Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a building support lifting device and a lifting method thereof. Background Art

[0002] Old buildings have a long history and their walls are severely weathered, which makes them prone to tilting or collapse. Therefore, when repairing and reinforcing historical walls, support devices are needed to protect and assist in fixing the walls to prevent further damage to the walls during the repair process.

[0003] Since the wall itself is fixed by multiple layers of floor slabs, the construction process of the existing support device is to first drill holes on the floor slabs of each layer using drilling equipment, and then use a large crane to hang the steel pipe piles from top to bottom, passing through each layer of floor slabs at one time, and trusses are used between the steel pipe piles of each layer and the walls of each layer to form a support force system.

[0004] However, this construction method often requires renting a large crane to lift the steel pipe piles to assist in construction, which will increase construction costs. Summary of the invention

[0005] In order to solve the problem of increased construction costs caused by placing from top to bottom using a large crane, in a first aspect, the present application provides a building support jacking device.

[0006] The present application provides a building support jacking device that adopts the following technical solution:

[0007] It includes a support frame, a support member, a lifting assembly, a lower end clamping assembly, an upper end clamping assembly and a guide sleeve. A table is provided on the support frame. The guide sleeve is vertically installed on the table. A buffer for buffering the descending speed of the support member is provided at the end of the guide sleeve away from the table. The support member is inserted into the guide sleeve. The lifting assembly is also installed on the table. The lower end clamping assembly is arranged on the lifting assembly for clamping or loosening the support member. A support rod is arranged on the upper end clamping assembly. The support rod is connected to the table. The upper end clamping assembly is also used to clamp or loosen the support member. When the lower end clamping assembly clamps the support member, the upper end clamping assembly loosens the support member. When the lower end clamping assembly loosens the support member, the upper end clamping assembly clamps the support member.

[0008] By adopting the above technical solution, during construction, the support base is fixed at the construction site, and then the support member is inserted into the guide sleeve from below the support base, and the lower clamping assembly clamps the support member. Subsequently, the lifting assembly is activated. After the lower clamping assembly sends the end of the support member into the clamping range of the upper clamping assembly, the lower clamping assembly releases the clamping of the support member. At this time, the buffer member buffers the descending speed of the support member, so that the support member will not descend rapidly after losing the clamping of the lower clamping assembly. At the same time, the upper clamping assembly clamps the support member simultaneously after the lower clamping assembly loses the clamping of the support member. By repeating this process, the lifting of the support member is realized, and thus the support member can be gradually lifted from the lower floor to the higher floor. When the length of the current support member is insufficient, the support members can be continuously lifted by adding the next support member below the support frame. During the whole process, there is no need for a large crane to place the support member from top to bottom, achieving the effect of saving economic costs.

[0009] Optionally, the buffer member includes a collar. The collar is connected to the guide sleeve by a threaded fit. The inner wall of the collar is provided with buffer flaps. The buffer flaps are axially distributed on the inner wall of the collar. The distance between the buffer flap and the inner wall of the collar gradually increases from the direction close to the guide sleeve to the direction away from the guide sleeve. One end of the buffer flap is fixedly connected to the inner wall of the collar, and the other end of the buffer flap is used to abut against the outer wall of the support member.

[0010] By adopting the above technical solution, buffer flaps are provided on the inner wall of the collar, and the distance between the buffer flap and the inner wall of the collar gradually increases from the direction close to the guide sleeve to the direction away from the guide sleeve. This makes it that when the support member enters the collar from bottom to top, the buffer flap does not pose a great hindrance to the upward movement of the support member. However, when neither the upper clamping assembly nor the lower clamping assembly clamps the support member, the downward movement of the support member under its own gravity will be hindered by the buffer flap, thus playing a role in delaying the descending speed of the support member.

[0011] Optionally, the lifting assembly includes two mounting plates and two lifting members. The two lifting members are symmetrically distributed with respect to the axis of the guide sleeve. The lifting members are mounted on the platen. The two mounting plates are respectively mounted on the two lifting members. The lower clamping assembly includes two pushing members and two clamping plates. The two pushing members are respectively mounted on the sides of the two mounting plates away from the lifting members. The two clamping plates are respectively connected to the two pushing members. The two pushing members are respectively used to drive the two clamping plates to clamp or release the support member.

[0012] By adopting the above technical solution, when the two pushing members push the clamping plates to move towards the support member in the guide sleeve until the two clamping plates abut against the outer wall of the support member, a clamping space for the support member is formed between the two clamping plates. After the clamping plates clamp the support member, the lifting of the support member in the guide sleeve can be realized by lifting and lowering the mounting plate by the lifting member.

[0013] Optionally, the upper clamping assembly includes a fixing plate, two fixing blocks and two driving rods. There are at least two supporting rods, which are symmetrically distributed with respect to the axis of the guiding sleeve. One end of each supporting rod is connected to the table board and the other end is connected to the fixing plate. A through hole coaxial with the guiding sleeve is provided on the fixing plate. Both fixing blocks are slidably connected to the side of the fixing plate away from the supporting rods and are symmetrically distributed on the fixing plate with respect to the axis of the guiding sleeve. One end of each of the two driving rods is connected to the sliding block, and the other end of each driving rod passes through the fixing plate and is connected to the clamping plate. The driving rods are used to make the sliding direction of the fixing blocks on the fixing plate opposite to the moving direction of the clamping plate.

[0014] By adopting the above technical solution, a through hole coaxial with the guiding sleeve is provided on the fixing plate, so that the support member can continue to rise through the through hole during the rising process. The driving rods are used to make the sliding direction of the fixing blocks on the fixing plate opposite to that of the clamping plate, so that when the clamping plate needs to descend during resetting, the fixing blocks can fix the height that the support member has been lifted.

[0015] Optionally, a waist-shaped groove with an extending direction consistent with the length direction of the driving rod is provided at one end of the driving rod. The other end of the driving rod is hinged to the clamping plate. An opening groove is provided on the fixing plate, and a rotating rod is provided in the opening groove. The rotating rod passes through the waist-shaped groove, and the driving rod can rotate around the axis of the rotating rod. The fixing block is hinged to the driving rod through the waist-shaped groove.

[0016] By adopting the above technical solution, when the clamping plate approaches the support member under the push of the pusher, the driving rod drives the fixing plate to move away from the support member, and the rotating rod acts as a rotating shaft for the rotation of the driving rod on the fixing plate.

[0017] Optionally, the driving rod includes a first telescopic rod and a second telescopic rod. One end of the first telescopic rod is hinged to the fixing block, the other end of the first telescopic rod is in plug-in fit with one end of the second telescopic rod, the second telescopic rod can slide along the length direction of the first telescopic rod, and the end of the second telescopic rod away from the first telescopic rod is hinged to the clamping plate.

[0018] By adopting the above technical solution, the driving rod includes a first telescopic rod and a second telescopic rod, so that when the pusher descends under the action of the lifting member, the second telescopic rod can extend from the first telescopic rod, and thus the driving rod can be applicable to the rising or falling of the pusher.

[0019] Optionally, a groove with an extending direction consistent with the length direction of the second telescopic rod is provided on the side wall of the second telescopic rod, and a limiting member is provided on the side wall of the first telescopic rod corresponding to the groove. When the second telescopic rod is in plug-in fit with the first telescopic rod, the limiting member passes through the side wall of the first telescopic rod and is located in the groove.

[0020] By adopting the above technical solution, a groove is provided on the side wall of the telescopic rod 2, and the extension direction is consistent with the length direction of the telescopic rod 2, and a limiting piece is provided on the side wall of the telescopic rod 1 at the position corresponding to the groove. The limiting piece passes through the outer wall of the telescopic rod 1 and is located in the groove, so that the telescopic rod 2 will not easily fall off the telescopic rod 1.

[0021] Optionally, the clamping plate includes a clamping portion and a connecting portion, the clamping portion is connected to the pushing member, and two parallel support blocks are provided on the mounting plate. The two support blocks are respectively located on both sides of the pushing member and are parallel to the pushing direction of the pushing member. A limiting portion is provided on the support block, and a limiting groove is provided on the connecting portion, and the limiting portion and the limiting groove are slidably matched.

[0022] By adopting the above technical solution, the connecting part of the clamping plates of the two support blocks can be supported, and at the same time, the sliding cooperation between the limiting groove and the limiting part enables the connecting part on the support block to move only with the movement of the pushing member, so that when the pushing plate is pulled upward or squeezed downward by the second telescopic rod, the pushing direction of the pushing member will not be affected.

[0023] In a second aspect, the present application further provides a jacking method of a building jacking device, using the above-mentioned building support jacking device, comprising the following steps:

[0024] S100: fix the support frame on one side of the building, and put the support member into the guide sleeve from the bottom of the support frame, and the lower clamping assembly clamps the support member, and the upper clamping assembly is in a loose state;

[0025] S200: the lifting assembly drives the lower clamping assembly to rise, thereby driving the support member to rise, driving the lower clamping assembly to release the support member, and at this time, the upper clamping assembly plays a clamping role on the support member;

[0026] S300: After the lifting assembly drives the lower clamping assembly to descend, the lower clamping assembly clamps the support member again, and at this time, the upper clamping assembly is in a release state from the support member;

[0027] S400: Repeat steps S200 and S300 until the support member rises to a designated position.

[0028] In this construction method, the upper clamping assembly and the lower clamping assembly alternately clamp the support members and the jacking assembly is lifted successively, so that the support members pass through the floor slab layer by layer from bottom to top, and the drilling and breaking of the floor slab is also carried out layer by layer. While the drilling and breaking of the upper floor slab is being carried out, the support piles have already passed through the lower floor slab, and the lower floor slab is supported, which improves the supporting force of the floor slab, thereby increasing the supporting strength of the building and achieving the effect of improving its stability.

[0029] In summary, the present application includes at least the following beneficial technical effects:

[0030] 1. The jacking of the support member is achieved through the jacking assembly, the upper clamping assembly, and the lower clamping assembly, so that the support member can be gradually lifted from the lower floor to the upper floor. When the length of the current support member is insufficient, the next support member can be added below the support frame to enable each support member to continue to rise. In the whole process, there is no need for a large crane to place the support member from top to bottom, achieving the effect of saving economic costs.

[0031] 2. By setting the driving rod as the first telescopic rod and the second telescopic rod that can be telescoped on the first telescopic rod, when the jacking assembly drives the pushing member to rise or fall, the length of the driving rod can be changed according to the height of the pushing member.

[0032] 3. Through the alternating clamping of the support member by the upper clamping assembly and the lower clamping assembly and the successive jacking of the jacking assembly, the support member passes through the floor slab layer by layer from bottom to top. Thus, the drilling and breaking of the floor slab are also carried out layer by layer. While the upper floor slab is being drilled and broken, the support pile has passed through the lower floor slab, and the lower floor slab has support, improving the support force of the floor slab, thereby increasing the support strength of the building and achieving the effect of improving its stability.

Detailed implementation manners

[0040] The following further elaborates on this application in conjunction with the attached Figures 1-6 drawings.

[0041] Embodiment 1:

[0042] Embodiment 1 of this application discloses a building jacking device. Referring to Figure 1 and Figure 2 , it includes a support frame 1, a support member 2, a jacking assembly 3, a lower clamping assembly 4, an upper clamping assembly 5, and a guide sleeve 6. A platen 7 is provided on the support frame 1, and the guide sleeve 6 is vertically installed on the platen 7. The support member 2 is a steel pipe pile, and the steel pipe pile passes through the platen 7 from below the support frame 1 and is inserted into the guide sleeve 6. The inner diameter of the guide sleeve 6 is adapted to the outer diameter of the steel pipe pile, so that the error between the axis position of the support member 2 and the axis position of the guide sleeve 6 is within the allowable range when the support member 2 is located in the guide sleeve 6.

[0043] Referring to Figure 3 and Figure 4 , during the rising process of the support member 2, a drill bit with its own power supply and drive can be provided at the upper end of the support member 2, so that the floor slab can be demolished during the rising process of the support member 2. Subsequently, other support members 2 can still be added to the lower end of the support member 2 by means of threaded cooperation, so that the support member 2 can adapt to different heights.

[0044] Referring to Figure 2 , Figure 3 and Figure 4, the lifting assembly 3 includes two lifting members 10 and two mounting plates 9. The lifting members 10 are hydraulic cylinders. The lifting members 10 are mounted on the platen 7 and are symmetrically distributed on both sides of the guide sleeve 6 with respect to the axis of the guide sleeve 6. The two mounting plates 9 are respectively mounted on the movable ends of the lifting members 10. The lower clamping assembly 4 includes two pushing members 11 and two clamping plates 12. The pushing members 11 can be cylinders or electric push rods. The two pushing members 11 are respectively mounted on the side of the two mounting plates 9 away from the lifting members 10. The two clamping plates 12 are respectively mounted on the two pushing members 11. The two clamping plates 12 clamp and release the support member 2 under the pushing of the two pushing members 11 respectively.

[0045] The upper clamping assembly 5 includes a support rod 8, a fixing plate 13, a fixing block 14 and a driving rod 15. The number of the driving rods 15 is the same as the number of the fixing blocks 14. There are two support rods 8 which are both vertically connected to the platen 7. The ends of the two support rods 8 away from the platen 7 are connected to the fixing plate 13. A through hole coaxial with the guide sleeve 6 is provided on the fixing plate 13. The diameter of the through hole is slightly larger than the outer diameter of the support member 2. This enables the support member 2 to smoothly extend out from the through hole under the lifting of the lifting member 10 after being clamped by the two clamping plates 12.

[0046] The two fixing blocks 14 are respectively slidably arranged on both sides of the through hole. The two fixing blocks 14 are symmetrically distributed on the fixing plate 13 with respect to the axis of the through hole. The two driving rods 15 are respectively connected to the two fixing blocks 14. The other ends of the two driving rods 15 pass through the fixing plate 13 and are connected to the clamping plates 12. When the two clamping plates 12 are in a clamping state with respect to the support member 2 and the fixing blocks 14 are in a loosening state with respect to the support member 2, a Z shape is formed among the fixing block 14, the driving rod 15 and the clamping plate 12 on the same side of the guide sleeve 6. The fixing block 14, the driving rod 15 and the clamping plate 12 on the other side of the guide sleeve 6 are mirror symmetric with the fixing block 14, the driving rod 15 and the clamping plate 12 forming the Z shape with respect to the axis of the guide sleeve 6.

[0047] An opening slot 17 for the driving rod 15 to pass through is provided on the fixing plate 13. A rotating rod 18 is arranged in the opening slot 17. The driving rod 15 includes a first telescopic rod 19 and a second telescopic rod 20. A waist-shaped slot 16 with an extending direction consistent with the length direction of the first telescopic rod 19 is arranged at one end of the first telescopic rod 19. The other end of the first telescopic rod 19 is sleeved on the second telescopic rod 20. The second telescopic rod 20 is in plug-in fit with the first telescopic rod 19 and can slide on the first telescopic rod 19. Thus, when the lifting member 10 descends, the second telescopic rod 20 can extend from the first telescopic rod 19. In addition, a U-shaped groove adapted to the outer diameter of the rotating rod 18 is arranged at one end of the second telescopic rod 20 located inside the first telescopic rod 19. This enables more parts of the second telescopic rod 20 to slide inside the first telescopic rod 19 when the lifting member 10 ascends, increasing the range of the telescopic length between the first telescopic rod 19 and the second telescopic rod 20.

[0048] When the clamping plate 12 is in a loosened state for the support member 1 and the fixing block 14 clamps the support member 2, the driving rod 15 is in a vertical state perpendicular to the ground. Then, when the clamping plate 12 descends under the action of the lifting member 10, the second telescopic rod 20 can simply extend from the first telescopic rod 19, and at this time, the position of the fixing block 14 will not change.

[0049] Refer to Figure 3 、 Figure 4 and Figure 5 On the side of the second telescopic rod 20 where the U-shaped groove is not provided, a groove 21 with an extending direction consistent with the length direction of the second telescopic rod 20 is arranged. A limiting member 22 is inserted through the side wall of the first telescopic rod 19 corresponding to the groove 21. The limiting member 22 can be an ordinary bolt or a pin. One end of the limiting member 22 inserted into the first telescopic rod 19 is located in the groove 21, thereby restricting the sliding distance of the second telescopic rod 20 inside the first telescopic rod 19. At the same time, one end of the limiting member 22 being located in the groove 21 also prevents the second telescopic rod 20 from easily disengaging from the first telescopic rod 19.

[0050] Refer to Figure 3 、 Figure 4 and Figure 6, Further, the clamping plate 12 includes a clamping portion 23 and a connecting portion 24. The clamping portion 23 and the connecting portion 24 are fixedly connected to form an L shape. The clamping portion 23 is connected to the movable end of the pushing member 11, and the connecting portion 24 is located above the pushing member 11. In order to prevent the situation that during the rising process of the jacking member 10, the clamping plate 12 is subjected to the vertically upward traction force from the second telescopic rod 20 and during the descending process of the jacking member 10, the clamping plate 12 is subjected to the vertically downward force from the second telescopic rod 20, resulting in the deformation of the movable end of the pushing member 11, a support block 25 is respectively arranged on both sides of the pushing member 11. One side in the length direction of the support block 25 is vertically fixed on the mounting plate 9, and the other side in the length direction of the support block 25 is slidably matched with the lower surface of the connecting portion 24. A limiting groove 26 with an extending direction consistent with the length direction of the connecting portion 24 is arranged on the lower surface of the connecting portion 24. The limiting groove 26 can be a C-shaped groove or a dovetail groove, and a limiting portion 27 slidably matched with the limiting groove 26 is arranged on the support block 25. So that whether the connecting portion 24 is subjected to the upward or downward force from the second telescopic rod 20, the connecting portion 24 always maintains a connection with the support block 25, thereby keeping the connecting portion 24 in a horizontal state all the time.

[0051] Referring to Figure 3 , and in order to prevent the two clamping plates 12 and the two clamping blocks from descending due to their own weights when the support member 2 is in a suspended state during the moving process, a buffer member is arranged at the end of the guide sleeve 6 far away from the table plate 7. The buffer member includes a collar 28, and the collar 28 is connected to the guide sleeve 6 by a threaded fit. A plurality of groups of buffer petals 29 are arranged at intervals along the length direction of the collar 28 on the inner wall of the collar 28. Each group of buffer petals 29 is circumferentially distributed along the inner wall of the collar 28 in the collar 28. The buffer petals 29 are made of rubber, and the distance between the buffer petals 29 and the inner wall of the collar 28 gradually increases from the direction close to the guide sleeve 6 to the direction far away from the guide sleeve 6. This makes the friction force smaller when the support member 2 enters the guide sleeve 6 and the collar 28 from below the support frame 1, so that the support member 2 can smoothly rise under the clamping of the clamping plate 12. When the support member 2 descends due to its own weight, the buffer petals 29 play a role in increasing the friction on the outer wall of the support member 2 to slow down the descending speed of the support member 2.

[0052] The implementation principle of the embodiment of the present application is: first, the support member 2 is inserted into the guide sleeve 6 and the ring 28 from the bottom of the support frame 1 in sequence, so that the two clamping plates 12 can clamp the support member 2 at this time, and the lifting member 10 is started. The lifting member 10 lifts the clamping plate 12 to drive the support member 2 to rise. At this time, the upper end of the support member 2 is located between the two fixed blocks 14, and then the two clamping plates 12 are changed from the clamping state to the loosened state, and the two support blocks 25 are driven by the driving rod 15 to clamp the support member 2 due to the action of the pushing member 11 driving the clamping plate 12 to retract. The subsequent lifting member 10 drives the clamping plate 12 in the loosened state to descend, and then the pushing member 11 pushes the clamping plate 12 again to clamp the support member 2. At this time, the two fixed blocks 14 are in a loose state with respect to the support member 2, and the subsequent lifting device lifts again, so that the lifting of the unit height of the support member 2 is completed, and this reciprocating process can complete the lifting of the support member 2.

[0053] Embodiment 2:

[0054] Embodiment 2 of the present application provides a method for lifting a building support, which uses a building support lifting device in the above embodiment 1, and includes the following steps:

[0055] S100: fix the support frame 1 on one side of the building, and put the support member 2 into the guide sleeve 6 and the collar 28 from the bottom of the support frame 1, and the lower clamping assembly 4 clamps the support member 2, and the upper clamping assembly 5 is in a loose state;

[0056] S200: the lifting assembly 3 drives the lower clamping assembly 4 to rise, thereby driving the support member 2 to rise, driving the lower clamping assembly 4 to release the support member 2, and at this time, the upper clamping assembly 5 plays a clamping role on the support member 2;

[0057] S300: After the lifting assembly 3 drives the lower clamping assembly 4 to descend, the lower clamping assembly 4 clamps the support member 2 again, and at this time, the upper clamping assembly 5 is in a released state with respect to the support member 2;

[0058] S400: Repeat steps S200 and S300 until the support member 2 rises to a designated position.

[0059] Embodiment 3:

[0060] Reference Figure 4 Embodiment 3 of the present application further provides a construction method for a building support device, which comprises the following steps for a building support jacking device in the above embodiment 1:

[0061] S100: Fix the support frame 1 at a position below the floor slab and close to the wall, and fix the position of the support frame 1 by anchor bolts;

[0062] S200: Place the first support member 2 under the support frame 1 so that the lower clamping assembly 4 clamps the support member 2. At this time, the upper clamping assembly 5 is in a loose state;

[0063] S300: The lifting assembly 3 lifts the support member 2 so that the height of one end of the support member 2 is higher than the height of the upper clamping assembly 5. Then the lower clamping assembly 4 is loosened, and the upper clamping assembly 5 clamps the support member 2 to fix the height of the support member 2;

[0064] S400: After the support member 2 of the current segment rises to a certain height, connect the support member 2 of another segment with the support member 2 of the current segment under the support frame 1 and continue to lift according to the lifting steps of the support member 2 of the current segment;

[0065] S500: Connect the support member 2 that has risen to the target height with the truss structure on the wall, thereby realizing the connection between the support member 2 and the wall.

[0066] Further, a drill bit with its own drive and power supply can be installed on the uppermost support member 2 so that when the uppermost one abuts against the floor slab, the drill bit can drill holes in the floor slab, thereby realizing the penetration of the support member 2 between the floor slabs.

[0067] Through the above construction method, it is possible to connect the support member 2 while lifting it. At the same time, during the lifting process, the drill bit can be started to drill holes in the floor slab, thereby realizing the layer-by-layer drilling of the floor slab. Compared with the method of drilling holes in all floor slabs at one time, the stability of the floor slab is improved, and thus the stability of the wall is improved. At the same time, after the support member 2 is lifted in place, a truss structure can be installed on the wall and connected with the support member 2, and the connection between the truss structure and the support member 2 plays a supporting role for the wall, achieving the effect of protecting the wall.

[0068] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
