Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a septic tank in which a flange portion formed around a wall member is joined to a peripheral portion of a cylindrical septic tank main body to partition an inner space of the septic tank main body in a longitudinal direction thereof. Assembling method

[0002]

2. Description of the Related Art Conventionally, in assembling a septic tank of this type, in order to join the wall member with the collar portion to the septic tank main body, a thermosetting resin such as unsaturated polyester is impregnated between the collar portion and the septic tank main body. The so-called mat joining was performed by overlaying and bonding the glass mat.

[0003]

However, in order to mat-bond the wall member to the septic tank body, it is necessary to sand the mating surface facing the mat in advance to make it rough, which is troublesome. Not only that, when sanding, dust such as plastic or glass fiber, which is the material of FRP, may be generated, which may impair the health of the operator, and the glass fiber of the mat itself is not desirable in the working environment. there were. In addition, since the glass mat before curing is soft, it must be placed over the entire circumference while pressing it in order over each part, which takes time and labor, and it takes time and time to cure it. As a result, it has the drawback of poor workability.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to assemble a septic tank having good workability, which solves the above-mentioned problems in the working environment and can easily and reliably join the wall member to the septic tank main body in a short time. To provide a method.

[0005]

The means for assembling a septic tank according to the present invention for achieving this object is characterized in that a molding member for joining along the longitudinal direction of a collar portion formed around a wall member is The brim portion and the septic tank main body are arranged, and the joining molding member is bonded to each of the brim portion and the septic tank main body with an adhesive.

[0006]

By arranging the molding member for joining along the longitudinal direction of the collar portion of the wall member and over the collar portion and the septic tank main body, the collar portion and the septic tank main body are made uniform at the same time with an adhesive over a wide area. Because it can be pressed
The wall member can be efficiently bonded to the septic tank main body through the bonding molding member, and the glass mat does not have to be used as in the conventional case. In addition, since it was necessary to make the joint surface with the glass mat rough by sanding, dust such as plastic or glass fiber, which is the material of the wall member or the main body of the septic tank, is generated, which impairs the health of workers. The problem in the conventional work environment that there is a risk is also solved.

[0007]

That is, the problem of working environment associated with the conventional method for assembling the septic tank is solved, and it is possible to easily and quickly.
Further, it is possible to provide a method for assembling a septic tank, which is capable of reliably joining the wall member to the septic tank main body to partition the internal space of the septic tank main body and having good workability.

[0008]

Embodiments of the method for assembling a septic tank according to the present invention will be described below with reference to the drawings. First, the outline of the structure of the septic tank in the embodiment will be described. As shown in the cross-sectional front view drawing of the septic tank in (a) of FIG. 1 and the vertical side view in (b), the septic tank 1 is located near the longitudinal center of the cylindrical main body 2 having an oval cross section. A partition plate A serving as a wall member 3 is provided, whereby the septic tank main body 2 is partitioned in the longitudinal direction to be divided into an anaerobic filter bed tank N and an aeration filter bed tank E, and both ends of the septic tank body 2 are bottomed cylinders. A lid member B, which is a wall member 3 having a rectangular shape, is externally fitted to partition the external space.

A method for assembling the septic tank according to the present invention will be described below in which the partition plate A is joined to the septic tank main body 2 to partition the internal space of the septic tank main body 2 into the anaerobic filter bed tank N and the contact aeration tank E. . FIG. 2 shows an enlarged cross section of the joint between the partition plate A and the septic tank main body 2 in FIG. As shown in FIGS. 1 and 2, the partition plate A is arranged at a predetermined position of the septic tank main body 2 at a right angle to the longitudinal direction thereof.
Collar portion F formed in an L-like shape in a sectional view of the surroundings
After being fitted in a state of abutting on the inner surface of the septic tank body, the joining molding member J along the longitudinal direction of the collar portion F is attached to the collar portion F.
By arranging it over the septic tank main body 2 and adhering the joining molding member J to each of the brim F and the septic tank main body 2 via the adhesive C previously applied to the joining molding member side. It was possible to partition the anaerobic filter bed tank N and the contact aeration tank E. The molding member J for joining may be formed in a ring shape over the entire inner circumference of the septic tank main body, but it is easier to work if this ring is divided into several arc-shaped segments. In the case of using the joining molding member J formed in one ring shape, the brim portion F of the partition plate A is previously prepared.
It is advisable to apply the adhesive C on both the side and the septic tank main body side. When the bottomed tubular lid member B is attached to the septic tank main body 2 as well, as shown in the longitudinal cross-sectional view of the main part in FIG. By adhering the brim F of B to the septic tank main body 2, the lid member B could be reliably joined to the septic tank main body 2. As the adhesive C, an epoxy-based, urethane-based, acrylic-based or other adhesive can be used. By the method described above, a septic tank having sufficient strength and having no liquid leakage could be efficiently assembled.

It should be noted that reference numerals are added to the claims for convenience of comparison with the drawings, but the present invention is not limited to the structures of the accompanying drawings by the entry.
