Description

[Detailed Description of the Invention] The present invention relates to a structure in which a stop plate is attached to a stepped joint where unit panels constituting a liquid storage tank are joined in a stepped manner.

As shown in FIG. 1, unit panels constituting the bottom of the liquid storage tank include a unit panel 1 with a slope in consideration of drainage and a half-size unit panel 2 without a slope. That is, the sloped unit panel 1 extends from the four side edges of the back surface of the square plate 3 to the flange portion 4.
is provided protrudingly, and the other side edges 3b, 3b on the front side of the square plate 3 excluding the opposing side edges 3a, 3a are in a sloped state (for example, the lower edge 4a of the flange portion 4).
The square plate 3 is formed with an inclination of 1/100 with respect to the virtual plane formed by the square plate 3, and furthermore, the center of the square plate 3 is made to protrude in a mountain shape as necessary to increase the section modulus. Further, the half-size unit panel 2 has flanges 6 protruding from the four side edges of the back surface of a rectangular square plate 5, and a portion near the center of the square plate 5 is made to protrude in a mountain shape as necessary. The unit panels 1 and 2
is used as a unit panel constituting the partition wall 7 because of its high water pressure resistance.

Then, at the joint portion of the unit panel 1 and the unit panel 2 constituting the partition wall 7, an uneven joint portion A is generated on the surface side of the square plate. By the way, when reinforcing tension bars 9, 9 are hung between the outer wall 8 facing the partition wall 7 and the partition wall 7, the edge 3a of the unit panel 1 forming the uneven joint A and the unit panel 2 Reinforcement tension bars 9, 9 are attached to the edge 5a of the
When it is necessary to connect the bolt-formed ends 9a, 9a, a bent contact plate 8 bent to correspond to the uneven joint part A is brought into contact with the surface side of the rectangular plate, and as shown in FIG. , one end of the tension bars 9, 9 is inserted into the insertion holes 10a, 1 of the bending plate 10.
After being inserted into the insertion holes 2a' and 5a' of the unit panels 1 and 2, they were connected by tightening and fixing them with nuts 11, 11, . . . . Therefore, in the past, an expensive bending plate 10 with additional bending processing costs was required, and a standardized flat plate 1 that abutted on the outer wall 8 was required.
It is necessary to prepare two types of bending plates 10 and 10 in advance, which causes troublesome drawbacks in managing the plates.

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks, the present invention aims to provide a structure for attaching a contact plate to an uneven joint of a unit panel.

The gist of this invention is to join unit panels together so that the surfaces of adjacent rectangular panels are at different levels, and to place a backing plate on the surface of both panels that straddles the adjacent edges of the surfaces of both panels. In a contact plate mounting structure in which bolts are inserted into insertion holes drilled in the contact plate and each square plate, and the contact plates are fixed onto both shape plates by nuts screwed onto the bolts, the contact plate is fixed to the flat plate. A distance in which a bolt insertion hole is formed is interposed between the back surface of the contact plate and the edge of the surface of the rectangular plate constituting the entrance side of the stepped joint.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a structure for attaching a backing plate to an uneven joint of a unit panel according to the present invention (hereinafter referred to as the proposed structure) will be described based on an embodiment shown in the drawings. FIG. 3 is a sectional view showing an embodiment of the proposed structure. The main improvement of the proposed structure is that the backing plate is a flat backing plate 12.
In addition, a distance 13 is interposed between the surface edge 5a of the unit panel 2 constituting the entrance side of the stepped joint A and the flat plate 12. The destante 13 has a bolt insertion hole 13 for inserting the bolt forming end 9a of the reinforcing tension bar 9.
A is drilled. Packing 14 is provided between the distance 13 and the flat plate 12 and/or between the distance 13 and the unit panel edge 5a as required.
is interposed. 15 in the figure is the bolt insertion hole 12
This is a packing that covers the opening of the insertion bolt 9a and the insertion bolt 9a.

Fig. 4 shows an embodiment of another aspect of the proposed structure, in which a backing plate is attached to a stepped joint A' (see Fig. 1) formed at the joint of unit panels 1, 1. This is related. The difference from the embodiment shown in FIG. 3 is that a bracket portion 1 is provided on the surface side of the flat plate 12'.
2'b is provided in a protruding manner, and a detent 13' is interposed between the flat plate 12' and the surface edge 3a of the unit panel 1.

Next, the effects of the proposed structure will be explained. The proposed structure simply uses inexpensive destances 13 and 13' with bolt insertion holes 13a and 13'a.
Standardized flat plate 12,1 used for outer wall 8
2' (see FIGS. 1 and 2) can be used. As a result, the proposed structure is composed of an inexpensive flat plate that does not require bending and an inexpensive distance, so the plate can be installed at low cost, and since a standardized flat plate is used, This has the practical effect that it is not necessary to prepare two types of backing plates in advance as in the conventional case, and management of the backing plates can be easily performed.
