[0014] S1. When in use, first place the first template in the designated position, then align the T-shaped hole of the connecting block on the second template with the T-shaped block and then move it downward;

[0015] S2. The second template moves downward, causing the slider, extrusion block, and semicircular concave block to move downward. When the extrusion block contacts the fixed plate, the semicircular concave block partially contacts the semicircular convex block. Then, the U-shaped block continues to move downward, causing the slider to move upward through the extrusion block. The upward movement of the slider causes the rectangular block to move upward. When the rectangular block moves out of the rectangular groove, the second movable column is released.

At this time, since the other end of the support plate rotates and is connected to the movable column, the support plate will rotate. When the support plate contacts the ground, the first template, the connecting plate and the support plate present a triangular support structure, which then provides support, thereby supporting the first template and multiple second templates at the same time;

[0018] S5. When dismantling is required, first pull the ring to move the trapezoidal block and release the fixation. At this time, move the second template upward. The upward movement of the second template will make the extrusion block no longer contact with the fixed plate. At this time, the slider is reset under the action of the tension spring, thereby fixing the second movable column to prevent the second movable column from rotating itself.

The sides of the first fixed block 5 and the second fixed block 6 are both provided with fixing plates 11. The second fixed block 6 is provided with a U-shaped block 12 at the end close to the first fixed block 5. The U-shaped block 12 is provided with a fixing component for fixing the second movable column 8. The advantage of such an arrangement is that, through the arrangement of the semicircular protrusion 9 and the semicircular block 10, it is convenient to connect the first movable column 7 and the second movable column 8, so that they can rotate simultaneously.

[0035] like Figure 7 As shown, the fixing assembly includes sliding grooves respectively opened on the inner walls on both sides of the U-shaped block 12, and sliding rods 13 are installed on the opposite inner walls of the two sliding grooves. A slider 14 is slidably sleeved on the two sliding rods 13, and a rectangular block 16 is installed at the bottom of the slider 14. A rectangular groove adapted to the rectangular block 16 is opened on the outer wall of the peripheral side of the second movable column 8, and two extrusion blocks 17 are installed at the bottom of the slider 14. An elastic unit is provided at the bottom of the slider 14. The advantage of this arrangement is that the second movable column 8 is easily fixed by the arrangement of the sliding rod 13, the slider 14 and the rectangular block 16, so as to avoid the second movable column 8 rotating by itself when not in use and affecting the next connection.

[0036] like Figure 7As shown, the elastic unit includes two tension springs 15 installed at the bottom of the slider 14, and the other ends of the two tension springs 15 are respectively installed on the bottom inner walls of the two slide grooves. The advantage of this arrangement is that through the arrangement of the tension springs 15, when the slider 14 is not under force, the slider 14 is reset.

[0037] like Figure 5 As shown, the driven mechanism includes a circular block 18 which is respectively installed on the side of the first template 1 and the second template 2, and the relative inner walls of the two circular blocks 18 are rotatably installed with a screw rod 19. The two screw rods 19 are respectively installed with the first movable column 7 and the second movable column 8 through a transmission assembly. The two screw rods 19 are threaded with a threaded block 21, and the relative inner walls of the two circular blocks 18 are rotatably installed with a guide rod 22. The tops of the two threaded blocks 21 are provided with guide holes, and the two guide rods 22 respectively pass through the two guide holes. The two threaded blocks 21 are respectively installed with the two support plates 27 through a connecting rod assembly. The advantage of this arrangement is that the threaded block 21 can be easily moved up and down by setting the circular block 18, the screw rod 19, the threaded block 21 and the guide rod 22.

[0038] like Figure 5 As shown, the transmission assembly includes a second bevel gear 40 respectively sleeved on the first movable column 7 and the second movable column 8, the top ends of the two screw rods 19 respectively extend into the two movable cavities and are installed with first bevel gears 20, and the two first bevel gears 20 are respectively engaged with the two second bevel gears 40. The advantage of this arrangement is that through the arrangement of the first bevel gear 20 and the second bevel gear 40, the first movable column 7 and the second movable column 8 rotate and the screw rod 19 rotates at the same time.

[0039] like Figure 5 and Figure 8 As shown, the connecting rod assembly includes fixed columns 23 respectively installed on both sides of the threaded block 21, and a connecting plate 24 is rotatably sleeved on the two fixed columns 23. Two grooves are provided on the top of the support plate 27, and the opposite inner walls of the two grooves are installed with through columns 28. One end of the two connecting plates 24 is rotatably sleeved on the two through columns 28. The advantage of this arrangement is that through the arrangement of the fixed columns 23, the connecting plates 24 and the through columns 28, it is convenient to rotate the support plate 27 to a certain angle.

[0040] like Figure 6As shown, the sides of the first template 1 and the second template 2 are both installed with limiting blocks 29, the side of the second template 2 is installed with a moving block 34, the side of the moving block 34 is installed with an L-shaped plate 35, the side of the L-shaped plate 35 is provided with a limiting groove, the top of the two limiting blocks 29 are provided with a socket adapted to the L-shaped plate 35, the two limiting blocks 29 are provided with a moving cavity, the relative inner walls of the two moving cavities are both installed with two movable rods 30, and each two adapted movable rods 30 are slidably sleeved with a movable block 31, the sides of the two movable blocks 31 are respectively installed with a trapezoidal block 33 adapted to the limiting groove, the side inner walls of the two moving cavities are respectively provided with avoidance holes connected to the two sockets, the two trapezoidal blocks 33 respectively penetrate the two avoidance holes, and the sides of the two movable blocks 31 are both installed with two extrusion holes. The compression spring 32 and the other ends of the two extrusion springs 32 on the same side are installed on the side inner wall of the movable cavity. The sides of the two movable blocks 31 are installed with steel wire ropes 36. The sides of the two limit blocks 29 are opened with rope holes. The other ends of the two steel wire ropes 36 pass through the two rope holes respectively and are installed with pull rings 37. The tops of the two limit blocks 29 are installed with limit rods 38 that are compatible with the pull rings 37. The advantage of this arrangement is that, through the arrangement of the limit blocks 29, movable rods 30, movable blocks 31, extrusion springs 32, trapezoidal blocks 33, fixed blocks 34 and L-shaped plates 35, it is convenient to fix the second template 2 to avoid up and down movement during use. Through the arrangement of steel wire ropes 36, pull rings 37 and limit rods 38, it is convenient to move the trapezoidal block 33 to release the fixation of the second template 2.

[0041] like Figure 1 As shown, T-shaped blocks 3 are installed on the sides of the first template 1 and the second template 2, and a connecting block 4 is installed on the other side of the second template 2. A T-shaped hole that is compatible with the T-shaped block 3 is opened on the top of the connecting block 4. One end of the first movable column 7 extends to the outside of the first fixed block 5 and is installed with a flange 39. The advantage of this arrangement is that, through the arrangement of the T-shaped block 3 and the connecting block 4, a certain guiding role is played to avoid misalignment during connection, and through the arrangement of the flange 39, it is convenient to connect with an external drive component.

[0042] A construction method for casting a shaped formwork, the method comprising:

[0043] S1. When in use, first place the first template 1 at the designated position, then align the T-shaped hole of the connecting block 4 on the second template 2 with the T-shaped block 3 and then move it downward;

[0044] S2, the second template 2 moves downward, causing the slider 14, the extrusion block 17 and the semicircular concave block 10 to move downward. When the extrusion block 17 contacts the fixed plate 11, the semicircular concave block 10 partially contacts the semicircular protrusion 9. Then the U-shaped block 12 continues to move downward, causing the slider 14 to move upward through the extrusion block 17. The upward movement of the slider 14 causes the rectangular block 16 to move upward. When the rectangular block 16 moves out of the rectangular groove, the fixation of the second movable column 8 is released. At the same time, the semicircular concave block 10 is fully in contact with the semicircular protrusion 9, so that the first movable column 7 is connected to the second movable column 8.

[0045] S3, at the same time, the second template 2 moves downward, which causes the L-shaped plate 35 to move downward through the moving block 34. The L-shaped plate 35 moves downward and is fixed by the trapezoidal block 33 and the extrusion spring 32, thereby fixing the second template 2;

[0046] S4. Then, according to the above operation, the other multiple second templates 2 are connected to the first second template 2 in sequence. When support is needed, the flange 39 is used to connect the external driving member, and then the first movable column 7 rotates. The rotation of the first movable column 7 will cause the semicircular protrusion 9 and the semicircular recess 10 to cause the second movable column 8 to rotate. The rotation of the first movable column 7 and the second movable column 8 will cause the screw rod 19 to rotate through the first bevel gear 20 and the second bevel gear 40. The rotation of the screw rod 19 will cause the threaded block 21 to move downward. The downward movement of the threaded block 21 will cause the fixed column 23, the connecting plate 24 and the through column 28 to give the support plate 27 an oblique downward force. At this time, since the other end of the support plate 27 rotates and is connected to the movable column 26, the support plate 27 will rotate. When the support plate 27 contacts the ground, the first template 1, the connecting plate 24 and the support plate 27 present a triangular support structure, and then provide support, thereby supporting the first template 1 and multiple second templates 2 at the same time;

[0047] S5. When dismantling is required, first pull the ring 37 to move the trapezoidal block 33 to release the fixation. At this time, move the second template 2 upward. The upward movement of the second template 2 will make the extrusion block 17 no longer in contact with the fixed plate 11. At this time, the slider 14 is reset under the action of the tension spring 15, thereby fixing the second movable column 8, thereby preventing the second movable column 8 from rotating itself.

[0048] Working principle of the present invention:

[0049] When in use, first place the first template 1 in the designated position, then align the T-shaped hole of the connecting block 4 on the second template 2 with the T-shaped block 3 and then move it downward. The downward movement of the second template 2 will cause the second fixed block 6 to move downward, and the downward movement of the second fixed block 6 will cause the second movable column 8 and the U-shaped block 12 to move downward. The downward movement of the second movable column 8 will cause the semicircular concave block 10 to move downward, and the downward movement of the U-shaped block 12 will cause the slider 14 and the extrusion block 17 to move downward. When the extrusion block 17 contacts the fixed plate 11, the semicircular concave block 10 partially contacts the semicircular protrusion 9. Then, the U-shaped block 12 continues to move downward, which will cause the slider 14 to move upward through the extrusion block 17. The upward movement of the slider 14 will cause the rectangular block 16 to move upward. When the rectangular block 16 moves out of the rectangular groove, the second movable When the second template 2 is in use, the second template 2 is fixed, and the semicircular concave block 10 is in full contact with the semicircular convex block 9, thereby connecting the first movable column 7 with the second movable column 8. When the second template 2 moves down, the movable block 34 moves down, and the movable block 34 moves down, so that the L-shaped plate 35 moves down. The L-shaped plate 35 moves down and squeezes the trapezoidal block 33 to make it avoid. When the limit groove on the L-shaped plate 35 is aligned with the trapezoidal block 33, the trapezoidal block 33 is reset under the action of the extrusion spring 32 and the movable block 31. The reset of the trapezoidal block 33 will fix the L-shaped plate 35, and then fix the second template 2 to prevent the second template 2 from sliding up and down during use. Then, according to the above operation, connect the other multiple second templates 2 to the first second template 2 in sequence. When support is needed, The first movable column 7 is connected to the external driving member through the flange 39, and then the first movable column 7 is rotated by the external driving member. The rotation of the first movable column 7 will cause the semicircular protrusion 9 and the semicircular recess 10 to rotate the second movable column 8. The rotation of the first movable column 7 and the second movable column 8 will cause the second bevel gear 40 to rotate. The rotation of the second bevel gear 40 will cause the first bevel gear 20 to rotate. The rotation of the first bevel gear 20 will cause the screw rod 19 to rotate. The rotation of the screw rod 19 will cause the threaded block 21 to move downward under the action of the guide rod 22. The downward movement of the threaded block 21 will cause the fixed column 23 to move downward. The downward movement of the fixed column 23 will give the support plate 27 an oblique downward force through the connecting plate 24 and the through column 28. At this time, since the other end of the support plate 27 rotates and is sleeved on the movable column 26, When the support plate 27 is in contact with the ground, the first template 1, the connecting plate 24 and the support plate 27 present a triangular support structure, thereby supporting the first template 1 and multiple second templates 2 at the same time, without multiple adjustments, which is easy to use. When it needs to be dismantled, the support plate 27 is reset first, and then the pull ring 37 is pulled. The movement of the pull ring 37 will move the movable block 31 through the wire rope 36. The movement of the movable block 31 will move the trapezoidal block 33, thereby releasing the fixation. At this time, the second template 2 is moved up. The upward movement of the second template 2 will make the extrusion block 17 not contact the fixed plate 11. At this time, the slider 14 is reset under the action of the tension spring 15, thereby fixing the second movable column 8, thereby avoiding when not in use.The second movable column 8 rotates by itself and affects the next connection.

7. A construction method for casting a fixed formwork for a construction project according to claim 6, characterized in that: The method includes: S1. When in use, first place the first template (1) at the designated position, then align the T-shaped hole of the connecting block (4) on the second template (2) with the T-shaped block (3) and then move it downward; S2, the second template (2) moves downward, which drives the slider (14), the extrusion block (17) and the semicircular concave block (10) to move downward. When the extrusion block (17) contacts the fixed plate (11), the semicircular concave block (10) partially contacts the semicircular convex block (9). Then, the U-shaped block (12) continues to move downward, which causes the slider (14) to move upward through the extrusion block (17). The upward movement of the slider (14) causes the rectangular block (16) to move upward. When the rectangular block (16) moves out of the rectangular groove, the second movable column (8) is released from the fixation. At the same time, the semicircular concave block (10) is fully in contact with the semicircular convex block (9), so that the first movable column (7) is connected to the second movable column (8). S3, when the second template (2) moves downward, the L-shaped plate (35) moves downward through the moving block (34), and the L-shaped plate (35) moves downward and is fixed by the trapezoidal block (33) and the extrusion spring (32), thereby fixing the second template (2); S4. Then, according to the above operation, multiple second templates (2) are connected to the first second template (2) in sequence. When support is required, the flange (39) is connected to the external driving member, and then the first movable column (7) is rotated. The rotation of the first movable column (7) causes the semicircular protrusion (9) and the semicircular recess (10) to rotate the second movable column (8). The rotation of the first movable column (7) and the rotation of the second movable column (8) causes the screw rod (19) to rotate through the first bevel gear (20) and the second bevel gear (40). The rotation of the screw rod (19) will The threaded block (21) moves downward, and the downward movement of the threaded block (21) causes the fixed column (23), the connecting plate (24) and the through column (28) to give the support plate (27) an oblique downward force. At this time, since the other end of the support plate (27) is rotated and connected to the movable column (26), the support plate (27) is rotated. When the support plate (27) contacts the ground, the first template (1), the connecting plate (24) and the support plate (27) present a triangular support structure, thereby supporting the first template (1) and the plurality of second templates (2) at the same time; S5. When dismantling is required, first pull the ring (37) to move the trapezoidal block (33) and release the fixation. At this time, move the second template (2) upward. The upward movement of the second template (2) will cause the extrusion block (17) to not contact the fixed plate (11). At this time, the slider (14) is reset under the action of the tension spring (15), thereby fixing the second movable column (8) and preventing the second movable column (8) from rotating itself.
