The protection wall 100 includes a first protection wall body 110 and a second protection wall body 120, a fold-line-shaped flexible isolation slit 200 is reserved between the first protection wall body 110 and the second protection wall body 120, the first protection wall body 110 is L-shaped, and the first protection wall body 110 is integrally cast with a vertical member 10 and a horizontal member 20 of a main body structure connected with the first protection wall body 110.
According to the utility model, the fold-line-shaped flexible isolation joint 200 is arranged between the first protection wall body 110 and the second protection wall body 120, so that the connection rigidity between the concrete wall body and the main body structure is reduced, and the stress is released and the induced crack is developed in the range of the flexible isolation joint. Meanwhile, the broken-line-shaped flexible isolation joint 200 makes full use of the principles of blocking and misconnection in radiation protection, and effectively prevents rays propagating along a straight line from penetrating out of the isolation joint.
In some embodiments of the radiation-proof flexible connection structure for concrete walls of the present utility model, the first protection wall body 110 is located at the left and right sides and the top of the second protection wall body 120, that is, the second protection wall body 120 is located between the horizontal member 20 of the main structure and the first protection wall body 110, the bottom end of the second protection wall body 120 is fixedly connected with the horizontal member 20 of the main structure, and a fold-line-shaped flexible isolation slit 200 is left between the two sides and the top end of the second protection wall body 120 and the first protection wall body 110. The folded-line flexible separator slit 200 is effective to reduce stiffness transfer between the second protective wall 120 and the main structure.
In some embodiments of the radiation-proof flexible connection structure of a concrete wall, the first protection wall 110 is symmetrically arranged on the left and right sides of the second protection wall 120, so as to ensure that the walls are uniformly stressed.
As shown in fig. 1 and 3, the first protection wall 110 and the second protection wall 120 are provided with protection wall steel bars 400 that meet the design and construction requirements. The lower end of the protective steel bar 400 is anchored into the lower beam (plate) connected with the protective steel bar, the upper end and the two sides respectively penetrate through the fold-line-shaped flexible isolation joints 200 and are anchored into the frame column and the upper beam (plate), so that the out-of-plane rigidity of the concrete radiation-proof wall body is enhanced, and the out-of-plane displacement is effectively limited.

The protective lead plate 300 can effectively strengthen the ray blocking capability of the fold-line-shaped flexible isolation joint 200.
As shown in fig. 1 and 2, the fold-shaped flexible separator slit 200 includes a first vertical section 210, a horizontal section 220, and a second vertical section 230, the first vertical section 210 and the second vertical section 230 being vertically left at different sides of both ends of the horizontal section 220, the first vertical section 210, the horizontal section 220, and the second vertical section 230 being integrally formed in a stepped crease shape. The slit width of the fold-line-shaped flexible isolation slit 200 should meet the structural deformation requirement specified in the specification, so that after the main body structure is deformed, the second protection wall 120 is not pulled and pressed, and the rigidity transmission is reduced. Preferably, the width of the fold-line-shaped flexible isolation joint is 20-50 mm, and the structural deformation requirement specified by the specification is met, so that the second protective wall 120 is not pulled and pressed after the main body structure is deformed.

In some embodiments of the present utility model, the horizontal section 220 of the fold-line-shaped flexible separator slit 200 is internally provided with a flexible separator plate, and the first vertical section 210 and the second vertical section 230 are filled with polyurethane foam filling material and sealed with silicone adhesive equivalent sealing ointment. Considering that the flexible partition plate at the horizontal section 220 is easy to generate dislocation movement phenomenon when the concrete of the main structure and the second protection wall 220 is poured once, the second protection wall 220 is poured again after the concrete of the main structure reaches the design strength. Before the second protective wall 220 is cast, the fixed end construction joint 500 should be roughened, cleaned and laid with a cement slurry. Preferably, the gap between the first vertical section 210 and the second vertical section 230 of the fold-line-shaped flexible insulation slit 200 is filled 15 days after the second protective wall 120 is secondarily poured.
In some embodiments of the present utility model, the ratio of the long side to the short side of the inner side and the short side of the first protection wall 110 is taken as 2, wherein the long side length may be generally taken as 200-250 mm. As shown in fig. 1 and 3, the length of the long side of the first protection wall 110 is H, and the length of the short side is H/2. Meanwhile, it should be noted that the length of the L-shaped first protection wall 110 integrally cast with the main structure should not be too long, so as to avoid generating larger lateral stiffness, and increase the earthquake effect, resulting in structural cracking.
Of course, the present utility model is capable of other various embodiments and its several details are capable of modification and variation in light of the present utility model, as will be apparent to those skilled in the art, without departing from the spirit and scope of the utility model as defined in the appended claims.
