Abstract

<P>PROBLEM TO BE SOLVED: To solve the problems of separation, insufficient strength, and lack of durability of leveling mortar for use in upper surface leveling, occurring when a wooden house is built according to a prevalent generic sill packing method which has a function of eliminating an error of the horizontality of the leveling mortar in the range of 6 mm and of underfloor ventilation, under the construction circumstances that an upper surface leveling step is known in the process of foundation construction for eliminating an entire horizontal error and a minute planar error on a concrete foundation upper surface of a wooden building, but in spite of execution of the step, the horizontal error of about 3 to 6 mm on a finished plane of the foundation upper surface and the minute error of the finished plane inevitably occur, execution of the upper surface leveling step requires a skilled technique and an execution time, which spends increased labor costs and costs for leveling mortar to achieve the horizontality, and the upper surface leveling step still includes technical problems of mortar separation and insufficient strength. <P>SOLUTION: There is provided a steel sill packing with a leveling and balancing function, which can minimize a sill upper surface error to a horizontality accuracy of 1 mm or less by carrying out simple work even if an error of a foundation upper surface constructed through a conventional method without including the upper surface leveling step, is considerably large. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、木造建築物のコンクリート基礎上の天端に敷設される木製土台との間に介装して使用し、コンクリート基礎天端の水平や仕上げ面のバラツキに影響される事なく、木製土台の天端の高さ及びバランスを簡易な作業によって、正確に施工できるレベル＆バランス機能付き鋼製土台パッキンに関する。 The present invention is used by interposing between a wooden base laid on the top of a concrete foundation of a wooden building, and without being affected by the level of the top of the concrete foundation or variations in the finished surface. The present invention relates to a steel foundation packing with a level & balance function that can accurately construct the height and balance of the top edge of the foundation by simple work.

木造建築物のコンクリート布基礎及びその他のコンクリート基礎と、当該これらのコンクリート基礎上に敷設される木製土台との間に介装して使用する木造建築物の土台下パッキンは、土台下に通気口として機能する隙間が確保されるため、コンクリート基礎に面する木製土台底面の腐食を防止し得るだけでなく、床下の換気効果が大きくなり、建物自体に好効果を及ぼすことが知られている。従来のこの種の土台下パッキンは、化学系の樹脂材料を使った長方形厚板状のものが多く使われている。
また、金属を用いて加工された通気を主体に考案されたものもある（例えば、特開平１０−２１９８５６参照。）。
特開平１０−２１９８５６号公報 The packing under the foundation of the wooden building used between the concrete cloth foundation of the wooden building and other concrete foundations and the wooden foundation laid on the concrete foundation is a vent hole under the foundation. It is known that not only can the corrosion of the bottom surface of the wooden base facing the concrete foundation be prevented, but also the ventilation effect under the floor is increased and the building itself has a positive effect. Conventionally, this type of under-packing packing has a rectangular plate shape made of a chemical resin material.
In addition, there is a device devised mainly by ventilation processed using metal (for example, see JP-A-10-211985).
Japanese Patent Laid-Open No. 10-219856

この種の土台下パッキンは床下の通気及び換気を主な目的に開発されたものであり、高さ調整も１〜６ｍｍと限られた範囲では可能であるが、微妙なバランス調整は不可能に近い状況である。また、ある程度の高さ調整はできるもののパッキン自体のバランス調整が殆んどできない等の問題を抱えていた。したがって同工法に於いては、コンクリート基礎天端の水平精度が許容範囲以内に満たされた状態のみ使用が可能であった。 This type of under-packing was developed mainly for underfloor ventilation and ventilation, and height adjustment is possible within a limited range of 1 to 6 mm, but delicate balance adjustment is impossible. The situation is near. In addition, although the height can be adjusted to some extent, the balance of the packing itself is hardly adjusted. Therefore, this method can be used only when the horizontal accuracy of the top of the concrete foundation is within an allowable range.

これらの土台下パッキンの適正な性能を発揮させるためには、コンクリート基礎の天端の水平度や平面度の仕上げの品質を上げなければならないという課題が残されている。このコンクリート基礎天端面仕上げの品質向上対策として、一般的なモルタルセメントやモルタルコンクリートを液状にした特殊なレベルモルタル等を使った、天端均し（てんばならし）作業が一般化している。しかし、これらの施工方法を用いてもコンクリート基礎天端の水平度及び平面度の仕上がり状況は不均等であり、また作業者の技術水準にも大きく影響されてしまう。 In order to exhibit the appropriate performance of these under-packing packings, there remains a problem that the finishing quality of the top and bottom of the concrete foundation must be improved. As a measure for improving the quality of the concrete foundation top end surface, a general mortar cement or a special level mortar made of mortar concrete in a liquid state is generally used. However, even if these construction methods are used, the level of flatness and flatness of the concrete foundation top end are not uniform and are greatly affected by the technical level of the operator.

モルタルセメントやレベルモルタル等を使いコンクリート基礎天端の水平度及び平面度を仕上げる、天端均し工法に於いては、同レベルモルタル等の剥離現象や強度不足という問題が少なからぬ状況で起きるため、建築物の品質や耐久性に対し必ずしも芳しい状況とはいえなかった。 In the top edge leveling method, which uses mortar cement or level mortar to finish the level and flatness of the top of the concrete foundation, there are not a few problems such as peeling phenomenon and insufficient strength of the same level mortar. It was not always a good situation for the quality and durability of the building.

また、同施工方法ではレベルモルタル材を使うための材料費や、同天端均し作業に掛かる人件費のコストの増大を伴った。当該これらの施工方法を行ってもコンクリート製基礎天端の水平度及び平面度の仕上がり状況の一定化は非常に難しい状態である。 In addition, the construction method was accompanied by an increase in material costs for using level mortar materials and labor costs for the same leveling work. Even if these construction methods are carried out, it is very difficult to make the finished state of the levelness and flatness of the concrete base top end very constant.

現状の建築現場に於いて、同コンクリート基礎天端仕上がり状況のもと、木製土台天端の水平度もコンクリート基礎天端仕上がりに比例してかなりの誤差が生じてしまう。当該木製土台の水平精度欠落のまま、木工事が次工程で修正施工が進められているという課題があった。 In the current construction site, the level of horizontalness of the top of the wooden foundation also causes a considerable error in proportion to the finish of the top of the concrete foundation. There was a problem that the wooden work was being corrected in the next process while the horizontal accuracy of the wooden base was lacking.

上記のような従来の土台下パッキンでは、現状の基礎コンクリート天端での、基礎全体の大きな水平誤差や、且つ天端仕上がり面の部分的なごく微妙な水平誤差など、多様な水平面誤差のバラツキが基礎コンクリート天端に生じるため、木製土台の天端の水平度を正確に出すのに大変な労力と技術を必要としていた。したがって木製土台の天端レベルに大きな誤差を残したまま、次工程の土台と根太間にパッキンを入れ調整するなど、応急処置的な施工を行うため、次に連鎖する工程に於いてさらなる影響を受け、そのつど手直し調整の労力がかかっていた。当該建築物そのものに品質上の問題も起きていた。 With the conventional under-packing packing as described above, there are a variety of horizontal surface error variations such as the large horizontal error of the entire foundation at the top of the current foundation concrete and the very slight horizontal error of the top finished surface. Since this occurs at the top of the foundation concrete, a great deal of labor and skill was required to accurately determine the level of the top of the wooden foundation. Therefore, while maintaining a large error in the top level of the wooden base, it is necessary to make an emergency treatment such as packing between the base and joist in the next process and adjust it. As a result, it took time to make adjustments. There was also a quality problem in the building itself.

その他、現状の基礎工法の生コンクリート打設工事に於いては、基礎天端の水平誤差や仕上がり面の不均一が生じるため直後に、天端均し作業が常識化していた。しかし同工程で使われるレベルモルタルの剥離や強度不足等の品質問題があり、当該天端均し作業の改善もしくは省略化は確たる必要性に迫られていた。 In addition, in the current concrete casting work of the foundation method, the horizontal error at the top of the foundation and the unevenness of the finished surface occur, and immediately after that, the top leveling work became common sense. However, there are quality problems such as peeling of the level mortar used in the same process and lack of strength, and there has been an urgent need to improve or eliminate the top leveling work.

本発明はコンクリート基礎工事に於いて、生コンクリート打設による基礎天端を天端均し作業を省略した状態での基礎天端１９aの水平誤差や仕上がり面の状態が不均一で、天端表面の仕上がりが粗い状態にあっても、木製土台２１の天端レベル及びバランス調整をより正確に簡易作業に於いてできる手段として考案したものである。この天端均しを省いたコンクリート基礎天端１９aに於いて、コンクリート基礎と木製土台の間に用いる部材であって、鋼製土台パッキンプレート部１１の底面側に3箇所及び複数のナット１３付支持用突起部１２と、基礎と土台の隙間の違いに応じて数種類の長さの調整用ボルト１４a〜１４dを選定し、前記鋼製土台パッキンプレート部の底面側突起部のナット１３に、その場所に合った長さを持つ前記調整用ボルト１４a〜１４dを選定し、挿入ねじ込みし微妙な調節ができる。当該木造建築物の基礎が床下に入れる構造であれば工事途中及び竣工後に於いても、木製土台の水平高さ及びバランス調整が簡単な作業によってできる。レベル＆バランス機能付き鋼製土台パッキン。 In the present invention, in the foundation work of the concrete, the horizontal error of the foundation top end 19a and the finished surface are not uniform in the state where the top end of the foundation by placing the ready-mixed concrete is omitted, and the surface of the top end is not uniform. Even if the finish is rough, the top level and balance of the wooden base 21 are devised as a means that can be more accurately and easily adjusted. In the concrete foundation top end 19a from which the top edge leveling is omitted, it is a member used between the concrete foundation and the wooden base, and is provided with three nuts 13 on the bottom surface side of the steel base packing plate portion 11. Several types of adjustment bolts 14a to 14d having different lengths are selected according to the difference between the support protrusion 12 and the gap between the foundation and the base, and the nut 13 on the bottom side protrusion of the steel base packing plate portion The adjustment bolts 14a to 14d having a length suitable for the place are selected, and can be finely adjusted by inserting the bolts. If the foundation of the wooden building is placed under the floor, the horizontal height and balance of the wooden base can be adjusted by simple work even during and after the construction. Steel base packing with level & balance function.

前記鋼製土台パッキンプレート部の底面側ナット付突起部１２は、螺子下長さ１５ｍｍ及びその他の長さ２０〜３０ｍｍの調整ボルトが、土台レベル調整のためナットを貫通しねじ込まれた状態に於いて、各調整ボルト１４a〜１４dが６ｍｍ程度までの高さ調整のためのナット部１３を越えた時に必要とする空隙を有する。よって各調整用ボルト１４a〜１４dのネジヤマ掛部分が少なくなる取り付けを防ぐ事ができ、耐荷重を損なう事なくして６ｍｍ前後の高さ調整ができる前項に記載の木造建築物に於ける、木製土台の水平精度が耐荷重強度を損なうことなく、より簡単な作業で施工できる。レベル＆バランス機能付き鋼製土台パッキン。 The bottom-side protrusion 12 with a nut on the bottom surface of the steel base packing plate portion is in a state in which adjustment bolts having a screw lower length of 15 mm and other lengths of 20 to 30 mm are screwed through the nut for adjusting the base level. In addition, each adjustment bolt 14a to 14d has a gap required when it exceeds the nut portion 13 for height adjustment up to about 6 mm. Therefore, it is possible to prevent the adjustment bolts 14a to 14d from being attached with less screw parts, and to adjust the height of about 6 mm without impairing the load bearing capacity. The horizontal accuracy of can be installed in a simpler work without impairing the load bearing strength. Steel base packing with level & balance function.

前記鋼製土台パッキンプレート部の底面側の突起部ナット１３及び、調整用ボルト螺子下長さ１５ｍｍ１４aによって、高さ及びバランス調整を２０ｍｍ〜２６ｍｍの範囲で微調整できる。該調整用ボルト螺子下長さを２０ｍｍ１４ｂ或は２５ｍｍ１４ｃそして３０ｍｍ１４ｄと５ｍｍ単位の長さで変更交換することによって、２０ｍｍ〜３６ｍｍ程度の範囲に於いて微調整できる。また、これ以外の調整ボルトの螺子下長さを変更する事で、その範囲以上にも対応し、微調整ができるように構成されている。よって、柱２２の直下や土台のつなぎ目２１b、アンカーボルト部２０の限られた範囲の、コンクリート基礎天端１９aの表面仕上げの粗さや水平誤差が大きな状態にあっても、木造建築物の土台２１のバランス調整と土台天端２１aの水平精度が簡易作業によって微調整ができるレベル＆バランス機能付き鋼製土台パッキン。 The height and balance adjustment can be finely adjusted in the range of 20 mm to 26 mm by the protrusion nut 13 on the bottom side of the steel base packing plate portion and the adjustment bolt screw lower length 15 mm 14 a. By changing and changing the adjustment bolt screw length under 20 mm14b or 25 mm14c and 30 mm14d in units of 5 mm, fine adjustment can be made in the range of about 20 mm to 36 mm. In addition, by changing the under screw length of the adjustment bolt other than the above, it is possible to make fine adjustment corresponding to the range or more. Therefore, even if the surface finish roughness and horizontal error of the concrete foundation top end 19a within a limited range of the column 22 and the base joint 21b and the anchor bolt portion 20 are large, the base 21 of the wooden building Steel foundation packing with level & balance function that can fine-tune the balance adjustment and horizontal accuracy of the base top 21a by simple work.

本発明は、上記のような従来の問題点である基礎天端均し作業が省けるため、該天端均しに使われるレベルモルタルの剥離及び強度や耐久性の問題を解消できる。 The present invention eliminates the above-mentioned conventional basic top end leveling operation, and thus can solve the problems of peeling, strength and durability of the level mortar used for the top end leveling.

また、コンクリート基礎天端１９aの凹凸などに関わらず、レベル＆バランス機能付き鋼製土台パッキンが建築物から受ける荷重に対して平衡に受けられるため、建物本体の荷重が分散され、特定箇所に偏った負担がかからない構成となっている。 Regardless of the unevenness of the concrete foundation top 19a, the steel base packing with level and balance function is balanced against the load received from the building, so the load on the building body is distributed and biased to a specific location It has a structure that does not require a heavy burden.

上記のように基礎コンクリート天端１９aの水平及び平坦度のばらつきがかなり悪い状態でも、木造建築物の木製土台２１のバランスを整え、当該いままで不可能であった全体の水平精度を１ｍｍ以内のレベル誤差まで容易にして解決し得る、レベル＆バランス機能付きの鋼製土台パッキン１０を提供することを目的とするものである。 Even when the horizontal and flatness variations of the foundation concrete top 19a are considerably poor as described above, the balance of the wooden base 21 of the wooden building is adjusted, and the overall horizontal accuracy which has been impossible until now is within 1 mm. An object of the present invention is to provide a steel base packing 10 with a level & balance function that can be easily solved even for level errors.

以下、本発明の実施の形態を図１〜図９に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to FIGS.

その手段を後述する実施形態の参照符号を付して示すと、鋼製土台パッキンプレート部１１の底面側に複数の支持用突起部１２と、その突起部に密着した複数のナット１３と調整用ボルト１４a〜１４ｄを設けた図１〜図２に示す、レベル＆バランス機能付き鋼製土台パッキン１０である。前記突起部に密着した複数のナット１３は、調整用ボルト１４aの螺子下長さ１５ミリを標準として、基礎コンクリート天端高さのバラツキに応じ、螺子下長さ２０〜３０ミリ程度の調整用ボルト１４ｂ〜１４ｄを選定し図９に示すように挿入する。それぞれの調整用ボルトは螺子回転による微妙な高さを調節できるレベル＆バランス機能付き鋼製土台パッキン。 When the means is shown with reference numerals of the embodiments described later, a plurality of supporting projections 12 on the bottom side of the steel base packing plate portion 11, a plurality of nuts 13 closely attached to the projections, and an adjustment It is the steel base packing 10 with a level & balance function shown in FIGS. 1-2 provided with the bolts 14a-14d. The plurality of nuts 13 that are in close contact with the protrusions are for adjustment with a screw lower length of about 20 to 30 mm according to variations in the height of the foundation concrete top end, with the screw lower length of the adjustment bolt 14a being 15 mm as a standard. Bolts 14b to 14d are selected and inserted as shown in FIG. Each adjustment bolt is a steel base packing with level & balance function that can adjust the delicate height by rotating the screw.

上記の本発明木造建築物のレベル＆バランス機能付き鋼製土台パッキン１０を実施するに際し、図５に示すようにコンクリート基礎１９の側面或は水平墨１８を墨付けできる場所を選定し水平墨１８を正確に印す。この時、水盛管を用いる事でより正確な水平墨が確保される。また、図６に示すように柱２２の立つ位置及び図８に示す土台のつなぎ目２１a、図７に示したアンカーボルト２０の位置を確認の上、水平墨とレベル＆バランス機能付き鋼製土台パッキン１０が取り付く各位置のコンクリート天端の高さを測定し、その高さにあった調整用ボルト１４a〜１４ｄを選定する。 When the above-described steel base packing 10 having a level & balance function of the wooden building according to the present invention is carried out, a side surface of the concrete foundation 19 or a place where the horizontal ink 18 can be inked is selected as shown in FIG. Is accurately marked. At this time, a more accurate horizontal ink can be secured by using a water pipe. Further, after confirming the position where the pillar 22 stands as shown in FIG. 6, the position of the base joint 21a shown in FIG. 8, and the position of the anchor bolt 20 shown in FIG. The height of the top of the concrete at each position where 10 is attached is measured, and the adjusting bolts 14a to 14d corresponding to the height are selected.

基準墨１８とレベル＆バランス機能付き鋼製土台パッキン１０を取り付ける各位置のコンクリート天端１９aの高さ、即ち基礎１９と土台２１の隙間誤差を把握の上、鋼製土台パッキンプレート部１１の底面側突起部ナット１３に、調整用ボルト１４a〜１４ｄ螺子下長さ１５ミリ〜３０ミリを基礎と土台の隙間に合わせ選定しねじ込む。該木製土台２１の底辺部に鋼製土台パッキンプレート部１１の楔１６又は、釘穴１７から釘を撃ち付け木製土台２１の底辺部に固定する。この時アンカーボルト２０については、図７の取り付け図に示すように、鋼製土台パッキンプレート部１１の三角穴１５にアンカーボルトを入れ基礎天端１９aに据えつける。 The bottom surface of the steel foundation packing plate portion 11 is obtained by grasping the height of the concrete top edge 19a at each position where the reference ink 18 and the steel foundation packing 10 with the level & balance function are attached, that is, the gap error between the foundation 19 and the foundation 21. The adjusting bolts 14a to 14d have a length 15 mm to 30 mm below the adjusting bolts 14a to 14d in accordance with the gap between the foundation and the base, and are screwed into the side protrusion nut 13. A nail is shot from the wedge 16 or the nail hole 17 of the steel base packing plate portion 11 to the bottom side of the wooden base 21 and fixed to the bottom side of the wooden base 21. At this time, with respect to the anchor bolt 20, as shown in the attachment diagram of FIG. 7, the anchor bolt is inserted into the triangular hole 15 of the steel base packing plate portion 11 and installed to the base top end 19a.

次に、各所定箇所にレベル＆バランス機能付き鋼製土台パッキン１０を取り付けた木製土台２１をコンクリート基礎１９上に配置して固定する。この時、コンクリート基礎天端１９aの一番高いところを基準に、調整ボルト１４aを取り付けたレベル＆バランス機能付き鋼製土台パッキン１０は、調整ボルト１４aを支持用突起部接合ナット１３に締め込み一番低くした状態でバランスを取りながらセットする。この高さを基準として、各所定箇所の取り付けたレベル＆バランス機能付き鋼製土台パッキン１０の各種調整ボルト１４a〜１４dを選定し微調整する事で、コンクリート基礎天端１９aの水平誤差や仕上がり状況が粗い状態であっても、簡易作業によって木製土台天端２１aの水平を１ｍｍ以内の誤差に収める事ができる。 Next, the wooden base 21 with the steel base packing 10 with level & balance function attached to each predetermined place is placed on the concrete foundation 19 and fixed. At this time, the steel base packing 10 with the level & balance function to which the adjustment bolt 14a is attached is based on the highest point of the concrete foundation top 19a. Set the balance while keeping the balance low. Using this height as a reference, selecting and fine-adjusting the various adjustment bolts 14a to 14d of the steel base packing 10 with level & balance function installed at each predetermined location, the horizontal error and finish of the concrete foundation top 19a Even in a rough state, the horizontal position of the wooden base top 21a can be kept within an error of 1 mm or less by a simple operation.

また、土台２１の敷設に於いて水平とバランスを正確に出したにも拘らず、建築進捗状況によって土台上にかかる建築物荷重はかなりの変化をもたらす事が予想される。これらの変化によって、木製土台天端２１aの水平に誤差が生じる可能性は大きい。しかし、レベル＆バランス機能付き鋼製パッキン１０は工事途中、或は完成後に於いても床下に入れる基礎構造であれば、図９に示す各調整ボルト１４a〜１４dを一般用スパナで回転による各調整によって、水平及びバランス調整が簡単に行える。 Moreover, despite the fact that the horizontal and balance are accurately obtained in the laying of the base 21, it is expected that the building load applied on the base will cause a considerable change depending on the progress of the construction. Due to these changes, there is a high possibility that an error will occur horizontally in the wooden base top 21a. However, if the steel packing 10 with level & balance function is a foundation structure that can be put under the floor even during construction or after completion, each adjustment bolt 14a-14d shown in FIG. 9 is adjusted by rotation with a general spanner. Can easily adjust the horizontal and balance.

In addition, each adjustment bolt 14a to 14d has a gap required when it exceeds the nut portion 13 for height adjustment up to about 6 mm. Therefore, it is possible to prevent the adjustment bolts 14a to 14d from being attached with less screw parts, and to adjust the height of about 6 mm without impairing the load bearing capacity. Steel base packing with level & balance function that can be installed in a simpler way without compromising the load bearing strength. 前記鋼製土台パッキンプレート部の底面側の突起部ナット１３及び、調整用ボルト螺子下長さ１５ｍｍ１４aによって、高さ及びバランス調整を２０ｍｍ〜２６ｍｍの範囲で微調整できる。該調整用ボルト螺子下長さを２０ｍｍ１４ｂ或は２５ｍｍ１４ｃそして３０ｍｍ１４ｄと５ｍｍ単位の長さで変更交換することによって、２０ｍｍ〜３６ｍｍ程度の範囲に於いて微調整できる。また、これ以外の調整ボルトの螺子下長さを変更する事で、その範囲以上にも対応し、微調整ができるように構成されている。よって、柱２２の直下や土台のつなぎ目２１b、アンカーボルト部２０の限られた範囲の、コンクリート基礎天端１９aの表面仕上げの粗さや水平誤差が大きな状態にあっても、木造建築物の土台２１のバランス調整と土台天端２１aの水平精度が簡易作業によって微調整ができるレベル＆バランス機能付き鋼製土台パッキン。 The height and balance adjustment can be finely adjusted in the range of 20 mm to 26 mm by the protrusion nut 13 on the bottom side of the steel base packing plate portion and the adjustment bolt screw lower length 15 mm 14 a. By changing and changing the adjustment bolt screw length under 20 mm14b or 25 mm14c and 30 mm14d in units of 5 mm, fine adjustment can be made in the range of about 20 mm to 36 mm. In addition, by changing the under screw length of the adjustment bolt other than the above, it is possible to make fine adjustment corresponding to the range or more. Therefore, even if the surface finish roughness and horizontal error of the concrete foundation top end 19a within a limited range of the column 22 and the base joint 21b and the anchor bolt portion 20 are large, the base 21 of the wooden building Steel foundation packing with level & balance function that can fine-tune the balance adjustment and horizontal accuracy of the base top 21a by simple work.
