本考案は、水道メータを保護する量水器筐、詳
細にはFRP素材によつて強化した量水器筐に関
するものである。[Detailed Description of the Invention] The present invention relates to a water meter housing that protects a water meter, and more specifically to a water meter housing reinforced with FRP material.
現在、水道メーターは地表より約30cm位の深さ
に埋設され、周囲を鋳鉄やコンクリート製の量水
器筐にて囲んで保護するようにしている。 Currently, water meters are buried approximately 30 cm below the ground surface and are protected by surrounding them with a water meter casing made of cast iron or concrete.
これらの量水器筐は、重くて取扱いにくい上
に、特にコンクリート製の筐は割れやすく、鋳鉄
製の筐は錆びて劣化しやすく耐久性が劣る。 These water meter casings are heavy and difficult to handle, and casings made of concrete are particularly prone to breakage, and casings made of cast iron are susceptible to rust and deterioration and have poor durability.
又、熱可塑性樹脂製の量水器筐は、引張り強度
や曲げ強度が小さいため、鉛直荷重や土圧に対し
て弱く、多くの補強リブを設けなければならない
ため、形状が複雑になり、実用性に乏しいもので
ある。 In addition, water meter housings made of thermoplastic resin have low tensile strength and bending strength, so they are weak against vertical loads and earth pressure, and because many reinforcing ribs must be provided, the shape becomes complicated, making it difficult to put into practical use. It is lacking in sex.
本考案は、かかる従来の欠点を解消せんとなさ
れたものであり、その要旨は、上蓋と、筐本体
と、底蓋と、から構成された量水器筐であつて、
前記上蓋をS.M.C主体のFRPで形成するととも
に、筐本体をB.M.C主体のFRPで形成したこと
にある。 The present invention was made to eliminate such conventional drawbacks, and the gist thereof is a water meter casing consisting of a top lid, a casing body, and a bottom lid, which
The above-mentioned upper cover is formed of FRP mainly composed of SMC, and the casing body is formed of FRP mainly composed of BMC.
以下、本考案の実施例を図面に示して説明す
る。本実施例の量水器筐Ａは、上蓋１と、筐本体
２と、底蓋３と、よりなり、筐本体２の上部に上
蓋１を開閉自在に枢着４し、かつ下部に底蓋３を
着脱自在に取付けたものである。 Embodiments of the present invention will be described below with reference to the drawings. The water meter housing A of this embodiment consists of a top lid 1, a housing body 2, and a bottom lid 3. The top lid 1 is pivotally mounted 4 on the top of the housing body 2 so as to be freely openable and closable, and the bottom lid is on the bottom. 3 is removably attached.
ここで前記上蓋１は、上層１ａ及び下層１ｃを
ガラスマツトで形成し、中間層１ｂを熱硬化性樹
脂と短繊維のガラスチツプそれに充填材とよりな

に耐える構造としている。 Here, the upper lid 1 has an upper layer 1a and a lower layer 1c made of glass mat, an intermediate layer 1b made of SMC made of thermosetting resin, short fiber glass chips, and a filler, and a lower layer 1c of glass mat made of glass mat. It has a structure that is thicker than the glass mats used to withstand vertical loads.
筐本体２は、熱硬化性樹脂にタルクや炭酸カル
シウム、顔料等を混合したB.M.Cを筐状の金型内
に入れて圧縮成形したものであり、炭化マグネシ
ウムはガラスチツプと熱硬化性樹脂それに充填材

するものである。 The housing body 2 is made by compression molding BMC, which is a mixture of thermosetting resin with talc, calcium carbonate, pigments, etc., in a housing-shaped mold, and magnesium carbide is made of glass chips, thermosetting resin, and filler. etc. are mixed to even out the strength by uniformly dispersing them, resulting in a very beautiful finished appearance.
尚、B.M.Cのみで筐本体２を成形することは成
形性の面で非常に簡便な方法であるが、水平方向
からの土圧に対して弱い場合がある。この点につ

の内側面にガラスマツト或いはガラスクロスを１
〜３枚ほど配設することによつて、土圧に対して
優れた効果を示し、長側面が内側に反ることを防
止することができる。 Although molding the housing body 2 using only BMC is a very simple method in terms of moldability, it may be vulnerable to earth pressure in the horizontal direction. In this regard, in this invention, the content of glass chips is increased by 10 to 30%.
Although the problem was solved by increasing the number of
Place one piece of glass mat or glass cloth on the inside surface of the
By arranging about three pieces, it is possible to exhibit an excellent effect on earth pressure and prevent the long sides from warping inward.
次に底蓋３は、土中のミミズや不衛生的なゴミ
の侵入を防ぐためのものであり、熱可塑性樹脂に
よつて形成されている。 Next, the bottom cover 3 is for preventing the intrusion of earthworms and unsanitary garbage in the soil, and is made of thermoplastic resin.

蓋１の開閉に支障をきたすことはなかつた。 The water meter casing A is formed from the above-mentioned materials. In one embodiment of the present invention, the upper lid 1 is press-molded to a thickness of 10 m/m, and the upper layer 1a is
JIS No. 100 glass mat, and lower layer 1c
No. 400 glass mat is placed on the top, and the housing body 2 is 7
The vertical load of the product molded from BMC with a wall thickness of m/m and the bottom cover 3 molded from vinyl chloride resin showed a value of 1800 kg or more. Incidentally, the main body 2 of the casing did not deform in any way even with an earth pressure of about 500 kg acting on the sides, and there was no problem in opening and closing the top cover 1 even during one year of testing.
比較のため熱可塑性樹脂製（ABS樹脂）によ
つて上記した同一厚みの筐本体を成形してテスト
した結果、500Kgの側面土圧で１年後には筐本体

蓋の開閉ができなくなつた。 For comparison, we tested a case body with the same thickness as above made of thermoplastic resin (ABS resin), and found that the long side of the case body warped inward after one year due to 500 kg of lateral earth pressure. It was so close to the top cover that I could no longer open and close it.
以上説明したように本考案によれば、上蓋をS.

果を奏するものである。 As explained above, according to the present invention, the top cover is S.
It is made of MC-based FRP, and the main body is made of BMC.
The main body is FRP, but it is molded and a bottom cover is attached to improve hygiene, so it has features that cast iron or concrete water meter cases do not have, namely, it has a large vertical load capacity and can withstand earth pressure. Yes, BMC
Since the main body of the water dispenser is the main body, it improves press moldability, equalizes the distribution of glass fiber and thermosetting resin, reduces variations in strength, and provides a water meter housing with stable quality. It has various effects such as:
