The present invention will be described in further detail with reference to the accompanying drawings 1-5: a reconstruction construction structure for an oversized door opening of a building comprises a steel column 1 and a steel beam 2; as shown in fig. 1, a plurality of steel columns are respectively arranged on the inner side and the outer side of the wall body of the door opening to be reconstructed, and one end of each steel column is arranged on the ground/foundation; two steel beams are provided, and two ends of each steel beam are respectively fixed with the upright post or the top of the upright post; both are limited by the tie bars/bolts penetrating through the wall body; a steel base plate is arranged between the steel column 1 and the ground/foundation, the steel base plate is fixed on the ground/foundation, and the end part of the steel column is fixed with the steel base plate; when the device is disassembled, the device is disassembled from two sides to the middle section.

As a preferred embodiment of the present embodiment, as shown in fig. 2, an inclined strut 4 is fixed between a steel column 1 and a steel beam 2, wherein an included angle between the inclined strut 4 and the steel column 1 or the steel beam 2 is 45 °.

As a preferred embodiment of this embodiment, as shown in fig. 3-5, the steel plate 5 is further included, after a hole is drilled in the wall at the bottom of the steel beam 2, the steel plate 5 is placed between the steel beam 2 and the wall above the hole, the upper surface of the steel plate 5 is fixed to the wall through the super glue, and the lower surface of the steel plate 5 is fixed to the steel beam.

According to the size of the modified door opening of the building and the load condition of the upper structure, the structural steel is adopted to implement modification and reinforcement so as to ensure the uniformity of the safety and the function after the modification of the building. For example, in this embodiment, the height of the door opening to be modified is 4200mm, and the specific modification steps are as follows:

1. when a building surface layer is reformed and a door opening is enlarged, selected steel columns 1 (section steel sandwich wall columns) steel backing plates are padded on the ground/foundation on the inner side and the outer side of a wall according to a design drawing, high-strength expansion bolts or high-strength steel planting bar glue are used for fixing the positions, and the next construction is carried out after the bolts are firmly combined with the ground/foundation;

2. drilling a plurality of holes in a steel column 1 of a sandwich wall along the length direction of the steel column according to a design drawing, welding and positioning the bottom of the steel column 1 and a steel backing plate, forming holes in the wall bodies on two sides of the steel column 1, cleaning residues in the holes of the wall bodies, coating bar planting glue on tie bars 3 to fix the steel column 1 (the section steel sandwich wall column), and so on;
