Description

Technical Field

[0001] This invention relates to the field of temporary civil engineering structures. More specifically, this invention relates to a method and system for the overall relocation of temporary prefabricated buildings. Background Technology

[0002] Prefabricated steel sheet houses are a new type of environmentally friendly and economical housing, using light steel H-beams and channel steel as the frame, sandwich panels as the wall material, and standardized modular series for spatial combination. Components are connected by bolts or welding. They can be easily and quickly assembled and disassembled, achieving universal standardization for temporary buildings. This establishes an environmentally friendly, energy-saving, fast, and efficient construction concept, bringing temporary housing into a standardized product field characterized by serialized development, integrated production, complete supporting facilities, and the ability to be stocked and reused multiple times.

[0003] However, the actual implementation of prefabricated housing still faces some challenges. Traditional methods for relocating existing corrugated steel sheet prefabricated houses require dismantling, cutting, and preserving standardized components before reassembling them at the destination. This process is not only cumbersome but also prone to damage to interior and exterior decorations, electromechanical systems, and signage. Furthermore, relocating indoor furniture and office equipment incurs additional costs for dismantling and reassembly, wastes relocation time, disrupts nearby traffic, occupies excessive road space, and increases construction costs. Given the current economic downturn, there is an urgent need for cost-saving and revenue-generating measures through technological innovation. Summary of the Invention

[0004] One object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages that will be described later.

[0005] Another objective of this invention is to provide a method and system for the overall relocation of temporary prefabricated houses, in order to solve the technical problems of existing technologies where the relocation equipment for temporary prefabricated houses occupies a large volume and affects the structural stability and transportation efficiency of the prefabricated houses.

[0006] To achieve these objectives and other advantages according to the present invention, in one aspect, the present invention provides a method for the overall relocation of temporary prefabricated houses, comprising the following steps: S1. Set up the prefabricated house structure, which includes columns at the top corners, wall panels covering and connecting adjacent columns, and bottom beams horizontally connecting the bottoms of adjacent columns. Before relocation, drill holes in the lateral shear wall panels connecting the lower ends of each column to form through-holes in the wall panels. S2. Clean and reinforce the columns and bottom beams within the height range of the holes. Fix the corbels to the columns on the side relative to the holes. The corbels have horizontal support structures that extend perpendicular to the wall panel. Install lifting jacks directly below the horizontal supports. The lifting jacks are used to lift the horizontal supports upward to raise the prefabricated house. S3. Use lifting jacks to lift the horizontal brace upwards, so that the bottom beam is off the ground, and install the connecting beam system at the bottom of the bottom beam in the horizontal direction. S4. Use the lifting jacks to continue lifting the horizontal brace upwards, install the track system directly below the beam support system, then retract the lifting jacks so that the beam support system abuts against the track system, and remove the installed lifting jacks. S5. Install a jacking system on the track system. The jacking system is used to push the supporting beam system to slide along the track system, thereby moving the prefabricated house forward. S6. Set up a turning area at the front end of the track system, and install a steering system in the turning area to connect with the track system, so that the prefabricated house can turn in the turning area and complete the position migration of the prefabricated house in the horizontal plane. S7. Install lifting jacks at the hole positions to lift the horizontal bracing, remove the track system and beam support system, retract the lifting jacks to lower the bottom beam to the ground, remove the lifting jacks, cut the corbels, fill and repair the hole positions, and complete the relocation of the prefabricated house.

[0007] Preferably, before moving the prefabricated house in steps S5 and S6, two rows of ground anchors are symmetrically arranged on both sides of the track system along the direction of movement, and two sets of ground anchors are arranged opposite each other on both sides of the steering system along the direction of steering. The ground anchors on the outer side of the track system are positioned 5-10 meters away from the prefabricated house. The spacing between adjacent ground anchors in each row is not less than the distance between the ground anchor and the prefabricated house. The ground anchors in each group are spaced apart along the rotation direction of the prefabricated house, and the distance between each ground anchor in the group and the rotation center of the prefabricated house is less than half the length of the prefabricated house. The ground anchors at the end of the group... The anchor is 5-10 meters away from the prefabricated house at the turning point. Each anchor has a hole at the top center facing downwards. The side wall of the hole has a through hole. The top of the anchor is lower than the bottom of the support beam system. A rope take-up device is inserted through the hole at the top of the anchor. An elastic element is provided at the lower end of the rope take-up device corresponding to the through hole. The elastic element passes through the through hole from the inside of the hole to temporarily fix the rope take-up device. A limiting rope is wound around the rope take-up device. The outer end of the limiting rope is connected to the corresponding side of the prefabricated house. The rope take-up device can adjust the length of the limiting rope released according to the distance from the prefabricated house. Two rows of ground anchors are symmetrically installed on both sides of the prefabricated house. Two sets of ground anchors are driven into the ground opposite each other on the turning path. Rope retractors are installed on the upper end of the ground anchors. The traction limit rope is connected to the corresponding side position of the prefabricated house. As the prefabricated house is transported and the speed is adjusted, the rope retractor controls the extension and retraction of the limit rope. For rope retractors that exceed the length control limit of the limit rope, the connection with the prefabricated house is released, the elastic element is inserted, the rope retractor is removed, and it is reinstalled on the ground anchor on the front side of the prefabricated house's movement path. The corresponding limit rope is then connected to the corresponding side position of the prefabricated house. This operation is repeated until the prefabricated house completes its transport on the track system and its turning on the turning system.

[0008] Preferably, in step S6, after removing the rope retractor, a distance measuring sensor is installed in the insertion hole of the ground anchor located on the path to be rotated and with a horizontal distance of less than 1 meter from the prefabricated house. The distance measuring sensor is connected to a remote control terminal. The distance measuring sensor is used to measure the real-time distance between the prefabricated house and the prefabricated house directly above it when the prefabricated house passes by. The potential tilting risk of the prefabricated house is observed through the real-time distance, and the pushing speed of the steering system is adjusted.

[0009] On the other hand, the present invention also provides a construction system for the overall relocation of temporary prefabricated houses, comprising: The prefabricated house connection structure includes columns set at the top corners, wall panels covering and connecting adjacent columns, and bottom beams horizontally connecting the bottoms of adjacent columns. The lower end of each column is connected to the wall panel with holes in the side through wall panel. The column is connected to a corbel at the hole, and the corbel has a horizontal bracing structure extending perpendicular to the direction of the wall panel. The support beam system is connected to the bottom of the base beam; The track system is set along the moving path of the prefabricated house, and the beam support system slides along the track system; The drive mechanism includes a lifting jack positioned directly below the horizontal brace and a jacking system connected between the track system and the beam support system; The steering system, which is installed at the front end of the track system, acts on the beam support system to drive the prefabricated house to turn.

[0010] Preferably, the columns connecting to the wall panels on three sides are configured as a three-U-shaped channel steel structure, and the columns at other positions are configured as a double-U-shaped channel steel structure. The double-U-shaped channel steel structure is formed by welding two U-shaped channel steels back-to-back or at right angles to each other at the web. The two back-to-back welded U-shaped channel steels are welded together to the outer side of the web of a U-shaped channel steel to form a three-U-shaped channel steel structure. Square timber is inlaid in the slot of each U-shaped channel steel at the hole to reinforce the column.

[0011] Preferably, the bracket includes a vertical support, one end of the horizontal support is welded and fixed to the vertical support, and the other end is welded to the upper end of the vertical support with a diagonal brace. The vertical support is bolted to the square timber and the U-shaped channel steel.

[0012] Preferably, the beam support system includes longitudinal support beams connected to the bottom of the base beam along the length of the prefabricated house, transverse support beams connected between the longitudinal support beams, and scissor braces. The ends of the longitudinal support beams are provided with pin holes, and clamps are provided between adjacent longitudinal support beams. Bolt holes are provided at intervals on the clamps. The connection between adjacent longitudinal support beams is achieved by aligning the bolt holes at both ends of the clamps with the corresponding pin holes and screwing in bolts.

[0013] Preferably, an L-shaped anti-detachment beam is welded downwards on the outer side of the longitudinal support beam, with the lower end of the anti-detachment beam spaced apart from the lower edge of the longitudinal support beam.

[0014] Preferably, the track system includes two rows of sleepers spaced apart on both sides of the prefabricated house along the movement path, with a rail fixed on each row of sleepers along the movement path, a sliding rod fixed on the top of the rail along the movement path, and a support rod connecting the two rails.

[0015] Preferably, the jacking system includes reaction plates symmetrically mounted on the two rails, with the reaction plates temporarily fixed to the rails. A jacking jack is installed between the reaction plates and the longitudinal support beam, and the corresponding end of the jacking jack is connected to the reaction plate via a flexible rope. The longitudinal support beam is jacked forward by the jacking jack.

[0016] The present invention has at least the following beneficial effects: The construction method and system for the overall relocation of temporary prefabricated houses of the present invention includes four stages: prefabricated house reinforcement, setting up a relocation system, prefabricated house transportation, and prefabricated house turning. The relocation construction system includes a prefabricated house connection structure, a beam support system, a track system, a drive mechanism, and a turning system. First, the columns of the prefabricated house body, which serve as the main connecting components, are reinforced, and connecting brackets are installed. A beam support system is welded to the bottom of the prefabricated house for further reinforcement. At the same time, the beam support system serves as the target of the subsequent jacking system. It is transported along the track system by the drive mechanism and the orientation is adjusted by the docking and turning system, which drives the prefabricated house to move and relocate to its position. There is no need to change the original layout and structure of the prefabricated house. The reinforcement of the prefabricated house improves the transportation safety of the prefabricated house, ensures the integrity of the overall structure of the prefabricated house, has little impact on the surrounding environment, does not occupy unrelated sites, does not require additional equipment such as cranes, and the overall relocation progress is fast. All prefabricated houses do not need to be dismantled and reinstalled, and the items inside the prefabricated houses do not need to be moved, which greatly saves time and construction costs.

[0017] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0020] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are all conventional methods, and the reagents and materials described are all commercially available unless otherwise specified.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] like Figures 1-9 As shown, the present invention provides a method for the overall relocation of temporary prefabricated houses, comprising the following steps: S1. The structure of the prefabricated house 1 is set up. The prefabricated house 1 includes a column 2 set at the top corner, a wall panel 3 covering and connecting adjacent columns 2, and a bottom beam 4 horizontally connecting the bottom of adjacent columns 2. Before relocation, holes are drilled in the lateral shear wall panel 3 connected to the lower end of each column 2 to form a hole 5 that penetrates the wall panel 3.

[0022] In this embodiment, the prefabricated house 1 is assumed to be a regular rectangular structure in the horizontal plane. The prefabricated house 1 is divided into multiple compartments by walls formed by multiple wall panels 3. The length direction of the prefabricated house 1 is taken as the longitudinal direction, and the width direction is taken as the transverse direction. The brackets 6 are installed at the lower ends of both sides of the columns 2 of the prefabricated house 1. The sides of the columns 2 are generally set as walls and doors. In order to ensure the normal installation of the beam support system 8, the brackets 6 need to be installed on the columns 2 of the front and rear walls. The installation direction is perpendicular to the length direction of the prefabricated house 1. Therefore, the wall and door parts of the prefabricated house 1 need to be drilled. The specifications of the drilled holes are 0.5m high and 0.12m wide. The width is sufficient to meet the space requirements for the inner reinforcement structure of the columns 2. According to the direction of the columns 2, the measurement and layout are carried out, and a 0.5×0.12m rectangular frame is drawn. It is cut with a toothed saw. Both the inner and outer sides of the wall need to be cut. After completion, the cut wall panels 3 are removed.

[0023] S2. Clean and reinforce the columns 2 and bottom beams 4 within the height range of the hole 5. Remove the wall panels 3 remaining in the columns 2 to ensure that they are clean and free of debris. Fix the corbels 6 to the columns 2 on the side of the hole 5. The corbels 6 and the columns 2 form an integral force-bearing structure. The corbels 6 have a horizontal support 19 structure that extends perpendicular to the direction of the wall panels 3. Install the lifting jacks 7 directly below the horizontal support 19. The lifting jacks 7 are used to lift the horizontal support 19 upward to raise the prefabricated house 1.

[0024] S3. Using jack 7, lift the horizontal support 19 upwards to raise the bottom beam 4 off the ground. Install the connecting beam system 8 horizontally at the bottom of the bottom beam 4. The prefabricated house 1 and the beam system 8 are welded together to bear the load as a whole. The welding is done in a skip-welding manner, with a weld interval of 0.5m, and the weld length does not exceed 5m.

[0025] S4. Using the lifting jack 7, continue to lift the horizontal support 19 upwards. Install the track system 9 directly below the beam support system 8. Then, retract the lifting jack 7 so that the beam support system 8 abuts against the track system 9. Remove the installed lifting jack 7. The beam support system 8 directly contacts the track system 9 and slides on the track system 9.

[0026] S5. Install a jacking system on the track system 9. The jacking system is used to push the beam support system 8 to slide along the track system 9, thereby driving the prefabricated house 1 to move forward along the arranged track.

[0027] S6. Set up a turning area at the front end of the track system 9, and install a steering system in the turning area to connect with the track system 9, so that the prefabricated house 1 can turn in the turning area and complete the position migration of the prefabricated house 1 in the horizontal plane.

[0028] A new turning area is constructed in the relocation area, covering a flat circular or rectangular area with a diameter equal to the length of the prefabricated house 1. The area is located in front of or to one side of the permanent location for easy operation. The prefabricated house 1 is transported to the turning area on the track system 9. All lifting jacks 7 lift the prefabricated house 1, and the support beam system 8 is raised away from the track system 9. Components on the track system 9 that obstruct the installation of the steering system are dismantled. Track guide components 30 corresponding to the steering system are placed under the support beam, such as Φ20 round steel or 05 type small channel steel, with one set every 2-3m, forming a ring according to the direction of rotation to facilitate the rotation force of the prefabricated house 1. Each guide component 30 is coated with lubricating oil to reduce the coefficient of friction. The prefabricated house 1 is rotated around the intersection of the longitudinal and transverse axes until the required rotation position is reached.

[0029] S7. Install lifting jack 7 at hole 5 to lift horizontal support 19, remove track system 9 and beam support system 8, retract lifting jack 7 to let bottom beam 4 fall to the ground, remove lifting jack 7, cut corbel 6, fill and repair hole 5, and complete the relocation of prefabricated house 1.

[0030] The temporary prefabricated house relocation construction method of the present invention includes four stages: reinforcement of the prefabricated house 1, setting up a relocation system, transportation of the prefabricated house 1, and turning of the prefabricated house 1. First, the columns 2 of the prefabricated house 1, which serve as the main connecting components, are reinforced, and connecting brackets 6 are installed to serve as the objects of subsequent jacking by the lifting jacks 7. The bottom of the prefabricated house 1 is welded with a support beam system 8 for further reinforcement. At the same time, the support beam system 8 serves as the object of subsequent jacking system, slides along the track system 9 for transportation, and is adjusted in orientation by connecting with the turning system, thereby moving the prefabricated house 1 as a whole without changing the original layout of the prefabricated house 1. The modular structure helps ensure the overall structural integrity of Prefabricated House 1, minimizes the impact on the surrounding environment, does not occupy unrelated sites, and does not require additional equipment such as cranes. The method of relocating the temporary prefabricated houses as a whole was applied to the continuous beam rotation construction scheme of the overpass of the Shanghai-Kunming Railway in the Pingxiang City Zhonghuan North Road Infrastructure Construction (Sponge City Supporting Project) PPP project. The method allows for the rapid relocation of the adjacent temporary prefabricated houses 1, freeing up space and saving at least fifteen days. All prefabricated houses 1 do not need to be dismantled or reinstalled, and the items inside the prefabricated houses 1 do not need to be moved. The relocation cost is very low, resulting in good economic benefits.

[0031] In another technical solution, such as Figures 10-13As shown, before moving the prefabricated house 1 in steps S5 and S6, two rows of ground anchors 10 are symmetrically arranged on both sides of the track system 9 along the direction of movement. Two sets of ground anchors 10 are arranged opposite each other on both sides of the steering system along the direction of steering. The ground anchors 10 on the outer side of the track system 9 are positioned 15-10 meters away from the prefabricated house 1. The spacing between adjacent ground anchors 10 in each row is not less than the spacing between the ground anchor 10 and the prefabricated house 1. The ground anchors 10 in each group are spaced apart along the rotation direction of the prefabricated house 1, and the distance between each ground anchor 10 in the group and the rotation center of the prefabricated house 1 is less than half the length of the prefabricated house 1. The distance between the end ground anchor 10 in the group and the steering direction is... At the end of the prefabricated house, 15-10 meters away, each ground anchor 10 has a downward-facing insertion hole 11 at the top center. The side wall of the insertion hole 11 is provided with a through hole. The top of the ground anchor 10 is lower than the bottom of the supporting beam system 8. A rope take-up device 12 is inserted into the top of the ground anchor 10 through the insertion hole 11. An elastic element 13 is provided at the lower end of the rope take-up device 12 corresponding to the through hole. The elastic element 13 passes through the through hole 11 from the inside to the through hole to temporarily fix the rope take-up device 12. A limiting rope 14 is wound around the rope take-up device 12. The outer end of the limiting rope 14 is connected to the corresponding side of the prefabricated house 1. The rope take-up device 12 can adjust the length of the limiting rope 14 according to the distance between it and the prefabricated house 1. Two rows of ground anchors 10 are symmetrically installed on the ground on both sides of the prefabricated house 1. Two sets of ground anchors 10 are driven into the ground opposite each other on the turning path. Rope retractors 12 are installed on the upper end of the ground anchors 10. The traction limit rope 14 is connected to the corresponding side position of the prefabricated house 1. As the prefabricated house 1 is transported and the speed increases, the rope retractor 12 controls the winding and unwinding of the limit rope 14. For the rope retractor 12 that exceeds the length control limit of the limit rope 14, the connection with the prefabricated house 1 is released, the elastic element 13 is pressed in, the rope retractor 12 is removed, and it is reinstalled on the ground anchor 10 on the front side of the moving path of the prefabricated house 1. The corresponding limit rope 14 is then connected to the corresponding side position of the prefabricated house 1. The operation is repeated until the prefabricated house 1 completes the transportation on the track system 9 and the turning on the turning system.

[0032] The rope retractor 12 is equipped with a rotary motor, the output shaft of which is connected to a rotating drum. A limiting rope 14 is wound around the rotating drum. The retraction and release of the limiting rope 14 are controlled and temporarily fixed by the rotary motor. It can also be configured as a small winch-like structure, with the same principle. There are many commercially available products, so it will not be described in detail here. The ground anchor 10 can be a rigid structure with a pointed end at the bottom that is driven into the ground, or it can be anchored by drilling a hole in the ground and filling it with concrete.

[0033] Specifically, regarding the installation and utilization of the ground anchors 10, before pushing the prefabricated house 1 in step S5, two rows of ground anchors 10 are symmetrically installed on the ground on both sides of the prefabricated house 1. Rope retractors 12 are installed on the upper end of the ground anchors 10, and the traction limit ropes 14 are connected to the corresponding side positions of the prefabricated house 1. As the prefabricated house 1 is transported and the speed increases, the rope retractors 12 control the retraction and extension of the limit ropes 14. For rope retractors 12 that exceed the length control limit of the limit ropes 14, the connection with the prefabricated house 1 is released, and they are installed in a ground anchor 10 at the front end of the movement path of the prefabricated house 1 to fill the gap. This operation is repeated until the prefabricated house 1 is transported on the track system 9. During the overall movement of the prefabricated house 1 along the track system 9, the limit ropes 14 are led out by the rope retractors 12 on the ground anchors 10 on both sides to connect the prefabricated house 1, which plays a role in stabilizing the prefabricated house 1, preventing it from overturning due to sudden strong winds, and ensuring the safe transport of the prefabricated house 1.

[0034] Before the prefabricated house 1 turns in step S6, two sets of ground anchors 10 are driven into the ground along the turning path. Rope retractors 12 are installed on several ground anchors 10 located on the front side of the turn. The traction limit rope 14 is connected to the prefabricated house 1. The rope retractors 12 are installed in a cyclic forward movement in the manner of step S5, and the rope retractors 12 on both sides of the arc direction are connected to the prefabricated house 1, which plays a role in stabilizing and preventing deviation of the prefabricated house 1 during the turn. The turning system uses the guide member 30, which forms a ring shape with the overall direction, as the bottom track. Jacks are used to push and rotate on the guide member 30, gradually pushing until the prefabricated house 1 is rotated into place.

[0035] In another technical solution, such as Figures 11-12 As shown, in step S6, after removing the rope retractor 12, a distance measuring sensor 15 is installed in the insertion hole 11 of the ground anchor 10 located on the path to be rotated and with a horizontal distance of less than 1 meter from the prefabricated house 1. The distance measuring sensor 15 is connected to a remote control terminal. The distance measuring sensor 15 is used to measure the real-time distance between the prefabricated house 1 and the prefabricated house 1 directly above it when the prefabricated house 1 passes by. The potential tilting risk of the prefabricated house 1 is observed through the real-time distance, and the pushing speed of the steering system is adjusted.

[0036] 106 ground anchors are installed in stages at the front of the rotation. During the rotation, the installation position of the adjacent rope retractor 12 is changed according to the rotation progress. A distance measuring sensor 15 is installed in the insertion hole 11 of the ground anchor 10. The top of the distance measuring sensor 15 is lower than the support beam system 8 to avoid damage to the distance measuring sensor 15. During the rotation of the prefabricated house 1, the distance measuring sensor 15 can measure the distance to the prefabricated house 1 above in real time. The measured distance decreases in segments during the process, corresponding to the support beam system 8 passing directly above the distance measuring sensor 15. If there is a diagonal change in the distance between the distance measuring sensor 15 and the prefabricated house 1, it indicates that the prefabricated house 1 is at risk of tilting. At this time, the jacking direction is stopped and the jacking direction or speed of the jacking jack 29 is adjusted.

[0037] This invention also provides a construction system for the overall relocation of temporary prefabricated houses, such as...Figures 1-11 As shown, it includes: The prefabricated house 1 has a connecting structure, which includes a column 2 set at the top corner, a wall panel 3 covering and connecting adjacent columns 2, and a bottom beam 4 horizontally connecting the bottom of adjacent columns 2. The lower end of each column 2 is connected to the wall panel 3 with a hole 5 through the wall panel 3. The column 2 is connected to a bracket 6 at the hole 5. The bracket 6 has a horizontal brace 19 structure extending perpendicular to the direction of the wall panel 3. Support beam system 8, which is connected to the bottom of bottom beam 4; The track system 9 is set along the moving path of the prefabricated house 1, and the beam support system 8 slides along the track system 9; The drive mechanism includes a lifting jack 7 located directly below the horizontal support 19 and a jacking system connected between the track system 9 and the beam support system 8. The steering system is installed at the front end of the track system 9 and acts on the beam support system 8 to drive the prefabricated house 1 to turn.

[0038] The connection structure of prefabricated house 1 is reinforced by drilling holes on the side of the columns 2 and connecting the brackets 6. These brackets also serve as the position for the subsequent lifting jacks 7. The support beam system 8 is welded to the bottom of the bottom beam 4 to improve the overall connection rigidity of prefabricated house 1. This system also serves as the structure for subsequent jacking, avoiding direct jacking of prefabricated house 1 and affecting its structural safety. Before the overall relocation of prefabricated house 1, a movement path is designed, and a corresponding track system 9 is laid to connect with the steering system. The drive mechanism serves as the power source to jack up prefabricated house 1. The lifting jacks 7 lift the horizontal supports 19, facilitating the installation of the support beam system 8 and track system 9 below the columns 2. After installation, the support beam system 8 slides on the track system 9, ultimately achieving the overall transportation and steering of prefabricated house 1. This has minimal impact on the structure of prefabricated house 1 itself and provides structural reinforcement, which helps ensure the safety of prefabricated house 1 during transportation. At the same time, there is no need to arrange additional large-volume cranes or transportation equipment, resulting in minimal impact on the surrounding environment and significant savings in time and construction costs.

[0039] In another technical solution, such as Figures 1-4 As shown in Figure 6, the column 2 connected to the wall panels 3 on three sides is configured as a three-U-shaped channel steel structure, and the column 2 at other positions is configured as a double-U-shaped channel steel structure. The double-U-shaped channel steel structure is formed by welding two U-shaped channel steels back-to-back or at right angles at the web. The two U-shaped channel steels welded back-to-back are welded together to the outer side of the web of one U-shaped channel steel to form a three-U-shaped channel steel structure. A square timber 16 is inlaid in the slot of each U-shaped channel steel at the hole 5 to reinforce the column 2.

[0040] Two corbels 6 are installed on the double U-shaped channel steel columns 2 of prefabricated house 1. The corbels 6 on the front and rear walls are perpendicular to the longitudinal direction of prefabricated house 1. The gable walls of prefabricated house 1 are perpendicular to the gable walls. There are two installation modes for the corbels 6 on the front and rear walls: one is installation of corbels 6 on the columns 2 in the middle, and the other is installation of corbels 6 on the columns 2 where the front and rear walls intersect with the gable walls. The former uses double U-shaped channel steel columns 2, and the latter uses triple U-shaped channel steel columns 2. The bolt length is selected and adapted according to the structure. The bottom beam 4 is also a U-shaped channel steel, and the inside is reinforced with square timber 16.

[0041] After drilling holes in the walls on both sides and inside the double U-shaped channel steel column 2, the inside of the column 2 is empty. Square timber 16 of the same specification is used to fill and reinforce it. The specifications of the square timber 16 are the same as those of the internal space of the U-shaped channel steel. The square timber 16 is 45×3.5×6.5cm long. Generally, there are two square timber 16 for the double U-shaped channel steel column 2, and three square timber 16 for the triple U-shaped channel steel column 2. The number of square timber 16 can also be determined according to the actual site conditions. When embedding the square timber 16, straighten the rolled edge of the U-shaped channel steel, then embed the square timber 16, and tap the rolled edge to stabilize the square timber 16. At the same time, the square timber 16 is used to connect with the subsequent bracket 6.

[0042] In another technical solution, such as Figure 3 As shown, the corbel 6 includes a vertical support 17, one end of the horizontal support 19 is welded and fixed to the vertical support 17, and the other end is welded to the upper end of the vertical support 17 with a diagonal support 18. The vertical support 17 is bolted to the square timber 16 and the U-shaped channel steel.

[0043] The bracket 6 is composed of vertical support 17, horizontal support 19, and diagonal support 18, which are fabricated and welded together. In the structure, the diagonal support 18 ensures the stability of the structure and is located above the horizontal support 19. Space is left below the horizontal support 19 for the installation and lifting of the jack 7. The vertical support 17 is made of double rows of ∠40×40×3 steel welded together to bear the force, with a length of 0.43m and a 0.01m gap reserved in the middle. The horizontal support 19 is made of ∠40×40×3 steel, also with a certain gap reserved in the middle, and is welded side by side, with a length of 0.147m. The diagonal support 18 is made of ∠25×25×3 angle iron, fabricated and welded together. One end is welded to the side of the vertical support 17, and the other end is welded to the upper side of the horizontal support 19. The bracket 6 and the column 2 form an integral force-bearing structure. The vertical support 17 and the column 2 are connected by bolting.

[0044] In another technical solution, such as Figure 5 , 6As shown in Figure 8, the beam support system 8 includes a longitudinal support beam 20 connected to the bottom of the bottom beam 4 along the length of the prefabricated house 1, a transverse support beam 21 connected between the longitudinal support beams 20, and a scissor brace 22. The ends of the longitudinal support beams 20 are provided with pin holes, and a clamping plate 31 is provided between adjacent longitudinal support beams 20. Bolt holes are provided on the clamping plate 31 at intervals. By connecting the bolt holes at both ends of the clamping plate 31 with the pin holes on the corresponding sides and screwing in bolts, the connection of adjacent longitudinal support beams 20 is realized.

[0045] The supporting beam system 8 is fabricated using the cantilevered I-beams from Building 8. The installation sequence of the supporting beam system 8 is as follows: longitudinal supporting beam 20 I-beams on one side → transverse supporting beam 21 I-beams → horizontal scissor bracing 22 → longitudinal supporting beam 20 I-beams on the other side. All components are bolted together. Since the specifications and dimensions of multiple prefabricated buildings 1 are similar, they can be recycled. The longitudinal supporting beam 20 I-beams are made from a single piece of I-beam. During construction, the raw materials are cut as little as possible to ensure their integrity. The longitudinal supporting beams 20 I-beams are connected by clamps 31. The clamps 31 are 0.32×0.075×0.005 mm long × wide × thick, with bolt holes of Φ12, and a total of 10 clamps are installed.

[0046] One longitudinal support beam 20 starts from one end of the gable wall of the prefabricated house 1. The I-beam of the longitudinal support beam 20 is inserted between the two corbels 6. The front end of the longitudinal support beam 20 is tied with a rope to pull it forward. During the process, care should be taken not to collide with the corbels 6 and the lifting jacks 7. After all the I-beams of the longitudinal support beam 20 are in place, the connecting clamps 31 are connected. The bolts of the clamps 31 can be loosely put on.

[0047] The horizontal support beam 21 (I-beam) and horizontal scissor bracing 22 enter longitudinally from the other side. The horizontal support beam 21 (I-beam) is only provided below the gable wall. Horizontal cross scissor bracing 22 is provided in the rooms at both ends of the prefabricated house 1. The fifth room is also provided with this type of scissor bracing 22. The remaining rooms are only provided with single-sided horizontal scissor bracing 22. After all the components of the support beam are moved into place, the bolts are loosened and tightened. The verticality and whether it corresponds with the position of the prefabricated house 1 are adjusted. If not, it is adjusted to correspond to ensure that the support beam system 8 can fully support the structure of the prefabricated house 1. Finally, all bolts are tightened and the longitudinal support beam 20 is welded to the bottom beam 4. In another technical solution, such as Figures 8-9 As shown, an L-shaped anti-detachment beam 23 is welded downward on the outer side of the longitudinal support beam 20, and the lower end of the anti-detachment beam 23 is spaced apart from the lower edge of the longitudinal support beam 20.

[0048] A derailment prevention device is welded to the outside of the longitudinal support beam's I-beam leg. The device is made of ∠30×30×3 angle iron, which is welded onto the I-beam leg of the longitudinal support beam 20. There is a 1.5cm space between the vertical edge and the I-beam leg, and a total of 3cm of running space on both sides. The device is welded on to prevent derailment during operation. In another technical solution, such as Figures 7-9As shown, the track system 9 includes two rows of sleepers 24 spaced apart on both sides of the prefabricated house 1 along the moving path. Each row of sleepers 24 is fixed with a rail 25 along the moving path. The top of the rail 25 is fixed with a slide bar 26 along the moving path. A support rod 27 connects the two rails 25.

[0049] The transportation of prefabricated houses 1 is similar to that of trains, both running on tracks. The tracks consist of sleepers 24 and cantilevered I-beams of Building 8. Sleepers 24 are located below rails 25, placed perpendicular to the tracks, with one sleeper 24 every 0.5m. The sleepers 24 are connected to the I-beams with steel nails. Most of the steel nails are embedded in the sleepers 24, with the exposed parts pressing against the lower surface of the I-beams. The two rails 25 are connected by bolts with scissor braces or support members, which are processed and welded from ∠40×40×3 angle iron.

[0050] A sliding rod 26 is welded and installed at the centerline of rail 25 to reduce the friction coefficient during transportation and increase the transportation speed. The sliding plate is made of Φ10 round steel. The smaller the contact surface, the lower the friction during sliding. J422 welding rods are sufficient. A skip welding process is used, with a skip length of 0.3m. Welding is carried out symmetrically on both sides. Before transportation, a large amount of lubricating oil is applied to the sliding rod 26 to increase the transportation speed. The track installation process is similar to that of the support beam: one side of the track → scissor brace or strut 27 → the other side of the track.

[0051] In another technical solution, such as Figure 9 As shown, the jacking system includes reaction plates 28 symmetrically mounted on the two steel rails 25. The reaction plates 28 are temporarily fixedly connected to the steel rails 25. A jacking jack 29 is provided between the reaction plates 28 and the longitudinal support beam 20, and the corresponding end of the jacking jack 29 is connected to the longitudinal support beam 20 by a flexible rope. The longitudinal support beam 20 is jacked forward by the jacking jack 29.

[0052] A 1cm thick steel plate is cut into a reaction plate 28, which is then fitted onto the steel rail 25 to bear the force. The force point is in front of the support beam. A jacking jack 29 is installed in the middle, and the two ends are connected to the reaction plate 28 and the longitudinal support beam 20 by steel wire ropes. The positions of the reaction plates 28 on the two steel rails 25 must be synchronized, and the oil supply must also be synchronized. Under the action of the jacking jack 29, the support beam system 8 moves forward, and then the reaction plate 28 is moved forward. The above process is repeated step by step, moving the prefabricated house 1 forward.

They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
