Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all 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 efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5, an embodiment provided by the present utility model: a synchronous climbing form for a double-column pier, comprising: a protective plate 1, a fixing plate 5 is fixedly connected to the outer surface of the protective plate 1, a protective box 6 is fixedly connected to the outer surface of the fixing plate 5, a connection hole 7 is opened at the top of the protective box 6, a fixing ring 8 is opened at the top of the protective box 6, a threaded screw rod 9 is movably connected inside the fixing ring 8, a sliding block 11 is movably connected to the outer surface of the threaded screw rod 9, a rotating ring 10 is fixedly connected to the outer surface of the threaded screw rod 9, a pushing block 12 is fixedly connected to the side surface of the sliding block 11, sliding grooves 13 are opened on both sides of the pushing block 12, a fixing block 20 is movably connected inside the protective plate 1, and a side plate 21 is fixedly connected to the inner side of the fixing block 20.

[0025] Specifically, through the setting of the fixing block 20, when multiple groups of protective plates 1 are connected, the fixing blocks 20 can be mutually extruded, thereby realizing the function of limit connection, and avoiding the leakage of concrete from the gaps between multiple groups of protective plates 1 during the pouring process.

[0026] Please refer to Figures 1-5 , a support frame 2 is movably connected to the side surface of the protective plate 1, and a cross plate 3 is movably connected to the side surface of the protective plate 1.

[0027] Specifically, through the setting of the support frame 2, when the protective plate 1 is inserted into the inner side of the guide groove 16, the support frame 2 can effectively play a role in supporting and limiting, thereby ensuring the stability of the device.

[0028] Please refer to Figures 1-5 , a guide groove 16 is opened inside the support frame 2, and the side of the fixing block 20 away from the side plate 21 is slidably connected to the inner side of the guide groove 16.

[0029] Specifically, through the setting of the guide groove 16, it can play a guiding role when the protective plates 1 are assembled and connected, so that the installation of multiple groups of protective plates 1 can be more convenient and fast.

[0030] Please refer to Figures 1-5 , a bottom plate 4 is movably connected to the bottom of the support frame 2, and a rotating assembly 14 is fixedly connected to the bottom of the support frame 2.

[0031] Specifically, through the setting of the rotating assembly 14, the support frame 2 can be rotated and folded around the rotating shaft 15, so that the support frame 2 can be rotated to the same horizontal plane as the bottom plate 4, thereby facilitating carrying and transportation.

[0032] Please refer to Figures 1-5 , a rotating shaft 15 is rotatably connected inside the rotating assembly 14, and a folding groove 17 is opened at the bottom of one side of the bottom plate 4.

[0033] Specifically, through the setting of the folding slots 17, when the bottom plate 4 is folded in multiple groups, it is convenient for operation, making the bottom plate 4 more flexible during folding, thereby effectively improving the flexibility of the device.

[0034] Please refer to Figures 1-5 , a flipping member 19 is fixedly connected to the bottom surface of the rotating assembly 14, and a connecting plate 18 is movably connected to the outer surface of the flipping member 19.

[0035] Specifically, through the setting of the flipping member 19, when the bottom plate 4 is unfolded, the flipping member 19 can effectively connect the bottom plate 4, thereby reducing the gap formed between multiple groups of bottom plates 4.

[0036] Please refer to Figures 1-5 , the threaded lead screw 9 and the sliding block 11 are movably connected inside the protective box 6, and both sides of the sliding block 11 are movably connected to the inner wall of the protective box 6.

[0037] Specifically, through the setting of the threaded lead screw 9, when the rotating ring 10 is rotated, it can effectively push the sliding block 11 to displace in the vertical direction, and when the sliding block 11 displaces, it can effectively drive the pushing block 12 to displace synchronously.

[0038] Please refer to Figures 1-5 , two groups of fixing blocks 20 and side plates 21 are symmetrically arranged on both sides of the pushing block 12, and the side plates 21 are slidably connected to the side of the sliding slot 13.

[0039] Specifically, through the setting of the pushing block 12, when the pushing block 12 forms a downward displacement under the push of the sliding block 11, the pushing block 12 will push the fixing block 20 to both sides through the side plates 21, so that multiple groups of protective plates 1 can be tightly connected.

[0040] Working principle: During use, the bottom plate 4 is flipped with the connecting plate 18 as the axis, so that the bottom plate 4 is laid flat. Then, the support frame 2 is rotated with the rotating shaft 15 as the axis through the rotating assembly 14, so that the support frame 2 rotates from the horizontal direction to the vertical direction. Subsequently, the protective plate 1 is slid into the inner side of the support frame 2 along the guiding groove 16. When the protective plate 1 is inserted into the corresponding position, the rotating ring 10 is rotated. Under the rotation of the rotating ring 10, the rotating ring 10 will generate a downward displacement, so that the sliding block 11 will drive the pushing block 12 to displace synchronously. When the pushing block 12 makes a downward horizontal displacement, the sliding slot 13 will push the fixing block 20 to both sides of the protective plate 1 through the side plates 21, thereby realizing the tight connection between multiple groups of protective plates 1 and effectively preventing concrete from leaking out from the gaps between the protective plates 1 during pouring.
