Description

Technical Field

[0001] The invention relates to the field of overall movement of buildings, and in particular to an overall translation and relocation device for an ancient building and a construction method thereof. Background Art

[0002] The overall relocation of a building refers to moving the entire building to a preset location. In large-scale construction projects, when encountering buildings that need to be protected, it is inevitable to use the overall relocation technology of the building. The overall relocation of a building is mainly divided into two steps. First, the building is dug at a certain horizontal plane, and then the entire building is towed and moved until the building is moved to the preset location.

[0003] During the excavation of a building, the bottom of the building needs to be supported while the excavation is being carried out. In the prior art, support beams made of steel profiles are generally used to support the building, which has some disadvantages: the excavation of the building is to dig a pit on the ground, cut off the foundation of the building, and after cutting off the preset distance, a support beam needs to be driven in. If the support beam is an integrated structure, the first support beam can easily complete the support. When the following support beam moves into the pit, it needs to move in obliquely. On the one hand, it is inconvenient for the support beam to move in. On the other hand, since the support beam moves in obliquely, the reserved space of the dug pit is The distance between the two adjacent support beams must be much larger than the distance between the two adjacent support beams, otherwise the support beam cannot go in, and the large reserved space means that the bottom of the excavated building cannot be supported in time, and it is easy to cause dangerous accidents such as collapse. If the support beam is assembled, then on the one hand, the connection between the several steel profiles that make up the support beam takes a long time, which delays efficiency. On the other hand, the stability of the connection between the steel profiles needs to be considered, which has higher requirements and greater difficulty. Therefore, it is necessary to improve the excavation support structure of the building. Based on this, the present invention proposes an overall translation and relocation device for ancient buildings and a construction method thereof. Summary of the invention

[0004] In order to solve the problems mentioned in the above background, the present invention provides an overall translation and relocation device for ancient buildings and a construction method thereof.

[0005] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows.

[0006] An overall translation and relocation device for an ancient building comprises a support beam group for supporting the bottom of the building and a support rail group for assisting the support beam group to enter the bottom of the building, wherein the support beam group is provided in several groups and the support rail group is provided in two groups;

[0007] The support beam group includes a main beam and side beam assemblies installed at both ends of the main beam, the side beam assembly includes a side beam that forms a sliding fit with the main beam, and two groups of side beam components are arranged on the side beam, which are a side beam component 1 installed at the end of the side beam and a side beam component 2 located at the side of the side beam component 1 facing the main beam;

[0008] The side beam component comprises an upper beam frame. The upper beam frame of the side beam component 1 is fixedly arranged at the end of the side beam, and the upper beam frame of the side beam component 2 is slidably installed on the side beam.

[0009] As a further improvement and optimization of the present invention, a lower beam frame is slidably installed in the upper beam frame along the vertical direction, a base frame is arranged at the bottom of the lower beam frame, a driving gear is installed at the bottom of the base frame, a hydraulic motor is arranged on the base frame, the hydraulic motor is used to drive the driving gear to rotate, the axis line of the driving gear is parallel to the extension direction of the main beam, and rollers are arranged at both ends of the gear shaft of the driving gear.

[0010] As a further improvement and optimization of the present invention, a second hydraulic cylinder is arranged between the upper beam frame and the lower beam frame, and a first hydraulic cylinder is arranged between the side beam and the upper beam frame of the second side beam component.

[0011] As a further improvement and optimization of the present invention, a synchronization member is arranged between the two groups of side beam assemblies, and the synchronization member includes an intermediate gear arranged at the middle position of the main beam and two side racks respectively arranged on both sides of the intermediate gear, the side racks are meshed with the intermediate gear, the extension direction of the side racks is parallel to the extension direction of the main beam, and the ends of the side racks are connected to the side beams.

[0012] As a further improvement and optimization of the present invention, the support rail group includes a base, three rails are arranged side by side on the base, and a fixed rack is arranged on the upper end surface of the rail. The extension direction of the rail and the fixed rack is parallel to the length direction of the base. The three rails are distributed in an array along the width direction of the base. When the driving gear is engaged with the fixed rack, the rail supports the roller.

[0013] As a further improvement and optimization of the present invention, initially, the distance between two groups of side beam components in the same group of side beam assemblies is smaller than the distance between two adjacent tracks.

[0014] A construction method for an overall translation and relocation device for an ancient building, comprising digging the foundation of the building, wherein the digging process comprises the following steps:

[0015] S1: dig a side groove on each side of the building along the excavation direction, place two sets of support rails in the two side grooves respectively, and the extension direction of the rails is parallel to the excavation direction of the building;

[0016] S2: The foundation of the building is excavated, and the pit formed by the excavation is connected to the side groove. Every time a preset distance is excavated, a support beam group is placed at a preset position through a support rail group to support the building.

[0017] S2 further comprises the following steps:

[0018] S201: The three rails of the support rail group are track one, track two and track three in the direction pointing to the building along the side groove;

[0019] When the preset distance is cut for the first time, the support beam group is moved by pulling the crane, so that the roller of the side beam component 1 is supported by the corresponding track 1, and the roller of the side beam component 2 is supported by the corresponding track 2, and then the hydraulic cylinder 2 is started to drive the side beam and the main beam to move upward to support the building;

[0020] S202: When the preset distance is cut for the second time, the support beam assembly is moved by pulling the crane, so that the roller of the side beam component 2 is supported by the corresponding track 3 and the driving gear is meshed with the fixed rack, and the side beam component 1 is suspended;

[0021] Then, the hydraulic motor of the side beam component 2 is operated to drive the support beam group to move to a preset position on the track 3, and the hydraulic cylinder 1 is started to drive the side beam to extend from the main beam so that the side beam component 1 is located above the track 1;

[0022] Then, the hydraulic cylinder 2 of the side beam component 1 is started, driving the lower beam frame of the side beam component 1 to move downward, so that the roller of the side beam component 1 is supported by the corresponding track 1, and the hydraulic cylinder 2 of the side beam component 2 is started, driving the lower beam frame of the side beam component 2 to move upward, so that the side beam component 2 is suspended;

[0023] Then, the hydraulic cylinder 1 is started to drive the side beam component 2 to move on the side beam, so that the side beam component 2 is located above the track 2, and the hydraulic cylinder 2 of the side beam component 2 is started to drive the lower beam frame of the side beam component 2 to move downward, so that the roller of the side beam component 2 is supported by the corresponding track 2;

[0024] Then, the hydraulic cylinders 2 in the side beam component 1 and the side beam component 2 are started simultaneously, driving the side beam and the main beam to move upward to support the building;

[0025] S203: Repeat S202 until the building is dug up.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. It can realize the support of the building. When the support operation is performed, on the one hand, the support is semi-automatic and does not require workers to assemble on site. The operation is simple and convenient, which reduces the labor intensity of the workers. On the other hand, when the support beam group enters the preset position of the building, there is no need to reserve space. The bottom of the excavated building can be supported in time, and the safety is improved;

[0028] 2. When supporting a building, the distance between two adjacent tracks is L, and the moving distance of the side beam on the main beam is greater than L and less than 2L. The three tracks are set in such a way that the supporting beam group can pass smoothly later, that is, the distance L between two adjacent tracks is slightly greater than twice the thickness of the side beam. In other words, the moving distance of the side beam is small, and most of the side beam is still located on the main beam, that is, the main beam and the side beam can be regarded as an integrated structure, which does not affect the supporting performance of the building;

[0029] 3. In this solution, the movement of the side beam component 1 and the side beam component 2 can be driven by the hydraulic cylinder 1. The advantage of this is that, on the one hand, the structure is simplified, and on the other hand, when the support beam group finally supports the building, since the side beam component 1 is fixedly arranged at the end of the support beam group, the two ends of the support beam group are always supported by the side beam component 1, that is, the two ends of the integrated support beam formed by the main beam and the side beam are always supported, the force is symmetrical, and the support is more stable. It is easy for technical personnel in this field to think of that the side beam component 1 and the side beam component 2 are driven to move on the side beam respectively by two hydraulic cylinders 1, but in this way, when the support is finally achieved, it cannot be guaranteed that the side beam component 1 will eventually be at the end of the integrated support beam, which may easily lead to asymmetric force at both ends of the support beam and affect the stability of the support.

DETAILED DESCRIPTION

[0045] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0046] In the attached drawings of this scheme, a refers to a building and b refers to the foundation of the building.

[0047] In this plan, the main core is the building support during the excavation of the building during the overall translation and relocation of the ancient building. As for the excavation technology and the subsequent building traction and movement technology, they can be realized using existing technologies and will not be elaborated on.

[0048] Reference Figure 1-Figure 13 A device for the overall translation and relocation of an ancient building includes a support beam group 200 for supporting the bottom of the building and a support rail group 100 for assisting the support beam group 200 to enter a preset position at the bottom of the building, wherein the support beam group 200 is provided in several groups and the support rail group 100 is provided in two groups.

[0049] When in use, first dig a side groove on each side of the building, and place two groups of support rail groups 100 in the two side grooves respectively. Then, the foundation of the building is dug, and the pit formed by the digging is connected to the side grooves. Every time a preset distance is dug, a support beam group 200 is placed in a preset position through the two groups of support rail groups 100 to support the building.

[0050] Support rail set 100:

[0051] Reference Figure 7 The support rail group 100 includes a base 101, on which three rails 102 are arranged side by side, and the upper end surface of each rail 102 is provided with a fixed rack 103, wherein the extension direction of the rail 102 and the fixed rack 103 is parallel to the length direction of the base 101, and the three rails 102 are distributed in an array along the width direction of the base 101, and the width of the fixed rack 103 is smaller than the width of the rail 102; when in use, when the support rail group 100 is placed in the side grooves on both sides of the building, the length direction of the base 101 should be parallel to the excavation direction of the subsequent building.

[0052] Support beam set 200:

[0053] Reference Figure 8 and Fig. 9 The support beam group 200 includes a main beam 201 and side beam assemblies 202 installed at both ends of the main beam 201, wherein the side beam assemblies 202 can move along the extension direction of the main beam 201. Preferably, in order to ensure that the distance between the two sets of side beam assemblies 202 is consistent each time they move, refer to Fig. 9 A synchronizer 2011 is arranged between the two groups of side beam assemblies 202. Furthermore, the synchronizer 2011 includes an intermediate gear arranged at the middle position of the main beam 201 and two side racks arranged on both sides of the intermediate gear. The side racks are meshed with the intermediate gear. The extension direction of the side racks is parallel to the extension direction of the main beam 201. The ends of the side racks are connected to the side beam assemblies 202. In this way, the two groups of side beam assemblies 202 can be ensured to move synchronously in different directions and equidistantly.

[0054] Reference Fig.10 and Fig.11 The side beam assembly 202 includes a side beam 203 that is slidably matched with the main beam 201 , and two groups of side beam components 205 are provided at the suspended end of the side beam 203 .

[0055] Reference Fig.12 and Fig.13 The side beam component 205 includes an upper beam frame 206, in which a lower beam frame 207 is slidably installed along the vertical direction. The lower beam frame 207 is driven to move in the upper beam frame 206 by a hydraulic cylinder 208 arranged between the upper beam frame 206 and the lower beam frame 207. A base frame 209 is arranged at the bottom of the lower beam frame 207, and a driving gear 211 is installed at the bottom of the base frame 209. The driving gear 211 and the hydraulic motor 210 arranged on the base frame 209 are connected to each other through a power transmission member 213. The axis of the driving gear 211 is parallel to the extension direction of the main beam 201. Preferably, two driving gears 211 are arranged along the width direction of the main beam 201.

[0056] Rollers 212 are provided at both ends of the gear shaft of the driving gear 211 . When the driving gear 211 is meshed with the fixed rack 103 , the outer circumferential surface of the roller 212 contacts the upper end surface of the track 102 , that is, the roller 212 is supported by the track 102 .

[0057] Reference Fig.10 and Fig.11 In the two groups of side beam components 205, the upper beam frame 206 of one group of side beam components 205 is fixedly set on the end of the side beam 203, and this side beam component 205 is named side beam component one; the upper beam frame 206 of the other group of side beam components 205 is movably installed on the side beam 203 and the sliding direction of this upper beam frame 206 is parallel to the extension direction of the main beam 201, and this side beam component 205 is named side beam component two.

[0058] A hydraulic cylinder 1 204 is provided between the side beam 203 and the upper beam frame 206 of the side beam component 2.

[0059] Initially, the distance between two sets of side beam components 205 in the same set of side beam assemblies 202 is smaller than the distance between two adjacent rails 102 .

[0060] When the support rail assembly 100 is fixed in the side grooves on both sides of the building, the three rails 102 along the side grooves point toward the building in the order of: rail one, rail two, and rail three.

[0061] The process of supporting the bottom of the building by the support beam group 200 is as follows:

[0062] First, the support beam group 200 is pulled and moved by a crane or other existing technology, so that the driving gears 211 of the two sets of side beam components 2 in the support beam group 200 are respectively engaged with the fixed racks 103 on the corresponding track 3, and the rollers 212 are supported by the corresponding track 3, while the rollers 212 of the side beam component 1 are suspended. Figure 3 As shown;

[0063] Then, the hydraulic motor 210 of the side beam component 2 is operated, and the driving gear 211 cooperates with the fixed rack 103 to drive the support beam group 200 to move on the track 102, so that the support beam group 200 passes over the other support beam groups 200 that have completed the supporting operation before, and moves to the preset position. Then, the hydraulic cylinder 1 204 is started. Since the side beam component 2 is connected to the track 3 at this time, and the side beam component 1 is suspended, the side beam 203 can be driven to extend from the main beam 201, and finally the side beam component 1 is located above the corresponding track 1, as shown in FIG. Figure 4 As shown;

[0064] Then, the hydraulic cylinder 208 of the side beam component 1 is started, driving the lower beam frame 207 of the side beam component 1 downward, so that the driving gear 211 of the side beam component 1 is engaged with the fixed rack 103 on the corresponding track 1, and the roller 212 is supported by the corresponding track 1. Then, the hydraulic cylinder 208 of the side beam component 2 is started, driving the lower beam frame 207 of the side beam component 2 upward, so that the driving gear 211 and the roller 212 of the side beam component 2 are moved upward and suspended in the air. Then, the hydraulic cylinder 1 204 is started. Since the side beam component 1 is connected to the track 1 at this time, and the side beam component 2 is suspended in the air, the side beam component 2 can be driven to move on the side beam 203, and finally the side beam component 2 is located above the corresponding track 2, as shown in FIG. Figure 5 As shown;

[0065] Then, the hydraulic cylinder 208 of the side beam component 2 is started, driving the lower beam frame 207 of the side beam component 2 to move downward, so that the driving gear 211 of the side beam component 2 is engaged with the fixed rack 103 on the corresponding track 2, and the roller 212 is supported by the corresponding track 2, such as Figure 6 As shown, at this time, the support beam group 200 reaches the preset position;

[0066] Finally, the hydraulic cylinder 208 in the side beam components 1 and 2 is started synchronously, driving the side beam 203 and the main beam 201 to move upward to support the building.

[0067] In the above process:

[0068] 1. It can realize the support of the building. When the support operation is performed, on the one hand, the support is semi-automatic and does not require workers to assemble on site. The operation is simple and convenient, which reduces the labor intensity of the workers. On the other hand, when the support beam group enters the preset position of the building, there is no need to reserve space. The bottom of the excavated building can be supported in time, and the safety is improved;

[0069] 2. When supporting a building, the distance between two adjacent tracks is L, the movement distance of the side beam is less than 2L and greater than L, and the three tracks are set up to ensure the smooth passage of the supporting beam group behind, that is, the distance between two adjacent tracks is slightly greater than twice the thickness of the side beam. In other words, the movement distance of the side beam is small, and most of the side beam is still located on the main beam, that is, the main beam and the side beam can be regarded as an integrated structure, which does not affect the supporting performance of the building;

[0070] 3. In this solution, the movement of the side beam component 1 and the side beam component 2 can be driven by the hydraulic cylinder 1. The advantage of this is that, on the one hand, the structure is simplified, and on the other hand, when the support beam group finally supports the building, since the side beam component 1 is fixedly arranged at the end of the support beam group, the two ends of the support beam group are always supported by the side beam component 1, that is, the two ends of the integrated support beam formed by the main beam and the side beam are always supported, the force is symmetrical, and the support is more stable. It is easy for technical personnel in this field to think of that the side beam component 1 and the side beam component 2 are driven to move on the side beam respectively by two hydraulic cylinders 1, but in this way, when the support is finally achieved, it cannot be guaranteed that the side beam component 1 will eventually be at the end of the integrated support beam, which may easily lead to asymmetric force at both ends of the support beam and affect the stability of the support.

[0071] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
