Description

本発明は、下地とその表面に形成された防水層とを有する設置部位に設置されるアンカー具、及び、このアンカー具の設置構造に関するものである。 The present invention relates to an anchor tool installed at an installation site having a base and a waterproof layer formed on the surface thereof, and an installation structure of the anchor tool.

建物の屋上に太陽光発電設備等の構造物を設置する場合、雨、風、地震等に耐え得る確実な固定手段が求められる。それには、構造物と屋上の床部とをアンカーボルトで機械的に固定するのが一般的である。ここで、屋上の床部を構成するコンクリート等の下地に、防水シートや防水塗料等で防水層が設けられている場合がある。このような防水層を有する設置部位にアンカーボルトを打設すると、防水層に貫通孔を形成することとなり、この部分で防水層の防水機能が損なわれる。 When installing a structure such as a photovoltaic power generation facility on the roof of a building, a reliable fixing means that can withstand rain, wind, earthquake, etc. is required. For that purpose, it is common to mechanically fix the structure and the floor of the roof with anchor bolts. Here, a waterproof layer may be provided with a waterproof sheet, a waterproof paint, or the like on a base such as concrete constituting the floor of the roof. When an anchor bolt is placed in an installation portion having such a waterproof layer, a through hole is formed in the waterproof layer, and the waterproof function of the waterproof layer is impaired at this portion.

上記のような背景から、防水層を有する床部に対しては、アンカーボルトを予め一体的に設けたプレートやコンクリートブロック等を接着剤で直接固着する工法が採用されることがある。 From the above background, a method of directly fixing a plate or a concrete block in which anchor bolts are integrally provided in advance with an adhesive may be adopted for the floor portion having a waterproof layer.

或いは、防水層を有する床部にアンカーボルトを打設した後、防水層の貫通部分をコーキング材で防水処理する工法が採用されることもある。 Alternatively, a method may be adopted in which anchor bolts are placed on the floor having a waterproof layer and then the penetrating portion of the waterproof layer is waterproofed with a caulking material.

又、特許文献１には、次のような基礎用あと施工アンカーが記載されている。コンクリート等の下地に固定した定着用アンカーの雄ねじ部に、筒状ベース部品の雌ねじ孔を螺合させ、筒状ベース部品の先端側にハット部材を載せる。そして、ハット部材の天板部の穴を通して筒状ベース部品の雌ねじ孔に設置物固定用ボルトをねじ込み、筒状ベース部品の先端面と設置物固定用ボルトの回転操作部との間にハット部材を挟んで締め付けることで、ハット部材の接地板部を下地の表面に接地させた状態に固定する。その後、設置物固定用ボルトの突出ボルト部にカバー部材を外挿し、突出ボルト部に螺着したナットと回転操作部との間にカバー部材を挟んで締め付けることで、カバー部材がハット部の先端側を覆うように固定される。この基礎用あと施工アンカーによれば、組み立てが簡単であり、コンクリートの下地に穿設する下穴の大きさを、定着用アンカーを定着し得る最小限の大きさとすることができ、定着用アンカーを定着させる下穴を、筒状ベース部品、ハット部材及びカバー部材で覆うだけなので、施工箇所廻りの防水処理を簡単に短時間で効率良く行える、とされている（特許請求の範囲、発明の効果参照）。 Further, Patent Document 1 describes the following post-installed foundation anchors. The female screw hole of the tubular base part is screwed into the male screw part of the fixing anchor fixed to the base such as concrete, and the hat member is placed on the tip side of the tubular base part. Then, the installation object fixing bolt is screwed into the female screw hole of the tubular base component through the hole in the top plate portion of the hat member, and the hat member is placed between the tip surface of the tubular base component and the rotation operation portion of the installation object fixing bolt. By sandwiching and tightening, the grounding plate portion of the hat member is fixed in a state of being grounded to the surface of the base. After that, the cover member is externally inserted into the protruding bolt part of the bolt for fixing the installation object, and the cover member is sandwiched between the nut screwed to the protruding bolt part and the rotation operation part and tightened, so that the cover member is the tip of the hat part. It is fixed so as to cover the side. According to this post-installed foundation anchor, it is easy to assemble, and the size of the pilot hole drilled in the concrete base can be set to the minimum size that can fix the anchor for fixing, and the anchor for fixing can be fixed. Since the prepared hole for fixing the concrete is simply covered with a tubular base part, a hat member and a cover member, it is said that waterproofing treatment around the construction site can be performed easily and efficiently in a short time (claims, invention). See effect).

Ａ）構造物に風や地震等により水平方向の負荷が作用した場合、防水層に剥離力、剪断力が作用し、防水層を破損するおそれがある。
Ｂ）構造物の自重及び構造物に作用する荷重がプレートやコンクリートブロック等を介して防水層に直接作用することで、防水層が損傷するおそれがある。
Ｃ）アンカーボルトと比較すると、接着剤による固着は、引っ張り力や剪断力に対する強度を得るのが困難であるうえ、コスト及び工期がかかる。 The method of directly fixing a plate or concrete block integrated with an anchor bolt to a waterproof layer with an adhesive has the following problems.
A) When a horizontal load acts on the structure due to wind, earthquake, etc., peeling force and shearing force act on the waterproof layer, which may damage the waterproof layer.
B) The weight of the structure and the load acting on the structure act directly on the waterproof layer via the plate, concrete block, etc., which may damage the waterproof layer.
C) Compared with anchor bolts, fixing with an adhesive makes it difficult to obtain strength against tensile force and shearing force, and also requires cost and construction period.

一方、防水層におけるアンカーボルトを打設した箇所をコーキング材で防水処理する工法には、次のような問題がある。
Ｄ）アンカーボルトのねじ部の谷底までコーキング材を充填するのが難しいため、ねじ部の溝を伝って下地に漏水する可能性がある。
Ｅ）防水層との相性によってはコーキング材の付着力が不足して、漏水を招く可能性がある。
Ｆ）構造物が風や地震等により変位を生じたとき、アンカーボルトにも変位が発生し、その結果、コーキング材の割れや接着界面での剥離が発生して、防水性能が損なわれるおそれがある。 On the other hand, there are the following problems in the method of waterproofing the place where the anchor bolt is placed in the waterproof layer with a caulking material.
D) Since it is difficult to fill the valley bottom of the threaded portion of the anchor bolt with the caulking material, water may leak to the base along the groove of the threaded portion.
E) Depending on the compatibility with the waterproof layer, the adhesive force of the caulking material may be insufficient, leading to water leakage.
F) When the structure is displaced due to wind, earthquake, etc., the anchor bolts are also displaced, and as a result, the caulking material may crack or peel off at the adhesive interface, and the waterproof performance may be impaired. be.

Block. Further, since the first screw hole portion and the second screw hole portion do not communicate with each other, water flow in this portion is blocked. Therefore, it is possible to prevent water from entering the base without allowing water to reach the place where the waterproof function of the waterproof layer is lost by erecting the lower bolt member at the installation site. ..

請求項６記載の発明によれば、アンカー具のナット部材の周面と第２のシール部材の第２のスリーブ部との間が水密的に閉塞されると共に、第２のフランジ部と防水層との間が水密的に閉塞される。又、第１のねじ孔部と第２のねじ孔部とは非連通なので、この部分での通水が阻止される。従って、設置部位における下側ボルト部材を立設させて防水層の防水機能が失われた箇所に外部から水を到達させることがないから、下地に水を浸入させることのないアンカー具の設置構造を提供できる。アンカー具は、ナット部材を下側ボルト部材に螺合して固定する構造なので、設置及び取り外しが容易である。又、アンカー具と防水層とが力学的に独立する構造となるから、アンカー具に荷重が作用したときに、防水層に剥離力や剪断力が作用しにくくなる。 According to the sixth aspect of the present invention, the peripheral surface of the nut member of the anchor tool and the second sleeve portion of the second sealing member are watertightly closed, and the second flange portion and the waterproof layer are closed. The space between and is closed watertightly. Further, since the first screw hole portion and the second screw hole portion do not communicate with each other, water flow in this portion is blocked. Therefore, since water does not reach the place where the waterproof function of the waterproof layer is lost by erecting the lower bolt member at the installation site, the installation structure of the anchor tool that does not allow water to enter the base. Can be provided. Since the anchor tool has a structure in which the nut member is screwed and fixed to the lower bolt member, it is easy to install and remove. Further, since the anchor tool and the waterproof layer have a mechanically independent structure, it becomes difficult for a peeling force or a shearing force to act on the waterproof layer when a load is applied to the anchor tool.

本実施の形態のアンカー具及びその設置構造は、例えば建築物の屋上等において、躯体を構成するコンクリートの下地１の表面に防水層２が形成された設置部位Ｒに、太陽光発電装置、ウッドデッキ、貯水槽等の各種構造物を設置するための固定手段として用いられるものである。 The anchor tool and its installation structure of the present embodiment are, for example, on the rooftop of a building, in an installation portion R where a waterproof layer 2 is formed on the surface of a concrete base 1 constituting the skeleton, a photovoltaic power generation device, and a wood deck. , It is used as a fixing means for installing various structures such as a water tank.

図面を参照して、アンカー具１０は、少なくとも上端側に雄ねじが形成されたねじ部１２を有し、下端側に下地１に埋設されるアンカー部１３を有する固定部材１１と、ねじ部１２及びアンカー部１３を露出させた状態で固定部材１１の周面を水密的に覆う第１のスリーブ部１５及び第１のスリーブ部１５の下端に固定部材１１の周囲に広がるように設けられ防水層２に水密的に接着可能なシート状の第１のフランジ部１６を有する第１のシール部材１４とを備える。 With reference to the drawings, the anchor tool 10 has a fixing member 11 having a threaded portion 12 having a male screw formed at least on the upper end side and an anchor portion 13 embedded in the base 1 on the lower end side, a threaded portion 12, and a threaded portion 12. The waterproof layer 2 is provided at the lower ends of the first sleeve portion 15 and the first sleeve portion 15 that watertightly covers the peripheral surface of the fixing member 11 with the anchor portion 13 exposed so as to spread around the fixing member 11. A first sealing member 14 having a sheet-like first flange portion 16 that can be watertightly adhered to the surface is provided.

本例では、固定部材１１として、全長に雄ねじを形成した全ねじボルト（寸切りボルトとも言う）が使用される。第１のシール部材１４の材質としては弾性と防水性とを有するものが採用され、例えばゴムや樹脂素材、アスファルトルーフィング等が使用される。第１のスリーブ部１５を固定部材１１に水密的に設ける手段としては、加硫接着が用いられる。加硫接着によれば、第１のスリーブ部１５で固定部材１１のねじ溝を谷底まで充填することができるので、第１のスリーブ部１５と固定部材１１との間の隙間がなくなり、確実な止水性能を発揮することができる。 In this example, as the fixing member 11, a full-threaded bolt (also referred to as a shredded bolt) having a male screw formed over the entire length is used. As the material of the first sealing member 14, a material having elasticity and waterproofness is adopted, and for example, rubber, a resin material, asphalt roofing, or the like is used. Vulcanization adhesion is used as a means for watertightly providing the first sleeve portion 15 on the fixing member 11. According to the vulcanization adhesion, since the thread groove of the fixing member 11 can be filled up to the valley bottom by the first sleeve portion 15, there is no gap between the first sleeve portion 15 and the fixing member 11, and the fixing member 11 is surely filled. It can demonstrate water stopping performance.

このアンカー具１０を施工するには、設置部位Ｒの所定領域において防水層２の一部を除去して下地１を露出させた箇所３を形成し、ここに下穴４を穿設する。この時、防水層２を除去する範囲は、第１のフランジ部１６で覆い隠すことができ、且つ、第１のフランジ部１６と防水層２とが接着する範囲を十分確保できるように設定する。そして、穿設した下穴４にアンカー部１３を埋設して、アンカー具１０の固定部材１１を起立状態に固定すると共に、第１のフランジ部１６を防水層２の表面に水密的に接着する。アンカー部１３を下穴４内に定着させる手段には、例えば短時間で硬化する合成樹脂を用いたケミカルアンカー（登録商標）や、打ち込み式等の金属系アンカーを状況に応じて使用することができる。第１のフランジ部１６を防水層２に接着するための接着剤は、両者の材質を考慮して、接着性能の優れたものが選択される。 In order to construct the anchor tool 10, a part 3 of the waterproof layer 2 is removed to form a portion 3 in which the base 1 is exposed in a predetermined area of the installation portion R, and a pilot hole 4 is formed therein. At this time, the range in which the waterproof layer 2 is removed can be covered by the first flange portion 16, and the range in which the first flange portion 16 and the waterproof layer 2 adhere to each other can be sufficiently secured. .. Then, the anchor portion 13 is embedded in the drilled pilot hole 4, the fixing member 11 of the anchor tool 10 is fixed in an upright state, and the first flange portion 16 is watertightly adhered to the surface of the waterproof layer 2. .. As a means for fixing the anchor portion 13 in the prepared hole 4, for example, a chemical anchor (registered trademark) using a synthetic resin that cures in a short time or a metal anchor such as a driving type can be used depending on the situation. can. As the adhesive for adhering the first flange portion 16 to the waterproof layer 2, an adhesive having excellent adhesive performance is selected in consideration of the materials of both.

このようにして設置されたアンカー具１０は、上端側のねじ部１２を利用することで、所望の構造物を設置部位Ｒに固定することが可能となる。又、固定部材１１の周面と第１のスリーブ部１５との間が水密的に閉塞されると共に、第１のフランジ部１６と防水層２との間も水密的に閉塞されるので、設置部位Ｒにおける下地１を露出させて防水層２の防水機能が失われた箇所３に外部から水を到達させることがない。固定部材１１の周面と第１のスリーブ部１５との間、及び、第１のフランジ部１６と防水層２との間の接着面積を広く取れるので、高い水密性が得られるから下地１に水が浸入するおそれを無くすことができる。 The anchor tool 10 installed in this way can fix a desired structure to the installation portion R by using the screw portion 12 on the upper end side. Further, the peripheral surface of the fixing member 11 and the first sleeve portion 15 are watertightly closed, and the first flange portion 16 and the waterproof layer 2 are also watertightly closed. Water does not reach the portion 3 where the waterproof function of the waterproof layer 2 is lost by exposing the base 1 in the portion R from the outside. Since a wide adhesive area can be obtained between the peripheral surface of the fixing member 11 and the first sleeve portion 15 and between the first flange portion 16 and the waterproof layer 2, high watertightness can be obtained, so that the base 1 can be used. The risk of water intrusion can be eliminated.

又、アンカー具１０と防水層２とは、力学的に独立する構造となっている。それと同時に、アンカー部１３の周囲は防水層２が除去されて第１のフランジ部１６が防水層２に接着されない領域となっており、この領域を変位吸収部材として機能させることができる。このため、構造物からの荷重が防水層２に直接作用することが無く、しかも構造物から作用する荷重でアンカー具１０に変位が生じたとしても、防水層２に剥離力や剪断力が作用しにくくなるため、安定した止水性能が得られる。又、万一、過大な外力が作用してアンカー具１０が破損するような場合でも、防水層２に及ぼす影響を限定的なものにすることが可能である。 Further, the anchor tool 10 and the waterproof layer 2 have a mechanically independent structure. At the same time, the periphery of the anchor portion 13 is a region where the waterproof layer 2 is removed and the first flange portion 16 is not adhered to the waterproof layer 2, and this region can function as a displacement absorbing member. Therefore, the load from the structure does not directly act on the waterproof layer 2, and even if the anchor tool 10 is displaced by the load acting from the structure, the peeling force and the shearing force act on the waterproof layer 2. Since it is difficult to do so, stable water stopping performance can be obtained. Further, even if the anchor tool 10 is damaged by an excessive external force, the influence on the waterproof layer 2 can be limited.

尚、本例のアンカー具は、ボルト部材に対するシート部材の加硫接着を予め工場で行うことにより、防水性能に対する信頼性が高い製品を提供できる。又、防水層の材質を考慮してシート部材の材質を選択することにより、防水層に悪影響を及ぼすことなく、高い接着力を得ることが可能となる。 The anchor tool of this example can provide a product with high reliability in waterproof performance by vulcanizing and adhering the sheet member to the bolt member in advance at the factory. Further, by selecting the material of the sheet member in consideration of the material of the waterproof layer, it is possible to obtain high adhesive strength without adversely affecting the waterproof layer.

FIG. 4 relates to a second embodiment of the present invention, (A) is a cross-sectional view showing the installation site and the anchor tool separately, and FIG. 4 (B) shows the anchor tool installed at the installation site. It is sectional drawing which shows the situation.

本例は、第１の実施の形態と同種のアンカー具１０を固定する手段として、下地１に埋設した埋め込みナット１７を使用するものである。即ち、下地１における防水層２の一部を除去した箇所３に形成した下穴５に埋め込みナット１７を予め埋設し、これに固定部材１１のアンカー部１３の雄ねじを螺合させることで、ねじ部１２が起立状態となるように固定部材１１を固定することができる。 In this example, an embedded nut 17 embedded in the base 1 is used as a means for fixing the anchor tool 10 of the same type as that in the first embodiment. That is, the embedded nut 17 is embedded in advance in the prepared hole 5 formed in the portion 3 where the waterproof layer 2 is partially removed in the base 1, and the male screw of the anchor portion 13 of the fixing member 11 is screwed into the embedded nut 17 to screw the screw. The fixing member 11 can be fixed so that the portion 12 is in an upright state.

本例のアンカー具１０の設置構造によれば、固定部材１１を埋め込みナット１７に螺合させて固定するので、アンカー具１０の設置作業が容易である。又、アンカー具１０の取り外しも容易に行えるので、必要に応じ、アンカー具１０の交換や仕様変更を簡単に行うことができる。 According to the installation structure of the anchor tool 10 of this example, since the fixing member 11 is screwed and fixed to the embedded nut 17, the installation work of the anchor tool 10 is easy. Further, since the anchor tool 10 can be easily removed, the anchor tool 10 can be easily replaced or the specifications can be changed as needed.

FIG. 5 relates to a third embodiment of the present invention, and FIG. 5A is a cross-sectional view showing the installation site and the anchor tool separately. (B) is a cross-sectional view showing a situation in which the anchor tool is installed at the installation site.

本例のアンカー具２０は、下端面部に雌ねじが形成された第１のねじ孔部２２を有し、上端面部に雌ねじが形成された第２のねじ孔部２３を有し、第１のねじ孔部２２と第２のねじ孔部２３とが連通しないように構成した柱状のナット部材２１と、ナット部材２１の周面を水密的に覆う第２のスリーブ部２５及び第２のスリーブ部２５の下端にナット部材２１の周囲に広がるように設けられ防水層２に水密的に接着可能なシート状の第２のフランジ部２６を有する第２のシール部材２４とを備えるものである。ナット部材２１に第２のスリーブ部２５を水密的に設ける手段としては加硫接着が使用される。 The anchor tool 20 of this example has a first screw hole portion 22 in which a female screw is formed on a lower end surface portion, a second screw hole portion 23 in which a female screw is formed on an upper end surface portion, and a first screw. A columnar nut member 21 configured so that the hole portion 22 and the second screw hole portion 23 do not communicate with each other, and a second sleeve portion 25 and a second sleeve portion 25 that watertightly cover the peripheral surface of the nut member 21. A second sealing member 24 having a sheet-shaped second flange portion 26 which is provided at the lower end of the nut member 21 so as to spread around the nut member 21 and which can be watertightly adhered to the waterproof layer 2 is provided. Vulcanization adhesion is used as a means for watertightly providing the second sleeve portion 25 on the nut member 21.

このアンカー具２０を設置するには、設置部位Ｒに防水層２の一部を除去して下地１を露出させた箇所３を形成し、この箇所３に穿設した下穴４に例えば全ねじボルトから成る下側ボルト部材２７を上端側の一部を突出させて起立状態に埋設する。下側ボルト部材２７を埋設する手段としては、機械式、ケミカル式等、公知の手段が使用可能である。そして、下側ボルト部材２７に第１のねじ孔部２２を螺合させてナット部材２１を固定すると共に、第２のシール部材２４の第２のフランジ部２６を防水層２の表面に水密的に接着する。更に、ナット部材２１の第２のねじ孔部２３に例えば全ねじボルトから成る上側ボルト部材２８を螺合させる。 In order to install the anchor tool 20, a part 3 of the waterproof layer 2 is removed to form a portion 3 in which the base 1 is exposed in the installation portion R, and for example, a full screw is formed in the prepared hole 4 formed in this portion 3. The lower bolt member 27 made of bolts is embedded in an upright state with a part of the upper end side protruding. As a means for burying the lower bolt member 27, known means such as a mechanical type and a chemical type can be used. Then, the first screw hole portion 22 is screwed into the lower bolt member 27 to fix the nut member 21, and the second flange portion 26 of the second seal member 24 is watertightly attached to the surface of the waterproof layer 2. Adhere to. Further, the upper bolt member 28 made of, for example, all screw bolts is screwed into the second screw hole portion 23 of the nut member 21.

このように構成したアンカー具２０の設置構造によれば、ナット部材２１の第２のねじ孔部２３に螺合させた上側ボルト部材２８を利用することで、所定の構造物等を設置部位Ｒに取り付けることができる。ナット部材２１の周面と第２のシール部材２４の第２のスリーブ部２５との間が水密的に閉塞されると共に、第２のフランジ部２６と防水層２との間も水密的に閉塞される。又、第１のねじ孔部２２と第２のねじ孔部２３とは非連通なので、この部分での通水が阻止される。従って、設置部位Ｒにおける防水層２を除去した箇所３に、外部から水を到達させることがないから、下地１に水が浸入するのを確実に防止することができる。 According to the installation structure of the anchor tool 20 configured in this way, by using the upper bolt member 28 screwed into the second screw hole portion 23 of the nut member 21, a predetermined structure or the like can be installed at the installation site R. Can be attached to. The peripheral surface of the nut member 21 and the second sleeve portion 25 of the second sealing member 24 are watertightly closed, and the second flange portion 26 and the waterproof layer 2 are also watertightly closed. Will be done. Further, since the first screw hole portion 22 and the second screw hole portion 23 are not in communication with each other, water flow in this portion is blocked. Therefore, since water does not reach the portion 3 in the installation portion R from which the waterproof layer 2 has been removed from the outside, it is possible to reliably prevent water from entering the base 1.

アンカー具２０は、ナット部材２１を下側ボルト部材２７に螺合して固定する構造であるから、着脱が容易である。このため、アンカー具２０のメンテナンスや仕様変更を簡単に行える。アンカー具２０と防水層２とが力学的に独立する構造であり、下側ボルト部材２７の周囲に、防水層２に接着されない第２のフランジ部２６の領域が存在することにより、アンカー具２０に荷重が作用して変位が生じたとしても、防水層２に剥離力や剪断力が作用しにくくなる。このため、安定した防水性能を得ることが可能である。 Since the anchor tool 20 has a structure in which the nut member 21 is screwed and fixed to the lower bolt member 27, it is easy to attach and detach. Therefore, maintenance and specification changes of the anchor tool 20 can be easily performed. The anchor tool 20 and the waterproof layer 2 have a mechanically independent structure, and the anchor tool 20 has a region of a second flange portion 26 that is not adhered to the waterproof layer 2 around the lower bolt member 27. Even if a load acts on the waterproof layer 2 to cause displacement, it becomes difficult for a peeling force or a shearing force to act on the waterproof layer 2. Therefore, it is possible to obtain stable waterproof performance.

A chemical formula is used as a means for burying the anchor portion 32. Then, for example, the upper bolt member 37 made of all screw bolts is screwed into the upper surface screw hole portion 33 of the main body portion 31a.

このように構成したアンカー具３０の設置構造によれば、固定部材３１の上面ねじ孔部３３に螺合させた上側ボルト部材３７を利用することで、所定の構造物等を設置部位Ｒに取り付けることができる。本体部３１ａの周面と第３のシール部材３４の第３のスリーブ部３５との間が水密的に閉塞されると共に、第３のフランジ部３６と防水層２との間も水密的に閉塞されるので、設置部位Ｒにおける防水層２を除去した箇所３に、外部から水を到達させることがない。従って、下地２に水が浸入するのを確実に防止できる。又、アンカー具３０と防水層２とが力学的に独立する構造であり、本体部３１ａの周囲に、防水層２に接着されない第３のフランジ部３６の領域が存在することにより、アンカー具３０に荷重が作用して変位が生じたとしても、防水層２に剥離力や剪断力が作用しにくくなる。このため、安定した防水性能を得ることが可能である。 According to the installation structure of the anchor tool 30 configured in this way, a predetermined structure or the like is attached to the installation portion R by using the upper bolt member 37 screwed into the upper surface screw hole portion 33 of the fixing member 31. be able to. The peripheral surface of the main body 31a and the third sleeve portion 35 of the third sealing member 34 are watertightly closed, and the third flange portion 36 and the waterproof layer 2 are also watertightly closed. Therefore, water does not reach the portion 3 from which the waterproof layer 2 has been removed in the installation portion R from the outside.

That is, the fixing member 51 of this example has a columnar non-threaded portion 51a in which no screw is formed in the intermediate portion, a threaded portion 52 in which a male screw is formed on the upper surface portion thereof, and an anchor portion 53 on the lower surface portion. Have. The non-threaded portion 51a, the threaded portion 52, and the anchor portion 53 may be integrally formed or may be configured by assembling another member. The non-threaded portion 51a may have a columnar shape, a hexagonal columnar shape, or any other columnar shape.

第５のシール部材５４は、非ねじ部５１ａの周面を水密的に覆う第５のスリーブ部５５及び第５のスリーブ部５５の下端に非ねじ部５１ａの周囲に広がるように設けられ防水層２に水密的に接着可能なシート状の第５のフランジ部５６を有している。第５のスリーブ５５を固定部材５１の非ねじ部５１ａに水密的に設ける手段としては、加硫接着が用いられる。 The fifth sealing member 54 is provided at the lower ends of the fifth sleeve portion 55 and the fifth sleeve portion 55 that watertightly covers the peripheral surface of the non-threaded portion 51a so as to spread around the non-threaded portion 51a. It has a sheet-shaped fifth flange portion 56 that can be watertightly adhered to 2. Vulcanization adhesion is used as a means for watertightly providing the fifth sleeve 55 on the non-threaded portion 51a of the fixing member 51.

このアンカー具５０の施工手順は、第１の実施の形態と同様であるので、説明を省略する。 Since the construction procedure of the anchor tool 50 is the same as that of the first embodiment, the description thereof will be omitted.

本例のアンカー具５０及びその設置構造によれば、第１の実施の形態の作用・効果に加えて、非ねじ部５１ａの直径をねじ部５２の直径よりも大きく設定することにより、非ねじ部５１ａの上端面５１ｂを、構造物を設置するために使用する架台等の支持面として使用することができる。 According to the anchor tool 50 of this example and its installation structure, in addition to the operation / effect of the first embodiment, the diameter of the non-threaded portion 51a is set to be larger than the diameter of the threaded portion 52, whereby the non-threaded portion 51a is set to be larger than the diameter of the threaded portion 52.

［第７の実施の形態］
図９は本発明の第７の実施の形態に関するものであって、（Ａ）は設置部位とアンカー具とを分離して示す断面図であり、（Ｂ）はアンカー具を設置部位に設置した状況を示す断面図である。 [7th Embodiment]
9A and 9B relate to a seventh embodiment of the present invention, FIG. 9A is a cross-sectional view showing the installation site and the anchor tool separately, and FIG. 9B shows the anchor tool installed at the installation site. It is sectional drawing which shows the situation.

本例は、第１の実施の形態において、第１のシール部材１４の第１のフランジ部１６における中央部を湾曲させて、その下面中央部に凹部から成る樹脂ポケット１４ａを形成し、固定部材１１のアンカー部１３を下穴４にケミカル式で埋設する際に、下地１の表面に溢れ出た合成樹脂Ｑをこの樹脂ポケット１４ａに収納するように構成したものである。 In this example, in the first embodiment, the central portion of the first flange portion 16 of the first sealing member 14 is curved to form a resin pocket 14a formed of a recess in the central portion of the lower surface thereof, and the fixing member is formed. When the anchor portion 13 of 11 is embedded in the prepared hole 4 by a chemical method, the synthetic resin Q overflowing on the surface of the base 1 is configured to be stored in the resin pocket 14a.

ケミカル式アンカーでは、合成樹脂Ｑを下地１の表面に溢れ出させ、それによって下穴４とアンカー部１３との隙間が合成樹脂で確実に充填されていることを確認する。但し通常は、表面に溢れた合成樹脂の拭き取り作業を行う必要がある。しかし本例のように構成すれば、固定部材１１のアンカー部１３を下穴４内へ挿入したときに、下地１の表面に溢れ出た合成樹脂Ｑを、第１のシート部材１４の樹脂ポケット１４ａ内に収納させることができるから、溢れた合成樹脂Ｑを除去する必要がなくなるという利点が得られる。 In the chemical anchor, the synthetic resin Q overflows to the surface of the base 1, whereby it is confirmed that the gap between the prepared hole 4 and the anchor portion 13 is surely filled with the synthetic resin. However, usually, it is necessary to wipe off the synthetic resin overflowing on the surface. However, if it is configured as in this example, when the anchor portion 13 of the fixing member 11 is inserted into the prepared hole 4, the synthetic resin Q that overflows on the surface of the base 1 is put into the resin pocket of the first sheet member 14. Since it can be stored in 14a, there is an advantage that it is not necessary to remove the overflowing synthetic resin Q.

[その他の実施の形態]
本発明のアンカー具が設置される設置部位は、建築物の屋上の外、屋根、バルコニー、厨房等の防水床、防水壁、道路等、下地の表面に防水層を有するものが対象となる。防水層は一般に塗膜や防水シートで形成されるが、これらに限定されない。 [Other embodiments]
