Description

Technical Field

[0001] The present invention relates to a building structure, in particular to a unit curtain wall. Background Art

[0002] At present, most curtain wall projects use T-shaped steel as the keel (columns and beams) for the first-floor glass curtain walls, skylights, or curtain walls with larger spans, because aluminum profiles are not strong enough as columns to ensure that the strength meets the force calculation. The existing method often uses two pieces of steel plates welded together. If there are decorative strips on the outside or if the steel plates need to be connected on the outside, welding is the only option. The disadvantage of this method is that the welding and positioning of the connecting steel plates is cumbersome and time-consuming, and the thin surface of the steel plates is deformed more frequently during welding, which is difficult to correct. The welding method may also cause problems such as missing welds at the welding position, causing safety issues. Summary of the Invention

[0003] The purpose of the present invention is to provide a unit curtain wall, and the technical problem to be solved is to reduce the welding process, avoid deformation problems caused by welding, improve the safety factor and reduce costs.

[0004] To solve the above problems, the present invention adopts the following technical solutions: A unit curtain wall comprises a unit curtain wall panel, a column for connecting and fixing the unit curtain wall panel, and a secondary keel connected and fixed to the column by a bolt assembly, the secondary keel is composed of two symmetrically arranged sub-keels spliced ​​together, the sub-keel comprises a connecting plate for connecting the column and a wing integrally formed with the connecting plate, the wing is arranged on one side edge of the connecting plate and aligned, the connecting plate is provided with a first connecting portion on the side having the same wing, the first connecting portion is provided with a first connecting through-hole, the side surfaces of the connecting plates of the two sub-keels away from the wing are abutted against each other, the side edge of the connecting plate away from the first connecting portion is provided with a second connecting portion arranged perpendicular to the connecting plate, the second connecting portion is provided with a second connecting through-hole, a slot is provided on the side of the column opposite to the secondary keel, the slot is arranged opposite to the first connecting portion, and a third connecting through-hole connected to the first connecting through-hole is provided on the groove wall of the slot opposite to the two side surfaces of the first connecting portion, the first connecting portion is connected and fixed to the slot after passing through the first connecting through-hole and the third connecting through-hole by the bolt assembly.

[0005] Furthermore, the surface of the first connecting portion is parallel to the surface of the connecting plate.

[0006] Furthermore, the first connecting portions are sequentially spaced apart along the length direction of the connecting plate to form a serrated shape.

[0007] Furthermore, the first connection portions are arranged at equal intervals.

[0008] Furthermore, the width of the slot is equal to the thickness of the first connecting portion.

[0009] Furthermore, the surfaces of the two connecting plates of the two sub-keels on one side thereof are respectively provided with teeth, and the teeth on the two connecting plates are adapted to be connected.

[0010] Compared with the prior art, the present invention adopts a secondary keel composed of two symmetrically arranged sub-keels. The connecting plate and the wing of each sub-keel are integrally formed. After being spliced ​​together, they are connected and fixed to the slots corresponding to the columns through a bolt assembly. Since there is no welding part in the secondary keel, the deformation is small and the insertion accuracy of the secondary keel is guaranteed. The above-mentioned structure can also reduce the cost of welding materials and labor costs and improve the safety factor. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 、 Figure 2 and Figure 3 As shown, the present invention discloses a unit curtain wall, comprising a unit curtain wall panel 1, a column 3 for connecting and fixing the unit curtain wall panel 1, and a secondary keel 2 connected and fixed to the column 3 by a bolt assembly. In the present invention, the connection between the secondary keel 2 and the building exterior wall adopts an anchor 4 provided on a concrete or steel keel, and the secondary keel 2 and the anchor are connected by a conventional connection method, such as bolt connection; the connection between the column 3 and the unit curtain wall panel 1 adopts the existing technology, which is not specifically limited here, wherein:

[0016] The secondary keel 2 is composed of two symmetrically arranged sub-keels 21 spliced ​​together. The sub-keel 21 includes a connecting plate 22 for connecting to the column 3 and a wing 23 integrally formed with the connecting plate 22. The wing 23 is arranged on one side of the connecting plate 22 and aligned with the edge. The connecting plate 22 is provided with a first connecting portion 24 on the same side as the wing 23, so that the cross-section of the sub-keel 21 is T-shaped; the first connecting portion 24 is provided with a first connecting through hole 25, which passes through the opposite two sides of the first connecting portion 24.

[0017] The surfaces of the connecting plates 22 of the two sub-keels 21 away from the winglets 23 are in contact with each other;

[0018] A second connecting portion 26 is provided at a side edge of the connecting plate 22 away from the first connecting portion 24, and a second connecting through hole 27 is provided on the second connecting portion 26. The connecting plate 22 is fixed to the anchor through the second connecting through hole 27 on the second connecting portion 26; a slot 31 is provided on the side of the column 3 opposite to the secondary keel 2, and the slot 31 is arranged opposite to the first connecting portion 24, and the width of the slot 31 is equal to the thickness of the first connecting portion 24; a third connecting through hole 32 is provided on the groove wall opposite to the two side surfaces of the first connecting portion 24 on the slot 31, and the first connecting portion 24 is connected and fixed to the slot 31 after passing through the first connecting through hole 25 and the third connecting through hole 32 by a bolt assembly. Specifically, the screw of the bolt assembly passes through the third connecting through hole 32 on one side, the first connecting through hole 25, and the third connecting through hole 32 on the other side in turn, and is threadedly connected to the nut of the bolt assembly to achieve tightening.

[0019] like Figure 3 As shown, grooves 33 are respectively provided on both sides of the column 3 at the third connecting through hole 32, and the grooves 33 are used to facilitate the assembly of the bolt assembly.
