Description

A connection structure of light steel wall and heavy steel beam

technical field

The utility model relates to a connection structure of a light steel wall body and a heavy steel beam.

Background technique

For green prefabricated buildings, according to the existing steel structure construction specifications, heavy steel systems must be used for more than three floors. For buildings with less than three floors, some heavy steel structures or partial heavy steel structures are also used according to the load and design requirements. In this way, there has been a research topic to be solved, that is, the connection technology of light steel walls and heavy steel beams and columns. This is because: as heavy steel, its connection methods are welding, bolting and riveting, while for thin-walled light steel, the main connection method is nailing. Obviously, the light steel wall is fixed on the heavy steel beams and columns, and welding is used, and the thin-walled light steel is too thin to be welded. Bolting and riveting are also not acceptable. If the nail connection is used, the wall or flange of the heavy steel is too thick to be screwed. For this reason, it is proposed to invent a connection technology between light steel walls and heavy steel beams of green prefabricated buildings.

Connection structure of heavy steel beams.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows, a connection structure between a light steel wall and a heavy steel beam, including a steel column, the steel column is connected with a light steel inner wall, and the light steel inner wall is composed of a horizontal keel, The vertical keel is composed of the horizontal keel above the light steel inner wall and the heavy steel beam through the connecting pieces on both sides. The connecting piece is in the shape of angle iron. platform, the right side of the connector fits the left side of the boss, and a magnetic plate is arranged on the transverse keel between the two rows of positioning bosses.

The further improvement of the utility model is that the connector is formed by bending a galvanized steel plate with a length of 250 mm, a width of 100 mm and a wall thickness of 0.5 mm, and the front and side of the connector are both 50 mm.

The further improvement of the utility model is: the front of the connector is connected to the heavy steel beam 7 by welding, and the side of the connector is connected to the transverse keel 3 by installing a hexagon head self-tapping screw in the mounting hole.

The further improvement of the utility model is that: the positioning bosses are arranged equidistantly along the transverse keel direction on the heavy steel beam, the distance between the adjacent positioning bosses is 600 mm, and the distance between adjacent connecting pieces is also 600 mm.

The further improvement of the utility model is that: the side surfaces of the connectors are all connected to the transverse keel 3 through four 5.5×19mm self-tapping screws.

The further improvement of the utility model is that: the thickness of the magnetic plate is the same as that of the boss and the connecting piece, and the thickness of the magnetic plate, the boss and the connecting piece are 0.5 mm.

During construction, the connectors shall be fully welded on the bottom side of the heavy steel beam with on-site argon arc welding at a distance of 600mm, and the position shall make the light steel wall sit in the middle or meet the design requirements, and just block the keel of the wall, and then Use 4 ST5.5×19mm Dacromet self-tapping screws on each side to fix the connecting piece and the wall keel. In this way, the connection and fixation of the light steel wall and the heavy steel beam is completed.

Beneficial effect:

The connecting piece is made of bent galvanized steel plate with a length of 250mm, a width of 100mm, and a wall thickness of 0.5mm. The front and side of the connecting piece are both 50mm. The wall thickness of the connector can not only meet the wall thickness requirements of welding, but also can be nailed together with thin-walled light steel. The utility model has firm connection, simple construction, low cost and fast installation speed. It solves the problem of connecting light steel walls and heavy steel beams of green prefabricated buildings.
