Description

Technical Field

[0001] The present invention relates to the field of construction engineering safety monitoring, and in particular to a construction engineering verticality monitoring device and a use method thereof. Background Art

[0002] Building verticality refers to the degree of deviation between the actual axis of a building or its components in the vertical direction and the designed axis. This deviation directly affects building safety, equipment installation accuracy and structural durability. In particular, in high-rise buildings, verticality deviation must be strictly controlled within the allowable range. In order to ensure the safety of building use, it is usually necessary to monitor the verticality of the building in real time so as to promptly discover and deal with the safety hazards of the building. The traditional method of measuring the verticality of the building is mainly the plumb line method, which usually uses a hanging plumb line to measure the verticality of the building. The verticality is judged by observing the distance deviation between the plumb line and the formwork or wall. It is easily affected by wind or vibration, especially when the shaking causes the plumb line to swing back and forth continuously, which often causes the alarm to be falsely triggered, affecting the monitoring results. Therefore, a construction project verticality monitoring device and a method for use are proposed. Summary of the Invention

[0012] A method for using a construction engineering verticality monitoring device comprises the following steps: Step S1: Place the monitoring device body on the top plane of the building, and insert the fixing pins through the through holes on the supporting base plate into the top plane of the building; Step S2, fixing the bottom end of the limiting tube to the center position of the bottom plate inside the main body shell; Step S3, connecting the conductive ring to the connecting wire and installing it in the annular connecting groove; Step S4, placing the annular bracket inside the main housing so that the threaded hole at the end of the bracket connecting rod is aligned with the opening on the side of the main housing; Step S5, installing the connecting bolts so that the connecting bolts pass through the side of the main body shell and connect with the threaded holes at the end of the bracket connecting rod; Step S6, putting the hanging hammer body on the hanging hammer connecting line; Step S7, installing a conductive rod at the bottom of the pendulum body, so that the conductive rod is connected to the internal wire of the pendulum connection line; Step S8, fixing the top end of the pendulum connection line to the center position inside the protective top cover, so that the internal wire of the pendulum connection line is connected to the connecting wire; Step S9, fixing the bottom end of the hanging hammer connecting line to the top of the reset slider; Step S10: placing the reset slider inside the limiting tube so that the reset slider can slide up and down inside the limiting tube; Step S11, adjusting the height of the hammer body on the hammer connecting line so that the hammer body is located above the trigger mechanism; Step S12, adjusting the height of the conductive rod on the pendulum connection line so that the conductive rod is located at the center of the conductive ring; Step S13, installing the transparent connection cover on the top of the main shell, and installing the protective top cover on the top of the transparent connection cover; Step S14: When the building tilts, the main body housing fixed to the top of the building, together with the trigger mechanism and the conductive ring, tilts along with the building.
