[0014] Implementing the embodiments of the present invention has the following beneficial effects: 1. This scheme adopts an openable and closable positioning cover structure installed on the steel casing. The steel casing is vertically installed at the opening of the column pile hole. The openable and closable positioning cover includes a protective cover plate and a fixed angle iron. The fixed angle iron is connected to the steel casing. The protective cover plate is provided with a diagonal limit opening and the protective cover plate is movably connected to the fixed angle iron. The diagonal positioning hangers on the lattice column are clamped diagonally by the diagonal limit opening to limit the position, which solves the problem that the top of the lattice column cannot be limited below the steel casing, thereby affecting the lowering accuracy of the lattice column, and achieves the effect of improving construction quality and saving adjustment time.
[0015] 2. This scheme adopts the construction technology of welding water-stop steel plate in advance, installing thick extruded plate, and welding diagonal positioning hangers. The steel casing is installed on the ground in advance, and the top of the lattice column installed with water-stop steel plate and thick extruded plate is hooked by crawler hook and lowered to the mouth of the steel casing. Then the diagonal positioning hangers are welded, and then the retractable positioning cover is installed. The diagonal positioning hangers are limited by the protective cover plate, and the protective cover plate is supported by the fixed angle iron. When the lattice column is lowered below the steel casing, the position will not be offset, ensuring that the lattice column is finally installed in the center of the steel cage, solving the difficulties in positioning control during the lowering of the lattice column and the difficulty of post-welding of the water-stop steel plate. The work quality is difficult to control and there are problems with the positioning of the lattice column when it is lowered. Because the welding height of the water-stop steel plate of the lattice column is calculated in advance before welding, the thick extruded plate is installed on the upper and lower sides of the water-stop steel plate. When pouring concrete, the concrete on the inside and outside of the over-filled part is separated by the isolation of the thick extruded plate, and the internal extruded plate and the over-filled concrete block can be quickly chiseled out, which simplifies the positioning control during the lowering of the lattice column, quickly chisels out the over-filled part of the concrete, improves the quality of the water-stop steel plate welding, realizes the precise positioning of the top of the lattice column below the steel casing, and improves the overall construction efficiency and the construction quality of the column piles.
[0016] 3. The openable and closable positioning cover of this scheme adopts a double locking design. The openable and closable positioning cover includes a protective cover plate and a fixed angle iron. The protective cover plate is fixedly connected to the fixed angle iron. The first cover plate and the second cover plate on the protective cover plate are respectively connected to the left angle iron and the right angle iron. The left angle iron and the right angle iron are respectively provided with fastening bolt holes. The fixed angle iron is locked to the steel casing by fastening bolts. The fixing device includes a fixed latch, a latch sleeve 1 and a latch sleeve 2. The latch sleeve 1 and the latch sleeve 2 are respectively fixedly connected to the first cover plate and the second cover plate. The opening and locking of the protective cover plate are achieved by locking the fixed latch into the latch sleeve 1 and the latch sleeve 2, so that the openable and closable positioning cover is not easy to shake during the lowering of the lattice column, thereby achieving the effect of accurately positioning the top of the lattice column below the steel casing and enhancing the structural stability.

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0020] like Figures 1 to 13 As shown, an embodiment of the present invention provides a lattice column positioning structure, comprising: A lattice column 5, wherein the lattice column 5 is welded with a diagonal positioning hanger 6; a steel casing 1, wherein the steel casing 1 is vertically installed on the ground to preliminarily position the lattice column 5; an openable and closable positioning cover 2, wherein the openable and closable positioning cover 2 is connected to the steel casing 1, and the openable and closable positioning cover 2 comprises a protective cover plate 21 and a fixed angle iron 22, wherein the fixed angle iron 22 is movably connected to the steel casing 1, and the protective cover plate 21 is provided with a diagonal limiting opening 211 and the protective cover plate 21 is connected to the fixed angle iron 22; the lattice column 5 clamps the diagonal positioning hanger 6 through the diagonal limiting opening 211 to realize the limiting adjustment of the lattice column 5.
[0021] Specifically, the protective cover plate 21 is fixedly connected to the fixed angle iron 22, and the protective cover plate 21 is provided with a first cover plate 212, a second cover plate 213, an opening and closing hinge 214, and a fixing device 215. The first cover plate 212 and the second cover plate 213 are relatively installed through the opening and closing hinge 214, and the first cover plate 212 and the second cover plate 213 can rotate relative to each other. The fixing device 215 can fix the first cover plate 212 and the second cover plate 213. Such a design can enable the protective cover plate 21 to evenly distribute pressure through the relatively arranged first cover plate 212 and the second cover plate 213 when limiting the lattice column 5, thereby avoiding deformation or damage caused by uneven pressure when the diagonal positioning hanger 6 is lowered.
[0022] Furthermore, the length of the diagonal limit opening 211 is 50 mm greater than the length of the lattice column 5, and the width of the diagonal limit opening 211 is 50 mm greater than the width of the lattice column 5, so as to ensure that the diagonal limit opening 211 best limits the diagonal positioning hanger 6 of the lattice column 5; The diagonal limit opening 211 is formed by the first cover plate 212 and the second cover plate 213 being placed relative to each other, so that the protective cover plate 21 can quickly clamp the diagonal positioning hanging rod 6 and facilitate the adjustment of the diagonal orientation, saving the installation and adjustment time of the protective cover plate 21. At the same time, the double-plate design can enable the diagonal of the diagonal limit opening 211 to better clamp the diagonal positioning hanging rod 6, enhance the stability of the structure, and avoid shaking during the lowering process.
[0023] Furthermore, the fixing device 215 includes a fixed latch 2151, a latch sleeve 1 2152, and a latch sleeve 2153. The latch sleeve 1 2152 is fixedly welded to the first cover plate 212, and the latch sleeve 2153 is fixedly welded to the second cover plate 213. The fixed latch 2151 can be inserted into the latch sleeve 1 2152 and the latch sleeve 2153 to fix the protective cover plate 21. The fixed latch 2151 is used for connection, and the latch sleeve 1 2152 and the latch sleeve 2 2153 are quickly connected or disconnected by inserting and pulling out the fixed latch 2151. The cooperation between the latch and the sleeve can be designed to be very precise, making the connection more reliable and reducing safety accidents caused by accidental loosening. Moreover, the connection between the latch and the sleeve is easy to disassemble and can save the installation and removal time of the openable and closable positioning cover 2, thereby greatly improving the construction efficiency.
[0024] Furthermore, the fixed angle iron 22 is L-shaped and circular in design, the upper part is used to install the protective cover plate 21, and the lower part is used to abut against the steel casing 1. The fixed angle iron 22 is provided with a left angle iron 221, a right angle iron 222, a fastening bolt 223, and a fastening bolt hole 224 is opened at the lower part of the fixed angle iron 22. The first cover plate 212 is fixedly connected to the left angle 221, and the second cover plate 213 is fixedly connected to the right angle iron 222. The left angle iron 221 and the right angle iron 222 are rotatably connected to the opening and closing hinge 214, so that the left angle iron 221 and the right angle iron 222 can rotate relative to each other. The fastening bolt 223 can be installed in the fastening bolt hole 224 and abut against the steel casing 1 to stabilize the fixed angle iron 22. With this design, the fixed angle iron 22 can better abut against the steel casing 1, providing safe support and fixation for the protective cover plate 21.
[0025] Furthermore, the fastening bolt holes 224 are symmetrically arranged on the left angle iron 221 and the right angle iron 222 so that the fixed angle iron 22 is evenly stressed. The symmetrical design of the fastening bolt holes 224 can evenly distribute the load and reduce the stress and deformation caused by asymmetric load. At the same time, the even distribution of the load can reduce the vibration and swing of the structure, which helps to improve the stability of the structure.
[0026] Furthermore, the lattice column positioning structure provided in the embodiment of the present utility model also includes a shaped adjustable limiting device 7, wherein the shaped adjustable limiting device 7 is provided with a shaped adjustable limiting support frame 71 and a shaped adjustable limiting movable rod 72, and a plurality of the shaped adjustable limiting movable rods 72 are detachably connected to the shaped adjustable limiting support frame 71 for limiting; in the embodiment of the present invention, the adjustable limiting support frame 71 preferably adopts a square structural design, and the shaped adjustable limiting support frame 71 is provided with a shaped adjustable limiting connecting rod 711 and a shaped adjustable limiting supporting rod 712, and a plurality of the shaped adjustable limiting supporting connecting rods 711 and 712 are provided.

The limit moving rod adjusting bolt 722 is connected to the limit moving rod fixing nut 721 and extends into the limit moving rod C-shaped sliding groove 723; the limit moving rod C-shaped sliding groove 723 is slidably connected to the shaped adjustable limit link 711, and abuts against the shaped adjustable limit link 711 through the limit moving rod adjusting bolt 722, so as to fix the shaped adjustable limit moving rod 72 on the shaped adjustable limit support frame 71, thereby ensuring the reliability of adjustment of the shaped adjustable limit device 7; the shaped adjustable limit link 711 and the shaped adjustable limit support rod 712 are both made of angle iron, which is convenient for welding, and at the same time, the shaped adjustable limit support frame 71 has very high strength and load-bearing capacity, and can withstand large weight and pressure, thereby ensuring stability during the adjustment process.
[0027] Furthermore, in order to solve the problem that the construction quality of the post-welding of the waterstop steel plate 3 is difficult to control, the lattice column 5 is also pre-welded with the waterstop steel plate 3 to ensure that the welding of the waterstop steel plate 3 is firm and the position is accurate; 4 L-shaped thick extruded plates 4 with a height of 25 cm and a thickness of 5 cm are installed on the upper and lower sides of the waterstop steel plate 3 and wrap the lattice column 5. The thick extruded plates 4 can separate the concrete on the inside and outside sides of the over-filled part of the lattice column so that the over-filled part of the concrete can be quickly chiseled out after the concrete solidifies.
[0028] Furthermore, the diagonal limit opening 211 is designed to be square so that the diagonals of the diagonal limit opening 211 can clamp the diagonal positioning hanger 6 for limiting. The square design enables both diagonals of the diagonal limit opening 211 to limit the diagonal positioning hanger 6, thereby saving the installation time of the protective cover plate 21 and improving construction efficiency.
[0029] The present invention also provides a lattice column forming process, which uses the lattice column positioning structure as described above to assist in forming, and includes the following steps: a. Pre-welding of the lattice column 5, including welding of the overall structure of the lattice column 5, calculation of the welding height of the water-stop steel plate 3 of the lattice column 5, and welding of the water-stop steel plate 3; b. Installation of thick extruded boards 4: 8 L-shaped thick extruded boards 4 with a height of 25 cm and a thickness of 5 cm are fixedly installed on the upper and lower sides of the water-stop steel plate 3 and the lattice columns 5 are wrapped with the thick extruded boards 4; c. Preliminary positioning: vertically install the steel casing 1 at the opening of the column pile hole and make the opening of the steel casing 1 level with the opening of the column pile hole, install the fixed adjustable limit device 7, adjust the fixed adjustable limit moving rod 72 on the fixed adjustable limit device 7 to surround the fixed limit opening for the steel cage 8 to pass through, and lower the steel cage 8 until the upper end of the steel cage 8 is level with the opening of the steel casing 1; the construction personnel hook the lattice column 5 installed with the water-stop steel plate 3 and the thick extruded board 4 through the crawler hook and lower it, after the lattice column 5 installed with the water-stop steel plate 3 and one end of the thick extruded board 4 enters the steel cage 8, adjust the fixed adjustable limit moving rod 72 to surround the fixed limit opening for the lattice column 5 to pass through, and then lower the top of the lattice column 5 to the opening of the steel casing 1, adjust the top of the lattice column 5 to be level with the opening of the steel casing 1, so as to ensure that the lattice column 5 remains level when lowered; d. Welding of diagonal positioning hangers 6: After the lattice column 5 is initially positioned, diagonal positioning hangers 6 are welded at the diagonals of the lattice column 5 to ensure that the position of the lattice column 5 is horizontal and easy to position; e.

The over-filled part is quickly chiseled out, and after confirming that there is no abnormality in the position of the lattice column 5, the concrete pouring operation is carried out. When pouring concrete, the concrete on both sides of the over-filled part is separated by the thick extruded board 4.

After cleaning, the detachable reinforcing plate 51 of the lattice column is connected to the lattice column 5 through a threaded connector to improve the stability of the lattice column 5 during use.

Preliminary positioning: vertically install the steel casing (1) at the opening of the column pile hole, install the adjustable stopper (7), adjust the installation adjustable stopper (7), lower the steel cage (8) to the opening of the steel casing (1), and then hook the top of the lattice column (5) installed with the water-stop steel plate (3) and the thick extruded plate (4) through the crawler hook and lower it to the opening of the steel casing (1), and adjust the top of the lattice column (5) to be level with the opening of the steel casing (1); d. Welding of diagonal positioning hangers (6), after the lattice column (5) is initially positioned, diagonal positioning hangers (6) are welded at the diagonals of the lattice column (5); e. Installing the fixed angle iron (22), fixing the fixed angle iron (22) on the steel casing (1), and locking the left angle iron (221) and the right angle iron (222) by means of the fastening bolts (223); f. Install the protective cover plate (21), clamp the diagonal of the diagonal limit opening (211) of the protective cover plate (21) to the diagonal positioning hanger (6) on the lattice column (5), then clamp the fixing pin (2151) into the pin sleeve 1 (2152) and the pin sleeve 2 (2153) to fix the protective cover plate (21), and then lower the lattice column (5) to the bottom of the pile hole; g. The over-filled part is quickly chiseled out. When pouring concrete, the concrete on both sides of the over-filled part is separated by the thick extruded plate (4). After the concrete solidifies, the over-filled concrete on the outer side is chiseled out, and then the detachable reinforcing plate (51) of the lattice column is removed, and the internal thick extruded plate (4) and the over-filled concrete block on the inner side can be quickly chiseled out.
