Description

[Detailed Description of the Invention] The present invention mainly relates to an improvement of a rim material for mounting a lid panel, which is attached to the rim of a sewage treatment tank.

Conventionally, a lid panel holding mechanism as shown in FIG. 1 has been generally used as an edge material for mounting a lid panel on a sewage treatment tank or a ditch.

That is, as shown in Fig. 1, the edge material a that is attached to the outer periphery of the tank or groove and supports the end of the lid panel b is integrally formed with a triangular hollow part with a slope on the outside to prevent tripping, and from this to the inside. The extending lid panel holder has a structure consisting of a plate.

In this case, the odor easily escapes from the gap between the lid panel b and the edge material a and the gap between the edge material a and the installation surface 1, which is insufficient for the purpose of odor control, and the lid panel b is made of light metal with light weight. When doing so, there is also the problem that they may be blown away by strong winds.

The present invention provides an improved edge material for mounting a lid panel for the purpose of improving the odor-proofing properties and anti-wind properties of the edge material of a sewage treatment tank.

The edge material according to the present invention is provided with a rising part on which the end surfaces of the lid panel abut, and a horizontal locking surface is formed on the upper end side of this rising part to prevent the lid panel from floating on the horizontal locking surface. In addition to having a structure in which a tool can be attached, a lid panel holder plate is installed on the lower end side of the rising portion and extends along the lower part of the lid panel, and backing insertion grooves are integrally formed on the upper and lower surfaces of this plate, respectively. By forming
The unique feature of this product is that it has the dual effects of deodorizing and preventing the lid from floating in one rim material.

The device of this invention is mainly applied to the edge material for mounting the lid panel of a sewage treatment tank installed outdoors, and is also suitable for use with lid panels made of light metals such as aluminum because it has both odor prevention and anti-floating effects. is particularly effectively applied.

The edge material of the structure according to the present invention can be integrally formed and manufactured by extrusion processing of aluminum and aluminum alloy.

The present invention will be explained below according to embodiments shown in the drawings.

Embodiment 1 (Fig. 2) 1 corresponds to the upper surface of the outer periphery of the sewage treatment tank or groove, and corresponds to the installation surface of the edging material 2. In this example, the lid panel 3 is placed on this installation surface 1. be.

The edge member 2 has a substantially trapezoidal hollow shape with an inclined surface 4 on the outside, and a rising portion 5 is formed on the inside thereof with which the end face of the lid panel 3 is abutted.

A horizontal locking surface 6 is formed on the upper end side of the rising portion 5, and a plate-shaped lid panel floating preventer 7 is attached to this horizontal locking surface 6 with screws 8 so as to suppress the top surface of the lid panel 3. has been done.

A lid panel holder plate 9 is provided on the lower end side of the rising portion 5 and extends along the lower side of the lid panel 3. Furthermore, this lid panel holder has an upwardly directed backing insertion groove 10 formed on the upper surface of the plate 9. hold the deodorizing backing 11 and bring it into contact with the lower surface of the lid panel 3, and then
It has a deodorizing effect between the

Furthermore, in the above-mentioned lid panel holder, the plate 9 extends along the installation surface 1, and the deodorizing backing 13 is inserted into the other downward backing insertion groove 12 formed in the plate 9 and installed. By bringing it into contact with surface 1, edge material 2
It also has a deodorizing effect between the installation surface 1 and the installation surface 1.

Embodiment 2 (Figure 3) This example is another embodiment in which the lid 3 is placed at a lower level than the installation surface 1. The lid 3 is installed so that its upper surface is approximately at the same level as the installation surface 1. It will be done.

In this case, the edge member 2 is the same as in Example 1 except that it consists of a horizontal locking surface 6, a rising portion 5, and a plate 9 for the lid panel holder, and does not have an inclined surface or a hollow portion.

Embodiment 3 (FIG. 4) This embodiment is another embodiment in which M3 is mounted at a level considerably higher than installation surface 1.

The edge material 2 has a hollow plate 9, which extends along the lower part of the lid 3, and has a certain arbitrary thickness so that the mounting position of the lid 3 is raised. The backing insertion groove 10 and the deodorizing backing 11 inserted into the hollow lid panel holder are on the upper surface of the plate 9, and the backing insertion groove 12 on the installation surface side and the deodorizing backing 13 inserted into the hollow plate 9, respectively.

The rest is the same as in the first embodiment.

As described above, in the edge material according to the present invention, the space between the lid panel surface and the installation surface is sufficiently odor-proofed by the dedicated odor-preventing backing, and odor can be effectively confined in the processing tank.

In addition, the upper part of the edge material has a horizontal locking surface for attaching the lid panel lifting prevention device, so by locking the lifting prevention device to the edge material with screws, etc., the lid panel can be held down from the top surface. The lid panel can be effectively prevented from being blown away by strong winds.
