DETAILED DESCRIPTION

[0021] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figures 1 to 5 The utility model provides a technical solution: a pier template, including an upper template 1 and a lower fixed block 4, a lower template 2 is installed on the top of the upper template 1, an upper fixed block 3 is installed on one side of the upper template 1, and the lower fixed block 4 is installed on one side of the lower template 2.

[0024] The top of the lower fixed block 4 is slidably connected to the connecting block 5 through a slide groove, a movable block 6 is installed in the middle of the connecting block 5 through a through hole, a sealing strip 7 is provided on one side of the movable block 6, a screw rod 8 is penetrated and connected to one side of the upper fixed block 3, and a top block 9 is connected to one side of the screw rod 8 through a bearing, and the screw rod 8 and the upper fixed block 3 are threadedly connected.

[0025] Embodiment 2

[0026] On the basis of the first embodiment, in order to prevent the concrete inside the pier formwork from leaking, the connecting block 5 on the top of the lower fixing block 4 can be inserted into the groove of the upper fixing block 3. When the connecting block 5 is inserted into the groove at the bottom of the upper fixing block 3, the screw 8 can be rotated. Since the screw 8 and the upper fixing block 3 are threadedly connected, and one side of the screw 8 is connected to the top block 9 through a bearing, the rotating screw 8 can drive the top block 9 to move, so that the top block 9 moves into the groove of the connecting block 5 and squeezes the movable block 6 in the groove of the connecting block 5. The movable block 6 moves to one side when squeezed, so that the movable block 6 squeezes the sealing strip 7, and the sealing strip 7 moves toward the direction of the formwork. When the sealing strip 7 is squeezed, it will be deformed, so that the gap between the upper formwork 1 and the lower formwork 2 can be sealed, so as to prevent the concrete inside the upper formwork 1 and the lower formwork 2 from flowing out of the gap, so that the entire pier formwork has a better effect of preventing concrete leakage.

[0027] A lower fixing frame 10 is installed on one side of the lower template 2, and an insertion rod 11 is installed on the top of the lower fixing frame 10. A rotating rod 12 is connected to the top of the insertion rod 11, and a rotating block 13 is installed between the rotating rod 12 and the groove of the insertion rod 11. A slider 14 is connected to the middle of the rotating block 13 through an arc groove, and the bottom of the slider 14 is connected to a telescopic block 15 that passes through the insertion rod 11. A movable spring 16 is installed between the telescopic block 15 and the groove of the insertion rod 11, and an upper fixing frame 17 is sleeved on the outer side of the insertion rod 11. The upper fixing frame 17 is installed on one side of the upper template 1.

[0028] Embodiment 3

[0029] On the basis of the second embodiment, in order to reinforce the upper template 1 and the lower template 2, when installing the upper template 1 and the lower template 2, the plug rod 11 on the top of the lower fixing frame 10 can be plugged into the through hole of the upper fixing frame 17. When plugging the plug rod 11, the rotating rod 12 is rotated so that the rotating rod 12 drives the rotating block 13 to rotate. Since the rotating block 13 is provided with arc grooves all around, and a slider 14 is slidably connected in the middle of the arc groove, the rotation of the rotating block 13 will drive the arc groove to rotate, and at the same time, the slider 14 slides through the arc groove. The bottom of the slider 14 is connected to the telescopic block 15, and the slider 14 will drive the telescopic block 15 to retract while sliding along the arc groove. The telescopic block 15 is retracted into the groove of the insertion rod 11, and the movable spring 16 is in a stretched state through the telescopic block 15. When the telescopic blocks 15 around the insertion rod 11 completely pass through the upper fixing frame 17, the rotating rod 12 is released, so that the rotating block 13 does not generate a pulling force on the telescopic block 15 through the arc groove and the slider 14, and then the telescopic block 15 is reset by the movable spring 16, so that the rotating block 13 rotates in the opposite direction, and the telescopic block 15 is moved out of the groove of the insertion rod 11 at the same time. The insertion rod 11 can be limited to the upper fixing frame 17 through the telescopic block 15, so that the connection between the two sets of templates can be more stable, which plays a role in reinforcing the template, and also facilitates and quickly fixes the template.

[0030] During actual use, the lower formwork 2 is fixed on the foundation, and then the upper formwork 1 and the lower formwork 2 are connected in turn, and fixed by means of the inserted rod 11 and the screw rod 8, so that the upper formwork 1 and the lower formwork 2 form the main shape of the bridge pier, and then steel bars can be added to the inside of the formwork, and concrete can be poured. After the concrete solidifies, the formwork can be removed, thereby completing the construction of the bridge pier.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
