[0029] At least a pair of mounting plates 2, the mounting plates 2 are rectangular plates, and a fastening part 6 is formed by extending on one surface of the mounting plates 2. The fastening part 6 is located at a position close to the end of the mounting plates 2, and the main body of the fastening part 6 is square. The two paired mounting plates 2 are arranged side by side for fixing two adjacent aluminum formworks 1.

[0030] A connecting piece 8, the connecting piece 8 is adapted to the edge side holes of the aluminum alloy formwork, that is, the rod diameter of the connecting piece 8 is adapted to the aperture of the edge side holes, and a fastening hole adapted to the connecting piece 8 is opened on the fastening part 6.

[0031] A support mechanism, the support mechanism is arranged on the back surface of the mounting plate 2, that is, on the surface away from the fastening part 6. One end of the support mechanism is connected to the mounting plate 2, and the other end is a fixed end for fixing.

[0032] As Figure 1 shown, in the construction state, taking the fixation of two aluminum formworks 1 as an example, the two mounting plates 2 are arranged side by side, so that the two aluminum formworks 1 are adjacent and aligned. The connecting piece 8 is passed through the fastening holes of the two connected mounting plates 2 and at the same time through the edge side holes of the two adjacent aluminum formworks 1, connecting the two aluminum formworks 1 and the two mounting plates 2 into a whole, and then fixing the whole device on the ground through the support mechanism, so as to realize the fixation of the aluminum formwork 1 during the construction process.

[0033] Further, in this embodiment, the connecting piece 8 is specifically a tie rod. Please refer to Figure 2 、 Figure 4, the fastening part 6 includes a connecting part 17 and an abutting part 16. The connecting part 17 is square-shaped, connected to the back surface of the mounting plate 2 or integrally formed with the mounting plate 2. The connecting part 17 is located at one end of the mounting plate 2 close to another adjacent mounting plate 2, and the connecting part 17 extends in the up and down direction. The number of the abutting parts 16 is two, and they are respectively located at the upper and lower ends of the connecting part 17. The abutting parts 16 extend obliquely in the direction close to another adjacent mounting plate 2, that is, the abutting parts 16 are structured to extend obliquely outward and upward, and the end forms an abutting surface parallel to the inner edge of the aluminum alloy formwork, that is, the end abutting surface extends in the up and down direction to facilitate close fitting with the inner edge of the aluminum alloy formwork.

[0034] Further, in this embodiment, the fastening device further includes a locking block 7. The number of the locking blocks 7 is adapted to the number of the abutting parts 16. For example, when fixing two aluminum formworks 1, the number of the locking blocks 7 used is four. A locking hole adapted to the connecting piece 8 is formed on the locking block 7. The locking hole is used for the connecting piece 8 to pass through. The locking block 7 is arranged on the side of the abutting part 16 away from another mounting plate 2, that is, on the outer side of the abutting part 16 and in contact with the abutting part 16. Specifically, one side of the locking block 7 is a slope adapted to the abutting part 16, and the other side is a flat surface. The slope can facilitate fitting with the abutting part 16, and the flat surface is convenient for locking the tie rod. Through the locking block 7, the connection and locking of the connecting piece 8 to the mounting plate 2 can be made more stable.

[0035] Further, in this embodiment, please refer in detail to Figure 3 , the fastening device further includes a sliding rod 5. The sliding rod 5 is a cuboid rod. On the surface of the mounting plate 2 away from the fastening part 6, that is, on the back surface, a pair of oppositely arranged convex parts 3 are formed. The convex parts 3 are hollow and elongated, and the convex parts 3 extend along the length direction of the mounting plate 2. Both ends of the sliding rod 5 are slidably connected to the two convex parts 3 of the same pair, so that the sliding rod 5 can slide reciprocally along the length direction of the convex parts 3. The support mechanism is connected to the sliding rod 5. Thus, the support mechanism can slide along with the sliding of the sliding rod 5, and further the position of the support mechanism can be adjusted, which can be applicable to different construction scenarios and improve the applicability of the device.

[0036] In an alternative embodiment, friction layers are provided at both ends of the sliding rod 5. For example, damping coatings are coated on both ends of the sliding rod 5 to increase the frictional resistance at both ends of the sliding rod 5, so that there is a certain sliding frictional resistance between the sliding rod 5 and the convex parts 3 to prevent the sliding rod 5 from sliding randomly.

[0037] The structure of the sliding connection between the sliding rod 5 and the convex parts 3 has at least the following two implementation manners:

The sliding direction of the sliding rod 5 is limited by the limiting rod 15 to make the sliding of the sliding rod 5 stable. The adjusting screw 13 extends in the same direction as the limiting rod 15. The adjusting screw 13 is rotatably connected to the protruding part 3 so that the adjusting screw 13 can rotate along its circumferential direction. At least one end of the adjusting screw 13 extends outside the protruding part 3 for easy operation.
