2. Description of the Related Art In the Great Hanshin-Awaji Earthquake, private houses,
Buildings, expressways, and all other buildings were destroyed, and the damage was enormous in both human and physical aspects.However, due to the disaster, seismic measures for buildings were recognized again in Japan, an earthquake-prone country. This is also true, and in fact, after the disaster, research on new seismic countermeasures is being conducted more actively than before. At present, seismic isolation measures for buildings are generally implemented by placing a disc-like material called a seismic isolation method, which is made of a sandwich of rubber and iron plates, at the position of a reinforced concrete foundation. However, in the recent earthquake swarms in the Izu area, televisions show how many furniture falls and objects have fallen in apartments built using the conventional seismic isolation method. It proved to be less effective in preventing furniture from falling or falling objects. The cause of this is that vibrations caused by the vibration of an earthquake include longitudinal vibration and transverse vibration, and although the earthquake requires countermeasures for both vibrations, Is calculated using only the lateral vibration formula, and the existing seismic isolation method is designed based on this formula. In addition,
The existence of longitudinal vibration of the earthquake is evident from the case where railroad rails were deformed in a wavy manner in the Great Kanto Earthquake. Such longitudinal vibrations of earthquakes often cause products on display shelves to fall to the floor in stores such as convenience stores and supermarkets, and these damages are caused even by minor earthquakes that are not enough to collapse buildings. However, the conventional seismic isolation method has little effect on the longitudinal vibration of an earthquake as described above, and thus cannot prevent these damages.

[0003] A construction method generally called seismic isolation construction method implemented in a heavy building such as a high-rise building or a reinforced concrete structure can be represented as shown in FIG.
In the figure, the portion h1 is the first floor of the building, the portion h2 is the second floor of the building, and the triangles indicate the seismic isolation rubber of the laminated structure. Conventionally, seismic isolation methods used for high-rise buildings and heavy-weight buildings such as reinforced concrete structures use a rigid structure, as shown in FIG. 22 when an earthquake occurs. Seismic force N =
The structure which receives as h1 + h2 was adopted. However, although this seismic isolation method is conventionally used, high-rise buildings and reinforced concrete buildings are suitable for rigid buildings, but in detached houses such as wooden buildings and medium-to-low-rise steel frames, Because the feet have a pin structure, horizontal seismic force could not be received at the feet of the building, and the conventional seismic isolation method for high-rise buildings could not be applied.

At present, a cloth foundation is most widely used as a foundation for a detached house, and in fact, in the Building Standards Law, a wooden house foundation is intended for a plain concrete or reinforced concrete cloth foundation. However, since the cloth foundation is a thin and long foundation that receives the load of the upper building, the vibration of the earthquake exerts a great influence on the upper building, and the vibration may damage the foundation itself. Furthermore, when constructed on soft ground, there has been a problem that so-called uneven settlement occurs in which the earthquake causes a different amount of settlement of the foundation depending on the location. These phenomena were the major causes of collapse and damage of buildings. In other words, in a building that is built directly on the ground (a building that does not stake out), the fabric foundation is the foundation of a structure that is extremely vulnerable to earthquakes. Had a serious problem.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of such problems of the conventional seismic isolation method, and is intended for use in wooden houses and steel houses other than heavy-weight buildings such as high-rise buildings and reinforced concrete structures. For detached houses with a foot-pin structure, it can cope with both vertical and horizontal vibrations due to earthquakes, and it is effective not only for vibration of the building itself and uneven settlement due to vibration, but also for falling down of furniture etc. in the building The problem to be solved is to provide an anti-seismic rubber and a seismic proofing method using the rubber, which can prevent the collapse of display shelves such as convenience stores and fall of displayed products due to vibration. It is.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an anti-vibration rubber according to the present invention and an anti-vibration method using the rubber will be described with reference to the drawings. 1 to 5 are views showing a preferred embodiment of an anti-vibration rubber (7) according to the present invention, FIG. 2 is a side view of FIG. 1, and FIG. 5 is a side view of FIG. 3 and FIG. The anti-vibration rubber (7) according to the present invention is made of synthetic rubber or natural rubber, and has irregularities formed regularly and continuously over the entire surface on one side or both sides as shown in the figure. In the examples shown in FIGS. 1 and 2, the concave and convex surfaces are provided with convex portions intersecting diagonally, and concave portions are formed in a rhombic shape. In addition, the uneven surface is formed on both front and back surfaces. In the example shown in FIG. 3, the convex and concave surfaces are formed so that the convex surface is round, and in the example shown in FIG. 4, the convex surface is formed so as to be square. Is formed only on one side. In the present invention, the shape of the uneven surface of the anti-vibration rubber (7) is not limited at all,
For example, in the examples shown in FIGS. 3 and 4, a configuration may be adopted in which the number of convex surfaces is made smaller and many are formed, or a configuration in which concave and convex surfaces are provided on both front and back surfaces. Further, as other configurations, a configuration in which the unevenness is provided in a linear stripe shape (see FIG. 6), a configuration in which the unevenness is provided (see FIG. 7), a configuration in which the unevenness is provided in a concentric shape (see FIG. 8), or a concave surface and a convex surface in these examples. Is a preferable example. In this way, by forming the uneven surface on the surface or both the front and back surfaces of the anti-vibration rubber, the flexibility of the rubber is increased and the cushioning property is excellent, and the anti-vibration rubber and the ground (or a portion continuous with the ground) are formed. The ground contact area can be reduced, and the vibration of the earthquake is less likely to be transmitted to the upper part through the rubber cushion.

The area of the convex surface occupying the surface area is not particularly limited, and the area of the convex surface may be increased according to the axial force received from the upper portion. However, if the axial force received from the upper portion is not so large, the convex surface occupies the surface area. Is preferably smaller than the area of the concave surface. In this case, specifically, the area ratio of the convex surface to the concave surface is preferably about 70% to 80%. The reason for this is that, by making the area of the convex surface smaller than the area of the concave surface, the ground contact area between the anti-seismic rubber and the ground becomes smaller, and it becomes difficult for the vibration of the earthquake to be transmitted to the upper portion through the anti-vibration rubber. If the area ratio of the convex surface is too small, the contact area with the ground is too small, and the stability is deteriorated. Also, the depth of the uneven surface is not limited, but the depth of the concave surface (height of the convex surface) is equal to or less than half of the total rubber thickness, preferably 15 to
It is preferred to be about 50%. This is because if the depth of the concave surface is more than half of the total rubber thickness, the stability will be poor and the convex part will be easily damaged.If the concave surface is too shallow, the deformation of the rubber will cause unevenness. This is because it becomes less clear and the vibration of the ground is easily transmitted to the upper part.
Further, the thickness of the anti-vibration rubber (7) itself is not limited at all, and may be appropriately set according to an object to be used.
For example, a configuration in which a plurality of rubber plates are stacked may be employed.
In addition, when showing a preferable numerical value for reference, regarding the size,
100mm x 100mm, 100mm x 200mm, 1
Examples of the thickness include values of about 20 mm and 30 mm, such as 00 mm × 300 mm and 100 mm × 500 mm. In addition, it is preferable to set the size according to the size of the object and the thickness according to the applied compressive force, and these dimensions are set to 4 kg / cm ² (long-term). It is an example when it is set. Also,
The material may be either natural rubber or synthetic rubber and is not particularly limited. However, the pressure-receiving surface allowable stress is 4 kg / cm ² (long term), the Hs hardness is 60 °, and the allowable deflection is 6 mm (length 100 mm).
It is preferable to use a synthetic rubber having a characteristic of about mm × width 100 mm × thickness 20 mm).

Hereinafter, the allowable stress of the pressure-receiving surface of the earthquake-proof rubber is 4 kg /
An example of a method for calculating a required rubber pressure receiving area when the area is set to cm ² will be described. Calculate the axial force applied to the base of the first floor in a two-story building. Fixed load: Roofing 65kg / m ²

mx 1.8m = 534.6kg, hut set 10kg x 3.
6m = 36.0kg, ceiling 40kg / m ² × 1.8mx
1.8m x 2 places = 259.2kg, 2nd floor wooden floor (50

2 kg, wooden wall (with sash window) 65 kg / m ² × 1.

It becomes 0 kg. Therefore, the required rubber receiving area is 2110
^{kg ÷ 4kg / cm 2 = 527.5cm} 2 next, when the rubber width 10cm length of about 53cm (530 cm ²⁾ is required. When a horizontal force (wind pressure, seismic force) short-term load is applied to the first-floor column base pin structure, if long-term column axial force = P and horizontal force = N, short-term load = P + N, when a wind or earthquake occurs Shall be received at the degree of rubber sink (cushion).

FIGS. 9 to 13 are schematic perspective views showing a preferred embodiment of an earthquake-proof construction method using the above-mentioned earthquake-proof rubber.
This seismic isolation method is a seismic isolation method that is suitably used for wooden buildings. First, as shown in FIG. 9, laying stones (1) and crushed stones (2) over the entire area of the first-floor building area of a detached house, A base bar (3) is vertically and horizontally braided thereon, and the base bar (3) is connected to a rising bar (not shown), and a concrete (4) is poured into this structure to give a solid foundation. (Funa-shaped total foundation).

Next, the slab stone (5) is fixed integrally with the foundation to a required position on the slab of the solid foundation (see FIG. 10), and the top surface of the slab stone (5) and the rising portion (6) of the solid foundation are formed. Lay the anti-vibration rubber (7) at the required position (see FIG. 11). It is preferable that the slab stone (5) is integrally formed with the foundation by inserting a reinforcing bar and joining the reinforcing stone to the base reinforcement (3).

A bundle (8) and a base (9) are placed on a slab (5) on which an anti-vibration rubber (7) is laid and a rising portion (6) of a solid foundation. The base (6) and the base (9) are fixed to the slab (5) by the anchor bolt (10) so that the seismic rubber (7) is interposed between the bundles and between the rising portion of the solid foundation and the base. ) And the bundle material (8) are connected to each other by the strip hardware (11) (see FIG. 12).
FIG. 13 is a view showing a connecting portion between the foundation (6) and the base (9), in which (12) is a level mortar, (13) is a rubber washer, and (14) is a steel washer. The washer (14) may be a flat washer, but it is preferable to use a spring washer since the set of the anti-vibration rubber (7) can be compensated to some extent by the spring property of the washer.

After connecting the foundation (6) and the base (9) and the slab (5) and the bundle (8) respectively, a pillar (15) is erected at a required position on the base (9), and 16) Bundle material (8)
The upper part is joined to the base (9) (see FIG. 14), and a building is constructed thereon, and finally a building having an earthquake-proof structure as shown in FIG. 15 is constructed. Although FIG. 15 shows an example in which the building is a wooden one-story house, the seismic isolation method according to the present invention is sufficiently applicable to a two-story or three-story house.

The anti-vibration rubber (7) laid between the rising portion (6) of the solid foundation and the base (9) is provided at least in a portion where the column (15) is erected on the upper surface of the base (9). It is laid over the entire area. In the present invention, the anti-vibration rubber (7) is most preferably arranged at the lower part of the standing portion of the column (15) and at the midpoint between the column (15) and the column (15) as shown in the figure. At least the pillar (1
5) The arrangement is not particularly limited as long as it is laid on the erected portion. For example, it may be configured to be laid only on the lower part of the erected portion of the pillar (15), or it may be laid on the solid foundation ( 6) It may be configured to be laid over the entire surface between the top surface and the base (9) lower surface.

The gap between the rising portion (6) of the solid foundation and the lower surface of the base (9) other than the portion where the pillar (5) is erected on the upper surface of the base (9) is coking. It is preferable to fill the material. By filling the gap between the rising portion (6) of the solid foundation and the base (9) with the caulking material, it is possible to prevent the intrusion of rainwater and the like, and to obtain an earthquake-proof building structure having an excellent waterproof effect.

The seismic isolation method according to the present invention can be used not only for wooden buildings but also for steel buildings. In a steel frame building, after forming a solid foundation in the same procedure as described above, as shown in FIG. 16, an anti-vibration rubber (7) is placed between the top surface of the rising portion (6) of the solid foundation and the lower surface of the base plate (16). Lay the foundation (6) and the base plate (16) together with the anchor bolts (1) via the anti-vibration rubber (7).
0). FIG. 17 is a view showing a connection portion between a base (6) and a base plate (16) provided at the bottom of a pillar (15) in a steel frame building.

The anti-vibration rubber (7) can be sufficiently sandwiched and fixed by the connecting member and its own weight even if it is simply laid. However, in some cases, it may be configured such that it is fixed by an adhesive or the like before being sandwiched. .

As described above, the operation of the solid foundation and the seismic isolation are achieved by adopting the seismic construction method of laying the seismic rubber between the top surface of the rising portion of the solid foundation and the lower surface of the base as a solid foundation. An excellent seismic-proof structure building can be obtained by the additive action of the rubber action. First, since the foundation is a solid foundation, it is possible to receive the vibration of the earthquake on a large flat area foundation formed over the entire building construction area, and the earthquake resistance is strong. And because the weight of the foundation itself is large, the position of the center of gravity of the building can be lowered, stability against earthquakes can be increased, and construction can also be performed on soft ground, preventing uneven settlement due to earthquake vibration. can do. Secondly,
Seismic rubber is laid between the foundation and the base, so it functions as a cushion against pitching of earthquakes that cannot be covered by solid foundation, preventing furniture and other objects in the building from falling over can do.

The seismic isolation method according to the present invention is described below.
The structure of the portion above the base is not limited at all, and any conventionally known building structure can be suitably used.

FIGS. 18 (a) and 18 (b) are explanatory views showing the operation of the seismic isolation method according to the present invention.
(B) shows a case of an upward vibration at the time of an earthquake, and (c) shows a time of a downward vibration at the time of an earthquake. As shown, when the seismic isolation method according to the present invention is used, the foundation (6) shakes as the ground (G) shakes, but the expansion and contraction of the anti-vibration rubber (7) between the building (K) and the foundation (6). As a result, the vertical vibration of the building (K) itself is greatly reduced.

FIG. 19 is a schematic explanatory view for explaining the operation when the seismic isolation method according to the present invention is applied to a wooden structure having a foot pin structure. In the drawing, h1 indicates the first floor of the building, h2 indicates the second floor of the building, triangles indicate anti-vibration rubber, and arrows indicate the direction of the load. When the seismic isolation method according to the present invention is applied to a wooden structure with a foot pin structure, the horizontal seismic force N due to the occurrence of an earthquake acts on the beam at the boundary between the first and second floors of the building as N = h2 + h1 / 2, When the struts receive the horizontal force due to the compressive force, only the vertical direction, that is, the axial force of compression and tension acts at the foot of the building. By receiving the axial force of compression and tension with the anti-vibration rubber, the entire building Vibration can be reduced. Although not shown, when the seismic isolation method according to the present invention is applied to a steel structure having a foot pin structure,
When the struts receive horizontal force due to tensile force, only the vertical direction, that is, the axial force of compression and tension acts at the foot of the building. By receiving the axial force of compression and tension with seismic rubber, the entire building Vibration can be reduced.

FIG. 20 is a perspective view showing another embodiment of the anti-vibration method according to the present invention, in which an anti-vibration rubber (7) is laid on a floor surface (Y) and a bottom surface is provided on the anti-vibration rubber (7). The display shelf (17) is placed so as to touch the display shelf. The display shelf (1
7) may be configured to simply be placed on the anti-vibration rubber (7). However, in order to prevent the display shelf (17) from slipping off from the anti-vibration rubber (7), the display shelf and the anti-vibration rubber are connected with a metal fitting or an adhesive. It may be fixed with an agent or the like. Further, in order to prevent the anti-vibration rubber (7) from sliding on the floor surface (Y), the anti-vibration rubber (7) and the floor surface (Y) may be similarly fixed with a connection fitting, an adhesive or the like. It is preferable to lay the anti-vibration rubber (7) at least at the four corners of the display shelf (17) as shown in the figure, but the laying position is not limited at all unless the bottom surface of the display shelf is in contact with the floor surface. In some cases, it may be laid over the entire bottom surface of the display shelf. In addition, display shelf (1
When 7) is provided in contact with a wall, an anti-vibration rubber (7) must be interposed between the wall and the display shelf so that vibrations from the wall can be absorbed by the anti-vibration rubber (7). Is preferred.

FIG. 21 is an explanatory view showing the operation when an anti-vibration rubber is laid between the bottom of the display shelf and the floor, and FIG.
(B) shows an anti-seismic space between the floor and the bottom of a shelf with a high and low depth when a rubber cushion is laid between the floor and the bottom of the shelf on a shelf with a low depth. (C) shows a case where rubber is laid, and (C) shows a case where earthquake-proof rubber is interposed between the floor surface and the shelf bottom surface and between the shelf back surface and the wall surface, respectively. Assuming that the height of the center of gravity of the shelf from the floor is h, the weight of the shelf is P, and the depth of the shelf is L, the overturning moment of the shelf M = P × h and the reaction force N = M / L at the foot . P =
1000 kg, h1 = 50 cm, h2 = 100 cm, L
If 1 = 100 cm and L2 = 50 cm, in the case of (A), M = 1000 kg × 50 cm = 50,000 kg · c
m, N1 (compression) = N2 (tensile) = 50,000 kg
cm ÷ 100 cm = 500 kg <P. on the other hand,
In the case of (B), M = 1000 kg × 100 cm = 100
000 kg · cm, N1 (compression) = N2 (tensile) = 1
00000 kg · cm ÷ 50 cm = 2000 kg> P. That is, even if the shelves have the same weight, the falling moment and the reaction force differ depending on the height and the depth.
Therefore, in a shelf having a high height and no depth as shown in (B), it is necessary to fix the floor surface, the anti-seismic rubber, and the display shelf with anchor bolts or the like in order to prevent falling. Also, (C)
When installing a shelf that is high and has no depth along the wall, fixing the wall, the shelf, and the anti-seismic rubber with anchor bolts in addition to fixing the feet can prevent the shelf from falling over. .

The size, shape, and type of the display shelf (17) are not limited at all, and may be used for display shelves in convenience stores and supermarkets, as well as in showcases in jewelry stores and clothing stores, and in bookcases in bookstores. And a large number of products placed on shelves can be the target. In this way, by interposing the anti-vibration rubber between the display shelf and the floor surface, the rattling of the vertical vibration caused by the earthquake can be absorbed by the anti-vibration rubber, and the products placed on the shelf fall. Can be prevented.

[0031]

As described above, according to the first aspect of the invention, the degree of flexure of the rubber is increased by the regular and continuous irregularities formed on the entire surface of one side or both sides of the anti-vibration rubber. In addition to being excellent in cushioning property, the ground contact area is reduced, and vibration is hardly transmitted to the upper part of the anti-vibration rubber, so that an excellent anti-vibration rubber capable of effectively suppressing vibration of buildings and the like is obtained.

According to the second to seventh aspects of the present invention, the following effects can be obtained. First, since the foundation is a solid foundation, the vibration of the earthquake can be received by a large flat area foundation formed over the entire building construction area, and the earthquake resistance is strong. And because the weight of the foundation itself is large, the position of the center of gravity of the building can be lowered, stability against earthquakes can be increased, and construction can also be performed on soft ground, preventing uneven settlement due to earthquake vibration. can do. Furthermore, since the rubber is laid between the foundation and the base, the rubber acts as a cushion against the pitching of the earthquake that cannot be handled by the solid foundation, and the furniture etc. in the building falls down. Can be prevented. Furthermore, compared to the conventional seismic construction method, it is possible to obtain much higher safety at a low cost with a much simpler construction, and because the ventilation between the foundation and the base is improved, moisture is removed and corrosion of the base is prevented. Can be prevented. Further, it is possible to prevent vibration from an unpleasant floor due to a car or construction.

According to the invention of claim 8, the seismic isolation rubber laid between the floor and the shelf plays the role of a cushion for absorbing the rattling of the floor due to the longitudinal vibration of the earthquake. This can prevent the products displayed on the display shelves of convenience stores and supermarkets from falling on the floor.
