[0002] Steel formwork, as a tool used for concrete pouring and molding, is mainly made of steel. Compared with other types of formwork such as wooden formwork and plywood formwork, steel formwork has been widely used in the field of construction engineering due to its excellent durability, precise concrete pouring and molding effect and good appearance.

[0003] In the pouring operation of bridge piers, steel formwork is an indispensable tool. Since bridge piers usually contain complex curved surfaces, it is required to use specially designed curved steel formwork during the pouring process. The steel formwork structures currently on the market are as follows: Figure 1 As shown, it generally includes a plurality of main beams and ribs arranged on the surface of the template.

They first need to ensure that the main beam or rib plate fits tightly against the surface of the formwork, then temporarily fix its position using spot welding technology, and finally perform comprehensive welding. However, due to the special geometric shape of the arc formwork, workers spend a lot of time and energy in the alignment process, thereby reducing the overall work efficiency. For this reason, we propose a steel formwork welding mechanism and a welding method for pier casting. Summary of the invention

DETAILED DESCRIPTION

[0040] 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.

[0041] Example 1: Please refer to Figure 2-Figure 11 The present invention provides a technical solution: a steel formwork welding mechanism for pier casting, comprising a workbench 1, which is a solid metal structure to ensure that it can bear the weight of heavy equipment and a formwork body. A gantry 2 is slidably arranged on the workbench 1. The gantry 2 has a stable structure and moves on the workbench 1 through a sliding device to ensure operational flexibility. In addition, a limit plate 3 is fixedly arranged on the workbench 1. The limit plate 3 is precisely designed to ensure that the formwork body is in close contact with its side wall when placed, so that one side of the formwork body is kept vertical to the gantry 2, thereby ensuring accurate positioning.

[0042] A connecting frame 4 is slidably arranged on the gantry 2, and the connecting frame 4 can slide freely left and right on the gantry 2, which greatly increases the operating range of the welding head 7. An elastic support member 5 is slidably arranged on the connecting frame 4, and this design allows the welding head 7 to be flexibly adjusted in the vertical direction. A flexible track 6 is fixedly installed on the bottom end of the elastic support member 5. The use of the flexible track 6 enables the welding head 7 to fit the surface of the template with the help of the flexible track 6, thereby realizing mobile welding, which greatly improves the accuracy and efficiency of welding. During welding, the flexible track 6 can fit closely to the surface of the template, and guide the welding head 7 to perform mobile welding along its trajectory.

[0043] The connecting frame 4 includes a slide bar 41 slidably set on the gantry 2. The slide bar 41 slides left and right on the gantry 2 steadily and smoothly, ensuring the stability and continuity of the welding process. A fixed sleeve 42 is fixedly set at the bottom of the slide bar 41, and a connecting shaft 43 is movably set in the fixed sleeve 42. The design of the connecting shaft 43 allows the cross plate 44 to be adjusted in angle within a certain range. The end of the connecting shaft 43 is fixedly connected to the cross plate 44, and vertical slide rails 45 are fixedly set on both sides of the cross plate 44. The vertical slide rails 45 provide a stable up and down sliding track for the elastic support member 5.

[0044] The internal structure of the connecting shaft 43 is exquisite, and a cavity is provided therein, in which a connecting spring 46 is arranged, and a positioning block 47 is connected to the end of the connecting spring 46. At the same time, an electromagnet 48 is also arranged in the cavity, and the positioning block 47 is made of metal. When the electromagnet 48 is energized, it can attract the positioning block 47 and shrink it into the cavity, thereby unlocking the rotation function of the connecting shaft 43 in the fixed sleeve 42. The outer side of the fixed sleeve 42 is provided with a plurality of positioning grooves 49 that are plugged with the positioning block 47. Under normal circumstances, the connecting spring 46 abuts against the positioning block 47, so that it is stably plugged into the positioning groove 49 to maintain the stable position of the cross plate 44. When the direction of the cross plate 44 needs to be adjusted, the electromagnet 48 is energized to attract the positioning block 47 to disengage it from the current positioning groove 49, and then the connecting shaft 43 is manually rotated to the desired angle, and finally the electromagnet 48 is de-energized, and the connecting spring 46 pushes the positioning block 47 to insert it into the new positioning groove 49, so as to achieve precise adjustment of the direction of the cross plate 44.

[0045] There are four positioning grooves 49 and they are arranged along the outer circumference of the fixing sleeve 42. This design allows the angle of the cross plate 44 to be adjusted accurately to ninety degrees each time, which facilitates the accurate installation of the main beam and the rib plate and improves the efficiency and accuracy of the welding work.

[0046] The design of the elastic support member 5 is also ingenious. It includes a slider 51 slidably set in the vertical slide rail 45, a mounting plate 52 is set between the two sliders 51, elastic telescopic rods 53 are set on both sides of the mounting plate 52, and the flexible track 6 is fixedly installed on the end of the elastic telescopic rod 53. An adjusting screw 54 is rotatably set in any one of the vertical slide rails 45. The adjusting screw 54 threadably passes through the slider 51 and a handle is set at the end. The height of the slider 51 can be easily adjusted by turning the handle, thereby adjusting the position of the elastic telescopic rod 53 and the flexible track 6.

[0047] Both sides of the mounting plate 52 are provided with mounting grooves 55, and mounting blocks 56 are slidably disposed in the mounting grooves 55. Support springs 57 are disposed on the mounting blocks 56, and both ends of the support springs 57 are respectively fixedly connected to the mounting blocks 56 and the side walls of the mounting grooves 55. The top of the elastic telescopic rod 53 is fixedly connected to the mounting blocks 56. This design enables the elastic telescopic rod 53 to be movably disposed on the mounting plate 52. When the flexible track 6 is deformed, the elastic telescopic rod 53 can stably support the flexible track 6 to ensure smooth welding.

[0048] The flexible track 6 is made of rubber material and has good flexibility and wear resistance. Both sides of the flexible track 6 are rotatably connected with rotating blocks 8, and a connecting screw 9 is rotatably provided on the rotating block 8. A threaded hole threadedly connected to the connecting screw 9 is provided at the bottom end of the elastic telescopic rod 53. Through this threaded connection method, the flexible track 6 can be easily installed and disassembled to meet the needs of different welding tasks.

[0049] The flexible track 6 is also designed with a slot 10 and a positioning screw 11. The slot 10 is used to fix the main beam or the rib plate. One end of the positioning screw 11 is threaded through the flexible track 6 and extends into the slot 10. When welding, the main beam or the rib plate is placed in the slot 10 and then fastened by the positioning screw 11. In this way, the flexible track 6 can move the main beam or the rib plate to the correct position, greatly improving the accuracy and efficiency of welding.

[0050] In addition, a sliding frame 12 is fixedly arranged on the flexible track 6, a placement block 13 is slidably arranged inside the sliding frame 12, a reduction motor is fixedly arranged on the placement block 13, a walking wheel 14 is arranged at the output end of the reduction motor, the outer surface of the walking wheel 14 is in contact with the top of the flexible track 6, a connecting plate 15 is arranged at the bottom of the reduction motor, and the welding head 7 is fixedly installed on the connecting plate 15. When the reduction motor drives the walking wheel 14 to rotate, the walking wheel 14 will drive the placement block 13 and the welding head 7 to move along the flexible track 6 for welding.

[0051] In summary, when in use, first place the template body on the workbench 1 and position it through the limit plate 3, then adjust the position of the gantry 2 and the connecting frame 4 to align the welding head 7 with the position where welding is required, then adjust the height and angle of the elastic support 5 to make the flexible track 6 fit tightly to the template surface, place the main beam or rib plate in the slot 10 of the flexible track 6, and tighten it through the positioning screw 11, finally, start the reduction motor to drive the welding head 7 to move along the flexible track 6 for welding.

[0052] The present invention also provides a welding method for a steel formwork welding mechanism for pier casting, and the specific steps are as follows:

[0053] Step 1: Place the template body on the workbench 1 and abut its side wall against the limiting plate 3;

[0054] Step 2: Fix a main beam on the flexible track 6 through the slot 10 and the positioning screw 11 on the flexible track 6, and align the main beam with the template body by moving the slide bar 41 on the gantry 2 and the slider 51 in the vertical slide rail 45;

[0055] Step 3: After alignment, the slider 51 is driven to move downward, and the slider 51 drives the flexible track 6 to fit the surface of the wooden board. When the template body has an arc surface, the flexible track 6 is deformed and fits the surface of the template body. Then, the reduction motor is started to drive the welding head 7 to move along the flexible track 6 for welding.

[0056] Step 4: periodically move the slide bar 41 to make the flexible track 6 fit the template surface section by section, and then the welding head 7 welds along the flexible track 6 in sequence, thereby completing the welding of the main beam;

[0057] Step 5: Rotate the cross plate 44 to make the flexible track 6 perpendicular to the main beam, then replace the flexible track 6 to make it equal to the length of the rib plate, and then weld the rib plates in sequence in the above manner.

[0058] Embodiment 2: In order to meet the requirements of different types of templates, the welding head 7 can be installed on the connecting plate 15 by bolts or adjusting buckles to adjust the welding angle.
