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 projects, the construction methods for the waterproof joints of the external windows are not uniform, and the gaps between the window frame and the masonry are filled with various types of caulking materials, and the waterproofing effect of the external windows is not uniform.
Common practices include: filling the gap between the outer window frame and the opening of the masonry wall with polymer cement waterproof mortar or foamed polyurethane, but the waterproof effect is not good

Embodiment 1

[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 concrete window sill 1, ...

Embodiment 2

[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 drainage slope on the sid...

Abstract

The invention discloses an outer-window waterproof structure in a masonry project and a construction method of outer-window waterproof structure, belongs to the technical field existing-building renovation and repair, and aims to solve the problem that the outer windows of a historical building are exposed to wind and rain for many years are damaged severely, and the water resistance and seepage resistance of the outer windows cannot satisfy the use function requirements of the building. The outer-window waterproof structure has the advantages that an auxiliary frame and a prefabricated reinforced-concrete sill waterproof node structure are added to the outer side of a window frame, to allow an outer window in the masonry project to have a waterproof and thermal-insulation effect, and theseepage risk of the outer window is lowered; meanwhile, the gap between the window frame and a structure is tightly filled by a foaming agent and sealed by a silicone structural sealant, and the possibility of water seepage of the weak link of the outer window node is avoided; in addition, the lower opening of the sill is provided with a water dripping line and an outward slope to prevent water retention; a good waterproof and seepage preventing effect is achieved by combining the auxiliary frame node structure and the prefabricated reinforced-concrete sill waterproof node structure.
