Building floor interval measuring device

Abstract

The invention discloses a building floor interval measuring device. The building floor interval measuring device comprises a bracket and a rangefinder base; the upper end of the bracket is in shafted connection with a bottom plate; a side surface of the rangefinder base is provided with a side plate; screw holes are formed in the surfaces of the side plate and the bottom plate respectively; bolts are installed in the screw holes through threaded connection; the surface of the side plate is provided with a bubble level and a groove; the middle of the lower end of the groove is in shafted connection with a magnetic needle; two sides of the upper surface of the rangefinder base are both provided with a smooth passage; threaded rods are arranged in the smooth passages; and the upper ends of the threaded rods are connected with strip-shaped plates through threaded connection. According to the building floor interval measuring device, a rangefinder is fixed through the clamping of the strip-shaped plates; the bolts can be adjusted according to the bubble level, so that the rangefinder can be kept balanced; with the magnetic needle adopted as reference, the support can be adjusted, so that the rangefinder can be located at the vertical surface of the facade of a building; and therefore, errors in floor interval measurement can be decreased, and a situation that a floor interval measurement result is smaller or larger than an actual floor interval can be avoided.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a device for measuring building floor intervals. Background technique [0002] my country's economy is developing rapidly, and the construction industry is one of my country's pillar industries. Construction requires accurate data measurement. At present, the hand-held range finder is commonly used, and the value should be very accurate in theory. However, in practice, we found that the hand-held range finder still has a large measurement error. The main problem is that the range finder is placed There is a certain angle between the time and the horizontal and vertical directions, which is the key to the large error in the measured data. Although the bottom of the current rangefinder is designed as a plane and perpendicular to the launch port, it cannot guarantee the measurement of the ground and wall. It is also horizontal or vertical or even smooth, and there ...

The main problem is that the range finder is placed There is a certain angle between the time and the horizontal and vertical directions, which is the key to the large error in the measured data. Although the bottom of the current rangefinder is designed as a plane and perpendicular to the launch port, it cannot guarantee the measurement of the ground and wall. It is also horizontal or vertical or even smooth, there are errors in these cases
