Description

Technical Field

[0001] The utility model relates to a thermal insulation and waterproof structure, in particular to a thermal insulation and waterproof structure used for window openings of high-rise residential buildings. Background Art

[0002] The thermal insulation decorative integrated board is a building surface material that integrates the thermal insulation layer and the decorative panel layer, is prefabricated in the factory, and then transported to the site for installation. Compared with the traditional external thermal insulation method (first laying the external thermal insulation layer on site and then painting the decorative surface layer), the thermal insulation decorative integrated board has a composite design of the thermal insulation layer and the decorative panel layer, which is safer and not easy to fall off from the exterior wall. The surface material can be flexibly selected according to the facade design, and has good fire resistance and waterproof properties. Since the facade materials of high-rise residential buildings have high requirements for waterproofness and anti-falling, and the thermal insulation design must be taken into account to meet the energy-saving requirements, the thermal insulation decorative integrated board is widely used in high-rise residential buildings due to its superior performance.

[0003] The door and window openings of high-rise residential buildings are important nodes for wind and rainproof, heat preservation and energy-saving design. When using thermal insulation decorative integrated panels as external insulation materials for high-rise residential buildings, the structure of the door and window openings consists of a base wall, a leveling layer, an adhesive layer and a thermal insulation decorative integrated panel. According to the requirements of the "Technical Specification for the Application of Thermal Insulation Decorative Composite Panel Wall Insulation System DG / TJ08-2122-2013": The minimum thickness of the leveling layer of the walls around the outer openings of doors and windows is 12mm; the bonding around the outer openings of doors and windows of high-rise residential buildings should be fully bonded and the thickness should not be less than 5mm; the thickness of the insulation layer should not be less than 20mm, the minimum thickness of the decorative panel is 8mm, and a gap of 5mm-8mm should be left between the thermal insulation decorative integrated panel and the window frame at the door and window closing part, which should be filled with caulking materials and caulked with sealant. It can be seen that the minimum thickness of the thermal insulation decorative integrated panels around the outer openings of doors and windows is 45mm. In actual projects, in order to meet the requirements of energy-saving design, the minimum thickness of the thermal insulation decorative integrated panels around the outer openings of doors and windows is often ≥50mm. The width of the window frame in a high-rise residential building is about 50mm. After the thermal insulation decorative integrated panels are installed around the openings of doors and windows, the window frames are often completely covered by the thermal insulation decorative integrated panels, which can easily cause inconvenience to residents in opening windows and affect the appearance of the facade. In addition, the caulking and sealing materials between the thermal insulation decorative integrated panels and the window frames are prone to loosening and falling off as residents open and close windows for a long time, which cannot meet the requirements of sealing, waterproofing and insulation, resulting in increased energy consumption of the building and leakage at the window nodes.

[0004] According to the specification, drip lines are required on the upper side of the door and window openings and the lower part of the window sills of high-rise residential buildings to prevent rainwater from flowing into the building or flowing down the wall. The traditional drip line is in the form of cement mortar plastering. Since the surface layer of the thermal insulation and decorative integrated board cannot be plastered, the actual construction process often uses the finished "eagle beak" drip line. Although this method can solve the problem of rainwater flowing into the building or flowing down the wall, it often does not look good on the facade and will also increase the construction cost. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a thermal insulation and waterproof structure for window openings of high-rise residential buildings, which is easy to construct and saves construction costs. At the same time, it can ensure that the waterproofness and thermal insulation performance around the window openings are not affected, and the aesthetics of the building facade is not affected.

[0006] The technical solution adopted by the utility model to solve the above technical problems is to provide a thermal insulation and waterproof structure for window openings of high-rise residential buildings, including a decorative panel arranged on a reinforced concrete wall around the window opening, the surface of the decorative panel is coated with an aerogel thermal insulation layer and then fixed to the reinforced concrete wall through a mortar bonding layer and rivets; the decorative panel located on the outer side extends downward to form a window upper drip line on the upper side of the window opening and a window sill lower drip line on the lower side of the windowsill, a cement mortar leveling layer is arranged between the reinforced concrete wall and the mortar bonding layer, and a sealing material layer is arranged on the lower surface of the upper side of the window opening and the upper surface of the windowsill near the window frame and is coated with sealant.

[0007] Furthermore, the thickness of the decorative panel is 8-10 mm, and the height of the downwardly extending section of the decorative panel is 10 mm.

[0008] Furthermore, the thickness of the aerogel thermal insulation layer is 1-2 mm.

[0009] Furthermore, a paint layer with a slope of 5% is formed on the upper surface of the windowsill.

[0010] Furthermore, the thickness of the cement mortar leveling layer is 12-15 mm.

[0011] Furthermore, the thickness of the mortar bonding layer is 5-8 mm.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the thermal insulation and waterproof structure for window openings of high-rise residential buildings provided by the utility model is easy to construct, saves construction costs, and can ensure that the waterproofness and thermal insulation performance around the window openings are not affected, and the aesthetics of the building facade is not affected. The specific advantages are as follows: 1. The thermal insulation layer of the thermal insulation and decorative integrated panel used around the window openings is replaced with a thinner aerogel thermal insulation layer, and the structure of the decorative panel layer superimposed on the thermal insulation layer reduces the thickness of the original thermal insulation and decorative integrated panel construction method; thereby directly avoiding the problem of the original thermal insulation and decorative integrated panel construction method being too thick and affecting the residents' window opening, and also avoiding the problem of increased energy consumption of the building due to loosening and falling of sealing materials and leakage of window nodes. The construction process is simple and convenient for construction, but it does not weaken the waterproofness and thermal insulation performance around the window openings. The structure takes into account the beauty of the facade. 2. For the drip lines on the upper side of the window opening and the lower part of the window sill, the original thermal insulation decorative integrated board is directly treated locally and the decorative panel layer with aerogel applied around the window opening is vertically connected to it and covered with the backing insulation layer. It can be used as the drip line on the upper and lower sides of the window opening, which does not affect the aesthetics of the facade, does not require additional materials, saves fitness costs and prevents rainwater from entering the building.

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Figure 1 The utility model is a schematic cross-sectional structure diagram of a thermal insulation and waterproof structure for a window opening of a high-rise residential building.

[0021] See also Figure 1The utility model provides a thermal insulation and waterproof structure for a window opening of a high-rise residential building, comprising a decorative panel 4 arranged on a reinforced concrete wall 1 around the window opening, wherein the surface of the decorative panel 4 is coated with an aerogel thermal insulation layer and fixed to the reinforced concrete wall 1 through a mortar bonding layer 3 and a rivet 5; the decorative panel 4 located on the outer side extends downward to form a window upper drip line 6 on the upper side of the window opening and a window sill lower drip line 8 on the lower side of the windowsill, a cement mortar leveling layer 2 is arranged between the reinforced concrete wall 1 and the mortar bonding layer 3, and a sealing material layer 10 is arranged on the lower surface of the upper side of the window opening and the upper surface of the windowsill near the window frame 11 and is coated with a sealant 7.

[0022] The utility model provides a thermal insulation and waterproof structure for window openings of high-rise residential buildings. The backing insulation layer 12 of the thermal insulation and decorative integrated board around the window opening is replaced by an aerogel thermal insulation layer painted on the decorative panel 4. The aerogel thermal insulation material is colorless, thin and light, and has a thermal insulation effect. The thickness is generally not more than 2 mm. The decorative panel painted with the aerogel thermal insulation layer is fixed to the base wall through a mortar bonding layer 3 and a rivet 5. The upper surface of the window sill (the lower side of the window opening) is painted with a slope of about 5% to ensure drainage requirements. This structure not only meets the thermal insulation requirements of the window opening, but also reduces the thickness of the thermal insulation and decorative integrated board around the window opening, thereby avoiding the problem that the thickness of the thermal insulation and decorative integrated board structure layer is too high and covers the window frame, causing inconvenience in opening the window, and also avoiding the problem that the sealing material loosens and falls off and cannot meet the requirements of sealing, waterproofing and thermal insulation, thereby causing increased energy consumption of the building. At the same time, this approach also ensures the beautiful effect of the facade.

[0023] On the basis of the above-mentioned method around the window opening, a drip line needs to be designed on the upper side of the window opening and the lower part of the windowsill. The drip line method is to lay out the thermal insulation decorative integrated board perpendicular to the decorative panel material coated with the aerogel insulation layer: the thermal insulation decorative integrated board that peels off the backing insulation layer 12 (about 20mm-30mm) only retains the decorative panel layer. The decorative panel coated with aerogel around the window opening is perpendicularly connected to the thermal insulation decorative integrated board with part of the backing insulation layer 12 peeled off and covers the end insulation layer of the thermal insulation decorative integrated board with part of the backing insulation layer 12 peeled off. The intersection is sealed with a sealing material to ensure the waterproofness and thermal insulation of the thermal insulation layer of the thermal insulation decorative integrated board with part of the backing insulation layer 12 peeled off. The drip line method at the lower edge of the windowsill is consistent with the above method. After removing the thickness of the decorative panel material coated with aerogel, which is about 10mm, the height of the remaining decorative panel is about 10mm, which can be used as the drip line at the top of the window opening and the bottom of the window sill, and the height meets the requirements of the specification. This method directly treats the original thermal insulation decorative integrated board locally to serve as the drip line, without the need for additional drip lines. The process is simple, and no additional materials are required, saving construction costs.

[0024] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the definition of the claims.
