[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 5As shown, this utility model provides an adjustable large template system for deformable joint construction, including a single-sided aluminum alloy template 1, a limiting template 2 on the left side of the single-sided aluminum alloy template 1, a tapered sleeve 3 in the middle of the single-sided aluminum alloy template 1 and the limiting template 2, a first screw 4 engaged on the left side of the tapered sleeve 3, a first nut 5 engaged on the outer side of the first screw 4, a second screw 6 engaged on the right side of the tapered sleeve 3, a second nut 7 engaged on the outer side of the second screw 6, a first vertical back rib 8 sleeved on the outer side of the second screw 6, the first vertical back rib 8 being located on the right side of the tapered sleeve 3, and a first horizontal back rib 9 fixedly installed between the first vertical back rib 8 and the middle of the limiting template 2.
[0023] When a slight adjustment is needed due to an angular deviation in the wall surface, first, place the single-sided aluminum alloy template 1, then engage the first screw 4 with the tapered sleeve 3. Simultaneously, pass the first screw 4 through the inside of the single-sided aluminum alloy template 1 and engage it with the first nut 5 for fixation. Then, engage the tapered sleeve 3 with the second screw 6 for fixation, so that the tapered sleeve 3 drives the second screw 6 to a horizontal state. While maintaining a horizontal state between the limiting template 2 and the single-sided aluminum alloy template 1, the tapered sleeve 3 engages with the first screw 4 and the second screw 6 respectively to adjust the distance between the single-sided aluminum alloy template 1 and the limiting template 2, thereby following the deviation of the building and maintaining a flat state.
[0024] The limiting template 2 has a second vertical back rib 10 on its right side. The second vertical back rib 10 has a groove 11 inside. A slider 12 is slidably connected inside the groove 11. The top of the slider 12 is fixedly connected to the first vertical back rib 8.
[0025] When templates of different heights need to be made, the slider 12 slides inside the groove 11 to adjust the height between the first vertical back rib 8 and the second vertical back rib 10. The templates are then fixed by the engagement of the limiting bolt 14 and the height adjustment hole 13, so as to facilitate height adjustment and achieve the effect of expansion joints that can adapt to different height values.
[0026] The second vertical back rib 10 has a height adjustment hole 13 inside, and a limit bolt 14 is engaged inside the height adjustment hole 13. The limit bolt 14 engages with the slider 12.
[0027] The limiting bolt 14 engages with the height adjustment hole 13 and the slider 12, so that the slider 12 is fixed inside the slide groove 11, so as to make it easy to maintain stability after the distance between the first vertical back rib 8 and the second vertical back rib 10 is adjusted.
[0028] The second vertical back rib 10 has a positioning hole 15 inside, and a rotating shaft 16 is rotatably connected inside the positioning hole 15. The second horizontal back rib 17 is fixedly installed on the right side of the rotating shaft 16.
[0029] The second vertical back rib 10 and the second horizontal back rib 17 are kept perpendicular to each other, so that the surface to be poured can be kept horizontal during the pouring process. At the same time, the angle between the second vertical back rib 10 and the second horizontal back rib 17 can be adjusted by the rotational connection between the pivot 16 and the positioning hole 15, so as to facilitate the adaptation to expansion joints with different angles.
[0030] A fixing block 18 is fixedly installed on the right side of the second vertical back rib 10. A support shaft 19 is rotatably connected inside the fixing block 18. A connecting rod 20 is engaged on the side of the support shaft 19 away from the fixing block 18. The connecting rod 20 is located above the second horizontal back rib 17.
[0031] The connecting rod 20 engages with the support shaft 19, thereby adjusting the distance between the second horizontal back rib 17 and the fixed block 18. At the same time, after engaging with the support shaft 19, the connecting rod 20 can effectively support the angle between the second horizontal back rib 17 and the second vertical back rib 10, thereby achieving a stable effect between the second horizontal back rib 17 and the second vertical back rib 10.
[0032] There are multiple tapered sleeves 3, all of which are located on the left side of the limiting template 2, and the multiple tapered sleeves 3 are distributed vertically. There are multiple first horizontal back ribs 9, which are located in the middle of the second vertical back rib 10 and the limiting template 2, and the first vertical back rib 8 and the limiting template 2, respectively.
[0033] The main function of the first horizontal back rib 9 is to maintain the stability of the connection between the limiting template 2 and the first vertical back rib 8 and the second vertical back rib 10, and to maintain the consistency of the distance, so that it can maintain a horizontal state.
[0034] There are multiple height adjustment holes 13, which are distributed vertically and located behind the slider 12.
[0035] There are two sliders 12, which engage with the two highest height adjustment holes 13 respectively to keep the sliders 12 stable.
[0036] There are two support shafts 19 and two connecting rods 20. Both support shafts 19 and two connecting rods 20 are located above the second horizontal back rib 17 and to the right of the second vertical back rib 10.
[0037] The main function of the two connecting rods 20 is to maintain stable support by engaging with the support shaft 19, in addition to facilitating angle adjustment.
[0038] Working principle and usage process of this utility model:
[0039] First, a second screw 6 is engaged on the right side of the tapered sleeve 3, and a second nut 7 is engaged on the outside of the second screw 6. A first vertical back rib 8 is sleeved on the outside of the second screw 6, and the first vertical back rib 8 is located on the right side of the tapered sleeve 3. At the same time, a first horizontal back rib 9 is fixedly installed between the first vertical back rib 8 and the middle of the limiting template 2. When the wall surface deviates at an angle and needs to be slightly adjusted, after placing the single-sided aluminum alloy template 1, the first screw 4 is engaged with the tapered sleeve 3, and the first screw 4 is simultaneously moved from... The single-sided aluminum alloy template 1 passes through the interior and is fixed by engaging with the first nut 5. Then, the tapered sleeve 3 is engaged with the second screw 6, so that the tapered sleeve 3 drives the second screw 6 to a horizontal state. While keeping the limiting template 2 and the single-sided aluminum alloy template 1 in a horizontal state, the tapered sleeve 3 engages with the first screw 4 and the second screw 6 respectively to adjust the distance between the single-sided aluminum alloy template 1 and the limiting template 2, so as to follow the deviation of the building and maintain a flat state.
[0040] Secondly, a second vertical back rib 10 is provided on the right side of the limiting template 2. A groove 11 is provided inside the second vertical back rib 10, and a slider 12 is slidably connected inside the groove 11. At the same time, the top of the slider 12 is fixedly connected to the first vertical back rib 8. When it is necessary to make templates of different heights, the slider 12 is slidably connected inside the groove 11, so that the height between the first vertical back rib 8 and the second vertical back rib 10 is adjusted. The limiting bolt 14 is fixed by the engagement of the height adjustment hole 13, so as to facilitate the adjustment of the height and achieve the effect of adapting to the deformation joint with different height values.
[0041] Finally, the connecting rod 20 engages with the support shaft 19, thereby adjusting the distance between the second horizontal back rib 17 and the fixed block 18. At the same time, after engaging with the support shaft 19, the connecting rod 20 can effectively support the angle between the second horizontal back rib 17 and the second vertical back rib 10, thereby achieving a stable effect between the second horizontal back rib 17 and the second vertical back rib 10.
