When the linear sectional door is fully retracted, each section of the door structure can be overlapped in parallel and located in the door opening, occupying a small space and width, which can effectively save space and width in the application site. It is widely used at the entrances and exits of large places such as enterprises, factories, and schools.

[0003] There is no pre-fixed component between the upper beam structure and the column of the existing sectional door. When installing the upper beam and the column, one hand is required to stabilize the column and the upper beam, and then use bolts to tighten them, which is time-consuming and makes the installation work inefficient. In addition, the installation accuracy cannot be guaranteed, which affects the overall performance. Therefore, it is necessary to design a pre-fixed structure that can make the installation between the upper beam and the column faster and more convenient, thereby increasing work efficiency.

[0006] The utility model further arranges a clamping block on the elastic sheet, and a groove matched with the clamping block is arranged on the outer side of the clamping hole. When the contraction section is plugged into the clamping hole, the clamping block on the elastic sheet abuts in the groove.

[0007] The utility model is further configured as follows: a thread is arranged on the inner side of the elastic sheet, and a plurality of convex sheets in a circumferential array are arranged on the outer side of the elastic sheet, wherein the convex sheets are used to increase the connection strength between the upper beam and the column after the expansion shaft is expanded.

[0008] The utility model is further configured as follows: sliding grooves are arranged on both sides of the mounting plate, and a matching sliding block is arranged on the auxiliary connector.

[0009] The utility model is further configured as follows: a spring is arranged in the mounting hole, one end of the spring abuts against the end surface of the expansion shaft, and the other end of the spring abuts against the auxiliary connector.
