[0055] In order to solve the problem that the prior art cannot effectively reinforce the construction joint position or the position prone to cracking, thereby causing the anti-radiation material to be easily damaged and unable to play the effect of preventing radiation. Figures 1-9 As shown in the figure, a hospital anti-radiation post-pouring strip includes a binding steel bar, two plugging structures 1 arranged on the binding steel bar, and a post-pouring strip concrete arranged between the two plugging structures 1. The plugging structure 1 includes a plugging support seat 2 matched with the binding steel bar, and a reinforcing structure 3 arranged on the plugging support seat 2 and integrally connected with the bottom plate concrete and the post-pouring strip concrete.

[0056] In practice, first, the bottom plate steel bar is bound, and then the plugging structure 1 composed of the plugging support seat 2 and the reinforcing structure 3 is arranged on the bottom plate steel bar at the positions on both sides of the post-pouring strip area. After installation, the upper layer steel bar is bound (the upper layer steel bar binding can directly limit the plugging structure 1, or other support structures can be used for anti-expansion form support). After the upper layer steel bar binding is completed, the protective formwork is covered on the reinforcing structure 3, and then the bottom plate concrete is poured. After the bottom plate concrete is poured and meets the requirements, the bottom plate concrete on the plugging structure 1 is completely chipped and cleaned to form a chipped connection edge. After cleaning, the post-pouring strip concrete is poured and maintained. In this embodiment, the plugging support seat and the reinforcing structure are matched to form an integral body with the bottom plate concrete and the post-pouring strip concrete, which can effectively reinforce the construction joint position or the position prone to cracking, thereby avoiding concrete cracking and unable to play the effect of preventing radiation.

The reinforcing member is composed of the reinforcing plate and the reinforcing rib, which not only realizes the reinforcement of the connection between the upper and lower positions of the bottom plate concrete and the post-pouring strip concrete, but also has the radiation-proof layer coated on both surfaces of the reinforcing plate, thereby further reinforcing the radiation-proof effect of the upper and lower rooms of the hospital at the position of the post-pouring strip on the basis of the combination of the concrete and the reinforcing plate, and also achieving the water-stopping effect. Even if the reinforcing plate cracks, it can be effectively protected by the reinforcing plate and the radiation-proof layer. Other structures are not excluded for the reinforcing member.

The lower grid plate and the upper grid plate are limited to the double-layer structure with openings at the top and forming grooves, which aims to facilitate the arrangement of the L-shaped plate in the groove, one is to effectively block the bottom plate concrete to avoid its entering between the two blocking structures, and the other is to facilitate the quick cleaning of the chiseled bottom plate concrete, thereby improving the construction efficiency and facilitating the secondary use of the L-shaped plate, thereby avoiding the waste of materials.

[0063] Embodiment 5

[0064] On the basis of Embodiment 4, each layer of the lower grid plate 4 and the upper grid plate 5 respectively comprises an angle steel 14, a steel bar net 15 arranged on the angle steel 14, and a reinforcing steel bar 16 for reinforcing the steel bar net 15.

In the case that the bottom edge of the angle steel is free of the concrete accumulation area on one side of the groove, the bottom surface of the double-layer structure can be open or not. Otherwise, the opening is required. In this embodiment, each layer of the lower grid plate and the upper grid plate respectively comprises an angle steel, a steel bar net, and a steel bar, which aims to ensure the strength and improve the tensile capacity.

[0065] Embodiment 6

The arrangement of the fixing structure is convenient for preventing the elastic reset structure from being difficult to contract, the channel from being difficult to be clamped on the binding hole steel bar, and the problem of low installation efficiency.

When the first T-shaped limiting plate 24 is fixed and retracted into the first T-shaped groove 22, the first T-shaped groove 22 compresses the second spring 27 to retract, so that the second T-shaped limiting plate 28 is arranged in the second T-shaped groove 26, and vice versa. The second spring 27 is reset, and the second T-shaped limiting plate 28 is matched with the steel bars.
