Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of concrete structure, and particularly relates to a medical radiation room wall concrete structure. BACKGROUND

[0002] Modern medicine uses radiation or radioactive drugs for medical examination and treatment. The radiation of rays and drugs is harmful to biology and environment, can induce gene mutation, and cause diseases. Therefore, in order to prevent the harm of rays to medical staff, surrounding residents and environment, a protection system must be set when a building with a radiation source is built.

[0003] At present, the construction of the anti-radiation building mainly increases the anti-radiation performance by selecting anti-radiation concrete or increasing the thickness of the structure. The super-thick anti-radiation structure has a heavy wall self-weight, a high bearing capacity of the foundation, a large construction difficulty, a high quality risk, and the construction joints between the concrete walls of the segmented construction can reduce the anti-radiation performance of the wall. The anti-radiation concrete is a special concrete with a large volume weight, a shielding capacity for gamma rays, X-rays or neutron radiation, and a poor penetration of the radioactive rays. Although the use of the anti-radiation concrete can reduce the structure thickness and the construction difficulty, the manufacturing cost is very high, the anti-radiation concrete is not easy to be configured on site, and strict maintenance and management are required in the use process. SUMMARY

[0004] The present application aims to provide a medical radiation room wall concrete structure to solve the problems in the prior art.

[0005] In order to achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows:

[0006] A medical radiation room wall concrete structure comprises a plurality of unit walls formed by segmental pouring from bottom to top, wherein each unit wall comprises: a hollow brick layer formed by splicing a plurality of anti-radiation special concrete hollow bricks and having interconnected inner cavities; a concrete layer poured in the inner cavities and outer sides of the hollow brick layer; a reinforcing rib layer arranged in the hollow brick layer and the concrete layer; and a plurality of lead plates embedded in the concrete layer and corresponding to the construction joints between the unit walls.

[0007] Preferably, the reinforcing rib layer comprises: a plurality of longitudinal steel bars penetrating through the hollow brick layer; a plurality of vertical steel bars arranged on both sides of the hollow brick layer and bound with the longitudinal steel bars; and a plurality of transverse steel bars arranged on both sides of the hollow brick layer and bound with the vertical steel bars.

[0008] Preferably, the upper end face of the hollow brick is concave from left to right, the lower end face is convex, the left side face is concave from top to bottom, and the right side face is convex, two adjacent hollow bricks are fixed together by the concave and convex matching of the left and right side faces, and two adjacent hollow bricks are fixed together by the concave and convex matching of the upper and lower end faces.

[0009] Preferably, a plurality of grooves are arranged on the front and rear side faces of the hollow brick.

[0010] Preferably, the concrete in the inner cavity of the hollow brick layer is thermal insulation concrete.

[0011] Preferably, the unit wall bodies are in contact with each other through the concave and convex surfaces arranged thereon, the upper end middle part of the unit wall body is concave downward to form a concave surface, and the bottom end middle part of the unit wall body is convex upward to form a convex surface.

[0012] Preferably, the thickness of the lead plate is 4-5mm, and the concrete layer is arranged in the lead plate and connected with the reinforcing rib layer.

[0013] Compared with the prior art, the advantages of the present application are that:

[0014] 1. The hollow brick made of the anti-radiation special concrete forms an anti-radiation special concrete hollow brick layer in the concrete layer, which eliminates the need for on-site pouring of a large amount of anti-radiation concrete, reduces the labor intensity and construction difficulty of workers, saves construction cost, effectively reduces the thickness of the wall structure, thereby reducing the self-weight load of the wall structure, ensuring the construction quality and construction safety, and setting the lead plate through the construction joint not only effectively increases the anti-radiation strength of the unit wall body construction joint and enhances the overall anti-radiation performance of the wall body, but also effectively improves the connection strength and waterproof performance between adjacent unit wall bodies, thereby improving the strength of the wall body and prolonging the service life of the wall body.

[0015] 2. The reinforcing rib layer arranged between the hollow brick layer and the concrete layer can effectively improve the tensile and bending strength of the house and enhance the integrity and stability of the wall body.

[0016] 3. The concave and convex mutual engagement connection mode between adjacent hollow bricks makes the joint gap between the hollow bricks into a fold line structure, thereby preventing the rays from directly penetrating through the joint gap between the hollow bricks, further improving the anti-radiation effect of the wall body, and the structure is simple and novel, and convenient for construction.

[0017] 4. This invention creates a zigzag structure at the construction joint between unit walls by setting concave and convex surfaces that make contact with each other. This blocks the path of radiation and effectively shields the radiation at the construction joint, thereby improving the radiation protection performance of the entire concrete wall. The structure is simple, reasonable, and highly practical. Attached Figure Description
