[0002] MiMEP (Multi-trade integrated Mechanical Electrical & Plumbing) is an integrated installation technology that combines mechanical, electrical and plumbing engineering. Its essence is a combination of offline prefabrication and on-site assembly. That is, electrical and mechanical components are manufactured in the factory in advance and then transported to the construction site for assembly, thereby simplifying the on-site installation process and significantly shortening the construction time.

[0033] See also Figures 1 to 4 , Figure 1 A left-side structural schematic diagram of a transport tire frame provided in an embodiment of the present invention; Figure 2 A schematic diagram of the top view of the transport tire frame provided by an embodiment of the present invention; Figure 3 A schematic diagram of the main structure of a transport tire frame provided by an embodiment of the present invention; Figure 4 A schematic flow chart of a construction method for a transport tire frame provided in an embodiment of the present invention.

[0034] See again Figure 1 as well as Figure 3 The transport tire frame provided in the embodiment of the present invention is applied to the transportation of MiMEP, and includes: a frame 100, a plurality of sub-frames 200 and a fixing assembly 300; the frame 100 is formed by vertically stacking the plurality of sub-frames 200; the plurality of sub-frames 200 are connected and fixed by the fixing assembly 300; the inner surfaces of the plurality of sub-frames 200 are vertically fixed with channel steel brackets 210, and the channel steel brackets 210 are used to fix the PC plate channel steel in the MiMEP.

[0035] In this embodiment, a plurality of sub-frames 200 of the same specifications and sizes are stacked and fixed together vertically through the fixing assembly 300 to form a frame 100. The design of vertically stacking the sub-frames 200 makes full use of the vertical space, increases the transport capacity without increasing the floor space of the transport tire frame, and realizes efficient use of space, which is particularly suitable for construction sites or transportation environments with limited space.

[0036] Since the sub-frame 200 is vertically fixed with a channel steel bracket, and the channel steel bracket is used to fix the PC plate channel steel in MiMEP on the sub-frame 200, each layer of the sub-frame 200 that constitutes the frame 100 can fix MiMEP with electrical and pipelines. In actual transportation and construction operations, the MiMEP as a whole specifically includes precast concrete panels, PC plate channel steels, electrical and pipelines. The top of the PC plate channel steel is fixedly connected to the bottom of the precast concrete panel, and the bottom of the PC plate channel steel is fixedly connected to the channel steel bracket. After the electrical and pipelines are fixed to the hanger, the hanger with the electrical and pipelines fixed is connected to the PC plate channel steel. Therefore, each layer of the sub-frame 200 that constitutes the frame 100 can fix the PC plate channel steel with electrical and pipelines, that is, each layer of the sub-frame 200 that constitutes the frame 100 can fix MiMEP to realize the transportation of electrical and pipelines in MiMEP. Each layer of sub-frame 200 can fix PC plate channel steel with electrical and pipelines, so that the transport frame in this embodiment can transport multiple PC plate channel steels with electrical and pipelines (that is, multiple MiMEPs) at the same time. Compared with traditional transportation methods that can only transport a small number of electrical and pipeline components each time, the transport frame in this embodiment greatly increases the transportation volume of a single transportation, reduces the number of transportations, and thus improves the overall transportation efficiency.

[0037] Specifically, it is found through transportation practice that the frame 100 composed of two layers of sub-frames 200 is the best implementation scheme. Therefore, the frame 100 composed of two sub-frames 200 is used as an example for explanation. Assuming that the bottom sub-frame 200 is the first sub-frame, the sub-frame 200 on the first sub-frame is the second sub-frame, and the first sub-frame and the second sub-frame have the same specifications and dimensions, but different positions in the vertical direction. The first sub-frame and the second sub-frame are connected and fixed by a fixing assembly 300, so that the first sub-frame and the second sub-frame form a tight overall structure. During transportation, whether it is subjected to vibration, bumps or other external forces, relative displacement is not easy to occur between the two layers of sub-frames 200, ensuring the stability of the entire frame 100, thereby ensuring the safety of transportation.

[0038] At the same time, when the frame 100 carries PC plate channel steel to transport MiMEP, loads such as vibration and bumps will be transmitted to the bottom through the sub-frame 200. That is, the first sub-frame and the second sub-frame are connected by the fixing assembly 300, which can reasonably distribute and transmit the load between the two layers of sub-frames 200, avoid excessive local force, and improve the bearing capacity of the entire frame 100.

[0039] The length of the frame 100 is the same as the length of the MiMEP, and the length of the frame 100 can be set according to the length of the MiMEP, so that the MiMEP can be set up on the frame 100. The width of the frame 100 is smaller than the width of the transport vehicle (for example, the width of the frame 100 is 2.4 meters) to accommodate MiMEPs of various widths, thereby improving the applicability of the frame 100.

[0040] In one embodiment, if Figure 2 As shown, the sub-frame 200 includes a plurality of first columns 220 and a first beam 230 ; both ends of the first beam 230 are respectively vertically fixed to the plurality of first columns 220 , and are adjacent to the bottom of the first columns 220 .

[0041] In this embodiment, the first columns 220 include a first sub-left column 221, a second sub-left column 222, and a third sub-left column 223 of the same size; the first beam 230 includes a first sub-left beam 231 and a second sub-left beam 232 of the same size. The sub-columns and sub-beams of the same size, as well as their specific welding methods, contribute to the uniform transmission of force in the structure of the sub-frame 200. When a load acts on the sub-frame 200, the force can be evenly dispersed throughout the structure along the welding nodes of the first column 220 and the first beam 230, avoiding stress concentration, thereby improving the overall load-bearing capacity of the sub-frame 200, so that it can transport heavier electrical and pipeline equipment more safely and reliably.

[0042] The sub-frame 200 is composed of a plurality of first columns 220 and a second beam 230, wherein both ends of the first beam 230 are respectively welded and fixed vertically on the first column 220, and the first beam 230 is adjacent to the bottom of the first column 220. The first beam 230 is welded and fixed adjacent to the bottom of the first column 220. This layout can reasonably utilize the space inside the sub-frame 200 while ensuring the structural strength. A suitable space position is provided for fixing the PC plate channel steel with electrical and pipelines on the sub-frame 200, so that the PC plate channel steel can be more conveniently installed on the sub-frame 200, and there will be no waste of space due to unreasonable structural layout, thereby improving the space utilization rate of the sub-frame 200 and facilitating increasing the transportation volume.

[0043] Specifically, one end of the first sub-left cross beam 231 is vertically welded and fixed on the first sub-left column 221, the other end of the first sub-left cross beam 231 is vertically welded and fixed on the first end face of the second sub-left column 222, one end of the second sub-left cross beam 232 is vertically welded and fixed on the second end face of the second sub-left column 222, and the other end of the second sub-left cross beam 232 is vertically welded and fixed on the third sub-left column 223, wherein the first end face of the second sub-left column 222 is opposite to its second end face.

[0044] Since the specifications of the components are uniform, workers can operate more quickly and accurately when assembling the sub-frame 200. Each sub-beam is connected to the sub-column in the same way, and the welding position is relatively fixed, which reduces the uncertainty and error rate in the assembly process, improves the assembly efficiency, shortens the assembly time of the entire transport tire frame, and enables it to be put into use more quickly.

[0045] In one embodiment, if Figure 2 As shown, the sub-frame 200 also includes a plurality of second columns 240 and a second beam 250; both ends of the second beam 250 are respectively vertically fixed to the plurality of second columns 240; the second beam 250 is parallel to the first beam 230 and opposite to it; the second column 240 is parallel to the first column 220 and opposite to it.

[0046] In this embodiment, the plurality of second upright posts 240 include a first right upright post 241, a second right upright post 242, and a third right upright post 243 of the same specifications and sizes; the second cross beam 250 includes a first right cross beam 251 and a second right cross beam 252 of the same specifications and sizes. One end of the first right cross beam 251 is vertically welded and fixed on the first right upright post 241, the other end of the first right cross beam 251 is vertically welded and fixed on the first end face of the second right upright post 242, one end of the second right cross beam 252 is vertically welded and fixed on the second end face of the second right upright post 242, and the other end of the second right cross beam 252 is vertically welded and fixed on the third right upright post 243, wherein the first end face of the second right upright post 242 is opposite to its second end face. The first right upright post, the second right upright post, the third right upright post, the first right cross beam, and the second right cross beam of the same specifications and sizes correspond to and are unified with the specifications of the first upright post and the first cross beam, so as to facilitate batch manufacturing using standardized production processes. This helps improve production efficiency and reduce production costs, while ensuring component quality and dimensional accuracy, ensuring consistent structural performance for each subframe.

[0047] The second column 240 is parallel to and opposite to the first column 220, that is, the first sub-right column 241 is parallel to and opposite to the first sub-left column 221, the second sub-right column 242 is parallel to and opposite to the second sub-left column 222, and the third sub-right column 243 is parallel to and opposite to the third sub-left column 223. The second crossbeam 250 is parallel to and opposite to the first crossbeam 230, that is, the first sub-right crossbeam 251 is parallel to and opposite to the first sub-left crossbeam, and the second sub-right crossbeam 252 is parallel to and opposite to the second sub-left crossbeam. The above parallel and opposite columns and crossbeams form a frame-like structure, which increases the torsional rigidity of the structure. In the process of transporting electrical and pipelines, when encountering torsional forces caused by uneven road surface or other factors, this structure can effectively resist torsion, maintain the shape and integrity of the sub-frame, and avoid damage to the transported electrical and pipelines due to distortion.

[0048] Specifically, Figure 2 as well as Figure 3 As shown, the subframe 200 further includes a plurality of third beams 260 ; both ends of the plurality of third beams 260 are respectively perpendicular to the first column 220 and the second column 240 ; and the third beams 260 are located below the channel steel corbel 210 .

[0049] In this embodiment, the third crossbeam 260 includes a first sub-crossbeam 261 and a second sub-crossbeam 262. One end of the first sub-crossbeam 261 is vertically welded and fixed on the first sub-left column 221, and the other end thereof is vertically welded and fixed on the first sub-right column 241. One end of the second sub-crossbeam 262 is vertically welded and fixed on the third sub-left column 223, and the other end thereof is vertically welded and fixed on the third sub-right column 243. The two ends of the third crossbeam 260 are respectively welded and fixed on the columns on both sides of the sub-frame 200 to form a complete sub-frame 200. When an external load (for example, wind load) acts on the sub-frame 200, the third crossbeam 260, as a component connecting the two sides of the sub-frame 200, can participate in the force transmission and distribution process. It can transfer the load from the first column 220 on one side to the second column 240 on the other side, so that the force is transmitted along the structure of the entire sub-frame 200, and a more reasonable force distribution is achieved. For example, when the electrical appliances and pipelines on the PC plate channel steel are heavy, the downward force generated by their weight will pass through the structural network composed of the first column 220, the second column 240 and the third beam 260, so that the force is evenly dispersed to each first column 220, the second column 240 and the third beam 260, instead of being concentrated on only some components, thereby reducing stress concentration and improving the sub-frame 200's ability to withstand different loads.

[0050] In addition, the third crossbeam 260 can effectively resist lateral forces, such as horizontal impact forces or lateral forces during transportation, and cooperate with other crossbeams (such as the first crossbeam 230 and the second crossbeam 250) and columns (such as the first column 220 and the second column 240) to form a coordinated force system, thereby enhancing the stability of the sub-frame 200 when subjected to forces in different directions, ensuring the reliability of the structure under complex force conditions, and thus improving the safety of electrical and pipeline transportation.

[0051] In one embodiment, if Figure 2 As shown, the channel steel corbel 210 includes a channel steel corbel body 211 and a second through hole 212 ; the second through hole 212 is located at the top of the channel steel corbel body 211 ; the channel steel corbel body 211 is vertically fixed to the first column 220 and the second column 240 .

[0052] In this embodiment, a second through hole 212 is provided on the top of the channel steel corbel body 211. After the second through hole 212 is aligned with the through hole on the PC plate channel steel in the MiMEP, the PC plate channel steel is fixed to the channel steel corbel body 211 through a connecting piece (e.g., a high-strength bolt), thereby fixing the PC plate channel steel with electrical and pipelines to the frame 100, that is, fixing the MiMEP to the frame 100. The second through hole 212 and the through hole on the PC plate channel steel can both be set to an oblong hole shape, which can enhance the applicability of the transport tire frame in the embodiment of the present application on the one hand, and expand the deformation range thereof on the other hand, avoiding the inability of the channel steel corbel body 211 in the transport tire frame to connect with the PC plate channel steel due to a small deformation, thereby reducing the risk that the MiMEP cannot be applied to the transport tire frame. This connection method of the channel steel bracket body 211 and the PC plate channel steel utilizes the high strength and reliability of the bolt connection, ensuring that the PC plate channel steel will not be accidentally displaced or fall off during transportation, storage and installation, thereby ensuring the stability of the entire structure. In addition, compared with other connection methods, the bolt connection has higher shear and tensile strength, and can withstand a certain degree of external force. When encountering bumps and vibrations during transportation, it can effectively prevent the PC plate channel steel from being displaced, providing a reliable structural guarantee for the safe transportation of MiMEP on the frame 100.

[0053] Specifically, the channel steel corbel 210 includes a first channel steel corbel and a second channel steel corbel; the first channel steel corbel and the second channel steel corbel are arranged opposite to each other; the first channel steel corbel is vertically fixed to the first column 220; and the second channel steel corbel is vertically fixed to the second column 240.

[0054] In this embodiment, a channel steel corbel 210 is disposed on each of the first column 220 and the second column 240, wherein the channel steel corbel 210 welded and fixed to the first column 220 is the first channel steel corbel, and the channel steel corbel 210 welded and fixed to the second column 240 is the second channel steel corbel. Since the first column 220 is parallel to and opposite to the second column 240, the first channel steel corbel on the first column 220 and the second channel steel corbel on the second column 240 are facing each other, that is, the first channel steel corbel on the first column 220 and the second channel steel corbel on the second column 240 are not disposed in the same direction.

[0055] The first channel steel bracket and the second channel steel bracket can be made of high-strength structural steel, such as Q345B steel, which has good mechanical properties and a yield strength of up to 345MPa, and can withstand large loads. Considering the mechanical properties of the channel steel bracket 210 when supporting the PC plate channel steel, its thickness can be determined according to the load-bearing requirements. For general MiMEP transportation tasks, the thickness of the channel steel bracket 210 can be around 10-15mm; for the case of carrying heavier electrical and pipelines, the thickness can be increased to 15-20mm to provide sufficient support strength.

[0056] When the channel steel bracket 210 is welded and fixed on the first column 220 and the second column 240, carbon dioxide gas shielded welding or manual arc welding can be used for welding. For carbon dioxide gas shielded welding, the welding current can be set at 180-220A, the voltage is 22-26V, and the welding speed is controlled at 25-30cm / min; for manual arc welding, the welding parameters are adjusted according to the diameter of the electrode and the welding position to ensure that the weld is well formed. During the welding process, the quality of the weld is guaranteed, and the weld is required to be full and continuous, without defects such as pores, slag inclusions, and cracks. After welding is completed, the weld is visually inspected, and the weld excess height, width, and misalignment are measured using a weld inspection ruler to ensure that it meets the design requirements.

[0057] In another embodiment, the connection between the channel steel corbel 210 and the first column 220 and the second column 240 can be bolted, that is, the channel steel corbel 210 is respectively connected to the first column 220 and the second column 240 by bolts. When bolted connection is adopted, high-strength bolts can be used, and other bolts that meet the connection strength requirements can also be used. For MiMEPs of different sizes, the connection interval between the channel steel corbel 210 and the first column 220 and the second column 240 can be changed by changing the spacing and number of bolt holes, so as to adapt to the transportation of MiMEPs of different sizes. For example, for MiMEPs of smaller sizes, a larger spacing and a larger number of bolt holes can be set to extend the connection length of the channel steel corbel 210. After the PC plate channel steel in the MiMEP is fixedly connected to the channel steel corbel 210, the transportation of MiMEPs of smaller sizes can be realized.

[0058] In one embodiment, if Figure 1 as well as Figure 3 As shown, the fixing assembly 300 includes a rib plate 310 and a sleeve 320; the rib plate 310 is vertically fixed to the first column 220 and the second column 240, and is located between the end surface of the channel steel corbel 210 and the third cross beam 260; the sleeve 320 is sleeved on the surface of the joint between the vertically adjacent sub-frames 200.

[0059] In this embodiment, the ratio of the number of ribs 310 to the number of channel steel corbels 210 is 1:1, that is, the two are consistent in number. The ribs 310 are vertically welded and fixed on the first column 220 and the second column 240, and are adjacent to the bottom of the channel steel corbel 210 to support the channel steel corbel 210, thereby reducing the bending deformation of the channel steel corbel 210. When the PC plate channel steel with electrical and pipelines is placed on the channel steel corbel 210, the channel steel corbel 210 will bear a large load and may cause bending deformation. The ribs 310 can effectively share the load borne by the channel steel corbel 210, and transfer part of the pressure to the first column 220 and the second column 240, thereby significantly reducing the bending deformation of the channel steel corbel 210, and ensuring the stability and reliability of the channel steel corbel 210 during use.

[0060] Specifically, the rib plate 310 is vertically welded and fixed on the first sub-left column 221, the second sub-left column 222, the third sub-left column 223, the first sub-right column 241, the second sub-right column 242 and the third sub-right column 243, and the rib plates 310 on the first sub-left column 221, the second sub-left column 222 and the third sub-left column 223 are opposite to the rib plates 310 on the first sub-right column 241, the second sub-right column 242 and the third sub-right column 243. The rib plates 310 on the first sub-left column 221, the second sub-left column 222 and the third sub-left column 223 are adjacent to the lower part of the first channel steel corbel. The rib plates 310 on the first sub-right column 241, the second sub-right column 242 and the third sub-right column 243 are adjacent to the lower part of the second channel steel corbel. In the manufacturing process, the rib plates 310 can be produced and processed according to a unified standard, reducing the production complexity and cost increase caused by inconsistent specifications. During the construction process, construction workers can easily position and weld the rib plates 310 at the corresponding positions according to the positions and installation order of the channel steel corbels 210, which improves construction efficiency and facilitates quality control, ensuring that each channel steel corbel 210 has a corresponding rib plate 310 under it to provide support.

[0061] The sleeve 320 is sleeved on the outer surface of the junction of the vertically adjacent sub-frames to connect and fix the two vertically adjacent sub-frames. This connection method greatly enhances the structural stability of the entire frame 100. During transportation, whether it is subjected to vertical gravity or horizontal impact force (such as inertia generated by bumps, braking, turning, etc. during transportation), it can ensure that there is no relative displacement between the sub-frames 200, thereby ensuring the overall stability of the frame 100 and avoiding the risk of damage to electrical and pipeline components or collapse of the transport tire frame due to looseness between the sub-frames 200. The sleeve 320 is respectively adapted to the first column 220 and the second column 240, so as to be sleeved on the first column 220 and the second column 240 of the two vertically adjacent sub-frames 200, respectively, so as to achieve the fixation of the two vertically adjacent sub-frames 200 to form the frame 100.

[0062] When the sleeve 320 is welded and fixed on the sub-frame 200, the sleeve 320 can be fixed on the vertically adjacent first column 220 and second column 240 by interference fit or welding. For interference fit, the sleeve 320 can be heated or the first column 220 and second column 240 can be cooled according to the interference amount requirement to facilitate installation; for welding, annular welding can be performed at the interface between the sleeve 320 and the first column 220 and the second column 240, and carbon dioxide gas shielded welding or manual arc welding can be used. The welding parameters are adjusted according to the materials and sizes of the sleeve 320 and the first column 220 and the second column 240 to ensure that the welding is firm.

[0063] Both interference fit and welding are highly operable. The interference fit is relatively simple to operate. After heating or cooling, the sleeve 320 can be easily mounted on the first column 220 and the second column 240. Although welding requires certain technical requirements, the welding process is mature. Construction personnel can adjust welding parameters according to the materials and sizes of the sleeve 320, the first column 220 and the second column 240 to ensure a firm weld.

[0064] In addition, during the manufacturing process, the processing of the sleeve 320 is relatively independent, and it can be manufactured according to the sizes of the first column 220 and the second column 240, and then assembled with the first column 220 and the second column 240 that are vertically adjacent to each other through the above-mentioned connection method, which facilitates the mass production and rapid assembly of the transport tire frame and improves the manufacturing and construction efficiency.

[0065] In one embodiment, if Figure 1 As shown, it also includes a plurality of lifting ears 400 ; the plurality of lifting ears 400 are vertically fixed to the outer surface of the sub-frame 200 ; the plurality of lifting ears 400 are located above the channel steel corbel 210 .

[0066] Specifically, the lifting ear 400 includes a lifting ear body 410 and a first through hole 420 ; the first through hole 420 is located in the middle of the lifting ear body 410 ; and the lifting ear body 410 is adjacent to the top of the sub-frame 200 .

[0067] In this embodiment, the lifting lug 400 is used to lift the sub-frame 200. The lifting lug body 410 can be made of high-strength alloy steel, such as Q345B or 40Cr, to ensure that it has sufficient strength and toughness to withstand the tension generated during the lifting process. Taking into account different lifting weights and safety factors, the required load-bearing capacity of the lifting lug is calculated according to the total weight of the frame 100 and the electrical and pipeline equipment it carries, and the size of the lifting lug 400 is determined accordingly.

[0068] The number of the lifting lugs 400 is the same as the number of the channel steel corbels 210, and this number setting ensures uniform distribution of force during lifting. The lifting lugs 400 are opposite to the end faces where the channel steel corbels 210 are located, that is, the lifting lugs 400 are fixed to the outer surface of the sub-frame 200, so as to facilitate smooth lifting and avoid interference between the connectors (such as hooks) on the lifting equipment and the electrical and pipeline equipment on the channel steel corbels 210 during lifting. The lifting lugs 400 are located above the channel steel corbels 210, and the lifting lug body 410 is adjacent to the top of the sub-frame 200, which ensures the stability of the sub-frame 200 during lifting. In addition, setting the lifting lugs 400 above the channel steel corbels 210 that are far away from the electrical and pipeline bearing parts can reduce the impact on the bearing parts during lifting and avoid damage to the electrical and pipeline equipment due to the transfer of force during lifting.

[0069] Before the lifting lug 400 is fixed vertically to the outer surface of the sub-frame 200, the welding part of the lifting lug 400 and the sub-frame 200 is pre-treated. A grinder can be used to remove rust, oil, scale and other impurities from the welding part, so that the welding surface reveals a metallic luster to ensure good welding performance. After welding is completed, when the weld is visually inspected, a weld inspection ruler can be used to measure the weld excess height, width and misalignment to ensure that it meets the design requirements.

[0070] The diameter of the first through hole 420 is determined according to the hook size of the lifting equipment and the connector used (such as a lifting ring, a shackle, etc.). Generally, the diameter of the first through hole 420 is 5-10 mm larger than the diameter of the connector to ensure that the connector can pass through smoothly while avoiding shaking caused by excessive gaps. During the specific construction process, high-precision drilling equipment (such as a CNC drilling machine) can be used to process the first through hole 420 to ensure that the error of its position accuracy is controlled within ±0.5 mm, and to ensure that it is located in the middle of the lifting ear body 410 so that the lifting ear is evenly stressed.

[0071] The first through hole 420 is circular in shape. To ensure the internal surface quality, the hole wall may be bored or reamed to have a surface roughness Ra of no more than 3.2 μm, thereby reducing friction between the connector and the hole wall and preventing damage to the lifting lug 400 due to local stress concentration.

[0072] like Figure 4 As shown, an embodiment of the present invention further provides a construction method of a transport tire frame, which is applied to the transport tire frame in any of the above embodiments, and the method includes:

[0073] S1. Determine the length and width of the sub-frame according to the precast concrete slabs in the MiMEP to be transported.

[0074] In this embodiment, the composition of MiMEP specifically includes precast concrete panels, PC plate channel steels, and electrical and pipelines, wherein the electrical and pipelines are erected and fixed on hangers, and the hangers are set on the PC plate channel steels. The top of the PC plate channel steel is fixed to the lower surface of the precast concrete panels by connecting parts (for example, high-strength bolts). The bottom of the PC plate channel steel is fixed to the channel steel bracket 210 on the inner surface of the frame 100 by connecting parts (for example, high-strength bolts). The frame 100 is hoisted onto the transport vehicle by hoisting equipment to realize the transportation of MiMEP. Therefore, the size of the frame needs to be compatible with the precast concrete panels in MiMEP, avoiding the risk of MiMEP falling during transportation due to the incompatibility of the sizes of the two.

[0075] Specifically, the length of the frame 100 (that is, the length of the sub-frame 200) is determined by accurately measuring the length of the precast concrete slab, and a certain tolerance range is reserved on this basis (for example, a tolerance of ±5 mm is reserved) to ensure that the length of the sub-frame 200 can fully accommodate the precast concrete slab and prevent installation and transportation difficulties due to minor errors. At the same time, according to the measured width of the precast concrete slab, a tolerance range is reserved according to the same principle. The purpose of reserving a certain tolerance range is to reserve a certain space margin for the displacement and shaking that may occur during the transportation of the precast concrete slab, so as to avoid squeezing damage to the precast concrete slab due to shaking during transportation.

[0076] S2. Determine the sizes of the first column, the first beam, the second column and the second beam according to the length of the sub-frame, and determine the size of the third beam according to the width of the sub-frame.

[0077] In this embodiment, since the left side of the sub-frame 200 is obtained by the first column 220 and the first beam 230 being fixed perpendicularly to each other, and the right side of the sub-frame 200 is obtained by the second column 240 and the second beam 250 being fixed perpendicularly to each other, the lengths of the two opposite sides (left side and right side) of the sub-frame 200 determine the sizes of the first column 220, the first beam 230, the second column 240 and the second beam 250. The two ends of the third beam 260 are respectively welded and fixed to the first column 220 and the second column 240 to connect the left side and the right side of the sub-frame 200 to form a complete sub-frame 200, so the width of the sub-frame 200 determines the length of the third beam 260.

[0078] During the transportation of electrical equipment and pipelines, the stability of the frame 100 structure can be ensured by reasonably designing the dimensions of the frame 100, thereby avoiding structural deformation caused by unreasonable dimensions. In addition, accurate dimension design facilitates precise control of the connection parts, thereby ensuring welding quality and improving the load-bearing capacity of the entire frame 100, thereby ensuring the safety of MiMEP during transportation.

[0079] S3, welding and fixing the first column, the first beam, the second column, the second beam and the third beam in sequence to form the sub-frame.

[0080] In this embodiment, the welding part is first pretreated (for example, removing impurities such as rust and oil on the surface) to ensure the cleanliness of the welding surface, thereby improving the welding quality. Secondly, the first column 220, the first beam 230, the second column 240, the second beam 250 and the third beam 260 are positioned and welded and fixed in sequence. For example, the first column 220 and the first beam 230 are first positioned by spot welding to ensure that their verticality and horizontality are within the allowable error range. In addition, the first column 220 and the first beam 230 are welded and fixed by a suitable welding process (for example, carbon dioxide gas shielded welding). Similarly, the second column 240 and the second beam 250, and the welding and fixing between the third beam 260 and the first column 220 and the second column 240 are all carried out in sequence by the aforementioned method. Finally, after the welding is completed, the formed sub-frame 200 is subjected to non-destructive testing, such as ultrasonic flaw detection to check whether there are defects inside the weld.

[0081] For the frame 100 formed by vertically connecting and fixing multiple layers of sub-frames 200, after each layer is welded, the welding quality is checked and then they are connected and fixed together through the rib plate 310. Through pretreatment and precise welding positioning, the welding quality can be improved and the reduction of structural strength due to welding defects can be avoided. In addition, the use of advanced welding technology and detection means can ensure the overall strength and stability of the sub-frame 200, extend the service life, and reduce the later maintenance cost.

[0082] S4. Weld and fix the channel steel corbel and the rib plate to the inner surface of the sub-frame.

[0083] In this embodiment, according to the weight and load-bearing position of the precast concrete slab in MiMEP, the installation position of the channel steel corbel 210 is determined on the inner surface of the sub-frame 200, and the installation point is marked to ensure that the channel steel corbel 210 is evenly distributed and can effectively support the weight of the precast concrete slab.

[0084] For the rib plate 310, according to the stress condition of the sub-frame 200, it is welded under the channel steel corbel 210 to support the channel steel corbel 210 to prevent it from being deformed due to load-bearing. According to the actual construction needs, a suitable welding method is selected to weld and fix the rib plate 310 to the inner surface of the sub-frame 200. For example, intermittent welding or continuous welding is used. By reasonably arranging the channel steel corbel 210 and the rib plate 310, the weight of the precast concrete slab can be effectively dispersed to prevent the sub-frame 200 from being damaged due to excessive local stress.

[0085] In addition, after the components of the sub-frame 200 are welded, the channel steel bracket 210 and the rib plate 310 can be subjected to anti-corrosion treatment, such as coating with anti-corrosion paint. After welding, the fit between the channel steel bracket 210 and the rib plate 310 and the sub-frame 200 is checked to ensure safety and stability during transportation. Anti-corrosion treatment can extend the service life of the sub-frame 200, avoid the decrease in structural strength caused by corrosion, and improve the safety and economy of the entire transport frame.

[0086] S5. Two vertically adjacent sub-frames are fixedly connected by sleeves to form the frame.

[0087] In this embodiment, the inner diameter of the sleeve 320 should match the outer diameter of the first column 220 and the second column 240, so that the first column 220 in the vertically adjacent sub-frame 200 of the same layer and the first column 220 in the sub-frame 200 of the upper layer can be fixed by the sleeve 320. Similarly, the second column 240 in the vertically adjacent sub-frame 200 of the same layer and the second column 240 in the sub-frame 200 of the upper layer can be fixed by the sleeve 320. When installing the sleeve 320, lubricant is applied to the surface of the connection part of the first column 220 and the second column 240 to facilitate the installation of the sleeve 320 and ensure that it can be inserted smoothly. Connecting two vertically adjacent sub-frames 200 by the sleeve 320 can facilitate disassembly and assembly, thereby improving the reusability of the frame.

[0088] For the connection of the multi-layer sub-frame 200, the position of the sleeve 320 at the connection between the first column 220 and the second column 240 in the upper and lower sub-frames 200 is precisely aligned, and positioning pins or auxiliary tools can be used to ensure the concentricity of the connection and prevent structural instability caused by connection deviation. In addition, the sleeve 320 can be fixed with high-strength bolts or pins, and the number and specifications of the bolts or pins are determined according to actual construction needs. The precise installation and fixing method of the sleeve 320 can ensure the stability of the vertical multi-layer sub-frame 200, ensure that the frame 100 will not collapse due to stratification during transportation, and improve the safety of transportation.

[0089] S6. Hoist MiMEP and fix the PC plate channel steel and channel steel bracket in MiMEP.

[0090] In this embodiment, first, before hoisting the MiMEP, check the performance of the hoisting equipment, such as whether the lifting weight, lifting height, working radius, etc. of the crane meet the requirements, and check the hoisting rope to ensure its load-bearing capacity and safety. Secondly, conduct a trial hoisting, lift the MiMEP to a certain height (such as 500mm) from the ground, observe its balance and deformation of the frame, and make timely adjustments if any abnormality occurs. Inspection and trial hoisting before hoisting can avoid safety accidents caused by equipment problems and ensure the safety of the hoisting process. Then, connect the PC plate channel steel in the MiMEP with the channel steel bracket 210 through high-strength bolts, and determine the specifications and tightening torque of the high-strength bolts according to the load-bearing requirements. For example, if M12 bolts are used, the tightening torque is 100N·m. After aligning the bolt hole on the PC plate channel steel with the second through hole 212 on the top of the channel steel bracket 210, the two are connected and fixed by high-strength bolts and high-strength nuts. This precise connection method can ensure the reliable connection between the PC plate channel steel and the channel steel bracket 210, prevent the precast concrete slab from falling off during transportation, and ensure smooth transportation. Finally, after the connection is completed, check the firmness of the connection again, mark and check the connection parts, and ensure that each connection point meets the design requirements.

[0091] The embodiment of the present invention provides a transport frame and a construction method thereof, which are applied to the transportation of MiMEP, and include: a frame 100, a plurality of sub-frames 200, and a fixing assembly 300; the frame 100 is formed by vertically stacking the plurality of sub-frames 200; the plurality of sub-frames 200 are connected and fixed by the fixing assembly 300; the inner surfaces of the plurality of sub-frames 200 are vertically fixed with channel steel brackets 210, and the channel steel brackets 210 are used to fix the PC plate channel steel in the MiMEP. In this embodiment, after the sub-frames 200 are vertically connected and fixed to form the frame 100 by the fixing assembly 300, the MiMEP with electrical and pipelines is fixed on the channel steel brackets 210 of the frame 100, thereby reducing the yard demand while increasing the transportation volume, and reducing the difficulty and cost of transportation.
