A curtain wall waterproof structure

Abstract

This utility model belongs to the field of door and window technology and discloses a waterproof curtain wall structure, including a central column, a window frame, a window sash, and hinges. The window frame is installed on the central column, and the window sash is connected to the window frame via hinges. All three components—the central column, window frame, and window sash—are equipped with thermal break structures. A groove is machined into the top of the inner frame, and a step is machined into the outer wall of the outer frame. The window sash is separated into an inner sash frame and an outer sash frame by the thermal break structure. A clearance space for installing the hinge is machined into the bottom of the inner sash frame, and the hinge is installed within this clearance space and connected to both the inner frame and the inner sash frame. A downwardly extending baffle is installed on the outer wall of the outer sash frame, and a sealing strip is installed on the bottom side wall of the baffle to abut against the side wall of the step on the outer frame. This utility model installs the hinge between the inner sash frame and the inner frame, and provides clearance space on the inner sash frame to accommodate the hinge, thereby increasing the hinge installation height. Simultaneously, the step on the outer frame facilitates water drainage, thus reducing corrosion of the components.

Description

Technical Field

[0001] This utility model belongs to the field of door and window technology, and specifically relates to a waterproof structure for curtain walls. Background Technology

[0002] The drainage structure of curtain wall windows is a key design element in ensuring the waterproofing performance of a building facade. Its key aspects lie in water diversion and sealing to prevent rainwater from seeping into the interior or curtain wall cavities. Since awning windows need to be opened for ventilation, the focus of curtain wall waterproofing is primarily at the location of these windows. Figure 1 As shown, the existing window sills and curtain wall frames are relatively large, so the hinges are also installed between the frames. However, the existing window sills and curtain wall frames have relatively straight cross sections. After rainwater seeps into the space between the window sills and the curtain wall frames, it cannot be drained in time due to structural limitations and tends to accumulate between the window sills and the curtain wall frames. Over time, this will cause corrosion of the screws and hinges and affect their service life. Therefore, it is necessary to improve the structure of the existing curtain wall windows. Utility Model Content

[0003] The purpose of this invention is to solve the problems in the background technology and provide a waterproof curtain wall structure. This curtain wall structure improves the existing hinge installation position and profile structure, which can reduce rainwater accumulation and thus improve the waterproof effect.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A waterproof curtain wall structure includes a central column, a window frame, a window sash, and hinges. The window frame is mounted on the central column, and the window sash is connected to the window frame via hinges. All three components—the central column, window frame, and window sash—are equipped with thermal break structures. The central column is divided into an inner column frame and an outer column frame via the thermal break structure. The window frame is divided into an inner frame body and an outer frame body via the thermal break structure. The top of the inner frame body has an upward-protruding groove for mounting the hinge. The outer wall of the outer frame body has a step. The window sash is divided into an inner sash frame and an outer sash frame via the thermal break structure. The bottom of the inner sash frame has a clearance space for mounting the hinge. The hinge is installed within the clearance space and is connected to both the inner frame body and the inner sash frame. The outer wall of the outer sash frame has a downward-extending baffle. A sealing strip is installed on the bottom side wall of the baffle, which abuts against the side wall of the step on the outer frame body.

[0006] The outer wall of the outer fan frame is flush with the outer wall of the outer column frame, and there is a gap between the baffle and the top of the outer column frame.

[0007] The beneficial effects of the curtain wall waterproof structure provided by this utility model are as follows: by installing the hinge between the inner sash frame and the inner frame body, and leaving a clearance space on the inner sash frame to accommodate the hinge, the installation height of the hinge can be increased. At the same time, the steps processed on the outer frame body can facilitate the drainage of accumulated water, thereby reducing the corrosion of accessories. Attached Figure Description

[0013] like Figure 2 , Figure 3As shown, the curtain wall waterproof structure provided in this embodiment includes a central column 1, a window frame 2, a window sash 3, and a hinge 4. The window frame 2 is installed on the central column 1, and the window sash 3 is connected to the window frame 2 via the hinge 4. A thermal break structure 5 is provided on the central column 1, window frame 2, and window sash 3. The central column 1 is separated into an inner frame 11 and an outer frame 12 by the thermal break structure 5. The window frame 2 is separated into an inner frame 21 and an outer frame 22 by the thermal break structure 5. The top of the inner frame 21 is machined with an upwardly protruding slot 23 for mounting the hinge 4, which increases the installation height of the hinge 4. The outer wall of the outer frame 22 is machined with a step 24, which forms a progressively lowering surface on the outer frame 22, facilitating the drainage of water accumulated between the window sash 3 and the window frame 2, thereby reducing the corrosion of the hinge 4 by accumulated water. The window sash 3 is separated into an inner frame 21 and an outer frame 22 by the thermal break structure 5. The inner sash frame 31 and the outer sash frame 32 have a clearance space at the bottom of the inner sash frame 31 for installing the hinge 4. The hinge 4 is installed in the clearance space and is connected to the inner frame 21 and the inner sash frame 31. The clearance space can further increase the space for the hinge 4. At the same time, the hinge 4 is located in the middle between the window frame 2 and the window sash 3, which facilitates the evaporation of water and further reduces the corrosive effect of water accumulation. The outer sash frame 32 has a downward-extending baffle 33 on its outer wall. The bottom side wall of the baffle 33 is equipped with a sealing strip 34 that abuts against the side wall of the upper step 24 of the outer frame 22. The outer wall of the outer sash frame 32 is flush with the outer wall of the outer column frame 12, and there is a gap between the baffle 33 and the top of the outer column frame 12. The flush outer sash frame 32 and the outer column frame 12 can reduce the contact area between the window sash 3 and rainwater, thereby reducing the accumulation of rainwater on the outside of the window sash 3.

[0014] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications and substitutions based on the technical solutions and inventive concepts provided by the present invention should be covered within the scope of protection of the present invention.
