Description

Technical Field

[0001] This invention relates to the field of embedded component installation technology, and in particular to an embedded support platform suitable for heavy loads and high precision, and its embedded process. Background Technology

[0002] With my country's rapid economic development, large-scale scientific projects, large-scale scientific facilities, and large-scale infrastructure projects are increasing. Most of these projects are equipped with large equipment, which bears enormous loads during operation. Therefore, the installation of this large equipment requires the pre-embedded support platforms during civil construction to meet the load-bearing requirements. Moreover, the equipment in large-scale scientific projects and large-scale scientific facilities is often quite sophisticated, requiring high precision from the pre-embedded support platforms. This presents both new opportunities and challenges for the construction of large-scale pre-embedded support platforms.

[0003] In traditional installation processes, embedded support platforms are fixed by welding to the structural steel reinforcement, followed by concrete pouring. However, heavy-duty embedded support platforms bear significant loads, which are applied directly to the steel reinforcement before concrete is poured. This can cause deformation and misalignment of the reinforcement, leading to tilting or displacement of the embedded support platform. Furthermore, during construction, worker operations on the reinforcement surface, the placement of tools and equipment, and vibrations inevitably disturb the reinforcement, further contributing to tilting and misalignment. This makes it impossible to meet the precision requirements of high-precision equipment, ultimately hindering installation. Summary of the Invention

[0004] This invention provides a high-precision embedded support platform suitable for heavy loads and its embedded process, which can solve the technical problem in the prior art where the load is directly applied to the steel bars before the concrete is poured, causing deformation and displacement of the structural steel bars, which in turn leads to the deviation and tilting of the embedded support platform.

[0005] A high-precision embedded support platform suitable for heavy loads includes a support ring plate, an L-shaped positioning ring, and several T-shaped positioning rings. The support ring plate, the L-shaped positioning ring, and the several T-shaped positioning rings are connected to several anchor bolts through a fixing mechanism. Several diagonal braces are also fixed outside the T-shaped positioning rings, and horizontal braces are fixed inside the L-shaped positioning rings and the T-shaped positioning rings.

[0006] The anchor bolt is provided with external threads corresponding to the positions of the support ring plate, the L-shaped positioning ring and the T-shaped positioning ring;

[0007] The fixing mechanism includes a ring and a detachable nut for threaded connection of external threads. The detachable nut includes two half nuts that are detachably connected. The half nuts include a half hexagonal nut and a semi-cylindrical nut that is fixedly connected to the half hexagonal nut.

[0008] At least one side of the support ring plate and / or the L-shaped positioning ring and / or the T-shaped positioning ring is provided with a ring around the anchor bolt, and the inner diameter of the ring is adapted to the outer diameter of the semi-cylindrical nut.

[0009] Furthermore, the end of the external thread is located inside the corresponding ring.

[0010] Furthermore, the two half nuts are engaged with each other, and the detachable connection of the two half nuts is provided with a groove and a block, which engage with each other.

[0011] And / or magnetic attraction, the detachable connection of the two half nuts is provided with a slot and a block respectively, the slot and the block engage with each other, and there are magnets that attract each other in the slot and the block respectively.

[0012] Furthermore, there are two T-shaped positioning rings, which are located between the support ring plate and the L-shaped positioning ring.

[0013] Furthermore, the cross brace includes cross brace A and several cross braces B. The anchor bolt is provided with external thread at the connection between it and the L-shaped positioning ring, the T-shaped positioning ring and the support ring plate. The diagonal brace includes several diagonal braces A in a circular array and several diagonal braces B in a circular array. A fixed support is provided on the outside of the anchor bolt. The T-shaped positioning ring is fixedly connected to the fixed support through the diagonal brace.

[0014] Furthermore, the support ring plate is provided with anchor bolt positioning holes and lifting ear plates, a number of shear keys are provided below the support ring plate, a number of guide plates are provided on the side of the support ring plate, a number of grouting holes are provided on the support ring plate, and a number of reserved bolt holes for installation are also provided on the support ring plate, with temporary bolts provided in the reserved bolt holes.

[0015] Furthermore, the bottom of the L-shaped positioning ring is provided with several anchor bolt end plates.

[0016] An embedded process suitable for heavy-load, high-precision embedded support platforms includes the following steps:

[0017] Step 1: First, tie the bottom reinforcing bars and pour the concrete;

[0018] Step 2: Construct the pre-embedded support platform. First, install the L-shaped positioning ring. The L-shaped positioning ring is fixed to the pouring surface by four anchor bolts. The L-shaped positioning ring and the anchor bolts are fixed by a fixing mechanism. Then, install the middle T-shaped positioning ring and weld the diagonal brace between the middle T-shaped positioning ring and the pouring surface. Next, install the upper T-shaped positioning ring and weld the diagonal brace between the upper T-shaped positioning ring and the pouring surface. Finally, install all the remaining anchor bolts on the L-shaped positioning ring, the middle T-shaped positioning ring, and the upper T-shaped positioning ring.

[0019] Step 3: Install the steel reinforcement bracket and tie the steel reinforcement before pouring concrete. Except for the top, the entire pre-embedded support platform is embedded in the concrete. A grouting groove is left at the top of the pre-embedded support platform. After tying the steel reinforcement to the grouting groove, the support ring plate is installed on the anchor bolts at the top of the pre-embedded support platform. After installation, concrete is poured again to complete the pre-embedding of the pre-embedded support platform.

[0020] Beneficial effects

[0021] 1. The present invention provides a pre-embedded support platform suitable for heavy loads and high precision. The support ring plate is fixedly connected to two lower T-shaped positioning rings and one L-shaped positioning ring with nuts using anchor bolts to form an independent structure. The T-shaped positioning rings and L-shaped positioning rings are welded to an internal through cross brace A and six cross braces B to ensure rigidity. The middle T-shaped positioning ring is fixed to the inner ring fixed support by welding with the diagonal brace A, and the upper T-shaped positioning ring is fixed to the outer ring fixed support by welding with the diagonal brace B. The fixed support is pre-embedded in the lower stable structure to ensure the overall stability.

[0022] 2. The embedded support platform is not connected to the structural steel reinforcement and is an independent and stable support system. This avoids the problems of embedded deviation and tilting caused by the large load on the embedded support platform, steel reinforcement disturbance, and construction vibration during the embedded process, and effectively ensures the embedded accuracy of the high-precision embedded support platform under heavy load.

[0023] 3. With the detachable nut, when fixing the T-shaped positioning ring and anchor bolt on the pre-embedded support platform, the fixing mechanism does not need to be inserted from above and slid into the installation position. Simply engage the two half nuts and tighten them to fix the T-shaped positioning ring. The operation is simple, does not require repeated movement, and can save a lot of time.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the 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.

[0042] Example 1

[0043] like Figures 1 to 9 As shown in Embodiment 1 of the present invention, a pre-embedded support platform suitable for high precision under heavy loads and its pre-embedding process are provided. In traditional pre-embedded support platform installation, the platform is fixed by welding to the structural reinforcing bars, followed by concrete pouring. However, the pre-embedded support platform itself bears a particularly large load, which is directly applied to the reinforcing bars before concrete pouring. This causes deformation and misalignment of the structural reinforcing bars, resulting in the pre-embedded support platform tilting. Furthermore, during structural construction, workers operating on the reinforcing bars, stacking tools and equipment, and vibrations inevitably disturb the reinforcing bars, further contributing to the tilting of the pre-embedded support platform. This fails to meet the precision requirements of high-precision equipment, leading to installation problems. Therefore, this embodiment proposes a pre-embedded support platform to improve upon these issues.

[0044] Specifically, it includes a support ring plate 1, an L-shaped positioning ring 21, and a T-shaped positioning ring 22. The support ring plate 1, the L-shaped positioning ring 21, and the T-shaped positioning ring 22 are fixed together by several anchor bolts 2. The T-shaped positioning ring 22 is located between the support ring plate 1 and the L-shaped positioning ring 21. Several diagonal braces are also fixed outside the T-shaped positioning ring 22. Horizontal braces are fixed inside both the L-shaped positioning ring 21 and the T-shaped positioning ring 22. The horizontal braces include horizontal brace A212 and several horizontal braces B213. The length of horizontal brace A212 is greater than the length of horizontal brace B213. The length of horizontal brace A212 is about twice the length of horizontal brace B213.

[0045] In this embodiment, the embedded support platform is not connected to the structural steel reinforcement and is an independent and stable support system. The construction of the embedded support platform is carried out alternately with the construction of the structural steel reinforcement, ensuring that the structural steel reinforcement passes through the inside of the embedded support platform but does not contact the support platform. This avoids the problems of embedded deviation and tilting caused by the large load of the embedded support platform, steel reinforcement disturbance, and construction vibration during the embedded process, effectively ensuring the embedded accuracy of the high-precision embedded support platform under heavy load.

[0046] Furthermore, such as Figure 2 and 3As shown, in this embodiment, the number of anchor bolts 2 is sixteen and the number of T-shaped positioning rings 22 is two. However, in this technical solution, the number of anchor bolts 2 can be any greater than four, and the number of T-shaped positioning rings 22 can be any greater than two. Specifically, the support ring plate 1 is connected to one L-shaped positioning ring 21 and two T-shaped positioning rings 22 by sixteen anchor bolts 2 to form a whole. The anchor bolts 2 are provided with external threads 23 at the connection points with the L-shaped positioning rings 21, T-shaped positioning rings 22 and support ring plate 1. The diameter of the external threads 23 is larger than the diameter of the anchor bolts 2. The anchor bolts 2 are fixed to the L-shaped positioning rings 21, T-shaped positioning rings 22 and support ring plate 1 by fixing mechanisms. In this embodiment, the fixing mechanism is specifically connected and fixed by leveling nuts 24, leveling washers 25 and fastening nuts 26 and fastening washers 27. The leveling nuts 24 and fastening nuts 26 are conventional nuts. By rotating the leveling nut 24, the support height of the L-shaped positioning ring 21, T-shaped positioning ring 22, or support ring plate 1 can be changed, thereby achieving height and level adjustment of the L-shaped positioning ring 21, T-shaped positioning ring 22, or support ring plate 1; by tightening the fastening nut 26, the L-shaped positioning ring 21, T-shaped positioning ring 22, or support ring plate 1 can be fixed.

[0047] In this embodiment, the two T-shaped positioning rings 22 are respectively set in the middle and upper part of the anchor bolt 2. The L-shaped positioning ring 21 and the two T-shaped positioning rings 22 are each fixedly provided with a through cross brace A212, six cross braces B213 and a connecting plate 214. The cross braces A212, cross braces B213 and connecting plate 214 are also fixedly connected. The above-mentioned fixed connection method is preferably welding, and the rigidity is ensured by welding.

[0048] In this embodiment, the diagonal bracing includes several circumferentially arranged diagonal bracings A215 and several circumferentially arranged diagonal bracings B216. The outer side of the T-shaped positioning ring 22 located in the middle of the anchor bolt 2 is fixed to the fixed support 211 through the diagonal bracing A215, and the upper T-shaped positioning ring 22 is fixed to the fixed support 211 through the diagonal bracing B216, making the entire pre-embedded support platform an independent and stable structural system. In this embodiment, the fixing method of the two ends of the diagonal bracing A215 and diagonal bracing B216 is preferably welding.

[0049] like Figures 4 to 5 As shown, in this embodiment, the L-shaped positioning ring 21 is located at the bottom of the pre-embedded support platform. The L-shaped positioning ring 21 has sixteen anchor bolt positioning holes 28 corresponding to the anchor bolts 2. Specifically, the L-shaped positioning ring 21 contains one through-bracing A212, six cross braces B213, and a connecting plate 214. The connecting plate 214 is located at the center of the L-shaped positioning ring 21. Both ends of the cross brace A212 are fixed inside the L-shaped positioning ring 21, and the middle of the cross brace A212 is fixedly connected to the connecting plate 214. Both ends of the cross brace B213 are fixedly connected to the connecting plate 214 and the L-shaped positioning ring 21, respectively.

[0050] Specifically, sixteen anchor bolt end plates 29 are provided below the L-shaped positioning ring 21, such as... Figure 9 As shown, each anchor bolt end plate 29 has an anchor bolt hole 210. The anchor bolt 2 is fixedly connected to the anchor bolt hole 210 on the anchor bolt end plate 29 through the anchor bolt positioning hole 28 on the L-shaped positioning ring 21. The anchor bolt end plate 29 is leveled by the two leveling nuts 24 and the leveling shims 25 below. The L-shaped positioning ring 21 is connected and fixed to the anchor bolt 2 by the fastening nut 26 and the fastening shims 27 above, so that the anchor bolt 2 and the L-shaped positioning ring 21 are connected as a whole.

[0051] like Figures 6 to 7 As shown, in this example, the T-shaped positioning ring 22 also has sixteen anchor bolt positioning holes 28 corresponding to the anchor bolts 2. The T-shaped positioning ring 22 is equipped with a through cross brace A212, six cross braces B213 and a connecting plate 214. The arrangement and fixing method of the cross braces A212, cross braces B213 and connecting plate 214 in the T-shaped positioning ring 22 are the same as those on the L-shaped positioning ring 21. Welding is preferred as the fixing method. Welding ensures rigidity. Both T-shaped positioning rings 22 are leveled by the lower leveling nut 24 and leveling washer 25. Both T-shaped positioning rings 22 are connected and fixed to the anchor bolts 2 by the upper fastening nut 26 and fastening washer 27.

[0052] Specifically, in this embodiment, there are eight diagonal braces A215 and B216. The outer side of the anchor bolt 2 is uniformly and circumferentially arrayed with two rings of fixing supports 211, with eight fixed supports arranged on each ring. The fixing supports 211 are pre-embedded in the stable structure below. The outer side of the T-shaped positioning ring 22 in the middle of the anchor bolt 2 is connected to the inner ring of fixing supports 211 through the diagonal brace A215 to form a stable support structure. The outer side of the T-shaped positioning ring 22 in the upper part of the anchor bolt 2 is connected to the outer ring of fixing supports 211 through the diagonal brace B216 to form a stable support structure.

[0053] like Figure 8 As shown, in this example, the support ring plate 1 has sixteen anchor bolt positioning holes 28 corresponding to the anchor bolts 2 for positioning. Four lifting lugs 11 are evenly arranged on the top of the support ring plate 1 for lifting the support ring plate 1. Shear keys 16 are evenly arranged on the bottom of the support ring plate 1. The shear keys 16 are fixed to the bottom of the support ring plate 1 by welding. Shear force is transmitted through the lateral bearing pressure between the vertical side of the shear key 16 and the concrete foundation. When the lateral force is applied, the force is directly transmitted through the side of the shear key 16, ensuring that the equipment will not slide relative to the foundation under operation, earthquake or accidental impact, and avoiding reliance on the anchor bolts 2 to bear the horizontal force.

[0054] like Figure 1 and Figure 9As shown, four guide plates 12 are arranged in a circumferential array on the side of the support ring plate 1. The guide plates 12 are used for directional control of the support ring plate 1. The support ring plate 1 is positioned according to the directional control of the guide plates 12. Eight grouting holes 13 are opened on the support ring plate 1. The grouting holes 13 are used for later structural construction. The support ring plate 1 is also provided with reserved bolt holes 14 for installation. The reserved bolt holes 14 are sealed with temporary bolts 15 before structural construction to avoid damage to the reserved bolt holes 14 during structural construction. The function of the grouting holes 13: In this embodiment, the support ring plate 1 is installed last. After the support ring plate 1 is installed, it needs to be grouted. If the grout is directly injected from its edge, the grout will not be evenly filled into all the gaps below the support ring plate 1. Therefore, we provide grouting holes 13 to ensure that the gaps below the support ring plate 1 are completely filled. The grout is injected from the grouting holes 13 by a grouting pump, and the grouting pressure makes the grout fill all the gaps below the support ring plate 1. The purpose of the reserved bolt hole 14 is to allow the equipment to be connected to the upper equipment via high-strength bolts through the reserved bolt hole 14. When the upper equipment is installed, the temporary bolt 15 is removed before the equipment is installed.

[0055] Specifically, the support ring plate 1 is set on top of the anchor bolt 2. The support ring plate 1 is fixedly connected to the anchor bolt 2 below by two leveling nuts 24 and anchor bolt pads 217 to adjust the elevation and flatness of the support ring plate 1. The support ring plate 1 is fixedly connected to the anchor bolt 2 above by two fastening nuts 26 and anchor bolt pads 217 to ensure the stability of the support ring plate 1.

[0056] Example 2

[0057] During the construction of the pre-embedded support platform of the present invention, the L-shaped positioning ring 21, T-shaped positioning ring 22 and anchor bolt 2 need to be fixed by a fixing mechanism. The construction process is carried out from the bottom in advance. That is, the fixing between the L-shaped positioning ring 21 and the anchor bolt 2 can be achieved by first installing the leveling nut 24 and the leveling washer 25 in the designated position, then inserting the anchor bolt 2 onto the anchor bolt end plate 29 and the L-shaped positioning ring 21, and finally fixing it with the fastening nut 26 and the fastening washer 27 to complete the fixing of the bottom L-shaped positioning ring 21. However, when it is necessary to fix the T-shaped positioning ring 22 and the anchor bolt 2, the fastening nut 26 and the leveling nut 24 need to be put on from the top of the anchor bolt 2 to fix the T-shaped positioning ring 22 and the anchor bolt 2. Since the anchor bolt 2 is relatively high, it is necessary for the workers to leave the installation position or for a special person to put it on from the top, which is a relatively cumbersome and inconvenient operation.

[0058] To address the problem of difficulty in fitting the fastening nut 26 and leveling nut 24 during the installation of the T-shaped positioning ring 22, this embodiment provides a solution to resolve the aforementioned issue.

[0059] like Figure 10As shown, the fixing mechanism for the upper and lower ends of the T-shaped positioning ring 22 in this embodiment adopts a detachable design, specifically including a ring 31 and a detachable nut 3 fixedly installed on the upper and lower ends of the T-shaped positioning ring 22. The anchor bolt 2 passes through the T-shaped positioning ring 22 and its upper and lower end rings 31, and then the detachable nut 3 is installed in the ring 31 to fix the T-shaped positioning ring 22 on the anchor bolt 2.

[0060] like Figure 11 , Figure 12 , Figure 13 As shown, the detachable nut 3 includes two half nuts that are detachably connected. Each half nut includes a hexagonal nut 33 and a cylindrical nut 32. The hexagonal nut 33 is fixedly mounted on the top of the cylindrical nut 32. Both half nuts have a semi-thread 34 inside. When the two half nuts are spliced ​​together, they can form a complete thread. The detachable connection between the two half nuts includes magnetic attraction and snap-fit. Specifically, the snap-fit ​​method is that the detachable connection of the two half nuts is provided with a slot 36 and a block 35, respectively. When they are spliced ​​together, the slot 36 and the block 35 engage without gap. Specifically, the magnetic attraction method is that the detachable connection of the half nuts is provided with a slot 36 and a block 35. Magnets that attract each other are fixed in the slot 36 and the block 35, respectively. When the slot 36 and the block 35 engage, they are further attracted and fixed.

[0061] The inner diameter of the ring 31 is adapted to the outer diameter of the semi-cylindrical nut 32.

[0062] In use, two half nuts are attached to the cylindrical rod of anchor bolt 2 and then spliced ​​together by the slot 36 and the block 35 or by magnetic attraction to form a complete detachable nut 3. Then, the detachable nut 3 is pushed downwards to make the semi-thread 34 on the detachable nut 3 contact the external thread 23, and the detachable nut 3 is rotated to make the semi-thread 34 and the external thread 23 threadedly engage. At this time, the detachable nut 3 will gradually move into the ring 31 until the semi-cylindrical nut 32 moves to the bottom of the ring 31 and contacts the surface of the T-shaped positioning ring 22, fixing the T-shaped positioning ring 22. The height of the semi-cylindrical nut 32 and the ring 31 are the same. When the semi-cylindrical nut 32 moves to the bottom, the semi-hexagonal nut 33 is attached to the top of the ring 31, and the semi-cylindrical nut 32 and the ring 31 are fitted together without gap.

[0063] like Figure 14 As shown, if the two half-nuts, after being spliced ​​together, directly engage with the external thread 23, during tightening, if the two half-nuts are not tightly fitted, a certain gap or rotational movement angle will occur between the half-thread 34 and the external thread 23. Figure 15 As shown, this ultimately leads to a situation where they cannot fit together. Therefore, we solve the above problem by providing a ring 31, as follows: Figure 14As shown, the external threads 23 on the anchor bolt 2, located at the upper and lower ends of the T-shaped positioning ring 22, are both inside the ring 31, and the height of the external threads 23 is lower than the height of the ring 31. In use, the two half nuts are first spliced ​​together. At this time, the spliced ​​detachable nut 3 is located on the unthreaded part of the anchor bolt 2. Then, the detachable nut 3 is moved towards the direction with external threads 23. Since the inner diameter of the ring 31 is compatible with the outer diameter of the semi-cylindrical nut 32, the detachable nut 3 is inserted into the ring 31 without gap. When it is first inserted into the ring 31, the half thread 34 and the external thread 23 are not in contact. As it is further inserted, the detachable nut 3 and the external thread 23 begin to cooperate. At this time, the ring 31 will limit the two half nuts, that is, ensure that when the half thread 34 and the external thread 23 begin to cooperate, the two half nuts will not move or form an angle, ensuring that the half thread 34 and the external thread 23 can be fully cooperated.

[0064] An embedded process suitable for heavy-load, high-precision embedded support platforms includes the following steps:

[0065] Step 1: First, pour the bottom layer of concrete, then tie the bottom reinforcement of the base slab and install the embedded parts, including the embedding of the inner and outer rings of fixed supports 211. Then, insert the structural reinforcement bars and pour the second layer of concrete.

[0066] Step 2: Construction of the second base plate, including the construction of the pre-embedded support platform. First, install the L-shaped positioning ring 21. Anchor bolt end plates 29 are installed at the bottom of the L-shaped positioning ring 21. Then, install four anchor bolts 2. The anchor bolt end plates 29 are used to level the L-shaped positioning ring 21 through the two leveling nuts 24 and leveling washers 25 below. The L-shaped positioning ring 21 is connected and fixed to the anchor bolts 2 through the upper fastening nuts 26 and fastening washers 27, so that the anchor bolts 2 and the L-shaped positioning ring 21 are connected as a whole. Then, install the middle T-shaped positioning ring 22 and weld the diagonal brace A215 to the middle T-shaped positioning ring 22 and the inner ring fixed support 211. Next, install the upper T-shaped positioning ring 22 and weld the diagonal brace B216 to the upper T-shaped positioning ring 22 and the outer ring fixed support 211. Then, install all the remaining anchor bolts 2 in the corresponding positions.

[0067] Step 3: Install the steel reinforcement support and tie the steel bars. Use No. 10 channel steel as the column, No. 8 channel steel as the main beam, 60 angle steel as the secondary beam, and 30 angle steel as the diagonal tie. Install the reinforcing bars and embedded parts at the constraint edges, and pour the third layer of concrete. After pouring, build the steel reinforcement and then pour the fourth layer of concrete. At this time, the embedded support platform is embedded in the concrete except for the top. At this time, the top of the embedded support platform has a grouting groove. After tying the steel bars in the grouting groove, install the support ring plate 1 on the anchor bolt 2 at the top of the embedded support platform. After installation, pour concrete again to complete the embedding of the embedded support platform.

A pre-embedded support platform suitable for heavy loads and high precision, characterized in that, It includes a support ring plate (1), an L-shaped positioning ring (21) and several T-shaped positioning rings (22). The support ring plate (1), the L-shaped positioning ring (21) and the several T-shaped positioning rings (22) are connected to several anchor bolts (2) through a fixing mechanism. Several diagonal braces are also fixed on the outside of the T-shaped positioning rings (22). Horizontal braces are fixed inside the L-shaped positioning rings (21) and the T-shaped positioning rings (22). The anchor bolts (2) are provided with external threads (23) corresponding to the positions of the support ring plate (1), the L-shaped positioning rings (21) and the T-shaped positioning rings (22). The fixing mechanism includes a ring (31) and a detachable nut (3) for threaded connection of external thread (23). The detachable nut (3) includes two half nuts that are detachably connected. The half nuts include a half hexagonal nut (33) and a semi-cylindrical nut (32) that is fixedly connected to the half hexagonal nut (33). At least one side of the support ring plate (1) and / or the L-shaped positioning ring (21) and / or the T-shaped positioning ring (22) is provided with a ring (31) around the anchor bolt (2), and the inner diameter of the ring (31) is adapted to the outer diameter of the semi-cylindrical nut (32). Both half-nuts have a semi-thread (34) inside. The two half-nuts can be spliced ​​together to form a complete thread. The two half-nuts can be detachably connected by magnetic attraction and snap-fit. The circular ring (31) is fixedly installed at the upper and lower ends of the T-shaped positioning ring (22). The external threads (23) on the anchor bolt (2) located at the upper and lower ends of the T-shaped positioning ring (22) are both located inside the circular ring (31), and the height of the external threads (23) is lower than the height of the circular ring (31). The semi-cylindrical nut (32) has the same height as the ring (31). When in use, take two half nuts and fit them against the cylindrical rod part of the anchor bolt (2). After being snapped or magnetically attracted by the slot (36) and the block (35), the two half nuts are spliced ​​together to form a complete detachable nut (3). At this time, the detachable nut (3) after splicing is located on the unthreaded part of the anchor bolt (2). Then push the detachable nut (3) downward. Since the inner diameter of the ring (31) is compatible with the outer diameter of the semi-cylindrical nut (32), the detachable nut (3) is inserted into the ring (31) without gap. When it is first inserted into the ring (31), the semi-thread (34) and the external thread (23) are not in contact. As it is further inserted, the detachable nut (3) and the external thread (23) begin to cooperate. At this time, the ring (31) will limit the two half nuts to ensure that when the semi-thread (34) and the external thread (23) begin to cooperate, the two half nuts will not move or form an angle, ensuring that the semi-thread (34) and the external thread (23) can be fully cooperated. Then rotate the entire detachable nut (3), and the detachable nut (3) will gradually move into the ring (31) until the semi-cylindrical nut (32) moves to the bottom of the ring (31) and contacts the surface of the T-shaped positioning ring (22). The height of the semi-cylindrical nut (32) and the ring (31) are the same. When the semi-cylindrical nut (32) moves to the bottom, the semi-hexagonal nut (33) fits against the top of the ring (31), and the semi-cylindrical nut (32) and the ring (31) fit together without gap, thus fixing the T-shaped positioning ring (22).
