[0002] Window sills have become an indispensable part of home decoration, and they come in a variety of materials, including marble, granite, artificial stone, decorative panels, and decorative wood trim.
[0003] When constructing a window sill, it is necessary to first pour a window sill plate on the window frame, then install the window on top of the foundation of the window sill plate. After the window is installed, the window sill plate is laid on the interior side. For unfinished units, the owner needs to purchase this separately. The window sill plate also needs to be roughened before concrete is poured to fix the window sill plate and the window sill plate together. At the same time, formwork is erected to provide auxiliary support for the window sill plate. After the window sill plate is completely fixed to the window sill plate, the whole process is time-consuming and expensive, which is not suitable for today's fast-paced lifestyle. Therefore, shortening the construction efficiency and construction period as much as possible is a common demand of the majority of homeowners. Utility Model Content

[0014] like Figure 1-2 As shown, the interior window construction structure includes a wall 1, a window frame 4, a window sill plate 3, and a window sill board 5. The top of the wall 1 is fixed to the window sill plate 3 through a mortar layer 2. The top end face of the window sill plate is fixed to a vertically installed window frame 4. The side of the window frame 4 closest to the interior has a horizontally installed window sill board 5. The bottom end face of the window sill board 5 is fixedly connected to the top end face of the window sill plate 3. The window sill plate 3 has a horizontally arranged threaded post 6 on the side closest to the interior. A vertical bracket 7 is fitted on the threaded post 6. A fastening nut 10 is screwed onto the threaded post 6 on the outside of the vertical bracket 7. A horizontal bracket 8 is fixed to the top of the vertical bracket 7. The top end face of the horizontal bracket 8 is fixedly connected to the bottom end face of the window sill plate 5. Through the support of the vertical bracket 7 and the horizontal bracket 8, the problems of formwork during the installation of the window sill plate 5 can be reduced. At the same time, the horizontal bracket 8 can also provide stability to the window sill plate 5 during later use.
[0015] The window sill pressure plate 3, window sill 5, horizontal bracket 8, and vertical bracket 7 are all manufactured in the factory and delivered to the construction site for direct installation. During the installation process, the vertical bracket 7 contacts and limits the movement of the inner wall of the wall 1, ensuring that the window sill pressure plate 3 is installed in place. This greatly reduces the workload of on-site construction and speeds up the work efficiency.
[0016] The window sill plate 3 includes an integrally formed horizontal part 3.1, a vertical part 3.2, and an inclined part 3.3; the bottom end face of the inclined part 3.3 is provided with a water-blocking recess, and the water-blocking recess is arranged along the length direction of the prefabricated window sill plate 5.
