Abstract

PURPOSE:To prevent an adjuster body from rising by frost-heaving force on a cold zone by a method wherein an electric heating element is put directly about a joint of synthetic resin molded object to weld the joint. CONSTITUTION:The end part 12a of a joint of an adjuster cylinder 12 composed of synthetic resin molding material is fitted in a fitting groove 11a comprising the joint of an inlet body 11 composed of the same material. Nichrome wire 2 is wound spirally on the inner wall surface 11b of a lifting groove 11a from the upper part down to the lower part, the wire arrives at the lower part of the outer wall surface 11c through the groove bottom 11d of the fitting groove 11a and further rises spirally toward the upper part of the outer wall surface 11c. When the nichrome wire 2 is electrified and heated, each of inner and outer wall surfaces 11b, 11c of the fitting groove 11a is heated uniformly, softened and melted and when the end 12a of the adjuster cylinder 12 is inserted into the fitting groove 11a from the upper part, the inner and the ouer wall surface 12b, 12c of the joint 12a of the adjuster cylinder 12 are welded in one body to the inner and the outer wall surface 11b, 11c of the fitting groove 11a and joined strongly.

Description

【発明の詳細な説明】 本発明は２合成樹脂成型体を簡便な方法で熱溶着させて
強固に接続する方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for firmly connecting two synthetic resin molded bodies by thermally welding them together using a simple method.

一般に、排水ますなどの合成樹脂成型体の接続部を接続

水性のある接着剤を一方の接続部に接着して行うことが
通例となっている。In general, the conventional method for connecting joints of synthetic resin molded bodies such as drainage basins is to glue one joint with a waterproof adhesive such as butyl rubber. .

しかし、このような方法は、比較的接着力が弱いため接
続部を強く接合させることが期待できず、しかも接着剤
が即座に固化しないためにその作業性を低下させる要因
にもなっている。However, in this method, the adhesive force is relatively weak, so it cannot be expected to strongly bond the connection parts, and furthermore, the adhesive does not solidify immediately, which is a factor that reduces the workability.

特に、近年下水処理に広く使用されるようになったポリ

で、ます本体とアジャスター筒体とを接続したものを寒
冷地などに埋設した場合には、凍結時に生じる凍上刃に
よってアジャスター筒体が持ち上げられて接続部に隙間
を生じてしまうなどの問題を生じている。In particular, if we take as an example the polypropylene drainage basin that has become widely used in sewage treatment in recent years, if the basin body and adjuster cylinder are connected in this way and buried in a cold region, etc. However, there are problems in that the adjuster cylinder is lifted by the frost-heaving blade that occurs when it freezes, creating a gap at the connection part.

本発明は、かかる事情に鑑みてなされたもので、接合力
の大きい熱溶着による接続方法を簡便に行える合成樹脂
成型体の接続方法を提供することを目的としたものであ
る。The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a method for connecting synthetic resin molded bodies that can easily be connected by heat welding, which has a large bonding force.

以下に、添付図面と共にその好適な実施例を詳説する。Hereinafter, preferred embodiments will be described in detail with reference to the accompanying drawings.

まづ、第１図を参照して第一の実施例について説明する
。First, a first embodiment will be described with reference to FIG.

本例は、合成樹脂成型体の接続部にニクロム線などの電
熱体を直接巻装して接続部を溶着するものである。In this example, an electric heating element such as a nichrome wire is directly wound around the connection part of a synthetic resin molded body, and the connection part is welded.

な素材より成るアジャスター筒体１２の接続部である端
部１２ａが嵌合されるようになっている。As a synthetic resin molded body, a drainage basin 1 is used, which is constructed by combining a basin main body 11 made of a strong polypropylene low-foamed material and an adjuster cylinder 12. An end portion 12a, which is a connection portion, of an adjuster cylinder 12 made of a similar material is fitted into the groove 11a.

ニクロム線２は、コンセント３の一方のコード線３１に

ト３の他方のコード線３２に結線されている。The nichrome wire 2 is connected to one cord wire 31 of the outlet 3, and is wound spirally from above to below the inner wall surface 11b of the fitting groove 11a. The wire passes through the outer wall surface 11C to reach the lower part of the outer wall surface 11C, and further ascends the outer wall surface 11C in a spiral shape to be connected to the other cord wire 32 of the outlet 3.

が嵌合溝１１８の内、外壁面１１ｂ、ＩＩＣに溶着一体
化して強固に接続される。According to such a configuration, when the receptacle 3 is connected to a power source and the nichrome wire 2 is heated with electricity, the fitting groove 11
8, the outer wall surfaces 11b and IIC are uniformly heated and softened and melted, so that the adjuster cylinder 1
2 into the fitting groove 11a from above (by pressing by hand or applying pressure), the inner and outer wall surfaces 12b and 12c of the connecting portion 12a of the adjuster cylinder 12.
is integrally welded to the outer wall surface 11b and IIC inside the fitting groove 118 and is firmly connected.

なお、接続部より外方に突出したニクロム線の突出端は
後に切除すればよい。Note that the protruding end of the nichrome wire protruding outward from the connecting portion may be cut off later.

表面のみを局部的に加熱して、他の部分に変形を生じさ
せないことが望ましい。It goes without saying that the energizing time of the nichrome wire 2 and the wire diameter of the nichrome wire are determined appropriately depending on the adjuster cylinder and the main body of the nichrome wire, but in any case, only the surface of the connection part is locally It is desirable that heating does not cause deformation in other parts.

此の点、本例に於ける排水まずでは、強靭なポリプロピ
レンの低発泡体を想定しているため、加熱部の表面のみ

である。In this regard, since the drainage in this example is assumed to be a tough polypropylene low-foamed material, only the surface of the heated part is melted and other parts are less likely to be deformed, which is extremely beneficial.

しかし、本発明の適用可能な合成樹脂成型体としてはこ
のようなものに限られず、ポリエチレン。However, the synthetic resin molded bodies to which the present invention can be applied are not limited to these, but include polyethylene.

ポリ塩化ビニル、ポリスチレンなとの熱溶着の可能な熱
可塑性の成型体であればよい。Any thermoplastic molded body that can be thermally welded to polyvinyl chloride, polystyrene, etc. may be used.

次に、第二の実施例について説明する。Next, a second embodiment will be described.

１ｂ、２１ｂで挟装して形成されている。The electric heating body in this example can be roughly divided into two types, and the electric heating body 21 formed into a tape shape has a plurality of electric heating bodies 21 arranged in parallel at appropriate intervals, as shown in FIG. Two sheet bodies 2 made of true melt adhesive are made by connecting heating wire segments 21a- at each end and connecting them in series.
It is sandwiched between 1b and 21b.

The adjuster cylinder 12 is fitted into the fitting groove 112 of No. 1, and heated with electricity to thermally weld the adjuster cylinder 12 to the main body 11.

The nichrome wires 23a are formed by connecting their ends to each other and sandwiching them between ring-shaped sheet bodies 22b, 22b, 23b, and 23b made of hot melt adhesive.

一体化すればよい。When using such electric heating elements 22 and 23, first fit them into the fitting groove 112 of the main body 11, and then
As shown in the figure, the adjuster cylinder 12 is inserted into the fitting groove 11a.
The end portion 12a of the main body 11 and the fitting groove 11a of the main body 11 may be integrated by heat welding.
