A possible preferred embodiment of the present invention will be described in detail with reference to the drawings. In addition, the drawing reference reference numerals added to the following description are added to each element for convenience as an example for assisting understanding, and the present invention is not intended to be limited to the illustrated embodiment. Further, in the drawings, it is mainly used to explain the positional relationship of each component, and the contact relationship and the cross-sectional shape of each component are not shown accurately.

First, as an outline of the present invention, a concrete example of an earthquake-resistant reinforcing structure applied to a partition of a large hall in a cultural property building will be described. As shown in FIG. 1, the seismic-resistant reinforcing structure includes fittings 10a and b and stopper means 20a and b. The fittings 10a and 10b are exemplified as, for example, sliding doors and shoji screens, and are installed in the openings defined by the sill material 30, the lintel material 40 and the two pillar materials 50a and b. Here, the fitting 10a is installed in close contact with the left pillar 50a, and the fitting 10b is installed in close contact with the right pillar 50b. Further, the stopper means 20a and b prevent the fittings 10a and b from sliding on the sill material 30. The fittings 10a and 10b have the same symmetrical structure, and the stopper means 20a and 20b also have the same symmetrical structure.

The stopper means 20a includes a first guide member 21, a second guide member 22, and a stopper pin 23. The first guide member 21 is provided at the lower corner portion of the fitting 10a on the side opposite to the pillar member 50a on the left side, in other words, at the lower right corner portion of the fitting 10a. Further, the second guide member 22 is provided on the threshold member 30 at a position corresponding to the first guide member 21, in other words, at a position between the pillar members 50a and b and away from the pillar members 50a and b. The stopper pin 23 is inserted into the first guide member 21 and the second guide member 22 over both guide members. The stopper pin 23 is configured to prevent the fitting 10a from sliding when it is inserted into the first guide member 21 and the second guide member 22.

In such a seismic-resistant reinforcing structure, when a horizontal force is applied from the left side to the right side (in the direction of the arrow) due to rolling, the fitting 10a is pressed by the left column member 50a. Since the stopper member 20a prevents sliding to the right side, the stopper member 20a rotates clockwise around the stopper member 20a, and the upper left corner of the fitting 10a is pressed against the lintel 40. As a result, the fitting 10a receives a compressive force between the upper left corner and the lower right corner as shown in the figure. At this time, the fitting 10a exerts a function as a compression brace, and brings earthquake resistance due to a reaction force (resistance force) to the compression force to the cultural property building.

On the other hand, the fitting 10b rotates clockwise like the fitting 10a. At this time, the fitting 10b does not function as a tension brace. However, contrary to the case of FIG. 2, when a horizontal force is generated from the right side to the left side, the fitting 10b exerts a function as a compression brace in the same manner as the fitting 10a, and brings earthquake resistance to the cultural property building.

As described above, in the earthquake-resistant reinforcing structure of the present invention, the fittings 10a and 10b are made to exert the function as the compression brace. In other words, the seismic reinforced structure of the present invention does not expect tensile stress due to general tension braces (braces) or shear stress due to general bearing walls. Further, in the present installation form, the fittings 10a and 10b provide the cultural property building with earthquake resistance due to the reaction force against the compressive force with respect to the horizontal force in one direction, but with respect to the horizontal force in the opposite direction. Does not exhibit earthquake resistance. Such an earthquake-resistant reinforcing structure has a demerit from the viewpoint of earthquake-resistant reinforcement, but on the other hand, it is not necessary to provide bolt holes for fixing to the column members 50a and b, which is a cultural property. It also has the great advantage of not damaging the pillars of buildings that have traditional preservation value.

Hereinafter, a possible preferred embodiment of the present invention based on the above outline will be described with reference to a specific example. In the following embodiment, the fittings 10a and 10b having the shoji-like structure shown in FIG. 3 will be applied as the partition of the hall in the cultural property building as in the above outline. In the present application, each part of the shoji-like structure is referred to as shown in the figure. That is, the shoji-like structure includes an upper rail, a middle rail, a lower rail, and a vertical rail as a general frame, and these parts are collectively referred to as a stile portion. The stile has an inwardly protruding attachment (chili). This attachment is originally an overhanging part to which shoji paper is attached. A horizontal child and a vertical child are passed to the inside of the stile to form a lattice shape. Yokoko and vertical are also collectively referred to as the lattice part (kumiko). The part corresponding to the shoji paper is called the shoji part. The fittings 10a and 10b may be not only the type of shoji with a waist as shown in FIG. 3, but also the type of a water shoji without a waist. Further, the plate-shaped member may be formed without arranging the lattice portion on the waist.

[Embodiment 1]
In the first embodiment, fittings 10a and 10b having a combined structure (also referred to as a plywood structure) of a layered member or a frame member will be described.

[Structure of fittings 10a and 10a]
The fittings 10a and 10b of the first embodiment have a structure in which two lattice plates are sandwiched between two frame frame plates and a shoji plate is further sandwiched between the two lattice plates. As shown in FIG. 4A, the lattice plate is a frame formed by welding an elongated stainless steel plate. As shown in FIG. 4B, the lattice plate is, for example, a single rigid material plate (for example, a rigid metal, preferably a stainless steel plate) obtained by cutting out a lattice window by laser processing. Since the lattice plate has a portion to be attached, the width of the outer frame is wider than that of the lattice plate. As shown in FIG. 4C, the obstacle plate has a transparent plate panel (preferably a high-strength resin plate, for example, a polycarbonate resin as a core material, and the polycarbonate resin is sandwiched between glass plates) inside a frame serving as a frame. It has a flat plate structure in which a polycarbonate resin plate) is fitted. Both sides of the polycarbonate resin plate are covered with glass plates. In FIG. 4C, the polycarbonate resin plate is colored to distinguish it from the window portion, but is actually transparent.

The fittings 10a and 10b are constructed by sticking such two frame frame plates, two lattice plates and one shoji plate as shown in FIG. 5 and joining them with bolts. The lattice plate may be bent during laser processing of the lattice window. In that case, it is preferable to arrange so that the deflection (convex surface) faces the shoji board (in other words, faces inward).
[Structure of stopper means 20a, b]
As shown in FIG. 6, the stopper means 20a and b of the first embodiment include an L-shaped metal fitting as the first guide member 21, a pipe as the second guide member 22, and a stopper pin 23. The first guide member 21 has a surface that comes into contact with the side surfaces of the fittings 10a and 10b, and a surface that extends along the sill material 30. The second guide member 22 penetrates the threshold material 30 and reaches into the base. One end of the stopper pin 23 is connected to the first guide member 21, for example, by screwing, and the other end is inserted into the second guide member 22. The first guide member 21, the second guide member 22, and the stopper pin 23 are made of stainless steel, steel, wood, fiber reinforced plastic, or the like, but are made of a rigid material because they serve as fulcrums of the reaction force against the compressive force. Is preferable. Further, a reinforcing plate may be provided between the first guide member 21 and the sill material 30 to reinforce the sill material 30.

[Structure of gap adjusting material 60]
In the first embodiment, the gap adjusting material 60 that fills the gap between the fittings 10a and 10b and the lintel material 40 is arranged. The gap adjusting material 60 is, for example, a stainless steel plate, and as shown in FIG. 7, is arranged along the kamoi material 40 at the upper corner portion defined by the pillar material 50a and the kamoi material 40. The gap adjusting member 60 may be formed into an L shape, and one end thereof may extend downward along the pillar members 50a and 50a. In this way, the shear pressure on the Kamoi material 40 from below is relaxed. The gap adjusting material 60 can be fixed to the pillar material 50a and / or the Kamoi material 40, but even when it is fixed, the pillar material 50a and / or the pillar material 50a and / or the pillar material 50a are tied with a wire, for example. It is desirable that the style does not damage the Kamoi material 40.

It is preferable to cover the frame frame plate, the lattice plate, the shoji material, the first guide member 21, and the gap adjusting material 60 with, for example, a decorative plate so as not to spoil the landscape of the cultural property building. Further, the shoji material may be covered with paper.

[Structure of cultural property building]
In the first embodiment, the fittings 10a and 10b are installed in the opening defined by the sill material 30, the lintel material 40 and the two pillar materials 50a and b, as in the above outline. In the present invention, a hole for attaching the second guide member 22 is provided only to the sill material 30, and no treatment is applied to the lintel material 40 and the two pillar materials 50a and b. Since the threshold material 30 is a member that wears and deteriorates after many years of use, it is a member that is appropriately replaced even if it is a cultural property building. Therefore, even if a hole is provided in the threshold material 30, there is no problem in terms of preservation of the cultural property building.

[How to install fittings 10a and 10a]
The fittings 10a and 10b are installed by inserting the upper side into the groove provided in the lintel 40 and then inserting the lower side into the groove provided in the sill material 30, similarly to a general shoji. In this state, the fittings 10a and 10b can slide on the sill material 30 in the same manner as a general shoji.

Next, the fittings 10a and b are moved so as to be in close contact with one of the pillar members 50a and b, that is, the fittings 10a and b are moved to the left and right ends. At this time, the gap adjusting material 60 is arranged at the upper corner portion defined by the pillar materials 50a and b and the lintel material 40, and the gap adjusting material 60 is sandwiched between the fittings 10a and b and the lintel material 40. , Fill the gap between the fittings 10a and 10a and the lintel 40.

Then, the stopper pin 23 is inserted into the second guide member 22 with the fittings 10a and 10b brought close to the left and right ends. In this state, even if the fittings 10a and b try to slide on the sill material 30, the fittings 10a and b come into contact with the first guide member 21 and the sliding is prevented.

By pulling out the stopper pin 23 from the second guide member 22, the fittings 10a and 10b can be slidable again.

[Effect of Embodiment 1]
As described above, the fittings 10a and b of the first embodiment are installed without any treatment on the lintel 40 and the two pillars 50a and b. Therefore, it is advantageous from the viewpoint of preserving cultural property buildings.

Further, in the first embodiment, the gap adjusting material 60 is used to fill the gap between the fittings 10a and 10b and the lintel 40. Therefore, as soon as a horizontal force is applied to the seismic reinforced structure, the fittings 10a and 10b exert a function as compression braces.

[Embodiment 2]
In the second embodiment, fittings 10a and 10b manufactured by the square pipe will be described. In the following, the points different from the first embodiment will be described.

[Structure of fittings 10a and 10a]
In the fittings 10a and 10b of the second embodiment, the stile portion is manufactured by joining, for example, stainless steel square pipes by welding. The lattice portion is manufactured, for example, by forming a SUS304 Φ12 × t1.2 pipe into a square shape by press forming, providing a notch, and then fitting the pipe. The stile and the grid are joined by welding. In addition, by providing the outer frame with respect to the lattice portion, it is also possible to provide a portion to be attached. The shoji portion is provided by fitting a plate panel (for example, a polycarbonate resin plate having a polycarbonate resin as a core material and sandwiching the polycarbonate resin between glass plates) inside the stile portion. Here, the shoji portion may be fixed by adhering the shoji portion and the lattice portion. Further, a flint plate may be provided on the stile portion, and the sash portion may be fixed by sandwiching the sash portion between the flint plate and the lattice portion.
[Structure of stopper means 20a, b]
The stopper means 20a and b of the second embodiment include, for example, a stainless steel pipe member as the first guide member 21, a pipe member as the second guide member 22, and a stopper pin 23. The first guide member 21 is arranged in the inner space of the stile portion (square pipe) and is welded to the stile portion. The second guide member 22 penetrates the threshold material 30 and reaches into the base. The stopper pin 23 has a handle for movement in the axial direction, and is inserted into the first guide member 21 and the second guide member 22 from above. The handle of the stopper pin 23 protrudes from the side surface of the fittings 10a and 10b, and the stopper pin 23 is inserted and removed by moving the handle up and down. A window for moving the handle is provided on the side surface of the fittings 10a and 10a, that is, the side surface of the stile portion.

The insertion / removal of the stopper pin 23 is not limited to the method using the handle. For example, a part of the stile portion may have a half-split structure so that the stopper pin 23 can be directly inserted and removed. In that case, the cover plate is attached after the stopper pin 23 is inserted and removed.

[Effect of Embodiment 2]
As described above, since the lattice portions of the fittings 10a and b of the second embodiment are formed of hollow members, weight reduction can be expected as compared with the fittings 10a and b of the first embodiment. Further, since the first guide member 21 is provided inside the fittings 10a and 10b, the scenery is not impaired. In addition to the rigid metal (stainless steel, etc.), a fiber reinforced resin (for example, carbon fiber reinforced resin) can also be used for the lattice portion.

[Embodiment 3]
Hereinafter, various variations in the seismic reinforced structure of the present invention will be described as the third embodiment.

The fittings 10a and 10b may have a sliding door-like structure as well as a shoji-like structure. That is, one flat plate, plywood-shaped panel, or the like can be used as a proof stress material without providing a window portion on the fittings 10a and 10a. Materials for flat plates and plywood include stainless steel plates, steel plates, wood boards, fiber reinforced resins and the like. Further, for example, the seismic panels disclosed in Japanese Patent Application Laid-Open No. 2013-19211 can be applied as fittings 10a and b.

The fittings 10a and 10b having a shoji-like structure can be configured without including the plate panel. That is, the fittings 10a and 10b with the window portion open may be used.

The seismic reinforced structure of the present invention can be applied not only to cultural property buildings but also to various existing buildings, especially wooden structures. Further, the fittings 10a and 10b of the present invention can also be used as a shear wall. That is, the fittings 10a and 10b may be arranged so as to be sandwiched between the left and right pillar members.

The gap adjusting material 60 may be struck with screws against, for example, the pillar material 50a and / or the Kamoi material 40 if it is acceptable from the viewpoint of preserving the cultural property building.

The stopper means 20a and b may be any as long as they can prevent the fittings 10a and b from sliding. For example, the first guide member 21 may be directly fixed to the sill material 30 without using the stopper pin 23. Further, the stopper means 20a and b can be arranged not only in the lower corners of the fittings 10a and b but also in the upper corners of the fittings 10a and b.

[Earthquake resistance reinforcement performance]
The seismic reinforced performance of the seismic reinforced structure of the present invention was tested using a model of the seismic performance test apparatus as shown in FIG. That is, the test fitting 10c is set in the opening of the test frame structure having sufficient proof stress and the test is performed. As the fitting, the shoji-like latticed fitting shown in FIG. 10A is used, and the lower side of the fitting 10c is fixed by a stopper so as not to slide in the lateral direction, and a hydraulic jack is used to apply a horizontal force to the upper side of the fitting 10c. Apply and measure the shrinkage variation δ (mm) with respect to the load P (kN). Here, the seismic resistance reinforcing performance by the seismic resistance reinforcing structure is expressed as a load deformation curve showing a shrinkage variation δ (mm) with respect to a load P (kN). Below, the conditions and results of the test using the above model are described as examples.

[Example 1]
As shown in FIG. 10A, the seismic resistance reinforcing performance was tested using a fitting 10c having a shoji-like structure. This fitting 10c has a structure in which two lattice plates are sandwiched between two frame frame plates, and does not include a plate panel.

The stile frame plate has a length of 1940 mm, a width of 930 mm, a thickness of 6 mm, a vertical width of 38 mm for the upper and lower rails, a vertical width of 31 mm for the middle rail, a horizontal width of 38 mm for the vertical rail, and 1495 * 868 mm for the upper window portion (length * width). It is a stainless steel plate with a lower window (length * width) of 338 * 868 mm.

The grid plate has the same length, width, and thickness as the frame frame plate, and is a stainless steel plate having a vertical width of 46 mm for the upper and lower rails, a vertical width of 47 mm for the middle rail, and a horizontal width of 46 mm for the vertical rail. Laser processing of 11 vertical * 4 horizontal (44 total) windows between the upper and middle rails and 3 vertical * 4 horizontal (12 total) windows between the middle and lower rails It was provided by cutting out with. The window portion between the upper rail and the middle rail is 127.2 mm in length * 207 mm in width, and is separated by a horizontal wire and a vertical rail having a width of 8 mm, respectively. The window portion between the middle rail and the lower rail is 102 mm in length and 207 mm in width, and is separated by a horizontal wire and a vertical rail having a width of 8 mm, respectively.

The two stile frame plates and the two grid plates were joined with 51 SUS30 Φ hexagon bolts M6. A total of nine hexagonal bolts are placed on the upper rail at a position 19 mm from the upper side, 11.5 mm, 117 mm, 117.5 mm, 103.5 mm, 103.5 mm, 103.5 mm, 103.5 mm, and 117.5 mm from the left side. Coordinated with an interval of 117 mm and 11.5 mm. A total of nine hexagonal bolts were placed on the middle rail at the vertical center position of the middle rail at the same intervals as the upper rail. A total of nine hexagonal bolts were placed on the lower rail at a position 19 mm from the lower side with the same spacing as the upper rail. Each of the left and right vertical bars has 15 hexagonal bolts (30 in total, 6 of which overlap with those of the upper, middle, and lower bars), 19 mm from the left and right pieces, and 19 mm from the top. Coordination was performed with an interval of 158.2 mm * 11, 133 mm, 102 mm, and 133 mm. The arrangement of the hexagonal bolts on the left and right vertical rails corresponds to the center of the vertical width of the upper rail, the middle rail, and the lower rail, and the center of the vertical width of the horizontal crosspiece.

When a horizontal force was applied to the fitting 10c, the fitting 10c was deformed as shown in FIG. 10B. The load deformation curve at this time is shown in FIG. That is, it was confirmed that the illustrated fitting 10c has a proof stress of 8.47 kN with respect to the safety assurance level 1/30 specified in the "Important Cultural Property (Building) Seismic Basic Diagnosis Implementation Guidelines" of the Agency for Cultural Affairs. From the results of FIG. 11, it was found that the test fitting can realize the above safety assurance level with sufficient surplus power.

In the first embodiment, a slender-less plate was used as the lattice plate of the fitting 10c, but the desired seismic performance can be obtained by further adjusting the material, the size of the window portion, the pitch, etc. using the fitting 10c as the basic structure. .. Further, as the material, a fiber reinforced resin can also be used.

From the above experimental results, the advantageous seismic absorption effect of the seismic reinforced structure having a shoji structure including an integral structure made of a rigid material was clarified. This integrated structure can be used as a seismic structure of a more general main building. Furthermore, if a plate panel is added, an additional stack can be obtained in the seismic resistance range accordingly. This integrated lattice body can also be used, for example, by interposing it between two columns.
