Specific implementation method

[0020] The following will combine the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on 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.

[0021] Example 1

[0022] Please refer to Figures 1 to 3 As shown, the utility model provides a technical solution, and the specific improvements are as follows:

[0023] An FRP-concrete prefabricated assembly structure, comprising an outer frame 1, side panels 2 are movably arranged on both sides of the inner part of the outer frame 1, a telescopic member 3 is arranged between the two opposite sides of the two side panels 2, the telescopic member 3 comprises two movable plates 31, and an adjustment plate 32 is slidably arranged between the two movable plates 31, the telescopic members 3 are provided with two and are distributed front and back, the top surface of the side panel 2 is provided with a driving mechanism 4 for controlling the forward and backward movement of the telescopic member 3, the driving mechanism 4 comprises a fixedly arranged telescopic member 31, a driving mechanism 4 for controlling the forward and backward movement of the telescopic member 3, and ...

[0024] When the distance between the two telescopic parts 3 is to be adjusted, the operator rotates the screw rod 44, which drives the connecting rod 42 to rotate synchronously. During the rotation of the screw rod 44, the sliding plate 43 can be driven to move upward, and the two L-shaped plates 41 can be driven to slide along the top surface of the side plate 2 through the setting of the two inclined rods 45. The two telescopic parts 3 move synchronously, thereby shortening the distance between the two telescopic parts 3. Similarly, controlling the screw rod 44 to reverse makes the distance between the two telescopic parts 3 longer. ​
