[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] Example: Figures 1 to 5 As shown, a fastening device for prefabricated building square column formwork that is easy to assemble and disassemble includes a fixed shell 1 and a rotating rail 2. There are two fixed shells 1 and two rotating rails 2. Each fixed shell 1 and a rotating rail 2 connected to it form a group. One side of the fixed shell 1 in the same group overlaps and crosses with one side of the rotating rail 2 in the other group to form a whole. A first fixing groove 3 is opened on one side of the fixed shell 1, a second fixing groove 4 is opened on one side of the rotating rail 2, and a rotating groove 5 is opened on one side of the fixed shell 1. A rotating column 6 is fixedly connected inside the rotating groove 5. One side of the rotating rail 2 is movably connected to the inside of the rotating column 6. A limiting groove 7 is opened inside the rotating groove 5.

[0031] The size of the first fixing groove 3 is the same as that of the second fixing groove 4. A bolt 8 is inserted into the inside of the first fixing groove 3 and the second fixing groove 4. The bolt 8 and the corresponding nut are matched to fix the overlapping fixing shell 1 and the rotating rail 2, thereby fixing the overall shape of the fastening device.

[0032] The shape and size of the bolt 8 are adapted to the shape and size of the first fixing groove 3 and the second fixing groove 4. The outer surface of the bolt 8 is movably connected to the inside of the first fixing groove 3 and the second fixing groove 4. By moving the position of the bolt 8 between the first fixing groove 3 and the second fixing groove 4, the interval between the two sets of corresponding fixing shells 1 and rotating rails 2 can be adjusted, so that the overall shape of the fastening device can be quickly adjusted.

[0033] The shape and size of the rotating groove 5 are adapted to the shape and size of the rotating rail 2. One side of the rotating rail 2 is movably connected to the inside of the rotating groove 5. Through the cooperation between the rotating groove 5 and the rotating column 6, the rotating rail 2 can rotate inside the rotating groove 5, thereby allowing the angle between the rotating rail 2 and the fixed shell 1 to be adjusted.

[0034] A movable groove 9 is provided on one side of the rotating column 2. The shape and size of the movable groove 9 are adapted to the shape and size of the rotating column 6. The inner surface of the movable groove 9 is movably connected to the outer surface of the rotating column 5.

[0035] The size of the limiting groove 7 is larger than that of the rotating bar 2. Through the cooperation of the movable groove 9 and the rotating column 6, the rotating bar 2 can be horizontally displaced inside the rotating groove 5, so that the rotating bar 2 can be pushed into the limiting groove 7 and limited to a certain extent. This allows the rotating bar 2 and the fixed shell 1 to maintain a relatively perpendicular state, making it easier to fasten the square column template.

[0036] A fastening device for prefabricated building square column formwork that is easy to assemble and disassemble, the working principle of which is as follows:

[0037] When the fastening device needs to be moved, the fixed rail 2 is rotated to be directly below the fixed shell 1 to store the rotating rail 2. When the square column template needs to be fastened, the rotating rail 2 is rotated to be perpendicular to the fixed shell 1 by the cooperation of the rotating column groove 5 and the rotating column 6. Then, the rotating rail 2 is pushed so that one side enters the limiting groove 7 to limit it. After the bolt 8 is inserted into the corresponding first fixing groove 3 and second fixing groove 4, the overall shape of the fastening device is fixed by tightening the nut, thus completing the fastening of the square column template. By moving the position of the bolt 8 in the corresponding first fixing groove 3 and second fixing groove 4, the overall shape of the fastening device is changed, so that the fastening device can be adjusted according to the size of the square column template.

[0038] Compared with the prior art, the present invention has the following advantages:

[0039] 1. By cooperating with the rotating column 6 and the movable groove 9, the rotating bar 2 can be folded and rotated under the fixed shell 1, thereby reducing the overall size of the device and making it more convenient to carry and transport.

[0040] 2. By using the combination of bolt 8 and nut, the fastening device is tightened and limited, making the operation of the fastening device simple and quick, and enabling the fastening of the square column formwork to be achieved quickly.

[0041] 3. By adjusting the position of bolt 8 within the first fixing groove 3 and the second fixing groove 4, the fastening device can be adapted to the size and shape of the square column template. Furthermore, since the bolt 8 is fixed to the nut, the adjustment can be performed quickly and conveniently, effectively improving the construction efficiency of workers.
