Abstract
Description
Technical Field
[0001] This invention relates to the field of frameless glass curtain walls, and in particular to a visible frame cover that is added to an existing frameless glass curtain wall. Background Technology
[0002] Concealed-frame glass curtain walls are common in existing curtain walls. However, because they rely primarily on silicone structural sealant to bond the glass to the sub-frame, the glass is prone to falling and injuring people when the sealant ages or the bond fails. Therefore, it's necessary to add external covers to the glass to convert it into a safer semi-concealed or exposed-frame glass curtain wall to prevent glass from falling. In existing concealed-frame glass curtain wall structures, the sub-frame is mechanically fixed to the keel using pressure blocks and stainless steel screws or bolts, which is relatively reliable. The gaps between the sub-frame and the keel structure can be utilized to form a mechanical connection using spring clips, and then threaded connections can be used to fix the aluminum alloy pressure plate and covers on the outside of the glass. Summary of the Invention
[0003] The purpose of this invention is to overcome the defects of the prior art by providing an exposed frame cover that can be added to an existing concealed frame glass curtain wall to prevent the glass from falling due to aging of the structural adhesive or failure of the bonding.
[0004] An exposed frame cover is added to an existing concealed frame glass curtain wall. The glass curtain wall includes an aluminum alloy keel, a glass sub-frame, and glass. The glass is connected to the aluminum alloy keel through the glass sub-frame. The exposed frame cover includes an assembly, an internal connector, an external connector, an aluminum alloy pressure plate, and an aluminum alloy cover. One end of the assembly is fixed between the aluminum alloy keel and the glass sub-frame through the internal connector. The aluminum alloy pressure plate is connected to the other end of the assembly through the external connector and is pressed against the glass. The aluminum alloy cover is fastened to the glass by the aluminum alloy pressure plate.
[0005] Preferably, the assembly includes a stainless steel U-shaped groove, a V-shaped spring clip, a stainless steel threaded sleeve, and a nylon washer. The stainless steel threaded sleeve is welded to the bottom of the stainless steel U-shaped groove. The V-shaped spring clip is pressed and inserted into the U-shaped cavity of the stainless steel U-shaped groove. After the protruding part of the V-shaped spring clip pops out at the opening of the stainless steel U-shaped groove, the nylon washer is put onto the outside of the stainless steel threaded sleeve.
[0006] Preferably, the stainless steel U-shaped groove is longer than the V-shaped spring clip, and threaded holes are opened on the stainless steel U-shaped groove at the upper and lower positions of the V-shaped spring clip.
[0007] Preferably, the internal connector is a stainless steel screw, which is screwed into the upper and lower threaded holes of the stainless steel U-shaped groove until the V-shaped spring clips tighten against the glass sub-frame, while the stainless steel screws tighten against the surface of the aluminum alloy keel.
[0008] Preferably, the external connector includes a stainless steel stud and a nut. One end of the stainless steel stud passes through the aluminum alloy pressure plate and is screwed into the stainless steel threaded sleeve. The other end is pressed against the glass by the nut.
[0009] Preferably, a sealing strip is provided at the contact point between the aluminum alloy pressure plate and the glass.
[0010] Preferably, the sealing strip has a sealing adhesive layer.
[0011] Preferably, the aluminum alloy pressure plate and the aluminum alloy buckle cover are connected by a snap-fit connection.
[0012] Compared with the prior art, the present invention has the following advantages:
[0013] 1. The spring clip and threaded connection make operation simple and quick.
[0014] 2. All connections are mechanical, ensuring high reliability.
[0015] 3. The adjustment steps for the stainless steel studs between the two glass seams are simple and convenient for construction.
[0016] 4. No holes need to be drilled in the existing curtain wall keel, avoiding the adverse effects of vibration caused by drilling holes on the curtain wall components. Attached Figure Description

Detailed Implementation
[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.
[0022] The principle of this invention: This invention describes a method for adding a visible frame cover to an existing concealed frame glass curtain wall. The purpose of this invention is to prevent glass from falling due to aging of the structural adhesive or bonding failure by adding a visible frame pressure plate and cover to the outside of the existing concealed frame glass curtain wall through mechanical connection without opening holes in the existing curtain wall keel. This connection method uses a V-shaped spring clip placed in a stainless steel U-shaped groove. After compression, the V-shaped spring clip is placed into the stainless steel U-shaped groove, and the protruding part of the V-shaped spring clip pops out at the opening of the stainless steel U-shaped groove. The stainless steel U-shaped groove is slightly longer than the V-shaped spring clip, and threaded holes are opened at the top and bottom of the V-shaped spring clip. A stainless steel threaded sleeve is welded in the middle of the U-shaped groove, and a nylon washer is placed on the outside of the sleeve. Stainless steel screws are screwed into the threaded holes at the top and bottom of the stainless steel U-shaped groove until the V-shaped spring clip is pressed against the glass sub-frame, and at the same time, the stainless steel screws are pressed against the keel surface. One end of the stainless steel stud is screwed into the threaded sleeve, and the other end is pressed against the aluminum alloy pressure plate by a nut. The contact area between the aluminum alloy pressure plate and the glass is sealed with a sealing strip and then sealed with sealant.
[0023] First, cut off the sealant on the exterior side of the existing hidden frame curtain wall glass 3, and then retighten the bolts or screws connecting the aluminum alloy pressure block 13 and the aluminum alloy keel 1 to ensure that the glass sub-frame 2 is pressed firmly onto the aluminum alloy keel 1.
[0024] The stainless steel U-shaped groove 41, V-shaped spring clip 42, stainless steel threaded sleeve 43, and nylon washer 44 are assembled components. The assembly sequence is as follows: first, weld the stainless steel threaded sleeve 43 to the stainless steel U-shaped groove 41 as a whole; then, press the V-shaped spring clip 42 tightly into the U-shaped cavity of the stainless steel U-shaped groove 41; after the protruding part of the V-shaped spring clip 42 pops out at the opening of the stainless steel U-shaped groove 41, put the nylon washer 44 onto the outside of the stainless steel threaded sleeve 43.
[0025] Insert the assembly from the outside of the glass 3. Protect the end of the glass 3 during insertion to prevent the assembly from scratching the glass 3. After the V-shaped spring clip 42 in the assembly passes the outermost rib of the glass sub-frame 2, the V-shaped spring clip 42 automatically pops open and screws the stainless steel screw into the upper and lower threaded holes of the stainless steel U-shaped groove 41 until the V-shaped spring clip 42 presses against the glass sub-frame 2. At the same time, the stainless steel screw presses against the surface of the aluminum alloy keel 1.
[0026] Screw the stainless steel stud 61 into the stainless steel threaded sleeve 43. Then, fit the aluminum alloy pressure plate 7, with the sealing strip 9 already inserted, onto the stainless steel stud 61. The aluminum alloy pressure plate 7 has pre-drilled holes corresponding to the stainless steel stud 61. If the holes on the aluminum alloy pressure plate 7 are not aligned with the stainless steel stud 61, loosen the stainless steel screws and adjust the position to align the stainless steel stud 61 with the holes on the aluminum alloy pressure plate 7. Then, fit the nut 62 onto the stainless steel stud 61 and tighten it to press the aluminum alloy pressure plate 7 and the sealing strip 9 against the glass 3. Finally, apply sealant to the outside of the sealing strip 9 and fasten the aluminum alloy cap 8.
[0027] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
