Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of curtain wall construction, in particular to a curtain wall keel and a curtain wall construction method. BACKGROUND

[0002] The building curtain wall refers to the load-bearing outer wall of the building, which is usually composed of panels (glass, metal plate, stone plate, ceramic plate, etc.) and the supporting structure behind it. The existing low-rise buildings mostly adopt the design method of combining glass curtain walls and panel curtain walls. The fixed glass curtain wall between floors and the panel curtain wall installed on the outer wall of the floor can be both beautiful and practical. The panel curtain wall needs to be fixed on the building outer wall through the curtain wall keel. The traditional curtain wall keel is mostly clamped on the outer wall of the floor, and the top of the top layer curtain wall keel is mostly connected to the upper part of the building structure through anchor bars. The anchor bars are easy to damage the insulation layer structure, affecting the building insulation effect. If the top layer curtain wall keel is directly fixed to the top of the building, the self-weight of the keel is large, which is easy to deform, and the bearing capacity of the embedded part is higher, and the cost is higher. SUMMARY

[0007] Step two, calibrate the curtain wall design model by on-site measurement.

[0008] Step three, encode each curtain wall, main keel and secondary keel in the curtain wall design model, precast the curtain wall according to the curtain wall design model, and manufacture the main keel and the secondary keel on site.

[0009] Step four, according to the set code in the curtain wall design model, pre-weld and fix each main keel and the corresponding secondary keel on the ground.

[0010] Step five, hoist the main keel and the secondary keel of the top layer to the corresponding positions on the top of the building outer wall, and fix the top of each main keel of the top layer to the bottom of the top layer concrete beam, and fix the bottom of each main keel of the top layer to the lower structure of the top layer main keel.

[0011] Step six, weld and fix the adjacent secondary keels of the top layer.

[0012] Step seven, the main keel and the secondary keel of the remaining layers are hoisted to the corresponding positions of the building outer wall in sequence, and the adjacent secondary keels of the same layer are welded and fixed;

[0013] Step eight, according to the code set in the curtain wall design model, the curtain wall is installed on the corresponding secondary keel.
