Description

Device for measuring inclination of building

Technical Field

The utility model relates to a device that is used for building gradient measurement such as house, specifically speaking relate to one kind through direct measurement building outer wall top and bottom discrepancy in elevation and horizontal displacement and indirectly try to get its gradient.

Technical Field

The inclination of the building is one of the important indexes for evaluating the safety of the building, and according to the regulation of JGJ 125-. If the inclination of the building is too large, the safety of the structure is seriously influenced, and the life and property of people are threatened, so that the inclination of the building needs to be monitored in real time or measured regularly. At present, the conventional method for detecting the inclination of the building mainly comprises total station measurement, drop hammer measurement and running rule measurement.

When the total station reflector plate technology is adopted to measure the inclination of a high-rise building, firstly, a datum point and an observation point are buried, a prism-free total station is selected, then according to the requirement of 'building deformation measurement regulation' on the secondary deformation measurement grade, 2-time-finding is carried out on a horizontal angle, 2-time-finding is carried out on a vertical angle, 2-time-finding is carried out on a distance measurement, 4 readings are carried out on each time-finding, the three-dimensional coordinates of the inclined monitoring point on the building are directly observed through the high-precision total station, the offset of the monitoring point between a building main body or each floor in the horizontal direction and the vertical direction is obtained, and finally, the integral. At present, the total station measurement is a relatively accurate measurement method, however, the method has many defects, firstly, the procedure is very complicated, the inclination can be accurately measured only through a special measurement step of professional equipment by professional personnel of a professional organization, a large amount of manpower and material resources are needed, secondly, errors exist in each step of the measurement process inevitably, and then, the procedure errors are gradually accumulated step by step, and finally, the measured inclination result may be inaccurate. Meanwhile, the method can only detect regularly and cannot detect in real time.

The hanging hammer is mainly used for manual observation, is greatly influenced by the site environment, has high requirement on the measurement environment, and can not accurately measure the inclination of the building even in the presence of small wind on the site.
