The prefabricated pillar form 100 includes, for example, a prefabricated base form 10, two first prefabricated side forms 20, and two second prefabricated side forms 30. The prefabricated bottom formwork 10 is provided with a first pouring side 11, the first pouring side 11 is provided with a pouring position (not shown in the figure), and two symmetrical first installation positions (not shown in the figure) and two symmetrical second installation positions (not shown in the figure) are arranged around the pouring position; each first prefabricated sideform 20 is provided with a second casting side 21 and each second prefabricated sideform 30 is provided with a third casting side 31.

Each first prefabricated side template 20 is correspondingly arranged on each first installation position one by one, and then two second pouring sides 21 are arranged in a mutually facing mode; each second prefabricated side formwork 30 is correspondingly arranged on each second installation position one by one, and two third pouring sides 31 of the second prefabricated side formworks are arranged in a mutually facing mode, so that a prefabricated column space surrounded by the prefabricated bottom formwork 10, the two first prefabricated side formworks 20 and the two second prefabricated side formworks 30 is formed. And a prefabricated stand column opening is formed in one end, far away from the prefabricated bottom formwork 10, of the prefabricated stand column space.

For example, the first installation position is a first limit baffle (not shown in the figure) protruding from the surface of the first casting side 11, and is connected to an end of the first prefabricated side formwork 20 in a matching manner, specifically, the first limit baffle is arranged on a side of the first prefabricated side formwork 20 away from the second casting side 21 to limit the movement of the first prefabricated side formwork on the first casting side 11; in contrast, the second mounting position is a second limiting baffle (not shown in the figure) protruding from the surface of the first casting side 11, and is connected with one end of the second prefabricated side template 30 in a matching manner, specifically, the second limiting baffle is arranged on one side of the second prefabricated side template 30 far away from the third casting side 31 thereof to limit the movement of the second prefabricated side template on the first casting side 11.

Preferably, the first installation position is a limiting block protruding from the surface of the first pouring side 11, and the first prefabricated side template 20 is provided with a notch connected with the limiting block in a matching manner.

The matching relationship between the first installation position and the first prefabricated side template 20 and the matching relationship between the second installation position and the second prefabricated side template 30 are not limited to the above examples, and the specific implementation manner may be that the first installation position may also be a first limit block protruding from the first pouring side 11 and matched and connected with a first notch at one end of the first prefabricated side template 20, and similarly, the second installation position may also be a second limit block protruding from the first pouring side 11 and matched and connected with a second notch at one end of the second prefabricated side template 30. And then the two first prefabricated side templates 20 and the two second prefabricated side templates 30 are respectively limited on the prefabricated bottom template 10.

Referring to fig. 2, specifically, each first prefabricated side form 20 is provided with a first connecting surface 23, and the first connecting surfaces 23 are located at two sides of the second pouring side 21; each second prefabricated sideform 30 is provided with a second connecting surface 33, the second connecting surfaces 33 being located on both sides of the third casting side 32. The first connecting surfaces 23 are connected with the corresponding second connecting surfaces 33 in a matching way. For example, the first connecting surface 23 and the second connecting surface 33 are respectively provided with a plurality of connecting holes, and are connected with the plurality of connecting holes through a plurality of fasteners, so as to connect the first prefabricated side mold plate 20 and the corresponding second prefabricated side mold plate 30.

With continued reference to fig. 2, each of the first prefabricating side formworks 20 is provided with two first limiting parts 22. The two first position-limiting portions 22 are respectively located on one side of the first connecting surface 23 close to the second casting side 21. For example, when the first prefabricated side template 20 is matched and connected with the second prefabricated side template 30, the first limiting part 22 can precisely match and connect the second prefabricated side template 30 to the first prefabricated side template 20 through the limiting function of the second prefabricated side template.

Referring to fig. 4-5, preferably, each first position-limiting portion 22 is located on a side of the first connecting surface 23 away from the second casting side 21. Each of the first position-limiting portions 22 includes, for example, a fourth position-limiting member 223 and a fifth position-limiting member 224. The fourth limiting member 223 is located on a side of the first connecting surface 23 away from the second casting side 21, and the fifth limiting member 224 is located on a side of the first connecting surface 23 away from the prefabricated bottom form 10. For example, in the process that the second prefabricated side template 30 is in fit connection with the first prefabricated side template 20, the fourth limiting member 223 can limit the second prefabricated side template 30 to move in the direction away from the second pouring side 21, that is, to move in the Y-direction; the fifth limiting member 224 can limit the second prefabrication side formwork 30 from moving away from the prefabrication bottom formwork 10, namely, the movement in the direction of X.

Wherein, each first connecting plate 41 is provided with a first connecting hole 411, and the second connecting plate 42 is provided with a second connecting hole 421.

In contrast, the second connecting member 50 has the same structure as the first connecting member 40, and thus, the description thereof is omitted.

For example, the prefabricated column steel reinforcement framework for the prefabricated column is too long, so that the existing prefabricated column formwork 100 cannot be integrally cast, and the existing prefabricated column formwork 100 needs to be lengthened. Thus, two first prefabricated side templates 20 and two second prefabricated side templates 30 can be added on the basis of the existing prefabricated column template 100. One end of each of the two newly added first prefabricated side templates 20, which is provided with the first connecting piece 40, is butted with the two existing first prefabricated side templates 20, and a plurality of fastening pieces respectively penetrate through the corresponding second connecting holes 42 of the two newly added first prefabricated side templates 20, so that the first prefabricated side templates 20 are lengthened; in contrast, the process for lengthening the second prefabricated side mold plate 30 is the same as the above-described operation, and thus, a detailed description thereof will be omitted. Thus, an elongated prefabricated column form 100 is obtained to meet the length requirements for the prefabricated column.
