[0005] The technical solution for achieving the purpose of the utility model is: a super span SOM board door hole reinforcing structure, including a square steel pipe hanging column and a concrete layer, the square steel pipe hanging column is fixed with the bottom of the upper concrete layer, and further including;

[0006] The square steel pipe beam is fixedly connected with the bottom end of the square steel pipe hanging column.

[0007] The square steel pipe door frame column is fixed with the upper and lower layer concrete of the wall surface where the door hole is located.

[0008] The SOM board is fixed between the upper and lower layer concrete through the square steel pipe beam and the square steel pipe door frame column.

[0009] In some embodiments, the concrete layer on the upper and lower sides of the door hole is provided with an expansion anchor, the square steel pipe hanging column is fixedly connected with an anchor plate, and the top end of the square steel pipe hanging column is fixed with the upper concrete layer through the anchor plate and expansion bolts.

[0010] In certain embodiments, the upper and lower ends of the square steel pipe door frame column are also fixedly connected with anchor plates, the top end of the square steel pipe door frame column is fixed with the upper concrete layer through the anchor plate and expansion bolts, and the bottom end of the square steel pipe door frame column is fixed with the lower concrete layer through the anchor plate and expansion bolts.

[0011] Compared with the prior art, the present application has the following advantages:

[0012] The square steel pipe hanging column, the square steel pipe lintel and the square steel pipe door frame column replace the concrete structure column, a series of processes such as formwork setting are not needed during door hole reinforcement, the construction is convenient, and the square steel pipe does not need to be maintained after construction, so that subsequent SOM plate installation work can be directly carried out, the process is beneficial to interpenetration, and the construction period is greatly shortened.

[0013] The problem that the process is complicated and the construction period is prolonged due to the need of designing a large concrete lintel to ensure stability in the existing large-size door hole reinforcement project is solved. BRIEF DESCRIPTION OF DRAWINGS
