[0023] In the description of the present invention, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0024] The following is combined with Figure 1-7 The utility model is further described.

[0025] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a fixed connection structure of prefabricated components for construction projects, including a prefabricated panel 1, a first connecting panel 2 and a second connecting panel 4, and the four sides of the prefabricated panel 1 are fixedly connected with a connecting sleeve 5 and an insert block 8, and the connecting sleeve 5 and the insert block 8 are arranged opposite to each other.

[0026] In this embodiment, a first socket 6 and a second socket 7 are provided in the connecting sleeve 5, a third socket 9 is provided in the insert block 8, an insert frame 17 is fixedly connected to the outside of the second connecting plate 4, a concave frame 13 is fixedly connected to the outside of the first connecting plate 2, a side cover 3 is detachably fixedly connected to the outside of the concave frame 13, a nut cap 11 is provided in the concave frame 13, a screw 12 is fixedly connected to the outside of the second connecting plate 4, and a through hole is provided at the position of the screw 12 corresponding to the concave frame 13, so that the insert block 8 is plugged into the connecting sleeve 5 through the first socket 6 and is located in the second socket 7. At this time, the third socket 9 coincides with the second socket 7, and then the first connecting plate 2 and the second connecting plate 4 are taken, and the two adjacent prefabricated panels 1 are connected through the enclosure of the first connecting plate 2 and the second connecting plate 4. At this time, the insertion frame 17 passes through the third socket 9 and the second socket 7, thereby locking the insertion block 8 in the connecting sleeve 5, and the screw 12 enters the concave frame 13. By taking the nut cap 11 and the threaded connection with the screw 12, the screw 12 is firmly connected to the concave frame 13, and the first connecting plate 2 and the second connecting plate 4 can be connected and fixed.

[0027] Among them, the first connecting plate 2 is a U-shaped structure, the second connecting plate 4 is a rectangular structure, the area enclosed by the first connecting plate 2 and the second connecting plate 4 is a rectangle, and the outer walls of the first connecting plate 2 and the second connecting plate 4 are fixedly connected with sealing strips.

[0028] In a further design, in this embodiment, a fourth socket 10 is provided on both sides of the outside of the plug block 8, two slides 18 are symmetrically provided in the plug frame 17, and a spring 19 is connected between the slides 18. The outside of the slide 18 is fixedly connected with a snap-on inclined plate 21, and a sliding opening 20 is provided at the position of the snap-on inclined plate 21 corresponding to the outside of the plug frame 17. The plug frame 17 passes through the third socket 9 and the second socket 7, thereby locking the plug block 8 in the connecting sleeve 5. At the same time, the snap-on inclined plate 21 will also be snapped into the third socket 9 under the elastic force of the spring 19 to form a locking structure.

[0029] In order to increase the stability of the connection, a first L-shaped plate 15 and a second L-shaped plate 16 are fixedly connected to the outside of the prefabricated plate 1. The first L-shaped plate 15 and the second L-shaped plate 16 are arranged opposite to each other. The outside of the second connecting plate 4, which corresponds to the first L-shaped plate 15 and the second L-shaped plate 16, are fixedly connected with a conflict block 14. In order to facilitate the conflict of the conflict block 14, the outside of the conflict block 14, the first L-shaped plate 15 and the second L-shaped plate 16 are all provided with arc edges. When the nut cap 11 is turned to connect with the screw 12, the first connecting plate 2 and the second connecting plate 4 can be connected. The connecting plates 4 are squeezed and fixed to each other. At this time, the second connecting plate 4 will also drive the resistance block 14 to resist the first L-shaped plate 15 and the second L-shaped plate 16 respectively. Due to the setting of the arc edge, the first L-shaped plate 15 and the second L-shaped plate 16 tend to approach each other, so that the two adjacent prefabricated panels 1 can be tightened together again. After the first connecting plate 2 and the second connecting plate 4 are spliced ​​together, they are flush with the prefabricated panel 1 in the horizontal and vertical directions, which will not only not affect the appearance, but also will not affect the connection between other prefabricated panels 1 and them.

[0030] The method of using this embodiment is as follows: plug the two adjacent prefabricated panels 1 together, and let the plug block 8 be plugged into the connecting sleeve 5 through the first socket 6 and located in the second socket 7. At this time, the third socket 9 coincides with the second socket 7. Then take the first connecting plate 2 and the second connecting plate 4, and connect the two adjacent prefabricated panels 1 through the enclosure of the first connecting plate 2 and the second connecting plate 4. At this time, the plug frame 17 passes through the third socket 9 and the second socket 7, thereby locking the plug block 8 in the connecting sleeve 5. At the same time, the engaging inclined plate 21 will also be engaged in the third socket 9 under the elastic force of the spring 19 to form a locking structure. The screw 12 enters the concave frame 13, and the screw 12 is firmly connected to the concave frame 13 by taking the nut cap 11 and the threaded connection with the screw 12, so that the first connecting plate 2 and the second connecting plate 4 can be connected and fixed, and then the side cover 3 is taken to seal and fix the concave frame 13; thus, in this embodiment, the connection and fixation between two adjacent prefabricated panels 1 can be conveniently and quickly performed, and the operation is convenient; after the first connecting plate 2 and the second connecting plate 4 are spliced ​​together, they are flush with the prefabricated panel 1 in the horizontal and vertical directions, which not only does not affect the appearance, but also does not affect the connection between other prefabricated panels 1 and them.

[0031] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
