以下、本発明の実施形態について図を参照して説明する。
まず、図1乃至図5に基づいて第1の実施形態を説明する。図1(a)は本実施形態に係る壁体10の正面図、(b)はX−X線での一部断面の側面図である。
図1に示すように、壁体10は、枠体11と、枠体11内に設置されたいわゆるボード系の板状断熱材12と、枠体11の外側を覆う外壁部材としての構造用合板13と、枠体11の内側を覆う図示しない内壁部材(化粧板)とから構成されている。構造用合板13には配向性ストランドボード(OSB)と呼ばれるものなどが用いられる。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, the first embodiment will be described with reference to FIGS. 1 to 5. FIG. 1A is a front view of the wall body 10 according to the present embodiment, and FIG. 1B is a side view of a partial cross section taken by XX rays.
As shown in FIG. 1, the wall body 10 includes a frame body 11, a so-called board-based plate-shaped heat insulating material 12 installed in the frame body 11, and a structural plywood as an outer wall member covering the outside of the frame body 11. It is composed of 13 and an inner wall member (decorative plate) (not shown) that covers the inside of the frame 11. As the structural plywood 13, what is called an oriented strand board (OSB) or the like is used.

枠体11は、木製等の左縦枠11a、右縦枠11b、上横枠11c及び下横枠11dとから構成されている。板状断熱材12は枠体11の内部の空間に充填されている。このような断熱構成は、充填断熱方式と呼ばれており、枠体11、板状断熱材12及び構造用合板13の一体構成は断熱パネル14としてなる。 The frame body 11 is composed of a left vertical frame 11a, a right vertical frame 11b, an upper horizontal frame 11c, and a lower horizontal frame 11d made of wood or the like. The plate-shaped heat insulating material 12 fills the space inside the frame 11. Such a heat insulating structure is called a filling heat insulating method, and the integrated structure of the frame body 11, the plate-shaped heat insulating material 12, and the structural plywood 13 is a heat insulating panel 14.

板状断熱材12は構造用合板13に一体に固定することができる。構造用合板13の上下には、構造用合板13に対する板状断熱材12の位置を規制する規制片13a、13bが固定されている。構造用合板13の下端部には、下横枠11dに対する構造用合板13の位置を規制するスペーサ15が固定されている。スペーサ15によって形成される下方の規制片13bと下横枠11dとの間の隙間16は床面を形成する不図示の根太レス合板を挿入するスペースとなる。 The plate-shaped heat insulating material 12 can be integrally fixed to the structural plywood 13. Restricting pieces 13a and 13b that regulate the position of the plate-shaped heat insulating material 12 with respect to the structural plywood 13 are fixed above and below the structural plywood 13. At the lower end of the structural plywood 13, a spacer 15 that regulates the position of the structural plywood 13 with respect to the lower horizontal frame 11d is fixed. The gap 16 between the lower regulation piece 13b formed by the spacer 15 and the lower horizontal frame 11d serves as a space for inserting the joist-less plywood (not shown) forming the floor surface.

図2に示すように、本実施形態の板状断熱材12は、上下に分割された構成となっている。上側に位置する分割片としての板状断熱材12Aは、発泡樹脂で矩形状に形成された本体部12A−1と、本体部12A−1の長手方向一端部の一部(角部)に設けられた切り欠き部12A−2と、切り欠き部12A−2を覆う嵌め込み部材8とを有している。
切り欠き部12A−2は、本体部12A−1の厚みtよりも浅い深さを持つ矩形状の空間として形成されている。
As shown in FIG. 2, the plate-shaped heat insulating material 12 of the present embodiment has a structure divided into upper and lower parts. The plate-shaped heat insulating material 12A as a divided piece located on the upper side is provided on a main body portion 12A-1 formed of a foamed resin in a rectangular shape and a part (corner portion) of one end portion (corner portion) in the longitudinal direction of the main body portion 12A-1. It has a cutout portion 12A-2 and a fitting member 8 that covers the cutout portion 12A-2.
The cutout portion 12A-2 is formed as a rectangular space having a depth shallower than the thickness t of the main body portion 12A-1.

嵌め込み部材8と切り欠き部12A−2のそれぞれの対向面には凹部とこれに嵌合する凸部とが相対的に形成されており、嵌め込み部材8は切り欠き部12A−2に対して着脱自在となっている。この着脱構成の具体的な説明は後述する。
嵌め込み部材8の1つの角部には、斜めにカットした面取り部8aが形成されている。面取り部8aは、補強金物等の占有スペースの少ないインナー部材との干渉を回避するために設けられている。
A concave portion and a convex portion that fits the concave portion are relatively formed on the facing surfaces of the fitting member 8 and the notch portion 12A-2, and the fitting member 8 is attached to and detached from the notch portion 12A-2. It is free. A specific description of this detachable configuration will be described later.
A chamfered portion 8a cut diagonally is formed at one corner of the fitting member 8. The chamfered portion 8a is provided in order to avoid interference with an inner member such as a reinforcing metal fitting that occupies a small space.

下側に位置する分割片としての板状断熱材12Bは上側の板状断熱材12Aと同一形状であり、向きを逆にして配置されている。逆向きにすることにより、板状断熱材112Aの切り欠き部12A−2が左上に位置するのに対し、板状断熱材12Bの切り欠き部12B−2は右下に位置する。
切り欠き部12B−2に対しても切り欠き部12A−2と同様に嵌め込み部材8が着脱自在に設けられている。
The plate-shaped heat insulating material 12B as a divided piece located on the lower side has the same shape as the plate-shaped heat insulating material 12A on the upper side, and is arranged in the opposite direction. By reversing the orientation, the notch 12A-2 of the plate-shaped heat insulating material 112A is located at the upper left, while the notch 12B-2 of the plate-shaped heat insulating material 12B is located at the lower right.
A fitting member 8 is detachably provided on the notch portion 12B-2 as well as the notch portion 12A-2.

図3に示すように、板状断熱材12A、12Bの流通過程においては、切り欠き部12A−2、12B−2は嵌め込み部材8で塞がれており、表面は段差の無い平坦(面一)な面となっている。
インナー部材を取り付けるときは、必要に応じて嵌め込み部材8が外される。
As shown in FIG. 3, in the distribution process of the plate-shaped heat insulating materials 12A and 12B, the notch portions 12A-2 and 12B-2 are closed by the fitting member 8, and the surface is flat with no steps (flat surface). ).
When attaching the inner member, the fitting member 8 is removed if necessary.

板状断熱材12A、12Bの切り欠き部12A−2、12B−2は、壁体10内に位置する補強金物等のインナー部材の収容空間及び取付作業スペースとしてなる。
本実施形態では、図1(a)及びその部分的拡大図である図4に示すように、上側の板状断熱材12Aの切り欠き部12A−2には、筋交いタイプの補強金物17が収容されている。補強金物17は縦枠11aと横枠11cとの交差箇所に固定されている。
補強金物17は占有スペースが少ないので、図4に示すように、補強金物17を固定した後に嵌め込み部材8が切り欠き部12A−2に押し込んで装着される。
嵌め込み部材8を嵌め込んでも面取り部8aによって補強金物17との干渉を回避することができる。図1(a)では板状断熱材12Aの切り欠き部12A−2に嵌め込まれた嵌め込み部材8を省略している。
The cutout portions 12A-2 and 12B-2 of the plate-shaped heat insulating materials 12A and 12B serve as a storage space and a mounting work space for inner members such as reinforcing hardware located in the wall body 10.
In the present embodiment, as shown in FIG. 1A and FIG. 4 which is a partially enlarged view thereof, the brace type reinforcing metal fitting 17 is housed in the notch portion 12A-2 of the upper plate-shaped heat insulating material 12A. Has been done. The reinforcing hardware 17 is fixed at the intersection of the vertical frame 11a and the horizontal frame 11c.
Since the reinforcing metal fitting 17 occupies a small space, as shown in FIG. 4, after fixing the reinforcing metal fitting 17, the fitting member 8 is pushed into the notch portion 12A-2 to be mounted.
Even if the fitting member 8 is fitted, the chamfered portion 8a can avoid interference with the reinforcing metal fitting 17. In FIG. 1A, the fitting member 8 fitted in the cutout portion 12A-2 of the plate-shaped heat insulating material 12A is omitted.

切り欠き部12A−2の存在により、板状断熱材の施工(充填)後であっても補強金物17を取り付けるための作業スペースを確保することができ、補強金物17を先に取り付けてもその後の板状断熱材の施工において干渉が生じない。
補強金物17を固定した後は切り欠き部12A−2は嵌め込み部材8で覆われるので、切り欠き部12A−2による断熱性の低下が抑制される。
Due to the presence of the notch 12A-2, it is possible to secure a work space for attaching the reinforcing metal fitting 17 even after the installation (filling) of the plate-shaped heat insulating material, and even if the reinforcing metal fitting 17 is attached first, after that. No interference occurs in the construction of the plate-shaped heat insulating material.
After the reinforcing metal fitting 17 is fixed, the notch portion 12A-2 is covered with the fitting member 8, so that the deterioration of the heat insulating property due to the notch portion 12A-2 is suppressed.

一方、下側の板状断熱材12Bの切り欠き部12B−2には、室内の足元付近に位置するコンセントボックス18が収容されている。切り欠き部12B−2はフットライトの収容空間としても利用できる。
板状断熱材12Bにおいても、切り欠き部12B−2の存在により板状断熱材の施工(充填)後であってもコンセントボックス18等を取り付けるための作業スペースを確保することができ、コンセントボックス18等を先に取り付けてもその後の板状断熱材の施工において干渉が生じない。
なお、コンセントボックス18等は補強金物17に比べて占有スペースが大きいので、コンセントボックス18等を取り付けた後には嵌め込み部材8は装着されず、切り欠き部12B−2は開放されたままとなる。
On the other hand, the notch portion 12B-2 of the lower plate-shaped heat insulating material 12B accommodates the outlet box 18 located near the foot in the room. The cutout portion 12B-2 can also be used as a storage space for a footlight.
Even in the plate-shaped heat insulating material 12B, the presence of the notch 12B-2 makes it possible to secure a work space for attaching the outlet box 18 and the like even after the plate-shaped heat insulating material is installed (filled), and the outlet box can be secured. Even if 18 and the like are attached first, interference does not occur in the subsequent construction of the plate-shaped heat insulating material.
Since the outlet box 18 and the like occupy a larger space than the reinforcing hardware 17, the fitting member 8 is not attached after the outlet box 18 and the like are attached, and the notch portion 12B-2 remains open.

このように、板状断熱材12に切り欠き部を形成する構成とすれば、断熱パネルの施工後であっても補強金物等のインナー部材を取り付けるための作業スペースを確保でき、取り付けが可能となる。特にインナー部材を取り付けるための工具の操作用スペースが確保されるので、取付作業が容易となる。
コンセントボックス等のように配線を伴うインナー部材の場合には、切り欠き部は配線の歩留まりを抑制する空間としても機能する。
In this way, if the notch portion is formed in the plate-shaped heat insulating material 12, a work space for attaching the inner member such as the reinforcing hardware can be secured even after the construction of the heat insulating panel, and the mounting is possible. Become. In particular, since a space for operating a tool for mounting the inner member is secured, the mounting work becomes easy.
In the case of an inner member with wiring such as an outlet box, the notch also functions as a space for suppressing the yield of wiring.

また、切り欠き部の存在によってインナー部材との干渉が生じないため、図1(b)から明らかなように、枠体11内の空間の略全体に断熱材を充填できる。
すなわち、発泡倍率の高い安価な断熱材を用いて厚みを大きくできるので、高価で薄肉のボード系断熱材と同等の断熱機能を得ることができる。このため、寒冷地等での使用意義が大きい。
上記のように、切り欠き部12A−2、12B−2は本体部12A−1、12B−1の厚みtよりも浅い深さを有する。このため、切り欠き部の部位でも残りの厚みによって断熱性が得られる。
図2等に示すように、板状断熱材12A、12Bの本体部の前面側の両側には、高さ方向に延びる溝12A−3、12B−3が形成されており、溝12A−3、12B−3は配線通路としてなる。
Further, since the presence of the notch does not cause interference with the inner member, as is clear from FIG. 1B, the heat insulating material can be filled in substantially the entire space in the frame 11.
That is, since the thickness can be increased by using an inexpensive heat insulating material having a high foaming ratio, it is possible to obtain a heat insulating function equivalent to that of an expensive and thin board-based heat insulating material. Therefore, it is of great significance to be used in cold regions.
As described above, the cutout portions 12A-2 and 12B-2 have a depth shallower than the thickness t of the main body portions 12A-1 and 12B-1. For this reason, heat insulating properties can be obtained even at the notched portion depending on the remaining thickness.
As shown in FIG. 2 and the like, grooves 12A-3 and 12B-3 extending in the height direction are formed on both sides of the main body of the plate-shaped heat insulating materials 12A and 12B on the front surface side. 12B-3 serves as a wiring passage.

板状断熱材12の構成材料としては、ポリオレフィン系樹脂やポリスチレン系樹脂等の発泡樹脂による発泡体が挙げられる。
ポリオレフィン系樹脂としては、例えば、ポリプロピレン樹脂やポリエチレン樹脂等が挙げられる。ポリスチレン系樹脂としては、例えば、ポリスチレン樹脂、AS(アクリロニトリル・スチレン)樹脂、ABS(アクリロニトリル・ブタジエン・スチレン)樹脂等が挙げられるが、この限りでない。
Examples of the constituent material of the plate-shaped heat insulating material 12 include a foam made of a foamed resin such as a polyolefin resin and a polystyrene resin.
Examples of the polyolefin resin include polypropylene resin and polyethylene resin. Examples of polystyrene-based resins include, but are not limited to, polystyrene resins, AS (acrylonitrile-styrene) resins, ABS (acrylonitrile-butadiene-styrene) resins, and the like.

板状断熱材12は上下方向に延びる一枚板の形状としてもよいが、上下2枚の分割構成とすることにより、組み合わせパターンにより切り欠き部の位置を変えることができ、種々のインナー部材への対応が容易となる。
図5(a)に示すように、上側の板状断熱材12Aと下側の板状断熱材12Bの向きを同じにすれば、上側の板状断熱材12Aの切り欠き部12A−2の位置が肩口付近となり、例えばスイッチボックス19の収容スペースを確保できる。下側の板状断熱材12Bの切り欠き部12B−2には補強金物17を収容し、下側角部を補強する。
The plate-shaped heat insulating material 12 may have the shape of a single plate extending in the vertical direction, but by dividing the plate-shaped heat insulating material 12 into two upper and lower plates, the position of the notch portion can be changed according to the combination pattern, and various inner members can be used. It becomes easy to deal with.
As shown in FIG. 5A, if the upper plate-shaped heat insulating material 12A and the lower plate-shaped heat insulating material 12B are oriented in the same direction, the position of the cutout portion 12A-2 of the upper plate-shaped heat insulating material 12A Is near the shoulder opening, and for example, a storage space for the switch box 19 can be secured. Reinforcing hardware 17 is housed in the cutout portion 12B-2 of the lower plate-shaped heat insulating material 12B to reinforce the lower corner portion.

本実施形態では、上側の板状断熱材12Aと下側の板状断熱材12Bを同一形状とし、向きを揃えたり変えることにより異なるインナー部材への対応を可能としているので、製造コストの低減を図れるメリットもある。勿論、切り欠き部の位置が左右・上下で異なる形状を個別に作製してもよい。
上記配線通路は板状断熱材の両側に設ける必要はなく、切り欠き部に連通するように片側のみに形成してもよい。両側に形成する構成とすれば、例えば図5(c)に示すように、形状や切り欠き部のパターンが異なる板状断熱材を組み合わせた場合においても配線通路を上下方向に連ねることができる。
In the present embodiment, the upper plate-shaped heat insulating material 12A and the lower plate-shaped heat insulating material 12B have the same shape, and it is possible to correspond to different inner members by aligning or changing the orientation, so that the manufacturing cost can be reduced. There is also a merit that can be planned. Of course, shapes in which the positions of the cutouts are different on the left, right, top and bottom may be individually manufactured.
The wiring passages need not be provided on both sides of the plate-shaped heat insulating material, and may be formed on only one side so as to communicate with the notch. If the configuration is formed on both sides, the wiring passages can be connected in the vertical direction even when plate-shaped heat insulating materials having different shapes and cutout patterns are combined, as shown in FIG. 5 (c), for example.

図5(b)に示すように、一端部と他端部とにそれぞれ切り欠き部12C−2、12C−3を有する板状断熱材12Cとの組み合わせとしてもよい。その際、上側の切り欠き部12C−2には補強金物17を、下側の切り欠き部12C−3にはスイッチボックス19を収容しておくことができる。
さらに、図5(c)に示すように、3分割構成とし、上下方向の中央部に切り欠き部を持たない板状断熱材12Dを配置して高さHの大きい壁体20に対応する構成としてもよい。
切り欠き部の形状も上記に限定されない。各種のインナー部材との干渉を回避できる等の条件を満たす範囲内で適宜に決定することができる。
また、本発明の板状断熱材12の材質は発泡樹脂に限定されない。発泡樹脂以外の材質であっても、インナー部材との干渉を回避するのが困難な材質や構成の場合には同様に実施することができる。これらは以下の他の実施形態においても同様である。
As shown in FIG. 5B, it may be combined with a plate-shaped heat insulating material 12C having notches 12C-2 and 12C-3 at one end and the other end, respectively. At that time, the reinforcing metal fitting 17 can be housed in the upper notch 12C-2, and the switch box 19 can be housed in the lower notch 12C-3.
Further, as shown in FIG. 5C, the configuration is divided into three, and a plate-shaped heat insulating material 12D having no notch is arranged in the central portion in the vertical direction to correspond to the wall body 20 having a large height H. May be.
The shape of the notch is not limited to the above. It can be appropriately determined within a range that satisfies the conditions such as avoiding interference with various inner members.
Further, the material of the plate-shaped heat insulating material 12 of the present invention is not limited to the foamed resin. Even if it is a material other than the foamed resin, it can be carried out in the same manner when it is difficult to avoid interference with the inner member. These are the same in the following other embodiments.

本実施形態では切り欠き部を着脱自在な嵌め込み部材で覆う構成としたが、嵌め込み部材を設けずに切り欠き部を形成するだけの構成としてもよい。 In the present embodiment, the notch portion is covered with a detachable fitting member, but the notch portion may be simply formed without providing the fitting member.

図6乃至図11に基づいて第2の実施形態を説明する。第1の実施形態と同一部分は同一符号で示し、既に説明した構成上及び機能上の説明は適宜省略する。 The second embodiment will be described with reference to FIGS. 6 to 11. The same parts as those in the first embodiment are indicated by the same reference numerals, and the structural and functional explanations already described will be omitted as appropriate.

図6に示すように、本実施形態に係る板状断熱材21は、発泡樹脂で矩形状に形成された本体部22と、本体部22の一端部の一部(角部)に設けられ、本体部22の厚みよりも浅い深さを持つ切り欠き部22aと、本体部22に着脱自在に設けられ、切り欠き部22aを覆う嵌め込み部材22bとを有している。符号22eは配線通路を示している。
本体部22の背面側には、本体部22の長手方向に延びる2本の凸条22c、22dが形成されている。切り欠き部22aには、本体部22の長手方向に延びるスリット23が形成されている。スリット23は製造誤差を吸収して板状断熱材21を枠体11内に緊密に充填する目的で形成されている。
As shown in FIG. 6, the plate-shaped heat insulating material 21 according to the present embodiment is provided on a main body portion 22 formed of a foamed resin in a rectangular shape and a part (corner portion) of one end portion (corner portion) of the main body portion 22. It has a notch portion 22a having a depth shallower than the thickness of the main body portion 22, and a fitting member 22b that is detachably provided on the main body portion 22 and covers the notch portion 22a. Reference numeral 22e indicates a wiring passage.
Two ridges 22c and 22d extending in the longitudinal direction of the main body 22 are formed on the back surface side of the main body 22. The cutout portion 22a is formed with a slit 23 extending in the longitudinal direction of the main body portion 22. The slit 23 is formed for the purpose of absorbing manufacturing errors and tightly filling the plate-shaped heat insulating material 21 in the frame body 11.

切り欠き部22aには、本体部22の長手方向に延びる矩形状の凸部22a−1と、凸部22a−1内に上下方向(長手方向)に分離して形成された矩形状の平面を有する凹部22a−2とが形成されている。
嵌め込み部材22bの対向面には、本体部22の長手方向に延びる矩形状の凹部22b−1と、凹部22b−1内に上下方向(長手方向)に分離して形成された矩形状の平面を有する凸部22b−2とが形成されている。また、嵌め込み部材22bにはインナー部材との干渉を回避するための面取り部22b−3が形成されている。
面取り部22b−3は、L字形の補強金物17’に対応した形状を有している。
The cutout portion 22a has a rectangular convex portion 22a-1 extending in the longitudinal direction of the main body portion 22 and a rectangular flat surface formed in the convex portion 22a-1 separated in the vertical direction (longitudinal direction). A recess 22a-2 having a recess 22a-2 is formed.
On the facing surface of the fitting member 22b, a rectangular recess 22b-1 extending in the longitudinal direction of the main body 22 and a rectangular flat surface formed in the recess 22b-1 separated in the vertical direction (longitudinal direction) are formed. The convex portion 22b-2 to have is formed. Further, the fitting member 22b is formed with a chamfered portion 22b-3 for avoiding interference with the inner member.
The chamfered portion 22b-3 has a shape corresponding to the L-shaped reinforcing metal fitting 17'.

例えば、板状断熱材21を断熱パネルの形態で枠体11に設置した後、L字形の補強金物17’を枠体11に取り付ける。補強金物17’の枠体11への取り付けは、上述のように切り欠き部22aによって作業スペースが存在するので容易に行うことができる。
補強金物17’を取り付けた後、嵌め込み部材22bを切り欠き部22aに押し込んで嵌める。図7に示すように、補強金物17’は面取り部22b−3の空間に収容され、切り欠き部22aに対する嵌め込み部材22bの嵌め込み操作は補強金物17’によって阻害されない。
For example, after the plate-shaped heat insulating material 21 is installed on the frame 11 in the form of a heat insulating panel, the L-shaped reinforcing metal fitting 17'is attached to the frame 11. The reinforcing metal fitting 17'can be easily attached to the frame body 11 because a work space is provided by the cutout portion 22a as described above.
After attaching the reinforcing metal fitting 17', the fitting member 22b is pushed into the notch portion 22a to be fitted. As shown in FIG. 7, the reinforcing metal fitting 17'is housed in the space of the chamfered portion 22b-3, and the fitting operation of the fitting member 22b into the notch portion 22a is not hindered by the reinforcing metal fitting 17'.

切り欠き部22aに嵌め込み部材22bを嵌め込むと、切り欠き部22aの凹部22a−2に嵌め込み部材22bの凸部22b−2が嵌合し、切り欠き部22aの凸部22a−1に嵌め込み部材22bの凹部22b−1が嵌合する。
図10(a)に示すように、嵌め込み部材22bの凹部22b−1は、厚み方向における外側が狭く内側が広い断面形状となっており、逆に切り欠き部22aの凸部22a−1は、厚み方向における外側が広く内側が狭い抜け止め断面形状となっている。
一方、嵌め込み部材22bの凸部22b−2は、厚み方向における外側が広く内側が狭い抜け止め断面形状となっており、逆に切り欠き部22aの凹部22a−2は、厚み方向における外側が狭く内側が広い抜け止め断面形状となっている。また、各凹部と凸部の周縁は曲率の大きい湾曲の断面形状となっている。
When the fitting member 22b is fitted into the notch portion 22a, the convex portion 22b-2 of the fitting member 22b is fitted into the concave portion 22a-2 of the notch portion 22a, and the fitting member is fitted into the convex portion 22a-1 of the notch portion 22a. The recess 22b-1 of 22b fits.
As shown in FIG. 10A, the recess 22b-1 of the fitting member 22b has a cross-sectional shape that is narrow on the outside and wide on the inside in the thickness direction, and conversely, the convex portion 22a-1 of the notch portion 22a has a convex portion 22a-1. It has a retaining cross-sectional shape with a wide outside and a narrow inside in the thickness direction.
On the other hand, the convex portion 22b-2 of the fitting member 22b has a retaining cross-sectional shape having a wide outside in the thickness direction and a narrow inside, and conversely, the concave portion 22a-2 of the notch portion 22a has a narrow outside in the thickness direction. The inside has a wide retaining cross section. Further, each concave portion and the peripheral edge of the convex portion have a curved cross-sectional shape having a large curvature.

このため、切り欠き部22aに嵌め込み部材22bを押圧して嵌め込むと、図10(b)に示すように、両部材の凹凸部それぞれが弾性変形して相手方に入り込み、抜け止めされた状態に強固に密着・嵌合する。嵌合後は嵌め込み部材22bと本体部22の切り欠き部22aを除く部分とが面一(平坦)となるように凹部と凸部の寸法が設定されている。なお、嵌め込み部材22bは本体部22と同一の発泡樹脂とすることが可能である。
切り欠き部22aと嵌め込み部材22bとの間における凹凸の嵌合構成は図6等で示した構成に限定されず、両部材間で相対的に形成されるものである。
例えば、図11に示すように、切り欠き部22aに複数の円柱状の凸部22a−3を形成し、嵌め込み部材22bの対向面に凸部22a−3が嵌合する凹部22b−4を形成してもよい。凹凸の嵌合構成はこの逆でもよい。
第1の実施形態における切り欠き部12A−2、12B−2と嵌め込み部材8との間の嵌合による着脱構成も上記例と同様である。
Therefore, when the fitting member 22b is pressed and fitted into the notch portion 22a, as shown in FIG. 10B, each of the uneven portions of both members is elastically deformed and enters the other party, so that the fitting member 22b is prevented from coming off. Firmly adheres and fits. After fitting, the dimensions of the concave portion and the convex portion are set so that the fitting member 22b and the portion of the main body portion 22 excluding the cutout portion 22a are flush with each other (flat). The fitting member 22b can be made of the same foamed resin as the main body 22.
The uneven fitting configuration between the notch portion 22a and the fitting member 22b is not limited to the configuration shown in FIG. 6 or the like, and is relatively formed between the two members.
For example, as shown in FIG. 11, a plurality of columnar convex portions 22a-3 are formed in the cutout portion 22a, and a concave portion 22b-4 in which the convex portions 22a-3 are fitted is formed on the facing surface of the fitting member 22b. You may. The concavo-convex fitting configuration may be the reverse.
The attachment / detachment configuration by fitting between the notch portions 12A-2 and 12B-2 and the fitting member 8 in the first embodiment is also the same as the above example.
