[0081] See also Figure 2 and Figure 3 , Figure 2 The schematic diagram of cutting the indoor columns of the building of the present invention is shown. Figure 3 The present invention provides a construction method for expanding the indoor space of a building, comprising the following steps:

[0082] Execute step S210: Use the electric drill 153 to drill holes at the first elevation and the second elevation on the hollow column 20 to obtain a first borehole 21 and a second borehole 22 .

[0083] Among them, the first elevation is one meter from the ground, and the first borehole 21 is drilled, and the second elevation is one and a half meters from the ground, and the second borehole 22 is drilled, which is convenient for the subsequent insertion operation of the airbag 151 and provides space for subsequent operations.

[0084] In this embodiment, there are pipes and wires arranged in the building inside the column 20, and the pipes and wires need to be protected to retain the original positioning effect. The first elevation is set to be lower than the lowest position of the arranged pipes and wires to avoid the pipes and wires, and then step S220 is executed.

[0085] Execute step S220: extend the third material passage pipe 18 into the column 20 from the first borehole 21, and use the material extraction pump 17 to extract the waste material in the column 20.

[0086] The waste materials include crushed stones generated during the drilling process and falling into the column 20. Then, step S230 is performed.

[0087] Execute step S230: insert the airbag 151 into the first drilled hole 21, and inflate the airbag 151 with the air pump 152. The airbag 151 expands in the column 20 and divides the interior of the column 20 into an upper space and a lower space.

[0088] The airbag 151 is in close contact with the inner wall of the pillar 20 , and the upper space is not connected with the lower space. Then, step S240 is executed.

[0089] Execute step S240 : insert the first material passage pipe 121 into the second borehole 22 , turn on the switch of the material pump 122 , and input the filling material into the upper space of the column 20 .

[0090] The filling material partially fills the upper space inside the column 20 in order to reinforce the column 20 . Then, step S250 is performed.

[0091] Execute step S250: by cooperating between the screw rod 133 in the grinding unit 14 and the thread of the lifting block 134, the grinding unit 14 can be controlled to be lifted to a target height.

[0092] After waiting for the filling material to dry, the operator holds the second handle 131 and drives the screw 133 to rotate and adjust the height of the grinding unit 14 through the second motor 142, and then executes step S260.

[0093] Execute step S260: cut and grind the target height of the column 20 by the grinding unit 14, and remove the column wall of the column 20 except the filling section to increase the indoor space of the building.

[0094] Among them, the filled part of the column 20 is retained, the upper side of the filling section is cut off, and the outer wall of the column 20 located in the lower space is also cut off. This will not affect the positioning of the internal pipes and wires by the column 20, and at the same time, a part of the space will be freed up, thereby increasing the indoor space. The grinding wheel 147 is used to facilitate the cutting and grinding of the column 20, thereby effectively expanding the indoor space.
