Description

[Detailed description of the invention] This invention relates to the improvement of wastewater treatment tanks that are installed on the floors of kitchens, gas stations, etc. and are used to separate and remove garbage and oil components from wastewater. The purpose is to enable molding of FRP, etc., to facilitate waterproofing construction, and to ensure bonding and fixing to concrete floors.

The features of this invention for achieving the above object are that an outward flange is integrally molded around the entire circumference of the upper opening edge of the upper opening type processing tank body, and a portion of the upper surface of the outward flange near the opening edge is A raised part having an upwardly convex cross section is formed continuously over the entire circumference of the outward flange, and an embedded fixing support member is provided on the lower surface of the wing part that extends further to the outer periphery than the raised part of the outward flange. They are located at points installed at intervals in the circumferential direction of the flange.

Hereinafter, embodiments of this invention will be described based on the drawings.

In the drawing, reference numeral 1 denotes a processing tank body made of plastic material such as FRP into a box shape with an upward opening, and an outwardly extending outward flange 2 is integrally molded around the entire circumference of this upper opening edge 1a. It has been done. The outward flange 2 in the illustrated example is integrally molded so as to be inclined at an α angle with respect to the horizontal plane S.
Further, the opening edge 1a on the upper surface of the outward flange 2
A raised part 3 having an upwardly convex cross section is formed continuously over the entire circumference of the flange 2 in a region near the raised part 3 of the flange 2, and a wing part 2a extending to the outer periphery of the raised part 3 of the flange 2. There are several wires on the top surface (two wires in the figure).
A groove 4 is formed all around the flange 2. Reference numeral 5 denotes embedded fixing supports, which are attached to the lower surface of the wing part 2a of the outward flange 2 using round head bolts 6 and nuts 7, and are arranged in rows at intervals in the circumferential direction of the outward flange 2. Ru. This support member 5 is rotatable around the bolt 6 when the nut 7 is loosened, as shown in FIG.
The external dimensions are such that the blade portion 2a is housed inside the outer peripheral edge of the blade portion 2a. 8 is the processing tank body 1
This is a cylinder through which a drain pipe passes and is fixedly fixed to the left and right side walls 9 and 10, respectively. In addition, the size of the wastewater treatment tank with the above configuration varies depending on its capacity.
Medium size, each dimension of length x width x height is 1150mm x
It is 650mm x 600mm. In addition, the raised portion 3 and the groove 4
To show an example of each dimension, the raised part 3 has a height of 20 mm and a width of 30 mm.
mm, and the groove 4 has a depth of 3 mm and a width of 5 mm.

The wastewater treatment tank configured in this way has a raised part 3 around the entire circumference of the outward flange 2, so even when high heat is generated during FRP molding and drying, the raised part 3 can prevent distortion. It is possible to easily obtain a wastewater treatment tank with a predetermined size and shape.

The above-mentioned wastewater treatment tank houses a basket (not shown) for separating and removing garbage and oil components in the wastewater, and is either embedded in the floor of a kitchen or the like, or installed in a suspended manner on the floor above. However, in this installation, as shown in FIG. 8, the treatment tank body 1 is fitted into the opening 12 of the concrete floor structure material 11, and the outward flange 2 is placed so as to be hooked onto the upper surface of the outer periphery of the opening 12. , the bent end portion 5a of each embedded fixing support member 5 is connected to the concrete floor structure member 11.
It is embedded and fixed in. By embedding and fixing the embedded fixing support material 5, even an FRP wastewater treatment tank that is not compatible with concrete can be securely fixed to the concrete floor structure material 11, and this fixed state can be firmly maintained. It can be done.
In particular, the outward flange 2 of the processing tank body 1 has an opening edge 1
Although the part near point a is reinforced by the raised part 3, the thin wing part 2a extending from the raised part 3 is forced to be relatively weak. After fixing, the wing part 2a is integrated with the floor structure material 11 via the support material 5, and becomes extremely strong.

In addition, during this installation, in order to improve water drainage between the overlapping surfaces of the outward flange 2 and the concrete floor structure material 11, a waterproof material 13 such as asphalt is applied from the upper surface of the floor structure material 11 to the outward flange 2.
During this waterproofing work, a raised part 3 is formed with an upwardly convex cross section over the entire upper surface of the outward flange 2, so that the raised part 3 can be used to coat asphalt, etc. It is possible to prevent the material 13 from flowing into the wastewater treatment tank, and this waterproofing work is easily performed. Note that, as shown in the illustrated example, when a groove 4 is formed on the upper surface of the outward flange 2, a waterproof material 13 such as asphalt is inserted into the groove 4.
This allows the outer flange 2 and the waterproofing material 13 to be more integrally bonded to each other, thereby making the waterproofing effect more complete. In addition, if round-headed bolts are used as the mounting bolts 6 for the embedded fixing support 5, the corners of the head may crack the waterproofing material 13 and cause water leakage, as in the case of hexagonal-headed bolts, for example. This eliminates the problem of causing water damage, and makes it possible to improve waterproofing.

A waterproof protection mortar or cinder concrete 14 is further applied on top of the waterproof material 13, but in this case, the portion of the mortar or cinder concrete 14 that corresponds to the upper part of the waste water treatment tank must be opened. Waterproof material 13
Since the uppermost apex 3a of the raised portion 3 exposed from the end of the opening serves as a guide for constructing the opening, the construction is easily performed.

After this construction, dew condensation may occur between the waterproof protective mortar or cinder concrete 14 and the waterproof material 13, but this condensation is caused by the α angle formed by the outward flange 2 and the horizontal surface S as shown in the figure. The resulting dew can flow into the wastewater treatment tank along the inclined surface of the waterproof material 13, thereby preventing the condensation from flowing out of the wastewater treatment tank.

As is clear from the above embodiments, the wastewater treatment tank of this invention has a protrusion 3 with an upwardly convex cross section continuously formed on the upper surface of the outward flange 2 over the entire circumference of the flange 2, so it is lightweight. Even if this is manufactured by FRP molding for the purpose of improving workability and increasing strength, it is possible to obtain a good wastewater treatment tank without distortion, and when asphalt or other waterproofing material is installed, the ridges 3 of the waterproofing material 13 will flow. It can be effectively used as a stopper, making it easier to install waterproofing materials, and is also strong against concrete floors due to the plurality of embedded fixing supports 5 installed at intervals around the entire circumference of the outward flange 2. It is extremely useful as a wastewater treatment tank for wastewater discharged from kitchens, gas stations, etc., as it can be easily fixed and fixed.

Particularly, in the present invention, by providing the raised portion 3 in the vicinity of the opening edge 1a of the processing tank main body of the outward flange 2, the flange 2 is reinforced, and the strength is particularly improved at the root portion of the flange 2 relative to the processing tank main body 1. Contribute to On the other hand, although the flange wing part 2a extending to the outer periphery beyond the raised part 3 is thin and fragile, an embedded fixing support member 5 is attached to the lower surface of this wing part 2a. After the tank body 1 is installed, the blade portion 2a is integrated with the floor structure material 11 via the supporting material 5, so that the thin plate-like blade portion 2a does not separate from the floor structure material 11. Of course,
Even if there is a gap between the wing part 2a and the floor structure material 11 due to poor installation, the wing part 2a
A is strong, with no cracks or breakage caused by loads from above.
