【発明の詳細な説明】 産業上の利用分野 本発明は、家屋、コンクリート造の建物等の屋根、特
に屋上等の陸屋根の防水工事に有効に利用できる脱気用
部材に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deaeration member that can be effectively used for waterproofing roofs of houses, concrete buildings, and the like, particularly, roofs and other roofs.
従来の技術 近年、家屋やコンクリート造の建物における陸屋根等
の露出部分には内部への水の透過、浸透を防止するため
に、防水処理として、アスファルトによる防水、プラス
チック等のシートによる防水、或いは塗膜による防水な
どの処理が一般的に行われている。2. Description of the Related Art In recent years, in order to prevent the penetration and penetration of water into the interior of houses and concrete roofs, exposed portions such as flat roofs have recently been subjected to waterproofing treatment with asphalt, waterproofing with a sheet of plastic or the like, or coating. Processing such as waterproofing with a membrane is generally performed.
発明が解決しようとする問題点 しかしながら、このような防水処理を行うと、漏水問
題とは別に、初めに打設したコンクリート層中に含まれ
ている水分が太陽熱により暖められて蒸気化し、防水処
理層を蒸気圧によって徐々に押し上げる「ふくれ上が
り」の現象が大きな問題点として指摘されている。Problems to be Solved by the Invention However, when such a waterproofing treatment is performed, separately from the water leakage problem, the moisture contained in the concrete layer initially cast is heated by the solar heat and vaporized, and the waterproofing treatment is performed. The phenomenon of "bulging", in which the bed is gradually pushed up by the vapor pressure, has been pointed out as a major problem.
このため、このふくれ上がり現象を防止するために種
々の脱気装置が提案されているが、これらの脱気装置を
利用するときは、完成された防水処理層を切開して設置
するため、工事が繁雑であると共に、切開部分を防水処
理するのに問題がある。また、脱気装置を設置する部分
を予め切開した場合は、やはり当該部分の防水処理にか
なりの手間を要するものであった。For this reason, various deaerators have been proposed to prevent this bulging phenomenon. However, when these deaerators are used, it is necessary to cut out and install the completed waterproofing layer. Is complicated and there is a problem in waterproofing the incision. In addition, when the portion where the deaerator is to be installed is previously incised, the waterproofing of the portion also requires considerable labor.
また、この防水層の上に更にコンクリートを打設して
防水処理をより安全に行う方法もあるが、この場合は、
初めに打設したコンクリート層に残存した水分は外部へ
脱出できず、建物の内部へ入り込むようになり、建物の
内部にかびが生じる原因ともなっていた。In addition, there is a method in which concrete is further poured on the waterproof layer to perform a waterproof treatment more safely. In this case,
Moisture remaining in the concrete layer that was initially cast cannot escape to the outside, but instead enters the interior of the building, causing mold inside the building.
従って、陸屋根部分においては、コンクリートに残存
する水分を外部に蒸散させるための部材の開発が急がれ
ていた。Therefore, in the flat roof portion, the development of a member for evaporating the moisture remaining in the concrete to the outside has been urgent.
本発明は、かかる事情に鑑みなされたもので、防水シ

コンクリート内部に残存した水分を外部に効果的に逸散
し、しかも水分の蒸散が終了したあとは、雨水等が防水
シート等の下に打設されたコンクリート内部へ逆に侵入
して、防水処理効果を無くさないように密閉状態に維持
できる脱気用部材を提供することを目的とするものであ
る。The present invention has been made in view of such circumstances, and effectively disperses moisture remaining in the concrete of a concrete flat roof portion waterproofed with a waterproof sheet or the like to the outside, and after the evaporation of moisture has been completed. It is an object of the present invention to provide a deaeration member that can maintain a sealed state so that rainwater or the like invades the inside of concrete placed under a waterproof sheet or the like in reverse and does not lose the waterproofing effect. is there.
問題点を解決するための手段 本発明は、上記の目的を達成するために、防水シート

を閉塞するようにそれぞれ配設したものである。Means for Solving the Problems In order to achieve the above object, the present invention provides a degassing member that is attached to cover a vent formed in advance on a waterproof sheet or the like, and has a breathable member inside a cylindrical frame. A membrane and a sealing body having a through-hole formed by a hot-melt resin and evaporating moisture in the concrete to the outside, and then closed by the hot-melted resin, to form a hollow portion in the frame body. Are arranged so as to close each other.
この場合、通気性膜と封止体とを互に離間して配設す

を覆って透孔を有する蓋体を被着させることが、水蒸気
の蒸発逸散中において、雨水が防水層を通ってコンクリ
ート内部もしくは建物内部に侵入することがより確実に
防止されるので好ましい。In this case, it is preferable to dispose the air-permeable membrane and the sealing member apart from each other, and to attach a lid having a through hole to cover the opening of the frame on the sealing member disposing side. This is preferable because rainwater is more reliably prevented from penetrating into concrete or a building through the waterproof layer during the evaporation and dissipation of water vapor.

このためコンクリートより発生した水蒸気によって防水
処理層の「ふくれ上がり」現象が生じることを確実に防
止することができる。The degassing member of the present invention is mounted on a waterproof sheet or the like in advance so as to cover a ventilation hole provided for dissipating water vapor. If constructed as a waterproof treatment layer of the part,
Even if the moisture remaining in the concrete below the treatment layer is warmed by solar heat or the like, this water vapor passes through the ventilation holes of the waterproof sheet or the like and enters the hollow portion of the deaeration member of the present invention to form a permeable membrane. Then, it is radiated to the outside through the through-hole of the sealing body and further through the through-hole of the lid when the lid is attached.
For this reason, it is possible to reliably prevent the "bulging" phenomenon of the waterproof treatment layer from being caused by the water vapor generated from the concrete.
また、前述のコンクリートからの水蒸気の発生が終了

ので、防水シート等に通気孔が形成されたままであって
も、防水層が密閉された状態となり、かつこの密閉状態
が維持されるので、雨水等の水分の建物内部への漏水を
確実に防止することができる。Further, after the generation of water vapor from the above-mentioned concrete is completed and the escape of the water vapor is no longer recognized, the heat-meltable resin disposed as a sealing body in the member is heated and melted to form the pre-formed resin. The through hole is closed to prevent rainwater or the like from entering from outside. When the through hole is closed, the molten resin may be supplied as needed. As a result, the sealing member completely closes the hollow portion of this member and blocks the evaporation of water vapor and the inflow of moisture from the outside, so that even if the ventilation holes are still formed in the waterproof sheet or the like, the waterproof layer Is sealed, and this sealed state is maintained, so that leakage of moisture such as rainwater into the building can be reliably prevented.

The lid 9 is removed, and the sealing body 6 is heated to melt the hot-melt resin, thereby closing the through hole 8 of the sealing body 6.
Then, if necessary, the lid 9 is attached again, and if necessary, concrete is cast on a waterproof sheet or a waterproof layer. Therefore, the hollow portion 3a of the frame 3 is completely airtightly closed by closing the through hole 8, and even if the ventilation holes 12 are still formed in the waterproof sheet or the waterproof layer, they remain in a sealed state. Is maintained, and the waterproof function is effectively exhibited.
