As a further improvement of the above technical solution:
the locking bolt is in threaded connection with the bottom of the crack groove.
The crack settling groove is a rectangular groove.
A first adhesive tape is arranged between the steel keel and the curtain wall plate.
And a positioning table is arranged at the bottom of the first adhesive tape and is clamped in the crack sinking groove.
A cavity is formed in the first adhesive tape, and a heat insulation piece is arranged in the cavity.
The cavity is provided with a notch which is convenient for the heat insulation piece to be extruded into the cavity.
And a second adhesive tape is arranged between the pressing plate and the curtain wall plate.
The curtain wall plate supporting device is characterized by further comprising a supporting piece, one end of the supporting piece is clamped into the countersunk groove, and the other end of the supporting piece forms a supporting support for the end portion of the curtain wall plate.
The cover plate is covered on the pressing plate and is clamped with the pressing plate.
Compared with the prior art, the invention has the advantages that:
the curtain wall system comprises a steel keel, a curtain wall plate, a pressing plate and locking bolts, wherein a slot extending into the cross section outline of the steel keel is formed in the steel keel, the curtain wall plate is borne on the steel keel, the pressing plate is pressed on the curtain wall plate, the locking bolts penetrate through the pressing plate and are in threaded connection with the slot walls on two sides of the slot, and when the locking bolts are screwed, the pressing plate and the steel keel clamp the curtain wall plate together. During this curtain system installation, fix with steel joist earlier, then bear curtain wall board on steel joist, press the clamp plate again and establish on curtain wall board, wear to establish locking bolt on the clamp plate and with the cell wall threaded connection of crack groove both sides at last, further screw locking bolt, order about clamp plate and steel joist clamp tightly curtain wall board jointly. Compared with the traditional structure, a very small crack groove is formed in the steel keel of the curtain wall system, and the groove walls on the two sides of the crack groove are in threaded connection with the locking bolt, so that on one hand, the number of effective thread turns is increased, and the fastening effect and the anti-pulling capacity are greatly improved; on the other hand, the connecting area of the locking bolt and the steel keel is increased, and the shearing resistance is greatly improved; for the keel structure with a complex cross section, the crack sinking groove of the steel keel is easy to form, and the cost of the steel curtain wall is greatly reduced.
