Description

Technical Field

[0001] The utility model relates to the technical field of window opening structures, in particular to a window opening structure used in an external wall internal insulation system. Background Art

[0002] At present, with the gradual expansion of the scale of engineering construction, high-rise buildings have become the main form of current buildings, especially residential buildings. With the current requirements for comfort and energy saving, internal insulation of exterior walls has become the main design form for energy saving in current buildings. At present, residential buildings generally have a large number of bay window structures. Because the bay window part is an outward-convex concrete structure with poor energy-saving performance, it is necessary to lay internal insulation and energy-saving materials for covering, and there is a handover construction with aluminum alloy window frames.

[0003] The current conventional window opening insulation treatment method is to directly lay it on the edge of the aluminum alloy window frame according to the size of the window opening. However, there are still some shortcomings. When the height of the aluminum alloy window frame is low, the thickness of the insulation layer will be higher than the window frame and glass, affecting the indoor sensory experience and lighting. The insulation layer needs to be removed during the subsequent decorative layer construction, affecting the indoor insulation and energy-saving effects. In order to ensure the lighting effect of the window frame, the thickness of the insulation layer is reduced or a concrete step is constructed on the edge of the window frame in the traditional way, forming a cold bridge around the window frame. In cold winter and hot summer weather, condensation is prone to occur around the window frame. In order to ensure the thickness of the insulation layer, the height of the window frame is reduced in the traditional way, and the gap between the window frame and the structure is increased, resulting in an increased risk of leakage at the edge of the window frame. Therefore, a window opening structure for an exterior wall internal insulation system is proposed to solve the above problems. Utility Model Content

[0006] The special tongue and groove comprises a bottom supporting sill fixed on the bottom wall of the inner surface of the window wall, and the top of the bottom supporting sill is fixed with an anti-seepage positioning sill which fits the top wall, front wall and rear wall of the inner surface of the window wall.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 In this embodiment, a window opening structure for an exterior wall internal insulation system includes a window wall 1 and a floor slab 2. It should be noted that the floor slab 2 is located on the left side of the window wall 1. The left and right sides of the window wall 1 are respectively outdoors and indoors. The right side of the window wall 1 is outdoors, and the connection between the right side and the window frame 4 needs to be leak-proofed.

[0023] Furthermore, a special groove 3 is fixed to the inner surface of the window wall 1, and a window frame 4 is fixed to the bottom of the inner surface of the special groove 3. The window frame 4 is made of aluminum alloy, and a glass 5 is fixed to the inner surface of the window frame 4. The top, front and rear sides of the window frame 4 are fixed with galvanized fixing plates 6 fixed to the window wall 1. The galvanized fixing plates 6 are corrosion-resistant, thereby extending their service life. It should be noted that the galvanized fixing plates 6 are Z-shaped, and the Z-shaped galvanized fixing plates 6 can be fixed to the upper and lower sides through a multi-layer structure. The three galvanized fixing plates 6 are fixed to the window frame 4 and the window wall 1 respectively by a plurality of bolts. The galvanized fixing plates 6 can be firmly fixed to the window frame 4 and the window wall 1 by the bolts, so that they are firmly fixed and the sealing is increased. The thickness of the galvanized fixing plates 6 is 0.5 mm. The thinner galvanized fixing plates 6 can almost ignore their thickness, and their auxiliary fixation and further blocking of external moisture and rainwater can greatly increase the effect of preventing infiltration.

[0024] In addition, the top and bottom of the inner surface of the window wall 1 are fixed with an insulation layer 7. The insulation layer 7 is achieved by taking measures on the building's external protective structure to reduce the dissipation of indoor heat from the building to the outdoors, thereby maintaining the indoor temperature of the building. Building insulation materials play an important role in creating a suitable indoor thermal environment and saving energy in building insulation. The window frame 4 and the top wall of the inner surface of the window wall 1 are filled with foam glue 8. The foam glue 8 can fill the gap between the window frame 4 and the window wall 1, and continue to expand under chemical reaction to fill the gap, further increasing the sealing of the window frame 4 and preventing external moisture and rainwater from penetrating into the interior.

[0025] During the construction process, the special groove 3 is cast at one time according to the insulation thickness in the window during the construction stage of the bay window structure, which can ensure the construction thickness of the insulation layer 7, achieve energy-saving effects, and prevent rainwater from penetrating inwards through its blocking effect.

[0026] See also Figure 4 In order to achieve the effect of anti-leakage, the special groove 3 in this embodiment includes a bottom supporting sill 301 fixed to the bottom wall of the inner surface of the window wall 1, and the window frame 4 is fixed to the top of the bottom supporting sill 301 by bolts. The bolts can pass through the window frame 4 and be threadedly fixed to the bottom supporting sill 301, thereby firmly fixing the window frame 4 on the bottom supporting sill 301.

[0027] In addition, an anti-seepage positioning sill 302 that fits the top wall, front wall and rear wall of the inner surface of the window wall 1 is fixed on the top of the bottom supporting sill 301. The bottom supporting sill 301, the anti-seepage positioning sill 302 and the bottom drainage slope 303 are all concrete cast in a mold, which is realized by secondary deepening processing and transformation using an aluminum alloy formwork, and is formed in one-time construction with the main structure, so that the bottom supporting sill 301, the anti-seepage positioning sill 302 and the bottom drainage slope 303 are firmly fixed on the inner side of the window wall 1.

[0028] It should be noted that the three anti-seepage positioning sills 302 are flush with the right side wall of the window wall 1 on the side facing the outside, and are flush with the left side wall of the window frame 4 on the side facing the inside. The thickness of the thermal insulation layer 7 is equal to that of the bottom supporting sill 301 and the anti-seepage positioning sill 302. The height and thickness of the thermal insulation layer 7 are the same as those of the bottom supporting sill 301 and the anti-seepage positioning sill 302. It will be very beautiful after installation, and it can prevent the thermal insulation layer 7 from covering the window frame 4 and the glass 5 after construction, resulting in an unsightly appearance.

[0029] It should be noted that a bottom drainage slope 303 is provided on the top of the bottom supporting sill 301. The bottom drainage slope 303 directs rainwater outward to prevent water seepage caused by water accumulation and backflow. The starting point of the bottom drainage slope 303 is an area ten to twenty millimeters to the left of the right side of the bottom of the window frame 4, which is convenient for subsequent sealing and gluing of the connecting gaps. By guiding the slope of rainwater, it is ensured that outdoor rainwater can be prevented from leaking when the indoor insulation is closed.

[0030] In general, the insulation layer 7 has the same height and thickness as the bottom support sill 301 and the anti-seepage positioning sill 302, and is beautifully decorated. Rainwater is guided outward through the bottom drainage slope 303 to prevent water accumulation and seepage caused by backflow.

[0031] The working principle of the above embodiment is:

[0032] During the installation process, the window frame 4 is installed against the anti-seepage positioning sills 302 on the top and the front and rear sides, and the bottom is fixed on the bottom supporting sill 301. First, the three galvanized fixing plates 6 are fixed to the inner surface of the window wall 1 by bolts, and the window frame 4 is fixed to the bottom supporting sill 301 by bolts. Finally, the window frame 4 and the three galvanized fixing plates 6 are fixed together by bolts to complete the installation. Fill the space between the window frame 4 and the top wall of the inner surface of the window wall 1 with foam glue 8, and caulk the joints of the window frame 4 to further improve the sealing effect. The rainwater is guided outward through the bottom drainage slope 303 to prevent water seepage caused by accumulation of water and backflow, and the anti-infiltration effect is good.
