Abstract

A reinforced concrete panel for a nuclear island plant comprises a concrete body made of concrete, wherein the concrete body is provided with two first reinforcement groups parallel to each other; the first reinforcement group comprises a plurality of first reinforcing bars arranged in parallel; two second reinforcement groups are arranged between the two first reinforcement groups; the second reinforcement group comprises a plurality of second reinforcing bars arranged in parallel; the second reinforcing bars in the two second reinforcement groups are respectively fixed to the first reinforcing bars in the first reinforcement groups; the angle formed by the first reinforcing bar and the second reinforcing bar is an acute angle or a right angle; and the second reinforcing bars are stainless steel bar. The reinforced concrete panel of the invention has good corrosion resistance, impact resistance, anti-magnetic penetrating property and good adaptability to high temperature and low temperature environments.

Example Embodiment

[0015] Hereinafter, the present invention will be further described in detail through specific embodiments in conjunction with the drawings.
[0016] A reinforced concrete slab for nuclear island plant, which can be used as the bottom plate of nuclear island plant, reactor plant barrel, internal structure of reactor plant, and shear walls and floor slabs in other plant buildings. Such as figure 1 with figure 2 As shown, it includes a concrete body 1 made of concrete, and the concrete body 1 has a square or circular plate structure. Two first rebar groups 3 parallel to each other are arranged in the concrete body 1. Specifically, when the concrete body 1 is manufactured, the first rebar groups 3 are embedded in the concrete body 1. A number of first steel bars arranged in parallel are provided in the same first steel bar group 3, and the first steel bars in the two first steel bar groups 3 extend parallel in the same direction.
[0017] There are also two second steel bar groups 2 between the two first steel bar groups 3. Each second steel bar group 3 is provided with a number of second steel bars arranged in parallel, and the second steel bars in the two second steel bar groups 2 All extend in parallel in the same direction. The second steel bars in the two second steel bar groups 2 are respectively fixed to the first steel bars in the two first steel bar groups 3, and the fixing method can be lashing or welding. In order to ensure the fixing effect, welding is preferred. When the first steel bar and the second steel bar are fixed to each other, the angle formed by the two is an acute or right angle, and they are not placed in parallel, thereby increasing the contact area with the concrete and strengthening the fixation with the concrete. Wherein, the second steel bars are stainless steel bars, and the first steel bars can be ordinary steel bars or stainless steel bars.
[0018] Wherein, the stainless steel bars are made of any one or more of austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, and austenitic-ferritic stainless steel. Improve the durability, impact resistance and explosion resistance of concrete slabs.
[0019] In a preferred solution, the angle formed by the first steel bar and the second steel bar is a right angle. Thereby it has the largest contact area with concrete, so that the structure of the concrete slab is further strengthened. The two first steel bar groups 2 are fixed by binding or welding, which can enhance the overall structural strength of the first steel bar and the second steel bar.
[0020] image 3 Is the tensile test chart of ordinary concrete slab, Figure 4 This is the tensile test diagram of the reinforced concrete slab used in the nuclear island plant of the present invention. Through comparison, it can be known that under the same pressure, the reinforced concrete slab of the present invention has a smaller stretch than ordinary concrete slabs. It can be seen that its impact resistance and structural strength are better.
[0021] The above content is a further detailed description of the present invention in conjunction with specific embodiments, and it cannot be considered that the specific implementation of the present invention is limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, a number of simple deductions or substitutions can also be made without departing from the concept of the present invention.
