Description

  The present invention relates to a wall surface structure of a building and a vibration control panel used for the wall surface structure.

Various proposals have been made to further improve the seismic performance of buildings.
For example, in Patent Document 1, a face material such as a fireproof board is arranged outside a wire made of a pillar of a wooden building and the like, and a viscoelastic body is interposed between them to fix it with a nail member or the like. ing. Further, in Patent Document 2, a rectangular wall body is disposed in a state where a gap is secured on at least three sides inside the frame, not on the outside of the frame as in Patent Document 1, and buffered in the surrounding gap after the arrangement. Filling the material is disclosed.

  By the way, the structure which arrange | positions a surface material on the outer side of a frame like patent document 1, and fixes between a frame and a surface material directly with a nail member has the rigidity of the surface material arranged on the wall rather than the frame which consists of a wire. There is a feature that demonstrates earthquake resistance. In addition, it is also practiced to provide seismic resistance by providing a wire having a certain deformability such as bracing inside the frame made of this wire. The deformation ability here refers to the ability to absorb energy by deformation with a certain force, and refers to an allowable deformation within a range where the deformation does not lead to destruction.

  Although all of Patent Document 1 is targeted, since a viscoelastic body is provided between the face material and the wire, a nail or the like for fixing the space between the face material and the wire before a certain deformation of the diagonal material occurs in the face material portion. Local damage (residual distortion) such as penetration will occur. The amount of deformation in the top / bottom / left / right direction differs depending on the horizontal deformation at the time of the earthquake in the face material, and uneven deformation may occur in the face material covering the outside of the frame, which may damage the nail part fixing the face material. It is a factor. Therefore, when residual strain occurs due to an earthquake or the like, it is necessary to replace the viscoelastic body at the same time when the face material is replaced. Since these face materials are firmly fixed to the wire material at fine intervals in order to contribute as an earthquake-resistant member, the nail and other fixed parts are liable to bend and deform the nail or damage the face material.

  On the other hand, in the case of a structure in which diagonal members such as braces are provided between the wire rods, the wooden building is likely to be deformed more easily than when the seismic performance is exerted on the face material. Therefore, the difference in the deformability between the face material and the wire becomes more remarkable, and the fixed portion between the face material and the wire is more likely to be damaged.

  In the case of Patent Document 1, since the viscoelastic body interposed between the frame and the face material is made of a resin component, the energy absorption performance of the viscoelastic body has a characteristic that its performance is likely to vary depending on temperature conditions. Therefore, it is desired that the viscoelastic body having such properties be attached to the side where the temperature condition is more stable than the indoor side relatively as much as possible.

As described above, in the structure in which the viscoelastic body is provided between the wire and the surface material, the wire material, the surface material, and the fixing portion thereof are considered to have a tendency to gradually decrease the degree of fixing due to a small earthquake or a slightly large earthquake.
On the other hand, the structure of Patent Document 2 can be preferably employed when the wall body is an RC structure, but is not suitable for a small-scale building such as a wooden house. That is, in the case of Patent Document 2, the wall body must be more robust than the frame, and as a result, the weight increases and the burden on the base and the beam increases. Further, in the case of Patent Document 2, since a gap is interposed between at least three sides between the frame and the wall body, a compressive force is applied to the wall body only when a certain level or more of horizontal deformation occurs. In addition, in the case of Patent Document 2, since it is a structure that bears a compressive force on the wall, the wall may be considerably thicker if it is an RC structure, but it may be a small scale such as a wooden building. Not suitable for architecture.

  In view of such a situation, the present invention absorbs energy by a member (elastic member) having an elastic ability that does not cause damage to deformation when a horizontal deformation force is generated due to, for example, an earthquake or the like. It can absorb energy through the material and maintain the seismic control effect for a long period of time, and the small scale that occurs frequently during the lifetime of the building will not be damaged by earthquakes or medium-scale earthquakes. The object of the present invention is to provide a wall structure of a building that can exhibit its damping performance many times and a damping panel that is suitably used for this wall structure. Another object of the present invention is to provide a reinforcing method capable of more effectively exhibiting the vibration control capability characteristics of the elastic member and to transmit building deformation to the entire elastic member.

The wall surface structure according to the present invention for achieving the above object is as follows.
It is characterized in that a frame material is disposed on the inner side surface of a frame such as a pillar, a beam, or a base constituting the building, and a substantially rectangular elastic member is brought into close contact with the inner side surface of the frame material.

  According to the wall structure having such a configuration, since the elastic member is not positively stopped with a nail or a hardware, damage countermeasures can be taken. In addition, since at least one surface of the elastic member is covered with a face material harder than the elastic member, when the horizontal deformation force is generated, the horizontal deformation force can be absorbed by the elastic member.

  Here, in the present invention, a plate-like face material that is slightly larger than the outer dimension of the elastic member and smaller than the inner dimension of the frame is prepared, and the surface material is brought into contact with the inner surface of the frame. It is preferable to make it adhere to the outer side of the elastic member.

  With such a configuration, when a horizontal deformation force is generated, the force can be released from the elastic member to the outer frame via the face material. Further, the deformation of the elastic member in the out-of-plane direction can be suppressed.

Furthermore, since the out-of-plane deformation of the elastic member can be constrained, the energy absorbing power of the elastic member increases. Further, the frictional force between the face material and the frame material also contributes to energy absorption.
Moreover, in this invention, it is preferable that the said face material is attached to the said frame material so that a movement in at least a horizontal direction is possible. The face material may be movable in a vertical direction with respect to the frame material.

  With such a configuration, when the frame is about to be deformed and moved due to an earthquake or the like, the joint for fixing the face member and the frame member can be relatively moved without being damaged. Further, at the initial stage of the earthquake, the face material is protected without colliding with the face material and the frame, so that the elastic member can be kept out of the plane.

  Further, according to the present invention, the face material and the frame material are movable in the horizontal direction by a combination of a long hole formed in the face material or the frame material and a screw inserted into the long hole. It is preferable that it is attached to.

With such a configuration, the face material can be attached to the frame material so as to be slidable in the horizontal direction with an easy structure.
Here, it is preferable that the movable distance of the face material in the horizontal direction with respect to the frame is 1/50 to 1/200 of the height of one frame constituting the frame.

With such a configuration, when the deformation of the building becomes too large, the face material comes into contact with the frame, so that the effect of suppressing the deformation of the frame without using the frame member or the elastic member can be exhibited.
The main surface of the face material and the elastic member may be formed by forming a convex portion on one side and a concave portion on the other side, and positioning the convex portion and the concave portion by fitting each other.

  With such a structure, the positioning between the face material and the elastic member is good, and in addition, the contact area is increased and the fitting is performed. Can be fixed. Further, since the face material and the elastic member do not have to be tied together at a nail place or the like, the cost is reduced.

Furthermore, in the present invention, it is preferable that the frame material is incorporated so that the frame material does not contact the four corners of the frame.
With such a structure, the elastic member attached to the frame member does not contact the frame or the like at the time of the earthquake, so the elastic member is not locally crushed, and the elastic member Large energy absorption by deformation of the entire surface is obtained.

Moreover, it is preferable that a viscoelastic material is interposed on a contact surface between the frame member and the face member. This further increases the friction between the face material and the frame material and increases energy absorption.
The panel according to the present invention is a panel arranged on the inner surface of a frame such as a pillar, a beam, or a foundation constituting a building,
A substantially rectangular elastic member;
A frame member disposed on at least three sides of the elastic member, and disposed in close contact with the inner surface of the frame;
It is comprised from the flat surface material attached to the said frame material so that a movement at least in the horizontal direction was possible.

If it is such a panel, it can be effectively used as a vibration control panel for, for example, a wooden building, a small frame, and a workpiece.
Here, it is preferable that the frame member and the face member are attached to be movable at least in a horizontal direction by a long hole and a screw member inserted through the long hole.

With such a configuration, the face material can be easily moved in the horizontal direction with respect to the frame material, so that one of the problems, such as the face material and the frame material fixture (such as nails), is damaged. do not do.
In the present invention, it is preferable that a viscoelastic member is interposed on a contact surface between the frame member and the frame.

  Thus, if the viscoelastic body is interposed on the joint surface that rubs against the frame material, the vibration control performance of the building can be improved.

  According to the wall surface structure of a building according to the present invention, energy can be absorbed by the elastic member disposed in the internal space of the frame via the frame material. Furthermore, the frictional force between the face material and the frame material also contributes to energy absorption. Further, even when energy is absorbed, it is not damaged. Further, since the elastic member is fixed in close contact with the frame member, there is no risk of damage due to an earthquake or horizontal movement.

In the early stage of the earthquake, the face material is protected without colliding with the face material and the frame, so that the elastic member can be received while being restrained out of the plane.
Furthermore, when a face material that is slightly smaller than the size of the frame is attached to the frame material so as not to contact the frame, a load can be received by this face material in the event of an earthquake that causes a horizontal moving force.

  Moreover, if the face material is attached so as to be movable in the horizontal direction with respect to the frame material, the face material moves in the horizontal direction inside the frame when an earthquake occurs, and the face material restrains the elastic member. Moreover, the deformation of the frame can be prevented by the face material by the frictional force between the face material and the frame material.

  As described above, in the present invention, energy can be absorbed without damaging the elastic member and the face material that restrains the elastic member at the time of the occurrence of an earthquake. It can be demonstrated.

  In addition, according to the vibration control panel of the present invention, the wall surface structure as described above can be easily formed. In addition, in a small earthquake that occurs over a long period of time in which a building exists, the panel is not damaged, and effectively works as a panel having two different objects (an elastic member and a viscoelastic body).

Embodiments of the present invention shown in the drawings will be described below.
FIGS. 1-6 shows the wall surface structure of the building by one Example of this invention, and shows the example applied especially to the wooden building.

  In the wall surface structure of the present embodiment, as shown in FIGS. 1 to 3, a base 4 is provided on the foundation 2, and pillars 6 such as through pillars, tube pillars, and studs are arranged at regular intervals on the base 4. It is provided for each. In addition, braces 8 are passed to these columns 6. In addition, you may provide two this bracing 8 so that it may cross | intersect not only one. In the present embodiment, a vibration control panel 20 described below is fitted in a space in a frame of a quadrangular frame F composed of two pillars 6 and 6, a base 4, a beam (not shown) and the like.

  The seismic control panel 20 only needs to have the elastic member 22 fitted in the frame member and the surface member in contact with the elastic member 22 so as to cover the elastic member 22, but as shown in an exploded view in FIG. The elastic member 22 made of the above-mentioned foamed synthetic resin, the frame members 24a, 24a, 24b, 24b disposed on the top, bottom, left and right edge surfaces of the elastic member 22, and either the indoor side or the outdoor side of the elastic member 22 are opposed to each other. It is comprised from the flat surface material 26 arrange | positioned. The height S and the width P of the face material 26 are preferably formed to be slightly larger than the height L and the width M of the elastic member 22. In short, the face material 26 may be disposed so as to face the elastic member 22 and be disposed in the frame of the frame F.

  The elastic member 22 only needs to have elasticity equal to or higher than that of wood, but is preferably formed of, for example, a foamed synthetic resin heat insulating material, wood, or the like, specifically, hard foam polystyrene, hard foam Polyurethane, foamed polypropylene and the like are suitable. Of these, beads expanded polystyrene, beads expanded polypropylene and the like are particularly suitable.

The pair of frame members 24a and the pair of frame members 24b are arranged on the center side of each side so as not to contact the corners of the frame F. These frame members 24a and 24b are formed of a steel member, plastic, wood, or the like, but are preferably made of wood. Further, the frame members 24 a and 24 b are slightly narrower than the width of the base 4. As described above, the frame members 24a and 24b are formed to be slightly narrower than the base 4 so that the frame member 24a is placed on the base 4 or the frame member 24b is placed along the pillar 6. In this case, the frame member does not protrude from the base 4 or the column 6 in the width direction. Of these frame members 24a and 24b, the pair of frame members 24a arranged on the short side of the elastic member 22 have, for example, long holes 25a that are long in the horizontal direction at both ends. On the other hand, long holes 25b and 25b are also formed in the pair of frame members 24b arranged on the long side of the elastic member 22. The number of the long holes 25a and 25b formed in the frame members 24a and 24b is not limited to the embodiment.

  The face material 26 is formed of a plate material having an appropriate strength such as a structural plywood. The face material is preferably a wooden material, but an iron plate, a lightweight concrete plate or a gypsum board can also be used. In the face material 26, long hole-like screw insertion holes 27 are formed at positions corresponding to the long holes 25a, 25b of the frame members 24a, 24b. Further, the height (longitudinal length) S and the width (lateral length) P of the face member 26 made of structural plywood or the like is made slightly larger than the height L and width M of the elastic member 22. ing. Further, the height S and the width P of the face material 26 are smaller than the inner dimensions (height T and width U) of the frame F shown in FIG.

  Then, a substantially L-shaped gap 32 is secured at the corner of the frame F as shown in FIG. By securing the width V of the gap 32, the face material 26 is fitted into the frame without being in contact with the frame F as shown in FIG. . The width V of the gap 32 indicates the distance in which the face member 26 can be moved in the horizontal direction. The width V is 1/50 to 1/200 of the frame height constituting the frame F, preferably It is desirable that it is 1/100 to 1/200. If the width V is set at such a ratio, the frame can be restrained in a balanced manner during horizontal deformation. Moreover, since the face material 26 contacts the frame F when the building deformation becomes too large, an effect of suppressing the deformation without the frame deformation can be expected.

On the other hand, the elastic member 22 and the frame members 24a, 24a, 25b, and 25b may be integrated or may be incorporated at the site.
Further, in the face member 26 and the frame members 24a and 24b, the screw members 34 are respectively inserted between the long holes 25a and the screw insertion holes 27 constituting the cross shape. Thereby, the face material 26 is installed so as to be movable at least in the horizontal direction with respect to the horizontal members such as the base 4 and the beam 30.

Further, it is preferable that a viscoelastic body 37 is interposed between the four surrounding frame members 24a and 24b and the face member 26 as shown in FIG. 6 which is an enlarged view of the Y portion in FIG. . By interposing the viscoelastic body 37 in this manner, even when the periphery of the screw member 34 is loosened, the viscoelastic body 37 can be deformed by utilizing the relative displacement between the face member 26 and the frame member 24a. it can. Thereby, even if it is a small vibration, the outstanding damping performance can be exhibited. These viscoelastic bodies 37 are preferably interposed not only in the horizontal frame members 24a and 24a but also in the vertical frame members 24b and 24b.
The seismic control panel 20 according to one embodiment of the present invention is formed as described above. However, when these seismic control panels 20 are assembled in a wall of a building, two horizontal members and 2 What is necessary is just to insert in the space between the vertical members of a book. In this case, since the face member 26 is attached to the frame F via the frame members 24a and 24b, no part contacts the frame F. Further, the elastic member 22 does not come into contact with the corners of the frame F.

  In this embodiment, if the elastic member 22 does not come out of the frame surrounded by the upper, lower, left and right frame members 24a and 24b, even if there is a clearance between the frame members 24a and 24b and the face member 26, You may push in and form the face material 26 slightly larger than the magnitude | size inside the frame defined by frame material 24a, 24b.

In this way, when the seismic control panel 20 is installed in the frame F, if an earthquake occurs and a horizontal movement force is generated in the frame F, the face material 26 with respect to the surrounding four frame members 24a, 24a, 24b, and 24b. Move relatively horizontally. Then, the face material 26 comes into contact with the inner surface of the column member 6 in the moved direction. That is, if the beam 30 of the frame F moves relative to the right as shown in FIG. 7 from the posture of FIG. 3, the vibration control panel 20 approaches the columns 6 and 6 at the upper left corner and the lower right corner. To do. Thereby, since the face material 26 of the vibration control panel 20 is pressed by the base 4 and the beam 30, the face material 26 suppresses deformation of the wall due to the rigidity of the entire surface. In addition, the compressive force at this time can be dispersed and released to surrounding frames such as columns, foundations, and beams via the elastic member 22, the face material 26, and the frame members 24a and 24b. Further, since the corner portion of the elastic member 22 does not come into contact with the frame F, the corner portion is not damaged or is not locally deformed.

  In this way, in this embodiment, energy can be absorbed through the face material 26 for relatively large horizontal deformation. Thereby, the deformation of the frame F can be suppressed. Further, it is possible to prevent the elastic member 22 and the face material 26 from being damaged as much as possible when energy is absorbed.

As mentioned above, although one Example of this invention was described, this invention is not limited to the said Example at all.
For example, in the above-described embodiment, the surface material 26 and the elastic member 22 are not simply opposed to each other by a flat surface, but the concave and convex fitting portions are formed on the main surfaces facing each other as shown in FIG. It can also be provided. That is, in FIG. 8, a convex portion 36 is formed on the surface of the face material 26, and a concave portion 38 corresponding to the convex portion 36 is formed in the elastic member 22. The recess 38 may be a through hole 38.

  If it does in this way, mutual positioning can be made easy by fitting the convex part 36 of the face material 26, and the concave part 38 of the elastic member 22. FIG. A viscoelastic body 37 is preferably interposed on the surface of the convex portion 36. Moreover, the face material 26 can also be arrange | positioned at the both sides of the elastic member 22, as shown in FIG. Thus, if the elastic member 22 is clamped from both sides, the elastic member 22 can be firmly integrated by the pair of face members 26 and 26, and the vibration control performance of the elastic member is further enhanced. Further, in FIG. 8, an uneven fitting portion can also be provided between the face material 26 arranged on the front side (left side) of the paper surface and the elastic body 22.

  Moreover, the shape of the convex part 36 of these face materials 26 and the hole 38 of the elastic member 22 is not limited to the linear shape shown in FIG. 8, FIG. 9 (A), (B), (C), (D As shown in (), each may be a cross, a corner, a circle, or a combination of plus and minus.

  Further, when the face members 26 are arranged on both sides of the elastic member 22, one of the face members 26 is not substantially the same shape as the elastic body 22, as shown in FIGS. You can also. In other words, in FIG. 10, one face material 26 ′ is disposed obliquely with respect to the elastic body 22 in a brace shape. In FIG. 11, one face material 26 ″ is approximately half the size of the elastic member 22. In FIG. 12, the face material is composed of four triangular elements 40 having only corner portions. In FIG. 12, a face material is constituted by four triangular elements 40. In this case, as shown in FIG. 13, the triangular element 40 may be attached with a small gap W secured between the horizontal member such as the beam 30 and the vertical member such as the column 6.

  Furthermore, as shown in FIG. 14, when the face members 26, 26 are arranged on both sides of the elastic member 22, the shape of the frame members 24a, 24b arranged on the end surface of the fore edge is convex, and a screw is added to this. The member 34 may be attached. In this case, however, the screw insertion holes formed in the horizontal frame members 24a and 24b are preferably long holes.

Such a vibration control panel 20 is naturally applicable to the first floor or the second floor or more of a building. Further, the present invention can be applied to a partition wall between rooms or a wall around an opening.
In the above embodiment, the face member 26 is movable in the horizontal direction with respect to the upper and lower frame members 24a and 24a, but may be movable in the vertical direction with respect to the left and right frame members 24b and 24b. good. In short, it is only necessary that the face material 26 is movable in the horizontal direction.

  In the above embodiment, the viscoelastic body 37 is interposed between the frame members 24a and 24b and the face material 26 corresponding thereto, but the viscoelastic material is interposed between the frame members 24a and 24b and the frame F. Can also be interposed. Alternatively, a viscoelastic body 37 can be interposed between the frame members 24 a and 24 b and the elastic member 22.

  The present invention can be effectively applied to wooden houses, but can also be applied to other than wooden buildings. In the case of a wooden house, a foamed synthetic resin is used as the elastic member 22, and a structural plywood or the like stronger than the foamed synthetic resin panel is applied as the face member 26. It is also possible to use a plaster board or the like, and a concrete plate or a steel plate as the face material 26. In short, the present invention can be applied if the face member 26 has a relatively high hardness relative to the elastic member 22.

Moreover, although the bracing 8 is provided in the said Example, it is applicable also to the wall surface in which this bracing 8 does not exist.
Further, when the damping panel 20 is fitted into the frame F, as shown in FIG. 15, for example, a positioning projection 42 is provided on the frame member 24a and the like, and the projection is locked to the beam 30 or the like. The concave portion 44 is provided, and the combination of these can facilitate the positioning of the frame material.

The frame members 24a and 24b may be in contact with each other at the four corners of the elastic member 22, but the frames 24a and 24b are preferably separated from each other so as not to be touched during horizontal deformation.
Furthermore, in the above embodiment, gaps are formed at the four corners of the frame F, and there is a possibility that the heat insulation of this part may be partially impaired. To improve this, separate elastic members are provided at the four corners that become the gaps. It suffices to fit, and thereby sufficient heat-insulating and air-tight performance can be obtained.

  Further, the present invention can be applied not only when newly constructing a house, but also when renovating an existing house to improve seismic performance, or when performing an extension or reconstruction.
