Description

Technical Field

[0001] This utility model relates to the field of aluminum profile window technology, and in particular to a unitized, fully welded, quick-installation prefabricated window. Background Technology

[0002] Aluminum profile windows are architectural windows assembled with aluminum alloy profiles as the main load-bearing components, combined with glass, hardware accessories, sealing materials, etc.

[0003] In existing technologies, due to factors such as window size and handling, aluminum profile windows are generally installed through on-site assembly: the window frame is formed by assembling thermally broken aluminum alloy profiles at the corners using corner brackets, while the glass, operable sashes, etc., are assembled and fixed inside the window frame. This method has the following drawbacks: First, the window's heat insulation, sound insulation, and sealing performance are greatly affected by the installer's skill level, making it difficult to guarantee the quality of window installation; second, the corner connections of the aluminum alloy profiles using corner brackets are prone to gaps, resulting in poor window aesthetics. Utility Model Content

[0004] To overcome the technical defects of existing aluminum profile windows, such as difficulty in guaranteeing installation quality and poor aesthetics, this utility model provides a unitized, fully welded, quick-installation finished window.

[0005] The unitized, fully welded, quick-installation prefabricated window provided by this utility model includes:

[0006] It includes a window frame subframe, a fixed sash unit panel, and an operable sash unit panel. The window frame subframe is made of multiple aluminum alloy profiles connected by corner brackets. The fixed sash unit panel includes a first frame and a first glass. The operable sash unit panel includes a second frame and an operable sash body. Both the first frame and the second frame are fully welded frames.

[0007] The first frame and the second frame are both connected to the inner side of the window frame sub-frame by spinning parts, and the fixed sash unit plate and the operable sash unit plate cover the entire area of ​​the window frame sub-frame.

[0008] The aluminum alloy profile is provided with mounting cavities extending to both ends. The mounting cavity is open to the interior wall and is equipped with a strip-shaped cover. The mounting cavity wall facing the first frame or the second frame is provided with a clearance opening corresponding to the spinning component. The spinning component includes a snap-fit ​​part and a pressing part. The snap-fit ​​part is slidably snapped into the mounting cavity. The pressing part is rotatably connected to the snap-fit ​​part and can pass through the corresponding clearance opening and press against the first frame or the second frame by rotation.

[0009] Optionally, the cavity wall facing the first frame or the second frame and the cavity wall away from the first frame or the second frame are both provided with retaining strips, and the retaining part is provided with a retaining groove corresponding to the retaining strips.

[0010] Optionally, the snap-fit ​​portion is further screwed with a set screw, and the clamping portion forms a hollow area corresponding to the set screw. The set screw abuts against the cavity wall of the mounting cavity facing the outside to make the snap-fit ​​strip fit with the snap-fit ​​groove to lock the position of the spun part.

[0011] Optionally, the aluminum alloy profile of the window frame sub-frame located on the bottom side is also equipped with multiple height-adjustable leveling components. Each leveling component abuts against the bottom of the fixed sash unit plate or the bottom of the open sash unit plate to achieve leveling through the cooperation of multiple leveling components.

[0012] Optionally, the leveling component includes a bolt vertically inserted into the mounting cavity, the head of the bolt being limited to slide on the cavity wall of the mounting cavity facing the first frame or the second frame to restrict rotation, and a nut being screwed onto the bolt shank, the nut being placed inside the mounting cavity and abutting against the cavity wall of the mounting cavity away from the first frame or the second frame.

[0013] Optionally, the opening fan unit panel may further include a second glass.

[0014] Optionally, the opening fan body includes an opening fan frame and an opening fan glass, wherein the opening fan frame is a fully welded frame.

[0015] Optionally, the fully welded frame includes an outdoor welded integrated frame, an indoor welded integrated frame, and a heat-insulating profile. The heat-insulating profile is disposed between the outdoor welded integrated frame and the indoor welded integrated frame. The outdoor end of the heat-insulating profile is snapped and fixed to the outdoor welded integrated frame, and the indoor end of the heat-insulating profile is fixed to the indoor welded integrated frame by a double-swivel fastener.

[0016] Both the interior-facing end of the thermal insulation profile and the exterior-facing end of the interior welded frame are provided with C-grooves. The double-hook includes a screwing part and fastening parts on both sides of the screwing part. The double-hook is a long strip structure so that it can be rotated to have an installation state smaller than the opening size of the C-grooves and a snap-fit ​​state larger than the opening size of the C-grooves. When the double-hook is in the snap-fit ​​state, the two fastening parts are respectively placed in the C-grooves of the thermal insulation profile and the C-grooves of the interior welded frame, and the screwing part is exposed between the thermal insulation profile and the interior welded frame.

[0017] Optionally, the end of the thermal insulation profile facing the outside is fixed to the outdoor welded integral frame by a sawtooth structure.

[0018] Optionally, the surface of the fastening part facing the C-groove opening is set as an inclined surface so as to gradually press the two sides of the C-groove opening during rotation.

[0019] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0020] 1) The unitized fully welded quick-installation finished window provided by this utility model splits the traditional window frame into two parts: the window frame sub-frame and the frame of the unit panel. In this way, the fixed sash unit panel and the operable sash unit panel can be directly manufactured and assembled in the factory. On-site workers only need to assemble the unit panel with the window frame sub-frame. The installation is simple and reduces the dependence of the window installation quality on the skill level of the installer, thereby ensuring the quality of window installation.

[0021] 2) The unit-type fully welded quick-install finished window provided by this utility model has a fully welded frame for both the fixed sash unit panel and the operable sash unit panel, which effectively overcomes the problems of structural looseness and water leakage in the corner bracket assembly corner connection. In addition, welding can also eliminate the gaps generated by the corner bracket assembly corner connection, making the window more beautiful. Attached Figure Description

[0030] In order to more clearly understand the above objectives, features and advantages of the present utility model, the solution of the present utility model will be further described below. It should be noted that the embodiments of the present utility model and the features in the embodiments may be combined with each other on the premise of no conflict.

[0031] In the following description, numerous specific details are set forth to facilitate a full understanding of the present utility model, but the present utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0032] The following combines Figures 1 to 4 to describe the specific embodiments of the present utility model in detail.

[0033] The present embodiment provides a unit-type full-welded quick-install finished window, which includes a window frame sub-frame 1, a fixed sash unit plate 2 and an opening sash unit plate 3.

[0034] Wherein, the window frame sub-frame 1 is formed by connecting a plurality of aluminum alloy profiles through corner connectors.

[0035] It is easy to understand that corner connector connection is a mature technology in the art, and will not be repeated here.

[0036] Specifically, the shape of the window frame sub-frame 1 is not limited. For example, Figure 1 the window frame sub-frame 1 shown in is rectangular.

[0037] Wherein, the fixed sash unit plate 2 includes a first frame body 21 and a first glass 22, and the first frame body 21 is a full-welded frame body.

[0038] Specifically, the first frame body 21 can be designed as a "square" shape, a "day" shape or other common shapes, and the first glass 22 can be correspondingly designed as one piece, two pieces or other quantities. For example, Figure 1 the first frame body 21 shown in is designed as a "square" shape, and the first glass 22 is designed as one piece.

[0039] Wherein, the opening sash unit plate 3 comprises a second frame body 31 and an opening sash body 32, and the second frame body 31 is an all-welded frame body.

[0040] Specifically, the opening sash unit plate 3 may only include the second frame body 31 and the opening sash body 32, and may further include a second glass 33. For example, Figure 1 the middle opening sash unit plate 3 comprises the second frame body 31, the opening sash body 32 and the second glass 33, and the second frame body 31 is designed in a shape of Chinese character "ri".

[0041] Specifically, the opening sash body 32 comprises an opening sash frame 321 and an opening sash glass 322, and the opening sash frame 321 is an all-welded frame body.

[0042] It is easy to understand that the fixed sash unit plate 2 and the opening sash unit plate 3 need to cover the entire area of the window sub-frame 1 to form a fully enclosed window.

[0043] The window structure of the present invention mainly has two improvements: first, the traditional window frame is split into the window sub-frame 1 and the frame bodies of the unit plates; second, the frame bodies of the unit plates and the opening sash frame 321 are all designed as all-welded frame bodies.

[0044] The two above-mentioned improvements are described in detail below respectively.

[0045] The first aspect:

[0046] It should be noted that when the traditional frame body is split into the window sub-frame 1 and the frame bodies of the unit plates, the connection between the unit plates and the window sub-frame 1 is a problem to be solved urgently.

[0047] As shown in Figure 1 and Figure 2 the figures, both the first frame body 21 and the second frame body 31 of the present solution are connected to the inner side of the window sub-frame 1 through spinning members.

[0048] In order to install the spinning members, the aluminum profile of the window sub-frame 1 needs to be designed as follows: the aluminum profile is provided with a mounting cavity 11 extending to both end faces thereof, the cavity wall of the mounting cavity 11 facing the indoor side is open and is provided with a strip-shaped cover body 12, and the cavity wall of the mounting cavity 11 facing the first frame body 21 or the second frame body 31 is provided with an avoiding opening corresponding to the spinning member.

[0049] The specific structure of the spinning machine is as follows: the spinning member comprises a clamping portion 41 and a pressing portion 42, the clamping portion 41 is clamped in the mounting cavity 11, and the pressing portion 42 is rotatably connected to the clamping portion 41 and can penetrate through the corresponding avoiding opening by rotation to press against the first frame body 21 or the second frame body 31.

[0050] During installation, before the corners of the window frame sub-frame 1 are assembled, first slide the spun part into the mounting cavity 11 from the side and slide it to the designated position. Then, align the unit panel with the window frame sub-frame 1. Next, use a wrench to pass through the opening of the mounting cavity 11 and rotate the pressing part 42 of the spun part 90° so that the pressing part 42 passes through the clearance opening and presses the first frame 21 or the second frame 31. Finally, use the strip cover 12 to seal the opening of the mounting cavity 11.

[0051] Specifically, the sliding engagement between the snap-fit ​​portion 41 of the spun part and the mounting cavity 11 can be achieved using a protrusion and groove mating structure. For example, Figure 2 The mounting cavity 11 shown is provided with retaining strips 13 on both the cavity wall facing the first frame 21 or the second frame 31 and the cavity wall away from the first frame 21 or the second frame 31, and the engaging part 41 is provided with a retaining groove corresponding to the retaining strip 13. The engaging part 41 and the mounting cavity 11 are slidably engaged by the cooperation of the retaining strip 13 and the retaining groove.

[0052] like Figure 2 As shown, the locking part 41 is also screwed with a set screw 43, and the pressing part 42 forms a hollow area corresponding to the set screw 43. The set screw 43 abuts against the cavity wall of the mounting cavity 11 facing the outside, causing the locking strip 13 to fit against the locking groove to lock the position of the spun part. Since the locking part 41 of the spun part and the mounting cavity 11 are slidably locked, the position of the spun part relative to the mounting cavity 11 is poorly fixed. This solution adds a set screw 43. After the spun part is moved to the designated position, a tool is used to penetrate the hollow area of ​​the pressing part 42 and rotate the set screw 43, so that the spun part is forced to press against the corresponding structure of the mounting cavity 11, thus achieving the locking of the position of the spun part.

[0053] It should be noted that, according to relevant regulations, the distance between the spinning block and the end of the aluminum alloy profile should be less than 150mm, and the spacing between adjacent spinning blocks should be less than 500mm.

[0054] like Figure 1 and Figure 3 As shown, the aluminum alloy profile at the bottom of the window frame sub-frame 1 is also equipped with multiple height-adjustable leveling components. Each leveling component abuts against the bottom of the fixed sash unit panel 2 or the bottom of the operable sash unit panel 3 to achieve leveling through the cooperation of multiple leveling components. Since both the fixed sash unit panel 2 and the operable sash unit panel 3 are integral unit structures, there is a tendency for horizontal deviation when the unit panels are connected to the inside of the window frame sub-frame 1. The spinning fittings cannot adjust the horizontality of the unit panels. Therefore, this solution adds leveling components to level the unit panels before the spinning fittings press them down.

[0055] The specific structure of the leveling component is as follows: The leveling component includes a bolt 51 that is vertically inserted into the mounting cavity 11. The head of the bolt 51 is limited to sliding on the cavity wall of the mounting cavity 11 facing the first frame 21 or the second frame 31 to limit rotation. The bolt 51 is screwed with a nut 52. The nut 52 is placed in the mounting cavity 11 and abuts against the cavity wall of the mounting cavity 11 away from the first frame 21 or the second frame 31.

[0056] During adjustment, the operator uses a wrench to penetrate the opening of the mounting cavity 11 and tighten the nut 52. The rotation of the nut 52 causes the bolt 51 to move up and down, thereby causing the frame of the unit plate supported on the head of the bolt 51 to move up and down. In this way, the unit plate is leveled by the cooperation of multiple leveling parts.

[0057] It should be noted that since the aluminum alloy profile of the window frame sub-frame 1 located on the bottom side is equipped with both spun parts and leveling parts, the spun parts and leveling parts need to be distributed alternately to ensure both the leveling effect and the clamping effect.

[0058] It should be noted that the window frame sub-frame 1, the fixed sash unit plate 2, and the operable sash unit plate 3 are all composed of two parts: an indoor frame and an outdoor frame. The mounting cavity 11, the spinning parts, and the leveling parts are all arranged corresponding to the indoor frame.

[0059] The second aspect:

[0060] It should be noted that, since the fully welded frame requires heat treatment after welding to eliminate welding stress, and the traditional strip insertion method requires the strips to be inserted before frame assembly, the thermal insulation strips cannot withstand the high-temperature environment of heat treatment, so the traditional strip insertion method is not feasible. For the fully welded frame, the connection between the outdoor welded integrated frame 61 and the indoor welded integrated frame 62 is a problem that urgently needs to be solved.

[0061] like Figure 4 As shown, the fully welded frame of this solution includes an outdoor welded integrated frame 61, an indoor welded integrated frame 62, and a heat-insulating profile 63. The heat-insulating profile 63 is located between the outdoor welded integrated frame 61 and the indoor welded integrated frame 62. The end of the heat-insulating profile 63 facing the outside is snapped and fixed to the outdoor welded integrated frame 61, and the end of the heat-insulating profile 63 facing the inside is fixed to the indoor welded integrated frame 62 by double buckles.

[0062] In order to install the spun parts, the thermal insulation profile 63 and the indoor welded integrated frame 62 need to be designed as follows: the end of the thermal insulation profile 63 facing the interior and the end of the indoor welded integrated frame 62 facing the exterior are both provided with C-shaped grooves 65.

[0063] The specific structure of the double-swivel buckle is as follows: The double-swivel buckle includes a screwing part 641 and a fastening part 642 located on both sides of the screwing part 641. The double-swivel buckle is a long strip structure so that it can be rotated to have an installation state smaller than the opening size of the C-groove 65 and a snap-fit ​​state larger than the opening size of the C-groove 65. When the double-swivel buckle is in the snap-fit ​​state, the two fastening parts 642 are respectively placed in the C-groove 65 of the thermal insulation profile 63 and the C-groove 65 of the indoor welded integrated frame 62, and the screwing part 641 is exposed between the thermal insulation profile 63 and the indoor welded integrated frame 62.

[0064] During installation, the double-hook buckle is placed into the C-groove 65 in the installed state. The screwing part 641 of the double-hook buckle is exposed between the thermal insulation profile 63 and the indoor welded integrated frame 62. The operator uses a tool to rotate the screwing part 641, so that the double-hook buckle switches to the snap-fit ​​state, thereby completing the connection between the thermal insulation profile 63 and the indoor welded integrated frame 62.

[0065] like Figure 4 As shown, since the screwing part 641 of the double-hook needs to be exposed between the thermal insulation profile 63 and the indoor welded integrated frame 62 so that the operator can rotate it, a gap is left between the thermal insulation profile 63 and the indoor welded integrated frame 62. Therefore, a decorative strip 67 can be installed to seal the gap after the double-hook is installed.

[0066] Specifically, the snap-fit ​​structure between the outdoor end of the thermal insulation profile 63 and the outdoor welded integrated frame 61 is not limited. For example, Figure 4 The sawtooth structure 66 is used to achieve the snap-fit ​​fixation between the outdoor end of the thermal insulation profile 63 and the outdoor welded integrated frame 61.

[0067] like Figure 4 As shown, the surface of the fastening part 642 facing the opening of the C-groove 65 is designed as a slope 643 to gradually press the two sides of the opening of the C-groove 65 during rotation. The slope 643 has two functions: first, the slope 643 has a guiding function, which makes it easier for the double-swivel buckle to switch from the installation state to the snap-fit ​​state; second, the slope 643 can gradually press the two sides of the opening of the C-groove 65, which is more conducive to ensuring the clamping force compared to a flat surface.

[0068] During the assembly of the aforementioned fully welded frame, the indoor welded integrated frame 62 and the outdoor welded integrated frame 61 are first welded together. After welding, the indoor welded integrated frame 62 and the outdoor welded integrated frame 61 are heat-treated to remove welding stress. Then, the thermal insulation profile 63 is snapped and fixed to the outdoor welded integrated frame 61 through the serrated structure 66. Finally, the thermal insulation profile 63 is connected and fixed to the indoor welded integrated frame 62 through double buckles. In this way, the connection of the indoor welded integrated frame 62, the thermal insulation profile 63 and the outdoor welded integrated frame 61 is achieved, and the assembly is completed.

[0069] It should be noted that this article only provides a detailed explanation of the key aspects of this solution compared to existing technologies. Figures 2 to 4 For components not mentioned, such as the glass sealing strip 7 and the window sash sealing strip 8, no improvements have been made; existing structural and assembly designs are sufficient.

[0070] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and all should be covered by the protection scope of the claims.
