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 fixing device for fixing a waterproof sheet provided along a waterproof base to a 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 a waterproof sheet fastener of this type, for example, a fixing portion (hot melt adhesive layer) capable of adhering and fixing a waterproof sheet is provided on the upper surface of a fastener body made of a metal disk A screw insertion hole is formed in a central portion of the housing, and a screw member inserted into the screw insertion hole is configured 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。   For fixing the waterproof sheet to the waterproof sheet fixture, for example, put a waterproof sheet from the top of the waterproof sheet fixture installed on the waterproof base, and heat the fixture body from above using the electromagnetic induction heating device. Then, the adhesive layer on the fixing portion described above is melted, and the waterproof sheet is fixed to the fixing device main 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。
And when repairing the waterproof sheet installed as mentioned above, for example, in the location which shifted sideways from the plane position of the waterproof sheet fixing tool already installed, the new for the repair from the top of the waterproof sheet There is a method (hereinafter, referred to as a first method) which is implemented by installing a waterproof sheet fixing tool and bonding a repair waterproofing sheet from above the waterproof sheet fixing tool.
However, according to this repair method, when installing the waterproof sheet fixing tool for repair, it is necessary to install a screw member on the waterproof base, and the noise and vibration accompanying the work propagate to the waterproof base, and it is environmentally 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 proposed as a method of modifying the noise and vibration problem. That is, the waterproof sheet is cut along the periphery of the waterproof sheet fixture already installed, and the waterproof sheet fixture is reheated to melt the adhesive layer of the fixed portion, and the waterproof sheet portion in which the cut is inserted is After removing from the tarpaulin fixing tool, the tarpaulin fixing tool exposed in the cutout part is used as it is, a new adhesive layer is provided on it, and a waterproofing sheet for repair is laid from above to waterproof It is a method (henceforth the 2nd method) to adhere to a sheet fixing tool (for example, refer to patent documents 1).

特開2002−88986号公報JP, 2002-88986, A

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。   In the case of using the above-mentioned conventional waterproof sheet fixing tool, if the waterproof sheet is repaired according to the first method, noise and vibration occur with the installation of the screw member as described above, which is not preferable from the environment. There's a problem. In addition, if the waterproof sheet is remodeled by the second method, it takes much time and effort to reliably remove the old adhesive layer from the fixing portion of the waterproof sheet fixing tool, and the work efficiency of the waterproof sheet repair decreases. There is a problem. If the old adhesive layer is not removed, there is a possibility that the adhesive performance can not be sufficiently exhibited even if a new adhesive layer is applied thereon.

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 a new adhesive layer, it is conceivable to remove the screw member and replace the entire waterproof sheet fixing tool with a new one. Once the threaded member is removed, the plug anchor may be loosened, and even if the threaded member is screwed on 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 fixing device capable of efficiently performing a waterproof sheet repair work while solving the above 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 fixing device according to the present invention is
A waterproof sheet fixing device for fixing a waterproof sheet laid on a waterproof base to the waterproof base,
A first member having a first sheet fixing portion and fixable to the waterproof base by a nail or a screw;
A second member fixable to the waterproof foundation by being connected to the first member in a state of being disposed above the first member while having a second sheet fixing portion;
A connecting portion connecting the first member and the second member;
A first opening through which the nail or the screw can be inserted is formed in the first member,
A second opening is formed in the second member at a position corresponding to the first opening,
The connecting portion is provided so as to extend between the first opening and the second opening, and connects the first member and the second member.

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. And when remodeling to a new waterproof sheet with progress of years, the part corresponding to the first opening of the first member is cut out of the old waterproof sheet, and the second opening is made to correspond to the first opening. The second member is placed from the upper side in the state where the part is positioned, and the first member and the second member are connected by the connecting portion provided so as to extend between 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, there is no need to drill a new attachment hole in the waterproof base. As a result, it is possible to avoid the generation of noise, vibration and the like associated with the work of drilling a new mounting hole.

Instead of this configuration, for example, as a configuration for connecting the first member and the second member, a screw or the like is disposed at a plurality of locations distributed along the circumferential direction at locations separated radially from the first opening. However, in such a configuration, the number of connection points may be increased, which may make the installation operation troublesome. On the other hand, the said connection part can fix both by simple connection structure by setting it as the structure which connects a 1st member and a 2nd member using the structure of a 1st opening part. .

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 come to be able to provide a waterproof sheet fixing tool capable of efficiently performing a waterproof sheet repair work by a simple connection structure while suppressing the generation of noise and vibration.

Next, an example of the installation procedure of the sheet fixture 1 will be described.
The plate-like member 5 and the mounting member 7 are united 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. At the time of installation, the lower end portion of the mounting member 7 is pierced into the heat insulating material 4 and the screw 6 inserted into the inside of the mounting member 7 is screwed. In this case, a hole into which the mounting member 7 is inserted may be formed in advance at the installation corresponding position in the heat insulating material 4. The screw 6 is screwed in until the hooked portion 14 is received in the recessed portion 11 formed around the insertion hole 8 of the plate-like member 5. The mounting member 7 is fixed to the roof base 2 by the screw 6, and the mounting member 7 presses the plate-like member 5 to fix the plate-like member 5. The sheet fixing tool 1 can be installed by the above process.

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 fasteners 1 at other places, install the waterproof sheet 3 from above them and install them, remove the slack of the waterproof sheet 3, and place the sheet fastener 1 on the waterproof sheet 3. In the part corresponding to the above, an induction heating device (not shown) is applied, and the hot melt adhesive layer of the adhesive portion 9 applied to the adhesive surface is melted by heating by the induction heater to weld the waterproof sheet 3 to the adhesive portion 9 . As a result, the waterproof sheet 3 is fixed to the bonding portion 9, and the waterproof sheet 3 is supported on the roof base 2 via the screw 6 and the sheet fixture 1. If it adhere | attaches the several sheet fixing tool 1, fixation of the waterproof sheet 3 will be 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 years, it is necessary to carry out a repair 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 the waterproof sheet 3 is to be repaired, first, as shown in FIG. 5, the old waterproof sheet 3 which has already been laid and fixed is extended along the outer peripheral portion of the circumferential recess 11 in the plate member 5. The cut 3a is inserted and cut out, and the waterproof sheet 3 of the cut out portion is removed from the sheet fixture 1. And as shown in FIG. 6, the plate-like member 17 for new repair (following, upper side plate shape) so that it may overlap from the upper side of the old plate-like member 5 (following, lower side plate-like member) installed already. The lower plate-like member 5 and the upper plate-like member 17 are connected by using the connecting portion 18 while placing the member).

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-like member 17 has the same configuration as the lower plate-like member 5, and 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 disc. An outer peripheral portion of the insertion hole 19 bulges upward, and an upper surface portion is provided with an adhesive portion 20 formed of a hot melt adhesive layer as a second sheet fixing portion to which the waterproof sheet 3 is fixed. . The upper plate-like member 17 is placed on the lower plate-like member 5 such that the insertion holes 19 of the upper plate-like member 17 overlap with the insertion holes 8 of the lower plate-like member 5. And the connection part 18 is mounted | worn from the upper side of the upper side plate-like member 17 mounted.
Therefore, the second member D2 that can be fixed to the roof foundation 2 by being connected to the first member D1 by the upper plate-like member 17 is configured.

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 is a cylindrical outer member 21 configured to be radially expanded in diameter, and a shaft-like inner member for expanding the outer member 21 by being vertically inserted through the inside of the outer member 21. And 22 are 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 formed of a synthetic resin, and as shown in FIGS. 6 and 8, the outer member 21 and the annular portion 23 are circumferentially spaced apart from each other in the axial direction from the ridge portion 23. And a plurality of (four in the example shown in FIG. 6) legs 24 extending in a cantilever manner. The leg portion 24 is a strip-shaped arm portion 24A which is wide in the circumferential direction and narrow in the radial direction, and a locking portion which is located at a lower portion of the arm portion 24A and which prevents the inner member 22 from coming off. And a unit 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 is larger in diameter than the insertion hole 19 of the upper plate-like member 17 and is provided so as to be able to be mounted on the outer peripheral portion of the insertion hole 19 of the upper plate-like member 17. The plurality of leg portions 24 are provided at positions where the radially outer side 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 17, the plurality of legs 24 are fitted while being slidably guided on the inner peripheral surface of the main body 13, and the hook 23 is the upper It mounts | wears with the state mounted in the outer peripheral part of the penetration hole 19 of the side plate-like member 17. As shown in FIG.

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 formed in a substantially shaft shape having the shaft portions 25 and 26 at the center by integral molding of synthetic resin, and inserted in the vertical direction through the insertion hole 27 (see FIG. 6) inside the outer member 21 It is possible. The inner member 22 is configured to be held in position in the axial direction with respect to the outer member 21 by being inserted and 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. 6 and 8, the inner member 22 is engaged with the locking portion 24B of the leg 24 along with the insertion and insertion on the axial distal end side and the axial middle portion, respectively. Thus, there are provided locking portions 28, 29 for preventing the outward removal. Both the distal end side locking portion 28 and the middle side locking portion 29 form a level difference for locking over the entire circumferential direction. The distal end side shaft portion 25 positioned between the distal end side locking portion 28 and the middle side locking portion 29 is a proximal end side shaft portion 26 positioned above the middle side locking portion 26. It has a smaller diameter than that. Positioning ribs 30 are formed around the inner member 22 at intervals in the circumferential direction. The rib 30 provided on the proximal end side shaft portion 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。   When the outer member 21 is inserted into the outer member 21 while manually pushing the inner member 22 from above with the outer member 21 inserted and attached to the attachment member 7, as shown in FIGS. 7 and 8, the middle side of the inner member 22. The hooking portion 29 elastically engages with the hooking portion 24B of the leg 24 to prevent it from coming off. At this time, since the proximal end side shaft portion 26 is provided with a large diameter, the leg portion 24 of the outer member 21 is pushed outward in the radial direction by elastic deformation, and the diameter is enlarged outward in the radial direction. Ru.

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。   The leg 24 and the opening 16 formed in the main body 13 of the mounting member 7 when inserting and inserting the outer member 21 into the inner member 22 and trying to spread the leg outward in the radial direction When the position is shifted in the circumferential direction, the diameter of the leg portion 24 can not be increased. At this time, the inner member 22 is inserted while rotating the outer member 21 to align 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, with the insertion of the inner member 22, the locking portion 24B for preventing the detachment of the leg portion 24 is locked to the receiving portion 29 positioned at the axial intermediate portion of the inner member 22 to hold the position. The insertion and installation is complete. In this 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 leg portion 24 is expanded in diameter with the insertion of the inner member 22, the leg portion 24 radially outwardly protrudes 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 13, and the outer member 21 is prevented from coming off with respect to the mounting member 7 It becomes a state. As a result, the upper plate-like member 17 is pressed by the flange portion 23 of the outer member 21, and the lower plate-like member 5 and the upper plate-like member 17 are connected.

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。   Thus, the lower side plate-like member 5 and the upper side plate-like member 17 are connected using the connecting portion 18, and the waterproof function by the waterproof sheet 3 repaired in this state is exhibited.

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, since the waterproof sheet 3 is only placed on the heat insulating material 4 in the range other than the installation place of the sheet fixture 1, for example, by the wind The waterproof sheet 3 may be fluttered due to the action of lift force and other factors. In such a case, the movement of the waterproof sheet is transmitted to the connecting portion 18, and the engagement between the inner member 22 and the outer member 21 is worn or deformed, etc. There is a risk that the engagement between the receiving portion 29 and the leg portion 24 of the outer member 21 may be released.

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。   As shown in FIG. 8, even when the engagement between the receiving portion 29 on the middle portion side of the inner member 22 and the leg portion 24 of the outer member 21 is released as described above, the leg portion 24 of the outer member 21 is Is locked to the receiving portion 28 located on the distal end 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 front end side receiving portion 28 as described above is not provided, the inner member 22 may be detached and lifted up largely due to the action of the lift force by the wind as described above, etc. . In this case, if the inner member 22 is in an oblique position and is stepped on from above or another object gets on the waterproof sheet, 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, the leg 24 of the outer member 21 is engaged with the receiving portion 28 positioned on the tip end, so the inner member 22 is not largely lifted upward, and the waterproof as described above It becomes easy to prevent breakage of the sheet.

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, with regard to the sheet fasteners 1 at other places, after the upper plate-like members 17 are installed, a new waterproof sheet 3 for repair is installed so as to be spread over them. Then, take the slack of the waterproof sheet 3 and apply an induction heating device (not shown) to the upper portion of the waterproof sheet 3 at a position corresponding to the newly installed upper plate-like member 17 and heat the induction heating device to heat the upper plate. The hot melt adhesive layer applied to the adhesive portion 20 of the second member 17 is melted to weld the waterproof sheet 3 to the adhesive portion 20. Thus, the waterproof sheet 3 is fixed to the bonding portion 20, and the waterproof sheet 3 is supported on the roof base 2 via the upper plate member 17, the connecting portion 18, the lower plate member 5, the mounting member 7, and the screw 6. Be done. If it adhere | attaches several sheet fixing tools 1, fixation 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。   In the case of the sheet fixing tool 1 having the above-described configuration, when the repair work is performed, the outer member 21 is inserted through the mounting member 7 already installed, and then the inner member 22 is inserted and inserted while being inserted. We can cope with just simple task.

〔別実施形態〕

At the inner peripheral portion of the boss member 36, a female screw portion 39 to which the screw 37 can be screwed is formed.

上側板状部材17は、円板状であり、その中央部分に第二開口部としての挿通孔19が設けられ、且つ、挿通孔19の外周側にホットメルト接着層からなる接着部20が設けられる点は、上記実施形態と同じである。しかし、この上側板状部材17における挿通孔19は、ビス37のネジ部37Aは挿通するが、ビス37の頭部37Bは挿通できない程度の大きさに形成されている。ビス37は皿ビスにて構成され、上側板状部材17における挿通孔19の周囲には座繰り部19aが形成されている。   The upper plate-like member 17 has a disk shape, and is provided with an insertion hole 19 as a second opening at its central portion, and an adhesion portion 20 made of a hot melt adhesive layer is provided on the outer peripheral side of the insertion hole 19 The points to be done are the same as in the above embodiment. However, the insertion hole 19 in the upper plate-like member 17 is formed in such a size that the screw portion 37A of the screw 37 can be inserted but the head 37B of the screw 37 can not be inserted. The screw 37 is formed by a countersunk screw, and a counterbored portion 19 a is formed around the insertion hole 19 in the upper plate-like member 17.

防水シート3の改修作業を行う場合には、図11に示すように、シート固定具1で固定されている箇所の中央部にて周方向に切れ目3aを入れて切り抜き、切り抜いた部分の防水シート3を取り除く。そして、図12に示すように、下側板状部材5の上側から重ねるように、上側板状部材17を載置して、上方側からビス37を挿通し、ボス部材36の雌ネジ部39に螺合装着して固定する。そのとき、ボス部材36を筒状の本体部13の上端よりも少し低い位置までネジ込み、上側板状部材17の座繰り部19aが入り込むようにしている。そして、それらの上から改修用の新たな防水シート3を広げて被せて、接着部20に熱溶着により固定する点は上記実施形態と同じである。   When the waterproof sheet 3 is to be repaired, as shown in FIG. 11, the waterproof sheet of the cut out portion is formed by cutting the cut 3 a in the circumferential direction at the center of the portion fixed by the sheet fixture 1. Remove 3 Then, as shown in FIG. 12, the upper plate-like member 17 is placed so as to overlap from the upper side of the lower plate-like member 5, and the screw 37 is inserted from the upper side to the female screw portion 39 of the boss member 36. Screw on and fix. At that time, the boss member 36 is screwed to a position slightly lower than the upper end of the cylindrical main body portion 13 so that the counterbore portion 19a of the upper plate-like member 17 is inserted. And the point which spreads and covers the new waterproof sheet 3 for repair from on the top, and fixes to the adhesion part 20 by heat welding is the same as the said embodiment.

(3)上記実施形態では、改修用の新たな防水シート3を、上側板状部材17に設けられた接着部20に熱溶着により固定する構成としたが、この構成に代えて、例えば、図13に示すように、改修用の新たな防水シート3の上方側から上側板状部材17を取り付けて連結部18(具体的にはビス40)により下側板状部材5に連結することにより、防水シート3を押えて固定する構成としてもよい。この構成では、上側板状部材17は、平らな円板状に形成され、中央にビス40だけが通過可能な挿通孔が形成されている。ビス40は、皿ビスにて構成され、上側板状部材17の挿通孔には座繰り部が形成されている。そして、上側板状部材17を取付けた状態では、上側板状部材17やビス40が露出するので、上側板状部材17よりも一回り大きい防水カバー体41により覆うようにするとよい。防水カバー体41は、上側板状部材17の外表面に接着剤等によって貼り付けて固定するとよい。 (3) In the above embodiment, the new waterproof sheet 3 for repair is fixed to the adhesive portion 20 provided on the upper plate-like member 17 by thermal welding, but instead of this configuration, for example, as shown in FIG.
