[0029] Example 1

[0030] The embodiment of the present invention provides a drainage ditch construction concrete pouring template, such as Figures 1-6 As shown, it includes: two outer templates 1, side templates 2 are respectively arranged on the front and rear sides of the outer template 1, an inner template 3 is arranged on the side of the side template 2 away from the outer template 1, the two inner templates 3 are located between the two outer templates 1, and a horizontal template 4 is arranged between the two inner templates 3, and the two ends of the horizontal template 4 are detachably connected to the lower end of the inner template 3 through a first connecting mechanism.

[0031] The working principle and beneficial effects of the above technical solution are as follows: both the outer formwork 1 and the inner formwork 3 adopt vertical plates, the side formwork 2 is perpendicular to the outer formwork 1, and the two ends of the side formwork 2 are detachably connected to the outer formwork 1 and the inner formwork 3 by bolts. During construction, the two outer formworks 1, the two inner formworks 3, the horizontal formwork 4 and the two side formworks 2 are transported to the construction position, and then the outer formwork 1 is connected to the side formwork 2, and the inner formwork 3 is connected to the side formwork 2, and then the horizontal formwork 4 is installed between the two inner formworks 3 to form a concrete pouring cavity. After that, only one side formwork 2 can be installed during construction to ensure the connectivity of the drainage ditch construction. The horizontal formwork 4 is detachably connected to the inner formwork 3. Therefore, when constructing drainage ditches of different widths, it is only necessary to adjust the distance between the two inner formworks 3 first, and then replace the horizontal formwork 4 corresponding to the distance between the inner formworks 3, which reduces the use of materials and does not require the inner formwork 3 to be removed from the side formwork 2, reducing the manual adjustment cost and greatly reducing the drainage ditch construction cost.

[0032] Example 2

[0033] On the basis of the above embodiment 1, Figure 1-Figure 4As shown, the first connecting mechanism includes a mounting groove 5, which is provided on the side of the inner template 3 close to the horizontal template 4. A sliding plate 6 is slidably provided in the mounting groove 5. The upper surface of the sliding plate 6 is connected to the top wall of the mounting groove 5 by a first spring 7. One end of the sliding plate 6 extends to the outside of the mounting groove 5 and is provided with a support plate 8. A support groove corresponding to the support plate 8 is provided on the lower surface of the horizontal template 4.

[0034] A sliding hole 9 is provided above the mounting groove 5. The sliding hole 9 is connected to the receiving hole 10 at one end close to the horizontal template 4. The sliding hole 9 and the receiving hole 10 are provided inside the inner template 3. A movable column 11 is provided to slide inside the sliding hole 9. One end of the movable column 11 is connected to the inner wall of the sliding hole 9 via a second spring 12. The other end of the movable column 11 extends into the receiving hole 10 and is provided with a baffle 13.

[0035] A guide hole 14 is provided in the inner template 3. The lower end of the guide hole 14 is connected to the end of the sliding hole 9 away from the receiving hole 10.

[0036] A pull plate 16 is provided at one end of the connecting rope 15 away from the movable column 11;

[0037] The sliding hole 9 is connected to the mounting groove 5 through the guide hole 17. A positioning rod 18 is slidably set in the guide hole 17. The lower end of the positioning rod 18 is connected to the sliding plate 6. A positioning groove 19 adapted to the positioning rod 18 is set on the bottom wall of the movable column 11.

[0038] When the horizontal template 4 is in place, the support plate 8 stops sliding downwards, and the support plate 8 stops sliding downwards, so that the horizontal template 4 can be installed between the two inner templates 3. When the horizontal formwork 4 passes through the baffle 13, the horizontal formwork 4 can be pulled out from between the two inner formworks 3, thereby improving the disassembly efficiency of the horizontal formwork 4.

[0039] Example 3

[0040] On the basis of Example 1 or 2, as Figure 1 As shown, a connecting block 20 is provided on the side of the outer template 1 away from the inner template 3, and the connecting block 20 is connected to the connecting shell 21 through a second connecting mechanism.

[0041] The legs 23 are telescopic rods;

[0042] The upper ends of the two legs 23 are connected by a crossbeam 24;

[0043] The lower end of the support leg 23 is provided with a walking wheel 25 .

[0044] The working principle and beneficial effects of the above technical solution are as follows: the connecting shell 21 can be connected to the connecting block 20 through the hydraulic cylinder 22, thereby tightening the outer formwork 1, improving the reliability of the outer formwork 1, and ensuring the construction quality of the drainage ditch. The support legs 23 made of telescopic rods can adjust the height of the beam 24 so that the height of the beam 24 is always higher than the side formwork 2. The support legs 23 can be driven to move by arranging the walking wheels 25. The support legs 23 on both sides move synchronously under the connection of the beam 24, which is convenient for adjusting the position of the outer formwork 1, shortening the formwork turnover time, and improving the convenience of drainage ditch construction.

[0045] Example 4

[0046] On the basis of Example 3, Figure 1 、 Figure 5 、 Figure 6 As shown, the second connecting mechanism includes a connecting hole 26 provided in the connecting shell 21, the connecting hole 26 is connected to the outside of the connecting shell 21 near the side of the connecting block 20, a movable plate 27 is slidably provided in the connecting hole 26, and a chamfer is provided on the outer periphery of the end of the movable plate 27 away from the connecting block 20, and the side of the movable plate 27 away from the connecting block 20 is connected to the inner wall of the connecting hole 26 through a third spring 28, and a mounting cavity 29 is provided in communication with the bottom of the connecting hole 26, and a slider 30 is slidably provided on the bottom wall of the mounting cavity 29, and a fourth spring 31 is provided on the end of the slider 30 near the connecting block 20, and the end of the fourth spring 31 away from the slider 30 is connected to the push block 32, and the end of the push block 32 away from the fourth spring 31 passes through the connecting hole The side wall of the connecting shell 21 is connected and extends to the outside of the connecting shell 21. The push block 32 is connected to the side wall of the connecting shell 21 by sliding left and right. A pressure plate 33 is provided on the inner wall of the installation cavity 29 close to the connecting block 20. The side wall of the pressure plate 33 is connected to the side wall of the installation cavity 29 by sliding up and down. A pressure block 34 is provided at the end of the pressure plate 33 away from the connecting block 20. An inclined surface is provided on the upper end of the pressure block 34 away from the connecting block 20. A card hole 35 adapted to the upper end of the pressure block 34 is provided on the bottom wall of the connecting block 20. A first connecting rod 36 is provided between the pressure plate 33 and the push block 32. The first connecting rod 36 is hinged to the pressure plate 33 at one end close to the connecting block 20, and is hinged to the push block 32 at one end away from the connecting block 20.

[0047] The working principle and beneficial effects of the above technical solution are as follows: when the outer template 1 is installed, the connecting block 20 is aligned with the connecting hole 26 inside the connecting shell 21, and then the connecting block 20 is inserted into the connecting hole 26. The connecting block 20 contacts the movable plate 27 and drives the movable plate 27 to slide in the connecting hole 26. The third spring 28 is compressed. When the movable plate 27 contacts the upper end of the pressure block 34, the movable plate 27 drives the pressure block 34 to move downward step by step through the chamfered position. The pressure block 34 drives the pressure plate 33 to slide downward along the inner wall of the installation cavity 29. The pressure plate 33 drives the push block 32 to slide into the inside of the installation cavity 29 through the first connecting rod 36. At this time, the pressure plate 33 does not contact the outer wall of the connecting block 20, which reduces the installation resistance of the connecting block 20. At the same time, it can reduce the wear of the connecting block 20 and extend the service life of the connecting block 20. As the connecting block 20 continues to be inserted, when the pressure block 34 contacts the upper end of the pressure block 34, the The locking hole 35 at the bottom of the quasi-connecting block 20, under the elastic force of the fourth spring 31, the push block 32 slides toward the outside of the installation cavity 29, and drives the pressure plate 33 to slide upward through the first connecting rod 36, and the pressure plate 33 drives the pressure block 34 to be inserted into the locking hole 35. At this time, the connecting block 20 is installed in the connecting hole 26 of the connecting shell 21, realizing the quick connection between the outer template 1 and the hydraulic cylinder 22; when the outer template 1 is removed, the push block 32 is pressed into the installation cavity 29, and the push block 32 slides into the installation cavity 29 and drives the pressure plate 33 to slide downward through the first connecting rod 36, and the pressure plate 33 drives the pressure block 34 to slide downward and separate from the locking hole 35. Under the action of the third spring 28, the movable plate 27 pushes the connecting block 20 to slide toward the outside of the connecting hole 26, so that the connecting block 20 can be quickly separated from the connecting hole 26, realizing the rapid disassembly of the outer template 1 and improving the disassembly efficiency.

[0048] Example 5

[0049] On the basis of Example 4, Figure 5 、 Figure 6 As shown, a push plate 37 is provided on the inner wall of the installation cavity 29 away from the connecting block 20, and the push plate 37 is connected to the inner wall of the installation cavity 29 away from the connecting block 20 for sliding up and down. A second connecting rod 38 is provided between the push plate 37 and the slider 30, and the second connecting rod 38 is hingedly connected to the slider 30 at one end close to the connecting block 20, and is hingedly connected to the push plate 37 at one end away from the connecting block 20.

[0050] When the locking cam 35 is in the unlocking state, the locking cam 35 is in the unlocking state, and the locking cam 35 is in the unlocking state, so that the locking cam 35 is locked. When the outer template 1 is opened, as the pushing block 32 is pushed inward, the fourth spring 31 is compressed, and the pushing block 32 first drives the pressure plate 33 to slide downward through the first connecting rod 36, so that the pressure plate 33 is separated from the outer wall of the connecting block 20, and the pressure block 34 is separated from the locking hole 35. Then, the elastic force of the fourth spring 31 drives the slider 30 to slide away from the pushing block 32, and the slider 30 drives the pushing plate 37 to slide upward along the inner wall of the installation cavity 29 through the second connecting rod 38. The upper end of the pushing plate 37 contacts the chamfered position of the movable plate 27 and pushes the movable plate 27 to slide outward, pushing the connecting block 20 to slide outward through the movable plate 27, which helps to quickly separate the connecting block 20 from the connecting hole 26; after the connecting block 20 is separated from the connecting hole 26, the movable plate 27 blocks the entrance of the connecting hole 26, reducing external dust and the like from entering the connecting hole 26, ensuring the cleanliness of the connecting hole 26, reducing the jamming of the connecting block 20 during the insertion of the connecting hole 26, and improving the reliability and stability of the connection between the connecting block 20 and the connecting shell 21.
