Description

Technical Field

[0001] The utility model relates to the technical field of building construction measurement supporting equipment, in particular to a device for measuring and correcting benchmark points of super high-rise buildings. Background Art

[0002] In the construction of super high-rise buildings, it is necessary to accurately control the verticality of the building. During measurement, it is necessary to set up a laser receiving point and use a total station or a satellite receiver to correct the accuracy of the receiving point. Usually, the measuring equipment is set on the floor slab, but in the absence of a floor slab, a support frame needs to be set up. At this stage, two V-shaped brackets are usually installed on the outer surface of the building, and corrugated plates are fixed above the two V-shaped brackets. Then, the laser receiving point and the total station are set on the corrugated plate for measurement. However, in super high-rise buildings, other factors such as wind and floor height will cause the erected corrugated plate to shake, making its stability worse and affecting the measurement accuracy.

[0022] Adjustment holes 4 are arranged on the upper frame 20 and the lower frame 21. The adjustment holes 4 are square or long waist-shaped. The adjustment holes 4 on the upper frame 20 are longer than those on the lower frame 21, so that the inner control points transmitted upward can be retracted as the cross section of the core tube changes.

Specifically, the telescopic rod is a spiral locking type, a bamboo type or other telescopic type, and can adjust the vertical height. A target 6 and a measuring instrument 7 are detachably mounted on the support rod 5 through fasteners or spirals. The measuring instrument 7 is a laser plumb line, a total station or a satellite positioning receiver. The laser plumb line is used as a leverage point to continue to hit the laser transmission axis control point upward. The total station is used to measure and correct the surrounding measurement control construction layer walls, columns and other components.

The laser is emitted by a laser plumb meter of a calibration device disposed on the ground or below. A hole is opened on the completed floor slab. The laser passes through the hole and is captured by the laser point catcher 11 to form an axis control point for measuring and controlling the construction layer wall and column components. When the axis control point needs to be close to the super-high-rise core tube 1, the laser point catcher 11 can be moved on the lower shelf 21.
