Description

Technical Field

[0001] This invention belongs to the field of radiation protection technology, and more specifically, relates to a radiation protection ceiling plastering construction system and its application method. Background Technology

[0002] Special rooms in buildings such as nuclear reactors, research facilities, and hospitals generate large amounts of X-rays. Prolonged exposure to X-rays can lead to a buildup of radiation dose, damaging white blood cells and reducing their number. This weakens the immune system, making the body more susceptible to infection and disease, especially for infants and young children who are highly sensitive to X-rays. Therefore, radiation protection measures are necessary for these types of rooms.

[0003] To address the aforementioned issues, common radiation leakage prevention solutions during construction include ultra-thick concrete structures and lead plate protection. However, lead plates, as a heavy metal material, are costly, polluting, and harmful to human health. Furthermore, ultra-thick concrete structures are often limited by space constraints. Therefore, both are mostly used in low-level radiation protection construction. However, Chinese invention patent CN109694622A discloses a GR-type waterproof and radiation-proof coating, characterized by the following weight percentage components: 25-35% of the main material of the RG type; 15-25% flake graphite powder; 15-25% acetylene black; 15-25% carbonyl iron powder; 0.25% bactericide; 0.1-0.2% thickener; 0.2-0.4% defoamer; 0.1-0.3% dispersant; and the remainder is water. The main material of the RG type is selected from carboxylated styrene-butadiene latex, butadiene-styrene copolymer emulsion, styrene-acrylic polymer emulsion, or pure acrylic latex. The fillers are barium sulfate, calcium carbonate, and silica powder. Research has shown that barium sulfate, with its low cost, is a relatively good radiation protection material, and its long service life and other advantages have led to its widespread application in many fields.

[0004] Barium sulfate, as a radiation protection material, has many advantages over ultra-thick concrete structures and metal lead plate protection, and has demonstrated excellent performance in practice. However, the following technical problems still exist in the construction process: (1) The density of barium sulfate mortar is generally 2500 kg / m³-3400 kg / m³. As a radiation protection layer, its thickness is also larger than that of conventional plastering layers. Therefore, during the plastering process of the ceiling of the radiation protection space, the mortar is affected by the gravity of the mortar and the weak adhesion between the mortar and the ceiling surface of the building, resulting in a large amount of mortar falling off during the construction process, which leads to material waste; (2) The exothermic and shrinkage reaction of the mortar during the consolidation and drying process can also easily generate cracks in the plastering layer. In addition, the "hollowing" phenomenon caused by the vibration of the building ceiling during use will cause the plastering layer to fall off in pieces, which will bring safety hazards; (3) The construction joints and the gaps formed by the improper use of different materials and construction methods during construction can easily lead to radiation leakage. Summary of the Invention

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides a radiation-proof ceiling plastering construction system. By applying barium sulfate mortar to a wire mesh layer to form a radiation-proof plaster layer, it replaces lead plate radiation protection, effectively reducing costs and minimizing occupational health hazards and pollution. Furthermore, through the assistance of wire mesh and hooks, it achieves multi-layer plastering, layered staggered and interlayered wire mesh hanging structures, and layer-by-layer sealing, solving the problem of radiation leakage at vertical through-joints and shrinkage cracks in the plaster layer. The use of multi-layer wire mesh effectively eliminates the risk of thick layers of recrystallized barium sulfate plaster (2500 kg / m³-3400 kg / m³) falling off under its own weight. In addition, multi-layered staircase construction joints are reserved at the junction of the floor slab and wall before construction, eliminating radiation leakage at corners due to poor overlapping treatment. Simultaneously, the treatment at corners provides an anchoring support for the heavy ceiling, enhancing the overall stability of the wire mesh and plaster layer.

[0041] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects:

[0042] 1. This invention discloses a radiation-proof ceiling plastering construction system. By using barium sulfate mortar applied to a wire mesh layer to form a radiation-proof plaster layer, it replaces the lead plate radiation protection solution, effectively reducing costs and minimizing occupational health hazards and pollution. Furthermore, through the assistance of wire mesh and hooks, it achieves multi-layer plastering, layered staggered and interlayered wire mesh hanging structure, and layer-by-layer sealing treatment, solving the problem of radiation leakage at vertical through-joints and shrinkage cracks in the plaster layer. The use of multi-layer wire mesh effectively eliminates the risk of thick layers of recrystallized barium sulfate plaster with a density of 2500 kg / m³-3400 kg / m³ falling off under its own weight. In addition, multi-layer staircase construction joints are reserved at the junction of the floor slab and wall before construction, eliminating radiation leakage at corners due to poor overlap treatment. Simultaneously, corner treatment provides an anchoring support for the heavy ceiling, enhancing the overall stability of the wire mesh and plaster layer.

[0043] 2. The radiation-proof ceiling plastering construction system of the present invention uses a punching drive unit to convert driving force into mechanical movement of each module. The first moving punch assembly and the first mold base assembly, which are respectively moving and fixed parts, form a punching force to press the iron strip into shape. Combined with the first guide rod, the free end of the iron strip is controlled to move upward, thereby pressing out the bend at the end of the hook.

[0044] 3. The radiation-proof ceiling plastering construction system of the present invention realizes the transmission of two-way motion by utilizing a cam groove structure. The ingenious structural design simplifies the number of power sources and saves operating costs. In use, by controlling the rotation of the drive motor, the rotation of the first gear, the second gear, the torque amplifying drive wheel, the torque amplifying driven wheel, and the wheel groove turntable are realized in sequence. When the wheel groove turntable rotates, the push-pull slide rod and slide bar, which are slidably connected to the cam groove, can simultaneously realize left-right sliding and up-down sliding, thereby realizing continuous actions of punching and cutting.

[0045] 4. The radiation-proof ceiling plastering construction system of the present invention, through a two-stage gear and rack transmission module, simultaneously realizes the main body stamping and the right-angle stamping of the hook end. In use, by pressing the pressure block, the stamping handle drives the stamping head to move to the left, thereby stamping the iron strip into the stamping groove. At the same time, the rack part above the gear groove meshes with the fixed-axis driven gear, further transmitting power to the gear and rack module composed of the fixed-axis secondary gear and the rack, thereby converting the horizontal reciprocating motion into the vertical reciprocating motion. The opening angle is controlled by using the auxiliary pressure drive block and the lifting stop block to move the auxiliary pressure block, thereby folding the two ends of the iron strip pressed inside the stamping groove inward into a right-angle shape.

Detailed Implementation

[0057] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0058] According to a first aspect of the invention, such as Figures 1-10 As shown in the embodiment of the present invention, the radiation-proof ceiling plastering construction system includes:

[0059] The protective layer structure located on the inner side of the wall includes a radiation-proof plaster layer 210, a wire mesh 200 for providing adhesion to the radiation-proof plaster layer 210, and a hook connector for connecting the wire mesh; the radiation-proof plaster layer 210 is made of recrystallized barium sulfate mortar with a density of 2500 kg / m³-3400 kg / m³.

[0060] A hook processing unit for processing hook connectors, comprising a mold base assembly and a moving punch assembly; used to assist in the production of the required hook connectors;

[0061] By placing the iron bar 4 between the mold base assembly and the moving punch assembly, the iron bar 4 is pressed into a hook connector by impact force, and the wire mesh 200 is hoisted to the inside of the wall using the hook connector to reduce the shedding of the radiation-proof plaster layer 210; the hook connector is installed in a staggered manner between layers to reduce the amount of radiation leakage at the hook connector.

[0062] like Figure 3 As shown, in this embodiment of the invention, the radiation-shielding plaster layer 210 includes:

[0063] The wall plaster layer is formed by applying recrystallized barium sulfate mortar to a 200-mesh wire mesh and is in direct contact with the inner side of the wall.

[0064] The interconnected plaster layer is formed by applying recrystallized barium sulfate mortar to a steel wire mesh 200 and placing it on the inner side of the interconnected wall plaster layer.

[0065] like Figure 3 As shown, in this embodiment of the invention, the radiation-shielding plaster layer 210 includes:

[0066] The wall plastering layer consists of a primary plastering layer 211;

[0070] Steel mesh hook 222 is used to connect the internal steel wire mesh between the radiation-proof plaster layers 210;

[0071] The wall-mounted hook 221 and the steel mesh hook 222 are made of lead.

[0072] In this embodiment of the invention, a radiation-shielding plaster layer is formed by applying barium sulfate mortar to a wire mesh layer to replace the lead plate radiation protection solution, effectively reducing construction costs and minimizing occupational health hazards and pollution. Furthermore, the construction method, assisted by the wire mesh and hooks, achieves multi-layer plastering, layered staggered and interlayered wire mesh hanging structure, and layer-by-layer sealing, solving the problem of radiation leakage at vertical through-joints and shrinkage cracks in the plaster layer. The use of multi-layer wire mesh effectively eliminates the risk of thick layers of recrystallized barium sulfate plaster with a density of 2500 kg / m³-3400 kg / m³ falling off under its own weight. In addition, pre-reserving multi-layer staircase construction joints at the junction of the floor slab and wall eliminates radiation leakage at corners due to poor overlapping treatment. Simultaneously, corner treatment provides an anchoring support for the heavy ceiling, enhancing the overall stability of the wire mesh and plaster layer.

[0073] During construction, a sufficient number of wall-connecting hooks and steel mesh hooks are pre-fabricated using a hook processing unit for connecting the wire mesh during construction. Next, on the construction site, the wall-connecting hooks are positioned on the inner side of the wall using screws, with the hook connectors arranged in an array spaced 50-70cm apart. The wire mesh is then attached to the wall-connecting hooks, ensuring effective connection at each point. Finally, the steel mesh hooks are attached to the wire mesh, ensuring proper connection between the steel mesh hooks and the wall-connecting hooks. The wire mesh is staggered to prevent radiation leakage. Next, recrystallized barium sulfate mortar with a density of 2500 kg / m³-3400 kg / m³ is applied to the wire mesh 200 and allowed to set. Then, a second layer of wire mesh is attached to the lower end of the wire mesh hook, and the secondary wire mesh hook is attached to the wire mesh, ensuring that the wire mesh hook and the wall-connecting hook are staggered. Repeating the above steps completes the construction of a highly stable multi-level barium sulfate mortar radiation shielding layer.

[0091] In this embodiment of the invention, a two-stage gear and rack transmission module is used to achieve the stamping of the main body and the right-angle stamping of the hook end. In use, by pressing the pressure block 365, the stamping handle 3622 drives the stamping head 3621 to move to the left, thereby stamping the iron strip 4 into the stamping groove 3611. At the same time, the rack part above the gear groove 3631 meshes with the fixed-axis driven gear 3632 to transmit power, further transmitting power to the gear and rack module composed of the fixed-axis secondary gear 3633 and the rack 3634, thereby converting the horizontal reciprocating motion into the vertical reciprocating motion. The auxiliary pressure drive block 3635 and the lifting stop block 3637 are used to move the auxiliary pressure block 3638 to control the opening angle, thereby folding the two ends of the iron strip 4 pressed inside the stamping groove 3611 inward into a right-angle shape.
