Description

Technical Field

[0001] This utility model relates to the field of building decoration engineering technology, and in particular to a radiation-proof ceiling installation node unit. Background Technology

[0002] Currently, ceiling installation technology in building decoration projects is relatively mature, with ordinary ceilings primarily focusing on aesthetics, lightweight design, and ease of construction. However, in special locations with radiation protection requirements, such as medical, scientific research, and nuclear industry fields, traditional ceilings cannot meet radiation protection requirements. Existing technologies typically use lead plates or concrete structures for radiation-proof ceilings, but these solutions suffer from problems such as heavy weight, complex construction, and high costs. In recent years, with the increasing demand for radiation protection, lightweight and modular radiation-proof ceiling technology has gradually become a research hotspot, but existing technologies still struggle to balance protective performance with ease of construction.

[0003] A search revealed Chinese patent publication number CN218149206U, which discloses a ceiling panel installation node. The node includes a wall, an installation plate, and a ceiling panel. The installation plate is fixedly connected to the wall using expansion bolts. A connecting column is fixedly connected to the bottom of the installation plate, and a support plate is fixedly connected to the bottom of the connecting column. The connecting column has a T-shaped groove inside, and two symmetrically arranged sliding grooves communicating with the T-shaped groove are formed on the side wall of the connecting column. A rotating block is located inside the T-shaped groove, and a threaded rod is fixedly connected to the bottom of the rotating block. A connecting block is threadedly connected to the threaded rod. Two symmetrically arranged pressure plates are fixedly connected to the outer wall of the connecting block. The two pressure plates are slidably connected inside the two sliding grooves. When the ceiling panel needs to be removed, simply rotate the threaded rod to loosen the pressure plates, allowing for easy removal of the ceiling panel. The operation is simple and facilitates wider adoption.

[0004] When installing the device on the mounting plate, the expansion bolts need to penetrate the mounting plate, which damages the mounting plate. When the device is used in scenarios requiring radiation protection, such as hospital radiology departments, the damage to the mounting plate will affect the radiation absorption effect of the radiation-proof coating on the surface of the mounting plate, affecting the subsequent use of the mounting plate and reducing the safety during use. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a radiation-proof ceiling installation node unit, which aims to improve the problem of radiation leakage from the contact between the expansion bolts and the structure when installing lead plate layers in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a radiation-proof ceiling installation node unit, comprising a concrete structural slab, wherein the installation node unit further comprises a first lead plate layer, angle iron, and a second lead plate layer;

[0007] Two first lead plate layers are stacked and laid flat on the bottom surface of the concrete structure slab. The angle iron is fixedly installed on the bottom surface of the first lead plate layer by expansion bolts. The second lead plate layer is fixedly installed on the inside of the angle iron by expansion bolts. A thick steel plate pressure strip is provided at the connection between the expansion bolt and the second lead plate layer. The extended end of the expansion bolt and the thick steel plate pressure strip are located on the inside of the second lead plate layer.

[0008] Two fixed seats are fixedly connected to one side of the angle iron. A connecting rod is rotatably installed on the inner side of the two fixed seats. A rotating assembly is provided between the two connecting rods. The bottom surface of the first lead plate layer abuts against two abutment plates.

[0009] Through the above technical solution: the abutment plate abuts against the bottom surface of the first lead plate layer, thus supporting the first lead plate layer and preventing the first lead plate layer from bending due to excessive spacing between support points, which would reduce its radiation resistance performance. The angle iron, the first lead plate layer and the second lead plate layer can be fixed to the bottom of the concrete structure slab by expansion bolts.

[0010] As a further description of the above technical solution:

[0011] The second lead plate layer is bent, and one side of the second lead plate layer is in contact with the first lead plate layer, and the first lead plate layer and the second lead plate layer are fixedly bonded together.

[0012] The above technical solution involves a bent second lead plate layer, which protects the connection between the expansion bolts and the structure, preventing radiation from leaking out through the connection and enhancing radiation protection performance.

[0013] As a further description of the above technical solution:

[0014] One end of the expansion bolt passes through the two first lead plate layers and extends into the interior of the concrete structural slab, and the surface of the expansion bolt is coated with an anti-corrosion coating.

[0015] The above technical solution allows the top of the expansion bolt to extend into the top of the concrete structural slab, thus increasing the stability of the expansion bolt installation on the angle iron. Furthermore, the surface of the expansion bolt is electroplated with an anti-corrosion coating, which prevents the expansion bolt from rusting due to prolonged use.

[0016] As a further description of the above technical solution:

[0017] The rotating assembly includes a worm gear and a worm. The worm gear is fixedly installed between two connecting rods, and the worm is located at the bottom of the worm gear. The worm gear and the worm are connected by meshing.

[0018] With the above technical solution: the worm is set at the bottom of the worm wheel, and the worm wheel is meshed with the worm. Therefore, the worm can be rotated to drive the worm wheel to rotate. When the worm wheel rotates, it can stably drive the connecting rod to rotate inside the fixed seat.

[0019] As a further description of the above technical solution:

[0020] A connecting seat is provided on one side of the angle iron. A screwing block is provided on the outer surface of the connecting seat, and one end of the screwing block is connected to the worm gear. The worm wheel and the worm gear are located inside the connecting seat.

[0021] The above technical solution involves a worm gear that is rotatably mounted on the inner wall of the connecting seat via a rotating shaft, thus ensuring stable rotation of the worm gear inside the connecting seat. A turning block is located on the outer side of the connecting seat, allowing the user to easily rotate the worm.

[0022] As a further description of the above technical solution:

[0023] The inner sides of the two fixed seats are provided with connecting rods, and one end of the connecting rod is fixedly installed on the surface of the connecting rod.

[0024] The above technical solution allows the worm gear to drive the connecting rod to rotate, which in turn causes the connecting rod to deflect. As the connecting rod deflects, its height also changes. Furthermore, the self-locking property of the worm wheel and worm gear prevents the connecting rod from falling downwards once it has deflected to the designated position.

[0025] As a further description of the above technical solution:

[0026] A rotating shaft is rotatably mounted at the end of the connecting rod, and adjusting rods are fixedly connected to both ends of the rotating shaft, with a stop plate fixedly mounted on the top surface of the adjusting rods.

[0027] The above technical solution involves deflecting the abutment plate, allowing the rotating shaft to rotate inside the adjusting rod, which in turn drives the abutment plate to deflect stably. This allows for further adjustment of the abutment plate's angle, bringing it parallel to the first lead plate layer and placing it in contact with the first lead plate layer to support it.

[0028] As a further description of the above technical solution:

[0029] A buffer layer is provided between the second lead plate layer and the thick steel plate strip, and the two first lead plate layers are tightly fitted without gaps.

[0030] Through the above technical means: the buffer layer is made of rubber. When the expansion bolts are installed, the buffer layer can absorb the inward pressure of the expansion bolts, thereby protecting the second lead plate layer. In addition, the two first lead plates are tightly attached, which can further increase the radiation protection performance.

[0031] This utility model has the following beneficial effects:

[0032] 1. This utility model, through the bending of the second lead plate layer, can wrap and protect the connection between the expansion bolt and the first lead plate layer, thereby effectively preventing radiation leakage. At the same time, by using angle iron as a support for the ceiling threaded rod, it also solves the problem of ceiling installation and increases the convenience of installation.

[0033] 2. This utility model, through the cooperation of the rotating component and the abutment plate, allows for the adjustment of the abutment plate angle by rotating the worm gear, which in turn drives the connecting rod to rotate via the worm wheel. This adjustment, in turn, drives the adjusting rod and the abutment plate to deflect via the connecting rod, thus ensuring that the abutment plate abuts against the surface of the first lead plate layer. This provides support for the first lead plate layer. Furthermore, the self-locking property of the worm wheel and worm gear prevents the abutment plate from shifting downwards, increasing the stability of the support. Attached Figure Description

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Reference Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a radiation-proof ceiling installation node unit, comprising a concrete structural slab 1; the installation node unit further comprises a first lead plate layer 2, an angle iron 3, and a second lead plate layer 5;

[0042] Two first lead plate layers 2 are stacked and laid flat on the bottom surface of the concrete structure slab 1. Angle iron 3 is fixedly installed on the bottom surface of the first lead plate layer 2 by expansion bolts. The second lead plate layer 5 is fixedly installed on the inside of the angle iron 3 by expansion bolts. A thick steel plate pressure strip is provided at the connection between the expansion bolt and the second lead plate layer 5. The extended end of the expansion bolt and the thick steel plate pressure strip are located on the inside of the second lead plate layer 5.

[0043] Two fixed seats 4 are fixedly connected to one side of the angle iron 3. A connecting rod 13 is rotatably installed on the inner side of the two fixed seats 4. A rotating assembly 12 is provided between the two connecting rods 13. The bottom surface of the first lead plate layer 2 abuts against two abutting plates 9.

[0044] Specifically, the use of two lead plate layers (2) significantly enhances indoor radiation protection. Both the first lead plate layer 2 and the second lead plate layer 5 are 2mm thick. Due to lead's high density (approximately 11.34 g / cm³), radiation particles are more likely to collide with lead atoms as they propagate through the lead plate. Each collision reduces the particle's energy or alters its direction of propagation. After multiple collisions, the energy of the radiation particles gradually decreases, eventually being absorbed or scattered by the lead plate, thus achieving radiation protection. Using lead plates as radiation shielding material is a common industry practice; therefore, the specific principles of lead plates will not be elaborated upon here. The expansion bolts pass sequentially through the thick steel plate strip, the second lead plate layer 5, the angle iron 3, and the first lead plate layer 5. The lead plate layer 2, therefore, can be fixedly installed at the bottom of the concrete structure slab 1 by the angle iron 3, the first lead plate layer 2, the second lead plate layer 5 and the steel plate pressure strip by the expansion bolts, ensuring the stability of the installation. The thick steel plate pressure strip can evenly distribute the pressure generated by the expansion bolts to the surface of the connected object, avoiding excessive local pressure that could damage the surface of the object, and increasing the protection of the second lead plate layer 5 during installation. The abutment plate 9 abuts against the bottom surface of the first lead plate layer 2, so the abutment plate 9 can support the first lead plate layer 2 and prevent the first lead plate layer 2 from bending due to the excessive spacing of the angle iron 3.

[0045] Reference Figure 1 and Figure 3The second lead plate layer 5 is bent and one side of the second lead plate layer 5 is in contact with the first lead plate layer 2, and the first lead plate layer 2 and the second lead plate layer 5 are fixedly bonded together; one end of the expansion bolt passes through the two first lead plate layers 2 and extends into the interior of the concrete structure slab 1, and the surface of the expansion bolt is coated with an anti-corrosion coating.

[0046] Specifically, the bottom ends of the thick steel plate strip and expansion bolts are placed inside the second lead plate layer 5, and the second lead plate layer 5 is bent to prevent radiation from leaking through the connection between the expansion bolts and the multi-layer structure, thereby enhancing the radiation protection performance. The second lead plate layer 5 is bonded to the surface of the first lead plate layer 2 with strong adhesive, thus increasing the sealing and stability of the connection between the second lead plate layer 5 and the first lead plate layer 2.

[0047] Reference Figure 4 The rotating assembly 12 includes a worm gear 1202 and a worm 1201. The worm gear 1202 is fixedly installed between two connecting rods 13, and the worm 1201 is located at the bottom of the worm gear 1202. The worm gear 1202 and the worm 1201 are connected by meshing. A connecting seat 6 is provided on one side of the angle iron 3. A turning block 11 is provided on the outer surface of the connecting seat 6. One end of the turning block 11 is connected to the worm 1201. The worm gear 1202 and the worm 1201 are located inside the connecting seat 6. A connecting rod 7 is provided on the inner side of the two fixed seats 4. One end of the connecting rod 7 is fixedly installed on the surface of the connecting rod 13. A rotating shaft 10 is rotatably installed at the end of the connecting rod 7. Adjusting rods 8 are fixedly connected to both ends of the rotating shaft 10. A stop plate 9 is fixedly installed on the top surface of the adjusting rod 8.

[0048] Specifically, the adjusting rod 8 is rotatably mounted on the end of the connecting rod 7 via the rotating shaft 10, thus deflecting the abutment plate 9. The abutment plate 9 rotates at the end of the connecting rod 7 via the rotating shaft 10, thereby adjusting its position. In actual use, the position of the abutment plate 9 can be adjusted to be parallel to the first lead plate layer 2. By rotating the worm gear 1201, the worm gear 1201 can drive the worm wheel 1202 to rotate, and the worm wheel 1202 can drive the connecting rods 13 on both sides to rotate. The connecting rods 13 can drive the connecting rod 7 to deflect, and the connecting rod 7 can drive the abutment plate 9 to deflect in a lifting manner, thereby pressing the abutment plate 9 against the first lead plate layer 2. When the abutment plate 9 abuts against the bottom surface of the first lead plate layer 2, it can support the first lead plate layer 2. Furthermore, the self-locking property of the worm gear 1202 and worm 1201 can prevent the connecting rod 13 from reversing, thereby ensuring the position of the abutment plate 9 and enhancing the stability of the support for the first lead plate layer 2. In actual use, the position of the angle iron 3 can be reasonably arranged according to the degree and width of the space. When the distance between two adjacent angle irons 3 is too large, the abutment plate 9 can support the first lead plate layer 2, preventing the first lead plate layer 2 from bending due to the excessive distance between the support points, thus affecting the protective performance.

[0049] Reference Figure 1, Figure 2 and Figure 3 A buffer layer is provided between the second lead plate layer 5 and the thick steel plate strip, and the two first lead plate layers 2 are tightly fitted without gaps.

[0050] Specifically, the buffer layer is made of rubber pads, which can buffer the pressure when the expansion bolts are connected, preventing excessive tightening force from damaging the second lead plate layer 5. The tight fit between the two first lead plate layers 2 can enhance the radiation protection effect of the first lead plate layer 2.

[0051] Working principle: When using this device, the two first lead plate layers 2 can be tightly connected and the expansion bolts are driven into the interior of the concrete structure slab 1 in sequence, passing through the thick steel plate gasket, the second lead plate layer 5, the angle iron 3 and the first lead plate layer 2 in sequence. In this way, the angle iron 3 can be fixedly installed at the bottom of the first lead plate layer 2, and the first lead plate layer 2 can be fixedly installed at the bottom of the concrete structure slab 1. By bending the second lead plate layer 5, the contact of the expansion bolts can be protected, preventing radiation from leaking outward through the contact between the expansion bolts and the structure.

[0052] By rotating the screwing block 11, the screwing block 11 drives the worm gear 1201 to rotate, the worm gear 1201 drives the worm wheel 1202 to rotate, the worm wheel 1202 drives the connecting rods 13 on both sides to rotate, the connecting rods 13 drive the connecting rod 7 to deflect, the connecting rod 7 drives the adjusting rod 8 at the end to deflect, the adjusting rod 8 drives the abutment plate 9 to deflect. By deflecting the abutment plate 9, the rotating shaft 10 rotates inside the connecting rod 7, which can further adjust the angle of the abutment plate 9 to make it parallel to the first lead plate layer 2. By continuously rotating the worm gear 1201, the abutment plate 9 can be pressed against the bottom surface of the first lead plate layer 2, ensuring the stability of the first lead plate layer 2. When this device is used, it enhances the radiation protection performance and also ensures the stability of the installation of the first lead plate layer 2.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
