したものがある。The conventional method of connecting the bottom plate and side wall of a prestressed I/concrete tank is to connect them with reinforcing bars or steel rods for prestressed concrete, and then integrate them by pouring concrete to create a completely rigid connection. In some cases, an elastic support material such as rubber is interposed between the two to form a joint.

There are some things that are kF, and in the case of a completely rigid connection, III! 1) The concentration of the vertical bending moment that occurs at the lower end of the side wall when the brace 1 is introduced due to the wall circumferential tension I, and in the case of this joint, the circumferential press 1 -res force as in 1. At the time of introduction, since horizontal displacement of the joint is impossible, it is necessary to deal with the concentration of vertical bending moment 1 that occurs at the abdomen of the side wall. After introducing the prestressing force using the directional tensioning material, it was customary to introduce a press 1 heresca using the circumferential self-tensioning material.

ス力を導入するものである。In addition, the bottom plate 1 is a joint surface between the bottom plate 1 and the side wall 2.
A support plate 6.6' made of steel etc. is provided on both the upper surface and the lower end surface of the side wall 2.
A solid, powder, or liquid anti-friction agent 7 is interposed between the support plates 6 and 6', and the side wall 2 is made movable on the bottom plate 1 surface, and the side wall 2 is moved in the circumferential direction of the side wall 2. A breath l-res force is introduced at , and then a prestress force is introduced in the vertical direction.

て、周方向プレストレス力の導入が可能となる。Due to the effect of the anti-friction agent 7 interposed between 6', the bottom plate 1 is restrained (horizontal movement is possible without bending), and the generation of vertical bending moment on the side wall 2 is suppressed to the maximum iJX limit. It becomes possible to introduce circumferential prestress force.

させることができる。After that, by introducing a prestress force into the vertical tension member 5, the joint between the bottom plate 1 and the side wall 2 is subjected to vertical prestress force against the bending moment of the applied load after the tank is completed. Therefore, the horizontal force can be effectively counteracted reliably by the horizontal resistance force obtained by multiplying the vertical prestress force by the friction coefficient of the anti-friction agent 7.

ことなく可能となるものである。In this case, by using a thin anti-friction agent 7 whose deformation due to the vertical load can be ignored and by increasing the vertical press 1~resistance amount, the bottom plate 1 and the side wall 2 can be joined to a completely rigid joint. Furthermore, since the welding can be achieved by reducing the amount of prestress in the vertical direction to a certain extent, a highly flexible welding state can be obtained after introducing the prestress force in the circumferential direction. Unlike rigid joints, rigid joints can be made without having to deal with vertical bending moments.

It has a trumpet-like or elliptical enlarged cross-sectional shape, and by using such a vertical sheath 3, when a prestress/stress force is introduced in the circumferential direction of the side wall 2, it will not be inserted inside. This allows horizontal movement of the vertical tension material 5, reduces the influence of bending on the tension material 5, and allows the horizontal movement of the side wall 2 to be more rapid and smooth.

。As described above, the method of joining the bottom plate and side wall of a tank made of prestressed concrete 1-1 according to the present invention is such that both the lower surface of the bottom plate and the lower end surface of the side wall, which form the joint surface between the bottom plate and the side wall, are made of steel or the like. The support plate is fixed, an anti-friction agent is interposed between the support plates, the side wall is made movable on the bottom plate surface, the presses 1 to 1 are introduced in the circumferential direction of the side wall, and then the anti-friction agent is interposed between the support plates. This method introduces a prestress force to the bottom plate and the side wall, without causing a concentration of vertical moment 1 at the lower end of the side wall or the abdomen when the prestress amount j is introduced in the circumferential direction as in the conventional case. This is an extremely useful invention in which any joining state from rigid joining to loose joining can be arbitrarily selected depending on the purpose of use of the constructed tank.
