Description
この発明は、陸屋根又はバルコニー床等の上面に防水シートが敷設された陸屋根住宅等において、防水シートを貫通して設置された各種支柱等の防水構造に関する。 The present invention relates to a waterproof structure such as various columns installed through a waterproof sheet in a flat roof house or the like in which a waterproof sheet is laid on the upper surface of a flat roof or a balcony floor.
従来より、陸屋根又は屋上バルコニーの床などを、支柱等の貫通部材が貫通して設置されることがある。そのようにして設置される支柱の例としては、アンテナ設置用のアンテナ支線を取り付けるための支柱、バルコニーの控え柱を立てるための支柱、屋上に登るための梯子の一端を固定するための支柱、太陽光発電パネル等の架台の柱脚を立てるための支柱、又はメンテナンス作業時の命綱を取り付けるための支柱などが挙げられる。 Conventionally, a penetrating member such as a column may be installed through a flat roof or a floor of a rooftop balcony. Examples of pillars installed in this way include a pillar for attaching an antenna branch line for antenna installation, a pillar for raising a balcony pillar, a pillar for fixing one end of a ladder for climbing the rooftop, A column for standing a column base of a pedestal such as a photovoltaic power generation panel or a column for attaching a lifeline at the time of maintenance work can be mentioned.
ここで、屋根又は床の上面に塩化ビニル樹脂などからなる防水シートが敷設されている場合は、上記の各種支柱等は防水シートを貫通することとなるため、その貫通部の水密性を確保するために何らかの防水処理を施す必要がある。 Here, when a waterproof sheet made of vinyl chloride resin or the like is laid on the top surface of the roof or floor, the above-mentioned various support pillars penetrate the waterproof sheet, so that the water tightness of the penetration portion is ensured. Therefore, it is necessary to apply some waterproofing treatment.
例えば、図7には、そのような防水シートの貫通部における従来の防水構造を示している。この従来例においては、アンテナ支線を取り付けるための支柱(51)が、陸屋根上面に敷設された防水シート(14)を貫通して設置されている。そして、円筒状の支柱本体(52)の貫通部には、円筒状の筒状防水部(56)とその筒状防水部(56)の周壁下端より外方に向かって張り出すフランジ部(57)とからなる防水部材(55)が設置されている。すなわち、防水部材(55)の筒状防水部(56)を支柱本体(52)に外嵌させることにより、支柱本体(2)外周面の露出部分を筒状防水部(56)で覆うとともに、フランジ部(57)下面を防水シート(14)の上面に載置した状態で溶着等により固定する。 For example, FIG. 7 shows a conventional waterproof structure in a penetration portion of such a waterproof sheet. In this conventional example, a column (51) for attaching an antenna branch line is installed through a waterproof sheet (14) laid on the upper surface of a flat roof. A cylindrical cylindrical waterproofing portion (56) and a flange portion (57) projecting outward from the lower end of the peripheral wall of the cylindrical waterproofing portion (56) are formed in the penetrating portion of the cylindrical column main body (52). ) Is provided. That is, by fitting the cylindrical waterproof part (56) of the waterproof member (55) to the column main body (52), the exposed part of the outer peripheral surface of the column main body (2) is covered with the cylindrical waterproof unit (56), The lower surface of the flange portion (57) is fixed by welding or the like with the lower surface being placed on the upper surface of the waterproof sheet (14).
この防水部材(55)は、防水シート(14)と同様の材質のものを材料として現場で加工して成形されており、材料の接合部分は防水施工業者によって溶着等の止水処理がなされている。さらに、筒状防水部(56)の外周面上端部と支柱本体(52)の上端に連結された基台(53)下面とに跨ってシーリング材(60)を付着することにより、支柱本体(52)の貫通部の水密性を確保するようにしている。 This waterproof member (55) is processed and molded on site using the same material as the waterproof sheet (14), and the joint portion of the material is subjected to water-stop treatment such as welding by a waterproofing contractor. Yes. Furthermore, by attaching the sealing material (60) across the upper end of the outer peripheral surface of the cylindrical waterproof part (56) and the lower surface of the base (53) connected to the upper end of the column main body (52), the column main body ( The water-tightness of the penetration part of 52) is ensured.
なお、特許文献1には、メンテナンス作業時の命綱を取り付けるための支柱について、図7と同様の防水構造が開示されている。 Note that Patent Document 1 discloses a waterproof structure similar to that shown in FIG. 7 for a support for attaching a lifeline during maintenance work.
しかし、図7に示す防水部材(55)は経年によって収縮するため、筒状防水部(56)の上端高さが次第に低くなってしまい、それに伴って、筒状防水部(56)上端部に付着されたシーリング材(60)が、下方へ引っ張られて切れ目が発生しやすくなってしまう。また、シーリング材(60)は、その断面形状が三角形状となるような状態で施工されているため、防水部材(55)の収縮に関わらず切れ目が生じやすくなっており、シーリング部分の防水性能を改善する必要があった。 However, since the waterproof member (55) shown in FIG. 7 shrinks over time, the upper end height of the cylindrical waterproof part (56) gradually decreases, and accordingly, the upper end part of the cylindrical waterproof part (56) The adhering sealant (60) is pulled downward, and breaks are likely to occur. In addition, the sealing material (60) is constructed so that its cross-sectional shape is a triangular shape, so breakage is likely to occur regardless of the shrinkage of the waterproofing member (55), and the waterproof performance of the sealing part There was a need to improve.
さらに、防水部材(55)は、上記のように現場加工によって成形する必要があるため施工性が悪く、その現場加工における接合部分の防水性能は、防水施工業者の技量に委ねざるを得なかった。 Furthermore, since the waterproof member (55) needs to be molded by on-site processing as described above, the workability is poor, and the waterproof performance of the joint portion in the on-site processing has to be left to the skill of the waterproof construction contractor. .
そこで、この発明は、上記の不具合を解消して、屋根等の上面の防水シートを支柱等の貫通部材が貫通する構造において、その貫通部における防水性能を高めるとともに、施工性を向上させることができる防水構造を提供することを目的とする。 In view of this, the present invention eliminates the above-mentioned problems, and in a structure in which a penetrating member such as a support penetrates a waterproof sheet on the upper surface of a roof or the like, it can improve waterproof performance at the penetrating portion and improve workability. An object of the present invention is to provide a waterproof structure.
上記の課題を解決するため、この発明の防水構造は、支柱等の貫通部材が、屋根若しくは床の上面に敷設された防水シートを貫通して設けられ、その防水シート上面より上側の露出部分において貫通部材外周面が筒状の防水部に覆われた構造であって、その筒状防水部が下方へずれるのを防止する位置決め部が、筒状防水部の周壁上端部より内方に向かって突設されて、貫通部材の上端面に載置され、アンテナ支線等を取り付けるための取付金具、バルコニー等の控え柱、又は各種架台の柱脚その他の部材が立設された基台が、貫通部材の上端面に連結されるか又は一体に設けられ、その基台下面が貫通部材の上方に配置されたシール受け面とされ、このシール受け面と貫通部材上端面との間の間隙に、シーリング材が充填されてなることを特徴とする。 In order to solve the above-described problem, the waterproof structure of the present invention is provided with a penetrating member such as a support penetrating through a waterproof sheet laid on the upper surface of the roof or floor, and in an exposed portion above the upper surface of the waterproof sheet. The outer peripheral surface of the penetrating member is covered with a cylindrical waterproof part, and the positioning part that prevents the cylindrical waterproof part from shifting downward is inward from the upper end of the peripheral wall of the cylindrical waterproof part. Protruding and mounted on the upper end surface of the penetrating member, mounting brackets for attaching antenna branch lines, etc., stand columns such as balconies, or bases on which column bases and other members of various mounts are erected It is connected to the upper end surface of the member or is integrally provided, and the lower surface of the base is a seal receiving surface disposed above the penetrating member, and in the gap between the seal receiving surface and the upper end surface of the penetrating member, that sealing material is filled And butterflies.
また、前記位置決め部は、筒状防水部上端より内向きにフランジ状に突出して形成されている。 Further, the positioning portion is formed to protrude in a flange shape inward from the upper end of the cylindrical waterproof portion.
さらに、前記筒状防水部の周壁下端より外方に向かって張り出すフランジ部の下面が、前記防水シートの上面に載置されている。 Furthermore, the lower surface of the flange portion projecting outward from the lower end of the peripheral wall of the cylindrical waterproof portion is placed on the upper surface of the waterproof sheet.
またさらに、前記筒状防水部は、前記防水シート上面より立ち上がる下側筒状防水部と、その下側筒状防水部の少なくとも上端部に外嵌される上側筒状防水部とからなっている。 Still further, the cylindrical waterproof part is composed of a lower cylindrical waterproof part that rises from the upper surface of the waterproof sheet, and an upper cylindrical waterproof part that is externally fitted to at least the upper end of the lower cylindrical waterproof part. .
さらに、前記上側筒状防水部と前記位置決め部とが一体に形成されている。またさらに、前記下側筒状防水部と前記フランジ部とが一体に形成されている。 Furthermore, the upper cylindrical waterproof part and the positioning part are integrally formed. Furthermore, the lower cylindrical waterproof part and the flange part are integrally formed.
この発明によれば、筒状防水部が下方へずれるのを防止する位置決め部が、貫通部材の上端面に載置されるため、筒状防水部が経年により収縮したとしても、その筒状防水部の上端を下方へずれないように一定の高さに保持できる。従って、筒状防水部の上端部に付着したシーリング材は、筒状防水部の収縮に伴って下方へ引っ張られる恐れがなく切れ目が発生しにくいため、シーリング施工の防水性能を高めることができる。しかも、ステンレス製のバンド等による筒状防水部上端の固定作業が必ずしも必要でなくなるため、施工性の向上、コストの低減化及び意匠性の向上を図ることができる。 According to this invention, since the positioning portion that prevents the cylindrical waterproof portion from shifting downward is placed on the upper end surface of the penetrating member, even if the cylindrical waterproof portion contracts over time, the cylindrical waterproof portion The upper end of the portion can be held at a constant height so as not to shift downward. Accordingly, the sealing material attached to the upper end portion of the cylindrical waterproof portion is not likely to be pulled down due to the shrinkage of the cylindrical waterproof portion, and it is difficult for a break to occur, so that the waterproof performance of the sealing work can be improved. In addition, it is not always necessary to fix the upper end of the cylindrical waterproof portion with a stainless steel band or the like, so that workability can be improved, costs can be reduced, and design can be improved.
また、シーリング材は、シール受け面と貫通部材上端面との間の間隙に充填されているため、十分なシーリング深さを確保することができる。それゆえ、シーリング材の切れ目がさらに生じにくくなるため、シーリング部分の防水性を一層高めることができる。 Further, since the sealing material is filled in the gap between the seal receiving surface and the penetrating member upper end surface, a sufficient sealing depth can be ensured. Therefore, since the cut of the sealing material is less likely to occur, the waterproofness of the sealing portion can be further enhanced.
さらに、筒状防水部が上下の筒状防水部により構成され、上側筒状防水部が下側筒状防水部の少なくとも上端部に外嵌されており、上側筒状防水部の下端部と下側筒状防水部の上端部とが重なった状態で、それら筒状防水部によって貫通部材の外周面が覆われているため、経年による収縮が生じたとしても、それら上下の筒状防水部間に隙間が生じることを防ぐことができ、貫通部材外周面を露出させることなく確実に覆うことができる。 Furthermore, the cylindrical waterproof part is composed of upper and lower cylindrical waterproof parts, and the upper cylindrical waterproof part is externally fitted to at least the upper end part of the lower cylindrical waterproof part. Since the outer peripheral surface of the penetrating member is covered with the cylindrical waterproof part in a state where the upper end of the side cylindrical waterproof part overlaps, even if shrinkage due to aging occurs, the space between the upper and lower cylindrical waterproof parts It is possible to prevent a gap from being formed in the cover, and to reliably cover the outer peripheral surface of the penetrating member without exposing it.
また、射出成形等により、上側筒状防水部と位置決め部とが一体に形成され、下側筒状防水部とフランジ部とが一体に形成されているため、現場での加工作業を省略して施工性を向上させることができるとともに、施工業者の技量に左右されることなく、簡単で確実な防水施工が可能となる。 In addition, the upper cylindrical waterproof part and the positioning part are integrally formed by injection molding, etc., and the lower cylindrical waterproof part and the flange part are integrally formed, so that the on-site processing work is omitted. Workability can be improved, and simple and reliable waterproof construction can be performed without being affected by the skill of the contractor.

これにより、防水シート(14)上面より上側の露出部分において、支柱本体(2)外周面は、上下の筒状防水部(26)(31)によって完全に覆われるようになっている。しかも、下側筒状防水部(26)の上端部と、上側筒状防水部(31)の下端部とが重なった状態で、それら筒状防水部(26)(31)が支柱本体(2)に外嵌している。従って、それら筒状防水部(26)(31)が経年によって収縮したとしても、上下の筒状防水部(26)(31)間に隙間が生じないため、支柱本体(2)外周面が露出しないようになっている。 Thereby, in the exposed part above the upper surface of the waterproof sheet (14), the outer peripheral surface of the column main body (2) is completely covered by the upper and lower cylindrical waterproof parts (26), (31). Moreover, in the state where the upper end portion of the lower cylindrical waterproof portion (26) and the lower end portion of the upper cylindrical waterproof portion (31) are overlapped, the cylindrical waterproof portions (26) and (31) are connected to the column main body (2 ). Therefore, even if these cylindrical waterproof parts (26) and (31) shrink due to aging, there is no gap between the upper and lower cylindrical waterproof parts (26) and (31), so the outer peripheral surface of the column main body (2) is exposed. It is supposed not to.
なお、上側筒状防水部(31)は、下側筒状防水部(26)の少なくとも上端部に外嵌されていれば良いので、下側筒状防水部(26)の全部若しくは大部分に外嵌されることを妨げるものではない。 Note that the upper cylindrical waterproof part (31) only needs to be externally fitted to at least the upper end of the lower cylindrical waterproof part (26), so that the lower cylindrical waterproof part (26) is entirely or largely attached. It does not prevent it from being externally fitted.
位置決め部(32)は、筒状防水部(31)上端より内向きにフランジ状に突出して形成されている。すなわち、位置決め部(32)の内側の先端には、例えば円形の開口部(33)が形成されており、この開口部(33)の内径は、支柱本体(2)上端部及び基台(4)の外径に比べてやや小径となっている。そして、設置状態において、位置決め部(32)は、支柱本体(2)の上端面に載置されており、筒状防水部(31)が下方へずれるのを防止できるようになっている。 The positioning portion (32) is formed so as to protrude in a flange shape inward from the upper end of the cylindrical waterproof portion (31). That is, for example, a circular opening (33) is formed at the inner end of the positioning part (32), and the inner diameter of the opening (33) is the upper end of the column main body (2) and the base (4). ) Is slightly smaller than the outer diameter. In the installed state, the positioning portion (32) is placed on the upper end surface of the column main body (2) so that the cylindrical waterproof portion (31) can be prevented from shifting downward.
シール受け面としての基台(4)下面と支柱本体(2)上面との間の間隙(35)には、シーリング材(36)が充填されている。 A sealing material (36) is filled in the gap (35) between the lower surface of the base (4) as the seal receiving surface and the upper surface of the column main body (2) .
このようにシーリング材(36)を充填できるような間隙(35)を形成することにより、十分なシーリング深さを確保することができ、シーリング材(36)に切れ目が発生しにくくなるため、防水性に優れたシーリング施工が可能となっている。 By forming the gap (35) so that the sealing material (36) can be filled in this way, a sufficient sealing depth can be secured, and it becomes difficult for the sealing material (36) to be cut. Sealing construction with excellent properties is possible.
以上の設置状態において、防水シート(14)上面より上側の露出部分における支柱本体(2)と、その支柱本体(2)が貫通する防水シート(14)の開口部(15)とは、上下の防水部材(25)(30)とシーリング材(36)によって完全に覆われることになり、支柱(1)貫通部の水密性が確保されるようになっている。しかも、位置決め部(32)の作用により、上側筒状防水部(31)が下方にずれることがなく、シーリング材(36)が下方に引っ張られる恐れがないため、シーリング材(36)に切れ目が入りにくくなっており、シーリング部分の防水性能が高まっている。 In the above installation state, the column main body (2) in the exposed portion above the upper surface of the waterproof sheet (14) and the opening (15) of the waterproof sheet (14) through which the column main body (2) passes are It is completely covered by the waterproof members (25), (30) and the sealing material (36), so that the water-tightness of the penetrating portion of the support column (1) is ensured. In addition, the upper cylindrical waterproof part (31) is not displaced downward due to the action of the positioning part (32), and there is no possibility of the sealing material (36) being pulled downward, so that the sealing material (36) is notched. It becomes difficult to enter, and the waterproof performance of the sealing part is increasing.
次に、支柱本体(2)貫通部の防水処理を施す手順について簡単に説明する。図2に示すように、防水シート(14)を貫通して設置された支柱本体(2)に対して、先ず、下側の防水部材(25)と上側の防水部材(30)を順次取り付ける。下側の防水部材(25)は、支柱本体(2)に筒状防水部(26)を外嵌させながら、フランジ部(27)下面を防水シート(14)上面に接着して取り付ける。続いて、支柱本体(2)に対して、その上側から上側防水部材(30)の筒状防水部(31)を外嵌させる。このとき、上側防水部材(30)は、その上端の位置決め部(32)の下面が基台(4)上面に引っ掛かってしまうが、そのまま弾性変形させながら下方へ押し込むと、位置決め部(32)と基台(4)との掛かりが外れて、図4に示すように、支柱本体(2)の上端面に位置決め部(32)が載置された状態となる。この状態において、基台(4)下面と支柱本体(2)上端面との間の間隙(35)に、図5に示すようにシーリング材(36)を充填することで、支柱本体(2)貫通部の防水処理が完了する。 Next, a procedure for waterproofing the column main body (2) through portion will be briefly described. As shown in FIG. 2, first, a lower waterproof member (25) and an upper waterproof member (30) are sequentially attached to the column main body (2) installed through the waterproof sheet (14). The lower waterproof member (25) is attached by adhering the lower surface of the flange portion (27) to the upper surface of the waterproof sheet (14) while fitting the cylindrical waterproof portion (26) to the support body (2). Subsequently, the cylindrical waterproof portion (31) of the upper waterproof member (30) is externally fitted to the column main body (2) from above. At this time, the upper waterproof member (30) has the lower surface of the positioning portion (32) at the upper end caught on the upper surface of the base (4). As shown in FIG. 4, the position of the positioning part (32) is placed on the upper end surface of the column main body (2). In this state, by filling the gap (35) between the lower surface of the base (4) and the upper end surface of the column body (2) with a sealing material (36) as shown in FIG. 5, the column body (2) The waterproofing process of the penetration part is completed.
ただし、上側防水部材(30)は、図3(a)に示すように、その周壁部の一箇所を軸方向に沿って切断してから施工するようにしても良い。この場合は、下側防水部材(25)が取り付けられた状態の支柱本体(2)に対して、上側防水部材(30)を巻き付けてその切断端部同士を接着等により接合することにより取り付ける。このように軸方向に沿った切れ目(37)を形成してから施工することにより、取付金具(5)若しくは基台(4)の大きさが、上側防水部材(30)上端の開口部(33)の内径よりも大きく、その開口部(33)内に取付金具(5)若しくは基台(4)を通すことが困難な場合でも、上側防水部材(30)の取付けが可能になる。 However, as shown in FIG. 3A, the upper waterproof member (30) may be constructed after cutting one portion of the peripheral wall portion along the axial direction. In this case, the upper waterproof member (30) is wound around the column main body (2) to which the lower waterproof member (25) is attached, and the cut ends are attached by bonding or the like. By forming the cut line (37) along the axial direction in this manner, the size of the mounting bracket (5) or the base (4) is changed to the opening (33) at the upper end of the upper waterproof member (30). The upper waterproof member (30) can be mounted even when it is difficult to pass the mounting bracket (5) or the base (4) through the opening (33).
他方、下側防水部材(25)についても、図3(b)に示すように、その周壁部の一箇所を軸方向に沿って切断してから施工するようにしても良い。この場合は、支柱本体(2)外周面に下側防水部材(25)を巻き付けて、その切断端部同士を補助部材(39)を介して接合することにより取り付ける。この補助部材(39)は、下側防水部材(25)全周のうちの一部と略同形状のものであり、下側防水部材(25)の切断端部間に跨って接着等により取り付けられる。この補助部材(39)を取り付けることにより、下側防水部材(25)における軸方向に沿った切れ目(38)部分の隙間が塞がれるようになっている。 On the other hand, as shown in FIG. 3 (b), the lower waterproof member (25) may be constructed after cutting one portion of the peripheral wall portion along the axial direction. In this case, the lower waterproof member (25) is wound around the outer peripheral surface of the column main body (2), and the cut ends are attached to each other via the auxiliary member (39). The auxiliary member (39) has substantially the same shape as a part of the entire circumference of the lower waterproof member (25), and is attached by bonding or the like across the cut end portion of the lower waterproof member (25). It is done. By attaching this auxiliary member (39), the gap of the cut (38) along the axial direction in the lower waterproof member (25) is closed.
このように、上下の防水部材(25)(30)の施工は、切れ目(37)(38)を設けずに上方から嵌め込むようにしても良いし、切れ目(37)(38)を設けておいてから巻き付けて接合するようにしても良い。なお、下側防水部材(25)は切れ目(38)を設けずに施工して、上側防水部材(30)についてのみ切れ目(37)を設けてから施工するようにしても良い。また、逆に下側防水部材(25)についてのみ切れ目(38)を設けてから施工するようにしたり、上下両方の防水部材(25)(30)ともに切れ目(37)(38)を設けてから施工するようにしても良いものとする。 Thus, the construction of the upper and lower waterproof members (25) and (30) may be fitted from above without providing the cut lines (37) and (38), or the cut lines (37) and (38) are provided. It may be wound around and joined. Note that the lower waterproof member (25) may be constructed without providing the cut (38), and the cut may be made after providing the cut (37) only for the upper waterproof member (30). On the other hand, it is necessary to construct the cut line (38) only for the lower waterproof member (25), or to install the cut lines (37) and (38) for both the upper and lower waterproof members (25) and (30). It may be constructed.
図6は、この発明に係るその他の実施形態を示している。この実施形態において、支柱本体(2)は、例えば屋上バルコニーにおける床の上面に敷設された防水シート(41)を貫通して設けられている。そして、上記の取付金具(5)に代えて、バルコニーの控え柱(40)が設けられている。この控え柱(40)は、基台(4)上に立設された例えば断面略ロ字形の鋼材からなっている。控え柱(40)下端面と基台(4)上面とは、例えば溶接により連結されている。 FIG. 6 shows another embodiment according to the present invention. In this embodiment, the column main body (2) is provided, for example, through a waterproof sheet (41) laid on the upper surface of the floor of a rooftop balcony. Then, instead of the mounting bracket (5), a balcony post (40) is provided. The retaining column (40) is made of, for example, a steel material having a substantially square-shaped cross section standing on the base (4). The lower end surface of the column (40) and the upper surface of the base (4) are connected by, for example, welding.
