Description

Technical Field

[0001] The invention relates to the technical field of building jacking, and in particular to a jacking device and a construction method for building demolition. Background Art

[0002] In order to adapt to the continuous development of my country's social and economic construction, large-scale infrastructure construction has begun to be implemented. Many cities will carry out building renovation, demolition and reconstruction, and a large number of dilapidated and aging buildings need to be demolished and rebuilt. The existing building demolition and dismantling technologies mainly include blasting demolition and mechanical demolition, but the use of blasting demolition in densely populated areas such as urban areas is dangerous and costly.

[0003] The invention with the announcement number CN110453933B discloses a jacking device and construction method for demolishing a building. By setting a lifting plate, a lifting assembly and a stacking assembly, when demolishing a high-rise building, holes are pre-punched on the floor of the building for the support rack and the main body of the demolition equipment to extend, and then the floor is dismantled by the main body of the dismantling equipment, so that the main body of the dismantling equipment dismantles the side panels of the building from top to bottom, thereby realizing the demolition of the entire building. Compared with the manual demolition of the superstructure, this method has less labor intensity for workers and higher demolition efficiency.

[0004] However, the above technical solution has the following defects: although the above building demolition internal lifting equipment can exert lifting force on the inner top of the building from different directions and angles, the effect of exerting force is single, and the result of demolition is that the inner top of the building is completely broken and separated, which is not conducive to the overall lifting, demolition and separation of the inner top.

The lifting cylinder 3 is started to lift the main lifting assembly 4, the supporting connector 5 and the removal top plate 2 to the lower surface of the inner top of the building, and the auxiliary lifting assembly 6 is started at the same time so that the rotating lifting end of the rotating lifting assembly 8 also reaches the lower surface of the inner top of the building. A driving device linkage control module is set to make the rotating lifting assembly 8 and the main lifting assembly 4 work in coordination; the screw motor 42 is started to drive the lifting sliding seat 43 to rise on the lifting frame 41, thereby driving the removal top plate 2 on the supporting connector 5 to rise. At this time, the inner top of the building is stressed, and the linkage cylinder 410 is started to further support the lifting sliding seat 43. The supporting connector 5 slowly exerts force on the inner top of the building until the support sleeve rod 52 and the sliding support rod 53 are in the longest length connection state. During the ascending process of the lifting sliding seat 43, the rotating driving motor 45 drives the rotating wheel 46 to rotate relative to the upper limit frame 47 and the lower limit frame 48, thereby applying a reverse force to prevent the removal of the top plate 2 and the support connector 5 from sliding relative to the support connector mounting seat 49. The rotating lifting assembly 8 is started, and the rotating lifting cylinder 82 is used to drive the rotating lifting plate 85 to rotate on the guide seat 84, thereby lifting the removal top plate 2, and further applying a force to the inner top of the building until the inner top of the building is separated from the side wall of the building.

Start the lifting cylinder 3 to lift the main lifting assembly 4, the supporting connector 5 and the removed top plate 2 to the lower surface of the inner top of the building, and at the same time start the auxiliary lifting assembly 6 so that the rotating lifting end of the rotating lifting assembly 8 also reaches the lower surface of the inner top of the building.

[0068] S3. Set up a driving device linkage control module to enable the rotating lifting assembly 8 and the main lifting assembly 4 to work together; start the screw motor 42 to drive the lifting sliding seat 43 to rise on the lifting frame 41, thereby driving the removal top plate 2 on the supporting connecting member 5 to rise.

[0069] S4, at this time, the top of the building is stressed, and the linkage cylinder 410 is started to further support the lifting sliding seat 43.

[0070] S5, the supporting connector 5 slowly applies force to the inner top of the building until the supporting sleeve rod 52 and the sliding supporting rod 53 are in the longest length connection state.

[0071] S6. During the ascending process of the lifting sliding seat 43, the rotating driving motor 45 drives the rotating wheel 46 to rotate relative to the upper limit frame 47 and the lower limit frame 48, thereby applying a reverse force to prevent the top plate 2 and the support connecting member 5 from being dismantled and sliding relative to the support connecting member mounting seat 49.

[0072] S7, start the rotating lifting assembly 8, use the rotating lifting cylinder 82 to drive the rotating lifting plate 85 to rotate on the guide seat 84, so as to lift and remove the top plate 2, and further apply force to the inner top of the building until the inner top of the building is separated from the side wall of the building.
