Description

[Detailed Description of the Invention] The present invention relates to improving the water side structure at the joints of unit panels constituting the walls, floors, etc. of a prefabricated tank.

In the case of a water storage tank formed by joining multiple unit panels and assembling them on the tank wall, floor, etc., the joints of the individual panels are immersed in water, and in addition, in this type of tank, Since many of them are designed to store relatively large amounts of water, the water pressure applied to these joints is usually high.

Therefore, as shown in FIGS. 1 and 2, the space 5 created by the meeting of the corners of each unit panel.
If the pipes are not completely sealed, there is an extremely high risk of water leakage.

The present invention mainly relates to improving the water side effect of the space 5 in this type of tethered tank, and will be explained next with reference to the embodiments shown in the drawings.

1 and 2 are a plan view and a partial plan view schematically showing the structure of a conventional joint section.

As shown in Figure 2, the space 5 (hereinafter referred to as corner space) created by the meeting of the corners when four unit panels are butt-jointed can be completely covered by the band packing interposed between each unit panel. It is difficult to stab closely.

In view of this problem, in this invention, this corner space 5 is replaced by a strip-shaped flexible packing l covered with each unit panel 1, 2, 3, and 4.
a, 2at, 3a, and 4a, and at least one of the gaskets is provided with a protrusion so that the corner space 5 is filled with the protrusion.

An embodiment of the present invention will be explained based on FIGS. 3 to 5.

That is, FIG. 3 shows band-shaped flexible packing la, 2a.

This figure shows the state after compression when the protrusions 2bs3b are provided at positions that fill the corner spaces 5 of 2a and 3a among 3a and 4a, but the protrusions 2a and 3b fill the corner spaces 5. The structure is designed to reliably prevent water leakage from this part.

4 and 5 show the case where the corner space 7 is opened by two unit panels and a connecting plate 6 that connects both panels. The figures show the prior art.

In FIG. 4, unit panels 1 and 2 are covered with belt-shaped flexible packings 1a and 2a, and a connecting plate 6 is provided with projections 6b.
A band-shaped flexible packing 6a having a diameter is covered.

By tightening the bolts 8 that fasten between the unit panels 1 and 2 and between the unit panels 1 and 2 and the connecting plate 6, the band-shaped flexible packings 1a, 2a, and 6a are compressed, and the protrusions 6b penetrate the corner spaces 7. Become.

However, in the prior art shown in FIG. 5, the opening of the corner space I is performed by the band-shaped flexible packing la, 5a and the one end face 9 of the unit panel corner that does not touch the space, so that the three Compared to the case where the space T is opened by band-like flexible five-pieces, the completeness of the space T due to the mutual compression of the gaskets when the unit panels are fastened with bolts is inevitably incomplete.

As described above, when a plurality of unit panels are joined together and assembled on the wall or floor of a prefabricated tank, the space created by the meeting of the corners of each unit panel is covered by each unit panel. A structure of a unit panel joint in a prefabricated tank, characterized in that it is surrounded only by a strip-shaped flexible packing, and at least one of the packing is provided with a protrusion so that the protrusion fills the space. According to this method, the following practical benefits can be obtained and it is very effective; Namely, in the case of the present invention, the above-mentioned corner space is surrounded only by a band-shaped flexible packing layer that is extremely easily deformed by external force, so that the unit Due to the compressive deformation of the packing that occurs when the panels are joined, the protrusions of the band-shaped flexible packing easily close this space.

Therefore, the water side effect of the corner space in the prefabricated tank, which has been desired to be improved in the past, can be significantly achieved.
