Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a cavity-free anti-seepage and anti-rust sub-frame system for doors and windows. Background Technology

[0002] In construction projects, door and window installation is a crucial step. Typically, a steel frame (sub-frame) is pre-installed within the concrete frame, and the aluminum window is then connected and fixed to this pre-installed steel sub-frame using screws. This design features a cavity in the sub-frame to facilitate screw installation. However, this construction has several disadvantages:

[0003] Due to the presence of the cavity, when it rains, rainwater will enter the inner cavity through the gaps in the frame or the gaps in the screw holes, forming a water-filled cavity that is not easy to drain. Water will easily accumulate in the inner cavity, and the accumulated water will seep into the room through the gaps in the wall, causing rainwater leakage.

[0004] 2. The steel subframe is prone to rust when exposed to a humid environment for a long time, resulting in poor durability. Utility Model Content

[0005] The purpose of this invention is to provide a cavity-free anti-seepage and anti-rust sub-frame system for doors and windows to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cavity-free anti-seepage and anti-rust sub-frame system for doors and windows, comprising a concrete foundation and a wall, wherein the wall is installed on the concrete foundation, and a stainless steel clip is provided inside the wall, and an aluminum alloy sub-frame is fixedly attached to the top of the stainless steel clip.

[0007] The top of the aluminum alloy subframe is fitted with a door and window frame, and the door and window frame is fitted with door and window glass.

[0008] Preferably, the stainless steel clip is fixedly installed on the concrete foundation using stainless steel nails.

[0009] Preferably, the top of the stainless steel clip is equipped with an elastic clip, and the bottom of the aluminum alloy sub-frame is equipped with an opening groove, and the elastic clip is adapted to the opening groove.

[0010] Preferably, a foam strip is provided inside the opening groove.

[0011] Preferably, the aluminum alloy sub-frame is filled with auxiliary material between itself and the door / window frame, and a sealant is provided between the aluminum alloy sub-frame and the door / window frame.

A stainless steel fixing screw is installed in the screw hole one, and the stainless steel fixing screw is fixedly installed in the screw hole two.

[0013] Preferably, a sealant is provided at the connection between the window glass and the window frame.

[0014] Preferably, the exterior side of the wall is inclined, while the interior side of the wall has a planar structure.

[0015] Preferably, the auxiliary material is a foam material.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The cavity-free waterproof and rust-proof sub-frame system replaces the original cavity-pressed steel frame with cavity-free extruded aluminum alloy profiles, avoiding water accumulation in the sub-frame system. The aluminum alloy sub-frame has open grooves to facilitate the insertion of foam strips, eliminating the original hollow frame while ensuring screw installation and fixing. This eliminates the risk of water leakage caused by water accumulation in the original steel sub-frame, improving the waterproof performance of the window frame. The sub-frame is connected to the wall with stainless steel clips. The entire system uses aluminum alloy and stainless steel, enhancing the system's corrosion resistance and improving product quality and safety reliability. Attached Figure Description

[0022] Please see Figure 1-2This utility model provides a technical solution: a cavity-free anti-seepage and anti-rust sub-frame system for doors and windows, including a concrete foundation and a wall 9. The wall 9 is installed on the concrete foundation, and a stainless steel clip 3 is set inside the wall 9. The top of the stainless steel clip 3 is clipped and fixed to an aluminum alloy sub-frame 2. A door and window frame 6 is installed on the top of the aluminum alloy sub-frame 2, and door and window glass 5 is installed on the door and window frame 6. This utility model designs a special sub-frame cross section, which is formed by pressing aluminum profiles to replace the original steel tube. The original cavity is replaced with an open slot to avoid water accumulation in the original structure. An open slot is set on the back of the aluminum sub-frame to facilitate the insertion of foam strips to separate the concrete, which is convenient for fixing screw installation so that the screws will not hit the concrete after being driven into the steel frame. The aluminum alloy sub-frame is connected to the stainless steel clip, and the stainless steel clip is fixed to the wall by stainless steel nails.
