For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Reference below Figure 1-Figure 8The installation method of the embedded structure according to the embodiment of the present invention is described, which can be used for the installation of embedded structures with special shapes, large sizes and heavy weights, and is easy to install and improve the strength of the embedded structure used to connect and support the controlled nuclear fusion device. The embedded installation structure is fixed with an upper and lower frame, an upper angle steel connecting frame 1, and a lower connecting plate 4. The connecting plate 4 can be a flat steel bar to improve the integrity and verticality of the multiple embedded ribs 2, thereby improving the overall strength of the embedded installation structure; and the horizontality of the connecting frame 1 and the embedded plate 5 can be adjusted to improve the horizontality and strength of the entire structure and make the force uniform; after the first pouring is completed, the angle steel connecting frame 1 can be cut to facilitate the subsequent installation of the embedded plate 5 and improve the installation accuracy of the embedded plate 5 and the multiple embedded ribs 2.

[0033] like Figure 1-8 As shown, a method for installing a pre-buried structure according to an embodiment of the present invention includes the following steps:

[0034] S1: Pass multiple embedded reinforcement bars 2 through and fix them to the connecting plate 4; in practice, the connecting plate 4 can be constructed in multiples, and each connecting plate 4 is provided with multiple connecting holes, and the multiple connecting holes of the multiple connecting plates 4 are connected to an embedded reinforcement bar 2 one by one, that is, the embedded reinforcement bar 2 passes through the connecting plate 4, and the connecting plate 4 is located between the two ends of the embedded reinforcement bar 2, such as the connecting plate 4 can be located around the middle position of the embedded reinforcement bar 2, and at the same time, at least part of the embedded reinforcement bars 2 of the multiple embedded reinforcement bars 2 are provided with a connecting end plate 23 at the bottom, and the connecting end plate 23 at the bottom of the embedded reinforcement bar 2 is connected to the supporting formwork of the building to maintain the connection stability between the embedded reinforcement bar 2 and the supporting formwork of the building, and each embedded reinforcement bar 2 is welded to the connecting plate 4 to form a frame body, maintaining the integrity of the multiple embedded reinforcement bars 2, thereby forming a frame of a large-sized embedded installation structure, that is, multiple embedded reinforcement bars 2 can be installed simultaneously through the connecting plate 4.

[0035] S2: vertically level the multiple embedded bars 2; specifically, since the embedded bars 2 are relatively long, after the multiple embedded bars 2 are installed on the connecting plate 4, some of the multiple embedded bars 2 may be tilted. By vertically leveling the multiple embedded bars 2, the verticality of the multiple embedded bars 2 is ensured, and a controllable embedded installation structure is finally formed, which is beneficial to subsequent installation operations. The strength of the formed embedded installation structure is reliable and the force is uniform.

[0036] Furthermore, when performing vertical leveling, a corresponding vertical leveling device can be used for leveling, and the vertical adjustment device can simultaneously adjust multiple embedded reinforcements 2 to be perpendicular to the horizontal plane while ensuring the integrity of the multiple embedded reinforcements 2; of course, other vertical leveling methods or methods of forming multiple embedded reinforcements 2 into an integral structure can also be used.

[0037] S3: Casting the area where the multiple embedded reinforcements 2 are located below the connecting plate 4; actually, when casting the multiple embedded reinforcements 2 below the connecting plate 4, when there are multiple connecting plates 4, the multiple connecting plates 4 can be flat steel bars, and the multiple flat steel bars are spaced apart, and the multiple connecting holes of the multiple flat steel bars are connected one by one with the multiple embedded reinforcements 2. When casting, the concrete can be directly cast from the top of the connecting plate 4 into the gap between two adjacent connecting plates 4, or cast from the side of the connecting plate 4, so that the cast concrete flows to the position where the multiple embedded reinforcements 2 are located at the lower part of the connecting plate 4. When the concrete contacts the lower part of the connecting plate 4, it is cast in place. After the concrete solidifies, the multiple embedded reinforcements 2 form a whole with the concrete cast for the first time, and a more stable connection is achieved.

[0038] S4: The embedded plate 5 is passed through the embedded rib 2 , and the embedded plate 5 is spaced above the connecting plate 4 .

[0039] It should be noted that when the embedded plate 5 is inserted before the embedded ribs 2, the multiple embedded ribs 2 basically maintain a vertical direction, that is, a direction perpendicular to the horizontal direction. The embedded plate 5 is connected to the multiple embedded ribs 2, and a space is left between the embedded plate 5 and the connecting plate 4, which can facilitate the adjustment of the embedded plate 5 and provide space for subsequent concrete pouring.

[0040] Furthermore, after the plurality of embedded bars 2 are vertically leveled, it can be ensured that the plurality of embedded bars 2 accurately pass through the embedded plate 5 and are fixedly connected to the plurality of embedded bars 2 .

[0041] S5: Casting the area where the multiple embedded bars 2 are located between the embedded plate 5 and the connecting plate 4.

[0042] That is, after the first pouring forms the first pouring structure 3, and the first pouring structure 3 is located between the bottom of the connecting plate 4 and the bottom surface of the connecting end plate 23, the second pouring structure 8 is continued to be poured between the upper part of the connecting plate 4 and the embedded plate 5, and the embedded plate 5 is used as the topmost structure, which is mainly used to support and connect the magnetic confinement controlled nuclear fusion device used for experiments. The device is large in size, and some equipment weighs more than 1000t; therefore, the embedded plate 5 is provided to support the magnetic confinement controlled nuclear fusion device, and the connecting plate 4 under the embedded plate 5 and the poured concrete structure can further improve the installation strength of the embedded structure and keep the embedded structure evenly stressed.

[0043] Therefore, the installation method of the embedded structure of the embodiment of the present invention forms a main frame by connecting the connecting plate 4 and multiple embedded ribs 2, and performs the first pouring on the main frame to improve the structural strength of the position below the connecting plate 4, and at the same time, the strength of the embedded structure as a support is improved by setting the embedded plate 5, and concrete is poured again between the embedded plate 5 and the connecting plate 4 to improve the force strength and force uniformity, so that larger equipment can be supported and connected on the embedded plate 5; in addition, the embedded ribs 2 are installed and poured separately from the embedded plate 5, etc., to ensure that the poured concrete flows more evenly, so that the force strength of the structure below the embedded plate 5 is uniform.

[0044] That is, the embedded structure with a larger size adopts the secondary casting method, which not only ensures that multiple positions can be cast in place during casting, but also facilitates the on-site installation and adjustment of the embedded plate 5 according to the situation of the embedded reinforcement 2, ensures the horizontality of the embedded plate 5, and realizes effective coordination and support with the magnetic confinement controlled nuclear fusion device to be supported or installed.

[0045] In practice, the embedded plate 5 is heavy, while the connecting plate 4 and the multiple embedded bars 2 are light. The light connecting plate 4 and the multiple embedded bars 2 can be easily installed, and the heavy embedded plate 5 can be hoisted by a crane, so the overall embedded structure is easy to install.

[0046] In some embodiments, S21: multiple embedded ribs 2 are vertically leveled through a connecting frame 1, the connecting frame 1 includes multiple first mounting holes 11; multiple embedded ribs 2 are correspondingly passed through the multiple first mounting holes 11 and connected to the connecting frame 1, and the connecting frame 1 is located above the connecting plate 4, and the connecting frame 1 is horizontally leveled so that the multiple embedded ribs 2 are vertically leveled.

[0047] In practice, the connecting frame 1 can be constructed by welding a plurality of mutually intersecting angle steels, such as Figure 1 As shown, each angle steel of the connecting frame 1 is provided with a plurality of first mounting holes 11, and a plurality of angle steels form a plurality of first mounting holes 11, and each embedded rib 2 is penetrated with a first mounting hole 11, so that the connecting frame 1 is connected with a plurality of embedded ribs 2, and a plurality of longer embedded ribs 2 are formed into an integral frame structure to ensure the integrity of the embedded structure. At the same time, when the upper part of the longer embedded ribs 2 is inclined, by adjusting the connecting frame 1 to be parallel to the horizontal plane, the plurality of embedded ribs 2 can be connected to the connecting frame 1 while also reducing the inclination of the embedded ribs 2, so that the embedded ribs 2 are perpendicular to the horizontal plane. After the connecting frame 1 is kept horizontal, the connecting frame 1 is fixedly connected with the plurality of embedded ribs 2.

[0048] In some embodiments, the connecting frame 1 is leveled by an adjustment assembly 6 , and the adjustment assembly 6 includes a first nut 61 and a second nut 62 .

[0049] S211: Install the first nut 61 on the embedded rib 2, connect the connecting frame 1 to the plurality of embedded ribs 2, and install the second nut 62 on the embedded rib 2 on the side of the connecting frame 1 away from the first nut 61.

[0050] In practice, threaded threads are provided on the outer periphery of the embedded reinforcement 2. After the first nut 61 is installed at the upper end of each embedded reinforcement 2, the connecting frame 1 is connected to the embedded reinforcement 2, and the second nut 62 is installed on the opposite side of the first nut 61. At this time, the first nut 61, the second nut 62 and the connecting frame 1 are movably connected to the embedded reinforcement 2, which can be prepared for movably adjusting the connecting frame 1 to be parallel to the horizontal plane.

[0051] S212: Level the connecting frame 1 by adjusting the first nut 61. When the connecting frame 1 is initially adjusted to be parallel to the horizontal plane, the first nut 61 may be rotated relative to the embedded ribs 2 so that the first nut 61 is against the connecting frame 1 and the position of the connecting frame 1 is adjustable; for example, among multiple embedded ribs 2, the middle embedded ribs 2 and the end embedded ribs 2 may be adjusted first, roughly until the connecting frame 1 is nearly parallel to the horizontal plane, and then the other first nuts 61 may be adjusted to correct the horizontality of the connecting frame 1, and finally keep the connecting frame 1 parallel to the horizontal plane.

[0052] S213: After the connecting frame 1 is leveled, the second nut 62 is locked. When the connecting frame 1 remains parallel to the horizontal plane, the second nut 62 is tightened continuously to lock the second nut 62, and the connecting frame 1 is fixedly connected with the first nut 61 and the second nut 62. At this time, the first nut 61 and the second nut 62 fixedly connected with the embedded ribs 2 are connected on both sides of the vertical direction of the connecting frame 1, and the first nut 61 and the second nut 62 can also strengthen the connection between the connecting frame 1 and the embedded ribs 2. In the process of adjusting the connecting frame 1, the multiple embedded ribs 2 are corrected so that the multiple embedded ribs 2 remain perpendicular to the horizontal direction, thereby improving the accuracy of the subsequent installation of the embedded plate 5, and also making the multiple embedded ribs 2 evenly stressed.

[0053] Then, concrete is poured under the connecting plate 4 to solidify the concrete, so as to further improve the integrity and stability of the embedded structure. It should also be noted that the multiple embedded bars 2 in the embodiment of the present invention include multiple first embedded bars 21 and multiple second embedded bars 22, wherein the length of the first embedded bars 21 is greater than the length of the second embedded bars 22. For example, the first embedded bars 21 are arranged at the middle position and the end position of the connecting plate 4 in the horizontal direction, and the second embedded bars 22 can be arranged at other positions. In the case of ensuring the strength, the material of the embedded bars 2 can be saved.

[0054] In some embodiments, S214: pouring the plurality of embedded bars 2 in the area below the connection plate 4, and after the poured concrete solidifies, removing the connection frame 1.

[0055] That is, the connecting frame 1 is mainly used to correct the embedded reinforcement 2 and to form a whole frame structure with multiple embedded reinforcements 2. After the first pouring and the poured concrete solidifies, the stability of the embedded structure is improved. After the poured concrete solidifies, the connecting frame 1 and the multiple embedded reinforcements 2 are partially cut off to facilitate the installation of the embedded plate 5 next time. For example, the embedded plate 5 is provided with multiple plate body mounting holes 51, each plate body mounting hole 51 corresponds to the embedded reinforcement 2, and after the embedded plate 5 is leveled, the plate body mounting holes 51 reserved on all the embedded plates 5 are filled with solder and plugged with welding. After the welding work is completed, pouring is carried out. That is, Figure 2 The connecting frame 1 is leveled so that the embedded reinforcement 2 is perpendicular to the horizontal plane, and after pouring the part below the connecting plate 4, the connecting frame 1 is cut off to form Figure 4 The state after removal, Figure 4 The embedded plate 5 has been placed and the second casting structure 8 has been carried out.

[0056] It should be noted that when the connecting frame 1 is cut, parts of the plurality of embedded ribs 2 may also be cut, and the position of cutting the embedded ribs 2 depends on the thickness of the embedded plate 5. Figure 4 As shown, the distance between the upper surface of the connecting plate 4 and the upper surface of the embedded plate 5 is the distance that the multiple embedded ribs 2 need to remain on the connecting plate 4, that is, at this time, the positions of the multiple embedded ribs 2 to be cut when the connecting frame 1 is cut can be selected according to this distance.

[0057] In some embodiments, pouring the area where the multiple embedded bars 2 are located below the connecting plate 4 includes: the length of the poured concrete along a first direction is greater than the extension length of the connecting plate 4 along the same direction, so that space is left at the end of the connecting plate 4.

[0058] In practice, after the first pouring of concrete, a reserved space 31 is provided above the connecting plate 4, and the first direction can be Figure 2 In the left and right directions, after the connecting frame 1 is cut off and the embedded plate 5 is connected to the plurality of embedded ribs 2, the embedded plate 5 is Figure 2The ends in the left and right directions of the connecting plate 4 will form an end space, and the ends in the left and right directions of the connecting plate 4 will also leave an end space. Concrete is poured at the end space left at the ends of the connecting plate 4 and the embedded plate 5, so that the concrete can flow from one side of the end to the space between the embedded plate 5 and the connecting plate 4, so as to pour the space between the embedded plate 5 and the connecting plate 4, and form the second pouring structure 8 between the embedded plate 5 and the connecting plate 4, that is, the structural design of the connecting plate 4, multiple embedded bars 2 and the embedded plate 5 is combined, and the second pouring is performed from the end to ensure the concrete pouring strength of the end, thereby improving the stability of the overall embedded structure. In other words, by limiting the length of the poured concrete in one direction to be greater than the length of the connecting plate 4 extending in the same direction during the first pouring, space for the next pouring of concrete can be left above the structure after the first pouring solidifies and at the end position of the connecting plate 4.

[0059] In some embodiments, inserting the embedded plate 5 before the embedded ribs 2 includes: selecting the embedded template 10 to compare and measure the position of the embedded ribs 2, drilling the template hole 101 on site, and processing the embedded plate 5 through the embedded template 10.

[0060] That is, after partially cutting off the connecting frame 1 and the embedded ribs 2, it is necessary to install the embedded plates 5 on the multiple embedded ribs 2, and the multiple embedded ribs 2 are corrected on site, formed as a whole and poured, etc. After the embedded template 10 is selected, the embedded template 10 is usually made of organic glass, and the embedded template 10 is opened on site, referring to Figure 5 As shown, Figure 5 It is a structural diagram of the embedded template 10, until it is ensured that the embedded template 10 can completely pass through all the exposed embedded ribs 2, and then the embedded template 10 is compared with the embedded plate 5 in the processing plant, and adjustments are made and the plate mounting holes 51 are processed.

[0061] That is, the embedded template 10 is used to compare the special-shaped embedded plate 5, and the template hole 101 is processed on the embedded template 10, so that the corresponding plate mounting hole 51 of the embedded plate 5 is processed in the processing plant. In this way, the processing error of the special-shaped large-sized embedded plate 5 can be reduced, thereby improving the installation accuracy of the embedded plate 5, and it can be processed according to the actual situation of multiple embedded reinforcements 2 on site, so as to process the embedded plate 5 that matches the current multiple embedded reinforcements 2, and realize the precise installation of large-sized and multiple embedded reinforcements 2 with the embedded plate 5 at the same time.

[0062] In some embodiments, the embedded plate 5 is arranged at intervals above the connecting plate 4, including: installing an adjusting nut 7 in part of the embedded ribs 2, installing the embedded plate 5 above multiple embedded ribs 2 and supported by the adjusting nut 7, and leveling the embedded plate 5 by adjusting the adjusting nut 7.

[0063] That is, after the first pouring of concrete and after the concrete solidifies, the connecting frame 1 and part of the embedded reinforcement 2 are cut off, and the adjusting nut 7 is installed on part of the embedded reinforcement 2 of the multiple embedded reinforcements 2 that have not been cut off, each adjusting nut 7 is threadedly matched with the corresponding embedded reinforcement 2, the bottom of the adjusting nut 7 can contact the connecting plate 4, and the embedded plate 5 is installed on the multiple embedded reinforcements 2, the bottom of the embedded plate 5 is in contact with the adjusting nut 7 in part of the embedded reinforcement 2, that is, the adjusting nut 7 can support the embedded plate 5, and the adjusting nut 7 can leave a pouring space between the embedded plate 5 and the connecting plate 4, and the space also serves as a space for installing and adjusting the embedded plate 5.

[0064] like Figure 4 As shown, the first embedded reinforcement 21 located in the middle and the end parts may be sleeved with an adjusting nut 7, and the plurality of second embedded reinforcements 22 may not be sleeved with the adjusting nut 7. By adjusting the vertical distance of the adjusting nut 7 along the embedded reinforcement 2, the horizontality of the embedded plate 5 may be adjusted. After the embedded plate 5 is kept horizontal, concrete is poured between the embedded plate 5 and the connecting plate 4 to form a second pouring structure 8. The better the horizontality of the embedded plate 5, the better the connection and support effect on the magnetic confinement controlled nuclear fusion device, and the entire embedded structure can have uniform strength and uniform force when supporting large-sized equipment.

[0065] In some embodiments, pouring the area where multiple embedded reinforcement bars 2 are located between the embedded plate 5 and the connecting plate 4 includes: pouring concrete between the embedded plate 5 and the connecting plate 4 along the sides of the connecting plate 4 and the embedded plate 5, so that the concrete flows between the embedded plate 5 and the connecting plate 4.

[0066] In practice, after the embedded plate 5 is connected and installed with a plurality of embedded ribs 2, the adjusting nut 7 between the embedded plate 5 and the connecting plate 4 leaves a pouring space between the embedded plate 5 and the connecting plate 4, and there are a plurality of connecting plates 4, which are spaced apart. When pouring the space between the embedded plate 5 and the connecting plate 4 from the side of the connecting plate 4 and the embedded plate 5, the concrete first flows along the side to between two adjacent connecting plates 4, and as the concrete continues to be injected, the concrete flows to the area between the connecting plate 4 and the embedded plate 5. Of course, concrete can be injected into the surrounding area of ​​the connecting plate 4 and the embedded plate 5, and the concrete flows along the surrounding area to between the connecting plate 4 and the embedded plate 5. When the concrete contacts the bottom of the embedded plate 5 and solidifies, the embedded plate 5 can form a support with high strength.

[0067] In some embodiments, the area where multiple embedded reinforcement bars 2 are located below the connecting plate 4 is cast to form a first casting structure 3, above the end of the first casting structure 3 is the building surface layer 9, and the area between the side of the embedded plate 5 and the building surface layer 9 is cast.

[0068] In practice, the building surface layer 9 is used to limit the casting height of the first casting structure 3. When casting along the area between the side of the embedded plate 5 and the building surface layer 9, the concrete first flows to the area between the side of the embedded plate 5 and the building surface layer 9, and gradually flows along the area to the area between the connecting plate 4 and the embedded plate 5. After the casting is completed, an end casting portion 81 is formed between the embedded plate 5 and the building surface layer 9. The thickness of the end casting portion 81 is greater than the thickness of the concrete cast between the connecting plate 4 and the embedded plate 5, thereby improving the reliability of the end of the entire embedded structure, making it difficult for the embedded structure to deform from the end, thereby improving the reliability of the entire embedded structure.

[0069] The embodiment of the present invention is suitable for special-shaped and large-sized embedded parts, and the embedded plate 5 is separated from the multiple embedded ribs 2 and the connecting plate 4, the connecting frame 1, etc., and then the embedded bracket is placed in advance into the concrete for pouring, so as to avoid using the supporting formwork of civil engineering to fix the large-sized embedded structure, and does not require a tower crane for lifting. The tower crane can generally only lift parts below five tons. During the installation of the fusion equipment, the embedded plate 5 can be lifted by a crane, and then installed and welded.
