【００２２】
上記吸振ゴム材９Ｂの側面に、直径が５ｍｍ程度の十字状貫通穴９ｅ，９ｅをあけると、よりたわみやすくなって、吸振・吸音性が向上する。
【００２３】
上記の各寸法形状で成形した吸振ゴム材９（Ａ，Ｂ）の圧縮試験を行ったところ、図５に示すように、たわみ用凹凸部９ｃのたわみ量は、１００Ｋｇ／平方ｍの荷重で約１．２ｍｍ、２００Ｋｇ／平方ｍの荷重で約１．７ｍｍ、３００Ｋｇ／平方ｍの荷重で約２．４ｍｍ、４００Ｋｇ／平方ｍの荷重で約３．２ｍｍであり、住宅等の場合、通常は２００Ｋｇ／平方ｍの耐荷重で充分であることから、圧縮性能を満足していることがわかる。

上記コンクリート基礎台１の上にアンカーボルト２で木製土台３を固定する必要の無い箇所では、図２（Ｃ）に示すように、コンクリート基礎台１に上に乗せた吸振ゴム材９（Ａ，Ｂ）を、フラットな凹部９ｄを利用してコンクリート釘７を打ち込んで簡単に直接固定することもできる。このフラットな凹部９ｄにより、コンクリート釘７の頭部が吸振ゴム材９（Ａ，Ｂ）の上面から突出しなくなる。
【００２６】
上記のように構成すれば、コンクリート基礎台１の上に吸振ゴム材９（Ａ，Ｂ）を介して木製土台３を固定することにより、図１（Ｂ）及び図２（Ａ）（Ｂ）に示すように、木製土台３の下面が吸振ゴム材９（Ａ，Ｂ）の厚みＴ１（例えば２５ｍｍ）だけコンクリート基礎台１の上方に浮いて、コンクリート基礎台１の上（天端）に直に接しなくなるため、木製土台３がコンクリート基礎台１の湿気を吸うおそれがなくなって腐朽しなくなり、耐久性が向上する。また、コンクリート基礎台１の天端モルタルのがたつきを吸振ゴム材９（Ａ，Ｂ）で吸収できるので、木製土台３が傷められることがない。
【００２７】

【００２８】
さらにまた、コンクリート基礎台１と木製土台３との間に吸振ゴム材９（Ａ，Ｂ）が介在しているため、大型トラックの走行振動や地震の振動等がコンクリート基礎台１の上の吸振ゴム材９（Ａ，Ｂ）で吸振されて木製土台３に伝わりにくくなるので、住宅の吸振性や耐震性も向上する。
【００２９】

【００３０】
上記換気プレート１１に水切り板１１ｂを一体成形することにより、換気プレート１１の取り付け作業だけで、従来では別々に取り付けていた水切り板１１ｂも同時に取り付けることができる。また、換気プレート１１と水切り板１１ｂを別々に製造するよりもコスト安になると共に、取り扱いも容易になる。
【００３１】
上記換気プレート１１と水切り板１１ｂの板厚は、合成樹脂製であるときは約１〜２ｍｍ、アルミ製であるときは約１ｍｍ、鉄製であるときは約０．２〜０．３ｍｍが適当である。なお、換気プレート１１の釘１２や木ねじで取り付けた部分は、サイディング（化粧板）１３の下部で隠されると共に、換気プレート１１の下端曲げ部１１ｃはコンクリート基礎台１の外面の基礎モルタル１４の厚みゲージとなる。

【００３３】
また、図７（Ｂ）の第２参考例に示すように、幅方向に所定の間隔Ｌ２（例えば６ｃｍ）でほぞ穴３ｂをあけ、小型正方形状（丸状でも可）に成形した吸振ゴム材９Ｄのほぞ９ｈを嵌め込んで取り付けても良い。さらに、図８（Ａ）の第３参考例に示すように、木製土台３のほぞ穴３ｂに大型正方形状に成形した吸振ゴム材９Ｅのほぞ９ｈを嵌め込んで取り付けても良い。さらにまた、図８（Ｂ）の第４参考例に示すように、木製土台３のほぞ穴３ｂに大型正方形状の吸振ゴム材９Ｆを釘７や木ねじで取り付けても良い。
【００３４】

以上の説明からも明らかなように、本発明の木造住宅及び木質系住宅用土台の固定構造は、吸振ゴム材により、大型トラックの走行振動や地震の振動等がコンクリート基礎台の上の吸振ゴム材で吸振されて木製土台に伝わりにくくなるので、住宅の吸振性や耐震性が向上する。
【００３７】
また、隣り合う吸振ゴム材の間が換気口となるから、従来のようにコンクリート基礎台自体に基礎換気口をあける必要がなくなり、地震等によるクラックの発生や破損がなくなって、コンクリート基礎台の強度が向上すると共に、換気口はコンクリート基礎台の全周囲に設けられるため、床下換気が良好になる。
【００３８】
さらに、木製土台がコンクリート基礎台に直に接しないから、コンクリート基礎台の湿気を吸うおそれがなくなって腐朽しなくなり、耐久性が向上すると共に、コンクリート基礎台の天端モルタルのがたつきが吸振ゴム材で吸収されるので、木製土台が傷められることもなくなる。
【００３９】
また、吸振ゴム材のたわみ性がより向上すると共に、吸振ゴム材が横滑りするのを未然に防止できる。また、各凹凸部に雨水や水滴等が溜まらないので、コンクリート基礎台が湿気たり、木製土台が腐るのを防止できる。さらに、釘の打ち込みが簡単になり、釘の頭部が吸振ゴム材の上面よりも突出しなくなる。さらにまた、吸振ゴム材を正確に位置決めできると共に、吸振ゴム材がよりたわみやすくなって、吸振・吸音性が向上する。
【００４０】

BACKGROUND OF THE INVENTION
The present invention relates to a wooden housing and a wooden base mounting fixing structure capable of improving vibration absorption and earthquake resistance, underfloor ventilation, and the like in wooden houses and wooden houses.
[0002]
[Prior art]
Conventionally, as a construction method for building a wooden house and a wood-based house (including a house with a store, etc.), as shown in FIG. 9, a wooden base 3 is fixed to a concrete base 1 with anchor bolts 2 and this wooden base. A pillar 4 is erected on 3 or a floor structure material is spread and fixed. Moreover, in order to ventilate under the floor, a large number of basic ventilation openings 1a,.
[0003]
[Problems to be solved by the invention]
However, since the vibration of a large truck, the vibration of an earthquake, etc. are directly transmitted from the concrete foundation 1 to the wooden base 3, the vibration absorption and earthquake resistance of the house are poor. In addition, in the case of an earthquake or the like, crack a occurs in the ventilation opening 1a of the concrete foundation 1 or breaks from this portion, the strength of the concrete foundation 1 is reduced, and the position and number of the ventilation openings 1a Is limited, so underfloor ventilation is bad. Furthermore, since the lower surface of the wooden base 3 is in direct contact with the top (top) of the concrete base 1, the wooden base 3 easily absorbs moisture from the concrete base 1 and deteriorates, resulting in a decrease in durability. At the same time, the wooden base 3 is damaged due to the rattling of the top mortar of the concrete base 1.
[0004]
The present invention has been made to solve the above-described problems, and is a wooden house and a wooden housing base that can improve vibration absorption and earthquake resistance and improve underfloor ventilation in wooden houses and wooden houses. It is an object of the present invention to provide a fixing structure.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention fixes a wooden base via a hard vibration-absorbing rubber material arranged at a predetermined interval on a concrete foundation of a wooden house and a wooden housing, and adjoins the vibration-absorbing rubber. On the other hand, the vibration-absorbing rubber material has a circular or polygonal side surface, a concentric deflection uneven portion formed on the upper surface, and a concentric anti-slip uneven surface on the lower surface. Are formed, a radial draining groove is formed in each uneven portion, a flat recess for driving a nail is formed in a part of the uneven portion for deflection, a center hole penetrating the upper surface and the lower surface is formed, and the side surface The present invention provides a fixing structure for a wooden house and a wooden housing base, characterized in that a through hole is formed in the base.
[0006]
According to the present invention, since the vibration absorbing rubber material is interposed between the concrete foundation and the wooden base, traveling vibrations of large trucks, earthquake vibrations, etc. are absorbed by the vibration absorbing rubber material on the concrete foundation. Since it is difficult to transmit to the wooden base, the vibration absorption and earthquake resistance of the house are improved. In addition, since there is a ventilation opening between adjacent vibration-absorbing rubber materials, there is no need to open a foundation ventilation opening in the concrete foundation itself, cracks and damage due to earthquakes, etc. are eliminated, and the strength of the concrete foundation is improved. At the same time, the ventilation openings are provided all around the concrete foundation so that ventilation under the floor is good.
[0007]
Furthermore, by fixing the wooden base on the concrete base via a vibration-absorbing rubber material, the bottom surface of the wooden base does not directly touch the top (top) of the concrete base, so it absorbs moisture from the concrete base. There is no danger of rot and the durability is improved, and the vibration of the top mortar of the concrete foundation is absorbed by the vibration-absorbing rubber material, so that the wooden base is not damaged.
[0008]
The vibration-absorbing rubber material has a circular shape or a polygonal shape in plan view, a concentric deflection uneven portion is formed on the upper surface, a concentric anti-slip uneven portion is formed on the lower surface, and each uneven portion has a radial shape. With a structure in which a water draining groove is formed, a flat recess for driving a nail is formed in a part of the concave / convex portion for deflection, a central hole that penetrates the upper surface and the lower surface is formed, and a through hole is formed in the side surface Therefore, the flexibility of the vibration-absorbing rubber material is further improved by the concave / convex portion for deflection, and the side of the vibration-absorbing rubber material can be prevented from slipping by the concave / convex portion for anti-slip. In addition, the draining groove portion prevents rainwater or water droplets from accumulating on each of the uneven portions, so that it is possible to prevent the concrete foundation from getting wet and the wooden foundation from rotting. Further, the flat recess makes it easier to drive the nail and the head of the nail does not protrude from the top surface of the vibration-absorbing rubber material. Furthermore, the vibration-absorbing rubber material can be accurately positioned using the center hole, and the vibration-absorbing rubber material is more easily bent by the through hole, so that the vibration absorption and sound absorption properties are improved.
[0009]
According to a second aspect of the present invention, the vibration-absorbing rubber material can be positioned through the center hole with respect to the bolt fixed to the concrete foundation, and the wooden foundation can be fixed to the concrete foundation with the bolt. With this structure, it is possible to reliably position the vibration-absorbing rubber material by simply passing the center hole of the vibration-absorbing rubber material with respect to the bolt (including the sleeve) fixed to the concrete foundation, and the wooden base is made concrete with this bolt. Can be fixed to the base.
[0010]
According to a third aspect of the present invention, the vibration-absorbing rubber material can be fixed to a concrete foundation by driving a concrete nail from the upper surface. With this structure, the vibration-absorbing rubber material can be easily fixed on the concrete base with nails.
[0011]
According to a fourth aspect of the present invention, the vibration-absorbing rubber material can be configured to be attached in advance to the lower surface of the wooden base. With this structure, the work of fixing the vibration-absorbing rubber material on the concrete foundation with bolts or nails is not required, and there is no need to forget to place the vibration-absorbing rubber material.
[0012]
As in claim 5, a ventilation plate having a ventilating hole for fenders is attached to the outer surface of the wooden base so as to close a ventilation opening between the concrete foundation and a draining plate is attached to the ventilation plate. It is preferable to integrally mold. With this structure, the draining plate is integrally formed with the ventilation plate, so it is possible to attach the draining plate that was previously separately attached by simply attaching the ventilation plate to the outer surface of the wooden base with nails or wood screws. Workability is improved.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, a wooden base 3 is fixed with anchor bolts 2 through hard vibration-absorbing rubber materials 9 (A, B) arranged on a concrete base 1 at a predetermined interval T, and this wooden base 3 The column 4 is set up on the floor, and the floor structure material is spread and fixed. In addition, the concrete base stand 1 does not have a basic ventilation opening for under-floor ventilation, which was conventionally necessary.
[0014]
As shown in FIG. 3, as the hard vibration-absorbing rubber material 9A of the first embodiment, for example, Neoplus S-95 [synthetic rubber fiber] manufactured by Kuriyama Co., Ltd. can be used, and its compressive strength is 800 kg / square. cm or more. The physical properties are shown in Table 1.
[0015]
[Table 1]

[0016]
The vibration-absorbing rubber material 9A has a circular shape in plan view , has a center hole 9a, has an outer diameter D of about 101 mm, and a thickness T1 of about 25 mm. The anti-slip uneven portions 9b,..., 9b are formed in a concentric shape with a fine pitch (about 1 to 5 mm) and height (about 1 mm) such as a square shape, a triangular shape, and a semicircular shape. In addition, the fine uneven part which is not concentric may be sufficient.
[0017]
Further, on the surface on which the wooden base 3 is placed, concavity and convexity portions 9c,..., 9c for bending are formed concentrically with a large pitch. It may be a large uneven part which is not concentric. The deflection uneven part 9c has, for example, a convex part width W1 of 8 mm, a concave part width W2 of 2 mm, and an uneven part height T2 of about 4 mm. Flat concave portions 9d and 9d for directly fixing with concrete nails 17 (see FIG. 2C) to be described later are formed at two locations on the diagonal line of the concave and convex portions 9c for bending.
[0018]
If cross-shaped through-holes 9e and 9e having a diameter of about 5 mm are formed on the side surface of the vibration-absorbing rubber material 9A, the vibration-absorbing rubber material 9A becomes easier to bend and improves the vibration absorption and sound absorption.
[0019]
FIG. 4 shows a hard vibration-absorbing rubber material 9B of the second embodiment having a regular square shape in plan view and having a center hole 9a, for example, having a width W of 105 mm and a thickness T1 of about 25 mm. There is a non-slip uneven portion 9b having a concentric fine pitch (about 1 to 5 mm) and height (about 1 mm), such as a square shape, a triangular shape, and a semicircular shape, on the surface to be placed on the concrete base 1. ,..., 9b are formed. In addition, the fine uneven part which is not concentric may be sufficient. For this concentric anti-slip uneven portion 9b, radial drain grooves 9f are formed with a fine width (about 2 mm) and depth (about 1 mm), for example, at intervals of 60 degrees.
[0020]
Further, on the surface on which the wooden base 3 is placed, concavity and convexity portions 9c,..., 9c for bending are formed concentrically with a large pitch. It may be a large uneven part which is not concentric. The bending uneven part 9c has, for example, a convex part width W1 of 8 mm, a concave part width W2 of 2 mm, and an uneven part height T2 of about 5 mm. Flat concave portions 9d and 9d for directly fixing with concrete nails 17 (see FIG. 2C) to be described later are formed at two locations on the diagonal line of the concave and convex portions 9c for bending. In the concave / convex portions 9c for bending except for the flat concave portions 9d, 9d on the diagonal line, draining concave portions 9g,..., 9g having the same shape as the concave portion 9d are formed. The flat recess 9d may be used as the draining recess 9g, and the draining recess 9g may be used as the flat recess 9d. The vibration-absorbing rubber material 9B has a regular quadrangular shape, and is formed with concentric anti-slip uneven portions 9b and flexural uneven portions 9c, which can cope with vibrations in almost all directions. Become.
[0021]
Due to the draining groove 9f and the draining recess 9g (the recess 9d for the nail 17 is also a part of the draining recess) of the vibration absorbing rubber material 9B, rain water, water droplets, etc. Since it does not collect in a recessed part, it can prevent that the concrete base stand 1 becomes damp, and the wooden base 3 rots.
[0022]
If cross-shaped through-holes 9e and 9e having a diameter of about 5 mm are formed on the side surface of the vibration-absorbing rubber material 9B, the vibration-absorbing rubber material 9B becomes easier to bend and improves vibration absorption and sound absorption.
[0023]
When a compression test was performed on the vibration-absorbing rubber material 9 (A, B) molded with each of the above dimensions and shapes, as shown in FIG. 5, the deflection amount of the concave / convex portion for deflection 9c was about 100 kg / square m. 1.2 mm, about 1.7 mm at a load of 200 Kg / square m, about 2.4 mm at a load of 300 Kg / square m, and about 3.2 mm at a load of 400 Kg / square m. It can be seen that the load capacity of / m 2 is sufficient, so that the compression performance is satisfied.
[0024]
When the wooden base 3 is fixed via the vibration-absorbing rubber material 9 (A, B) on the concrete base 1, the lower end of the anchor bolt 2 is attached to the concrete base 1 as shown in FIG. The sleeve 6 that can be fitted into the center hole 9a of the vibration-absorbing rubber material 9 (A, B) is inserted into the anchor bolt 2 and the vibration-absorbing rubber material 9 (A, B) is embedded. ). When the center hole 9a has the same diameter as the anchor bolt 2, the sleeve 6 is not necessary. Then, the wooden base 3 is fixed on the concrete base 1 by fitting a nut 5 in the counterbore 3 a of the wooden base 3 and screwing the nut 5 into the anchor bolt 2.
[0025]
In a place where it is not necessary to fix the wooden base 3 with the anchor bolt 2 on the concrete base 1, the vibration absorbing rubber material 9 (A, B) can also be directly fixed directly by driving the concrete nail 7 using the flat recess 9d. The flat concave portion 9d prevents the head of the concrete nail 7 from protruding from the upper surface of the vibration absorbing rubber material 9 (A, B).
[0026]
If comprised as mentioned above, by fixing the wooden base 3 on the concrete base stand 1 via the vibration-absorbing rubber material 9 (A, B), FIG. 1 (B) and FIG. 2 (A) (B) As shown in the figure, the lower surface of the wooden base 3 floats above the concrete base 1 by a thickness T1 (for example, 25 mm) of the vibration-absorbing rubber material 9 (A, B), and directly above the concrete base 1 (top edge). Therefore, the wooden base 3 is not likely to absorb the moisture of the concrete base 1 and does not decay, thereby improving durability. Moreover, since the vibration of the top mortar of the concrete base 1 can be absorbed by the vibration absorbing rubber material 9 (A, B), the wooden base 3 is not damaged.
[0027]
Further, as shown in FIG. 2 (B), the space between adjacent vibration-absorbing rubber materials 9 (A, B) at a predetermined interval T becomes a ventilation port 8, so that it is necessary to open a basic ventilation port in the concrete foundation 1 itself. This eliminates the occurrence of cracks and damage due to earthquakes and the like, and the strength of the concrete foundation 1 is improved. Moreover, since the ventilation opening 8 is provided in the perimeter of the concrete foundation stand 1, ventilation under the floor is favorable.
[0028]
Furthermore, since the vibration-absorbing rubber material 9 (A, B) is interposed between the concrete foundation 1 and the wooden base 3, vibrations of large trucks, vibrations of earthquakes, etc. are absorbed on the concrete foundation 1. Since it is absorbed by the rubber material 9 (A, B) and is difficult to be transmitted to the wooden base 3, the vibration absorbing property and earthquake resistance of the house are also improved.
[0029]
As shown in FIG. 6, an inverted L-shaped draining plate 11 b is integrally formed on the outer surface of a belt-like ventilation plate 11 in which fendering ventilation holes 11 a,..., 11 a (for example, holes of 10 mm or less) are formed vertically and horizontally. Then, this ventilation plate 11 is applied to the outer surface of the wooden base 3 and is attached to the wooden base 3 with a nail 12 or a wood screw in a state where the ventilation opening 8 between the concrete base 1 and the wooden base 3 is closed.
[0030]
By integrally forming the draining plate 11b on the ventilation plate 11, the draining plate 11b that has been separately attached in the past can be attached at the same time only by attaching the ventilation plate 11. In addition, the cost is lower than the manufacturing of the ventilation plate 11 and the draining plate 11b separately, and the handling is facilitated.
[0031]
Appropriate thicknesses of the ventilation plate 11 and draining plate 11b are about 1-2 mm when made of synthetic resin, about 1 mm when made of aluminum, and about 0.2-0.3 mm when made of iron. is there. The portion of the ventilation plate 11 attached with the nail 12 or the wood screw is hidden under the siding (decorating plate) 13, and the lower end bent portion 11 c of the ventilation plate 11 is the thickness of the foundation mortar 14 on the outer surface of the concrete foundation 1. It becomes a gauge.

In the above embodiment, a wooden house is taken as an example, but it goes without saying that the present invention can also be applied to a wooden house.
[0036]
【The invention's effect】
As is clear from the above description, the structure for fixing the wooden house and the wooden base of the present invention is made of a vibration absorbing rubber material, so that the vibration of large trucks and the vibration of earthquakes are absorbed on the concrete foundation. Because it is absorbed by the material and difficult to be transmitted to the wooden base, the vibration absorption and earthquake resistance of the house are improved.
[0037]
In addition, since there is a ventilation opening between adjacent vibration-absorbing rubber materials, there is no need to open a foundation ventilation opening in the concrete foundation itself as in the past. The strength is improved and the ventilation openings are provided all around the concrete foundation so that the underfloor ventilation is good.
[0038]
In addition, since the wooden base does not contact the concrete foundation directly, there is no risk of sucking moisture from the concrete foundation, it will not decay, the durability will be improved, and the shaking of the top mortar of the concrete foundation will be absorbed. Since it is absorbed by the rubber material, the wooden base is not damaged.
[0039]
In addition, the flexibility of the vibration absorbing rubber material can be further improved, and the vibration absorbing rubber material can be prevented from slipping. Moreover, since rainwater, water droplets, etc. do not collect in each uneven | corrugated | grooved part, it can prevent that a concrete foundation base damps or a wooden base rots. Further, the nail can be driven easily, and the head of the nail does not protrude from the upper surface of the vibration-absorbing rubber material. Furthermore, the vibration-absorbing rubber material can be accurately positioned, and the vibration-absorbing rubber material can be more easily bent to improve vibration absorption and sound absorption.
[0040]
If it is set as the structure of Claim 2, while being able to position a vibration-absorbing rubber material reliably, a wooden base can be fixed to a concrete foundation with a volt | bolt. If it is set as the structure of Claim 3, a vibration-absorbing rubber material can be easily fixed on a concrete foundation stand with a nail.
[0041]
If it is set as the structure of Claim 4 , the operation | work which fixes a vibration-absorbing rubber material on a concrete foundation stand with a volt | bolt or a nail will become unnecessary, and the arrangement | positioning of a rubber-absorbing rubber material will be forgotten.
[0042]
According to the structure of claim 5 , since the draining plate is integrally formed with the ventilation plate, only the work of attaching the ventilation plate to the outer surface of the wooden base with a nail or a wood screw, the draining plate that has been separately attached at the same time is also simultaneously performed. It can be attached and workability is improved.
