Embodiment

[0018] The new ray device protection engineering project in a Shanghai International Hospital, according to the characteristics of the ray device, requiring the structure of the grinding room as a machine room to ensure the quality of protective engineering. However, there are two stretchable seams in the provided rough room, and there is a telescopic seam 1 on the ceiling 3 and the wall 2, and the width of the telescopic seam 1 is 10 cm. The applicant has studied the calculation by co-study with the Dibex Design Institute, and the maximum variable of the expansion is 3 cm. After multiple tests, the inventors are used to be folded into a ω type, placed in the telescopic seam 1; the lead plate 4 is disposed on the outer side of the shed 3 or the inside of the wall 2, and is disposed in the inside of the wall 2 On both sides of the slit 1; the central projection of the lead plate 4 is disposed in the center of the telescopic seam 1. The lead plate 4 is fixed to both sides of the tel...

Abstract

The invention relates to a filling device for an expansion joint of a ray protection engineering building structure, and belongs to the technical field of radiation protection. The filling device is filled in an expansion joint of a building construction surface, and a lead plate with an elastic structure is arranged in the expansion joint; and the cross section of the lead plate in the width direction is omega-shaped. According to the filling device, by arranging the filling lead plate with the elastic structure, expansion joints existing in a blank room are filled, and the technical problem of radiation leakage in the using process of a machine room is solved. According to the technical scheme, the manufacturing cost is low, and the effect of preventing the radiation leakage is safe and reliable.

Description

Technical field [0001] The present invention relates to a filling device for a radiation protection engineering structure (a radiation protection technology). Background technique [0002] With the improvement of medical skills, the development of medical equipment has changed, in the construction of modern hospitals, more and more ray device equipment is widely used in medical technology, radiopaterials, etc., and ray devices. Application, giving people a huge benefit, and also bringing harm to people, equipment rooms equipped with ray devices require a facility with strict protection against rays, avoiding medical staff and patients from radiation damage. According to the characteristics of the ray device, the structure of the rough room that is usually required as the machine room is stable and complete to ensure the quality of the protection project. However, due to the requirements of the construction process or the quality of construction, the ceiling of the rough room of t...
