Description

Technical Field

[0001] The utility model relates to the technical field of window frames, in particular to a double-layer anti-leakage frame for a window. Background Art

[0002] Aluminum alloy doors and windows are divided into enclosing components or partition components according to their installation positions. They can be designed with different functions according to needs, including thermal insulation, heat insulation, sound insulation, waterproofing, fire prevention and other functions.

[0003] After installation, aluminum alloy windows require glue injection to enhance their sealing and stability. Current methods for preventing aluminum alloy windows from leaking include applying a foaming agent between the window frame and the auxiliary frame, and applying a sealant to the seam between the main frame and the auxiliary frame on the water-facing surface.

[0004] Glue injection at the construction site is a construction operation that is relatively difficult to operate. There are tiny gaps between the foaming agents. After the foaming agent is injected, the foaming agent on the water surface often overflows, requiring operators to cut it and other processing methods. The foaming agent after cutting has gaps, which can easily lead to leakage hazards.

[0005] Moreover, when constructing high-rise windows, there are inherent safety risks. Gluing and cutting each window one by one will increase the workload, especially the top frame of the window, where gluing and cutting are more difficult, often delaying the construction progress.

[0006] The control of the distance between the main window frame and the auxiliary frame relies solely on galvanized steel clips for adjustment and positioning, which is inconvenient and not smooth to install.

[0007] Based on this, the utility model designs a double-layer anti-leakage frame for a window to solve the above problem. Utility Model Content

[0008] The purpose of the utility model is to provide a double-layer anti-leakage frame for a window. The device adds two baffles, and the baffles are tightly clamped with the sealing groove of the main frame, and the anti-leakage effect is significant. The risk of leakage on the water-facing surface can be effectively reduced through the newly added baffle grooves, which saves time and labor. The foaming agent only needs to be filled in the middle isolation point inside the main frame and the auxiliary frame. The foaming agent will not overflow outside the main frame. The operator does not need to cut the foaming agent overflowing on the outside of the water-facing surface. The operation is simple, and there is no need to go out to cut the overflowed foaming agent, which reduces the risk of high-altitude operations.

[0009] The utility model is implemented as follows: a double-layer anti-leakage frame of a window, comprising:

[0010] Main frame profiles and auxiliary frame profiles;

[0011] The main frame profile is a closed tubular straight rod. Four main frame profiles form a square frame structure in the same plane. A limiting notch is provided at the bottom of the main frame profile. The internal cavity of the main frame profile is connected to the outside through the limiting notch.

[0012] Two sealing grooves are provided at the top of the tube cavity of the main frame profile. The sealing grooves are provided on the top of the inner wall of the tube cavity of the main frame profile and are convex downward. The sealing grooves are U-shaped grooves opening downward, and the two sealing grooves are provided parallel to each other.

[0013] The outer edge of the opening of the outer sealing groove and the outer edge of the opening of the limiting notch are on the same vertical plane, and the inner edge of the opening of the inner sealing groove and the inner edge of the opening of the limiting notch are on the same vertical plane;

[0014] The auxiliary frame profile is a closed tubular straight rod, and four of the auxiliary frame profiles form a square frame structure in the same plane; the auxiliary frame profile is clamped around the outer ring of the square frame formed by the main frame profile;

[0015] Two baffles are protruding upward from the top of the attached frame profile. The baffles are straight plates. Each baffle is perpendicular to the top plane of the attached frame profile. The two baffles and the attached frame profile form an integral structure.

[0016] Each of the baffles is inserted into a sealing groove in a one-to-one correspondence, the bottom of the main frame profile is tightly fitted with the top of the auxiliary frame profile, and the splicing gap between the auxiliary frame profile and the main frame profile is sealed and blocked by the sealing groove and the baffle;

[0017] The vertical side walls on both sides of the auxiliary frame profile are provided with clamping grooves, the clamping grooves are inwardly concave U-shaped grooves, and the openings of the clamping grooves are arranged horizontally.

[0018] Furthermore, the top of the raised end of the baffle is an inclined surface, the raised end surface of the baffle is higher on the indoor side than on the outdoor side, and the inclination angle a of the top inclined surface of the baffle is 45°;

[0019] The inclined surfaces of the two baffles are in the same direction and are both inclined toward the outside of the room;

[0020] The baffle and the sealing groove are clearance-matched, and the clearance does not exceed 0.2 mm.

[0021] Furthermore, the side walls of the two baffles are in contact with the edges of both sides of the limiting notch;

[0022] The height h of the baffle is less than the inner cavity thickness b of the main frame profile, and the difference does not exceed 1mm; the height of the baffle is 7mm, and the thickness of a single baffle is 5mm;

[0023] The width c between the two baffles is half of the total width d of the attached frame profile.

[0024] The beneficial effects of the present invention are as follows: 1. The main frame profile of the present invention is increased with a sealing groove, and the auxiliary frame profile is increased with a baffle, and there are double-layer baffles to form a double-layer isolation. The double-layer isolation blocks the splicing gap between the pearlescent and the auxiliary frame on the water-facing surface, forming a water-proof layer, which effectively reduces the risk of leakage;

[0025] 2. The sealing groove and baffle of this device are clamped together, so that the main frame of the window is accurately positioned and the distance between the main frame and the auxiliary frame can be accurately controlled. There is no need to install galvanized steel clamps for clamping, which further reduces the installation steps. While facilitating installation, positioning is also more accurate, effectively shortening the construction period.

[0026] 3. This device also forms three separated cavities in the cavity of the main frame through two layers of baffles. The foaming agent can be filled only in the middle cavity. Then the foaming agent will be blocked by the baffle and the sealing groove and is difficult to overflow. Even if a small amount of foaming agent overflows, it will only overflow in the separate cavities on the front and back sides of the main frame profile, and will not overflow outside the main frame. Not only is the sealing effect good, but there is no need to cut and remove the overflowed foaming agent, avoiding high-altitude operations and making construction simpler.

[0035] See also Figures 1 to 5The utility model provides a double -layer anti -infiltration frame of window, in order to better understand the above technical scheme, below will combine with the specific embodiment of the description of the drawings and the above technical scheme is explained in detail.

[0036] In one embodiment of the utility model technical scheme:

[0037] It includes main frame section bar 1 and attached frame section bar 2;

[0038] Main frame section bar 1 is closed tubular straight pole, and four main frame section bars 1 form a square frame structure in the same plane, and a main frame section bar 1 is clamped on the square glass rim, and the square frame formed by the four main frame section bars 1 in the same plane is sealed and clamped on the outer side rim of the glass, and a limiting notch 12 is formed in the bottom of the main frame section bar 1, and the internal cavity of the main frame section bar 1 is communicated with the outside through the limiting notch 12;

[0039] Two sealing grooves 11 are arranged at the top of the lumen of the main frame section bar 1, and the sealing grooves 11 are arranged in a protruding manner at the top of the inner wall of the lumen of the main frame section bar 1, and the sealing grooves 11 are U-shaped grooves opening downward, and the two sealing grooves 11 are arranged in parallel with each other;

[0040] When the main frame section bar 1 forms a square frame on the glass rim, the two sealing grooves 11 form a ring structure protruding outward and connected in a head-to-tail manner in the same plane, and the planes formed by the two sealing grooves 11 are parallel to each other;

[0041] The opening outer side rim of the outer sealing groove 11 and the opening outer side rim of the limiting notch 12 are in the same vertical plane, and the opening inner side rim of the inner sealing groove 11 and the opening inner side rim of the limiting notch 12 are in the same vertical plane, that is, the outer sealing groove 11 needs to be inserted flush with the outer baffle 21, and the inner sealing groove 11 needs to be inserted flush with the inner baffle 21;

[0042] The attached frame section bar 2 is a closed tubular straight pole, and four attached frame section bars 2 form a square frame structure in the same plane, and the attached frame section bar 2 is clamped around the outer circle of the square frame formed by the main frame section bar 1;

[0043] Two baffles 21 are arranged in a protruding manner upward at the top of the attached frame section bar 2, and the baffle 21 is a straight plate, and each baffle 21 is perpendicular to the top plane of the attached frame section bar 2, and the two baffles 21 and the attached frame section bar 2 form an integral structure;

[0044] The side walls of the two baffles 21 abut against the rims on both sides of the limiting notch 12;

[0045] The height h of the baffle 21 is less than the internal cavity thickness b of the main frame section bar 1, and the difference is not more than 1mm, and the height of the baffle 21 is 7mm, and the thickness of a single baffle 21 is 5mm;

[0046] The width c between the two baffles 21 is half of the total width d of the auxiliary frame profile 2 .

[0047] Each baffle 21 is inserted into a sealing groove 11 in a one-to-one correspondence, and the bottom of the main frame profile 1 is tightly fitted with the top of the auxiliary frame profile 2. When a square frame is formed, the outer circle of the main frame profile 1 is tightly fitted with the inner circle of the auxiliary frame profile 2;

[0048] The inner and outer sides of the joint between the main frame profile 1 and the auxiliary frame profile 2 refer to the indoor and outdoor sides of the assembled window.

[0049] The auxiliary frame profile 2 and the main frame profile 1 form a complete square window frame, and the joint gap between the auxiliary frame profile 2 and the main frame profile 1 is sealed and blocked by the sealing groove 11 and the baffle 21;

[0050] The vertical side walls on both sides of the auxiliary frame profile 2 are provided with positioning grooves 22. The positioning grooves 22 are U-shaped grooves that are recessed inward, and the openings of the positioning grooves 22 are set horizontally. The positioning grooves 22 are buried in the concrete layer or clay plaster layer of the building window, while the main frame profile 1 is exposed outside the building concrete structure. The auxiliary frame is used to position the window body, and the main frame is used to position the glass window. The main frame and the auxiliary frame profiles complete the window frame, and the sliding or openable peeling is finally installed inside the main frame.

[0051] The top of the raised end of the baffle 21 is an inclined surface, the raised end surface of the baffle 21 is higher on the indoor side than on the outdoor side, and the inclination angle a of the top of the baffle 21 is 45°;

[0052] The inclined surfaces of the two baffles 21 are in the same direction and are both inclined toward the outdoor side;

[0053] The baffle 21 and the sealing groove 11 are clearance-fitted, and the clearance does not exceed 0.2 mm.

[0054] It should be noted that:

[0055] 1. Both the main frame profile 1 and the auxiliary frame profile 2 are straight rod-shaped structures. During construction, the window size is measured and then cut and installed. After cutting to the complete size, the auxiliary frame profile 2 is buried in the window opening of the building and then locked on the window concrete with bolts or adhesives to ensure structural stability. The front and rear edges of the auxiliary frame are then smoothed with the paint layer. The positioning groove 22 needs to be buried in the building paint layer or concrete layer. The positioning groove 22 makes the connection between the auxiliary frame and the window building structure more stable. At the same time, the auxiliary frame also needs to be locked with the building structure by bolts; 2. After the frame is installed and ensured to be firm and stable, the main frame is installed. Finally, the main frame and the auxiliary frame form a complete window frame, and then the window with glass is installed. Because the main frame is installed later, it needs to be locked with the auxiliary frame with bolts, and it also needs to be aligned and positioned. These are relatively cumbersome and cannot be standardized. Therefore, construction errors and inaccurate positioning will occur. This device does not require these operations. As long as the baffle 21 is clamped with the sealing groove 11, it can achieve the effect of sealing and isolation and the role of positioning, and installation and construction are convenient.

[0056] When the present invention is in use, the auxiliary frame profile 2 is first buried in the window of the building, and the auxiliary frame profiles 2 need to be installed on the upper, lower, left and right sides of the window to ensure that the four auxiliary frame profiles 2 are on the same plane. The baffles 21 of the two auxiliary frame profiles 2 are connected and aligned, which can ensure that the four auxiliary frame profiles 2 that form the square frame are on the same plane.

[0057] Then use bolts to nail the attached frame profile 2 into and lock it on the window building, apply a finishing layer or concrete, smooth the top platform of the attached frame profile 2 with the building, and ensure that the top of the attached frame profile 2 is uncovered.

[0058] Then install the main frame profile 1, add foaming agent between the two baffles 21 at the top of the auxiliary frame profile 2, and apply sealant on the inner and outer sides of the top of the auxiliary frame profile 2, and then install the main frame profile 1. At this time, the foaming agent will only be in the isolation air formed between the two baffles 21 and the main frame profile 1, and the overflowing foaming agent will fill the cavity between the inner and outer sides of the baffle 21 and the inner and outer sides of the limiting groove 12, and will not overflow outside the main frame profile. There is no need to cut the foaming agent, and the operation is simple.

[0059] When the main frame profile 1 and the auxiliary frame profile 2 are connected, it is sufficient to ensure that the sealing groove 11 is clamped on the baffle 21. No measurement and positioning is required, and no metal buckles need to be installed. The installation is very convenient and the operation is simple.

[0060] This device Figure 2The left side is the outside of the window frame, and the right side is the inside of the window frame. The inside and outside directions referred to in this device refer to the inside and outside of the window, and the inside of the main frame profile 1 refers to the internal cavity of its profile. The orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the present invention.

[0061] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included within the scope of protection of the claims of the present invention.
