Description

Technical Field

[0001] This invention relates to a method for constructing embedded parts, specifically a method for high-precision fixing of multiple embedded parts on the same plane. Background Technology

[0002] In industrial construction, multiple embedded parts often need to be fixed on the top surface of a piece of equipment. The installation and positioning of these embedded parts is a key challenge in construction control. The higher the precision of the instruments and equipment, the more accurate the installation and positioning of the embedded parts, and the greater the construction difficulty. The key and challenging aspect of the research will be to determine what measures and methods to take to ensure that the installation quality and precision of multiple embedded parts meet the equipment installation precision requirements.

[0003] Conventional construction methods for embedded parts involve prefabricating the parts and then transporting them to the site for installation. Embedded parts are typically installed after the structural reinforcement is largely completed, involving positioning, elevation adjustment, and reassembly of the structural reinforcement, making the process quite challenging in practice. While high-standard measurements and reinforcement are performed on the embedded parts before concrete pouring, variations in flatness and elevation during pouring are unavoidable due to factors such as vibration, worker foot traffic, and concrete settlement. Therefore, conventional methods struggle to control the flatness and elevation of the embedded parts, frequently resulting in errors. Addressing these errors requires significant time, impacting the construction schedule.

[0004] While existing high-precision embedded part installation technologies have addressed the construction accuracy issues of embedded parts to some extent, numerous challenges remain. These technologies generally suffer from insufficient embedded part stability, difficulty in precisely adjusting elevation and levelness during welding, difficulty in controlling relative errors between multiple embedded parts, and the impact of concrete pouring on embedded part accuracy. Furthermore, existing methods are often complex to install, involve cumbersome position adjustment procedures, and require highly skilled workers, resulting in low construction efficiency. Although some technologies have made breakthroughs in terms of economy, convenience, or quality assurance, they have not yet fully resolved all the challenges in the high-precision embedded part installation process, particularly in the construction positioning and long-term stability of multiple embedded parts on the same plane, which still requires improvement.

[0005] Patent CN110106984A discloses a high-precision embedded part installation method, which is economical, convenient, and ensures construction quality and progress. However, it struggles to address the stability issues associated with heavy embedded parts. Furthermore, the method cannot precisely adjust the elevation and levelness of the embedded parts during welding, and post-pouring can easily generate cold fronts around the embedded parts, leading to cracking under dynamic loads. Additionally, while this patent controls installation accuracy to some extent by controlling individual embedded parts, it is difficult to control the installation accuracy of multiple embedded parts simultaneously.

[0006] Patent CN102287058B provides a method for installing and leveling large-plane, high-precision embedded parts, solving the problems of low construction efficiency and inability to achieve the required dimensional and positional accuracy during embedded part installation. However, this invention struggles to address the impact of construction loads during concrete pouring on the accuracy of embedded parts, resulting in complex installation and cumbersome position adjustment procedures. Furthermore, while this patent controls installation accuracy to some extent by controlling individual embedded parts, it faces significant challenges in simultaneously controlling multiple embedded parts.

[0007] Patent CN110031173A provides a high-precision heavy-duty track embedding construction method, which solves the problem of construction positioning of large, high-precision embeddings, making the installation of simulated collision test equipment very smooth. However, the construction steps of this invention are complicated and lengthy, the installation is complex, and the position adjustment process is cumbersome, requiring skilled workers. In addition, this patent controls the installation accuracy to some extent by controlling a single embedding, but it is difficult to control multiple embeddings simultaneously. Summary of the Invention

[0008] To address the aforementioned issues, a high-precision fixing method for multiple embedded parts on the same plane is provided, aiming to effectively solve the problems existing in the prior art.

[0009] The specific technical solution is as follows: High-precision fixing methods for multiple embedded parts on the same plane include: Tie the reinforcing steel bars of the equipment platform, and install the pouring formwork around the reinforcing steel bars of the equipment platform; Erect a support frame around the pouring formwork; Adjust the longitudinal beams to ensure that their elevation and level meet the accuracy requirements, and then install the longitudinal beams onto the support frame. Adjust the spacing of the crossbeams according to the design requirements, and fix the crossbeams to the longitudinal beams; Adjust the embedded parts so that their lateral position meets the design requirements, and then install the embedded parts on the crossbeam; After pouring concrete and ensuring it is properly cured, remove the longitudinal beams, transverse beams, support frames, and pour the formwork.

[0010] Furthermore, the feature is that the support frame is a scaffold.

[0011] Furthermore, a top support is installed on the uprights of the scaffold near the steel reinforcement of the equipment platform, and the longitudinal beams are installed on the scaffold through the top support.

[0012] Furthermore, the longitudinal beams are spot-welded to the top support.

[0013] Furthermore, a longitudinal beam groove is installed on the longitudinal beam, and a fastening bolt is installed in the longitudinal beam groove. The crossbeam is installed on the longitudinal beam through the fastening bolt.

[0014] Furthermore, longitudinal beams are equipped with longitudinal beam scale lines, and the spacing of the crossbeams is adjusted by using these scale lines.

[0015] Furthermore, the longitudinal beam graduation lines are set to extend along the longitudinal beam groove.

[0016] Furthermore, a crossbeam groove is installed on the crossbeam, and a second fastening bolt is installed in the crossbeam groove. The embedded part is installed on the crossbeam by the second fastening bolt.

[0017] Furthermore, the crossbeam is equipped with crossbeam scale lines, and the embedded parts are adjusted in lateral position by means of the crossbeam scale lines.

[0018] Furthermore, the scale lines on the crossbeam extend along the crossbeam groove.

[0019] The beneficial effects of the above scheme are: 1) In view of the problems of insufficient consistency and stability of welding between embedded parts and structural steel bars in the existing technology, and difficulty in adjusting the elevation and level, the present invention adopts the method of erecting scaffolding on both sides of the equipment platform, and uses adjustable top supports to support the weight of longitudinal beams, transverse beams and embedded parts, and ensures that the embedded parts are not connected to the structural steel bars. This can effectively avoid the problem of changes in the plane position and elevation of embedded parts caused by vibrating rods, construction workers stepping on them and the settlement of the concrete structure itself, and significantly enhance the installation stability and accuracy maintenance of heavy embedded parts. 2) In existing technologies, reinforcing and leveling multiple embedded parts individually on the same plane is a cumbersome process, and the overall levelness is difficult to control. This invention connects all embedded parts into a whole through crossbeams and longitudinal beams, and locks them on the same plane in advance, achieving the goal of simultaneously and quickly adjusting the elevation and levelness of multiple embedded parts, thus improving the efficiency and accuracy of leveling. 3) In existing technologies, the horizontal position of multiple embedded parts on the same plane is adjusted by measuring with a steel ruler. This involves numerous construction steps, large relative errors, and makes it difficult to simultaneously control the relative position of multiple embedded parts to meet high precision requirements. This invention, by setting grooves and scale lines on the crossbeam and rectangular bolt holes on the longitudinal beam, enables the relative movement of a single embedded part in the horizontal direction, providing multi-dimensional and high-precision flexible adjustment capabilities.

[0022] 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.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0025] like Figures 1 to 4 As shown, the high-precision fixing method for multiple embedded parts on the same plane provided in the embodiments of the present invention includes: Tie the reinforcing steel bars of the equipment platform, and install the pouring formwork around the reinforcing steel bars of the equipment platform; Erect scaffolding around the outside of the casting formwork (the stability and load-bearing capacity of scaffolding 1 are mainly controlled by the spacing of the uprights and the number of diagonal braces; specific erection requirements can be found in relevant specifications). After the scaffolding is erected, an adjustable top support 2 is installed on the upright near the equipment platform steel bar 3. The elevation of the top support 2 is adjusted so that the elevation and level of the longitudinal beam 5 meet the accuracy requirements. At this time, a welding machine is used to selectively spot weld the top support 2 and the longitudinal beam 5 to achieve the purpose of fixing the longitudinal beam 5. After the longitudinal beam 5 is fixed, control reference points are set on the longitudinal beam 5. The spacing of the cross beam 6 is adjusted by the longitudinal beam scale line 8. After the spacing of the cross beam 6 is adjusted, the cross beam 6 and the longitudinal beam 5 are locked by fastening bolt 1, such as T-shaped combination bolt 9, through the longitudinal beam groove 7 to complete the cross beam fixing. After the crossbeam 6 is fixed, tighten the second bolt, such as the hexagonal combination bolt 10, through the crossbeam groove 12, insert the bolt of the hexagonal combination bolt 10 into the bolt hole 13 on the embedded part 4 and tighten it. Control the lateral position of the embedded part 4 through the scale line 11 of the crossbeam. After the lateral position is adjusted, use the nut of the hexagonal combination bolt 10 to lock the embedded part 4 to the crossbeam 6 to complete the fixing of the embedded part 4. After the embedded part 4 is fixed, re-measure whether the installation of the embedded part 4 meets the accuracy requirements. If it does not meet the requirements, adjust the position of the top support 2, T-shaped combination bolt 9, and hexagonal combination bolt 10 until the accuracy requirements are met. Then pour concrete, and after curing, remove the longitudinal beam, cross beam, support frame, and pour the formwork.

[0026] To address the issues of insufficient consistency and stability in the welding of embedded parts to structural steel bars, and the difficulty in adjusting elevation and levelness in existing technologies, this invention employs scaffolding erected on both sides of the equipment platform. Adjustable top supports bear the weight of the longitudinal beams, transverse beams, and embedded parts, while ensuring that the embedded parts are not connected to the structural steel bars. This effectively avoids changes in the plane position and elevation of the embedded parts caused by factors such as vibration of the vibrator, trampling by construction workers, and settlement of the concrete structure itself, significantly enhancing the installation stability and accuracy retention of heavy embedded parts.

[0027] In existing technologies, reinforcing and leveling multiple embedded parts individually on the same plane is a cumbersome process, and the overall levelness is difficult to control. This invention connects all embedded parts into a single unit using horizontal and vertical beams, and pre-locks them onto the same plane, achieving the goal of simultaneously and quickly adjusting the elevation and levelness of multiple embedded parts, thus improving the efficiency and accuracy of leveling. In existing technologies, the horizontal position of multiple embedded parts on the same plane is adjusted by measuring with a steel ruler. This involves numerous construction steps, significant relative errors, and makes it difficult to simultaneously control the relative position of multiple embedded parts to meet high precision requirements. This invention, by setting grooves and scale lines on the crossbeam and rectangular bolt holes on the longitudinal beam, enables the relative movement of a single embedded part in the horizontal direction, providing multi-dimensional and high-precision flexible adjustment capabilities.

[0028] The above description is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
