The newly-added side steel column, the newly-added angle steel column, the newly-added side steel beam and the roof steel inner ring beam are made of I-shaped steel, channel steel, H-shaped steel or any combination of the I-shaped steel, the channel steel and the H-shaped steel.
A square steel base plate with the thickness of 10mm and the side length of 50mm is padded between the nut of the M20 bolt and the outer wall.
The length of the screw is at least 200mm longer than the total thickness of the newly-added steel beam and the outer wall.
Old local-style dwelling houses adopt interior steel frame reinforced structure, its characterized in that: the method comprises the following steps:
firstly, according to a design drawing, a steel column foundation is prefabricated at the position where a newly-edged steel column and a newly-angled steel column are installed on the first floor of an original building;
step two, installing a newly-added side steel column and a newly-added angle steel column on the basis of the reserved steel column of the original building;
thirdly, arranging a roof steel inner ring beam at the bottom of the roof of the original building, respectively welding the roof steel inner ring beam with the newly-added side steel column and the newly-added angle steel column head, confirming that the position of the roof steel inner ring beam can completely cover and bear all loads of the roof, and simultaneously enabling the roof steel inner ring beam to be tightly attached to the roof and fixing the roof steel inner ring beam with the original roof;
installing newly-added side steel beams on the periphery close to the inner wall of the outer wall according to a design drawing, and respectively welding the newly-added side steel beams with a newly-added side steel column and a newly-added angle steel column;
step five, reserving screw mounting holes on the newly added edge steel beam according to a certain interval, forming holes on the outer wall corresponding to the holes, penetrating the screws through the holes of the newly added edge steel beam and the holes of the outer wall, mounting a base plate, and fastening by nuts;
and step six, plugging the roof and the steel inner ring beam of the roof by using a metal wedge key, so that the load of the roof is completely dropped on the new inner frame structural system.
Has the advantages that:
the utility model forms a new structure bearing system-steel structure device by arranging a new edge steel column, a new angle steel column, a new edge steel beam and a roof steel inner ring beam, and can bear all the vertical loads of the original building. The wall body of the original building is only used as the outer enclosure structure of the new structure system. The change of the structural form converts the original wall body bearing into the inner steel frame bearing with better integrity and bearing capacity, reduces the requirements on the old structural wall body, and does not influence the internal use space and the external sensory effect of the old residences. The utility model discloses load system after the conversion adopts interior steel frame structure, because the steel construction has better ductility, plasticity and toughness, and intensity is high, and anti-seismic performance is good, and simple manufacture, construction period advantage such as short have apparent economic benefits and social.
