Abstract

PURPOSE:To prevent occurrence of cracks at the bottom corner part of a low temperature-liquid storing tank, by constructing the part connecting the side wall to the bottom floor part of the tank with a steel-fiber reinforced concrete. CONSTITUTION:A steel-fiber reinforced concrete 2, obtained by mixing steel fibers with aggregate, is used in place of ordinary concrete at the bottom corner part 1 of a concrete tank where the possibility of causing rupture is highest, so as to increase the strength at the part 1 of the tank. Here, since the steel- fiber reinforced concrete is superior in its tensile, bending and shearing strengths as compared with the ordinary concrete and moreover has a very high toughness because of its particular rupture characteristics, it is enabled to prevent occurrence of cracks at the bottom corner part of a low temperature-liquid storing tank.

ことが好ましい。In general structures, it is common to deal with areas where large moments are generated by increasing the size of the parts. However, in some corners of the tank, it is necessary to If you try to solve this problem by increasing the thickness, it will become structurally stiff (second, the moment will increase. In other words, if you make the member thicker, the moment will also increase, so it will be less effective. Therefore, for part of the tank U) corner, it is preferable to use a material with high strength by keeping the thickness of the member unchanged or by making it thinner.

-The formwork used when constructing the tank is also lll1l! This was done in an attempt to eliminate the corbels so that the X formwork could be shared, or to keep the corbels to a minimum (2). It is characterized by being constructed using steel fiber concrete mixed with steel fibers.

In order to increase the strength of a corner part, even if it is desired to insert more reinforcing bars in this part, there is a limit to the amount that can be inserted, and it is difficult to insert enough reinforcing bars. Also, a large haunch must be provided at some of the corners (second) for strength reasons.

。The present invention uses steel fiber concrete (2), which is a tough and tenacious material with improved tensile, bending, and shear strength compared to ordinary concrete, and has significantly different fracture properties from ordinary concrete. , the corner bottom (which is the joining part between the side wall (31) and the bottom floor (4)
1), it is difficult to crack even if a large moment occurs in the corner bottom (1), and the thickness can be made thinner to make the corner bottom (11) stiffer. , the amount of reinforcing bars can be reduced and the reinforcement arrangement can be made smoother (2).Steel fiber concrete I+
- Since F21 has a high thermal conductivity, it can alleviate the sudden temperature difference between the bottom floor (4) and the first wall (31), thereby reducing temperature stress. In addition, during tank construction (2), it is also possible to prevent cracks during concrete hardening, which are particularly likely to occur at the corner bottom (2) due to the heat C2 emitted when concrete hardens.

得る。As described above, according to tank C2 of the present invention, since the corner bottom of the tank is constructed using steel fiber concrete, the strength of the easily broken corner bottom of the tank is increased,
Since the strength can be increased, the amount of reinforcing bars can be reduced, and the thickness can be made thinner, the side walls and bottom floor of the tank can be designed with the same thickness or with a slight haunch, making it possible to change the placement and shape of the reinforcing bars. The structure of the frame can also be simplified, and excellent effects such as formwork work and tank construction can be performed economically.
