Abstract

The invention discloses a method for cutting a square groove on a building wall or floor. A square groove position line is drawn on the wall or floor, a positioning hole is drilled in the center of the square groove position line, and then the inner edge of the square groove position line is drilled. Drill a slotted hole, adjust the sliding side plate frame, align the frame formed by the sliding side plate frame and the right-angle plate connector with the size of the square slot, lock the positioning ruler, move the slot milling drill and align the position of the slot milling hole, and center the positioning axis The upper end of the shaft head is clamped on the hand drill; insert the milling drill into the milling hole, insert the inner end of the central positioning shaft into the positioning hole, press the hand drill to the wall or floor, start the hand drill, The slot milling drill continuously mills the back-shaped slot on the wall or floor, remove the square slot milling equipment, and knock out the remaining bosses in the square slot. The invention solves the problems that there is no special tool for opening the square groove on the wall or the floor, the efficiency of manually opening the square groove is low, the wall or the floor is easy to be damaged, and the size of the opened square groove often does not match the design.

Description

technical field [0001] The invention relates to the field of building decoration tool equipment and technology, in particular to a method for opening a square groove on a building wall or floor. Background technique [0002] In the process of house decoration, it is often necessary to open square grooves on the wall or floor to install various control boards or plug-in boards. Since the wall is mainly made of bricks or concrete, the floor is mostly made of concrete. The material is relatively hard. If it is necessary to open a square groove on the wall or floor during decoration, there is no special equipment for opening a square groove in the prior art. Generally, workers use saw blades to cut a well on the wall or floor. T-shaped groove, and then use tools to dig out the bricks or concrete in the square groove to form a square groove. This method of opening a square groove is inefficient. Using a saw blade to cut a well-shaped groove will cause damage to the wall structure...
