Description

本発明は、下地の上側に敷設された断熱材と、断熱材の上側に敷設された防水シートと、を備える断熱防水構造体に関する。 TECHNICAL FIELD The present invention relates to a heat-insulating waterproof structure including a heat-insulating material laid above a base and a waterproof sheet laid above the heat-insulating material.

上記のような断熱防水構造体として、例えば、特許文献１に記載のものが既に知られている。この断熱防水構造体においては、固定用ディスクによって、断熱材の上側に防水シートが固定されている。また、固定用ディスクは、固定用ビスによって下地に固定されている。 As the above-mentioned heat-insulating waterproof structure, for example, a structure described in Patent Document 1 is already known. In this heat insulating and waterproofing structure, a waterproofing sheet is fixed above the heat insulating material by a fixing disk. Further, the fixing disk is fixed to the base by fixing screws.

特開２０１４−１５２９号公報JP 2014-1529 A

ここで、断熱防水構造体において、長尺の固定部材が断熱材の上面に載置されると共に、ビスによって下地に固定されている場合がある。この場合、防水シートが、断熱材及び固定部材の上側に敷設されると共に、固定部材に固定される。 Here, in the heat insulating and waterproofing structure, a long fixing member may be placed on the upper surface of the heat insulating material and fixed to the base with screws. In this case, the waterproof sheet is laid above the heat insulating material and the fixing member, and is fixed to the fixing member.

このような長尺の固定部材は、断熱材の端部に設けられることが多い。そして、断熱材の端部の近傍では、作業者によって雨仕舞等の作業が行われる。また、長尺の固定部材は、固定用ディスクに比べて、平面視における面積が大きい。従って、長尺の固定部材は、作業者によって踏まれがちである。 Such a long fixing member is often provided at the end of the heat insulating material. Then, in the vicinity of the end of the heat insulating material, an operation such as a rain break is performed by an operator. Further, the long fixing member has a larger area in plan view than the fixing disk. Therefore, the long fixing member tends to be stepped on by an operator.

作業者が固定部材を踏むと、断熱材が圧縮されることに伴い、固定部材が沈み込む。これにより、ビスの頭部が固定部材の上側に突出する。そして、突出したビスの頭部によって防水シートが破損する可能性がある。 When the operator steps on the fixing member, the fixing member sinks as the heat insulating material is compressed. Thereby, the head of the screw protrudes above the fixing member. The waterproof sheet may be damaged by the protruding screw head.

防水シートが破損した場合、破損部分の修復のための作業が必要となる。これにより、作業効率が低下する。 When the waterproof sheet is damaged, work for repairing the damaged part is required. Thereby, work efficiency is reduced.

ここで、特許文献１に記載の発明における補強材を利用することが考えられる。即ち、天板部と、天板部に連結された支持脚部と、を有する補強材を、断熱材に埋設し、固定部材と天板部とを貫通するようにビスを打ち込むことが考えられる。 Here, it is conceivable to use the reinforcing material in the invention described in Patent Document 1. That is, it is conceivable that a reinforcing material having a top plate portion and a support leg portion connected to the top plate portion is embedded in a heat insulating material, and a screw is driven so as to penetrate the fixing member and the top plate portion. .

この構成であれば、作業者が固定部材を踏んだ場合であっても、固定部材が補強材によって支持されるため、固定部材が沈み込むことを回避できる。従って、ビスの頭部が固定部材の上側に突出することを回避できる。 With this configuration, even when the operator steps on the fixing member, the fixing member is supported by the reinforcing member, and therefore, the fixing member can be prevented from sinking. Therefore, it is possible to prevent the head of the screw from protruding above the fixing member.

しかしながら、この構成では、予め天板部にビス孔が形成されている場合、施工の際に、天板部のビス孔と、固定部材においてビスを貫通させる箇所と、の位置合わせが必要となる。従って、固定部材の構造を、補強材に合わせた専用構造として設計する必要がある。さらに、施工の際の位置合わせのために、比較的多くの労力が必要となる。 However, in this configuration, when screw holes are previously formed in the top plate portion, it is necessary to align the screw holes in the top plate portion and the locations where the screws penetrate in the fixing member at the time of construction. . Therefore, it is necessary to design the structure of the fixing member as a dedicated structure corresponding to the reinforcing material. Furthermore, a relatively large amount of labor is required for alignment during construction.

また、予め天板部にビス孔が形成されていない場合、施工の際に、天板部にビス孔を形成する必要がある。これにより、施工の際に比較的多くの労力が必要となる。 If screw holes are not formed in the top panel in advance, it is necessary to form screw holes in the top panel during construction. This requires a relatively large amount of labor during construction.

以上のことから、特許文献１に記載の発明における補強材を利用した場合には、施工コストが増大しがちである。 From the above, when the reinforcing material in the invention described in Patent Document 1 is used, the construction cost tends to increase.

本発明の目的は、ビスの頭部が固定部材の上側に突出することを確実に回避すると共に、施工コストの増大を抑制しやすい断熱防水構造体を提供することである。 An object of the present invention is to provide a heat-insulating waterproof structure that reliably prevents the head of a screw from protruding above a fixing member and easily suppresses an increase in construction cost.

本発明の特徴は、
下地の上側に敷設された断熱材と、
前記断熱材の上面に載置され、ビスによって前記下地に固定された長尺の固定部材と、
前記断熱材及び前記固定部材の上側に敷設され、前記固定部材に固定された防水シートと、
前記下地と前記固定部材との間において、前記断熱材に埋設された支持部材と、を備え、
前記支持部材は、前記断熱材の厚さ方向に沿って延びる第１板状部と、前記第１板状部と交差する方向及び前記断熱材の厚さ方向に沿って延びる第２板状部と、を有し、
前記ビスは、前記固定部材のうち、平面視において前記支持部材が存在しない部位を前記下地に固定していることにある。 The features of the present invention are:
Thermal insulation laid on the upper side of the base,
A long fixing member mounted on the upper surface of the heat insulating material and fixed to the base by screws,
A waterproof sheet laid on the heat insulating material and the fixing member, and fixed to the fixing member,
Between the base and the fixing member, a support member embedded in the heat insulating material,
The support member includes a first plate-shaped portion extending along a thickness direction of the heat insulating material, and a second plate-shaped portion extending along a direction intersecting the first plate portion and a thickness direction of the heat insulating material. And having
The screw fixes a portion of the fixing member where the support member does not exist in plan view to the base.

本発明であれば、支持部材における第１板状部と第２板状部とは、互いに交差する方向に延びている。そのため、支持部材は、水平方向の力を受けても倒れにくい。従って、作業者が固定部材を踏んだ場合であっても、固定部材は、支持部材によって安定的に支持される。 According to the present invention, the first plate-shaped portion and the second plate-shaped portion of the support member extend in directions intersecting each other. Therefore, the support member is unlikely to fall down even if it receives a horizontal force. Therefore, even when the operator steps on the fixing member, the fixing member is stably supported by the support member.

これにより、固定部材が沈み込むことを確実に回避できる。即ち、本発明であれば、ビスの頭部が固定部材の上側に突出することを確実に回避できる。 Thus, it is possible to reliably prevent the fixing member from sinking. That is, according to the present invention, it is possible to reliably prevent the head of the screw from protruding above the fixing member.

しかも、本発明であれば、ビスは、固定部材のうち、平面視において支持部材が存在しない部位を下地に固定している。即ち、ビスを支持部材に貫通させる必要がない。 In addition, according to the present invention, the screw fixes the portion of the fixing member where the support member does not exist in plan view to the base. That is, there is no need to penetrate the screw through the support member.

従って、本発明であれば、支持部材にビス孔を形成する必要がない。また、固定部材においてビスを貫通させる箇所の位置は、平面視において支持部材が存在しない部位であれば、自由に決定することができる。 Therefore, according to the present invention, there is no need to form a screw hole in the support member. In addition, the position of the portion where the screw penetrates in the fixing member can be freely determined as long as the supporting member does not exist in a plan view.

そのため、固定部材の構造を、支持部材に合わせた専用構造として設計する必要がない。さらに、施工の際に、固定部材においてビスを貫通させる箇所の位置を、支持部材の位置に対して厳密に決定する必要がないため、施工の際に必要な労力は比較的少なくなる。 Therefore, it is not necessary to design the structure of the fixing member as a dedicated structure that matches the support member. Further, at the time of construction, it is not necessary to strictly determine the position of the place where the screw is to be penetrated in the fixing member with respect to the position of the support member, so that the labor required at the time of construction is relatively small.

即ち、本発明であれば、施工コストの増大を抑制しやすい。 That is, according to the present invention, it is easy to suppress an increase in construction cost.

以上より、本発明であれば、ビスの頭部が固定部材の上側に突出することを確実に回避すると共に、施工コストの増大を抑制しやすい。 As described above, according to the present invention, it is possible to reliably prevent the head of the screw from protruding above the fixing member and to suppress an increase in the construction cost.

さらに、本発明において、
前記支持部材は、前記第１板状部が前記断熱材の端面に沿う状態で配置されていると好適である。 Further, in the present invention,
It is preferable that the support member is arranged such that the first plate-shaped portion is arranged along an end surface of the heat insulating material.

作業者が固定部材を踏んだ場合、断熱材のうち、断熱材の端面に近い部分が最も大きく圧縮されやすい。 When the operator steps on the fixing member, the portion of the heat insulating material that is closer to the end face of the heat insulating material is most likely to be compressed.

ここで、上記の構成によれば、断熱材のうち、断熱材の端面に近い部分は、第１板状部によって、圧縮されないように確実に保護される。即ち、断熱材のうち、最も大きく圧縮されやすい部分を、圧縮されないように確実に保護することができる。 Here, according to the above configuration, the portion of the heat insulating material that is close to the end surface of the heat insulating material is reliably protected by the first plate-shaped portion from being compressed. That is, the portion of the heat insulating material that is most easily compressed can be reliably protected from being compressed.

さらに、本発明において、
平面視において、前記第１板状部の延びる方向と、前記第２板状部の延びる方向と、は直交していると好適である。 Further, in the present invention,
In a plan view, it is preferable that a direction in which the first plate-shaped portion extends and a direction in which the second plate-shaped portion extends are orthogonal to each other.

第１板状部の延びる方向と、第２板状部の延びる方向と、が直交していない場合、第１板状部または第２板状部に対して垂直な方向の力が作用すると、支持部材が比較的倒れやすい。 When the direction in which the first plate-like portion extends and the direction in which the second plate-like portion extends are not orthogonal, when a force acts in a direction perpendicular to the first plate-like portion or the second plate-like portion, The support member is relatively easy to fall.

ここで、上記の構成によれば、第１板状部に対して垂直な方向の力が作用した場合、その力の方向は、第２板状部の延びる方向と同一である。これにより、第１板状部に対して垂直な方向の力が作用した場合には、支持部材は第２板状部によって支えられるため、倒れにくい。 Here, according to the above configuration, when a force in a direction perpendicular to the first plate-like portion acts, the direction of the force is the same as the direction in which the second plate-like portion extends. Accordingly, when a force in a direction perpendicular to the first plate-shaped portion acts, the support member is supported by the second plate-shaped portion, and thus is less likely to fall.

また、上記の構成によれば、第２板状部に対して垂直な方向の力が作用した場合、その力の方向は、第１板状部の延びる方向と同一である。これにより、第２板状部に対して垂直な方向の力が作用した場合には、支持部材は第１板状部によって支えられるため、倒れにくい。 Further, according to the above configuration, when a force in a direction perpendicular to the second plate-like portion acts, the direction of the force is the same as the direction in which the first plate-like portion extends. Accordingly, when a force in a direction perpendicular to the second plate-shaped portion acts, the support member is supported by the first plate-shaped portion, and thus is less likely to fall.

即ち、上記の構成によれば、支持部材が倒れにくくなる。 That is, according to the above configuration, the support member is less likely to fall.

さらに、本発明において、
平面視での前記固定部材の短手方向において、前記固定部材の長さと、前記支持部材の長さと、は同一であると好適である。 Further, in the present invention,
It is preferable that the length of the fixing member and the length of the support member in the short direction of the fixing member in plan view are the same.

この構成によれば、固定部材は、短手方向の全長に亘って、支持部材により安定的に支持される。 According to this configuration, the fixing member is stably supported by the support member over the entire length in the lateral direction.

また、平面視での固定部材の短手方向において、固定部材の長さよりも支持部材の長さの方が長い場合には、固定部材から支持部材がはみ出ることとなる。そして、支持部材において、固定部材からはみ出た部分は、固定部材の支持のためには不要である。即ち、この場合、支持部材に不要な部分が含まれているため、製造コストが必要以上に増大してしまう。 If the length of the support member is longer than the length of the fixed member in the short direction of the fixed member in plan view, the support member protrudes from the fixed member. The portion of the support member that protrudes from the fixing member is unnecessary for supporting the fixing member. That is, in this case, since the support member includes an unnecessary portion, the manufacturing cost increases more than necessary.

ここで、上記の構成によれば、平面視での固定部材の短手方向において、固定部材から支持部材がはみ出ることはない。従って、製造コストが必要以上に増大してしまう事態を回避することができる。 Here, according to the above configuration, the support member does not protrude from the fixing member in the lateral direction of the fixing member in plan view. Therefore, it is possible to avoid a situation where the manufacturing cost is increased more than necessary.

さらに、本発明において、
平面視での前記固定部材の短手方向において、前記支持部材の長さは、前記固定部材の長さよりも長いと好適である。 Further, in the present invention,
It is preferable that the length of the support member be longer than the length of the fixing member in the lateral direction of the fixing member in plan view.

また、この構成によれば、平面視において、固定部材から支持部材がはみ出ることとなる。これにより、防水シートの敷設前の段階であれば、固定部材の下側に支持部材が設置されていることを目視で容易に確認することができる。 Further, according to this configuration, the support member protrudes from the fixing member in a plan view. Thus, at the stage before the waterproof sheet is laid, it can be easily visually confirmed that the support member is installed below the fixing member.

さらに、本発明において、
前記断熱材の厚さ方向における前記支持部材の長さは、前記断熱材の厚みよりも短いと好適である。 Further, in the present invention,
It is preferable that the length of the support member in the thickness direction of the heat insulating material is shorter than the thickness of the heat insulating material.

この構成によれば、断熱材の厚さ方向において、固定部材は、断熱材に接することができる。従って、断熱材が、固定部材によって下側に押し付けられる構成を実現できる。これにより、断熱材が水平方向に位置ずれしにくくなる。 According to this configuration, the fixing member can be in contact with the heat insulating material in the thickness direction of the heat insulating material. Therefore, a configuration in which the heat insulating material is pressed downward by the fixing member can be realized. This makes it difficult for the heat insulating material to be displaced in the horizontal direction.

下地の上側に断熱材を敷設する工程と、
第１板状部と、前記第１板状部と交差する方向に延びる第２板状部と、を有する支持部材を、前記第１板状部及び前記第２板状部が前記断熱材の上面に対して垂直となる状態で、前記断熱材に埋設する工程と、

The horizontal plate-shaped portion 21 is in contact with the upper surface of the heat insulating material 1. And the screw 6 has penetrated the horizontal plate-shaped part 21.

このように、断熱防水構造体Ａは、下地５と固定部材２との間において、断熱材１に埋設された支持部材４を備えている。 As described above, the heat-insulating waterproof structure A includes the support member 4 buried in the heat insulating material 1 between the base 5 and the fixing member 2.

また、支持部材４は、第１板状部４１と、第２板状部４２と、を有している。図２に示すように、第１板状部４１は、断熱材１の厚さ方向に沿って延びている。また、図１及び図２に示すように、第２板状部４２は、第１板状部４１と交差する方向及び断熱材１の厚さ方向に沿って延びている。より具体的には、図１に示すように、平面視において、第１板状部４１の延びる方向と、第２板状部４２の延びる方向と、は直交している。 Further, the support member 4 has a first plate-shaped portion 41 and a second plate-shaped portion 42.

As shown in FIGS. 1 and 2, the second plate-shaped portion 42 extends in a direction crossing the first plate-shaped portion 41 and in a thickness direction of the heat insulating material 1. More specifically, as shown in FIG. 1, the direction in which the first plate-shaped portion 41 extends and the direction in which the second plate-shaped portion 42 extends are orthogonal to each other in plan view.

このように、支持部材４は、断熱材１の厚さ方向に沿って延びる第１板状部４１と、第１板状部４１と交差する方向及び断熱材１の厚さ方向に沿って延びる第２板状部４２と、を有している。 As described above, the support member 4 extends along the first plate-shaped portion 41 extending along the thickness direction of the heat insulating material 1 and the direction intersecting with the first plate-shaped portion 41 and the thickness direction of the heat insulating material 1.

That is, the first plate-shaped portion 41 and the second plate-shaped portion 42 are connected. Further, as shown in FIG. 1, the support member 4 in the present embodiment is formed in a T shape in plan view.

また、図１及び図２に示すように、第１板状部４１は、断熱材１の端面に沿っている。即ち、支持部材４は、第１板状部４１が断熱材１の端面に沿う状態で配置されている。 Further, as shown in FIGS. 1 and 2, the first plate-shaped portion 41 is along the end surface of the heat insulating material 1. That is, the support member 4 is arranged such that the first plate-shaped portion 41 is along the end surface of the heat insulating material 1.

図１に示すように、平面視での固定部材２の短手方向における固定部材２の長さは、長さＷ１である。また、平面視での固定部材２の短手方向における支持部材４の長さは、長さＷ２である。そして、長さＷ１と長さＷ２とは同一である。尚、この「同一」には、長さＷ１と長さＷ２とが厳密に一致している状態だけではなく、略等しい状態も含まれる。 As shown in FIG. 1, the length of the fixing member 2 in the lateral direction of the fixing member 2 in plan view is the length W1. The length of the support member 4 in the lateral direction of the fixing member 2 in plan view is the length W2. The length W1 and the length W2 are the same. Note that the “same” includes not only a state in which the length W1 and the length W2 exactly match, but also a state in which they are substantially equal.

このように、平面視での固定部材２の短手方向において、固定部材２の長さＷ１と、支持部材４の長さＷ２と、は同一である。 Thus, the length W1 of the fixing member 2 and the length W2 of the support member 4 are the same in the lateral direction of the fixing member 2 in plan view.

また、図１に示すように、ビス６は、平面視において支持部材４と重複しない位置に設けられている。即ち、ビス６は、固定部材２のうち、平面視において支持部材４が存在しない部位を下地５に固定している。 Further, as shown in FIG. 1, the screw 6 is provided at a position that does not overlap with the support member 4 in a plan view. That is, the screw 6 fixes a portion of the fixing member 2 where the support member 4 does not exist in a plan view to the base 5.

〔断熱防水工法について〕
次に、本発明に係る断熱防水工法の実施形態について説明する。 [About insulation and waterproofing method]
Next, an embodiment of the thermal insulation and waterproofing method according to the present invention will be described.

まず、図４に示すように、下地５の上側に複数の断熱材１を敷設する。このとき、敷設された断熱材１同士の間には、溝Ｇが形成されている。尚、本実施形態においては、複数の断熱材１が敷設されているが、本発明はこれに限定されず、１つの断熱材１が敷設されても良い。 First, as shown in FIG. 4, a plurality of heat insulating materials 1 are laid on the upper side of the base 5. At this time, a groove G is formed between the laid heat insulating materials 1. Note that, in the present embodiment, a plurality of heat insulating materials 1 are laid, but the present invention is not limited to this, and one heat insulating material 1 may be laid.

このように、本発明に係る断熱防水工法は、下地５の上側に断熱材１を敷設する工程を備えている。 As described above, the thermal insulation and waterproofing method according to the present invention includes the step of laying the thermal insulator 1 on the upper side of the base 5.

次に、図５に示すように、支持部材４を断熱材１に埋設する。詳述すると、支持部材４における第２板状部４２を溝Ｇに差し込むと共に、支持部材４を下地５の上面に載置する。これにより、第１板状部４１及び第２板状部４２は、断熱材１の上面に対して垂直となる。 Next, as shown in FIG. 5, the support member 4 is embedded in the heat insulating material 1. More specifically, the second plate portion 42 of the support member 4 is inserted into the groove G, and the support member 4 is placed on the upper surface of the base 5. Thereby, the first plate-shaped portion 41 and the second plate-shaped portion 42 are perpendicular to the upper surface of the heat insulating material 1.

このように、本実施形態における断熱防水工法は、第１板状部４１と、第１板状部４１と交差する方向に延びる第２板状部４２と、を有する支持部材４を、第１板状部４１及び第２板状部４２が断熱材１の上面に対して垂直となる状態で、断熱材１に埋設する工程を備えている。 As described above, in the heat insulation and waterproofing method according to the present embodiment, the support member 4 having the first plate-shaped portion 41 and the second plate-shaped portion 42 extending in a direction intersecting with the first plate-shaped portion 41 is provided by the first member. A step of embedding in the heat insulating material 1 in a state where the plate-shaped portion 41 and the second plate-shaped portion 42 are perpendicular to the upper surface of the heat insulating material 1 is provided.

次に、図６に示すように、断熱材１の上面において、支持部材４の上方に長尺の固定部材２を載置する。そして、固定部材２のうち、平面視（図１を参照）において支持部材４が存在しない部位をビス６によって下地５に固定する。このとき、固定部材２を上から押し付けることにより、断熱材１は上下方向に圧縮される。これにより、固定部材２における水平板状部２１の下面が支持部材４に接する状態で、固定部材２が下地５に固定される。 Next, as shown in FIG. 6, the long fixing member 2 is placed above the support member 4 on the upper surface of the heat insulating material 1. Then, a portion of the fixing member 2 where the support member 4 does not exist in a plan view (see FIG. 1) is fixed to the base 5 with screws 6. At this time, by pressing the fixing member 2 from above, the heat insulating material 1 is compressed in the vertical direction. Thus, the fixing member 2 is fixed to the base 5 in a state where the lower surface of the horizontal plate-shaped portion 21 of the fixing member 2 is in contact with the support member 4.

このように、本実施形態における断熱防水工法は、断熱材１の上面において、支持部材４の上方に長尺の固定部材２を載置すると共に、固定部材２のうち、平面視において支持部材４が存在しない部位をビス６によって下地５に固定する工程を備えている。 As described above, according to the heat insulation and waterproofing method in the present embodiment, the long fixing member 2 is placed above the support member 4 on the upper surface of the heat insulating material 1, and the support member 4 The step of fixing the portion where no is present to the base 5 with the screw 6 is provided.

尚、図５に示すように、断熱材１が上下方向に圧縮されていない状態においては、断熱材１の厚みは、厚みＴ２である。また、断熱材１の厚さ方向における支持部材４の長さは、長さＴ１である。そして、長さＴ１は、厚みＴ２よりも短い。 In addition, as shown in FIG. 5, when the heat insulating material 1 is not compressed in the vertical direction, the thickness of the heat insulating material 1 is the thickness T2. The length of the support member 4 in the thickness direction of the heat insulating material 1 is the length T1. The length T1 is shorter than the thickness T2.

このように、断熱材１の厚さ方向における支持部材４の長さＴ１は、断熱材１の厚みＴ２よりも短い。 Thus, the length T1 of the support member 4 in the thickness direction of the heat insulating material 1 is shorter than the thickness T2 of the heat insulating material 1.

次に、図７に示すように、断熱材１及び固定部材２の上側に防水シート３を敷設する。そして、防水シート３を固定部材２に固定する。より具体的には、防水シート３の下面を、固定部材２の上面に溶着する。 Next, as shown in FIG. 7, the waterproof sheet 3 is laid on the heat insulating material 1 and the fixing member 2. Then, the waterproof sheet 3 is fixed to the fixing member 2. More specifically, the lower surface of the waterproof sheet 3 is welded to the upper surface of the fixing member 2.

尚、図７においては、固定部材２における垂れ下がり部２２及び折り返し部２３の図示を省略している。 In FIG. 7, illustration of the hanging portion 22 and the folded portion 23 in the fixing member 2 is omitted.

このように、本実施形態における断熱防水工法は、断熱材１及び固定部材２の上側に防水シート３を敷設すると共に、防水シート３を固定部材２に固定する工程を備えている。 As described above, the thermal insulation waterproofing method according to the present embodiment includes the steps of laying the waterproof sheet 3 above the heat insulating material 1 and the fixing member 2 and fixing the waterproof sheet 3 to the fixing member 2.

以上で説明した構成であれば、支持部材４における第１板状部４１と第２板状部４２とは、互いに交差する方向に延びている。そのため、支持部材４は、水平方向の力を受けても倒れにくい。従って、作業者が固定部材２を踏んだ場合であっても、固定部材２は、支持部材４によって安定的に支持される。 With the configuration described above, the first plate-shaped portion 41 and the second plate-shaped portion 42 of the support member 4 extend in directions intersecting each other. Therefore, the support member 4 is unlikely to fall down even if it receives a horizontal force. Therefore, even when the worker steps on the fixing member 2, the fixing member 2 is stably supported by the support member 4.

これにより、固定部材２が沈み込むことを確実に回避できる。即ち、以上で説明した構成であれば、ビス６の頭部が固定部材２の上側に突出することを確実に回避できる。 Thereby, the fixing member 2 can be reliably prevented from sinking. That is, with the configuration described above, it is possible to reliably prevent the head of the screw 6 from protruding above the fixing member 2.

しかも、以上で説明した構成であれば、ビス６は、固定部材２のうち、平面視において支持部材４が存在しない部位を下地５に固定している。即ち、ビス６を支持部材４に貫通させる必要がない。 Moreover, with the configuration described above, the screw 6 fixes the portion of the fixing member 2 where the support member 4 does not exist in plan view to the base 5. That is, there is no need to make the screw 6 penetrate the support member 4.

従って、以上で説明した構成であれば、支持部材４にビス孔を形成する必要がない。また、固定部材２においてビス６を貫通させる箇所の位置は、平面視において支持部材４が存在しない部位であれば、自由に決定することができる。 Therefore, with the configuration described above, it is not necessary to form a screw hole in the support member 4. In addition, the position of the place where the screw 6 penetrates in the fixing member 2 can be freely determined as long as the support member 4 does not exist in a plan view.

そのため、固定部材２の構造を、支持部材４に合わせた専用構造として設計する必要がない。さらに、施工の際に、固定部材２においてビス６を貫通させる箇所の位置を、支持部材４の位置に対して厳密に決定する必要がないため、施工の際に必要な労力は比較的少なくなる。 Therefore, it is not necessary to design the structure of the fixing member 2 as a dedicated structure corresponding to the support member 4. Further, at the time of construction, it is not necessary to strictly determine the position of the place where the screw 6 is to be penetrated in the fixing member 2 with respect to the position of the support member 4, so that the labor required at the time of construction is relatively small. .

即ち、以上で説明した構成であれば、施工コストの増大を抑制しやすい。 That is, with the configuration described above, it is easy to suppress an increase in construction cost.

従って、以上で説明した構成であれば、ビス６の頭部が固定部材２の上側に突出することを確実に回避すると共に、施工コストの増大を抑制しやすい。 Therefore, with the configuration described above, it is possible to reliably prevent the head of the screw 6 from projecting above the fixing member 2 and to suppress an increase in the construction cost.

〔第１別実施形態〕
上記実施形態においては、図２及び図３に示すように、防水シート３が、断熱材１及び固定部材２だけでなく、側溝Ｓ及びパラペットを覆う状態で敷設されている。しかしながら、本発明はこれに限定されない。 [First Alternative Embodiment]
In the above embodiment, as shown in FIGS. 2 and 3, the waterproof sheet 3 is laid so as to cover not only the heat insulating material 1 and the fixing member 2 but also the side groove S and the parapet. However, the present invention is not limited to this.

以下では、本発明に係る第１別実施形態について、上記実施形態とは異なる点を中心に説明する。以下で説明している部分以外の構成は、上記実施形態と同様である。また、上記実施形態と同様の構成については、同じ符号を付している。 Hereinafter, a first alternative embodiment according to the present invention will be described focusing on differences from the above embodiment. Configurations other than those described below are the same as in the above embodiment. Further, the same components as those in the above embodiment are denoted by the same reference numerals.

図１７は、本発明に係る第１別実施形態における断熱防水構造体Ａの縦断面図である。この第１別実施形態において、防水シート３は、断熱材１及び固定部材２を覆っている。しかしながら、防水シート３は、側溝Ｓ及びパラペットを覆ってはいない。 FIG. 17 is a longitudinal sectional view of a heat-insulating waterproof structure A according to a first different embodiment of the present invention. In the first alternative embodiment, the waterproof sheet 3 covers the heat insulating material 1 and the fixing member 2. However, the waterproof sheet 3 does not cover the side groove S and the parapet.

この第１別実施形態におけるパラペットは、上記実施形態におけるパラペットよりも低い。尚、図１７に示すように、この第１別実施形態における建物は、パラペットの上端が下地５の上端よりも低くなるように設計されている。 The parapet in the first alternative embodiment is lower than the parapet in the above embodiment. As shown in FIG. 17, the building according to the first alternative embodiment is designed such that the upper end of the parapet is lower than the upper end of the base 5.

そして、この第１別実施形態においては、膜状の防水材９が設けられている。図１７に示すように、防水材９は、側溝Ｓを構成する各壁面と、パラペットと、を覆う状態で設けられている。尚、防水材９は、例えばウレタン防水によって設けることができる。 In the first alternative embodiment, a waterproof member 9 in the form of a film is provided. As shown in FIG. 17, the waterproof material 9 is provided so as to cover each wall surface forming the side groove S and the parapet. Note that the waterproof material 9 can be provided by, for example, urethane waterproofing.

また、この第１別実施形態においては、テープ材１０及び押さえ金物１１が設けられている。 In the first alternative embodiment, a tape member 10 and a holding member 11 are provided.

テープ材１０は、防水材９において、固定部材２の垂れ下がり部２２により覆われる部分の表面に貼り付けられている。尚、テープ材１０は、例えばブチルテープにより構成されていても良い。 The tape material 10 is affixed to the surface of a portion of the waterproof material 9 covered by the hanging portion 22 of the fixing member 2. Note that the tape material 10 may be made of, for example, a butyl tape.

また、押さえ金物１１は、水平部１１ａ、鉛直部１１ｂ、延出部１１ｃを有している。鉛直部１１ｂは、固定部材２の垂れ下がり部２２に沿った板状である。そして、鉛直部１１ｂは、垂れ下がり部２２とテープ材１０との間に位置していると共に、テープ材１０の表面に接着されている。 Further, the holding hardware 11 has a horizontal portion 11a, a vertical portion 11b, and an extending portion 11c. The vertical portion 11b has a plate shape along the hanging portion 22 of the fixing member 2. The vertical portion 11b is located between the hanging portion 22 and the tape material 10 and is adhered to the surface of the tape material 10.

水平部１１ａは、水平姿勢の板状であり、鉛直部１１ｂの上端に接続している。また、水平部１１ａは、断熱材１と下地５との間に挟み込まれている。 The horizontal portion 11a has a plate shape in a horizontal posture, and is connected to the upper end of the vertical portion 11b. The horizontal portion 11a is sandwiched between the heat insulating material 1 and the base 5.

延出部１１ｃは、板状であり、鉛直部１１ｂの下端から斜め下方に延びる状態で設けられている。延出部１１ｃの延びる方向は、固定部材２の折り返し部２３に沿っている。そして、延出部１１ｃの下面と、折り返し部２３の上面と、が接触している。 The extension portion 11c is plate-shaped, and is provided so as to extend obliquely downward from the lower end of the vertical portion 11b. The extending direction of the extending portion 11c is along the folded portion 23 of the fixing member 2. The lower surface of the extension portion 11c is in contact with the upper surface of the folded portion 23.

テープ材１０及び押さえ金物１１により、折り返し部２３と防水材９との間を通って風雨等が吹き込むことを防止できる。 The tape member 10 and the holding member 11 can prevent wind and rain from blowing between the folded portion 23 and the waterproof member 9.

また、押さえ金物１１の延出部１１ｃにより、固定部材２における垂れ下がり部２２及び折り返し部２３の変位が規制される。これにより、複数の固定部材２が長手方向に並んだ状態で設けられる場合には、各固定部材２における垂れ下がり部２２及び折り返し部２３の位置が均一になりやすい。 Further, displacement of the hanging portion 22 and the folded portion 23 of the fixing member 2 is regulated by the extending portion 11c of the presser fitting 11. Accordingly, when the plurality of fixing members 2 are provided in a state of being arranged in the longitudinal direction, the positions of the hanging portion 22 and the folded portion 23 in each fixing member 2 tend to be uniform.

尚、以上に記載した各実施形態は一例に過ぎないのであり、本発明はこれに限定されるものではなく、適宜変更が可能である。 The embodiments described above are merely examples, and the present invention is not limited to the embodiments, and can be appropriately changed.

〔その他の実施形態〕
（１）上記実施形態においては、敷設された断熱材１同士の間に溝Ｇが形成されている。しかしながら、本発明はこれに限定されず、溝Ｇが形成されていなくても良い。この場合、図８及び図９に示すように、支持部材４における第２板状部４２の下端面を断熱材１の上面に押し付けることによって、断熱材１に切れ目Ｋを形成しながら、支持部材４を設置しても良い。また、支持部材４における第２板状部４２を、断熱材１の側方から押し付けることによって、断熱材１の側面から切れ目Ｋを形成させても良い。このような方法によっても、支持部材４を断熱材１に埋設することができる。尚、第２板状部４２のうち、断熱材１に押し付ける面の表面積が小さいほど、断熱材１に切れ目Ｋを形成しやすくなる。 [Other embodiments]
(1) In the above embodiment, the grooves G are formed between the laid heat insulating materials 1. However, the present invention is not limited to this, and the groove G may not be formed. In this case, as shown in FIG. 8 and FIG. 4 may be installed. Further, the cut K may be formed from the side surface of the heat insulating material 1 by pressing the second plate-shaped portion 42 of the support member 4 from the side of the heat insulating material 1. With such a method, the support member 4 can be embedded in the heat insulating material 1. Note that the smaller the surface area of the surface of the second plate-shaped portion 42 pressed against the heat insulating material 1, the easier it is to form the cut K in the heat insulating material 1.

（２）図１０に示すように、敷設された断熱材１同士の間に形成される溝Ｇが、格子状であっても良い。この場合、支持部材４における第１板状部４１及び第２板状部４２を溝Ｇに差し込んだ状態で、支持部材４を設置できる。尚、図１０に示す固定部材２は、垂れ下がり部２２及び折り返し部２３を有していない。 (2) As shown in FIG. 10, the grooves G formed between the laid heat insulating materials 1 may be in a lattice shape. In this case, the support member 4 can be installed with the first plate-shaped portion 41 and the second plate-shaped portion 42 of the support member 4 inserted into the groove G. Note that the fixing member 2 shown in FIG. 10 does not have the hanging portion 22 and the folded portion 23.

（３）断熱防水構造体Ａは、陸屋根を有する建物の屋上において、平場の外縁部に設けられていても良いし、平場の中央部に設けられていても良い。また、切妻屋根を有する建物のケラバの近傍に設けられていても良い。 (3) The heat-insulating and waterproofing structure A may be provided on the outer edge of a flat field or on the center of the flat field on the roof of a building having a flat roof. Further, it may be provided near the keraba of a building having a gable roof.

（４）図１１に示すように、支持部材４は、平面視でＬ字状に形成されていても良い。 (4) As shown in FIG. 11, the support member 4 may be formed in an L shape in plan view.

（５）図１２に示すように、平面視において、第１板状部４１の延びる方向と、第２板状部４２の延びる方向と、は直交していなくても良い。また、図１２において、第１板状部４１は断熱材１の端面に沿っていない。即ち、支持部材４は、第１板状部４１が断熱材１の端面に沿わない状態で配置されていても良い。 (5) As shown in FIG. 12, the direction in which the first plate-shaped portion 41 extends and the direction in which the second plate-shaped portion 42 extends may not be orthogonal to each other in plan view. In FIG. 12, the first plate portion 41 does not extend along the end surface of the heat insulating material 1. That is, the support member 4 may be arranged such that the first plate-shaped portion 41 does not extend along the end surface of the heat insulating material 1.

（６）図１３に示すように、支持部材４は、平面視でＸ字状に形成されていても良い。 (6) As shown in FIG. 13, the support member 4 may be formed in an X shape in plan view.

（７）図１４に示すように、支持部材４は、第１板状部４１、第２板状部４２、第３板状部４３、第４板状部４４、第５板状部４５を有していても良い。この場合、図１４に示すように、平面視において、第１板状部４１、第２板状部４２、第３板状部４３、第４板状部４４、第５板状部４５がそれぞれ放射状に延びていても良い。 (7) As shown in FIG. 14, the support member 4 includes a first plate-shaped portion 41, a second plate-shaped portion 42, a third plate-shaped portion 43, a fourth plate-shaped portion 44, and a fifth plate-shaped portion 45. You may have. In this case, as shown in FIG. 14, the first plate portion 41, the second plate portion 42, the third plate portion 43, the fourth plate portion 44, and the fifth plate portion 45 are respectively viewed in plan. It may extend radially.

（８）図１５に示すように、第１板状部４１と第２板状部４２とが離間していても良い。 (8) As shown in FIG. 15, the first plate-shaped portion 41 and the second plate-shaped portion 42 may be separated from each other.

（９）固定部材２における水平板状部２１の下面が支持部材４に接しない状態で、固定部材２が下地５に固定されていても良い。この場合、固定部材２がビス６によって下地５に固定され、固定部材２により断熱材１が圧縮された状態において、圧縮された断熱材１の厚みＴ２よりも、断熱材１の厚さ方向における支持部材４の長さＴ１の方が短くても良い。 (9) The fixing member 2 may be fixed to the base 5 in a state where the lower surface of the horizontal plate-shaped portion 21 of the fixing member 2 is not in contact with the support member 4. In this case, in a state where the fixing member 2 is fixed to the base 5 by the screw 6 and the heat insulating material 1 is compressed by the fixing member 2, the thickness T 2 of the heat insulating material 1 is more than the thickness T 2 of the compressed heat insulating material 1. The length T1 of the support member 4 may be shorter.

（１０）断熱材１の厚さ方向における支持部材４の長さＴ１は、断熱材１の厚みＴ２と同じであっても良いし、断熱材１の厚みＴ２よりも長くても良い。 (10) The length T1 of the support member 4 in the thickness direction of the heat insulating material 1 may be the same as the thickness T2 of the heat insulating material 1, or may be longer than the thickness T2 of the heat insulating material 1.

（１１）平面視での固定部材２の短手方向において、固定部材２の長さは、支持部材４の長さより長くても良いし、短くても良い。 (11) The length of the fixing member 2 in the lateral direction of the fixing member 2 in plan view may be longer or shorter than the length of the support member 4.

例えば、図１６に示す断熱防水構造体Ａにおいては、上記実施形態における支持部材４の代わりに、支持部材７が備えられている。支持部材７は、第１板状部７１と、第２板状部７２と、を有している。そして、支持部材７は、上記実施形態における支持部材４と同様に、平面視でＴ字状に形成されている。 For example, in a heat-insulating waterproof structure A shown in FIG. 16, a support member 7 is provided instead of the support member 4 in the above embodiment. The support member 7 has a first plate-shaped portion 71 and a second plate-shaped portion 72. The support member 7 is formed in a T-shape in plan view, like the support member 4 in the above embodiment.

ここで、図１６に示すように、平面視での固定部材２の短手方向における固定部材２の長さは、長さＷ１である。また、平面視での固定部材２の短手方向における支持部材７の長さは、長さＷ３である。そして、長さＷ３は、長さＷ１よりも長い。 Here, as shown in FIG. 16, the length of the fixing member 2 in the lateral direction of the fixing member 2 in plan view is the length W1. The length of the support member 7 in the lateral direction of the fixing member 2 in plan view is the length W3. And length W3 is longer than length W1.

これにより、平面視において、固定部材２から支持部材７がはみ出ることとなる。これにより、防水シート３の敷設前の段階であれば、固定部材２の下側に支持部材７が設置されていることを目視で容易に確認することができる。 Thus, the support member 7 protrudes from the fixing member 2 in a plan view. Thus, at the stage before the laying of the waterproof sheet 3, it can be easily visually confirmed that the support member 7 is installed below the fixing member 2.

このように、平面視での固定部材２の短手方向において、支持部材７の長さＷ３は、固定部材２の長さＷ１よりも長い。 Thus, the length W3 of the support member 7 is longer than the length W1 of the fixing member 2 in the short direction of the fixing member 2 in plan view.

（１２）上記実施形態においては、固定部材２と支持部材４とが別体である。しかしながら、本発明はこれに限定されず、固定部材２と支持部材４とは一体形成されていても良い。 (12) In the above embodiment, the fixing member 2 and the support member 4 are separate bodies. However, the present invention is not limited to this, and the fixing member 2 and the support member 4 may be formed integrally.

本発明は、陸屋根だけではなく、傾斜屋根や壁にも利用することができる。 The present invention can be used not only for flat roofs but also for sloping roofs and walls.
