Description

Technical Field

[0001] The present invention relates to the technical field of stone curtain walls, in particular to a stone replacement device for existing curtain walls. Background Art

[0002] Butterfly-lock stainless steel hangers are common in existing stone curtain walls. When replacing stone panels in such structures, the replacement stone is blocked by the butterfly-lock stainless steel hangers above and below the stone, making installation difficult. Many construction workers simply install straight or angled stainless steel hangers behind the stone, turning the replaced stone into a time bomb hanging over the city, threatening to cause a falling stone and injure someone at any moment.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0026] A stone replacement device for an existing curtain wall, the device is used to install the stone 1 to be replaced on the curtain wall, and its structure is as follows Figure 1 As shown, it includes a bottom supporting mechanism 2 and a top locking mechanism 3, which are respectively installed on the transverse keel 4 of the curtain wall, and the transverse keel 4 is fixed on the column 5 of the curtain wall. The bottom of the stone 1 to be replaced is rotatably connected to the bottom supporting mechanism 2. After the stone 1 to be replaced is installed on the bottom supporting mechanism 2, the top of the stone 1 to be replaced is rotated to the top locking mechanism 3, and the top locking mechanism 3 locks the top of the stone 1 to be replaced to complete the replacement of the curtain wall stone.

[0027] The structure of the bottom support mechanism 2 is as follows Figure 2 As shown, the bottom pivot hanger 201 and the bottom hanger base 202 are fixed to the transverse keel 4 via a bolt assembly. One end of the bottom pivot hanger 201 is fixedly connected to the bottom of the stone 1 to be replaced, and the other end is rotatably connected to the bottom hanger base 202. The connection between the bottom pivot hanger 201 and the bottom hanger base 202 is specifically a rotating assembly consisting of a rotating shaft and an arc-shaped groove. The bottom hanger base 202 is also provided with a stone stopper 2021 for limiting the position of the stone 1 to be replaced.

[0028] The structure of the top locking mechanism 3 is as follows Figure 3As shown in the figure, it includes a top hanging piece 301, a top hanging piece base 302, and a top slot profile 303. One end of the top hanging piece 301 is fixed to the top of the stone 1 to be replaced, and the other end is provided with a first locking piece. One end of the top hanging piece base 302 is connected to the top slot profile 303 by screws, and the other end is provided with a second locking piece. The top slot profile 303 is fixed to the horizontal keel 4 through a bolt assembly. After the top hanging piece 301 rotates with the stone 1 to be replaced to the position of the top hanging piece base 302, the second locking piece on the top hanging piece base 302 cooperates with the first locking piece on the top hanging piece 301 to lock and fix the stone 1 to be replaced. In this embodiment, the first locking piece is a "冂"-shaped locking piece, and the second locking piece is a "7"-shaped locking piece.

[0029] The top slot profile 303 is provided with a slot for fixing the nut. The top hanging piece base 302 is rotationally connected to and fixed to the top slot profile 303 through the cooperation of screws and nuts.

[0030] The stone replacement device is further provided with a gasket 6 for adjusting the height difference between the bottom hanging piece base 202 or the top slot profile 303 and the horizontal keel 4. The gasket 6 is arranged between the bottom hanging piece base 202 or the top slot profile 303 and the horizontal keel 4.

[0031] The bottom rotating shaft hanging piece 201 and the top hanging piece 301 are respectively pre-installed at the bottom and top of the stone 1 to be replaced.

[0032] The working principle of the stone replacement device in this embodiment is as follows:

[0033] First, pre-assemble the stone 1 to be replaced with the bottom rotating shaft hanging piece 201 and the top hanging piece 301.

[0034] Subsequently, place the bottom rotating shaft hanging piece 201 into the semi-circular part of the bottom hanging piece base 202, and the stone 1 to be replaced can rotate around the center of the semi-circular part of the bottom hanging piece base 202.

[0035] Then, place the stainless steel nut into the slot of the top slot profile 303 from the end of the top slot profile 303, and move the stainless steel nut to a position about 30 mm away from the end of the top slot profile 303. After the stainless steel inner hexagon screw is pre-passed through the round hole of the top hanging piece base 302, screw it into the stainless steel nut, and do not tighten it first.

[0036] Figure 4 The stainless steel inner hexagon screw is not tightened, and the top hanging piece base 302 is in a natural hanging state. After扶正更待更换石材1 (it seems there is an incorrect expression here, assuming it should be "After straightening the stone 1 to be replaced"), the top hanging piece 301 is in Figure 4 the position shown in the figure. Tighten the stainless steel inner hexagon screw, and the top hanging piece base 302 rotates around the central axis of the stainless steel inner hexagon screw until the top hanging piece base 302 is rotated to Figure 5After the top pendant base 302 is positioned as shown in FIG, the top pendant base 302 is inserted into the groove of the top pendant 301, and the stone 1 to be replaced is installed in place.

[0037] 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 such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
