[0040] Please refer to Figure 1-8 This invention provides a technical solution:

[0041] A building inclination detection device includes an inclination sensor 1 and a connection frame 3 for connecting with a building wall.

A round hole 72 is opened at one end of the resistance backing plate 71 away from the connection member 6. Adsorption holes 73 are opened around the round hole 72. A negative pressure mechanism 75 is arranged inside one end of the resistance backing plate 71 away from the connection member 6. A control bolt 76 is spirally connected to the top end of the resistance backing plate 71. A connection unit 74 is arranged at the other end of the resistance backing plate 71. A washer 8 is arranged between the resistance backing plate 71 and the connection frame 3.

[0042] As a further technical solution of this scheme, the connection frame 3 includes a frame body 31. Threaded holes 32 for connecting with the connection bolt 2 are opened at both ends of the frame body 31. Reinforcing ribs 33 are arranged at the bending parts of the upper end and the lower end of the frame body 31. Through the above settings, the inclination sensor 1 and the building wall can be stably connected;

[0043] As a further technical solution of this scheme, the frame body 31 is U-shaped. The frame body 31 and the washer 8 are fixedly connected by welding. A perforation for the expansion bolt 4 to pass through is opened at the connection part of the frame body 31 and the washer 8. Expansion bolts 4 for fixing with the building wall are installed on the inner sides of the upper end and the lower end of the frame body 31. A locking nut 5 is spirally connected to the position where the expansion bolt 4 is exposed outside the building wall. Through the above settings, the frame body 31 and the building wall can be stably connected;

[0044] As a further technical solution for the implementation of this solution, the middle part between the fixed block 61 and the frame body 31 is welded and fixed. The fixed block 61 is connected to the connection unit 74 through the rotation hole 62 and the limit groove 63. The connection unit 74 includes a rotating shaft 741. One side of the rotating shaft 741 is fixedly connected with a limit block 742 and an indicating needle 744. The inner side of the limit block 742 is fixedly connected with a first spring 743. Through the above settings, the inclination angle of the reverse-resistant backing plate 71 can be understood through the indicating needle 744;

[0045] As a further technical solution for the implementation of this solution, the indicating needle 744 is arranged on one side of the scale groove 64. The top of the indicating needle 744 is sharp. The included angle between the indicating needle 744 and the rotating shaft 741 is 90°. Through the above settings, the stability of the indicating needle 744 after installation can be effectively improved;

[0046] As a further technical solution for the implementation of this solution, the fixed block 61 is rotationally connected to the rotating shaft 741 through the rotation hole 62. The limit groove 63 opened inside the fixed block 61 is internally provided with a limit block 742 and a first spring 743. The limit block 742 is rotationally connected to the fixed block 61 through the limit groove 63. Through the above settings, the stability of the overall equipment after installation can be further improved;

[0047] As a further technical solution for the implementation of this solution, the negative pressure mechanism 75 includes an inclined block 751. One end of the inclined block 751 is fixedly connected with an annular plate 753. The other end of the annular plate 753 is fixedly connected with a second spring 754. The annular plate 753 is slidably connected inside the annular groove 752. The annular groove 752 is opened inside the end of the reverse-resistant backing plate 71 far from the connecting member 6. Through the above settings, the problem of loosening of the control bolt 76 can be effectively prevented;

[0048] As a further technical solution for the implementation of this solution, a plurality of adsorption holes 73 are provided. The adsorption holes 73 are arranged at equal intervals in a ring shape. The adsorption holes 73 are communicated with the annular groove 752. One end of the adsorption hole 73 far from the connecting frame 3 is provided with a flared opening. Through the above settings, the stability of the control bolt 76 after installation can be further improved;

[0049] As a further technical solution for the implementation of this solution, the gaskets 8, expansion bolts 4 and locking nuts 5 correspond to each other one by one. The expansion bolts 4 are arranged in the circular holes 72 opened inside the reverse-resistant backing plate 71. Through the above settings, the reverse-resistant backing plate 71 can be effectively positioned;

[0050] As a further technical solution for the implementation of this solution, the vertical cross-section of the bottom end of the control bolt 76 is trapezoidal. Through the above settings, the annular plate 753 can be pushed to move by the control bolt 76.

[0051] Workflow: During the process of continuously detecting the inclination of a building, the staff connects the expansion bolt 4 to the building wall to be detected. After the connection is completed, the expansion bolt 4 is docked with the connecting frame 3. During the connection process, the connecting frame 3 is positioned by connecting the locking bolt 5 to the expansion bolt 4. During the installation of the locking bolt 5, the reverse pad 71 is squeezed. During the squeezing process, due to the deformation of the connecting frame 3 and the building wall, there is a problem of the reverse pad 71 rotating. By comparing the rotation of the two reverse pads 71, the installation force of the locking bolt 5 can be intuitively understood, which is realized by the cooperation of the indicating needle 744 and the scale groove 64;

[0052] After the installation is completed, the inclination sensor 1 can be fixed by the connecting bolt 2. The fixed inclination sensor 1 has the same inclination as the building wall, thus ensuring the accuracy of the detection data;

[0053] In the later detection process, construction activities such as pile driving, dynamic compaction, blasting, and vibrating rolling at the construction site will generate strong vibrations. These vibrations will spread through the soil and building structure, causing vibrations on the building wall. In addition, the operation of heavy machinery and equipment used during the construction process will also cause vibrations, which will cause the connecting frame 3 to loosen. At this time, tighten the control bolt 76. During the movement of the control bolt 76, the ring plate 753 is controlled to move by the inclined block 751, and then the adsorption hole 73 adsorbs the locking nut 5, which can effectively prevent the locking nut 5 from loosening due to vibrations during use, and thus effectively improve the accuracy of the detection data of the inclination sensor 1.

The description of the above examples is only used to help understand the method of the present invention and its core idea. The above is only the preferred implementation method of the present invention. It should be noted that due to the limitation of literal expression and objectively existing infinite specific structures, for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements, retouches or changes can be made, or the above technical features can be combined in an appropriate way; these improvements, retouches, changes or combinations, or directly applying the concept and technical solution of the invention to other occasions without improvement, should all be regarded as the protection scope of the present invention.
