Embodiment

[0045] First, select the installation position of the monitoring body 2, requiring a structure with a certain height or a towering equipment side wall, fasten the three-dimensional rotating fixture 3 on the top of the monitoring body 2 and install it at the target position, and the monitoring body 2 is in a natural drooping state;

[0046] The scale light-transmitting plate 7 is installed at the bottom of the monitoring body 2, and its scale line should be parallel to the side of the building body, and then the position of the monitoring body 2 is adjusted left and right or front and rear through the three-dimensional rotating fixture 3 to ensure that the center point of the laser weight 9 is in line with the scale transparency. The centers of the light panels 7 coincide;

[0047] Then open the reflective observation cover 6, turn on the laser on the laser weight 9, and read the light spot projected by the laser onto the scale transparent plate 7 through the reflective observat...

Abstract

The invention discloses an automatic settlement monitoring device for large buildings or towering equipment and a use method. The automatic settlement monitoring device comprises a monitoring body which is arranged on one side of a vertical face of a building side wall, and has the upper end connected with the building side wall through a three-dimensional rotation fixing piece; a laser hammer which freely droops and is hung in the monitoring body; and a scale light-transmitting plate which is mounted at the bottom of the monitoring body. Laser emitted by the lower end of the laser hammer is projected to the scale light-transmitting plate to form a light spot, and settlement deviation can be visually monitored by observing the displacement of the light spot. The device is simple in structure, does not need a traditional monitoring instrument, and can observe at any time and immediately find whether a building, a structure or installed large-scale equipment is settled or not.

Description

technical field [0001] The invention relates to the field of settlement monitoring, in particular to an automatic settlement monitoring device for large buildings or high-rise equipment and a method for using it. Background technique [0002] At present, buildings, structures or installed towering large-scale equipment are prone to overall or partial settlement due to the uncertainty of foundation deformation of the building or equipment foundation, which will affect normal use in severe cases. The traditional measure is to use a level to check whether the building has settled. The method is to set a permanent basic observation point in an outdoor area that cannot be settled, set a permanent observation point for the observed object, and then record the first data through the level measurement. After a certain period of time, the second monitoring is carried out, and the initial data is compared to determine whether the object has settled and deformed, and so on, and long-te...
