[0002] Formwork is the installation of formwork, which is different from supporting formwork. Before the construction of formwork engineering, the formwork support system should be designed, calculated and the supporting nodes should be drawn. Common formworks include cushion formwork, tall formwork, rigid frame formwork, etc. With the development of the construction industry, there are more and more high-rise large buildings, and corridors between large-span buildings are also common buildings. When erecting corridors, corridor formwork is required for support.

[0003] The corridor formwork usually uses the main beam as the basic support. The main beam is usually a whole I-beam. During installation, the I-beam that is longer than the building span needs to be hoisted, and the two ends of the I-beam are respectively inserted into the corresponding holes on the building, and then the formwork is built based on this. Since the length of the I-beam is greater than the building span, it is difficult to plug and install during installation, which increases the difficulty of construction. Utility Model Content

[0006] Furthermore, both ends of the crossbeam are provided with a first through hole, and both ends of the bottom of the crossbeam are provided with symmetrically arranged slots.

[0007] Furthermore, the mounting end includes an I-beam column, one end of the I-beam column is fixedly connected to an end plate, one end of the end plate is fixedly connected to a U-shaped seat, a bolt for connecting the crossbeam is provided in the middle of the U-shaped seat, the bolt passes through the corresponding first through hole, and the middle of the I-beam column is provided with second through holes distributed equidistantly.

[0008] Furthermore, one end of the end plate is symmetrically fixedly connected with an extension plate, and the two extension plates are respectively fixedly welded to two sides of the I-beam column.

[0009] Furthermore, a clamping strip engaged with the clamping slot is fixedly connected to the bottom end of the inner wall of the U-shaped seat.
