本発明は、壁面に設置される壁点検口における外枠の取
付構造に関し、特に設置作業が容易で、かつ設置強度の
高い取付構造に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a mounting structure for an outer frame in a wall inspection port installed in a wall surface, and particularly to a mounting structure that is easy to install and has high installation strength. It is.

枠３が所定の位置に保持されないおそれがあり、また、
一時的に保持状態を維持しても点検の際の開閉によって
外枠３が所定の位置からはずれてしまうおそれがある。In this case, there is a gap between the outer frame 3 of the wall inspection port A and the opening 2 of the wall l, and the wall inspection port A tends to move downward due to its own weight. When a force is applied to rotate the support piece 5 in the direction indicated by the arrow, the support piece 5 and the connection piece 8 may bend in a substantially dogleg shape at the connection site, and the outer frame 3 may not be held in a predetermined position.
Even if the holding state is maintained temporarily, there is a risk that the outer frame 3 may come off the predetermined position due to opening and closing during inspection.
したがって、従来この支持片５と連結片８との連結部位

結作業に手間がかかるという問題があった。Therefore, conventionally, a plurality of pairs of bolts 6 and nuts 7 are attached to the connecting portion between the support piece 5 and the connecting piece 8, which has caused the problem that the connecting operation is time-consuming.
本発明は、このような事情に対処してなされたものであ
って、支持片５と連結片８との連結作業を複雑にせず、

おける外枠の取付構造を提供することを目的とする。The present invention has been made in response to such circumstances, and does not complicate the connection work between the support piece 5 and the connection piece 8.
Another object of the present invention is to provide a mounting structure for an outer frame in a wall inspection port that can increase the strength of these connections.

In the figure, a mounting structure of an outer frame 3 in a wall inspection opening A corresponding to an embodiment of the present invention is shown. The outer frame 3 is fixed to the support base 4 via a connecting piece 8.
すなわち、支持基部４からは支持片５が突設され、この
支持片５と上記外枠３の外周裏面とを連結片８により連
結することにより外枠３が開口２内に保持されている。That is, a support piece 5 is provided protruding from the support base 4, and the outer frame 3 is held within the opening 2 by connecting the support piece 5 and the outer peripheral back surface of the outer frame 3 with a connecting piece 8.
そして、上記支持片５と連結片８とは、相互に係合し合
い、この連結部位において回動が不可能な状態とされて
いる。The supporting piece 5 and the connecting piece 8 are engaged with each other, and cannot be rotated at this connecting portion.
〔作 用〕
壁点検口Ａは、壁面ｌに沿って設置されるもので、例え
ば床点検口等と異なり、その自重は、壁面ｌに沿って該
壁点検口Ａをすり下げるように作用する。[Function] The wall inspection port A is installed along the wall surface l, and unlike, for example, a floor inspection port, its own weight acts to slide the wall inspection port A down along the wall surface l. .
したがって、壁点検口Ａにおいては、その自重に対して
有効な構造を提供することにより、全体の構造を複雑に
することなく連結強度を高めることができる。Therefore, in the wall inspection port A, by providing a structure that is effective against its own weight, the connection strength can be increased without complicating the overall structure.
本発明は、この点に着目してなされたものであって、支
持片５と連結片８とを互いに回動不可能な状態に係合し
て連結することにより、この連結部位における補強を図
るものである。The present invention has been made with attention to this point, and by engaging and connecting the supporting piece 5 and the connecting piece 8 in a state where they cannot rotate with each other, reinforcement is achieved at this connecting part. It is something.
以下、本発明の望ましい実施例を添付図面に基づいて詳
細に説明する。Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
第１図において、本発明による壁点検口へにおける外枠
３の取付構造の実施例が示されている。In FIG. 1, an embodiment of a structure for attaching an outer frame 3 to a wall inspection port according to the present invention is shown.
この実施例における外枠３は、例えばアルミニウム材料
からなり、第２図に示すように、主縁部３ａの一端部に
壁面ｌに当接する折曲部３ｂを形成した四本の枠部材を
枠組みして形成され、各枠部材の他端部には、断面略Ｃ
字状の溝形成用突部３ｃが突出され、連結片８をこの外
枠３に連結するための連結ボルト１０の頭部１０ａが摺
動可能でかつ空転しないようにこの溝形成用突部３ｃ内
に嵌入されて、連結片８を外枠３の外周裏面の適宜位置
に装着できるように配慮されている。The outer frame 3 in this embodiment is made of, for example, an aluminum material, and as shown in FIG. The other end of each frame member has a cross section of approximately C.
A letter-shaped groove forming protrusion 3c is projected so that the head 10a of the connecting bolt 10 for connecting the connecting piece 8 to the outer frame 3 can slide and not idle. It is designed so that the connecting piece 8 can be fitted into the outer frame 3 at an appropriate position on the outer circumferential back surface of the outer frame 3.
一方、支持基部４は断面コ字状のチャンネル材で製せら
れ、断面り字状に折曲された支持片５が、ビス１１によ
りこの支持基部４に固定されている。On the other hand, the support base 4 is made of a channel material having a U-shaped cross section, and a support piece 5 bent to have an L-shaped cross section is fixed to the support base 4 with screws 11.
この時、支持片５には、横長の長孔５ａが穿設され、支
持片５の保持部５ｂが壁面ｌに対して前後方向に調節で
きるようにされている。At this time, a horizontally elongated hole 5a is bored in the support piece 5, so that the holding portion 5b of the support piece 5 can be adjusted in the front-back direction with respect to the wall surface l.
また、この実施例においては、第３図に示すように、支
持片５の保持部５ｂに、連結片８と略同様の幅を有する
凹部１２が凹設され、この凹部１２内に連結片８を係合
させることにより、支持片５と連結片８とが互いに回動
不可能な状態とされている。Further, in this embodiment, as shown in FIG. By engaging the supporting piece 5 and the connecting piece 8, the supporting piece 5 and the connecting piece 8 are rendered unable to rotate relative to each other.
この場合凹部１２の内周壁あるいは連結片８の外周壁に
突部を複数個並設することによって支持片５と連結片８
とが圧接状になり、その係合をさらに高めることができ
る。In this case, by arranging a plurality of protrusions in parallel on the inner peripheral wall of the recess 12 or the outer peripheral wall of the connecting piece 8, the supporting piece 5 and the connecting piece 8
The two are in pressure contact, and the engagement can be further enhanced.
なお、第１図ないし第３図に示した実施例においては、
連結片８に長孔８ａを穿設して、この連結片８の設置位
置を調節することができるようにされているが、この他
に例えば第４図に示すように、支持片５側に長孔５ｃを
穿設してもよい。In addition, in the embodiment shown in FIGS. 1 to 3,
A long hole 8a is formed in the connecting piece 8 so that the installation position of the connecting piece 8 can be adjusted.In addition, for example, as shown in FIG. A long hole 5c may be formed.
また、支持片５と連結片８との係合状態はこの実施例に
示されるものに限られるものではなく、第５図に示すよ
うに、支持片５の保持部５ｂに突起５ｄ、５ｄを突設し
、この突起５ｄに連結片８の溝８ｂを係合させるように
したものであってもよい。Furthermore, the engagement state between the support piece 5 and the connection piece 8 is not limited to that shown in this embodiment, and as shown in FIG. The groove 8b of the connecting piece 8 may be engaged with the protrusion 5d.
したがって、この実施例により壁点検口Ａを壁面ｌに固
定するには、まず、調節ボルトＩＯに重合可能な位置に
連結片８を突出させて、ボルト６およびナツト７により
この連結片８を支持片４に固定し、次いで外枠３に装着
されている連結ホト１３により締めつければよい。Therefore, in order to fix the wall inspection opening A to the wall surface l according to this embodiment, the connecting piece 8 is first projected to a position where it can overlap with the adjustment bolt IO, and the connecting piece 8 is supported by the bolt 6 and the nut 7. It is sufficient to fix it to the piece 4 and then tighten it with the connecting photo 13 attached to the outer frame 3.
この時、支持片５と連結片８とは、互いに係合して回動
不可能な状態とされているので、回動力を考慮して二対
のボルト６、ナツト７を使用する必要がなく、この結果
工数の削減を図ることができるのである。At this time, the supporting piece 5 and the connecting piece 8 are engaged with each other and cannot be rotated, so there is no need to use two pairs of bolts 6 and nuts 7 in consideration of rotational force. As a result, it is possible to reduce the number of man-hours.
なお、以上の説明においては、連結ボルトｌＯを外枠の
外周裏面に摺動可能に装着した場合について述べたが、
これに限られるものではな（、従来例として示したよう
なものにも適用が可能なことは勿論である。In addition, in the above explanation, the case where the connecting bolt lO is slidably attached to the outer circumferential back surface of the outer frame has been described.
However, the present invention is not limited to this (it goes without saying that the present invention can also be applied to those shown as conventional examples).
以上の説明から明らかなように、本発明による壁点検口
における外枠の取付構造によれば、支持片と連結片とを
互いに回動不可能な状態に係合して連結したので、これ
らを単に連結するだけで、この連結部位における折れ曲
がりを確実に防ぐことができ、従来のように、複数対の
ボルト、ナツトを使用する必要がなくなり、余分の工数
をがけずに、がっ強固な連結を得ることができる。As is clear from the above description, according to the mounting structure of the outer frame in the wall inspection port according to the present invention, the supporting piece and the connecting piece are engaged and connected in a state where they cannot rotate with each other. By simply connecting them together, you can reliably prevent bending at this connection point, eliminating the need to use multiple pairs of bolts and nuts as in the past, and creating a strong connection without any extra man-hours. can be obtained.
