Novel rectangular reinforced concrete pool wall corner reinforcing steel bar configuration mode
Technical Field
The invention belongs to the technical field of reinforced concrete structure optimization, and particularly relates to a novel rectangular reinforced concrete pool wall corner reinforcing steel bar configuration mode.
Background
In the process of constructing the pool, the outer side of the pool wall of the pool is under the action of soil pressure, water pressure and ground overload pressure, so that the bending moment of the corners and the root parts of the pool wall of the pool is large, and in order to meet the requirements of strength and crack control, reinforcing steel bars are required to be arranged on the outer side of the corners of the pool wall of the pool, namely, corner reinforcing steel bars are arranged. The load is dispersed and transferred through the configuration of the corner reinforcing steel bars, the wall body is prevented from cracking, the damage of a building caused by stress concentration is avoided, and the stability of the pool structure is guaranteed.
When the corner reinforcing steel bars are configured, the concrete water tank structure is required to be configured according to CECS 138: 2002, 7.1.11: the steel bars at the corners of the pool wall of the cast-in-place reinforced concrete pool should be anchored into the adjacent pool wall or roof with enough length, the anchoring length should be calculated from the inner side of the pool wall, and the minimum anchoring length should be adopted according to the regulations of the concrete structure design Specification GB 50010. At present, designers are all according to the requirements of the specification when carrying out reinforcement design at the corner of the pool wall.
When the existing pool wall of the pool is designed with reinforcing bars, a configuration mode that the outer side of the corner of the pool wall is provided with horizontal reinforcing bars is adopted. Referring to fig. 1, fig. 1 shows the reinforcement at the corner of the conventional pool wall, in which d shows the horizontal reinforcement at the outer side of the pool, and e shows the reinforcement at the corner of the pool arranged in a staggered manner, it can be seen that the reinforcement at the corner of the conventional pool wall is formed by designing the horizontal through-length reinforcements of the pool walls at two adjacent sides at the similar horizontal plane, the distance between the horizontal through-length reinforcements is 200mm, the lengths of the horizontal through-length reinforcements anchored into the adjacent pool walls are 1m (i.e. 35d), and binding and connecting the horizontal through-length reinforcements, and the corners are fully encrypted. Referring to fig. 2 in combination, fig. 2 is an expanded elevation view of reinforcement at corners of a conventional pool wall, in which a shows a non-reinforced region of a horizontal reinforcement at the middle of the pool wall, b shows a horizontally reinforced region at the corners of the pool wall, and c shows a lapped region of a horizontal through-length reinforcement at 35d of the pool wall. The existing corner steel bar configuration mode has the disadvantages of inconvenient operation of reinforcement binding construction of workers, long construction period, high labor cost for binding, large steel bar consumption and high water tank manufacturing cost.
