TECHNICAL FIELD
[0001] The utility model relates to medical perspective inspection instrument technical field, concretely relates to a protective board room frame suspended ceiling. BACKGROUND
[0002] Medical radiation equipment (such as X-ray machine, CT scanner, radiotherapy equipment, etc.) is a kind of equipment for medical diagnosis and treatment, which generates the image of human body internal structure or is directly used for treating diseases by generating and using ionizing radiation (such as X-ray, gamma ray, etc.). In order to protect medical staff and patients from the influence of radiation generated by medical radiation equipment, it is usually necessary to install medical radiation equipment in protective board room for use.
[0003] At present, the existing protective board room for medical radiation equipment is made by splicing and installing protective boards on the board room frame, and these protective boards are mostly made of lead plate, tungsten alloy plate and other radiation-proof plate materials, so they are relatively heavy. The existing protective room only relies on the board room frame as structural support, causing the top frame of the board room frame to bear a relatively heavy weight. Although the top frame can disperse part of the load to the side frame of the board room frame, the middle part of the top frame lacks necessary support, so the frame strip of the top frame is prone to disengagement at the connection, which has high security risks. SUMMARY
[0004] Therefore, the utility model aims at providing a protective board room frame suspended ceiling, which can connect the roof surface through multiple hangers to form multiple support points of the top frame, thereby improving the carrying capacity of the top frame.
[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme:
[0006] A protective board room frame suspended ceiling comprises multiple frame strips connected to each other and multiple hangers arranged on the frame strips respectively; the hanger comprises a connecting strip, a suspender, a first nut and a second nut; one end of the connecting strip is connected to the frame strip; the suspender is vertically arranged, the upper end of the suspender is used for connecting the roof surface, and the lower end of the suspender penetrates the other end of the connecting strip; the first nut and the second nut are both threadedly connected to the lower end of the suspender and are respectively located on the two sides of the connecting strip; the first nut and the second nut are reversely rotated to clamp the connecting strip.
[0007] As an optional scheme, the connecting strip is U-shaped, and the open end of the connecting strip is fixedly sleeved on the frame strip; the lower end of the suspender penetrates the closed end of the connecting strip; the first nut and the second nut are respectively located on the inner and outer sides of the connecting strip.
[0008] As an optional solution, washers fitted onto the rod are provided between the first nut and the connecting bar, and between the second nut and the connecting bar.
[0009] As an optional solution, a protective plate is provided at the connection point of the four frame strips. The protective plate is cross-shaped and its four ends are respectively connected to the four frame strips.
[0010] As an optional solution, the lower edges of the four ends of the protective plate are respectively provided with chamfers, and the connection surface between the protective plate and the frame strip is the bevel of the chamfer.
[0011] As an optional solution, a corner bracket is provided at the angle between two adjacent frame strips. The corner bracket is triangular, with its two sides connected to the two frame strips respectively.
[0012] As an optional solution, the straight edge of the corner bracket is folded upward and connected to the frame strip by screws.
[0013] By adopting the above technical solution, this utility model will have the following beneficial effects:
[0014] This utility model provides a protective prefabricated house frame ceiling. By rotating the first nut and the second nut in opposite directions, the first nut and the second nut can be moved towards each other until they clamp and fix the connecting strip at the lower end of the hanger. In this way, the upper end of the hanger is connected to the roof surface, which can restrict the vertical movement of the frame strips of the prefabricated house frame and form the support point of the top frame. Multiple hangers set on the frame strips can form multiple support points of the top frame, thereby improving the load-bearing capacity of the top frame, reducing stress concentration, and preventing the frame strips of the top frame from detaching and being damaged at the connection.
