[0024] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0025] This application discloses a novel prefabricated post-cast strip formwork system, such as Figure 1 and Figure 2As shown, it includes a post-cast strip 11 set between two floor slabs 1, a panel 2 installed at the bottom of the post-cast strip 11, and multiple sets of support devices 3 set on the ground to support the panel 2. Adjacent sets of support devices 3 are connected by steel pipes.

[0026] like Figure 1 and Figure 2 As shown, each set of support devices 3 includes two bases 31. A mounting frame 32 is vertically mounted on the top of each base 31. A movable plate 33 is vertically slidably connected to the mounting frame 32. A drive assembly for moving the movable plate 33 is mounted on the mounting frame 32. A movable rod 34 is vertically fixed to the top of the movable plate 33, and a support plate 35 is horizontally fixed to the top of the movable rod 34. A blocking mechanism 4 for limiting the panel 2 is mounted on each support plate 35. The two sets of blocking mechanisms 4 are symmetrically arranged. The panel 2 is placed on the support plate 35, and then the blocking mechanism 4 limits the panel 2. Next, the drive assembly drives the movable plate 33 to move upward. The upward movement of the movable plate 33 drives the movable rod 34 to move upward, which in turn drives the support plate 35 to move upward, and the upward movement of the support plate 35 drives the panel 2 to move upward. This allows the panel 2 to be moved to the bottom of the pouring strip. During the movement of the panel 2, the blocking mechanism 4 can block the panel 2, thereby reducing the possibility of the panel 2 separating from the support device 3.

[0027] like Figure 1 and Figure 2 As shown, the drive assembly includes a vertical rod 36 fixed to the inner wall of the mounting frame 32, a lead screw 37 vertically rotatably connected to the side wall of the mounting frame 32 via a bearing, a horizontal shaft 38 horizontally rotatably connected to the side wall of the mounting frame 32 via a bearing, a first bevel gear 381 fixed to one end of the horizontal shaft 38, and a handwheel 382 installed at the other end of the horizontal shaft 38; a second bevel gear 371 is fixedly connected to the lead screw 37, and the first bevel gear 381 meshes with the second bevel gear 371; a moving plate 33 is threaded to the lead screw 37 and slides vertically to the vertical rod 36, and the vertical rod 36 passes through the moving plate 33. When it is necessary to drive the movable plate 33 to move, the horizontal shaft 38 is first driven to rotate by the handwheel 382. The rotation of the horizontal shaft 38 drives the first bevel gear 381 to rotate. The rotation of the first bevel gear 381 drives the second bevel gear 371 to rotate. The rotation of the second bevel gear 371 drives the lead screw 37 to rotate. The rotation of the lead screw 37 can drive the movable plate 33 to move. In summary, the drive assembly is designed to facilitate the movement of the movable plate 33.

[0028] like Figure 1 and Figure 3As shown, the blocking mechanism 4 includes a mounting groove 41 formed in the support plate 35, a first through hole 411 and a second through hole 412 formed in the top wall of the mounting groove 41, a drive plate 42 vertically slidably connected to the first through hole 411, and a blocking plate 43 vertically slidably connected to the second through hole 412. In the initial state, the top of the drive plate 42 protrudes from the top of the support plate 35, the top of the blocking plate 43 is located in the second through hole 412, the top of the drive plate 42 can abut against the bottom of the panel 2, a horizontal plate 44 is fixedly connected to the side wall of the drive plate 42, and multiple vertical rods are vertically fixedly connected to the top of the horizontal plate 44. Each vertical spring 45 is fixed to the top wall of the mounting groove 41 at one end away from the horizontal plate 44; a first rotating shaft 46 is horizontally rotatably connected to the mounting groove 41 via a bearing, and a rotating plate 47 is fixed to the side wall of the first rotating shaft 46. The horizontal plate 44 can drive the rotating plate 47 to rotate. Multiple connecting springs 48 are vertically fixed to the bottom of the rotating plate 47, and the end of each connecting spring 48 away from the rotating plate 47 is fixed to the bottom of the mounting groove 41; a connecting rod 49 is hinged between the blocking plate 43 and the rotating plate 47; a limiting component 5 for limiting the blocking plate 43 is installed on the top of the support plate 35. When panel 2 is placed on support plate 35, panel 2 drives drive plate 42 to move downward under the action of gravity. Drive plate 42 moves downward, causing horizontal plate 44 to move downward. Horizontal plate 44 moves downward, driving rotating plate 47 to rotate. Then, rotating plate 47 drives blocking plate 43 to move upward under the action of connecting rod 49, thus blocking panel 2. In summary, the blocking mechanism 4 facilitates blocking panel 2. In addition, the multiple connecting springs 48 can, on the one hand, overcome the gravity of drive plate 42 and horizontal plate 44, so that the top of drive plate 42 can remain protruding from the top of support plate 35. On the other hand, they can buffer panel 2, thereby reducing the rigid contact between panel 2 and support plate 35.

[0029] like Figure 3 and Figure 4As shown, the limiting component 5 includes a first guide rod 51 horizontally fixed to the top of the support plate 35, a first sliding sleeve 52 slidably connected to the first guide rod 51 in a horizontal direction, a first return spring 53 horizontally sleeved to the first guide rod 51, and a limiting block 54 fixed to the top of the first sliding sleeve 52; one end of the first return spring 53 is fixed to the first sliding sleeve 52, and the other end is fixed to the top of the support plate 35; the limiting block 54 has a first inclined surface 541 at one end near the blocking plate 43, and the first inclined surface 541 matches the side wall of the blocking plate 43; the side wall of the blocking plate 43 has a limiting groove 55, and the limiting block 54 is inserted into the limiting groove 55. When the blocking plate 43 moves upward, the limiting block 54 moves away from the blocking plate 43 under the action of the first inclined surface 541. Then the limiting block 54 applies force to the first return spring 53. When the blocking plate 43 moves into place, the limiting block 54 is inserted into the limiting groove 55 under the action of the first return spring 53, thereby limiting the blocking plate 43 and improving the stability of the blocking plate 43.

[0030] like Figure 1 , Figure 2 and Figure 5 As shown, a first connecting mechanism 6 is provided between the two mounting brackets 32. The first connecting mechanism 6 includes two first connecting plates 61 that are horizontally fixed to the inner sides of the two mounting brackets 32 respectively, two second guide rods 62 that are horizontally fixed to the two first connecting plates 61 respectively, two second sliding sleeves 63 that are slidably connected to the two second guide rods 62 along the length direction of the first connecting plate 61 respectively, a second connecting plate 64 and a third connecting plate 65 that are horizontally fixed to the top of the two second sliding sleeves 63 respectively, and a plurality of second return springs 66 that are horizontally fixed to the two second sliding sleeves 63 respectively. The end of each second spring away from the second sliding sleeve 63 is fixed to the side wall of the first connecting plate 61. The two mounting brackets 32 are respectively provided with third through holes 67 for sliding of the second connecting plate 64 and the third connecting plate 65. The ends of the second connecting plate 64 and the third connecting plate 65 near the mounting bracket 32 ​​are each provided with a second inclined surface 68, and the two second inclined surfaces 68 are matched with the two moving plates 33. The second connecting plate 64 and the third connecting plate 65 are engaged. When the two movable plates 33 move upward, the two movable plates 33 drive the second connecting plate 64 and the third connecting plate 65 to move towards each other under the action of the second inclined surface 68. This allows the second connecting plate 64 and the third connecting plate 65 to engage, thereby improving the overall stability of the two mounting brackets 32. In summary, the first connecting mechanism 6 is provided to improve the overall stability of the two mounting brackets 32.

[0031] like Figure 5As shown, the second connecting plate 64 and the third connecting plate 65 are respectively provided with a locking block 641 and a locking groove 651 at their opposite ends, with the locking block 641 engaging with the locking groove 651; both the locking block 641 and the locking groove 651 extend horizontally, and the bottom of both the second connecting plate 64 and the third connecting plate 65 are fixed with a pull rod 69 by bolts. The locking block 641 and the locking groove 651 facilitate the engagement of the second connecting plate 64 and the third connecting plate 65; the pull rod 69 facilitates the separation of the second connecting plate 64 and the third connecting plate 65 when the engagement is too tight, preventing the second return spring 66 from separating them.

[0032] like Figure 1 , Figure 3 and Figure 6 As shown, a second connecting mechanism 7 is provided between the two moving rods 34. The second connecting mechanism 7 includes two vertical slots 71 respectively opened on the side walls of the two moving rods 34, two second rotating shafts 72 respectively connected to the inner walls of the two vertical slots 71 by bearings, two spur gears 73 respectively sleeved and fixed to the two second rotating shafts 72, and a fourth connecting plate 74 respectively fixed to the two second rotating shafts 72; the two fourth connecting plates 74 can be rotated into the two vertical slots 71 respectively, and the bottom of the two mounting slots 41 is provided with a fourth connecting plate 74. A through hole 75, a vertical plate 76 is vertically slidably connected inside each fourth through hole 75, the bottom of the vertical plate 76 is vertically slidably connected to the vertical groove 71, the top of the two vertical plates 76 is fixedly connected to the bottom of the two horizontal plates 44 respectively; a rack 77 is vertically fixedly connected to the side of the two vertical plates 76 near the second rotating shaft 72, and the two racks 77 mesh with the two spur gears 73 respectively; a fifth connecting plate 78 is provided at the bottom of the two fourth connecting plates 74, and the two ends of the fifth connecting plate 78 are respectively bolted to the bottom of the two fourth connecting plates 74. When panel 2 is placed on support plate 35, panel 2 drives two drive plates 42 to move downward under the action of gravity. The downward movement of the two drive plates 42 drives two horizontal plates 44 to move downward. The downward movement of the two horizontal plates 44 drives two vertical plates 76 to move downward. The downward movement of the two vertical plates 76 drives two racks 77 to move downward. The downward movement of the two racks 77 drives two spur gears 73 to rotate. The rotation of the two spur gears 73 drives two second rotating shafts 72 to rotate. The rotation of the two second rotating shafts 72 makes the two fourth connecting plates 74 horizontal. When it is necessary to connect the two fourth connecting plates 74, the two fourth connecting plates 74 are connected through the fifth connecting plate 78. After the two fourth connecting plates 74 are connected, the overall stability of the two moving rods 34 can be improved. In summary, the second connecting mechanism 7 is provided to improve the overall stability of the two moving rods 34.

[0033] like Figure 1 and Figure 7As shown, a positioning mechanism 8 is provided between the two bases 31. The positioning mechanism 8 includes a positioning plate 81 bolted to the top of one base 31, and a positioning rod 82 vertically slidably connected to the other end of the positioning plate 81. A positioning groove 83 is provided on the top of the other base 31, and the positioning rod 82 is inserted into the positioning groove 83. When the positioning rod 82 is inserted into the positioning groove 83, the locking block 641 is aligned with the locking groove 651, and the second connecting plate 64 and the third connecting plate 65 are also correspondingly positioned. In summary, the positioning mechanism 8 facilitates the alignment of the locking block 641 with the locking groove 651 and the second connecting plate 64 with the third connecting plate 65.

[0034] like Figure 1 and Figure 8 As shown, each floor slab 1 is equipped with a buffer mechanism 9 at its bottom. The buffer mechanism 9 includes a buffer cylinder 91 prefabricated vertically at the bottom of the floor slab 1, a countersunk bolt 92 threaded to the inner wall of the buffer cylinder 91, a buffer seat 93 vertically slidingly connected to the bolt body of the countersunk bolt 92, and a buffer spring 94 vertically fixed to the top of the buffer seat 93. The buffer spring 94 is sleeved on the bolt body of the countersunk bolt 92, and the end of the buffer spring 94 away from the buffer seat 93 is fixed to the inner wall of the buffer cylinder 91. The buffer spring 94 and the buffer seat 93 are provided to facilitate buffering of the top of the panel 2.
