[0019] Finally, the two ends of the lattice column leveling inner frame are also provided with the same buckle device, and the buckle devices at the two ends of the lattice column leveling inner frame in the first connection part and the second connection part are correspondingly installed and fixed.

[0020] The utility model aims to solve the problem that the length of the side of the column pile is difficult to keep level with the center line of the pile position during the center positioning and lowering process. The auxiliary device can maximize the determination of the center position and the level of the length of the lattice column with the center line of the pile position during the lowering process. The device is easy to use, time-saving, does not require excessive material preparation before operation, and uses the remaining steel bars on site for processing. The size of the device is adjusted and changed according to the on-site construction. It is less affected by external factors and can effectively ensure the accuracy of the center of the column pile and the parallelism of the length of the lattice column with the center line of the pile position.

[0021] The technical solution of the utility model to achieve the above purpose is as follows:

[0022] A column pile positioning and lowering auxiliary device, the device is composed of three parts;

[0023] The first part of the structure is connected as a whole by the center positioning outer frame 2 and the lattice column leveling inner frame 1 through the steel bar diagonal rod 3. The left end of the center positioning outer frame 2 is provided with a snap device 4, and the right end is vertically connected to the steel bar cross bar 6. Two fixed legs 5 are vertically perpendicular to the two ends of the center positioning outer frame 2, and are fixed to the casing with the center positioning outer frame 2 to determine the accuracy of the pile position center and the casing center; two snap devices 4 are also provided at both ends of the lattice column leveling inner frame 1, which are used to make the first part of the structure and the second part of the structure more stable and firm when the auxiliary device is in the working state.

[0024] The structure of the second part is similar to that of the first part.

[0025] The third part of the structure is the connector, see the detailed node diagram Figure 2 The detailed node diagram of the connecting piece is the connecting piece between the first part structure and the second part structure, which enables them to rotate on the same horizontal plane.

[0026] The working process of the utility model is as follows:

[0027] Step 1: First place the center line of the pile position and mark fixed points around the casing. Mark both ends of the casing by coinciding the center line with the casing at two points.

[0028] Step 2: When the steel cage is lowered to the bottom of the casing, the lattice column will continue to be lowered. At the same time, the auxiliary device will be opened, and the first part of the structure will be connected to the lattice column and placed 1 meter above the casing. Then the auxiliary device will be closed, and the steel bar cross bars 6 at both ends of the first and second parts of the structure will be adjusted to be level with the center line just above the marking point of the casing.

[0029] Step 3: During the continuous lowering process, the fixed legs 5 at the four ends of the center positioning outer frame 2 are placed inside the casing. When the auxiliary device is lowered onto the casing, the four fixed legs 5 are ensured to be on the inside of the casing to determine the accuracy of the pile center and the casing center. The steel bar cross bars 6 at both ends of the first and second parts of the structure coincide with the marking points at both ends of the casing, and the side length of the lattice column is adjusted to be level with the center line.

[0030] As mentioned above, although the present invention has been represented and described with reference to specific preferred embodiments, it should not be interpreted as a limitation of the present invention itself. Various changes in form and details may be made without departing from the spirit and scope of the present invention defined in the appended claims.
