High-altitude drill positioning method of building

Abstract

The invention discloses a high-altitude drill positioning method of a building, which comprises a high-altitude marking device, a high-altitude drilling device and a high-altitude tightening device. The high-altitude drill positioning method comprises the following steps that when a plurality of fixing holes need to be drilled in the top surface of the building, the length of an adjustment rod of the high-altitude marking device is adjusted to be equal to the distance between any two fixing holes; a support rod of the high-altitude marking device is adjusted, so that the altitude from the top end of a marking rod to the ground is equal to the altitude from the fixing holes to the ground; the marking end head is pressed to the top surface, so as to draw marking points of the two fixing holes; the high-altitude drilling device is placed below the fixing holes, and a handle is pressed downward, so that a drill which is fixedly arranged on drilling equipment aligns with the marking points of the fixing holes; the drilling equipment is turned on to drill the holes which conform to a size; one end of an expansion bolt, which is provided with a nut, is inserted into the top end of the high-altitude tightening device; the expansion end of the bolt is inserted into a drilled fixing hole, and then a handle of the high-altitude tightening device is rotated to tighten the expansion bolt; and the steps are repeated, so as to complete the drill tightening operation of the remaining fixing holes. According to the high-altitude drill positioning method, the disadvantages of low construction quality and large difficulty because no reliable application point exists at high altitude are overcome, the construction quality is guaranteed, various potential safety hazards due to high-altitude construction of construction personnel are avoided, and the construction efficiency is greatly increased.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a positioning method for drilling holes in high places of buildings. Background technique [0002] There is a lot of work in construction engineering that requires construction workers to climb to high places in buildings to perform related operations. The current method of fixing certain devices (such as air conditioners, lamps, etc.) on high places in buildings is cumbersome and dangerous. First of all, it is necessary to mark the position of the fixing holes, and then drill the holes. After all the fixing holes are drilled, insert the expansion bolts and tighten them. All the above-mentioned operations need to be completed by construction personnel with the help of ladders and other climbing equipment. Since there is no reliable focus point for construction at high places, the operation is difficult and the quality of the work cannot be guaranteed. Drilling holes an...

All the above-mentioned operations need to be completed by construction personnel with the help of ladders and other climbing equipment. Since there is no reliable focus point for construction at high places, the operation is difficult and the quality of the work cannot be guaranteed. Drilling and fastening bolts require construction workers to move constantly, which greatly increases the safety hazards of construction workers during the process of repeatedly climbing and descending the ladder
