Description

Technical Field

[0001] This invention relates to the field of substation engineering construction technology, and in particular to a pre-embedded component support structure and construction method that facilitates rapid construction. Background Technology

[0002] In substation construction, electrical equipment such as main transformers, GIS, and SVG need to be fixed to the top of the concrete foundation using embedded parts. The installation accuracy of these embedded parts directly affects the quality of the rigid connection between the various components of the equipment. Their position, elevation, and levelness deviations must all be controlled within preset ranges; otherwise, it will lead to difficulties in equipment installation and even affect operational reliability. Therefore, the installation process of embedded parts for electrical equipment has always been a key focus in the field of power foundation construction.

[0003] Currently, the installation of embedded parts for electrical equipment in China generally adopts traditional construction techniques. This technique uses a single concrete support as a work unit. First, the foundation reinforcement and stirrup reinforcement of the support are tied to the foundation layer. The stirrup reinforcement is used to support the upper steel mesh, ensuring the position of the reinforcement and the thickness of the concrete cover. Then, the construction workers place the embedded part on each support, using tools such as a tape measure and level for initial positioning. The embedded part is temporarily tied and fixed to the foundation reinforcement or stirrup reinforcement. The center coordinates and top elevation of the embedded part are then checked again. After confirmation, the embedded part is firmly welded to the steel mesh. All the above steps are repeated for all supports until all embedded parts are installed.

[0004] Traditional construction methods involve independent construction of each support pier, requiring repetitive processes such as initial positioning, binding, verification, and welding for each embedded component. Furthermore, the varying shapes and sizes of the supports result in a large workload for surveying, setting out, and position adjustment, making it difficult to shorten the construction period. The embedded components are fixed to the reinforcing mesh by welding, but the heat generated during welding damages the galvanized anti-corrosion layer on the surface of the embedded components, and the weld seams are prone to corrosion weak points, directly affecting the durability of the embedded components. Simultaneously, welding deformation further increases positional deviations, and welded embedded components cannot be fine-tuned. Once the deviation exceeds the limit, cutting and re-welding are necessary, resulting in high rework costs.

[0005] Existing technologies include reusable external scaffolding support structures for embedded parts. These structures support embedded parts using independent supports, which can reduce on-site welding work to some extent. However, their overall size is large, requiring space around the supports for installation. When multiple pieces of equipment need to be centrally located on the construction site, the spacing between adjacent concrete supports is small, and the narrow space between the supports cannot accommodate the external scaffolding support structure. This solution is difficult to implement in such conditions. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a pre-embedded component support structure and construction method that facilitates rapid construction, thereby solving the problems of cumbersome procedures, difficulty in ensuring positioning accuracy, easy damage to the anti-corrosion layer, and difficulty in laying out support structures under space-constrained conditions in existing construction processes, and realizing rapid construction and high-precision control of pre-embedded component installation.

[0007] To achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

[0008] An embedded part support structure for easy and rapid construction includes: a support frame and a fixing clamp; the support frame is cast in a concrete foundation and includes a bottom frame, support legs and a top frame, the bottom frame is fixed on a concrete pier, the support legs are connected between the bottom frame and the top frame, and the support legs can adjust the lifting and lowering of the top frame; the fixing clamp includes a support base and an adjusting member, the support base is fixed on the top frame, the embedded part is placed on the support base, and the adjusting member is installed on the support base with its inner end abutting against the edge of the embedded part.

[0009] Optionally, the support leg includes an upper support leg and a lower support leg. The lower support leg is connected to the bottom frame, and the upper support leg is connected to the top frame. A fixing plate is provided on the top of the lower support leg, and a receiving gap is formed between the fixing plate and the lower support leg body. The upper support leg is inserted into the receiving gap, and a fixing screw is installed on the fixing plate. The inner end of the fixing screw abuts against the lower support leg.

[0010] Optionally, the main body of the support frame is welded from angle steel, the fixing plate is set on the inner side of the lower leg angle steel and forms an L-shaped receiving gap with the angle steel, and the angle steel of the upper leg is inserted into the L-shaped receiving gap.

[0011] Optionally, the support frame is a cubic frame structure, and the bottom frame and top frame are both rectangular structures. Leveling screws are installed at the four corners of the bottom frame, and the bottom end of the leveling screw can abut against the support to adjust the level of the embedded part.

[0012] Optionally, the support frame is further provided with support beams, which are arranged in the middle of the top frame in a grid pattern. Some of the fixing clamps are fixed to the outer frame of the top frame, and some of the fixing clamps are fixed to the support beams inside the top frame.

[0013] Optionally, the support base includes a base plate, a vertical plate, and a support plate. The base plate is fixed to the top frame, the vertical plate is disposed on the base plate, and the support plate is disposed on one side of the vertical plate. The support plate is parallel to the base plate and has a set distance from the base plate. The embedded part is placed on the support plate.

[0014] Optionally, the top surface of the vertical plate is not higher than the top surface of the embedded part.

[0015] Optionally, the adjusting component is an adjusting screw, which is mounted on the vertical plate and located on the upper side of the support plate.

[0016] Optionally, four embedded parts are installed on each of the support frames. The four embedded parts are located at the four corners of the support frame, and each embedded part is fixed by four fixing clamps distributed around the embedded part.

[0017] This invention also provides a construction method for a pre-embedded component support structure that facilitates rapid construction, comprising the following steps: Place the support frame at the designated position on the concrete pier, so that the bottom frame sits on the pier, and place the embedded parts on the fixing clamp. Adjust the leveling screws on the bottom frame to bring the embedded parts to a horizontal position, and then fix the bottom frame to the support. Adjust the length of the support legs according to the design elevation of the embedded part, so that the embedded part rises or falls to the set elevation; Rotate the adjusting screw to push the embedded part, adjust the embedded part to the preset position, and lock the embedded part on the support base; Pour concrete to embed the support frame entirely within the foundation, with some of the embedded parts exposed on the foundation.

[0018] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages: The support structure of this invention integrates the support frame as a single component within the concrete foundation. The support frame itself becomes part of the concrete foundation, not occupying external space of the piers. Therefore, even small distances between adjacent piers do not restrict the installation of this structure and even enhance the foundation's bearing capacity. The bottom frame, fixed to the piers, provides the installation base for the support frame. The adjustable support legs allow the top frame to reach different elevations, and the support base, fixed to the top frame, establishes a force transmission path between the top frame and the embedded part. The adjusting component applies a thrust from the edge of the embedded part, working in conjunction with the support base's support function to achieve bidirectional constraint on the horizontal position of the embedded part. By employing a fixing method where the support base supports the embedded part and the adjusting component pushes against the edge of the embedded part, the connection between the embedded part and the support frame is detachable and requires no welding. The anti-corrosion layer of the embedded part is fully preserved, and the adjusting component can push the embedded part horizontally, making position correction a repeatable process.

[0019] Advantages of additional aspects of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Embedded parts; Detailed Implementation It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0022] Example 1 This embodiment proposes a high-efficiency and high-precision embedded part support structure, which improves the construction speed and positioning accuracy of embedded parts. At the same time, the use of prefabricated construction method ensures the structural safety of the embedded part support structure, reduces transportation costs, and improves the overall construction speed of the substation.

[0023] like Figure 1 As shown, the support structure of the embedded part 3 includes a support frame 1 and a fixing clamp 2; as Figure 2As shown, the support frame 1 is cast within a concrete foundation and includes a bottom frame 11, support legs 12, and a top frame 13. The bottom frame 11 is fixed to a concrete pier, and the support legs 12 connect the bottom frame 11 and the top frame 13, and the support legs 12 can adjust the lifting and lowering of the top frame 13; Figure 4 , Figure 5 As shown, the fixing clamp 2 includes a support base and an adjusting member. The support base is fixed on the top frame 13, the embedded part 3 is placed on the support base, and the adjusting member is installed on the support base with its inner end abutting against the edge of the embedded part 3.

[0024] The support frame 1, serving as the main skeleton of the entire structure, is embedded in the concrete foundation using a cast-in-place method. This forms an integral load-bearing structure with the concrete foundation, improving the foundation's load-bearing capacity and resistance to deformation. Support legs 12 connect the bottom frame 11 and the top frame 13, and also feature length adjustment, allowing the top frame 13 to be raised or lowered, thereby adjusting the installation elevation of the embedded part 3. This adjustable design solves the problem of accurately controlling the elevation of the embedded part 3 in traditional construction processes, avoiding elevation deviations caused by pier height errors or foundation settlement. The fixing clamp 2 provides a stable placement platform for the embedded part 3. The embedded part 3 is placed directly on the support base without welding to the support frame 1, avoiding damage to the galvanized anti-corrosion layer of the embedded part 3 from the high temperatures of welding and ensuring its long-term corrosion resistance. Adjustable components allow for fine-tuning the horizontal positioning of the embedded part 3, achieving precise alignment of its center coordinates.

[0025] As an independent frame structure, the support frame 1 is directly arranged on the piers, occupying little space. It can be implemented in a limited space where the piers are densely arranged, overcoming the shortcomings of the external frame support structure, which has a large footprint of the bottom legs and is difficult to arrange in dense areas.

[0026] The combination of support frame 1 and fixing clamp 2 forms an independent support system for embedded part 3. Support frame 1 can be prefabricated in the factory and transported to the site for installation, which reduces the amount of on-site steel bar binding and welding work and shortens the construction cycle.

[0027] Based on commonly used specifications, various support frames of the same size are calculated to be suitable for foundations of different specifications. When calculating the size of the support frame, the size of the fixing fixture 2 should be considered to ensure that the final elevation and center coordinates of the embedded parts are accurate, and the machining error of all rod dimensions is no more than 1mm.

[0028] like Figure 3As shown, the support leg 12 includes an upper support leg 122 and a lower support leg 121. The lower support leg 121 is connected to the bottom frame 11, and the upper support leg 122 is connected to the top frame 13. A fixing plate 123 is provided on the top of the lower support leg 121. A receiving gap is formed between the fixing plate 123 and the body of the lower support leg 121. The upper support leg 122 is inserted into the receiving gap, and a fixing screw 124 is installed on the fixing plate 123. The inner end of the fixing screw 124 abuts against the lower support leg 121.

[0029] The upper support leg 122 and the lower support leg 121 are connected by a plug-in joint. During assembly, the upper support leg 122 is inserted into the receiving gap, and the height of the support leg 12 can be initially determined. This method is more efficient than welding or flange connections. The inner end of the fixing screw 124 abuts against the lower support leg 121. Tightening the fixing screw 124 locks the relative position of the upper support leg 122 and the lower support leg 121. Loosening the screw allows for readjustment of the height, enabling stepless adjustment of the length of the support leg 12. The receiving gap formed between the fixing plate 123 and the body of the lower support leg 121 encloses the upper support leg 122 on three sides, providing guidance and limiting in the horizontal direction. The plug-in structure and the fixing screw 124 work together to meet the needs of rapid on-site assembly while ensuring the stability of the support leg 12 under vertical loads.

[0030] The main frame of the support frame 1 is made of ∠50×5 angle steel. The angle steel is connected by full welding. Using angle steel as the main body material of the support frame 1 is a common choice in the field of power civil engineering. It has high strength and is easy to weld, ensuring its strength, rigidity and stability, and ensuring that it does not deform or move during the concrete pouring process.

[0031] The fixing plate 123 is located inside the angle steel of the lower support leg 121, forming an L-shaped receiving gap with the angle steel. The angle steel of the upper support leg 122 is inserted into the L-shaped receiving gap. The cross-sectional shape of the angle steel makes its two edge plates form a natural guide surface. The L-shaped receiving gap is formed by one edge plate of the angle steel of the lower support leg 121 and the fixing plate 123. When the angle steel of the upper support leg 122 is inserted, its two edge plates contact the edge plate of the angle steel of the lower support leg 121 and the fixing plate 123 respectively, thus being constrained in both directions. The welding of the angle steel and the L-shaped insertion structure work together to make the support frame 1 have high overall rigidity and not easily deformed under the lateral pressure generated by concrete pouring, thereby ensuring the positional accuracy of the embedded part 3.

[0032] like Figure 2 As shown, the support frame 1 is a cubic frame structure, and the bottom frame 11 and the top frame 13 are both rectangular structures. Leveling screws 15 are installed at the four corners of the bottom frame 11. The bottom end of the leveling screw 15 can abut against the support pier to adjust the level of the embedded part 3.

[0033] When the bottom frame 11 is located on the surface of the pier, due to the possible flatness deviation in the pier construction, the support frame 1 may be inclined. When the leveling screw 15 is screwed out, it can lift a corner of the bottom frame 11, causing the bottom frame 11 to be disengaged from the surface of the pier. By adjusting the different screwing-out lengths of the four leveling screws 15, the support frame 1 can be adjusted to be horizontal.

[0034] The support frame 1 is further provided with a support beam 14, which is arranged in the middle of the top frame 13 and is arranged in a crisscross pattern in a grid shape. Some fixing fixtures 2 are fixed on the outer frame of the top frame 13, and some fixing fixtures 2 are fixed on the support beam 14 inside the top frame 13.

[0035] The top frame 13 serves as the installation base for the fixing fixture 2. When multiple embedded parts 3 need to be installed on the support frame 1 simultaneously, the outer frame alone cannot provide sufficient support points for the embedded parts 3 in the middle of the top frame 13. The grid-shaped support beam 14 divides the area of the top frame 13 into multiple small cells. The support beam 14 itself is welded to the outer frame of the top frame 13 to form an integral body, providing sufficient support points for the embedded parts 3 and simultaneously increasing the flexural rigidity of the top frame 13. The fixing fixture 2 can be arranged either on the side beam of the outer frame or on the support beam 14. For the case of installing four embedded parts 3 on the same support frame 1, the fixing fixtures 2 at the four corners of each embedded part 3 can be fixed on different beams respectively, enabling the embedded part 3 to be evenly stressed around its perimeter.

[0036] As Figure 5 shown, the support base includes a bottom plate 21, a vertical plate 22, and a support plate 24. The bottom plate 21 is fixed on the top frame 13. The vertical plate 22 is provided on the bottom plate 21. The support plate 24 is provided on one side of the vertical plate 22. The support plate 24 is parallel to the bottom plate 21 and has a set distance from the bottom plate 21. The embedded part 3 is placed on the support plate 24.

[0037] The support base is in the shape of an upside-down "T" character, prefabricated and processed in the factory, and fully welded to the support frame 1 on-site. There is a gap between the surface of the top frame 13 and the support plate 24. This gap becomes a channel for concrete to enter the bottom of the embedded part 3 during concrete pouring. If the support plate 24 is directly close to or even coplanar with the bottom plate 21, there will be a closed space between the bottom of the embedded part 3 and the top frame 13, making it difficult for concrete to fill. After the support plate 24 is raised, the bottom surface of the embedded part 3 is disengaged from the surface of the top frame 13, and concrete can flow in from the side under the embedded part 3, ensuring that the bottom of the embedded part 3 is filled.

[0038] When installing electrical equipment, the equipment base is usually directly located on the top surface of the embedded part 3 and connected by bolts. If the vertical plate 22 protrudes above the top surface of the embedded part 3, it will interfere with the equipment base, causing the equipment not to be able to fit tightly against the embedded part 3 or requiring on-site cutting of the vertical plate 22. Controlling the top surface of the vertical plate 22 below the top surface of the embedded part 3 can avoid the risk of interference.

[0039] The adjusting component is an adjusting screw 23, which is mounted on the vertical plate 22 and located on the upper side of the support plate 24. When the screw is rotated, its inner end moves axially, applying a continuous and controllable thrust to the edge of the embedded part 3. Compared with wedges or spring plates, the adjusting screw 23 has a self-locking function, maintaining its position without additional locking components after reaching the set position. The support plate 24 supports the bottom surface of the embedded part 3, and the adjusting screw 23 pushes against it from the side. The two forces act in orthogonal directions, constraining the embedded part 3 both horizontally and vertically, resulting in a stable positioning.

[0040] like Figure 1 As shown, four embedded parts 3 are installed on each of the support frames 1. The four embedded parts 3 are located at the four corners of the support frame 1, and each embedded part 3 is fixed by four fixing clamps 2. The four fixing clamps 2 are distributed around the embedded part 3.

[0041] In substation equipment foundations, multiple embedded parts 3 often need to maintain precise relative positions. For example, in the main transformer foundation, the four legs of the equipment base correspond to four embedded parts 3. A single support frame 1 supports all four embedded parts 3. During factory fabrication, the relative positions of the four embedded parts 3 are determined by the dimensions of the top frame 13 and the installation positions of the fixing clamps 2. On-site measurement of the relative distances between the four embedded parts 3 is no longer necessary; only the overall positioning of the support frame 1 is required to simultaneously complete the coarse positioning of the four embedded parts 3. Each embedded part 3 is pushed from four directions by four fixing clamps 2. The translation of the embedded part 3 in the horizontal plane can be adjusted independently, and the coordinated action of the four clamps can precisely push the embedded part 3 to the design coordinates.

[0042] Example 2 This embodiment provides a construction method for a pre-embedded component 3 support structure that facilitates rapid construction, including the following steps: Place the support frame 1 at the designated position on the concrete pier, so that the bottom frame 11 sits on the pier, and place the embedded part 3 on the fixing clamp 2. Adjust the leveling screws 15 on the bottom frame 11 to adjust the embedded part 3 to a horizontal state, and fix the bottom frame 11 on the support. According to the design elevation of the embedded part 3, adjust the length of the support leg 12 so that the embedded part 3 rises or falls to the set elevation; Rotate the adjusting screw 23 to push the embedded part 3, adjust the embedded part 3 to the preset position, and lock the embedded part 3 on the support seat; Concrete is poured so that the support frame 1 is cast as a whole into the foundation, with part of the embedded part 3 exposed on the foundation.

[0043] During the installation of the embedded part 3, the embedded part 3 is first placed on the support base. The leveling screws 15 on the bottom frame 11 are adjusted to ensure the embedded part 3 is horizontal, and then the bottom frame 11 is fixed. The height of the support legs 12 is adjusted according to the design requirements so that the top surface of the embedded part 3 meets the design requirements. Then, centroid lines are marked on the surface of the embedded part 3 panel and the foundation surface. A plumb line is hung, and the two centroids are aligned by adjusting screws 23. After aligning the center coordinates of the embedded part 3, the adjusting screws 23 are tightened to fix the embedded part 3, ensuring it does not move during pouring. The entire process does not require welding of the embedded part 3, repeated measurement and layout on the top of the support pier, or removal of any temporary supports before pouring. The support frame 1 is not removed after the concrete is poured, which reduces turnover work and avoids disturbing the embedded part 3 when removing the support frame 1.

[0044] While the specific embodiments of the present invention have been described above, they are not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
