The bottom plate 15 is provided with a communication hole 17 that is aligned with the center of the guide groove 12, and the side plate 16 is provided with a fitting projection 18 that is locked in the fitting groove 13.
[0032]
The body member 3 is inexpensive and widely used as a building material in this embodiment, and is a lightweight section steel with a lip groove cross section because the interior material 5 can be easily attached with self-drilling screws. Although it is possible to adopt a form using synthetic resin material, in this case, the body side and the interior material side and the wall panel side are connected via the body edge member and the seismic isolation connecting member. The heat bridge or the cold bridge transmitted between them can be cut off, and the heat insulation effect can be further enhanced.
[0033]
The seismic isolation member 2 is provided with a press-fitting guide surface 19 formed of an arcuate surface between the fitting groove 13 and the locking piece 14 of the body edge locking plate 11, and a body formed by fitting projections 18.

Attach to
[0035]
When the head side of the anchor bolt 20 is attached to the seismic isolation plate 10 with the nut 24, the spacer 21 keeps an interval so that the washers 22 and 23 do not press against the opening edge of the guide groove 12. The seismic isolation connecting member 4 is configured to be rotatable and horizontally slidable with respect to the groove 12. In this embodiment, the spacer 21 is thicker than the seismic isolation plate 10 and has an outer diameter smaller than that of the guide groove 12 as the spacer 21. Spring washer is used.
[0036]
In this embodiment, the spring 21 is used as the spacer 21 to prevent the seismic isolation connecting member 4 from being loosened with respect to the seismic isolation plate 10. However, as the spacer 21, a metal or resin flat washer having good slidability or the like is used. A collar may be used, and if it is necessary to prevent loosening, a spring washer may be mounted between each washer 22, 23 and the head or nut 24 of the anchor bolt 20.
[0037]
Thereby, the seismic isolation receiving member 2 and the body edge member 3 are detachably connected to each other, so that the seismic isolation receiving member 2 is slidable with respect to the body edge member 3 and is isolated from the seismic isolation receiving member 2. The seismic connection member 4 is configured to be rotatable and slidable, and the wall panel 6 connected to the other side of the seismic isolation connection member 4 is rotatably and slidably connected to the body member 3 and the interior material 5. Will be.
[0038]
In the illustrated embodiment, since the waist edge member 3 is used as a vertical waist edge, the seismic isolation receiving member 2 can be vertically slid with respect to the waist member 3, and the seismic isolation receiving member 2 is also freed up. The seismic connection member 4 is configured to be rotatable and horizontally slidable, and the wall panel 6 connected to the other side of the seismic isolation connection member 4 is rotatable and horizontally and vertically slid with respect to the waist member 3 and the interior material 5.

Since the seismic isolation mounting 1 is composed of a small number of components having a simple structure, it can be provided at low cost, and the seismic isolation wall structure using the seismic isolation mounting 1 can be used as a seismic isolation connecting member. The other side of 4 is buried in the wall panel 6, and a simple seismic isolation wall can be constructed by a simple operation of attaching the interior material 5 to the waist member 3.
[0040]
In this embodiment, an ALC (lightweight cellular concrete) panel is used for the wall panel 6. However, in the case of a fragile wall panel 6 such as an ALC panel, an anchor portion of the seismic isolation connecting member 4 embedded in the wall panel 6 is used. (Screw shaft of the anchor bolt 20) may fall off. Therefore, in order to increase the anchor support force, the tubular buried holding member 8 provided with a retaining prevention means on the inner and outer circumferences is buried. When a supporting force can be obtained, the embedded holding member 8 can be omitted.
[0041]
Various known buried holding members that function similarly can be used as the buried holding member 8. However, the buried holding member 8 can be easily inserted into the ALC panel as the wall panel 6, and the ALC panel and the seismic isolation connecting member can be used. It is desirable to use a nylon anchor plug having a strong adhesive force to the anchor portion 4 and excellent pull-out strength, for example, Fisher Plug (trade name) of Minegishi Co., Ltd.
[0042]
In addition, urethane foam or other known plate-shaped heat insulating materials can be used as the plate-shaped heat insulating material 7, but the heat insulating performance is high and the flame-retardant property is provided, and the anchor portion of the seismic isolation connecting member 4 is pressed. Insulation materials made of phenolic resin foam and attached to the front and back surfaces with a polyester nonwoven fabric attached to the surface material, such as Neomafoam (trade name) of Asahi Kasei Kogyo Co., Ltd. desirable.
[0043]
Next, the construction procedure of the seismic isolation wall structure using the seismic isolation mounting 1 will be described with reference to FIGS. 3 to 5. An upper beam member (girder) on which a wall panel 6 such as an ALC panel previously produced at a factory is constructed on site. 25 and a lower beam member (base) 26 and a frame formed by left and right column members (not shown) are mounted in a state where the upper and lower sides are supported so as to be capable of in-plane deformation or interlayer displacement.
[0044]
The support structure that enables the in-plane deformation or interlayer displacement of the wall panel 6 and the seal structure at the joint between the wall panels 6 employ various conventionally known configurations as appropriate, and thus illustration and description are omitted. In the illustrated embodiment, the beam members 25 and 26 are made of H-shaped steel, and a floor concrete 27 is mounted on the beam member 26 and a ceiling material (not shown) is mounted on the beam member 25. I do.
[0045]
As shown in FIG. 3A, the plate-shaped heat insulating material 7 is superimposed on the wall panel 6 from the back side and temporarily fixed by a fixing means such as a nail 28, and then a positioning jig is applied to the plate heat insulating material 7. In this way, ink is drawn out at the position of the communication hole 17 and a mounting hole 29 is drilled in the plate-like heat insulating material 7 and the wall panel 6 with a drill or other drilling tool, but as a positioning jig as shown in FIG. The body member 3 can be used, and no special positioning jig is required.
[0046]
4A, a positioning nut 32 is screwed into a predetermined position with respect to the screw shaft 31 as shown in FIG. 4A, and a fixing nut 34 is screwed through a stopper washer 33. Using the jig 30, the embedded holding member 8 is attached to the tip end side of the screw shaft 31, and the embedding jig 30 is pressed to press the embedded holding member 8 into the mounting hole 29, and at that time, the electric rotating is performed if necessary. The embedding jig 30 is rotated with a tool.
[0047]
As a result, the buried holding member 8 is buried at a predetermined position in the wall panel 6 at a predetermined depth, and a communication hole 35 that fits the positioning nut 32 is formed in the plate-like heat insulating material 7. In this configuration, the length of the positioning nut 32 is made to match the thickness of the plate-shaped heat insulating material 7, and the burying jig 30 is pulled out after the burying holding member 8 is installed.
[0048]
Thereafter, as shown in FIG. 4B, the anchor bolt 20 of the seismic isolation connection member 4 having the head side connected to the seismic isolation receiving member 2 is inserted into the buried holding member 8 with a fastening tool such as an impact wrench. Then, the seismic isolation receiving member 2 and the plate heat insulating material 7 are simultaneously attached to the wall panel 6 using the seismic isolation receiving plate 10 as a pressing member for the plate heat insulating material 7.
[0049]
In the illustrated embodiment, a general-purpose and inexpensive short nut is used for the nut 24, and the lower side of the communication hole 35 provided in the plate-shaped heat insulating material 7 remains hollow. It is also possible to use a long nut similar to the nut 32 and to embed the nut in the entire area of the communication hole 35, thereby enhancing the effect of reinforcing the seismic isolation connection member 4 and preventing it from falling off.
[0050]
The seismic isolation receiving member 2 is connected to the rim member 3 and the interior material 5 is attached thereto, whereby the seismic isolation wall structure shown in FIG. 1 using the seismic isolation attachment 1 is obtained. As shown in FIGS. 5 and 6, a number of seismic isolation fittings 1 are attached at predetermined intervals along the vertical and horizontal directions, and the interior material is straddled over each of the waist members 3 (vertical waist edges) arranged vertically. 5 (plaster board) is attached.
[0051]
In the illustrated embodiment, for example, an interior material 5 (gypsum board) having a width of 1820 mm is arranged in parallel, and a wall panel 6 (ALC panel) having a width of 606 mm is arranged on the front side thereof. The two are arranged so as to be shifted from each other at the joint portion, and three wall panels 6 are connected to one interior material 5 via the seismic isolation fitting 1 so as to be seismically isolated due to the dimensional difference between the two.
[0052]
When the fitting protrusion 18 of the side plate 16 is pressed against the press-fitting guide surface 19 of the body locking plate 11, the side member 16 expands and the fitting protrusion 18 fits into the fitting groove 13. Has a large pressing force when it is simultaneously mounted on the seismic isolation members 2 arranged at a predetermined interval along the column. When the fitting projection 18 is fitted in the groove 13 and the fitting projection 18 is pressed against the other press-fitting guide surface 19, mounting can be easily performed with a relatively small pressing force.
[0053]
When the body member 3 is mounted, the front end side of the seismic isolation connection member 4 is visually observed from the communication hole 17 provided in the bottom plate 15, and the body member 3 is vertically slid after being mounted in a roughly positioned state. By doing so, fine adjustment in the height direction can be performed, and the locking piece 14 of the body edge locking plate 11 abuts against the bottom plate 15 of the mounted body edge member 3 to prevent deformation and reinforce. .
[0054]
Further, when the interior material 5 such as a gypsum board is attached to the back surface of the waist member 3, the wall panel 6 and the interior material 5 may not be arranged in parallel. It is necessary to adjust the front and rear position by operating the seismic isolation connection member 4 that has been set, so as to eliminate the unevenness of the body edge member 5.
[0055]
The front and rear position adjustment is performed by inserting a screwdriver or the like through the communication hole 17 of the body edge member 3 and rotating the anchor bolt 20 of the seismic isolation connecting member 4 in the tightening direction. The anchor portion of the anchor bolt 20 is embedded in the wall panel 6. The seismic isolation receiving plate 10 rotates in the holding member 8 and the seismic isolation receiving plate 10 moves the seismic isolation receiving member 2 and the body edge member 3 forward while compressing the plate-like heat insulating material 7. 15 Make the outer surface free from unevenness, and attach the interior material 5.
[0056]
In the illustrated embodiment, a communication hole 17 is formed in advance in the waist edge member 3 for adjusting the position in front and rear with respect to a position suitable for the seismic isolation connection member 4, and this communication hole 17 is used. Although the body edge member 3 is also used as a positioning jig, it is also possible to adopt a form in which post-processing is performed only on a portion that requires front and rear position adjustment.
[0057]
6A shows a steady state, FIG. 6B shows a seismic isolation state when subjected to seismic force or the like, and FIG. The connecting member 4 is located substantially at the center of the guide groove 12 and supports the wall panel 6 and the plate-like heat insulating material 7, whereby the interior material 5 and each wall panel 6 stand upright. In addition, the shape and operation of the seismic isolation attachment 1 are exaggerated for ease of explanation.
[0058]
Further, in the seismic isolation state shown in (b), the interior material 5 attached to the rim member 3 is temporarily deformed due to the restraint on the skeleton side, but is restored to an upright state due to cancellation of seismic force and the like, and Each of the wall panels 6 attached via the seismic mounting fixtures 1 has a tilt angle θ within the allowable range of the joint part because each seismic isolation mounting fixture 1 performs a seismic isolation operation by rotating and sliding according to seismic force or the like. To be deformed.
[0059]
That is, in each seismic isolation mounting 1, each wall panel 6 supported by the seismic isolation connecting member 4 rotates and horizontally slides through the guide groove 12 provided in the seismic isolation receiving member 2, and the body edge member 3 and the interior The seismic isolation operation is performed according to the seismic force without receiving the interference of the material 5, so that the wall panel 6 and the interior material 5 can be prevented from being damaged, and the simple structure has a stable seismic isolation effect even for long-term use. Can be expected.
[0060]
Further, after the seismic force or the like is eliminated by the attachment / detachment structure of the body rim member 3 with respect to the seismic isolation receiving member 2, the body rim member 3 and the interior material 5 are once removed, and the seismic isolation connecting member 4 is substantially centered on the horizontal guide groove 12. It is easy to re-adjust each seismic isolation mounting 1 so that it is located at a position, and restore each wall panel 6 to an upright state, and this detachable structure is also useful for repair and dismantling work.
[0061]
Note that the present invention is not limited to the illustrated embodiment, and can adopt various modifications within the scope of the gist. For example, in the illustrated embodiment, the plate-shaped heat insulating material 7 is used for the heat insulating member, and the interior material is used. Although it was installed between the seismic isolation member 3 and the wall panel 6 in the space 9 formed between the wall member 6 and the wall panel 6 (external heat insulation), it was installed between the body edge member 3 and the interior material 5 (internal heat insulation). Embodiments can also be employed.
[0062]
Further, an embodiment in which glass wool or other irregular heat insulating material is used as a heat insulating member instead of the plate-shaped heat insulating material 7 to fill the space 9 on both sides of the seismic isolation receiving member 2 and the body edge member 3 or a heat insulating member It is also possible to adopt an embodiment in which only the space 9 is provided without using the space 9. When a heat insulating structure using a heat insulating member is not required, it is also possible to adopt a configuration including only the space 9.
[0063]
Further, in the illustrated embodiment, the body members 3 are arranged in a vertical state and are installed between the beam and the base and used as a vertical body edge. However, the body members 3 are arranged in a horizontal state and adjacent columns. The seismic isolation receiving member 2 is slidably connected to the horizontal body edge so as to be horizontally slidable, and the seismic isolation connecting member is provided in a guide groove 12 (which becomes vertically long) provided in the seismic isolation receiving member 2. 4 may be connected so as to be rotatable and vertically slidable.
[0064]
In the case of the embodiment using the horizontal waist edge, the horizontal sliding of the waist edge member 3 and the seismic isolation receiving member 2 and the guide groove 12 of the seismic isolation connecting member 4 against the seismic force in the horizontal direction are performed. In addition to performing the seismic isolation operation by rotation, it is possible to respond to vertical seismic force by performing seismic isolation operation by rotation and vertical sliding in the guide groove 12 of the seismic isolation connection member 4.
[0065]
Therefore, the seismic isolation mounting device 1 can be used for both the vertical waist and the horizontal waist only by selecting whether the waist edge member 3 is used in a vertically long state or vertically used or horizontally used in a horizontal state. Therefore, the degree of freedom in structural design is expanded, and by using common parts, effects such as cost reduction and easy part management can be obtained.
[0066]
Next, the seismic isolation wall structure according to the second embodiment will be described with reference to FIG. 7. Particularly, focusing on the differences from the first embodiment, the cross-sectional shape of the base 36 for mounting the seismic isolation connecting member will be described. In the horizontal plane, mounting holes 38 are provided at the left and right ends, and mounting screw holes 39 are provided at the center, and a pressing blade mechanism 37 is provided below the vertical surface. .
[0067]
The seismic isolation connecting member mounting base 36 can be easily pushed into the plate-like heat insulating material 7 and inserted. After insertion, the base 36 is fixed to the wall panel 6 by the anchor member 41 through the mounting holes 38 at both right and left ends. In the embodiment, it is not necessary to make a prepared hole with a drill or the like as in the first embodiment, and the anchor member 41 can be easily fixed to the wall panel 6 using a text driver or the like.
