[0005] The first mounting mechanism includes a first clamping plate and a first auxiliary plate. The first clamping plate has a groove inside, and insertion holes are symmetrically arranged on both sides of the groove. A connection hole is provided on one side of each insertion hole. The first auxiliary plate is arranged inside the first clamping plate. The first auxiliary plate has a through hole inside, and adjustment holes are provided on both sides of the first auxiliary plate. An anti-detachment block is provided on one side of each adjustment hole. A fixing rod is arranged inside each adjustment hole, and the fixing rod is installed on the first auxiliary plate.
[0006] The second mounting mechanism includes a second clamping plate and a second additional plate. The second additional plate is provided inside the second clamping plate. The second additional plate is exactly the same in structure and size as the first additional plate. A protrusion is provided at the bottom of the second clamping plate. Slide grooves are provided on both sides of the second clamping plate. A spring is provided inside the slide groove. An insert is provided inside the slide groove. The insert is L-shaped and penetrates one side surface of the second clamping plate.
[0007] The two ends of the threaded rod pass through corresponding through holes to connect and fix the first additional plate and / or the second additional plate.
[0008] In the above-mentioned assembly device, nuts are installed at both ends of the threaded rod, and the nuts are located on the side of the first additional plate and / or the second additional plate facing away from the irregular column.
[0009] In the above-mentioned assembly device, a sliding sleeve is fitted on the threaded rod, and a vertical sleeve is provided on the sliding sleeve. Vertical rods are installed in the upper and lower sets of vertical sleeves, and a laser rangefinder is slidably installed on the vertical rod. The laser rangefinder is suitable for measuring the distance from any point on the vertical rod to the surface of the irregular column.
[0010] In the above-mentioned assembly device, the first and second additional plates are provided with horizontal guides on the side opposite to the irregular column. Flatness auxiliary structures are installed in the upper and lower sets of horizontal guides. The flatness auxiliary structures include a sliding body one, a sliding body two, and two symmetrically arranged support rods. The top of the two support rods is hinged to the sliding body one, and the bottom is hinged to the sliding body two. The sliding body one and the sliding body two are respectively movably installed in the corresponding horizontal guides.
[0011] In the above-mentioned assembly device, the horizontal guide is provided with a vertical connecting hole, and an adjusting rod is installed in the vertical connecting hole. The adjusting rod includes a vertical section, a horizontal section, and a transition section connecting the horizontal section and the vertical section. Nuts are threadedly connected to the horizontal section and the vertical section, and the threaded rod passes through the horizontal section.
[0012] In the above-mentioned assembly device, the first additional plate is T-shaped, there are multiple adjustment holes, the adjustment holes are equidistant, and the fixing rod passes through the first clamping plate and is adapted and fixed to the corresponding adjustment hole.
[0013] In the above-mentioned assembly device, a rotating rod is provided at the connection between the protrusion and the groove.
[0014] A construction method for irregularly shaped columns in large stadiums, using the assembly device described above, includes the following steps:
[0015] Adjust according to the shape of the irregular column. When the irregular column is cross-shaped, press the insert block to compress the spring, so that the insert block slides inside the slide groove and retracts into the inside of the second clamping plate. Then, rotate the first clamping plate and the second clamping plate around the rotating rod so that the included angle between the first clamping plate and the second clamping plate is adjusted to 90 degrees. Then, release the insert block to allow the spring to rebound, so that the insert block slides inside the slide groove and fixes the insert block to the insertion hole. Next, adjust the fixing rod to loosen the fixation of the first and second auxiliary plates, adjust the extension length of the first and second auxiliary plates, and then fix and lock their length again by the fixing rod.
[0016] When the irregular column is T-shaped, the insert block is pressed to compress the spring, causing the insert block to slide inside the groove and retract into the second clamping plate. Then, the first and second clamping plates are rotated around the rotating rod to adjust the angle between the first and second clamping plates to 180 degrees. Then, the insert block is released, allowing the spring to return and the insert block to slide inside the groove, fixing the insert block to the connecting hole. Next, the fixing rod is rotated to loosen the fixing of the first and second auxiliary plates, thereby adjusting the combined length of the first auxiliary plate and the first and second auxiliary plates.
[0017] Installation of the lower-level assembly and fixing device:
[0018] A sliding sleeve is pre-installed on the threaded rod, and a vertical rod is installed in the vertical sleeve on the sliding sleeve. A laser rangefinder is installed on the vertical rod. The threaded rod passes through the through hole on the corresponding auxiliary plate and is installed with a nut. The nut is located on the outside of the auxiliary plate. The two auxiliary plates are pressed from the outside by the nut. The auxiliary plates are pressed against the surface of the main column located on the side of the irregular column.
[0019] Installation of the upper assembly and fixing device:
[0020] Two sliding bodies are installed on the horizontal guide of the lower auxiliary plate, and sliding body one is installed on the horizontal guide of the upper auxiliary plate. A sliding sleeve is pre-fitted on the threaded rod. The vertical sleeve on the sliding sleeve is inserted into the outside of the lower vertical rod. The threaded rod passes through the through hole on the corresponding auxiliary plate and connects the nut. The nut is located on the outside of the auxiliary plate.
[0021] Support rods are installed on the sliding body 2. The tops of the two support rods are hinged to the sliding body 1 to ensure the flatness of the upper and lower additional plates. The two additional plates are pressed from the outside by adjusting the nuts on the threaded rods. The additional plates are pressed against the surface of the main column located on the side of the irregular column.
[0022] An adjusting rod is installed on the upper and lower threaded rods. The horizontal section of the adjusting rod passes through the threaded rod and is fitted with a nut, while the vertical section passes through the vertical connecting hole on the horizontal guide and is fitted with a nut.
[0023] Adjusting the verticality of the main column of the irregularly shaped column:
[0024] The distance from any point on the vertical member to the surface of the irregular column is measured by sliding the laser rangefinder up and down. By adjusting the nuts on the horizontal sections of the adjusting rods of the upper and lower layers, the threaded rod is moved horizontally relative to the additional plate to adjust the verticality of the irregular column located on the side main column. Push cylinders are installed on the outer side of the main column in the middle. There are at least two sets of push cylinders arranged vertically, with four cylinders in each set, which are installed on the outer wall of the main column in the middle. By adjusting the piston rod of the push cylinder, the center position of the main column in the middle is determined, ensuring that the main columns on the side are distributed in a cross shape with the main column in the middle.
[0025] Irregular column assembly:
[0026] The main columns of the irregular column are assembled into a whole by prefabricated standard parts. The prefabricated standard parts are first installed in the area between the two sets of jacking cylinders. After the jacking cylinders are removed, the prefabricated standard parts in their positions are installed. The main columns located on the side and in the middle are connected and fixed by the prefabricated standard parts.
[0027] The beneficial effects of this invention are as follows:
[0028] This invention uses a protrusion and a groove, rotates around a rotating rod, and then releases the insert to allow the spring to return, causing the insert to slide inside the groove and fix the insert to the insertion hole. This allows adjustment of the combined length of the first additional plate and the first clamping plate, as well as the second additional plate and the second clamping plate, so that the device can adapt to the length and shape of different irregular columns, thus enhancing the adaptability of the device.

The through holes 23 are rectangular holes, and the threaded rod 3 slides horizontally relative to the first auxiliary plate 22 and / or the second auxiliary plate 211 in the through holes 23.
[0044] Nuts are installed at both ends of the threaded rod 3, and the nuts are located on the side of the first additional plate 22 and / or the second additional plate 211 facing away from the irregular column 1.
[0045] A sliding sleeve 31 is fitted on the threaded rod 3. A vertical sleeve 32 is provided on the sliding sleeve 31. Vertical rods 33 are installed in the upper and lower sets of vertical sleeves 32. A laser rangefinder 34 is slidably installed on the vertical rods 33.

[0046] The first additional plate 22 and the second additional plate 211 are provided with horizontal guides 216 on the side opposite to the irregular column 1. Flatness auxiliary structures are installed in the upper and lower sets of horizontal guides 216. The flatness auxiliary structures include a sliding body 1 217, a sliding body 218 and two symmetrically arranged support rods 219.

[0049] A construction method for irregularly shaped columns in large stadiums, comprising the following steps:
[0050] Preparation:
[0051] Adjust according to the shape of the irregular column 1. When the irregular column 1 is cross-shaped, press the insert 215 to compress the spring 214, so that the insert 215 slides inside the slide groove 213 and retracts the insert 215 into the second clamping plate 210. Then, rotate the first clamping plate 21 and the second clamping plate 210 around the rotating rod so that the included angle of the first clamping plate 21 and the second clamping plate 210 is adjusted to ninety degrees. Then, release the insert 215 to allow the spring 214 to rebound, so that the insert 215 slides inside the slide groove 213 and fixes the insert 215 to the insertion hole 27. Then, adjust the fixing rod 29 to loosen the fixation of the first auxiliary plate 22 and the second auxiliary plate 211, adjust the outward extension length of the first auxiliary plate 22 and the second auxiliary plate 211, and re-fix and lock their length by the fixing rod 29.
[0052] When the irregular column 1 is T-shaped, the insert 215 is pressed to compress the spring 214, causing the insert 215 to slide inside the slide groove 213, allowing the insert 215 to retract into the interior of the second clamping plate 210. Then, the first clamping plate 21 and the second clamping plate 210 are rotated around the rotating rod, so that the included angle between the first clamping plate 21 and the second clamping plate 210 is adjusted to 180 degrees. Then, the insert 215 is released, allowing the spring 214 to rebound, causing the insert 215 to slide inside the slide groove 213, and fixing the insert 215 to the connecting hole 28. Then, the fixing rod 29 is rotated to loosen the fixing of the first auxiliary plate 22 and the second auxiliary plate 211, thereby adjusting the combined length of the first auxiliary plate 22 and the first clamping plate 21, the second auxiliary plate 211 and the second clamping plate 210 respectively.
[0053] In summary, this invention utilizes protrusions and grooves, rotates around a rotating rod, and then releases the insert block to allow the spring to return, causing the insert block to slide inside the groove and fix itself to the insertion hole. This allows adjustment of the combined lengths of the first additional plate and the first clamping plate, as well as the second additional plate and the second clamping plate, enabling the device to adapt to different irregular column lengths and shapes, thus enhancing the device's adaptability.

[0061] Adjustment of the verticality of the main column of irregular column 1:
[0062] The distance from any point on the vertical rod 33 to the surface of the irregular column 1 is measured by sliding the laser rangefinder 34 up and down. The threaded rod 3 moves horizontally relative to the auxiliary plate by adjusting the nuts on the horizontal section of the adjusting rod 2110 of the upper and lower layers, thereby adjusting the verticality of the irregular column 1 located on the side main column. Push cylinders are installed on the outer side of the main column in the middle. There are at least two sets of push cylinders arranged vertically, with four cylinders in each set, which are installed on the outer wall of the main column in the middle.

After the push cylinders are removed, the prefabricated standard parts in their positions are installed. The main columns located on the side and in the middle are connected and fixed by the prefabricated standard parts.

By adjusting the nuts on the horizontal section of the adjusting rod (2110) of the upper and lower layers, the threaded rod (3) is driven to move horizontally relative to the additional plate, and the verticality of the irregular column (1) located on the side main column is adjusted. Push cylinders (35) are installed on the outside of the main column in the middle. The push cylinders (35) are provided with at least two sets arranged vertically, four in each set, which are installed on the outer wall of the main column in the middle. By adjusting the piston rod of the push cylinder (35), the position of the main column in the middle is determined to be the center position of the four side main columns, and the main columns located on the side are arranged in a cross shape with the main column in the middle. Assembly of irregular column (1): The main columns of the irregular column (1) are assembled into a whole by prefabricated standard parts. The prefabricated standard parts are first installed in the area between the two sets of push cylinders (35). After the push cylinders (35) are removed, the prefabricated standard parts in their positions are installed. The main columns located on the side and in the middle are connected and fixed by the prefabricated standard parts.
