Description

Technical Field

[0001] The invention relates to the technical field of anti-leakage, in particular to an anti-leakage structure for an exterior window of a building with a double concave-convex structure and a construction method thereof. Background Art

[0002] In construction projects, leakage of external windows is the most common quality problem during the use of buildings, and is also one of the key projects for construction companies' later maintenance. Especially as my country's residential buildings are becoming increasingly high-rise, the single area of external windows is becoming larger and more wall-based, the common problem of leakage of external windows is particularly prominent. Affected by the construction errors in the installation of external windows, the tongue and groove of the external windows cannot be accurately matched with the window frame, resulting in a gap of about 2 cm between the window frame and the tongue and groove. Later, rainwater will seep into the room along the gap.

[0003] The present invention solves the leakage problem by casting a double concave-convex structure together with the window sill in one go. A 2-centimeter-high anti-ridge cast in one go is added below the window frame. The two tongues and grooves block the infiltration path of rainwater. The self-waterproof property of concrete is utilized to greatly improve the anti-leakage effect of the exterior window. Summary of the Invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 This is a diagram of the anti-leakage structure of the double concave-convex structure exterior window of the present invention;

[0029] Figure 2 It is a construction flow chart of the present invention.

[0030] In the picture: 1 window frame, 2 brick exterior wall, 3 window sill, 4 exterior wall insulation layer, 5 real stone paint, 6 cement mortar layer. DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1 A double concave-convex structure building exterior window anti-leakage structure includes a window frame 1 and a brick exterior wall 2, a window sill 3 is provided on the top of the brick exterior wall 2, an exterior wall insulation layer 4 is provided on the outer surface of the brick exterior wall 2, the outer surface of the exterior wall insulation layer 4 is coated with real stone paint 5, and the outer surface of the brick exterior wall 2 is coated with a cement mortar layer 6.

[0033] Specifically, the thickness of the window sill 3 is 12 cm, and the outer surface of the window sill 3 is provided with a steel film, and the thickness of the steel film is 2 mm.

[0034] Specifically, the steel film has a double concave-convex structure, with two protrusions and two concave holes. The width of the protrusion is 50 mm, and the height of the protrusion is 20 mm, to ensure that the protrusion does not affect the normal installation of the window frame.

[0035] like Figure 2 As shown, the present invention also discloses a construction method of a double concave-convex structure building exterior window anti-leakage structure, comprising the following steps:

[0036] Step 1: First, deepen the layout of the masonry. According to the distance from the bottom of the window to the structural surface, deduct the 12cm window sill, and then layout according to the thickness of the bricks and the thickness of the mortar joints. In addition, the part where the distance from the bottom of the window to the structural surface is less than the thickness of one brick is leveled with a 6-layer cement mortar to reduce the use of irregular small bricks.

[0037] Step 2: According to the deepened shape of the window sill 3, make a steel mold for the window sill, leave a 100mm long casting hole every 400mm at the upper end of the concave and convex mouth of the steel film, pour the concrete, insert the concrete vibrator, and discharge the bubbles after vibration to ensure that the surface of the concrete is not filled with bubbles, tie the window sill steel bars, fix the window sill mold, and pour the window sill concrete;

[0038] Step 3: After the strength of the window sill 3 reaches 80%, use nails to fix the window iron sheet in the reserved notch to fix the four sides of the window frame 1;

[0039] Step 4: Fill the lower gap between the window frame 1 and the brick exterior wall 2 with 6 layers of cement mortar at a ratio of 1:2, and fill the gap with foamed polystyrene or other elastic materials in layers.

[0040] Step 5: Use 1:2.5 cement mortar layer 6 to finish the window outer edge, and make it flush with the window frame 1 after finishing;

[0041] Step 6: Apply 1.0mm thick JS waterproof coating around the outer window. The bonding strength of JS waterproof coating to cement-based surface can reach more than 0.5MPa. It has good bonding performance to most materials, good elasticity, and elongation can reach 200%. In order to improve the comprehensive performance of waterproof layer such as anti-seepage, crack resistance, and flexibility, the waterproof coating needs to press the window frame 120mm, and the overall width should not be less than 200mm.

[0042] Step 7: Construct the exterior wall insulation layer and apply anti-cracking mortar. The anti-cracking mortar has strong bonding strength, crack resistance, waterproofness, antifreeze and high sun protection performance, which can effectively solve the common construction quality problems such as cracking, hollowing and falling caused by ordinary cement mortar used on the exterior wall of the building;

[0043] Step 8: Use inorganic thermal insulation mortar at the window sill position and set it on the wall surface of the building to play the role of thermal insulation, decoration and protection of the building. The mortar opening is not less than 10mm, the whole is sloped outward with a slope of not less than 10%, and the mortar frame is 5mm;

[0044] Step 9: Use real stone paint 5 to construct the brick exterior wall 2. The water absorption rate of real stone paint 5 is relatively low and it is not easy to pollute. The method of real stone paint 5 on the exterior window is the same as that on the brick exterior wall 2;

[0045] Step 10: Construct the plastering and decorative surfaces on the inside of the exterior window, and apply structural sealant at the junction of the window frame 1 and the inner and outer walls.

[0046] To sum up, the double concave-convex structure building exterior window anti-leakage structure and its construction method are achieved by setting a double concave-convex steel membrane on the window sill 3, and leaving a 100mm long casting hole every 400mm at the upper end of the concave-convex mouth of the steel membrane, for pouring concrete, inserting the concrete vibrator and discharging the bubbles after vibration, completing one-time casting and molding, and then using the self-waterproof properties of concrete pouring to block the infiltration path of rainwater, thereby achieving the effect of preventing leakage of exterior windows.
