Description

本発明は、建物の基礎上に構築する排水剛床構造と、この排水剛床構造に利用可能な排水断熱パネルに関する。   The present invention relates to a drainage rigid floor structure constructed on the foundation of a building, and a drainage heat insulation panel usable for the drainage rigid floor structure.

図９は、剛床構造１００の斜視概略図である。地面に打設された基礎コンクリートの周縁に沿って、布基礎１２０が立設され、布基礎１２０で囲まれた空間には剛床束１２２が立設される。布基礎１２０上には土台１０２（横梁）が横架され、複数本の柱が土台１０２上に立設される。また、剛床束１２２上には、土台１０２と平行又は直角方向に大引き１０４（横梁）が固定される。そして、この大引き１０４に直角に補助大引き１０６が横架され、土台１０２と大引き１０４と補助大引き１０６の総称である横梁１０８が相互に交差して複数の長方形状空隙部１０１が区画され、当該横梁１０８（土台１０２、大引き１０４、補助大引き１０６）上に構造用合板１１０を配置する。   FIG. 9 is a schematic perspective view of the rigid floor structure 100. A cloth foundation 120 is erected along the periphery of the foundation concrete placed on the ground, and a rigid floor bundle 122 is erected in a space surrounded by the cloth foundation 120. A base 102 (horizontal beam) is placed on the fabric foundation 120, and a plurality of pillars are erected on the base 102. On the rigid floor bundle 122, a large pull 104 (horizontal beam) is fixed in a direction parallel to or perpendicular to the base 102. Then, the auxiliary pull 106 is mounted at right angles to the pull 104, and the base 102, the pull 104 and the cross beam 108, which is a generic name of the auxiliary pull 106, cross each other to define a plurality of rectangular voids 101. Then, the structural plywood 110 is disposed on the cross beam 108 (base 102, large pull 104, auxiliary large pull 106).

上述のような剛床構造１００においては屋内温度保持のため、図１０（ａ）のように、構造用合板１１０の下に断熱パネル１１２を敷設するのが一般的である。断熱パネル１１２は長方形状空隙部１０１に嵌合され、その側面が密接する横梁１０８（土台１０２、大引き１０４、補助大引き１０６）に、固定手段により固定される。以下、本明細書においては、構造用合板１１０の下で長方形状空隙部１０１に嵌合される断熱パネル１１２を含めて剛床構造１００という。   In the rigid floor structure 100 as described above, in order to maintain the indoor temperature, it is common to lay a heat insulating panel 112 under the structural plywood 110 as shown in FIG. The heat insulating panel 112 is fitted into the rectangular gap 101 and fixed to the cross beam 108 (base 102, large pull 104, auxiliary large pull 106) whose side surfaces are in close contact by fixing means. Hereinafter, in this specification, the rigid floor structure 100 including the heat insulating panel 112 fitted into the rectangular gap 101 under the structural plywood 110 is referred to.

剛床構造１００は、木造建造物を建築する際、基礎コンクリート状の布基礎１２０が立設された後、真っ先に形成されるが、その次工程は剛床構造１００形成後、通常はその翌日から着手される。そのため、完成した剛床構造１００は少なくとも一晩から長ければ数日間風雨に曝されることになり、剛床構造１００の浸水が問題となっていた。   The rigid floor structure 100 is formed first after the foundation concrete-like cloth foundation 120 is erected when constructing a wooden structure, but the next process is usually the next day after the formation of the rigid floor structure 100. It is started from. Therefore, the completed rigid floor structure 100 is exposed to wind and rain for at least one night to several days, and the inundation of the rigid floor structure 100 has been a problem.

すなわち、図１０（ｂ）のように、構造用合板１１０間のわずかな隙間から雨水や夜露が隣接する構造用合板１１０間、更には構造用合板１１０と断熱パネル１１２間に侵入してしまう。このように構造用合板１１０と断熱パネル１１２間に侵入した水分は、断熱パネル１１２と構造用合板１１０間に停留し、後で取り除くことができず、構造用合板１１０の腐食やカビの発生を招くという問題があった。   That is, as shown in FIG. 10 (b), rainwater and night dew enter through a slight gap between the structural plywoods 110 and between the structural plywood 110 and the heat insulating panel 112. In this way, moisture that has entered between the structural plywood 110 and the heat insulating panel 112 is retained between the heat insulating panel 112 and the structural plywood 110 and cannot be removed later. There was a problem of inviting.

剛床構造１００については種々の発明がなされており、特許文献１、２等のように建造物全体の通風性に関するものは多いが、上記のような剛床構造１００への浸水対策に関するものは発見することができない。   Various inventions have been made with respect to the rigid floor structure 100, and there are many things related to the ventilation of the entire building as in Patent Documents 1 and 2, etc. I can't find it.

上記排水断熱パネルが、前記一面を上方にして前記構造用合板に接するように前記長方形状空隙部に嵌合されて、前記排水断熱パネルの前記排水層が、該排水断熱パネルの前記一面側から侵入した水分を前記他面側へ排水可能である。 The drainage rigid floor structure according to the present invention includes a base and a horizontal beam including a large pull fixed on the bundle of rigid floors at a right angle to the base and an auxiliary large pull horizontally mounted at a right angle to the large pull. In a rigid floor structure in which a plurality of rectangular voids are partitioned and a structural plywood is disposed on the transverse beam,
The drainage heat insulation panel is fitted into the rectangular gap so as to contact the structural plywood with the one surface facing upward, and the drainage layer of the drainage heat insulation panel extends from the one surface side of the drainage heat insulation panel. The intruded moisture can be drained to the other surface side.

本発明に係る排水剛床構造は、前記長方形状空隙部に嵌合された上記排水断熱パネルが、該長方形状空隙部を区画する横梁に、固定手段により固定され、嵌合された該長方形状空隙部に固定されてもよい。   In the drainage rigid floor structure according to the present invention, the drainage heat insulation panel fitted in the rectangular gap is fixed by a fixing means to a horizontal beam that defines the rectangular gap, and the rectangular shape is fitted. You may fix to a space | gap part.

本発明に係る排水剛床構造は、前記長方形状空隙部に嵌合された上記排水断熱パネルの前記一面側に余剰した前記剰余部が、該長方形状空隙部を区画する横梁と該横梁上に配置された前記構造用合板間に挟持されてもよい。   In the drainage rigid floor structure according to the present invention, the surplus portion surplus on the one surface side of the drainage heat insulation panel fitted in the rectangular gap portion is formed on the transverse beam and the transverse beam that partition the rectangular gap portion. It may be clamped between the arranged structural plywood.

本発明に係る排水剛床構造は、前記長方形状空隙部に嵌合された上記排水断熱パネルの前記他面側に余剰した前記剰余部が、該長方形状空隙部を区画する横梁に沿って下方に垂下されてもよい。   In the drainage rigid floor structure according to the present invention, the surplus portion surplus on the other surface side of the drainage heat insulation panel fitted in the rectangular gap is downward along a transverse beam that divides the rectangular gap. It may be drooped on.

本発明に係る排水剛床構造は、土台及び該土台と直角に剛床束上に固定された大引き、該大引きと直角に横架された補助大引きを含む横梁が、相互に交差して複数の長方形状空隙部が区画され、該横梁上に構造用合板を配置する剛床構造において、
一面と他面とが側端面により画された平面状の断熱パネルが、該一面を上方にして前記構造用合板に接するように前記長方形状空隙部に嵌合される剛床構造であって、
少なくとも前記断熱パネルの側端面と前記長方形状空隙部を区画する横梁間に排水層が設けられ、該排水層が、該断熱パネルの前記一面側から侵入した水分を前記他面側へ排水可能な剛床構造である。 The drainage rigid floor structure according to the present invention includes a base and a horizontal beam including a large pull fixed on the bundle of rigid floors at a right angle to the base and an auxiliary large pull horizontally mounted at a right angle to the large pull. In a rigid floor structure in which a plurality of rectangular voids are partitioned and a structural plywood is disposed on the transverse beam,
A flat heat insulating panel in which one surface and the other surface are defined by side end surfaces is a rigid floor structure fitted into the rectangular gap so as to contact the structural plywood with the one surface facing upward,
A drainage layer is provided at least between the side end face of the heat insulation panel and the transverse beam that divides the rectangular gap, and the drainage layer can drain moisture that has entered from the one surface side of the heat insulation panel to the other surface side. A rigid floor structure.

本発明に係る排水剛床構造において、前記排水層は、前記横梁の、前記断熱パネルと接する側面と前記構造用合板と接する上面とに被覆された吸水性繊維であってよい。
In the drainage rigid floor structure according to the present invention, the drainage layer may be a water-absorbing fiber coated on a side surface of the transverse beam that contacts the heat insulating panel and an upper surface that contacts the structural plywood.

本発明に係る排水断熱パネルは、断熱パネルの側端面に排水層を形成するので、断熱パネルの一面側又は他面側から水分を吸収して他面側又は一面側へ排水することができる。   Since the drainage heat insulation panel according to the present invention forms a drainage layer on the side end face of the heat insulation panel, it can absorb moisture from one side or the other side of the heat insulation panel and drain it to the other side or one side.

本発明の排水断熱パネルは、断熱パネルの側端面に吸水性繊維の貼着部を貼着被覆して容易に形成することができる。この吸水性繊維は、上記貼着部の上下、すなわち断熱パネルの一面側及び他面側に剰余部を含んで構成してもよく、あるいは、断熱パネルの一面側又は他面側のいずれか一方側に余剰していてもよいし、又は吸水性繊維は剰余部が無く貼着部のみであってもよい。   The drainage heat insulating panel of the present invention can be easily formed by sticking and covering a sticking portion of a water-absorbing fiber on the side end face of the heat insulating panel. This water-absorbing fiber may be configured to include a surplus part on the upper and lower sides of the sticking part, that is, on one side and the other side of the heat insulation panel, or either one side or the other side of the heat insulation panel. It may be surplus on the side, or the water-absorbing fiber may have no surplus part and only the sticking part.

剰余部の両方を、断熱パネルの一面と他面の両面に貼着させると、商品としてコンパクトで扱いやすいという利点がある。また、剰余部の一方又は両方を、断熱パネルの一面や他面に貼着させずに余剰させておく場合は、この排水断熱パネルを使用する場面において、剰余部を水の溜まりやすい場所に広げて効率的に吸水を行うことができる。また、剰余部を下方に垂下させて用いれば、吸水性繊維（排水層）が吸水した水分を効率的に下方に排水することができる。   Adhering both of the surplus portions to one side and the other side of the heat insulation panel has the advantage of being compact and easy to handle as a product. In addition, when one or both of the surplus portions are to be surplus without being attached to one side or the other side of the heat insulation panel, the surplus portions are spread to a place where water can easily collect in the scene where the drainage heat insulation panel is used. Can absorb water efficiently. Moreover, if the surplus part is used hanging down, the water absorbed by the water absorbent fibers (drainage layer) can be efficiently drained downward.

また、本発明に係る排水剛床構造は、横梁（土台、大引き、補助大引き）上に構造用合板を配置する従来の剛床構造を改良した構造であり、横梁が相互に交差して形成する長方形状空隙部に断熱パネルが嵌合される断熱剛床構造に、排水機能を付与するものである。すなわち、本発明の排水剛床構造は、少なくとも断熱パネルの側端面と長方形状空隙部を区画する横梁間に排水層が設けられ、排水層が、断熱パネルの一面側から侵入した水分を他面側へ排水することができる。   Further, the drainage rigid floor structure according to the present invention is an improved structure of the conventional rigid floor structure in which the structural plywood is arranged on the horizontal beam (base, large pull, auxiliary large pull), and the horizontal beams cross each other. A drainage function is imparted to a heat-insulating rigid floor structure in which a heat-insulating panel is fitted into a rectangular gap to be formed. That is, in the drainage rigid floor structure of the present invention, a drainage layer is provided at least between the side end face of the heat insulation panel and the transverse beam that divides the rectangular gap, and the drainage layer removes moisture that has entered from one side of the heat insulation panel to the other side. Can drain to the side.

本発明に係る排水剛床構造は、例えば、上記の吸水性繊維を貼着させた本発明の排水断熱パネルを、長方形状空隙部に嵌合させて、容易に形成することができる。排水断熱パネルの側端面に貼着させた吸水性繊維が、排水断熱パネルの上方に侵入した水分を吸収して、床下空間側に排水することができる。   The drainage rigid floor structure according to the present invention can be easily formed, for example, by fitting the drainage heat insulation panel of the present invention having the water-absorbing fibers attached thereto into a rectangular gap. The water-absorbing fibers adhered to the side end surfaces of the drainage heat insulation panel can absorb moisture that has penetrated above the drainage heat insulation panel and drain it to the underfloor space.

あるいは、本発明に係る排水剛床構造は、横梁の側面と上面とに吸水性繊維を被覆し、断熱パネルを横梁の側面に被覆した吸水性繊維と接するように長方形状空隙部に嵌合・固定し、横梁の上面に被覆した吸水性繊維の上方から構造用合板を横梁に固定して形成することもできる。このような構成の本発明の排水剛床構造は、隣接する構造用合板間の隙間から侵入する水分をより効果的に吸収して床下空間側に排水することができ、構造用合板下の水分の滞留を防ぐことができる。
Alternatively, the drainage rigid floor structure according to the present invention is fitted to the rectangular gap so that the side and upper surfaces of the cross beam are covered with water absorbent fibers and the heat insulating panel is in contact with the water absorbent fibers covered on the side surfaces of the cross beam. The structural plywood can be fixed to the cross beam from above the water-absorbing fiber fixed and covered on the upper surface of the cross beam. The drainage rigid floor structure of the present invention having such a configuration can absorb water entering from the gap between adjacent structural plywoods more effectively and drain it to the underfloor space side, and the moisture under the structural plywoods Can be prevented.

The drainage layer 20 can be formed by spraying water-absorbing fiber particles or sticking water-absorbing fibers to at least the side end face 18 of the heat insulating panel 12 by flocking or the like.

断熱パネル１２を構成する断熱材は、発泡性合成樹脂材により形成するのが好適であり、いわゆる発泡スチロール材や発泡ウレタン材、発泡フェノール材等により形成してもよいが、断熱性能があれば材料は特に限定されない。また、上記吸水性繊維は、ポリエステルから成る繊維を用いるのが望ましいが、その材料は特に限定されず、吸水性であれば特に限定されない。   The heat insulating material constituting the heat insulating panel 12 is preferably formed of a foamable synthetic resin material, and may be formed of a so-called foamed polystyrene material, a foamed urethane material, a foamed phenol material, or the like. Is not particularly limited. Moreover, it is desirable to use a fiber made of polyester as the water-absorbing fiber, but the material is not particularly limited, and is not particularly limited as long as it is water-absorbing.

図５に示す実施例１に係る排水断熱パネル１０は、断熱パネル１２の側端面１８に吸水性繊維２２を貼着被覆して、排水層２０を形成している。   In the drain heat insulation panel 10 according to the first embodiment shown in FIG. 5, the water absorbing fiber 22 is adhered and coated on the side end face 18 of the heat insulation panel 12 to form the drainage layer 20.

実施例１で用いる吸水性繊維２２は、図４下図のように、断熱パネル１２の側端面１８に貼着被覆される貼着部２２ａの他、断熱パネル１２の一面１４側及び他面１６側に余剰する剰余部２２ｂを含んでもよい。剰余部２２ｂは、図示しないが、一面１４側又は他面１６側のいずれか一方側に余剰していてもよいし、あるいは吸水性繊維２２は剰余部２２ｂが無く貼着部２２ａのみであってもよい。また、断熱パネル１２の側端面１８に貼着被覆される貼着部２２ａは必然的に側端面１８と同様で、例えば図４下図のような帯状であるが、剰余部２２ｂの形状は特に限定されず、使用態様に応じて任意の形状を選択することができる。   As shown in the lower diagram of FIG. 4, the water-absorbing fiber 22 used in the first embodiment includes the one surface 14 side and the other surface 16 side of the heat insulating panel 12 in addition to the bonding portion 22 a that is bonded to the side end surface 18 of the heat insulating panel 12.

Instead, any shape can be selected according to the usage mode.

図２（ａ）〜（ｃ）は、貼着部２２ａの上下に剰余部２２ｂを有する吸水性繊維２２を用いた、本実施例１に係る排水断熱パネル１０の正面図（断面図）を表す。貼着部２２ａが断熱パネル１２の側端面１８に貼着被覆される排水断熱パネル１０は、図２（ａ）のように剰余部２２ｂを断熱パネル１２の一面１４や他面１６に貼着させずに余剰させておいてもよいが、図２（ｂ）、（ｃ）のように剰余部２２ｂの一方又は両方を、一面１４や他面１６に貼着して用いてもよい。   Fig.2 (a)-(c) represents the front view (sectional drawing) of the waste_water | drain heat insulation panel 10 which concerns on the present Example 1 using the water absorbing fiber 22 which has the surplus part 22b on the upper and lower sides of the sticking part 22a. . The drainage heat insulation panel 10 in which the sticking part 22a is stuck to the side end face 18 of the heat insulation panel 12 causes the surplus part 22b to stick to the one surface 14 and the other surface 16 of the heat insulation panel 12 as shown in FIG. However, one or both of the surplus portions 22b may be adhered to the one surface 14 or the other surface 16 as shown in FIGS. 2 (b) and 2 (c).

図２（ｃ）のように剰余部２２ｂの両方を、断熱パネル１２の一面１４や他面１６に貼着させると、商品としてコンパクトで扱いやすいという利点がある。また、図２（ａ）、（ｂ）のように剰余部２２ｂの一方又は両方を、断熱パネル１２の一面１４や他面１６に貼着させずに余剰させておく場合は、この排水断熱パネル１０を使用する場面において、剰余部２２ｂを水の溜まりやすい場所に広げて効率的に吸水を行うことができる。また、剰余部２２ｂを下方に垂下させて用いれば、吸水性繊維２２（排水層２０）が吸水した水分を効率的に下方に排水することができる。   When both of the surplus portions 22b are attached to the one surface 14 and the other surface 16 of the heat insulation panel 12 as shown in FIG. 2C, there is an advantage that the product is compact and easy to handle. In addition, in the case where one or both of the surplus portions 22b are left without being attached to the one surface 14 or the other surface 16 of the heat insulation panel 12 as shown in FIGS.

The cross beam 108 including the auxiliary auxiliary pull 106 is an improved structure of the conventional rigid floor structure in which a plurality of rectangular gaps 101 are defined by intersecting each other and the structural plywood 110 is disposed on the cross beam 108. . The drainage rigid floor structure 1 of the present invention has a rectangular gap so that a planar heat insulation panel 12 having one surface 14 and another surface 16 defined by a side end surface 18 is in contact with the structural plywood 110 with the one surface 14 facing upward. A drainage function is imparted to the heat-insulating rigid floor structure fitted to the portion 101.

本発明に係る排水剛床構造１は、図６（ａ）、（ｂ）のように、少なくとも断熱パネル１２の側端面１８と長方形状空隙部１０１を区画する横梁１０８間に排水層２０が設けられ、排水層２０が、断熱パネル１２の一面１４側から侵入した水分を他面１６側へ排水可能である。   In the drainage rigid floor structure 1 according to the present invention, as shown in FIGS. 6A and 6B, a drainage layer 20 is provided between at least the side end face 18 of the heat insulation panel 12 and the lateral beam 108 that divides the rectangular gap 101. Thus, the drainage layer 20 can drain the moisture that has entered from the one surface 14 side of the heat insulating panel 12 to the other surface 16 side.

図６（ｂ）に示す本実施例２に係る排水剛床構造１において、排水層２０は、横梁１０８の、断熱パネル１２と接する側面と構造用合板１１０と接する上面とに被覆された吸水性繊維２２である。   In the drainage rigid floor structure 1 according to the second embodiment shown in FIG. 6 (b), the drainage layer 20 is a water-absorbing layer coated on the side surface of the cross beam 108 that contacts the heat insulating panel 12 and the upper surface that contacts the structural plywood 110. Fiber 22.

本実施例２に係る排水剛床構造１は、図６（ａ）に示すように、横梁１０８の側面と上面とに吸水性繊維２２を被覆し、断熱パネル１２を横梁１０８の側面に被覆した吸水性繊維２２と接するように長方形状空隙部１０１に嵌合・固定し、横梁１０８の上面に被覆した吸水性繊維２２の上方から構造用合板１１０を横梁１０８に固定して形成することができる。   In the drainage rigid floor structure 1 according to the second embodiment, as shown in FIG. 6A, the side surfaces and the upper surface of the cross beam 108 are covered with the water absorbent fibers 22, and the heat insulating panel 12 is covered with the side surface of the cross beam 108. The plywood for structure 110 can be fixed to the cross beam 108 from above the water absorbent fiber 22 that is fitted and fixed to the rectangular gap 101 so as to be in contact with the water absorbent fiber 22 and coated on the upper surface of the cross beam 108. .

本実施例２に係る排水剛床構造１は、図６（ａ）、（ｂ）のように、少なくとも断熱パネル１２の側端面１８と横梁１０８間に形成された吸水性繊維２２（排水層２０）が、構造用合板１１０間の隙間などから侵入した水分を床下空間側へ排水することができる。   As shown in FIGS. 6A and 6B, the drainage rigid floor structure 1 according to the second embodiment has at least a water absorbent fiber 22 (drainage layer 20) formed between the side end face 18 of the heat insulation panel 12 and the cross beam 108. However, moisture that has entered from gaps between the structural plywood 110 can be drained to the underfloor space side.

このような本発明に係る排水剛床構造１は、上述した本発明の排水断熱パネル１０を用いて形成することもできる。   Such a rigid drainage floor structure 1 according to the present invention can also be formed using the above-described drainage heat insulation panel 10 of the present invention.

図３（ａ）、（ｂ）に示す本実施例３に係る排水剛床構造１は、上記図１０のような従来の剛床構造１００と略同一構成である。すなわち、土台１０２及び土台１０２と直角に剛床束１２２上に固定された大引き１０４、大引き１０４と直角に横架された補助大引き１０６を含む横梁１０８が、相互に交差して複数の長方形状空隙部１０１が区画され、横梁１０８上に構造用合板１１０を配置し（図９参照）、長方形状空隙部１０１に断熱パネル１１２を嵌合・固定する。   The drainage rigid floor structure 1 according to the third embodiment shown in FIGS. 3A and 3B has substantially the same configuration as the conventional rigid floor structure 100 as shown in FIG. That is, the cross beam 108 including the base 102 and the large pull 104 fixed on the rigid floor bundle 122 at a right angle to the base 102 and the auxiliary pull at the right angle to the large pull 104 intersects the plurality of cross beams. A rectangular gap 101 is defined, a structural plywood 110 is disposed on the cross beam 108 (see FIG. 9), and a heat insulating panel 112 is fitted and fixed to the rectangular gap 101.

しかし、本発明に係る排水剛床構造１においては、従来の剛床構造１００で用いる断熱パネル１１２に替えて、本発明に係る排水断熱パネル１０を用いる。すなわち、排水断熱パネル１０が、一面１４（又は他面１６）を上方にして構造用合板１１０に接するように長方形状空隙部１０１に嵌合されて、固定手段により横梁１０８に固定される。排水断熱パネル１０の排水層２０が、排水断熱パネル１０の一面１４（又は他面１６）側から侵入した水分を他面１６（又は一面１４）側へ排水させて、床下空間に水分を排水することができる。他面１６を上方にして水分を一面１４側へ排水させても同様であるので、以下図３（ａ）、（ｂ）に示す通り、一面１４を上方に、他面１６を下方（床下空間側）に配置することとする。   However, in the drainage rigid floor structure 1 according to the present invention, the drainage heat insulation panel 10 according to the present invention is used instead of the heat insulation panel 112 used in the conventional rigid floor structure 100. That is, the drain heat insulation panel 10 is fitted into the rectangular gap 101 so as to be in contact with the structural plywood 110 with the one surface 14 (or the other surface 16) facing upward, and is fixed to the cross beam 108 by the fixing means. The drainage layer 20 of the drainage heat insulation panel 10 drains moisture that has entered from the one surface 14 (or other surface 16) side of the drainage heat insulation panel 10 to the other surface 16 (or one surface 14) side, and drains moisture to the underfloor space. be able to. Since it is the same even if water is drained to the one surface 14 side with the other surface 16 up, as shown in FIGS. 3 (a) and 3 (b), the one surface 14 is upward and the other surface 16 is downward (underfloor space). Side).

排水断熱パネル１０は、長方形状空隙部１０１を区画する横梁１０８に、Ｚ型固定具のような固定手段１１４により固定され、嵌合された長方形状空隙部１０１に嵌合される。ここで、固定手段１１４はＺ型固定具に限定されるわけではなく、適切な固定具、固定手段を適宜選択することができる。   The drainage heat insulation panel 10 is fixed to the transverse beam 108 that defines the rectangular gap 101 by a fixing means 114 such as a Z-shaped fixture, and is fitted into the fitted rectangular gap 101. Here, the fixing means 114 is not limited to the Z-type fixing tool, and an appropriate fixing tool and fixing means can be appropriately selected.

図３（ａ）に係る排水剛床構造１は、上記図２（ｂ）の排水断熱パネル１０を長方形状空隙部１０１に嵌合・固定して得ることができる。あるいは、長方形状空隙部１０１に嵌合した上記図２（ａ）の排水断熱パネル１０の一面１４側に余剰した剰余部２２ｂを、長方形状空隙部１０１を区画する横梁１０８と横梁１０８上に配置された構造用合板１１０間に挟持させて得ることもできる。   The drainage rigid floor structure 1 according to FIG. 3A can be obtained by fitting and fixing the drainage heat insulation panel 10 of FIG. 2B to the rectangular gap 101. Alternatively, the surplus portion 22b surplus on the one surface 14 side of the drainage heat insulation panel 10 of FIG. 2A fitted in the rectangular gap 101 is arranged on the cross beam 108 and the cross beam 108 that define the rectangular gap 101. It can also be obtained by being sandwiched between the structural plywood 110 made.

また、図３（ｂ）に係る排水剛床構造１は、長方形状空隙部１０１に嵌合された上記図２（ａ）の排水断熱パネル１０の一面１４側に余剰した剰余部２２ｂが、長方形状空隙部１０１を区画する横梁１０８と横梁１０８上に配置された構造用合板１１０間に挟持された構造である。この図３（ｂ）に係る排水剛床構造１は、隣接する構造用合板１１０間の隙間から入り込む水分を、図３（ａ）に係る排水剛床構造１よりも排水層２０に誘導し易くなるという利点がある。   Further, the drainage rigid floor structure 1 according to FIG. 3 (b) has a surplus portion 22 b that is surplus on the one surface 14 side of the drainage heat insulation panel 10 of FIG. 2 (a) fitted in the rectangular gap 101. This is a structure sandwiched between a cross beam 108 that divides the hollow portion 101 and a structural plywood 110 disposed on the cross beam 108. The drainage rigid floor structure 1 according to FIG. 3 (b) is easier to guide moisture entering through the gap between the adjacent structural plywoods 110 to the drainage layer 20 than the drainage rigid floor structure 1 according to FIG. 3 (a). There is an advantage of becoming.

上記のような図３（ａ）及び図３（ｂ）に係る排水剛床構造１は、長方形状空隙部１０１に嵌合された排水断熱パネル１０の他面１６側に余剰した剰余部２２ｂが、長方形状空隙部１０１を区画する横梁１０８に沿って下方に垂下されているため、排水断熱パネル１０の一面１４側から侵入した水分を、排水層２０を介して、床下空間により逃がしやすいという利点を持っている。   In the drainage rigid floor structure 1 according to FIGS. 3A and 3B as described above, the surplus portion 22b surplus on the other surface 16 side of the drainage heat insulation panel 10 fitted in the rectangular gap 101 is provided. In addition, since it hangs down along the cross beam 108 that divides the rectangular gap 101, the moisture that has entered from the one surface 14 side of the drain heat insulation panel 10 can easily escape to the underfloor space via the drainage layer 20. have.

なお、図示しないが、上記図２（ｃ）の排水断熱パネル１０を長方形状空隙部１０１に嵌合・固定しても、排水断熱パネル１０の一面１４側から侵入し、あるいは一面１４側に溜まった水分を、他面１６側へ排水させることができる。図２（ｃ）の排水断熱パネル１０は、剰余部２２ｂが一面１４と他面１６に貼着されているため、取り扱いが容易で施工時に剰余部２２ｂが邪魔にならないという利点を持っている。   Although not shown, even if the drainage heat insulation panel 10 of FIG. 2C is fitted and fixed to the rectangular gap 101, the drainage insulation panel 10 enters from the one surface 14 side or collects on the one surface 14 side. Water can be drained to the other surface 16 side. The drain heat insulation panel 10 in FIG. 2C has the advantage that the surplus portion 22b is adhered to the one surface 14 and the other surface 16, and therefore the handling is easy and the surplus portion 22b does not get in the way during construction.

本実施例４では、図７（ａ）のように、横梁１０８を組んで形成した左右の長方形状空隙部１０１に、それぞれ断熱パネル１１２（左）と本発明に係る排水断熱パネル１０（右）とを嵌合・固定し、それぞれのパネルの上から図７（ｃ）のように左右２枚の構造用合板１１０を固定した剛床構造１を形成し、その上方から水を滴下させて剛床構造１内に水分を侵入させる比較実験を行った。   In the fourth embodiment, as shown in FIG. 7A, in the left and right rectangular gaps 101 formed by assembling the cross beams 108, respectively, a heat insulation panel 112 (left) and a drain heat insulation panel 10 (right) according to the present invention. Are fitted and fixed to form a rigid floor structure 1 in which two structural plywoods 110 on the left and right sides are fixed from the top of each panel as shown in FIG.

上記台型実験装置を用いて、その中央部に設けた凹部に水を滴下して、２本のスリットを通して、滴下した水がどの程度台部から下方に排水されるか実験を行った。下記ＡとＢの場合について、水の滴下前と後との台型実験装置全体の重さを計測して、水の排水量を比較した。なお、凹部に水を滴下した後、この水分が蒸発するのを防ぐため、凹部をアクリル板で覆って構造用合板１１０の代替とし、蒸発を防止した。
・実験Ａ（発泡スチロール製断熱材１２の排水性能実験）：
凹部に直接水を滴下し、７０時間５０分経過する前後の台型実験装置全体の重さを計測した。
・実験Ｂ（吸水性繊維２２の排水性能実験）：
吸水性繊維２２を凹部にセットして、吸水性繊維２２の両端を２本のスリットに通して図８（ｃ）のように下方に垂下させ、凹部にセットした吸水性繊維２２の中央付近に水を滴下し、２１時間３０分経過する前後の台型実験装置全体の重さを計測した。 Using the above-mentioned trapezoidal experimental device, water was dropped into a concave portion provided in the central portion, and an experiment was conducted to see how much the dropped water is drained downward from the platform through two slits. In the cases of A and B below, the weight of the whole trapezoidal experimental device before and after dropping of water was measured, and the amount of water discharged was compared. In addition, in order to prevent this water | moisture content from evaporating after dripping water to a recessed part, the recessed part was covered with the acrylic board and it replaced with the structural plywood 110, and prevented evaporation.
Experiment A (Experimental drainage performance of the polystyrene foam insulation 12):
Water was dropped directly into the recess, and the weight of the entire trapezoidal experimental apparatus before and after 70 hours and 50 minutes was measured.
Experiment B (drainage performance experiment of the water-absorbing fiber 22):
The water-absorbing fiber 22 is set in the recess, and both ends of the water-absorbing fiber 22 are passed through the two slits and suspended downward as shown in FIG. 8 (c), and near the center of the water-absorbing fiber 22 set in the recess. Water was dripped and the weight of the whole trapezoidal experimental apparatus before and after 21 hours and 30 minutes passed was measured.

１０種類程度の吸水性繊維２２について上記Ｂの排水試験を行ったが、以下に１００％ポリエステル製の吸水性繊維２２に対する排水性能実験Ｂと発泡スチロール製断熱材１２の排水性能実験Ａの結果を示す。   About 10 types of water-absorbing fibers 22 were subjected to the above drainage test B. The results of drainage performance experiment B for 100% polyester water-absorbing fiber 22 and drainage performance experiment A for polystyrene foam insulation 12 are shown below. .

以上のＡとＢの比較実験より、発泡スチロール製断熱材１２では滴下した水の大半（８５％）が凹部にそのまま残ってしまうのに対して、１００％ポリエステル製の吸水性繊維２２に吸収された水は略全て（９５％）が台部の下方に排水されることが確認できた。   From the above comparative experiment between A and B, in the foamed polystyrene heat insulating material 12, most of the dripped water (85%) remained in the recess as it was, but was absorbed by the water absorbent fibers 22 made of 100% polyester. It was confirmed that almost all (95%) of the water was drained below the pedestal.
