The outer formwork 100 is installed in the reserved hole of the building. The outer formwork 100 is made of plastic material, and the inner cylinder 200 is arranged inside the outer formwork 100 for internal support of the outer formwork 100 to prevent the pressure of the building from exerting pressure on the outer formwork 100, so as to prevent the outer formwork 100 from collapsing or deforming and affecting the reservation of the reserved hole. The inner cylinder 200 includes a first support mechanism 210, a second support mechanism 220 and a third support mechanism 230. The structures of the first support mechanism 210, the second support mechanism 220 and the third support mechanism 230 are suitable, and the first support mechanism 210, the second support mechanism 220 and the third support mechanism 230 are connected in a side-by-side spiral connection along the horizontal direction, so that the inner cylinder 200 can be connected with different numbers of support mechanisms in spiral connection according to the length of the reserved hole, so that the hole reservation device can be used for supporting reserved holes of different lengths; The second support mechanism 220 includes a connecting cylinder 221, a plurality of linkage rods 222 and a plurality of support plates 223. The connecting cylinder 221 is provided with an air inlet channel 2211 along the horizontal direction, and a plurality of moving grooves 2213 are also arranged on the connecting cylinder 221. Each moving groove 2213 is communicated with the air inlet channel 2211 through a corresponding air inlet hole 2212. A corresponding linkage rod 222 is movably installed in each moving groove 2213, and a corresponding support plate 223 is fixedly installed on each linkage rod 222, so that the high-pressure gas input into the air inlet channel 2211 can push the linkage rods 222 movably installed in each moving groove 2213 to move outwards along the moving groove 2213, so that the support plates 223 fixedly installed on the tops of the linkage rods 222 support the outer formwork 100 with different diameters.

[0027] When the hole reservation device supports the reserved hole on the wall surface of a construction project, the cylindrical outer formwork 100 on the reservation device is placed on the wall surface of the construction project. The construction workers screw and connect the first support mechanism 210, several second support mechanisms 220 and third support mechanisms 230 on the inner column cylinder 200 according to the length of the reserved hole, so that the inner column cylinder 200 can be applicable to the support of reserved holes of different lengths. The air inlet pipe 211 fixedly installed at the front end of the connecting cylinder 221 on the first support mechanism 210 is connected to an air pump. The valve 212 on the air inlet pipe 211 is opened, so that the air pump inputs high-pressure gas into the air inlet channels 2211 on the connecting cylinders 221 of the first support mechanism 210, several second support mechanisms 220 and third support mechanisms 230, so that the high-pressure gas pushes the moving grooves 2213 connected to each air inlet channel 2211, so that the linkage rods 222 movably installed in the moving grooves 2213 move outwards along the length direction of the moving grooves 2213, thereby driving the arc-shaped support plates 223 fixedly connected to the tops of the linkage rods 222 to support the outer formwork 100. The valve 212 on the air inlet pipe 211 is closed, so that the inner column cylinder 200 maintains the support state. When it is necessary to remove the hole reservation device, the valve 212 on the air inlet pipe 211 is opened, so that each support plate 223 can contract inwards, facilitating the removal of the hole reservation device and improving the efficiency of hole reservation in the construction project.

[0028] As a preferred embodiment, please refer to Figure 3 and Figure 4 , the air inlet pipe 211 is fixedly installed at the front end of the connecting cylinder 221 on the first support mechanism 210, and the air inlet pipe 211 is connected to the air inlet channel 2211, so that the air pump connected to the air inlet pipe 211 inputs high-pressure gas into the air inlet channel 2211. A valve 212 is provided on the air inlet pipe 211. The valve 212 is opened, so that the air pump inputs high-pressure gas into the connecting cylinder 221. After the inner column cylinder 200 supports the outer formwork 100 and remains stable, the valve 212 is closed, so that the inner column cylinder 200 maintains a stable support state.

[0029] As a preferred embodiment, please refer to Figure 3 and Figure 4, at the front end of the connecting cylinder 221 on the second support mechanism 220, there are a threaded pipe 2214 and a clamping pipe 2215. The threaded pipe 2214 is in a ring structure, and the clamping pipe 2215 is arranged on its outer side. At the rear end of the connecting cylinder 221, there are corresponding threaded grooves 2216 and clamping grooves 2217, so that the threaded pipe 2214 is screwed into the threaded groove 2216 arranged on the connecting cylinder 221 of the adjacent first support mechanism 210. At the same time, the clamping pipe 2215 is clamped into the clamping groove 2217 arranged on the connecting cylinder 221 of the adjacent first support mechanism 210, so that the first support mechanism 210 and the second support mechanism 220 are hermetically screwed and connected. Similarly, the connecting cylinder 221 on the third support mechanism 230 and the connecting cylinder 221 on the second support mechanism 220 are hermetically connected after being screwed with the threaded pipe 2214 screwed into the threaded groove 2216 arranged on the connecting cylinder 221 of the adjacent second support mechanism 210, so that the connecting cylinder 221 is in a cylindrical structure, thereby preventing the high-pressure gas input by the air pump from leaking.

[0030] As a preferred embodiment, please refer to Figure 3 and Figure 5 , a sealing gasket 2218 is also installed in the clamping groove 2217 for the sealing connection of the connecting cylinder 221 on the first support mechanism 210 and the second support mechanism 220.

[0031] As a preferred embodiment, please refer to Figure 4 and Figure 5 , an elastic member 225 is also installed in the moving groove 2213. The elastic member 225 is a metal spring, and the elastic member 225 is sleeved on the front end of the piston 224 on the linkage rod 222. After the high-pressure gas is input into the air inlet passage 2211, the high-pressure gas enters the moving groove 2213 from the connecting hole, thereby pushing the piston 224 installed in the moving groove 2213 to move, so that the elastic member 225 abutting against the piston 224 is compressed. After the inner cylinder 200 finishes supporting the outer template 100, the high-pressure gas is released, the elastic member 225 is relieved of pressure, and the elastic potential energy generated by the recovery of the elastic member 225 drives the abutting piston 224 to recover, so that the linkage rod 222 recovers.

[0032] As a preferred embodiment, please refer to Figure 3 and Figure 4 , the support plate 223 is an arc-shaped structural plate, so that the arc-shaped support plate 223 fits and supports the inside of the outer template 100.

[0033] As a preferred embodiment, please refer to Figure 3 , the rear end of the connecting cylinder 221 on the third support mechanism 230 is closed for closing the air inlet passage 2211.

[0034] As a preferred embodiment, please refer to Figure 1 and Figure 2, the intake pipe 211 is connected to the air pump so that the air pump can input high-pressure gas into the intake passage 2211.

[0035] The working principle of the hole reservation device for construction engineering of the present utility model is as follows:

[0036] When the hole reservation device supports the wall of the construction project to reserve holes, the cylindrical outer formwork 100 on the reservation device is placed on the wall of the construction project. The construction workers screw-connect the first support mechanism 210, several second support mechanisms 220 and third support mechanisms 230 on the inner column cylinder 200 according to the length of the reserved hole, so that the inner column cylinder 200 can be applicable to the support of reserved holes of different lengths. The intake pipe 211 fixedly installed at the front end of the connecting cylinder 221 on the first support mechanism 210 is connected to the air pump. Open the valve 212 on the intake pipe 211 so that the air pump can input high-pressure gas into the intake passage 2211 on the connecting cylinder 221 of the first support mechanism 210, several second support mechanisms 220 and third support mechanisms 230, so that the high-pressure gas pushes the moving groove 2213 connected to each intake passage 2211, so that the linkage rod 222 movably installed in the moving groove 2213 moves outward along the length direction of the moving groove 2213, thereby driving the arc-shaped support plate 223 fixedly connected to the top of the linkage rod 222 to support the outer formwork 100. Close the valve 212 on the intake pipe 211 so that the inner column cylinder 200 maintains the support state. When it is necessary to remove the hole reservation device, open the valve 212 on the intake pipe 211 so that the gas in the intake passage 2211 of each support mechanism on the inner column cylinder 200 is discharged, and the support plates 223 can contract inward, which is convenient for removing the hole reservation device, thereby improving the efficiency of hole reservation in construction projects.

[0037] The beneficial effects of the hole reservation device for construction engineering of the present utility model are as follows:

[0038] First, by setting the inner column cylinder 200 on the hole reservation device for construction engineering into a screw-connected structure, the first support mechanism 210, several second support mechanisms 220 and third support mechanisms 230 on the inner column cylinder 200 can be screwed and connected horizontally according to the length of the reserved hole, so that the hole reservation device can support the reserved holes of different lengths in construction projects, and improve the reservation efficiency of the reserved holes in construction projects;

[0039] II. By providing an air inlet passage 2211 on the first support mechanism 210, several second support mechanisms 220 and third support mechanisms 230 of the building engineering hole reservation device, the air pump can input high-pressure gas from the air inlet pipe 211 into the air inlet passage 2211 on each connected cylinder 221 screwed together. After the high-pressure gas is input, the piston 224 installed in each moving groove 2213 is pushed to move along the moving groove 2213, thereby pushing the linkage rod 222 fixedly connected to each piston 224 to move outwards, and then pushing the support rod fixedly connected to each linkage rod 222 to move outwards, so as to support the outer formwork 100 of reserved holes with different diameters and improve the reservation efficiency of reserved holes in building engineering;

[0040] III. By inputting high-pressure gas, the support diameter of each support mechanism can be quickly adjusted. At the same time, when removing, opening the air inlet valve 212 can quickly disassemble it, replacing the original mechanical adjustment with slow speed and low efficiency, so that the hole reservation device can be quickly installed and disassembled, thereby improving the reservation efficiency of reserved holes in building engineering.

[0041] The above description is only the preferred embodiment of the present application and the description of the technical principle and other solutions used. At the same time, the scope of the utility model involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features. It should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept of the utility model.
