Description

Technical field:

[0001] The utility model relates to the technical field of external wall seam repairing structures, and more specifically to a repairing structure for preventing external wall thermal insulation from falling off after a window sill cracks. Background technology:

[0002] At present, some buildings have insulation layers on the outside of their exterior walls, and a decorative mortar coating is applied to the outer surface of the insulation layer. Some windows are also set on the exterior walls, and windows and doors are installed inside the windows. The side walls of the windows are not set on the insulation layer. During the use of the building, cracks are easily generated at the window sill due to the uncoordinated thermal expansion and contraction deformation of the insulation board and the cement mortar leveling layer. After the cracks are generated, rainwater easily penetrates into the cracks. Over time, the weight of the insulation layer increases and the strength decreases. Under the long-term and repeated action of external wind loads, it is very easy to detach and fall off, which not only damages the beautiful image of the building, but also easily causes property losses and casualties. Therefore, the repair of cracks in the window sill is a safety and quality issue that needs to be solved urgently. Therefore, a structure that can effectively repair the cracks is needed to avoid the occurrence of the outer insulation layer of the building falling off. Utility model content:

[0019] The buckle plate 3 is in the shape of an angle iron, and its specific structure is similar to a frame. When only one crack 14 appears on the four sides of the window, a single buckle plate 3 is used, and the four sides of the buckle plate 3 are connected to the outer wall 1 and the window frame 2 respectively based on the weather-resistant sealant 4. When multiple cracks 14 appear on the four sides of the window, but not all the four sides of the window have cracks 14, multiple buckle plates 3 can be used, and the weather-resistant sealant 4 is arranged on the four sides of the buckle plate 3 and is in a rectangular ring shape.

[0020] There are cracks 14 around the window on the outer wall 1. The buckle plates 3 on the outer wall 1 are provided with four groups, namely, upper, lower, left and right. The sides of the adjacent buckle plates 3 are formed with oblique cuts and abut against each other. The weatherproof sealant 4 is provided with two groups, which are also rectangular ring-shaped. The weatherproof sealant 4 is distributed on the inner and outer sides of the buckle plates 3.

[0021] The buckle plate 3 is made of a stainless steel plate, or an aluminum alloy plate, and the thickness of the buckle plate 3 is 1 mm; the sides of adjacent buckle plates 3 are fixed together by AB glue.

[0022] The outer surface of the buckle plate 3 is sprayed with a coating layer 5 having the same color as the outer mortar coating 13; the coating layer 5 covers the outer side of the AB glue.

[0023] Working principle: The utility model is a repair structure for preventing the external wall insulation from falling off after the window sill cracks. It is a structure for repairing the window sill cracks, which is mainly divided into two steps: the first step is to use a cement glue mixture 6 of 801 glue and cement to fill the cracks, and the filling should be full; the cement glue mixture 6 is used to repair the cracks and reinforce the insulation layer 12 at the same time;

[0024] The second step is to cover the crack with a buckle plate 3 and fix the buckle plate 3 to the window sill with a weather-resistant sealant 4. Because the buckle plate 3 is L-shaped, it can be pressed on the outer surface of the outer wall 1; it can prevent rainwater from continuing to penetrate into the crack, thereby avoiding the subsequent expansion of the crack.
