Description

Technical Field

[0001] This utility model relates to the field of composite wall technology, specifically an ionizing radiation shielding composite wall. Background Technology

[0002] A CT room is a room specifically used for installing and operating CT (Computed Tomography) equipment. CT rooms are an important part of a hospital's radiology or imaging department, used to perform CT scans to help doctors diagnose various diseases.

[0003] The walls of the current CT scanner room are composed of a galvanized steel sheet with powder coating, a keel layer, a shielding layer, and a decorative layer, from the outside in. The shielding layer is made of 4 mm thick lead sheets, which are fixed to the galvanized square tube keel on the surrounding walls and ceiling with stainless steel screws. Because lead sheets are relatively soft, they are prone to pitting and deformation due to impacts during later use. Utility Model Content

[0004] The purpose of this invention is to provide an ionizing radiation shielding composite wall to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ionizing radiation shielding composite wall, comprising a concrete wall, a supporting frame, and a stainless steel plate. The supporting frame is fixed to the surface of the concrete wall, and multiple lead plate mounting slots are distributed in the supporting frame. Lead plates are arranged in the lead plate mounting slots, and the shape of the lead plates is the same as that of the lead plate mounting slots. The stainless steel plate covers the supporting frame and is fixedly connected to the supporting frame by screws. The surface of the stainless steel plate is coated with an anti-radiation coating layer.

[0006] Preferably, the support frame consists of crossbeams and longitudinal beams. There are three crossbeams arranged longitudinally at equal intervals, and four longitudinal beams arranged laterally at equal intervals, intersecting the crossbeams. The lead plate mounting groove is formed by the longitudinal beams and crossbeams.

[0007] Preferably, the back of the support frame is fixed with multiple anchor rods.

[0008] Preferably, the stainless steel plate has through holes for screws to mate with, and the support frame has screw mounting holes on its front side.

[0009] Preferably, the anchor rod consists of a connecting rod with a threaded section and an anti-detachment cap fixed to the end of the connecting rod, and the back of the support frame has an anchor rod assembly hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are: this utility model forms a multi-layer protection by using concrete walls, lead plates, stainless steel plates and anti-radiation coatings sprayed on the surface of stainless steel plates, thereby improving the shielding effect of ionizing radiation.

[0011] The lead plate is installed in the lead plate mounting slot on the support frame. The support frame fixes the lead plate, which can avoid the problem that the lead plate material is soft and easily deformed. The multiple lead plate mounting slots distributed in the support frame facilitate the quick installation of the lead plate. The stainless steel plate covers the surface of the support frame, which can prevent the lead plate from being exposed.

[0012] Multiple anchor rods are fixed to the back of the support frame. The anchor rods can be embedded into the concrete wall during concrete pouring, thereby making the connection between the support frame and the concrete wall more secure.

[0013] The anchor rod and the support frame are connected by threads, which facilitates the installation of the anchor rod. Attached Figure Description
