Description

本発明は、工場等建築物に採用される折板屋根、デッキプレートなどの金属下地或いは木質下地等の軽量化が要求される建築物の屋根上に断熱材を付設する外断熱防水構造に関するものである。   TECHNICAL FIELD The present invention relates to an outer heat insulating waterproof structure in which a heat insulating material is attached on a roof of a building that is required to be light weight such as a metal base such as a folded roof, a deck plate, or a wooden base used in a building such as a factory. It is.

近年、わが国沿岸部や市街地において異常気象による台風、竜巻、突風やゲリラ豪雨が発生し被害も多発している。これらの気象現象により、倉庫、店舗、工場等鉄骨造りの建築物の倒壊や屋根の飛散など被害が発生している。
金属下地屋根への機械的固定法によるシート防水絶縁工法では、施工後３年も経たないうちに防水シートの飛散や漏水事故が多発している。これは、強風を繰り返し受けることにより起こる防水シートのフラッタリング等の影響で防水シート固定具（固定ディスクなど）の湾曲、ビスの緩み（逆ねじ現象）、ビスの破損、さらにそれらにより防水シートに破損が発生し防水シートの飛散や漏水事故に繋がると考えられている。フラッタリング現象は防水シートを接着剤で下地に固定すれば防止できるが、接着工法は施工時の気象条件に影響を受けやすく機械的固定法に比べ工期が大幅に延びてしまい、施工面積が広い大きな現場では採用しにくい工法である。 In recent years, typhoons, tornadoes, gusts and guerrilla heavy rain due to abnormal weather have occurred in coastal areas and urban areas of Japan, causing frequent damage. Due to these meteorological phenomena, damages such as collapse of steel-framed buildings such as warehouses, stores, factories and scattering of roofs have occurred.
In the sheet waterproof insulation method by the mechanical fixing method to the metal base roof, the scattering of the waterproof sheet and the water leakage accident occur frequently within 3 years after the construction. This is because of the effects of fluttering of the waterproof sheet caused by repeated strong winds, bending of the waterproof sheet fixing tool (fixing disk, etc.), loosening of the screw (reverse screw phenomenon), damage to the screw, and further to the waterproof sheet It is thought that damage will occur, leading to splashing of waterproof sheets and water leakage accidents. The fluttering phenomenon can be prevented by fixing the waterproof sheet to the base with an adhesive, but the bonding method is easily affected by the weather conditions during construction, and the construction period is significantly longer than the mechanical fixing method, resulting in a large construction area. This method is difficult to adopt at large sites.

また、金属下地屋根構造の工場などは夏場に屋内の気温上昇が著しく、この対策として金属下地屋根の上に断熱材を取り付ける外断熱屋根構造が検討されている。例えば、特許文献１には折板屋根の改修構造が記載されており、折板屋根と改修用断熱パネルの間に接着剤層を設けるもので、折板屋根の重なり部分での改修用断熱パネル端部の浮き上がりを接着剤層が緩衝することにより防止でき、改修用断熱パネルを折板屋根にタッピングビスでビス止めしても接着剤がビス穴の隙間を充填するため漏水が防止できるというものである。この構造によれば、雨水は接着剤層で止まり折板屋根の下には漏水しないが、改修用断熱パネルの塩ビ鋼板などの防水処理層と断熱材などのパネル本体の間に雨水が浸透し、防水処理層とパネル本体の剥離や劣化を促進する恐れがある。   In addition, the temperature of indoors is extremely high in summer in factories with metal base roof structures, and an external heat insulating roof structure in which a heat insulating material is attached on the metal base roof has been studied as a countermeasure. For example, Patent Document 1 describes a structure for repairing a folded-plate roof, in which an adhesive layer is provided between the folded-plate roof and the heat-insulating panel for repair. It can be prevented by the adhesive layer buffering the lifting of the edge, and even if the heat insulation panel for repair is screwed to the folded plate roof with a tapping screw, the adhesive fills the gap of the screw hole and can prevent water leakage It is. According to this structure, rainwater stops at the adhesive layer and does not leak under the folded roof, but rainwater permeates between the waterproof treatment layer such as PVC steel plate of the insulation panel for repair and the panel body such as insulation. There is a risk of promoting peeling and deterioration of the waterproof layer and the panel body.

特許文献２には断熱材と防水材を積層したパネルを屋根下地上に敷設し、繋ぎ目防水シートで貼着する防水構造が記載されている。この構造は断熱材の上下面に金属板を積層一体化しており、工期を短縮して歩行も可能となるが、断熱材に金属板を積層一体化しているため重量があり、少人数での作業を考えるとパネルの大型化が困難となる。   Patent Document 2 describes a waterproof structure in which a panel in which a heat insulating material and a waterproof material are laminated is laid on a roof base and adhered with a joint waterproof sheet. In this structure, metal plates are laminated and integrated on the upper and lower surfaces of the heat insulating material, and it is possible to walk by shortening the work period, but because the metal plates are integrated and integrated with the heat insulating material, there is weight, and a small number of people Considering the work, it becomes difficult to enlarge the panel.

There is no fluttering of the waterproof sheet, the water-tightness is excellent, and the panel is easy to reuse.

本発明では、防水パネルを合成樹脂製発泡体と熱可塑性樹脂製防水シートとを粘着材Ａにより積層一体化したためフラッタリング現象は起きず、粘着材Ａが上記積層面全面にシームレスに貼着した２重防水構造となっているため、落下物等で熱可塑性樹脂製防水シートが傷ついたとしても直ちに漏水の危険はなくなる。
また、長尺の押え金属板のビス止め部は、長尺の押え金属板が長尺の熱可塑性樹脂製長辺用役物で覆われ熱可塑性樹脂製防水シートに溶着され防水性が確保されている上、長尺の押え金属板の下面には粘着材Ｂが存在し熱可塑性樹脂製防水シートを貫通するビスと熱可塑性樹脂製防水シート間を止水しており、押え金具のビス止め部も、押え金具が熱可塑性樹脂製増し張り役物で覆われ熱可塑性樹脂製防水シートに溶着され防水性が確保されている上、押え金具下面には粘着材Ｃが存在し熱可塑性樹脂製防水シートを貫通するビスと熱可塑性樹脂製防水シート間を止水している。このように防水シートをビスが貫通する部分は、防水シートと上記２種の役物を溶着することにより水密状となり、加えて粘着材Ｂ、Ｃにより止水できる２重の防水構造を形成しているため防水の信頼度が高くなる。
また、屋根が金属下地の場合、ビス止め部では粘着材Ｂ、Ｃが存在し空気が還流しないため金属下地、長尺の押え金属板、押え金具には結露も発生せずサビも防止でき、工場等の建屋で振動がある場合でも、ビスは長尺の押え金属板又は押え金具と金属下地屋根の２箇所の金属板にビス掛かかりした上、粘着材Ａと粘着材Ｂ、Ｃのどちらかの２箇所を貫通するためこの粘着材層が緩衝しビスの逆ねじ現象は起きない。
また、本発明の防水パネルは金属板を積層していないため、パネル取り扱い中にパネル端部で手に切り傷などを負うことなく安全に作業することができる。
また、本発明で粘着材ＢとＣに後述する片面粘着テープを用い防水シートにのみ粘着させ、長尺の押え金属板と押え金具には粘着させない構成をとることにより、長尺の熱可塑性樹脂製長辺用役物、後述する防水パネル短辺端縁突き付け部分の防水処理部、熱可塑性樹脂製増し張り役物をカッター等で切って取り除き、押え金具と長尺の押え金属板からビスを緩めて取り外せば、防水パネルをそれぞれ屋根から容易に取り外すことができ、防水パネルの再利用が可能となる。 In the present invention, since the waterproof panel is laminated and integrated with the synthetic resin foam and the thermoplastic resin waterproof sheet with the adhesive material A, the fluttering phenomenon does not occur, and the adhesive material A seamlessly adheres to the entire surface of the laminate. The double waterproof structure eliminates the risk of water leakage even if the thermoplastic waterproof sheet is damaged by falling objects.
In addition, the screw holding part of the long presser metal plate has a long presser metal plate covered with a long thermoplastic resin long-side accessory and welded to a thermoplastic resin waterproof sheet to ensure waterproofness. In addition, adhesive B is present on the lower surface of the long presser metal plate, and water is sealed between the screw that penetrates the thermoplastic resin tarpaulin and the thermoplastic resin tarpaulin. The presser fitting is also covered with an additional thermoplastic resin tension member and welded to a thermoplastic resin waterproof sheet to ensure waterproofness. Adhesive C is present on the bottom of the presser fitting and is made of thermoplastic resin. Water is stopped between the screw penetrating the waterproof sheet and the thermoplastic resin waterproof sheet. In this way, the portion where the screw penetrates the waterproof sheet becomes watertight by welding the waterproof sheet and the above two types of objects, and in addition, forms a double waterproof structure that can be stopped by the adhesive materials B and C. This increases the reliability of waterproofing.
In addition, when the roof is a metal base, adhesive materials B and C are present at the screw stop and air does not recirculate, so no condensation occurs on the metal base, long presser metal plate, presser fitting, and rust can be prevented. Even if there is vibration in a building such as a factory, the screw is attached to two metal plates, a long presser metal plate or presser fitting and a metal base roof, and either adhesive material A or adhesive material B, C The adhesive material layer is buffered because it penetrates these two places, and the reverse screw phenomenon of the screw does not occur.
Moreover, since the waterproof panel of this invention does not laminate | stack a metal plate, it can operate | work safely, without incurring cuts etc. to a hand at the panel edge part during panel handling.
Further, in the present invention, a long thermoplastic resin is formed by adhering only to the waterproof sheet using the single-sided adhesive tape described later on the adhesive materials B and C and not adhering to the long presser metal plate and the presser fitting. Use a cutter to remove the long-sided accessory, waterproofing part at the edge of the short edge of the waterproof panel, which will be described later, and thermoplastic resin, and remove the screw from the presser bracket and the long presser metal plate. If they are loosened and removed, the waterproof panels can be easily removed from the roof, and the waterproof panels can be reused.

さらに、粘着材Ａを止水性の高いアクリル系粘着材又はブチル系粘着材とすることにより、安価で作業性がよく合成樹脂製発泡体と熱可塑性樹脂製防水シートとを積層一体化することができる。粘着材Ｂ、Ｃを止水性の高いアクリル系粘着材又はブチル系粘着材とすることにより、長尺の押え金属板、押え金具のビス止め部の止水性が高まり、結露防止効果も増大する。   Furthermore, by making the adhesive material A an acrylic adhesive material or butyl adhesive material with high water-stopping properties, a synthetic resin foam and a thermoplastic resin waterproof sheet can be laminated and integrated at low cost and with good workability. it can. By making the adhesive materials B and C into acrylic adhesive materials or butyl adhesive materials having high water-stopping properties, the water-stopping properties of the screw holding portions of long presser metal plates and presser fittings are increased, and the effect of preventing condensation is also increased.

加えて、本発明の構成とすることにより、軽量となり防水パネルの大型化が可能となって長辺１２０００ｍｍの防水パネルも使用することできるようになる。   In addition, by adopting the configuration of the present invention, the waterproof panel can be made lighter and the waterproof panel can be enlarged, and a waterproof panel having a long side of 12000 mm can be used.
