Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building curtain wall, and particularly relates to an open curtain wall. BACKGROUND

[0002] The building curtain wall is a building envelope or decorative structure which is composed of a supporting structure system and a panel, has a certain displacement capacity relative to the main structure, and does not share the action of the main structure. The building curtain wall is divided into closed and open types according to the sealing form.

[0003] The open curtain wall is a curtain wall structure in which the curtain wall panels are not glued to each other. The open curtain wall is derived from the principle of ventilation convection. The air layer behind the curtain wall panels can flow smoothly through the slits, thereby achieving good heat insulation and sound absorption effects. In the traditional open curtain wall (such as an aluminum plate curtain wall), a gap exists between the adjacent curtain wall panels, and therefore, secondary waterproofing is usually performed behind the curtain wall panels, such as installing a waterproof aluminum plate between the keel and the curtain wall panel. This secondary waterproofing method consumes a large amount of materials and labor, has a complex construction process, a long construction period, and a relatively high maintenance cost. SUMMARY

[0004] The present application aims to provide an open curtain wall which at least solves one of the problems caused by the secondary waterproofing of the existing open curtain wall.

[0005] To achieve the above-mentioned purpose, the present application provides an open curtain wall, comprising:

[0006] A plurality of connecting sub-frames are arranged on the curtain wall keel in the horizontal and vertical directions. The connecting sub-frames are closed frames formed by a plurality of support arms connected end to end. A drain groove is formed in the outer side of each support arm in the axial direction. The drain grooves of the support arms of the connecting sub-frames are connected to each other.

[0007] A plurality of curtain wall panels are arranged on each connecting sub-frame in the horizontal and vertical directions. A gap exists between the adjacent two curtain wall panels, and the gap is connected to the drain groove of the connecting sub-frame.

[0008] Optionally, the two connecting sub-frames arranged side by side in the vertical direction are a first connecting sub-frame and a second connecting sub-frame. The first connecting sub-frame is located above the second connecting sub-frame.

[0009] The top end of the second connecting sub-frame is fixedly connected to the curtain wall keel and forms a clamping groove opening upward with the curtain wall keel. The bottom end of the first connecting sub-frame is partially clamped in the clamping groove.

[0010] Optionally, gaps between two adjacent curtain wall panels on the first and second connecting sub-frames are provided with first decorative buckles.

[0011] Optionally, first accommodating grooves are formed on opposite sides of the first decorative buckles, and first waterproof adhesive strips are arranged in the first accommodating grooves and abut against side walls of the curtain wall panels.

[0012] Optionally, the two curtain wall panels arranged side by side in the transverse direction are a first curtain wall panel and a second curtain wall panel, and the open curtain wall further comprises a pressing block, the pressing block is located at a gap between the first curtain wall panel and the second curtain wall panel and extends into two adjacent drainage grooves of the connecting sub-frames at two ends, and the two ends of the pressing block are tightly fixed with the drainage grooves.

[0013] Optionally, a second decorative buckle is arranged at the gap between the first curtain wall panel and the second curtain wall panel, the second decorative buckle is located on the outer side of the pressing block and is buckled with the pressing block.

[0014] Optionally, second accommodating grooves are formed on opposite sides of the first and second curtain wall panels, and second waterproof adhesive strips are arranged in the second accommodating grooves and abut against side walls of the first or second curtain wall panels.

[0015] Optionally, the outer edge of the support arm is provided with a positioning groove, and the end of the curtain wall panel is at least partially clamped in the positioning groove.

[0016] Optionally, the joint between the two adjacent support arms is filled with sealing glue.

[0017] Optionally, the lower surface of the curtain wall panel is further provided with a flow resistance groove, and the flow resistance groove is recessed inward relative to the curtain wall panel.

[0018] In the open curtain wall provided by the application, at least one of the following beneficial effects is achieved:

[0019] 1) By using the connecting sub-frame to install and fix the curtain wall panel, and by forming the drainage groove on the connecting sub-frame to naturally drain water, the connecting sub-frame has the functions of installation and drainage, compared with the traditional open curtain wall, it is not necessary to do secondary waterproofing, which greatly saves the material and labor cost of secondary waterproofing, and the construction is simple and the construction period is short.

[0020] 2) The gap between the adjacent two curtain wall panels is provided with a decorative cover, the decorative cover is provided with a receiving groove on the opposite sides of the two curtain wall panels, and a waterproof rubber strip is arranged in the receiving groove. The waterproof rubber strip can be used as the first waterproof structure of the open curtain wall to prevent rainwater from entering the gap between the adjacent two curtain wall panels;

[0021] 3) The rainwater flowing along the curtain wall panel can be further prevented from entering the gap between the adjacent two curtain wall panels arranged vertically by arranging the flow resistance groove on the lower surface of the curtain wall panel, thereby improving the waterproof performance.
