Embodiment approach
[0068] As another preferred embodiment of the present invention, it also includes:
[0069] A base plate 221 is vertically connected to the bottom of the anchor plate 22, and when the sub-frame 20 is installed, the base plate 221 is attached to the corresponding steel bars in the wall formwork.
[0070] The stability of the sub-frame 20 can be improved by using the provided bottom plate 221 . When the sub-frame 20 is installed, the bottom plate 221 leans against the corresponding wall reinforcement to provide a certain supporting force for the sub-frame 20 . Also preferably, the bottom plate 221 is fixedly connected to the corresponding wall reinforcement.
[0071] The pre-embedded method of the present invention also includes: after the wall body reaches the designed strength, the wall formwork and the window opening formwork are removed, and the auxiliary frame 20 is left on the wall body 11 . Then install window 41 on the square frame body 21 of subframe 20, the main frame...

The invention relates to a sub-frame and its pre-embedded structure and method. The sub-frame is pre-embedded on the wall at the window opening, and the sub-frame includes: a long strip-shaped square frame with a hollow inside to form a cavity; An anchoring plate erected at the bottom of the square frame and embedded in the wall; and a positioning baffle vertically connected to both sides of the square frame and extending to the outside of the square frame, The upper surface of the positioning baffle is flush with the lower surface of the bottom of the square frame. The subframe of the present invention can be constructed together with the wall, and can be positioned and installed with the window formwork at the window opening through the positioning baffle, and the subframe is clamped by the window formwork, and the subframe and the window formwork are used as the formwork of the window opening, which realizes The positioning and installation of the sub-frame is completed at the formwork installation stage, which solves the problem of on-site hole measurement and installation of the traditional sub-frame, and reduces the workload of construction procedures and cross operations.
Description
technical field [0001] The invention relates to the field of window structure engineering, in particular to an auxiliary frame and its pre-embedded structure and method. Background technique [0002] In the field of construction, water seepage of exterior walls, damage and pollution of windows is a common quality problem that is difficult to solve, and it is also one of the quality problems that owners complain more about. In order to prevent the windows from being damaged and polluted, most of the windows are installed by the dry method now, that is, the secondary frame is installed after the wall of the opening is formed, and the surface of the hole is waterproofed, heat-preserved and decorated, and then the window is installed on the secondary frame after completion . [0003] Although this type of installation method facilitates the installation of the window, improves the installation accuracy of the opening, and prevents the finished window from being polluted by cons...
