Description

Technical Field

[0001] The utility model belongs to the technical field of large-span grid installation, in particular to a height difference detection device for lifting a grid roof. Background Art

[0002] With the continuous improvement of my country's urbanization construction level, spatial grid structures of various shapes are increasingly used in real life, especially the use of large-span spatial grid structures is becoming more and more widespread; however, as the span of spatial grid structures continues to increase, the builders have higher and higher requirements for the accuracy of the grid construction process. How to increase the installation efficiency of the entire grid structure construction process while ensuring safety is an important factor affecting whether the grid structure can develop rapidly; therefore, in the process of installing large-span grids, it is necessary to finely control its installation accuracy, including the process of lifting the grid roof. In this process, the height difference detection device is used to determine the height difference of each end face of the grid roof for detection. According to the detection data, the deviation position can be corrected in time to ensure the synchronization of the lifting process.

[0003] The existing height difference detection device for lifting the grid roof is mainly a ruler. When in use, a ruler is hung on the rod near each lifting point of the grid in advance. When the grid is lifted, the reading of the ruler is observed to determine the synchronization rate of the lifting process. When it is found that the reading of the ruler is greatly deviated from the theoretical value, the lifting is suspended.

[0004] The height difference detection device for lifting the grid roof requires manual observation of different positions of the grid roof with the naked eye, and accurate readings of the positions are required. However, during the installation and lifting process, people are not allowed to stand in the construction area below the grid roof. Therefore, not only will reading errors occur, but running back and forth between different areas of the grid roof will also greatly delay the lifting work. Also, as the grid roof is lifted, the tape measure is stretched, but in order to make the tape measure detachable later, the end of the tape measure can only be hung on the rod, which is easy to detach from the rod. To this end, we provide a height difference detection device for lifting the grid roof to solve the above problems. Utility Model Content
