[0002] The cast-in-place pile is a commonly used pile type in building foundation engineering. By pouring concrete or reinforced concrete materials into the pre-drilled pile holes on the ground, a solid pile body that supports the building foundation is formed.

[0003] The steel reinforcement cage is a cage-like structure welded or tied with steel bars. It is usually used in the construction of cast-in-place piles and placed in the pile holes, and then concrete is poured to form a reinforced concrete pile. The steel reinforcement cage can effectively enhance the compressive, flexural and shear resistance of the pile body, improve the bearing capacity of the pile; it can disperse the stress in the concrete, prevent the concrete from cracking; it can ensure the uniform distribution of the concrete in the pile hole, avoid the occurrence of cavities or honeycombing phenomena, and ensure the quality of the pile body. During the construction management process, it has always been emphasized that the positioning of the main reinforcement bars of the steel reinforcement cage should be accurate and the welding between the main reinforcement bars and the stiffening rings needs to be precise. However, since there is often no corresponding auxiliary device for the welding between the main reinforcement bars and the stiffening rings, the positioning deviation of the main reinforcement bars of the steel reinforcement cage and the welding position accuracy between the main reinforcement bars and the stiffening rings cannot be guaranteed, thus generating great potential quality risks in the later stage.

[0023] In this embodiment, the telescopic rod assembly 3 includes a telescopic rod that can be telescopically positioned, a positioning guide head 32 connected to the end of the telescopic rod, and a positioning wing plate 31 provided at the end of the telescopic rod; a disc radial hole 11 for installing the positioning guide head 32 in cooperation is opened on the positioning disc 1. The telescopic rod (an existing telescopic rod that can be telescopically positioned and adjusted can be used) can be telescopically adjusted to facilitate positioning and installation on positioning discs 1 of different sizes. A positioning guide head 32 structure is provided at the end of the telescopic rod for inserting and installing in cooperation with the disc radial hole 11 opened on the positioning disc 1. After the positioning guide head 32 is inserted and positioned, it is fixedly installed in cooperation with the inner surface of the positioning disc 1 through the positioning wing plate 31 to ensure the stable and reliable installation of the overall structure.

[0024] In this embodiment, the positioning guide head 32 is integrally in a conical structure, and a limiting ring 33 is sleeved outside the positioning guide head 32, and a plurality of the limiting rings 33 are evenly distributed along the length direction of the positioning guide head. As Figure 2As shown, the positioning guide head 32 is integrally conical. A limiting ring 33 structure is sleeved outside the conical section of the positioning guide head 32. Correspondingly, the disk radial hole 11 is opened into a matching conical structure to facilitate the alignment and insertion of the positioning guide head 32. The limiting ring 33 is made of a material with certain elasticity and multiple limiting rings 33 are provided. After the limiting ring 33 is inserted into the corresponding disk radial hole 11, an effective limiting effect can be formed, making the overall structure more stable and reliable in installation.

[0025] In this embodiment, the positioning wing plate 31 is sleeved on the end of the telescopic rod and abuts against the end face of the positioning guide head 32. The end of the positioning wing plate 31 extends outward to form an arc-shaped fitting part, and a wing plate opening for cooperating with the positioning disk for locking installation is opened on the arc-shaped fitting part. The positioning wing plate 31 is fixedly sleeved and installed at the end of the positioning guide head 32, and the positioning wing plate 31 fits against the end face position of the positioning guide head 32. The two ends of the positioning wing plate 31 extend outward (i.e., along the radial direction of the telescopic rod) respectively to form an arc-shaped fitting part for cooperating with the positioning disk 1 for positioning installation, and a wing plate opening is opened on the arc-shaped fitting part for cooperating with the inner surface of the positioning disk for positioning and locking installation. The inner surface of the positioning disk 1 is correspondingly provided with an inner surface opening for cooperating with the wing plate opening. The arc-shaped fitting part can be made of a metal sheet or elastic material with certain elasticity. The wing plate opening is correspondingly set as a strip-shaped hole structure. When the positioning guide head 32 is inserted into the disk radial hole 11, the arc-shaped fitting part fits against the inner surface of the positioning disk 1, and a locking bolt passes through the wing plate opening and is locked in the inner surface opening to ensure the installation stability of the telescopic rod assembly 3.

[0026] In this embodiment, there are multiple telescopic rods 3, and the multiple telescopic rods 3 are evenly distributed along the same circumferential direction. The positioning disk 1 is provided with multiple disk radial holes 11 for cooperating with the telescopic rods. The telescopic rods 3 can be set to three. Correspondingly, there are three disk radial holes 11, and the three disk radial holes 11 are evenly distributed on the positioning disk 1. The ends of the three telescopic rods 3 are hinged and installed with the indexing rod 4 to ensure the stability when the indexing rod 4 rotates and adjusts.

[0027] In this embodiment, the indexing handle assembly includes an indexing rod 4 hinged and installed with the telescopic rod 3 and a positioning press block member 5 installed in cooperation with the indexing rod 4. A positioning slot 41 is opened in the middle of the indexing rod. The positioning press block member 5 can be slidably adjusted and installed in the positioning slot 41. The end of the indexing rod 4 is hinged and installed with the telescopic rod 3. A positioning slot 41 for slidably adjusting and installing the positioning press block member 5 is provided in the middle of the indexing rod. After the indexing rod 4 rotates, the positioning press block member 5 rotates synchronously. After rotating to a suitable position, the positioning press block member 5 cooperates with the positioning disk 1 for positioning installation.

[0028] In this embodiment, the positioning press block member 5 includes a left press block body 51, a press block slider 53 provided at the lower end of the left press block body, a right press block body 52 slidably installed in cooperation with the left press block body 51, and a press block positioning column 54 installed at the lower end of the right press block body. A plurality of circumferential holes of the disc are evenly distributed in the circumferential direction of the positioning disc, and the press block positioning column is inserted into the circumferential holes of the disc for positioning installation. A press block slider 53 is fixedly installed at the lower end of the left press block body. The press block slider 53 has an inverted T-shaped structure for slidably installing in cooperation with the positioning slot 41. A press block positioning column 54 is fixedly connected and installed at the lower end of the right press block body. A plurality of circumferential holes of the disc are evenly distributed along the circumferential direction of the positioning disc 1. When the positioning press block member 5 rotates to a suitable angle, the press block positioning column 54 at the lower end of the right press block body is inserted into the circumferential holes of the disc to form a stable positioning installation position.

[0029] In this embodiment, a press block guide groove 511 is provided on the left press block body 51, and a press block convex block 522 for cooperating with the press block guide groove is formed on the right press block body 52. There are two press block convex blocks 522, and the two press block convex blocks 522 are arranged in parallel. The structures of the press block guide groove 511 and the press block convex block 522 are respectively provided between the left press block body 51 and the right press block body 52, facilitating the sliding adjustment between the two (along Figure 3 the vertical direction shown). There are two press block convex blocks 522, and correspondingly there are also two press block guide grooves 511, ensuring the stability of the overall structure during their sliding adjustment. Of course, the stroke distance of their sliding adjustment can be correspondingly limited according to actual use.

[0030] In this embodiment, an elastic pad 55 is provided at the end of the press block positioning column 54. An outer guide groove 12 of the disc for cooperating with the stiffening hoop installation is provided on the outer circumference of the positioning disc 1. The length of the indexing rod 4 is greater than the radius of the positioning disc. The elastic pad 55 structure is provided at the lower end of the press block positioning column 54, and the diameter of the elastic pad 55 is slightly larger than the opening diameter of the circumferential hole of the disc. When the positioning press block member 5 rotates above the circumferential hole of the disc, the right press block body 52 is pressed down so that the press block positioning column 54 is installed in the circumferential hole of the disc. The elastic pad 55 can improve the stability after installation. The outer guide groove 12 structure formed on the surface of the positioning disc 1 facilitates the positioning installation of the stiffening hoop. The length of the indexing rod 4 is greater than the radius of the positioning disc 1, facilitating the rotation adjustment during use.

[0031] A construction method of a welding positioning device for the main reinforcement bars and stiffening hoops of a steel reinforcement cage includes the following steps:

[0032] S1: Select the corresponding positioning disc 1 according to the size of the steel reinforcement cage to be constructed, manufacture the stiffening hoop 2 and install it outside the positioning disc 1 in cooperation; according to the use size of the steel reinforcement cage, select the positioning disc 1 with the corresponding specification radius, and manufacture the stiffening hoop 2 and install it on the positioning disc 1;

[0033] S2: Install the multiple positioning and guiding heads of the telescopic rod assembly 3 in the radial holes 11 of the disc in a telescopic and adjustable manner respectively. After adjusting the positioning wing plate to fit the inner surface of the positioning disc, use bolts to cooperate with the positioning disc for positioning and locking; adjust the length of the telescopic rod assembly, insert the positioning and guiding head 32 of the telescopic rod assembly into the interior of the radial hole 11 of the disc, adjust the arc-shaped fitting part at the end of the positioning wing plate 31 to fit the inner surface of the positioning disc 1, and pass the locking bolt through the strip-shaped opening of the arc-shaped fitting part and lock it to the inner surface opening of the positioning disc 1 to ensure the stable and reliable installation of the telescopic rod assembly;

[0034] S3: Rotate the indexing handle 4 around the positioning disc 1 for one circle to ensure that the indexing handle can rotate normally. Adjust the positioning press block member 5 to a suitable position in the positioning slot 41, and press the right press block body 52 so that the press block positioning column 54 cooperates with the circumferential hole of the disc of the positioning disc for positioning and installation; slide the positioning press block member 5 to a suitable radial position, rotate the indexing handle 4 so that the positioning press block member 5 is directly above the circumferential hole of the disc, and press down the right press block body 52 to install the press block positioning column 54 into the circumferential hole of the disc to ensure the stable and reliable installation;

[0035] S4: Place the main reinforcement 6 between the indexing handle 4 and the stirrup 2, and perform single-sided welding on the main reinforcement 6 and the stirrup 2; after completing step S3, the welding position for welding the main reinforcement 6 is formed at the intersection position between the indexing handle 4 and the stirrup 2. As Figure 1 shown, perform single-sided welding on the main reinforcement 6 and the stirrup 2 (i.e., the right side position in the figure);

[0036] S5: Remove the adjusting positioning press block member to make the press block positioning column disengage from the circumferential hole of the disc. Rotate the indexing handle clockwise to the next hole position of the circumferential hole of the disc. After ensuring that the positioning column is reinstalled in place in cooperation with the circumferential hole of the disc, repeat step S4; after the first main reinforcement 6 is welded, remove the adjusting positioning press block member and rotate it clockwise to the next hole position (circumferential hole of the disc), perform pressing and repeat the previous single-sided welding treatment;

[0037] S6: After the indexing handle 4 rotates around the positioning disc 1 for one circle and the welding is completed, remove the main reinforcement welding positioning mechanism, and weld the other side of the main reinforcement and the stirrup one by one. After the indexing handle 4 performs positioning welding along the circumferential holes of the positioning disc 1 for one circle, take out the positioning disc 1 from the stirrup 2 (the depth of the outer guiding groove 12 of the disc is relatively shallow and does not affect the removal of the positioning disc 1 from the stirrup 2), and then weld the other side between the main reinforcement and the stirrup 2 to ensure that both the left and right sides where the main reinforcement contacts the stirrup 2 are welded in place.
