[0081] Referring to Figure 2 and Figure 3 , Figure 2 a cutting schematic view of the building indoor stand column is shown, Figure 3 a flow schematic view of the construction method of the building indoor space expansion is shown. The construction method of the building indoor space expansion comprises the following steps.

[0082] The step S210 is performed: holes are drilled at the first elevation and the second elevation on the hollow stand column 20 by the electric drill 153, to obtain the first drill hole 21 and the second drill hole 22.

[0083] The first elevation is one meter from the ground, and the first drill hole 21 is drilled at this position. The second elevation is one and a half meters from the ground, and the second drill hole 22 is drilled at this position. This facilitates the subsequent extension of the air bag 151 and provides space for subsequent operations.

[0084] In this embodiment, the column 20 has pipes and wires arranged inside the building, and the pipes and wires need to be protected. The first elevation is set to be lower than the lowest position of the pipes and wires arranged inside the building, so as to avoid the pipes and wires. Then, step S220 is performed.

[0085] Step S220 is performed: the third material pipe 18 is extended into the column 20 from the first drill hole 21, and the waste material in the column 20 is pumped out by the material pump 17.

[0086] The waste material includes the debris generated during the drilling process and falling into the column 20. Then, step S230 is performed.

[0087] Step S230 is performed: the air bag 151 is inserted into the first drill hole 21, and the air pump 152 is used to inflate the air bag 151. The air bag 151 expands in the column 20 and divides the interior of the column 20 into an upper space and a lower space.

[0088] The air bag 151 is in close contact with the inner wall of the column 20, and the upper space and the lower space are not communicated. Then, step S240 is performed.

[0089] Step S240 is performed: the first material pipe 121 is inserted into the second drill hole 22, and the switch of the material pump 122 is turned on. The filler material can be input into the upper space of the column 20.

[0090] The filler material partially fills the upper space inside the column 20, which is used to reinforce the column 20. Then, step S250 is performed.

[0091] Step S250 is performed: the screw rod 133 and the lifting block 134 are screwed together in the polishing unit 14, so as to control the lifting of the polishing unit 14 to the target height.

[0092] After the filler material is dried, the operator holds the second handle 131, and the second motor 142 drives the screw rod 133 to rotate and adjust the height of the polishing unit 14. Then, step S260 is performed.

[0093] Step S260 is performed: the polishing unit 14 is used to cut and polish the target height of the column 20, so as to cut off the column wall of the column 20 except the filled section, and increase the indoor space of the building.

[0094] Among them, the column 20 with the filled part is retained, the upper side of the filled section is cut off, and the outer wall of the column 20 located in the lower space is also cut off. This does not affect the positioning of the internal pipes and wires of the column 20, and at the same time, it will free up some space and increase the indoor space. The column 20 is easy to cut and grind by grinding wheel 147, which effectively expands the indoor space.

[0095] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
