Description

Technical Field

[0001] This invention belongs to the field of lead plate construction technology, and in particular relates to a method for constructing lead plates for operating room walls. Background Technology

[0002] In hospital CT rooms, DR rooms, MRI rooms, and other machine rooms, there are varying degrees of nuclear radiation and electromagnetic radiation. The walls of these rooms are mostly lightweight partitions or infill walls, which cannot prevent radiation from spreading outwards. To prevent the nuclear radiation and electromagnetic radiation in these rooms from spreading outwards and causing harm to people, lead plates are usually installed on the walls of these rooms for protection.

[0003] The following defects exist in the current construction process of lead plates: the length of the keel and lead plate is prepared in advance according to the floor height of the operating room. The keel is relatively long and is directly mounted on the wall for positioning, which requires high operational skills. The lead plate is fixed to the keel by welding and bolts, which is laborious and inconvenient and requires high construction intensity. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned technical problems existing in the prior art and to provide a method for constructing lead plates for operating room walls. The method is simple, efficient, and easy to operate, greatly reducing the number of bolts used. It is labor-saving and convenient, and the layered arrangement from bottom to top is easy to control and ensures construction quality.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A method for installing lead plates for operating room walls, characterized by the following steps:

[0007] (a) Construction line marking: Draw the height limit line of the main keel on the wall according to the design and construction drawings;

[0008] (b) Arrange the pads:

[0009] ① Connect the straight pads one by one to obtain a combination of two long pads and a combination of two short pads;

[0010] ② Install L-shaped pads at both ends of the long pad assembly, and then install the short pad assembly between the two L-shaped pads, so that the two long pad assemblies and the two short pad assemblies form a circle.

[0011] ③ Adjust the spacing between two adjacent straight pads so that the long pad assembly meets the depth requirements of the operating room and the short pad assembly meets the bay requirements of the operating room. Then, attach the L-shaped pad to the corner of the wall and attach the long pad assembly and the short pad assembly to the wall one by one.

[0012] (c) Laying out the keel and lead plates:

[0013] ① Insert the connector at the bottom of the main keel into the limiting groove on the straight pad, so that the main keel is limited on the straight pad, thus completing the arrangement of the first layer of main keel;

[0014] Insert the connector at the bottom of the corner keel into the limiting groove on the L-shaped pad, so that the corner keel is limited on the L-shaped pad, thus completing the arrangement of the first layer of corner keel.

[0015] ② Unfold the lead plate and insert the lead plate and pad strip into the side slot of the main keel from top to bottom, so that the lead plate and pad strip are limited between the two adjacent main keels on the left and right.

[0016] Insert the lead plate and pad into the side slot of the main keel and the side slot of the corner keel from top to bottom, so that the lead plate and pad are limited between the main keel and the corner keel.

[0017] ③ Insert the connector at the bottom of the next main keel into the slot of the first main keel, so that the main keel is confined to the first main keel, thus completing the arrangement of the second main keel;

[0018] Insert the connector at the bottom of the next corner keel into the slot of the first layer of corner keels, so that the corner keel is confined on the first layer of corner keels, thus completing the arrangement of the second layer of corner keels.

[0019] Then lead plates and pads are inserted between the corner keel and the main keel on the second layer, and between the main keels and the main keels.

[0020] ④ Install the main keel and corner keel first, then install the lead plate and pad strip, and carry out the construction layer by layer upwards until the last pad strip is flush with the top surface of the top main keel.

[0021] (d) Arrange the pressure plates:

[0022] ① Connect the straight pressure plates one by one to obtain a combination of two long pressure plates and a combination of two short pressure plates;

[0023] ② Lift up the long pressure plate assembly and the short pressure plate assembly, and insert the positioning block on the straight pressure plate from top to bottom into the groove of the uppermost main keel, so that the long pressure plate assembly and the short pressure plate assembly are limited on the uppermost main keel.

[0024] ③ Insert the limiting block at the bottom of the L-shaped pressure plate into the groove of the uppermost corner keel from top to bottom, so that the L-shaped pressure plate is limited on the uppermost corner keel;

[0025] Fastening bolts are installed between the side fixing block at the end of the L-shaped pressure plate and the side of the straight pressure plate to fix the L-shaped pressure plate to the long pressure plate assembly and the short pressure plate assembly.

[0026] Furthermore, in step (b) ①, the method for connecting the straight pads is as follows: insert the protrusion at one end of one straight pad into the hole at one end of another straight pad, so that the two straight pads are connected together. The connection is simple, and it can be used immediately after installation. It replaces the bolt fixing method, which is efficient, labor-saving and convenient.

[0027] The specific method in step (b) ② is as follows: fit the hole at one end of an L-shaped pad onto the protrusion at one end of the long pad assembly, insert the protrusion at one end of another L-shaped pad into the hole at the other end of the long pad assembly, so that the two L-shaped pads are installed at both ends of the long pad assembly. Then, align the protrusion at one end of the short pad assembly with the hole of an L-shaped pad, and align the hole at the other end of the short pad assembly with the protrusion of an L-shaped pad. The alignment is simple, replaces the bolt fixing method, has high construction efficiency, and is labor-saving and convenient.

[0028] The method for adjusting the spacing in step (b) ③ is as follows: slide each straight pad horizontally so that the protrusion of one straight pad does not come out of the hole of the adjacent straight pad, creating a gap between the adjacent straight pads, thus lengthening the long pad assembly and the short pad assembly, thereby adapting to the depth and opening size requirements of the operating room, and having strong adaptability.

[0029] Furthermore, both ends of the straight pad are provided with openings, and protrusions are provided inside the openings. The protrusions extend out of the openings, and a part of the protrusions is located inside the openings and welded to the straight pad, ensuring the installation strength of the protrusions.

[0030] Further, in step (c) ④, after the main keel arrangement reaches the designed height, the two straight pads at the doorway are cut so that the cut end of the straight pad is flush with the side of the main keel connected to the straight pad; then the protruding strip on the baffle is inserted into the side groove of the main keel, so that the baffle is installed on the side of the main keel, and the baffle is fixed to the main keel by welding. The baffle covers the side groove of the main keel to prevent people from hitting the groove and getting injured, thus providing simple protection; next, a pad is inserted between the two main keels so that the pad abuts against the top surface of the baffle. The baffle provides support for the pad, which facilitates the subsequent placement of the lead plate. The lead plate and pad are then inserted in sequence until the last installed pad is flush with the top surface of the uppermost main keel.

[0031] Furthermore, in step (c) ④, when the distance between the pad strip and the top surface of the uppermost main keel is less than the height of a lead plate, continue to insert pad strips until the last installed pad strip is flush with the top surface of the uppermost main keel. The stack of pad strips eliminates the height difference between the uppermost lead plate and the uppermost main keel. On the one hand, the stack of pad strips presses down on the uppermost lead plate to prevent it from moving upwards. On the other hand, it improves the overall integrity of the lead plate arrangement and avoids gaps of different sizes. The pad strips have low usage costs and are economical and practical.

[0032] Furthermore, step (d) is followed by step (e) caulking: rubber strips are inserted into the gap between two adjacent straight pads and fixed with adhesive. This prevents dust from entering the gap between the two adjacent straight pads, reducing the difficulty of cleaning. On the other hand, the rubber strips connect the two adjacent straight pads into one piece, preventing them from detaching freely and preventing the straight pads from shifting and squeezing the lead plate.

[0033] Furthermore, in step (c), the main keel has protrusions on both sides of the opposite sides, the corner keel has protrusions on both adjacent sides, and a side groove is formed between adjacent protrusions. The main keel has a through groove, and a connector is provided in the groove opening at one end of the through groove. The connector extends out of the groove opening, and the straight pad and the L-shaped pad are provided with limiting grooves corresponding to the connectors.

[0034] Furthermore, the method for connecting the straight pressure plates in step (d) is as follows: insert the fixing block at one end of one straight pressure plate into the sleeve hole at one end of another straight pressure plate, so that the two straight pressure plates are connected together. The connection is simple, and it can be used immediately after installation. It replaces the bolt fixing method, which has high construction efficiency and saves effort and is convenient.

[0035] Furthermore, both ends of the straight pressure plate are provided with sleeve holes, and a fixing block is provided inside the sleeve hole. The fixing block extends out of the sleeve hole, and a part of the fixing block is located inside the sleeve hole and welded to the straight pressure plate to ensure the installation strength of the protrusion.

[0036] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0037] 1. Both the long and short pad assemblies are composed of several straight pads inserted together, replacing bolt fixing. This method offers high construction efficiency, saves labor, and is convenient. The structure formed by the L-shaped pads and the long and short pad assemblies serves as the bottom load-bearing foundation, eliminating the impact of uneven ground and facilitating the subsequent installation and positioning of the keel. This greatly reduces construction difficulty and improves construction efficiency. The lengths of the long and short pad assemblies are flexibly adjustable to meet the depth and span requirements of the operating room, demonstrating strong adaptability.

[0038] 2. The main keel is inserted on the straight pad, and the pad strip and lead plate are inserted between two adjacent main keels. Since the lead plate is relatively soft, the pad strip limits the distance between two adjacent main keels, which can prevent the main keel from squeezing the lead plate as it moves laterally with the straight pad, thus ensuring the installation quality of the lead plate and improving the connection reliability between two adjacent straight pads, making them unable to separate freely.

[0039] 3. The height difference between the top lead plate and the top main keel is eliminated by stacking pad strips. On the one hand, the pad strips press down on the top lead plate to prevent it from moving upwards. On the other hand, the overall integrity of the lead plate arrangement is improved, avoiding gaps of different sizes. The pad strips are low in cost and economical.

[0040] 4. The L-shaped pressure plate connects the long and short pressure plate assemblies into a single unit, creating a mutually restraining relationship that prevents free movement. This prevents the long and short pressure plate assemblies from detaching from the main keel. The fixing block and sleeve hole engage, ensuring that adjacent straight pressure plates do not separate due to relative movement. This guarantees the assembly reliability of the long and short pressure plate assemblies. Furthermore, the long and short pressure plate assemblies press down on the uppermost pad and the uppermost main keel, preventing them from moving upwards. The upper main keel prevents the lower main keel from moving upwards, and the upper pad prevents the lower lead plate from moving upwards. From top to bottom, the pressure is gradually tightened, preventing free detachment. This ensures reliable assembly, high stability, significantly reduces the number of bolts used, and improves construction efficiency, saving labor and time. Attached Figure Description

Detailed Implementation

[0052] like Figures 1 to 9 As shown, the present invention provides a method for constructing lead plates for operating room walls, comprising the following steps:

[0053] (a) Construction line marking: Draw the height limit line of the main keel on the wall according to the design and construction drawings;

[0054] (b) Arrangement of pads: The straight pad 1 is provided with a limiting groove 2, and both ends of the straight pad 1 are provided with holes 3. A protrusion 4 is provided in the hole 3, and a part of the protrusion 4 is located in the hole 3 and welded to the straight pad 1 to ensure the installation strength of the protrusion 4. The structure of the L-shaped pad 5 is the same as that of the straight pad 1, but the shape is different.

[0055] ① Connect the straight pads 1 one by one. Insert the protrusion 4 at one end of one straight pad 1 into the hole 3 at one end of another straight pad 1, so that the two straight pads 1 are connected together to obtain a combination of two long pads and a combination of two short pads. The connection is simple, and it can be used immediately after installation. It replaces the bolt fixing method, which has high construction efficiency and saves effort and is convenient.

[0056] ② Fit the hole 3 at one end of an L-shaped pad 5 onto the protrusion 4 at one end of the long pad assembly. Insert the protrusion 4 at one end of another L-shaped pad 5 into the hole 3 at the other end of the long pad assembly, so that the two L-shaped pads 5 are installed at both ends of the long pad assembly. Then, align the protrusion 4 at one end of the short pad assembly with the hole 3 of an L-shaped pad 5, and align the hole 3 at the other end of the short pad assembly with the protrusion 4 of an L-shaped pad 5, so that the two long pad assemblies and the two short pad assemblies form a ring. The connection is simple, replaces the bolt fixing method, has high construction efficiency, and is labor-saving and convenient.

[0057] ③ Adjust the spacing between two adjacent straight pads 1. The specific method is as follows: slide each straight pad 1 horizontally so that the protrusion 4 of one straight pad 1 does not come out of the hole 3 of the adjacent straight pad 1. A gap is generated between the adjacent straight pads 1, which lengthens the long pad assembly and the short pad assembly. The long pad assembly meets the depth size requirements of the operating room, and the short pad assembly meets the opening size requirements of the operating room. It has strong adaptability.

[0058] Then, the L-shaped pad 5 is attached to the corner of the wall, and the long pad assembly and the short pad assembly are attached to the bottom of the wall one by one. The structure formed by the L-shaped pad 5, the long pad assembly, and the short pad assembly serves as the bottom load-bearing foundation, eliminating the impact of uneven ground, facilitating the subsequent installation and positioning of the keel, greatly reducing the construction difficulty, and improving construction efficiency.

[0059] (c) Arrangement of keel and lead plate: Both sides of the main keel 6 are provided with protrusions 7, and both adjacent sides of the corner keel 11 are provided with protrusions 7. Side grooves 8 are formed between adjacent protrusions 7. The main keel 6 has a through groove, and a connector 10 is provided in the groove opening 9 at one end of the through groove. The connector 10 extends out of the groove opening 9, and a portion of the connector 10 is located inside the through groove and welded to the main keel 6 to ensure the installation strength of the connector 10. The limiting groove 2 corresponds to the connector 10.

[0060] ① Insert the connector 10 at the bottom of the main keel 6 into the limiting groove 2 on the straight pad 1, so that the main keel 6 is limited on the straight pad 1, completing the arrangement of the first layer of main keel 6. Insert the connector 10 at the bottom of the corner keel 11 into the limiting groove 2 on the L-shaped pad 5, so that the corner keel 11 is limited on the L-shaped pad 5, completing the arrangement of the first layer of corner keel 11. The main keel 6 and corner keel 11 are quickly positioned, with low construction difficulty and high efficiency.

[0061] ② Unfold the lead plate 12, and insert the lead plate 12 and the pad strip 13 sequentially from top to bottom into the side slots 8 of the main keel 6, so that the lead plate 12 and the pad strip 13 are limited between the two adjacent main keels 6. Then, insert the lead plate 12 and the pad strip 13 sequentially from top to bottom into the side slots 8 of the main keel 6 and the side slots 8 of the corner keel 11, so that the lead plate 12 and the pad strip 13 are limited between the main keel 6 and the corner keel 11. Because the lead plate 12 is relatively soft, the pad strip 13 limits the distance between the two adjacent main keels 6, which can prevent the main keel 6 from squeezing the lead plate 12 as it moves laterally with the straight pad plate 1, ensuring the installation quality of the lead plate 12, improving the connection reliability between the two adjacent straight pad plates 1, and preventing them from separating freely.

[0062] ③ Insert the connector 10 at the bottom of the next main keel 6 into the slot 9 of the first main keel 6, so that the main keel 6 is limited to the first main keel 6, thus completing the arrangement of the second main keel 6; insert the connector 10 at the bottom of the next corner keel 11 into the slot 9 of the first corner keel 11, so that the corner keel 11 is limited to the first corner keel 11, thus completing the arrangement of the second corner keel 11; the stacking height of the main keel 6 and the corner keel 11 is flexible and variable, which can be used in operating rooms with different floor heights, and can be used immediately after installation, with strong adaptability.

[0063] Then lead plates 12 and pads 13 are inserted between the corner keel 11 and the main keel 6 on the second layer, and between the main keels 6 and the main keel 6.

[0064] ④ Following the order of first installing the main keel 6 and corner keel 11, and then installing the lead plate 12 and pad strip 13, construction is carried out layer by layer upwards. The layered arrangement allows for timely adjustments and ensures construction quality.

[0065] After the main keel 6 reaches the designed height, the two straight pads 1 at the doorway are cut so that the cut end of the straight pad 1 is flush with the side of the main keel 6 connected to it. Then, the protrusion 15 on the baffle 14 is inserted into the side groove 8 of the main keel 6, so that the baffle 14 is installed on the side of the main keel 6. The baffle 14 is fixed to the main keel 6 by welding. The baffle 14 covers the side groove 8 of the main keel 6 to prevent people from hitting it and getting injured, thus providing simple protection. Next, a pad strip 13 is inserted between the two main keels 6 so that the pad strip 13 abuts against the top surface of the baffle 14. The baffle 14 provides support for the pad strip 13, which facilitates the subsequent placement of the lead plate 12. Then, the lead plate 12 and the pad strip 13 are inserted in sequence.

[0066] When the distance between the pad strip 13 and the top surface of the uppermost main keel 6 is less than the height of a lead plate 12, continue to insert the pad strip 13 until the last installed pad strip 13 is flush with the top surface of the uppermost main keel 6. The stack of pad strips 13 eliminates the height difference between the uppermost lead plate 12 and the uppermost main keel 6. On the one hand, the stack of pad strips 13 presses down on the uppermost lead plate 12 to prevent it from moving upward. On the other hand, it improves the overall integrity of the arrangement of the lead plates 12 and avoids gaps of different sizes. The pad strip 13 has low usage cost and is economical and practical.

[0067] (d) Arrangement of pressure plates: The straight pressure plate 16 is provided with positioning blocks 17. Both ends of the straight pressure plate 16 are provided with sleeve holes 18. Fixing blocks 19 are provided in the sleeve holes 18. The fixing blocks 19 extend out of the sleeve holes 18. A part of the fixing blocks 19 is located in the sleeve holes 18 and welded and fixed to the straight pressure plate 16 to ensure the installation strength of the protrusion 4. The bottom of the L-shaped pressure plate 20 is provided with a limiting block 21, which corresponds to the groove 9. Both ends of the L-shaped pressure plate 20 are provided with side fixing blocks 22. The side fixing blocks 22 are provided with mounting countersunk holes 24. The side of the straight pressure plate 16 is provided with several screw holes 25.

[0068] ① Connect the straight pressure plates 16 one by one, insert the fixing block 19 at one end of one straight pressure plate 16 into the sleeve hole 18 at one end of another straight pressure plate 16, so that the two straight pressure plates 16 are connected together to obtain a combination of two long pressure plates and a combination of two short pressure plates. The connection is simple, and it can be used immediately after installation. It replaces the bolt fixing method, which has high construction efficiency and saves effort and is convenient.

[0069] ② Lift the long pressure plate assembly and the short pressure plate assembly, and insert the positioning block 17 on the straight pressure plate 16 from top to bottom into the groove 9 of the uppermost main keel 6, so that the long pressure plate assembly and the short pressure plate assembly are limited on the uppermost main keel 6. The installation is simple, replaces the bolt fixing method, and the construction is quick.

[0070] ③ Insert the limiting block 21 at the bottom of the L-shaped pressure plate 20 into the groove 9 of the uppermost corner keel 11 from top to bottom, so that the L-shaped pressure plate 20 is limited on the uppermost corner keel 11. The positioning is simple, replacing the bolt fixing method, and the construction is quick.

[0071] Fastening bolts 26 are installed between the side fixing block 22 and the side of the straight pressure plate 16 to fix the L-shaped pressure plate 20 to the long pressure plate assembly and the short pressure plate assembly.

[0072] The L-shaped pressure plate 20 connects the long pressure plate assembly and the short pressure plate assembly into a single unit, forming a mutually restraining relationship that prevents free movement. This prevents the long and short pressure plate assemblies from detaching from the main keel 6. The fixing block 19 and the sleeve hole 18 engage, ensuring that adjacent straight pressure plates 16 do not move relative to each other and separate. This guarantees the assembly reliability of the long and short pressure plate assemblies. The long and short pressure plate assemblies press down on the uppermost pad strip 13 and the uppermost main keel 6, preventing them from moving upwards. The upper main keel 6 prevents the lower main keel 6 from moving upwards, and the upper pad strip 13 prevents the lower lead plate 12 from moving upwards. From top to bottom, the plates are pressed down step by step, preventing them from detaching freely. This ensures reliable assembly, high stability, and significantly reduces the number of bolts used, resulting in high construction efficiency and ease of use.

[0073] (e) Sealing: Rubber strips 23 are inserted into the gap between two adjacent straight pads 1 and fixed with adhesive. On the one hand, this prevents dust from entering the gap between the two adjacent straight pads 1, reducing the difficulty of cleaning. On the other hand, the rubber strips 23 connect the two adjacent straight pads 1 into one, making them unable to separate freely, and prevents the straight pads 1 from shifting and squeezing the lead plate 12.

[0074] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
