Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to a relocation structure for old buildings on the roof slab of a newly constructed basement and a relocation method thereof. Background Technology

[0002] Some historical buildings or valuable old buildings require basement construction on their original sites. Since old buildings cannot be directly demolished and rebuilt, they need to be moved away from their original sites as a whole. After the basement construction is completed at the original site, the buildings are moved back to their original sites. However, during the relocation process, the basement roof has structures such as upturned beams, and there is a height difference on the basement roof, which makes it difficult to move the old buildings back. The traditional construction method is to use jacks to lift the old buildings and then push them back. Although this method can move the old buildings back to their original sites, it places too much vertical load on the basement roof and poses a significant safety hazard. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects of the prior art and provide a relocation structure and relocation method for old buildings on the roof of a newly built basement. This solves the problem of height difference on the roof of a newly built basement and the problem that the roof of the basement cannot bear the sliding load, thereby improving the stability of the relocation.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is an old building relocation structure on the top slab of a newly built basement, including multiple relocation tracks connecting the original site and the temporary storage site of the old building, multiple relocation tracks set on the top slab of the basement and connected to the multiple relocation tracks one by one, multiple pad beams respectively placed between the top slab of the basement and the multiple relocation tracks to make the multiple relocation tracks flush with the corresponding relocation tracks, and a force transmission structure connecting the top slab of the basement and the bottom slab of the basement and facing the multiple pad beams.

[0005] A further improvement of the relocation structure for old buildings on the newly constructed basement roof slab of the present invention is that the force transmission structure includes: a horizontal force transmission beam group, one side of which abuts against the basement roof slab and faces the pad beam, and the other side is connected to the adjacent structural column in the basement structure.

[0006] A further improvement of the relocation structure for old buildings on the roof slab of a newly constructed basement of this invention lies in that the structural columns are arranged in a matrix at intervals in the basement structure, and the arrangement direction of each row of structural columns is the same as the length direction of the pad beams. The horizontal force transmission beam group includes:

[0007] Multiple pairs of column-supporting beams are arranged along the length of the pad beam, and each pair of column-supporting beams is connected to the opposite inner sides of the two longitudinal rows of structural columns.

[0008] Multiple steel main beams are spaced apart along the length of the pad beam, and each steel main beam is supported and connected at both ends to the top of a corresponding pair of column beams;

[0009] A steel distribution beam is connected to the top of a plurality of steel main beams along the length of the pad beam. The steel distribution beam abuts against the basement roof slab and is directly opposite the corresponding pad beam.

[0010] A further improvement of the relocation structure for old buildings on the newly constructed basement roof slab of the present invention is that the force transmission structure includes: multiple steel columns spaced apart along the length of the pad beam, one end of each steel column being supported on the basement floor slab, and the other end being directly opposite the pad beam and abutting against the basement roof slab.

[0011] A further improvement of the relocation structure of the old building on the top slab of the newly built basement of the present invention is that at least four of the multiple pad beams are set in pairs and respectively on the inner and outer sides of the outer wall of the old building, and the top of the four pad beams are connected to the wall clamping beams.

[0012] A method for relocating an old building to its new basement roof slab includes the following steps:

[0013] Step 1: After the basement roof slab is completed, multiple relocation slides are constructed on the basement roof slab, so that the multiple relocation slides correspond one-to-one with the multiple relocation slides. Each relocation slide is connected to a pad beam at the bottom of the basement roof slab, so that each relocation slide is flush with the corresponding relocation slide.

[0014] Step 2: Construct a load-transfer structure at the bottom of the basement roof slab and directly opposite each of the aforementioned pad beams to transfer the load to the basement structural floor slab.

[0015] Step 3: Use the relocation slide and the return slide to push the old building back.

[0016] A further improvement of the method for relocating old buildings on the roof slab of a newly constructed basement in this invention is that, before constructing the pad beam, the reserved opening in the basement structure corresponding to the position to be constructed of the pad beam is temporarily sealed using force-transfer reinforcement.

[0017] A further improvement of the method for relocating old buildings on the roof of a newly constructed basement in this invention is that the structural columns of the basement structure are designed according to the number and location of the supporting columns of the old building. After the old building is relocated, the supporting columns and the structural columns are overlapped and poured accordingly.

[0018] A further improvement of the method for relocating old buildings on the roof slab of a newly constructed basement in this invention is that, before pouring the basement roof slab, the reserved reinforcing bars of the structural columns are extended beyond the designed top elevation of the basement roof slab, and the threaded sleeve is screwed onto the top of the reserved reinforcing bars, so that the height of the threaded sleeve is not higher than the top elevation of the relocation slide; when the supporting column is overlapped with the corresponding structural column, the threaded sleeve is screwed on, so that the threaded sleeve simultaneously connects the reinforcing bars of the supporting column and the reserved reinforcing bars of the structural column at the corresponding position.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. By installing the aforementioned pad beam on the basement roof slab, the height difference of the existing structure on the basement roof slab is smoothed out, which facilitates the stability of the old building during relocation.

[0021] 2. By setting up a force transmission structure, the supporting strength of the basement roof slab was improved, and its load-bearing capacity was enhanced.

[0022] 3. By setting the threaded sleeve, the length of the reserved reinforcing bar can be controlled while ensuring the subsequent lap splicing of reinforcing bars, so as to avoid affecting the relocation of old buildings. Attached Figure Description

[0030] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0031] The following description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed explanation of the relocation structure for old buildings on the roof slab of a newly constructed basement and its relocation method.

[0032] Please see Figures 1-5 As shown, the relocation structure of the old building on the top slab of the newly built basement includes multiple relocation slides connecting the original site and the temporary location of the old building, multiple relocation slides set on the top slab of the basement and connected to the multiple relocation slides one by one, multiple pad beams 2 respectively placed between the top slab of the basement and the multiple relocation slides to make the multiple relocation slides flush with the corresponding relocation slides, and a force transmission structure connecting the top slab of the basement and the bottom slab of the basement and facing the multiple pad beams 2.

[0033] Specifically, when the outer edge of the exterior wall of the old building exceeds the outer edge of the upturned beam of the basement roof slab 1, a cantilevered slab structure is constructed on the outer periphery of the building as the supporting foundation for the exterior wall 16 of the old building during the construction of the upturned beam.

[0034] Specifically, when there is a drainage pipe outlet on the relocation route of the old building, a flip-top concrete cover is connected to the drainage pipe outlet as the foundation for the old building's relocation. After the old building has moved past the concrete cover, the cover is flipped open.

[0035] By installing a flip-top structure at the drain pipe outlet, the relocation of the old building can be ensured without affecting the pre-construction of the drain pipe inside the outlet.

[0036] Preferably, the force transmission structure includes: a horizontal force transmission beam assembly, one side of which abuts against the basement roof slab 1 and faces the pad beam 2, and the other side is connected to the adjacent structural column 3 in the basement structure.

[0037] Preferably, the structural columns 3 are arranged in a matrix at intervals in the basement structure, and the arrangement direction of each row of structural columns 3 is the same as the length direction of the pad beam 2. The horizontal force transmission beam group includes:

[0038] Multiple pairs of column-supporting beams 4 are arranged along the length of the pad beam 2, and each pair of column-supporting beams 4 is connected to the opposite inner sides of the two longitudinal rows of structural columns 3.

[0039] Multiple steel main beams 6 are spaced apart along the length of the pad beam 2, and the two ends of each steel main beam 6 are respectively supported and connected to the top of the corresponding pair of column beams 4;

[0040] A steel distribution beam 7 is connected to the top of a plurality of steel main beams 6 along the length of the pad beam 2. The steel distribution beam 7 abuts against the basement roof slab 1 and is directly opposite the pad beam 2.

[0041] Specifically, when the pad beam 2 is directly opposite a longitudinal row of structural columns 3, the force transmission structure can be omitted, and the sliding load is transferred sequentially from the pad beam 2 to the basement roof slab 1, then to the structural column 3, and finally to the basement floor slab.

[0042] Specifically, when the pad beam 2 is located between the two longitudinal structural columns 3, the horizontal force transmission beam group is adopted to transfer the sliding load sequentially from the pad beam 2 to the basement top slab 1, to the steel distribution beam 7, to the steel main beam 6, to the column-holding beam 4, to the structural column 3, and then to the basement floor slab. The clear force transmission path improves the structural stability.

[0043] Specifically, before constructing the column-supporting beam 4, the structural column 3 is roughened to facilitate the connection stability of the column-supporting beam 4.

[0044] Specifically, the column-supporting beam 4 is anchored to the steel main beam 6. During the construction of the column-supporting beam 4, an anchor plate 5 is pre-embedded on the column-supporting beam 4, and the steel main beam 6 is anchored to the anchor plate 5 during each construction of the column-supporting beam 4.

[0045] Specifically, when there is a gap between the steel distribution beam 7 and the basement roof slab 1, a steel pad of appropriate thickness is inserted into the gap.

[0046] Preferably, the force transmission structure includes: a plurality of steel columns 10 spaced apart along the length of the pad beam 2, one end of each steel column 10 being supported on the basement floor slab, and the other end being directly opposite the pad beam 2 and abutting against the basement roof slab 1.

[0047] Specifically, the bottom end of the steel column 10 is connected to a bottom beam 9 for supporting the basement floor slab, and the top end of the steel column 10 is connected to a supporting steel beam 8 for abutting against the basement roof slab 1.

[0048] Specifically, when the basement structure is a multi-story basement structure, the bottom beam 9 is connected to the top of the bottom slab of the lowest basement structure, the supporting steel beam 8 is connected to the bottom of the top slab of the highest basement structure, and a first steel column is supported between the bottom beam 9 and the structural bottom slab of the upper basement; a second steel column is supported between the supporting steel beam 8 and the top slab 1 of the lower basement; and a third steel column is supported between the top slabs 1 of two adjacent basement levels, with the two ends of the third steel column facing the first steel column and the second steel column respectively.

[0049] When there is no structural column 3 at the bottom of the pad beam 2, the force transmission method of the steel column 10 is adopted to transfer the sliding load from the pad beam 2 to the basement top slab 1, to the supporting steel beam 8, to the steel column 10, to the bottom beam 9, and then to the basement bottom slab.

[0050] Preferably, at least four of the pad beams 2 are set in pairs and respectively on the inner and outer sides of the exterior wall 16 of the old building, and the top of the four pad beams 2 are connected to the wall clamping beam 17.

[0051] Specifically, the bottom of the wall beam 17 is connected at intervals along the length direction with a plurality of sliding feet 18 that slide in cooperation with the relocation slide and the return slide.

[0052] Specifically, in addition to the wall-clamping beam 17, the bottom of the old building is also connected to a tray beam 15, and the bottom of the tray beam 15 is connected to multiple sliding feet 18 at intervals.

[0053] Specifically, after the old building is moved back to its original position, concrete 19 is poured in the space between the two side wall beams 17 and the corresponding two pad beams 2 to connect the old building exterior wall 16 with the basement roof slab 1, combining permanent and temporary structures, and the relocation slide and corresponding sliding foot 18 are also poured inside.

[0054] A method for relocating an old building to its new basement roof slab includes the following steps:

[0055] Step 1: After the construction of the basement roof slab 1 is completed, multiple relocation slides are constructed on the basement roof slab 1 so that the multiple relocation slides correspond to and are connected to the multiple relocation slides. Each relocation slide is connected to a pad beam 2 at the bottom of the basement roof slab 1 so that each relocation slide is flush with the corresponding relocation slide.

[0056] Step 2: Construct a load-transfer structure at the bottom of the basement roof slab 1 and directly opposite each of the pad beams 2 to transfer the load to the basement structural floor slab.

[0057] Step 3: Use the relocation slide and the return slide to push the old building back to its original location.

[0058] A method for jacking up this old building using hydraulic jacks is provided:

[0059] A steel backing 14 was vertically driven into the ground at the rear end of the old building in the direction of relocation.

[0060] The jack 13 is placed between the pallet beam 15 and the steel backing 14 of the old building and connected to the pallet beam 15.

[0061] Using jack 13 to push the steel backing 14, the old building is moved horizontally. After the jack 13 extends to its maximum length, the steel backing 14 is rotated and the above operation is repeated until the old building is moved back to its original position.

[0062] Preferably, before constructing the pad beam 2, the reserved opening in the basement structure corresponding to the location where the pad beam 2 is to be constructed is temporarily sealed using load transfer bars.

[0063] By temporarily sealing the reserved opening at the cross-section of the pad beam 2, the bearing capacity requirement of the pad beam 2 at the reserved opening is ensured, and breakage is avoided.

[0064] Preferably, the structural columns 3 of the basement structure are designed according to the number and location of the supporting columns of the old building. After the old building is moved back to its original location, multiple supporting columns are overlapped with multiple structural columns 3 and poured.

[0065] Specifically, the supporting columns of the old building are arranged in a matrix pattern, and the number of structural columns 3 in the basement structure is no less than the number of supporting columns, and each supporting column corresponds to a supporting column at its bottom.

[0066] Preferably, before pouring the basement roof slab 1, the reserved steel bar 11 of the structural column 3 is extended beyond the design top elevation of the basement roof slab 1, and the threaded sleeve 12 is screwed onto the top of the reserved steel bar 11, so that the height of the threaded sleeve 12 is not higher than the top elevation of the relocation slide; when the support column is overlapped with the corresponding structural column 3, the threaded sleeve 12 is screwed on, so that the threaded sleeve 12 simultaneously connects the steel bar of the support column at the corresponding position and the reserved steel bar 11 of the structural column 3.

[0067] By setting the threaded sleeve 12, the length of the reserved steel bar 11 can be controlled while ensuring that the subsequent support column and the corresponding structural column 3 are connected. This avoids affecting the relocation of the old building.
