Description

Technical Field

[0001] The utility model relates to the technical field of stone curtain walls, in particular to a device for replacing damaged stone curtain walls. Background Art

[0002] The existing stone curtain wall dry hanging system, when the stone curtain wall is damaged, needs to maintain the original curtain wall style, without changing the curtain wall size and glue joint size. The existing method of replacing the curtain wall single piece is difficult to implement.

[0003] A common way to replace damaged stone curtain walls is to use curtain wall panels that are about 10mm smaller than the original curtain wall height, and dry-hang them to the original curtain wall system by back bolts. The disadvantage of this method is that the glue joint is larger than the original curtain wall, which is not beautiful. Secondly, when there is negative wind pressure upward and outward, there is a risk of debonding of the stone curtain wall and stone falling off. Summary of the invention

[0004] In order to solve the above-mentioned problem, the present application provides a damaged stone curtain wall replacement device.

[0005] The present application is implemented through the following technical scheme: a damaged stone curtain wall replacement device, which is used to install the stone to be replaced on the curtain wall, and is characterized in that the damaged stone curtain wall replacement device includes a lock, a hanger, and a back bolt; the lock is installed on the original or newly added vertical keel; the stone to be replaced is connected to the back bolt; the back bolt is connected to the hanger; the hanger is connected to the hook in the lock; after the replacement stone is installed with the back bolt, the hanger and the hook in the lock, the horizontal part of the hook is horizontally pushed into the horizontal cavity, and after the lock tongue completely falls into the lock tongue hole B of the hook, the hook is locked to complete the locking and replacement of the stone curtain wall.

[0006] Preferably, the end plate and limit block is L-shaped.

[0007] Preferably, the lock tongue is in the shape shown in FIG. 6 , and the lock tongue hole A of the end plate and limit block, the hook lock tongue hole B, and the horizontal keel lock tongue hole C are adapted to the lock tongue.

[0008] Preferably, the hook is L-shaped, having a horizontal portion and a vertical portion, and the horizontal portion has a square bolt hole B.

[0009] Preferably, the lock housing is connected to the end plate and limit block by countersunk bolts; the end plate and limit block, the cushion block and the horizontal keel are connected by bolts.

[0010] Preferably, the lock tongue cooperates with the lock tongue hole A of the end plate and the limit block, and the lock tongue hole C of the horizontal keel to limit the hook from slipping out backwards; the vertical part of the end plate and the limit block limits the hook from being pushed forward excessively;

[0011] Compared with the prior art, this application has the following beneficial effects:

[0012] The hook of the present application can move in both directions relative to the lock body, and has a fixing effect after being locked, which is convenient for replacing stones and controlling the installation accuracy, while preventing the stones from falling out. The application of the present application does not change the size of the replaced stones and does not reduce the thickness of the replaced stones.

[0013] This application can ensure that the accuracy of the stone glue joints does not change after replacement.

[0014] This application is easy to replace, can be installed horizontally, and is suitable for the curtain wall dry hanging system, with high construction efficiency and low construction cost.

[0015] The replacement system applicable to the present application can perform equal strength connection, effectively ensuring the accuracy and safety of stone replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Installation and replacement of stone: install the vertical part of hook 16 on hanger 2; find horizontal cavity 174, align the horizontal part of hook 16 with horizontal cavity 174, push horizontally until lock tongue 113 completely falls into the range of lock tongue hole B 162, lock, lock the hook, lock the stone, and make the surfaces of new and old stones flush.

[0041] Glue and seal: Inject silicone sealant 7 into the gap between the new and old stones to seal.

[0042] It is worth noting that one piece of stone is equipped with 4 locks 1, and the 4 locks 1 are arranged in pairs up and down.

[0043] The hook 16 of the present application can effectively lock after the lock tongue falls, control the forward and backward movement of the stone, facilitate the installation of new stone and control the accuracy; can effectively prevent the stone from falling outward and recessing inward; the present application is simple to install, easy to use, and can maintain the same style as the original stone curtain wall.

[0044] The above specific implementation methods further illustrate the purpose, technical solutions and beneficial effects of the present application in detail. It should be understood that the above are only specific implementation methods of the present utility model and should not be used to limit the protection scope of the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
