Description

Technical Field

[0001] This utility model relates to the field of concrete wall construction and reinforcement technology, and in particular to a screw rod for reinforcing radiation-proof concrete walls, which can meet the integrated needs of wall reinforcement and radiation protection in radiation-prone areas. Background Technology

[0002] Currently, the reinforcement of ultra-thick and ultra-high concrete walls mostly uses conventional bolts with a single washer for positioning and reinforcement. The bolt structure is simple, only providing basic connection and support functions, and has not been designed and optimized for the "ultra-thick and ultra-high" structural characteristics of the wall or the potential radiation protection requirements. During the reinforcement process, it relies on ordinary connectors, which are not stable enough for positioning on both sides of the wall. The bolts are prone to displacement due to the pressure of wall pouring, and there is no special radiation protection structure design, which cannot meet the usage requirements in scenarios with radiation protection needs.

[0003] In other words, the existing technology has the following main defects: (1) Poor positioning stability: conventional screws with a single washer cannot adapt to the pouring pressure of ultra-thick and ultra-high concrete walls, and the screw end is prone to deflection, resulting in low wall pouring accuracy; (2) No radiation protection function: existing screws do not integrate radiation protection structure. In the construction of concrete walls involving radiation areas (such as specific industrial plants, medical facilities, etc.), an additional radiation protection layer is required, which increases the construction process and cost, and the radiation protection effect is easily affected by the construction coordination; (3) Insufficient adaptability: for ultra-thick walls, the support strength and length of conventional screws are poorly adapted, and they cannot effectively disperse the lateral pressure during wall pouring, which can easily lead to screw bending or breakage, thereby affecting the overall reinforcement effect of the wall. Utility Model Content

[0004] The purpose of this utility model is to provide a screw rod for reinforcing radiation-proof concrete walls, which has high positioning accuracy, integrated radiation protection function, high reinforcement strength, and strong adaptability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A screw rod for reinforcing radiation-proof concrete walls includes: a screw rod body, a positioning component, a radiation-proof component, and a heavy-duty mountain-shaped clamp; The radiation protection component is sleeved on and fixed in the middle area of ​​the screw body; the positioning component has multi-level gaskets, and the multi-level gaskets are installed at both ends of the screw body and respectively fit the outer side of the template on both sides of the wall; the heavy-duty mountain-shaped clips are sleeved on the outer side of the multi-level gaskets at both ends of the screw body, and the heavy-duty mountain-shaped clips tightly clamp the template.

[0006] In practical applications, the radiation protection component includes multiple radiation protection steel sheets, which are evenly spaced and fitted onto the central region of the screw body.

[0007] The spacing between adjacent radiation-shielding steel sheets is 15-20cm.

[0008] Specifically, the radiation-shielding steel sheet is connected and fixed to the screw body by welding.

[0009] Furthermore, the number of radiation-shielding steel sheets is set to 3-5 sheets depending on the radiation protection level.

[0010] Furthermore, the multi-level gaskets adopt a stepped structure, and the appropriate gasket level is selected according to the template thickness.

[0011] Furthermore, the screw body is made of high-strength alloy steel, and the appropriate length is selected according to the thickness of the concrete wall.

[0012] Compared with existing technologies, the screw rod for reinforcing radiation-proof concrete walls described in this utility model has the following advantages: The screw rod for reinforcing radiation-proof concrete walls provided by this utility model uses stepped multi-level gaskets to adapt to the outer templates of walls of different thicknesses, thereby achieving precise positioning at both ends of the screw rod body. This effectively avoids positioning deviation caused by differences in template thickness, thus effectively improving the pouring accuracy of ultra-thick and ultra-high walls. Radiation-proof steel sheets (referring to the structure of water-stop steel plates) are used to form an integrated radiation-proof barrier, eliminating the need for additional radiation-proof layers and simplifying the construction process. The number of radiation-proof steel sheets can be adjusted according to the protection level to adapt to different radiation scenarios. Heavy-duty mountain-shaped clamps enhance the clamping force on the templates. Combined with the high-strength alloy steel screw rod body, this effectively disperses the lateral pressure during the pouring of ultra-thick and ultra-high walls, thus effectively preventing the screw rod body from bending or breaking, further improving the reinforcement stability.

[0015] For ease of understanding, the following description, in conjunction with the accompanying drawings, provides a detailed description of the screw rod for reinforcing radiation-proof concrete walls provided in the embodiments of this utility model.

[0016] This utility model embodiment provides a screw rod for reinforcing radiation-proof concrete walls, such as... Figure 1 As shown, it includes: screw body 1, positioning assembly (not shown in the figure), radiation shielding assembly 2, and heavy-duty mountain-shaped clamp 3; Radiation shielding component 2 is fitted and fixed in the middle area of ​​screw body 1; positioning component has multi-level gaskets, which are installed at both ends of screw body 1 and respectively fit against the outer side of template 4 on both sides of the wall; heavy-duty mountain-shaped clips 3 are fitted on the outer side of the multi-level gaskets at both ends of screw body 1, and the heavy-duty mountain-shaped clips 3 tightly clamp template 4 (the heavy-duty mountain-shaped clips 3 are tightened with the end nuts of screw body 1 by a wrench, and cooperate with screw body 1 to enhance the fixing stability).

[0017] Compared with the prior art, the screw rod for reinforcing radiation-proof concrete walls described in this embodiment of the invention has the following advantages: The radiation-resistant concrete wall reinforcement screw provided in this embodiment utilizes stepped multi-level gaskets to adapt to wall templates of different thicknesses, achieving precise positioning at both ends of the screw body. This effectively avoids positioning deviations caused by differences in template thickness, thereby significantly improving the pouring accuracy of ultra-thick and ultra-high walls. Radiation-resistant steel sheets (similar to the water-stop steel plate structure) are used to form an integrated radiation-resistant barrier, eliminating the need for additional radiation-resistant layers and simplifying construction procedures. The number of radiation-resistant steel sheets can be adjusted according to the protection level to adapt to different radiation scenarios. Heavy-duty mountain-shaped clamps enhance the clamping force on the template. Combined with the high-strength alloy steel screw body, this effectively disperses the lateral pressure during ultra-thick and ultra-high wall pouring, preventing the screw body from bending or breaking, further enhancing reinforcement stability.

[0018] In practical applications, such as Figure 1 As shown, the radiation shielding component 2 may include multiple radiation shielding steel sheets, and the multiple radiation shielding steel sheets may preferably be uniformly spaced and sleeved in the middle region of the screw body 1.

[0019] Among them, such as Figure 1 As shown, the spacing between adjacent radiation shielding steel sheets can be 15-20cm.

[0020] Specifically, such as Figure 1 As shown, the aforementioned radiation-shielding steel sheet and the screw body 1 can be connected and fixed by welding, ensuring that the gap is filled tightly, thereby forming a continuous and effective radiation-shielding barrier.

[0021] Furthermore, such as Figure 1 As shown, the number of the aforementioned radiation-shielding steel sheets can be set to 3-5 sheets depending on the radiation protection level.

[0022] Furthermore, such as Figure 1As shown, the multi-level gaskets can adopt a stepped structure (the stepped structure of the multi-level gaskets can offset the thickness difference of the template 4 and ensure that the screw body 1 is accurately positioned without offset), and the appropriate gasket level can be selected according to the template thickness. That is, the positioning height can be adjusted according to the thickness of the template on the outside of the wall. At the same time, it can effectively ensure that the multi-level gaskets and the screw body are tightly connected by threads and there is no loosening.

[0023] Furthermore, such as Figure 1 As shown, the screw body 1 can be made of high-strength alloy steel, and the appropriate length can be selected according to the thickness of the concrete wall to effectively ensure the support strength.

[0024] During installation, based on the construction drawings of the ultra-thick and ultra-high concrete wall, the installation position of the screw body 1 is determined using a positioning instrument, and installation holes are opened at corresponding positions on the templates 4 on both sides of the wall. The assembled screw body 1 is passed through the installation holes of the template 4, so that the radiation protection component 2 in the middle is located in the preset radiation protection area inside the wall, and the positioning components at both ends are respectively attached to the outer side of the templates 4 on both sides of the wall. Heavy-duty U-shaped clips 3 are fitted on the outer side of the multi-level gaskets at both ends of the screw body 1. The nuts at the ends of the screw body 1 are tightened with a wrench to make the heavy-duty U-shaped clips 3 tightly clamp the template 4. The stepped structure of the multi-level gaskets is used to offset the thickness difference of the template 4, ensuring that the screw body 1 is accurately positioned without deviation. After the screw installation is completed, concrete pouring is carried out. During the pouring process, the stability of the screw body 1 is monitored. If the formwork 4 moves slightly, the clamping force of the heavy-duty mountain-shaped clamp 3 is adjusted to correct it. After the concrete curing is completed, the screw body 1 is either retained or removed according to actual needs. If it is to be retained, the end of the screw body 1 is treated with anti-corrosion. If it is to be removed, the nut, heavy-duty mountain-shaped clamp 3 and multi-stage gasket are removed, and the screw body 1 is cut off with a special tool. The cut-off point is then sealed and treated with radiation protection.

[0025] In summary, the screw rod for reinforcing radiation-proof concrete walls provided in this embodiment of the invention has the following advantages: 1. High positioning accuracy: The multi-level gasket design at both ends can flexibly adapt to templates of different thicknesses. Combined with the clamping effect of the heavy-duty mountain-shaped clamp, it ensures that the main body of the screw does not shift during the wall pouring process, and the forming accuracy of ultra-thick and ultra-high walls is improved by more than 30%. II. Integrated Radiation Protection Function: The intermediate radiation protection component integrates reinforcement and radiation protection, eliminating the need for additional radiation protection layers, increasing construction efficiency by 25%, and ensuring stable radiation protection performance that meets the standards for use in radiation-affected areas. 3. High reinforcement strength: The high-strength screw body, combined with the heavy-duty mountain-shaped clamp, can withstand the lateral pouring pressure of ultra-thick and ultra-high concrete walls, reducing the screw breakage rate to below 0.5%, and significantly improving the overall structural stability of the wall. IV. High adaptability: The length of the main body of the screw can be adjusted according to the wall thickness, and the number of radiation shielding steel sheets can be adjusted according to the radiation level. It is suitable for the construction of ultra-thick and ultra-high concrete walls of different specifications and protection requirements, and has a wide range of applicable scenarios.
