Description

Technical Field

[0001] The present application relates to the technical field of building walls, and in particular to a radiation-proof wall and a construction method thereof. Background Art

[0002] For some places where ionizing radiation exists, such as nuclear power plants, laboratories and radiotherapy rooms in hospitals, in order to protect the human body from radiation hazards, radiation-proof walls are generally set up in the above-mentioned places to block or reduce the leakage of ionizing radiation.

[0003] However, the existing radiation protection wall forming method is mostly concrete pouring, which requires mixing materials on site and waiting for the concrete to solidify during construction. There is a general defect of low construction efficiency, which is difficult to meet the requirements of rapid construction and needs to be improved. Summary of the invention

[0004] In order to improve construction efficiency, the present application provides a radiation-proof wall and a construction method thereof.

[0005] In the first aspect, the present application provides a radiation-proof wall adopting the following technical solution: A radiation-proof wall comprises a plurality of wall units connected by splicing, a first splicing structure is provided between two adjacent wall units in the vertical direction, and a second splicing structure is provided between two adjacent wall units in the horizontal direction, the first splicing structure comprises a first splicing block vertically slidably arranged in the wall unit, and a first splicing groove provided at an end of the wall unit away from the first splicing block, the first splicing groove being used for vertically extending the first splicing block in the adjacent wall unit in the vertical direction; the second splicing structure comprises a second splicing block horizontally slidably arranged in the wall unit, and a second splicing groove provided at an end of the wall unit away from the second splicing block, the second splicing groove being used for horizontally extending the second splicing block in the adjacent wall unit in the horizontal direction, and a driving component for driving the first splicing block and the second splicing block to extend synchronously is provided in the wall unit.

[0006] By adopting the above technical solution, the radiation protection wall in the present application is composed of several wall units. During construction, the wall units can be prefabricated in the factory first, and then transported to the site for assembly. Compared with the traditional concrete pouring, the above construction method can effectively save the time of mixing materials on site and waiting for concrete to solidify, and the construction efficiency is high. When splicing two wall units, after the first splicing block of one wall unit is aligned with the first splicing groove of the other wall unit, or the second splicing block of one wall unit is aligned with the second splicing groove of the other wall unit, the operator only needs to control the first splicing block and the second splicing block to extend synchronously through the driving component, so that the first splicing block can be extended into the corresponding first splicing groove, or the second splicing block can be extended into the corresponding second splicing groove, which is easy to operate.

[0007] Optionally, the driving assembly includes a driving block slidably arranged in the wall unit and a driving stud rotatably connected to one side of the driving block, and a driving screw hole that cooperates with the thread of the driving stud is provided in the wall unit, and the movement direction of the driving block is perpendicular to the movement direction of the first splicing block and the second splicing block; a guide slope is provided at one end of the first splicing block and the second splicing block close to the driving block, and the guide slope is used to guide the first splicing block and the second splicing block to the outside of the wall unit when the driving stud rotates toward the side close to the driving block.

[0008] By adopting the above technical solution, when the driving stud is rotated toward the side close to the driving block, the guiding inclined surface will contact the driving block and synchronously guide the first splicing block and the second splicing block to the outside of the wall unit, so as to realize the rapid assembly of adjacent wall units. The above driving method only needs to rotate the driving stud once to control the synchronous movement of the first splicing block and the second splicing block, and the splicing efficiency is high.

[0009] In addition, the driving stud cooperates with the driving screw hole thread to play a certain self-locking role, making it difficult for the driving block to move in the wall unit, which is beneficial to improving the stability of the first splicing block and the second splicing block.

[0010] Optionally, the wall unit is provided with a first fixed groove that slides with the first splicing block, and a second fixed groove that slides with the second splicing block. A first tension spring is provided between the groove wall of the first fixed groove and the first splicing block, and a second tension spring is provided between the groove wall of the second fixed groove and the second splicing block. The first tension spring has a tendency to drive the first splicing block to be completely retracted into the first fixed groove, and the second tension spring has a tendency to drive the second splicing block to be completely retracted into the second fixed groove.

[0011] By adopting the above technical solution, before assembling the wall unit, the driving stud is first rotated to a position where the driving block is separated from the guiding inclined surface, and the first splicing block is received in the first fixing groove under the action of the first tension spring, and the second splicing block is received in the second fixing groove under the action of the second tension spring. Such a configuration can not only improve the stability of the first splicing block and the second splicing block during transportation and reduce the overall space occupied by the wall unit for easy stacking, storage and transportation; it also makes it unnecessary to place each wall unit in a specific direction when splicing, and the operation flexibility is high.

[0012] Optionally, the driving block includes an integrally formed first driving part and a second driving part, and the wall unit is provided with a first driving groove interconnected with the first fixed groove, and a second driving groove interconnected with the second fixed groove, the first driving part is slidably arranged in the first driving groove, the second driving part is slidably arranged in the second driving groove, the first tension spring and the first driving part are distributed in an alternating manner, and the second tension spring and the second driving part are distributed in an alternating manner.

[0013] By adopting the above technical solution, the first driving part and the second driving part are connected in an integrated manner, the integrity of the driving block is good, and the first splicing block and the second splicing block have high activity synchronization. The first driving groove and the second driving groove play a guiding and limiting role when the driving block moves, so that the first driving part and the second driving part can only move in a specified direction, which is conducive to ensuring the linkage effect of the first splicing block and the second splicing block with the driving block.

[0014] Optionally, a linkage gear is fixed to a side of the driving stud away from the driving block, and a linkage rack for meshing with the linkage gear is detachably provided in the wall unit, and the length of the linkage rack is not less than the spacing between adjacent linkage gears.

[0015] By adopting the above technical solution, when disassembling and assembling the wall unit, the linkage rack can be used to control the synchronous rotation of the linkage gears in two adjacent wall units, so as to simplify the two rotation operations into one, thereby further improving the disassembly and assembly efficiency of the wall unit.

[0016] Optionally, a mounting groove for accommodating a linkage rack is provided on the wall unit, the mounting groove is open on both sides in the horizontal direction, and a rubber pad for pressing against the linkage rack is fixed in the mounting groove, and the linkage rack can mesh with the linkage gear when extending into the mounting groove.

[0017] By adopting the above technical solution, when the linkage rack is not in use, it can be embedded in the installation groove for storage, so as to be quickly taken out when needed. In addition, when the linkage rack is stored in the installation groove, it can mesh with the linkage gear, which is conducive to further improving the stability of the linkage gear.

[0018] Optionally, the linkage rack includes a fixed part, a movable part located on one side of the fixed part, and a connecting part arranged on the side of the movable part facing the fixed part, and the movable part and the fixed part are both provided with continuous teeth for engaging the linkage gear, and the fixed part is provided with a connecting groove that slides with the connecting part, and the groove wall of the connecting groove is threadedly connected with a stopping bolt for tightening the connecting part.

[0019] By adopting the above technical solution, after loosening the stop bolt, the connecting part can slide in the connecting groove, so that the overall length of the linkage rack changes, thereby adapting to controlling the synchronous rotation of linkage gears with different spacings, and having strong practicality.

[0020] Optionally, an extension disk is provided on a side of the linkage gear away from the driving stud, and a hexagonal groove is provided on the extension disk.

[0021] By adopting the above technical solution, a screwdriver adapted to the hexagonal groove can be inserted into the groove, so that the extension disk can be controlled to rotate by the screwdriver, thereby driving the drive stud to move synchronously.

[0022] Optionally, a decorative panel is detachably provided on the wall unit, and the decorative panel is sleeved on the outer side of the extension plate and can cover the opening of the installation slot.

[0023] By adopting the above technical solution, the extension plate can cover the linkage gear and the linkage rack, which not only improves the aesthetics of the wall unit, but also prevents dust from accumulating at the meshing portion of the linkage gear and the linkage rack, so as not to affect the meshing transmission between the two.
