Field of the Invention The present invention relates to a septic tank in which a collar formed around a wall member is fitted to a peripheral portion of a tubular septic tank body to partition an inner space of the septic tank body in a longitudinal direction thereof. It relates to an assembling method.

Description of the Related Art Conventionally, in such a method of assembling a septic tank, a thermosetting resin such as unsaturated polyester is impregnated over the collar portion and the septic tank body to join the wall member to the septic tank body. The so-called mat joining, in which a glass mat is overlaid and bonded, has been performed.

全周にわたって確実に接着できる保障が得られない。However, in order to perform the mat joining, it is necessary to sand the mating surface facing the mat in advance to make it rough, which is not only time-consuming but also sanding. In the case of, for example, FRP
There is a problem that dusts such as plastics and glass fibers, which are materials of the mat, are generated, which may impair the health of workers, and that the glass fibers of the mat itself are not desirable in the working environment. In addition, since the glass mat before curing is soft, it must be arranged over the entire circumference while pressing the glass mat in order over each part, which takes time and effort, and also takes time and effort to cure it. However, there is a disadvantage that workability is poor because of the necessity. As one of the countermeasures, it is conceivable to apply an adhesive to one of the fitting surfaces of the septic tank main body and the wall member, and then fit and bond the two together. There is a possibility that the applied adhesive may be peeled off from the fitting surface at the time of fitting, so that there is no guarantee that the adhesive can be securely bonded over the entire circumference.

For example, on the septic tank main body side, for example, two spacers having appropriate elasticity are attached in advance in the circumferential direction in parallel, for example, and the septic tank main body and the wall member are fitted in a state where an adhesive is disposed between both spacers. At the time of fitting, the fitting can be performed while securing a gap between the peripheral portion of the septic tank main body and the brim portion of the wall member, so that the adhesive can be prevented from being scraped off. After the fitting, the flange portion of the wall member and the peripheral portion of the main body are fastened to each other by a fastener such as a bolt or a rivet, and the two are pressed against each other, so that the two can be securely joined via the adhesive. it can.
Also, compared to the conventional method of assembling a septic tank that had to rely on mat joining, in the case of the present application, there is no problem in the working environment due to the glass fibers of the glass mat, and the joining surface is roughened by sanding. Since it is not necessary to form a surface, the problem on the working environment caused by dust such as plastic and glass fiber, which are materials of the wall member and the septic tank main body, is also solved. Also, it takes less time and effort than necessary for sanding and attaching and curing the glass mat.

せることができる。Hereinafter, a method of assembling a septic tank according to the present invention will be described.
A method of joining the lid member B to the septic tank main body 2 to partition the internal space of the main body from the external space will be described. FIG. 2 is an enlarged cross-sectional view of the joint between the lid member B and the septic tank main body 2 in FIG. Elastic band-shaped and ring-shaped spacers S arranged in parallel in the entire circumferential direction in the circumferential direction
And an adhesive C disposed between the spacers S,
The flange portion F of the cover member B is externally fitted to the septic tank main body 2 and is joined by pressing with a bolt V passing therethrough. The procedure leading to the bonding state shown in FIG. 2 may be, for example, as follows. The procedure will be described with reference to FIG. 3. Before fitting the lid member B to the septic tank main body 2, first, as shown in FIG. Two spacers are attached in parallel over the entire circumference, and then
When the lid member B is fitted to the septic tank main body 2 as shown in (c) in a state in which the adhesive C is arranged between the two spacers as shown in (b), the septic tank main body 2 is fitted at the time of fitting. Can be fitted while ensuring a gap between the peripheral portion of the cover member B and the flange portion F of the cover member B, so that the adhesive C works effectively without being scraped off. After mating in this way,
As shown in (d), the flange portion F of the wall member B and the septic tank main body 2 are fastened to each other by bolts V and pressed against each other, so that the two members have good sealing properties over the entire circumference via the adhesive C. It can be surely joined while maintaining the above. The adhesive C also serves as a seal. In particular, when the flange portion F and the septic tank main body 2 are pressed against each other, the adhesive C penetrates into and fills the gap around the bolt V, so that liquid leakage from the bolt hole can be prevented. The spacer S can also serve as a seal.

とができる。Next, a case where the partition plate A is attached to the septic tank main body 2 will be described with reference to FIG. (A) of FIG.
As shown in the longitudinal sectional side view of the main part, an elastic band-shaped spacer S is arranged in the circumferential direction on the inner fitting surface of the septic tank main body 2, and an adhesive C is arranged close to one side along one side of the spacer. Agent C
On the other hand, from the side opposite to the spacer S, a flange portion F formed into a shape having an L-shape in a sectional view around the partition plate A is internally fitted, and is pushed in so as to ride on the spacer S.
As shown in (b), since the adhesive is pushed into the gap between the collar portion F and the septic tank main body, the two are pressed into contact with each other via the adhesive and are securely joined. By this method, the anaerobic filter bed tank N and the contact aeration tank E could be easily partitioned. The spacer may be ring-shaped over the entire circumference, but may be divided into several strip-shaped segments. Note that a configuration in which the adhesive C is disposed on both sides in the width direction of the spacer S is also possible. As the adhesive C, an epoxy-based, urethane-based, acrylic-based adhesive, or the like can be used.
