Description

Technical Field

[0001] The utility model belongs to the technical field of building tilt correction, and in particular relates to a displacement monitoring device for building jacking and tilt correction. Background Art

[0002] Uneven settlement of existing buildings will lead to the destruction of the stability and integrity of the superstructure, resulting in the tilt of the building, and even damage such as cracking and deformation of the wall, which will affect its continued use and even cause the entire building to collapse. The building jacking and tilt correction technology uses jacks to achieve jacking and tilt correction of the superstructure. During the jacking and tilt correction process, jacks are usually used to jack up simultaneously on both sides of the original building structure. Since the jacking amount of each jacking point is different, during the jacking and tilt correction construction, the superstructure is easily corrected or over-topped due to inaccurate control of the jacking amount and asynchronous jacking displacement, thereby affecting the construction quality of the building during the jacking and tilt correction process.

The lifting part 2 is located on both sides of the original wall 1, and the original wall 1 is provided above and below the lifting part 2. The connecting member 6 is installed between the lifting part 2 and the original wall 1, and is located at the bottom of the lifting part 2. The connection strength between the original wall 1 and the lifting part 2 can be strengthened by the connecting member 6. At the same time, the connecting member 6 is installed between the original wall 1 and the lifting part 2, and the lifting amount changes of the original wall 1 and the lifting part 2 can be synchronously monitored.

[0033] In some embodiments, the connecting member 6 may be Figure 2 See the structure shown. Figure 2The connecting member 6 includes a first wing plate 61 and a second wing plate 62 which are perpendicular to each other. The first wing plate 61 is fixedly mounted on the bottom of the lifting part 2, and the second wing plate 62 is fixedly mounted on the side of the original wall 1. The connecting member 6 is made of angle steel. The first wing plate 61 and the second wing plate 62 are perpendicular to each other and are fixedly mounted on the lifting part 2 and the original wall 1 respectively by expansion bolts. A hook 7 is fixedly mounted on the bottom surface of the first wing plate 61, and the hook 7 is used to connect the wire on the wire displacement meter 4. The setting of the first wing plate 61 and the second wing plate 62 can enhance the stability of the connection position between the connecting member 6 and the original wall 1 and the lifting part 2, and ensure the accuracy of the later lifting amount measurement.

[0034] In some embodiments, the level measuring device 5 may be implemented as follows: Figure 1 , Figure 2 and Figure 3 See also Figure 1 , Figure 2 and Figure 3 , the level measuring device 5 is installed on two second wing plates 62 located on both sides of the original wall 1 and is set through the original wall 1.
