Description

本発明は、防水下地の上に沿って設けられる防水シートを防水下地に固定する防水シート固定具に関する。 The present invention relates to a waterproof sheet fixture that fixes a waterproof sheet provided along the waterproof base to the waterproof base.

従来、この種の防水シート固定具としては、例えば、金属製の円板からなる固定具本体の上面に、防水シートを接着固定自在な固定部（ホットメルト接着層）を備えるとともに、固定具本体の中央部にネジ挿通孔が形成されており、このネジ挿通孔に挿通させたネジ部材で防水下地に固定するように構成されたものがあった（例えば、特許文献１参照）。 Conventionally, as this type of waterproof sheet fixture, for example, a fixing portion (hot melt adhesive layer) capable of adhering and fixing the waterproof sheet is provided on the upper surface of the fixture main body made of a metal disk, and the fixture main body. A screw insertion hole was formed in the central portion of the screw insertion hole, and there was a screw member inserted through the screw insertion hole so as to be fixed to a waterproof base (see, for example, Patent Document 1).

防水シート固定具への防水シートの固定に関しては、例えば、防水下地に設置した防水シート固定具の上から防水シートを被せ、その上方から、電磁誘導加熱装置を用いて固定具本体を加熱することで上述の固定部上の接着層を溶かし、防水シートを固定具本体に固定する構成となっている。 Regarding the fixing of the waterproof sheet to the waterproof sheet fixture, for example, cover the waterproof sheet fixture installed on the waterproof base with the waterproof sheet, and heat the fixture body from above using an electromagnetic induction heating device. The structure is such that the adhesive layer on the above-mentioned fixing portion is melted and the waterproof sheet is fixed to the fixture body.

そして、上述のように設置された防水シートを改修する場合には、例えば、既に設置されている防水シート固定具の平面位置から側方にずれた箇所において、防水シートの上から改修用の新しい防水シート固定具を設置し、その防水シート固定具の上から改修用の防水シートを接着することで実施する方法（以下、第１の方法という）がある。
しかし、この改修方法によれば、改修用の防水シート固定具を設置する際に、防水下地にネジ部材を設置する必要があり、その作業に伴う騒音や振動が防水下地に伝播し、環境上好ましくないという問題点がある。 Then, when repairing the waterproof sheet installed as described above, for example, at a position shifted laterally from the flat position of the already installed waterproof sheet fixture, a new one for repair is used from above the waterproof sheet. There is a method (hereinafter referred to as the first method) in which a waterproof sheet fixing tool is installed and a waterproof sheet for repair is adhered on the waterproof sheet fixing tool.
However, according to this repair method, when installing the waterproof sheet fixture for repair, it is necessary to install a screw member on the waterproof base, and the noise and vibration associated with the work propagate to the waterproof base, which is environmentally friendly. There is a problem that it is not preferable.

この騒音振動問題を緩和する改修方法として、次のような方法があった。すなわち、既に設置されている防水シート固定具の周囲に沿って防水シートに切り込みを入れると共に、防水シート固定具を再加熱して固定部の接着層を溶かし、切り込みを入れた防水シート部分を、防水シート固定具上から除去したのち、切取り部分に露出した防水シート固定具はそのまま使用して、その上に新たな接着層を設けて、それらの上から改修用の防水シートを敷設して防水シート固定具に接着する方法（以下、第２の方法という）である（例えば、特許文献１参照）。 The following methods have been used as repair methods to alleviate this noise and vibration problem. That is, a notch is made in the waterproof sheet along the periphery of the already installed waterproof sheet fixture, and the waterproof sheet fixture is reheated to melt the adhesive layer of the fixing portion, and the notched waterproof sheet portion is formed. After removing from the waterproof sheet fixture, the waterproof sheet fixture exposed in the cutout part is used as it is, a new adhesive layer is provided on it, and a waterproof sheet for repair is laid on them to make it waterproof. This is a method of adhering to a sheet fixture (hereinafter referred to as a second method) (see, for example, Patent Document 1).

特開２００２−８８９８６号公報Japanese Unexamined Patent Publication No. 2002-88886

上述した従来の防水シート固定具を用いる場合には、前記第１の方法による防水シートの改修を行えば、上述したようにネジ部材の設置に伴って騒音振動が発生するから、環境上好ましくない問題がある。また、前記第２の方法による防水シートの改修を行えば、防水シート固定具の固定部から、古い接着層を確実に除去するのに非常に手間が掛かり、防水シート改修の作業効率が低下する問題点がある。そして、古い接着層の除去作業を怠ると、その上から新しい接着層を被せても接着性能を十分に発揮できないおそれがある。 When the above-mentioned conventional waterproof sheet fixture is used, if the waterproof sheet is repaired by the first method, noise and vibration are generated with the installation of the screw member as described above, which is not preferable in terms of the environment. There's a problem. Further, if the waterproof sheet is repaired by the second method, it takes a lot of time and effort to reliably remove the old adhesive layer from the fixed portion of the waterproof sheet fixture, and the work efficiency of the waterproof sheet repair is lowered. There is a problem. If the work of removing the old adhesive layer is neglected, the adhesive performance may not be sufficiently exhibited even if a new adhesive layer is put on the old adhesive layer.

尚、前記第２の方法において、新しい接着層を被せるのに替えて、ネジ部材を外して防水シート固定具ごと新しいものに交換することも考えられるが、この方法では、プラグアンカー等に螺合させてあるネジ部材を一度外すと、プラグアンカーが緩み、再度、ネジ部材を螺着させても充分な固定力が得られなくなる虞があり、好ましくない。 In the second method, instead of covering with a new adhesive layer, it is conceivable to remove the screw member and replace the waterproof sheet fixture with a new one, but in this method, it is screwed into a plug anchor or the like. Once the screw member is removed, the plug anchor may loosen, and even if the screw member is screwed in again, a sufficient fixing force may not be obtained, which is not preferable.

本発明の目的は、上記問題点を解消し、騒音や振動の発生を抑えながら、効率よく防水シート改修作業を実施することが可能となる防水シート固定具を提供する点にある。 An object of the present invention is to provide a waterproof sheet fixture capable of efficiently performing a waterproof sheet repair work while solving the above-mentioned problems and suppressing the generation of noise and vibration.

本発明に係る防水シート固定具の特徴構成は、
防水下地の上に敷設された防水シートを、前記防水下地に固定する防水シート固定具であって、
第一シート固定部を有するとともに、釘またはビスによって前記防水下地に固定可能な第一部材と、
第二シート固定部を有するとともに、前記第一部材の上方に配置された状態で前記第一部材に連結されることで前記防水下地に固定可能な第二部材と、
前記第一部材と前記第二部材とを連結する連結部と、が備えられ、
前記第一部材に、前記釘または前記ビスが挿通可能な第一開口部が形成され、
前記第二部材のうち、前記第一開口部に対応する位置に、第二開口部が形成され、
前記連結部は、前記第一開口部と前記第二開口部とに亘る状態で設けられて、前記第一部材と前記第二部材とを連結する点にある。 The characteristic configuration of the waterproof sheet fixture according to the present invention is
A tarpaulin fixture that fixes a tarpaulin laid on a waterproof base to the waterproof base.
A first member that has a first sheet fixing part and can be fixed to the waterproof base with nails or screws.
A second member that has a second sheet fixing portion and can be fixed to the waterproof base by being connected to the first member in a state of being arranged above the first member.
A connecting portion for connecting the first member and the second member is provided.
A first opening through which the nail or the screw can be inserted is formed in the first member.
A second opening is formed at a position corresponding to the first opening in the second member.
The connecting portion is provided so as to extend over the first opening and the second opening, and is at a point where the first member and the second member are connected.

本発明によれば、第一部材が釘またはビスによって防水下地に固定され、第一部材の第一シート固定部によって防水シートが固定される。そして、年数の経過に伴って新しい防水シートに改修するにあたっては、古い防水シートのうち少なくとも第一部材の第一開口部に対応する箇所を切り取り、その第一開口部に対応させて第二開口部を位置させた状態で第二部材を上方側から載置して、第一開口部と第二開口部とに亘る状態で設けられた連結部によって、第一部材と第二部材とを連結する。そして、第二部材の上面に新しい防水シートを接着して固定することができる。 According to the present invention, the first member is fixed to the waterproof base by nails or screws, and the waterproof sheet is fixed by the first sheet fixing portion of the first member. Then, when repairing to a new waterproof sheet over the years, at least the part of the old waterproof sheet corresponding to the first opening of the first member is cut out, and the second opening corresponds to the first opening. The second member is placed from above with the portion positioned, and the first member and the second member are connected by a connecting portion provided over the first opening and the second opening. do. Then, a new waterproof sheet can be adhered and fixed to the upper surface of the second member.

すなわち、古い防水シートを固定するための第一部材を防水下地に固定した状態のまま、再使用することができるので、第一部材を取り外す手間がなく、しかも、この第一部材を有効利用して、第二部材を取り付けるので、防水下地に新たな取付け用の孔を穿設する必要がない。その結果、新たな取付け用の孔を穿設する作業に伴う騒音や振動等の発生を回避できる。 That is, since the first member for fixing the old waterproof sheet can be reused while being fixed to the waterproof base, there is no need to remove the first member, and the first member can be effectively used. Since the second member is attached, it is not necessary to make a new attachment hole in the waterproof base. As a result, it is possible to avoid the generation of noise, vibration, etc. associated with the work of drilling a new mounting hole.

連結部は、釘またはビスが挿通可能な第一開口部の構成を利用して、第一部材と第二部材とを連結するものである。この構成に代えて、例えば、第一部材と第二部材とを連結する構成として、第一開口部から径方向に離れた箇所に、周方向に沿って分散配置された複数箇所にてビス等により連結する構成が考えられるが、このような構成では、連結箇所が多くなって設置作業が煩わしいものとなるおそれがある。これに対して、上記連結部は、第一開口部の構成を利用して、第一部材と第二部材とを連結する構成とすることで、簡単な連結構造によって両者を固定することができる。 The connecting portion connects the first member and the second member by utilizing the structure of the first opening through which a nail or a screw can be inserted. Instead of this configuration, for example, as a configuration in which the first member and the second member are connected, screws or the like are arranged at a plurality of locations dispersed along the circumferential direction at locations separated in the radial direction from the first opening. However, in such a configuration, the number of connecting points may increase and the installation work may become troublesome. On the other hand, the connecting portion can be fixed by a simple connecting structure by connecting the first member and the second member by utilizing the configuration of the first opening. ..

従って、騒音や振動の発生を抑えながら、簡単な連結構造によって、効率よく防水シート改修作業を実施することが可能な防水シート固定具を提供できるに至った。 Therefore, it has become possible to provide a waterproof sheet fixture capable of efficiently performing a waterproof sheet repair work by a simple connecting structure while suppressing the generation of noise and vibration.

図１に示すように、防水シート固定具１（以下、単にシート固定具という）は、屋根下地（防水下地の一例）２の上に防水シート３を固定するものである。 As shown in FIG. 1, the waterproof sheet fixing tool 1 (hereinafter, simply referred to as a sheet fixing tool) fixes the waterproof sheet 3 on the roof base (an example of the waterproof base) 2.

屋根下地２は、この実施形態においては、鉄筋コンクリート製のスラブによって構成されている。そして、屋根下地２には断熱材４が敷設され、断熱材４の上側に配置された状態で防水シート３が備えられている。屋根下地２は、鉄筋コンクリート構造のスラブの他、例えば、ＡＬＣ板を敷き並べて形成したスラブや、デッキプレートや金属折板とコンクリートを組み合わせて形成したスラブや、それらスラブの上に断熱層を積層させたもの等を用いることもできる。そして、屋根下地２は、シート固定具１を固定するためのビスを抜け止め状態に支持することができるものであることが好ましい。 In this embodiment, the roof base 2 is composed of a slab made of reinforced concrete. A heat insulating material 4 is laid on the roof base 2, and a waterproof sheet 3 is provided in a state of being arranged above the heat insulating material 4. The roof base 2 is a slab having a reinforced concrete structure, for example, a slab formed by laying ALC plates side by side, a slab formed by combining a deck plate or a metal folded plate and concrete, and a heat insulating layer laminated on these slabs. It is also possible to use a slab or the like. Then, it is preferable that the roof base 2 can support the screw for fixing the seat fixture 1 in a retaining state.

断熱材４は、断熱素材からなる板状の部材である。断熱材４の材質としては、例えば、ポリスチレン、ウレタン、イソシアネート等の種々のものを採用できる。また、図１に示す防水シート３は、可撓性を有し、例えば、塩化ビニル等の合成樹脂で構成されている。 The heat insulating material 4 is a plate-shaped member made of a heat insulating material. As the material of the heat insulating material 4, for example, various materials such as polystyrene, urethane, and isocyanate can be adopted. Further, the waterproof sheet 3 shown in FIG. 1 has flexibility and is made of, for example, a synthetic resin such as vinyl chloride.

図示しないが、シート固定具１は、屋根下地２に対して間隔を空けて複数配置され、防水シート３は、複数の防水シート固定具１を用いて屋根下地２に固定されるようになっている。 Although not shown, a plurality of sheet fixtures 1 are arranged at intervals with respect to the roof base 2, and the waterproof sheet 3 is fixed to the roof base 2 by using the plurality of waterproof sheet fixtures 1.

図１，２に示すように、シート固定具１には、板状の上面部としての円板状の板状部材５と、板状部材５に挿通自在でビス６によって屋根下地２に固定される筒状部としての取付部材７とが備えられている。板状部材５は、金属板をプレス加工によって成形してあり、円板の中央部分に、取付部材７を挿通自在な第一開口部としての挿通孔８が形成されている。その挿通孔８の外周側の部分が上方に膨出しており、その上面部分に、防水シート３が固定される第一シート固定部としての接着部９が設けられている。従って、板状部材５と取付部材７とにより、ビス６によって屋根下地２に固定可能な第一部材Ｄ１が構成されている。 As shown in FIGS. 1 and 2, the sheet fixture 1 has a disk-shaped plate-shaped member 5 as a plate-shaped upper surface portion and a disc-shaped member 5 which can be inserted into the plate-shaped member 5 and is fixed to the roof base 2 by screws 6. A mounting member 7 is provided as a tubular portion. The plate-shaped member 5 is formed by pressing a metal plate, and an insertion hole 8 as a first opening through which the attachment member 7 can be inserted is formed in the central portion of the disk. The outer peripheral side portion of the insertion hole 8 bulges upward, and an adhesive portion 9 as a first sheet fixing portion for fixing the waterproof sheet 3 is provided on the upper surface portion thereof. Therefore, the plate-shaped member 5 and the mounting member 7 form a first member D1 that can be fixed to the roof base 2 by the screw 6.

接着部９は、例えば、ポリエステル系、エチレン酢酸ビニル系、合成ゴム系、オレフィン系等の接着剤からなるホットメルト接着層によって構成されている。接着部９にて防水シート３を固定する場合は、シート固定具１の上方側に防水シート３を被せるように配置した状態で、その防水シート３の上から電磁誘導加熱装置等によって板状部材５を加熱して接着部９のホットメルト接着層を溶融させることで防水シート３を板状部材５に接着することができる。 The adhesive portion 9 is composed of, for example, a hot melt adhesive layer made of a polyester-based adhesive, an ethylene-vinyl acetate-based adhesive, a synthetic rubber-based adhesive, an olefin-based adhesive, or the like. When the waterproof sheet 3 is fixed by the adhesive portion 9, the waterproof sheet 3 is placed on the upper side of the sheet fixture 1 so as to cover the waterproof sheet 3, and a plate-shaped member is used from above the waterproof sheet 3 by an electromagnetic induction heating device or the like. The waterproof sheet 3 can be adhered to the plate-shaped member 5 by heating 5 to melt the hot-melt adhesive layer of the adhesive portion 9.

板状部材５の最外縁部には、接着部９より下段に位置して、断熱材４の上面に接当自在な環状の接地部１０が形成されている（図４参照）。板状部材５における挿通孔８の周囲は、全周にわたって屋根下地２側に凹入された凹入部１１が形成され、その凹入部１１と接着部９との間には、凹入部１１より屋根下地２とは反対側に膨出する環状のリブ部１２が形成されている。 At the outermost edge of the plate-shaped member 5, an annular ground contact portion 10 that is located below the adhesive portion 9 and is accessible to the upper surface of the heat insulating material 4 is formed (see FIG. 4). A recessed portion 11 recessed on the roof base 2 side is formed around the entire circumference of the insertion hole 8 in the plate-shaped member 5, and the roof is formed between the recessed portion 11 and the adhesive portion 9 by the recessed portion 11. An annular rib portion 12 that bulges on the side opposite to the base 2 is formed.

取付部材７は、金属材にて構成されており、図２に示すように、ビス６が挿通される筒状の本体部１３と、本体部１３の上端に設けられ、本体部１３の外径よりも大径に形成された鍔状部１４と、本体部１３の内部下端に設けられ、ビス６の頭部が係止可能な頭部係止部としての座繰り部１５と、を備えている。取付部材７の本体部１３には、周方向に間隔をあけて径方向に挿通する状態で複数（図に示す例では４つ）の開口１６が形成されている。 The mounting member 7 is made of a metal material, and as shown in FIG. 2, the mounting member 7 is provided at the cylindrical main body 13 through which the screw 6 is inserted and at the upper end of the main body 13, and has an outer diameter of the main body 13. It is provided with a flange-shaped portion 14 formed having a larger diameter than the main body portion 13 and a counterbore portion 15 provided at the inner lower end of the main body portion 13 as a head locking portion on which the head of the screw 6 can be locked. There is. A plurality of (four in the example shown in the figure) openings 16 are formed in the main body 13 of the mounting member 7 so as to be inserted in the radial direction at intervals in the circumferential direction.

次に、シート固定具１の設置手順の一例について説明する。
予め、板状部材５と取付部材７とを合体させておく（図３参照）。そして、断熱材４が敷設されている屋根下地２に対してシート固定具１を設置する。設置にあたっては、取付部材７の下端部を断熱材４に突き刺し、取付部材７の内部に挿入したビス６を捻じ込む。この場合、断熱材４における設置対応位置に、予め、取付部材７を挿入する穴を形成しておいてもよい。鍔状部１４が板状部材５の挿通孔８の周囲に形成された凹入部１１に納まるまでビス６を螺進させる。ビス６によって取付部材７が屋根下地２に固定され、取付部材７が板状部材５を押えることにより、板状部材５が固定される。以上の工程でシート固定具１を設置できる。 Next, an example of the installation procedure of the seat fixture 1 will be described.
The plate-shaped member 5 and the mounting member 7 are combined in advance (see FIG. 3). Then, the sheet fixture 1 is installed on the roof base 2 on which the heat insulating material 4 is laid. In the installation, the lower end of the mounting member 7 is pierced into the heat insulating material 4, and the screw 6 inserted inside the mounting member 7 is screwed in. In this case, a hole for inserting the mounting member 7 may be formed in advance at a position corresponding to installation in the heat insulating material 4. The screw 6 is screwed until the flange-shaped portion 14 fits in the recessed portion 11 formed around the insertion hole 8 of the plate-shaped member 5. The mounting member 7 is fixed to the roof base 2 by the screw 6, and the plate-shaped member 5 is fixed by the mounting member 7 pressing the plate-shaped member 5. The seat fixture 1 can be installed by the above steps.

他の箇所にもシート固定具１を設置した後、それらの上から防水シート３を広げて被せるように設置して、防水シート３の弛みをとり、防水シート３の上から、シート固定具１に対応する箇所において、図示しない誘導加熱装置を当て付け、誘導加熱装置による加熱で接着面に塗布された接着部９のホットメルト接着層を溶融させて、防水シート３を接着部９に溶着する。これにより、接着部９に防水シート３が固定され、屋根下地２に、ビス６とシート固定具１を介して、防水シート３が支持される。複数のシート固定具１に接着すれば、防水シート３の固定が完了する。 After installing the sheet fixtures 1 in other places, spread the waterproof sheet 3 over them and install it so as to cover it, remove the slack of the waterproof sheet 3, and put the sheet fixture 1 on the waterproof sheet 3 from above. An induction heating device (not shown) is applied to the portion corresponding to the above, and the hot melt adhesive layer of the adhesive portion 9 applied to the adhesive surface is melted by heating by the induction heating device, and the waterproof sheet 3 is welded to the adhesive portion 9. .. As a result, the waterproof sheet 3 is fixed to the adhesive portion 9, and the waterproof sheet 3 is supported on the roof base 2 via the screw 6 and the sheet fixing tool 1. By adhering to the plurality of sheet fixtures 1, the fixing of the waterproof sheet 3 is completed.

以上のように設置した防水シート３も、年月の経過に伴って劣化するから、長い年月が経過した後には、改修を実施する必要がある。 Since the waterproof sheet 3 installed as described above also deteriorates with the passage of time, it is necessary to carry out repairs after a long period of time has passed.

次に、防水シート３の改修について説明する。
防水シート３の改修を行うときは、図５に示すように、先ず、既に敷設されて固定されている古い防水シート３について、板状部材５における円周状の凹入部１１の外周部に沿って切れ目３ａを入れて切り抜き、切り抜いた部分の防水シート３をシート固定具１から取り除く。そして、図６に示すように、既に設置されている古い板状部材５（以下、下側板状部材という）の上側から重ねるように、新たな改修用の板状部材１７（以下、上側板状部材という）を載置して、連結部１８を用いて下側板状部材５と上側板状部材１７とを連結する。 Next, the repair of the waterproof sheet 3 will be described.
When repairing the waterproof sheet 3, as shown in FIG. 5, first, regarding the old waterproof sheet 3 that has already been laid and fixed, along the outer peripheral portion of the circumferential recess 11 in the plate-shaped member 5.

Then, as shown in FIG. 6, a new plate-shaped member 17 for repair (hereinafter referred to as an upper plate-shaped member) is overlapped from the upper side of the old plate-shaped member 5 (hereinafter referred to as a lower plate-shaped member) that has already been installed. A member) is placed, and the lower plate-shaped member 5 and the upper plate-shaped member 17 are connected by using the connecting portion 18.

上側板状部材１７は、下側板状部材５と同じ構成であり、金属板をプレス加工によって成形してあり、円板の中央部分に第二開口部としての挿通孔１９が設けられている。その挿通孔１９の外周側の部分が上方に膨出しており、その上面部分に、防水シート３が固定される第二シート固定部としてのホットメルト接着層からなる接着部２０が設けられている。この上側板状部材１７の挿通孔１９が下側板状部材５の挿通孔８とが重なり合うように、上側板状部材１７を下側板状部材５の上に載置する。そして、載置されている上側板状部材１７の上側から、連結部１８を装着する。
従って、上側板状部材１７により、第一部材Ｄ１に連結されることで屋根下地２に固定可能な第二部材Ｄ２が構成されている。 The upper plate-shaped member 17 has the same structure as the lower plate-shaped member 5, a metal plate is formed by press working, and an insertion hole 19 as a second opening is provided in the central portion of the disk. The outer peripheral side portion of the insertion hole 19 bulges upward, and an adhesive portion 20 made of a hot melt adhesive layer as a second sheet fixing portion for fixing the waterproof sheet 3 is provided on the upper surface portion thereof. .. The upper plate-shaped member 17 is placed on the lower plate-shaped member 5 so that the insertion hole 19 of the upper plate-shaped member 17 overlaps with the insertion hole 8 of the lower plate-shaped member 5. Then, the connecting portion 18 is attached from above the upper plate-shaped member 17 on which the member is placed.
Therefore, the upper plate-shaped member 17 constitutes a second member D2 that can be fixed to the roof base 2 by being connected to the first member D1.

連結部１８は、径方向に拡径可能に構成された筒状の外側部材２１と、外側部材２１の内部に上下方向に挿通されることで、外側部材２１を拡径させる軸状の内側部材２２とが備えられている。 The connecting portion 18 has a cylindrical outer member 21 that is configured to be able to expand the diameter in the radial direction, and a shaft-shaped inner member that expands the diameter of the outer member 21 by being inserted vertically inside the outer member 21. 22 is provided.

外側部材２１は、合成樹脂により一体成形にて構成されており、図６、８に示すように、円環状に形成された鍔部２３と、周方向に間隔をあけて鍔部２３から軸方向に沿って片持ち状に延びる複数（図６に示す例では４個）の脚部２４とが備えられている。脚部２４は、周方向に幅広で且つ径方向に幅狭の帯板状のアーム部２４Ａと、アーム部２４Ａの下部に位置して内側部材２２の外方への抜け外れを阻止する係止部２４Ｂとを備えている。 The outer member 21 is integrally molded with a synthetic resin, and as shown in FIGS. A plurality of (4 in the example shown in FIG. 6) leg portions 24 extending in a cantilever shape are provided. The legs 24 are a strip-shaped arm portion 24A that is wide in the circumferential direction and narrow in the radial direction, and a locking that is located below the arm portion 24A and prevents the inner member 22 from coming off outward. It is provided with a part 24B.

鍔部２３は、上側板状部材１７の挿通孔１９よりも大径であり、上側板状部材１７の挿通孔１９の外周部に載置可能に設けられている。複数の脚部２４は、径方向外方側が本体部１３の内周面に対応する位置に設けられている。外側部材２１が、上側板状部材１７の挿通孔１９を通して取付部材７に差し込まれると、複数の脚部２４が本体部１３の内周面に摺接案内されながら嵌り合い、鍔部２３が上側板状部材１７の挿通孔１９の外周部に載置された状態で装着される。 The collar portion 23 has a diameter larger than that of the insertion hole 19 of the upper plate-shaped member 17, and is provided so as to be mounted on the outer peripheral portion of the insertion hole 19 of the upper plate-shaped member 17. The plurality of leg portions 24 are provided at positions where the outer side in the radial direction corresponds to the inner peripheral surface of the main body portion 13. When the outer member 21 is inserted into the mounting member 7 through the insertion hole 19 of the upper plate-shaped member 17, the plurality of leg portions 24 are fitted to the inner peripheral surface of the main body portion 13 while being slidably guided, and the collar portion 23 is raised. It is mounted in a state of being placed on the outer peripheral portion of the insertion hole 19 of the side plate-shaped member 17.

内側部材２２は、合成樹脂により一体成形にて中心部に軸部２５，２６を備えた略軸状に形成され、外側部材２１の内部に挿通孔２７（図６参照）を通して上下方向に差し込み装着可能に設けられている。そして、内側部材２２は、外側部材２１に差し込み挿入されることで、外側部材２１に対して軸方向での位置保持がされるように構成されている。 The inner member 22 is integrally molded with synthetic resin to form a substantially shaft shape having shaft portions 25 and 26 at the center, and is inserted and mounted in the vertical direction through an insertion hole 27 (see FIG. 6) inside the outer member 21. It is provided as possible. The inner member 22 is configured to hold the position in the axial direction with respect to the outer member 21 by being inserted into the outer member 21.

すなわち、図６，８に示すように、内側部材２２には、軸方向先端側、及び、軸方向の中間部に、夫々、差し込み挿入に伴って脚部２４の係止部２４Ｂに係止して、外方側への抜け外れを阻止する抜け止め用の係止部２８，２９が設けられている。先端側の係止部２８及び中間側の係止部２９は、いずれも周方向全域に亘って係止用の段差を形成している。先端側の係止部２８と中間側の係止部２９との間に位置する先端側の軸部２５は、中間側の係止部２６よりも上方側に位置する基端側の軸部２６よりも小径に設けられている。内側部材２２の周囲には、周方向に間隔をあけて位置合わせ用のリブ３０が形成されている。基端側の軸部に設けられるリブ３０は、外側部材２１の内部に挿通孔２７に嵌り合うように設けられている。 That is, as shown in FIGS. Therefore, locking portions 28 and 29 for preventing the pull-out to prevent the slip-off to the outside side are provided. Both the locking portion 28 on the tip side and the locking portion 29 on the intermediate side form a step for locking over the entire circumferential direction. The tip-side shaft portion 25 located between the tip-side locking portion 28 and the intermediate-side locking portion 29 is a base-end-side shaft portion 26 located above the intermediate-side locking portion 26. It is provided with a smaller diameter than. Ribs 30 for positioning are formed around the inner member 22 at intervals in the circumferential direction. The rib 30 provided on the shaft portion on the base end side is provided inside the outer member 21 so as to fit into the insertion hole 27.

外側部材２１が取付部材７に差し込み装着された状態で、内側部材２２を上方側から手作業により押し込みながら外側部材２１に挿通させると、図７，８に示すように、内側部材２２の中間側の係止部２９が脚部２４の係止部２４Ｂに弾性的に係合して抜け外れを防止することができる。このとき、基端側の軸部２６が大径に設けられていることから、弾性変形により外側部材２１の脚部２４が径方向外方に押し広げられ、径方向外方側に拡径される。 With the outer member 21 inserted into the mounting member 7 and inserted into the outer member 21 while manually pushing the inner member 22 from above, the intermediate side of the inner member 22 is shown in FIGS. 7 and 8. The locking portion 29 of the above can be elastically engaged with the locking portion 24B of the leg portion 24 to prevent the leg portion 24 from coming off. At this time, since the shaft portion 26 on the base end side is provided with a large diameter, the leg portion 24 of the outer member 21 is expanded outward in the radial direction due to elastic deformation, and the diameter is expanded outward in the radial direction. NS.

外側部材２１に対して内側部材２２に差し込み挿入して、脚部を径方向外方に押し広げようとする際に、脚部２４と取付部材７の本体部１３に形成された開口１６とが周方向に位置がずれていると、脚部２４が拡径できない。そのときは、外側部材２１を回動させて周方向に位置合わせしながら、内側部材２２を挿通させる。 When the leg portion is inserted into the inner member 22 with respect to the outer member 21 and the leg portion is to be pushed outward in the radial direction, the leg portion 24 and the opening 16 formed in the main body portion 13 of the mounting member 7 are formed. If the position is deviated in the circumferential direction, the diameter of the leg portion 24 cannot be expanded. At that time, the inner member 22 is inserted while rotating the outer member 21 and aligning the outer member 21 in the circumferential direction.

そして、内側部材２２の挿通に伴って、脚部２４の抜け外れ防止用の係止部２４Ｂが、内側部材２２における軸方向の中間部に位置する受止め部２９に係止して位置保持状態に切り換わり、差し込み装着が完了する。その状態で内側部材２２の抜け外れが阻止される。 Then, as the inner member 22 is inserted, the locking portion 24B for preventing the leg portion 24 from coming off is locked to the receiving portion 29 located at the intermediate portion in the axial direction of the inner member 22 to hold the position. It switches to, and the insertion and installation is completed. In that state, the inner member 22 is prevented from coming off.

内側部材２２の挿入に伴って脚部２４が拡径されると、脚部２４は取付部材７の本体部１３に形成された開口１６の内部を通して径方向外方に張り出した状態となる。その結果、外側部材２１の脚部２４が本体部１３の開口１６の上縁１６ａ（係止部の一例）に係止して、外側部材２１が取付部材７に対して抜け外れが阻止される状態となる。その結果、外側部材２１の鍔部２３により上側板状部材１７が押えられて、下側板状部材５と上側板状部材１７とが連結される。 When the diameter of the leg portion 24 is increased with the insertion of the inner member 22, the leg portion 24 is in a state of projecting outward in the radial direction through the inside of the opening 16 formed in the main body portion 13 of the mounting member 7. As a result, the leg portion 24 of the outer member 21 is locked to the upper edge 16a (an example of the locking portion) of the opening 16 of the main body portion 13, and the outer member 21 is prevented from coming off from the mounting member 7. It becomes a state. As a result, the upper plate-shaped member 17 is pressed by the flange portion 23 of the outer member 21, and the lower plate-shaped member 5 and the upper plate-shaped member 17 are connected to each other.

このようにして、連結部１８を用いて下側板状部材５と上側板状部材１７とが連結され、この状態で改修された防水シート３による防水作用が発揮される。 In this way, the lower plate-shaped member 5 and the upper plate-shaped member 17 are connected by using the connecting portion 18, and the waterproofing action of the repaired waterproof sheet 3 is exhibited in this state.

しかしながら、防水シート３を敷設した状態では、防水シート３は、シート固定具１の設置箇所以外の範囲では断熱材４の上に載置されているだけの状態となっているから、例えば風による揚力の作用や他の要因により防水シート３がバタつく現象を生じる場合がある。そのような場合、防水シートの動きが連結部１８に伝わり、内側部材２２と外側部材２１との係止箇所が摩耗したり、変形すること等に起因して、内側部材２２の中間部側の受止め部２９と外側部材２１の脚部２４との係止が外れてしまうおそれがある。 However, in the state where the waterproof sheet 3 is laid, the waterproof sheet 3 is only placed on the heat insulating material 4 in a range other than the installation location of the sheet fixture 1, and therefore, for example, due to wind. The waterproof sheet 3 may flutter due to the action of lift or other factors. In such a case, the movement of the waterproof sheet is transmitted to the connecting portion 18, and the locking portion between the inner member 22 and the outer member 21 is worn or deformed. There is a risk that the receiving portion 29 and the leg portion 24 of the outer member 21 will be disengaged.

このように内側部材２２の中間部側の受止め部２９と外側部材２１の脚部２４との係止が外れた場合であっても、図８に示すように、外側部材２１の脚部２４が先端側に位置する受止め部２８に係止して内側部材２２の抜け外れが阻止される。 Even when the receiving portion 29 on the intermediate portion side of the inner member 22 and the leg portion 24 of the outer member 21 are unlocked in this way, as shown in FIG. 8, the leg portion 24 of the outer member 21 is released. Is locked to the receiving portion 28 located on the tip side to prevent the inner member 22 from coming off.

このとき、上記したような先端側の受止め部２８が設けられていなければ、上記したような風による揚力の作用等により、内側部材２２が抜け外れて大きく上方に持ち上げられてしまうことがある。そうすると、内側部材２２が斜め姿勢になって、上方側から踏みつけられたり、他物が乗りかかったりすると、防水シートが破損してしまうおそれがある。 At this time, if the receiving portion 28 on the tip side as described above is not provided, the inner member 22 may come off and be lifted significantly upward due to the action of lift due to the wind as described above. .. Then, if the inner member 22 is in an oblique posture and is trampled from above or is hit by another object, the waterproof sheet may be damaged.

これに対して、上記構成では、外側部材２１の脚部２４が先端側に位置する受止め部２８に係止するため、内側部材２２が大きく上方に持ち上げられることがなく、上述のような防水シートの破損を防止し易いものになる。 On the other hand, in the above configuration, since the leg portion 24 of the outer member 21 is locked to the receiving portion 28 located on the tip side, the inner member 22 is not significantly lifted upward, and the waterproof as described above. It becomes easy to prevent the sheet from being damaged.

他の箇所におけるシート固定具１についても、同様に、上側板状部材１７を設置した後、それらの上から改修用の新たな防水シート３を広げて被せるように設置する。そして、防水シート３の弛みをとり、防水シート３の上から、新たに設置された上側板状部材１７に対応する箇所において、図示しない誘導加熱装置を当て付け、誘導加熱装置による加熱で上側板状部材１７の接着部２０に塗布されたホットメルト接着層を溶融させて、防水シート３を接着部２０に溶着する。これにより、接着部２０に防水シート３が固定され、屋根下地２に、上側板状部材１７、連結部１８、下側板状部材５、取付部材７、ビス６を介して、防水シート３が支持される。複数のシート固定具１に接着すれば、改修用の防水シート３の固定が完了する。 Similarly, for the sheet fixing tool 1 at other locations, after installing the upper plate-shaped member 17, a new waterproof sheet 3 for repair is spread over them and installed so as to cover them. Then, the slack of the waterproof sheet 3 is removed, and an induction heating device (not shown) is applied to the newly installed upper plate-shaped member 17 from above the waterproof sheet 3, and the upper plate is heated by the induction heating device. The hot melt adhesive layer applied to the adhesive portion 20 of the shaped member 17 is melted, and the waterproof sheet 3 is welded to the adhesive portion 20. As a result, the waterproof sheet 3 is fixed to the adhesive portion 20, and the waterproof sheet 3 is supported on the roof base 2 via the upper plate-shaped member 17, the connecting portion 18, the lower plate-shaped member 5, the mounting member 7, and the screw 6. Will be done. By adhering to the plurality of sheet fixtures 1, the fixing of the waterproof sheet 3 for repair is completed.

上記したような構成のシート固定具１であれば、改修作業を行う場合、既に設置されている取付部材７に対して、外側部材２１を挿通させたのち、内側部材２２を押し込みながら差し込み装着させるだけの簡単な作業で対応できる。 With the seat fixture 1 having the above configuration, when performing repair work, the outer member 21 is inserted through the already installed mounting member 7, and then the inner member 22 is pushed in and mounted. It can be handled with just a simple task.
