Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a structure for attaching a contact material in a septic tank.

[Background Art] Contact materials for septic tanks are generally made of corrugated polyvinyl chloride, and a plurality of these contact materials are stacked together to form a contact material block, which is installed in a septic tank. Conventionally, when installing the contact material, the fifth
6, the contact material 1 is stacked so that the boss portions 2 are in contact with each other and a gap is formed between them, and the boss portions 2 are welded 3 to form a contact material block 4. , the contact material block 4 is placed inside the septic tank 5, and ribs 7 are provided on the partition plate 6 or outer wall of the septic tank 5.
It is fixed and attached to. In such a conventional example, only the contact material 1 at both ends is supported by the rib 7, and the other parts are supported by the boss portion 2 of the contact material 1.
It is held only by adhesive 3, and is weak against force from above.
Further, if the adhesive 3 of the boss portion 2 comes off, the contact members 1 come apart and fall.

[Purpose of the invention] The present invention has been made in view of the above points, and the purpose of the invention is to securely hold the contact material in the holding frame and to ensure that it can be installed inside the septic tank. The present invention provides a contact material mounting structure for a septic tank.

[Disclosure of the invention] The contact material mounting structure of the septic tank of the present invention is constructed by stacking a plurality of corrugated contact materials 1 such that the boss portions 2 are in contact with each other and a gap is formed between them to form a contact material block 4. A holding frame 8 is fitted to at least one of the upper end and the lower end of the contact material block 4, and the contact material block 4 held by the holding frame 8 is placed inside the septic tank 5 and attached to the partition plate 6 and outer wall of the septic tank 5. The structure is fixed to a rib 7 formed in the shape of a rib 7, and the drawbacks of the conventional example are solved by configuring it as described above.

The present invention will be explained in detail below using examples.

1 is a contact material made of synthetic resin such as polyvinyl chloride and formed into a corrugated plate shape, and a plurality of contact materials 1 are stacked and brought into contact so that the boss portions 2 are in contact with each other and there is a gap between them. A material block 4 is formed. The boss portions 2 of the contact material 1 of the contact material block 4 do not necessarily need to be bonded together as in the conventional case. Reference numeral 8 denotes a holding frame having an opening 10 for water passage, and locking pieces 9 are hung from both ends. This holding frame 8 is arranged above and below the contact material block 4, and is fitted onto the top and bottom of the contact material block 4, so that the locking pieces 9 are locked to the contact materials 1 at both ends of the contact material block 4. Although it is preferable that the holding frame 8 be provided on both the upper and lower sides, it may be provided only on the upper side or only on the lower side. In other words, floating can be prevented when only on the top, falling can be prevented when only on the bottom, and floating and falling can be prevented when both are on the top and bottom. The contact material block 4 held by the holding frame 8 in this manner is placed inside the septic tank 5, and the top and bottom of the contact material block 4 are locked to the partition plate 6 of the septic tank 5 and ribs 7 provided at the top and bottom of the outer wall, respectively. It is installed in the septic tank 5. FIG. 3 shows another embodiment of the holding frame 8, in which locking pieces 9 are hung from the four circumferences of the holding frame 8. With this configuration, it can be held more reliably. In addition, since the contact material block 4 is held by the holding frame 8, there is no need to glue the boss parts 2 together, and there is no need to store them in a stacked manner as shown in Fig. 4a, and as shown in Fig. 4b. As shown, they can be stored on top of each other without leaving any gaps between them. This requires less inventory space.

[Effects of the invention] As described above, the present invention forms a contact material block by stacking a plurality of corrugated contact materials such that the boss portions are in contact with each other and a gap is formed between them. Of course, it is possible to reliably form a gap between the contact materials by the abutment of the boss parts without intervening a spacer between the contact materials. The holding frame was arranged, and the locking pieces vertically installed at both ends of the holding frame were locked to the contact members at both ends of the contact material block, and the contact material block was held by the holding frame, so that the contact material block was not attached to the holding frame. It is possible to reliably hold each of the contact materials in the septic tank and to securely install the contact materials in the septic tank.Moreover, a holding frame is placed on at least one of the upper end or the lower end of the contact material block, and the locking piece is attached to the contact material. The contact material block can be easily held in a holding frame with a simple structure by simply locking it to the contact material block, and the contact material block can also be easily attached and removed when replacing the contact material. Moreover, since it can be held simply by fitting the holding frame over it, it can be easily constructed without requiring any man-hours for assembly.Furthermore, the contact materials do not necessarily need to be glued together as in the past, making assembly even easier. It is what it is.
