特開２００５−２２０６５８号公報（図４、図７）Japanese Patent Laying-Open No. 2005-220658 (FIGS. 4 and 7)

上述した従来の他物固定具によれば、固定本体が硬質合成樹脂で構成してあるから、大きな荷重が他物から作用する場合には、強度的な問題点があり、その問題を解消するのに、固定具の数を増やして、荷重分散を図る必要があった。
その結果、他物固定具の設置数が多くなり、設置コストが高くついていた。 According to the conventional other fixture described above, since the fixing main body is made of a hard synthetic resin, there is a problem in strength when a large load acts from another, and the problem is solved. However, it was necessary to increase the number of fixtures to achieve load distribution.
As a result, the number of other fixtures installed increased and the installation cost was high.

従って、本発明の目的は、上記問題点を解消し、他物に対する固定強度を高く確保でき、設置数を減少させることができる他物固定具を提供するところにある。 Accordingly, an object of the present invention is to provide a fixture for other objects that can solve the above-mentioned problems, can secure a high fixing strength for other objects, and can reduce the number of installations.

本発明の第１の特徴構成は、下地上に防水シートを敷設して構成してある設置対象部の上方に他物を取付自在な他物固定具であって、前記設置対象部に接地自在な接地底部を備え、金属によって一体に構成してあると共に全体が合成樹脂によって鋳ぐるまれた固定本体と、ボルトによって構成され、前記固定本体に形成された挿通孔に挿通された状態で、基端部側が前記固定本体に埋設保持されると共に先端部側が前記固定本体の鋳ぐるみ層を貫通して前記接地底部とは反対側に突出された他物固定部と、を備えてあるところにある。
本発明の第２の特徴構成は、前記固定本体のうち前記接地底部の側に、接地状態において前記設置対象部側に開口する凹入部が形成され、前記凹入部の内周面は、前記鋳ぐるみ層によって鋳ぐるまれているところにある。
本発明の第３の特徴構成は、下地上に防水シートを敷設して構成してある設置対象部に対して接地自在な接地底部と、前記設置対象部の上方に設置する他物を取付固定自在な他物固定部とを、固定本体に備えてある他物固定具であって、前記固定本体は金属によって構成してあり、前記固定本体は、合成樹脂によって鋳ぐるんであり、前記他物固定部は、前記固定本体から鋳ぐるみ層を貫通して突出する状態に設けられたボルトで構成してあり、前記ボルトには、突出部分における基端部とその周囲の鋳ぐるみ層との間をシールするシーリングワッシャが外嵌させて設けてあるところにある。 A first characteristic configuration of the present invention is an other-object fixture that allows other objects to be mounted above an installation target portion that is configured by laying a waterproof sheet on a base, and can be grounded to the installation target portion. A fixed body that is integrally formed of metal and is cast entirely of a synthetic resin, and a bolt that is inserted through an insertion hole formed in the fixed body. An end portion side is embedded and held in the fixed body, and a tip portion side is provided with another object fixing portion that penetrates the cast layer of the fixed body and protrudes on the opposite side to the grounding bottom portion. .
According to a second characteristic configuration of the present invention, a recessed portion that opens to the installation target portion side in the grounded state is formed on the grounded bottom portion side of the fixed body, and an inner peripheral surface of the recessed portion is formed by the casting. It is in the place where it is cast by the round layer.
The third characteristic configuration of the present invention is that a grounding bottom portion that can be grounded to an installation target portion that is configured by laying a waterproof sheet on a base, and other objects that are installed above the installation target portion are fixedly attached. a freely other object securing part, be other material fixture are provided on the fixed body, the fixed body Yes constituted by metal, the fixed body, Ri Guru Ndea cast synthetic resin, the other The object fixing portion is constituted by a bolt provided so as to protrude from the fixed main body through the cast-in layer, and the bolt includes a base end portion in the protruding portion and a cast-in layer around it. during sealing washer is fitted to seal the in Oh Rutokoro be provided.

本発明の第３の特徴構成によれば、前記固定本体は金属によって構成してあり、固定本体の強度が従来品に比べて高まり、それに伴って、他物固定具としての固定強度を向上させることができる。その結果、従来と同様の他物を下地上に固定するのに、他物固定具一個所での固定強度が上がるから、全体としての他物固定具の設置数を少なくでき、設置手間の軽減を図ることができる。
更には、前記固定本体は、合成樹脂によって鋳ぐるんであるから、金属が外部に露出するのを前記合成樹脂の鋳ぐるみ部で防止できる。その結果、金属部分の酸化による腐食の進行を防止して、耐久性の向上を図ることができるから、長期間にわたって他物を安定した状態で下地上に固定しておくことができる。 According to the third characteristic configuration of the present invention, the fixed main body is made of metal, and the strength of the fixed main body is higher than that of the conventional product, and accordingly, the fixing strength as a fixture for other objects is improved. be able to. As a result, when fixing other objects as before, the fixing strength at one place for fixing other objects is increased, so the number of other objects can be reduced as a whole, and the installation effort is reduced. Can be achieved.
Furthermore, since the fixed main body is cast with synthetic resin, the synthetic resin can prevent the metal from being exposed to the outside. As a result, the progress of corrosion due to oxidation of the metal portion can be prevented and the durability can be improved, so that other objects can be stably fixed on the base for a long period of time.

また、合成樹脂による鋳ぐるみ層の内方側に水が浸入するのを前記シーリングワッシャによって防止することができる。
即ち、前記ボルトが、固定本体から鋳ぐるみ層を貫通して突出しているから、シーリングワッシャが無ければ、ボルトの突出部に沿って水が鋳ぐるみ層内に浸入し易く、もし、鋳ぐるみ層内に水が浸入したら、金属製の固定本体や、ボルトの埋設部分を腐食させる危険性がある。金属部の腐食に関しては、水による酸化の影響の他に、固定本体とボルトとが異なる金属で構成されている場合、水に浸されることで相互の電位差に基因した腐食（所謂「電食」）を生じる危険性がある。
従って、前記ボルトの突出部分における基端部とその周囲の鋳ぐるみ層との間を、ボルトに外嵌させたシーリングワッシャによってシールすることで、鋳ぐるみ層内への水の浸入を防止でき、金属そのものの高強度を維持することができる。
その結果、鋳ぐるみ層内部での金属部分の腐食を防止して、耐久性の向上を図ることができるから、長期間にわたって他物を安定した状態で下地上に固定しておくことができる。 In addition, the sealing washer can prevent water from entering the inner side of the cast-in layer made of synthetic resin.
That is, since the bolt protrudes from the fixed main body through the cast-out layer, if there is no sealing washer, water can easily enter the cast-out layer along the projecting portion of the bolt. If water enters the inside, there is a risk of corroding the metal fixing body and the embedded part of the bolt. Regarding the corrosion of metal parts, in addition to the effects of oxidation by water, when the fixed main body and the bolt are made of different metals, corrosion caused by the mutual potential difference by soaking in water (so-called “electric corrosion” )).
Therefore, sealing between the base end portion of the projecting portion of the bolt and the surrounding cast-out layer with a sealing washer fitted on the bolt can prevent water from entering the cast-up layer, The high strength of the metal itself can be maintained.
As a result, corrosion of the metal portion inside the cast-in layer can be prevented and durability can be improved, so that other objects can be stably fixed on the base for a long period of time.

本発明の第４の特徴構成は、前記固定本体に、一方が前記接地底部に開口すると共に、設置状態で他方が上方に開口するネジ部材挿通孔が設けてあり、前記ネジ部材挿通孔に挿通させるネジ部材の拡径頭部を受ける座繰り部が、前記ネジ部材挿通孔に形成してあり、前記座繰り部の座繰り面は、前記固定本体の金属が露出させてあるところにある。 According to a fourth characteristic configuration of the present invention, the fixed main body is provided with a screw member insertion hole, one of which opens in the grounding bottom portion and the other of which opens upward in the installed state, and is inserted into the screw member insertion hole. A countersink portion that receives the enlarged head of the screw member to be formed is formed in the screw member insertion hole, and a countersink surface of the countersink portion is where the metal of the fixed body is exposed.

本発明の第４の特徴構成によれば、ネジ部材挿通孔が設けてあり、前記ネジ部材挿通孔に挿通させるネジ部材の拡径頭部を受ける座繰り部が、前記ネジ部材挿通孔に形成してあるから、ネジ部材挿通孔に挿通させたネジ部材を下地に締着させることによって拡径頭部から座繰り面に押圧力が伝達されて当該他物固定具を下地に固定することができる。
また、固定本体は、合成樹脂で鋳ぐるんであるにも拘わらず、前記座繰り部の座繰り面は、前記固定本体の金属が露出させてあるから、固定本体の座繰り面とネジ部材の拡径頭部とは金属どうしが直接的に接触する状態で押圧力の伝達が図られ、ネジ部材の締め付けトルク管理を行う上で、バラツキを押さえた精度の高い締め付け管理を行うことができる。
比較例として、座繰り面に合成樹脂の鋳ぐるみ層が存在している場合を例に挙げると、鋳ぐるみ層が金属間に介在して弾性変形することで、ネジ部材の締め付けトルクにバラツキを生じ易くなり、所定の締着力で固定することが困難となる。更には、鋳ぐるみ層のクリープ変形によってネジ部材の緩みを誘発し、他物固定具の取付状況に悪影響を与える危険性がある。本発明の特徴構成によれば、このような問題点を解消し、緩み難い状態に他物固定具を下地に固定することができる。 According to the fourth characteristic configuration of the present invention, the screw member insertion hole is provided, and the counterbore portion for receiving the enlarged head portion of the screw member inserted through the screw member insertion hole is formed in the screw member insertion hole. Therefore, by pressing the screw member inserted through the screw member insertion hole to the base, the pressing force is transmitted from the enlarged diameter head to the countersink surface, and the other object fixing tool can be fixed to the base. it can.
In addition, although the fixed body is casted with a synthetic resin, the metal of the fixed body is exposed on the countersink surface of the countersunk portion. A pressing force is transmitted in a state in which the metals are in direct contact with the enlarged diameter head, and when performing tightening torque management of the screw member, it is possible to perform highly accurate tightening management with suppressed variation.
As a comparative example, in the case where a synthetic resin cast-out layer exists on the countersink surface, for example, the cast-out layer is interposed between the metals and elastically deformed, thereby varying the tightening torque of the screw member. It tends to occur, and it becomes difficult to fix with a predetermined fastening force. Furthermore, there is a risk that the screw member may be loosened due to creep deformation of the cast layer and adversely affect the mounting state of the other fixture. According to the characteristic configuration of the present invention, such a problem can be solved, and the other object fixing tool can be fixed to the ground in a state in which it is difficult to loosen.

本発明の第５の特徴構成は、前記ネジ部材挿通孔に挿通自在な固定用ネジ部材を備え、

In the state where the fixing screw member is inserted through the screw member insertion hole and the fixing main body is fixed to the base, the upper surface of the enlarged diameter head portion of the screw member is lower than the upper edge portion of the countersink portion. It is where it is formed.

本発明の第５の特徴構成によれば、ネジ部材を設置した状態で、その拡径頭部の上方に、座繰り部の上縁部より入り込んだ凹部を形成することができ、この凹部に、例えば、ネジ部材周りをシールするシール材を充填することが可能となる。ネジ部材挿通孔をシール材でシールできれば、ネジ部材挿通孔内への水の浸入を防止できるから、ネジ部材による防水シートの貫通部に水が浸入したり、下方へ漏水することを防止できる。
即ち、他物固定具の取付部分の防水性の維持を図ることができる。 According to the fifth characteristic configuration of the present invention, in a state where the screw member is installed, a concave portion that enters from the upper edge portion of the countersink portion can be formed above the enlarged diameter head portion. For example, it is possible to fill a sealing material that seals around the screw member. If the screw member insertion hole can be sealed with a sealing material, it is possible to prevent water from entering the screw member insertion hole, so that it is possible to prevent water from entering the leaking portion of the waterproof sheet by the screw member or leaking downward.
That is, it is possible to maintain the waterproofness of the attachment part of the other object fixture.

本発明の第６の特徴構成は、前記ネジ部材挿通孔の開口部を開閉自在な蓋部材が設けてあり、前記ネジ部材挿通孔に前記蓋部材を取り付けた状態で、前記ネジ部材挿通孔に外部からの水が浸入するのを阻止すると共に、前記ネジ部材挿通孔と外部空間とを連通させる連通機構が設けてあるところにある。 According to a sixth characteristic configuration of the present invention, there is provided a lid member that can freely open and close the opening of the screw member insertion hole, and the screw member insertion hole has the lid member attached to the screw member insertion hole. There is provided a communication mechanism that prevents water from entering from the outside and communicates the screw member insertion hole with the external space.

本発明の第６の特徴構成によれば、蓋部材をネジ部材挿通孔の開口部に取り付けることによって、ネジ部材挿通孔内への水の浸入を防止できるから、ネジ部材による防水シートの貫通部に水が浸入したり、下方へ漏水することを防止できる。
即ち、他物固定具の取付部分の防水性の維持を図ることができる。
更には、前記ネジ部材挿通孔に前記蓋部材を取り付けた状態で、前記ネジ部材挿通孔に外部からの水が浸入するのを阻止すると共に、前記ネジ部材挿通孔と外部空間とを連通させる連通機構が設けてあるから、例えば、他物固定具の周囲環境の温度上昇によって、ネジ部材挿通孔内の空気が熱膨張したとしても、連通機構を通して内部の圧抜きを行うことができる。従って、熱膨張によって前記蓋部材が跳ね上げられて外れることを防止できる。その結果、環境温度の変化がある設置対象部であっても、他物固定具の取付部分の防水性の維持を図ることができる。 According to the sixth characteristic configuration of the present invention, since the intrusion of water into the screw member insertion hole can be prevented by attaching the lid member to the opening of the screw member insertion hole, the penetration portion of the waterproof sheet by the screw member It is possible to prevent water from entering or leaking downward.
That is, it is possible to maintain the waterproofness of the attachment part of the other object fixture.
Furthermore, in the state which attached the said lid member to the said screw member insertion hole, while preventing that the water from the outside penetrate | invades into the said screw member insertion hole, it is the communication which connects the said screw member insertion hole and external space Since the mechanism is provided, for example, even if the air in the screw member insertion hole is thermally expanded due to a temperature rise in the surrounding environment of the other fixture, the internal pressure can be released through the communication mechanism. Therefore, it is possible to prevent the lid member from being flipped up and removed due to thermal expansion. As a result, it is possible to maintain the waterproofness of the attachment part of the other object fixture even in the installation target part where the environmental temperature changes.

Incidentally, the adhesion of the waterproof sheet 5 to the base 3 is performed by, for example, attaching a metal plate for fixing the waterproof sheet (not shown in the figure, for example, a disk-like or strip-like one) with screws, concrete nails, bolts, etc. Examples include a method in which the waterproof sheet 5 is adhered to the upper surface of the metal plate by applying an adhesive to the upper surface of the metal plate, and the waterproof sheet 5 is adhered to the entire surface.
In the present embodiment, the waterproof sheet 5 is described by taking vinyl chloride as an example.

前記固定具Ｋは、図２、図３に示すように、屋上スラブ１に対して接着自在な円板形状の底面部（接地底部に相当）６Ａと、その底面部６Ａの中央上方にボルト（他物固定部に相当）７を埋設保持した状態に立設してある平面視十文字形状の立設部６Ｂとを一体に備えた金属製の固定本体６によって構成してある。尚、前記固定本体６は、合成樹脂（例えば、塩化ビニル）によって外周部（上下面及び側面）に鋳ぐるみ層１０（図３〜５参照）を設けてある。 As shown in FIGS. 2 and 3, the fixture K includes a disc-shaped bottom surface portion (corresponding to a grounding bottom portion) 6A that can be bonded to the roof slab 1 and a bolt ( It corresponds to the other object fixing part) and is constituted by a metal fixing main body 6 integrally provided with a standing part 6B having a cross-sectional shape in plan view that is erected in a state where 7 is embedded and held. The fixed body 6 is provided with a cast layer 10 (see FIGS. 3 to 5) on the outer peripheral portion (upper and lower surfaces and side surfaces) of synthetic resin (for example, vinyl chloride).

前記立設部６Ｂの平面視十文字は、二つの一文字が平面視で直交する状態に形成されており、一つの一文字の両端部には、縦方向に貫通するネジ部材挿通孔８がそれぞれ形成されている。
このネジ部材挿通孔８の内周面の内、前記固定本体６の金属部分はそのまま金属が露出する状態に形成されている。
また、ネジ部材挿通孔８の金属部分には、挿通させる固定用ネジ部材９（図５参照）の拡径頭部９ａを受ける座繰り部８ａが形成してあり、ネジ部材挿通孔８内に、上方から固定用ネジ部材９を挿通させて下方の下地３に締め込むに伴って、前記拡径頭部９ａが座繰り部８ａに直接に接触して下地側に挟圧して、固定具Ｋを下地３に固定することができる。
また、ネジ部材挿通孔８の金属部分の上方には、鋳ぐるみ樹脂で構成された筒状部１０ａが立ち上げられている。
また、前記筒状部１０ａの上端部から、前記座繰り部８ａまでの深さ寸法の設定は、図５に示すように、前記固定用ネジ部材９を前記ネジ部材挿通孔８に挿通して前記固定本体６を前記下地３に固定した状態で、固定用ネジ部材９の拡径頭部９ａの上面が、前記筒状部１０ａの上縁部より低くなるように設定してある。
前記固定用ネジ部材９の上方に確保される凹部８ｂは、シール材１１の充填空間として使用される。ネジ部材挿通孔８に固定用ネジ部材９を挿通させて下地３に固定した後、前記凹部８ｂにシール材１１を充填することで、ネジ部材挿通孔８内から固定用ネジ部材９に沿って下地２側へ漏水するのを防止できる。 In the plan view of the upright portion 6B, two letters are formed in a state where two letters are orthogonal to each other in plan view, and screw member insertion holes 8 penetrating in the vertical direction are formed at both ends of the letter. ing.
Of the inner peripheral surface of the screw member insertion hole 8, the metal portion of the fixed body 6 is formed so that the metal is exposed as it is.
Further, the metal portion of the screw member insertion hole 8 is formed with a countersink portion 8a that receives the enlarged diameter head portion 9a of the fixing screw member 9 (see FIG. 5) to be inserted. As the fixing screw member 9 is inserted from the upper side and tightened to the lower base 3, the enlarged diameter head 9 a directly contacts the countersink portion 8 a and is clamped to the base side to fix the fixing tool K. Can be fixed to the base 3.
Further, a cylindrical portion 10 a made of cast-in resin is raised above the metal portion of the screw member insertion hole 8.
Further, the depth dimension from the upper end portion of the cylindrical portion 10a to the countersink portion 8a is set by inserting the fixing screw member 9 into the screw member insertion hole 8 as shown in FIG. In a state where the fixing main body 6 is fixed to the base 3, the upper surface of the enlarged diameter head portion 9a of the fixing screw member 9 is set to be lower than the upper edge portion of the cylindrical portion 10a.
The concave portion 8 b secured above the fixing screw member 9 is used as a filling space for the sealing material 11. After the fixing screw member 9 is inserted into the screw member insertion hole 8 and fixed to the base 3, the concave portion 8 b is filled with the sealing material 11, so that the screw member insertion hole 8 extends along the fixing screw member 9. It is possible to prevent water leakage to the base 2 side.

前記筒状部１０ａには、前記ネジ部材挿通孔８の開口部を開閉自在な蓋部材１２が設けてある。
蓋部材１２は、前記鋳ぐるみ層１０と同じ合成樹脂材料で構成してあり、図３に示すように、前記筒状部１０ａの外径より大きい直径寸法の天板部１２ａと、天板部１２ａの外周縁部から下方に垂下する外筒部１２ｂと、天板部１２ａにおける前記外筒部１２ｂより内側の位置に垂下する内筒部１２ｃとを設けて構成してある。
前記内筒部１２ｃは、周方向に４分割の分割筒部１３によって構成してあり、周方向に隣合う分割筒部１３には、それぞれ縦スリットＳ１が形成されている。また、各分割筒部１３の外周面における周方向での中央部分には、縦方向の凸条部１３ａが形成されている。 The cylindrical portion 10a is provided with a lid member 12 that can open and close the opening of the screw member insertion hole 8.
The lid member 12 is made of the same synthetic resin material as the cast-in layer 10, and as shown in FIG. 3, a top plate portion 12a having a diameter larger than the outer diameter of the cylindrical portion 10a, and a top plate portion The outer cylinder part 12b which hangs down from the outer peripheral edge part of 12a and the inner cylinder part 12c which hangs down to the position inside the said outer cylinder part 12b in the top-plate part 12a are provided.
The inner cylinder part 12c is constituted by a divided cylinder part 13 divided into four in the circumferential direction, and a vertical slit S1 is formed in each of the divided cylinder parts 13 adjacent in the circumferential direction. In addition, a vertical ridge 13a is formed at a central portion in the circumferential direction on the outer peripheral surface of each divided cylindrical portion 13.

前記内筒部１２ｃの寸法設定は、各凸条部１３ａに外接する円の直径が、前記筒状部１０ａの内径寸法より若干大きくなるように設定してある。また、長さに関しては、固定本体６に蓋部材１２を取り付けた状態で、内筒部１２ｃの下端部が、ネジ部材挿通孔８内の金属部分に当接する程度に設定してある。 The dimension of the inner cylinder part 12c is set so that the diameter of a circle circumscribing each protruding line part 13a is slightly larger than the inner diameter dimension of the cylindrical part 10a. Further, the length is set such that the lower end portion of the inner cylinder portion 12 c is in contact with the metal portion in the screw member insertion hole 8 with the lid member 12 attached to the fixed body 6.

蓋部材１２をネジ部材挿通孔８に取り付けるには、内筒部１２ｃを筒状部１０ａに内嵌させて押し込むことで実施される。その際、各分割筒部１３は、ネジ部材挿通孔８の内周壁から凸条部１３ａが縮径側に押圧され、前記縦スリットＳ１の幅が縮まる方向に撓み変形するから、各分割筒部１３の弾性復元力が、前記凸条部１３ａを介してネジ部材挿通孔８の内周面に集中的に作用し、互いの嵌合力の向上が図られる。よって、外れ難い状態に蓋部材１２を固定本体６に取り付けることができる。 The lid member 12 is attached to the screw member insertion hole 8 by inserting the inner cylindrical portion 12c into the cylindrical portion 10a and pushing it. At that time, each divided cylinder part 13 is bent and deformed in a direction in which the protruding portion 13a is pressed to the reduced diameter side from the inner peripheral wall of the screw member insertion hole 8 and the width of the vertical slit S1 is reduced. The elastic restoring force 13 acts intensively on the inner peripheral surface of the screw member insertion hole 8 through the convex portion 13a, and the mutual fitting force is improved. Therefore, the lid member 12 can be attached to the fixed main body 6 so as not to be detached.
