Description

Technical Field

[0001] The utility model belongs to the technical field of highway prefabricated beam construction, in particular to an intelligent numerical control adjustment device for the oil top of a bottom mold of a wedge-shaped block of a prefabricated beam. Background Art

[0002] When designing bridges and roads, there will be longitudinal slopes and transverse slopes, which will cause the bottom surface of the beam to be non-horizontal when in use, so wedge blocks need to be set at the bottom of the beam at both ends of the bridge for leveling to ensure horizontal contact between the bottom of the beam and the support. When the beam has a longitudinal slope, a wedge block with the same slope as the longitudinal slope of the bridge is set between the bottom of the beam and the support for leveling. When the beam has both a longitudinal slope and a transverse slope, two wedge blocks with the same slope as the longitudinal slope and transverse slope of the bridge are set between the beam and the support for leveling. After leveling the bottom of the beam at the two supporting points, it is in horizontal contact with the top surface of the support.

[0003] The traditional method for adjusting the bottom form of the wedge block is the sand laying method. According to the size of the wedge block of the prefabricated beam section, the thickness of the dry sand laying is calculated, and the ink line is drawn on the inner side of the reserved groove of the pedestal, and the dry sand is laid according to the ink line position. The steel plate is placed, the relative height difference is observed with a level, and then the surface of the dry sand is adjusted. This method is slow, and the compression and deformation of the sand will cause the wedge block size to be inaccurate. If the elevation of the wedge block is inaccurate, the wedge block and the support will not fit after the box beam is installed, and the support will be unevenly stressed, affecting the service life of the bridge support. Therefore, the quality control of the wedge block construction at the bottom of the beam is extremely important to ensure the slope of the bridge deck and the service life of the bridge.
