702 and the horizontally assembled member are arranged.
