[0029] In this implementation scheme: After checking, the public (announcement) number: CN217299813U discloses a spliced ​​and assembled standardized structural column formwork device, but this formwork device is connected and fixed by bolts. When disassembly is required, due to the large number of bolts, the disassembly will be more laborious, reducing work efficiency and not easy to disassemble quickly. In order to solve this technical problem, a locking component 2 and a positioning component 3 are added on this basis.

[0030] More specifically:

[0031] like Figures 1 to 5 As shown;

[0032] Combining the above:

[0033] In order to realize the rapid disassembly of the formwork, the structural column formwork device further includes a locking component 2 arranged on the surface of the first formwork body 1;

[0046] In this embodiment: when it is necessary to pour the structural column, the two positioning blocks 32 of the second formwork body 11 are respectively inserted into the positioning grooves 31 opened in the first formwork body 1 in two opposite directions, so that the positioning blocks 32 are inserted into the positioning grooves 31 on the other side of the first formwork body 1, so that the two first formwork bodies 1 and the two second formwork bodies 11 form a square, and the second rubber pad 33 fixed on the surface of the second formwork body 11 will fit with the second rubber pad 33 fixed on the surface of the first formwork body 1, so that it is more sealed to prevent leakage during pouring.

[0047] Going further:

[0048] The working principle and use process of the utility model are as follows: when it is necessary to cast the structural column, the two positioning blocks 32 of the second supporting formwork body 11 are respectively inserted into the positioning grooves 31 opened in the first supporting formwork body 1 in two opposite directions, so that the positioning blocks 32 are inserted into the positioning grooves 31 on the other side of the first supporting formwork body 1, so that the two first supporting formwork bodies 1 and the two second supporting formwork bodies 11 form a square, and the second rubber pads 33 fixed on the surface of the second supporting formwork body 11 will interact with the second rubber pads 33 fixed on the surface of the first supporting formwork body 1 The second limiting block 29 is placed on the surface of the first supporting mold body 1, so that the first rubber pad 210 and the first supporting mold body 1 are in contact with each other to increase the friction force.

The force applying rod 23 is applied, and the cam 27 connected to the force applying rod 23 is moved in the limiting groove 2 through the rotating shaft. 8, due to the shape of the cam 27, the surface of the cam 27 will eventually fit with the limiting rod 25, and the limiting rod 25 will slide inside the first limiting block 21 due to the force, and the tension spring 26 connected to the limiting rod 25 will be stretched until the limiting rod 25 is inserted into the limiting hole 24, thereby clamping and fixing the first supporting mold body 1 and the second supporting mold body 11, and then inserting the pin rod 212 into the pin hole 211 until it penetrates the force rod 23, thereby fixing the limiting rod 25. When the pin rod 212 is taken out from the inside of the pin hole 211, an opposite force is applied to the pin hole 211, and the cam 27 will rotate inside the limit groove 28 until the limit on the limit rod 25 is lost. The tension spring 26 will pull the limit rod 25 out of the inside of the limit hole 24 due to its elastic potential energy, and the first limit block 21 and the second limit block 29 can be removed. A force is applied to the second supporting mold body 11 in a direction away from the first supporting mold body 1, so that the positioning block 32 is pulled out from the inside of the positioning groove 31, and the second supporting mold body 11 is removed.
