Description

Technical Field

[0001] This utility model belongs to the field of window frame sealing technology, specifically relating to a sealing window frame structure used in factory skylights. Background Technology

[0002] To ensure sufficient natural light in factory buildings, multiple skylights are typically installed along the length of the walls at the top. These skylights differ from regular windows in that their purpose is solely for light transmission and they do not require opening or closing mechanisms. Therefore, most common skylights consist only of a frame and a light-transmitting pane. Existing patent application number CN201920346583.1, entitled "A Steel Structure Factory Building for Facilitating Light Transmission," discloses a skylight structure comprising a combined steel frame and a light-transmitting pane. The steel frame has mounting grooves for fixing the light-transmitting pane, enabling rapid installation and meeting the factory's lighting needs. However, this skylight has a drawback: it lacks a necessary sealing structure. Especially during winter and rainy seasons, gaps in the skylight can easily lead to air and water leaks. Therefore, developing a sealed window frame structure for factory skylights is essential to meet practical needs. Utility Model Content

[0003] This utility model aims to solve the problem that existing factory skylights lack the necessary sealing structure, causing air and rain leaks at the gaps in the skylights during winter and rainy seasons. Therefore, it provides a sealed window frame structure for factory skylights.

[0004] A sealed window frame structure for a factory building skylight includes an outer window frame installed at the window in the factory building. A glass retaining frame is installed at both the front and rear ends of the outer window frame. The outer window frame also has N inner window frame components, where N is a positive integer. The multiple inner window frame components are arranged sequentially along the thickness extension direction of the outer window frame, and each inner window frame component is detachably connected to the outer window frame. Each inner window frame component is correspondingly arranged between two adjacent glass panes.

[0005] The inner window frame assembly includes a fixed frame, which is set inside the outer window frame and detachably connected to the outer window frame. An end sealing gasket is fixed to the front and rear sides of the fixed frame, and the front and rear ends of the fixed frame are in close contact with the corresponding glass panes through an end sealing gasket. A circumferential sealing ring is embedded in the inner side wall of the fixed frame. The circumferential sealing ring is detachably connected to the fixed frame through multiple mounting blocks. The circumferential sealing ring has two sealing parts, and both sealing parts on the circumferential sealing ring extend to the outside of the fixed frame and are in close contact with the corresponding glass panes. Each inner window frame assembly is sealed to the corresponding glass pane through the end sealing gasket and the circumferential sealing ring.

[0006] Furthermore, the fixed frame is a regular Z-sided frame, where Z is a positive even number greater than 3. Each side of the fixed frame has a groove machined on its inner side. The circumferential sealing ring is embedded in the Z grooves and is detachably connected to the fixed frame through multiple mounting blocks.

[0007] Furthermore, the circumferential sealing ring includes Z rubber grooves, each rubber groove corresponding to a slot. Adjacent rubber grooves are connected by an arc-shaped rubber sheet to form a ring structure. A rubber ring is fixed to the front and rear ends of the ring structure. The circumferential sealing ring is embedded in the Z slots on the fixed frame through the Z rubber grooves, and the rubber rings at the front and rear ends of the circumferential sealing ring are both set outside the fixed frame. The circumferential sealing ring is correspondingly set with the corresponding glass sheet through the rubber rings.

[0008] The beneficial effects of this application compared to the prior art are:

[0009] This application provides a sealed window frame structure for factory lighting windows. The lighting window adopts a combined frame structure design, which not only meets the lighting needs of the factory but also improves the ease of installation. During installation, the glass pane or light-transmitting pane is installed between two adjacent inner window frame components or between the inner window frame component and the glass pressure frame. The glass pane is clamped and fixed by the inner window frame component and the glass pressure frame to ensure the stability of the glass pane during installation. Compared with the prior art, the sealed window frame structure in this application adopts a double sealing structure design. The gap between the glass pane or light-transmitting pane and the inner window frame component or glass pressure frame is filled by the double sealing of the sealing gasket and sealing ring, which improves the overall sealing performance of the lighting window structure and reduces the occurrence of air and rain leakage in winter or rainy season.

[0025] Specific implementation method one: Combining Figures 1 to 15 This embodiment describes a sealed window frame structure for a factory skylight. It includes an outer window frame 1, which is installed at the window in the factory. A glass retaining frame 2 is installed at both the front and rear ends of the outer window frame 1. The outer window frame 1 also contains N inner window frame components 4, where N is a positive integer. The multiple inner window frame components 4 are arranged sequentially along the thickness extension direction of the outer window frame 1, and each inner window frame component 4 is detachably connected to the outer window frame 1. Each inner window frame component 4 is correspondingly arranged between two adjacent glass panes 3.

[0026] The inner window frame assembly 4 includes a fixed frame 41, which is disposed inside the outer window frame 1 and detachably connected to the outer window frame 1. An end sealing gasket 42 is fixedly connected to the front and rear sides of the fixed frame 41 respectively. The front and rear ends of the fixed frame 41 are in close contact with the corresponding glass sheet 3 through an end sealing gasket 42. A circumferential sealing ring 43 is embedded on the inner side wall of the fixed frame 41. The circumferential sealing ring 43 is detachably connected to the fixed frame 41 through multiple mounting blocks 44. The circumferential sealing ring 43 has two sealing parts, and both sealing parts on the circumferential sealing ring 43 extend to the outside of the fixed frame 41 and are in close contact with the corresponding glass sheet 3 respectively. Each inner window frame assembly 4 is sealed with the corresponding glass sheet 3 through the end sealing gasket 42 and the circumferential sealing ring 43.

[0027] A sealing gasket 21 is fixed to the inner side of the glass frame 2, and the glass frame 2 is sealed to the corresponding glass sheet 3 through the sealing gasket 21.

[0028] The fixed frame 41 is a regular Z-gon frame, where Z is a positive even number greater than 3. Each side of the fixed frame 41 has a groove machined on its inner side. The circumferential sealing ring 43 is fitted into the Z grooves and is detachably connected to the fixed frame 41 through multiple mounting blocks 44.

[0029] The circumferential sealing ring 43 includes Z rubber grooves 431, each rubber groove 431 corresponding to a slot. Adjacent rubber grooves 431 are connected by an arc-shaped rubber sheet 432 to form a ring structure. A rubber ring 433 is fixed to the front and rear ends of the ring structure. The circumferential sealing ring 43 is embedded in the Z slots on the fixed frame 41 through the Z rubber grooves 431, and the rubber rings 433 at both ends of the circumferential sealing ring 43 are set outside the fixed frame 41. The circumferential sealing ring 43 is correspondingly set with the corresponding glass sheet 3 through the rubber rings 433.

[0030] This embodiment provides a sealed window frame structure for a factory building's skylight. It adopts a split-frame design, which facilitates subsequent installation and maintenance. If any component in the frame is damaged, it can be directly replaced. The outer window frame 1 uses different installation methods depending on the factory building structure. For brick-built factories, rivets are used as connecting components, and foam sealant is applied to the joints. Lime and waterproof coating are then applied to the outside of the foam sealant for waterproofing. The glass pressure frame 2 is... The glass frame 2 is a component used for external clamping and sealing of the glass sheet 3. The inner side of the glass frame 2 has a boss that mates with the end of the outer window frame 1 and is fixed to the outer window frame 1 through the boss. The inner side of the boss is the contact surface with the glass sheet 3, and a frame sealing gasket 21 is provided on this contact surface. The boss contacts the glass sheet through the frame sealing gasket 21, thus achieving a seal on the glass sheet. The inner window frame assembly 4 is an important component for clamping and sealing the glass sheet 3. The inner window frame assembly 4 is also a combined structure. The fixing frame 41 is the main body of the inner window frame assembly 4 and is used for interlocking with the outer window frame 1. The frame is connected and serves to support the end sealing gasket 42 and the circumferential sealing ring 43. The end sealing gasket 42 is attached to the front and rear ends of the fixing frame 41 and is used to contact the glass sheet 3. The groove in the fixing frame 41 is used to install the circumferential sealing ring 43. The rubber groove 431 in the circumferential sealing ring 43 is embedded in the groove. The rubber ring 433 in the circumferential sealing ring 43 extends to the outside of the fixing frame 41 as a sealing part and contacts the glass sheet 3 to achieve auxiliary sealing. It is worth noting that the pressure frame sealing gasket 21 has an outwardly extending edge on the side facing the glass sheet 3. The first protrusion and the end sealing gasket 42 are provided with an outwardly extending second protrusion at the edge of the glass sheet 3. The first protrusion and the second protrusion have the same structure. The external sealing ring formed by the first protrusion and the second protrusion or by the two second protrusions is used to seal the gap between the glass sheet 3 and the fixed frame 41. The end sealing gasket 42 and the circumferential sealing ring 43 can achieve complete filling and sealing between the glass sheet 3 and the glass pressure frame 2 and the inner window frame assembly 4, thereby reducing the possibility of rain and air leakage in the skylight structure during the rainy season or winter.

[0031] Z is a positive even number greater than 3, usually 4. This is because, from a cost perspective, rectangular windows are generally the easiest to process and manufacture, and are the most economical for factory buildings.

[0032] Specific Implementation Method Two: Combining Figures 1 to 15 This embodiment further limits the number of inner window frame components 4 in specific embodiment one, with N ranging from 1 to 2. Other components and connection methods are the same as in specific embodiment one.

[0033] In this embodiment, the value of N is 1 to 2, taking into account that existing general window structures are usually equipped with double or triple glass panes in order to achieve the heat preservation effect. When N is 1, it corresponds to the case where two glass panes are arranged in the window. The two glass panes are clamped and fixed by a glass pressure frame 2 and an inner window frame assembly 4, respectively. When N is 2, it corresponds to the case where three glass panes are arranged in the window. The two glass panes near the edge of the three glass panes are clamped and fixed by a glass pressure frame 2 and an inner window frame assembly 4, respectively. The glass pane in the middle of the three glass panes is clamped and fixed by two inner window frame assemblies 4.

[0034] Specific implementation method three: Combining Figures 1 to 15 This embodiment further defines the fixing frame 41 in Specific Embodiment 1. The groove in the fixing frame 41 is a groove with an isosceles trapezoidal longitudinal section, the rubber groove 431 is a groove with an isosceles trapezoidal longitudinal section, and the mounting block 44 is a block with an isosceles trapezoidal longitudinal section. Other components and connection methods are the same as in Specific Embodiment 1.

[0035] Specific implementation method four: Combination Figures 1 to 7 This embodiment further defines the fixing frame 41 and mounting block 44 in specific embodiment one. The fixing frame 41 is detachably connected to the outer window frame 1 by multiple No. 1 connecting bolts 5, and the mounting block 44 is detachably connected to the fixing frame 41 by multiple No. 2 connecting bolts 6. Other components and connection methods are the same as in specific embodiment one.

[0036] In this embodiment, the bottom of each groove in the fixing frame 41 is machined with multiple first-step through holes 412 along the length direction. A threaded connection hole is coaxially machined at the corresponding location of each first-step through hole 412 on the outer window frame 1. The threaded end of the first connecting bolt 5 passes through a first-step through hole 412 in sequence and extends into a threaded connection hole, where it is threadedly connected to the outer window frame 1. The bottom of each groove in the fixing frame 41 is machined with multiple threaded blind holes 411 along the length direction, and each threaded blind hole 411 is offset from a first-step through hole 412. The bottom of the mounting block 44 is machined with multiple second-step through holes 441 along the length direction, and each second-step through hole 441 is coaxially corresponding to a threaded blind hole 411. The threaded end of the second connecting bolt 6 passes through a second-step through hole 441 in sequence and extends into a threaded blind hole 411, where it is threadedly connected to the fixing frame 41.

[0037] The present invention has been disclosed above with reference to preferred embodiments, but it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed structure and technical content to create equivalent embodiments without departing from the scope of the present invention. However, any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.

[0038] Working principle

[0039] The working principle of this application is illustrated below using a rectangular skylight structure with three layers of glass as an example. First, the number of glass panes 3 in a single skylight and the installation position of the inner window frame assembly 4 are determined according to the design requirements of the skylight structure. Based on the installation position of the inner window frame assembly 4, threaded blind holes are machined on the inner wall of the outer window frame 1 to facilitate subsequent fixing of the inner window frame assembly 4. After the preparation work is completed, the glass pressure frame 2 located on the outside of the outer window frame 1 is first embedded in the outer window frame 1, and the outer window frame 1 is bonded and fixed to the glass pressure frame 2 located on its outside using thin foam adhesive. Then, the outer window frame 1 is installed at the corresponding skylight in the factory building. The first glass pane 3 is arranged in the outer window frame 1, ensuring that the first glass pane 3 is embedded in the pressure frame sealing gasket 21 inside the glass pressure frame 2, and the pressure frame sealing gasket 21 seals the first glass pane 3 and the glass pressure frame 2. At this time, the first fixing frame 41 is set in the outer window frame 1, ensuring that one end of the fixing frame 41 is... The sealing gasket 42 and the pressure frame sealing gasket 21 are used to wrap around the edge of the first glass sheet 3. At the same time, the fixing frame 41 and the outer window frame 1 are fixed by multiple No. 1 connecting bolts 5. At this time, the first glass sheet 3 is clamped and fixed in the outer window frame 1 by the fixing frame 41 and the glass pressure frame 2. The end sealing gasket 42 seals the first glass sheet 3 and the fixing frame 41. The No. 2 protrusion on the end sealing gasket 42 and the No. 1 protrusion on the pressure frame sealing gasket 21 jointly seal the first glass sheet 3 and the outer window frame 1. After the fixing frame 41 is fixed, the circumferential sealing ring 43 is correspondingly embedded in the fixing frame 41. The circumferential sealing ring 43 is installed in the fixing frame 41 by four mounting pressure frames 44 and multiple No. 2 connecting bolts 6. The rubber rings 433 on both sides of the circumferential sealing ring 43 extend to the outside of the fixing frame 41. The rubber ring 433 near the outside of the light window is squeezed and sealed with the first glass sheet 3. At this time, the first inner window frame assembly 4 is installed.

[0040] The second glass pane 3 is fitted into the inner side of the first inner window frame assembly 4, ensuring that the second glass pane 3 is fitted into the end sealing gasket 42 inside the first inner window frame assembly 4. The second inner window frame assembly 4 is installed in the outer window frame 1 according to the installation process of the first inner window frame assembly 4. The second glass pane 3 is clamped and fixed in the outer window frame 1 by the first inner window frame assembly 4 and the second inner window frame assembly 4. It is sealed with the fixing frame 41 in the first inner window frame assembly 4 and the second inner window frame assembly 4 by the two end sealing gaskets 42 and the two circumferential sealing rings 43 respectively. The two No. 2 protrusions cooperate to seal the second glass pane 3 and the outer window frame 1. At this point, the installation of the second inner window frame assembly 4 is completed.

[0041] The third glass pane 3 is correspondingly embedded inside the second inner window frame assembly 4, ensuring that the third glass pane 3 is embedded in the end sealing gasket 42 inside the second inner window frame assembly 4. The glass pressure frame 2 located inside the outer window frame 1 is embedded in the outer window frame 1, ensuring that the pressure frame sealing gasket 21 on it cooperates with the end sealing gasket 42 inside the second inner window frame assembly 4 to wrap around the edge of the third glass pane 3. The third glass pane 3 is clamped and fixed in the outer window frame 1 by the second inner window frame assembly 4 and the glass pressure frame 2 located inside the outer window frame 1. The third glass pane 3 is sealed between the pressure frame sealing gasket 21 and the glass pressure frame 2. The third glass pane 3 is sealed between the end sealing gasket 42 and the circumferential sealing ring 43 in the second inner window frame assembly 4. After ensuring that the above sealing structure is squeezed in place and the glass pressure frame 2 located inside the outer window frame 1 is embedded and fixed, the skylight provided in this application is installed.

[0042] This application improves the sealing performance between the glass pane 3 and the outer window frame 1 in the skylight by using a multi-layered combined sealing structure, which can effectively reduce the occurrence of air and rain leakage in the skylight area during winter or rainy season.

[0043] If the internal structure of the window frame needs to be replaced later, it will be removed and replaced from the inside of the skylight. The glass pressure frame 2 located on the inside of the skylight is installed with an interference fit between the glass pressure frame 2 and the outer window frame 1 (to further improve stability, it can be sealed with hot melt adhesive, which can be melted with high temperature when it needs to be replaced later). During the removal, the joint between the glass pressure frame 2 and the outer window frame 1 is pried open several times to separate the glass pressure frame 2 from the outer window frame 1, and the corresponding glass pieces 3 and inner window frame components 4 are disassembled one by one from the inside to the outside. During this process, damaged glass pieces 3 or sealing structures that have reached the end of their service life can be replaced.
