Compared with prior art, the utility model has technique effect beneficial below：
The utility model forms integrally-built main fulcrum force by being used as three square steel on summit, by corresponding
Plate-side plate welding forms entirety, L-shaped on section, maintains the overall stability under loading of structure and uniformly, and due in corner
Place is directly by the use of the second square steel as transferring, therefore its globality is influenceed and transmission by the second square steel；Due to square steel in itself
Structural stability so that it uniformly can be allocated and transmit in the stress of corner, avoid other connection members
That brings is unstable, and all positions that is welded to connect are completed in same plane, the connection position without additional processing between Different Plane
Put, bearing capacity is strong, and globality is strong, and ductility is good, and connection is firm, and convenient and quick construction is efficient, only needs to be poured into a mould at the scene
Operation.
Further, by the reasonable setting to cavity length, its stress and Multicarity can be ensured on to greatest extent
The uniformity in interior each space, realize that stress and carrying are uniform.
Further, by the waist round hole of setting, each cavity can be connected as one by the concrete of cast, improved
Its overall performance；And preferably the toughness in junction can be strengthened, and can prevent outside by the setting of steel fibre
The corrosion of structure.
Further, globality of the coupled column on L-type section can further be improved by the stiffener of setting,
The transmission and distribution of both sides strength are better met, overall rigidity and toughness are greatly improved.
