Description

Technical Field

[0001] This invention relates to the field of wall expansion joint technology, and in particular to a radiation-proof wall joint structure. Background Technology

[0002] The ultra-short, ultra-intense laser platform is a large-scale scientific facility and application development platform based on laser wake acceleration technology, enabling the output of ultrafast synchrotron radiation X-ray sources, high-quality electron beams, proton beams, etc. During the construction of the ultra-short, ultra-intense laser platform, radiation shielding treatment of the walls is required. Simultaneously, the concrete walls require high thickness and long length, constituting large-volume concrete components. Expansion joints are reserved to release the volumetric deformation stress caused by temperature changes in the concrete and to prevent the risk of wall cracking due to factors such as geological settlement. Current radiation shielding wall joint structures typically use tongue-and-groove joints to accommodate wall cracking. However, traditional tongue-and-groove joints are not conducive to bidirectional expansion and contraction, and are usually only used to accommodate crack expansion. Traditional joint structures also make it difficult to regularly monitor wall settlement and expansion / contraction. When wall settlement or joint expansion / contraction is excessive, it is difficult for workers to detect, and excessive joint deformation can still easily lead to wall cracking. Furthermore, during the casting process, traditional tongue-and-groove joint structures are prone to initial positional deviations due to factors such as formwork clamping, making it difficult to adjust the joint structure after the concrete has cured.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figures 1 to 10 :

[0035] This invention proposes a radiation-proof wall joint structure, including a radiation-proof wall section 1, on which a first joint member 2 is installed; a second joint member 3 is installed on the radiation-proof wall section 1; the first joint member 2 is inserted into the second joint member 3; a joint detection member 4 is installed on the second joint member 3; an elastic joint member 5 connects the first joint member 2 and the second joint member 3; a casting positioning member 6 is installed on the second joint member 3; the radiation-proof wall section 1 includes: a cast wall 101 and a lead plate 102, the cast wall 101 is cast and formed; a reinforcing cage is provided inside the cast wall 101; there are two cast walls 101, and lead plates 102 are respectively pasted on the two cast walls 101.

[0036] In this embodiment, the first joint component 2 includes: a joint lead block 201, an inner lead block 2011, an inner steel shell 202, a first connecting rib 2021, a lead insert 2022, and an inner support spring 203. Two inner lead blocks 2011 are fixedly installed on the joint lead block 201. An inner steel shell 202 is fixedly installed on the side of the joint lead block 201, and a row of first connecting ribs 2021 is welded on the inner steel shell 202. The row of first connecting ribs 2021 is used to connect to the reinforcing cage in the right-side cast wall 101. The row of first connecting ribs 2021 passes through the joint lead block 201. A lead insert 2022 is fixedly installed on the inner steel shell 202. 022; The inner steel shell 202 and the right-side cast wall 101 are cast and formed; Two rows of inner support springs 203 are fixedly installed inside the inner steel shell 202, and the two rows of inner support springs 203 are used to elastically support the two inner lead blocks 2011 respectively; The second joint component 3 includes: an outer steel shell 301 and a second connecting rib 3011, a row of second connecting ribs 3011 is welded on the outer steel shell 301, and the row of second connecting ribs 3011 is used to connect to the reinforcing cage inside the left-side cast wall 101; The outer steel shell 301 and the left-side cast wall 101 are cast and formed; Two lead plates 102 are respectively pasted on the outer steel shell 301 and the joint lead block 201. The second joint component 3 further includes: a sleeve lead block 302 and a fitting lead block 303. The sleeve lead block 302 is fixedly installed inside the outer steel shell 301; the outer sides of two inner lead blocks 2011 are respectively fitted to the inner sides of the sleeve lead block 302; two fitting lead blocks 303 are fixedly installed inside the sleeve lead block 302; the two fitting lead blocks 303 are respectively slidably inserted into the inner side of the inner steel shell 202; a lead insert 2022 is slidably fitted between the two fitting lead blocks 303. The use of the first joint component 2 in conjunction with the second joint component 3 facilitates the maintenance of the expansion joint adaptability of the radiation shielding wall 1, and avoids cracks in the radiation shielding wall 1 due to geological settlement and other factors. The first joint piece 2, in conjunction with the second joint piece 3, can adaptively expand and contract, accommodating the shrinkage and expansion of the cast-in-place wall 101. Simultaneously, the plug-in connection method prevents radiation leakage. This structure can be directly cast integrally with the cast-in-place wall 101. When the two cast-in-place walls 101 shrink and deform, the inner steel shell 202 and the outer steel shell 301 can slide and expand. During this process, under the elastic support of the inner support spring 203, the inner steel shell 202 itself has a certain elasticity, ensuring that the inner lead block 2011 can elastically fit against both sides of the inner side of the sleeve lead block 302, guaranteeing that the sleeve lead block 302 and the inner lead block 2011 remain in contact during expansion and contraction.

[0037] In this embodiment, the first joint component 2 further includes: an insulating pad 204 and an insulating sheet 205. Two insulating pads 204 are fixedly embedded on the inner lead block 2011 near the lead plate 102, and insulating sheets 205 are fixedly embedded on the two insulating pads 204 respectively. The joint detection component 4 includes: a sliding shaft seat 401 and a bonding post 402. Two sliding shaft seats 401 are fixedly installed on the lead block 302, and bonding posts 402 are slidably inserted into the two sliding shaft seats 401 respectively. The bonding post 402 is a plastic insulating structure. The joint detection component 4 further includes: an insulating post 403 and a tension spring 404. Two insulating posts 403 are fixedly inserted into the two bonding posts 402 respectively. The two terminals 403 are respectively attached to the terminals 205 on the same side; a tension spring 404 is sleeved on the terminal 402 and the tension spring 404 is connected between the terminal 403 and the sliding shaft seat 401; the elastic joint component 5 includes: a joint rubber strip 501 and a conductor 502. There are two joint rubber strips 501. The sides of the two joint rubber strips 501 are respectively attached to both sides of the outer steel shell 301; the other sides of the two joint rubber strips 501 are respectively attached to both sides of the joint lead block 201; two conductors 502 are respectively sleeved on the upper and lower sides of the joint rubber strip 501 near the lead plate 102, and the four conductors 502 are respectively welded to the four terminals 403. 3. The conductor 502 is equipped with an insulating sleeve on the outside; the joint rubber strip 501 can be connected between the outer steel shell 301 and the joint lead block 201 to ensure the aesthetics of the gap, improve the sealing quality of the joint, and prevent concrete leakage between the outer steel shell 301 and the joint lead block 201 during concrete pouring; the use of elastic joint component 5 in conjunction with joint detection component 4 facilitates the inspection work of the staff. Without disassembling the joint rubber strip 501, the degree of expansion and contraction between the first joint component 2 and the second joint component 3 can be quickly judged, avoiding the inconvenience of timely detection when the expansion and contraction exceeds the standard, and making it easier to understand the safety of the poured wall 101, because the two poured walls 101 are due to... When factors such as settlement cause excessive misalignment of the gap, there is still a risk of cracks forming inside the two cast-in-place walls 101. It is necessary to remove the lead plate 102 in time for inspection. The inspection of this structure is simple and flexible. If the sliding expansion and contraction adaptation range of the inner lead block 2011 inside the sleeve lead block 302 meets the standard, and the two electrical terminals 403 can simultaneously attach to the electrical contacts 205, the multimeter will show a circuit when manually tested. This makes it convenient for staff to regularly check the expansion gap of the two cast-in-place walls 101. The method of using two joint detection pieces 4 set at the top and bottom can ensure the accuracy of the test. The expansion joints on the upper and lower sides of the two cast-in-place walls 101 are tested separately.

[0038] In Example 2, based on Example 1, the casting positioning component 6 includes: sealing bolts 601, with a row of sealing bolts 601 threadedly connected to both sides of the outer steel shell 301; the casting positioning component 6 also includes: positioning shafts 602, with positioning shafts 602 threadedly connected to the two rows of sealing bolts 601, and the two rows of positioning shafts 602 respectively inserted into the inner steel shell 202; the two rows of positioning shafts 602 respectively pass through the sleeve lead block 302 and the inner lead block 2011; using the casting positioning component 6, the first joint component 2 and the second joint component 3 can be placed inside the template of the cast-in-place wall 101 for casting. During construction, the first joint piece 2 and the second joint piece 3 are positioned to ensure accurate initial positions. After the concrete has cured, the first joint piece 2 and the second joint piece 3 can expand and contract normally. At the same time, the positioning shaft 602 can be disassembled independently, and the outer steel shell 301 can be sealed separately with the sealing bolt 601. This prevents the adhesive or paint applied when installing the lead plate 102 or when painting the other side of the outer steel shell 301 from penetrating into the interior of the outer steel shell 301, thus ensuring that the first joint piece 2 and the second joint piece 3 can slide and expand normally.

[0039] The working principle of this embodiment is as follows: First, the first connecting bar 2021 and the second connecting bar 3011 are tied or welded to the steel cages inside the two cast-in-place walls 101 using steel wire. Then, the formwork can be closed normally, and the cast-in-place wall 101 is cast. After the cast-in-place wall 101 has solidified, the formwork is disassembled. Then, the two rows of sealing bolts 601 can be removed, and the positioning shaft 602 can be taken off. The inner positioning steel shell 202 and the outer steel shell 301 are no longer inserted. Then, the positioning shaft 602 can be removed by rotating it off the sealing bolts 601. Then, the two rows of sealing bolts 601 are tightened separately on the outer steel shell 301 using a hex wrench. Afterward, the backs of the two lead plates 102 can be coated with adhesive. The lead plates 102 are attached to the two cast-in-place walls 101, while maintaining the two lead plates 102 in contact with the outer steel shell 301 and the joint lead block 201 respectively. When the two cast-in-place walls 101 shrink and deform, the inner steel shell 202 and the outer steel shell 301 can slide and expand. During the process, under the elastic support of the inner support spring 203, the inner steel shell 202 itself has a certain elasticity, which can ensure that the inner lead block 2011 can elastically fit against the two sides inside the sleeve lead block 302. This ensures that the sleeve lead block 302 and the inner lead block 2011 remain in contact during the expansion and contraction process. At the same time, the lead insert 2022 can slide between the two attached lead blocks 303, ensuring the radiation protection quality and the stability of the joint during expansion and contraction.

[0040] Under the tension of the tension spring 404, the two contact posts 403 on the contact post 402 can be moved to the contact plate 205. When the inner lead block 2011 slides and extends inside the contact lead block 302, the contact posts 403 will also slide on the contact plate 205. Once the two contact posts 403 cannot be attached to the contact plate 205 at the same time, when either contact post 403 slides to the surface of the contact insulating pad 204, the two contact posts 403 cannot conduct electricity through the contact plate 205. During manual inspection, the two terminals of the multimeter are respectively attached to the two wires 502 above or below the joint rubber strip 501. If the circuit cannot form a continuity, it can visually indicate an abnormal expansion and contraction. Similarly, if the sliding expansion and contraction of the inner lead block 2011 inside the contact lead block 302 is within the standard range, the two contact posts 403 will not be able to conduct electricity. The electrical connector 205 can be attached simultaneously. When a multimeter is used to test the circuit, it will show a normal flow, indicating that the sliding and expansion between the inserted lead block 2011 and the sleeve lead block 302 is normal.
