Description

TECHNICAL FIELD

[0001] The present application relates to the field of door and window structures, in particular to a caulking and leveling anti-cracking structure for a large-joint window frame and a window frame structure. BACKGROUND

[0002] In recent years, 90-degree corner large-view bay windows have been widely used in construction projects. Although such large-view bay windows improve the housing experience, they pose higher requirements for the overall safety, sealing, and wind resistance of the window frame.

[0003] Large-view bay windows often have problems such as non-dense filling of the window frame joints, improper use of materials, and aging. During the living process, residents may find that the wall decoration materials may crack, leak, and mold, and even in extreme weather such as tornadoes, the window frame may be damaged, causing life-threatening conditions.

[0004] The size of the opening joint of the large-view bay window is reserved too large, the outer joint is often greater than 3 cm wide, and the inner joint is 3-5 cm wide, and it is required to complete the caulking and leveling of two processes at one time to save time and cost. The existing window frame joint filling of the large-view bay window is generally performed by manually caulking with ordinary waterproof mortar. This filling method has the following defects: 1. The ordinary waterproof mortar material itself has a large weight of 1800 kg / m 3 and is prone to falling; 2. The adhesion of ordinary waterproof mortar is not enough, generally about 0.2 MPa, and the shrinkage is large, which is prone to cracks at the joint part of the 3-4 cm wide joint window frame or the concrete wall base surface; 3. The hardened surface is rough and not aesthetic. Some large-view bay windows use foaming glue for caulking and leveling. Although this filling method is convenient to construct, it easily pollutes the base surface and affects the next process, and the material is prone to aging and functional failure.
