[0030] Example 2:
[0031] See also Figure 1-5 , this embodiment provides a technical solution based on the first embodiment: the bottom support mechanism 5 includes two support beams 51, and a coarse adjustment mechanism 52 is installed on one side of the two support beams 51. The coarse adjustment mechanism 52 includes a sliding frame 521, and both ends of the sliding frame 521 are fixedly connected with a buckle block 522. One side of the buckle block 522 is fixedly connected with a buckle plate 523 by a fastening bolt. One end of the buckle plate 523 is threadedly connected to a limiting bolt 524. One end of the sliding frame 521 is fixedly connected to a slide 525, and one end of the slide 525 is slidably connected to the inner wall of the support beam 51. The inner wall of the slide 525 is threadedly connected with a threaded rod three 526, one end of the threaded rod three 526 is rotatably connected to the inner wall of the support beam 51, and the other end of the threaded rod three 526 passes through the support beam 51 and is rotatably connected to the inner wall of the support beam 51. The threaded rod three 526 rotates to drive the sliding frame 521 to translate. The cam 532 is screwed onto the cam 533 and the cam 534 is screwed onto the cam 533.
[0032] The threaded rod four 531 rotates to drive the adjustment block 532 to translate. A mounting head 63 is fixedly installed on one end of each sliding frame 521 away from the fine-tuning mechanism 53. One side of the two mounting heads 63 is respectively connected to one side of one of the support rods 62 on the two rotating rods 61 through a latch shaft 64 for rotation. The other support rod 62 on the two rotating rods 61 is respectively connected to one side of the two longitudinal beams 41 for rotation. A rotating sleeve 65 is provided in the middle of the rotating rod 61. By rotating the threaded rod three 526, the threaded rod three 526 rotates to drive the slide 525 to move horizontally, thereby driving the sliding frame 521 to move to drive the template thereon to move horizontally to the appropriate position for rough adjustment, and then tighten the limit bolt 524 to fix the sliding frame 521 at the current position. After that, the threaded rod four 531 is rotated by a wrench. The rotation of threaded rod 4 531 drives the adjustment block 532 to move and drives the support shaft 533 and the support angle block 534 to move, thereby driving the template thereon to move horizontally for fine adjustment. Finally, by rotating the rotating sleeve 65, the rotating rod 61 is driven to rotate. The rotation of the rotating rod 61 drives the connecting rod composed of the support rod 62 and the rotating rod 61 to extend or shorten, so that the longitudinal beam 41 rotates along the connection between it and the support shaft 533 as the center of the circle, and then the angle of the template is adjusted by the angle adjustment mechanism 6, so that the template is adjusted to the appropriate position for subsequent operations. At the same time, by rotating the rotating sleeve 65, the rotating rod 61 is driven to rotate, and then the template is pulled to one side first and then the coarse adjustment mechanism 52 is used to move the template horizontally to one side, so as to realize the rapid separation of the template and the frame wall, and facilitate the removal of the template after the frame is formed.
[0033] Working principle: When in use, first fix each keel frame in the keel frame assembly 1 to one side of the building frame template with screws, then clamp the claws 22 with the same number as the keel frames on the two transverse beams 21 to be installed, and place the two transverse beams 21 in parallel on one side of the keel frame assembly 1, and fix each claw 22 to each keel frame with bolts. Then, place two longitudinal beams 41 on the two transverse beams 21 in parallel and at a certain distance, and pass each threaded rod 422 through the middle of the longitudinal beam 41, then put on the gasket 423 and screw on the nut 424, but do not tighten the nut 424;
[0034] Next, fix the two fixing blocks 32 to one side of the two longitudinal beams 41 with bolts, and screw the threaded rod 31 into the fixing block 32 until one end of the threaded rod 31 abuts against the bottom of the transverse beam 21. Then, place the two support beams 51 of the bottom support mechanism 5 on a plane in parallel and at equal distances from the two longitudinal beams 41, and fix them to the plane with bolts. Insert the plug slots 43 on one side of the two longitudinal beams 41 onto the support shaft 533 and the support angle blocks 534 on both sides of the support shaft 533. Finally, install the support rods 62 at one end of the two rotating rods 61 on the two mounting heads 63 through the latch shaft 64, thereby completing the preliminary assembly.
[0035] Then adjust the template. When adjusting, first use the wrench to rotate the threaded rod 31. The rotation of the threaded rod 31 drives the horizontal beam 21 to move up or down, thereby adjusting the keel frame assembly 1 on one side of the horizontal beam 21 to move up and down through the up and down adjustment mechanism 3 to adjust the height of the template. After adjusting the height to the appropriate position, tighten the nut 424 to fix the height. Then use the wrench to rotate the threaded rod 3 526. The rotation of the threaded rod 3 526 drives the slide 525 to move horizontally, thereby driving the sliding frame 521 to move to drive the template on it to move horizontally to the appropriate position for rough adjustment, and then tighten the limit bolt 5 24 fixes the sliding frame 521 in the current position, and then rotates the threaded rod four 531 by using a wrench. The rotation of the threaded rod four 531 drives the adjustment block 532 to move and drives the support shaft 533 and the support angle block 534 to move, thereby driving the template thereon to move horizontally for fine adjustment. Finally, by rotating the rotating sleeve 65, the rotating rod 61 is driven to rotate. The rotation of the rotating rod 61 drives the connecting rod composed of the support rod 62 and the rotating rod 61 to extend or shorten, so that the longitudinal beam 41 rotates along the connection between it and the support shaft 533 as the center of the circle, and then the angle of the template is adjusted by the angle adjustment mechanism 6 to adjust the template to a suitable position.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
