Description

Technical Field

[0001] This invention relates to the field of steel plate wall construction technology, and more specifically, to a high-precision radiation-proof steel plate wall construction method. Background Technology

[0002] Currently, the construction of steel plate walls suffers from significant errors. For example, several patents, such as those with patent numbers 201610086898.8 and 201410545193.9, address this issue. Existing technologies typically use a spirit level placed on top of the steel plate wall for confirmation, leading to problems like large verticality errors and misalignment between adjacent plates. Therefore, ensuring the precise positioning of the steel plate wall's X, Y, and Z axes during construction, minimizing errors, and improving construction quality is the technical problem this invention aims to solve. Thus, it is necessary to propose a high-precision radiation-shielding steel plate wall construction method to at least partially address the problems existing in the prior art.

Detailed Implementation

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0045] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0046] like Figures 1-12 As shown, the present invention provides a method for constructing a high-precision radiation-shielding steel plate wall, comprising the following steps:

[0047] S1: Use a total station to lay out the outer contour line and control line of steel plate wall 1;

[0048] S2: The elevation of the steel plate wall 1 is corrected by placing the pad 2 between the embedded plate 3 and the steel plate wall 1;

[0049] S3: Adjust the planar displacement of steel plate wall 1 through the horizontal displacement adjustment device to correct the planar displacement of steel plate wall 1;

[0050] S4: Adjust the verticality of the steel plate wall 1 using the Z-axis positioning device 6 to correct the verticality of the steel plate wall 1;

[0051] S5: Welding is performed between adjacent steel plate walls 1 to fix the steel plate walls 1.

[0052] The working principle and beneficial effects of the above technical solution: By constructing the steel plate wall using the above method, precise adjustments can be made on three axes: X (adjusted by a horizontal displacement adjustment device), Y (adjusted by a horizontal displacement adjustment device), and Z (adjusted by a verticality adjustment device via a Z-axis positioning device and adjusted by a height adjustment device via a pad 2). This allows for the scientific and effective construction of building systems with extremely high installation precision requirements, ensuring project quality and accuracy.

[0053] In one embodiment, step S2 includes:

[0054] S201: Measure the top surface elevation of all embedded plates 3;

[0055] S202: Level the embedded plate 3 using the pre-prepared pad 2 based on the highest point of the embedded plate 3.

[0056] The horizontal displacement adjustment device includes: an X-axis positioning device 4 fixed to the side wall of the embedded plate 3 for positioning the plane of the steel plate wall 1; and a Y-axis positioning device 5 fixed to the embedded plates 3 on both sides of the steel plate wall 1 for positioning the two sides of the steel plate wall 1. The X-axis positioning device 4 and the Y-axis positioning device 5 are arranged in the normal direction.

[0057] The Y-axis positioning device 5 includes: a jack 51, a bracket 7 fixed on the embedded plate 3 for providing support for the jack 51, and a pad 52 disposed between the jack 51 and the side of the steel plate wall 1.

[0058] The Z-axis positioning device 6 includes:

[0059] The steel pipe 61 set on the embedded plate 3 is used to fix the steel plate wall 1 in the Z-axis direction;

[0060] The steel plate 62 and bolts 63 set at the top of the steel pipe 61 are used for connecting and fixing the steel pipe 61 to the steel plate wall 1 and for adjusting the verticality.

[0061] A magnetic plumb bob 64 is installed on the steel plate wall 1 to detect the verticality of the steel plate wall 1.

[0062] In step S5, after the steel plate wall 1 is straightened, a connecting plate 11 is installed between two adjacent steel plate walls 1 and welded to maintain the overall flatness of the steel plate wall 1.

[0063] The working principle and beneficial effects of the above technical solution are as follows: During construction, the height of the Z-axis is first adjusted by welding a pad 2 onto the embedded plate 3. The pad 2 can be selected with a height of 0.2mm to 20mm, thereby controlling the height of the steel plate wall 1.

[0064] Then, an X-axis positioning device 4 is installed on the embedded plate 3 or side wall where the steel plate wall 1 needs to be installed. The X-axis positioning device 4 can be made of L-shaped plate material for simple positioning. Although it is convenient to install, it can only achieve a simple and rough positioning effect. For construction conditions where the construction accuracy and verticality requirements are not high, L-shaped plate material can be used. If the construction accuracy and verticality requirements are high, the following X-axis positioning device 4 should be used for positioning in the X-axis direction and adjusting the verticality (see the following embodiments for details, which will not be repeated here. It should be noted that the X-axis positioning device 4 is not limited to the following embodiments or the L-shaped embodiments. As long as it can position the steel plate wall 1 in the X-axis direction, it is acceptable). Figure 2 As shown, the X-axis positioning device 4 is a flat plate.

[0065] The flat surface of the steel plate wall 1 is pressed tightly against the X-axis positioning device 4. The X-axis positioning device 4 can be connected to or abutted against the steel plate wall 1. The specific choice can be determined based on the accuracy and cost of the selected X-axis positioning device 4.

[0066] While installing the X-axis positioning device 4, the mounting base 7 is also installed, and the jack 51 is installed on the mounting base 7. After the steel plate wall 1 is pressed against the X-axis positioning device 4, the two sides are connected to the jack 51 through the pads 52, so as to avoid damage to the side wall of the steel plate wall 1. The steel plate wall 1 can be moved along the Y-axis direction by adjusting the jacks 51 on both sides.

[0067] The steel plate wall 1 can be translated in the horizontal direction by means of the X-axis positioning device 4 and the Y-axis positioning device 5.

[0068] Another embedded plate 3 is provided on the opposite side of the plane of the steel plate wall 1 and is fixedly connected to the steel pipe 61. The verticality of the steel plate wall 1 is adjusted by bolts 63.

[0069] When adjusting the verticality, a magnetic plumb bob 64 can be installed on the steel plate wall 1 to check the verticality.

[0070] To further increase the accuracy of verticality detection, a laser emission source that emits a strip of laser light towards the ground can be installed on the magnetic plumb bob 64, such as... Figure 5 As shown, when there is a problem with the verticality of the steel plate wall 1, the direction of verticality adjustment can be quickly and intuitively seen by the laser beam illuminating the ground. The laser emitted by the laser source can be a graduated laser (or the graduations can be marked on the top surface of the plumb bob for easy observation), and it is ensured that when the steel plate wall 1 remains vertical, the plumb bob at the bottom of the magnetic plumb bob 64 can precisely block part of the laser beam, such as... Figure 5 As shown in B, the magnetic plumb bob 64 can be used with the laser scale as a reference line, allowing the operator to visually see if there are any problems with the verticality.

[0071] After the final correction is completed, since the steel pipe 61 has fixed the steel plate wall, the horizontal displacement adjustment device (the X-axis positioning device 4 can be removed depending on the site requirements, the selected structure, and the connection method) and the magnetic plumb bob 64 can be removed.

[0072] Then, the two adjacent steel plate walls 1 are connected and welded together using the connecting plate 11.

[0073] In one embodiment, the X-axis positioning device 4 consists of a plate connector 41 connected to the steel plate wall 1 and a fixing member connected to the embedded plate 3;

[0074] The fastener includes a fixing plate 42 connected to the embedded plate 3, a triangular positioning member 43 disposed above the fixing plate 42, and a Y-axis rotating member 44 connected to the positioning member 43.

[0075] The plate connector 41 is movably connected to the Y-axis rotating component 44.

[0076] One side of the plate connector 41 is connected to the steel plate wall 1, and the other side is provided with a hook 45 for movably connecting with the Y-axis rotating component 44, and a threaded push rod 46 that is threadedly connected to the steel plate wall 1. One end of the threaded push rod 46 is connected to the steel plate wall 1 through a rotatable threaded sleeve 47 provided on the plate connector 41, and the other end abuts against the Y-axis rotating component 44.

[0077] The working principle and beneficial effects of the above technical solution are as follows: Since the X-axis positioning device 4 limits the steel plate wall 1 in the X-axis direction, in order not to affect the translation of the steel plate wall 1 in the Y-axis direction and the adjustment of its verticality, the plate connector 41 of the X-axis positioning device 4 can be connected to the steel plate wall 1 by abutment, or it can be fixedly connected to the steel plate wall 1 after the construction is completed. The specific situation shall be subject to the on-site construction.

[0078] This embodiment provides two implementation methods: one is to set the X-axis positioning device 4 on one side, and the other is to set the X-axis positioning device 4 symmetrically on both sides of the steel plate wall 1.

[0079] Taking the single-sided X-axis positioning device 4 as an example, after the fixing plate 42 is connected to the embedded plate 3, the surface of the steel plate wall 1 is attached to the plate connector 41. At this time, it is possible to connect the plate connector 41 to the steel plate wall 1 by using a pin (this implementation can also fix the bottom of the steel plate wall 1, thereby preventing the verticality from changing when it moves along the Y-axis. It is usually used in construction environments where the verticality requirement is not high, or in construction methods where the verticality is adjusted first and then the horizontal displacement is adjusted). Alternatively, it can be left unconnected (in this implementation, when the steel plate wall 1 moves along the Y-axis, the Y-axis rotating part 44 will still rotate relative to the positioning part 43 under the action of friction, but the difference is that it will not affect the subsequent adjustment of verticality).

[0080] When the steel plate wall 1 is translated in the Y-axis direction, the plate connector 41 can move with the steel plate wall 1 and rotate relative to the positioning member 43 through the Y-axis rotating member 44.

[0081] When adjusting the verticality, the plate connector 41 can be engaged with the protruding rotating shaft on the Y-axis rotating member 44 via the hook 45 and rotate relative to it, so that when adjusting the verticality, the plate connector 41 can always be in contact with the surface of the steel plate wall 1 to limit its position.

[0082] When X-axis positioning devices 4 are symmetrically installed on both sides of the steel plate wall 1, such as Figure 8 As shown, the spacing and verticality between the two plate connectors 41 need to be adjusted in advance to facilitate the insertion of the steel plate wall 1.

[0083] In this embodiment, the threaded sleeve 47 provided on the plate connector 41 can be rotated, so that the threaded push rod 46 can be extended or shortened, thereby increasing the friction between the hook 45 and the rotating shaft protruding on the Y-axis rotating member 44, so that the perpendicularity of the plate connector 41 can be preset, and avoids a large deviation in perpendicularity when the steel plate wall 1 is attached to the plate connector 41.

[0084] In one embodiment, the mounting base 7 has a U-shaped structure. The bottom surface of the mounting base 7 is connected to the embedded plate 3. A U-shaped groove for engaging the jack 51 is provided on the U-shaped sidewall of the mounting base 7. A fixing tie 511 is provided on the jack 51, and the fixing tie 511 is selectively placed in the U-shaped groove on the U-shaped sidewall of the mounting base 7. A locking hook 71 and a engaging hook 72 are axially connected to the inner wall of the mounting base 7. The engaging hook 72 selectively abuts against the fixing tie 511 of the jack 51. Both the locking hook 71 and the engaging hook 72 are connected to the inner sidewall of the U-shape of the mounting base 7 through torsion springs. A threaded rod 73 is also provided on the mounting base 7. The threaded rod 73 is threadedly connected to the mounting base 7. One end of the threaded rod 73 extends to the outside of the mounting base 7, and the other end selectively abuts against the locking hook 71.

[0085] The locking hook 71 consists of a shaft connection part 711 that is axially connected to the inner wall of the card seat 7, a locking hook part 712 located above the shaft connection part 711, and a push top 713 located below the shaft connection part 711 that selectively abuts against the threaded rod 73. The shaft connection part 711 is connected to the inner wall of the card seat 7 by a torsion spring.

[0086] The latching hook 72 consists of a lifting part 721 that is axially connected to the inner wall of the card seat 7, a latching part 722 located above the lifting part 721, and a locking part 723 located above the latching part 722 that selectively latches with the locking hook part 712. The lifting part 721 is connected to the inner wall of the card seat 7 by a torsion spring.

[0087] The working principle and beneficial effects of the above technical solution: The bracket 7 is used to provide support for the jack 51. In order to reduce the difficulty of operation and improve the support for the jack 51, the bracket 7 needs to meet the requirements of quick disassembly and provide sufficient support force. At the same time, since the embedded plate 3 is located on both sides of the steel plate wall 1, another steel plate wall 1 needs to be installed on it after construction. Therefore, it is also necessary to ensure that the bracket 7 provides sufficient support force while minimizing damage to the embedded plate 3. Therefore, the commonly used method of setting heavy objects on the embedded plate 3 is no longer suitable for the construction method of this invention, because it is difficult to move heavy objects. Therefore, this embodiment provides a bracket 7 to solve the above problems.

[0088] In this embodiment, the card holder 7 adopts a U-shaped structure, and its bottom is connected to the embedded plate 3. Multiple screws can be used for connection to disperse the force of the card holder 7 on the embedded plate 3 and reduce the damage of the jack 51 to the embedded plate 3.

[0089] Meanwhile, the jack 51 should be a model with a fixing tie rod 511. It should be noted that the fixing tie rod 511 described in this invention is only a structure that can be snapped into the U-shaped groove of the card seat 7, and can be rod-shaped, strip-shaped, etc.

[0090] like Figure 12 As shown in F, G, and H, during construction, the bottom surface of the mounting base 7 is connected to the embedded plate 3. Then, the fixing tie rod 511 of the jack 51 is placed into the U-shaped groove on the side wall of the mounting base 7 from top to bottom. During the process of the fixing tie rod 511 falling, it will abut against the lifting part 721 of the locking hook 72, causing the locking hook 72 to rotate until the bottom of the fixing tie rod 511 abuts against the bottom of the U-shaped groove on the side wall of the mounting base 7. At this time, the locking part 722 of the locking hook 72 abuts against the top of the fixing tie rod 511, and the locking part 723 hooks and locks the locking hook part 712. The torsion spring of the locking hook 72 is under stress.

[0091] like Figure 12 As shown in Figures I, J, and K, after construction is completed, the threaded rod 73 is rotated so that its end abuts against and pushes the top 713 of the locking hook 71, thereby causing the locking hook 71 to rotate and the torsion spring of the locking hook 71 to be stressed until the locking hook part 712 separates from the locking part 723. Under the action of the torsion spring of the locking hook 72, the locking hook 72 is reset, lifting the fixing tie 511, so that the operator can directly remove the jack 51. Then the threaded rod 73 is reset, and under the action of the torsion spring of the locking hook 71, the locking hook 71 is reset.

[0092] like Figure 10 , 11 As shown, the hook portion 712 is a downwardly curved hook shape, and the locking portion 723 is a slightly upwardly curved hook shape. The locking portion 723 can engage with the hook of the hook portion 712 to achieve engagement. The hook shapes of both the hook portion 712 and the locking portion 723 are arc-shaped transitions, which allows the hook portion 712 and the locking portion 723 to both lock and separate, preventing a situation where they are locked and cannot be separated.

[0093] The torsion spring of the locking hook 71 has one end set on the inner side wall of the card seat 7 and the other end set on the locking hook 71. As long as the locking hook 71 can rotate, the torsion spring can be subjected to force.

[0094] The torsion spring of the snap hook 72 has one end set on the inner side wall of the snap seat 7 and the other end set on the snap hook 72. As long as the snap hook 72 can rotate, the torsion spring can be subjected to force.

[0095] The threaded rod 73 is located at one end of the card holder 7 and is threadedly connected to the card holder 7.
