technical field
[0001] The invention relates to the technical field of building construction, in particular to an adjustable support frame suitable for vertically upward drilling construction on concrete floors and beam bottoms. Background technique
[0002] In the construction of construction projects, it is often necessary to drill holes vertically upwards on the bottom of concrete floors and beams in order to complete the installation of other facilities. For this type of vertical drilling, the usual construction method is to use a ladder or set up a scaffold for the operator to carry out the drilling operation. However, the disadvantage of this method is that the operator lifts the drilling rig with his arms in the air for a long time. The labor intensity is high, the construction efficiency is low, and the dust generated during drilling is likely to cause damage to the operator's eyes, which is not conducive to safe construction; moreover, the operator can only judge an...
