Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically a construction device and method for a radiation-proof computer room. Background Technology

[0002] With the rapid development of medical imaging technology, medical linear accelerators, as a device for treating tumors, are also widely used in surgical radiotherapy. However, due to the large energy output and strong radiation of medical linear accelerators, while improving the quality of surgery, they also bring negative impacts. The most serious of these is the problem of X-ray radiation pollution in the operating room. To prevent the harmful effects of linear accelerator radiation on the human body, the roof and walls of the linear accelerator room are made of ultra-thick, large-volume concrete structures, which involve complex construction processes and require a specialized construction organization design in advance to meet the design requirements.

[0003] Due to the large volume, ultra-thickness, and high unit density of radiation-shielding concrete structures, high-rise formwork engineering is involved, requiring the formwork system to have sufficient load-bearing capacity, rigidity, and stability. To ensure the safety of the formwork engineering, tie bolts are installed to reinforce the formwork engineering on top of the traditional formwork and support system. Furthermore, radiation-shielding concrete structures inevitably require through-wall sleeves or pre-reserved structural holes to allow pipelines such as water pipes and cables to pass through during subsequent construction. These tie bolt holes, through-wall sleeves, and pre-reserved structural holes become weak points in the entire radiation-shielding system, posing a significant risk of radiation leakage.

[0004] Chinese patent application CN113638598B discloses a tie bolt and construction method for pre-reserved labyrinthine holes in radiation-proof concrete. The key technical points are: combining through-wall sleeves, pre-reserved structural holes, and tie bolt structures involved in radiation-proof concrete formwork to reduce the number of weak points in the radiation-proof concrete structure, fundamentally reducing the risk of radiation leakage; the pre-embedded sleeve adopts a non-straight-through zigzag structure, with an inner coating of radiation-proof material, effectively preventing radiation leakage without affecting the normal function of the through-wall sleeve or pre-reserved structural hole; protective sleeves are installed at the ends of the pre-embedded sleeves, providing excellent grout stopping and limiting effects; the installation efficiency is improved by using rebar connectors, allowing for assembly line operations and shortening the construction period; the tie bolts for the pre-reserved labyrinthine holes in radiation-proof concrete, together with conventional pre-embedded tie bolts, greatly improve the overall stress rationality of the radiation-proof concrete structural formwork system, ensuring the safety of tall formwork projects.

[0005] However, the above-mentioned technologies often have the following drawbacks: The existing technology of pre-reserved maze-like hole tie bolt structure combines the through-wall sleeve, the pre-reserved hole in the structure and the tie bolt, thereby reducing the number of weak parts in the radiation-proof concrete structure. However, after the recyclable screw is removed, the pre-embedded sleeve needs to be filled with radiation-proof material. If the pipeline is damaged and needs to be replaced, the radiation-proof material will fix the pipeline inside the pre-embedded sleeve, which will make it difficult to replace the pipeline and seriously affect the secondary wiring work.

[0006] Therefore, the present invention provides a construction device and method for a radiation-proof computer room. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0008] The technical solution adopted by the present invention to solve its technical problem is as follows: A construction device for a radiation protection room, comprising a template, a pre-embedded sleeve, a rebar connector, a pre-embedded screw rod, a recyclable screw rod, a recyclable bolt joint, a waterstop plate, a wooden support, a fastener, and a nut; the pre-embedded screw rod and the recyclable screw rod are all connected to the rebar connector by threads; the recyclable bolt joint is connected to the pre-embedded screw rod by threads.

[0009] It also includes a filling sleeve; the filling sleeve is filled with radiation shielding material; the filling sleeve and the radiation shielding material are provided with through holes for pipelines to pass through; a fixing component is provided between the pre-embedded sleeve and the filling sleeve;

[0010] Existing technologies using pre-reserved maze-like hole tie-bolt structures combine wall sleeves, pre-reserved structural holes, and tie bolts to reduce the number of weak points in radiation-shielding concrete structures. However, this structure requires filling the pre-embedded sleeve with radiation-shielding material after the recyclable screw is removed. If the pipeline is damaged and needs replacement, the radiation-shielding material fixes the pipeline inside the pre-embedded sleeve, making replacement difficult and severely impacting secondary wiring. This invention removes the recyclable screw from the pre-embedded sleeve, passes the pipeline through it, and inserts two filler sleeves through the ends of the pipeline. The radiation-shielding material inside the filler sleeves then isolates the pipeline during subsequent use. When pipeline replacement is needed, the pipeline and filler sleeves are removed from the pre-embedded sleeve, and a new pipeline is reinstalled using the above method. This device provides effective radiation protection, facilitates pipeline replacement, improves the efficiency of secondary wiring, and benefits future maintenance.

[0011] Preferably, the inner side of the pre-embedded sleeve and the outer side of the filling sleeve are coated with an anti-radiation coating; by setting the anti-radiation coating, the radiation rays entering between the pre-embedded sleeve and the filling sleeve can be absorbed, further improving the anti-radiation effect of the device.

[0012] Preferably, the radiation shielding material inside the filling sleeve is radiation shielding rubber. Compared with other radiation shielding materials, such as high-density mortar, radiation shielding rubber is lightweight, easy to install, and has strong insulation capabilities, making it more suitable for the prefabrication construction of this device. By prefabricating and installing the radiation shielding rubber inside the filling sleeve in advance, in actual operation, it is only necessary to insert the filling sleeve into the pre-embedded sleeve, eliminating the need to fill the radiation shielding material on-site, further simplifying the construction process.

[0013] Preferably, the fixing component includes a joint groove formed inside the pre-embedded sleeve, and the joint groove is annular; a groove is formed at the end of the filling sleeve; a set of through grooves are evenly distributed between the groove and the outer side of the filling sleeve; a retaining strip is slidably connected inside the through groove; a bevel is provided at one end of the retaining strip protruding from the surface of the filling sleeve; a pressure plate is fixedly connected at one end of the retaining strip extending into the groove; a spring is fixedly connected between the pressure plate and the side wall of the groove; during the process of inserting the filling sleeve into the pre-embedded sleeve, the pre-embedded sleeve squeezes the bevels of multiple retaining strips, squeezing the retaining strips into the through groove and stretching the spring; when the through groove and the joint groove are aligned, under the action of the spring, the ends of multiple retaining strips are inserted into the joint groove, realizing the fixed installation between the filling sleeve and the pre-embedded sleeve, and the fixing process is convenient and quick.

[0014] Preferably, a movable ring is slidably connected inside the groove; a second spring is fixedly connected between the movable ring and the end of the groove; a connecting plate is fixedly connected to the side of the pressure plate away from the locking strip; a guide groove is opened on the surface of the connecting plate; a set of inclined guide blocks are evenly distributed on the side of the movable ring near the second spring; the inclined guide blocks correspond one-to-one with the connecting plate and pass through the inside of the guide groove; when the pipeline needs to be replaced, the movable ring is pulled outward, and then multiple inclined guide blocks slide inside the guide groove, using the inclined surface of the inclined guide blocks to press the connecting plate, and driving multiple locking strips to slide and converge towards the middle, thereby disengaging the locking strips from the joint groove, realizing the release and fixation between the filling sleeve and the pre-embedded sleeve, and then the filling sleeve can be removed.

[0015] Preferably, an annular groove is provided on the outer side of the filling sleeve; a water-stop ring is provided inside the annular groove, and the water-stop ring is made of a water-swellable material; by setting a water-stop ring between the filling sleeve and the pre-embedded sleeve, the water-stop ring expands when it comes into contact with water, preventing water from leaking through the gap between the two and improving the water-proof effect of the radiation-proof concrete.

[0016] Preferably, a stop block is fixedly connected inside the pre-embedded sleeve near the end of the filling sleeve; a pressure ring is provided at the end of the filling sleeve; a hollow elastic ring is fixedly connected between the filling sleeve and the pressure ring, and the elastic ring is corrugated; a set of air grooves are evenly distributed inside the radiation-shielding rubber; the air grooves and the elastic ring are interconnected by air pipes; in the design, the diameter of the through hole inside the radiation-shielding rubber can be appropriately increased to facilitate the smooth passage of the pipeline through the radiation-shielding rubber and reduce the difficulty of threading. During the process of inserting the filling sleeve into the pre-embedded sleeve, the stop block squeezes the elastic ring through the pressure ring, forcing the air inside the elastic ring into the multiple air grooves through the air pipes, causing the air grooves to expand. The expansion of the air grooves causes the radiation-shielding rubber to clamp the pipeline, which can fix the pipeline on the one hand, and reduce the gap between the radiation-shielding rubber and the pipeline on the other hand, preventing radiation rays from passing through this gap, and further improving the radiation protection effect of the device.

[0017] Preferably, a set of guide tubes are evenly distributed at the end of the filling sleeve; a guide rod is slidably connected inside the guide tube, and one end of the guide rod extending outside the guide tube is fixedly connected to the pressure ring; by setting multiple guide tubes and guide rods to slide in cooperation, the movement process of the pressure ring can be limited, so that when the stop block squeezes the pressure ring, the pressure ring always remains parallel to the end of the filling sleeve, thereby improving the squeezing efficiency of the pressure ring on the elastic ring.

[0018] A method for constructing a radiation-proof computer room, the method using the aforementioned construction device for a radiation-proof computer room, includes the following steps:

[0019] S1: Tie the wall panels and roof slab reinforcement, and arrange cooling pipes in the wall panel reinforcement and roof slab reinforcement. Use steel pipe coupler scaffolding to erect the internal frame according to the shape and internal space size of the computer room.

[0020] S2: Assembly of wall panels and roof panels, installation of embedded sleeves, rebar connectors, embedded bolts, recyclable bolts, recyclable bolt joints, waterstops, wooden supports, fasteners, and nuts;

[0022] S4: Remove templates, recyclable screws, recyclable bolt joints, wooden supports, fasteners, and nuts.

[0023] Preferably, the method further includes the following steps:

[0024] S5: Pass the pipeline through the inside of the pre-embedded sleeve, and pass both ends of the pipeline through the filling sleeve respectively. Then insert the filling sleeve into both ends of the pre-embedded sleeve respectively.

[0025] S6: The retaining strip is squeezed into the through groove by the pre-embedded sleeve. When the through groove is aligned with the joint groove, the spring drives the retaining strip to be inserted into the joint groove, thereby achieving the fixed installation between the filling sleeve and the pre-embedded sleeve.

[0026] The beneficial effects of this invention are as follows:

[0027] 1. The construction device and method for a radiation protection room described in this invention, when put into use and combined with the actual situation of the project, can meet the requirements of supporting concrete load and preventing horizontal displacement of wall formwork, while ensuring safety, reducing construction costs, and achieving significant social and economic benefits.

[0028] 2. The construction device and method for a radiation-proof computer room described in this invention involves removing a recyclable screw from inside a pre-embedded sleeve, first passing the pipeline through the pre-embedded sleeve, and then passing both ends of the pipeline through a filling sleeve. The two filling sleeves are then inserted into both ends of the pre-embedded sleeve. During subsequent use, the radiation-proof material inside the filling sleeves serves to isolate radiation. When the pipeline needs to be replaced, the pipeline and filling sleeves are removed from the pre-embedded sleeve, and a new pipeline is reinstalled according to the above method. This device provides effective radiation protection, facilitates pipeline replacement, improves the efficiency of secondary wiring, and is beneficial for later maintenance.

Pipeline. Detailed Implementation

[0042] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0043] Example 1: As Figures 1 to 7 As shown in the figure, a construction device for a radiation-proof computer room according to an embodiment of the present invention includes a template 1, a pre-embedded sleeve 2, a rebar connector 3, a pre-embedded screw rod 4, a recyclable screw rod 5, a recyclable bolt joint 6, a waterstop 7, a wooden support 8, a fastener 9, and a nut 10; the pre-embedded screw rod 4 and the recyclable screw rod 5 are both threadedly connected to the rebar connector 3; the recyclable bolt joint 6 is threadedly connected to the pre-embedded screw rod 4.

[0044] It also includes a filling sleeve 11; the filling sleeve 11 is filled with radiation shielding material; the filling sleeve 11 and the radiation shielding material are provided with through holes for the pipeline 32 to pass through; a fixing component is provided between the pre-embedded sleeve 2 and the filling sleeve 11;

[0045] The existing pre-reserved maze-hole tie-bolt structure combines the through-wall sleeve, pre-reserved structural holes, and tie bolts to reduce the number of weak points in the radiation-shielding concrete structure. However, after the recyclable screw 5 is removed, radiation-shielding material needs to be filled inside the pre-embedded sleeve 2. If the pipeline 32 is damaged and needs to be replaced, the radiation-shielding material will fix the pipeline 32 inside the pre-embedded sleeve 2, making it difficult to replace the pipeline 32 and seriously affecting the secondary wiring work. The present invention removes the recyclable screw 5 from the pre-embedded sleeve 2 and then first lays the pipeline 32 through the pre-embedded sleeve 2. The pipeline 32 is inserted through the pre-embedded sleeve 2, and both ends of the pipeline 32 are passed through a filling sleeve 11. The two filling sleeves 11 are then inserted into both ends of the pre-embedded sleeve 2. In subsequent use, the radiation-shielding material inside the filling sleeves 11 will isolate radiation. When the pipeline 32 needs to be replaced, the pipeline 32 and the filling sleeves 11 are removed from the pre-embedded sleeve 2, and a new pipeline 32 can be reinstalled according to the above method. This device can effectively block radiation, facilitate the replacement of the pipeline 32, improve the efficiency of secondary wiring, and benefit subsequent maintenance work.

[0046] The inner side of the pre-embedded sleeve 2 and the outer side of the filling sleeve 11 are both coated with an anti-radiation coating. By setting the anti-radiation coating, the radiation rays entering between the pre-embedded sleeve 2 and the filling sleeve 11 can be absorbed, thereby further improving the anti-radiation effect of the device.

[0047] The radiation shielding material inside the filling sleeve 11 is radiation shielding rubber 12. Compared with other radiation shielding materials, such as high-density mortar, radiation shielding rubber 12 is lightweight, easy to install, and has strong insulation capabilities, making it more suitable for the prefabrication construction of this device. By prefabricating and installing the radiation shielding rubber 12 inside the filling sleeve 11 in advance, in actual operation, it is only necessary to insert the filling sleeve 11 into the pre-embedded sleeve 2, without the need to fill radiation shielding material on site, further simplifying the construction process.

[0048] The fixing assembly includes a connecting groove 13 formed inside the pre-embedded sleeve 2, and the connecting groove 13 is annular; a groove 14 is formed at the end of the filling sleeve 11; a set of through grooves are evenly distributed between the groove 14 and the outer side of the filling sleeve 11; a retaining strip 15 is slidably connected inside the through groove; one end of the retaining strip 15 protruding from the surface of the filling sleeve 11 is provided with an inclined surface; one end of the retaining strip 15 extending into the groove 14 is fixedly connected to a pressure plate 16; a spring 17 is fixedly connected between the pressure plate 16 and the side wall of the groove 14; during the process of inserting the filling sleeve 11 into the pre-embedded sleeve 2, the pre-embedded sleeve 2 squeezes the inclined surfaces of multiple retaining strips 15, squeezing the retaining strips 15 into the through groove, and stretching the spring 17. When the through groove is aligned with the connecting groove 13, under the action of the spring 17, the ends of multiple retaining strips 15 are inserted into the connecting groove 13, realizing the fixed installation between the filling sleeve 11 and the pre-embedded sleeve 2, and the fixing process is convenient and quick.

[0049] A movable ring 18 is slidably connected inside the groove 14; a second spring 19 is fixedly connected between the movable ring 18 and the end of the groove 14; a connecting plate 20 is fixedly connected to the side of the pressure plate 16 away from the clamping strip 15; a guide groove 21 is opened on the surface of the connecting plate 20; a set of inclined guide blocks 22 are evenly distributed on the side of the movable ring 18 near the second spring 19; the inclined guide blocks 22 correspond one-to-one with the connecting plate 20 and pass through the inside of the guide groove 21; when the pipeline 32 needs to be replaced, the movable ring 18 is pulled outward, and then multiple inclined guide blocks 22 slide inside the guide groove 21, using the inclined surface of the inclined guide blocks 22 to press the connecting plate 20, and drive multiple clamping strips 15 to slide and converge towards the middle, and then the clamping strips 15 disengage from the joint groove 13, realizing the release and fixation between the filling sleeve 11 and the pre-embedded sleeve 2, and then the filling sleeve 11 can be taken out.

[0050] An annular groove 31 is provided on the outer side of the filling sleeve 11; a water-stop ring 23 is provided inside the annular groove 31, and the water-stop ring 23 is made of a water-swellable material; by setting the water-stop ring 23 between the filling sleeve 11 and the pre-embedded sleeve 2, the water-stop ring 23 expands when it comes into contact with water, preventing water from leaking through the gap between the two and improving the water-proof effect of the radiation-proof concrete.

[0051] Example 2: Figures 8 to 10As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a stop block 24 is fixedly connected inside the pre-embedded sleeve 2 near the end of the filling sleeve 11; a pressure ring 25 is provided at the end of the filling sleeve 11; a hollow elastic ring 26 is fixedly connected between the filling sleeve 11 and the pressure ring 25, and the elastic ring 26 is corrugated; a set of air grooves 27 are evenly distributed inside the radiation-proof rubber 12; the air grooves 27 and the elastic ring 26 are interconnected through an air pipe 28; in the design, the diameter of the through hole inside the radiation-proof rubber 12 can be appropriately increased to facilitate the installation of pipelines. The 32 line passes smoothly through the radiation-shielding rubber 12, reducing the difficulty of threading. During the process of inserting the filling sleeve 11 into the pre-embedded sleeve 2, the stop block 24 squeezes the elastic ring 26 through the pressure ring 25, forcing the air inside the elastic ring 26 into the multiple air grooves 27 through the air pipe 28, causing the air grooves 27 to expand. The expansion of the air grooves 27 causes the radiation-shielding rubber 12 to clamp the pipeline 32. On the one hand, it can fix the pipeline 32, and on the other hand, it can reduce the gap between the radiation-shielding rubber 12 and the pipeline 32, preventing radiation rays from passing through this gap, and further improving the radiation protection effect of this device.

[0052] A set of guide tubes 29 are evenly distributed at the end of the filling sleeve 11; a guide rod 30 is slidably connected inside the guide tube 29, and one end of the guide rod 30 extending outside the guide tube 29 is fixedly connected to the pressure ring 25; by setting multiple guide tubes 29 and guide rods 30 to slide and cooperate, the movement process of the pressure ring 25 can be limited, so that when the stop block 24 squeezes the pressure ring 25, the pressure ring 25 always remains parallel to the end of the filling sleeve 11, thereby improving the squeezing efficiency of the pressure ring 25 on the elastic ring 26.

[0053] like Figure 11 As shown, a construction method for a radiation-proof computer room, which uses the aforementioned construction device for a radiation-proof computer room, includes the following steps:

[0054] S1: Tie the wall panels and roof slab reinforcement, and arrange cooling pipes in the wall panel reinforcement and roof slab reinforcement. Use steel pipe coupler scaffolding to erect the internal frame according to the shape and internal space size of the computer room.

[0055] S2: Wall panel and roof panel formwork 1 assembly, installation of embedded sleeve 2, rebar connector 3, embedded screw rod 4, recyclable screw rod 5, recyclable bolt joint 6, waterstop plate 7, wooden support 8, fastener 9, nut 10;

[0056] S3: Pour the top slab concrete and barite concrete in the radiant area, finish the surface, circulate water through the cooling pipes, and cure.

[0057] S4: Remove template 1, recyclable screw 5, recyclable bolt joint 6, wooden support 8, fastener 9, nut 10;

[0058] S5: Pass the pipeline 32 through the inside of the pre-embedded sleeve 2, and pass both ends of the pipeline 32 through the filling sleeve 11 respectively, and then insert the filling sleeve 11 into both ends of the pre-embedded sleeve 2 respectively.

[0059] S6: The retaining strip 15 is squeezed into the through groove by the pre-embedded sleeve 2. When the through groove is aligned with the connecting groove 13, the spring 17 drives the retaining strip 15 to be inserted into the connecting groove 13, thereby achieving the fixed installation between the filling sleeve 11 and the pre-embedded sleeve 2.

[0060] The reinforcing bars are HRB400E steel bars with a diameter of 25 mm. Straight threaded sleeves are used for the connection of the reinforcing bars, and the exposed thread shall not exceed 2 threads.

[0061] The spacing between cooling pipes should not exceed 1.5m to ensure sufficient contact area between the water pipes and the concrete, allowing the water pipes to quickly absorb and dissipate the heat inside the concrete.

[0062] For large-volume concrete, the cement, coarse and fine aggregates, admixtures, additives, and water should be properly mixed, and the amount of mixing water should not exceed 175 kg / m³. 3 The amount of fly ash should not exceed 40% of the cementitious material content, and the amount of slag powder should not exceed 50% of the cementitious material content. The total amount of fly ash and slag powder admixtures should not exceed 50% of the cementitious material content in the concrete. The water-cement ratio should not exceed 0.50, the sand ratio should be 38-42%, and the bleeding water content of the mixture should be less than 10 L / m³. 3 .

[0063] The strength grade of the radiation-shielding barite concrete is C30, and the pouring volume is 60 cubic meters. A separate production line needs to be set up before pouring. Before pouring, steel wire mesh and steel bars are used to intercept the ordinary concrete at the same location. The concrete is poured at the same time.

[0064] The overall concrete structure should be dense and clean, with a flat surface, neat and smooth edges and corners, and straight and clear beam-column joints, wall panel intersections, lines and surfaces. The arch lines and surfaces should be smooth, without honeycomb, pitting, peeling, holes, misalignment, rotten roots, cracks, and construction joints should be tight, flat, and free of impurities, cold joints, and mortar layers.

[0065] Working principle: After the recyclable screw 5 is removed from the pre-embedded sleeve 2, the pipeline 32 is first passed through the pre-embedded sleeve 2, and both ends of the pipeline 32 are passed through a filling sleeve 11. Then, the two filling sleeves 11 are inserted into both ends of the pre-embedded sleeve 2. In subsequent use, the radiation-proof material inside the filling sleeves 11 will play a role in isolating radiation. When the pipeline 32 needs to be replaced, the pipeline 32 and the filling sleeves 11 are removed from the pre-embedded sleeve 2, and then the new pipeline 32 can be reinstalled according to the above method. This device can play an effective role in radiation protection, facilitates the replacement of the pipeline 32, improves the efficiency of secondary wiring, and is beneficial to later maintenance work.

[0066] During the process of inserting the filling sleeve 11 into the pre-embedded sleeve 2, the pre-embedded sleeve 2 squeezes the inclined surfaces of multiple retaining strips 15, squeezing the retaining strips 15 into the through groove and stretching the spring 17. When the through groove is aligned with the connecting groove 13, under the action of the spring 17, the ends of multiple retaining strips 15 are inserted into the connecting groove 13, realizing the fixed installation between the filling sleeve 11 and the pre-embedded sleeve 2. The fixing process is convenient and quick. When the pipeline 32 needs to be replaced, the movable ring 18 is pulled outward, and then multiple inclined guide blocks 22 slide inside the guide groove 21. The inclined surfaces of the inclined guide blocks 22 squeeze the connecting plate 20 and drive the multiple retaining strips 15 to slide and converge towards the middle. Then the retaining strips 15 are released from the connecting groove 13, realizing the release of the fixed connection between the filling sleeve 11 and the pre-embedded sleeve 2. Then the filling sleeve 11 can be taken out.

[0067] During the process of inserting the filling sleeve 11 into the pre-embedded sleeve 2, the stop block 24 squeezes the elastic ring 26 through the pressure ring 25, forcing the air inside the elastic ring 26 into the multiple air grooves 27 through the air pipe 28, causing the air grooves 27 to expand. The expansion of the air grooves 27 causes the radiation-shielding rubber 12 to clamp the pipeline 32. On the one hand, it can fix the pipeline 32, and on the other hand, it can reduce the gap between the radiation-shielding rubber 12 and the pipeline 32, preventing radiation rays from passing through this gap, and further improving the radiation protection effect of this device. By setting multiple conduits 29 and slidingly engaging with the guide rod 30, the movement of the pressure ring 25 can be limited, so that when the stop block 24 squeezes the pressure ring 25, the pressure ring 25 always remains parallel to the end of the filling sleeve 11, thereby improving the squeezing efficiency of the pressure ring 25 on the elastic ring 26.
