Problems solved by technology

[0002] The repair of the exterior walls of historically protected buildings often involves the repair of masonry projects such as clear water brick walls. Because the exterior windows of historical buildings have been severely damaged by wind and rain for many years, there are many quality problems, and the waterproof and anti-seepage performance of the exterior windows can no longer meet the functional requirements of the continued use of the building.
In the existing masonry pr

Example Embodiment

[0030] Embodiment one

[0031] The main principle of this embodiment is: the dry wall is directly combined with the aluminum alloy imitation steel window, the construction nodes are mainly distributed in the window opening, and whether the window opening leaks mainly depends on whether the quality control during installation and splicing is in place. Usually after the external windows are installed, the surrounding walls will be painted. Window construction can be judged from historical data. In the construction of the waterproof joints of the exterior windows of historically protected buildings, the waterproof requirements must be met while ensuring the construction progress. Therefore, the sub-frame technology is chosen to be used on the exterior windows, and the sealant is used to fill and seal from the inside to the outside.

[0032] like figure 1 and figure 2 As shown, a waterproof structure for exterior windows in a masonry project includes a prefabricated reinforced...

Example Embodiment

[0036] Embodiment two

[0037] Please continue to refer figure 1 and figure 2 , the present embodiment provides the construction method of the exterior window waterproof structure in the masonry project of the present invention, and this construction method comprises the following steps:

[0038] Step 1: Copy and lay out the lines: In order to ensure that the installation position of the doors and windows is accurate and the appearance is neat, the lines should be copied and laid out when installing the doors and windows. Usually, the horizontal line is drawn first, and the ink line is used to bounce it on the brick wall. The multi-storey building is leveled with the opening on the top floor, and the vertical line is used to pop the center line of the window. A single door and window can be hung straight with a wire hammer on site.

[0039] Step 2 Prefabricated reinforced concrete window sill: Carry out prefabricated reinforced concrete window sill construction, and set a ...

Abstract

The invention discloses a waterproof structure for exterior windows in masonry engineering and a construction method thereof, which belongs to the technical field of renovation and repair of existing buildings, and solves the problem that the exterior windows of existing historic buildings have been severely damaged by wind and rain for many years, and the waterproof and anti-seepage performance of the exterior windows has deteriorated. The problem of not being able to meet the functional requirements of the continued use of the building. The exterior window waterproof structure in the masonry project adds sub-frames and prefabricated reinforced concrete window sill waterproof joint structures on the outside of the window frame, so that the exterior windows in the masonry project can achieve waterproof and thermal insulation effects, and reduce the risk of external window leakage. At the same time, the gap between the window frame and the structure is tightly filled with a foaming agent, and sealed with a silicone structural sealant to avoid the possibility of water seepage in the weak links of the outer window nodes. In addition, the drip line is set at the bottom of the window sill, and the bottom of the window is sloped outwards to prevent water from stagnating. The invention achieves good waterproof and anti-seepage effects by combining the way of sub-frame joints and the waterproof joints of prefabricated reinforced concrete window sills into one.
