Description

コンクリート系防水下地のシート防水工法において、床仕上げ板（本発明では複合パネルに該当する）を防水シート上に浮かして施工する浮き床構造に関する。   The present invention relates to a floating floor structure in which a floor finish plate (corresponding to a composite panel in the present invention) is floated and constructed on a waterproof sheet in a concrete waterproof base sheet waterproofing method.

従来、ビルの屋上はアスファルト防水の上に、コンクリートを流し込んだシンダー押さえ工法が主流であったが、近年の石油価格高騰と環境問題から、アスファルト防水シンダー押さえ工法が敬遠されつつあり、それに変わる塩ビシート防水シンダー押さえ工法が増える方向にある。また、最近では防水層の上に保護層としてのコンクリートを打設しない乾式の押さえ工法、浮き床工法などが提案されている。   Conventionally, the cinder pressing method that poured concrete into the rooftop of asphalt waterproofing has been the mainstream. Bi-sheet waterproof cinder holding method is increasing. Recently, dry pressing methods and floating floor methods that do not place concrete as a protective layer on the waterproof layer have been proposed.

一般に、シート防水工事ではコンクリート系防水下地に防水シートを接着剤により接着固定、或いは固定金具を用いて機械的固定した後、隣り合った防水シート同士を接合して防水シートが施工される。上記乾式の押え工法は、施工された防水シート上に、１〜５ｍｍ厚みの発泡ポリエチレンシート、ポリエステル繊維やポリプロピレン繊維系の不織布、ポリエチレンを発泡させた格子状ネット等の緩衝材を敷設後、その上に、コンクリート系成形品、セラミック系焼成品、木質系品等の化粧兼歩行保護用床仕上げ板を、複数枚敷き並べていくものである。この乾式の押え工法で、防水シートを機械的固定する場合は、その固定金具の位置に上記床仕上げ板が載ると、段差によりガタツキが生じその調整をするために過大な手間が掛かり、さらに歩行等により床仕上げ板が損傷するなどの問題点も生じる。また、防水シートを機械的固定する押え工法では、下地の不陸を拾いやすく仕上がり状態も好ましいものではないという問題点がある。   In general, in a sheet waterproofing work, a waterproof sheet is bonded and fixed to a concrete waterproof base with an adhesive or mechanically fixed using a fixing bracket, and then the adjacent waterproof sheets are joined together to install the waterproof sheet. The above-mentioned dry-type presser method is constructed by laying a cushioning material such as a foamed polyethylene sheet having a thickness of 1 to 5 mm, a polyester fiber or polypropylene fiber-based nonwoven fabric, or a lattice net made by foaming polyethylene on a constructed waterproof sheet. A plurality of floor finish plates for makeup and walking protection such as concrete-based molded products, ceramic-based fired products, and wood-based products are laid on top of each other. When mechanically fixing a waterproof sheet with this dry-type presser method, if the floor finish plate is placed at the position of the fixing bracket, a rattling will occur due to a step, and it will take excessive labor to adjust it, and further walking The problem that a floor finish board is damaged by etc. also arises. In addition, the presser method for mechanically fixing the waterproof sheet has a problem that it is easy to pick up unevenness of the ground and the finished state is not preferable.

上記浮き床工法は、上述のように施工した防水シート上の所定位置に床仕上げ板設置用の高さ調整付き支持架台を載置或いは固定し、その支持架台に床仕上げ板を固定するものである。図５の如く支持架台は防水シート上に碁盤目のように配置され、１つの支持架台には４つの床仕上げ板の隅が載り、床仕上げ板の４隅がすべて別の支持架台に載るようにする。この浮き床工法では、表面はフラットとなり上述の押え工法に比べてきれいに仕上がるが、この工法は押え工法と比べると、防水シートを防水下地に施工して、それから支持架台を防水下地に固定し、さらに床仕上げ板を支持架台に固定するため、使用する部材、施工の工数が増えてコスト的に割高に成ってしまうという欠点があり、さらに、床仕上げ板面での防水は考慮されておらず、降雨時には防水シート面まで雨水が入ってくるため、防水シートと床仕上げ板との空間は高湿の状態になり易く、防水シートの劣化、支持架台等部材のサビや劣化が懸念され耐久性に課題が残る。   The floating floor construction method is to place or fix a support frame with height adjustment for floor finishing plate installation at a predetermined position on the waterproof sheet constructed as described above, and fix the floor finishing plate to the support frame. is there. As shown in FIG. 5, the support base is arranged like a grid on the waterproof sheet, and one support base has four corners of the floor finish plate, and all four corners of the floor finish plate rest on another support base. To. In this floating floor construction method, the surface is flat and finished more beautifully than the above-mentioned presser method, but compared to the presser method, this method applies the waterproof sheet to the waterproof base, and then fixes the support base to the waterproof base, Furthermore, because the floor finish plate is fixed to the support base, there is a disadvantage that the number of members used and the number of man-hours for construction increase, resulting in higher costs, and waterproofing on the floor finish plate surface is not considered. When raining, rainwater enters the surface of the tarpaulin, so the space between the tarpaulin and the floor finish plate is likely to be in a highly humid state, and there is concern about deterioration of the tarpaulin and rusting and deterioration of members such as the support frame. The problem remains.

浮き床工法では、床仕上げ板の固定部が仕上げ板の上面を突出しない固定工法（特許文献１）、防水シートに穴を開けずに支持部材を固定する方法（特許文献２）が提案されている。特許文献１の方法は床仕上げ板の側面に溝を設け、この溝に固定部を収納して固定部が仕上げ板の上面を突出しないようにしたものであり、特許文献２の方法は支持架台の下面に接合部材を設け、下地に施工された防水シートにこの接合部材を溶着して防水シートに孔を開けることなく支持架台を下地に固定する方法である。上述したような浮き床工法の問題点、すなわち使用する部材の削減、施工工数の低減、雨水による防水シートの劣化、支持架台等部材のサビや劣化については検討されておらず、開発が望まれている。
特開２００１−１７３２０４号公報 特開２００４−２８５６１４号公報 In the floating floor method, there are proposed a fixing method (Patent Document 1) in which the fixing portion of the floor finish plate does not protrude from the upper surface of the finish plate, and a method of fixing the support member without making a hole in the waterproof sheet (Patent Document 2). Yes. In the method of Patent Literature 1, a groove is provided on the side surface of the floor finish plate, and a fixing portion is accommodated in the groove so that the fixing portion does not protrude from the upper surface of the finishing plate. In this method, a joining member is provided on the lower surface of the sheet, and the joining member is welded to a waterproof sheet applied to the base, and the support frame is fixed to the base without opening a hole in the waterproof sheet. The problems with the floating floor construction method as described above, ie, reduction of members to be used, reduction of construction man-hours, deterioration of waterproof sheets due to rainwater, rust and deterioration of members such as support frames, etc. have not been studied and development is desired. ing.

In order to achieve such an object, the means taken by the present invention is to lay a thermoplastic resin waterproof sheet on a waterproof base, arrange a support frame at a predetermined position on the thermoplastic resin waterproof sheet ,
The support frame is composed of a pedestal and a bolt part erected from the pedestal, and the pedestal and the lower part of the bolt part are covered with a thermoplastic resin, and a pedestal fixing screw penetrates the support frame and the thermoplastic resin waterproof sheet, and is waterproof. by being fixed to, and fixed to said support cradle and tarpaulin made thermoplastic resin waterproof foundation,
Covering the pedestal of the support frame with an additional tension sheet, and welding the additional tension sheet, the thermoplastic resin waterproof sheet and the pedestal of the support frame;
A panel holder having a female threaded portion inside is screwed into the bolt part of the support frame, and a composite panel having a welded resin layer on the surface is fixed to the panel holder,
The floating floor construction method is characterized by waterproofing between the adjacent composite panels (Claim 1).
Lay out a thermoplastic resin tarpaulin on a waterproof base, place a support base at a predetermined position on the thermoplastic resin tarpaulin ,
The support frame is composed of a pedestal and a bolt part erected from the pedestal, and the pedestal and the lower part of the bolt part are covered with a thermoplastic resin, and a pedestal fixing screw penetrates the support frame and the thermoplastic resin waterproof sheet, and is waterproof. by being fixed to, and fixed to said support cradle and tarpaulin made thermoplastic resin waterproof foundation,
Covering the pedestal of the support frame with an additional tension sheet, and welding the additional tension sheet, the thermoplastic resin waterproof sheet and the pedestal of the support frame;
A panel long receiver is fixed to a plurality of bolts of the support frame, a composite panel having a welded resin layer on the surface is fixed to the panel long receiver, and a waterproof treatment is performed between adjacent composite panels. This is a floating floor construction method characterized in that (claim 2).

本発明によれば、従来のように防水シートを下地に接着剤、固定金具などで固定してから、支持架台を下地に固定する２工程は必要なく、１工程で済む。すなわち、支持架台の台座で防水シートを固定するので、防水シートと支持架台の下地への固定を１工程で同時に行うことができ、部材の削減、工数の低減が図れる。また、支持架台の台座とボルト部下部が熱可塑性樹脂で被覆されているため、増し張りシートで支持架台の台座及び防水シートとに加熱溶着または溶剤溶着することができ、その接合は強化され、防水性が充分に確保できる。加えて、隣り合う複合パネルの間を防水処理することにより、防水シート面での防水、複合パネル表面での防水と防水構造を２重にし、雨水による防水シートの劣化、支持架台等部材のサビや劣化を防止し防水性を長期間確保することができる。
さらに、複数の支持架台とパネル用長尺受け具が連結する形態においては、浮き床構造の局所に風圧などの負圧がかかったとしても、複数の支持架台がパネル用長尺受け具により連結しているため、負圧は複数の支持架台に分散されるので、防水下地への支持架台固定の信頼性が高まる。また、パネル用の受け具が長尺であるため、複合パネルはパネル用長尺受け具のどの位置にも固定できて支持架台部分で固定する必要はなくなり、施工が容易にできるようになる。 According to the present invention, there is no need for the two steps of fixing the waterproof sheet to the base and fixing the support frame to the base after fixing the waterproof sheet to the base with a conventional method. That is, since the waterproof sheet is fixed on the pedestal of the support frame, the waterproof sheet and the support frame can be fixed to the base simultaneously in one process, and the number of members and man-hours can be reduced. In addition, since the base of the support base and the lower part of the bolt part are coated with the thermoplastic resin, it can be heat-welded or solvent-welded to the base of the support base and the waterproof sheet with the additional tension sheet, and the bonding is strengthened, Sufficient waterproofness can be secured. In addition, by waterproofing between adjacent composite panels, waterproofing on the surface of the waterproof sheet, double waterproofing and waterproof structure on the surface of the composite panel, deterioration of the waterproof sheet due to rainwater, It is possible to prevent waterproofing and ensure waterproofness for a long time.
Furthermore, in the form in which a plurality of support bases and long panel supports are connected, even if negative pressure such as wind pressure is applied locally to the floating floor structure, the plurality of support bases are connected by a long panel support. Therefore, since the negative pressure is distributed to the plurality of support frames, the reliability of fixing the support frame to the waterproof base is increased. In addition, since the panel support is long, the composite panel can be fixed at any position of the panel long support and does not need to be fixed at the support frame portion, so that the construction can be facilitated.

Embodiment 1 is shown in FIG.
In this floating floor structure, a thermoplastic waterproof sheet 2 is laid on a concrete waterproof base 1, and a predetermined position on the thermoplastic resin waterproof sheet 2 is provided between the base 31 and the thermoplastic waterproof sheet 2. In the state where the adhesive tape 4 is bonded, the support base 3 composed of the base 31 and the bolt portion 32 erected from the base through the thermoplastic resin waterproof sheet 2 is fixed to the waterproof base 1 by the base fixing screw 312. ,
As shown in FIG. 8, the additional tension sheet 5 having a hole 51 larger than the outer diameter of the bolt portion 32 is placed at substantially the center so as to cover the pedestal 31 through the bolt portion 32 in the hole 51, and the additional tension sheet 5 is placed on the pedestal 31. And thermoplastic resin tarpaulin 2 by heat welding, solvent welding, etc.
The female screw of the nut part 62 of the panel holder 6 is screwed into the bolt part 32 of the support frame 3, the height of the panel holder 6 is adjusted, and the composite panel 7 is placed on the receiving part 61 of the panel holder 6, The panel fixing screw 63 fixes the composite panel 8 having the welded resin layer 81 on the surface to the panel holder 6,
After affixing a buffer joint tape 91 having a width narrower than that of the stretched waterproof sheet 9 to the butt joints of adjacent composite panels 8, the stretched waterproof sheet 9 and the composite panel 8 are welded together to be waterproofed. It is the structure which processed.
As shown in FIG. 5, a required number of support frames 3 are placed on a thermoplastic resin waterproof sheet 2 at a required position in a grid pattern, and fixed to the waterproof base 1. In FIG. 5, the vertical and horizontal intervals of the support frame 3 are the same, but the vertical and horizontal intervals are set differently so that the composite panel 8 can correspond to a rectangular shape. Also good. The composite panel 8 is fixed at four corners by four support frames 3, and one corner of the four composite panels 8 is fixed to one support frame 3.

上記熱可塑性樹脂製防水シート２としては、塩化ビニル樹脂系防水シート、オレフィン樹脂系防水シート、アクリル樹脂系防水シート等が使用できる。塩化ビニル樹脂系防水シートが、施工性、シート同士の溶着性、防水シート固定金具との密着性の点から好ましい。熱可塑性樹脂製防水シートの厚さとしては、０．５〜５．０ｍｍのものが使用でき、１．０〜２．５ｍｍが好ましい。   As the thermoplastic resin waterproof sheet 2, a vinyl chloride resin waterproof sheet, an olefin resin waterproof sheet, an acrylic resin waterproof sheet, or the like can be used. A vinyl chloride resin-based waterproof sheet is preferable from the viewpoint of workability, weldability between sheets, and adhesiveness to the waterproof sheet fixing bracket. The thickness of the thermoplastic resin waterproof sheet can be 0.5 to 5.0 mm, preferably 1.0 to 2.5 mm.

上記支持架台３は図８に示すように、台座３１及び台座３１から立設したボルト部３２からなり、台座３１には防水下地に固定するためのビス穴３１１を複数個設けてある。台座３１とボルト部３２は接着剤、溶接等で簡単に一体化することができるが、台座３１にネジ切りしボルト部３２を螺合してから溶接すると強度が向上する。
支持架台３の材質としては、金属、高強度の熱可塑性樹脂、熱硬化性樹脂などが使用でき、強度面からは金属がよく、中でも鋼材が良い。鋼材を使用する場合、ボルト部３２の径は５〜３０ｍｍがよく、強度とコストを考慮すると１０〜２０ｍｍがより好ましい。ボルト部３２の長さは５０〜１００ｍｍのものが使用される。台座３１の厚さは、鋼材を使用する場合、１．０〜１０ｍｍがよく、強度とコストを考慮すると１．６〜６．０ｍｍがより好ましく、２．０〜４．０ｍｍがさらに好ましい。台座３１の外径は５０〜１５０ｍｍのものが使用される。台座３１の外径が５０ｍｍより小さいと支持架台３の収まりが不安定となり、１５０ｍｍを越えると溶着の手間が掛かり強度的にも飽和し意味が無くなる。
被覆樹脂層３３として、支持架台３及びボルト部３２下部の５〜１０ｍｍ部分を熱可塑性樹脂で被覆する必要があり、被覆樹脂層３３の厚みは０．１〜３ｍｍがよい。被覆する熱可塑性樹脂は、増し張りシート５、熱可塑性樹脂製防水シート２と同質または同種の溶着しやすい樹脂がよく塩化ビニル系樹脂、オレフィン系樹脂、アクリル系樹脂が好ましい。台座３１は図８には円形のものを示すが、円形に限定されるものではなく多角形その他の形状でも構わない。
架台固定ビス３１２により熱可塑性樹脂製防水シート２を貫通して支持架台３を防水下地１に固定する際、必ずしも必要とするものではないが図１に示すごとく台座３１と熱可塑性樹脂製防水シート２との間に粘着テープ４を貼り合わせることがよく、このことにより防水性が一段と向上する。粘着テープ４としては、ブチル系、アクリル系、エチレン−酢酸ビニル共重合樹脂（ＥＶＡ）系などの片面又は両面粘着テープがあるが、防水性の点ではブチル系両面粘着テープが好ましい。 As shown in FIG. 8, the support frame 3 includes a pedestal 31 and a bolt portion 32 erected from the pedestal 31, and the pedestal 31 is provided with a plurality of screw holes 311 for fixing to a waterproof base. The pedestal 31 and the bolt part 32 can be easily integrated by an adhesive, welding or the like, but the strength is improved by screwing the pedestal 31 and screwing the bolt part 32 before welding.
As a material of the support frame 3, a metal, a high-strength thermoplastic resin, a thermosetting resin, or the like can be used. A metal is preferable in terms of strength, and a steel material is particularly preferable. In the case of using a steel material, the diameter of the bolt portion 32 is preferably 5 to 30 mm, and more preferably 10 to 20 mm in consideration of strength and cost. The bolt part 32 has a length of 50 to 100 mm. When steel is used, the thickness of the pedestal 31 is preferably 1.0 to 10 mm, more preferably 1.6 to 6.0 mm, and even more preferably 2.0 to 4.0 mm in consideration of strength and cost. The outer diameter of the base 31 is 50 to 150 mm. If the outer diameter of the pedestal 31 is smaller than 50 mm, the accommodation of the support frame 3 becomes unstable, and if it exceeds 150 mm, it takes time and effort to weld, and the strength is saturated and meaningless.
As the covering resin layer 33, it is necessary to cover 5 to 10 mm portions below the support frame 3 and the bolt portion 32 with a thermoplastic resin, and the thickness of the covering resin layer 33 is preferably 0.1 to 3 mm. The thermoplastic resin to be coated is preferably the same type or the same kind of easily welded resin as the reinforcing sheet 5 and the thermoplastic resin waterproof sheet 2, and is preferably a vinyl chloride resin, an olefin resin, or an acrylic resin. Although the pedestal 31 is circular in FIG. 8, it is not limited to a circular shape and may be a polygon or other shapes.
When fixing the support frame 3 to the waterproof base 1 through the thermoplastic resin waterproof sheet 2 with the frame fixing screw 312, the base 31 and the thermoplastic resin waterproof sheet are not necessarily required as shown in FIG. Adhesive tape 4 is preferably bonded between the two and this further improves the waterproofness. The pressure-sensitive adhesive tape 4 includes single-sided or double-sided pressure-sensitive adhesive tapes such as butyl, acrylic, and ethylene-vinyl acetate copolymer resin (EVA), but a butyl-based double-sided pressure-sensitive adhesive tape is preferable in terms of waterproofness.

上記増し張りシート５は、支持架台部分の熱可塑性樹脂製防水シート２の防水性を確保するために増し張りされるシートで、支持架台３の台座３１と熱可塑性樹脂製防水シート２とに溶着されるシートであるため、台座３１及びボルト部３２下部の被覆樹脂層３３及び熱可塑性樹脂製防水シート２と同質または同種の溶着しやすい樹脂（塩化ビニル系樹脂、オレフィン系樹脂、アクリル系樹脂等）から形成することが好ましい。増し張りシート５を台座３１と熱可塑性樹脂製防水シート２とに溶着した後、図１に示すように増し張りシート５とボルト部の隙間、熱可塑性樹脂製防水シート２に接する増し張りシート５端部をシーラーＡ５２で防水処理するとよい。シーラーＡ５２としては、被覆樹脂層３３、熱可塑性樹脂製防水シート２、増し張りシート５と同質または同種の樹脂からなるシーラー、或いはウレタン系、変性シリコン系、シリコン系、ブチル系などのシーラーが挙げられる。   The reinforce sheet 5 is a sheet that is reinforced in order to ensure the waterproof property of the thermoplastic resin waterproof sheet 2 in the support frame portion, and is welded to the base 31 of the support frame 3 and the thermoplastic resin waterproof sheet 2. Therefore, the base 31 and the resin layer 33 under the bolt part 32 and the thermoplastic resin waterproof sheet 2 are of the same type or the same type as those easily welded (vinyl chloride resin, olefin resin, acrylic resin, etc. ). After the additional tension sheet 5 is welded to the pedestal 31 and the thermoplastic resin waterproof sheet 2, as shown in FIG. 1, the additional sheet 5 is in contact with the gap between the additional tension sheet 5 and the bolt portion and the thermoplastic resin waterproof sheet 2. The end portion may be waterproofed with a sealer A52. Examples of the sealer A52 include a sealing resin layer 33, a thermoplastic resin waterproof sheet 2, a sealer made of the same or the same kind of resin as the reinforcing sheet 5, or a sealer made of urethane, modified silicon, silicon or butyl. It is done.

上記パネル受け具６は、内側にメネジを有するナット部６２と受け部６１とからなり、複合パネル８を受け部６１で直接支える部材であり、ナット部６２が支持架台のボルト部３２に螺合し高さ調整することが可能になっている。パネル受け具６の受け部６１とナット部６２の形状は円形、多角形のものがよく、他の形状のものも使用できる。
パネル受け具６は、ナット部６２として３０〜１００ｍｍの長尺ナットを用い受け部６１としての厚さ１〜５ｍｍで適宜大きさの鋼板をナット部に溶接して形成してもよく、鋼板をビスでナット部６２のメネジに螺合して形成してもよく（図１はこの形状のパネル受け具６を示す）、ビスで螺合した上に溶接しても良い。また、他の方法でも同形状に形成できればよい。
パネル受け具６の受け部６１には、パネル固定ビス用のネジ切が少なくとも４箇所施されており、複合パネル８を固定できるようになっている。 The panel holder 6 includes a nut portion 62 having a female screw on the inner side and a receiving portion 61, and is a member that is directly supported by the receiving portion 61 of the composite panel 8. The nut portion 62 is screwed onto the bolt portion 32 of the support frame. The height can be adjusted. The shapes of the receiving portion 61 and the nut portion 62 of the panel holder 6 are preferably circular or polygonal, and other shapes can also be used.
The panel holder 6 may be formed by welding a steel plate of an appropriate size with a thickness of 1 to 5 mm as the receiving portion 61 using a long nut of 30 to 100 mm as the nut portion 62. It may be formed by screwing with a female screw of the nut portion 62 with a screw (FIG. 1 shows the panel receiving member 6 having this shape), or may be welded after screwing with a screw. Moreover, what is necessary is just to be able to form in the same shape also by another method.
The receiving portion 61 of the panel holder 6 is threaded for at least four panel fixing screws so that the composite panel 8 can be fixed.

パネル受け具６の緩み防止のため、支持架台３のボルト部３２又はパネル受け具６のナット部６２のメネジにエポキシ系接着剤、ウレタン系接着剤などの接着剤を塗布してパネル受け具６の高さ調整をすることが好ましい。   In order to prevent loosening of the panel holder 6, an adhesive such as an epoxy adhesive or a urethane adhesive is applied to the female part of the bolt part 32 of the support frame 3 or the nut part 62 of the panel holder 6, so that the panel holder 6. It is preferable to adjust the height.

上記複合パネル８は、熱可塑性樹脂製防水シート２の保護と仕上げ材として用いられるものであり、増し張り防水シート９と溶着しやすくするため複合パネル８の表面は溶着樹脂層８１が積層されていることが必要である。溶着樹脂層８１の材質としては、後述する増し張り防水シート９と溶着するため、増し張り防水シート９と同質または同種の樹脂（塩化ビニル系樹脂、オレフィン系樹脂、アクリル系樹脂等）であることが好ましい。
複合パネル８の溶着樹脂層８１を積層する基材としては、セメント板，ケイカル板などの無機板、硬質塩化ビニル,ポリカーボネート，ナイロン，アクリル，ポリプロピレン，フェノール，メラミン，エポキシなど硬質の合成樹脂板、鋼板などの金属板などが挙げられ、これらは単独でも２種以上併用して使用してもよい。好ましくは、スチレンフォーム、硬質ウレタンフォームなどの樹脂製フォームを樹脂被覆した金属板で挟み一体的に形成したものがよい。このような構造の複合パネルを使用すれば、軽量でありながら高い強度も得られ断熱性も高くなる。この場合、複合パネルの金属板として、表面側金属板は樹脂被覆された金属板が増し張りシートとの接合及び耐候・耐蝕上必要であるが、裏面側金属板は亜鉛メッキ鋼板やアルミ・亜鉛・マグネシウム複合メッキ鋼鈑やステンレス鋼鈑やこれらに塗装した鋼鈑でも良い。更には、表面側の樹脂被覆鋼鈑の樹脂は日射反射率の高い樹脂組成のものを使用することが好ましい。
複合パネル８の形状は矩形状であるが長方形のものが好ましく、複合パネル８の寸法は短辺×長辺で３００×１２００〜１２００×２５００ｍｍがよく、６００×１３５０〜９００×１８００ｍｍがより好ましい。複合パネル８の厚さは２０〜７０ｍｍがよく、３０〜５０ｍｍがより好ましい。
支持架台３は複合パネル８の寸法に合わせて所定位置に固定するため、複合パネル８の短辺の寸法が３００ｍｍ未満又は複合パネル８の長辺の寸法が１２００ｍｍ未満では支持架台３の必要数が増しコストアップになり、複合パネル８の短辺の寸法が１２００ｍｍを越えるか又は複合パネル８の長辺の寸法が２５００ｍｍを越えると複合パネル８の強度を確保するため複合パネル８を厚くする必要がありコストアップにつながり好ましくない。 The composite panel 8 is used as a protection and finishing material for the thermoplastic resin waterproof sheet 2, and the surface of the composite panel 8 is laminated with a weld resin layer 81 so as to be easily welded to the additional waterproof sheet 9. It is necessary to be. The material of the welded resin layer 81 is the same or the same kind of resin (vinyl chloride resin, olefin resin, acrylic resin, etc.) as that of the additional waterproof sheet 9 because it is welded to the additional waterproof sheet 9 described later. Is preferred.
The base material on which the welded resin layer 81 of the composite panel 8 is laminated includes an inorganic plate such as a cement plate and a calcium plate, a hard synthetic resin plate such as hard vinyl chloride, polycarbonate, nylon, acrylic, polypropylene, phenol, melamine, and epoxy, Examples thereof include a metal plate such as a steel plate, and these may be used alone or in combination of two or more. Preferably, a resin foam such as styrene foam or rigid urethane foam is sandwiched between resin-coated metal plates and integrally formed. If a composite panel having such a structure is used, a high strength can be obtained while being lightweight, and the heat insulation can be enhanced. In this case, as the metal plate of the composite panel, the surface side metal plate is a resin-coated metal plate, and it is necessary for joining to the tension sheet and weathering / corrosion resistance, but the back side metal plate is galvanized steel plate or aluminum / zinc -Magnesium composite plating steel plate, stainless steel plate, and steel plate coated on these may be used. Furthermore, it is preferable to use a resin-coated steel sheet having a resin composition with high solar reflectance.
The shape of the composite panel 8 is rectangular, but is preferably rectangular. The dimensions of the composite panel 8 are preferably 300 × 1200 to 1200 × 2500 mm in terms of short side × long side, and more preferably 600 × 1350 to 900 × 1800 mm. The thickness of the composite panel 8 is preferably 20 to 70 mm, and more preferably 30 to 50 mm.
Since the support frame 3 is fixed at a predetermined position in accordance with the dimensions of the composite panel 8, if the short side dimension of the composite panel 8 is less than 300 mm or the long side dimension of the composite panel 8 is less than 1200 mm, the required number of the support frames 3 is required. If the short side dimension of the composite panel 8 exceeds 1200 mm or the long side dimension of the composite panel 8 exceeds 2500 mm, the composite panel 8 needs to be thickened to ensure the strength of the composite panel 8. It leads to cost increase and is not preferable.

増し張り防水シート９の材質としては、熱可塑性樹脂製防水シート２と同様に、塩化ビニル樹脂系、オレフィン樹脂系、アクリル樹脂系等のものが使用でき、増し張り防水シート９は、厚みが１．０〜３．０ｍｍで、幅が８０〜１２０ｍｍで長尺シート状ものが使用される。 As shown in FIG. 7, the additional waterproof sheet 9 is placed on the composite panel 8 so as to hide the gap between the short side and the long side of the adjacent composite panel 8 and welded to the composite panel 8 to have a floating floor structure. The surface has a waterproof structure.
Before fixing the additional waterproof sheet 9, it is not always necessary, but the thickness of the butt joint of the composite panel 8 is 0.1 to 0.2 mm and the width is 20 to 50 mm as shown in FIG. It is preferable to apply a film made of polyethylene, polypropylene, etc. with a single-sided adhesive, or a buffer joint tape 91 cross-reinforced with polyester fiber or the like on the film, whereby the composite waterproofing sheet 9 is cracked by the movement of the composite panel 8. Can be suppressed.
As the material of the reinforcing waterproof sheet 9, a vinyl chloride resin type, olefin resin type, acrylic resin type or the like can be used similarly to the thermoplastic resin waterproof sheet 2, and the additional waterproof sheet 9 has a thickness of 1 A long sheet having a width of 0.0 to 3.0 mm and a width of 80 to 120 mm is used.

上記の架台固定ビス３１２は、熱可塑性樹脂製防水シート２と支持架台３を同時に防水下地に固定するものであり、パネル固定ビス６３は複合パネル８をパネル受け具６に固定するものであり、それぞれ皿、平頭形状等の市販のビスが使用できる。防錆を考慮するとステンレス製のものがよい。   The gantry fixing screw 312 is for fixing the thermoplastic resin waterproof sheet 2 and the support gantry 3 to the waterproof base at the same time, and the panel fixing screw 63 is for fixing the composite panel 8 to the panel holder 6. Commercially available screws such as plates and flat heads can be used for each. In consideration of rust prevention, stainless steel is preferable.

FIG. 2 shows a second embodiment. In the second embodiment, a waterproof treatment is performed by using a resin-coated steel sheet 10 instead of the additional waterproof sheet 9 used in the first embodiment.
The process of mounting the composite panel 8 on the receiving part 61 of the panel holder 6 is the same as that of the first embodiment until the female screw of the nut part 62 of the panel holder 6 is screwed into the bolt part 32 of the support frame and the height is adjusted. After that, the resin-coated steel sheet 10 is placed on the composite panel 8 at the same position as the position where the additional waterproof sheet 9 is placed in the first embodiment, and the panel-fixing screw 63 is used to composite the resin-coated steel sheet from above. The panel 8 is fixed to the receiving part 61 of the panel holder 6 and the end of the resin-coated steel plate 10 and the periphery of the head of the panel fixing screw are waterproofed with a sealer B101.

［実施の形態３］
図３に実施の形態３を示す。実施の形態３では、実施の形態１で使用したパネル受け具６の替わりに、パネル用長尺受け具７を用いるもので、支持架台３を取り付ける工程までは実施の形態１と同じため図３では、防水下地に固定するまでの増し張りシート等の部材は省略してある。この形態は支持架台３のボルト部３２に高さ調整しながら、パネル用長尺受け具７を固定し、パネル用長尺受け具７上に複合パネル８を載置し、ドリルビス７５で複合パネル８の上から複合パネル８をパネル用長尺受け具７に固定し、隣り合う複合パネル８の目地部を増し張り防水シート９で覆い防水処理を施す構成である。１本のパネル用長尺受け具７は複数個の支持架台３に固定される。複合パネル８の幅に見合う間隔を開けて複数のパネル用長尺受け具７を平行に固定できるように、支持架台３を位置決めして防水下地１に固定しておく必要がある。
支持架台３の取り付け工程までは実施の形態１と同じであるが、その後は、支持架台３のボルト部３２にパネル用長尺受け具７を固定するものであり、パネル用長尺受け具７の固定方法としては、図３のように支持架台３のボルト部３２に長尺ナット７１を螺合しながら高さ調整し、下面にビス用の穴を開けたパネル用長尺受け具７を長尺ナット上端に載せ、ビス用穴を通して固定ボルト７２で固定する方法がある。また、別の態様として、図４のように支持架台３のボルト部３２に支持架台３のボルト部３２が突出するように第一のナット７３を高さ調整しながら螺合し、ボルト部３２が通るように穴を開けたパネル用長尺受け具７を第一のナット７３まで差込み第二のナット７４を支持架台３のボルト部３２に螺合して固定する方法などがある。図４は、図３の右又は左半分を示し長尺ナット７１と固定ボルト７２の替わりに第一のナット７３と第二のナット７４を使用しており、図３と同じ符号のものは一部省略している。

FIG. 3 shows a third embodiment. In the third embodiment, instead of the panel receiver 6 used in the first embodiment, a long panel receiver 7 is used, and the process up to attaching the support frame 3 is the same as that in the first embodiment, so FIG. Then, members, such as an additional tension sheet until it fixes to a waterproof base | substrate, are abbreviate | omitted. In this embodiment, while adjusting the height to the bolt part 32 of the support frame 3, the long panel receiving device 7 is fixed, the composite panel 8 is placed on the long panel receiving device 7, and the composite panel 8 is mounted with a drill screw 75. The composite panel 8 is fixed to the long panel holder 7 from above 8, and the joint portion of the adjacent composite panel 8 is increased and covered with a waterproof sheet 9 for waterproofing. One long panel holder 7 is fixed to a plurality of support frames 3. The support base 3 needs to be positioned and fixed to the waterproof base 1 so that the plurality of long panel receiving devices 7 can be fixed in parallel with an interval corresponding to the width of the composite panel 8.
The process up to the mounting step of the support frame 3 is the same as that of the first embodiment, but thereafter, the long panel holder 7 is fixed to the bolt portion 32 of the support frame 3. As shown in FIG. 3, the length of the panel holder 7 is adjusted by adjusting the height while screwing the long nut 71 into the bolt portion 32 of the support base 3 and having a screw hole on the lower surface. There is a method of mounting on the upper end of the long nut and fixing with a fixing bolt 72 through a screw hole. As another aspect, the first nut 73 is screwed while adjusting the height so that the bolt part 32 of the support frame 3 protrudes from the bolt part 32 of the support frame 3 as shown in FIG. For example, there is a method of inserting the long panel holder 7 having a hole so as to pass through to the first nut 73 and screwing the second nut 74 into the bolt portion 32 of the support frame 3 to fix it. 4 shows the right or left half of FIG. 3 in which a first nut 73 and a second nut 74 are used in place of the long nut 71 and the fixing bolt 72. The part is omitted.
After fixing the panel long support 7, the composite panel 8 is sequentially placed on the adjacent panel long reception 7 fixed in parallel while opening a joint width of 2 to 10 mm. The joint is preferably loaded with a buffer joint material 82 made of synthetic resin such as foamed polyethylene, rubber, urethane, and vinyl chloride resin or glass nonwoven fabric.
Next, the composite panel 8 is fixed to the long panel holder 7 with a drill screw 75, and the buffer joint tape 91 is stretched on the joint portion of the composite panel 8 in the same manner as in the first embodiment. The composite panel 8 is welded and joined by heat welding, solvent welding or the like, and waterproofed.

上記パネル用長尺受け具７には、平鋼、角パイプ、溝型鋼、リップ溝型鋼等の鋼材が使用でき、支持架台３のボルト部３２又は固定ボルト７２のネジ径より大きな穴を所定位置にあけてから用いる。
パネル用長尺受け具７が平鋼の場合、固定ボルト７２の頭部、第二のナット７４がパネル用長尺受け具７の上面に出るため、固定ボルト７２の頭部、第二のナット７４が収まるように複合パネル８の四隅を切除するか、複合パネル８の間隔をあける必要がある。パネル用長尺受け具７が溝型鋼、リップ溝型鋼の場合、溝を上にして使用すれば、固定ボルト７２の頭部、第二のナット７４は溝内に収まる。溝型鋼の場合、ドリルビス７５は下面部に固定でき、リップ溝型鋼の場合、ドリルビス７５はリップ部及び／又は下面部に固定できる。パネル用長尺受け具７が角パイプの場合、上面部に固定ボルト７２の頭部又は第二のナット７４が挿入できる穴を開ける必要がある。
パネル用長尺受け具７は施工性、強度を考慮するとリップ溝型鋼が好ましく、鋼材の厚みが１．２〜２．３ｍｍ、幅が４０〜１００ｍｍ、長さが１８００〜４０００ｍｍのものがよい。 The long panel receiving member 7 can be made of steel such as flat steel, square pipe, grooved steel, lip grooved steel, and a hole larger than the screw diameter of the bolt portion 32 of the support frame 3 or the fixing bolt 72 is provided at a predetermined position. Use after opening.
When the panel long receiving member 7 is flat steel, the head of the fixing bolt 72 and the second nut 74 come out on the upper surface of the panel long receiving member 7, so the head of the fixing bolt 72 and the second nut It is necessary to cut off the four corners of the composite panel 8 so as to accommodate 74, or to leave a space between the composite panels 8. When the panel long receiving member 7 is a grooved steel or a lip grooved steel, the head of the fixing bolt 72 and the second nut 74 can be accommodated in the groove if the grooved steel is used with the groove facing up. In the case of groove steel, the drill screw 75 can be fixed to the lower surface portion, and in the case of lip groove steel, the drill screw 75 can be fixed to the lip portion and / or the lower surface portion. When the panel long receiving member 7 is a square pipe, it is necessary to make a hole in the upper surface portion into which the head of the fixing bolt 72 or the second nut 74 can be inserted.
In consideration of workability and strength, the long panel receiver 7 is preferably a lip groove type steel, and preferably has a steel material thickness of 1.2 to 2.3 mm, a width of 40 to 100 mm, and a length of 1800 to 4000 mm.

上記ドリルビス７５は、鋼板に下穴をあけるとともに、タップ立て、締め付けが同時にできるものでセルフドリリングスクリューとも云われ、頭部の形状にはナベ、座付六角、皿、丸皿、平、座付ナベなどがあるが、平、皿形状のものが好ましい。ドリルビス７５の替わりに架台固定ビス、パネル固定ビスと同様のビスを使用することもできるが、パネル用長尺受け具７に下穴、ネジ切等を施すなどの手間が増える。   The drill screw 75 is a self-drilling screw that can be used to make a pilot hole in a steel plate and tapping and tightening at the same time. The shape of the head is a pan, a hexagon with a seat, a dish, a round dish, a flat, and a seat. There are pans and the like, but flat and dish-shaped ones are preferred. A screw similar to the frame fixing screw or the panel fixing screw can be used in place of the drill screw 75, but the time and effort required for preparing a long hole for the panel, threading, etc. is increased.

複合パネル８の受け具を長尺にすることにより、支持架台位置で複合パネル８を固定する必要性がなくなり、パネル用長尺受け具７のどの位置での固定も可能となり、施工性が向上するばかりでなく、図６のように千鳥格子状に複合パネル８を固定でき見栄えを良くすることができる。   By making the receiver of the composite panel 8 long, there is no need to fix the composite panel 8 at the position of the support frame, and it becomes possible to fix the long receiver 7 for the panel at any position, thereby improving the workability. In addition, the composite panel 8 can be fixed in a staggered pattern as shown in FIG. 6 to improve the appearance.

［実施の形態４］
上記実施の形態３の増し張り防水シート９の替わりに、実施の形態２と同様に樹脂被覆鋼板１０を使用して防水処理を施す構成である。 [Embodiment 4]
Instead of the reinforced waterproof sheet 9 of the third embodiment, the resin-coated steel sheet 10 is used for waterproofing as in the second embodiment.

本発明の浮き床構造は、支持架台の台座で熱可塑性樹脂製防水シートを固定するので、熱可塑性樹脂製防水シートと支持架台の下地への固定を同時に行うことができ、部材の削減、工数の低減が図れる。また、支持架台の台座とボルト部下部が熱可塑性樹脂で被覆されているため、増し張りシートで支持架台の台座及び防水シートに加熱溶着または溶剤溶着することができ、その接合は強化され、防水性が充分に確保できる。加えて、隣り合う複合パネルの間を防水処理することにより、防水シート面での防水、複合パネル表面での防水と防水構造を２重にし、防水性を長期間確保することができ、さらに、複数の支持架台と長尺パネル受け具が連結する構造では、浮き床構造としての下地への固定強度が増強され耐久性が増すため、ビルの屋上防水工事など広く利用できる。   Since the floating floor structure of the present invention fixes the thermoplastic resin waterproof sheet on the base of the support frame, the thermoplastic resin waterproof sheet and the support frame can be fixed to the base at the same time, reducing the number of members and man-hours. Can be reduced. In addition, since the base of the support base and the lower part of the bolt part are coated with thermoplastic resin, it can be heat-welded or solvent-welded to the base of the support base and the waterproof sheet with an additional tension sheet, and the bonding is strengthened and waterproof. Sufficient property can be secured. In addition, by waterproofing between adjacent composite panels, the waterproofing on the waterproof sheet surface, the waterproofing on the composite panel surface and the waterproof structure can be doubled, and the waterproofness can be ensured for a long time. In a structure in which a plurality of support bases and a long panel support are connected to each other, the strength of fixing to the ground as a floating floor structure is enhanced and the durability is increased.
