Description

Technical Field

[0001] This invention relates to the field of civil engineering technology, specifically to a modular trailer relocation and replacement device and a trailer relocation method. Background Technology

[0002] With the continuous expansion of urban construction and renovation, building relocation technology has developed rapidly and been widely applied. Compared with demolition and reconstruction, building relocation has better social and economic benefits. Traditionally, building relocation uses a combination of rollers and sliders, but this requires a foundation and tracks, making it suitable for short-distance relocations. For long-distance relocations, trailers are often used to support the building, with a reinforced concrete support structure constructed directly beneath the building. This support structure acts as the "chassis" for loading the relocation vehicle, transferring the building's load to the trailer. Simultaneously, the support structure bears the main loads from settlement, deformation, loading, and unloading during the relocation process, ensuring the safety of the superstructure. Therefore, the support structure is a key component in building relocation.

[0003] Typically, support structures are used during building relocation. However, once the building is moved using a trailer, the support structure ceases to function, and the cast-in-place reinforced concrete support structure cannot be reused, resulting in a waste of resources. Chinese Patent (Publication No.: CN103216114B) discloses a method for translating a building, which involves setting up a steel structure support on a raft slab to support the building and achieve jacking and translation. However, the steel support structure, as a supporting structure, does not move with the building but rather bears the pressure during the building's relocation. The stability of the building during relocation still relies on other structures. Furthermore, it only involves vertical height adjustment and does not involve horizontal displacement, making it unsuitable for trailer-based building relocation scenarios and still unable to meet the requirement of being reused after the building is moved by the trailer. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a modular trailer relocation and replacement device and a trailer relocation method. The device uses a steel structure to establish the replacement structure for the relocated building. The entire structure is detachable and effectively ensures the connection strength and load-bearing capacity with the building. It can be repeatedly assembled and reused, reducing project costs, minimizing material waste, and meeting the needs of building relocation.

[0005] The first objective of this invention is to provide a modular trailer relocation and replacement device, which adopts the following solution:

[0006] include:

[0007] Angle steel supports are arranged in pairs; the same pair of angle steel supports are located on both sides of the same frame column and are connected by through bolts that pass through the frame column.

[0008] The clamping column channel steel is arranged in pairs; the same pair of clamping column channel steel is set on both sides of the same row of frame columns, and the clamping column channel steel corresponding to the same frame column supports the angle steel support. The angle steel support is distributed in parallel with the clamping column channel steel.

[0009] The load-bearing steel is located between two adjacent rows of frame columns. The load-bearing steel supports and connects the column-clamping channel steel. The load-bearing steel and the column-clamping channel steel are orthogonally distributed, and the intersection of the load-bearing steel and the same pair of column-clamping channel steel forms a jacking node that receives the jacking action.

[0010] Furthermore, one leg of the angle steel support is attached to the side of the frame column and has a through hole, with a through bolt fitting into the through hole; the other leg of the angle steel support is perpendicular to the side of the frame column it is attached to and abuts against the top surface of the column channel steel.

[0011] Furthermore, both ends of the angle steel support extend to the outside of the frame column, and the upper flange of the column channel steel abuts against and supports the bottom surface of the angle steel support.

[0012] Furthermore, the angle steel supports and column clamping channels are distributed around the corresponding frame columns, with the webs of the same pair of column clamping channels being distributed opposite each other and respectively attached to the side of the frame column. The same pair of column clamping channels are connected at the mid-span and the outer side of the adjacent frame column to clamp the frame column.

[0013] Furthermore, a locking component is provided at the lifting node. The locking component includes a fastener, an upper cover plate located on the top surface of the clamping column channel steel, and a lower cover plate lining the bottom surface of the bearing steel. The fastener connects the upper cover plate and the lower cover plate to lock the relative position of the clamping column channel steel and the bearing steel.

[0014] Furthermore, adjacent pair of interlocking column channel steels and two adjacent load-bearing steel sections together form a rectangular frame. The diagonal positions of the rectangular frame are connected by angle steel bracing. One set of diagonal angle steel bracing is connected above the upper cover plate, and the other set of diagonal angle steel bracing is connected between the upper cover plate and the lower cover plate.

[0015] A second objective of the present invention is to provide a trailer relocation method utilizing the modular trailer relocation and swapping device as described in the first objective, comprising:

[0016] The modular trailer relocation and replacement device is installed on the frame column of the building. Jacks are installed at the lifting node to cut off the frame column from the foundation, and the building load is transferred to the jacks.

[0017] The jacks lift the building, the trailer drives under the load-bearing steel, the jacks retract, and the replacement steel is placed on the trailer;

[0018] The trailer was used to move the building to the new site, and the positions of the frame columns were adjusted to correspond with the foundation of the new site.

[0019] Install jacks at the node locations, lift the building, and then drive the trailer out. After establishing the connection between the frame columns and the new foundation, remove the jacks.

[0020] Furthermore, the jacks lift and retract synchronously, maintaining the stability of the building when its vertical height changes.

[0021] Furthermore, the load-bearing steel sections are distributed perpendicular to the building's displacement direction, and all load-bearing steel sections can be placed on trailers. When the trailer length is insufficient, spliced ​​trailers provide stable support for all steel sections.

[0022] Furthermore, after the building is moved to the new site, the steel reinforcement of the new site's foundation is lapped and welded to the original frame column steel reinforcement, and the frame column body concrete is poured at the connection. After the column body concrete has cured to meet the load-bearing requirements, the jacks are removed.

[0023] Compared with the prior art, the advantages and positive effects of this invention are:

[0024] (1) In view of the problem that concrete support structures cannot be reused and thus lead to waste, steel structures are used to build support structures for relocated buildings. The whole structure is detachable and effectively ensures the connection strength and load-bearing strength with the building. It can be repeatedly assembled and reused, reducing project costs, reducing material waste, and meeting the needs of building relocation.

[0025] (2) By using angle steel supports, the building load can be effectively transferred to the load-bearing steel structure below through the frame columns, through bolts and angle steel supports, establishing a stable force transfer between the frame columns and the supporting structure, improving the stability and safety of the building, and avoiding structural damage or instability during displacement caused by improper load transfer.

[0026] (3) By using angle steel bracing, the connection nodes of the column channel steel and the load-bearing steel can be fixed to form a statically indeterminate structure, which increases the stiffness of the support structure, maintains the relative position of the frame columns, and enables them to better resist deformation during displacement.

[0027] (4) The fasteners between the upper and lower cover plates pass through the drilled holes on the angle steel braces to connect with the braces, thereby improving their overall stress stability. The angle steel braces are distributed on both sides of the upper cover plate, and the angle steel braces in the same rectangular frame form a clearance, maintaining the integrity of the angle steel braces and avoiding the problem of strength reduction caused by the damage at the intersection of the angle steel braces.

[0028] (5) The upper and lower cover plates, together with fasteners, form a locking mechanism to ensure that the jacking joint between the clamping column channel steel and the load-bearing steel is effectively fixed. The friction between the cover plate and the load-bearing steel provides a stable connection, avoiding the risk of loosening or slippage of the joint. The lower cover plate also serves as the force point during jacking, stably transmitting the jacking action to the load-bearing steel and the corresponding clamping column channel steel, ensuring smooth relocation.

Detailed Implementation

[0060] Example 1

[0061] In a typical embodiment of the present invention, such as Figures 1-29 As shown, a modular trailer relocation and replacement device is presented.

[0062] like Figure 18As shown, a modular trailer relocation and replacement device includes angle steel supports 9, clamping column channel steel 11, load-bearing steel 13, locking components, and angle steel diagonal braces. The angle steel supports 9 are arranged in pairs, with two angle steel supports 9 on both sides of the same frame column 5. The clamping column channel steel 11 are also arranged in pairs, with two clamping column channel steel 11 on both sides of the same frame column 5, and the clamping column channel steel 11 is distributed parallel to the angle steel supports 9 to ensure stable contact between the angle steel supports 9 and the clamping column channel steel 11. The angle steel supports 9 are connected by through bolts 10 that penetrate the frame column 5. The clamping column channel steel 11 corresponding to the same frame column 5 supports the angle steel supports 9, and the load-bearing steel 13 supports the clamping column channel steel 11, realizing the transmission of force from the frame column 5 through the angle steel supports 9, the clamping column channel steel 11 to the load-bearing steel 13.

[0063] The load-bearing steel 13 is located between two adjacent rows of frame columns 5. The load-bearing steel 13 supports and connects the column clamping channel steel 11. The load-bearing steel 13 and the column clamping channel steel 11 are orthogonally distributed, and the intersection of the load-bearing steel 13 and the same pair of column clamping channel steel 11 forms a jacking node that receives the jacking action.

[0064] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the angle steel support 9 adopts an angle steel structure. One leg of the angle steel support 9 is drilled with holes and fixed to both sides of the frame column 5 by through bolts 10. The other leg is in a horizontal state and perpendicular to the side of the frame column 5 it is attached to, and is used to abut against the top surface of the clamping column channel steel 11.

[0065] The length of the angle steel support 9 is slightly greater than the width of the column, allowing both ends of the angle steel support 9 to extend beyond the frame column 5, thus extending the contact range between the angle steel support 9 and the supporting column channel steel 11. The upper flange of the supporting column channel steel 11 abuts against and supports one leg of the bottom of the angle steel support 9, and each pair of supporting column channel steels 11 supports the corresponding pair of angle steel supports 9. The function of the angle steel support 9 is to transfer the building load through the frame column 5, the through bolts 10, and the angle steel support 9 to the supporting column channel steel 11 and the load-bearing steel 13 below.

[0066] Specifically, in this embodiment, holes are drilled on two sides of each frame column 5 perpendicular to the displacement direction, penetrating the column body, and through bolts 10 are inserted. There are no fewer than two through bolts 10 on the same frame column 5. The shear bearing capacity of the through bolts 10 is calculated based on the load transmitted by each frame column 5 to determine the bolt cross-sectional area. Angle steel supports 9 are also arranged parallel to the displacement direction, and the through bolts 10 are arranged perpendicular to the orientation of the angle steel supports 9.

[0067] like Figure 7 , Figure 8 and Figure 9As shown, the clamping column channel steel 11 is arranged parallel to the displacement direction, the upper flange of the clamping column channel steel 11 supports the horizontal limb of the angle steel support 9, and the web of the clamping column channel steel 11 is close to the side of the frame column 5.

[0068] Angle steel supports 9 and column clamping channel steels 11 are distributed on the same pair of side positions of the frame column 5. The webs of the same pair of column clamping channel steels 11 are distributed opposite each other and respectively attached to the side of the frame column 5. The same pair of column clamping channel steels 11 are connected at the mid-span and the outer side of the adjacent frame column 5 to clamp the frame column 5.

[0069] Specifically, in this embodiment, clamping channel steel 11 is installed on both sides of each row of frame columns 5, parallel to the displacement direction. The outer side of the web of the channel steel is close to both sides of the frame column 5, and the upper flange of the channel steel is close to the bottom surface of the horizontal leg of the angle steel support 9. Holes are drilled on the webs of the two parallel channel steels on both sides of the frame column 5 parallel to the displacement direction, near the mid-span of adjacent frame columns 5 and at corresponding locations on the outer side of the side columns. Connecting bolts 12 are used to pass through the clamping channel steels, so that the clamping channel steel 11 on both sides of the frame column 5 is tightly fixed to both sides of the frame column 5 to prevent the clamping channel steel 11 from slipping under its own weight.

[0070] like Figure 10 , Figure 11 and Figure 12 As shown, the load-bearing steel 13 is distributed along the direction perpendicular to the displacement, and the upper flange supports the column channel steel 11.

[0071] The load-bearing steel section 13 is located at the mid-span of the frame column 5, parallel to the displacement direction, and approximately 1 meter outside the side column. The upper flange of the load-bearing steel section 13 supports the column-clamping channel steel 11.

[0072] In this embodiment, the load-bearing capacity and deformation of the underpinning structure are calculated based on the load of a common office building or dormitory building with six floors or less, and the cross-sectional dimensions of the clamping column channel steel 11 and the load-bearing steel 13 are selected to increase the versatility of the underpinning structure. The lengths of the clamping column channel steel 11 and the load-bearing steel 13 should preferably be selected from various specifications such as 9m, 6m, 3m and 1.5m to adapt to the length and width requirements of the relocated building.

[0073] Typically, the column clamping channel steel 11 is arranged parallel to the displacement direction, with the length of the column clamping channel steel 11 extending about 2m outward from the outermost side frame column 5 at both ends. The load-bearing steel 13 is arranged perpendicular to the displacement direction, with the length of the load-bearing steel 13 extending about 2m outward from the outermost side column at both ends.

[0074] The load-bearing steel section 13 can be made of H-beams 1 or channel steel. When the length of the load-bearing steel section 13 does not meet the requirements, it can be spliced ​​and extended using H-beams 1 of different lengths. When extending, the webs of two adjacent H-beams 1 are connected by a web connecting plate 2, and the flanges are connected by a flange connecting plate 3. Holes are drilled in the H-beams 1 at the locations where the web connecting plate 2 and the flange connecting plate 3 are installed, and they are fixed with bolts 4.

[0075] Similarly, when the length of the clamping column channel steel 11 does not meet the requirements, channel steels of different lengths can be spliced ​​together to extend it. When extending, the webs of two adjacent channel steels are connected by the web connecting plate 2, and the flanges are connected by the flange connecting plate 3. Holes are drilled in the channel steel at the positions where the web connecting plate 2 and the flange connecting plate 3 are installed, and the channel steel is fixed by bolts 4.

[0076] like Figure 13 , Figure 14 and Figure 15 As shown, a locking component is provided at the lifting node. The locking component includes a fastener 16, an upper cover plate 14 located on the top surface of the clamping column channel steel 11, and a lower cover plate 15 lining the bottom surface of the bearing steel 13. The fastener 16 connects the upper cover plate 14 and the lower cover plate 15 to lock the relative position of the clamping column channel steel 11 and the bearing steel 13. The fastener 16 can be a bolt.

[0077] In this embodiment, an upper cover plate 14, a lower cover plate 15, and four sets of bolts are installed at the connection node between the clamping column channel steel 11 and the bearing channel steel for fixation. The areas of the upper cover plate 14 and the lower cover plate 15 are both larger than the cross-projection area of ​​the clamping column channel steel 11 and the bearing channel steel. Holes are drilled in the four corner areas outside the cross-projection area, bolts and tie rods are installed and tightened, and the lifting node is fixed by the friction of the upper cover plate 14, the lower cover plate 15, and the steel. At the same time, the lower cover plate 15 serves as the force point for the jacks 19 during lifting, loading, and unloading.

[0078] like Figure 16 , Figure 17 and Figure 18 As shown, adjacent clamping column channel steel 11 and two adjacent load-bearing steel sections 13 together form a rectangular frame. The diagonal positions of the rectangular frame are connected by angle steel bracing. One set of diagonal angle steel bracing is connected above the upper cover plate 14, and another set of diagonal angle steel bracing is connected between the upper cover plate 14 and the lower cover plate 15.

[0079] like Figure 19 , Figure 20 and Figure 21 As shown, the angle steel diagonal brace is used to fix the lifting node of the clamping column channel steel 11 and the bearing steel 13, forming a statically indeterminate structure, increasing the stiffness and stability of the support structure, and the jack 19 is applied to the lifting node position.

[0080] The lower elevation of the angle steel support 9 should ensure that after the clamping column channel steel 11, the load-bearing steel 13, and the lower cover plate 15 are installed below, there is enough clearance between the ground and the lower cover plate 15 to install the jack 19. If the clearance cannot be guaranteed due to limitations, the jack 19 can be installed by excavating the ground downwards at the installation location.

[0081] Specifically, angle steel braces are installed between the upper cover plates 14 along adjacent diagonal directions. To prevent collisions between two intersecting angle steel braces, the upper angle steel brace 17 is installed above the upper cover plate 14, with holes drilled in its horizontal limb. The fastener 16 between the upper cover plate 14 and the lower cover plate 15 passes through the drilled holes in the upper angle steel brace 17 to connect with it. The vertical limb of the upper angle steel brace 17 faces upward. The lower angle steel brace 18 is installed below the upper cover plate 14, with holes drilled in its horizontal limb. The fastener 16 between the upper cover plate 14 and the lower cover plate 15 passes through the drilled holes in the lower angle steel brace 18 to connect with it. The vertical limb of the lower angle steel brace 18 faces downward, creating a clearance.

[0082] Adjust the positions of the connecting cover plate, the load-bearing steel 13, and the angle steel bracing to ensure that the bolts between the upper cover plate 14 and the lower cover plate 15 can pass smoothly through the bolt holes. Correct the positions of each component, and finally tighten the nuts on the upper cover plate 14. At this point, the assembled trailer relocation and replacement device is complete.

[0083] like Figures 22-26 As shown, the load-bearing steel sections 13 are distributed perpendicular to the building displacement direction. All load-bearing steel sections 13 can be placed on the trailer. When the trailer length is insufficient, the spliced ​​trailer provides stable support for all steel sections.

[0084] like Figure 27 , Figure 28 and Figure 29 As shown, after the building is moved to the new site, the steel bars of the new foundation 22 are lapped and welded to the steel bars of the original frame column 5, and the concrete of the frame column 5 is poured at the connection. After the concrete of the column body is cured to meet the load-bearing requirements, the jacks 19 are removed.

[0085] Example 2

[0086] In another typical embodiment of the present invention, such as Figures 1-29 As shown, a trailer relocation method using an assembled trailer relocation and replacement device is presented.

[0087] Using the modular trailer relocation and replacement device as described in Example 1, the following steps are included:

[0088] The modular trailer relocation and replacement device is installed on the frame column 5 of the building, and jacks 19 are installed at the lifting node to cut off the frame column 5 from the foundation 7, and the building load is transferred to jacks 19.

[0089] Jack 19 lifts the building, the trailer drives under the load-bearing steel 13, jack 19 retracts, and the replacement steel is placed on the trailer;

[0090] The trailer was used to move the building to the new site, and the position of frame column 5 was adjusted to correspond with the foundation 22 of the new site.

[0091] Install jack 19 at the node location, lift the building and then drive the trailer out. After establishing the connection between the frame column 5 and the new foundation 22, remove jack 19.

[0092] Combination Figures 1-29 The trailer relocation method is described in detail in Example 1.

[0093] ① Lifting and supporting structure

[0094] Directly below each lower cover plate 15, at the intersection of the load-bearing channel steel and the clamping column channel steel 11, screw jacks 19 are installed. First, all the pistons of the jacks 19 press against the lower cover plate 15, cutting off the gap between the frame column 5 and the foundation 7. Then, all the jacks 19 are lifted synchronously, raising the assembled trailer relocation and replacement device and the building connected to it, until the clearance under the assembled trailer relocation and replacement device is slightly higher than the height of the trailer platform 20 of the flatbed trailer.

[0095] ②The trailer drove in

[0096] A flatbed trailer is placed between each adjacent frame column 5, perpendicular to the displacement direction. The trailer drives in along the displacement direction, with its wheel axle 21 perpendicular to the displacement direction. It should be ensured that each load-bearing channel steel can be placed on the flatbed trailer. If the length of the flatbed trailer is insufficient to ensure that each load-bearing channel steel can be placed on it, two or more trailers should be used to extend the trailer before it drives under the assembled trailer displacement and replacement device.

[0097] If the trailer is tall, part of the foundation soil can be excavated to provide space for the flatbed trailer to move.

[0098] ③ Loading

[0099] The piston of jack 19 retracts, and the load-bearing channel steel of the assembled trailer shifting and replacement device is placed on the flatbed trailer.

[0100] ④ Shift

[0101] The flatbed trailer carries the assembled trailer relocation and replacement device and the upper building out of its original location. During the relocation process, the stability of the building's frame beams and slabs is maintained.

[0102] ⑤ In place

[0103] The flatbed trailer, carrying the assembled trailer relocation and replacement device and the superstructure, is driven into the new building site. The building's frame column 5 is aligned with the new site foundation 22 in plan.

[0104] ⑥ Connection

[0105] Directly beneath each cover plate, install screw jacks 19 again. Jacks 19 are simultaneously raised, ensuring the bottom surface of the assembled trailer relocation and replacement device is slightly higher than the top surface of the trailer platform 20, allowing the trailer to drive out from under the building. The reinforcing bars of the new foundation 22 are lapped and welded to the reinforcing bars of the original frame column 5, while simultaneously pouring the new column body concrete 23 at the connection point. Once the column body concrete 23 reaches a certain strength, the piston of jack 19 retracts, and jack 19 is removed.

[0106] In this embodiment, the modular trailer relocation and replacement device is assembled using steel structure components, which are reusable, avoiding the waste caused by the one-time use of reinforced concrete replacement structures and thus reducing costs. The steel structure can be assembled quickly, significantly accelerating construction speed and saving time compared to the concrete curing time of reinforced concrete replacement structures.

[0107] The steel structure components and trailers can be assembled and extended, and the cross-sectional dimensions of the steel structure components are designed for load-bearing capacity based on the common loads of relocated buildings. Therefore, this modular trailer relocation and replacement device can be adapted to frame structure buildings with different spans, different numbers of spans, and common numbers of stories, increasing the applicability of the modular trailer relocation and replacement device and facilitating its turnover.

[0108] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
